Abstract

This invention discloses a filter bag anti-caking dust collector, relating to the field of dust collector technology. The invention includes a dust collector housing, with an inlet pipe fixedly installed on one side of the bottom for conveying flue gas inwards, and an ash discharge pipe fixedly installed at the bottom end for unloading intercepted ash and slag. A horizontally arranged collecting pipe is fixedly installed on the inner wall of the top of the dust collector housing. This invention, through its individual dust collector mechanism, allows dust-laden flue gas to pass through the filter bags, trapping dust and ash within each bag. A guide fan exhausts air at the top, accelerating flue gas flow while keeping the filter bags upright. When the guide fan stops, the ash discharge fan begins to blow air into the individual dust collector cylinder through the collecting pipe, causing the filter bags to collapse and deform their inner walls, thus reducing the risk of caking of dust and filter slag adhering to the inner walls of the filter bags.

Description

Technical Field

[0001] This invention relates to the field of dust collector technology, and specifically to a filter bag dust collector with anti-caking filter bags. Background Technology

[0002] Baghouse dust collectors can handle flue gas generated during combustion in various boilers and incinerators. The filter bags of baghouse dust collectors are selected according to different dust conditions. They use the filtration effect of fiber fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, the dust is trapped in the filter bags, thus purifying the gas. The dust collector can automatically clean the dust by pumping in compressed air. After the dust leaves the filter bags, it falls into the ash hopper and is collected in a metal ash bucket or other ash unloading device.

[0003] In existing baghouse dust collectors, due to the presence of a certain amount or even a large amount of moisture in industrial flue gas during dust removal operations, dust accumulates on the side walls of the filter bags, causing caking and severely affecting the dust removal and filtration efficiency. Furthermore, the filter bags need to be replaced after a certain period of continuous operation, but initially, the filter bags remain open, making them prone to dust escape and causing pollution. Therefore, a filter bag anti-caking dust collector is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing baghouse dust collectors where the moisture in the flue gas causes dust to clump together, seriously affecting the dust removal and filtration effect, and the dust can easily escape and cause pollution when replacing the filter bags. This invention provides a filter bag anti-clumping dust collector.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A filter bag anti-caking dust collector includes a dust collector cover. An inlet pipe for conveying flue gas is fixedly installed on one side of the bottom of the dust collector cover. An ash discharge pipe for unloading intercepted ash is fixedly installed at the bottom end of the dust collector cover. A horizontally arranged collecting pipe is fixedly installed on the inner wall of the top of the dust collector cover. One end of the collecting pipe extends to the outside of the dust collector cover and is fixedly installed with an exhaust pipe for discharging the flue gas after dust removal. The other end of the collecting pipe extends to the outside of the dust collector cover and is fixedly installed with an ash discharge fan. Multiple vertically arranged dust collector units are arranged inside the dust collector cover. These dust collector units are used to perform bottom-to-top dust removal and ash removal processing on the flue gas discharged from the inlet pipe. The multiple dust collector units are evenly distributed inside the dust collector cover and are all fixedly installed at the bottom of the collecting pipe.

[0007] Furthermore, the dust removal unit mechanism includes a single dust removal cylinder vertically arranged inside the dust collector cover. A connecting pipe is fixedly installed on the single dust removal cylinder. The connecting pipe is fixedly installed at the bottom of the collecting pipe and is connected to the collecting pipe. A receiving plate is fixedly installed at the bottom end of the single dust removal cylinder. A sleeve is fixedly installed on the inner wall of the bottom end of the single dust removal cylinder and is connected to the receiving plate. A dust removal filter bag with its opening facing downward is fitted onto the top end of the sleeve. A guiding fan is fixedly installed on the inner wall of the top of the single dust removal cylinder, and the air outlet of the guiding fan is connected to the connecting pipe.

[0008] Furthermore, multiple annular tracks are fixedly installed on the inner wall of the single dust collector cylinder, and multiple annular drivers are driven and installed on each of the annular tracks. A vertically arranged linear guide rail is fixedly installed on one side of the multiple annular drivers located on the same vertical line, and a linear driver is driven and installed on each of the linear guide rails. A horizontally arranged multi-section telescopic arm is fixedly installed on the side of each linear driver facing the dust collector filter bag. An assembly frame is fixedly installed at the telescopic end of each multi-section telescopic arm. A polygonal rotating plate is rotatably installed on the inner wall of each assembly frame. Multiple evenly distributed hammers are fixedly installed between two polygonal rotating plates. A striking motor is fixedly installed at the bottom of the assembly frame, and the output end of the striking motor is driven and connected to the polygonal rotating plate.

