Description

Technical Field

[0001] The invention relates to the technical field of pulse bag dust collectors, and in particular to a pulse bag dust collector and a use method thereof. Background Art

[0002] The pulse bag dust collector is a high-efficiency dust removal equipment that is improved on the basis of the traditional bag dust collector. It retains the advantages of the traditional bag dust collector, such as high purification efficiency, strong gas processing capacity, stable performance, convenient operation, long filter bag life, and small maintenance workload. The pulse bag dust collector removes dust on the filter bag by spraying compressed air into the filter bag. When the dust-laden gas enters the filter bag, most of the dust is intercepted and adsorbed on the filter bag, while the fine dust passes through the filter bag and enters the ash hopper. When the dust on the filter bag accumulates to a certain extent, the cleaning system starts to work;

[0003] When a certain amount of dust accumulates on the filter bags in the pulse bag dust collector, the cleaning system is started to operate. The current cleaning system generally uses air pressure to clean the dust on the surface of the filter bags. However, when the air pressure gradually flows downward, the impact force will gradually decrease with the increase of the moving distance, resulting in the pressure becoming smaller when the air pressure contacts the lower end of the filter bag, causing some dust to remain at the lower end of the filter bag, affecting the working efficiency of the filter bag.

[0013] Furthermore, the number of the movable rings is two, and the two movable rings are symmetrically arranged with the fixed plate as the center, and the surface of the movable ring is in contact with the inner wall of the dust collector. The number of the positioning rings is several, and the end of the cleaning plate extends to the interior of the positioning ring, and the filter bag is located inside the positioning ring, and the end of the cleaning plate is in contact with the surface of the filter bag, and the mounting frame is located at the lower interior of the dust collector.

After entering the dust collector, the air will pass through the filter bag and enter the air outlet pipe for discharge. The dust in the air will be adsorbed on the surface of the filter bag. A positioning frame is provided inside the filter bag to support the filter bag.

[0022] S2: When the lifting plate moves, it pushes the moving ring to slide on the inner wall of the dust collector through the bent plate. When the moving ring moves, it drives the positioning ring to move on the surface of the filter bag through the fixed plate. When the positioning ring moves, it pushes the cleaning plate to clean the surface of the filter bag.

[0023] S3: When the vertical rod moves, it drives the inclined plate to move through the cylindrical rod. When the inclined plate moves, it pushes the inclined plate to move inside the filter bag.

[0024] S4: The inclined spring piece moves inside the round hole rod through the round rod and generates friction with the tooth plate. The friction between the inclined spring piece and the tooth plate generates vibration, which is transmitted to the cleaning plate through the bent plate.

[0025] The present invention has the following beneficial effects:

[0026] The dust particles in the air are then passed through the filter bag and are then passed through the filter bag into the outlet pipe for further use.

[0027] The present invention starts the electric push rod to push the lifting plate to move. When the lifting plate moves, it pushes the moving ring to slide on the inner wall of the dust collector through the bent plate. When the moving ring moves, it drives the positioning ring to move on the surface of the filter bag through the fixed plate. When it moves, the positioning ring pushes the cleaning plate to clean the surface of the filter bag, thereby preventing dust from accumulating on the surface of the filter bag and affecting the filtration efficiency. The cleaning plate is pushed up and down on the surface of the filter bag by the electric push rod, and the dust on the surface of the filter bag is quickly cleaned by the cleaning plate, thereby improving the working efficiency of the filter bag.

[0028] When the movable ring of the present invention moves, the circular frame is pushed to move synchronously through the connecting rod. When the circular frame moves, the vertical rod is driven to move through the synchronous frame. When the vertical rod moves, the inclined plate is driven to move through the cylindrical rod. When the inclined plate moves, it pushes the inclined plate to move inside the filter bag. When the inclined plate moves, it pushes the inclined plate to expand through the friction force with the filter bag. When the inclined plate expands, it squeezes the filter bag to expand through the inclined plate. The expansion of the filter bag can expose dust in the surface gaps to prevent dust from being stuck inside the filter bag.

[0029] When the bent plate of the present invention moves, the inclined spring piece is driven to move through the round rod. The inclined spring piece moves inside the round hole rod through the round rod and generates friction with the tooth plate. The friction between the inclined spring piece and the tooth plate generates vibration, which is transmitted to the cleaning plate through the bent plate. When the inclined plate squeezes the filter bag to expand, the dust in the gap of the filter bag will fall off through the vibration, thereby improving the cleaning effect of the filter bag.

9. The method for using a pulse bag dust collector according to claim 8, characterized in that: The following steps are involved: S1: Air containing dust will enter the interior of the dust collector (1) through the air inlet pipe (3). After entering the interior of the dust collector (1), the air will enter the air outlet pipe (2) through the filter bag (8) and be discharged. The dust in the air will be adsorbed on the surface of the filter bag (8). A positioning frame (10) is provided inside the filter bag (8), and the positioning frame (10) is used to support the filter bag (8); S2: When the lifting plate (24) moves, it pushes the moving ring (21) to slide on the inner wall of the dust collector (1) through the bent plate (28); when the moving ring (21) moves, it drives the positioning ring (22) to move on the surface of the filter bag (8) through the fixed plate (20); when the positioning ring (22) moves, it pushes the cleaning plate (23) to clean the surface of the filter bag (8); S3: When the vertical rod (33) moves, it drives the inclined plate (36) to move through the cylindrical rod (34), and when the inclined plate (36) moves, it pushes the inclined plate (35) to move inside the filter bag (8), and when the inclined plate (35) moves, it pushes the inclined plate (36) to expand through the friction force with the filter bag (8); S4: The inclined spring piece (42) moves inside the round hole rod (44) through the round rod (40) and generates friction with the tooth plate (43).
