[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-Figure 6 An electrolyte circulation filtering device shown includes:

[0028] A box body 1, an electrolytic cell 11 is provided on the box body 1, a filter box 12 matched with the electrolytic cell 11 is installed in the box body 1, and the filter box 12 is used to circulate and filter the electrolytic cell 11, a detachable filter plate 13 is installed in the filter box 12, and a movable cleaning plate 14 is provided on the filter box 12 to match it with the filter plate 13; wherein, the structures and principles of the filter box 12, the movable cleaning plate 14 and the filter plate 13 are all prior arts, and specific reference is made to the comparative document (publication number CN214881879U, and the patent name is a circulating filtering device for electrolyte in copper foil production), which will not be repeated here;

[0029] The cleaning assembly 2 is used to adjust the spacing between the filter box 12 and the movable cleaning plate 14. The cleaning assembly 2 includes a slot 23 provided on the filter box 12 and the movable cleaning plate 14, and a movable cavity 21 provided on one side of the filter box 12 for the movable cleaning plate 14 to slide into. The movable cavity 21 is communicated with the interior of the slot 23. A closing plate 22 for closing the movable cavity 21 is inserted into the slot 23. The outside of the filter box 12 is sleeved with an installation box 24, and the installation box 24 is located above the slot 23. A connecting assembly 3 for connecting the installation box 24 with the closing plate 22 is provided. A soft pad is also fixed to the side of the closing plate 22 adjacent to the telescopic column 44, and one side of the soft pad is in contact with the inside of the slot 23.

[0030] The connecting component 3 includes an installation cavity 37 opened on one side of the installation box 24 and a connecting rod 31 fixed on the top of the closing plate 22, and the top of the connecting rod 31 passes through the installation cavity 37 and is fixed with a connecting tube 32, and a driving component for driving the connecting tube 32 to move is provided in the installation cavity 37; the driving component includes a rack 33 fixed on the outer wall of the connecting tube 32 and a driving motor 34 fixed in the installation cavity 37, a rotating rod 36 is fixed at one end of the driving motor 34, a gear 35 is sleeved on the outside of the rotating rod 36, and the gear 35 is meshed with the rack 33; a box door for closing the installation cavity 37 is also hinged on one side of the installation box 24, a guide groove is opened in the installation cavity 37, a guide block corresponding to the guide groove is fixed on the outside of the connecting tube 32, and the guide block is slidably connected to the guide groove.

[0031] As can be seen from the above, when the electrolyte in the electrolytic cell 11 enters the filter box 12, the electrolyte is filtered by the filter plate 13, and then the impurities carried in the electrolyte are filtered and processed, and the electrolyte is reused after being filtered, so the electrolyte in the electrolytic cell 11 can be circulated and filtered for reuse;

[0032] When it is necessary to clean the impurities attached to the filter plate 13 regularly, the driving motor 34 drives the rotating rod 36 to rotate, and then the rotating rod 36 rotates to drive the gear 35 to rotate. At this time, the gear 35 is engaged with the rack 33, and the rack 33 moves upward along the installation cavity 37. The movement of the rack 33 drives the connecting cylinder 32 to move upward, and the movement of the connecting cylinder 32 drives the guide block to slide upward along the guide groove. As the connecting cylinder 32 moves, the connecting rod 31 moves upward, and then the connecting rod 31 moves to pull the closing plate 22 to move along the slot 23, and then the closing plate 22 is separated from the slot 23 opened on the movable cleaning plate 14, so that The movable cleaning plate 14 loses its limiting effect in the movable cavity 21, and the closing plate 22 is kept at a distance from the movable cleaning plate 14 during continuous movement, which can reduce the contact between them, and the movable cleaning plate 14 slides along the movable cavity 21, and then the movement of the movable cleaning plate 14 drives the filter plate 13 to slide along the filter box 12 and the movable cavity 21, so that the filter plate 13 is taken out and cleaned, and then the distance between the movable cavity 21 and the filter plate 13 can be adjusted, which can prevent the filter plate 13 from contacting the filter box 12 when being pulled out, and prevent impurities from falling into the filter box 12, so as to improve the filtering effect of the filtering device on the electrolyte.

[0033] In addition, refer to Figure 2 , Figure 5 and Figure 6As shown, the closing plate 22 is provided with a connecting component 4 for contacting it with the movable cleaning plate 14, and the connecting component 4 includes a plug plate 41 installed on one side of the closing plate 22 and a pin slot 45 opened at the top of the movable cleaning plate 14 for the plug plate 41 to be inserted, and the closing plate 22 is provided with an elastic component for pushing the plug plate 41 to move; the elastic component includes a spring 43 and a telescopic column 44 fixed between the closing plate 22 and the plug plate 41, and a slide groove 42 opened on the top wall inside the movable cavity 21, and the slide groove 42 is slidably connected with the plug plate 41, and the spring 43 is sleeved on the outside of the telescopic column 44.

[0034] Through the above technical solution:

[0035] When the closing plate 22 is inserted into the slot 23, the closing plate 22 moves downward to drive the plug plate 41 to move along the slide groove 42, and then the locking and restoring thrust of the spring 43 makes the plug plate 41 contact with the slide groove 42, and the bottom of the plug plate 41 slides out of the slide groove 42 and moves toward the latch groove 45. At this time, after the closing plate 22 is engaged with the slot 23 opened on the movable cleaning plate 14, the bottom of the plug plate 41 is inserted into the latch groove 45, and the top of the movable cleaning plate 14 contacts with the slide groove 42, thereby achieving a firm connection between the closing plate 22 and the movable cleaning plate 14, thereby preventing the movable cleaning plate 14 from sliding, ensuring that the movable cleaning plate 14 is firmly maintained in the desired position, and further ensuring the normal use of the movable cleaning plate 14.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
