Description

Technical Field

[0001] This invention relates to the field of coal feeding equipment technology for coal-fired power plants, specifically to a compartmentalized raw coal silo with bidirectional switching and anti-blocking structure. Background Technology

[0002] In large thermal power plants, to meet the continuous coal supply demands under heavy loads, a compartmentalized raw coal bunker structure is commonly used. This type of equipment divides the coal storage space into multiple independent silos, offering advantages such as large coal storage capacity, stable coal supply, and the ability to perform zonal maintenance. It is a core piece of equipment in the boiler fuel conveying system. However, during storage and transportation, raw coal is highly susceptible to adhesion, arching, and clumping at the lower coal hopper of the compartmentalized raw coal bunker due to factors such as its high moisture content, large particle size differences, and the co-firing of municipal sludge. This can lead to material discharge blockages.

[0003] Patent CN113154434B discloses a coal feeding device, which mainly consists of a coal bunker, a coal hopper, a coal chute, a sealing structure, a support assembly, a drive assembly, and a scraper assembly. The coal bunker and coal chute are fixedly installed, while the coal hopper can rotate relative to them around its own axis. The lower part of the coal bunker extends into the coal hopper. A sealing structure and support assembly are installed between the coal bunker and the coal hopper. A drive assembly is installed between the coal chute and the coal hopper to drive the coal hopper to rotate. A scraper assembly is installed inside the coal hopper. The scrapers are fixedly connected to the inner wall of the coal hopper and extend spirally along the axial direction. When the drive assembly drives the coal hopper to rotate forward and backward, the coal hopper synchronously drives all the scrapers inside to rotate together. The scrapers, with their fixed shape and angle, scrape and break up the coal, thereby preventing and clearing blockages and ensuring the smooth flow of raw coal.

[0004] Although the above solution improves the coal hopper blockage problem to some extent by using a rotating coal hopper with a fixed scraper, it still has obvious defects. The scraper in the above solution is a fixed structure, and the blade will continuously keep in contact with the falling coal. Even during the normal coal conveying stage of the equipment, the blade will continue to cut and scrape the normally flowing raw coal, which will accelerate the wear of the scraper itself. Summary of the Invention

[0005] To address the aforementioned issues, a compartmentalized raw coal bin with a bidirectional switching and anti-blocking structure is provided. The bidirectional switching and anti-blocking structure adjusts the cutter tilt angle, which, in conjunction with the forward and reverse rotation of the coal hopper, enables the switching of the cutter's working posture and the equipment's operating mode, thus adapting to the usage requirements under different working conditions.

[0006] To address the problems of existing technologies, this invention provides a compartmentalized raw coal bunker with a bidirectional switching and anti-blocking structure, comprising a bunker body, a coal hopper, a bidirectional switching anti-blocking structure, a synchronous switching structure, a fixing mechanism, and a rotating mechanism. The coal hopper is located at the bottom of the bunker body, and multiple cutters are arranged at equal intervals inside the coal hopper. Each cutter includes a cutting edge and a root extending spirally along the inner wall of the coal hopper. The bidirectional switching anti-blocking structure includes multiple rotating shafts, each corresponding to one of the cutters. The rotating shafts are perpendicular to the inner wall of the coal hopper and rotatably connected to the coal hopper. Each rotating shaft is connected to the middle of the root of the cutter, and the rotating shaft adjusts the tilt angle of the cutter's cutting edge by rotating. There are two synchronous switching structures, each connected to the upper and lower ends of the multiple cutters, and the synchronous switching structures are used to synchronously switch the working angle of all cutters. The fixing mechanism fixes the angle of the multiple cutters by fixing the synchronous switching structures. The rotating mechanism drives the coal hopper to rotate clockwise or counterclockwise.

[0007] Preferably, the synchronous switching structure includes an annular synchronous plate and multiple connecting components; the annular synchronous plate is coaxially disposed inside the coal hopper; the multiple connecting components are disposed on the annular synchronous plate, and the multiple connecting components are respectively connected to the multiple cutting tools one by one.

