Description

Technical Field

[0001] This utility model relates to the technical field of vibratory conveying equipment for calcined petroleum coke, and in particular to a conveying trough for a vibratory conveyor of calcined petroleum coke. Background Technology

[0002] Petroleum coke is a product obtained by separating light and heavy oils from crude oil through distillation, followed by thermal cracking of the heavy oil. Petroleum coke produced from petroleum coke plants is called raw coke, containing some uncarbonized volatile hydrocarbons. Raw coke can be used as fuel-grade petroleum coke. However, if it is to be used as an anode in aluminum smelting or an electrode in steelmaking, it needs to be calcined at high temperatures to complete carbonization and reduce the volatile content to a minimum.

[0003] 1. Tank: This is the main part for conveying materials. It is generally made of metal materials, such as high-temperature resistant steel. Its shape and size are determined according to the conveying capacity and process requirements.

[0004] 2. Reinforcing ribs: To enhance the structural strength of the conveying trough and prevent deformation under vibration and material pressure, reinforcing ribs are installed on the trough body;

[0005] 3. Support structure: Used to support the feed trough and ensure its stability, usually consisting of steel beams or other sturdy support components.

[0006] For example, a Chinese patent discloses a feeding trough for a vibratory conveyor of calcined petroleum coke (patent number: CN213010322U). The feeding trough is installed on the vibratory conveyor via a connecting frame. The material is placed in the inner trough. During the conveying process, the vibratory conveyor provides vibration. The bottom of the inner trough is connected by a sliding embedded connecting protrusion, and the top is connected to the feeding trough by a spring. This causes the inner trough to swing within the feeding trough, thereby causing the material to be conveyed by bumping and swaying within the inner trough, effectively reducing adhesion and improving conveying efficiency.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: As mentioned above, the conveying trough is square. During the conveying process, petroleum coke may get stuck in the inner corner of the square. The spring's rebound is not strictly in accordance with its own initial shape, which will aggravate the fatigue of the spring. The degree of bumping in the trough will also be limited, and a lot of petroleum coke will still stick to its inner wall. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides a feeding trough for a vibrating conveyor of calcined petroleum coke, which solves the technical problems mentioned above. The feeding trough is square, and during the conveying process, petroleum coke may get stuck in the inner corners of the square. The spring's rebound is not strictly in accordance with its original shape, which will aggravate the spring fatigue. In addition, the degree of bumping inside the trough will also be limited, and a lot of petroleum coke will still stick to its inner wall.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A vibratory conveyor trough for calcined petroleum coke includes a U-shaped trough. A vibration damping mechanism is installed inside the U-shaped trough. The vibration damping mechanism includes a triangular block, a silicon nitride coating, a first spring, a second spring, a connecting column, and an outer trough. The triangular block is fixedly installed inside the U-shaped trough. The silicon nitride coating is disposed inside the U-shaped trough. The first spring and the second spring are fixedly installed on the side wall of the U-shaped trough. The connecting column is rotatably installed at the bottom of the U-shaped trough, and the outer trough is rotatably installed at the bottom of the connecting column.

[0013] Preferably, a reinforcing rib is fixedly installed inside the outer groove of the conveying trough, and a connecting plate is fixedly installed on the top of the U-shaped trough.

[0014] Preferably, a fixing plate is fixedly installed on the side wall of the connecting plate, and a third spring is fixedly installed at the bottom of the fixing plate.

[0015] Preferably, a sliding plate is fixedly installed at the bottom of the third spring, and the sliding plate is slidably installed on the side wall of the connecting plate.

[0016] Preferably, the side wall of the fixing plate is hinged with a hinge plate.

[0017] Preferably, the end of the fixed plate and the sliding plate near the hinge plate is an inclined surface.

