Description

Technical Field

[0001] This invention relates to a slag well material discharge and coke removal device, belonging to the technical field of boiler slag wells. Background Technology

[0002] In recent years, with the continuous development of thermal power enterprises and the constant changes in the coal supply market, the coal used in the operation of some power plants has deviated from the design coal type. Some coal types even contain high levels of elements such as silicon and sulfur. These elements gradually turn into a molten state in the high-temperature environment inside the boiler and gradually accumulate, eventually forming large chunks of coke that fall into the slag pit.

[0003] Most existing slag pits are protected with steel plates and refractory castables. However, as the operating time increases, some of the castable surface may fall off, making the slag pit surface rough and difficult to discharge. In addition, some slag pits have defects in the original design structure with a shallow slope, resulting in a large amount of coke slag accumulating at the slag pit outlet. This prevents the crushing device below the slag pit from effectively crushing the slag blocks and loses its slag discharge capacity. Manual coke cleaning or shutdown maintenance is inefficient and poses a risk of high-temperature operation, affecting the economic efficiency and safety of power plant operation.

[0004] A slag removal system for a three-waste boiler disclosed in Chinese utility model patent publication number CN209484634U includes a furnace, a slag pit, a first shut-off gate, a second shut-off gate, a hydraulic crusher, a steel belt slag conveyor, a first bearing, a second bearing, a sealing plate, a cold air blower, a hot air transmission pipeline, a bag filter, valves, a vertical shaft, a first slag crusher, a second slag crusher, and a slag bin. The first shut-off gate, the hydraulic crusher, and the steel belt slag conveyor are installed below the slag pit, and the first slag crusher, the second slag crusher, the second shut-off gate, and the slag bin are installed in the vertical shaft.

[0005] The slag well in the above-mentioned reference example does not have any slag buffer structure inside, which makes it easy for slag blocks to form at the slag well outlet and block the outlet. Therefore, it is urgent to improve it. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention designs a slag well unloading and coking device, which can effectively prevent slag wellhead blockage and avoid excessive wear on the inner wall of the slag well.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A slag well decoking device includes a buffer structure, which includes guide plates. Inside the well body, multiple guide plates are arranged in an inclined and staggered manner from top to bottom, with any two adjacent guide plates having opposite inclination directions. Outside the well body, a number of flipping devices corresponding to each guide plate are arranged in a sequential manner from top to bottom. The flipping devices are connected to the guide plates and are used to drive the guide plates to flip.

[0009] Furthermore, the tilting device includes a fixed plate fixedly connected to the outer wall of the well body. The top of the fixed plate is provided with a drive assembly, a reciprocating motion mechanism and a tilting assembly. The tilting assembly includes a second support rod. A tilting shaft is rotatably mounted on the top of the second support rod. One end of the tilting shaft rotatably passes through the well body and is fixedly connected to the side wall of the guide plate. The other end of the tilting shaft is fixedly sleeved with a meshing gear. The drive assembly drives the meshing gear to rotate reciprocally through the reciprocating motion mechanism.

[0010] Furthermore, the reciprocating motion mechanism includes a horizontally arranged slide rail, which is fixedly arranged on the outside of the second support rod. A rack and pinion slide rod is slidably installed on the outside of the slide rail. The top of the rack and pinion slide rod has a plurality of tooth blocks along its length direction that mesh with a meshing gear. A vertically arranged guide plate is fixedly connected to the outside of the rack and pinion slide rod. A guide groove is opened in the extension direction of the guide plate. A sliding hinge block is slidably installed in the guide groove. A swing plate is hinged to the outside of the sliding hinge block. A transmission shaft is fixedly sleeved on the free end of the swing plate. The drive assembly is used to drive the transmission shaft to rotate.

[0011] Furthermore, the drive assembly includes a support rod fixed to the top of the fixed plate, a mounting block fixedly disposed at the top of the support rod, a drive device mounted on the mounting block, and the drive device being connected to the drive shaft.

