Description

Technical Field

[0001] This utility model belongs to the technical field of bag dust collectors, specifically a bag dust collector. Background Technology

[0002] Existing baghouse dust collectors consist of a dust collector housing with a partition inside. The partition divides the inner cavity of the dust collector housing into a lower inlet chamber and an upper outlet chamber. The lower end (open end) of the filter bag is connected to the partition, and the upper end of the filter bag is connected to a support shaft located in the outlet chamber. Dust-laden air enters the inlet chamber and then enters the filter bag. After being filtered by the filter bag, the cleaner air enters the outlet chamber and is discharged from the outlet chamber. The filter bag needs to be cleaned after a period of use to avoid affecting the normal operation of the baghouse dust collector.

[0003] A Chinese patent with authorization announcement number CN203842427U discloses a bag filter dust collector, belonging to the field of dust removal technology: it provides a bag filter dust collector with a simple structure, automatic dust collection, and dust that does not easily accumulate on the dust collector bag, making the dust collector bag safer and more reliable; a bag filter dust collector with a dust collector bag inside the dust collector body and a swing device on the upper part of the dust collector body: this utility model is mainly used in dust removal.

[0004] However, the above solution still has some problems. When the spring vibrates, the dust collector bag bounces repeatedly, and the dust is scattered outward by the elastic force, causing the dust collector to be filled with dust again. Therefore, the dust collector bag has a poor cleaning effect. In order to solve the above problems, a bag dust collector is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a bag filter dust collector.

[0006] The technical solution adopted by this utility model to solve its technical problem is a bag filter dust collector, including: a dust collector body, a dust collector bag disposed inside the dust collector body, drive motors symmetrically arranged inside the dust collector body, a threaded rod fixedly connected to the output end of the drive motor, a sensor disposed inside the dust collector body, an adjusting block threadedly connected to the threaded rod, a hollow frame fixedly connected to one side of the adjusting block, a fan fixedly connected to the upper surface of the hollow frame, the sensor electrically connected to the fan, an exhaust port disposed on the fan, a duct fixedly connected to the output end of the fan, the duct fixedly connected inside the hollow frame, a suction pipe disposed on the duct, a dustproof net fixedly connected to the inner wall of the hollow frame, a dust discharge port opened at the bottom of the hollow frame, the sensor located below the adjusting block, the threaded rod rotatably connected inside the dust collector body, two sets of hollow frames respectively located on both sides of the dust collector bag, and the air drawn in by the fan is discharged outward through the exhaust port, thereby avoiding affecting the normal operation of the fan.

[0007] Preferably, a dust inlet is fixedly connected to one side of the dust collector body, and a clean air outlet is provided on one side of the dust collector body. An anti-slip ring is fixedly connected to the dust inlet, and the anti-slip ring extends to the outside of the dust inlet. The anti-slip ring can increase the friction with the surface of the dust transmission pipe, thereby improving its fixing strength.

[0008] Preferably, a reinforcing ring is fixedly connected to the anti-slip ring, and a reinforcing bolt is threaded onto the reinforcing ring. A dust outlet is fixedly connected to the bottom of the dust collector body, and a dust collection box is provided below the dust outlet. The reinforcing bolt is used to connect to the opening of the reinforcing ring, and the ring size can be adjusted by rotating the reinforcing bolt.

[0009] Preferably, a door is hinged to one side of the dust collection box, and a water pipe is fixedly connected to the outside of the dust collection box. A connecting pipe is provided on the water pipe, and the water pipe is fixedly connected to the inside of the support leg of the dust collector body. The water pipe is connected to the dust collection box and the support leg of the dust collector body, thereby ensuring the stability of the water pipe during use.

[0010] Preferably, the water pipe is equipped with a mist spray head, which is fixedly connected to the inside of the dust collection box. An electric telescopic rod is fixedly connected to one side of the dust collection box, and a pusher plate is fixedly connected to the telescopic end of the electric telescopic rod. When the electric telescopic rod is in motion, it can drive the pusher plate to move into the dust collection box.

