Description

Technical Field

[0001] This application relates to the field of soot blowers, and in particular to a threaded air soot blower. Background Art

[0002] True air soot blowers are commonly used in coal-fired and oil-fired boilers such as industrial boilers, utility boilers, biomass boilers, waste incinerators, process furnaces, and heating furnaces. Existing boiler equipment is equipped with soot blowers such as furnace soot blowers, long retractable soot blowers, semi-retractable soot blowers, and fixed rotary soot blowers. Among them, the long retractable soot blower is mainly used to clean the screen type and tube bundle heating surfaces of the boiler.

[0003] The long retractable soot blower mainly relies on the linkage of racks and gears to make the soot blowing pipe retract and extend, and makes the soot blowing pipe rotate during the movement through a chain and a transmission structure.

[0004] Regarding the above related technologies, the inventor believes that during the rotation and movement of the soot blowing pipe, the soot blowing pipe rubs against the boiler, and at the same time, the surface of the soot blowing pipe extending into the boiler is extremely easy to adhere to slag. Excessive accumulation of slag will affect the normal movement of the soot blowing pipe. Summary of the Invention

[0005] In order to improve the situation of excessive slag on the surface of the soot blowing pipe, ensure the long-term stable movement of the soot blowing pipe, and ensure the soot blowing efficiency of the soot blowing pipe, this application provides a threaded air soot blower.

[0006] A threaded air soot blower provided by this application adopts the following technical solutions:

[0007] A threaded air soot blower includes a first base plate and a second base plate. A plurality of connecting frames are commonly connected between the first base plate and the second base plate. A soot blowing threaded rod is arranged between the first base plate and the second base plate. The two ends of the soot blowing threaded rod are respectively rotatably connected to the first base plate and the second base plate. The first base plate is provided with a driving device for driving the rotation of the soot blowing threaded rod. A soot blowing outer pipe is arranged at a position below the soot blowing threaded rod. A soot blowing inner pipe is connected inside the soot blowing outer pipe. One end of the soot blowing inner pipe is connected to the first base plate. A telescopic opening is formed in the second base plate corresponding to the position of the soot blowing outer pipe. One end of the soot blowing outer pipe extending out of the telescopic opening is closed. A plurality of soot blowing holes are formed in the side wall of the soot blowing outer pipe near the closed end. The soot blowing threaded rod is connected with a moving device for driving the rotation and movement of the soot blowing outer pipe. A plurality of rubbing devices for rubbing the outer wall of the soot blowing outer pipe are arranged on two connecting frames at the lower position. The movement process of the moving device can drive the rubbing device to rub the soot blowing outer pipe.

[0008] By adopting the above technical solution, when the user uses it, during the process of the driving device driving the soot blowing threaded rod to rotate, the rotation of the soot blowing threaded rod can drive the moving device to move along the soot blowing threaded rod. The moving device drives the soot blowing outer tube to move towards the telescopic port, and makes the soot blowing outer tube extend out of the telescopic port. Air is introduced into the soot blowing inner tube, and the air can enter the soot blowing outer tube through the soot blowing inner tube and spray from the soot blowing holes towards the inner furnace wall, ensuring that the soot blowing outer tube can perform normal telescopic movement. When the moving device moves, it drives the soot blowing outer tube to rotate, ensuring that the soot blowing outer tube can perform telescopic movement while rotating, improving the cleaning area and cleaning efficiency of the soot blowing outer tube. Driving the soot blowing outer tube to move by the rotation of the soot blowing threaded rod can ensure that the soot blowing outer tube can move more stably, and at the same time can reduce the wear degree of the soot blowing threaded rod and the soot blowing outer tube, avoiding the user from frequently replacing the soot blowing threaded rod.

[0009] Optionally, the driving device includes a double-shaft motor disposed above the first base plate. A first driving gear is fixedly connected to the output shaft of the double-shaft motor close to the first base plate. A second driving gear is rotatably connected to the first base plate. A driving chain is jointly engaged with the first driving gear and the second driving gear. One end of the soot blowing threaded rod passes through the first base plate and is fixedly connected to the second driving gear.

[0010] By adopting the above technical solution, when the user uses it, the double-shaft motor is started. The output shaft of the double-shaft motor close to the first base plate drives the first driving gear to start rotating. The first driving gear drives the second driving gear to start rotating through the driving chain. The soot blowing threaded rod rotates together with the second driving gear, ensuring that the soot blowing threaded rod can rotate normally.