[0009] Furthermore, multiple fastening frames are fixedly installed on the bottom inner wall of the single dust collector, evenly distributed along the sleeve pipe. Each fastening frame is rotatably mounted with a fastening claw. A fastening motor is fixedly installed on one side of each fastening frame. The output end of the fastening motor is drivenly connected to the fastening claw. A fastening plate is fixedly installed on one end of each fastening claw.

[0010] Furthermore, a tapered mesh tube is fixedly installed at the top end of the sleeve.

[0011] Furthermore, a positioning claw is fixedly installed inside the assembly frame, with one end of the positioning claw facing the dust filter bag and extending to the outside of the assembly frame.

[0012] Furthermore, the sleeve has a plurality of evenly distributed storage holes on its periphery, and an inner plate adapted to the fastening plate is rotatably installed inside each storage hole. On the side of the inner plate that is close to the fastening plate, a plurality of matching mating teeth are fixedly installed.

[0013] Furthermore, an annular concave rubber sheet is fixedly installed on the inner wall of the sleeve, and the annular concave rubber sheet covers the inner side of the plurality of inner plates.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention, by setting up a dust collector unit mechanism, allows dust-laden flue gas to pass through the dust collector filter bags, causing dust and ash to be trapped inside each dust collector filter bag. The guide fan exhausts at the top, accelerating the flow of flue gas, while keeping each dust collector filter bag upright. When the guide fan stops, the ash discharge fan starts to blow air into the interior of the unit dust collector cylinder through the collection pipe, causing the dust collector filter bags to collapse, which in turn causes the inner wall of the dust collector filter bags to deform, thereby reducing the risk of dust and filter residue adhering to the inner wall of the dust collector filter bags caking.

[0016] 2. This invention, by setting hammers, ensures that the dust collector filter bag remains vertical under the wind force of the guide fan during the dust removal process. The ring driver and linear driver work together to adjust the position of the multi-section telescopic arm in real time, so that the assembly frame moves to various parts around the dust collector filter bag. Then, the striking motor drives the polygonal rotating plate to start rotating at high speed, so that multiple hammers continuously strike the outer wall of the dust collector filter bag, thereby shaking off the dust adhering to the inner wall of the dust collector filter bag. The dust is then discharged through the conical screen, sleeve pipe, receiving plate and ash discharge pipe, realizing automatic ash discharge and further preventing the dust inside the dust collector filter bag from caking.

[0017] 3. By setting up positioning claws, the present invention enables the dust collector filter bag to be clamped from the inside and outside by the positioning claws and one of the hammers and the sleeve pipe after long-term use. Then, the fastening plate loosens the dust collector filter bag, and multiple sets of assembly frames cooperate to lift the dust collector filter bag from the sleeve pipe and gradually narrow the opening of the dust collector filter bag along the outer wall of the conical mesh cylinder until the bottom of the dust collector filter bag is completely sealed by multiple assembly frames. At this time, the workers can open the individual dust collector cylinder and remove the dust collector filter bag, effectively preventing pollution caused by replacing the dust collector filter bag.

[0018] 4. By setting a fastening plate, the present invention allows the dust collector filter bag to be removed and a new dust collector filter bag to be reattached to the sleeve. Multiple sets of fastening claws, driven by a fastening motor, cause each mating tooth to press against the periphery of the sleeve and clamp and fix the dust collector filter bag from both sides with the inner plate, effectively preventing the dust collector filter bag from falling off the sleeve under the action of wind. The interlocking mating teeth can greatly improve the gripping force of the fastening plate on the dust collector filter bag.

[0019] 5. This invention, by setting an inner plate and an annular concave rubber, allows the annular concave rubber to cover the inner wall of the sleeve pipe for protection and seal the receiving hole. During the dust removal process, some dust will adhere to the sleeve pipe. When the fastening plate and the inner plate clamp the dust filter bag, the inner plate will be pushed inward by the fastening plate, thereby squeezing the annular concave rubber and deforming it. This causes the dust adhering to the inner wall of the annular concave rubber to be shaken off, preventing dust from caking inside the sleeve pipe. Attached Figure Description

Therefore, they should not be construed as limiting the present invention.

