Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and more specifically, it relates to an anti-blocking dust removal filter bag. Background Technique

[0002] A dust remover is a common filtering device used to process the flue gas generated in industrial production, filter the dust in the gas, discharge the purified gas, and ensure the air environment. The filter bag is the main functional structure of the filter.

[0003] When the dust removal equipment is working, the gas will flow through it internally and be filtered through the filter bag. When the gas passes through the filter bag, the dust in the gas will be blocked by the bag body, thereby providing the gas filtration effect. However, as the work progresses, the dust is likely to adhere to the surface of the bag body. As the working time becomes longer, the dust is likely to block the bag body, affecting the normal operation of the equipment. Therefore, workers need to maintain the dust removal equipment. They need to stop the equipment and disassemble it, remove the internal bag body, and clean the surface. The operation amount of the workers is large, and a lot of working time will be wasted. In addition, some dust removal equipment uses the backflush of the gas to clean the bag body, but the general gas outlet position is far from the bag body, and the impact on the edge of the bag body is low, and the cleaning effect is limited.

[0042] Specifically, through the support of the support ring 17, the support rod 18 is located inside the bag body 1. The support rod 18 supports the bag body 1 to a certain extent to ensure the relative stability of the shape of the bag body 1 during operation and prevent it from floating randomly with the gas.

[0043] Please refer to Figure 2 、 Figure 5 and Figure 7 , as a further implementation of the sliding frame: the support ring 17 is rotationally matched with the sliding frame 3. A transmission shaft 19 is provided on the sliding frame 3. Transmission wheels 20 are provided at both ends of the transmission shaft 19. The transmission wheels 20 cooperate with the support ring 17 and the rotating ring 8. The output end of the second drive motor 7 is provided with a driving wheel 21, and the driving wheel 21 cooperates with the transmission wheel 20.

[0044] Specifically, when the second driving motor 7 provides power, it drives the corresponding transmission wheel 20 to rotate through the driving wheel 21. The transmission wheel 20 will drive the transmission shafts at both ends to rotate through the conduction of the transmission shaft 19, thereby driving the corresponding support rings 17 and rotating rings 8 to rotate, and enabling the support rods 18 and the cleaning scrapers 10 to move synchronously, ensuring stable cooperation.

[0045] Please refer to Figure 5 , as a further implementation of the support rod: a roller groove 22 is provided on the support rod 18, and a pressing roller 23 is rotatably connected in the roller groove 22, and the pressing roller 23 cooperates with the cleaning scraper 10.

[0046] Specifically, the pressing roller 23 can rotate in the roller groove 22 to press against the bag body 1 in contact, and cooperate with the cleaning scraper 10. When moving, through the rotation of the pressing roller 23, the pressing on the bag body 1 is ensured to be stable.

[0047] Please refer to Figure 4 and Figure 5 , as a further implementation of the sliding frame: a protective shell 24 is provided at the lower end of the sliding frame 3, and the protective shell 24 cooperates with the transmission wheel 20 and the rotating ring 8.

[0048] Specifically, the protective shell 24 covers the mating part of the lower transmission wheel 20 and the rotating ring 8 to protect the mating part and prevent the mating of the transmission wheel 20 and the rotating ring 8 from being affected by dust.

[0049] Please refer to Figures 1-3 , as a further implementation of the sliding frame: a sliding opening 25 is provided on the mounting plate 2, the sliding frame 3 is slidably matched with the sliding opening 25, sealing sliding plates 26 are provided at both ends of the sliding frame 3, and sealing sliding grooves 27 are provided in the sliding opening 25, and the sealing sliding plates 26 are slidably matched with the sealing sliding grooves 27.

[0050] Specifically, when the sliding frame 3 moves in the sliding opening 25, it will drive the sealing sliding plates 26 to move, so that the sealing sliding plates 26 slide in the sealing sliding grooves 27. Through the cooperation of the sealing sliding plates 26 and the sealing sliding grooves 27, the sealing effect is maintained. Thus, when the sliding frame 3 moves, it also cooperates with the sealing sliding plates 26 to block the sliding opening 25, preventing gas from passing through the sliding opening 25 from structures other than the bag body 1.

[0051] In summary, when the overall equipment is in use (or running):

[0052] When the device is working, connect the device to an external power supply. Install the bag body 1 on the sliding frame 3. During operation, the bag body 1 provides a filtering effect. When performing the filtering operation, control the first driving motor 4 to work. The first driving motor 4 provides power to drive the eccentric wheel 5 to rotate. The eccentric wheel 5 drives the sliding frame 3 to move through the transmission rod 6, causing the sliding frame 3 to move repeatedly along the mounting plate 2, thereby driving the bag body 1 to vibrate and shake off the dust attached to the bag body 1. Moreover, when the sliding frame 3 moves within the sliding opening 25, it will drive the sealing slide plate 26 to move, causing the sealing slide plate 26 to slide within the sealing chute 27. Through the cooperation of the sealing slide plate 26 and the sealing chute 27, the sealing effect is maintained. Thus, when the sliding frame 3 moves, it also cooperates with the sealing slide plate 26 to block the sliding opening 25 and prevent gas from passing through the sliding opening 25 from structures other than the bag body 1.

[0053] When the dust attached to the bag body 1 is stubborn and cannot be cleaned only by vibration, control the second driving motor 7 to work. The second driving motor 7 provides power to drive the corresponding transmission wheel 20 to rotate through the driving wheel 21. The transmission wheel 20 will drive the transmission wheels 20 at both ends to rotate together through the transmission of the transmission shaft 19, thereby driving the corresponding support ring 17 and the rotating ring 8 to rotate. With the support of the support ring 17, the support rod 18 is located inside the bag body 1. The support rod 18 supports the bag body 1 to a certain extent to ensure the relative stability of the shape of the bag body 1 during operation and prevent it from floating randomly with the gas. The cleaning rod 9 is driven to move by the rotating ring 8, causing the cleaning rod 9 to drive the cleaning scraper 10 to rotate around the bag body 1. Under the drive of the same driving device, the support rod 18 and the cleaning scraper 10 move synchronously to ensure the stability of the cooperation. The pressure roller 23 rotates within the roller groove 22 and presses against the bag body 1 in contact, cooperating with the cleaning scraper 10 to ensure that the cleaning scraper 10 stably contacts the surface of the bag body 1. Thus, when the cleaning scraper 10 rotates around the bag body 1, the dust on the surface of the bag body 1 is cleaned by the cleaning scraper 10. In addition, the cooperation part of the transmission wheel 20 and the rotating ring 8 at the lower end is covered by the protective shell 24 to protect the cooperation and prevent the cooperation of the transmission wheel 20 and the rotating ring 8 from being affected by dust.

[0054] In addition, connect the air supply hose 14 to the air supply device. During the interval when the dust removal device is working, further clean the dust on the filter bag. Pass gas into the air supply hose 14. Under the guidance of the air supply hose 14, the gas flows into the air outlet pipe 12 and sprays out along the air outlet 13. The air outlet 13 faces the inside of the bag body 1 to blow the bag body 1 in the opposite direction. Moreover, under the support of the support frame 11, control the driving push rod 15 to work, causing the driving push rod 15 to drive the movable frame 16 to move. The movable frame 16 drives the air outlet pipe 12 to move, causing the air outlet pipe 12 to move up and down to discharge air more evenly and blow off the dust adsorbed on the bag body 1.
