Pipeline inner-wall spraying device

Abstract

A pipeline inner-wall spraying device comprises a rack (1), and a circle of spraying pipes (2) are arranged on the ring edge of the rack and are connected with a negative pressure generator (3) and a paint tank body (4); in the use process, the negative pressure generator (3) is started, and paint is evenly sprayed to the inner wall of a pipeline (5); a stepping device (6) is arranged at the bottom of the rack, and easily moves in the pipeline (5); a traction rope (7) is arranged at the tail end of the rack (1), and an LED lighting assembly (8) is arranged, so that the pipe wall condition is observed; a remote control device (9) is arranged and controls various spraying process parameters; and the spraying pipes (2) are of an atomization spraying structure. Spraying to the interior of the pipeline can be rapidly and evenly achieved, and due to the fact that ring spraying is adopted, the spraying effect can be ensured.

Description

technical field

[0001] The invention relates to a pipeline inner wall spraying device. Background technique

[0002] For some special pipelines, it is necessary to spray the inner wall of the pipeline. Electrophoresis is one way, but the cost is high and the spraying speed is not high. Contents of the invention

[0003] The object of the present invention is to provide a pipe inner wall spraying device.

[0004] The present invention is achieved like this. The spraying device for the inner wall of the pipeline includes a frame, and a spraying pipe is arranged on the edge of the frame. The spraying pipe is connected with a negative pressure generator and a paint tank. When in use, the negative pressure generator is activated to spray the paint evenly on the inner wall of the pipeline.

[0005] The spraying device on the inner wall of the pipeline is equipped with a stepping device at the bottom of the frame, which is convenient to move in the pipeline.
