Description

Technical Field

[0001] The invention relates to the technical field of steam boilers and discloses an energy-saving boiler with a sootblowing device. Background Art

[0002] In terms of industrial production and domestic water use, steam boilers are key equipment for generating steam or hot water and are widely used in various fields. Steam boilers heat water by burning fuel (such as coal, oil, natural gas, etc.) or other heat sources to make the water reach boiling point and convert it into steam. Therefore, steam boilers can be divided into: coal-fired boilers, oil-fired boilers, gas-fired boilers, etc.

[0003] Existing coal-fired boilers are usually composed of a furnace, a burner, a heat exchange water pipe, etc. The burner and the heat exchange water pipe are both located inside the furnace. When the coal-fired boiler is in use, coal is first placed in the furnace, and the burner burns the coal to generate high-temperature flames and flue gas in the furnace. Subsequently, water is injected into the heat exchange water pipe, and heat is exchanged between the high-temperature flue gas in the furnace and the heat exchange water pipe, thereby heating the water in the heat exchange water pipe, heating the water in the heat exchange water pipe into steam, and finally spraying it out from the heat exchange water pipe, thereby completing the preparation of steam.

[0004] However, during the use of coal-fired boilers, unstable fuel supply will cause the temperature inside the boiler to fluctuate. When the temperature inside the boiler rises, the water inside the water exchange pipe will heat up faster, which will convert more water into steam. If the excess steam cannot be used in time, in order to maintain a safe working pressure, the excess steam will be discharged directly into the atmosphere through the exhaust pipe. This process not only causes significant energy losses, but also increases greenhouse gas emissions, violating the principles of energy conservation and emission reduction. Summary of the invention

The two guide pipes 5 on the same connecting pipe 4 are respectively rotatably connected and connected to the water inlet guide shell 7 and the air guide shell 8.

[0057] In the above scheme, the furnace body 1 is an existing steam boiler, and the furnace body 1 is provided with a feed port for adding coal into the furnace body 1. The lower side of the furnace body 1 is connected with an air inlet pipe for replenishing oxygen into the furnace body 1. The upper side of the furnace body 1 is connected with an exhaust pipe for discharging the flue gas in the furnace body 1. The heat exchange components can be provided in multiples according to the volume of the furnace body 1. Four are taken as an example in the figure, and one is described later. The connecting pipe 4 and the guide pipe 5 are both made of metal with high thermal conductivity and high temperature resistance (can be stainless steel). The water inlet guide shell 7 is connected with a water supply pipe for supplying water to the water inlet guide shell 7.

[0058] See also Figure 2 and Figure 4-Figure 6 The heat exchange component also includes: fixed rods 3, the number of which is consistent with the number of connecting pipes 4, both of which are fixedly connected to the furnace cover 2, and the fixed rods 3 are fixedly connected to the adjacent connecting pipes 4; branch pipes 6, the number of which is consistent with the number of guide pipes 5, respectively fixedly connected to the adjacent guide pipes 5, and both sides of the branch pipes 6 are connected to the guide pipes 5; a soot blowing component, which is arranged on the furnace cover 2 and is used to clean the dust on the guide pipes 5; a driving component, which is arranged on the furnace cover 2 and is used to drive the guide pipes 5 to rotate.

[0059] In the above scheme, the fixing rod 3 is used to improve the stability of the connecting pipe 4, the branch pipe 6 is made of a metal material with high thermal conductivity and high temperature resistance (can be stainless steel), the guide pipe 5 is composed of an inlet section, a throat and an outlet section, one side of the branch pipe 6 is connected to the connection between the inlet section and the throat of the guide pipe 5, and the other side of the branch pipe 6 is connected to the connection between the throat and the outlet section of the guide pipe 5. The flow volume of the throat of the guide pipe 5 is half of the flow volume of the inlet section and the outlet section of the guide pipe 5, and the flow volume of the branch pipe 6 is consistent with the flow volume of the throat of the guide pipe 5.

[0060] See also Figure 1 , Figure 6 , Figure 7 , Fig. 9 and Fig.12 The sootblowing assembly includes: a support frame 9, which is installed on the furnace cover 2, and the support frame 9 is slidably connected with a moving module 10, and the moving module 10 is provided with an electric rotating shaft; an air blowing pipe 11, which is fixedly connected to the electric rotating shaft of the moving module 10, and the air blowing pipe 11 passes through the furnace cover 2 and is sealed and slidably connected with the furnace cover 2, and a blowing port is opened on the side of the air blowing pipe 11 away from the moving module 10, and the support frame 9 is fixedly connected with an air guide pipe 12, which passes through the moving module 10 and is sealed and slidably connected with the air blowing pipe 11, and the air guide pipe 12 is located inside the air blowing pipe 11.