[0008] Preferably, the connecting assembly includes a connecting rod, a connecting block, and a universal connector; the connecting rod is connected to the annular synchronous plate, and the axis of the connecting rod is perpendicular to the inner wall surface of the coal hopper; the connecting block is slidably connected to the root of the cutter; the universal connector is used to connect the connecting rod and the connecting block.

[0009] Preferably, the connecting block is provided with a slider that is slidably connected to the root of the tool, and the root of the tool is provided with a groove to accommodate the slider.

[0010] Preferably, the coal hopper has multiple short slots, and the connecting assembly passes through the short slots and docks with the fixing mechanism.

[0011] Preferably, two annular grooves are formed on the inner wall of the coal hopper, and the annular synchronous plate is rotatably disposed in the annular grooves.

[0012] Preferably, the fixing mechanism includes two fixing rings and a fixing drive structure; each of the two fixing rings has a slot; the fixing drive structure is used to drive the slots on the fixing rings to dock with the synchronous switching structure.

[0013] Preferably, the fixed drive structure includes multiple guide columns and a lifting driver; the multiple guide columns are arranged at equal angles around the axis of the coal hopper, and each guide column is slidably provided with a sliding sleeve, which is connected to two fixed rings; the lifting driver is used to drive the sliding sleeve to slide along the guide column.

[0014] Preferably, the bidirectional switching anti-blocking structure further includes a synchronization component, which is used to drive all the rotating shafts to rotate synchronously.

[0015] Preferably, the bidirectional switching anti-blocking structure further includes a drive component, which is used to drive the synchronization component to rotate.

[0016] The advantages of this invention compared to the prior art are: 1. This invention comprises a coal bunker body, a coal hopper, a bidirectional switching anti-blocking structure, a synchronous switching structure, a fixing mechanism, and a rotating mechanism. During normal coal conveying, the rotating mechanism drives the coal hopper to rotate clockwise, while the fixing mechanism locks the synchronous switching structure, keeping the cutters in a fixed posture to guide the raw coal conveying. When coal blockage or coal caking occurs, the fixing mechanism releases its limit, and the bidirectional switching anti-blocking structure, in conjunction with the synchronous switching structure, drives all cutters to synchronously adjust their blade angles. After the angle adjustment is completed, the mechanism relocks, and the rotating mechanism drives the coal hopper to rotate in the opposite direction, allowing the cutters to break up and clear the coal. By adjusting the cutter angle using the bidirectional switching anti-blocking structure, and coordinating with the forward and reverse rotation of the coal hopper, the working posture of the cutters and the operating mode of the equipment can be switched, adapting to the usage requirements under different working conditions.

[0017] 2. This invention features an annular synchronous plate and multiple connecting components. During normal coal conveying, the cutters maintain a fixed posture to guide the raw coal downwards. When it is necessary to adjust the cutter tilt angle to clear blockages, the rotating shaft drives the cutter root to rotate. The cutters are linked to two sets of synchronous switching structures, and the connecting components transmit power to the annular synchronous plate. The annular synchronous plate then drives all connecting components to deflect synchronously with the cutters. During the adjustment process, the distance between adjacent cutters remains unchanged, and their relative positions do not shift, thus ensuring that all cutters complete the angle adjustment synchronously. No single set of cutters will deflect independently, effectively ensuring the consistency of the actions of all cutters.

[0018] 3. This invention features a connecting rod, a connecting block, and a universal connector. When adjusting the tool tilt angle, the rotating shaft drives the tool to rotate. During the tool's rotation, the connecting block revolves with the annular synchronous plate and slides along the root of the tool. The universal connector can compensate for positional deviations, maintaining the connection between the connecting rod and the connecting block at all times, ensuring normal power transmission. The sliding connection between the connecting block and the tool simplifies the movement process of the synchronous switching structure, thereby improving the smoothness of the tool angle adjustment process.

