Switchable integrated control mechanism for collecting dust

Abstract

The invention relates to an integrated control mechanism for switchable dust collection, which includes a negative pressure air extraction system, an air outlet, and a negative pressure airflow chamber, and the air outlet exhausts the negative pressure airflow chamber through the connected negative pressure airflow system; the negative pressure airflow The top side of the warehouse is provided with at least one row of adjacent air inlets to open alternately to absorb waste and dust, so as to be suitable for the intake control part of different work stations; the upper part of the negative pressure airflow chamber is provided with a swirling negative pressure airflow channel connected with the air outlet ;The lower part of the swirling negative pressure airflow channel corresponding to the intake control part is provided with a dust collection box for primary treatment of waste and dust, and the bottom of the negative pressure airflow chamber is provided with a dust collection box for collecting the dust absorbed by the dust collection box; The air outlet corresponds to the swirling negative pressure airflow channel inside the negative pressure airflow chamber. There is also a filter box for secondary treatment of the negative pressure airflow; through the combination of switching and filtering processes, the pipe connection length of the swirling negative pressure airflow channel is effectively shortened. , so that the space occupied by the equipment is effectively reduced, and the cost is reduced.

Description

【Technical field】 [0001] The invention relates to a filter device for collecting waste dust after the positive electrode sheet or negative electrode sheet is scraped during the production process of electric cores, in particular to a switchable integrated control mechanism for dust collection. 【Background technique】 [0002] The improvement of lithium-ion battery performance has promoted the rapid development of the lithium-ion battery application industry, and the rapid development of the lithium-ion battery application field has continuously put forward higher requirements and more stringent conditions for lithium-ion batteries.

[0003] In the production process of battery pole pieces, the surface of positive or negative pole pieces is generally directly scraped and cleaned with a scraper. Floating in the working space, it is easy to cause secondary pollution, and it will also adversely affect the health of the workers and the quality of the pole piece; the existing filtering device for collecting waste and dust after coating and scraping the pole piece adopts the same one When the negative pressure vacuum system of the equipment is processed, it generally does not have the function of cross-application in time sequence. Most of the current mechanisms occupy a large space, the pipeline connection is long, the dust is inconvenient to clean, the pressure drop is obvious, and the dust collection effect is poor.
