Description

Technical Field

[0001] The utility model relates to the technical field of dust recovery devices, in particular to a dust recovery device for white corundum powder processing. Background Technique

[0002] During the production process of white corundum micropowder, due to the small particle size of the product, there will be a problem of dust floating during the production process, resulting in turbid on-site air and increased dust density. If there is an open fire on-site, in severe cases, there will be a problem of dust explosion, which will further affect the health of the staff. When collecting dust, it is not possible to collect the dust well in a centralized manner, resulting in adsorption onto many parts, which will affect the service life of the machine over time.

[0003] The prior art discloses CN220294837U, a fine grinding device for white corundum processing, including a mounting frame. A rotating shaft I is rotatably arranged on the mounting frame. A grinding cylinder is arranged on the rotating shaft I. A rotating shaft II is rotatably arranged in the grinding cylinder. A motor is arranged on the side of the grinding cylinder. The motor is used to rotate the rotating shaft II. A grinding assembly is arranged on the surface of the rotating shaft II. The beneficial effect lies in that: the white corundum can be finely ground through the cooperation of the grinding assembly and the inner wall of the grinding cylinder. The filter screen for filtering white corundum powder is located on the side of the grinding cylinder and does not contact the white corundum during grinding. When taking out the white corundum powder, the restriction of the limiting assembly on the rotating shaft I is released and the grinding cylinder is rotated so that the conical cover faces downward. At this time, the ground white corundum powder can be poured out. The white corundum powder blocked at the filter screen can be dredged through the air pump body, thus avoiding blockage during the grinding process and taking out of white corundum.

[0004] In the above application, by stopping the operation of the grinding equipment and then pouring out the produced powder, the process of powder collection must be carried out during machine downtime, which affects the work efficiency. Content of the Utility Model
