The support rod is provided with a driving mechanism inside to drive a cleaning brush to reciprocate vertically to scrape dust off the inner wall of the filter cartridge, and the side of the filter cartridge is provided with a dust suction component to absorb the dust scraped off by the cleaning brush. When cleaning the dust on the inner wall of the filter cartridge, the cylinder is started to drive the connecting pipe to move up and down reciprocally, so that the connecting pipe is threadedly connected to the driving block against the threaded pipe, and the cylinder is used to cause the threaded pipe to rotate up and down to drive the cleaning brush to scrape and clean the inner wall of the filter cartridge. During the cleaning process, the vacuum pump is started to generate negative pressure at a number of through holes, and the dust cleaned by the cleaning brush is absorbed until it falls on the top of the filter screen in the dust collecting box for collection. After cleaning, the box door is opened to disassemble and clean the filter screen, thereby preventing small gravity dust from spreading inside the filter cartridge and adhering to the inner wall of the filter cartridge after cleaning.

Description

A cartridge dust collector with dust cleaning function

Technical Field

The utility model relates to the technical field of dust removal, and in particular to a cartridge dust collector with a dust cleaning function.

Background Art

Cartridge dust collectors are composed of filter cartridges as filter elements or use pulse jets. Cartridge dust collectors can be divided into oblique insertion type, side-mounted type, hanging type, and top-mounted type according to the installation method. Cartridge dust collectors can be divided into long fiber polyester cartridge dust collectors, composite fiber cartridge dust collectors, antistatic cartridge dust collectors, flame retardant cartridge dust collectors, membrane cartridge dust collectors, nano cartridge dust collectors, etc. according to the cartridge material. Cartridge dust collectors have the advantages of small size, high efficiency, low investment, and easy maintenance. However, due to their small equipment capacity, they are difficult to combine into large air volume equipment, the filtration wind speed is low, and the application range is narrow. They are only used in industries such as grain and welding, so they have not been widely promoted for many years.

After searching, the patent with publication number CN109331572A discloses a high-efficiency filter cartridge dust collector cleaning device, including a filter cartridge, a No. 1 rotating shaft, an elliptical ring and a cleaning brush.