[0033] like Figures 1 to 8 As shown, a filter bag anti-caking dust collector includes a dust collector cover 1, such as... Figure 1 As shown, a flue gas inlet pipe 2 for conveying flue gas is fixedly installed on one side of the bottom of the dust collector cover 1. An ash discharge pipe 3 for unloading intercepted ash is fixedly installed at the bottom end of the dust collector cover 1. A horizontally arranged collecting pipe 4 is fixedly installed on the inner wall of the top of the dust collector cover 1. One end of the collecting pipe 4 extends to the outside of the dust collector cover 1 and is fixedly installed with an exhaust pipe 5 for discharging the flue gas after dust removal. The other end of the collecting pipe 4 extends to the outside of the dust collector cover 1 and is fixedly installed with an ash discharge fan 6. Multiple vertically arranged dust removal unit mechanisms are arranged inside the dust collector cover 1. These dust removal unit mechanisms are used to perform bottom-to-top dust removal and ash filtration treatment on the flue gas discharged from the flue gas inlet pipe 2. The multiple dust removal unit mechanisms are evenly distributed inside the dust collector cover 1 and are all fixedly installed at the bottom of the collecting pipe 4. Figure 2 , Figure 3As shown, specifically, the dust removal unit mechanism includes a single dust removal cylinder 7 vertically installed inside the dust collector cover 1. A connecting pipe 8 is fixedly installed on the single dust removal cylinder 7. The connecting pipe 8 is fixedly installed at the bottom of the collecting pipe 4 and is connected to the collecting pipe 4. A receiving plate 9 is fixedly installed at the bottom end of the single dust removal cylinder 7. A sleeve pipe 10 is fixedly installed on the inner wall of the bottom end of the single dust removal cylinder 7 and is connected to the receiving plate 9. Dust removal filter bags 11 with downward openings are fitted to the top of the sleeve pipe 10. A guide fan 29 is fixedly installed on the inner wall of the top of the single dust removal cylinder 7. The air outlet of the guide fan 29 is connected to the connecting pipe 8.

[0034] In this embodiment, the annular track 12 and the annular actuator 13 can be common circumferential actuators in the prior art. The annular actuator 13, as the moving end, can be a self-driven trolley or an arc-shaped slider driven by an external motor and gear set, so that the annular actuator 13 can move in a circle along the annular track 12. The linear guide 14 and the linear actuator 15 can be common linear actuators in the prior art, such as a linear motor module, which drives the moving part as the driving end to move linearly through the electromagnetic force of the motor stator, or uses a screw thread sleeve, belt and pulley, chain and sprocket, etc., to control the driving end to move linearly through the threaded guiding action or meshing action. In addition to electrical energy, components such as cylinders and hydraulic rods can also be used as power sources. The linear guide 14 and the linear actuator 15 in this embodiment can adopt technical solutions including but not limited to the above, depending on the actual situation.

[0035] More specifically, in use, the dust collector with anti-caking filter bag 11 is operated by conveying dust-laden flue gas from the inlet pipe 2 into the interior of the dust collector cover 1. By setting up a dust collection unit mechanism, the dust-laden flue gas enters the dust collection unit mechanism composed of multiple individual dust collection cylinders 7 through each receiving plate 9. The flue gas passes through the dust collection filter bags 11, causing dust and ash to be trapped inside each dust collection filter bag 11. During the dust collection process, the guide fan 29 exhausts at the top to accelerate the flow of flue gas and keep each dust collection filter bag 11 upright. When the guide fan 29 stops, the ash discharge fan 6 starts to blow air into the interior of the individual dust collection cylinder 7 through the collecting pipe 4. The dust collection filter bags 11 collapse, which in turn causes the inner wall of the dust collection filter bags 11 to deform, thereby reducing the risk of caking of dust and filter residue adhering to the inner wall of the dust collection filter bags 11.

[0036] like Figure 3 , Figure 7As shown, specifically, multiple annular tracks 12 are fixedly installed on the inner wall of the single dust collector 7. Multiple annular drivers 13 are driven and installed on each annular track 12. A vertically arranged linear guide rail 14 is fixedly installed on one side of the multiple annular drivers 13 located on the same vertical line. A linear driver 15 is driven and installed on each linear guide rail 14. A horizontally arranged multi-section telescopic arm 16 is fixedly installed on the side of the linear driver 15 facing the dust collector filter bag 11. An assembly frame 17 is fixedly installed at the telescopic end of each multi-section telescopic arm 16. A polygonal rotating plate 18 is rotatably installed on the inner wall of the assembly frame 17. Multiple evenly distributed hammers 19 are fixedly installed between two polygonal rotating plates 18. A striking motor 20 is fixedly installed at the bottom of the assembly frame 17. The output end of the striking motor 20 is driven and connected to the polygonal rotating plate 18.

