Description

Technical Field

[0001] The present application relates to the technical field of dust removal, and in particular to a bag dust collector. Background Art

[0002] Bag dust collector is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter dust-containing gas.

[0003] When using a bag filter, the dust-containing gas is passed into the bag filter through the air inlet pipe. The gas containing finer dust flows into the bag filter along the radial direction of the filter bag and moves from bottom to top along the axial direction of the filter bag to be discharged from the air outlet pipe. At this time, the dust is trapped on the outside of the filter bag, so that the gas is purified. The dust on the outside of the filter bag falls during the backwashing of the bag filter and is discharged along the ash hopper on the lower side of the bag filter.

[0004] In the related art, dust-laden gas always enters the bag filter through a horizontal air inlet pipe. At this time, the filter bag near the air inlet pipe is impacted by the dust-laden gas. Long-term use may easily cause damage to the bag near the air inlet pipe, affecting the dust removal efficiency. Summary of the invention

[0005] In order to reduce the adverse effects on dust removal efficiency, the present application provides a bag dust collector.

[0006] The bag dust collector provided in this application adopts the following technical solution: A bag dust collector comprises a dust collector body and a plurality of filter bags located in the dust collector body, an air inlet pipe is installed on one side of the dust collector body, an air outlet pipe located on the upper side of the air inlet pipe is installed on the other side of the dust collector body, a pump is installed on the air outlet pipe, one end of the air inlet pipe close to the dust collector body is bent downward and fixedly connected to a mounting pipe arranged along one side of the dust collector body, one side of the mounting pipe is provided with a plurality of blowing pipes distributed along the length direction of the mounting pipe, a plurality of nozzles are provided on the upper side of the blowing pipes, and the nozzles correspond to the filter bags one by one.

[0007] By adopting the above technical solution, the dust-containing gas enters the injection pipe through the air inlet pipe and the installation pipe, and enters the bag dust collector along the nozzle on the injection pipe. The pump guides the dust-containing gas in the dust collector body through the air outlet pipe. At this time, the nozzle corresponding to the filter bag makes the dust-containing gas evenly move upward and contact the filter bag, reducing the possibility of damage to the filter bag close to the side of the air inlet pipe and reducing the adverse effect on the dust removal efficiency.

[0008] Optionally, the nozzle is configured as a slope that gradually inclines from the middle to both ends toward a direction approaching the corresponding filter bag.

[0009] By adopting the above technical solution, when the dust-containing gas in the blowing pipe is sprayed to the lower end of the corresponding filter bag through the nozzle, the inclined surfaces on both sides of the nozzle cause part of the dust-containing gas to be sprayed to the surrounding side of the filter bag in a direction perpendicular to the inclined surfaces, thereby increasing the contact area between the dust-containing gas sprayed at the nozzle and the filter bag, reducing the impact of the dust-containing gas sprayed at the nozzle on the lower end of the filter bag, reducing the possibility of damage to the filter bag, and reducing the adverse effects on the dust removal efficiency.

[0010] Optionally, the blowing pipes are all rotatably connected to the mounting pipe, and a first gear is provided at the end of one of the blowing pipes, and a first rack is meshed on one side of the first gear to drive the first gear to drive the nozzle toward one side in the height direction of the dust collector body. Connecting parts that rotate simultaneously are provided between the blowing pipes, and a driving part that drives the first rack to move is provided in the dust collector body.

[0011] By adopting the above technical solution, when spraying dust-containing gas into the filter bag, the nozzle is directed to the corresponding filter bag. When the filter bag needs to be backwashed, the driving member drives the first rack to move downward and drives the first gear to rotate, so that one of the spray pipes drives the remaining spray pipes to rotate with the first gear through the connecting member until the nozzles are all rotated to one side in the height direction of the dust collector body, thereby reducing the possibility of dust on the filter bag entering the nozzle and clogging the nozzle during backwashing, thereby reducing the adverse effect on the dust removal efficiency.

[0012] Optionally, the connecting member includes a first belt sleeved on the outside of two adjacent blowing pipes.

[0013] By adopting the above technical solution, one of the blowing pipes rotates, thereby driving the remaining blowing pipes to rotate simultaneously through the first belt, thereby improving work efficiency.