[0012] Furthermore, at least one hammering device is provided inside the guide plate. The hammering device includes a fixed base. One side of the fixed base is fixedly connected to the guide plate via a connecting leg. The other side of the fixed base is provided with a power storage component and a hammering component. The hammering component includes a hammering seat and a hammering head. The hammering seat is slidably mounted on the power storage component. The hammering head is fixedly mounted at the end of the hammering seat. The power storage component is used to drive the hammering head to hammer the end of the guide plate.

[0013] Furthermore, the power storage component includes a sliding seat and a pushing component. The sliding seat is slidably mounted on the top of the fixed seat, and the hammering seat is slidably mounted on the top of the sliding seat. A top block is fixedly connected to the top of the sliding seat, and a connecting sleeve rod is fixedly connected to the end of the hammering seat away from the hammering head. The connecting sleeve rod is slidably disposed through the top block, and a spring is movably sleeved on the connecting sleeve rod between the hammering seat and the top block. The pushing component is used to drive the sliding seat to move along the spring compression direction, and a limiting rod assembly for releasing the spring force is provided at the top of the hammering seat.

[0014] Furthermore, the limiting rod assembly includes a locking rod, which is movably disposed at the top of the hammer base, and the end of the locking rod away from the top block is hinged to the fixed base; the end of the locking rod near the top block is provided with a first inclined surface, the bottom end of the locking rod is provided with a locking block, and the side of the locking block away from the top block is provided with a second inclined surface; a limiting block fixed to the top of the hammer base is provided between the locking rod and the top block, and an inclined block is integrally fixedly connected between the side of the limiting block away from the top block and the top surface of the hammer base; the top of the limiting block is provided with a fourth inclined surface, and the top of the top block is provided with a third inclined surface.

[0015] Furthermore, the pushing assembly includes a driving component, a driving gear, and a second sliding seat. The driving component is fixedly installed inside the well body, the driving gear is connected to the driving component in a transmission manner, and the second sliding seat is fixed on one side of the sliding seat. The top of the second sliding seat has a plurality of meshing teeth along the length direction that mesh with the driving gear.

[0016] Furthermore, a heat-insulating interlayer is provided inside the guide plate.

[0017] Furthermore, there are two hammering devices, and the hammering directions of the two hammering devices are opposite.

[0018] Compared with the prior art, the present invention has the following features and beneficial effects:

[0019] 1. This invention alters the path of molten slag by alternating the flipping of guide plates, with adjacent guide plates tilting in opposite directions and flipping independently. This prevents slag from accumulating in a single location. After repeated impacts with the guide plates, the kinetic energy of the molten slag decreases, and large pieces of coke naturally break up, reducing the load on the crusher below and lowering the risk of outlet blockage. The flipping device adjusts the angle of the guide plates, compensating for the deficiency of the slope being too small in the original design, ensuring that the molten slag continues to slide down. Furthermore, for the adhesive molten slag produced by high-silicon and high-sulfur coal, dynamic flipping can forcibly peel off the coke lumps adhering to the surface of the guide plates. Even if the refractory castable in the well wall falls off, causing the inner wall to become rough, the active flipping of the guide plates can still ensure smooth slag flow.

[0020] 2. This invention targets the viscous slag of high-silicon and high-sulfur coal. Two hammering devices alternately hammer the slag at an upward / downward angle, covering both ends of the guide plate. This ensures that the slag is peeled off without any dead angles. At the same time, the flipping function of the guide plate can change its vertical position, which can further clean the slag. The flipping of the guide plate changes the slag accumulation position, and the hammering devices remove residual slag. This forms a closed-loop anti-clogging system of dynamic flow guidance and mechanical slag removal. The intermittent impact with spring energy storage is energy-saving and efficient.

[0032] The present invention will now be described in more detail with reference to the embodiments.

[0033] Example 1

[0034] Please see Figures 1 to 3The slag well descaling device of this embodiment includes a buffer structure, which includes a guide plate 2. Multiple inclined and staggered guide plates 2 are arranged sequentially from top to bottom inside the well body 1. The inclination directions of any two adjacent guide plates 2 are opposite. The molten slag entering from the upper end of the well body 1 will fall onto the guide plate 2 first. During the falling process, the molten slag will hit the guide plate 2 multiple times, and the kinetic energy of the molten slag will be gradually buffered, avoiding large pieces of molten slag from directly impacting the slag well outlet, significantly reducing the risk of outlet blockage. At the same time, the guide plate 2 disperses the molten slag to different heights and positions, preventing it from accumulating at the outlet and alleviating the slag accumulation problem caused by insufficient slope in the original design.

