[0040] Specifically, the two partition plates 41 inside the sub-tank frame 4 divide the sub-tank frame 4 into a transition chamber, a liquid storage chamber, and a connecting chamber.

The filter plate 52 filters the floating substances in the overflowing electrophoresis liquid. The filter element 62 in the filter element 6 connected to the bottom of the side tank frame 5 filters the electrophoresis liquid that has passed through the filter plate 52 again, so that the filter element 62 further cleans the residual substances in the electrophoresis liquid and improves the quality of the filtered electrophoresis liquid.

[0041] Hydraulic mechanism 8 includes a hydraulic pump 81, one end of which is connected to a connecting rod 82. A support rod 42 is fixedly connected to the top of the connecting rod 82, and a cross arm 83 is fixedly connected to the bottom of the connecting rod 82. Support columns 84 are symmetrically fixed to the top of the cross arm 83, and a rack 85 is fixedly fixed to the top of the support columns 84. A gear block 86 meshes with one end of the rack 85. Two gear blocks 86 are connected through a rotating shaft 87, which passes through a protruding frame 11 and is fixedly connected to a limit block 88. One end of the limit block 88 is fixed... A collector block 31 is connected to the nozzle 32. A hose 33 is fixedly connected to one end of the collector block 31, and a nozzle 32 is fixedly connected to the other end of the collector block 31. A baffle 321 is fixedly connected to one end of the nozzle 32. A fixing strip 34 is fixedly connected to the collector block 31 at one end of the fixing strip 34. A flow guide shroud 35 is fixedly connected to one end of the flow guide shroud 35. A movable sleeve 351 is movably provided inside the flow guide shroud 35. A support strip 352 is fixedly connected to one end of the movable sleeve 351. A flow baffle 353 is fixedly connected to one end of the support strip 352. The support strip 352 is located away from the movable sleeve 351. A flow-blocking plate 353 is fixedly connected to one end of sleeve 351, and an annular plate 354 is fixedly connected to one end of flow-blocking plate 353; a hinge 361 is fixedly connected to one end of flow guide shroud 35, and a base 36 is connected to the end of hinge 361 away from flow guide shroud 35; a limiting strip 37 is provided at the bottom end of base 36, and the limiting strip 37 is fixedly connected to the main tank frame 1; slots 362 for liquid extraction are opened at both ends of base 36; the circulation mechanism 7 includes an outer pipe 71, and a diversion pipe 72 is fixedly connected to one end of the outer pipe 71 for diversion. One end of pipe 72 is connected to a diversion valve 73, and the other end of pipe 72 is connected to a diversion valve 75. The top of diversion valve 73 is connected to a pump body 74. One end of diversion valve 73 is connected to a branch pipe 731, the top of diversion valve 73 is connected to a pump body 74, the top of pump body 74 is connected to a branch pipe 741, one end of diversion valve 75 is connected to a branch pipe 751, the top of diversion valve 75 is connected to a pump body 76, and the top of pump body 76 is connected to a branch pipe 761.

