Spraying type pre-air-treatment system

Abstract

The invention discloses a spraying type pre-air-treatment system suitable for cleaning products which are about to be subjected to spraying before treatment. The spraying type pre-air-treatment systemcomprises a spraying room and a plurality of water pump rooms. The spraying room is composed of a spraying compartment. A traction mechanism is arranged on the top wall of the spraying compartment and provided with a traction arm hanging the products. A plurality of spraying agent chambers and a plurality of water dripping air drying chambers are arranged below the traction mechanism and are thesame in number, and the spraying agent chambers and the water dripping air drying chambers are alternately distributed and are in communication. Each spraying agent chamber is provided with an air extractor, and each water dripping air drying chamber is provided with an air blower. The products are driven by the traction arm to move in the spraying agent chambers and the water dripping air dryingchambers, and nozzles are arranged on the peripheries of the spraying agent chambers. The water pump rooms correspond to the spraying agent chambers in a one-to-one manner, and the water pump rooms provide a liquid agent spraying function for the nozzles. Since each spraying agent chamber is provided with one water dripping air drying chamber and one water pump room corresponding to the spraying agent chamber, after the products are cleaned in one spraying agent chamber and before the products enter the next spraying agent chamber, the products need to be subjected to residual liquid agent removal treatment through the corresponding water dripping air drying chambers, and it is guaranteed that the situation of liquid agent playing is avoided; and the liquid agent can be cyclically utilized, the integral design structure is compact, closing performance is good, and operation is simple and convenient.

Description

technical field [0001] The invention relates to a pre-treatment device for cleaning products before spraying, in particular to a spray-type pre-air treatment system 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 t...

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