[0014] Optionally, a torsion spring is provided between the blow pipe and the outer wall of the mounting tube to connect the two. When the torsion spring is at its original length, the nozzle faces the corresponding filter bag. The dust collector body is provided with a limiting member for limiting the blow pipe and making the nozzle face one side of the dust collector body.

[0015] By adopting the above technical solution, when the nozzle sprays dust-containing gas toward the corresponding filter bag, the torsion spring is at its original length. When the nozzle rotates with the spray pipe to one side in the height direction of the dust collector body, the torsion spring is deformed. At this time, one of the spray pipes is limited by the limiter. At this time, the remaining spray pipes are limited by the drive of the connecting piece, thereby reducing the possibility of the torsion spring driving the spray pipe to reset, and reducing the possibility of dust on the filter bag entering the nozzle and clogging the nozzle during backwashing.

[0016] Optionally, one end of one of the blowing pipes away from the mounting pipe is blocked and both sides are provided with limiting grooves perpendicular to the rotation axis of the blowing pipe, and the sides of the limiting grooves away from each other are provided with hydraulic cylinders installed on the outer wall of the dust collector body.

[0017] By adopting the above technical solution, when the torsion spring is at its original length, the line between the limit grooves is perpendicular to the line between the hydraulic cylinders. When the nozzle rotates to face the side of the dust collector body, the hydraulic cylinder is directly opposite to the corresponding limit groove. At this time, the hydraulic cylinder is driven to move in a direction close to each other and inserted into the limit groove, thereby limiting the blowing pipe and reducing the possibility of dust on the filter bag entering the nozzle and clogging the nozzle during backwashing.

[0018] Optionally, a pulse head corresponding to the filter bag is provided on the upper side of the dust collector body, a mounting plate is provided on the lower side of the pulse head, a mounting frame is installed inside the filter bag, the upper end of the mounting frame passes through the mounting plate and is installed with a worm gear, a worm is meshed on one side of the worm gear, and a motor for driving the worm gear to rotate is provided on the dust collector body.

[0019] By adopting the above technical solution, when the filter bag is backwashed by the pulse head, the motor drives the turbine through the worm to drive the corresponding mounting frame and the filter bag to rotate, so that the dust on the outside of the filter bag can be separated from the filter bag and fall under the action of centrifugal force, thereby improving the cleaning efficiency.

[0020] Optionally, the driving member includes a second gear sleeved on one of the worms and fixedly connected to the worm, one side of the second gear is meshed with a second rack fixed to the first rack, and the upper end of the second rack passes through the mounting plate and is slidably connected to the inner wall of the dust collector body.

[0021] By adopting the above technical solution, the motor drives the worm to rotate and drives the second gear installed on the worm to rotate. At this time, the second rack meshing with the second gear pushes the first rack to move downward, so as to drive the nozzle to rotate to the side facing the dust collector body. At this time, the first gear is disengaged from the first gear, and the second gear continues to drive the second rack to move downward until the lower end of the first rack abuts against the inner wall of the dust collector body, and the motor stops, so as to facilitate driving part of the dust to be detached from the filter bag during backwashing of the pulse head, thereby further improving the cleaning efficiency.

[0022] Optionally, the upper side of the mounting plate is provided with vibration grooves corresponding to the worm gear one by one, and the vibration grooves are provided with a first spring with one end fixedly connected to the mounting plate, the upper end of the mounting frame is provided with a connecting block that is inserted into the turbine and slidingly connected to the worm gear along the height direction, the lower side of the connecting block is provided with a mounting ring that is sleeved on the mounting frame, the lower side of the mounting ring is inserted into the vibration groove and abuts against the other end of the first spring, and the dust collector body is provided with a vibration component that drives the mounting ring to vibrate.

[0023] By adopting the above technical solution, when driving the filter bag to rotate and allowing dust to separate from the filter bag, the worm gear drives the mounting frame and the filter bag to rotate through the connecting block, and at the same time, the vibration assembly and the first spring drive the mounting ring to drive the mounting frame to vibrate along the height direction of the mounting frame, which further facilitates driving the dust to separate from the filter bag and improves the cleaning efficiency.

