Abstract

The invention discloses an efficient molybdenum spraying device comprising a spraying gun, a powder feeder, a drying device and a control system. The powder feeder is connected with the spraying gun through a pipeline. The drying device is arranged in the position, between the powder feeder and the spraying gun, of the pipeline. The spraying gun, the powder feeder and the drying device are all electrically connected with the control system. The spraying gun comprises a gun body and a gun cylinder. The gun cylinder is arranged on one end face of the gun body. A fuel inlet and an air inlet are formed in one end face, far from the gun cylinder, of the gun body. A fuel chamber is arranged in the gun body and communicates with the fuel inlet and the air inlet. An outlet of the fuel chamber communicates with the gun cylinder. A powder inlet channel is formed in the side face of the gun body and communicates with the powder feeder through the pipeline. The structure is designed reasonably, powder needle blocking is avoided, and continuous construction of spraying operation is guaranteed; and meanwhile, the spherical nozzle design is achieved, and the angle of a spherical nozzle can be adjusted through a tool according to the requirements, so that the spraying angle is changed.

Description

technical field [0001] The invention relates to the technical field of thermal spraying equipment, in particular to a high-efficiency molybdenum spraying device. Background technique [0002] As a new surface protection and surface strengthening process, flame spraying technology has developed rapidly in the past 20 years since J.A. Browning of the United States invented the high-speed oxygen-gas flame spray gun HVOF in 1981, and has become the field of metal surface engineering. A very active branch of . Using the flame as the heat source, the metal and non-metallic materials are heated to a molten state, and a mist flow is formed under the push of the high-speed airflow, which is sprayed onto the substrate. When the sprayed tiny molten particles hit the substrate, plastic deformation occurs and becomes a sheet-like superposition. The coating is deposited, a process called flame spraying. Flame spraying can spray metal, ceramics, plastics and other materials. It is very f...
