Direct discharge will seriously pollute the environment and waste copper resources. In view of the shortage of copper resources in my country, it is particularly important to recycle the copper in the etching waste liquid to reduce pollution and save resources.

[0003] For example, the Chinese patent with the publication number CN218756045U discloses an acid etching solution copper recovery and regeneration device, including a base, a group of support columns are fixedly installed on the left and right parts of the lower end of the base, the two groups of support columns are symmetrically distributed and each group is set to two, a stirring assembly is fixedly installed on the left part of the upper end of the base, a group of pillars are fixedly installed on the right part of the upper end and the middle part of the upper end of the base, the two groups of pillars are symmetrically distributed and each group is set to two, a cross plate is fixedly installed on the upper ends of the two groups of pillars, a recovery assembly is fixedly installed on the middle part of the upper end of the cross plate, and a filter box is fixedly installed on the right part of the upper end of the base. The acid etching solution copper recovery and regeneration device described in the utility model, by setting a stirring assembly, first injects the acid etching solution and additives into the mixing barrel from the injection pipe, and the rotating column is driven by the motor, the connecting plate is driven by the rotating column, and the stirring frame is driven by the connecting plate, so that the additives and the acid etching solution are easy to mix and process.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: if the above device does not fully filter the acid etching solution, impurities may react with copper ions when the additives are mixed with the acid etching solution to form difficult-to-separate compounds, reducing the copper extraction efficiency. At the same time, the filter frame of the above device may be damaged after long-term use, and the filter frame needs to be disassembled and replaced. The device is not convenient for cleaning or replacing the filter. In view of this, we propose an acid etching solution copper recovery and regeneration device. Utility Model Content

The pump 21 is powered on to draw the acid etching liquid in the filter box 4 into the feed pipe 22 through the discharge pipe 20, and then into the mixing tank 1 through the feed pipe 22. Then, the additive is poured into the mixing tank 1 through the feed pipe 18, and then the motor 13 is started. The motor 13 is powered on to drive the rotating column 2 and the plurality of stirring blades 3 to rotate, so that the acid etching liquid and the additive in the mixing tank 1 can be mixed. When the mixing is completed, the discharge pipe 19 is opened. The valve on the mixing tank 1 is opened, and the acid etching liquid mixed in the mixing tank 1 enters the filter box 4 through the discharge pipe 19, and then the mixed acid etching liquid enters the top of the filter screen 7 for filtration, and the copper will be filtered and left on the top of the filter screen 7, and the liquid enters the bottom of the inner cavity of the filter box 4 through the filter screen 7. Under the action of the rotation of the filter screen 7, the copper can be better filtered, and the copper will not block the filter screen 7. Finally, the valve on the discharge pipe 3 23 is opened to discharge the filtered liquid from the filter box 4;

[0081] When the filter screen 7 needs to be replaced, the connecting rod 25 is first pulled in the direction of the spring 2 16, and the connecting rod 25 drives the two sliding blocks 17 to slide in the direction of the spring 2 16, and at the same time, the plurality of springs 2 16 are squeezed and contracted. When the two sliding blocks 17 enter the two sliding grooves 2 15 respectively, the sliding rod 11 is pulled in the direction of the spring 12, and at the same time, the spring 12 is squeezed and contracted. When one side of the sliding rod 11 is separated from the rotating frame 6, the handle 24 is pulled upward, and the handle 24 drives the sealing plate 26 to slide upward. When the sealing plate 26 is completely taken out, the rotating frame 6 can be taken out. , then put the new rotating frame 6 into the filter box 4, and then insert the sealing plate 26 into the filter box 4. The personnel loosen the sliding rod 11. Under the action of the rebound force of the spring 12, the spring 12 drives the sliding rod 11 to slide and insert into the rotating frame 6, which can limit the position of the rotating frame 6. Finally, loosen the connecting rod 25. Under the action of the rebound force of the plurality of springs 16, the plurality of springs 16 respectively drive the two sliding blocks 17 to slide, and then the two sliding blocks 17 can fix the position of the sealing plate 26, so that the sealing plate 26 will not move, thereby achieving the purpose of facilitating the replacement of the filter screen 7.
