Device for spraying interior of small-caliber pipe with dual-component coating

Abstract

The present invention discloses a device for spraying the interior of a small-caliber pipe with dual-component coating, which comprises a frame, a material box frame and two groups of supporting wheels, wherein a material bin is fixedly arranged on the material box frame, the material bin is provided with two material boxes through a partition plate, and the material bin is provided with two material covers; the material bin is fixedly provided with a pump motor and two feed pumps, an output shaft of the pump motor is fixedly connected with a driving gear, a main shaft of each feed pump is fixedly connected with a driven gear meshed with the driving gear, and a feed inlet of each feed pump is connected with the corresponding material box. A spraying motor is fixed on the frame, and an atomizing nozzle is fixed on an output shaft of the spraying motor. The atomizing nozzle is a conical cover with the small front part and the large rear part, and a plurality of spraying holes are formedin the tapered side wall of the atomizing nozzle. The device has the advantages of simple structure, low cost and good reliability, a uniform and dense, bubble-free and interlayer-free coating can beformed, and a qualified anti-corrosion layer can be obtained.

Description

technical field [0001] The invention relates to an in-pipe spraying device, in particular to a small-diameter in-pipe two-component paint spraying device. Background technique [0002] The anti-corrosion pipe fittings need to be pretreated by spraying inside; the existing spraying device in the pipe can only spray one-component paint, and the structure of the paint feeding into the nozzle is relatively complicated, resulting in high cost and poor reliability, and it is difficult to form a uniform, dense, A bubble-free and interlayer-free coating cannot guarantee a qualified anti-corrosion coating. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned shortcomings in the prior art, and to provide a small-diameter tube two-component paint spraying device, which has the advantages of relatively simple structure, low cost and good reliability, and can form uniform, dense, bubble-free and No interlayer coating, can get qualif...
