Description

Technical Field

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

[0002] Conventional dust collectors have only one-stage filter assembly for filtering and dust removal. When the dust content is low, as long as the filter area of ​​the filter assembly basically meets the requirements, the normal operation of the equipment can be achieved. However, when the dust content is high, not only a large filter area needs to be added, but also the equipment dimensions need to be increased, and the number of back-blow valves also needs to be increased, thereby doubling the manufacturing cost of the equipment. In the patent published on the date of CN112870899A, a cyclone separator is added in the middle of the interior, and another device is installed inside the equipment to divide it into two working chambers, with a cyclone set in the middle. The rotation circle of the cyclone is small, and it is not easy to settle once high-pressure gas is used. The air inlet needs to pass through the inner wall of the outer device, so it is not easy to install and cannot withstand high pressure. Utility Model Content
