[0002] At present, a large amount of dust is generated in the production and manufacturing process of precious metals. In order to deal with the dust, dust removal equipment is needed for recycling. Precious metals mainly refer to eight metal elements, including gold, silver and platinum group metals (ruthenium, rhodium, palladium, osmium, iridium, platinum). Most of these metals have beautiful colors and strong chemical stability, and are not easy to react with other chemical substances under normal conditions.

[0003] For example, a dust removal device for a precious metal recovery system disclosed in the authorization announcement number CN220239590U inserts a connecting frame into the vertical area through a slot with the cooperation of a filtering mechanism, so that the dust passing through the vertical area will be filtered and collected by the filtering mechanism, thereby facilitating the removal of the connecting frame from the slot to clean the small precious metal particles in the collected dust, thereby improving the convenience of work.

[0004] However, the above-mentioned filter mechanism is used to contain and collect dust, which will continuously accumulate dust, causing a large amount of dust to accumulate inside the filter mechanism, causing the filter mechanism to be blocked, thereby affecting the normal operation of the entire dust removal equipment. For this reason, we propose a precious metal recovery dust removal equipment. Utility Model Content
