Description

Technical Field

[0001] The present application relates to the field of bag cleaning, and in particular to a bag cleaning device for pulse-type bag dust removal. Background Art

[0002] A pulse bag filter is a highly efficient dry dust removal device that primarily removes dust particles from dust-laden air through filtration. Its core component is the filter bag, which separates dust from air through its filtering action. Dust-laden air first enters the dust collector through the air inlet. A flow guide distributes the air evenly around each filter bag. As the dust-laden air passes through the filter bag, dust particles are trapped on its outer surface, while clean air passes through and into the interior. As dust accumulates on the bag surface, it increases resistance to air flow. When this resistance reaches a certain level, the filter bag needs to be cleaned.

[0003] Pulse cleaning is its main cleaning method. The pulse airflow generated by compressed air instantly blows the filter bag, causing the filter bag to vibrate and reverse airflow, shaking off the dust attached to the outer surface of the filter bag into the ash hopper, thereby restoring the filtering performance of the filter bag. The bag-cleaning cannon is a device for cleaning the cloth bag. It mainly removes dust on the surface of the cloth bag by instantly releasing compressed air or other gases to generate a strong impact force. When in use, the muzzle of the cannon needs to be inserted into the opening of the cloth bag, but there is a certain gap between the inserted cloth bag cleaning cannon and the cloth bag opening. When blowing, the impact force of the compressed air will blow some dust out of the gap, thereby causing certain dust pollution to the surrounding operating environment, distributing the dust around the cloth bag collector, and having a certain impact on the overall cleaning efficiency of the cloth bag.

[0004] In view of the above-mentioned related technologies, the inventor believes that the bag-type dust cleaning cannon has the defect of dust being ejected outward along the gap between the equipment and the bag when in use. Therefore, a bag cleaning device for pulse bag dust removal is proposed to solve the above problem. Utility Model Content

[0020] The following is combined with Figure 1-5 This application is described in further detail.

[0021] The present application discloses a bag cleaning device for pulse bag dust removal.

A plurality of support members 5 are fixedly installed at the bottom end of the support ring plate 6, and the support ring plate 6 is located in the middle position below the air jet nozzle 4. A damping sleeve 7 is provided on the outer surface of the air jet nozzle 4 through a damping bearing sleeve. A fixed groove is opened on one side of the outer surface of the air jet nozzle 4, and the top of the inner wall of the damping sleeve 7 A damping sleeve is provided, and the fixed groove and the damping bearing are adapted to each other. A plurality of fixed grooves 8 are opened on the outer surface of the damping sleeve 7, and a movable support rod 9 is rotatably installed inside the fixed groove 8. A dustproof cloth belt 10 is fixedly connected between two adjacent movable support rods 9. A movable connecting rod 11 is hinged to the top of the movable support rod 9 near the hinge axis through the bearing seat. A plurality of fixed guide rails 12 are welded at the outer surface of the damping sleeve 7 and the corresponding position of the fixed groove 8. A movable plate 13 is movably installed inside the fixed guide rail 12, and a connecting plate 14 is symmetrically welded to the bottom of the movable plate 13. The connecting plate 14 and the movable connecting rod 11 are rotatably connected.

[0022] After the dust bag 2 is in the air, the dust collector 1 is lifted up and the dust bag 2 is in the air. When the dust bag 2 is in the air, the dust collector 1 is lifted up and the dust bag 2 is in the air. When the dust bag 2 is in the air, the dust bag 2 is lifted up and the dust bag 2 is in the air. When the dust bag 2 is in the air, the dust bag 2 is lifted up and the dust bag 2 is in the air.

[0023] Reference Figure 2 and Figure 3 The top of multiple movable plates 13 is placed on the outer surface of the air jet nozzle 4 and is welded with a connecting sleeve 15. A number of fixing rods 16 are welded to the edge of the top of the connecting sleeve 15. The top of the fixing rod 16 is placed on the outer surface of the bag-cleaning cannon 3 and is welded with an outer sliding sleeve 17. The outer surface of the bag-cleaning cannon 3 is fixedly connected with fixed baffles 18 in parallel up and down. One side of the outer surface of the fixing rod 16 passes through the middle position of the fixed baffle 18 and is welded with a limiting card 19. The outer surface of the fixing rod 16 is located between the fixed baffle 18 and the limiting card 19 and is sleeved with a spring 20. A through hole is opened in the middle of the top of the fixed baffle 18. The outer diameter of the fixing rod 16 is smaller than the inner diameter of the through hole, and the fixing rod 16 and the through hole are fitted with each other.

[0024] By pulling the outer sliding sleeve 17 upward along the bag cleaning cannon 3, the outer sliding sleeve 17 drives the multiple fixed rods 16 to move synchronously, and drives the spring 20 to contract, so that the fixed rods 16 and the limit card 19 move downward under the elastic force of the spring 20, and then the multiple movable support rods 9 drive the dustproof belt 10 to be retracted. The overall opening and closing of the dustproof belt 10 is controlled by the movable outer sliding sleeve 17, which reflects the regulating effect of the outer sliding sleeve 17 on the dustproof belt 10.

[0025] The implementation principle of the pulse-type bag-type dust collector of the present application is as follows: by inserting the air jet nozzle 4 at the bottom end of the bag-type dust cleaning gun 3 into the dust cleaning bag 2, the support member 5 cooperates with the support ring plate 6 to support the bag-type dust collector 1, and pulls the damping sleeve 7 to move downward along the outer surface of the air jet nozzle 4 to extend to the bottom of the support ring plate 6, and pulls the outer sliding sleeve 17 to move upward along the bag-type dust cleaning gun 3, so that the outer sliding sleeve 17 drives multiple fixed rods 16 to move synchronously, and drives the spring 20 to contract, so that the connecting sleeve 15 moves synchronously with the fixed rod 16 to drive multiple movable plates 13 to rise along the inside of the fixed guide rail 12, so that the movable movable plate 13 and the connecting plate 14 drive the movable connecting rod 11 to rotate, thereby making multiple movable plates 13 move upward. The connecting rod 11 drives multiple movable support rods 9 to rotate and unfold synchronously, opening the retracted dust-proof cloth belt 10 to protect the top opening of the cleaning bag 2, so that the edge of the dust-proof cloth belt 10 abuts against the inner wall of the cleaning bag 2, thereby blocking the gap between the cleaning bag 2 and the bag-cleaning cannon 3, so that the bag-cleaning cannon 3 injects compressed air into the cleaning bag 2 through the jet nozzle 4 to clean the dust; compared with the existing technology, this solution has the effect of facilitating the resistance against dust blown up by the bag-cleaning cannon 3 when in use, reduces the splashing effect of dust from the cleaning bag 2, solves the problem of dust spreading outward from the gap between the bag-cleaning cannon 3 and the cleaning bag 2, and improves the sealing effect of the movable connecting rod 11 on the opening of the cleaning bag 2.
