Abstract
Description
Technical Field
[0001] This invention relates to the field of pneumatic pipeline conveyor technology, specifically to an automatic transport and processing device for slag from a heating furnace used in the production of magnesium-calcium bricks. Background Technology
[0002] The slag conveying method for the heating furnace in magnesia-calcium brick production is pneumatic pipeline conveying. The process of conveying slag mainly relies on pneumatic conveying technology, using compressed air or vacuum pressure to transport the slag to a designated location. Pneumatic conveying utilizes airflow to propel slag particles through a closed pipeline, with the air pressure or vacuum pressure generated by a blower driving the material's movement. When the airflow velocity reaches a certain value, the slag particles are agitated, and the slag flows with the airflow, forming a fluidized conveying state.
[0003] A pneumatic pipeline conveyor includes a conveying pipeline and an air blowing source installed above the feed port of the conveying pipeline. Slag falls in a conical hopper and then arrives at the feed end of the pipeline. The airflow directly blows the slag into the conveying pipeline. The slag is transported in the pipeline with the airflow and finally discharged at the discharge end of the pipeline. In this way, the slag is transported quickly in two sections. If the pipeline path is short, the slag can be transported smoothly. However, if the conveying pipeline path is long, relying solely on the work of the air blowing source may not be able to effectively transport the slag to the end of the pipeline. The airflow will be weak, that is, the slag is transported quickly in the initial area of the pipeline, but the transport is slow in the latter half of the pipeline. Large or heavy slag particles may even remain in the pipeline. The slag that is transported later will be blocked by the previously retained slag, and slag will accumulate in local areas of the pipeline, thus affecting the efficient transport of slag. Although the power of the air blowing source can be increased, the air blowing source will operate at high load for a long time, which will consume a lot of energy and cause energy waste.
[0004] The conveying pipeline can be divided into multiple sections, and an independent auxiliary blowing mechanism can be installed in each section. If slag is stuck in a single section of the pipeline, the corresponding auxiliary blowing mechanism will blow air nearby to quickly blow away the accumulated slag. Since the auxiliary blowing mechanism is close to the accumulated slag, it can blow away the slag with a small blowing force, avoiding the problem of consuming blowing power over long distances. Based on the purpose of unblocking the internal pneumatic pipeline, this invention provides an automatic transport and processing device for slag from heating furnaces used in the production of magnesium-calcium bricks. Summary of the Invention
[0005] The purpose of this invention is to provide an automatic transport and processing device for slag from heating furnaces used in the production of magnesium-calcium bricks, in order to solve the problem of low slag transport efficiency mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic transport and processing device for slag from a heating furnace used in the production of magnesium-calcium bricks, comprising a conical hopper for slag collection, a downward blowing air source disposed in the conical hopper, and a conveying pipe connected to the bottom of the conical hopper. The entire section of the conveying pipe is divided into multiple unit sections, and each unit section is provided with an impact mechanism. The impact mechanism clears local blockages on the conveying pipe nearby. Multiple partial disconnection points are provided along the path of the conveying pipe, with one side of the partial disconnection point being an L-shaped drop pipe and the other side being a long horizontal pipe. The impact mechanism includes a transfer box connected between the L-shaped drop pipe and the long horizontal pipe, and an inner tube connected to one side of the transfer box. The inner tube is installed in the long horizontal pipe to detect blockages.
[0007] The inner tube device includes an inner tube suspended in a long horizontal tube, a row of U-shaped pads set in the gap between the long horizontal tube and the inner tube on one side, a long pad shaft set in the gap between the long horizontal tube and the inner tube on the other side, and a row of control components sleeved on the inner tube.
[0008] The transfer box includes a vertical box fixedly connected between an L-shaped discharge pipe and a long horizontal pipe, a U-shaped trough box fixed in the vertical box, a strong air blower set at one end of the U-shaped trough box, a connecting device set at the end of the inner pipe, and a first adapter shaft, a second adapter shaft and a motor shaft installed at the bottom of the vertical box. One end of the inner pipe is connected to the other end of the U-shaped trough box by setting an opening cylinder.
