Aluminum material and aluminum product polishing waste acid recycling treatment system and treatment method

Abstract

The invention relates to aluminum material and aluminum product polishing waste acid recycling treatment system and treatment method, wherein the aluminum material and aluminum product polishing wasteacid recycling treatment system comprises an outer frame, a storage device, a pressing device, a stirring device, two stirring devices, two sealing groups and two extrusion blocks; the storage deviceis installed at the upper end of the outer frame, and the pressing device is installed at the lower end of the storage device; a stirring device is installed at the lower end of the pressing device,two stirring devices are arranged at the left and right ends of the stirring device, two sealing sets are arranged at the lower end of the outer frame, and two extrusion blocks are arranged at the front and rear ends of the inner wall of the outer frame. The invention solves the problems that pure water is generally flushed into a waste acid solution from the upper side, so that the pure water initially entering the waste acid solution is not uniformly distributed, fusion can be performed for a long time even after later stirring treatment, and a traditional stirring paddle difficultly stirs the waste acid solution at the bottom of a frame body, and the dilution of each position is not uniform due to non-uniform stirring of the stirred waste acid solution.

Description

technical field [0001] The invention relates to the technical field of processing aluminum materials and aluminum products, in particular to a treatment system and method for recycling waste acid from polishing aluminum materials and aluminum products. Background technique [0002] The purpose of polishing aluminum and aluminum products is to improve the surface smoothness, smoothness and decorative effect of the product, and to enhance the corrosion resistance of aluminum. According to the polishing process, it can be divided into chemical polishing and electrolytic polishing. Due to the low cost and simple process of chemical polishing, chemical polishing is mainly used for polishing aluminum profiles at present. After chemical polishing, waste acid solutions will be produced, and these waste acid solutions can often be recycled after treatment. [0003] In the process of treating the waste acid solution, it needs to be diluted. The traditional dilution method usually pour...

AI Technical Summary

Problems solved by technology

[0006] The present invention can solve the problem that since pure water is usually poured into the waste acid solution from above, the distribution of the pure water that first enters into the waste acid solution is uneven, and it takes a long time to fuse even after the stirring treatment in the later stage. However, it is difficult for the traditional stirring paddle to stir the waste acid solution at the bottom of the frame, which makes it difficult for the stirred waste acid solution to have uneven dilution at each position due to uneven stirring.
