[0002] A dust collector is a device that separates sand from the air. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency.

[0003] Generally, wind towers are installed in locations with strong winds and sand. In order to ensure that the internal equipment will not be affected by the wind and sand, a filter dust collector is needed to filter the sand particles in the air. The filter placement generally uses cyclone filtration or filter bag and filter mesh filtration. That is, the filter dust collector is installed at the location where the wind tower is installed, and the external air containing wind and sand is filtered and then sucked into the equipment room to form air circulation.

The filtered gas can be discharged through the exhaust pipe. In this process, the driving motor will drive the cleaning ring to rotate at the bottom of the filter disc, and clean the sand particles to the periphery of the bottom of the filter disc, and then fall into the collection bucket by gravity. If the filter bag is blocked, you only need to close the first valve on the corresponding first connecting pipe, so that the filter bags inside the first mounting shell and the second mounting shell can be used alternately, and the dust extraction component can be used to clean the sand inside the filter bag that needs to be cleaned. Through this structure, the filtration effect is improved through triple filtration of cyclone filtration, filter disc and filter bag, and the probability of blockage is reduced by alternating use of the cleaning ring and two filter bags during the filtration process, which is also convenient for cleaning the blocked sand.