[0009] The opening cylinder on the inner tube connects with the round opening on the side of the U-shaped groove box. The round opening of the U-shaped groove box leaves space for the inner tube opening cylinder to move and shift. The outer edge of the opening cylinder on the inner tube slides in contact with the inner wall of the U-shaped groove box through a ring plate. The opening at the top of the U-shaped groove box is connected to the L-shaped discharge pipe.
[0010] A cavity is left between the upright box and the U-shaped trough box, and the first adapter shaft, the second adapter shaft, the motor shaft, the powerful fan and the connecting device are all distributed in the cavity. The upright box is equipped with a bottom frame to limit and support the first adapter shaft, the second adapter shaft and the motor shaft. The first adapter shaft and the second adapter shaft are both driven between the powerful fan and the connecting device.
[0011] The control assembly includes a control ring cylinder that is movably sleeved on the outside of the inner tube, two symmetrically distributed T-shaped rail posts on one side of the control ring cylinder, and a C-shaped spring piece with one end fixed on the control ring cylinder. The T-shaped rail posts are slidably inserted into the T-shaped grooves opened on the control ring cylinder.
[0012] The C-shaped spring supports the control ring cylinder to counteract the downward pressure from the inner tube.
[0013] The long pad shaft includes a speed-stabilizing shaft supported by a protrusion on the inner wall of the long flat tube, and a row of semi-cylindrical plates fixed on the speed-stabilizing shaft, with each semi-cylindrical plate correspondingly distributed below the control ring cylinder.
[0014] The half-tube plate limits the inner tube offset by being placed between the speed stabilizer shaft and the control ring.
[0015] The actuator includes an output shaft that drives between the speed-regulating shaft and the motor shaft, an actuator assembly that drives on one side of the output shaft, and a first slanted worm gear that engages with an external gear ring fixed on the inner tube, as well as a rear frame that simultaneously supports the output shaft, the actuator assembly, and the first slanted worm gear. The rear frame is fixed on a U-shaped slot box, and the first slanted worm gear and the first adapter shaft establish a transmission.
[0016] The actuator assembly includes a press frame that slides through the inside of a plate cylinder on the rear frame, a return spring that applies elastic force to one end of the press frame, a double-control shaft gear supported and driven on the press frame, a tail gear distributed at one end of the double-control shaft gear, and a trigger shaft that is coaxially and fixedly connected to the tail gear. The axially moving double-control shaft gear and tail gear establish meshing transmission.
[0017] The powerful fan includes a charging section with a circular opening on one side of the housing, a fan driven by the charging section, a vertical shaft that transmits power between the charging section and the first adapter shaft, and a second worm gear that transmits power between the charging section and the second adapter shaft.
[0018] Multiple one-way springs are evenly arranged around one side of the fan. Each one-way spring corresponds to a plate hole opened on the U-shaped slot box housing, and the middle of the one-way spring is fixed to the U-shaped slot box by setting a spring.
[0019] The fan rotates to blow external airflow toward the U-shaped slot, and the airflow is injected into the U-shaped slot by blowing up the one-way spring inside the U-shaped slot.
[0020] The charging unit includes a horizontal frame fixed on the vertical box, a fan shaft with limiting support in the middle of the horizontal frame, a spring assembly driven by one end of the fan shaft, a short control shaft that establishes transmission between the vertical shaft and the fan shaft, and a multi-position frame for supporting the spring assembly. The multi-position frame is fixed on the horizontal frame, and the other end of the fan shaft is fixed in the middle of the fan.
[0021] The multi-position frame simultaneously limits and supports the second inclined worm and the vertical shaft. The spring assembly collects the intermittent rotational power from the second inclined worm, and drives the fan shaft to rotate after the spring assembly is fully charged.
[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] 1. In traditional technology, if the conveying pipeline has a long conveying path, simply setting up an air blowing mechanism at the initial position of the conveying pipeline cannot guarantee continuous conveying and may result in weak air output. The further away from the air blowing source, the less impact the conveying airflow has on the slag. Therefore, this invention divides the long path of the conveying pipeline into multiple sections, and sets up a transfer box in each section to enhance the blowing. The slag is conveyed inside the inner tube. If there is any slag buildup, the transfer box will generate a new airflow to inject into the inner tube. Together with the original conveying airflow in the inner tube, a strong airflow will be generated to completely blow away and carry away the slag.
