Processing device before spraying

Abstract

A processing device before spraying comprises an alkali washing pool (1), a water washing pool (2), an acid washing pool (3), two A clear water pools (4), a B clear water pool (5), a chromizing pool (6), a C clear water pool (7), a D clear water pool (8), a water draining zone (9) and a drying furnace (10), wherein each of the above pools has a rectangular case shape, all the pools are sequentially and tightly arranged side by side, the water draining zone (9) is closely near to the D clear water pool (8), the drying furnace (10) is closely near to the water draining zone (9), two end portions of the part of each of the pools having a distance of 20cm to the upper opening are respectively and correspondingly provided with two overflow apertures, the end of each of the pools close to the bottom is provided with a blowing tube and a blowing valve, each blowing tube is connected with a collecting tube (11), the upper openings of the alkali washing pool (1), the acid washing pool (3) and the chromizing pool (6) are respectively provided with an air pump, the front ends of the air pumps reach the bottoms of the three pools (1,3,6), and the collecting tube (11) is connected to a water processing pool.

Description

technical field [0001] The invention relates to a treatment device before spraying. Background technique [0002] The acid etching and degreasing process of aluminum alloy surface treatment combines the traditional process of degreasing, alkali etching, and decontamination and degreasing into one process to reduce costs and save energy. The treated aluminum alloy surface is smooth and clean, maintaining the aluminum The original luster of the alloy, less aluminum dissolution loss and bath precipitation, good matching performance with chromate conversion treatment, especially suitable for surface treatment of aluminum alloy profiles before spraying. In long-term production and application, the treatment process of aluminum alloy surface before spraying is relatively simple, and the treatment device used for acid etching and degreasing before aluminum spraying and improving the finish is usually to build several large pools with cement in the workshop, although this This meth...

AI Technical Summary

Problems solved by technology

For example: 1. The pool is large in size and occupies the space of the workshop; 2. The pool mouth is open, and it is easy for workshop dust and other debris to fall into the pool, which affects the treatment effect; 3. The pool body is high, inconvenient for workers to operate, and there are potential safety hazards; 4. , The amount of clean water injected each time is relatively large. Once it becomes industrial wastewater, it will be discharged in large quantities and cause pollution to the environment. It is a waste of water and cannot be recycled.