[0061] In the above scheme, when the number of heat exchange components increases, the number of soot blowing components increases accordingly. The movable module 10 is used to drive the air blowing pipe 11 to move up and down. The electric shaft of the movable module 10 is used to drive the air blowing pipe 11 to rotate. The air guide pipe 12 is connected to the air supply pipe. The air supply pipe of the air guide pipe 12 is connected to the external air supply device. The air port of the air blowing pipe 11 is set to at least two, and the air port of the air blowing pipe 11 is used to guide the high-pressure steam in the air blowing pipe 11.

[0062] See also Figure 1 , Figure 2 and Figure 4-Figure 7 The driving assembly includes: a reversing module 13, which is installed on the furnace cover 2. The input shaft of the reversing module 13 is fixedly connected with a rotating wheel 14. The reversing module 13 is located between the two guide tubes 5 of the same connecting pipe 4. The output shaft of the reversing module 13 is transmission-connected with the two guide tubes 5 on the same connecting pipe 4. The two guide tubes 5 connected with the water inlet guide shell 7 are transmission-connected through a transmission member, and the two guide tubes 5 connected with the air guide shell 8 are transmission-connected through a transmission member; a transmission rod 15 is fixedly connected to the moving module 10. The transmission rod 15 passes through the furnace cover 2 and is sealingly and slidingly connected with the furnace cover 2. The transmission rod 15 is transmission-connected with the rotating wheel 14.

[0063] In the above scheme, when the number of heat exchange components increases, the number of driving components increases accordingly. The reversing module 13 is an existing reversing transmission. The rotation of the input shaft of the reversing module 13 can drive the output shaft of the reversing module 13 to rotate reciprocatingly. The transmission methods between the reversing module 13 and the two guide tubes 5 on the same connecting tube 4 are gear reversing transmission and belt and pulley unidirectional transmission, which are used to make the rotation directions of the two guide tubes 5 on the same connecting tube 4 opposite. The transmission parts between two adjacent guide tubes 5 on different connecting tubes 4 are belt and pulley unidirectional transmission, and the transfer rod 15 drives the rotating wheel 14 to rotate through friction.

[0064] When using the device to make steam, the staff adds coal into the furnace body 1 and starts the burner, ignites the coal through the burner, and heats the guide pipe 5 and the connecting pipe 4 through the high-temperature flue gas generated by the combustion of the coal. Then, water is sent to the water inlet guide shell 7 through the external water pumping device. The water flow to be heated flows through the guide pipe 5 on the water inlet guide shell 7 to the connecting pipe 4. In the process of the water flow passing through the guide pipe 5 and the connecting pipe 4, the water flow exchanges heat with the heat in the furnace body 1, so that the water flow is heated, thereby heating the water flow. When the water flow passes through the inlet section of the guide pipe 5 on the water inlet guide shell 7 and enters the throat of the guide pipe 5, since the flow rate of the throat of the guide pipe 5 is less than the flow rate of the inlet section of the guide pipe 5, a part of the water flow will enter the branch pipe 6 at this time. The water flow entering the branch pipe 6 also exchanges heat with the heat in the furnace body 1. The water flow entering the branch pipe 6 enters the outlet section of the guide pipe 5 after passing through the entire branch pipe 6, and is finally discharged into the connecting pipe 4 through the outlet section of the guide pipe 5.

[0065] When the water flows through the connecting pipe 4 and enters the guide pipe 5 of the air guide shell 8, the water flows into the guide pipe 5 and is also divided into the throat and branch pipe 6 of the guide pipe 5. At this time, the water in the throat and branch pipe 6 of the guide pipe 5 on the air guide shell 8 is evaporated into steam. The evaporated steam passes through the throat and branch pipe 6 of the guide pipe 5, and finally converges through the outlet section of the guide pipe 5 and is discharged through the air guide shell 8. The steam entering the air guide shell 8 is transported to the desired location through the exhaust pipe thereon. The guide pipe 5 is vertically arranged, thereby increasing the contact area between the high-temperature flue gas and the guide pipe 5. At the same time, the branch pipe 6 is used to increase the contact area between the water flow and the heat in the furnace body 1, thereby improving the heat utilization rate in the furnace body 1.