[0035] Several flipping devices 3, corresponding one-to-one with each guide plate 2, are arranged on the outside of the well body 1 from top to bottom. The flipping devices 3 are connected to the guide plates 2 and are used to drive the guide plates 2 to flip. The flipping devices 3 can periodically or in real time adjust the angle of the guide plates 2, forcibly change the direction of molten slag falling, and avoid molten slag from accumulating in the same position for a long time and forming a blockage.

[0036] Please see Figure 2 and Figure 3 The overturning device 3 includes a fixed plate 4 that is fixedly connected to the outer wall of the well body 1. The top of the fixed plate 4 is provided with a drive assembly, a reciprocating motion mechanism and an overturning assembly.

[0037] The flipping assembly includes a second support rod 14, with a second mounting block 15 fixedly connected to the top of the second support rod 14. The second mounting block 15 has a mounting hole, and a flipping shaft 16 is rotatably installed in the mounting hole. One end of the flipping shaft 16 rotates through the well body 1 and is fixedly connected to the side wall of the guide plate 2. The other end of the flipping shaft 16 is fixedly sleeved with a meshing gear 17. The drive assembly drives the meshing gear 17 to rotate back and forth through a reciprocating motion mechanism.

[0038] Specifically, the reciprocating motion mechanism includes a horizontally arranged slide rail 13, which is fixedly arranged on the outside of the support rod 14. A slide groove 1301 is provided on the outside of the slide rail 13. A rack and pinion slide rod 12 is slidably installed on the outside of the slide rail 13. The side of the rack and pinion slide rod 12 is slidably engaged with the slide groove 1301. Several tooth blocks that mesh with the meshing gear 17 are provided at the top of the rack and pinion slide rod 12 along its length direction. A vertically arranged guide plate 11 is fixedly connected to the outside of the rack and pinion slide rod 12. A guide groove 1101 is opened in the extension direction of the guide plate 11. A sliding hinge block 10 is slidably installed in the guide groove 1101. A swing plate 9 is hinged to the outside of the sliding hinge block 10. A transmission shaft 8 is fixedly sleeved at the free end of the swing plate 9. The drive assembly is used to drive the transmission shaft 8 to rotate.

[0039] The drive assembly includes a support rod 5 fixed to the top of the fixed plate 4, a mounting block 6 fixedly installed at the top of the support rod 5, a drive device 7 installed on the mounting block 6, and the drive device 7 being connected to the drive shaft 8.

[0040] In this embodiment, the drive device 7 is a motor and is electrically connected to the PLC controller.

[0041] As described above, starting the drive device 7 can drive the transmission shaft 8 to rotate, which in turn drives the swing plate 9 to rotate. During rotation, the free end of the swing plate 9 can drive the sliding hinge block 10 to perform circular motion. Since the sliding hinge block 10 is slidably engaged in the guide groove 1101, it can move up and down within the guide groove 1101. Therefore, the guide plate 11 can be driven to move laterally during the movement of the sliding hinge block 10. The lateral movement of the guide plate 11 can also drive the rack and pinion 12 to slide along the slide groove 1301. During the sliding of the rack and pinion 12, the toothed block at the top of the rack and pinion 12 can drive the meshing gear 17 to rotate. The rotation of the meshing gear 17 can simultaneously drive the rotating shaft 16 to rotate. The rack and pinion 12 reciprocates along the slide groove 1301, thereby causing the guide plate 2 to rotate.

