1. Field of the Invention
This invention relates to a forcing and fixing structure for filter cylinders, particularly to one installed in a filter cylinder type duct collector.
2. Description of the Prior Art
A conventional filter cylinder type dust collector and a filter cylinder assembling-and-disassembling mechanism are disclosed in
In view of the defects mentioned above, the inventor of this invention thinks that the filter cylinder assembling-and-disassembling mechanism 6 of the conventional filter cylinder type dust collector has to be ameliorated and hence devises this invention.
The objective of this invention is to offer a forcing and fixing structure for the filter cylinders of a filter cylinder type dust collector, convenient for a user to assemble and disassemble plural filter cylinders in a filter cylinder type dust collector and able to surely force the filter cylinders to tight fit with a division plate to attain good airtight effect and enhance efficacy of air purification as well as quality of use of the filter cylinder type dust collector.
The forcing and fixing structure for the filter cylinders of a filter cylinder type dust collector in the present invention includes a dust collector formed with a housing, which has its interior provided with an accommodating space and its topside bored with an air outlet communicating with the accommodating space. The housing of the dust collector further has one side formed with an air intake communicating with the accommodating space and another side assembled with a door plank. The dust collector is installed with a motor fan at an upper side of the accommodating space, and a division plate is provided at an intermediate section of the accommodating space, bored with a plurality of through holes spaced apart. Plural filter cylinders respectively corresponding with the through holes are positioned under the division plate and plural dust collecting barrels are disposed under the filter cylinders. This invention is characterized by plural setting racks, plural forcing rods and plural assembling-and-disassembling plates. The setting racks are in pair and in parallel provided under the division plate and each pair of the setting racks is fixed at two sides of the through hole of the division plate and further, respective setting rack is axially formed with an accommodating groove. The forcing rods corresponding with the setting racks are in pair fitted with the corresponding accommodating grooves of the setting racks, and the sections of the forcing rods are unequal diameter and formed with a major diameter section and a minor diameter section. In addition, the forcing rods respectively have one end vertically connected with a rotary handle, and the rotary handles corresponding with the forcing rods are provided in pair and can be locked in place by a locking member. The assembling-and-disassembling plates are respectively disposed on the twinned forcing rods and respectively bored with plural openings corresponding with the through holes of the division plate for the filter cylinders to be inserted therein.
The forcing and fixing structure for the filter cylinders of a filter cylinder type dust collector in the present invention is to have the twinned rotary handles turned to actuate the forcing rods to rotate and simultaneously, the forcing rods whose sections are unequal diameter will drive the assembling-and-disassembling plate to move upward and force the filter cylinders to tight fit with the division plate, thus enhancing convenience in assembly and disassembly of filter cylinders, attaining good airtight effect and elevating effect of air purification and quality of use of the filter cylinder type dust collector.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of a facing and fixing structure for the filter cylinders of a filter cylinder type dust collector in the present invention, as shown in
The dust collector 300 consists of a housing 10 having its interior formed with an accommodating space and its topside provided with an air outlet 12 communicating with the accommodating space 11. The housing 10 has one side bored with an air intake 13 communicating with the accommodating space 11 and another side provided with a door plank 14 assembled thereon with a container type door handle 15. The accommodating space 11 of the dust collector 300 has an upper side installed with a motor fan 20 and an intermediate section provided with a division plate 30, which is bored with a plurality of through holes spaced apart and in this preferred embodiment, the division plate 30 has its underside provided with a plurality of annular projecting edges 32 respectively positioned at the circumference of the through holes 31. Further, plural filter cylinders 40 respectively corresponding with the through holes 31 are positioned under the division plate 30, and a plurality of dust collecting barrels 50 are provided beneath the filter cylinders 40.
The setting racks 60 are in pair and in parallel provided under the division plate 30, respectively and axially bored with an accommodating groove 61.
The forcing rods 70 corresponding with the setting racks 60 are in pair received in the corresponding accommodating groove 61, and the sections of the focing rods 70 are unequal diameter and formed with a major diameter section 71 and a minor diameter section 72. Further, the forcing rods 70 respectively have one end vertically connected with a rotary handle 73, and the rotary handles 73 corresponding with the forcing rods 70 are provided in pair and can be firmly locked in place by a locking member 80, which is a screw in this preferred embodiment.
The assembling-and-disassembling plates 90 are respectively fixed on the twinned forcing rods 70 and respectively bored with a plurality of openings 91 corresponding with the through holes 31 for the filter cylinders 40 to be respectively inserted therein.
For further understanding the structural features, the use and method of technology and the expected effect to be achieved of this invention, the way of use of this invention is stated as follows:
Referring to
To replace or wash clean the filter cylinders 40, only unscrew the locking member 80 and turn the twinned rotary handles 73 to actuate the forcing rods 70 to rotate, letting the assembling-and-disassembling plate 90 move downward. When the minor diameter sections 72 of the forcing rods 70 are perpendicular to the underside of the assembling-and-disassembling plates 90, as shown in FIG. 8, the assembling-and-disassembling plate 90 assembled thereon with the filter cylinders 40 can be removed out of the housing 10.
Thus, when the filter cylinder 40 are to be assembled in or disassembled from the dust collector 300, the twinned rotary handles 73 are turned to actuate the forcing rods 70 to rotate and force the filter cylinders 40 to tight fit with the division plate 30 by the unequal diameter twin forcing rods 70. By so designing, this invention is able to enhance convenience in assembly and disassembly of filter cylinders, attain good airtight effects and further enhance efficacy of air purification and quality of use of the filter cylinder type dust collector.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
