Abstract

The invention relates to the technical field of supersonic speed sand-blasting guns and in particular to a handheld supersonic speed sand-blasting gun and a using method thereof. The handheld supersonic speed sand-blasting gun comprises a gun barrel. The lower end of the gun barrel is provided with a handle. The front end of the gun barrel is provided with a nozzle. The rear side of the gun barrelis provided with a bi-directional valve. The upper end of the bi-directional valve is provided with a bi-directional switch. The upper side of the gun barrel is provided with an oil valve into whichfuel oil enters. One side of the oil valve is provided with an oil pipe port connected with an oil pipe. The gun barrel comprises a sand pipe, a flame pipe, an intermedium pipe and an outer pipe whichare installed from inside to outside along the same axial direction. The handheld supersonic speed sand-blasting gun is capable of solving deficiency of a traditional sand-blasting technology, through combusting fuel in an internal combustion chamber of the spray gun, enabling a gas to be expanded, thereby enabling particles to be accelerated by drive of a high-temperature high-pressure flame flow, spraying in a supersonic speed state, and providing a stable supersonic speed air flow, wherein a sand speed is 2.5-3.5 times of a traditional technology. Cleaning quality is high, efficiency is rapid, and cost is low, so a production rate is improved, and economic benefit is promoted.

Description

technical field [0001] The invention relates to the technical field of supersonic sandblasting guns, in particular to a hand-held supersonic sandblasting gun and its usage method. Background technique [0002] Sand blasting is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, corundum, iron sand, Hainan sand) to the surface of the workpiece to be treated at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes. , due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpiece, increasing it and coating Th...
