The invention relates to a spraying device, in particular to a displacement airless spraying device of low-pressure storage tank. The device comprises a coating preparation tank, a coating feed conveying pump, a coating pressing spraying tank, an airless spraying nozzle set and a flushing water pump, wherein the discharge hole of the coating preparation tank is connected with the feeding hole of the coating pressing spraying tank through a conveying pipeline, and the coating feed conveying pump is arranged on the conveying pipeline; the discharge hole of the coating pressing spraying tank is connected with the airless spraying nozzle set through a coating spraying pipeline; the flushing water pump is connected with the coating preparation tank, the coating feed conveying pump, the coating pressing spraying tank and the coating spraying pipeline through flushing water pipelines respectively; and the conveying pipeline, the coating spraying pipeline, the flushing water pipelines and the compressed air input pipeline of the coating pressing spraying tank are provided with a pneumatic quick switching set formed by an electric automatic control system respectively. The device can spray a protective coating on the surface of a blank on line before the metal blank is heated so as to reduce the oxidation burning loss of the metal and relieve the surface quality deterioration and defect problems of the blank.
Description
Technical field [0001] The invention relates to a spraying device, in particular to a low-pressure storage tank replacement method airless spraying device for spraying a high-temperature resistant paint before a metal blank is heated. Background technique [0002] In the metal heating process, whether it is a rolling, forging heating process, or a pure heat treatment process, it will deliberately overcome the negative effects of heating on the substrate, including oxidation burnout, surface element depletion and decarburization, and deterioration of surface quality. Product yield rate and so on. There are many solutions, but they are not ideal. In recent years, the methods of applying high-temperature protection of coatings have increasingly demonstrated the application value of this method through actual applications. Corresponding coatings are usually high-temperature resistant coatings. The use of coating protection methods can significantly reduce the oxidation burning of me...
