Description

Technical Field

[0001] This utility model relates to the technical field of polishing dust removal devices, specifically a wet polishing dust removal device. Background Technology

[0002] Polishing metal parts on a workbench generates a lot of metal dust, which can be harmful to workers if inhaled. Metal dust can also accumulate and cause electrical conductivity when it falls onto the circuitry, thus damaging the equipment. Dust removal devices are usually provided.

[0003] For example, Chinese patent CN220294340U discloses a polishing dust removal device, belonging to the field of polishing dust removal. It includes an air intake, and a first-stage extraction pipe is fixedly connected to the air outlet of the air intake. The utility model sets up a motor, a threaded rod, a cleaning brush, and a limiting block inside the dust collection box. The motor drives the threaded rod fixedly connected to the output shaft to rotate, which drives the cleaning brush connected to the threaded rod to move up and down. This can better clean the filter screen and prevent excessive dust accumulation on the filter screen surface after long-term filtration, thus reducing the filtration effect. Moreover, it eliminates the need for manual disassembly and cleaning, reducing labor costs and solving the problem of frequent manual disassembly and cleaning of the filter screen, which increases labor costs. The limiting block fixedly connected to the bottom of the threaded rod can better limit the cleaning brush when it moves, preventing it from falling off, thereby improving the practicality of the polishing dust removal device.

[0004] Although the aforementioned patent improves the practicality of a polishing dust removal device, the dust removal process using a single air intake when polishing metal parts is limited, resulting in a generally poor dust removal effect and reduced practicality. Utility Model Content

The dust remains on the upper surface of the first filter. The continuous operation of the water pump continuously forms a water curtain. The combination of the water curtain and the at least two suction cylinders enhances the dust removal effect. Attached Figure Description
