during glaze spraying operation, the special glaze spraying spray gun is in an initial state, the lifting piston and the inner gun barrel are both in an upper limit state, a glaze material feeding hole and an air inlet hole on the inner gun barrel are both in a closed state, and a valve core feeding hole of a valve core of the spray gun is also in a closed state; starting a glaze dry powder delivery pump and a high-pressure air pump, then starting a first glaze spraying air cylinder, then driving a first connecting plate and an inner gun barrel to synchronously move downwards, firstly communicating a glaze feeding hole with a glaze feeding pipe, and then enabling the glaze to enter a hollow cavity of the inner gun barrel; the inner gun barrel continuously moves downwards until the glaze material feeding hole is sealed by the inner wall of the outer gun barrel, then the air inlet hole of the inner gun barrel is communicated with the high-pressure air flow inlet pipe, at the moment, the high-pressure air flow enters the hollow cavity of the inner gun barrel and is fully mixed with the glaze material in the inner gun barrel, and the air inlet hole of the inner gun barrel is sealed by the inner wall of the outer gun barrel continuously moves downwards along with the inner gun barrel; then, a second glaze spraying cylinder is started, so that the second connecting plate and the lifting piston are driven to move downwards together, when the inner gun barrel descends to a lower limit position, the upper end of the valve core body is pushed into the inner gun barrel, and the lower end of the valve core body is connected with a glaze spraying hole of the outer gun barrel; the mixture of the glaze and the high-pressure gas in the inner gun barrel enters from the valve core feeding hole of the valve core body and is then sprayed out from the lower end of the valve core body and the glaze spraying hole; meanwhile, the flame gun sprays flame, the metal aluminum powder and the metal silicon powder spontaneously combust and release heat under the heating of the flame, simultaneously the glaze material is melted and directly sprayed on the surface of the blank in a molten state, and the glaze surface is spontaneously combusted after cooling to form a smooth glaze surface.
