Problems solved by technology

[0002] At present, the particle size distribution curve of the main mill powder particles in the existing powder coating mills is relatively wide, scattered, and not concentrated, and the particle size of the separated powder particles is too small, resulting in the particle size of the separated powder particles being less than 10 microns. The powder content is high, which seriously affects the quality of the finished powder and reduces the powder rate of the product

Abstract

The invention belongs to the technical field of powder coating classifying equipment and relates to powder particle classifying equipment, in particular to a separator capable of controlling particle size distribution in a high-precision mode. The separator capable of controlling the particle size distribution in the high-precision mode comprises a discharge hopper, a separation chamber, a classification chamber and a feed pipe, and is characterized in that a gap allowing tiny air flow to pass is formed in the connection portion of the discharge hopper and the separation chamber, the periphery of the gap is provided with a pneumatic control assembly communicated with an external air source, and the pneumatic control assembly comprises a pneumatic pipeline, a control valve and an air flow buffer air chamber, wherein the pneumatic pipeline is connected to the gap in the tangent direction, and the air flow buffer air chamber surrounds the gap. The separator greatly increases the controllability over particle size distribution, is high in separation accuracy, increases the content of powder with the particle size smaller than 10 micrometers in the powder, and further improves product quality and the powdering rate.

Description

technical field [0001] The invention relates to a powder particle classification equipment, in particular to a high-precision separator for controlling particle size distribution, and belongs to the technical field of powder coating classification equipment. Background technique [0002] At present, the particle size distribution curve of the main mill powder particles in the existing powder coating mills is relatively wide, scattered, and not concentrated, and the particle size of the separated powder particles is too small, resulting in the particle size of the separated powder particles being less than 10 microns. The powder content is higher, which seriously affects the quality of the finished powder and reduces the powder rate of the product. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art, provide a scientific and reasonable structure design, effectively reduce the proportion of pow...
