Description

Technical Field

[0001] The utility model belongs to the technical field of sandblasting equipment, in particular to a sandblasting and rust removal device for the surface of a steel structure. Background Art

[0002] When stored, steel structures are prone to oxidation reactions with oxygen and water vapor in the air, forming a layer of rust on the surface. The rust needs to be removed before the steel structure is processed and used. Workers often need to use sandblasting equipment to remove rust from steel structures. The sandblasting device uses compressed air in a pipeline to transport powdered granular materials from one place to another. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles flush the surface of the steel plate, thereby improving the surface quality of the steel plate.

[0003] However, there are some problems with the prior art: during the sandblasting process on the steel plate surface, the nozzle of the sandblasting device is usually aimed at the middle area of ​​the steel plate surface, so the edge of the steel plate surface is less impacted by sand and gravel, which can easily cause uneven sandblasting. If the edge of the steel plate surface is to achieve a good rust removal effect, a longer sandblasting time is required, which reduces the processing efficiency. Therefore, we propose a sandblasting and rust removal device for steel structure surfaces. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a device for sandblasting and derusting the surface of a steel structure, which can improve the sandblasting and derusting effect on the steel plate by adjusting the direction of the nozzle.
