A shelf-type paint mist separation device and method for separating overspray

Abstract

The invention relates to a shelf-type paint mist separation device and a dry Venturi paint spraying system applied thereto. The paint mist separation device has a split structure, and the shell is made of hard and durable materials, which can be recycled. A shelf is arranged inside the shell. A variety of disposable paint mist separation components are arranged on each shelf from bottom to top. The housing is provided with a door for replacing the disposable paint mist separating part. The air inlet is set at the lower part of the paint mist separation device, and the air outlet is set at the top of the paint mist separation device. The air and the overspray carried by it enter the paint from the air inlet in an obliquely downward direction through the Venturi channel of the Venturi painting system. The mist separation device then turns to move upward, and the main flow direction of the air passes through the paint mist separation device from bottom to top. During the process, the overspray is separated by the paint mist separation component arranged in the paint mist separation device. Compared with the prior art, the invention has good paint mist separation effect and less consumption of disposable separation materials.

Description

technical field [0001] The invention relates to the field of industrial coating, especially to the field of separation and collection of sprayed overspray, specifically a shelf-type paint mist separation device and a method for separating overspray, which are widely used in automobiles, hardware, home appliances, toys, etc. painting. Background technique [0002] With the rapid development of China's economy, environmental pollution has become more and more serious. In most parts of our country, human pollution of air, soil and water has far exceeded the capacity of nature. In recent years, smog has occurred frequently, and water pollution and soil pollution have become more and more serious. Painting is a highly polluting and energy-intensive industry. During the coating production process, a large amount of exhaust gas, waste liquid and solid waste will be generated. In order to maintain the constant temperature and humidity conditions required for painting, a large am...

AI Technical Summary

Problems solved by technology

Different temperature and humidity conditions and different spraying parameters will also cause differences in the characteristics of oversprayed particles. In the process of spraying construction, the temperature and humidity may fluctuate at any time, the type of paint needs to be replaced, and the spraying parameters sometimes need to be adjusted. The particle characteristics of the sprayed matter are always changing, which increases the difficulty of matching the type of the paint mist separation box with the one-off overall structure with the overspray, the ability of the paint mist separation box to capture and accommodate the overspray and It is difficult to achieve the best separation effect

[0007] In addition, the paint mist separation box of this structure uses disposable separation materials to intercept the adhered overspray, and the consumption of disposable separation materials is large