[0042] By alternating the flipping of the guide plates 2, with adjacent guide plates 2 tilting in opposite directions and flipping independently, the falling path of the molten slag is forcibly changed, avoiding accumulation in a single position. After the molten slag impacts the guide plates 2 multiple times, its kinetic energy is attenuated, and large pieces of coke slag naturally break up, reducing the load on the crusher below and lowering the risk of outlet blockage. The angle of the guide plates 2 is adjusted by the flipping device 3, which compensates for the defect of the slope being too small in the original design, ensuring that the molten slag continues to slide down. In addition, for the adhesive molten slag produced by high-silicon and high-sulfur coal, dynamic flipping can forcibly peel off the coke lumps adhering to the surface of the guide plates 2. Even if the refractory castable of the well wall falls off, causing the inner wall to become rough, the active flipping of the guide plates 2 can still ensure smooth flow of molten slag.

[0043] Example 2

[0044] Please see Figures 4 to 7 In this embodiment of the slag well decoking device, based on the above embodiment one, two hammering devices 18 are provided in the guide plate 2. The hammering directions of the two hammering devices 18 are opposite, so that the hammering devices 18 can hammer and vibrate the guide plate 2 in both directions at all times, and avoid the molten slag in the molten state from adhering to the guide plate 2.

[0045] In this embodiment, one of the hammering devices 18 is tilted downwards in the hammering direction, and the other hammering device 18 is tilted upwards in the hammering direction.

[0046] Specifically, the hammering device 18 includes a fixed base 19, one side of which is fixedly connected to the guide plate 2 via a connecting leg 1901.

[0047] The other side of the fixed base 19 is provided with a power storage component and a hammering component.

[0048] The hammering assembly includes a hammering seat 30 and a hammering head 31. The hammering seat 30 is slidably mounted on the power storage assembly, and the hammering head 31 is fixedly mounted at the end of the hammering seat 30. The power storage assembly is used to drive the hammering head 31 to hammer the end of the guide plate 2.

[0049] Please see Figure 5 , Figure 6 and Figure 7 The power storage component includes a sliding seat 20 and a pushing component. The sliding seat 20 is slidably mounted on the top of the fixed seat 19, and the hammering seat 30 is slidably mounted on the top of the sliding seat 20. In this embodiment, the top of the sliding seat 20 is provided with a trapezoidal sliding groove, and the hammering seat 30 is slidably mounted in the sliding groove.

[0050] A top block 26 is fixedly connected to the top of the sliding seat 20. A connecting sleeve rod 27 is fixedly connected to the end of the hammer seat 30 away from the hammer head 31. The connecting sleeve rod 27 slides through the top block 26. After the connecting sleeve rod 27 slides through the top block 26, a limit sleeve 32 is fixedly fitted to prevent the connecting sleeve rod 27 from separating from the top block 26. A spring 28 is provided between the hammer seat 30 and the top block 26 and is movably fitted outside the connecting sleeve rod 27.

[0051] The pushing component is used to drive the sliding seat 20 to move along the compression direction of the spring 28, and the top of the hammer seat 30 is provided with a limiting rod assembly for releasing the elastic force of the spring 28.

[0052] Specifically, the limiting rod assembly includes a locking rod 25, which is movably disposed at the top of the hammer seat 30, and the end of the locking rod 25 away from the top block 26 is hinged to the fixed seat 19. In this embodiment, a hinge rod 23 is fixedly connected to the side of the fixed seat 19, and a rotating shaft 24 is vertically rotatably connected to the top of the hinge rod 23. The end of the locking rod 25 near the hammer head 31 is fixedly sleeved with the free end of the rotating shaft 24.

[0053] The end of the lever 25 near the top block 26 is provided with a first inclined surface 2501, the bottom end of the lever 25 is provided with a locking block 2502, and the side of the locking block 2502 away from the top block 26 is provided with a second inclined surface 2503.

[0054] A limiting block 29 is fixed to the top of the hammer base 30 between the locking rod 25 and the top block 26. An inclined block 2902 is integrally fixedly connected between the side of the limiting block 29 away from the top block 26 and the top surface of the hammer base 30. An inclined surface 2901 is provided at the top of the limiting block 29, and an inclined surface 2601 is provided at the top of the top block 26.

[0055] Furthermore, the driving component includes a driving member, a driving gear 22, and a sliding seat 21. The driving member is fixedly installed inside the well body 1, the driving gear 22 is connected to the driving member for transmission, and the sliding seat 21 is fixed on the side of the sliding seat 20. The top of the sliding seat 21 is provided with a number of meshing teeth along the length direction that mesh with the driving gear 22.