[0037] More specifically, by setting hammers 19, the dust filter bag 11 is kept vertical under the wind force of the guide fan 29 during the dust removal process. The ring drive 13 and the linear drive 15 cooperate to adjust the position of the multi-section telescopic arm 16 in real time, so that the assembly frame 17 moves to various parts around the dust filter bag 11. Then, the striking motor 20 drives the polygonal rotating plate 18 to start rotating at high speed, so that multiple hammers 19 continuously strike the outer wall of the dust filter bag 11, thereby shaking off the dust attached to the inner wall of the dust filter bag 11. The dust is then discharged through the conical screen cylinder 30, the sleeve pipe 10, the receiving plate 9 and the ash discharge pipe 3, realizing automatic ash discharge and further preventing the dust inside the dust filter bag 11 from caking.

[0038] like Figure 4 , Figure 5 , Figure 7 As shown, specifically, a positioning claw 21 is fixedly installed inside the assembly frame 17, one end of the positioning claw 21 faces the dust removal filter bag 11 and extends to the outside of the assembly frame 17, and a conical mesh cylinder 30 is fixedly installed at the top of the sleeve pipe 10.

[0039] In this embodiment, the conical mesh cylinder 30 has its large opening facing downwards and is connected to the sleeve pipe 10, while its small opening faces upwards and extends into the interior of the dust collector filter bag 11.

[0040] More specifically, by setting positioning claws 21, after long-term use of the dust filter bag 11, each assembly frame 17 approaches the side wall of the dust filter bag 11 while the dust filter bag 11 is kept upright. The positioning claws 21 and one of the hammers 19 clamp the dust filter bag 11 from the inside and outside with the sleeve 10. Then the fastening plate 25 loosens the dust filter bag 11. Multiple sets of assembly frames 17 cooperate with each other to lift the dust filter bag 11 from the sleeve 10 and gradually narrow the opening of the dust filter bag 11 along the outer wall of the conical mesh cylinder 30 until the bottom of the dust filter bag 11 is completely sealed by multiple assembly frames 17. At this time, the staff can open the individual dust collector cylinder 7 and remove the dust filter bag 11, effectively preventing pollution caused by replacing the dust filter bag 11.

[0041] like Figure 3 , Figure 6 , Figure 8 As shown, specifically, multiple fastening brackets 22 evenly distributed along the sleeve pipe 10 are fixedly installed on the bottom inner wall of the single dust collector 7. Each fastening bracket 22 is rotatably mounted with a fastening claw 23. A fastening motor 24 is fixedly installed on one side of each fastening bracket 22. The output end of the fastening motor 24 is drivenly connected to the fastening claw 23. A fastening plate 25 is fixedly installed on one end of each fastening claw 23. Multiple evenly distributed storage holes 1001 are opened on the periphery of the sleeve pipe 10. An inner plate 26 adapted to the fastening plate 25 is rotatably installed inside each storage hole 1001. Multiple matching mating teeth 27 are fixedly installed on the side of the inner plate 26 that is close to the fastening plate 25.

[0042] More specifically, by setting the fastening plate 25, the dust filter bag 11 can be removed and a new dust filter bag 11 can be reattached to the sleeve pipe 10. Multiple sets of fastening claws 23, driven by the fastening motor 24, drive each mating tooth 27 to press against the periphery of the sleeve pipe 10, and clamp and fix the dust filter bag 11 from both sides with the inner plate 26, effectively preventing the dust filter bag 11 from falling off the sleeve pipe 10 under the action of wind. The interlocking mating teeth 27 can greatly improve the gripping force of the fastening plate 25 on the dust filter bag 11.

[0043] like Figure 5 As shown, specifically, an annular concave rubber 28 is fixedly installed on the inner wall of the sleeve 10, and the annular concave rubber 28 covers the inner side of multiple inner plates 26.