[0011] Optionally, a driving turntable is fixedly connected to the output shaft of the double-shaft motor far from the first base plate.

[0012] By adopting the above technical solution, when the user uses it, the user rotates the driving turntable, and the driving turntable can also drive the double-shaft motor to operate normally, ensuring that when a power failure occurs, the user can manually drive the soot blowing threaded rod to rotate, ensuring the working efficiency, and ensuring that when a power failure occurs, the user can take out the soot blowing outer tube by rotating the driving turntable.

[0013] Optionally, the moving device includes a moving frame. Both the soot blowing threaded rod and the soot blowing outer tube pass through the moving frame. The soot blowing outer tube is rotatably connected to the moving frame. A positioning disk is rotatably connected to the side plate of the moving frame close to the second base plate at a position corresponding to the soot blowing threaded rod. The soot blowing threaded rod passes through the positioning disk. A plurality of moving grooves are formed in the soot blowing threaded rod, and the moving grooves are arranged along the length direction of the soot blowing threaded rod. A positioning block is arranged at each position of the positioning disk corresponding to the moving grooves of the soot blowing threaded rod, and the positioning block slides in the moving grooves of the soot blowing threaded rod. A copper sleeve is threadedly connected to the soot blowing threaded rod, and the copper sleeve is fixedly connected to the moving frame.

[0014] By adopting the above technical solution, when the user uses it, the process of the soot blowing screw rod rotating drives the copper sleeve to move along the soot blowing screw rod. The copper sleeve drives the moving frame to move. During the movement of the moving frame, the positioning disc is driven to rotate around the soot blowing screw rod, and the positioning disc slides along the soot blowing screw rod. The positioning block in the positioning disc slides in the moving groove of the soot blowing screw rod. The moving frame drives the outer soot blowing pipe to move towards the telescopic port and makes the outer soot blowing pipe extend out of the telescopic port, ensuring that the outer soot blowing pipe can perform stable telescopic movement and improving the stability of soot blowing.

[0015] Optionally, the moving device further includes a driving gear threadedly connected to the soot blowing screw rod. The driving gear is located inside the moving frame. The driving gear is connected with a plurality of limiting blocks. The limiting blocks are slidably arranged in the moving groove of the soot blowing screw rod. The driving gear is rotatably connected to the copper sleeve. The outer soot blowing pipe is fixedly connected with a driven gear. The driven gear is located inside the moving frame. The driving gear and the driven gear are meshed with each other.

[0016] By adopting the above technical solution, when the user uses it, when the soot blowing screw rod rotates, the driving gear can rotate together with the soot blowing screw rod. When the copper sleeve moves along the soot blowing screw rod, it drives the driving gear to rotate around the soot blowing screw rod. At the same time, the driving gear moves along the moving groove of the soot blowing screw rod through its own limiting blocks. The process of the driving gear rotating drives the driven gear to rotate together. The outer soot blowing pipe rotates together with the driven gear, ensuring that the outer soot blowing pipe can rotate normally during the telescopic process, ensuring the cleaning area and cleaning efficiency of the outer soot blowing pipe. By driving the outer soot blowing pipe to move in the way of the rotation of the soot blowing screw rod, the situation of unstable movement of the outer soot blowing pipe is avoided. At the same time, the wear degree between the soot blowing screw rod and the copper sleeve is reduced, and the user does not need to replace the soot blowing screw rod frequently.

[0017] Optionally, support frames are arranged at positions near the bottom on both sides of the moving frame. A support gear is rotatably connected to each position of the support frame away from the base plate 1. The connecting frame includes a connecting horizontal plate and a connecting vertical plate. The connecting horizontal plate is horizontally arranged, and the connecting vertical plate is vertically arranged. The connecting horizontal plate and the connecting vertical plate together form an angle steel. The angle steel is arranged along the length direction of the soot blowing screw rod. The two ends of the angle steel are fixedly connected to the base plate 1 and the base plate 2 respectively. A plurality of walking grooves are opened on both connecting horizontal plates at the lower positions. The walking grooves are arranged in an array along the length direction of the connecting horizontal plate. The tooth blocks of the support gears can extend into the walking grooves.

