Paint spraying device for boiler accessory machining

Abstract

The invention discloses a paint spraying device for boiler accessory machining. The paint spraying device for boiler accessory machining comprises a bottom plate, two supporting plates, two fixing plates and a swing mechanism; an installing plate is arranged on the two supporting plates and provided with a round hole; a round groove is formed in the inner wall of the round hole and connected with a movable block through a rotation rod; the movable block is provided with a first connecting pipe provided with a first sprayer; a reciprocating lead screw is arranged between the two fixing plates and is in threaded connection with a fixing sleeve; and the fixing sleeve is connected with the movable block through a telescopic rod. The paint spraying device can better conduct paint spraying on different surfaces of ventilation gaps, paint spraying on the surface of a fire grate is more in place and thorough, accordingly, better fire grate corrosion prevention is better facilitated, and the service life of the fire grate can be better prolonged.

Description

technical field [0001] The invention relates to the technical field of boiler fittings, in particular to a paint spraying device for processing boiler fittings. Background technique [0002] Boiler accessories are a general term for boiler accessories. The grate is one of many boiler accessories. The grate is composed of a frame and a grate piece. The grate piece is usually made of cast iron. There is a certain ventilation gap between the grate. During the processing of the grate, in order to prolong the service life of the grate, it is usually necessary to spray paint on the grate to prevent the iron grate from being corroded. During the painting process of the used grate, basically only the surface can be painted, and it is difficult to spray paint on the ventilation gaps between the grate pieces, which leads to the incomplete painting of the grate and the inability to better carry out the grate. Anti-corrosion, it is impossible to better extend the service life of the gr...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the following shortcomings in the prior art. The currently used fire grate can basically only spray paint on the surface during the painting process, and it is difficult to spray paint on the ventilation gaps between the fire grate sheets, resulting in The paint spraying on the grate is not in place, the fire grate cannot be better protected, and the service life of the fire grate cannot be better extended, so a painting device for boiler accessories processing is proposed