[0044] More specifically, by setting the inner plate 26 and the annular concave rubber 28, the annular concave rubber 28 covers the inner wall of the sleeve 10 to provide protection. The top and bottom sides of the annular concave rubber 28 are fixedly connected to the inner wall of the sleeve 10, while the middle area does not contact the sleeve 10, thereby sealing the receiving hole 1001. During the dust removal process, some dust will adhere to the sleeve 10. When the fastening plate 25 and the inner plate 26 clamp the dust filter bag 11, the inner plate 26 will be pushed inward by the fastening plate 25, thereby squeezing the annular concave rubber 28 and deforming it. This causes the dust adhering to the inner wall of the annular concave rubber 28 to be shaken off, preventing dust from caking inside the sleeve 10.

[0045] In summary: When this dust collector with anti-caking filter bags 11 is in use, dust-laden flue gas is transported from the inlet pipe 2 into the interior of the dust collector casing 1. Through the setup of individual dust collection units, the dust-laden flue gas enters the individual dust collection unit composed of multiple individual dust collection cylinders 7 via various receiving plates 9. The flue gas passes through the dust collection filter bags 11, causing dust and ash to be trapped inside each filter bag 11. During the dust collection process, the guide fan 29 exhausts air at the top, accelerating the flow of flue gas and keeping each filter bag 11 upright. When the guide fan 29 stops, the ash discharge fan 6 begins to blow air into the individual dust collection cylinder 7 through the collecting pipe 4, causing the filter bags 11 to collapse, resulting in deformation of the inner wall of the filter bags 11, thereby reducing the adhesion of dust and ash. To mitigate the risk of dust and filter residue caking on the inner wall of the dust collector filter bag 11, hammers 19 are installed. During dust removal, the dust collector filter bag 11 remains vertical under the force of the guide fan 29. The ring drive 13 and linear drive 15 work together to adjust the position of the multi-section telescopic arm 16 in real time, moving the assembly frame 17 to various locations around the dust collector filter bag 11. Then, the striking motor 20 drives the polygonal rotating plate 18 to rotate at high speed, causing multiple hammers 19 to continuously strike the outer wall of the dust collector filter bag 11, thereby shaking off the dust adhering to the inner wall of the dust collector filter bag 11. The dust is then discharged through the conical screen cylinder 30, sleeve pipe 10, receiving plate 9, and ash discharge pipe 3, achieving automatic ash discharge. This further prevents dust caking inside the dust collector filter bag 11 by installing positioning claws 21. This allows the assembly racks 17 to approach the side wall of the dust collector filter bag 11 while it remains upright after long-term use. The positioning claws 21 and one of the hammers 19, along with the sleeve 10, clamp the dust collector filter bag 11 from the inside and outside. Then, the fastening plate 25 loosens the dust collector filter bag 11. Multiple assembly racks 17 work together to lift the dust collector filter bag 11 upwards from the sleeve 10, gradually narrowing the opening of the dust collector filter bag 11 along the outer wall of the conical mesh cylinder 30 until the bottom of the dust collector filter bag 11 is completely sealed by the multiple assembly racks 17. At this point, the operator can open the individual dust collector cylinder 7 and remove the dust collector filter bag 11, effectively preventing pollution caused by replacing the dust collector filter bag 11. The fastening plate 25 facilitates the removal of the dust collector filter bag 11 and the installation of a new dust collector filter. The filter bag 11 is reattached to the sleeve 10. Driven by the fastening motor 24, multiple sets of fastening claws 23 cause the mating teeth 27 to press against the periphery of the sleeve 10, and clamp and fix the dust filter bag 11 from both sides with the inner plate 26, effectively preventing the dust filter bag 11 from falling off the sleeve 10 under the action of wind. The interlocking mating teeth 27 can greatly improve the gripping force of the fastening plate 25 on the dust filter bag 11. By setting the inner plate 26 and the annular concave rubber 28, the annular concave rubber 28 covers the inner wall of the sleeve 10 to play a protective role. The top and bottom sides of the annular concave rubber 28 are fixedly connected to the inner wall of the sleeve 10, while the middle area does not contact the sleeve 10, thereby sealing the receiving hole 1001.During the dust removal process, some dust adheres to the sleeve connector 10. When the fastening plate 25 and the inner plate 26 clamp the dust filter bag 11, the inner plate 26 will flip inward under the push of the fastening plate 25, thereby squeezing the annular concave rubber 28, causing the annular concave rubber 28 to deform. This shakes off the dust adhering to the inner wall of the annular concave rubber 28, preventing dust from caking inside the sleeve connector 10.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