[0018] By adopting the above technical solution, when the user uses it, when the moving frame moves, it drives the support frame to move along the length direction of the connecting frame. The support frame drives the support gears to roll along the walking grooves on the connecting horizontal plate. The support gears support the support frame and the moving frame, ensuring that the moving process of the moving frame is more stable. At the same time, the friction between the moving frame and the connecting horizontal plate is reduced, and the service life of the moving frame and the connecting horizontal plate is prolonged.

[0019] Optionally, a limiting wheel is rotatably connected to the top of each of the support frames. The axial line of the limiting wheel is perpendicular to the soot blowing threaded rod, and the two limiting wheels respectively abut against the two connecting vertical plates located below.

[0020] By adopting the above technical solution, when the user uses it, when the moving frame moves, it drives the support frame to move along the length direction of the connecting frame. The support frame drives the limiting wheel to roll on the connecting vertical plate. The limiting wheel supports the support frame and the moving frame, ensuring that the moving process of the moving frame is more stable, while reducing the friction between the moving frame and the connecting vertical plate, and extending the service life of the moving frame and the connecting vertical plate.

[0021] Optionally, the brushing device includes a plurality of rotating rods hinged to two connecting cross plates located at the lower positions. The rotating rods are arranged in an array along the length direction of the connecting cross plate. The rotating rods correspond to the walking grooves one by one. Rotating grooves are provided at the positions of each walking groove on the side where the two connecting cross plates are close to each other. The rotating grooves communicate with the walking grooves. The rotating rods are hinged in the rotating grooves of the connecting cross plates. One end of the rotating rod extends into the walking groove. The supporting gear can abut against the rotating rod. A brushing plate is fixedly connected to one end of each rotating rod away from the position where it is hinged to the connecting cross plate. The brushing plate can abut against the soot blowing outer tube.

[0022] By adopting the above technical solution, when the user uses it, when the supporting gear moves along with the support frame, during the rotation process of the supporting gear, the rack of the supporting gear can sequentially enter the walking grooves of the connecting cross plates. The rack of the supporting gear abuts against and presses the rotating rod, and the rotating rod rotates. One end of the rotating rod close to the brushing plate tilts up. The brushing plate tilts up along with the rotating rod and abuts against the soot blowing outer tube. The brushing plate can brush the outer surface of the soot blowing outer tube. Along with the moving process of the supporting gear, a plurality of rotating rods and brushing plates can be sequentially pressed up by the supporting gear. The brushing plate can brush the outer surface of the soot blowing outer tube, ensuring that during the movement of the soot blowing outer tube, the furnace ash and impurities adhering to the soot blowing outer tube can be timely cleaned by the brushing plate, ensuring the cleanliness of the surface of the soot blowing outer tube, extending the service life of the soot blowing outer tube, and at the same time ensuring that the soot blowing outer tube can move normally.

[0023] Optionally, two supporting blocks are arranged on one side of the second base plate close to the first base plate. The two supporting blocks are both located below the soot blowing outer tube. The two supporting blocks are both inclined downward from the end far away from the soot blowing outer tube to the end close to the soot blowing outer tube. Each supporting block is rotatably connected with a rotating bead abutting against the soot blowing outer tube.

[0024] By adopting the above technical solution, when the user uses it, when the soot blowing outer tube moves, it can drive the rotating bead to rotate, reducing the friction between the soot blowing outer tube and the rotating bead, ensuring that the soot blowing outer tube moves more smoothly, and reducing the wear between the second base plate and the soot blowing outer tube.

[0025] Optionally, two sliding inclined surfaces are provided on both sides of each positioning block. The two sliding inclined surfaces on the side away from the limiting block are arranged in a direction away from each other from the end away from the limiting block to the end close to the limiting block, and the two sliding inclined surfaces on the side close to the limiting block are arranged in a direction away from each other from the end close to the limiting block to the end away from the limiting block.