[0024] Optionally, the vibration assembly includes a cam corresponding to the mounting ring one by one and located on the upper side of the mounting ring, the side wall of the cam is always in contact with the corresponding upper side of the mounting ring, a drive shaft is passed through the center of the cam axis, and a second belt is installed between the worm and the drive shaft.

[0025] By adopting the above technical solution, when the worm rotates, the driving shaft is driven by the second belt to drive the cam to rotate, thereby continuously hitting the mounting ring. At this time, the first spring is continuously deformed and drives the mounting ring to reset, so that the driving mounting ring drives the mounting frame to vibrate in the height direction, which is convenient for driving dust out of the filter bag and improving the cleaning efficiency.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The dust-laden gas enters the spray pipe through the air inlet pipe and the installation pipe, and enters the bag dust collector along the nozzle on the spray pipe. The pump guides the dust-laden gas in the dust collector body through the air outlet pipe. At this time, the nozzle corresponding to the filter bag makes the dust-laden gas evenly upward and contact the filter bag, reducing the possibility of damage to the filter bag near the air inlet pipe side and reducing the adverse effect on the dust removal efficiency; 2. When spraying dust-laden gas to the filter bag, the nozzle faces the corresponding filter bag. When the filter bag needs to be backwashed, the driving member drives the first rack to move downward and drives the first gear to rotate, so that one of the spray pipes drives the remaining spray pipes to rotate with the first gear through the connecting member until the nozzles are all rotated to one side in the height direction of the dust collector body, thereby reducing the possibility of dust on the filter bag entering the nozzle and clogging the nozzle during backwashing, thereby reducing the adverse effect on the dust removal efficiency; 3. When driving the filter bag to rotate and allowing dust to separate from the filter bag, the worm gear drives the mounting frame and the filter bag to rotate through the connecting block. At the same time, the vibration assembly and the first spring drive the mounting ring to drive the mounting frame to vibrate along the height direction of the mounting frame, further facilitating the driving of dust to separate from the filter bag and improving the cleaning efficiency.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application embodiment discloses a bag dust collector. Figure 1 and Figure 2 A bag dust collector comprises a vertical dust collector body 1, and a horizontal mounting plate 11 is fixedly connected to the upper side of the interior of the dust collector body 1. Figure 2 , Figure 3 and Figure 4 A plurality of evenly distributed vertical mounting frames 2 are mounted on the mounting plate 11, and filter bags (not shown in the figure) are sleeved and mounted on the outer side walls of the mounting frames 2. In the embodiment of the present application, nine of them are arranged, and a plurality of pulse heads 12 facing the inside of the filter bags and corresponding to the filter bags one by one are arranged on the upper side of the mounting plate 11.

[0036] Reference Figure 2 and Figure 3 A horizontal air outlet pipe 13 is installed on one side of the dust collector body 1, and a pump (not shown in the figure) is installed on the air outlet pipe 13. A horizontal air inlet pipe 3 whose height is lower than the air outlet pipe 13 is installed on the other side of the dust collector body 1. The end of the air inlet pipe 3 close to the dust collector body 1 is inserted into the dust collector body 1 and bent downward to be vertical. The bent end of the air inlet pipe 3 is fixedly connected and connected to a horizontal mounting pipe 31 parallel to the side of the dust collector body 1 close to the air inlet pipe 3 and blocked at both ends. A plurality of horizontal blowing pipes 32 evenly distributed along the length direction of the mounting pipe 31 and perpendicular to the length direction of the mounting pipe 31 are provided on the side of the mounting pipe 31 away from the air inlet pipe 3. The ends of the blowing pipes 32 away from the mounting pipe 31 are all blocked. In the embodiment of the present application, three are provided.

[0037] Three nozzles 33 are arranged on the upper side of the spray pipe 32. Both ends of the nozzles 33 are bent upward and in a direction close to each other, and the nozzles 33 correspond to the filter bags one by one. The ends of the spray pipes 32 close to the mounting pipe 31 are rotatably connected to the mounting pipe 31. A torsion spring (not shown in the figure) connecting the ends of the spray pipes 32 and the mounting pipe 31 is installed between the ends of the spray pipes 32 and the mounting pipe 31. When the torsion spring is at its original length, the nozzles 33 face the corresponding filter bags.