[0024] 2. The slag is transported through the inner tube. If there is slag accumulation in the inner tube, the inner tube will rotate while a strong airflow passes through it. The rotation causes the slag to move inside the inner tube. In this way, the strong airflow can more easily blow away and carry away the accumulated slag. Attached Figure Description

Detailed Implementation
[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] Please see Figures 1 to 14 The present invention provides a technical solution: an automatic transport and processing device for slag from a heating furnace used for the production of magnesium-calcium bricks, comprising a conical hopper for the slag to fall and collect, a downward blowing air source set in the conical hopper, and a conveying pipe 1 connected to the bottom end of the conical hopper. The entire section of the conveying pipe 1 is divided into multiple unit sections, and an impact mechanism 2 is set in each unit section.
[0042] Specifically, this invention innovatively develops the conveying pipeline system of the existing pneumatic conveyor, solving the problem of insufficient power when conveying slag in long-path pipelines. As the slag gradually moves away from the air blowing source in the conveying pipeline, the airflow in the pipeline gradually weakens its driving force on the slag. Once large or heavy slag particles remain in the pipeline, in order to prevent the slag from gradually accumulating and causing blockage, the impact mechanism 2 needs to provide additional blowing force to blow away the stagnant slag nearby, ensuring that the slag smoothly reaches the end of the pipeline. Multiple impact mechanisms 2 are applied to the long conveying pipeline.
[0043] Specifically, the impact mechanism 2 applies force by partially dividing the conveying pipe 1 into two sections and establishing a connection between the two sections by installing the impact mechanism 2. The impact mechanism 2 clears the local blockages on the conveying pipe 1. Multiple local disconnection points are set along the path of the conveying pipe 1, with an L-shaped drop pipe 3 on one side of the local disconnection point and a long horizontal pipe 4 on the other side. The impact mechanism 2 includes a transfer box 5 connecting the L-shaped drop pipe 3 and the long horizontal pipe 4, and an inner pipe device 6 connected to one side of the transfer box 5. The inner pipe device 6 is installed in the long horizontal pipe 4 to detect blockages.
[0044] To further understand, the overall length of the conveying pipeline 1 is divided into multiple sections. Each section includes an L-shaped material drop pipe 3 and a long horizontal pipe 4. Adjacent sections are connected end-to-end, meaning that the L-shaped material drop pipe 3 in one section is connected to the long horizontal pipe 4 in another section. The path of the L-shaped material drop pipe 3 is short, which serves the purpose of material transfer, while the path of the long horizontal pipe 4 is long, which serves the purpose of material conveying. The specific length of the inner tube device 6 is determined according to the actual situation of the long horizontal pipe 4. For example, the closer the long horizontal pipe 4 is to the initial air blowing source, the less likely it is to become blocked. The closer it is to the end of the conveying pipeline 1, the more likely it is to cause slag retention and accumulation. The inner tube device 6 basically needs to cover the entire path of the long horizontal pipe 4.
[0045] The slag transported from the long horizontal pipe 4 flows through the inner tube device 6. The inner tube device 6 detects whether there is too much slag inside. If there is too much slag, the inner tube device 6 moves the accumulated slag by rotating the pipe. The moved slag can be more easily carried away by the passing airflow. At the same time, the transfer box device 5 will quickly inject a new airflow into the inner tube device 6, which strengthens the airflow and makes it easier to blow away and carry away the accumulated slag.
[0046] The inner tube device 6 includes an inner tube 7 suspended in the long horizontal pipe 4, a row of U-shaped pads 8 set in the gap between the long horizontal pipe 4 and the inner tube 7 on one side, a long pad shaft 9 set in the gap between the long horizontal pipe 4 and the inner tube 7 on the other side, and a row of control components 10 sleeved on the inner tube 7. The conveying airflow carries the slag through the inner tube 7. If large or heavy particles are retained in the inner tube 7, they will obstruct the subsequent conveying of slag and gradually accumulate near the large or heavy slag particles. As the weight of the inner tube 7 increases, the inner tube 7 will shift in the long horizontal pipe 4, that is, the inner tube 7 will be closer to the long pad shaft 9. The displacement of the inner tube 7 is detected to analyze whether there is slag accumulation inside the inner tube 7.