[0026] By adopting the above technical solution, when the user uses it, during the process that the moving frame drives the positioning disk to move along the soot blowing screw rod, the positioning disk starts to slide along the soot blowing screw rod, the positioning block on the positioning disk can start to slide along the moving groove on the soot blowing screw rod, and the sliding inclined surface on the positioning block ensures that the positioning block can fit the thread of the soot blowing screw rod when moving in the moving groove. The sliding inclined surface of the positioning block can slide over the thread of the soot blowing screw rod, preventing the positioning block from being stuck with the thread of the soot blowing screw rod and ensuring that the positioning block can move more smoothly.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The designs of the base plate one, the base plate two, the soot blowing screw rod, the driving device, the soot blowing outer tube, the soot blowing inner tube, the telescopic port, the soot blowing hole and the moving device ensure that the soot blowing outer tube can perform normal telescopic movement, and ensure that the soot blowing outer tube can perform telescopic movement while rotating, improving the cleaning area and cleaning efficiency of the soot blowing outer tube. By rotating the soot blowing screw rod to drive the soot blowing outer tube to move, it is ensured that the soot blowing outer tube can move more stably, and at the same time, the wear degree of the soot blowing screw rod and the soot blowing outer tube can be reduced, avoiding the user from frequently replacing the soot blowing screw rod;

[0043] The following will further describe the present application in detail with reference to the attached Figures 1-11 drawings.

[0044] An embodiment of the present application discloses a threaded air soot blower. Refer to Figure 1 , a threaded air soot blower includes a first base plate 1 and a second base plate 2, and a plurality of connecting frames 3 are commonly connected between the first base plate 1 and the second base plate 2.

[0045] Refer to Figure 1 and Figure 2, each connecting frame 3 includes a connecting cross-plate 31 and a connecting vertical-plate 32. Both ends of the connecting cross-plate 31 are fixedly connected to the first base plate 1 and the second base plate 2 respectively. Both ends of the connecting vertical-plate 32 are fixedly connected to the first base plate 1 and the second base plate 2 respectively. The connecting cross-plate 31 is horizontally arranged, the connecting vertical-plate 32 is vertically arranged, the connecting cross-plate 31 is fixedly connected to the connecting vertical-plate 32, and the connecting cross-plate 31 and the connecting vertical-plate 32 together form an angle steel, which is arranged along the length direction of the soot blowing threaded rod 11. When in use by the user, the structure of the angle steel increases the stability between the first base plate 1 and the second base plate 2, and increases the stability of the overall frame.

[0046] Refer to Figure 1 and Figure 3 , two upper connecting cross-plates 31 are fixedly connected with a support plate 33 together. The support plate 33 is fixedly connected to the connecting cross-plate 31 at a position close to the first base plate 1, and the support plate 33 is fixedly connected to the first base plate 1. A soot blowing threaded rod 11 is arranged between the first base plate 1 and the second base plate 2. The soot blowing threaded rod 11 is arranged along the length direction of the connecting cross-plate 31, and both ends of the soot blowing threaded rod 11 are rotatably connected to the first base plate 1 and the second base plate 2 respectively. A driving device 4 is arranged at a position above the first base plate 1. The driving device 4 includes a double-shaft motor 41 fixedly connected to the top of the support plate 33. The output shaft on the side of the double-shaft motor 41 close to the first base plate 1 is arranged along the length direction of the soot blowing threaded rod 11 and is fixedly connected with a first driving gear 42. A second driving gear 43 is rotatably connected to the side of the first base plate 1 away from the second base plate 2, and the second driving gear 43 is located directly below the first driving gear 42. The first driving gear 42 and the second driving gear 43 are jointly engaged with a driving chain 44, and one end of the soot blowing threaded rod 11 passes through the first base plate 1 and is fixedly connected to the axis position of the second driving gear 43. The output shaft on the side of the double-shaft motor 41 away from the first base plate 1 is arranged along the length direction of the soot blowing threaded rod 11 and is fixedly connected with a driving turntable 45.

[0047] When in use by the user, start the double-shaft motor 41. The double-shaft motor 41 drives the first driving gear 42 to rotate. The first driving gear 42 drives the second driving gear 43 to rotate through the driving chain 44. The second driving gear 43 drives the soot blowing threaded rod 11 to rotate, ensuring that the soot blowing threaded rod 11 can rotate normally. At the same time, the user rotates the driving turntable 45, and the driving turntable 45 can make the double-shaft motor 41 operate normally, ensuring that when a power failure occurs, the user can manually drive the soot blowing threaded rod 11 to rotate.

