Spray-type preprocessing equipment

Abstract

The present invention discloses a spray-type preprocessing device, which is suitable for cleaning the product before being sprayed, and comprises a spray house and a plurality of pumping houses, wherein, the spray house consists of spray chambers, and the tops of the spray chambers are provided with traction mechanisms provided with traction arms for hanging products; a plurality of spray powder chambers and drip drying chambers of same numbers are arranged below the traction mechanisms, the spray powder chambers and the drip drying chambers distribute in an alternate way and communicate with each other, each spray powder chamber is provided with an spray powder chamber and each drip drying chamber is equipped with a blower, the products are tracted by the traction arms moving in the the spray powder chambers and the drip drying chambers ,and nozzles are arranged around the spray powder chambers; the pumping houses and the spray powder chambers are in a one to one relationship, and the pumping houses provide the function of spraying liquid medicine for the nozzles. As each spray powder chamber is matched with one drip drying chamber and one pumping house, after being cleaned in one spray powder chamber and before entering the next spray powder chamber, the products need to be treated with a residual liquor removing process in the drip drying chamber, thus ensuring that the liquid medicines are not mixed and are able to be recycled. The present invention has compact structure of the whole design, excellent sealing ability and easy operation.

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
