[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This embodiment provides a technical solution: an automatic cleaning and filtration device for electrode foil electrolytic cells of high-capacity aluminum electrolytic capacitors, including a filter chamber 1, a filter plate 6 inside the filter chamber 1, the filter plate 6 being a plate structure with uniformly distributed filter holes at the upper end, mounting plates 5 being fixedly connected to the left and right ends of the inner wall of the filter chamber 1, each mounting plate 5 having a positioning hole inside, positioning posts being fixedly connected to the left and right ends of the lower surface of the filter plate 6, the positioning posts being tightly inserted into the vertically adjacent positioning holes, a drive chamber 3 being provided at the left end of the filter chamber 1, a controller 12 being provided at the front end of the left side surface of the drive chamber 3, the input end of the controller 12 being electrically connected to an external power supply, and a cleaning mechanism 4;

[0024] Cleaning mechanism 4 includes a chute 44, a sliding seat 45, and a cleaning roller 46. The chute 44 is symmetrically arranged on the inner walls of the left and right sides of the filter chamber 1. The sliding seat 45 is slidably connected inside the chute 44. A cleaning roller 46 is rotatably connected between two adjacent sliding seats 45 (the outer surface of the cleaning roller 46 is provided with a brush, which can make close contact with the outer surface of the filter plate 6). The cleaning roller 46 is installed in conjunction with the outer surface of the filter plate 6. A rubber sealing sleeve 13 is provided between the chute 44 and the adjacent sliding seat 45 (the rubber sealing sleeve 13 expands and contracts during the movement of the sliding seat 45 to prevent liquid from entering). (Entering the drive unit affects the service life of the drive components). The cleaning mechanism 4 also includes a rotating shaft 42, a drive pulley 43, and a gear 47. The rotating shaft 42 is rotatably connected to the front and rear ends inside the drive chamber 3. The middle of the rear rotating shaft 42 is fixedly connected to the drive pulley 43, and the middle of the front rotating shaft 42 is fixedly connected to the driven pulley. The driven pulley and the drive pulley 43 are connected by a transmission belt. The left ends of the two sliding seats 45 on the left side are fixedly connected to the corresponding ends of the transmission belt. The upper and lower ends of the inner wall of the drive chamber 3 are fixedly connected to rack plates, and the left ends of the cleaning rollers 46 are fixedly connected to gears 47. The upper gear 47 meshes with the upper rack plate, and the lower gear 47 meshes with the lower rack plate. The cleaning mechanism 4 also includes a motor 41, which is located at the rear end of the left side surface of the drive chamber 3. The right end of the output shaft of the motor 41 is fixedly connected to the left end of the rear rotating shaft 42. The input end of the motor 41 is electrically connected to the output end of the controller 12. The controller 12 enables the motor 41 to operate. The rotation of the output shaft of the motor 41 drives the rear rotating shaft 42 to rotate, which in turn drives the drive pulley 43 to rotate. The drive pulley 43 drives the driven pulley to rotate through the transmission belt. The rotation of the transmission belt drives the upper sliding seat 4. 5 moves backward, simultaneously driving the lower sliding seat 45 to move forward, thereby enabling the upper cleaning roller 46 to move backward and the lower cleaning roller 46 to move forward. During the movement of the cleaning roller 46, due to the meshing of the gear 47 and the rack plate, the gear 47 rotates. The rotation of the gear 47 drives the adjacent cleaning roller 46 to rotate. The rotation of the cleaning roller 46 achieves cleaning and scraping of the upper and lower surfaces of the filter plate 6, while breaking up impurities. This allows the impurities to fall into the bottom of the filter chamber 1 along with the water through the filter cylinder of the filter plate 6. Then, the controller 12 opens the electric valve 11 in the middle of the waste liquid pipe 8, and the cleaning waste liquid is removed through the waste liquid pipe 8.

