Description

Technical Field

[0001] This utility model relates to the field of anti-blocking devices, specifically a multi-stage anti-blocking material device for coal conveying chutes in coking plants. Background Technology

[0002] In the coking process, the efficiency of coal conveying directly affects the stable operation and production efficiency of the coking oven. However, due to the uneven particle size, large moisture variation and easy adhesion of coal, traditional chutes often experience conveying interruptions due to poor coal flow or blockage. This not only increases the cost of manual cleaning but may also cause equipment failure or production delays. Therefore, designing a multi-stage anti-blocking device that can adaptively adjust and effectively prevent blockage is of great significance for improving the reliability and production efficiency of the coal conveying system in coking plants.

[0003] Traditional anti-clogging structures for coal chutes often employ single vibration or airflow impact methods, which have limited effectiveness in disturbing coal accumulation at bends, leading to frequent clogging problems. This not only requires frequent manual cleaning, increasing labor intensity, but also causes production interruptions due to downtime, reducing overall production efficiency. Furthermore, traditional chutes are often integral structures, with anti-clogging components built-in and tightly connected to the chute body, requiring significant time for disassembly and maintenance, increasing equipment maintenance costs. In addition, traditional devices lack real-time monitoring of material levels and automatic adjustment of feeding speed, making them prone to exacerbating clogging due to uncontrolled feed rates, further affecting the continuity and stability of coal conveying. Therefore, we propose a multi-stage anti-clogging device for coking plant coal chutes. Utility Model Content

[0018] 1. This multi-stage anti-blocking device for the coal conveying chute of the coking plant, by setting up a multi-stage anti-blocking structure, can solve the problem of material blockage more efficiently than the traditional single anti-blocking method.

[0038] Structural Description:

[0039] Bending pipe 1: Bending pipe 1 is the main channel for coal transportation. It has a chute inside and is a tubular component with a bending structure. The upper end fixed flange 4 is used to connect to the head cover 2. A sliding hole is opened near the outer wall of the head cover 2. Its bending structure is adapted to the coal transfer path. The chute undertakes the function of coal flow. The sliding hole provides sliding space for the fixed rod 12. It is the installation carrier of the anti-blocking component, supports the vibrator 11 and other components, and ensures the stable operation of the anti-blocking operation.

[0040] Head cover 2: The head cover 2 is a key component of the feed end. It is L-shaped and has a chute inside. The bottom end is fixed with flange 4 and connected to the bent pipe 1. The top surface is equipped with level gauge 3 and feed port fixed with bracket 6. Its L-shaped structure guides coal into the bent pipe 1. The chute and the bent pipe 1 chute are connected to form a conveying channel, providing the installation foundation for level gauge 3 and feeding mechanism. It is the support and guiding structure of the feed end.

[0041] Level gauge 3: Level gauge 3 is a material monitoring component, which is fixedly installed on the top surface of the head cover 2 with the sensor facing the feeding direction. It monitors the coal level in the head cover 2 in real time through the sensor, providing a basis for adjusting the speed of the feeding mechanism, avoiding material blockage caused by excessive feeding, and is a monitoring device to ensure stable coal conveying.

[0042] Flange 4: Flange 4 is a connecting component, which is fixed to the upper end face of the bent pipe 1 and the bottom end face of the machine head cover 2 respectively. It has holes for bolts 5 to pass through. By passing the bolts 5 through the corresponding flange 4, the bent pipe 1 and the machine head cover 2 are tightly connected to ensure smooth docking of the two chutes. It is a key structure to realize the detachable connection of components and ensure the convenience of device assembly and maintenance.

[0043] Bolt 5: Bolt 5 is a fastening connector that passes through the flange 4 on the bent pipe 1 and the head cover 2. It is used with a nut to fix the two together. The preload generated by the threaded connection ensures that the bent pipe 1 and the head cover 2 are firmly connected, preventing the components from loosening due to vibration during coal conveying, and ensuring the sealing of the chute connection. It is the core fastener for achieving reliable connection of components.

[0044] Fixed frame 6: Fixed frame 6 is the mounting carrier of the feeding mechanism. It is fixed to the feed inlet of the head cover 2. It is a frame structure with symmetrical front and rear rotating pulleys 7 inside. A motor 9 is installed on one side of the outer wall. Its frame structure provides support and limit for the pulleys 7, synchronous belts 8, etc., to ensure the stable operation of the feeding mechanism. It is a supporting component connecting the head cover 2 and the feeding mechanism.

[0045] Pulley 7: Pulley 7 is a transmission component. There are two of them, which are symmetrically rotatably connected in the fixed frame 6 and are connected to the synchronous belt 8 for transmission. One of them is fixed coaxially with the output shaft of the motor 9. When the motor 9 drives it to rotate, it drives the other pulley 7 to rotate synchronously through the synchronous belt 8, realizing power transmission and enabling the synchronous belt 8 to stably transport coal. It is the core transmission component of the feeding mechanism.

[0046] Synchronous belt 8: Synchronous belt 8 is a feeding execution component. It is connected between two pulleys 7 and located at the feed inlet of the head cover 2. Driven by the pulleys 7, it circulates and smoothly transports the coal into the chute of the head cover 2. Its smooth transmission can avoid the impact and accumulation of coal during transportation. It is a key component for controlling the feeding speed.