[0018] (III) Beneficial Effects

[0019] 1. The U-shaped trough vibrates with the vibrating conveyor. When petroleum coke falls into the U-shaped trough, it is conveyed inside. When the petroleum coke comes into contact with the triangular block, it will be separated to the left and right sides (at this time, the weight difference between the left and right ends makes the U-shaped trough shake more violently, increasing the vibration during the transmission process). Due to the triangular block (its low surface energy, weak intermolecular forces with other substances, good chemical stability, and is not easy to react with other substances, and its coating surface is usually smooth, reducing the contact area and friction, and its high hardness and good wear resistance, making it not easy to be worn or scratched, and maintaining its non-adhesive properties for a long time), the petroleum coke is difficult to adhere to the inner wall of the U-shaped trough. The asymmetrical installation of the second spring and the first spring (the asymmetrical layout will lead to unbalanced forces, making the restoring force of the vibration system different in different directions, thus producing more complex and strong vibrations, enhancing the amplitude and frequency of vibration, and improving the vibration effect) increases the vibration amplitude of the device during the conveying process, thus making it difficult for the petroleum coke to adhere to the inside of the U-shaped trough.

[0020] 2. When the petroleum coke comes into contact with the hinge plate, it will fall along the inclined surface of the hinge plate into the U-shaped groove. The frequency and amplitude of the device vibration are relatively large. The petroleum coke sways left and right along the inside of the U-shaped groove. When the petroleum coke hits the sliding plate, the sliding plate drives the third spring to be compressed. When the third spring rebounds, it drives the sliding plate to move from top to bottom. At this time, the sliding plate applies force to the petroleum coke, which will accelerate its movement, increase the vibration of the device, and prevent the petroleum coke from flying out of the U-shaped groove. The upward movement of the sliding plate will also drive the hinge plate to flip from the middle to both sides. The hinge plate will prevent the petroleum coke from entering between the fixed plate and the sliding plate and getting stuck inside the third spring. Attached Figure Description

[0027] This application provides a feeding trough for a vibrating conveyor of calcined petroleum coke, effectively solving the problems mentioned above. The feeding trough is square, and during conveying, petroleum coke may get stuck in the inner corners. The spring's rebound is not strictly in line with its initial shape, which exacerbates spring fatigue. Furthermore, the degree of vibration within the trough is limited, and a significant amount of petroleum coke still adheres to its inner wall. The U-shaped trough vibrates with the vibrating conveyor. When petroleum coke falls into the U-shaped trough, it is conveyed within it. When the petroleum coke contacts the triangular blocks, it is separated to the left and right sides (at this time, the weight difference between the left and right ends makes the U-shaped trough shake more violently, increasing the vibration during transmission). Due to the triangular blocks (which have low surface energy, weak intermolecular forces with other substances, good chemical stability, and are not prone to chemical reactions with other substances; their coating surface is usually smooth, reducing the contact area and friction; in addition, their high hardness and good wear resistance make them less susceptible to wear or scratches, maintaining non-adhesive properties for a long time), petroleum coke... The coke is difficult to adhere to the inner wall of the U-shaped groove. The asymmetrical installation of the second spring and the first spring (the asymmetrical layout leads to unbalanced forces, resulting in different restoring forces in different directions of the vibration system, thus generating more complex and intense vibrations, enhancing the amplitude and frequency of vibration, and improving the vibration effect) increases the vibration amplitude of the device during conveying. As a result, the coke is difficult to adhere to the inside of the U-shaped groove. When the coke comes into contact with the hinge plate, it will fall into the U-shaped groove along the inclined surface of the hinge plate. The frequency and amplitude of the device vibration are relatively large. The coke sways left and right along the inside of the U-shaped groove. When the coke hits the sliding plate, the sliding plate drives the third spring to be compressed. When the third spring rebounds, it drives the sliding plate to move from top to bottom. At this time, the sliding plate applies force to the coke, which will accelerate the movement of the coke, increase the vibration of the device, and prevent the coke from flying out of the U-shaped groove. The upward movement of the sliding plate will also drive the hinge plate to flip from the middle to both sides. The hinge plate will prevent the coke from entering between the fixed plate and the sliding plate and getting stuck inside the third spring. Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problems mentioned above, where the conveying trough is square, and petroleum coke may get stuck in the inner corners of the square during the conveying process. The spring's rebound is not strictly in accordance with its initial shape, which will exacerbate spring fatigue and limit the degree of vibration within the trough, resulting in a significant amount of petroleum coke still adhering to its inner wall. The overall idea is as follows: A conveying trough for a vibrating conveyor of calcined petroleum coke includes a U-shaped trough 11. A vibration damping mechanism is provided inside the U-shaped trough 11. The vibration damping mechanism includes a triangular block 12, a silicon nitride coating 13, a first spring 14, a second spring 15, a connecting column 16, and an outer trough 17. The triangular block 12 is fixedly installed inside the U-shaped trough 11, the silicon nitride coating 13 is disposed inside the U-shaped trough 11, the first spring 14 is fixedly installed on the side wall of the U-shaped trough 11, the second spring 15 is fixedly installed on the side wall of the U-shaped trough 11, the connecting column 16 is rotatably installed at the bottom of the U-shaped trough 11, and the outer trough 17 is rotatably installed at the bottom of the connecting column 16. The U-shaped trough 11 vibrates with the vibrating conveyor. When petroleum coke falls into the U-shaped trough 11, it is conveyed inside the U-shaped trough 11. When the petroleum coke comes into contact with the triangular block 12, it will be separated to the left and right sides (at this time, the weight difference between the left and right ends makes the U-shaped trough 11 shake more violently, increasing the vibration during the transmission process). Due to the triangular block 12 (which has low surface energy, weak intermolecular forces with other substances, good chemical stability, and is not easy to react with other substances, and whose coating surface is usually smooth, reducing the contact area and friction, and whose high hardness and good wear resistance make it not easy to be worn or scratched, and can maintain non-adhesion performance for a long time), the petroleum coke is difficult to adhere to the inner wall of the U-shaped trough 11. The asymmetrical installation of the second spring 15 and the first spring 14 (the asymmetrical layout will lead to unbalanced force, making the restoring force of the vibration system different in different directions, thus producing more complex and strong vibration, enhancing the amplitude and frequency of vibration, and improving the vibration effect) increases the vibration amplitude of the device during the conveying process, thus making it difficult for the petroleum coke to adhere to the inside of the U-shaped trough 11.