[0056] In this embodiment, the driving component is a motor, which is wirelessly connected to the PLC controller of the peripheral device.

[0057] As can be seen from the above description, please refer to Figure 6 and Figure 7 At this time, the hammer seat 30 is in the released state. When it is necessary to hammer the guide plate 2, the drive gear 22 is driven to rotate by controlling the drive component. The rotation of the drive gear 22 can drive the sliding seat 20 to move to the right through the meshing teeth. The movement of the sliding seat 20 to the right can drive the top block 26 to move to the right as well. The movement of the top block 26 to the right can push the hammer seat 30 to the right through the connecting sleeve rod 27.

[0058] As the hammer base 30 moves to the right, the limiting block 29 also moves to the right. During this process, the limiting block 29 first contacts the locking rod 25 and uses the inclined surface 2501 at the end of the locking rod 25 to lift the locking rod 25 to a certain height, preventing the locking rod 25 from being stuck. Then, the limiting block 29 continues to move to the right, and the inclined block 2902 will contact the locking block 2502. The slope of the inclined block 2902 can push the locking block 2502 upward, thereby lifting the locking rod 25 to a certain height. At this time, the inclined surface 2501 and the inclined surface 2601 at the top of the top block 26 are flush.

[0059] As the hammering seat 30 continues to move to the right, the locking block 2502 engages with the limiting block 29, and the spring 28 is compressed and begins to accumulate elastic force until the inclined surface 2501 at the end of the locking rod 25 and the inclined surface 2601 at the top of the top block 26 cooperate. During the movement of the top block 26 to the right, the locking rod 25 is directly lifted up. At this time, the locking block 2502 and the limiting block 29 are misaligned, and the elastic force of the spring 28 is released, which can then push the hammering seat 30 to the right so that the hammering head 31 can hammer the inner wall of the guide plate 2.

[0060] After the hammering is completed, a driving component drives the driving gear 22 to rotate in the opposite direction, which in turn drives the sliding seat 20 to return to its original position. At the same time as the sliding seat 20 returns to its original position, it also drives the hammering seat 30 to return to its original position through the connecting sleeve rod 27.

[0061] During the return of sliding seat 20, the inclined surface 2503 on the locking block 2502 cooperates with the inclined surface 2901 at the top of the limiting block 29 to lift the locking rod 25 and assist the hammer seat 30 in returning to its original position.

[0062] Furthermore, a heat insulation layer is provided inside the deflector plate 2, which can prevent the internal temperature of the deflector plate 2 from becoming too high.

[0063] For viscous slag from high-silicon and high-sulfur coal, two hammering devices 18 alternately hammer in an upward / downward direction, covering the upper and lower ends of the guide plate 2, ensuring that the slag is peeled off without dead angles. At the same time, the flipping function of the guide plate 2 can change the vertical position of the guide plate 2, thereby further cleaning the slag. The flipping of the guide plate 2 changes the slag accumulation position, and the hammering devices 18 remove residual slag, forming a closed-loop anti-clogging system of dynamic flow guidance and mechanical slag removal. The spring 28 stores energy and impacts intermittently, which is energy-saving and efficient.

[0064] The working principle of this invention is as follows: By alternately flipping the guide plates 2, adjacent guide plates 2 have opposite tilt directions and can be flipped independently, forcibly changing the falling path of the molten slag, avoiding accumulation in a single position. After the molten slag hits the guide plates 2 multiple times, the kinetic energy is reduced, and large pieces of coke slag naturally break up, reducing the load on the crusher below and reducing the risk of outlet blockage. The angle of the guide plates 2 is adjusted by the flipping device 3 to make up for the defect of the slope being too small in the original design, ensuring that the molten slag continues to slide down. In addition, for the adhesive molten slag produced by high-silicon and high-sulfur coal, dynamic flipping can forcibly peel off the coke lumps adhering to the surface of the guide plates 2. Even if the refractory castable of the well wall falls off and the inner wall becomes rough, the active flipping of the guide plates 2 can still ensure that the molten slag flows smoothly.
