Abstract

The invention provides an injection device for surface treatment or coloring. The injection device comprises a nozzle body, and the nozzle body is internally provided with a liquid channel, a gas channel and a temperature regulating gas channel; the liquid channel is located at the center position of the nozzle body, and the gas channel is located on the radial outer side of the liquid channel; the temperature regulating gas channel is located on the radial outer side of the gas channel, and the liquid channel comprises a first diameter part (1), a second diameter part (2), a first tapered part (3), a diffusion cavity (5) and an outlet part (6); the injection device is characterized in that the inner peripheral surface of the first tapered part is provided with a plurality of swirl plates(41) uniformly distributed in the circumferential direction; and the radial inner edges of the swirl plates are provided with a plurality of swirl slots (42) distributed in the axial direction of theswirl plates. According to the injection device, the rotational kinetic energy/tangential speed of fluid can be increased, and the mixing effect of the fluid is improved; the injection device has theadvantages of a pressurization effect, uniform atomization of the nozzle, small size of droplets, and an excellent injection/atomization effect; the temperature regulating gas flow direction is controllable and accurate, and the flow is stable; and the subsequent drying time is shortened.

Description

technical field [0001] The invention relates to the technical field of surface treatment, such as surface coloring, painting, coating, atomization, etc., and specifically relates to a spraying device for surface treatment or coloring. Background technique [0002] In the field of surface treatment technology, different surface treatment methods (spraying) are usually adopted according to the different / requirements of the treated objects, such as surface coloring, painting, coating, atomization, etc. However, the existing spraying device has the problems of poor mixing effect, unstable atomization effect and long drying time. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a spraying device for surface treatment or coloring, which can increase the rotational kinetic energy / tangential velocity of the fluid, improve the mixing effect of the fluid, and have the effect of boosting , the atomiz...