[0025] The filter chamber 1 is connected to a top 2 via evenly distributed bolts. A supply pipe 7 is installed at the top of the top 2, with its upper end connected to the outlet of an external cleaning liquid tank and a water pipe in an external water tank. A nozzle is installed at the lower end of the supply pipe 7. An outlet pipe 9 is installed at the front end of the lower surface of the filter chamber 1, and a waste liquid pipe 8 is installed at the rear end. An inlet pipe 10 is installed in the middle of the front surface of the top 2. Electric valves 11 are installed in the middle of the waste liquid pipe 8, outlet pipe 9, and inlet pipe 10. The input ends of the three electric valves 11 are electrically connected to the output end of a controller 12. The controller 12 controls the operation of the electric valves 11 in the middle of the inlet pipe 10, allowing the electrolyte to enter the filter chamber 1 through the inlet pipe 10. The filter plate 6 filters the electrolyte, and the filtered impurities adhere to the surface of the filter plate 6. At the same time, the controller 12 opens the electric valve 11 in the middle of the outlet pipe 9, and the filtered electrolyte is removed through the outlet pipe 9. When cleaning is required, the controller 12 closes the electric valve 11 in the middle of the inlet pipe 10 and the electric valve 11 in the middle of the outlet pipe 9. The external cleaning liquid tank supplies cleaning liquid into the supply pipe 7, and then sprays it onto the outer surface of the filter plate 6 through the nozzle. After cleaning is completed, the personnel close the electric valve 11 in the middle of the waste liquid pipe 8 through the controller 12 and stop the water supply from the external water tank. At the same time, the electric valve 11 in the middle of the inlet pipe 10 and the electric valve 11 in the middle of the outlet pipe 9 are opened to continue the electrolyte filtration.

[0026] The working principle of the automatic cleaning and filtration device for the electrode foil electrolytic cell of the high-capacity aluminum electrolytic capacitor provided by this utility model is as follows: During operation, the operator first stably places the filter chamber 1, the chamber top 2, and other mechanisms in a horizontal working area. After stable placement, the operator uses the controller 12 to operate the electric valve 11 in the middle of the inlet pipe 10. The electrolyte enters the interior of the filter chamber 1 through the inlet pipe 10, and the filter plate 6 filters the electrolyte. The filtered impurities adhere to the surface of the filter plate 6. Simultaneously, the controller 12 operates the electric valve 11 in the middle of the outlet pipe 9. Electric valve 11 opens, and the filtered electrolyte flows out through outlet pipe 9. When cleaning is required, controller 12 closes electric valve 11 in the middle of inlet pipe 10 and electric valve 11 in the middle of outlet pipe 9. The external cleaning liquid tank supplies cleaning liquid into the supply pipe 7, and then sprays it onto the outer surface of filter plate 6 through nozzles. After spraying, personnel stop the supply of liquid from the external cleaning liquid tank and supply liquid to the supply pipe 7 from the external water tank, and then spray it out through nozzles. At the same time, controller 12 starts motor 41, and the output shaft of motor 41 rotates to drive the rear side The rotating shaft 42 rotates, which in turn drives the drive pulley 43 to rotate. The drive pulley 43 drives the driven pulley to rotate via the transmission belt. The rotation of the transmission belt causes the upper sliding seat 45 to move backward, and at the same time, it causes the lower sliding seat 45 to move forward. This causes the upper cleaning roller 46 to move backward and the lower cleaning roller 46 to move forward. During the movement of the cleaning roller 46, due to the meshing of the gear 47 and the rack plate, the gear 47 rotates. The rotation of the gear 47 drives the horizontally adjacent cleaning roller 46 to rotate. The system automatically cleans and scrapes the upper and lower surfaces of the filter plate 6, breaking down impurities so that they fall into the bottom of the filter chamber 1 along with the water through the filter cartridge of the filter plate 6. Then, the controller 12 opens the electric valve 11 in the middle of the waste liquid pipe 8, allowing the cleaned waste liquid to be removed through the waste liquid pipe 8. After cleaning is completed, the personnel close the electric valve 11 in the middle of the waste liquid pipe 8 through the controller 12 and stop the water supply from the external water tank. At the same time, the electric valve 11 in the middle of the inlet pipe 10 and the electric valve 11 in the middle of the outlet pipe 9 are opened to continue the filtration of the electrolyte.

[0027] It is worth noting that the controller 12 disclosed in the above embodiments controls the operation of the motor 41 and the electric valve 12 using methods commonly used in the prior art.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
