Split powder spray gun sprayer

Abstract

The invention belongs to the technical field of spray gun accessories, and relates to a powder spray gun sprayer, in particular to a split nonmetal powder spray gun sprayer. According to the adopted technical scheme, the split powder spray gun sprayer comprises shells and powder supply pipelines arranged inside the shells; the shells comprise the shell A and the shell B; the powder supply pipelines comprise the powder supply pipeline A and the powder supply pipeline B; the shell A is arranged outside the powder supply pipeline A, the shell B is arranged outside the powder supply pipeline B, the shell A and the shell B are detachably connected, and the powder supply pipeline A and the powder supply pipeline B are detachably connected; a plurality of discharge sets are arranged at the front end of the powder supply pipeline B in the length direction of the powder supply pipeline B; and each discharge set comprises a plurality of discharge outlets formed in the circumferential direction of the powder supply pipeline B. The split powder spray gun sprayer has the advantages that the structure is reasonable, discharging is uniform, the discharging direction is controllable, the middle of the sprayer is in a threaded connection mode so that disassembly and assembly can be convenient, operation is convenient, the use effect is good, the use cost can be easily reduced, and resources are saved.

Description

technical field [0001] The invention relates to a powder spray gun nozzle, in particular to a split type non-metallic powder spray gun nozzle, which belongs to the technical field of spray gun accessories. Background technique [0002] At present, in the anti-corrosion field of oil pipeline inner coating, powder coating has the tendency to gradually replace liquid coating due to its excellent characteristics such as environmental protection, safety, and less volatile gas, especially the demand for powder coating in oil pipelines is increasing. The powder inner coating of petroleum pipelines generally adopts hot-melt spraying, that is, the powder spray gun is inserted into the pipe body, and the powder is sprayed into the high-temperature pipeline. The powder melts at high temperature and adheres to the inner wall of the pipe. The nozzles of the existing powder spray guns are all integrated, which is not only inconvenient to disassemble and assemble, but also needs to be repl...

AI Technical Summary

Problems solved by technology

The nozzles of the existing powder spray guns are all integrated, which is not only inconvenient to disassemble and assemble, but also needs to be replaced as a whole once damaged, which leads to high cost of use and serious waste of resources, which cannot meet the needs of use