Rotating mechanism Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 10 As shown: A compartmentalized raw coal bunker with bidirectional switching and anti-blocking structure includes a bunker body 1, a coal hopper 2, a bidirectional switching anti-blocking structure 4, a synchronous switching structure 5, a fixing mechanism 6, and a rotating mechanism 7. The coal hopper 2 is located at the bottom of the bunker body 1, and multiple blades 3 are arranged at equal intervals inside the coal hopper 2. Each blade 3 includes a cutting edge and a root extending spirally along the inner wall of the coal hopper 2. The bidirectional switching anti-blocking structure 4 includes multiple rotating shafts 41, each corresponding to one of the multiple blades 3, and the rotating shafts 41 are perpendicular to the coal hopper 2. The inner wall surface is rotatably connected to the coal hopper 2. The rotating shaft 41 is connected to the middle part of the root of the cutter 3. The rotating shaft 41 adjusts the tilt angle of the cutting edge of the cutter 3 by rotating itself. There are two synchronous switching structures 5. The two synchronous switching structures 5 are respectively connected to the upper and lower ends of multiple cutters 3. The synchronous switching structures 5 are used to link all cutters 3 to switch working angles synchronously. The fixing mechanism 6 fixes the angle of multiple cutters 3 by fixing the synchronous switching structures 5. The rotating mechanism 7 is used to drive the coal hopper 2 to rotate clockwise or counterclockwise.

[0032] The rotating mechanism 7 uses a gear and ring transmission structure to drive the coal hopper 2 to rotate.

[0033] Under normal coal conveying conditions, the rotating mechanism 7 drives the coal hopper 2 to rotate clockwise, and the fixing mechanism 6 locks the synchronous switching structure 5, keeping each cutter 3 in a fixed posture. The cutting edges of the cutters 3 are arranged in a spiral direction, guiding the raw coal downwards by the side of the cutting edges. When coal blockage or coal lumps caking occur in the coal hopper 2, the fixing mechanism 6 releases the restriction on the synchronous switching structure 5, and all rotating shafts 41 rotate synchronously. Under the linkage of the synchronous switching structure 5, all cutters 3 rotate synchronously, uniformly adjusting the inclination angle of the cutting edges to form an inclination angle that can cut and break the coal lumps. After the angle of the cutter 3 is adjusted to the correct position, the fixing mechanism 6 relocks the synchronous switching structure 5 to fix the posture of the cutter 3; the rotating mechanism 7 drives the coal hopper 2 to rotate in the opposite direction, and the cutters 3 rotate with the coal hopper 2 to cut and break the lumped and arched coal, completing the unblocking of the coal blockage. After the blockage is cleared, the rotating shaft 41 drives the cutter 3 to rotate back to the initial posture, the fixing mechanism 6 locks again, the coal hopper 2 switches to forward operation, and the equipment resumes normal coal conveying. In this application, the device relies on the bidirectional switching anti-blocking structure 4 to adjust the tilt angle of the cutter 3, and in conjunction with the forward and reverse rotation of the coal hopper 2, it realizes the switching of the working posture of the cutter 3 and the operating mode of the equipment, which can adapt to the usage requirements under different working conditions.

[0034] Reference Figure 3 and Figure 4 As shown: The synchronous switching structure 5 includes an annular synchronous plate 51 and multiple connecting components 52; the annular synchronous plate 51 is coaxially arranged inside the coal hopper 2; the multiple connecting components 52 are arranged on the annular synchronous plate 51, and the multiple connecting components 52 are respectively connected to the multiple cutting tools 3 one by one.