[0066] During the process of conveying steam by the air guide shell 8 and the exhaust pipe thereon, when the temperature in the furnace body 1 rises, the water in the guide pipe 5, the branch pipe 6 and the connecting pipe 4 is quickly heated, so that the steam production rate is increased, which will cause the pressure in the air guide shell 8 and the exhaust pipe thereon to increase. At this time, the first pressure relief valve in the first intermediate pipe 203 is opened, and part of the steam in the exhaust pipe on the air guide shell 8 enters the air storage shell 201 through the first intermediate pipe 203. The steam entering the air storage shell 201 pushes the sliding plate 202 to move upward and compresses the elastic telescopic rod on the air storage shell 201. The air storage shell 201 is used to temporarily store excess steam, so that the pressure in the air guide shell 8 and the exhaust pipe thereon remains stable. When the temperature in the furnace body 1 decreases, the steam production rate slows down, the pressure in the air guide shell 8 and the exhaust pipe thereon decreases, and the first pressure relief valve in the first intermediate pipe 203 is closed.

[0067] After the first pressure relief valve in the first intermediate pipe 203 is closed, the elastic telescopic rod on the gas storage shell 201 is reset under the action of its own elastic force and drives the sliding plate 202 to move downward. The sliding plate 202 moves downward to push the steam in the gas storage shell 201 into the exhaust pipe of the gas guide shell 8 through the second intermediate pipe 204 and the one-way valve therein, and stops until the elastic telescopic rod of the gas storage shell 201 is completely reset. Then, the above action is repeated when the temperature in the furnace body 1 changes again. The gas storage shell 201 stores the steam in the exhaust pipe of the gas guide shell 8, thereby avoiding direct discharge of excess steam into the air, reducing steam loss and achieving the purpose of energy saving.

[0068] During the process of steam in the exhaust pipe of the air guide shell 8 entering the air storage shell 201, before the steam pressure in the air storage shell 201 reaches the limit pressure that the air storage shell 201 can withstand, the second pressure relief valve on the air storage shell 201 opens to discharge excess steam into the air, thereby preventing the pressure in the air storage shell 201 from being too high and causing damage to the air storage shell 201 and the first intermediate pipe 203 and the second intermediate pipe 204, thereby extending the service life of the air storage shell 201.

[0069] In the process of using the present device for steam supply, as the flue gas rises, the small particles that are not completely burned in the flue gas will adhere to the surface of the guide pipe 5 and the branch pipe 6. The small particles on the surface of the guide pipe 5 and the branch pipe 6 (hereinafter referred to as fly ash) will isolate part of the heat, thereby reducing the heat conduction efficiency of the guide pipe 5 and the branch pipe 6. At this time, the staff starts the mobile module 10 and simultaneously transmits high-pressure steam into the air guide pipe 12 through the external air supply device. After the mobile module 10 is started, it moves downward along the support frame 9 and drives the parts thereon to move synchronously. In this process, the electric shaft of the mobile module 10 drives the air blowing pipe 11 to rotate, so that the air blowing pipe 11 rotates synchronously when moving downward, and the air blowing pipe 11 and the air guiding pipe 12 slide relative to each other. In the process of the air blowing pipe 11 moving downward, the high-pressure steam in the air guiding pipe 12 enters the air blowing pipe 11 and is ejected through the air port of the air blowing pipe 11, thereby cleaning the fly ash on the surface of the guide pipe 5 and the branch pipe 6.

[0070] During the downward movement of the mobile module 10, the transfer rod 15 drives the rotating wheel 14 to rotate through friction, and the rotation of the rotating wheel 14 drives the input shaft of the reversing module 13 to rotate, and finally the output shaft of the reversing module 13 rotates back and forth, and the output shaft of the reversing module 13 rotates through the gears and pulleys thereon to respectively drive the two adjacent guide pipes 5 to rotate. At this time, the rotation directions of the two guide pipes 5 on the same connecting pipe 4 are opposite, so that the guide pipe 5 drives the branch pipes 6 thereon to swing in a direction close to each other, and the rotation of the guide pipe 5 drives the adjacent guide pipes 5 to rotate through the transmission parts thereon, and finally the four branch pipes 6 are all swung toward a common center point. During the reciprocating rotation of the output shaft of the reversing module 13, the guide pipe 5 also rotates back and forth and drives the branch pipes 6 to swing back and forth, and so on.

