Structure and method of sanding corner position of pipeline to improve wear resistance

Abstract

The invention relates to a structure and method of sanding a corner position of a pipeline to improve wear resistance and belongs to the technical field of sanding equipment and method. According to the technical scheme: a corner pipeline connector is composed of a straight pipe (1), an inclined pipe (2) and a clogging steel plate (3); the tail part of the straight pipe (1) is completely sealed bythe clogging steel plate (3); the top end of the straight pipe (1) is connected with a steel grit transporting pipeline (7); the middle part of the straight pipe (1) is connected with the inclined pipe (2); the inclined pipe (2) is connected with one end of a steel grit transporting pipeline I (13); the other end of the steel grit transporting pipeline I (13) is connected with a grit spraying nozzle (8); and a straight pipe tail part space (4) is formed between the connected position of the inclined pipe (2) on the straight pipe (1) and the clogging steel plate (3). The structure is simple and easy in manufacturing, barely increases the cost, and has a wide range of application; and the method is simple, convenient to implement, avoids direct impact on the pipeline, and extends service life of the pipeline.

Description

technical field [0001] The invention relates to a structure and a method for improving wear resistance at the corner position of a sand blasting pipeline, and belongs to the technical field of sand blasting equipment and methods. Background technique [0002] Sand blasting equipment is widely used in industrial production processes. Compressed air drives steel sand (steel wire segments or steel shots) to impact the surface of the workpiece at high speed, thereby cleaning up foreign matter such as oil stains and rust on the surface of the workpiece. From the sand storage tank to the sandblasting gun, the steel grit needs to pass through a long pipeline. During the operation of the sand blasting equipment, the steel grit constantly rubs against the inner wall of the sand blasting pipeline, especially when the vertical position changes to the horizontal position. For pipelines, the steel grit falls due to the acceleration of gravity, and when it turns suddenly at the corner, it...

Problems solved by technology

From the sand storage tank to the sandblasting gun, the steel grit needs to pass through a long pipeline. During the operation of the sand blasting equipment, the steel grit constantly rubs against the inner wall of the sand blasting pipeline, especially when the vertical position changes to the horizontal position. For pipelines, the steel grit falls due to the acceleration of gravity, and when it turns suddenly at the corner, it will inevitably collide violently with the inner wall of the pipeline at the corner. During the operation of the sand blasting equipment, the collision between the steel grit and the corner of the pipeline occurs continuously, resulting in The corners are severely worn, and the pipes often wear through from the inside, resulting in sand leakage

Some people set up another material storage platform at the elbow of the pipeline to reduce the impact of the material on the pipe wall. However, additionally setting the material storage platform requires special equipment and molds, which increases the production cost, is inconvenient to use, and improves the durability. Abrasive effect is not obvious