[0048] Refer to Figure 3 and Figure 4, there is a soot blowing outer tube 12 arranged below the soot blowing threaded rod 11, and the soot blowing outer tube 12 is arranged along the length direction of the soot blowing threaded rod 11. A soot blowing inner tube 13 is slidably connected in the soot blowing outer tube 12. The soot blowing inner tube 13 is fixedly connected to the first base plate 1 near the position of the first base plate 1, and the soot blowing inner tube 13 extends out of the first base plate 1. A telescopic opening 21 is formed in the second base plate 2 corresponding to the position of the soot blowing outer tube 12. The soot blowing outer tube 12 can extend out from the telescopic opening 21, and one end of the soot blowing outer tube 12 extending out of the telescopic opening 21 is closed. Two soot blowing holes 121 (refer to Figure 5 ) are formed in the side wall of the soot blowing outer tube 12 near its closed end, and the two soot blowing holes 121 are symmetrically arranged on the soot blowing outer tube 12.

[0049] Refer to Figure 3 and Figure 6 , the soot blowing threaded rod 11 is connected with a moving device 5. The moving device 5 includes a moving frame 51. The moving frame 51 includes two top plates 52 and two side plates 53. The two top plates 52 are horizontally arranged, the two side plates 53 are vertically arranged, both ends of the side plates 53 are fixedly connected to the two top plates 52 respectively, and the two side plates 53 are located between the two top plates 52. Both the soot blowing threaded rod 11 and the soot blowing outer tube 12 pass through the two side plates 53 of the moving frame 51. Rotation holes 531 are formed in both side plates 53 of the moving frame 51. A positioning disk 54 is rotatably connected in the rotation hole 531 corresponding to the side plate 53 on one side of the moving frame 51 close to the first base plate 1. A positioning hole 541 is formed in the positioning disk 54 corresponding to the position of the soot blowing threaded rod 11. The soot blowing threaded rod 11 passes through the positioning hole 541 of the positioning disk 54 and is threadedly connected to the positioning disk 54. Two moving grooves 111 are formed in the side wall of the soot blowing threaded rod 11 corresponding to its threaded position. The two moving grooves 111 are symmetrically arranged and both are arranged along the length direction of the soot blowing threaded rod 11. Positioning blocks 542 are fixedly connected to the positioning hole 541 of the positioning disk 54 corresponding to each moving groove 111, and the positioning blocks 542 are slidably arranged in the moving grooves 111 of the soot blowing threaded rod 11.

[0050] Refer to Figure 3 and Figure 6, the mobile device 5 further includes a copper sleeve 55 threadedly connected to the soot blowing screw rod 11. The copper sleeve 55 is located within the moving frame 51. The axial line of the copper sleeve 55 is arranged along the length direction of the soot blowing screw rod 11. The copper sleeve 55 is fixedly connected to the side plate 53 of the moving frame 51 close to one side of the base plate 1. The soot blowing screw rod 11 is threadedly connected with a driving gear 14. The driving gear 14 is located within the moving frame 51 and is between the positioning disk 54 and the copper sleeve 55. The driving gear 14 is provided with a threaded hole 141, and the driving gear 14 is threadedly connected to the soot blowing screw rod 11 through the threaded hole 141. Two limiting blocks 142 are fixedly connected within the threaded hole 141 of the driving gear 14. The two limiting blocks 142 are symmetrically arranged on the driving gear 14. The limiting blocks 142 are slidably arranged within the moving groove 111 of the soot blowing screw rod 11, and the driving gear 14 is rotatably connected to the copper sleeve 55. A driven gear 122 is fixedly connected to the side wall of the soot blowing outer tube 12. The driven gear 122 is located within the moving frame 51, and the driving gear 14 and the driven gear 122 are meshed with each other.

[0051] When the user uses it, when the soot blowing screw rod 11 rotates, it drives the copper sleeve 55 to move along the soot blowing screw rod 11. The copper sleeve 55 drives the moving frame 51 to move, and the moving frame 51 drives the soot blowing outer tube 12 to move towards the telescopic port 21 and makes the soot blowing outer tube 12 extend out of the telescopic port 21, ensuring that the soot blowing outer tube 12 can perform normal telescopic movement. When the copper sleeve 55 moves, it drives the driving gear 14 to move along the moving groove 111 of the soot blowing screw rod 11 through the limiting blocks 142. At the same time, the driving gear 14 rotates. When the driving gear 14 rotates, it drives the driven gear 122 to rotate, and the driven gear 122 drives the soot blowing outer tube 12 to rotate, ensuring that the soot blowing outer tube 12 can also rotate during the telescopic process, improving the cleaning area and cleaning efficiency of the soot blowing outer tube 12. The rotation of the soot blowing screw rod 11 prevents the soot blowing outer tube 12 from moving unstably. The wear between the soot blowing screw rod 11 and the copper sleeve 55 is relatively small, and the user does not need to frequently replace the soot blowing screw rod 11.