[0071] During the reciprocating rotation of the guide pipe 5, the high-pressure steam blown out from the blowing pipe 11 continuously cleans the fly ash on the surface of the guide pipe 5 and the branch pipe 6. The reciprocating rotation of the guide pipe 5 is used to increase the cleaning area of ​​the guide pipe 5 and the branch pipe 6, thereby improving the cleaning effect of the guide pipe 5 and the branch pipe 6. After the mobile module 10 drives the blowing pipe 11 to move the blowing port of the blowing pipe 11 to the lower side of the connecting pipe 4 and cleans the connecting pipe 4, the staff controls the mobile module 10 to move upward. During the upward movement of the mobile module 10, the transfer rod 15 drives the rotating wheel 14 to reverse by friction, and the guide pipe 5 and the branch pipe 6 continue to rotate. The blowing pipe 11 also cleans the guide pipe 5 and the branch pipe 6 until the mobile module 10 moves and resets. The staff closes the mobile module 10 and the external gas supply device at the same time. After the mobile module 10 stops, the rotating wheel 14 stops rotating, and the guide pipe 5 and the branch pipe 6 are reset. Thereafter, the above-mentioned actions are repeated when the guide pipe 5 and the branch pipe 6 need to be cleaned again.

[0072] Example 2: Based on Example 1, please refer to Figure 7 , Fig. 9 and Fig.10 , also includes an air guide component, which is arranged in the air blowing pipe 11 and is used to change the blowing direction of the air blowing pipe 11. The air guide component includes: a plurality of rotating blocks 16, which are all sealed and rotatably connected to the air blowing pipe 11. The rotating blocks 16 are provided with through holes. The through holes of the rotating blocks 16 connect the inside of the air blowing pipe 11 with the outside. A first elastic member 1601 is fixedly connected between the rotating block 16 and the air blowing pipe 11.

[0075] In the above scheme, the extrusion block 1702 is composed of a rectangular plate and an arc block. The rectangular plate of the extrusion block 1702 slides in the first fixed shell 17. The arc block of the extrusion block 1702 is used to extrude the elastic tube 1701. The elastic tube 1701 is made of a high temperature resistant material (which can be silicone rubber). The extrusion block 1702 extrudes the elastic tube 1701 to reduce the inner diameter of the elastic tube 1701, thereby increasing the gas flow rate through the elastic tube 1701. Several extrusion blocks 1702 are evenly distributed circumferentially to ensure that the extrusion block 1702 evenly extrude the elastic tube 1701.

[0076] See also Figure 9-11 , and also includes: first rotating rings 1703, the number of which is the same as the number of first fixed shells 17, and are respectively rotatably connected to the outer peripheral sides of adjacent first fixed shells 17, and a sliding groove is opened on the peripheral side of the first fixed shell 17. The first rotating ring 1703 is fixedly connected to the first fixed shell 17 through the sliding groove of the first fixed shell 17 with a second elastic member 1704. The second elastic member 1704 is located between the adjacent first fixed shell 17 and the adjacent extrusion block 1702, and the second elastic member 1704 is used to squeeze the adjacent extrusion block 1702.

[0077] In the above scheme, the first rotating ring 1703 is composed of a circular ring and a T-shaped block. The T-shaped block of the first rotating ring 1703 is slidably connected to the slide groove of the first fixed shell 17. The second elastic member 1704 is fixedly connected to the T-shaped block of the first rotating ring 1703. The second elastic member 1704 is configured as a torsion spring. When the second elastic member 1704 is subjected to torque, its inner diameter will shrink.

[0078] See also Figure 6 and Figure 12-14 , also includes: a second fixed shell 18, fixedly connected to the mobile module 10, the air blowing pipe 11 passes through the second fixed shell 18 and is rotatably connected to the second fixed shell 18, a second rotating ring 19 is slidably connected in the second fixed shell 18, the second rotating ring 19 is spline-connected to the air blowing pipe 11, the second rotating ring 19 is rotatably connected to the third rotating ring 20, a pull rope 22 is fixedly connected between the first rotating ring 1703 and the second rotating ring 19, and the pull rope 22 is located in the side wall of the air blowing pipe 11; a sliding column 23, slidably connected to the second fixed shell 18, and a third elastic member 24 is fixedly connected between the two, and the sliding column 23 is fixedly connected to the third rotating ring 20.

