[0026] In this technical solution, through the arrangement of the cross plate 4 and the support spring 5, the pin rod 3 can be guided to prevent the pin rod 3 from tilting during movement, and at the same time, the bottom of the connecting plate 6 can be supported. Moreover, when the connecting plate 6 moves upward, the support spring 5 can generate a pulling force on the connecting plate 6, so that the connecting plate 6 can move downward and reset after the guide frame 20 is separated from the moving frame 7. Through the arrangement of the guide cross bar 29, the purpose of guiding the moving plate 28 is achieved, and the moving plate 28 is prevented from tilting during movement. Through the arrangement of the sealing gasket 26, the sealing performance of the contact between the sealing baffle 21 and the diversion partition 27 is effectively improved. Through the arrangement of the discharge valve 24 and the drain pipe 10, it is convenient for personnel to discharge the electroplating solution that has been filtered inside the filter tank 1. Through the arrangement of the circulation pump 25 and the circulation pipe 12, under the action of the working circulation pump 25, the electroplating solution contained inside the filter tank 1 can be extracted and conveyed upward to the upper cavity of the filter tank 1 through the circulation pipe 12, so as to facilitate the personnel to carry out the circulating filtration operation of the electroplating solution.

[0027] The working principle of the present utility model is as follows: Through the setting of the liquid inlet pipe 11, it is convenient for personnel to add the electroplating solution to be filtered into the interior of the filter box 1. And through the setting of the diversion partition plate 27, after the electroplating solution filled in the interior of the filter box 1 is effectively diverted, the electroplating solution can pass through the filter plate 23 inside the filter frame 2 for effective impurity filtration, and then flow down to the bottom of the filter box 1 for collection, thereby achieving the effect of filtering the electroplating solution, facilitating the subsequent use of the electroplating solution by personnel. And when it is necessary to maintain and replace the filter plate 23, by starting the driving motor 22 to work, the second screw rod 19 can be driven to rotate. The rotation of the second screw rod 19 can drive the moving plate 28 and the sealing baffle 21 to move. Under the action of the movement of the sealing baffle 21, the opening on one side of the diversion partition plate 27 can be blocked, so that the electroplating solution filled in the interior of the filter box 1 can flow and perform the filtration operation from the opening on the other side of the diversion partition plate 27. At the same time, during the movement of the moving plate 28, the guiding frame 20 can be driven to move. Under the action of the movement of the guiding frame 20, it can contact the surface of the moving frame 7, and through the inclined plane, the moving frame 7, the connecting plate 6 and the pin rod 3 can be pushed upward, so that the pin rod 3 can be disengaged from the surface of the pin hole 30 on the locking block 31, thereby being able to release the limit of the filter frame 2. Subsequently, personnel can draw out the filter frame 2 and the filter plate 23 from the interior of the filter box 1, thus facilitating the replacement and maintenance operation of the filter plate 23 by personnel. The overall operation is convenient and fast, effectively ensuring that when the filter plate 23 is maintained and replaced, the filtration work of the electrolyte can still proceed normally, which is beneficial for personnel to use.
