After a long period of filtering, the inside of the filter hole on the filter plate will be blocked. At this time, the No. 2 motor is started to drive the turntable to rotate, thereby driving the convex rod to move circumferentially. Since the cross rod sleeved on the convex rod is guided and limited by the guide sleeve, the convex rod will drive the cross rod to move back and forth continuously, thereby driving the piston to move back and forth in the piston cylinder. Since the medium allowed by the one-way valve flows toward the inner cavity of the piston cylinder, and the liquid hole is located on the left side of the air hole, when the piston moves to the left, the external air comes into the piston cylinder for replenishment. When the piston moves to the right and crosses the liquid hole, positive pressure will be formed in the piston cylinder, and the compressed air will be ejected from the filter hole on the filter plate in the opposite direction through the filter cartridge, thereby dredging the inside of the filter hole on the filter plate, thereby circulating to prevent the filter hole from being blocked.

The water end and the drainage end are connected to the alkali liquid tank 2 and the high-level tank 11 through pipes respectively. A cavity plate 12 connected to the high-level tank 11 is fixedly installed on the left side of the top of the filter cartridge 4. The bottom of the cavity plate 12 is provided with linearly distributed drainage holes. The drainage holes at the bottom of the cavity plate 12 are located above the left side of the filter plate 5.

A U-shaped rod 15 is rotatably installed in the vibrator 14, and the rotational power of the U-shaped rod 15 comes from the No. 1 motor in the vibrator 14.

An impact plate 17 is hingedly installed at the bottom of the sleeve rod 16, and the bottom of the impact plate 17 is in contact with the support plate 13.

[0025] Through the above design, after the alkali liquid with impurities in the alkali liquid tank 2 is discharged into the high-level box 11 through the pipeline by the water pump 10, since the cavity plate 12 is connected with the high-level box 11, the alkali liquid in the high-level box 11 will drip into the top left side of the filter plate 5 in multiple streams through the drainage holes linearly distributed at the bottom of the cavity plate 12, and flow to the right side of the filter plate 5 under the influence of its own weight. During the flow, the alkali liquid will pass through the filter holes on the filter plate 5 and come to the inner cavity of the filter cylinder 4 to gather, while the impurities in the alkali liquid are blocked at the periphery of the filter holes. In this process, the No. 1 motor in the vibrator 14 is turned on to drive the U-shaped rod 15 to rotate, and then drive the sleeve rod 16 to make circumferential movement, and then drive the impact plate 17 at the bottom to continuously impact the support plate 13 up and down to produce shaking. At this time, the support plate 13 will transmit the vibration to the filter plate 5, which will accelerate the alkali liquid to pass through the filter holes on the one hand, and on the other hand, shake off the impurities blocked at the periphery of the filter holes and gather on the slag receiving trough 9 for collection.

[0027] Through the above design, when the filtered alkali liquid gathers in the filter cartridge 4, the alkali liquid comes from the inner cavity of the filter cartridge 4 to the inner cavity of the piston cylinder 18, and is discharged into the alkali liquid tank 2 for collection through the pipe connected under the liquid hole 25. After a long period of filtering, the inside of the filter hole on the filter plate 5 will be blocked. At this time, the No. 2 motor is started to drive the turntable 20 to rotate, and then drive the convex rod 23 to move circumferentially. Since the cross rod 22 sleeved on the convex rod 23 is guided and limited by the guide sleeve 21, the convex rod 23 will drive the cross rod 22 to move back and forth continuously. This in turn drives the piston 24 to move back and forth left and right in the piston cylinder 18. Since the medium allowed by the one-way valve 27 flows toward the inner cavity of the piston cylinder 18, and the liquid hole 25 is located on the left side of the air hole 26, when the piston 24 moves to the left, the external air enters the piston cylinder 18 for replenishment. When the piston 24 moves to the right and passes over the liquid hole 25, a positive pressure is formed in the piston cylinder 18, and the compressed air is ejected in the opposite direction from the filter holes on the filter plate 5 through the filter cartridge 4, thereby clearing the inside of the filter holes on the filter plate 5, and the filter holes are prevented from being blocked by this cycle.

[0028] The implementation principle of the embodiment of the present application is:

[0029] First, when the alkali liquid with impurities in the alkali liquid tank 2 is discharged into the high-level box 11 through the pipeline by the water pump 10, since the cavity plate 12 is connected with the high-level box 11, the alkali liquid in the high-level box 11 will drip into the top left side of the filter plate 5 in multiple streams through the drainage holes linearly distributed at the bottom of the cavity plate 12, and flow to the right side of the filter plate 5 under the influence of its own weight. During the flow, the alkali liquid will pass through the filter holes on the filter plate 5 and come to the inner cavity of the filter cylinder 4 to gather, while the impurities in the alkali liquid are blocked at the periphery of the filter holes. In this process, the No. 1 motor in the vibrator 14 is turned on to drive the U-shaped rod 15 to rotate, and then drive the sleeve rod 16 to make circumferential motion, and then drive the impact plate 17 at the bottom to continuously impact the support plate 13 up and down to produce shaking. At this time, the support plate 13 will transmit the vibration to the filter plate 5, which will accelerate the alkali liquid to pass through the filter holes on the one hand, and on the other hand, shake off the impurities blocked at the periphery of the filter holes and gather them on the slag receiving trough 9.

[0030] Furthermore, when the filtered alkali liquid gathers in the filter cartridge 4, the alkali liquid comes from the inner cavity of the filter cartridge 4 to the inner cavity of the piston cylinder 18, and is discharged into the alkali liquid tank 2 through the pipe connected under the liquid hole 25 for collection. After a long period of filtering, the filter holes on the filter plate 5 will be blocked. At this time, the second motor is started to drive the turntable 20 to rotate, thereby driving the convex rod 23 to move circumferentially. Since the cross rod 22 sleeved on the convex rod 23 is guided and limited by the guide sleeve 21, the convex rod 23 will drive the cross rod 22 to move back and forth continuously, thereby The piston 24 is driven to move back and forth left and right in the piston cylinder 18. Since the medium allowed by the one-way valve 27 flows toward the inner cavity of the piston cylinder 18, and the liquid hole 25 is located on the left side of the air hole 26, when the piston 24 moves to the left, the external air enters the piston cylinder 18 for replenishment. When the piston 24 moves to the right and passes over the liquid hole 25, a positive pressure is formed in the piston cylinder 18, and the compressed air is reversely ejected from the filter holes on the filter plate 5 through the filter cartridge 4, thereby clearing the inside of the filter holes on the filter plate 5, and the filter holes are prevented from being blocked by this cycle.

[0031] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
