Abstract

The invention provides a piece of powder coating equipment which comprises a spraying gun part, wherein the spraying gun part comprises a powder outlet which is disposed in a conical manner; an impeller is installed in the powder outlet; a powder circulation gap is disposed between the impeller and the powder outlet; a mixing chamber is disposed on the upper part of the impeller and installed at the powder outlet; the mixing chamber is located above the back face of the impeller and disposed in an annular manner; and the mixing chamber comprises a chamber wall, a channel communicating with the mixing chamber is formed in the chamber wall, and a power supply pipeline is connected to the channel. According to the invention, the high-voltage powder chamber is used as a powder supply source; a powder floating rate is increased by 15%-20%; and centrifugal effects generated from impeller rotation are used to solve the uniformity problem existing in powder fluidization.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a spraying equipment, in particular to a powder coating equipment and a coating process. Background technique [0002] At present, the powder coating equipment adopts the Venturi powder pump conveying and spraying method, and the compressed air drives the powder to achieve high-speed conveying to complete the spraying. The powder jet obtained in this way presents the characteristics of high speed, high air content and low powder density. [0003] The high-speed jet leads to serious rebound of powder particles, and the powder feeding rate is low; the low powder density makes it difficult to improve the spraying efficiency, especially in the case of long-distance spraying, and the high air content creates great pressure on the dust collection and recovery system, resulting in The dust removal system has high power and large volume, and powder spillage is unavoidable, w...
