Switchable dust collection integrated control mechanism

Abstract

The invention relates to a switchable dust collection integrated control mechanism. The mechanism comprises a negative pressure air suction system, an air outlet and a negative pressure airflow cabin, wherein the air outlet performs air suction on the negative pressure airflow cabin through the connected negative pressure air suction system; an air inlet control part for controlling at least one row of adjacent air inlets to be alternately opened for adsorbing wastes and dust so as to be suitable for working in different positions is arranged on the top side of the negative pressure airflow cabin; a convolutional negative pressure airflow channel communicating with the air outlet is formed in the upper part of the negative pressure airflow cabin; a dust suction box for performing primary treatment on the wastes and the dust is arranged at the lower part, corresponding to the air inlet control part, of the convolutional negative pressure airflow channel; a dust receiving box for collecting the dust adsorbed by the dust suction box is arranged at the bottom of the negative pressure airflow cabin; and a filtering box for performing secondary treatment on negative pressure airflow is further arranged on the air outlet corresponding to the convolutional negative pressure airflow channel in the negative pressure airflow cabin. By integrally combining switching and filtering processes, the pipeline connection length of the convolutional negative pressure airflow channel is effectively reduced, so that the space occupied by a device is effectively reduced and the cost is lowered.

[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.