[0011] Preferably, the pusher plate is movably connected to the inside of the dust collection box, and the bottom of the pusher plate is provided with a cleaning sponge and cleaning bristles. When the pusher plate moves into the dust collection box, the cleaning sponge and cleaning bristles move synchronously, thereby cleaning the inside of the dust collection box.

[0012] The advantages of this utility model are: the dust collector bags need to be cleaned after a period of use to avoid affecting the normal use of the bag dust collector. Starting the drive motor and fan rotates the threaded rod, which in turn moves the hollow frame up and down on both sides of the dust collector bag via the adjusting block. During this movement, the dust adhering to the surface of the dust collector bag is sucked into the space between the hollow frame and the dust filter through the air duct and suction pipe. When the adjusting block is pressed against the sensor, it is located at the bottom of the dust collector body, and the dust is blocked by the hollow frame, thus preventing the dust from spreading again inside the dust collector body and preventing it from re-adhering to the surface of the dust collector bag, thereby improving the cleaning quality of the dust collector bags.

[0013] This invention sprays water into the dust collection box through a mist spray nozzle, which humidifies the falling dust, increases its weight, and causes it to fall directly to the bottom of the dust collection box, thus preventing the dust from spreading into the air. At the same time, an electric telescopic rod moves the pusher plate, cleaning sponge, and cleaning brush into the dust collection box, pushing the dust to the back of the box door for cleaning, thereby improving the practicality of the dust collector.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a baghouse dust collector includes: a dust collector body 1, a dust collector bag 3 disposed inside the dust collector body 1, a drive motor 2 symmetrically arranged inside the dust collector body 1, a threaded rod 5 fixedly connected to the output end of the drive motor 2, a sensor 4 disposed inside the dust collector body 1, an adjusting block 6 threadedly connected to the threaded rod 5, a hollow frame 7 fixedly connected to one side of the adjusting block 6, and a fan 8 fixedly connected to the upper surface of the hollow frame 7. The fan 8 is a YH-100 model. Sensor 4 is electrically connected to fan 8. Fan 8 is provided with exhaust port 9. The output end of fan 8 is fixedly connected to air duct 10. Air duct 10 is fixedly connected to the inside of hollow frame 7. Dust suction pipe 11 is provided on air duct 10. Dustproof net 12 is fixedly connected to the inner wall of hollow frame 7. Dust discharge port 13 is opened at the bottom of hollow frame 7. Sensor 4 is located below adjustment block 6. Threaded rod 5 is rotatably connected to the inside of dust collector body 1. Two sets of hollow frames 7 are located on both sides of dust collector bag 3.

[0023] After a period of use, the dust collector bag 3 needs to be cleaned to avoid affecting the normal operation of the baghouse dust collector. During actual use, the drive motor 2 and fan 8 are started, causing the threaded rod 5 to rotate. This, in turn, causes the hollow frame 7 to move up and down inside the dust collector body 1 via the adjusting block 6. Since the two sets of hollow frames 7 are located on both sides of the dust collector bag 3, the dust adhering to the surface of the dust collector bag 3 is sucked up through the air duct 10 and suction pipe 11 during movement, causing the dust to be located between the hollow frame 7 and the dustproof net 12. When the adjusting block 6 moves the hollow frame 7 to the bottom of the dust collector bag 3, the adjusting block 6 simultaneously... Pressing sensor 4 causes the fan 8 to stop operating because sensor 4 is electrically connected to fan 8. This eliminates the suction force on the dust, and the dust falls downward through dust outlet 13 and is then discharged outward through dust outlet 19. After the dust is collected, it is located at the bottom of the dust collector body 1 and is blocked by the hollow frame 7, thus preventing the dust from spreading again inside the dust collector body 1 and preventing the dust from adhering to the surface of the dust collector bag 3. Using fan 8 to clean the dust on the dust collector bag 3 reduces contact with the dust collector bag 3 and prevents damage to the dust collector bag 3.