[0042] Specifically, in the hydraulic mechanism 8, the hydraulic pump 81 is fixed on the main slot frame 1. The hydraulic pump 81 drives the connecting bar 82 to move in a directional manner. The top end of the connecting bar 82 is fixed to the support rod 42, and its bottom end is fixed to the cross arm 83. When the hydraulic pump 81 drives the connecting bar 82 to move upward, the support rod 42 drives the fixed sealing ring 43 to close the through hole opened in the partition plate 41, so that the transition cavity, the liquid storage cavity and the connecting cavity change from a connected state to a closed single state. The support column 84 fixed to the cross arm 83 drives the sealing ring 43 fixed to its top end to move upward. The rack 85 moves in a directional manner, and the gear block 86 meshing with the rack 85 drives the fixed rotating shaft 87 to rotate along the axis of the gear block 86. The rotating shaft 87 rotates through the limiting block 88 fixed to the protruding strip. The flow collecting block 31 fixed to the limiting block 88 drives the flow guide 35 to rotate synchronously. The base 36 connected to the flow guide 35 through the hinge 361 is limited by the limiting strip 37, so that during the rotation of the flow guide 35, the output end of the flow guide 35 is in contact with the top surface of the base 36, realizing that the flow guide 35 is horizontal from the fixed point 2. When the flow guide 35 switches to the vertical state, the limiting ring 355 inside the flow guide 35 abuts against the base 36, causing the movable sleeve 351 to move directionally along the axis of the flow guide 35. This causes the movable sleeve 351 to move and abut against the baffle 321 fixed to the nozzle 32, so that the nozzle 32, the flow guide 35, and the base 36 form an integral chamber structure. The sediment located at the grooves at both ends of the main trough frame 1 is drawn into the side trough frame 5 through the symmetrical slots 362 on the base 36, and the sediment is filtered through the filter plate 52 and the filter element 62. When the hydraulic pump 81 drives the horizontal arm 83 to reset, the nozzle 32 and the guide shroud 35 rotate to a horizontal state, and the base 36 is separated from the guide shroud 35 by the limit bar 37, so that the output end of the guide shroud 35 is in an open state. The movable sleeve 351 impacts the flow-blocking plate 353 and the limit ring 355 fixed to the support bar 352 through the liquid sprayed from the nozzle 32, so that the movable sleeve 351 is separated from the baffle 321, and the nozzle 32 and the guide shroud 35 are in an open state, which improves the flow of the electrophoresis liquid in the main tank frame 1.The external pipe 71 in the circulation mechanism 7 is used to connect to the external liquid supply equipment. When the fixed part 2 and the circulation part 3 are aligned, the diversion valve 1 73 connects the diversion pipe 72 to the branch pipe 1 731. The branch pipe 1 731 is connected to the hose 33 connected to the manifold 31 in the circulation part 3 through a pipe. The diversion valve 2 75 connects the diversion pipe 72 to the branch pipe 3 751. The branch pipe 3 751 is connected to the connecting pipe 21 in the fixed part 2 through a pipe, and the connecting pipe is connected to multiple nozzles 22, so that the main tank frame 1 can increase the volume of electrophoresis liquid through the external liquid supply equipment and clean the floating substances through the overflow port 12. When the fixed part 2 and the circulation part 3 are not aligned... At the same time, diversion valve 1 73 connects branch pipe 1 731 to pump body 1 74. Branch pipe 2 741 connected to the top of pump body 1 74 connects to the liquid storage chamber through a pipe. Diversion valve 2 75 connects branch pipe 3 751 to pump body 2 76. Branch pipe 4 761 connected to the top of pump body 2 76 connects to the side tank frame 5 through a pipe. Through pump body 2 76 and circulation component 3, the sediment in the main tank frame 1 is pumped into the side tank frame 5 for filtration. Through pump body 1 74, the filtered electrophoretic solution is pumped into the main tank frame 1 through nozzle 22 connected to connecting pipe 21. This achieves self-cleaning of the electrophoretic solution in the main tank frame 1 through circulation, improving the quality of the electrophoretic solution after use.

[0043] Working principle:

[0044] Normal electrophoresis mode: When the circulation mechanism 7 is connected to the external liquid supply equipment, the first diversion valve 73 and the second diversion valve 75 respectively connect the diversion pipe 72 to the first branch pipe 731 and the third branch pipe 751; the electrophoresis liquid passes through the collector block 31 of the circulation component 3 and the connecting pipe 21 of the fixed point component 2, and forms a horizontal jet flow with the nozzle 32 through the nozzle 22, which promotes the uniform flow of the electrophoresis liquid in the main tank frame 1; excess liquid enters the secondary tank frame 4 through the high overflow port 12, and after passing through the three-stage buffer of the transition chamber, the liquid storage chamber and the connecting chamber of the partition plate 41, it flows into the side tank frame 5 through the low overflow port 12; the inclined filter plate 52 intercepts floating impurities to the slag collection bar 51, and the liquid is deeply filtered by the filter element 62 of the filter component 6 and then flows back to the secondary tank frame 4, realizing the continuous removal of floating objects and the circulation and purification of electrophoresis liquid.

[0045] Self-cleaning mode: When it is necessary to remove sediment, the hydraulic mechanism 8 drives the linkage 82 to move upward, causing the sealing ring 43 of the support rod 42 to close the through hole of the partition plate 41, making each chamber of the sub-slot frame 4 independent; at the same time, the cross arm 83 pushes the rack 85 through the support column 84, and drives the rotating shaft 87 through the gear block 86, so that the guide shroud 35 of the circulation component 3 rotates around the hinge 361 to a vertical state; the base 36 fits against the guide shroud 35 under the action of the limiting strip 37, and the movable sleeve 351 is pushed against the baffle 321 by the limiting ring 355 to form a closed chamber; at this time, the circulation mechanism 7 Switching pathways: Diverter valve 1 73 connects pump body 1 74 to the liquid storage chamber, and diverter valve 2 75 connects pump body 2 76 to the side tank frame 5; pump body 2 76 extracts the sediment from the bottom of the groove through the slot 362 of the base 36, and after filtration by the filter plate 52 and filter element 62, it is temporarily stored in the liquid storage chamber; pump body 1 74 pumps the purified liquid into the main tank frame 1 through the nozzle 22 of the fixed part 2 to form an internal circulation cleaning; after completion, the hydraulic mechanism is reset, the guide shroud 35 rotates back to the horizontal state, and the movable sleeve 351 separates from the baffle 321 under the impact of the liquid flow, restoring the open spray state and ensuring the fluidity of the electrophoresis liquid.

[0046] By intelligently switching between two modes, the system achieves efficient removal of floating impurities and sediment during electrophoresis. At the same time, through the synergistic effect of filter element 6 and circulation mechanism 7, the high purity of the electrophoresis solution is maintained for recycling, significantly improving the quality and efficiency of electrophoresis treatment.
