A dirt collecting system for a vacuum cleaner includes a dirt cup formed from a cylindrical sidewall having a disc shaped member separating the dirt cup into an upper portion and a lower portion. The dirty airstream flows past the disc shaped member from the upper portion to the lower portion through a small gap between the outer periphery of the disc shaped member and the sidewall of the dirt cup. The disc shaped member is supported on a centrally located conduit which has apertured walls located both above and below the disc shaped member. The apertured walls allows the airstream to flow into the conduit for further filtering or exiting the dirt cup. The apertured wall located above the disc shaped member improves sustained performance by enabling the airstream to continue to flow through the dirt cup as the lower portion of the dirt cup fills with large dirt particles and the apertured wall located beneath the disc shaped member becomes increasingly restricted. In the various embodiments of the invention, the airstream is directed through the conduit to a fine particle filter located in a compartment at the bottom of the dirt cup, at the top of the dirt cup or into filter sock located at the upper end of the dirt cup. Alternately, the fine particle filter may be located in a separate container located above or below the dirt container.

The invention discloses non-contact dust removal equipment, system and method, and relates to the technical field of battery pole piece dust removal. The non-contact dust removal equipment comprises a fan, an air blowing pipe, a dust removal tool, an air suction pipe, a dust collection system and an air inlet pipe. The output end of the fan is connected with the air inlet end of the dust removal tool through the air blowing pipe. The air suction end of the dust removal tool is connected with the input end of the dust collection system through the air suction pipe, and the output end of the dust collection system is connected with the input end of the fan through the air inlet pipe. The equipment has the advantages that secondary pollution of a workshop caused by negative pressure dust collection is avoided, the structure is simple, the size is small, occupied space is reduced, and the equipment can be directly placed beside original process equipment of the workshop.
