Description

Technical Field

[0001] The invention belongs to the technical field of dust removal equipment, and in particular relates to a workpiece grinding and dust removal device and method. Background Art

[0002] In modern industry, grinding is an inevitable process in the manufacturing workshop of the machinery industry. However, this process will not only make the workpiece meet the requirements of the drawings, but also bring a lot of dust. The dust generated by grinding is rich in metal particles, which are very easy to spread. Not only will it adhere to the surface of equipment and workpieces, causing serious impacts on the workshop environment and safe production, but it will also cause great harm to the physical and mental health of employees.

[0003] In recent years, with the acceleration of global industrialization, the emission of pollutants such as industrial dust has continued to increase, posing a serious threat to the environment and human health. In the machinery and heavy industry, there are a large number of small workpiece grinding operations. In order to reduce the emission of pollutants, the traditional mobile high-power industrial dust collector is placed in the workpiece grinding area. The equipment is equipped with a flexible suction arm with a horseshoe-shaped suction hood on its head. However, it was found during use that the horseshoe-shaped suction hood is small in size and has a limited effective dust collection range, resulting in general dust removal effect during large-scale continuous production operations. Summary of the invention
