Description

Technical Field

[0001] The utility model relates to the technical field of recovery devices, in particular to a recovery device for acid etching liquid which is easy to clean. Background Art

[0002] Etching liquid is a raw material for copperplate engraving. It is a liquid that is engraved by corroding the material's characteristics. After the acidic etching liquid is used, it needs to be recycled to prevent its waste liquid from being directly discharged and causing pollution. Therefore, it is necessary to use this kind of easy-to-clean acidic etching liquid recovery device. Since the etching liquid wastewater contains a large amount of copper ions, the waste liquid needs to be electrolyzed during the terminal treatment of the acidic etching liquid wastewater to extract the copper ions in the waste liquid, and the electrolytic clear liquid obtained after electrolysis is directly neutralized and discharged.

[0003] There are many types of such recovery devices on the market today, which can basically meet people's needs, but there are still certain problems: when traditional recovery devices of this type are used, they often lack anti-corrosion treatment on the inner wall of the device. When the acid etching liquid is recovered for a long time, the inner wall of the device is corroded, which will reduce its service life to a certain extent, and the residual liquid on the inner wall of the device cannot be cleaned. For this reason, we propose an easy-to-clean acid etching liquid recovery device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an easy-to-clean recovery device for acid etching liquid, which can increase the reaction rate of the liquid, improve the corrosion resistance of the device body to a certain extent, improve the sealing of the device, and is convenient to recycle and easy to clean. It has high practicality and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an easy-to-clean acid etching solution recovery device comprises a reaction barrel and a barrel cover;

[0009] Starting the drive motor can drive the stirring shaft to rotate, and the rotation of the stirring shaft can drive the spiral stirring blade to rotate, so that the acid etching solution in the reaction barrel can fully contact and react with the positive and negative electrodes of the electrolyte sheet assembly, thereby facilitating the improvement of the reaction rate.

[0012] Furthermore, the spray assembly includes an annular guide pipe, a connecting pipe, a spray head, a water supply pipe and a fixed piston.

A plurality of evenly distributed spray heads are fixedly arranged on the lower side of the two annular guide pipes. The left and right sides of the annular guide pipes are connected to the water supply pipe. The outer sides of the two water supply pipes pass through the reaction barrel and are connected to the fixed piston.

[0013] Open the fixed piston and connect the water supply pipe with the external water supply port, so that the clean water can be diverted to the two annular guide pipes. The clean water is then distributed to any position of the two annular guide pipes through the connecting pipe, and finally sprayed out by the sprinkler head, so that the inside of the reaction barrel can be cleaned. The inner side of the connecting pipe is rotatably connected to the outer side of the stirring shaft, so that the rotation of the stirring shaft will not affect the work of the annular guide pipe, which is convenient for cleaning.