[0047] The transfer box 5 includes a vertical box 11 fixedly connected between the L-shaped discharge pipe 3 and the long horizontal pipe 4, a U-shaped trough box 12 fixed in the vertical box 11, a strong air blower 13 set at one end of the U-shaped trough box 12, a connecting device 14 set at the end of the inner pipe 7, and a first adapter shaft 15, a second adapter shaft 16 and a motor shaft 17 installed at the bottom of the vertical box 11. One end of the motor shaft 17 passes through the housing of the vertical box 11 and extends to the outside, and is connected to the motor drive mechanism in the prior art. One end of the 7 is connected to the other end of the U-shaped trough box 12 by setting an opening cylinder.
[0048] refer to Figure 4 It is understood that the opening of the inner tube 7 and the round opening on the side of the U-shaped trough box 12 are connected. The round opening of the U-shaped trough box 12 leaves space for the opening of the inner tube 7 to move. The outer edge of the opening of the inner tube 7 slides in contact with the inner wall of the U-shaped trough box 12 through the setting of a ring plate. The opening at the top of the U-shaped trough box 12 is connected to the L-shaped discharge pipe 3. The upright box 11 serves to protect the internal parts. The U-shaped trough box 12 is actually used for material transportation. The airflow in the L-shaped discharge pipe 3 drives the slag into the U-shaped trough box 12, and then into the inner tube 7. The L-shaped discharge pipe 3, the U-shaped trough box 12 and the inner tube 7 form a closed channel to prevent the airflow from leaking out.
[0049] A cavity is left between the upright box 11 and the U-shaped trough box 12, and the first adapter shaft 15, the second adapter shaft 16, the motor shaft 17, the powerful fan 13, and the connecting device 14 are all distributed in the cavity. The upright box 11 is equipped with a bottom frame to limit and support the first adapter shaft 15, the second adapter shaft 16, and the motor shaft 17. One end of the motor shaft 17 extends out of the upright box 11. The first adapter shaft 15 and the second adapter shaft 16 both transmit power between the powerful fan 13 and the connecting device 14. (Reference) Figure 4 It is understood that two bottom brackets are fixed on the upright box 11, and the first adapter shaft 15, the second adapter shaft 16 and the motor shaft 17 are respectively movably sleeved in different through holes on the bottom brackets.
[0050] refer to Figure 6 The control assembly 10 includes a control ring cylinder 18 that is movably sleeved on the outside of the inner tube 7, two symmetrically distributed T-shaped rail posts 19 on one side of the control ring cylinder 18, and a C-shaped spring piece 20 with one end fixed on the control ring cylinder 18. The T-shaped rail posts 19 are fixed on the long horizontal tube 4, and the T-shaped rail posts 19 are slidably inserted into the T-shaped grooves opened on the control ring cylinder 18. The C-shaped spring piece 20 supports the control ring cylinder 18 to resist the downward pressure from the inner tube 7.
[0051] Two rows of symmetrical C-shaped spring clips 20 are installed below the inner tube 7. The C-shaped spring clips 20 are placed between the long horizontal tube 4 and the inner tube 7, applying an upward thrust to the inner tube 7. After the inner tube 7 rises, it is intercepted by the U-shaped pad 8, so that the inner tube 7 is suspended in the middle of the long horizontal tube 4. If there is no slag inside the inner tube 7, the weight of the inner tube 7 itself cannot press down the two rows of C-shaped spring clips 20. If there is accumulated slag inside the inner tube 7, the two rows of C-shaped spring clips 20 alone cannot support the inner tube 7, so the inner tube 7 shifts downward inside the long horizontal tube 4.
