Description

TECHNICAL FIELD

The present invention relates to the technical field of metallurgy, in particular to a sampling probe, an automatic separation device, and a use method thereof.

BACKGROUND

In metallurgical production, it is necessary to determine the variety and quantity of additives and the end point of smelting according to the temperature, carbon content and other chemical compositions of molten metal in the molten pool. In order to accurately obtain the content of these chemical compositions, samples need to be taken and sent to the laboratory for analysis by means of a pneumatic sample sending device. At present, the smelting area is mostly measured by mounting a composite probe for temperature measurement and sampling on a temperature measuring gun and then manually inserting the temperature measuring gun into smelting liquid. With regard to the separation operation of the probe sample after sampling, it is usually adopted in a manual manner in the prior art, thus restricting the overall automation level of the smelting area.

The outer side of the currently used sampling probe consists of a tubular paper housing, and the inner side of the probe has various forms according to different metal sample mold boxes. One of the more common forms is a cylindrical flat sample, and a housing of a mold box for the sample is of a two-piece structure which is fixed into a whole by a metal clamp. This metal clamp is used to ensure that the two-piece mold box housing is always kept in the combined state in the process that the sampled molten metal is solidified therein, so that the obtained solidified sample of the molten metal is a regular cylinder with no burr at the edge.

Chinese patent CN203545142U discloses a device for automatically exposing a sample, wherein a probe is first fixed by a supporting device on its outer surface, the probe with the sample is partitioned by a partitioning device, and the sample with a housing is squeezed out from the partitioned area of the probe by means of a punch. A filling material including the housing and the sample is introduced into a housing dismantling device through an introduction device, wherein the housing includes a clamp for keeping the sample housing closed while sampling. The housing dismantling device includes a bottom plate, a vibration motor, a centrifugal device, a colliding body, and the like. The bottom plate inclines downwards, and the bottom of the bottom plate is provided with the vibration motor. By means of the vibration of the bottom plate, the sample is moved towards the centrifugal device in the housing dismantling device. The gap below the centrifugal device is sized only to pass the separated sample and housing, and the unseparated sample and housing obtains an impulse towards the colliding body by the centrifugal device. By the collision of the colliding body, the object will be disassembled in most cases. The disassembled sample, housing and filling material pass through the gap below the centrifugal device to move towards a sample extraction area. Before reaching the sample extraction area, the disassembled sample, housing and filling material are blocked by a blocking layer on which a channel for the housing and the filling material is arranged, so that the housing and the filling material are separated through the channel, and the sample cannot pass through the channel due to its size, therefore the sample is guided by the blocking layer and finally enters the sample extraction area. The device has a large number of actuation mechanisms, complex structure, high cost, heavy post-maintenance work and the reliability is difficult to guarantee. The method of enabling the housing component with the clamp to hit the colliding body by means of the centrifugal device can only ensure that the sample is separated from the housing in most cases, but it is difficult to deal with a situation when the clamp is assembled too tight and difficult to separate the sample from the housing. Moreover, the device has no constraint on the posture of each component, so that jamming at the gap between the centrifugal device and the bottom plate will easily occur due to arbitrary postures of the components.

SUMMARY

In view of the above-mentioned deficiencies in the prior art, an objective of the present invention is to provide a sampling probe, an automatic separation device, and a use method thereof, which can not only effectively solve the problem of hard separation between the sample and the housing, but also avoid the jamming between the actuation mechanism and the components by the constraint on the posture of each component.

In order to achieve the above objective, the present invention adopts the following technical solution.

  • wherein a first posture adjustment device, a first separation device, a second posture adjustment device, and a second separation device are sequentially arranged between the front end of the inclined bottom plate and the rear end of the inclined bottom plate.

DETAILED DESCRIPTION

In order to be able to better understand the above technical solutions of the present invention, the technical solutions of the present invention will be further explained in conjunction with the accompanying drawings and the embodiments.

Referring to FIGS. 1 and 2, a sampling probe provided by the present invention includes a probe tail area 1 and a probe sampling area 2 connected to the top of the probe tail area 1; the probe sampling area 2 includes a paper housing, a two-piece mold housing component 3 disposed in the paper housing, and a sample 4 disposed in the two-piece mold housing component 3; the two-piece mold housing component 3 is wound and fixed by an adhesive tape capable of burning and melting.

