Jacket cooling disassembling type flame spraying device

Abstract

The invention relates to a jacket cooling disassembling type flame spraying device, which comprises an outer shell body, an inner shower nozzle arranged in the outer shell body, and a bushing, whereinthe outer shell body comprises a circular tube shaped connecting tube and a tapered tube shaped heat dissipation tube; the inner spray nozzle comprises a cylinder body of which the outer side wall isof a cylindrical structure; the central shaft of the cylinder body is provided with a circular truncated cone shaped first through hole; the center of the first end of the cylinder body is provided with a cylindrical boss; and the bushing comprises a tapered tube shaped first tube body and a circular tube shaped second tube body, wherein a clapboard is arranged in the second tube body. The outershell body, the inner shower nozzle and the bushing in the jacket cooling disassembling type flame spraying device adopt a detachable structure, so that an installation and replacement operation is simple and convenient. A jacket cooling way is adopted for the bushing so as to be favorable for controlling an injection temperature and improving subsequent injection quality; the inner surface of thebushing is subjected to surface treatment so as to be convenient to remove coking objects on the surface, and a situation that the bushing is frequently replaced is avoided.

Description

technical field [0001] The invention relates to a jacket cooling and detachable flame spraying device, which belongs to the technical field of surface treatment. Background technique [0002] In the field of surface treatment, a spray gun is often used to spray the inner wall of the pipe or the inner wall of the cylinder. The injection end of the current spray gun usually adopts a conical tubular structure, and the spray material is sprayed from the center hole of the conical tube, and then blocked by a mandrel, so that the spray material sprayed inside the conical tube diffuses in a conical shape. It is beneficial to complete the spraying operation on the inner wall of the pipeline at one time. [0003] However, the above-mentioned method has the following defects: the injection end installed on the spray gun is usually made of ceramic material, and with long-term use inside the injection end, it is easy to produce coking or slagging, resulting in the need for frequent rep...

Problems solved by technology

[0003] However, the above-mentioned method has the following defects: the injection end installed on the spray gun is usually made of ceramic material, and as the interior of the injection end is used for a long time, it is easy to produce coking or slagging, resulting in the need for frequent replacement of the injection end

In addition, for some special processes, it is necessary to adjust the temperature of the spray material during the spraying process. At present, when adjusting the temperature process, it can only be interrupted, and then adjusted by adjusting parameters such as the working current and voltage of the spray gun, which is not conducive to continuous spraying.