[0052] refer to Figure 6 Understandably, the long pad shaft 9 includes a speed-stabilizing shaft 22 supported by a protrusion on the inner wall of the long flat tube 4, and a row of semi-cylindrical plates 21 fixed on the speed-stabilizing shaft 22. Each semi-cylindrical plate 21 is distributed below the control ring cylinder 18. The semi-cylindrical plates 21 limit the displacement of the inner tube 7 by padding between the speed-stabilizing shaft 22 and the control ring cylinder 18.
[0053] With the spatial position of the long horizontal tube 4 unchanged, the inner tube 7 descends within the long horizontal tube 4. When the inner tube 7 and the long horizontal tube 4 are no longer coaxial, it can be defined as the inner tube 7 shifting. The speed-stabilizing shaft 22 is movably sleeved in the through hole opened on the boss. By rotating the speed-stabilizing shaft 22, the position of the half-cylinder plate 21 is changed. After the half-cylinder plate 21 is placed between the speed-stabilizing shaft 22 and the control ring cylinder 18, the control ring cylinder 18 cannot descend, that is, the inner tube 7 cannot descend. At the same time, the inner tube 7 is blocked above by the U-shaped pad 8. In this way, the position of the inner tube 7 remains stable and is suspended in the middle of the long horizontal tube 4. Once the rotating half-cylinder plate 21 leaves between the speed-stabilizing shaft 22 and the control ring cylinder 18, leaving offset space below the control ring cylinder 18, it will start to determine whether there is slag retention in the inner tube 7. If there is slag retention, the weight from the inner tube 7 is greater than the thrust of the two rows of C-shaped springs 20, and the inner tube 7 will shift and descend. Conversely, if there is no slag retention in the inner tube 7, that is, there is no channel blockage.
[0054] Two rows of C-shaped springs 20 stably support the control ring cylinder 18, preventing the inner tube 7 from shifting. The speed-stabilizing shaft 22 rotates continuously, while the semi-cylinder plate 21 intermittently supports the control ring cylinder 18. The two rows of C-shaped springs 20 will rest intermittently. Without the support of the semi-cylinder plate 21, the two rows of C-shaped springs 20 would be compressed for a long time, potentially leading to elastic fatigue. In this case, even if there is no slag residue in the inner tube 7, the weight of the inner tube 7 itself will compress the softened C-shaped springs 20, causing the inner tube 7 to shift downwards. Therefore, this invention uses the intermittent support of the semi-cylinder plate 21 to allow the C-shaped springs 20 time to rest and recover, ensuring that the C-shaped springs 20 have sufficient elasticity each time a weight test is performed, thus more accurately detecting whether there is slag residue in the inner tube 7.
[0055] refer to Figure 7The actuator 14 includes an output shaft 23 that drives between the speed-regulating shaft 22 and the motor shaft 17, an actuator assembly 24 that drives on one side of the output shaft 23, and a first slanted worm gear 25 that engages with an external gear ring fixed on the inner tube 7, as well as a rear frame 26 that simultaneously supports the output shaft 23, the actuator assembly 24 and the first slanted worm gear 25, and the rear frame 26 is fixed on the U-shaped slot box 12, and the first slanted worm gear 25 and the first adapter shaft 15 establish a transmission.
[0056] The actuator 24 includes a press frame 27 that slides through the inside of a plate cylinder on the rear frame 26, a spring clip 28 that applies elastic force to one end of the press frame 27, a double-control shaft gear 29 supported and driven on the press frame 27, a tail gear 30 distributed at one end of the double-control shaft gear 29, and a trigger shaft 31 coaxially and fixedly connected to the tail gear 30. One end of the press frame 27 contacts the outer wall of the inner tube 7 through an arc plate. The trigger shaft 31 and the second adapter shaft 16 drive perpendicularly. The lead-out shaft 23 meshes with the double-control shaft gear 29 through a fixed gear. The offset inner tube 7 causes the double-control shaft gear 29 to move axially by pressing the press frame 27. The axially moving double-control shaft gear 29 and the tail gear 30 establish a meshing transmission.