[0035] During normal coal conveying, the cutter 3 maintains a fixed posture to guide the raw coal downwards. When it is necessary to adjust the inclination angle of the cutter 3 for unblocking operations, the rotating shaft 41 starts to rotate, driving the root of the cutter 3 to rotate. The upper and lower ends of the root of the cutter 3 respectively drive the operation of two sets of synchronous switching structures 5. The connecting component 52 in the synchronous switching structure 5 receives the rotational force transmitted by the cutter 3 and then transmits the force to the coaxially arranged annular synchronous plate 51, driving the annular synchronous plate 51 to rotate as a whole. When the annular synchronous plate 51 rotates, it drives all the connecting components 52 on it to move synchronously, ultimately allowing the entire set of cutters 3 to complete the angle deflection synchronously. During the entire rotation process of the cutter 3, the distance between the upper and lower ends of adjacent cutters 3 remains constant, and the relative positions of each cutter 3 will not shift. The synchronous switching structure 5 relies on the annular synchronous plate 51 and the connecting component 52 to achieve power linkage, thereby ensuring that all cutters 3 complete the angle adjustment synchronously, and no single set of cutters 3 will deflect individually, effectively ensuring the consistency of the movement of all cutters 3.

[0036] Reference Figure 4 and Figure 5As shown: The connecting assembly 52 includes a connecting rod 521, a connecting block 522, and a universal connector 523; the connecting rod 521 is connected to the annular synchronous plate 51, and the axis of the connecting rod 521 is perpendicular to the inner wall surface of the coal hopper 2; the connecting block 522 is slidably connected to the root of the cutter 3; the universal connector 523 is used to connect the connecting rod 521 and the connecting block 522.

[0037] When adjusting the tilt angle of the cutter 3, the rotating shaft 41 drives the cutter 3 to rotate around its own axis. If the connecting component 52 is fixedly connected to the root of the cutter 3, during the operation of the cutter 3, the connecting component will simultaneously revolve with the coal hopper 2 and revolve with the cutter 3 around the rotating shaft 41, resulting in a complex overall motion and a tendency to jam. Therefore, the connecting block 522 and the root of the cutter 3 are set to a sliding fit, and the connecting rod 521 is connected to the connecting block 522 through the universal connector 523. The connecting rod 521 is perpendicular to the inner wall of the coal hopper 2 and fixed on the annular synchronous plate 51. When the cutter 3 rotates at an angle, it will drive the connecting block 522 and the connecting rod 521 to rotate together with the annular synchronous plate 51 around the axis of the coal hopper 2. At the same time, the connecting block 522 will slide relative to the root of the cutter 3 to adapt to the rotational motion of the cutter 3. The universal connector 523 can compensate for the positional deviation between the connecting block 522 and the connecting rod 521, maintaining the connection between the connecting rod 521 and the connecting block 522 throughout the sliding and rotation process, ensuring normal power transmission. The sliding connection between the connecting block 522 and the tool 3 simplifies the movement process of the synchronous switching structure 5, thereby improving the smoothness of the tool 3 angle adjustment process.

[0038] Reference Figure 5 As shown: The connecting block 522 is provided with a slider 5221 that is slidably connected to the root of the cutter 3, and the root of the cutter 3 is provided with a groove 31 for accommodating the slider 5221.

[0039] A groove 31 is formed at the root of the cutter 3, and a slider 5221 is mounted on the connecting block 522. The slider 5221 is embedded inside the groove 31, thereby achieving a sliding fit between the connecting block 522 and the root of the cutter 3. During the adjustment of the inclination angle of the cutter 3, the slider 5221 can move along the groove 31 to meet the position change requirements of the cutter 3 during rotation, and complete the angle adjustment in conjunction with the overall linkage structure. When the equipment is in normal coal conveying or unblocking operation, the raw coal will exert a force on the cutter 3 towards the inside of the coal hopper 2. At this time, the slider 5221 embedded in the groove 31 abuts against the wall of the groove 31, forming a locking fit. The slider 5221 can apply a reverse force to the cutter 3 to counteract the thrust brought by the raw coal, limit the cutter 3 from unexpected movements, and keep the cutter 3 in its current set posture. By sliding and engaging the slider 5221 with the groove 31, the relative sliding ability between the connecting block 522 and the tool 3 is preserved, and the tool 3 is limited during operation. This achieves stable locking of the tool 3's working posture while meeting the sliding adjustment requirements.

