Abstract

The invention provides a revolved body cathode with cooling rib rings, and relates to a cathode of plasma spray guns. A through cylindrical hole channel in the front and back direction is formed in the axial center of the revolved body cathode, the inner wall of the front end of the cylindrical hole channel forms an inner ring discharging surface, the outer wall of the front end of the revolved body cathode forms an embedding surface a, the outer wall of the rear end of the revolved body cathode forms an embedding surface b, and the protruding cooling rib rings are arranged on the outer wall of a revolved body between the embedding surface a and the embedding surface b. The revolved body cathode is mounted in a cathode base in an embedding mode, the space between the inner wall of the cathode base and the outer wall of the revolved body cathode forms a cooling water jacket, an embedding port a is formed in the wall of the front end of the cathode base, the embedding surface a of the revolved body cathode is tightly embedded into the embedding port a of the wall of the front end of the cathode base, an embedding port b is formed in the wall of the rear end of the cathode base, and the embedding surface b of the revolved body cathode is tightly embedded into the embedding port b of the wall of the rear end of the cathode base. Through the application of the revolved body cathode with the cooling rib rings in plasma heating spray guns, the defect that the cathode is prone to being ablated is overcome.

Description

technical field [0001] The invention relates to plasma equipment, in particular to a cathode of a plasma spray gun. Background technique [0002] At present, plasma technology has been widely used, industrially used in plasma ignition, plasma spraying, metal smelting, plasma heating to manufacture nanomaterials, cutting, garbage incineration and waste treatment, etc. Plasma is a state formed under the ionosphere or discharge phenomenon. In the plasma generator, the discharge makes the gas molecules lose the outer electrons to form an ion state, which generates high temperature through mutual collision. Therefore, the plasma torch The temperature of the center of the torch can be as high as tens of thousands of degrees Celsius, and the temperature of the edge of the torch can also reach more than thousands of degrees. When the processed substance is impacted by the high-temperature plasma, its molecules will decompose, and the atoms will recombine to form new substances. [...
