Description

Novel paint mist filtering box

Technical Field

The utility model relates to a coating cloud strains box technical field, specifically is a novel coating cloud strains box.

Background

The conventional treatment mode is that the overspray paint mist is collected by a paint mist treatment system to become paint slag, and then the paint slag is delivered to a company with special qualification for fixed-time and fixed-point deep burying treatment. The general spray booth of the conventional coating line may be classified into a dry spray booth and a wet spray booth. The primary dry-type spray booth is generally applied to the condition that the requirement on the paint surface is low, or the spray booth occupies a large area due to the fact that the bus body of a large-sized spray product (such as a large bus, a metal wall plate and the like) is large, and the investment cost for establishing a conventional water circulation mode is expensive. Therefore, in a coating line of a bus, paint mist felt is usually arranged in a spray booth to capture over-sprayed paint mist, and the purpose of using the cheap paint mist felt is to save cost. However, this type of spraying is difficult to control the process and the spraying effect is relatively poor. Meanwhile, the raw material of the paint mist felt is glass fiber, and the paint mist felt cannot be degraded even if being incinerated and deeply buried, so that the paint mist felt is seriously not in line with the current environmental protection requirement. Governments in various places are also strictly controlling and auditing the production of paint mist felt. The main material of the paint mist felt is glass fiber, the paint mist felt is easy to break and is easy to absorb human bodies to cause health hidden troubles, and the single-layer material structure is also frequently replaced due to poor adsorption performance. In contrast, the wet spray booth has excellent capture performance for overspray mist, and particularly, the wet spray booth is preferred to be used for spraying car bodies and decorative parts because the design can better control the process quality level. The wet spraying room has the problem of relatively large investment, and the process is to take away paint mist generated in the production process by circulating water and then inject chemical agents into the circulating water to separate the paint mist. This process is a superposition of contamination. The problem that has been faced by each coating line plant is how to handle paint residues, traditionally by deep-burying, which is completely inexplicable. The environmental pollution degree of the people is increasingly serious.