In an automatic separation device of the present invention, the cutting device 5 places the sampling probe, whose sampling is completed, in a direction perpendicular to the acting direction of the cutting device 5 in FIG. 1, so as to cut the sampling probe into two parts, i.e., the probe tail area 1 and the probe sampling area 2. The cutting plane formed by the acting direction of the cutting device 5 is located at the guide channel 6 of the flat cylinder and the two-piece mold housing component 3 and is tangent to the cylindrical side face formed when the two-piece mold housing component 3 is in the combined state. The function of the cutting device 5 is to extrude and deform the paper housing of the sampling probe, and the deformed opening shape is favorable for the two-piece mold housing component 3 and the sample 4 to fall out.

The two-piece mold housing component 3 is wound and fixed by an adhesive tape capable of burning and melting during assembly, and during sampling, the two-piece mold housing component 3 is kept in the combined state under the action of the adhesive tape capable of burning and melting; after the sample 4 is taken, the adhesive tape capable of burning and melting is burned and melted by molten metal, and then, the molten metal entering the two-piece mold housing component 3 through the guide channel 6 is solidified into a solid state. By the action of the cutting device 5, the sample 4 in the two-piece mold housing component 3 and shank-shaped metal formed by the high-temperature metal flowing through the guide channel 6 will be broken and separated, and the sample 4 is a regular flat cylinder.

As shown in FIG. 3, a sampling probe automatic separation device provided by the present invention includes a cutting device 5 for cutting a sampling probe, and an inclined bottom plate located downstream of the cutting device 5.

The inclined bottom plate inclines downwards from the front end to the rear end, the upper end (i.e., the front end) of the inclined bottom plate is placed close to the cutting device 5; the lower end (i.e., the rear end) of the inclined bottom plate is far away from the cutting device 5 and is lower than the horizontal plane where the front end is located.

Preferably, the downward inclination angle of the inclined bottom plate is 30°, i.e., the included angle between the inclined bottom plate and the horizontal plane is 30°.

In some embodiments, the inclined bottom plate can include a first inclined bottom plate 7, and a second inclined bottom plate 8 connected to the lower end (or the rear end) of the first inclined bottom plate 7. In this embodiment, the first inclined bottom plate 7 and the second inclined bottom plate 8 are the same plate.

A first posture adjustment device 9, a first separation device 10, a second posture adjustment device 11 and a second separation device 12 are sequentially arranged between the upper end of the inclined bottom plate and the lower end of the inclined bottom plate.

After the sampling probe is cut by cutting device 5, the probe sampling area 2 falls onto the first inclined bottom plate 7, and the probe sampling area 2 changes from horizontal state to a state of sliding down along the first inclined bottom plate 7.

The first posture adjustment device 9 includes a constraining collision point 901 (the constraining collision point 901 in this embodiment is a slender rod), a turnover collision point 902 (the turnover collision point 902 in this embodiment is also a slender rod) and a plurality of guide points 903 (the guide point 903 in this embodiment is a guide rod, i.e., slender rod, which can play a role in guiding according to the set position), which are arranged in sequence from the upper end of the inclined bottom plate to the lower end of the inclined bottom plate and are all mounted on the upper surface of the first inclined bottom plate 7. In this embodiment, the turnover collision point 902 provides one turnover collision point, and the constraining collision point 901 provides one constraining collision point, but the present application does not limit the number of turnover collision points and constraining collision points. The slid down end face of the probe sampling area 2 collides with the turnover collision point 902 (as shown in FIG. 4), and the side face of the probe sampling area 2 collides with the constraining collision point 901 and then is laterally overturned so that the open side of the two-piece mold housing component 3 with the sample 4 gradually faces downwards and is guided by the guide points 903 to fall into the first separation device 10.

The first separation device 10 includes a first side plate 1001, a second side plate 1002 and a turnover plate 1003.

