Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a vibrating bag filter dust collector. Background Technology

[0002] Baghouse dust collectors are a commonly used type of dust collector, with advantages such as good dust removal effect and high dust removal efficiency. They are used in large industrial sites and chemical plants. The vibrating baghouse dust collector is one of them, which is convenient for dust removal. It is necessary to use the vibrating baghouse dust collector to remove dust in environments with high dust concentration.

[0003] Chinese Patent Publication No. CN 221732686 U discloses a vibratory bag filter dust collector, relating to the field of dust collector technology. This utility model includes a housing with a dust outlet pipe fixedly connected to the bottom. An adjustment device is provided on the outer surface of the housing, comprising four rectangular rods, one end of which is fixedly connected to the outer surface of the housing. A rectangular cylinder is slidably connected to the outer surface of each rectangular rod. This utility model uses two semi-rings. Under the action of a first threaded rod and a second threaded rod, the first and second threaded rods respectively drive a semi-ring connected to an extension block to move towards each other on both sides of the rubber tube until the two semi-rings completely clamp the outer surface of the rubber tube. This reinforces the connection between the rubber tube and the dust collection pipe, preventing gaps at the connection and ensuring the normal operation of the dust collector.

[0004] Existing vibratory baghouse dust collectors cannot apply impact force evenly to the filter bags during the cleaning process, which easily leads to wear and tear on the filter bags, resulting in poor cleaning uniformity and affecting the service life of the filter bags. Therefore, a vibratory baghouse dust collector is proposed to address the above problems. Utility Model Content

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

[0006] The technical solution adopted by this utility model to solve its technical problem is a vibrating bag filter, including a housing. A controller is installed on the outer wall of the housing, and a fixing plate is installed on the inner wall of the housing. A perforated plate is rotatably installed on the fixing plate, and multiple sets of filter bags are installed on the perforated plate. A fixing ring is installed on the top side of the perforated plate, and a large spur gear is fixedly installed on the periphery of the fixing ring. A first rotating shaft is rotatably installed on the fixing plate, and a small spur gear and a first bevel gear are fixedly sleeved on the first rotating shaft. The small spur gear and the large spur gear mesh with each other. A second rotating shaft is rotatably installed on the side wall of the housing, and a second bevel gear is fixedly sleeved on the second rotating shaft. The second bevel gear meshes with the first bevel gear. A motor is installed on the outer wall of the housing via a base, and the output shaft of the motor is fixed to the second rotating shaft. The motor is connected to the controller via an internal circuit. A mounting bracket is fixedly installed on the inner wall of the top plate of the housing. A soot blowing pipe is installed on the bottom side of the mounting bracket, and multiple nozzles are installed on the bottom side of the soot blowing pipe. An air storage tank is fixedly installed on the outer wall of the housing, and an air guide pipe is installed on the air storage tank. The other end of the air guide pipe is connected to the soot blowing pipe, and an electromagnetic pulse valve is installed on the air guide pipe. The electromagnetic pulse valve is connected to the controller via an internal circuit. High-pressure gas is applied to the filter bags, causing the filter bags to deform and vibrate, thus cleaning the filter bags. During the cleaning process, the perforated plate drives multiple sets of filter bags to rotate slowly, so that the high-pressure gas is applied evenly to the filter bags, avoiding the high-pressure gas being applied in one place, which can easily cause wear on the filter bags over time. This improves the uniformity of filter bag cleaning and extends the service life of the filter bags.

[0007] Preferably, an air inlet pipe is installed on the side wall of the housing, a baffle is installed on the inner wall of the housing at the air inlet, an air outlet pipe is installed on the other side wall of the housing, a dust hopper is installed on the bottom side of the housing, and a stand is installed on the housing. By installing a baffle at the air inlet, dust-laden gas enters the housing through the air inlet pipe. Large dust particles are blocked by the baffle and separated by gravity and inertia, falling directly into the dust hopper. The remaining dust-laden gas enters the filter bag filtration area for filtration, achieving pre-filtration of the gas and improving the filtration effect.