[0038] One end of one of the blowing pipes 32 away from the mounting pipe 31 is sleeved and fixedly connected with a first gear 321, and one side of the first gear 321 is meshed with a first rack 322 that is vertical and moves in the vertical direction. The teeth on the first rack 322 can drive the first gear 321 to drive the blowing pipe 32 to rotate until the nozzle 33 faces the dust collector body 1. The dust collector body 1 is provided with a driving member 34 that drives the first rack 322 to move and a limiting member that limits the blowing pipe 32, and a connecting member that drives the blowing pipe 32 to rotate simultaneously is provided between the blowing pipes 32.

[0039] The dust-containing gas flows through the air inlet pipe 3, the mounting pipe 31 and the blowing pipe 32 and enters the bag dust collector along the nozzle 33. The pump guides the dust-containing gas in the dust collector body 1 through the air outlet pipe 13. At this time, the nozzle 33 faces the corresponding filter bag, the torsion spring is at its original length, and the dust-containing gas is evenly upward and in contact with the filter bag until the dust removal is completed.

[0040] The inclined surfaces on both sides of the nozzle 33 allow part of the dust-containing gas to be sprayed to the surrounding side of the filter bag in a direction perpendicular to the inclined surfaces, thereby increasing the contact area between the dust-containing gas sprayed from the nozzle 33 and the filter bag and reducing the impact of the dust-containing gas sprayed from the nozzle 33 on the lower end of the filter bag.

[0041] When the filter bag needs to be backwashed, the driving member 34 drives the first rack 322 to move downward and drives the first gear 321 to rotate, so that one of the spray pipes 32 drives the remaining spray pipes 32 to rotate with the first gear 321 through the connecting member, until the nozzles 33 are all rotated to one side in the height direction of the dust collector body 1, and the torsion spring is deformed. At this time, one of the spray pipes 32 is limited by the limiting member, and the remaining spray pipes 32 are limited by the connecting member, reducing the possibility of the torsion spring driving the spray pipe 32 to reset and causing dust on the filter bag to enter and block the nozzle 33.

[0042] Reference Figure 2 and Figure 3 The connecting member includes a first belt 36 sleeved on the outer side of one end of two adjacent blowing pipes 32 close to the mounting pipe 31. The blowing pipe 32 corresponding to the first gear 321 is provided with two symmetrically arranged limit grooves 323 at one end away from the mounting pipe 31. When the torsion spring is at the original length, the connecting line between the limit grooves 323 is vertical. The limit member includes a hydraulic cylinder 35 located in the dust collector body 1 and corresponding to the limit grooves 323 one by one. When the nozzle 33 faces one side of the dust collector body 1, the hydraulic cylinder 35 is inserted into the corresponding limit groove 323, and the torsion spring is deformed.

[0043] The driving member 34 drives one of the blowing pipes 32 to rotate and drives the remaining blowing pipes 32 to rotate through the first belt 36. When the torsion spring is at its original length, the line between the limit grooves 323 is perpendicular to the line between the hydraulic cylinders 35. When the nozzle 33 rotates to face the side of the dust collector body 1, the hydraulic cylinder 35 is opposite to the corresponding limit groove 323. At this time, the hydraulic cylinder 35 is driven to move in a direction close to each other and insert into the limit groove 323 to limit the blowing pipe 32, thereby reducing the possibility of dust on the filter bag entering the nozzle 33 and clogging the nozzle 33 during backwashing.

[0044] Reference Figure 3 and Figure 4 The upper ends of the mounting frames 2 pass through the mounting plate 11 and are rotatably connected to the mounting plate 11. The upper ends of the mounting frames 2 are provided with worm wheels 21. The same side of the worm wheels 21 in the same row in the horizontal direction are meshed with the same horizontal worm 22 that is perpendicular to the length direction of the mounting tube 31. A third belt 23 is sleeved between adjacent worm wheels 22, and a motor 24 is installed at the end of one of the worm wheels 22.