[0047] Motor 9: Motor 9 is the power source of the feeding mechanism. It is fixed on the outer wall of one side of the fixed frame 6. The output shaft is coaxially fixed with a pulley 7. The output shaft rotates to provide power to the pulley 7, which drives the synchronous belt 8 to run and realize coal conveying. Its speed can be adjusted to control the feeding speed. It is the core component to ensure the automated operation of the feeding mechanism.

[0048] Air Cannon 10: Air Cannon 10 is an anti-blocking auxiliary component, fixed on the outer wall of the section of the bent pipe 1 near the head cover 2, located above the anti-blocking component, with the nozzle facing the material discharge direction of the head cover 2. It can instantly spray high-pressure airflow to impact the coal accumulated at the bend. Combined with the vibrator 11, it enhances the anti-blocking effect. The airflow impact force disperses the sticky or accumulated coal material, reducing the risk of material blockage.

[0049] Vibrator 11: Vibrator 11 is the core component for preventing blockage. It is fixed on the support plate near the bend of the bent pipe 1. One end extends into the chute and is connected to the movable plate 14. When working, it generates vibration and transmits it to the movable plate 14, so that the movable plate 14 continuously disturbs the coal in the chute and breaks up the accumulated coal. It is the power source for preventing blockage through vibration and ensures smooth coal transportation.

[0050] Fixed rod 12: Fixed rod 12 is a guide component of movable plate 14. There are two rods in total. They are symmetrically fixed on the side of movable plate 14 facing vibrator 11. They are slidably connected to the sliding hole of bent pipe 1. During vibration, they guide movable plate 14 to move in a fixed direction to avoid it from deviating or shaking, ensuring that the disturbance effect of movable plate 14 on coal is stable and enhancing the structural stability of anti-blocking component.

[0051] Spring 13: Spring 13 is an elastic buffer component, symmetrically fixed on the side of the movable plate 14 facing the vibrator 11, corresponding to both sides of each fixed rod 12, and the other end is connected to the inner wall of the chute of the bent pipe 1. When the movable plate 14 vibrates, the spring 13 generates elastic force through extension and contraction to assist its reset, enhance the vibration amplitude and frequency, and at the same time buffer the impact force of vibration on the bent pipe 1, protecting the component structure.

[0052] Movable plate 14: Movable plate 14 is the anti-blocking actuator, located in the chute of the bent pipe 1, and fixed to one end of the vibrator 11 that extends into the chute. It is connected to the side of the fixed rod 12 and the spring 13. It vibrates under the drive of the vibrator 11, directly contacting the coal and disturbing the accumulated material. Its planar structure can expand the disturbance range. Together with the spring 13 and the fixed rod 12, it can achieve stable vibration. It is the core actuator of the anti-blocking component.

[0053] Working principle: When working, the motor 9 starts, and its output shaft drives the pulley 7, which is fixed on the same axis, to rotate. Through the transmission action of the synchronous belt 8, the other pulley 7 rotates synchronously, so that the synchronous belt 8 circulates in the fixed frame 6, and smoothly conveys the coal to the feed port of the head cover 2. The stable operation of the feeding mechanism can avoid the accumulation caused by sudden changes in the coal feeding speed. The material level gauge 3 on the top surface of the head cover 2 monitors the internal coal material level in real time. If the material level is too high, the feeding speed of the synchronous belt 8 can be reduced by adjusting the speed of the motor 9 to prevent excessive feeding and blockage.

[0054] After the coal enters the chute of the bent pipe 1 through the chute of the head cover 2, the anti-blocking component starts to work. The vibrator 11 starts to generate vibration, which drives the movable plate 14 fixed thereto to vibrate in the chute of the bent pipe 1. When the movable plate 14 vibrates, the fixed rod 12 on its side slides coaxially along the sliding hole of the bent pipe 1 to ensure that the movable plate 14 moves in a fixed direction and avoids deviation. At the same time, the spring 13 on the same side of the movable plate 14 extends and retracts with the vibration, and assists the movable plate 14 to return to its original position through elastic force. This not only enhances the vibration amplitude and frequency, but also buffers the impact force of the vibration on the bent pipe 1, so that the movable plate 14 can continuously disturb the coal accumulated at the bend and break up the lumps or piles of coal.

[0055] During this process, the air cannon 10 located above the anti-blocking component will spray high-pressure airflow in a timely manner, with the nozzle facing the material discharge direction of the head cover 2. The airflow directly impacts the coal in the bent pipe 1, forming a dual effect with the vibration of the movable plate 14, further dispersing the sticky or accumulated coal material and greatly reducing the probability of blockage. The bent pipe 1 and the head cover 2 are tightly connected by the flange 4 and bolts 5 to ensure smooth docking of the two chutes, and the coal can flow smoothly from the head cover 2 into the bent pipe 1. The entire conveying path is stable and continuous.

[0056] Through the uniform feeding of the feeding mechanism, the real-time monitoring and adjustment of the level gauge 3, the coordinated anti-blocking of the anti-blocking components by vibration and airflow impact, and the stable whole formed by the connection structure of each component through flange 4, bolt 5, etc., the device realizes continuous and efficient coal transportation, effectively solves the problems of frequent material blockage and inconvenient maintenance of traditional devices, and significantly improves the reliability and production efficiency of the coal transportation system of the coking plant.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