[0029] The outer trough 17 of the conveying trough is fixedly installed with reinforcing ribs 18, which helps to suppress excessive deformation during vibration, maintain stability, and thus ensure the smoothness and accuracy of conveying.

[0030] A connecting plate 19 is fixedly installed at the top of the U-shaped groove 11. A fixing plate 21 is fixedly installed on the side wall of the connecting plate 19. A third spring 22 is fixedly installed at the bottom of the fixing plate 21. A sliding plate 23 is fixedly installed at the bottom of the third spring 22. The sliding plate 23 is slidably installed on the side wall of the connecting plate 19. A hinge plate 24 is hinged to the side wall of the fixing plate 21. The ends of the fixing plate 21 and the sliding plate 23 near the hinge plate 24 are inclined. When the petroleum coke comes into contact with the hinge plate 24, it will fall along the inclined surface of the hinge plate 24 into the U-shaped groove 11. The frequency and amplitude of the device vibration are relatively large, and the petroleum coke falls along the U-shaped groove. When the petroleum coke inside the U-shaped groove 11 shakes left and right and hits the sliding plate 23, the sliding plate 23 drives the third spring 22 to be compressed. When the third spring 22 rebounds, it drives the sliding plate 23 to move from top to bottom. At this time, the sliding plate 23 applies force to the petroleum coke, which will accelerate its movement, increase the vibration of the device, and prevent the petroleum coke from flying out of the U-shaped groove 11. The upward movement of the sliding plate 23 will also drive the hinge plate 24 to flip from the middle to both sides. The hinge plate 24 will prevent the petroleum coke from entering between the fixed plate 21 and the sliding plate 23 and getting stuck inside the third spring 22.

