[0002] The sanding belt machine includes a sanding belt, a sanding belt housing for accommodating the sanding belt, a motor, a motor housing for accommodating the motor, a handle, a driving wheel, a driven wheel, and a transmission device connecting the motor and the driving wheel. The sanding belt machine is used when grinding and polishing steel. The sanding belt machine will produce iron filings, waste chips, dust and other substances when working. These substances will not only cause air pollution, but also affect the health of the staff. Therefore, general steel sanding belt machines are equipped with dust removal devices. The dust removal equipment is used to extract iron filings, waste chips and other substances into the filter element, and the filter element is used to collect iron filings, dust and other substances. With long-term use, the filter element will also be blocked by waste chips and other substances, thereby affecting the dust removal effect of the dust removal device. At this time, the filter element needs to be replaced. However, the replacement of the filter element in the existing dust removal device is relatively troublesome, which brings difficulty to the replacement of the filter element; in addition, iron filings and other substances that enter the filter element are easy to clog the filter element. For this reason, we propose a dust removal device for a steel sanding belt machine that is easy to replace the filter element. Utility Model Content
