[0003] In the prior art, when the graphite parts are coated with a protective layer, the graphite parts that need to be coated with a protective layer are first placed in the vulcanization furnace, and then the coating system is started to coat the graphite parts, and the graphite parts are treated with this structure. When coating, due to the large overall space of the vulcanization furnace, not only the coating medium used for coating is wasted during the coating process, but also it is difficult to coat the coating medium evenly on the outer surface of the graphite parts, which seriously affects Improve the coating effect and coating accuracy

The invention discloses a coating device with side channels. The coating device comprises a coating body arranged in a fluidization furnace. The coating body comprises a cover plate, a fluidization cavity, a base and a ventilation pipe. A coating medium recovery hole is formed in the cover plate. The cover plate is arranged at the upper end of the fluidization cavity in a covering mode. The base is arranged at the lower end of the fluidization cavity. Coating grooves communicating with the fluidization cavity are formed in the upper end of the base. A dividing groove communicating with the coating grooves is formed in the lower end of the base. The air inlet end of the ventilating pipe communicates with a material feeding device used for providing a coating medium. The air outlet end of the ventilating pipe communicates with the dividing groove in the base. The fluidization cavity is defined by a plurality of side plates. The multiple side channels are formed in the lower ends of the side plates in the length directions of the side plates at intervals. Coating holes with discharging openings being aligned with a graphite component are formed in the side channels in the length directions of the side channels at intervals. A coating channel is formed in the base. A feeding opening of the coating channel communicates with the dividing groove. A discharging opening of the coating channel communicates with the side channels.
Description
technical field [0001] The invention relates to the technical field of graphite parts coating, in particular to a coating device with side channels. Background technique [0002] After the production of graphite parts is completed, most graphite parts need to be coated with a protective layer on the outside, such as pyrolytic carbon layer and silicon carbide layer, to enhance the comprehensive performance of graphite parts. [0003] In the prior art, when the graphite parts are coated with a protective layer, the graphite parts that need to be coated with a protective layer are first placed in the vulcanization furnace, and then the coating system is started to coat the graphite parts, and the graphite parts are treated with this structure. When coating, due to the large overall space of the vulcanization furnace, not only the coating medium used for coating is wasted during the coating process, but also it is difficult to coat the coating medium evenly on the outer surface ...