[0031] To address the problems existing in the prior art, this utility model provides a conveying trough for a vibrating conveyor of calcined petroleum coke. The U-shaped trough 11 vibrates with the vibrating conveyor. When petroleum coke falls into the U-shaped trough 11, it is conveyed inside the U-shaped trough 11. When the petroleum coke contacts the triangular block 12, it will be separated to the left and right sides (at this time, the weight difference between the left and right ends makes the shaking of the U-shaped trough 11 more violent, increasing the vibration during the transmission process). Due to the triangular block 12 (which has low surface energy, weak intermolecular forces with other substances, good chemical stability, and is not easy to react chemically with other substances, and whose coating surface is usually smooth, reducing the contact area and friction, and whose high hardness and good wear resistance make it not easy to be worn or scratched, and can maintain non-adhesive properties for a long time), the petroleum coke is difficult to adhere to the inner wall of the U-shaped trough 11. The second spring 15 and the first spring 14 are asymmetrically installed (the asymmetrical layout will lead to unbalanced force, causing the vibration system to vibrate in different directions). The different restoring forces on the surface result in more complex and intense vibrations, enhancing the amplitude and frequency of the vibration and improving the vibration effect. This increases the vibration amplitude of the device during conveying, making it difficult for petroleum coke to adhere to the inside of the U-shaped groove 11. When the petroleum coke comes into contact with the hinge plate 24, it will fall into the U-shaped groove 11 along the inclined surface of the hinge plate 24. The frequency and amplitude of the device vibration are relatively large. The petroleum coke sways left and right along the inside of the U-shaped groove 11. When the petroleum coke hits the sliding plate 23, the sliding plate 23 drives the third spring 22 to be compressed. When the third spring 22 rebounds, it drives the sliding plate 23 to move from top to bottom. At this time, the sliding plate 23 applies force to the petroleum coke, which will accelerate its movement, increase the vibration of the device, and prevent the petroleum coke from flying out of the U-shaped groove 11. The upward movement of the sliding plate 23 will also drive the hinge plate 24 to flip from the middle to both sides. The hinge plate 24 will prevent the petroleum coke from entering between the fixed plate 21 and the sliding plate 23 and getting stuck inside the third spring 22.

[0032] Working principle:

[0033] In the first step, the U-shaped trough 11 vibrates with the vibrating conveyor. When petroleum coke falls into the U-shaped trough 11, it is conveyed inside the U-shaped trough 11. When the petroleum coke comes into contact with the triangular block 12, it will be separated to the left and right sides (at this time, the weight difference between the left and right ends makes the U-shaped trough 11 shake more violently, increasing the vibration during the transmission process). Due to the triangular block 12 (which has low surface energy, weak intermolecular forces with other substances, good chemical stability, and is not easy to react with other substances, and whose coating surface is usually smooth, reducing the contact area and friction, and whose high hardness and good wear resistance make it not easy to be worn or scratched, and can maintain its non-adhesive performance for a long time), the petroleum coke is difficult to adhere to the inner wall of the U-shaped trough 11. The second spring 15 is asymmetrically installed with the first spring 14 (the asymmetrical layout will lead to unbalanced force, making the restoring force of the vibration system different in different directions, thus producing more complex and strong vibration, enhancing the amplitude and frequency of vibration, and improving the vibration effect), increasing the vibration amplitude of the device during the conveying process, so that the petroleum coke is difficult to adhere to the inside of the U-shaped trough 11.

[0034] In the second step, when the petroleum coke comes into contact with the hinge plate 24, it will fall along the inclined surface of the hinge plate 24 into the U-shaped groove 11. The frequency and amplitude of the device vibration are relatively large. The petroleum coke sways left and right along the inside of the U-shaped groove 11. When the petroleum coke hits the sliding plate 23, the sliding plate 23 drives the third spring 22 to be compressed. When the third spring 22 rebounds, the third spring 22 drives the sliding plate 23 to move from top to bottom. At this time, the sliding plate 23 applies force to the petroleum coke, which will accelerate its movement, increase the vibration of the device, and prevent the petroleum coke from flying out of the U-shaped groove 11. The movement of the sliding plate 23 from bottom to top will also drive the hinge plate 24 to flip from the middle to both sides. The hinge plate 24 will prevent the petroleum coke from entering between the fixed plate 21 and the sliding plate 23 and getting stuck inside the third spring 22.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
