The suction device 8 will absorb the slag layer by negative pressure, so as to suck the slag layer on the surface of the electrolyte into the slag salvaging box 3. When the absorption operation is completed, the slag gathering assembly drives the slag blocking filter plate 11 to gather the electrolytic slag sucked by the suction device 8 and collects it into the slag receiving cavity 301. When the electrolytic slag enters the slag receiving cavity 301, the liquid returning assembly drives the pressing plate 13 to press the gathered and collected electrolytic slag, so as to return the residual electrolyte in the salvaged electrolytic slag into the electrolytic tank 1 for electrolyte return operation. Compared with the traditional slag salvaging process, the phenomenon of cleaning too much electrolyte is avoided. By the arrangement of the slag gathering assembly and the liquid returning assembly, the electrolyte salvaged during the salvaging can be returned, the waste of electrolyte is reduced, the electrolyte can be better salvaged, and the electrolyte can be better salvaged.

[0036] Working principle: when the slag layer on the surface of the electrolyte in the electrolytic tank 1 needs to be salvaged, the slag ladle 3 is moved to the slag layer on the surface of the electrolyte, and then the suction device 8 is controlled to perform the suction operation on the slag layer. The suction device 8 absorbs the slag layer through negative pressure, so that the slag layer on the surface of the electrolyte is sucked into the slag ladle 3. When the absorption operation is completed, the slag gathering assembly drives the slag blocking filter plate 11 to gather the electrolytic slag sucked by the suction device 8 and collects the electrolytic slag into the slag receiving cavity 301. When the electrolytic slag enters the slag receiving cavity 301, the liquid returning assembly drives the pressing plate 13 to press the gathered electrolytic slag, so that the residual electrolyte in the salvaged electrolytic slag is returned to the electrolytic tank 1 to perform the electrolyte returning operation. Compared with the traditional slag salvaging process, the slag gathering assembly and the liquid returning assembly can return the electrolyte during the salvaging process, reduce the waste of electrolyte, and better perform the electrolyte salvaging operation. When the slag layer needs to be extracted and salvaged, the two shaft rods 1101 are pushed to rotate at the bottom of the vertical plate 1102, so that the two slag blocking filter plates 11 are relatively rotated and closed. When one end of the two slag blocking filter plates 11 is in contact, the two shaft rods 1101 are stopped from rotating, and the two slag blocking filter plates 11 form a complete filter plate at the bottom of the suction device 8. Then, the suction device 8 is driven to extract the slag layer. The suction device 8 moves the electrolytic slag on the slag layer to the slag blocking filter plate 11, and finally the electrolytic slag is blocked at the bottom of the slag blocking filter plate 11, which plays a role in blocking the electrolytic slag and prepares for the subsequent gathering and collection of the electrolytic slag. When the two slag blocking filter plates 11 are combined and placed under the suction device 8, the driving motor 7 drives the arc-shaped blocking plate 701 to rotate through the rotating rod 702, and the arc-shaped blocking plate 701 moves to the bottom side of the slag blocking filter plate 11 through rotation. When one end of the arc-shaped blocking plate 701 is attached to the bottom side of the slag blocking filter plate 11, the slag blocking filter plate 11 and the electrolytic tank box 1 are in a through state, which can provide a suction path for the suction device 8 to extract the slag layer, and can also block the slag receiving cavity 301 to prevent the electrolytic slag in the slag receiving cavity 301 from being extracted by the suction device 8 during the extraction operation; When the motor 7 drives the arc-shaped blocking plate 701 to rotate through the rotating rod 702, one end of the arc-shaped blocking plate 701 moves from one side of the diamond block 10 to the bottom of the slag blocking filter plate 11, and the arc-shaped blocking plate 701 and the diamond block 10 are in a through state. When the electrolytic slag is completely extracted into the slag ladle 3, the motor 7 drives the arc-shaped blocking plate 701 to rotate and reset, and the arc-shaped blocking plate 701 returns to between the diamond block 10 and the slag ladle 3, forming a complete