[0008] The advantages of this utility model are:

[0009] 1. This utility model achieves dust removal by applying high-pressure gas to the filter bag, causing the filter bag to deform and vibrate. During the dust removal process, the perforated plate drives multiple sets of filter bags to rotate slowly, so that the high-pressure gas is applied evenly to the filter bags. This avoids the high-pressure gas being applied in one place, which can easily cause the filter bags to wear out over time. This improves the uniformity of dust removal and extends the service life of the filter bags.

[0010] 2. By installing a baffle at the air inlet, the dust-laden gas enters the housing through the air inlet pipe. Large dust particles are blocked by the baffle and separated by gravity and inertia, falling directly into the ash hopper. The remaining dust-laden gas enters the filter bag filtration area for filtration, thus achieving pre-filtration of the gas and improving the filtration effect. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4As shown, a vibrating bag filter includes a housing 1. A controller 2 is installed on the outer wall of the housing 1. A fixing plate 3 is installed on the inner wall of the housing 1. A perforated plate 4 is rotatably installed on the fixing plate 3. Multiple sets of filter bags 5 are installed on the perforated plate 4. A fixing ring 6 is installed on the top side of the perforated plate 4. A large spur gear 7 is fixedly installed on the periphery of the fixing ring 6. A first rotating shaft 8 is rotatably installed on the fixing plate 3. A small spur gear 9 and a first bevel gear 10 are fixedly sleeved on the first rotating shaft 8. The small spur gear 9 and the large spur gear 7 mesh with each other. A second rotating shaft 11 is rotatably installed on the side wall of the housing 1. A second bevel gear 12 is fixedly sleeved on the second rotating shaft 11. The second bevel gear 12 meshes with the first bevel gear 10. A motor 13 is installed on the outer wall of the housing 1 via a base. The output shaft of the motor 13 is fixedly connected to the second rotating shaft 11. The motor 13 is connected to the controller 2 through an internal circuit. A fixing frame 14 is fixedly installed on the inner wall of the top plate of the housing 1. A soot blowing pipe 15 is installed on the bottom side of the frame 14, and multiple sets of nozzles 16 are installed on the bottom side of the soot blowing pipe 15. An air storage tank 17 is fixedly installed on the outer wall of the housing 1, and an air guide pipe 18 is installed on the air storage tank 17. The other end of the air guide pipe 18 is connected to the soot blowing pipe 15, and an electromagnetic pulse valve 19 is installed on the air guide pipe 18. The electromagnetic pulse valve 19 is connected to the controller 2 through an internal circuit. During operation, the existing vibrating bag dust collector cannot evenly apply pressure to the filter bag 5 during the dust removal process. The impact force can easily cause wear on the filter bag 5, resulting in poor uniformity of dust removal and affecting the service life of the filter bag 5. The dust-laden gas enters the housing 1 through the inlet pipe 20. Large dust particles are separated by gravity and inertia and fall directly into the ash hopper 23. The remaining dust-laden gas enters the filtration area of ​​the filter bag 5. The dust is trapped on the outer surface of the filter bag 5 when the gas passes through it. The purified gas enters the housing 1 through the opening of the filter bag 5 and is finally discharged through the outlet pipe 22.

[0020] As the filtration time increases, the dust layer on the filter bag 5 continues to thicken, requiring regular cleaning of the filter bag 5. The controller 2 controls the opening of the electromagnetic pulse valve 19, and the high-pressure gas in the air tank 17 quickly enters the soot blowing pipe 15 from the air guide pipe 18, and finally sprays out from the nozzle 16. The high-pressure gas is applied to the filter bag 5, causing the filter bag 5 to deform and vibrate, thus vibrating the filter bag 5. This causes the dust adhering to the outer surface of the filter bag 5 to be peeled off and fall into the ash hopper 23, thus cleaning the filter bag 5.

