AI Technical Summary

Technical Problem

In the process of preparing high-purity copper powder and polyaluminum chloride in the acid etching waste liquid, the stacking state of aluminum sheets causes some copper powder to adhere to the surface of aluminum sheets, blocking the contact between the aluminum sheets and the waste liquid, affecting the reaction efficiency.

Method used

A device including a support base, reaction assembly and auxiliary mechanism is designed. By stirring and extruding the aluminum sheet by mixing and extruding the aluminum sheet, the aluminum sheet and waste liquid are ensured to be in full contact with the waste liquid, and the filtering assembly is combined to achieve rapid separation of copper powder and solution.

Benefits of technology

The replacement speed of aluminum sheets is improved, the reaction efficiency is enhanced, and the copper powder residue is reduced, and the efficient preparation of high-purity copper powder and polyaluminum chloride is achieved. The process is simple, energy-saving and environmentally friendly.

Abstract

The invention discloses equipment for preparing high-purity copper powder and polyaluminum chloride from acid etching waste liquid and an energy-saving co-production process of the equipment, and relates to the technical field of acid etching waste liquid recycling, the equipment comprises a supporting base, a reaction assembly is arranged at the top of the supporting base, and the reaction assembly comprises a preparation tank body, a sealing cover and a telescopic rod. According to the aluminum sheet extrusion device, the top of the pressing ring can be connected through the telescopic rod and the guide piece, the top of the guide piece is in lap joint with the adjusting block through the contact head, when the cam rotates, the guide rod can be driven to reciprocate on the top of the supporting plate, the guide piece can be driven to ascend and descend through the adjusting block, and therefore the use height of the pressing ring and the use height of the guide disc are adjusted, and aluminum sheets are extruded; the flow of the waste liquid inside and outside the mixing tank can be accelerated, and then the aluminum sheets are stirred through the stirring blades, so that the aluminum sheets fully contact and react with the waste liquid; and the filter screen is arranged in the filter box, copper powder in the waste liquid can be rapidly separated, copper powder residues in the waste liquid are reduced, and follow-up concentrated recovery of the copper powder is facilitated.
