Description

Technical Field

[0001] The invention relates to the technical field of dust removal, in particular to a pulse bag dust collector. Background Art

[0002] A pulse bag dust collector utilizes pulse jet cleaning technology. It primarily consists of a dust collector housing, filter bags, a jet system, and a control system. During operation, dust-laden air enters the dust collector through the air inlet. As it passes through the filter bags, dust is trapped on their outer surfaces. The purified air then flows through the bags and into the air outlet for discharge. As dust accumulates on the filter bag surface, the dust collector's resistance gradually increases. At this point, the control system activates the jet system, injecting high-pressure air into the filter bags through a pulse valve. This causes the bags to expand instantly, shaking off dust from the surface and achieving the desired cleaning effect.

[0003] In the prior art, pulse-type bag dust collectors are all fixed when installing bags. After each pulse, the dust on the inner wall of the bag is blown away, but at the same time, some dust is stuck in the gaps of the bag due to the impact force. If the pulse is horizontal, the dust is likely to accumulate and clog one side of the bag. For this reason, the present invention provides a pulse-type bag dust collector. Summary of the Invention

[0004] The object of the present invention is to provide a pulse bag dust collector to solve the problems raised in the above background technology.

[0005] The cam is fixedly provided with an adjusting screw mandrel on the outside of the cam, and the adjusting screw mandrel is fixedly provided with an adjusting screw mandrel on the inside of the cam. When the pulse is in progress, the outer adjusting ring is pulled upward by the contraction spring, and the bottom connecting ring is pulled upward, and the outer adjusting ring is pulled upward. The inner adjusting ball passes through the inclined surface of the top angle, so that the adjusting ball rests on a top angle. When the pulse is in progress, the outer adjusting ring is pulled downward as a whole by the driving force of the pulse, so that the adjusting ball moves downward relative to the inner discharge port. When it touches the bottom inclined surface, the adjusting ball is pushed by the inclined surface to rotate the outer adjusting ring. When the pulse impact is completed, the adjusting ball is on the inside of the bottom angle, and the contraction spring pulls the outer adjusting ring upward. Because the top inner corner is on one side of the bottom angle, the adjusting ball is vertically upward and will move to the inclined surface of the initially adjacent top angle. The inclined surface pushes the adjusting ball to the inside of the initially adjacent top angle, so that the outer adjusting ring rotates a certain angle, so that the center of gravity of the pulse impact of the bag is different each time, so that the dust will not accumulate in one place of the bag.

[0006] The top of the connecting straight column is fixedly connected to the fixed pull column, the outer side of the inner sliding shaft is fixedly connected to the connecting slider, and the bottom of the circular groove is communicated with the sliding groove. When the locking cam is engaged, the locking cam is engaged with the locking cam and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam,

[0007] The present invention provides a pulse bag dust collector through improvement, which has the following improvements and advantages compared with the prior art:

[0008] When the bag is in a state of being moved downwards, the outer ring is pressed against the outer edge of the bag and the adjusting ball is pressed against the adjusting ball, and the adjusting ball is pressed against the adjusting ball. When the bag is in a state of being moved downwards, the adjusting ball is pressed against the adjusting ball, and the adjusting ball is pressed against the adjusting ball. When the bag is in a state of being moved upwards, the adjusting ball is pressed against the adjusting ball, and the adjusting ball is pressed against the adjusting ball. When the bag is in a state of being moved upwards, the adjusting ball is pressed against the adjusting ball, and the adjusting ball is pressed against the adjusting ball. When the bag is in a state of being moved upwards, the adjusting ball is pressed against the adjusting ball, and the adjusting ball is pressed against the adjusting ball. When the bag is in a state of being moved upwards, the adjusting ball is pressed against the adjusting ball, and the adjusting ball is pressed against the adjusting ball.

[0009] Second: The pulse bag dust collector described in the present invention has the bag opening entering from the inner side of the fixed outer ring, sleeved on the outer side of the fixed inner ring, so that the opening is wrapped around the outer side of the connecting inner ring, and then the connecting straight column is pulled upward to make the fixed pull column flush with the center of the fixed clamping ring, and at the same time, the fixed pull buckle is pulled to move the inner slider along the circular groove, squeezing the fixed spring to pull the connecting slider outward, and when the fixed pull column is flush with the center of the fixed clamping ring, the sealing disk is released, and the fixed clamping ring is pushed by the fixed spring to be sleeved on the outer side of the fixed pull column, and at the same time, the fixed outer ring squeezes the bag to fix the bag between the fixed inner ring and the fixed outer ring, and at the same time, the fixed pull column is perpendicular to the pulse direction during pulsing, and the fixed clamping ring will not be detached;

Its innovation lies in the unique pulse jet technology, which effectively removes dust accumulated on the filter bag and makes the bag rotate with the thrust of the pulse, thereby preventing dust from accumulating in one place.
