Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an internal filtering type dust collector. Background Art

[0002] The dust collector in the prior art is ideal for filtering fine and light dust. However, when cleaning the filter bag or filter cartridge, a vibration device is required to vibrate and clean the filter bag or filter cartridge.

[0003] The existing vibrating device is usually installed on the upper flower plate or the lower flower plate, and the vibrating device vibrates the flower plate to achieve the vibration of the filter bag or filter cartridge installed on the flower plate. However, the upper flower plate or the lower flower plate are respectively inside the dust collector case. The amplitude of the filter bag or filter cartridge vibrated by the vibrating device is small, and the vibration cleaning effect is poor. There are also methods that directly vibrate the filter bag or filter cartridge one-to-one through the vibrating device. In this way, more vibrating devices are required, which increases the cost. Secondly, the vibrating device still vibrates the filter bag or filter cartridge in a local position. The overall cleaning effect of the filter bag or filter cartridge is different, with good results in some parts and poor results in some parts. Utility Model Content
