Technical Field
The utility model relates to a liquid spray gun structure field, in particular to spray gun for wet process granulator.
Background
The wet granulator sprays adhesive on the uniformly stirred powder material in the working process to wet and adhere the material into granules. In the process of spraying the adhesive, the adhesive needs to be dispersed and atomized, so that the adhesive is atomized into fine droplets to be sprayed on the surface of the powder material. The main function of the spray gun is to spray liquid adhesive in air medium through the nozzle, and break the adhesive into tiny particle drops under the action of internal and external pressure of the nozzle. Because the adhesive has certain viscosity, the common spray gun cannot uniformly atomize the adhesive, thereby influencing the uniformity of subsequent powder granulation.
