Description

Technical Field

[0001] The utility model belongs to the field of dust collectors, and in particular relates to a pulse bag type dust collector. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The most commonly used type in industry is the bag-type dust collector. The bag-type dust collector uses the filtering effect of fiber fabric to filter the dust-containing gas to purify the gas. At the same time, because the filter bag filters the gas for a long time, a layer of dust will adhere to the surface of the filter bag. At this time, the dust accumulated on the surface of the filter bag needs to be cleaned.

[0003] A Chinese patent with publication number CN217163564U discloses a pulse bag dust collector, comprising a box body, which is divided into an exhaust chamber and a filter chamber by a partition, an ash hopper is connected to the bottom of the box body, and an ash discharge port is provided at the bottom of the ash hopper; an exhaust port is provided on the side of the exhaust chamber, an exhaust fan is provided at the exhaust port, an annular pipe is provided on the outside of the box body, an air outlet extending into the filter chamber is provided on the annular pipe, an air inlet pipe is also provided on the annular pipe, and a filter assembly is provided on the partition; an air distribution box is provided in the exhaust chamber, the air distribution box is connected to the air bag through a connecting pipe, a pulse valve is provided on the connecting pipe, and a plurality of outlets are provided at the bottom of the air distribution box; a guide rod is provided in the filter chamber, a slide plate is provided on the guide rod for sliding, a screw rod screwed to the slide plate is provided for rotation in the filter chamber, the screw rod is driven to rotate by a servo motor arranged outside the box body, and a paddle for the filter assembly is connected to the slide plate through a spring.

[0004] A pulse bag dust collector in the above-mentioned comparative document is driven by a servo motor to make the paddle beat the filter component to achieve cleaning. The paddle beating the filter component is likely to cause damage to the filter bag. Secondly, the beating cleaning method can only clean the dust on the surface of the filter bag, and the cleaning effect is not good.

[0005] In view of this, the present utility model is proposed. Utility Model Content