[0052] Refer to Figure 6 and Figure 7, two sliding inclined surfaces 543 are provided on both sides of each positioning block 542. The two sliding inclined surfaces 543 are symmetrically arranged on the positioning block 542. The two sliding inclined surfaces 543 on the side far from the limiting block 142 are arranged in a direction away from each other from the end far from the limiting block 142 to the end close to the limiting block 142. The two sliding inclined surfaces 543 on the side close to the limiting block 142 are arranged in a direction away from each other from the end close to the limiting block 142 to the end far from the limiting block 142. When the user uses it, when the moving frame 51 drives the positioning disk 54 to move along the soot blowing screw rod 11, the positioning disk 54 slides along the soot blowing screw rod 11. The positioning block 542 on the positioning disk 54 can slide along the moving groove 111 on the soot blowing screw rod 11. The sliding inclined surface 543 ensures that the positioning block 542 can fit the thread of the soot blowing screw rod 11 when moving in the moving groove 111. The inclined surface of the positioning block 542 can slide over the thread of the soot blowing screw rod 11, ensuring that the positioning block 542 moves more smoothly.

[0053] Refer to Figure 8 and Figure 9 , two support frames 6 are fixedly connected to the top plate 52 at the bottom of the moving frame 51. The two support frames 6 are respectively fixedly connected to the two ends of the top plate 52 corresponding to its own length direction. The support frame 6 is arranged along the length direction of the connecting cross plate 31. The support frame 6 includes a support cross plate 61 and a support vertical plate 62. The support cross plate 61 is horizontally arranged, and the support vertical plate 62 is vertically arranged. The support cross plate 61 is fixedly connected to the top plate 52, and the support vertical plate 62 is fixedly connected to the end of the support cross plate 61 far from the top plate 52. Support gears 63 are rotatably connected to the mutually remote sides of the two support vertical plates 62. The support gears 63 are rotatably connected to the position of the support vertical plates 62 far from the base plate 1. The axial line of the support gear 63 is perpendicular to the soot blowing screw rod 11, and the axial line of the support gear 63 is horizontally arranged. A plurality of running grooves 311 are provided on both of the connecting cross plates 31 at the lower positions. The running grooves 311 are arranged in an array along the length direction of the connecting cross plate 31. The tooth blocks of the support gears 63 can extend into the running grooves 311. Limiting wheels 64 are rotatably connected to the positions corresponding to the support gears 63 at the top of each support cross plate 61. The axial line of the limiting wheel 64 is perpendicular to the soot blowing screw rod 11, and the axial line of the limiting wheel 64 is vertically arranged. The two limiting wheels 64 respectively abut against the two connecting vertical plates 32 at the lower positions and can roll along the connecting vertical plates 32.

[0054] When the user is using it, when the moving frame 51 moves, it drives the support frame 6 to move along the length direction of the connecting frame 3. The support gear 63 meshes with the running groove 311 of the connecting cross plate 31. The support cross plate 61 drives the support gear 63 to roll on the connecting cross plate 31. The support frame 6 drives the limit wheel 64 to roll on the connecting vertical plate 32. The support gear 63 and the limit wheel 64 support the support frame 6 and the moving frame 51, ensuring that the moving frame 51 can move normally and stably, and at the same time reducing the friction between the moving frame 51 and the connecting frame 3.