[0079] In the above scheme, the second rotating ring 19 is used to pull the pull rope 22 to move, the sliding column 23 is used to drive the third rotating ring 20 to move, the second rotating ring 19 is spline-connected to the blowing tube 11, and the second rotating ring 19 and the blowing tube 11 rotate synchronously, so that the second rotating ring 19 can only pull the third rotating ring 20 to move upward, the pull rope 22 is used to pull the first rotating ring 1703 to rotate, the pull rope 22 is made of high temperature resistant material (can be a stainless steel wire rope), and the third elastic member 24 is set as a spring, which is used to drive the sliding column 23 to reset.

[0080] See also Figure 4-Figure 8 , and also includes: a reduction module 25, which is installed on the furnace cover 2, the input shaft of the reduction module 25 is fixedly connected to the rotating wheel 14, the reduction module 25 is fixedly connected to a third fixed shell 26, and an L-shaped rod 27 is slidably connected in the third fixed shell 26, and the L-shaped rod 27 is located on the moving path of the moving module 10; a wire sleeve 28, which is fixedly connected between the third fixed shell 26 and the second fixed shell 18, and a wire core 29 is slidably connected in the wire sleeve 28, one side of the wire core 29 is fixedly connected to the sliding column 23, and the other side of the wire core 29 is fixedly connected to the output shaft of the reduction module 25, and the L-shaped rod 27 is used to squeeze the wire core 29.

[0081] In the above scheme, the reduction module 25 is an existing reducer, and the rotating wheel 14 drives the input shaft of the reduction module 25 to rotate, so that the output shaft of the reduction module 25 rotates slowly. The output shaft of the reduction module 25 can be fixedly connected with a rotating wheel, and the wire core 29 is fixedly connected to the output shaft of the reduction module 25 through the rotating wheel. The L-shaped rod 27 is provided with an inclined surface on the side close to the wire core 29, so that when the L-shaped rod 27 squeezes the wire core 29, the wire core 29 can bend smoothly, and the distance between the two connecting tubes 4 in the horizontal direction gradually increases from bottom to top.

[0082] See also Fig. 9 and Fig.10 , and further includes: protrusions 30, the number of which is the same as the number of rotating blocks 16, which are respectively fixed to adjacent rotating blocks 16, and arc-shaped slideways 31 with the same number as the protrusions 30 are provided in the blowing pipe 11, and the protrusions 30 slide in the adjacent arc-shaped slideways 31.

[0083] In the above scheme, the center line of the arc slide 31 projected on the horizontal plane is a straight line, and the straight line is perpendicular to the axis of the blowing tube 11. The arc slide 31 limits the rotating block 16 through the protrusion 30, so that the rotating block 16 can only swing up and down, thereby improving the stability of the rotating block 16 during rotation.

[0084] In the process of the air blowing pipe 11 moving downward to clean the guide pipe 5 and the branch pipe 6, the rotating wheel 14 rotates to drive the input shaft of the reduction module 25 to rotate continuously, so that the output shaft of the reduction module 25 rotates slowly. The output shaft of the reduction module 25 rotates, so that the wire core 29 is gradually wound around the output shaft of the reduction module 25, thereby pulling the wire core 29 to slide in the wire sleeve 28. The wire core 29 pulls the third rotating ring 20 to move upward through the sliding column 23, and at the same time, the third elastic member 24 is gradually compressed. The movement of the third rotating ring 20 drives the second rotating ring 19 to move upward (in the process of the air blowing pipe 11 rotating, the air blowing pipe 11 and the second fixed shell are 18 rotates relative to each other, and at the same time, the air blowing tube 11 drives the second rotating ring 19 to rotate synchronously, and the second rotating ring 19 and the third rotating ring 20 rotate relative to each other), the second rotating ring 19 moves to pull the pull rope 22 to slide in the air blowing tube 11, and the pull rope 22 pulls the first rotating ring 1703 to rotate, and the first rotating ring 1703 rotates to make the second elastic member 1704 accumulate force. The inner diameter of the second elastic member 1704 decreases when accumulating force, so that the second elastic member 1704 squeezes the squeezing block 1702, and the squeezing block 1702 moves toward the axial direction of the first fixed shell 17 after being squeezed, and finally the squeezing block 1702 squeezes the elastic tube 1701.

[0085] The inner diameter of the elastic tube 1701 is squeezed and reduced. When the high-pressure steam in the blowing pipe 11 passes through the through hole of the rotating block 16 and the elastic tube 1701 with a reduced inner diameter, the flow rate of the high-pressure steam blown out of the blowing pipe 11 is increased. In the process of the blowing pipe 11 continuously moving downward, the inner diameter of the elastic tube 1701 is gradually reduced, so that the flow rate of the high-pressure steam in the blowing pipe 11 is gradually increased, thereby gradually increasing the impact force of the high-pressure steam in the blowing pipe 11 on the guide pipe 5 and the branch pipe 6, increasing the cleaning force in the area where more fly ash is attached to the lower part of the guide pipe 5 and the branch pipe 6, and improving the cleaning effect of the guide pipe 5 and the branch pipe 6.

