A pipe inner wall coating brushing and soot blowing and vacuuming device

Abstract

The invention provides a pipe inner wall roughening and soot blowing and dust suction device, which comprises: a main body, a traveling mechanism, a roughening device, a soot blowing pipe, a dust suction pipe, a cleaning device and a main controller. The walking mechanism drives the napping device, soot blowing pipe, and dust suction pipe to move along the axis on the inner wall of the pipe, and the main rotating motor drives the napping device, soot blowing pipe, and dust suction pipe to move along the circumferential direction on the inner wall of the pipe, and the napping device stabilizes the inner wall of the pipe. For napping, the soot blowing pipe generates a strong blowing airflow to blow up the abrasive debris remaining after napping, the dust suction pipe sucks away the abrasive debris, and sprays the cleaning liquid on the cotton cloth of the single group of wiping cloth through the liquid spray head, and the cotton cloth is in contact with the inner wall of the pipe Wipe, effectively remove the residual wear debris, greatly improve the cleanliness of the grinding surface, make the inner wall of the pipe obtain a uniform and stable roughness surface, improve the adhesion between the two coatings, improve the spraying effect, and improve the inner wall of the pipe. anti-corrosion properties.

Description

technical field [0001] The invention relates to a pipeline coating treatment device, in particular to a pipeline inner wall coating roughening and soot blowing and dust suction device. Background technique [0002] Steel structures play an important role in ships and buildings. Steel pipes are a very common steel structure and are widely used. In order to prevent corrosion, the outer wall and inner cavity of the steel structure need to be coated. In order to improve the anticorrosion effect of the corrosion-resistant coating, multiple coatings are usually applied. In order to improve the bonding degree between the coatings, the current coating Before the next coating is applied, the roughening process is carried out to increase the roughness of the coating and eliminate defects such as orange peel and small sagging. However, due to the narrow space of the inner wall of the pipeline, the inner wall of the pipeline is rarely roughened in the industry at present, resulting in ...