[0040] Reference Figure 6 As shown: Multiple short grooves 21 are opened on the coal hopper 2, and the connecting component 52 passes through the short grooves 21 and docks with the fixing mechanism 6.

[0041] Multiple short grooves 21 are formed on the side wall of the coal hopper 2. One end of the connecting rod 521 protrudes from the short groove 21 outside the coal hopper 2, and the protruding part can be connected to the fixing mechanism 6 on the outside. When it is necessary to lock the posture of the cutter 3, the fixing mechanism 6 limits and fixes the connecting rod 521 that protrudes from the short groove 21. After the connecting rod 521 remains stationary, the connecting block 522 and the cutter 3 connected to it are also fixed, maintaining the current working angle. During the adjustment of the angle of the cutter 3, the cutter 3 drives the connecting rod 521 to move together, and the connecting rod 521 will be displaced along the trajectory of the short groove 21. The groove wall of the short groove 21 will block the connecting rod 521, restricting its vertical range of movement, so that the connecting rod 521 can only move within the same horizontal plane and will not shift its position. Through the guiding and limiting effect of the short groove 21 on the connecting rod 521, the movement trajectory of the connecting rod 521 and the connecting block 522 is constrained, thereby realizing the sliding of the connecting block 522 within a fixed range on the cutter 3.

[0042] Reference Figure 6 As shown: Two annular grooves 22 are opened on the inner wall surface of the coal hopper 2, and the annular synchronous plate 51 is rotatably disposed in the annular grooves 22.

[0043] During the angle adjustment process of the cutter 3, the cutter 3 transmits power through the connecting rod 521, driving the annular synchronous plate 51 to rotate as a whole. The annular groove 22 provides a vertical limit for the annular synchronous plate 51, ensuring that it rotates within a predetermined height range without vertical deviation. Simultaneously, the annular synchronous plate 51 is arranged on the inner wall of the coal hopper 2, and its entire surface can block the short grooves 21 opened on the side wall of the coal hopper 2. When raw coal flows inside the coal hopper 2, it cannot overflow from the gaps in the short grooves 21. The annular groove 22 not only limits the movement position of the annular synchronous plate 51 and provides a running track for its rotation, but also, combined with the blocking effect of the annular synchronous plate 51, effectively prevents raw coal from leaking out of the groove opening while ensuring the smooth operation of the annular synchronous plate 51.

[0044] Reference Figure 2 and Figure 7 As shown: The fixing mechanism 6 includes two fixing rings 61 and a fixing drive structure 62; each of the two fixing rings 61 has a slot 611; the fixing drive structure 62 is used to drive the slot 611 on the fixing rings 61 to dock with the synchronous switching structure 5.

[0045] When the equipment is normally conveying coal and clearing blockages, the connecting rod 521 is engaged in the slot 611 of the fixing ring 61. The slot 611 constrains the connecting rod 521, preventing it from rotating around the axis of the coal hopper 2, thus keeping the cutter 3 fixed at its current angle. When it is necessary to adjust the angle of the cutter 3, the fixed drive structure 62 drives the two fixing rings 61 to move downwards as a whole. The slot 611 disengages from the connecting rod 521, and all the limits at both ends of the cutter 3 are released. The connecting rod 521 can then rotate with the annular synchronous plate 51 to complete the angle adjustment of the cutter 3. After the angle of the cutter 3 is adjusted to the correct position, the fixed drive structure 62 drives the two fixing rings 61 to return to their original position. The other slot 611 on the fixing ring 61 engages with the connecting rod 521, re-limiting the rotation of the connecting rod 521 and allowing the cutter 3 to maintain its new working posture. By driving the fixing rings 61 to rise and fall through the fixed drive structure 62, the limiting and unlocking of all connecting rods 521 are achieved, thus realizing the synchronous locking and unlocking of all cutter 3 states.