[0086] When the first fixed shell 17 moves to the horizontal position of the connecting pipe 4, the high-pressure steam blown out from the elastic tube 1701 first cleans the fly ash on the upper side of the connecting pipe 4. When the elastic tube 1701 moves to the horizontal lower position of the connecting pipe 4, the second elastic member 1704 is twisted to the limit state, and the L-shaped rod 27 is squeezed by the moving module 10 and displaced downward. The L-shaped rod 27 moves to squeeze the wire core 29, causing the wire core 29 to bend. Since the input shaft of the speed reduction module 25 cannot overcome the gap between the transmission rod 15 and the rotating wheel 14, the second elastic member 1704 is twisted to the limit state. The friction force causes the bending of the wire core 29 to fail to drive the output shaft of the deceleration module 25 to reverse, so that the wire core 29 quickly pulls the sliding column 23 upward and further compresses the third elastic member 24. The sliding column 23 moves through the third rotating ring 20 and the second rotating ring 19 to pull the pull rope 22 to move quickly. At this time, the second elastic member 1704 is twisted to the limit state, and the pull rope 22 applies an upward pulling force to the first fixed shell 17 through the first rotating ring 1703, so that the first fixed shell 17 drives the rotating block 16 to rotate upward.

[0087] When the rotating block 16 rotates, it drives the protrusion 30 to slide in the arc-shaped slideway 31 and stretches the first elastic member 1601, and finally makes the elastic tube 1701 tilt upward from the side close to the rotating block 16 to the side away from the rotating block 16, so that the high-pressure steam blown out from the elastic tube 1701 cleans the fly ash on the oblique lower side of the connecting pipe 4, thereby completely cleaning the connecting pipe 4 and improving the cleaning completeness of the connecting pipe 4. After the cleaning of the connecting pipe 4 is completed, during the upward movement of the moving module 10, the moving module 10 first releases the squeezing of the L-shaped rod 27, and the elastic force of the third elastic member 24 is first released partially and drives the sliding column 23 to move downward, and the sliding column 23 moves to pull the wire core 29, so that the bent part of the wire core 29 is straightened, and the straightening of the wire core 29 drives the L-shaped rod 27 to move upward and reset.

[0088] The sliding column 23 moves through the third rotating ring 20 to drive the second rotating ring 19 to move downward, so that the second rotating ring 19 first releases part of its pulling force on the pull rope 22, so that the pulling force of the first elastic member 1601 can be released. The pulling force release of the first elastic member 1601 drives the rotating block 16 to rotate and reset. At the same time, the protrusion 30 slides and resets in the arc slide 31. The rotating block 16 rotates and resets, driving the first fixed shell 17 to reset. Subsequently, in the process of the blowing tube 11 gradually moving upward, the transfer rod 15 drives the rotating wheel 14 to rotate in the opposite direction. The rotating wheel 14 drives the output shaft of the reduction module 25 to rotate in the opposite direction through the input shaft of the reduction module 25, so that the output shaft of the reduction module 25 releases the wire core 29 wound thereon.

[0089] After the wire core 29 is released, the sliding column 23 gradually moves and resets under the elastic force of the third elastic member 24 and pulls the wire core 29 to gradually reset. The sliding column 23 is reset and drives the second rotating ring 19 to move downward and reset through the third rotating ring 20, so that the second rotating ring 19 releases the pulling force on the pull rope 22, and the pulling force of the pull rope 22 on the first rotating ring 1703 is released. The second elastic member 1704 is reset under the action of its own torque and drives the first rotating ring 1703 to reset. The reset of the first rotating ring 1703 pulls the pull rope 22 to reset. At the same time, the second elastic member 1704 releases the squeezing of the squeezing block 1702, and the squeezing block 1702 releases the squeezing of the elastic tube 1701. The elastic tube 1701 is reset under the action of its own elasticity and pushes the squeezing block 1702 to move and reset. The air blowing pipe 11 stops after moving upward and resetting. The subsequent air blowing pipe 11 repeats the above action when cleaning the guide pipe 5 and the branch pipe 6 again.
