Spray-type preprocessing equipment

Abstract

The invention discloses a spray type pretreatment equipment, which is suitable for cleaning products to be sprayed before treatment, and includes a spray room and several water pump rooms. There is a traction mechanism on the wall, and the traction mechanism has a traction arm for hanging products. There are several spray chambers and drip air-drying chambers of the same number under the traction mechanism. These spray chambers and drip air-dry chambers are alternately distributed and connected. There is an air extractor on the spray chamber, and a blower is installed on each drip drying chamber. The product moves in the spray chamber and the drip drying chamber under the drive of the traction arm. There are nozzles around the spray chamber; the water pump room In one-to-one correspondence with the spray chamber, the water pump room provides the nozzle with the function of spraying liquid medicine. Since each spraying chamber has a drip drying room and a water pump room corresponding to it, after the product is cleaned in one spraying room, it needs to be removed by the dripping drying room before entering the next spraying room. The treatment of residual liquid medicine ensures that there is no leakage of liquid medicine, and the liquid medicine can be recycled. The overall design structure is compact, the airtightness is good, and the operation is easy.

Description

technical field [0001] The invention relates to a pre-treatment device for cleaning products before spraying, in particular to a spray type pre-treatment device which can recycle the treatment liquid and has no leakage or channeling of the liquid. Background technique [0002] With the high-speed development of social economy and the further acceleration of industrialization, the surface treatment of products is very important in metal processing and manufacturing industries. During the storage, transportation or processing of workpieces in the factory, foreign matter such as oil stains, rust layers (or oxide scales), dust, etc. will be formed on the surface of the workpieces. If the product mounted on the workpiece with these foreign objects is directly processed, it will not only affect the adhesion, appearance, moisture resistance and corrosion resistance of the product surface, but also rust will spread under the coating film, resulting in peeling and blistering of the c...

AI Technical Summary

Problems solved by technology

[0004] 1. The liquid medicine cannot form an impact on the product, so it cannot be in good contact with the product

[0005] 2. When the product is transferred from one liquid medicine pool to another liquid medicine pool, the liquid medicine in the previous liquid medicine pool will be brought into the next liquid medicine pool, causing unnecessary chemical reactions and causing harm to the product

[0006] 3. The entire equipment is bulky, occupies a large area, is expensive, is not conducive to operation, and has poor airtightness, which is easy to cause leakage of liquid medicine and waste gas, etc., causing harm to the environment
