The dust collector drives the blades to rotate at a high speed by using the motor, and generates air negative pressure in the sealed shell to absorb dust. The existing industrial dust collector mainly depends on a filter cloth bag arranged in the industrial dust collector to filter and remove dust, and filtered air is exhausted by a vacuum pump. However, in the case of long-term use of the cloth bag type dust collector, the cloth bag is quickly full of dust, so that the cloth bag is blocked, and the dust collection effect is affected. In order to solve the problem, the traditional method adopts two modes of manual dust vibration and pulse cleaning.

When the second dust collecting bucket 30 is full of dust collecting bags, the dust collecting bags need to be replaced, the second dust collecting bucket 30 connected with the second filter bucket 33 is pulled out to replace the dust collecting bags, and the second dust collecting bucket can be installed again by reversing operation after the replacement is finished.
The working principle of the first filter barrel 9 for cleaning ash and the second filter barrel 33 for absorbing dust is as follows: the PLC controls to close the third valve 131, open the fifth valve 32, operate the second fan 36, close the sixth valve 34, open the fourth valve 12, open the first valve 17, the second valve 18 and the seventh valve 5, blow the compressed air in the air storage device 14 to the lower part of the partition plate 23 through the second blowback pipe 26, and blow the compressed air through the periphery of the filter bag 243; the first blowback pipe 25 blows towards the inside of the filter bag to blow back the inside of the filter bag 243; the first blowing pipe 4 blows into the first blowback exhaust pipe 27, the dust on the periphery of the filter bag 243 is removed by high air pressure, the dust falls into the first dust collecting barrel 29, the external dust enters the lower cavity of the second partition plate 45 through the air suction port 13 and is then filtered by the filtering device 24, the dust temporarily stays in the second filter barrel 33, the fresh air passes through the annular hollow sleeve 241 and then enters the upper cavity of the second partition plate 45, the fresh air enters the second air outlet pipe 35 through the upper cavity of the second partition plate 45 and then enters the second fan 36, and the fresh air is discharged to the muffler through the second fan air outlet 37. When the first dust collecting bucket 29 is full of dust collecting bags, the dust collecting bags need to be replaced, the first dust collecting bucket 29 connected with the first filter bucket 9 is pulled out to replace the dust collecting bags, and the dust collecting bags can be installed again by reversing operation after replacement.
When the first filtering barrel 9 is back-blown and cleaned, the second filtering barrel 33 is seamlessly jointed with the first filtering barrel 9 to work. At this time, the second fan 36 takes over the first fan 21 to work at the same time, so that dust collection is not affected, when the reverse blowing is completed and the first fan 21 can continue to work, the sixth valve 34 is opened, and dust drops in the second filter vat 33.