[0046] Reference Figure 7 and Figure 8 As shown: The fixed drive structure 62 includes a plurality of guide posts 621 and a lifting driver 623; the plurality of guide posts 621 are arranged at equal angles around the axis of the coal hopper 2, and the guide posts 621 are slidably provided with sliding sleeves 622, the sliding sleeves 622 being connected to two fixed rings 61; the lifting driver 623 is used to drive the sliding sleeves 622 to slide along the guide posts 621.

[0047] When the device needs to switch the state of tool 3, the lifting driver 623 outputs power to push the sliding sleeve 622 to slide linearly along the guide post 621. During the movement of the sliding sleeve 622, it will simultaneously drive the two fixed rings 61 to rise and fall together, thereby completing the docking or disengagement action of the slot 611 and the connecting rod 521. When the fixed ring 61 moves upward, the slot 611 engages with the connecting rod 521, and the upper and lower ends of the tool 3 are locked simultaneously; when the fixed ring 61 moves downward, the slot 611 disengages from the connecting rod 521, and the upper and lower ends of the tool 3 are released simultaneously. The guiding effect of the guide post 621 on the sliding sleeve 622 ensures that the sliding sleeve 622 and the fixed ring 61 always move along the predetermined trajectory, thereby ensuring that the fixed ring 61 will not rotate, so that after the tool 3 is adjusted, the slot 611 on the fixed ring 61 can accurately engage with the connecting rod 521.

[0048] Reference Figure 3 , Figure 9 and Figure 10 As shown: The bidirectional switching anti-blocking structure 4 also includes a synchronization component 42, which is used to drive all the rotating shafts 41 to rotate synchronously.

[0049] The synchronization component 42 includes a synchronization ring 421 and multiple synchronization drive wheels 422. The synchronization ring 421 is coaxially rotatably connected to the coal hopper 2, and the multiple synchronization drive wheels 422 are respectively connected to multiple rotating shafts 41, and the synchronization drive wheels 422 and the synchronization ring 421 mesh with each other.

[0050] When the equipment needs to adjust the angle of the cutter 3, the synchronizing ring 421 starts to rotate around the axis of the coal hopper 2. Relying on the meshing relationship of the gear teeth, the synchronizing ring 421 will simultaneously drive all the synchronizing transmission wheels 422 to rotate together. Each synchronizing transmission wheel 422 drives the corresponding rotating shaft 41 to rotate, and the rotating shaft 41 then drives the connected cutter 3 to complete the angle deflection, thereby realizing that all cutters 3 synchronously complete the attitude adjustment.

[0051] Reference Figure 9 and Figure 10 As shown: The bidirectional switching anti-blocking structure 4 also includes a drive component 43, which is used to drive the synchronization component 42 to rotate.

[0052] Specifically, the drive assembly 43 includes an internal gear ring 431, a transmission gear 432, and a rotary driver 433. The internal gear ring 431 is coaxially and fixedly connected to the synchronizing ring 421. The transmission gear 432 meshes with the internal gear ring 431. The rotary driver 433 is used to drive the transmission gear 432 to rotate.

[0053] When the fixing mechanism 6 releases the lock on the tool 3, the rotary driver 433 starts working, driving the transmission gear 432 to rotate. The rotating transmission gear 432, through meshing, drives the internal gear ring 431 to rotate synchronously. The synchronizing ring 421, connected to the internal gear ring 431, also rotates, thus providing power for subsequent tool 3 angle adjustment. Through the meshing of the internal gear ring 431 and the transmission gear 432, the rotation is transmitted in a stable ratio, allowing control of the rotation amplitude of the synchronizing ring 421, and consequently, the adjustment angle of the tool 3.

[0054] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
