Description

Technical Field

[0001] The utility model belongs to the technical field of dust collection, and in particular relates to a dust collection device for centrifugal sand making. Background Art

[0002] Centrifugal sand making machine is a machine that uses high-speed rotating centrifugal force to classify materials and separate sand that meets the requirements. Its working principle is roughly as follows: raw sand and water are sprayed into the drum of the centrifugal sand making machine through the feed port and are separated by the centrifugal force. The separated water and fine sand are discharged from the centrifugal sand making machine through the overflow pipe, while the coarse sand is output through the discharge port. After multiple rotations, the appropriate particle size is obtained. The dust generated during the centrifugal sand making process needs to be collected and processed.