The first side plate 1001 and the second side plate 1002 are mounted on the upper surface of the first inclined bottom plate 7, thereby forming a first chute 1005;

• • the first inclined bottom plate 7 under the first side plate 1001 and the second side plate 1002 where the first chute 1005 is located is provided with a drop opening 1004, the turnover plate 1003 is connected to the lower surface of the inclined bottom plate and covers the drop opening 1004, and the size of the drop opening 1004 ensures the probe sampling area 2 to pass smoothly.

The first chute 1005 is arranged as a structure that gradually becomes smaller, the minimum size of an outlet at the lower part of the first chute 1005 is greater than the maximum size of the two-piece mold housing component 3 and smaller than the cross-sectional diameter of the probe sampling area 2, so as to separate the paper housing of the probe sampling area 2 from the two-piece mold housing component 3 inside the paper housing.

A drop opening 1004 is formed between the first side plate 1001 and the second side plate 1002, and an outlet of the first chute 1005 is formed between the lower end of the first side plate 1001 and the lower end of the second side plate 1002. The turnover plate 1003 is connected to the lower surface of the first inclined bottom plate 7 by an adjustable hinge 1006 and can cover the position of the drop opening 1004 (as shown in FIG. 5).

The probe sampling area 2, which is laterally overturned with the open side facing gradually downwards, rushes into the first chute 1005 due to inertia, at this moment, there is no force between the probe sampling area 2 and the first inclined bottom plate 7. The open side of the probe sampling area 2 collides with the side plates at the outlet at the lower part of the first chute 1005, and the probe sampling area 2 intercepted in the first chute as its size cannot pass through the outlet of the first chute 1005; the sample 4 of the probe sampling area 2 and the two-piece mold housing component 3 can then continue to rush out of the outlet at the lower part of the first chute 1005. The paper housing of the probe sampling area 2, by its own gravity action, enables the turnover plate 1003 mounted to the lower surface of the first inclined bottom plate 7 to be overturned downward and passes through the drop opening 1004 to fall out of the separation device, so that the separation of the paper housing of the probe sampling area 2 from the sample 4 and the two-piece mold housing component 3 is completed.

The heights of the first side plate 1001 and the second side plate 1002 should be at least greater than the cross-sectional radius of the probe sampling area 2, so as to prevent the probe sampling area 2 from being directly overturned out of the first side plate 1001 and the second side plate 1002 due to inertia.

The second posture adjustment device 11 includes a second chute 1101 mounted on the upper surface of the second inclined bottom plate 8 and used for adjusting the postures of the sample 4 and the two-piece mold housing component 3. The inner wall of the second chute 1101 is arranged as a curved surface 1102 with varying angles, and an inlet 1103 of the second chute 1101 communicates with the outlet of the first chute 1005. The sample 4 and the two-piece mold housing component 3 sliding off from the first chute 1005 pass through the second chute 1101 to be adjusted stepwise from an arbitrary posture to a near upright state, i.e., a state of rolling along the side of the mold housing component 3 and enter the second separation device 12.

The second separation device 12 includes a third side plate 1201 with an inclination angle and a fourth side plate 1202 with inclination angle, and a third chute 1203 is formed between the third side plate 1201 and the fourth side plate 1202.

The third side plate 1201 and the fourth side plate 1202 are connected to the upper surface of the second inclined bottom plate 8, the upper ends of the third side plate 1201 and the fourth side plate 1202 are arranged facing the upper end of the inclined bottom plate, and the lower ends of the third side plate 1201 and the fourth side plate 1202 are arranged facing the lower end of the inclined bottom plate. The third side plate and the fourth side plate are gradually outwards overturned in the direction from the front end of the inclined bottom plate to the rear end (or the angles of inclination of the third side plate and the fourth side plate in opposite directions gradually increase). The distance between the third side plate 1201 and the fourth side plate 1202 gradually becomes larger from the front end to the rear end.

An inlet of the third chute 1203 communicates with an outlet 1105 of the second chute 1101, and the size of the inlet of the third chute 1203 should be greater than the height of a cylinder formed when the two-piece mold housing component 3 is in the combined state and smaller than the diameter of the cylinder formed when the two-piece mold housing component 3 is in the combined state.

