The swing rod 303 is provided with an elongated hole 304, and the push shaft 302 is slidably connected to the elongated hole 304. The rotating sleeve 307 is rotatably connected to the bottom of the filter box 101. The second gear 306 is fixed on the rotating sleeve 307 and meshes with the sector tooth 305. The rotating sleeve 307 and the rotating shaft 108 are connected by a one-way transmission assembly 4. The one-way transmission assembly 4 drives the rotating shaft 108 to rotate by the reciprocating rotation of the rotating sleeve 307.

[0048] In this embodiment of the invention, the transmission shaft 203 drives the rotating disk 301 to rotate, the rotating disk 301 drives the push shaft 302 to revolve, the push shaft 302 drives the swing rod 303 to swing through the elongated hole 304, the swing rod 303 drives the second gear 306 to reciprocate through the sector tooth 305, and the second gear 306 drives the rotating sleeve 307 to reciprocate.

The first release assembly 7 intermittently releases the meshing of the second meshing tooth 603 and the inner ratchet ring 503 by intermittently rotating the rotating shaft 108.

[0052] In this embodiment of the invention, the meshing component 6 drives the second meshing tooth 603 to mesh with the inner ratchet ring 503, thereby keeping the connecting rod 502 stationary. The connecting rod 502 drives the piston block 111 to remain stationary. The rotating shaft 108 drives the rotating block 109 to rotate. The rotating block 109 moves relative to the piston block 111, thereby compressing the second spring 501. Until the rotating shaft 108 finishes rotating, the first release component 7 intermittently releases the meshing of the meshing component 6 with the second meshing tooth 603 and the inner ratchet ring 503 by intermittently rotating the rotating shaft 108.

The side wall of the push block 704 is provided with an installation groove 706. The two ends of the pull rope 701 are respectively connected to the installation groove 706 and the second slider 602. The retaining component 8 is disposed on the piston block 111, and the retaining component 8 is used to temporarily restrict the push block 704 from extending out of the connecting rod 502.

[0056] In this embodiment of the invention, when the push block 704 contacts the rotating block 109, the rotating block 109 overcomes the elastic force of the fourth spring 705 and pushes the push block 704 into the connecting rod 502. At this time, the push block 704 pushes the third slider 703, the third slider 703 pulls the pull rope 701, the pull rope 701 overcomes the elastic force of the third spring 604 and pulls the second slider 602 to move in the opposite direction.

[0058] In this embodiment of the invention, the fifth spring 806 pushes the fourth slider 802, and the fourth slider 802 drives the insertion rod 803 to be inserted into the slot 804.

[0059] like Figure 3 and Figure 9As shown, in a preferred embodiment of the present invention, the second release component 9 includes a sliding rod 901, a steering wheel 902, and a connecting rope 903.

[0062] S1. Connect the inlet pipe 102 to the electrolyte delivery pipe, connect the outlet pipe 105 to the collection box, and inject electrolyte into the filter box 101 through the inlet pipe 102.

[0063] S2. The filter cartridge 103 filters the electrolyte through the filter screen 104. The filtered electrolyte enters the filter cartridge 103 and is discharged from the drain pipe 105.

[0064] S3. The rotating component 2 drives the rotating ring 106 to rotate, the rotating ring 106 drives the rotating plate 107 to rotate, the rotating plate 107 drives the electrolyte to move, and the electrolyte generates centrifugal force and throws the impurities to the vicinity of the side wall of the filter box 101.

[0065] S4. The transmission mechanism 3 drives the rotating shaft 108 to rotate intermittently through the rotating component 2. The reciprocating moving component 5 drives the piston block 111 to reciprocate within the cavity 110 by rotating the rotating block 109 intermittently.

The rotating plate 107 causes the electrolyte to move, generating centrifugal force and throwing away impurities. The filter moves to the vicinity of the side wall of the filter box 101, thus preventing impurities from being re-adsorbed onto the filter screen 104. The drive shaft 203 drives the rotating disk 301 to rotate, and the rotating disk 301 drives the push shaft 302 to revolve. The push shaft 302 drives the swing rod 303 to swing through the elongated hole 304. The swing rod 303 drives the second gear 306 to reciprocate through the sector teeth 305. The second gear 306 drives the rotating sleeve 307 to reciprocate. The first spring 405 pushes the first slider 403 to move. The first slider 403 drives the first meshing tooth 404 to mesh with the ratchet 401, thereby causing the rotating sleeve 307 to drive the ratchet 401. The ratchet 401 drives the rotating shaft 108 to rotate intermittently. When the rotating shaft 108 rotates, the third spring 604 pushes the second slider 602. The second slider 602 drives the second meshing tooth 603 to mesh with the inner ratchet ring 503, thereby keeping the connecting rod 502 stationary. The connecting rod 502 drives the piston block 111 to remain stationary, and the rotating shaft 108 drives the rotating block 109 to rotate. The rotating block 109 moves relative to the piston block 111, thereby compressing the second spring 501. At the same time, the filtered electrolyte enters the cavity 110 through the one-way valve and the inlet 113. When the push block 704 contacts the rotating block 109, the rotating block 109 overcomes the elastic force of the fourth spring 705 and pushes the push block 704 into the connecting rod 502. At this time, the push block 704 pushes the third slider 703, the third slider 703 pulls the pull rope 701, and the pull rope 701 overcomes the elastic force of the third spring 604 and pulls the second slider. When slider 602 moves in the reverse direction, the second slider 602 causes the second meshing tooth 603 to disengage from the inner ratchet ring 503. Simultaneously, the fifth spring 806 pushes the fourth slider 802, which in turn causes the insertion rod 803 to insert into the slot 804, restricting the movement of the third slider 703. At this time, the second spring 501 pushes the piston block 111 to move in the reverse direction. The piston block 111 discharges the filtered electrolyte through a one-way valve and pressurizes it out of the flushing port 112. The high-pressure electrolyte discharged from the flushing port 112 flushes the filter screen 104, thereby cleaning the impurities clogging the filter screen 104. When the second spring 501 pushes the piston block 111 to move, the piston block 111 drives the sliding rod 901 to move until the sliding rod 901 contacts the inner wall of the cavity 110.At this time, the sliding rod 901 moves into the fourth slide groove 801, pulling the connecting rope 903. The connecting rope 903 pulls the fourth slider 802, which in turn causes the insertion rod 803 to disengage from the slot 804. The fourth spring 705 pushes the third slider 703 and the push block 704 back to their original positions. The third spring 604 pushes the second slider 602 and the second meshing tooth 603 back to their original positions. This completes one work cycle. The filter screen 104 is cleaned by the continuous intermittent rotation of the rotating shaft 108.