[0057] Detailed description of the functions of each component inside the docking actuator 14: The rear frame 26 remains stationary in space. Multiple through holes are provided on the rear frame 26 for movable connection, supporting the limiting lead-out shaft 23, the first worm gear 25, and the initiating shaft 31. An external motor drives the motor shaft 17 to rotate. The end of the motor shaft 17 is connected to a fixed bevel gear at the bottom of the lead-out shaft 23 via a fixed bevel gear for directional transmission. Two bevel gears are similarly installed between the lead-out shaft 23 and the stabilizing shaft 22. The rotating lead-out shaft 23 drives the stabilizing shaft 22. One end of the double-control shaft gear 29 has a shaft body, which is movably fitted into a through hole on the pressure frame 27. The lead-out shaft 23 drives the double-control shaft gear 29. At this time, the double-control shaft gear 29 rotates freely in place. If the inner tube 7 shifts, it presses downwards against the pressure frame 27. The downward movement of the pressure frame 27 will drive the double-control shaft gear 29. The axially moving double-control shaft gear... The gear 29 and the tail gear 30 mesh together. The rotating double-controlled shaft gear 29 will drive the initiating shaft 31. The initiating shaft 31 and the second transfer shaft 16 are connected by two bevel gears to achieve a change of direction. The rotating initiating shaft 31 will drive the second transfer shaft 16, and then the second transfer shaft 16 will drive the strong air blower 13. In summary, the connecting device 14 establishes a transmission between the motor shaft 17 and the speed stabilizing shaft 22. During the slag conveying process, the speed stabilizing shaft 22 needs to rotate slowly and continuously. On the other hand, the connecting device 14 has a detection mechanism inside. That is, the offset inner tube 7 will press the pressure frame 27, establish a transmission branch in the connecting device 14, and finally cause the initiating shaft 31 to rotate. Then, the strong air blower 13 is driven to work through the second transfer shaft 16. Thirdly, if the first inclined worm gear 25 rotates, it will drive the inner tube 7 to rotate, which will cause the slag accumulated in the inner tube 7 to roll.
[0058] The powerful fan 13 includes a charging section 32 located at a circular opening on one side of the housing of the upright box 11, a fan 33 driven by the charging section 32, a vertical shaft 34 that transmits power between the charging section 32 and the first adapter shaft 15, and a second oblique worm gear 35 that transmits power between the charging section 32 and the second adapter shaft 16. Multiple one-way springs 46 are evenly arranged around one side of the fan 33. Each one-way spring 46 corresponds to a plate hole opened on the housing of the U-shaped slot box 12, and the middle of the one-way spring 46 is fixed to the U-shaped slot box 12 by a spring. The fan 33 rotates to blow external airflow towards the U-shaped slot box 12, and the airflow is injected into the U-shaped slot box 12 by blowing up the one-way springs 46 inside the U-shaped slot box 12.
[0059] The charging unit 32 includes a horizontal frame 38 fixed to the vertical box 11, a fan shaft 39 with limiting support in the middle of the horizontal frame 38, a spring assembly 36 driven at one end of the fan shaft 39, a short control shaft 40 establishing transmission between the vertical shaft 34 and the fan shaft 39, and a multi-position frame 37 for supporting the spring assembly 36. The multi-position frame 37 is fixed to the horizontal frame 38, and the other end of the fan shaft 39 is fixed to the middle of the fan 33. The multi-position frame 37 simultaneously limits and supports the second worm gear 35 and the vertical shaft 34. The spring assembly 36 collects intermittent rotational power from the second worm gear 35, and drives the fan shaft 39 to rotate after the spring assembly 36 is fully charged.
