AI Technical Summary

Technical Problem

Traditional thermal spraying equipment suffers from problems such as powder splashing, environmental pollution, insufficient coating uniformity, and low powder recovery efficiency during the spraying process, which affect coating quality and production efficiency.

Method used

The system employs a closed spraying protection box and a negative pressure recovery system, combined with a servo motor-driven clamping structure and air supply cooling device, to ensure that the spraying process is completed in a closed space. It also efficiently recovers scattered powder through a negative pressure recovery air pump, achieving uniform coating thickness and secondary utilization of materials.

Benefits of technology

It effectively prevents powder splashing, reduces material waste and environmental pollution, improves spraying efficiency and coating uniformity, and reduces production costs.

Abstract

This utility model relates to the field of spraying device technology and discloses an aluminum-silicon wear-resistant coating spraying device, including a spraying protective box. A powder feeder is fixedly installed on the top of the spraying protective box, and a powder feeding pipe is fixedly connected to the output end of the powder feeder. A thermal spray gun is fixedly connected to the end of the powder feeding pipe. A lower protective chamber is fixedly installed on the bottom surface inside the spraying protective box, and an upper protective chamber, which works in conjunction with the lower protective chamber, is movably installed inside the spraying protective box above the lower protective chamber. In this utility model, the spraying device adopts a closed structure of the lower and upper protective chambers, ensuring that the spraying process is completed in a sealed space, effectively preventing aluminum-silicon powder from splashing and reducing material waste. At the same time, through a recovery system consisting of a negative pressure recovery air pump, a first collection pipe, and a second collection pipe, the scattered powder can be efficiently recovered to the collection box, realizing the secondary use of powder, reducing production costs, and reducing environmental pollution.