[0021] During the cleaning process of filter bags 5, the motor 13 operates, driving the second rotating shaft 11 to rotate. The second rotating shaft 11 drives the second bevel gear 12 to rotate, which in turn drives the first bevel gear 10 to rotate. The first bevel gear 10 drives the first rotating shaft 8 to rotate, which in turn drives the small spur gear 9 to rotate. The small spur gear 9 drives the large spur gear 7 to rotate slowly, which in turn drives the fixing ring 6 to rotate slowly. The fixing ring 6 drives the perforated plate 4 to rotate slowly, which in turn drives multiple sets of filter bags 5 to rotate slowly. This ensures that the high-pressure gas is applied evenly to the filter bags 5, preventing the high-pressure gas from being applied in one place, which would cause the filter bags 5 to wear easily over time. This improves the uniformity of cleaning the filter bags 5 and extends their service life.

[0022] Please see Figure 5 As shown, an air inlet pipe 20 is installed on the side wall of the housing 1, a baffle 21 is installed on the inner wall of the housing 1 at the air inlet, an air outlet pipe 22 is installed on the other side wall of the housing 1, a dust hopper 23 is installed on the bottom side of the housing 1, and a stand 24 is installed on the housing 1. During operation, the existing vibrating bag filter cannot pre-filter large particulate impurities in the gas during the filtration process, resulting in poor filtration effect. By installing a baffle 21 at the air inlet, the dust-laden gas enters the housing 1 from the air inlet pipe 20. Large dust particles are blocked by the baffle 21 and separated by gravity and inertia, falling directly into the dust hopper 23. The remaining dust-laden gas enters the filter bag 5 filtration area for filtration, realizing the pre-filtration of the gas and improving the filtration effect.

[0023] Working principle: Existing vibratory baghouse dust collectors cannot evenly apply impact force to the filter bags 5 during the dust removal process, leading to wear and tear on the filter bags 5, resulting in poor uniformity of dust removal and affecting the service life of the filter bags 5. Dust-laden gas enters the housing 1 through the inlet pipe 20. Large dust particles are separated by gravity and inertia and fall directly into the ash hopper 23. The remaining dust-laden gas enters the filtration zone of the filter bags 5. Dust is trapped on the outer surface of the filter bags 5 as the gas passes through them. The purified gas then enters the upper part of the housing 1 through the opening of the filter bags 5 and finally exits through the outlet pipe 2. 2. Discharge; As the filtration time increases, the dust layer on the filter bag 5 continues to thicken, requiring regular cleaning of the filter bag 5. The controller 2 opens the electromagnetic pulse valve 19, and the high-pressure gas in the air tank 17 quickly enters the soot blowing pipe 15 through the air guide pipe 18, finally being ejected from the nozzle 16. The high-pressure gas is applied to the filter bag 5, causing it to deform and vibrate, thus vibrating the filter bag 5 and causing the dust adhering to the outer surface of the filter bag 5 to be peeled off and fall into the dust hopper 23, achieving the cleaning of the filter bag 5. During the cleaning process of the filter bag 5, the motor 13 operates, driving the second... Rotating shaft 11 rotates, driving the second bevel gear 12 to rotate. The second bevel gear 12 pushes the first bevel gear 10 to rotate. The first bevel gear 10 drives the first rotating shaft 8 to rotate. The first rotating shaft 8 drives the small spur gear 9 to rotate. The small spur gear 9 pushes the large spur gear 7 to rotate slowly. The large spur gear 7 drives the fixing ring 6 to rotate slowly. The fixing ring 6 drives the perforated plate 4 to rotate slowly. The perforated plate 4 drives multiple sets of filter bags 5 to rotate slowly, ensuring that the high-pressure gas is evenly applied to the filter bags 5, preventing the high-pressure gas from being applied to one place for a long time. The wear-resistant material is beneficial for improving the uniformity of dust removal of filter bags 5 and extending their service life. Existing vibratory baghouse dust collectors cannot pre-filter large particulate impurities in the gas during the filtration process, resulting in poor filtration effect. By installing baffle 21 at the air inlet, the dust-laden gas enters the housing 1 from the air inlet pipe 20. Large dust particles are blocked by baffle 21 and separated by gravity and inertia, falling directly into the ash hopper 23. The remaining dust-laden gas enters the filtration area of ​​filter bags 5 for filtration, thus achieving pre-filtration of the gas and improving the filtration effect.
