Abstract

The invention provides an injection device for surface treatment or coloring. The injection device comprises a nozzle body, a liquid channel, a gas channel and a temperature adjusting gas channel arearranged in the nozzle body, the liquid channel is positioned in the center of the nozzle body, the gas channel is positioned on the radial outer side of the liquid channel, and the temperature adjusting gas channel is positioned on the radial outer side of the gas channel. The liquid channel sequentially comprises a first diameter part (2), a second diameter part (3), a first conical part (4), adiffusion cavity (5) and an outlet part (6). The injection device is characterized in that a plurality of swirl plates (41) uniformly distributed in the circumferential direction are arranged on the inner circumferential surface of the first conical part, and a plurality of swirl grooves (42) distributed in the axial direction of the swirl plates are arranged at the radial inner edges of the swirlplates. According to the injection device for the surface treatment or coloring, the rotating kinetic energy / tangential speed of fluid can be increased, the mixing effect of the fluid is improved, the pressurizing effect is achieved, atomization of a nozzle is uniform, the droplet size is small, and the injection / atomization effect is excellent; and the flow direction of the temperature adjustinggas is controllable and accurate, 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...