[0060] Detailed description of the structure and function of the powerful fan 13: As previously mentioned, if the inner tube 7 shifts, it will cause the trigger shaft 31 to rotate, which in turn will drive the second worm gear 35 through the second adapter shaft 16. The end of the second worm gear 35 is connected to the bevel gear fixed at the end of the second adapter shaft 16 via a fixed bevel gear. The spring assembly 36 is a prior art structure, including a dual-purpose ring cylinder 44 surrounding the fan shaft 39, a spring 45 fixed to the outside of the dual-purpose ring cylinder 44, a cover cylinder 42 fixed to the outside of the spring 45, a T-disc gear 43 that establishes linkage between the fan shaft 39 and the cover cylinder 42, and a side spring 41 that intercepts and locks the fan shaft 39 outside the cover cylinder 42. The second worm gear 35 rotates... The dual-purpose ring cylinder 44 is fixed to the external ring gear. The rotation of the dual-purpose ring cylinder 44 causes the external spring 45 to contract and store power. The outer end of the spring 45 is fixed to the cover cylinder 42. An arc groove is opened on the outer wall of the cover cylinder 42, and the arc groove is engaged with the edge spring piece 41 fixed on the multi-position frame 37. In this way, the cover cylinder 42 cannot rotate. A back plate frame is fixed on one side of the cover cylinder 42, and the dual-purpose ring cylinder 44 is movably sleeved in the through hole opened in the middle of the back plate frame. At the same time, the dual-purpose ring cylinder 44 is also movably sleeved in the round hole opened on the multi-position frame 37. In this way, the multi-position frame 37 supports the dual-purpose ring cylinder 44, and the dual-purpose ring cylinder 44 and the cover cylinder 42 can rotate relative to each other. At the same time, the dual-purpose ring cylinder 44 also supports the cover cylinder 42. Continuing with the winding of the mainspring 45, the locked cover cylinder 42 does not rotate. When the mainspring 45 has accumulated sufficient pressure, it breaks the lock between the edge spring 41 and the cover cylinder 42, releasing the power and driving the cover cylinder 42 to rotate one revolution. One revolution of the cover cylinder 42 corresponds to the subsequent rapid rotation of the fan 33 multiple times. The pressure accumulation process of the mainspring 45 corresponds to the intermittent rotation of the second inclined worm gear 35, that is, the intermittent rotation of the second adapter shaft 16. If there is slag accumulation inside the inner tube 7, the inner tube 7 is not continuously... As the downward offset continues, the rotation of the long pad shaft 9 is continuous. The half-cylinder plate 21 will intermittently push the control ring cylinder 18 upward, causing the inner tube 7 to rise and reset. Therefore, the excessively heavy inner tube 7 is intermittently offset downward. Although the lead-out shaft 23 continues to rotate to drive the double-control shaft gear 29, the periodic rise and fall of the double-control shaft gear 29 will cause the trigger shaft 31 driven by the double-control shaft gear 29 to rotate intermittently. The trigger shaft 31 drives the second adapter shaft 16, and the second adapter shaft 16 and the subsequent second worm gear 35 will rotate intermittently.
[0061] The specific transmission between the cover cylinder 42 and the fan 33 is as follows: the cover cylinder 42 is driven by a fixed internal gear ring meshing with the T-disc gear 43. The middle part of the T-disc gear 43 is movably sleeved in the through hole opened on the multi-position frame 37 by a shaft. The end of the fan shaft 39 is driven by a fixed gear meshing with the T-disc gear 43. In this way, the cover cylinder 42 rotates once, driving the T-disc gear 43 to rotate, which in turn drives the fan shaft 39 to rotate multiple times. The fan shaft 39 drives the fan 33 to rotate, and the rotation of the fan 33 realizes air delivery, that is, generating a new strong airflow that is injected into the U-shaped slot box 12 and then into the inner tube 7. The enhanced airflow impact carries away the slag accumulated in the inner tube 7.
[0062] The fan shaft 39 is driven by a fixed outer ring gear that meshes with a gear fixed at one end of the short control shaft 40. The other end of the short control shaft 40 is driven by a fixed bevel gear that meshes with a bevel gear fixed at the top of the vertical shaft 34. The short control shaft 40 is movably sleeved in the through hole of the water pipe of the multi-position frame 37. The rotating fan shaft 39 will also drive the short control shaft 40, which will then drive the first adapter shaft 15 through the vertical shaft 34, causing the first worm gear 25 to rotate, which in turn drives the inner tube 7 to rotate. As mentioned before, the rotation of the inner tube 7 causes the internal slag to move, which enhances the airflow and makes it easier to blow away the slag.
