Description

Technical Field

[0001] This utility model relates to the field of raw coal processing technology, specifically to an anti-blocking rapping device for raw coal bunkers. Background Technology

[0002] A raw coal silo is a storage silo for granular materials such as raw coal and coal slime in thermal power plants. It is widely used and stores raw coal or processed coal blocks. During output, bridging between materials can easily occur, causing coal blockage. To ensure smooth raw coal conveying during operation, a vibrating device is used to loosen the blockage and ensure the stability of the conveyed raw coal. However, it still has the following drawbacks in actual use:

[0003] When the anti-blocking rapping device of the raw coal bunker is working, it directly loosens the vibrating raw coal. After the raw coal is loosened, it is transported. During the transportation of raw coal, if the coal blocks are too large, it is easy to cause blockage and affect the uniformity of transportation. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-blocking rapping device for raw coal bunkers to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A clogging-prevention vibrating device for a raw coal bunker includes a storage base, which is hemispherical and has a storage cavity inside. A vibrating block, also hemispherical, is installed inside the storage cavity. The bottom surface of the vibrating block is in contact with the bottom surface of the storage cavity. The vibrating block has a hollow interior. Four sets of sliding grooves are formed on the surface of the vibrating block, and these grooves communicate with the hollow interior. Vibrating plates slide inside each groove. A pair of connecting rods are installed inside the hollow interior. A first driving member is positioned between the pair of connecting rods. The first driving member periodically compresses the four sets of vibrating plates. The vibrating plates and the pair of connecting rods are elastically connected. The bottom surface of the storage seat has a discharge port, and a blocking plate slides inside the discharge port. A feeding pipe is installed on the bottom surface of the storage seat, and a second driving component is installed inside the feeding pipe. The second driving component drives the blocking plate to move vertically. A conical cavity is provided inside the feeding pipe near its top, and the conical cavity is connected to the discharge port. The storage seat is fixed to the ground by a fixing frame. At the same time, the free end of the feeding pipe is connected to a mechanism for receiving raw coal. After the vibrating plate moves to its maximum distance, part of it is still in the cavity. Therefore, there is no large space between the vibrating plate and the chute to prevent raw coal from falling into the cavity from this space.

[0007] Furthermore, the first driving component includes a motor mounted on one of the connecting rod end faces, the output end of the motor being drivenly connected to a turntable, four sets of protrusions being equidistantly mounted on the side of the turntable, a pair of fixing rods being mounted on the side of the vibrating plate, a fixing plate being connected between the pair of fixing rods, the protrusions pressing against the fixing plate, and a spring connecting the fixing plate and the connecting rod.

[0008] Furthermore, the top surface of the rapping block is provided with several heat dissipation holes.

[0009] Furthermore, a first electric telescopic rod is provided above the vibrating block. The telescopic end of the first electric telescopic rod is connected to the center of the top surface of the vibrating block. The first electric telescopic rod is fixed by a frame, which is fixed to the ground. After the vibration is completed, the first electric telescopic rod shortens and drives the vibrating block to rise, thereby exposing the discharge port.

[0010] Furthermore, the second driving component includes a cross-shaped component installed inside the feed tube, with a second electric telescopic rod mounted on the top surface of the cross-shaped component. The telescopic end of the second electric telescopic rod is connected to the bottom surface of the blocking plate, and the cross-shaped component is located below the conical cavity.

[0011] Furthermore, the top surface of the blocking plate is an upwardly convex arc surface.

[0012] Furthermore, an air hood is installed on the outside of the feeding pipe, an air cavity is opened inside the air hood, an air nozzle is installed on the inner wall of the air hood, the air nozzle is located inside the feeding pipe and below the conical cavity, an air groove is opened on the bottom surface of the air nozzle, the air groove is connected to the air cavity, and an air inlet is opened on the outside of the air hood, the air inlet is connected to the air cavity.

[0013] Compared with existing technologies, the advantages of this invention are as follows: The anti-clogging vibration device for the raw coal bunker features a cleverly designed structure of vibration blocks and plates within the storage seat. The first driving component drives the turntable to rotate, and the protrusions on the turntable periodically press against the fixed plate, causing the vibration plates to reciprocate within the chute, effectively loosening the raw coal in the storage chamber. This design prevents raw coal from caking and bridging, ensuring smooth discharge from the storage seat and effectively solving the problem of poor conveying caused by raw coal caking in traditional devices, thus improving the discharge efficiency of the raw coal bunker.

[0022] Example

[0023] Figure 1-2An anti-clogging rapping device for a raw coal bunker provided in this application embodiment includes a storage base 1, which is hemispherical and has a storage cavity inside. A rapping block 5 is disposed inside the storage cavity. The bottom surface of the rapping block 5 is hemispherical and fits against the bottom surface of the storage cavity. The rapping block 5 has a cavity inside. Four sets of sliding grooves 15 are formed on the surface of the rapping block 5, and the sliding grooves 15 communicate with the cavity. A rapping plate 6 slides inside each of the sliding grooves 15. A pair of connecting rods 11 are installed inside the cavity. A first driving element is provided between a pair of connecting rods 11. The first driving element periodically squeezes four sets of vibrating plates 6. The vibrating plates 6 and the pair of connecting rods 11 are elastically connected. The bottom surface of the storage seat 1 has a discharge port, and a blocking plate 16 slides inside the discharge port. A feeding pipe 2 is installed on the bottom surface of the storage seat 1, and a second driving element is installed inside the feeding pipe 2. The second driving element drives the blocking plate 16 to move vertically. The inside of the feeding pipe 2 has a conical cavity near its top, and the conical cavity is connected to the discharge port. During operation, the storage seat 1 is used to store raw coal, and its hemispherical design facilitates the sliding of raw coal. After the first driving element is started, it drives the turntable 12 to rotate. The protrusions 13 on the turntable 12 periodically squeeze the fixing plate 10, causing the vibrating plates 6 to reciprocate in the sliding groove 15. The vibrating plates 6 and the connecting rods 11 are elastically connected by springs 14. The reciprocating motion of the vibrating plate 6 can beat the raw coal, thereby loosening the raw coal in the storage chamber and preventing it from clumping or bridging and clogging the discharge port. Simultaneously, the second drive unit controls the vertical movement of the blocking plate 16. After the raw coal is loosened, the second electric telescopic rod 20 extends, the blocking plate 16 descends to open the discharge port, and the raw coal enters the feed pipe 2 under gravity. The conical cavity at the top of the feed pipe 2 guides the raw coal smoothly into the feed pipe 2, preventing blockage.