The sample 4 is a standard flat cylinder, which is in an upright state when entering the second separation device 12, then rolls and slides along a straight line in the third chute 1203, and is always located at the centerline position of the third chute 1203, whereas due to having a chamfer, the two-piece mold housing component 3 gradually changes from an upright state to a state of rolling along the third side plate 1201 and the fourth side plate 1202 during sliding. Since the angles of outward inclination of the third side plate 1201 and the fourth side plate 1202 gradually increase, and the third chute 1203 gradually widens from the front end to the rear end, the two-piece mold housing component 3 will gradually deviate from the centerline of the third chute 1203, and the distance between the two-piece mold housing component 3 and the sample 4 is larger and larger until the two-piece mold housing component 3 and the sample 4 are completely separated, then the sample 4 falls into a sample extraction area 1204 located at the outlet of the third chute 1203.

Referring again to FIG. 4, the distance between the turnover collision point provided by the turnover collision point 902 and the constraining collision point provided by the constraining collision point 901 and the first inclined bottom plate 7 is not smaller than the radius of the end face of the probe sampling area 2; if the probe sampling area 2 is divided into left and right areas as shown in FIG. 4 with reference to an axial section perpendicular to the first inclined bottom plate 7, the turnover collision point and the constraint collision point should be located in the same area.

Referring again to FIG. 5, the lower surface of the first inclined bottom plate 7 at the drop opening 1004 is provided with a downwards overturned turnover plate 1003 by means of an adjustable hinge 1006. The probe sampling area 2, which rushes into the first chute 1005 by inertia, collides with the outlet at the lower part of the first chute 1005. the sample 4 and the two-piece mold housing component 3 slide into the second chute from the outlet, and the paper housing of the probe sampling area 2 can overturn the turnover plate 1003 downwards by its own gravity, so as to fall out from the drop opening 1004 to complete the separation of the paper housing of the probe sampling area 2 from the sample 4 and the two-piece mold housing component 3. In addition to realizing the overturning of the turnover plate 1003 through the adjustable hinge 1006, the opening and closing of the turnover plate 1003 can be controlled by means of an air cylinder. Furthermore, due to its own inertia, the probe sampling area 2 will not fall out of the drop opening 1004 since there is no force acting between the probe sampling area 2 and the first inclined bottom plate 7 before the probe sampling area 2 collides with the outlet of the first chute 1005, so that the turnover plate 1003 can be omitted in some embodiments.

Referring to FIG. 6, the inner wall of the second chute 1101 is set as a curved surface 1102 with varying angles, the curved surface 1102 is parallel to a bottom plate 1104 of the second chute 1101 at the inlet 1103 of the second chute 1101, and the curved surface 1102 is perpendicular to the bottom plate 1104 of the second chute 1101 at the outlet 1105 of the second chute 1101.

Referring to FIG. 7, in which a first embodiment of the third chute 1203 is shown.

Two partitioning plates 1205 are mounted on the inclined bottom plate at the outlet position of the third chute 1203. The sample extraction area 1204 is located at the end of the outlet position of the third chute 1203 and located between the two partitioning plates 1205. The sample 4 rolls and slides along a straight line on the centerline of the third chute 1203, slides into the channel between the two partitioning plates 1205 and falls into the sample extraction area 1204 below, whereas due to having a chamfer, the two-piece mold housing component 3 will roll against the third side plate 1201 and the fourth side plate 1202, slides into the channel between the partitioning plates 1205 and the third side plate 1201 and the channel between the partitioning plates 1205 and the fourth side plate 1202, and falls into a mold housing component collection area.

Referring to FIG. 8, in which a second embodiment of the third chute 1203 is shown. The centerline of the inclined bottom plate at the outlet position of the third chute 1203 is provided with a rectangular opening 1206. The edge of the rectangular opening 1206 close to the sample extraction area 1204 (i.e., the end of the rectangular opening) is provided with a blocking plate 1207. The sample extraction area 1204 is located below the rectangular opening 1206. The sample 4 rolls and slides along a straight line on the centerline of the third chute 1203 and falls into the sample extraction area 1204 below from the rectangular opening 1206, whereas due to having a chamfer, the two-piece mold housing component 3 will roll against the third side plate 1201 and the fourth side plate 1202, slides out from the outlet of the third chute 1203 and falls into the housing component collection area.

Referring to FIG. 9, the present invention also provides a use method of the automatic separation device, including the following steps:
