Anticorrosion spraying device for chimney inner wall and inner wall support hanger

Abstract

The invention discloses an anticorrosion spraying device for a chimney inner wall and an inner wall support hanger, and aims to solve the problems of low efficiency and high potential safety hazard since anticorrosion materials are mainly applied to a current chimney inner wall and a support hanger structure on the inner wall by manpower. The lifting of the whole device in a chimney is accomplished through a winch, a paint spraying assembly is utilized for spraying the anticorrosion materials to the chimney inner wall, and no worker needs to enter a chimney in the whole process, so that the potential safety hazard is greatly reduced, and the working efficiency is improved. A drive piece drives a spraying piece to move, and the distances between a spray gun A and the chimney inner wall as well as between a spray gun B and the support hanger on the inner wall are adjusted, so that the spraying assembly can be applicable to chimneys with different diameters, and the application range of the spraying assembly is enlarged; and paints on the chimney inner wall and the support hanger on the inner wall are quickly and uniformly heated and dried through a drying assembly. A main scraper piece rotates along with a main shaft, so that the chimney inner wall is uniformly cleaned; and through an auxiliary scraper piece, a cleaning range of the chimney inner wall is enlarged, and preparationis made for the cleaning work of the main scraper piece.

Description

Technical field [0001] The invention specifically relates to an anticorrosive spraying device for the inner wall and inner wall support and hanger of a chimney. Background technique [0002] A chimney is a structure that provides ventilation for the hot flue gas or smoke from a boiler, stove, stove or fireplace. The chimney is usually vertical, or as close to vertical as possible, to ensure a smooth flow of gas, and the air is sucked into the so-called chimney combustion or chimney effect. The space inside the chimney is called the flue. Chimneys may be found in buildings, steam locomotives and ships. The large chimney is also equipped with auxiliary parts such as supports, hangers or ladders for maintenance. The exhaust gas generated by the combustion of coal and other fuels in the combustion chamber is discharged from the boiler after cooling and dust removal by the dust collector. Finally, it is discharged to the atmosphere through the chimney to make the smoke The air reac...

AI Technical Summary

Problems solved by technology

At present, when anti-corrosion treatment is carried out on the inner wall of the chimney and the supports and hangers on the inner wall, it is generally to manually enter the chimney to apply anti-corrosion materials, but this construction method has the problems of low efficiency and high safety hazards