[0024] In one embodiment of this utility model, the first driving component further includes a motor mounted on the end face of one of the connecting rods 11. The output end of the motor is connected to a turntable 12. Four sets of protrusions 13 are evenly spaced on the side of the turntable 12. A pair of fixing rods 9 are mounted on the side of the vibrating plate 6. A fixing plate 10 is connected between the pair of fixing rods 9. The protrusions 13 press against the fixing plate 10, and a spring 14 is connected between the fixing plate 10 and the connecting rod 11. The motor is mounted on the end face of the connecting rod 11, and the operation of the motor drives the turntable 12 to rotate. The protrusions 13 evenly distributed on the side of the turntable 12 will rotate with the turntable 12. When the protrusions 13 rotate to contact the fixing plate 10, they will press against the fixing plate 10. Since the fixing plate 10 is connected to the connecting rod 11 by the spring 14, when the protrusions 13 press against the fixing plate 10, the spring 14 is stretched, and the vibrating plate 6 slides within the groove 15 under force. When the protrusions 13 rotate away from the fixing plate 10, the spring 14 returns to its original deformation, causing the vibrating plate 6 to reset. This cycle repeats, achieving the periodic reciprocating motion of the vibrating plate 6, continuously loosening the raw coal.

[0025] As an embodiment of this utility model, the top surface of the rapping block 5 is provided with a plurality of heat dissipation holes 8. During the operation of the rapping block 5, the motor operation and the reciprocating motion of the rapping plate 6 will generate heat. The heat dissipation holes 8 on the top surface of the rapping block 5 can dissipate the heat to the outside, avoid the device temperature from being too high due to heat accumulation, and avoid affecting the normal operation of the motor and other components, thus ensuring the stability and service life of the device.

[0026] In one embodiment of this utility model, a first electric telescopic rod 7 is further provided above the vibrating block 5. The telescopic end of the first electric telescopic rod 7 is connected to the center of the top surface of the vibrating block 5, and is fixed to the ground by a frame. During the vibrating operation, the first electric telescopic rod 7 remains extended, allowing the vibrating block 5 to be stably positioned in the storage chamber for vibrating operations. After vibrating, the first electric telescopic rod 7 shortens, causing the vibrating block 5 to rise and expose the discharge port, facilitating the smooth discharge of raw coal and preventing the vibrating block 5 from obstructing the discharge of raw coal.

[0027] As an embodiment of this utility model, the second driving component further includes a cross 19 installed inside the feed pipe 2. A second electric telescopic rod 20 is installed on the top surface of the cross 19. The telescopic end of the second electric telescopic rod 20 is connected to the bottom surface of the blocking plate 16. The cross 19 is located below the conical cavity. The second driving component is installed inside the feed pipe 2, where the cross 19 serves to support the second electric telescopic rod 20. The telescopic end of the second electric telescopic rod 20 is connected to the bottom surface of the blocking plate 16. When it is necessary to open the discharge port, the second electric telescopic rod 20 extends, pushing the blocking plate 16 down, opening the discharge port, and the raw coal enters the feed pipe 2 from the discharge port. Due to the existence of the conical cavity, after the blocking plate 16 is lowered to the position, there is a large gap between it and the inner wall of the feed pipe 2, allowing the raw coal to pass through the gap and the cross 19 and fall out of the feed pipe 2. When it is necessary to close the discharge port, the second electric telescopic rod 20 shortens, pulling the blocking plate 16 up to block the discharge port and control the discharge rhythm of the raw coal.

[0028] As an embodiment of this utility model, the top surface of the blocking plate 16 is an upwardly convex arc surface. The top surface of the blocking plate 16 is designed to be an upwardly convex arc surface. When raw coal is piled up on the blocking plate 16, the arc surface structure allows the raw coal to slide naturally to the surroundings, avoiding the accumulation of raw coal on the blocking plate 16, reducing the risk of clogging the discharge port, and ensuring smooth discharge.

[0029] As an embodiment of this utility model, a gas hood 3 is further installed on the outside of the feeding pipe 2. An air chamber 17 is opened inside the gas hood 3. An air nozzle 18 is installed on the inner wall of the gas hood 3. The air nozzle 18 is located inside the feeding pipe 2 and below the conical cavity. An air groove 21 is opened on the bottom surface of the air nozzle 18. The air groove 21 is connected to the air chamber 17. An air inlet 4 is opened on the outside of the gas hood 3. The air inlet 4 is connected to the air chamber 17. When gas is introduced into the air chamber 17, the gas is sprayed out from the air nozzle 18 through the air groove 21. The sprayed gas can fluidize the raw coal in the feeding pipe 2, reduce the friction between the raw coal particles, enhance the fluidity, and further prevent the raw coal from clogging the feeding pipe 2 during the transportation process, ensuring the uniformity and stability of the raw coal transportation.
