Description

Technical Field

[0001] The utility model relates to the technical field of dust removal of sandblasting machines, in particular to a dust removal device for sandblasting machines. Background Art

[0002] Sandblasting machine is a machine that uses compressed air as power to form a high-speed jet beam to spray material at high speed onto the surface of the workpiece to be processed, so that the mechanical properties of the outer surface of the workpiece surface change. It is usually used for cleaning, strengthening, polishing and decoration. The application range of sandblasting machine covers hardware processing, mechanical processing, automobile parts production, mold manufacturing and other fields. It has the advantages of high production efficiency and simple operation, and is widely used.

[0003] Sandblasting machines will generate a lot of dust during operation, which not only threatens human health, but also affects the performance and service life of the sandblasting machine. The dust removal devices used in most existing sandblasting machines can effectively remove most of the dust particles, but some smaller dust particles will still exist in the exhausted gas, and the dust removal effect is not thorough. During the long-term use of the sandblasting machine by the operators, these smaller dust particles will pose a threat to the health of the operators. For this reason, we propose a dust removal device for sandblasting machines. Utility Model Content
