Spiral-flow type spraying structure and spray gun thereof

Abstract

The invention provides a spiral-flow type spraying structure and a spray gun thereof. The spiral-flow type spraying structure comprises a body; the body is internally provided with high-pressure waterflow channels and a mixing cavity; the high-pressure water channel is provided with a high-pressure water nozzle at the bottom of the mixing cavity; the body is provided with a jet flow outlet communicated with the inside and outside of the mixing cavity at the opposite side of the bottom of the mixing cavity; a plurality of the high-pressure water flow channels are arranged on the same circumference; and the plurality of high-pressure water flow channels are obliquely arranged to force a plurality of high-pressure water flows to be sprayed into the mixing chamber in a spiral shape and form flexible eddy currents in the mixing chamber. The jet flow sprayed by the spiral-flow type spraying structure provided by the invention acts on an object to be hit at a certain tangential angle, and continuously rubs on the surface of a workpiece for a certain distance before leaving the surface of the workpiece, thus increasing the effective working time of the jet flow and having high efficiency;and the jet flow is favorable for forming mist-like jet flow after being sprayed out, and the working effect is more uniform when used for polishing, cleaning or polishing the workpiece.

Description

technical field [0001] The invention relates to the surface treatment industry, in particular to a swirl spray structure and a spray gun thereof. Background technique [0002] The mixed jet spray gun can be used for cleaning, derusting, polishing, and removing dirt on the surface of objects. Such as rust removal on the surface of steel plates, treatment of various casting surface attachments, cleaning of various types of ground, polishing treatment on the surface of work pieces, etc. [0003] The traditional spray gun nozzle usually adopts the form of single nozzle or multi-nozzle direct injection. After the jet is sprayed out, it only pops up immediately after point-to-point strike, and the work efficiency is low. [0004] In addition, when abrasives are mixed, there are problems of low mixing and acceleration efficiency. Ordinary nozzles such as sand mixing nozzles, after high-pressure water is sprayed out, mix with abrasives in a limited mixing chamber, which only bring...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a swirling jet structure to solve the technical problems in the prior art that the jet only pops up immediately after point-to-point hitting and the work efficiency is low.

[0006] At the same time, another object of the present invention is to provide a spray gun with the above-mentioned swirl spray structure, so as to solve the technical problems in the prior art that the jet only pops up immediately after point-to-point strike, and the work efficiency is low.
