Abstract

The invention relates to a hypersonic speed jet oxygen lance. The hypersonic speed jet oxygen lance comprises a heat dissipating housing of which the top part is provided with a reinforced cover plate, wherein an air pressure detection valve is arranged at one end of the reinforced cover plate; one end of a reinforcing rib is fixed to the air pressure detection valve, and the other end of the reinforcing rib is fixed through a bolt; an inlet tube is inserted into the middle of the reinforced cover plate; a fixing plate in which a rubber layer is arranged is mounted between the inlet tube and the reinforced cover plate; a reinforcing part on which a sealing cover is arranged is mounted on the fixing plate; an air port below which fixing rods are arranged is formed in the upper right side of the heat dissipating housing; the two fixing rods are correspondingly fixed to the upper side and the lower side of the inlet tube, and the fixing plate between the fixing rods is fixed through a nut; an elbow in which a reinforcing plate is arranged is mounted at the lower left side of the air port and connected with draught fans; the draught fans are positioned at two sides of the cover plate and connected with an accelerating chamber of which the bottom part is connected with a mixing chamber. The hypersonic speed jet oxygen lance is simple in structure, close to fit, stable, firm, high in safety, high in flowing speed, high in driving force, high in working efficiency, high in service life, and low in cost.

Description

technical field [0001] The invention specifically relates to a supersonic jet flow oxygen lance. Background technique [0002] Supersonic spraying processing is widely used in the product manufacturing industry. Supersonic spraying technology includes supersonic arc spraying and supersonic flame spraying. For supersonic flame spraying, the principle is to use propane, propylene and other hydrocarbon gases or aviation kerosene, alcohol Combustion of liquid fuel and high-pressure oxygen in a combustion chamber or a special nozzle produces a high-temperature and high-pressure flame flow with a temperature of 3200°C and a speed of over 1500m / s. The powder is sent into the flame axially or radially to produce melting or semi- The molten particles, which impact at high speed, deposit on the surface of the substrate to form a coating. [0003] During supersonic spraying processing, due to the unreasonable structural design of the nozzles used in traditional supersonic processing e...
