Device for coating outer wall of pipeline

Abstract

The invention belongs to the technical field of repairing of a coating on the outer wall of a pipeline, particularly relates to a device for coating the outer wall of the pipeline, aims to solve the problem of smell diffusion of polluted dust and paints during coating construction of the outer wall of the pipeline, and provides the coating device which can guarantee no leakage of pungent smell of the polluted dust and paints. The device is characterized by comprising a lower base, an upper base, a visible window, rubber glove holes, round guide rails, hinges, a hasp lock, a pumping hole and an air inlet, wherein the lower base and the upper base are arranged opposite to each other; one end of the lower base and one end of the upper base are in movable connection through the hinges; the other ends of the lower base and the upper base are fixedly connected through the hasp lock; the lower base and the upper base are mounted on a pipeline; the guide rails are arranged between the lower base and the outer wall of the pipeline and between the upper base and the outer wall of the pipeline; the visible window and the rubber glove holes are formed in the outer wall of the upper base; the pumping hole is formed in the lower base; and the air inlet is formed in the upper base.

Description

technical field [0001] The invention belongs to the technical field of pipeline outer wall coating repair, and in particular relates to a pipeline outer wall coating coating device. Background technique [0002] In nuclear power plants, it is often necessary to paint the outer wall of the pipeline for anti-corrosion treatment, which involves two main processes: grinding and painting. The dust generated during the grinding process is difficult to control. Traditional dust-proof equipment, such as dust-proof sheds, dust-proof grinders, etc., will still have dust overflow during the grinding operation, and the effect is poor. The dust in the air will affect the construction the health of personnel. Especially in nuclear islands, some pollutants may float in the air along with polluted dust, resulting in nuclear pollution of personnel and equipment, which will seriously damage the health of construction workers, and the treatment procedures for equipment decontamination are als...