[0045] Reference Figure 3 and Figure 5 The driving member 34 includes a second gear 341 which is sleeved on the worm 22 corresponding to the motor 24, and a second rack 342 which is vertically meshed on one side of the second gear 341 and whose lower end is fixed to the first rack 322, and the upper end of the second rack 342 passes through the mounting plate 11 and is slidably connected to the mounting plate 11, and a second spring 343 connecting the upper end of the second rack 342 and the upper side wall inside the dust collector body 1 is installed between the upper end of the second rack 342 and the upper side wall inside the dust collector body 1.

[0046] When the filter bag is backwashed by the pulse head 12, the motor 24 drives the worm gear 21 through the worm 22 to drive the corresponding mounting frame 2 and the filter bag to rotate, so that the dust on the outside of the filter bag can be separated from the filter bag and fall under the action of centrifugal force. At this time, the second gear 341 installed on the worm 22 rotates and drives the second rack 342 to push the first rack 322 to move downward until the nozzle 33 is driven to rotate to the side of the dust collector body 1. At this time, the first rack 322 is disengaged from the first gear 321, and the second gear 341 continues to drive the second rack 342 to move downward until the lower end of the first rack 322 abuts against the inner wall of the dust collector body 1, and the motor 24 stops, so as to facilitate driving part of the dust to be separated from the filter bag when the pulse head 12 is backwashed, thereby improving the cleaning efficiency.

[0047] Reference Figure 4 and Figure 6 A vertical connection block 25 is fixedly connected to one side of the upper end of the mounting frame 2. The mounting frame 2 is slidably connected to the worm gear 21 by inserting the connection block 25 into the corresponding side wall of the worm gear 21. The worm gear 21 is rotationally connected to the upper side of the mounting plate 11. A mounting ring 26 located at the lower side of the connection block 25 is sleeved and fixedly connected to the mounting frame 2. A vibration groove 111 adapted to the mounting ring 26 is opened on the upper side of the mounting plate 11. The lower side of the mounting ring 26 is inserted into the vibration groove 111.

[0048] Two vertical first springs 112 are provided in the vibration groove 111, and the lower ends of the first springs 112 are fixedly connected to the mounting plate 11. The upper ends of the first springs 112 are in contact with the corresponding mounting rings 26. The dust collector body 1 is provided with a vibration component 4 that drives the mounting ring 26 to drive the mounting frame 2 and the filter bag to vibrate.

[0049] Reference Figure 4 and Figure 6 The vibration assembly 4 includes a cam 41 located on the upper side of the mounting ring 26 and corresponding to the mounting ring 26. The side wall of the cam 41 always abuts against the upper side of the corresponding mounting ring 26. The three cams 41 in the same row in the horizontal direction are fixedly connected to the same horizontal driving shaft 42. The same fourth belt 43 is sleeved between two adjacent driving shafts 42, and a second belt 44 connecting the driving shaft 42 close to the motor 24 and the worm 22 corresponding to the motor 24 is installed between the two.

[0050] When driving the filter bag to rotate and allowing dust to leave the filter bag, the worm gear 21 drives the mounting frame 2 and the filter bag to rotate through the connecting block 25. At the same time, the worm 22 rotates and drives one of the drive shafts 42 through the fourth belt 44, and drives the remaining drive shafts 42 to rotate through the fourth belt 43. At this time, the cam 41 continuously rotates and knocks the corresponding mounting ring 26. At this time, the first spring 112 continuously deforms and drives the mounting ring 26 to reset, so that the driving mounting ring 26 drives the mounting frame 2 to vibrate in the height direction, which is convenient for driving dust out of the filter bag and improving the cleaning efficiency.

[0051] The implementation principle of a bag dust collector in an embodiment of the present application is as follows: dust-containing gas enters the bag dust collector, and the pump guides the dust-containing gas in the dust collector body 1 through the outlet pipe 13. At this time, the nozzle 33 faces the corresponding filter bag, and makes the dust-containing gas evenly upward and contact the filter bag. The inclined surfaces on both sides of the nozzle 33 make part of the dust-containing gas sprayed to the surrounding side of the filter bag in a direction perpendicular to the inclined surfaces, reducing the impact of the dust-containing gas sprayed from the nozzle 33 on the lower end of the filter bag until the dust removal is completed.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
