Description

CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims the benefit and priority of Chinese Patent Application No. 202311072379.2, filed with the China National Intellectual Property Administration on Aug. 24, 2023, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.

TECHNICAL FIELD

The present disclosure relates to the technical field of dosing and stirring devices, and in particular to an intelligent control-based dosing and stirring device for sediment pollution control.

BACKGROUND

The level of pollution of channel reservoirs in cities is increasing day by day, mainly due to the leachate generated by garbage accumulation around the reservoir, the leakage of domestic sewage from sewage pipes around the reservoir, and the initial rainwater flowing into the reservoir water. When the input of pollutants exceeds the self-purification ability of the reservoir, some pollutants are deposited at the bottom of the reservoir, which leads to the secondary release of pollutants from the sediment and the repeated deterioration of water quality. The existing the main methods for sediment treatment are in-situ treatment and ex-situ treatment. In-situ treatment technology is to treat sludge in situ. The in-situ treatment technology can avoid the high cost of sludge transfer and secondary pollution and the loss of reservoir sediment by treating the sediment in situ. The existing in-situ treatment technology is mainly to add sediment-improving chemicals to the sediment, which are used to remove reducing substances in the water by oxidation, and degrade or absorb nitrogen, phosphorus and other elements, thus solving the problem of sediment pollution.

Before adding the improving chemicals into the reservoir, the chemicals need to be formulated, so it is necessary to use a dosing and stirring device for sediment pollution control to proportion the chemicals and add the proportioned chemicals into the reservoir. When the existing dosing and stirring device is used, the chemicals are stirred and mixed by the rotation of the stirring blade. However, the chemical cartridge for carrying the chemicals is usually only placed on the support frame, and the cartridge may shake when the chemicals are stirred and driven to rotate. Generally, such shaking is avoided by the weight of the chemical cartridge and the chemicals, but the greater the amount of the chemicals, the greater the force generated by the rotation, which cannot fundamentally solve the generation of shaking. In addition, the existing stirring blade is fixed to the rotating shaft by a bolt, and if the stirring blade needs to be replaced, the operation is more troublesome.

Moreover, the clamping operation for the chemical cartridge 3 is convenient, the chemical cartridges 3 with different sizes can be fixed, and the convenience during the use of the device is improved.

A second embodiment is shown in FIG. 2 and FIG. 3, the main difference from the first embodiment is that the shock-absorbing assembly 6 includes multiple arc-shaped grooves 61 formed in an inner surface of the support ring 11 at equal distance. Multiple connecting blocks 62 are fixedly connected to an annular surface of the circular support block 51 at equal distance, and the multiple connecting blocks 62 are in sliding connection with the arc-shaped grooves 61 at corresponding positions, respectively.

Both ends of the buffer spring 64 are in contact with the inner wall of the arc-shaped groove 61 and a side surface of the connecting block 62, respectively.

The shock-absorbing assembly 6 is arranged at the periphery of the circular support block 51 to absorb the force generated by stirring the chemicals, thus avoiding the problem of position deviation of the whole supporting underframe 2 caused by excessive force.

A third embodiment is shown in FIG. 6 to FIG. 9, the main difference from the second embodiment is that a stirring assembly 4 includes an input motor, a rotating shaft 7, and a stirring blade. The stirring blade is mounted on the rotating shaft 7 by a mounting assembly 8. The mounting assembly 8 includes a mounting groove 81 formed in a bottom end of the rotating shaft 7, and a mounting rod 82. A groove 83 is formed in a top end of the mounting rod 82, a circular plate 84 is in sliding connection with an inner surface of the groove 83, a first reset spring 85 is fixedly connected to the bottom of the circular plate 84, and the other end of the first reset spring 85 is fixedly connected to the bottom of the inner wall of the groove 83. A limiting groove is formed in each of a front face and a back face of the mounting rod 82. A limiting post in fit with the limiting groove is arranged on each of a front face and a back face of an inner wall of the mounting groove 81, and a clamping groove is formed in a top edge of the circular plate 84. A left L-shaped rod 88 and a right L-shaped rod 88 are in sliding connection with left and right sides of the rotating shaft 7 by chutes, respectively. A downward bent end of each of the two L-shaped rods 88 extends into the mounting groove 81, and the other end of the two L-shaped rods 88 is fixedly connected to a shifting ring 89. A second reset spring 810 is fixedly connected between the bottom of the L-shaped rod 88 and the bottom of an inner wall of the chute.

The stirring blade is mounted on the rotating shaft 7 by the mounting assembly 8. When the mounting assembly 8 is used to mount the stirring blade, the stirring blade can be simply and rapidly mounted only by pressing and rotating once.

During mounting, the chemical cartridge 3 is placed at the top of the circular support block 51, the drive motor 57 is started to drive the driving gear 58 to rotate, the driving gear 58 rotates, and the rotation of the driving gear 58 is transmitted to the annular gear 56. The annular gear 56 rotates, and the rotation of the annular gear 56 is transmitted to the transmission gear 55. The transmission gear 55 rotates to make the rack 54 move, the rack 54 moves to drive the cambered plate 59 to move close to the outside of the chemical cartridge 3 and clamp the outside of the chemical cartridge 3. At this time, the mounting of the chemical cartridge 3 is completed. When the stirring assembly 4 works to stir chemicals in the chemical cartridge 3, a generated force is first transmitted to the circular support block 51, the circular support block 51 generates a shake tendency which is transmitted to the connecting block 62, such that the buffer spring 64 is compressed, and the damper 63 is used for shock absorption and absorbing the transmitted force. In addition, during the mounting of the stirring blade, the stirring blade is sleeved at the bottom end of the rotating shaft 7, and the mounting rod 82 is mounted in the mounting groove 82, and the mounting rod 82 moves towards the inside of the mounting groove 81. The limiting post 87 enters a vertical portion of the limiting groove 86, and after the limiting post 87 reaches the bottom, the mounting rod 82 is rotated to make the limiting post 87 enter an inclined portion of the limiting groove 86, such that the mounting rod 82 can move upwards to press against the stirring blade. In addition, when the limiting post 87 enters the end of the inclined portion of the limiting groove 86, the limiting post 87 enters the clamping groove 811 on the circular plate 84, thereby limiting the whole mounting rod 82 and preventing rotation. When disassembling, the shifting ring 89 is rotated downwards to make the L-shaped rod 88 in contact with the circular plate 84, such that the clamping groove 811 is separated from the limiting post 87. At this time, the mounting rod 82 can be rotated and pulled out, thus completing the disassembling of the stirring blade.
