Abstract

The invention relates to a ceramic powder spraying device which comprises a spray nozzle made of metal, wherein the front end of the spray nozzle is connected with a negative electrode; a direct voltage is additionally arranged between the spray nozzle and the negative electrode; air inlet channels are formed in the spray nozzle and in two sides of the negative electrode; a flame channel communicated to the rear end of the spray nozzle is formed in the spray nozzle along an axial direction of the negative electrode and is connected with the air inlet channels; and powder inlet holes are formed in the spray nozzle and in an outlet of the flame channel and are communicated with the flame channel. The spraying device with the structured spray nozzle is controllable in airflow, thin and uniform in coating and simple in process, and can be used for spraying various ceramic coatings of metal oxides, carbides, silicides, borides and the like.

Description

technical field [0001] The invention relates to the field of ceramic production equipment, in particular to a rotary ceramic coating production equipment. Background technique [0002] In the production of ceramic products, it is often necessary to attach the ceramic powder layer to the surface of metal, glass and other substrates; the existing spraying device, when spraying ceramic powder, the spraying is uneven and the spraying layer is too thick. Contents of the invention [0003] In view of the above problems, the applicant has designed a ceramic spraying device with an improved structure. [0004] The technical scheme adopted in the present invention is as follows: [0005] A ceramic spraying device, including a nozzle made of metal, the front end of the nozzle is connected with a cathode, and a DC voltage is applied between the nozzle and the cathode; inside the nozzle, there are air inlet channels on both sides of the cathode; inside the nozzle, the cathode is axia...