[0055] Refer to Figure 9 and Figure 10 As shown in FIGS. and, at each position of the mutually approaching sides of the two connecting cross plates 31 corresponding to its respective running grooves 311, rotating grooves 312 are provided. The rotating grooves 312 communicate with the running grooves 311, and the rotating grooves 312 and the running grooves 311 correspond one by one. A plurality of brushing devices 36 are provided on the two connecting cross plates 31 located at the lower positions. The brushing device 36 includes a rotating rod 34 connected to the corresponding rotating groove 312 of the connecting cross plate 31. The rotating rods 34 are arranged in an array along the length direction of the connecting cross plate 31. The rotating rods 34 are arranged along the width direction of the connecting cross plate 31. One end of the rotating rod 34 extends into the running groove 311 of the connecting cross plate 31, and the support gear 63 can abut against the rotating rod 34. A rotating shaft 65 is fixedly connected to the inside of each rotating groove 312 of the connecting cross plate 31. The rotating shaft 65 is arranged along the length direction of the connecting cross plate 31. The rotating rod 34 is rotatably connected to the rotating shaft 65. When the support gear 63 abuts against the rotating rod 34, the rotating rod 34 can rotate around the rotating shaft 65. A brush plate 35 is fixedly connected to one end of each rotating rod 34 away from the rotating shaft 65. The brush plate 35 is inclined upward from the end close to the rotating rod 34 to the end away from the rotating rod 34. The brush plate 35 can abut against the soot blowing outer tube 12.

[0056] When the user is using it, when the support frame 6 drives the support gear 63 to move, as the support gear 63 rotates, the rack of the support gear 63 can sequentially enter the running groove 311. The rack of the support gear 63 can abut against the rotating rod 34 and press the rotating rod 34. The rotating rod 34 rotates around the rotating shaft 65. The rotating rod 34 drives the brush plate 35 to move. The brush plate 35 abuts against the soot blowing outer tube 12 and brushes it. A plurality of rotating rods 34 and brush plates 35 are sequentially lifted as the support gear 63 moves. The brush plate 35 can brush the soot blowing outer tube 12, ensuring that the furnace ash and impurities adhering to the soot blowing outer tube 12 can be cleaned in time, ensuring the cleanliness of the surface of the soot blowing outer tube 12, and extending the service life of the soot blowing outer tube 12.

[0057] Refer to Figure 8 and Figure 11, on one side of the second base plate 2 close to the first base plate 1, two support blocks 22 are fixedly connected. The two support blocks 22 are fixedly connected to the second base plate 2 at a position close to the telescopic opening 21. The two support blocks 22 are both located below the soot blowing outer tube 12. The two support blocks 22 are both inclined downward from the end far away from the soot blowing outer tube 12 to the end close to the soot blowing outer tube 12. A rotating bead 23 is rotatably connected to one side of each support block 22 close to the soot blowing outer tube 12, and the rotating bead 23 abuts against the soot blowing outer tube 12. When the user uses it, the rotating bead 23 can rotate along with the movement of the soot blowing outer tube 12, reducing the friction force, ensuring that the soot blowing outer tube 12 moves more smoothly, and reducing the wear of the second base plate 2 on the soot blowing outer tube 12.

[0058] The implementation principle of a threaded air soot blower in an embodiment of the present application is as follows: When the user uses it, the double-shaft motor 41 is started. The double-shaft motor 41 drives the first driving gear 42 to rotate. The first driving gear 42 drives the second driving gear 43 to rotate through the driving chain 44. The second driving gear 43 drives the soot blowing threaded rod 11 to rotate. During the rotation of the soot blowing threaded rod 11, the copper sleeve 55 and the moving frame 51 slide along the soot blowing threaded rod 11 along with the rotation of the soot blowing threaded rod 11. When the copper sleeve 55 moves, it drives the driving gear 14 to move along the length direction of the soot blowing threaded rod 11. At the same time, the limiting block 142 of the driving gear 14 can slide in the moving groove 111 of the soot blowing threaded rod 11. At the same time, the driving gear 14 rotates on the soot blowing threaded rod 11. The driven gear 122 rotates together with the driving gear 14. The driven gear 122 drives the soot blowing outer tube 12 to rotate. While the soot blowing outer tube 12 rotates, it extends towards the telescopic opening 21 and extends out from the telescopic opening 21, ensuring that the soot blowing outer tube 12 can perform normal telescopic movement while also being able to rotate, improving the cleaning area and cleaning efficiency of the soot blowing outer tube 12. The rotation of the soot blowing threaded rod 11 can drive the movement of the soot blowing outer tube 12, avoiding the situation of unstable movement of the soot blowing outer tube 12.

[0059] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