[0024] Please see Figure 1-5 As shown, a dust inlet 14 is fixedly connected to one side of the dust collector body 1, and a clean air outlet 15 is provided on one side of the dust collector body 1. An anti-slip ring 16 is fixedly connected to the dust inlet 14, extending to the outside of the dust inlet 14. A reinforcing ring 17 is fixedly connected to the anti-slip ring 16, and a reinforcing bolt 18 is threaded onto the reinforcing ring 17. A dust outlet 19 is fixedly connected to the bottom of the dust collector body 1, and a dust collection box 20 is provided below the dust outlet 19. A door is hinged to one side of the dust collection box 20. A water pipe 22 is fixedly connected to the outside of the dust collector body 1. A connecting pipe 21 is provided on the water pipe 22. The water pipe 22 is fixedly connected to the inside of the support leg of the dust collector body 1. A mist spray head 23 is provided on the water pipe 22. The mist spray head 23 is fixedly connected to the inside of the dust collection box 20. An electric telescopic rod 24 is fixedly connected to one side of the dust collection box 20. A pusher plate 25 is fixedly connected to the telescopic end of the electric telescopic rod 24. The pusher plate 25 is movably connected to the inside of the dust collection box 20. A cleaning sponge 26 and cleaning bristles 27 are provided at the bottom of the pusher plate 25.

[0025] The pipe carrying dusty gas is inserted into the anti-slip ring 16 and the reinforcing ring 17. Then, the reinforcing bolt 18 is screwed into the reinforcing ring 17, engaging with the circular plate at one end to reduce the ring size. This, combined with the anti-slip ring 16, secures the conveying pipe, preventing leakage when dusty gas enters the dust collector body 1. After being purified by the dust collector bag 3, the dusty gas is discharged through the clean gas outlet 15. After cleaning the dust collector bag 3, the control valve in the dust outlet 19 is opened, allowing dust to pass through. 19 falls into the dust collection box 20. When cleaning the dust collector bag 3, connect the external water source to the connecting pipe 21 so that water enters the water pipe 22. Then spray the water into the dust collection box 20 through the mist spray head 23. This will cause the dust that falls into the dust collection box 20 to fall to the bottom of the dust collection box 20, thereby preventing the dust from flying up again. After the dust is collected, start the electric telescopic rod 24 to drive the pusher plate 25, cleaning sponge 26 and cleaning bristles 27 into the dust collection box 20, thereby pushing the dust to the back of the box door, which makes it easier to clean the dust collection box 20.

[0026] Working principle: The pipe conveying dusty gas is inserted into the anti-slip ring 16 and the reinforcing ring 17. Then, the reinforcing bolt 18 is screwed into the reinforcing ring 17 to fix the conveying pipe. After being purified by the dust collector bag 3, the dusty gas is discharged outward through the clean air outlet 15. The drive motor 2 and fan 8 are started, driving the threaded rod 5 to rotate. This, in turn, causes the hollow frame 7 to move up and down inside the dust collector body 1 via the adjusting block 6. Because the two sets of hollow frames 7 are located on both sides of the dust collector bag 3, the dust adhering to the surface of the dust collector bag 3 is sucked up through the air duct 10 and the suction pipe 11 during movement, so that the dust is located between the hollow frame 7 and the dustproof net 12. When the adjusting block 6 moves the hollow frame 7 to the bottom of the dust collector bag 3, the adjustment... Simultaneously, block 6 presses sensor 4. Since sensor 4 is electrically connected to fan 8, fan 8 stops running, thus eliminating the suction force on dust. Dust then falls downward through dust outlet 13 and is discharged outward through dust outlet 19. When cleaning dust collection bag 3, connect external water source to connecting pipe 21 and spray mist into dust collection box 20 through mist spray head 23. This will cause the dust that falls into dust collection box 20 to fall to the bottom of dust collection box 20, thus preventing dust from flying up again. After dust collection is completed, start electric telescopic rod 24 to drive push plate 25, cleaning sponge 26 and cleaning bristles 27 into dust collection box 20 to clean dust collection box 20.
