[0030] The top of the housing 1 is provided with a plurality of insertion holes, and the partition plate 7 is provided with a communication cavity 9 corresponding to each insertion hole one by one and communicating the upper cavity and the lower cavity; a sealing head 10 for sealing the communication cavity 9 is arranged at the communication cavity 9, and a spring member 13 connected to and supporting the sealing head 10 is arranged below the sealing head 10. One end of the filter tube 6 is a liquid inlet end for liquid to enter its interior, and a pressing block 66 is arranged at the liquid inlet end of the filter tube 6; a plurality of filter tubes 6 are provided and are inserted into the respective insertion holes one by one, and the liquid inlet end of the filter tube 6 is butted against the communication cavity 9, and the pressing block 66 at the liquid inlet end presses against the sealing head 10 to force the sealing head 10 to move downward to compress the spring member 13 into a compressed state, and to make the sealing head 10 disengage from the sealing of the communication cavity 9 to make the communication cavity 9 enter a conducting state. At this time, the liquid in the lower cavity can enter the interior of the filter tube 6 through the communication cavity 9 and enter the upper cavity after being filtered by the filter tube 6. When the filter tube 6 is pulled out, the spring member 13 pressed by the filter tube 6 resets, pushing the sealing head 10 to re-seal the corresponding communication cavity 9, so that the communication cavity 9 automatically enters a closed state.

[0031] As can be seen from the above, in the present utility model, the internal space of the housing 1 is divided into an upper cavity and a lower cavity by the partition plate 7, the electrolyte to be filtered is made to enter the lower cavity through the liquid inlet pipe 5, and the filtered electrolyte is conveyed out of the upper cavity through the liquid outlet pipe 4; the communication cavity 9 on the partition plate 7 is used for the upper cavity and the lower cavity, and the sealing head 10 and the spring member 13 cooperate to control the on-off of the communication cavity 9; the liquid inlet end of the filter tube 6 is butted against the communication cavity 9, and the pressing block 66 at the liquid inlet end presses against the sealing head 10 to force the sealing head 10 to move downward to compress the spring member 13 into a compressed state, and to make the sealing head 10 disengage from the sealing of the communication cavity 9 to make the communication cavity 9 enter a conducting state, so that the electrolyte in the lower cavity enters the interior of the filter tube 6 through the communication cavity 9 and enters the upper cavity after being filtered by the filter tube 6, and is discharged through the liquid outlet pipe 4 communicated with the upper cavity. When it is necessary to replace or clean the filter tube 6, only the filter tube 6 needs to be pulled out. At this time, the spring member 13 pressed by the filter tube 6 resets, pushing the sealing head 10 to re-seal the corresponding communication cavity 9, so that the communication cavity 9 enters a closed state, the cleaned or newly replaced filter tube 6 is re-inserted, and the sealing head 10 is pushed downward again, so that the communication cavity 9 enters a conducting state again.
