Description

Technical Field

[0001] The utility model relates to the technical field of purification and dust removal, in particular to a lithium battery recycling waste gas purification and dust removal processing device. Background Art

[0002] When recycling waste lithium batteries, crushing is one of the processes for recycling waste lithium batteries. When crushing waste lithium batteries, a crusher is usually used to crush them directly.

[0003] In order to improve the environmental friendliness of the crushing of waste lithium batteries, a dust collector will be installed on the top of the waste lithium battery crusher to filter and purify the exhaust gas generated by it, and the dust collector is usually used in conjunction with a dust hood.

[0004] In order not to affect the feeding of the crusher, the vacuum cleaner and the dust hood are usually directly set on the top of the crusher when in use, so that there is a certain gap between the dust hood and the crusher feed hopper. However, when there is a certain gap between the dust hood and the crusher feed hopper, the exhaust dust discharged from the top of the feed hopper of the crusher will pass through the gap between the dust hood and the crusher and fall to the outside, thereby polluting the air. It is not convenient to place the dust hood directly on the top of the feed hopper on the top of the crusher to reduce the probability of exhaust dust falling from the gap between them.
