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] The pulse bag dust collector is a dust removal device that uses pulse jet cleaning technology. It is mainly composed of a box, filter bags, a jet system, a control system, and other parts. When working, the dust-laden gas enters the box from the air inlet of the dust collector. When passing through the filter bag, the dust is trapped on the outer surface of the filter bag, and the purified gas enters the air outlet through the filter bag and is discharged. As the dust on the surface of the filter bag continues to accumulate, the resistance of the dust collector gradually increases. At this time, the control system will start the jet system and spray high-pressure air into the filter bag through the pulse valve, causing the filter bag to expand instantly and shake off the dust on the surface of the filter bag to achieve the purpose of cleaning.

[0003] In the prior art, pulse bag dust collectors are fixed when installing bags. After each pulse, the dust on the inner wall of the bag is blown away, but at the same time, the dust is stuck in the gaps of the bag by the impact force. If it is a horizontal pulse, the dust is easy to accumulate and clog one side of the bag. For this reason, the present invention provides a pulse 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 technical solution of the present invention is: a pulse bag dust collector comprises an inner discharge port, the outer side of the inner discharge port is rotatably connected with an outer adjustment ring, the inner side of the outer adjustment ring is fixedly connected with an adjustment ball, the outer side of the inner discharge port is provided with a corrugated groove, the adjustment ball is slidably connected in the corrugated groove, the top angles of the corrugated grooves are the same, the bottom angles of the corrugated grooves are the same, and the number of the top angles and the bottom angles are the same, there is an inner folding angle at the connection of the top angles, there is an inner folding angle at the connection of the bottom angles, the top angle of the corrugated groove and the corresponding bottom inner folding angle are both offset to the right, and the top inner folding angle of the corrugated groove and the corresponding bottom angle are both offset to the left, the outer side of the inner discharge port is fixedly connected with a mounting top ring, the bottom of the mounting top ring is fixedly connected with a telescopic outer cylinder, the inner side of the telescopic outer cylinder is slidably connected with a telescopic inner column, a telescopic spring is installed inside the telescopic outer cylinder, the two ends of the telescopic spring are respectively fixedly connected to the mounting top ring and the telescopic inner column, the bottom of the telescopic inner column is fixedly connected with a connecting bottom ring, and the rotation of the connecting bottom ring is connected to the outer When the pulse is applied, the outer adjusting ring is pulled upward by the force of the pulse so that the adjusting ball moves downward relative to the inner discharge port. When the bottom inclined surface is touched, 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 inner side of the bottom angle. The telescopic spring pulls the outer adjusting ring upward. Because the top inner angle is on one side of the bottom angle, the adjusting ball moves vertically upward and moves to an adjacent top angle inclined surface at the beginning. The adjusting ball is pushed by the inclined surface to be connected to the inner side of the initially adjacent top angle, so that the outer adjusting ring rotates at a certain angle, and the bag rotates at 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 outer ring of the sliding sleeve is fixedly connected to the sliding sleeve of the sliding sleeve, and the inner ring of the sliding sleeve is fixedly connected to the inner ring of the sliding sleeve. The outer ring of the sliding sleeve is fixedly connected to the outer ring of the sliding sleeve, and the outer ring of the sliding sleeve is fixedly connected to the inner ring of the sliding sleeve. The connecting slider is slidably engaged with the inner side of the sliding groove, and the bottom of the connecting slider is fixedly connected with a fixing clamping ring, and the fixing clamping ring is movably sleeved on the outer side of the fixed pulling column, and the outer side of the connecting inner ring is sleeved with a dust bag, and the adjacent side of the fixed inner ring and the fixed outer ring are mutually fitting curved surfaces; when in use: the cloth bag mouth enters from the inner side of the fixed outer ring, and sleeves on the outer side of the fixed inner ring, so that the mouth is wrapped around the outer side of the connecting inner ring, and then the connecting straight column is pulled upward to make the fixed pulling column and the center of the fixed clamping ring flush with each other. At the same time, the fixing buckle is pulled to make the inner slider move along the circular groove, squeeze the fixing spring, and pull the connecting slider outward. When the fixed pulling column and the center of the fixed clamping ring are flush, the sealing disk is released, and the fixing clamping ring is pushed by the fixing spring to be sleeved on the outer side of the fixed pulling column, and the fixed outer ring squeezes the cloth bag, so that the cloth bag is fixed between the fixed inner ring and the fixed outer ring. At the same time, during pulsing, the fixed pulling column is perpendicular to the pulse direction and the fixing clamping ring will not be detached.

[0008] The first one is that the pulse bag dust collector described in the present invention has an inner discharge port installed on the outer side of the pulse port, and the bag is fixed on the outer side of the outer adjustment ring. Initially, the telescopic spring contracts and pulls up, pulling the connecting bottom ring upward, pulling the outer adjustment ring upward, and the internal adjustment ball passes through the inclined surface of the top angle upward, so that the adjustment ball is against a top angle. When the pulse is performed, the outer adjustment ring is pulled downward as a whole by the driving force of the pulse, so that the adjustment ball moves downward relative to the inner discharge port. When the bottom inclined surface is touched, the adjustment ball is pushed by the inclined surface to rotate the outer adjustment ring. When the pulse impact is completed, the adjustment ball is on the inner side of the bottom angle, and the telescopic spring pulls the outer adjustment ring upward. Because the top inner angle is on one side of the bottom angle, the adjustment ball moves vertically upward and moves to an initially adjacent top angle inclined surface. The inclined surface pushes the adjustment ball to be clamped inside the initially adjacent top angle, so that the outer adjustment ring rotates at 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.

[0009] Second: The pulse bag dust collector described in the present invention is to allow the bag mouth to enter from the inner side of the fixed outer ring, and sleeve on the outer side of the fixed inner ring so that the mouth is wrapped around the outer side of the connecting inner ring. Then, the connecting straight column is pulled upward to make the fixed pull column and the center of the fixed clamping ring flush. At the same time, the fixed buckle is pulled to move the inner slider along the circular groove, squeezing the fixed spring to pull the connecting slider outward. When the fixed pull column and the center of the fixed clamping ring are flush, 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. At the same time, the fixed outer ring squeezes the bag so that the bag is fixed between the fixed inner ring and the fixed outer ring. At the same time, when pulsating, the fixed pull column is perpendicular to the pulse direction and the fixed clamping ring will not be detached.

[0010] Summary: The pulse bag dust collector described in the present invention has excellent filtering ability and is suitable for a variety of industrial occasions. Its innovation lies in the unique pulse spraying 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.
