Abstract

The invention provides a pipeline inner wall shot blasting device which is used for conducting shot blasting treatment on the inner wall of a pipeline. The conveying pipeline is of a tubular structureand is fixedly connected with the small end of a trumpet-shaped separation pipeline. A high-pressure air pipe is arranged on the conveying pipeline. A spray nozzle extending into the separation pipeline is arranged at the tail end of the high-pressure air pipe. A base is fixed to the separation pipeline. A plurality of wheel carriers arranged uniformly in the circumferential direction are slidably mounted on the base. An adjusting mechanism for driving the wheel carriers to move in the radial direction is arranged on the base. A high-pressure gas outer tube is arranged in the separation pipeline. A shot blasting channel is formed between the high-pressure gas outer tube and the separation pipeline. A high-pressure gas inner tube is arranged in the high-pressure gas outer tube. A high-pressure gas channel is formed between the high-pressure gas inner tube and the high-pressure gas outer tube. The high-pressure gas outer tube is provided with gas holes communicating with the high-pressure gas channel. The pipeline inner wall shot blasting device can conduct shot blasting operation on the inner wall of the pipeline conveniently and can conduct shot blasting on the inner wall of the whole pipeline.

Description

technical field [0001] The invention relates to the technical field of shot peening, in particular to a shot peening device for the inner wall of a pipeline. Background technique [0002] Shot peening, the surface of the workpiece to be blasted can be polished so that the workpiece to be blasted has certain physical properties. However, for pipelines, it is a technical problem to carry out shot peening on the inner wall of the pipeline, and it is difficult to evenly spray the projectiles on the inner wall of the pipeline during operation. Contents of the invention [0003] The object of the present invention is to provide a shot blasting device for the inner wall of a pipeline, which is used for conveniently performing shot blasting on the inner wall of the pipeline. [0004] The technical solution adopted by the present invention to solve the technical problem is: a shot peening device for the inner wall of the pipeline, which is characterized in that it includes a deliv...
