Spray booth for automatically recycling spray mist through electrostatic adsorption

Abstract

The invention relates to a spray booth for automatically recycling spray mist through electrostatic adsorption, in particular to a spray booth for automatically recycling and treating spray mist generated during spraying operation. The spray booth comprises an electrostatic spray gun, a paint bucket providing paint to the spray gun, an air compressor providing high-pressure air and an enclosure which is provided with a workpiece fixing device and provides operation space for spraying. The enclosure comprises four operation chambers, including a spray chamber, an electrostatic chamber and a fan chamber which run through each other in sequence along the spraying direction, and a recycle chamber which is positioned below the electrostatic chamber and runs through the electrostatic chamber. The operators in the spray booth need to be equipped with masks and inflated protective clothing so that the operators can not breathe the toxic gases in the spray booth and can not have occupational diseases. The spray booth solves the problem that the existing machines have low spraying efficiency, even spraying but high price, low manual spraying cost, flexible operation but heavy labor intensity, poor operation conditions, etc, and has the characteristics of spray mist reduction and environmental protection, reduction of damage to the bodies of the operators and the environment, reduction of waste of paint resources, simple operation, high efficiency, etc.

Description

1. Technical field [0001] The invention relates to a spray booth, in particular to a spray booth which automatically recovers and processes paint mist generated during spraying. 2. Background technology [0002] There are two types of spraying, one is manual spraying and the other is machine spraying. If machine spraying adopts electrostatic spraying method, it has the advantages of high efficiency, less waste, good quality, and is beneficial to the health of workers. However, electrostatic spraying must be automatically run on an assembly line, otherwise the person holding the workpiece will also be sprayed with paint, and the assembly line The cost of equipment is high, and machine spraying is generally only suitable for regular workpieces, and the application range is relatively small. Therefore, most domestic manufacturers still use manual spraying. [0003] Artificial spraying is a dangerous job, because the paint is relatively volatile and toxic. During the painting p...

Problems solved by technology

If machine spraying adopts electrostatic spraying method, it has the advantages of high efficiency, less waste, good quality, and is beneficial to the health of workers. However, electrostatic spraying must be automatically run on an assembly line, otherwise the person holding the workpiece will also be sprayed with paint, and the assembly line The cost of equipment is high, and machine spraying is generally only suitable for regular workpieces, and the application range is relatively small. Therefore, most domestic manufacturers still use manual spraying

[0003] Artificial spraying is a dangerous job, because the paint is relatively volatile and toxic. During the painting process, a large amount of paint mist will be generated in the spraying room. This mist not only loses a large amount of paint resources, about 30% to 50%. The paint is wasted in the air; at the same time, it also seriously pollutes the working environment and seriously affects the health of workers

[0004] At present, there are several methods to deal with paint mist, such as water curtain type (Chinese Patent No. 200420105892.3 paint spray booth paint mist removal device), dry filter type (Chinese Patent No. Changing water causes waste of water resources, or inability to recycle paint conveniently causes secondary pollution to the environment, or the filter screen tends to be saturated with paint mist particles and needs to be taken out and cleaned frequently, so it cannot achieve a good paint mist removal and recovery effect.