closed plate with the diamond block 10, preventing the extracted electrolytic slag from falling back into the electrolytic tank box 1 after the extraction is completed, and cooperating with the arc-shaped blocking plate 701 to perform the closing operation. When it is necessary to push the two slag blocking filter plates 11 to rotate and close, the push position rod 12 is moved to drive the gear rod 1202 to move through the gear meshing arrangement. When the gear rod 1202 moves, the gear rod 1202 pushes the gear 1103 to rotate, thereby driving the slag blocking filter plate 11 to rotate through the shaft 1101. The two slag blocking filter plates 11 are closed, and vice versa, which drives the two slag blocking filter plates 11 to rotate and close and open. When the push position rod 12 moves, the push position rod 12 pushes the reset spring 601 to slide on the limited slip rod 602. When the suction device 8 completely extracts the electrolytic slag into the slag ladle 3, the motor 7 drives the arc-shaped blocking plate 701 to reset between the slag ladle 3 and the diamond block 10. At this time, the push position rod 12 is stopped, the reset spring 601 pushes the push position rod 12 to reset, the push position rod 12 drives the gear 1103 to rotate through the gear rod 1202, the shaft 1101 drives the slag blocking filter plate 11 to rotate, and one end of the slag blocking filter plate 11 slides on the outer wall of the rotating rod 702 and the diamond block 10, thereby pushing the electrolytic slag extracted by the suction device 8 to rotate and reset, and finally pushing it into the slag receiving cavity 301, which resets the slag blocking filter plate 11 to push the electrolytic slag to collect. When it is needed to push the two slag blocking filter plates 11 to rotate and close, the control hydraulic rod 9 drives the extrusion block 1201 to move up through the support plate 901, the extrusion block 1201 moves up to push and drive the push position rod 12 to move, the push position rod 12 extrudes and moves the reset spring 601 on the limited slip rod 602, the push position rod 12 drives the gear 1103 to rotate through the gear rod 1202, so that the two slag blocking filter plates 11 rotate, and the rotation of the slag blocking filter plates 11 is powered. When it is needed to drive the slag blocking filter plates 11 to rotate and reset, the driving hydraulic rod 9 drives the extrusion block 1201 to move down through the support plate 901, the extrusion block 1201 loses contact with the push position rod 12, the reset spring 601 pushes the push position rod 12 to reset, the gear 1103 drives the slag blocking filter plates 11 to rotate and reset through the shaft rod 1101, then the driving hydraulic rod 9 continues to drive the support plate 901 to move down, the support plate 901 drives the extrusion plate 13 to move through the pressure spring 1301, the extrusion plate 13 scrapes the bottom of the slag blocking filter plates 11, so that the electrolytic slag and electrolyte on the bottom of the slag blocking filter plates 11 are scraped into the slag containing cavity 301, and finally the electrolytic slag and electrolyte are extruded to flow back into the electrolytic tank box 1, the electrolytic liquid is returned, the electrolytic liquid is extruded, and the electrolytic liquid is returned. When the electrolytic tank box 1 is used for electrolysis, the visual recognizer 4 scans the electrolysis in the electrolytic tank box 1 through the camera 401, converts the slag layer shape information on the zinc liquid surface into an image signal through machine vision technology, determines the distribution and thickness of the slag layer through an image processing system, and identifies the position of the slag layer through a visual recognition system, so that the slag layer can be extracted and cleaned by the slag bucket 3, and the position of the slag layer is determined through visual recognition. When the visual recognizer 4 identifies and determines the slag layer cleaning position, the corresponding electric sliding block 201 is driven to move in the guide rail 202, the electric sliding block 201 drives the slag bucket 3 at the corresponding position of the slag layer to move, when the slag bucket 3 is placed above the slag layer, the electric telescopic rod 5 is controlled to drive the slag bucket 3 to move down, the slag bucket 3 moves to the top of the slag layer, the electric telescopic rod 5 and the electric sliding block 201 cooperate with each other, so that the slag bucket 3 moves, and the slag bucket 3 is aligned with the slag layer.
