Description

Technical Field

[0001] This utility model relates to the field of raw coal bunkers, specifically to a raw coal bunker anti-clogging discharge structure. Background Technology

[0002] The raw coal bunker is an important facility in thermal power plants for storing raw coal and other granular materials. Its design needs to take into account factors such as shape, structure, materials and anti-clogging. It is usually cylindrical or conical, tapering at the bottom to the coal feeder. The inner wall is smooth to reduce coal blockage. During operation, attention should be paid to the moisture content of the material, the running interval and the equipment temperature. Measures such as manual unblocking, loosening machines or rotary shovel anti-clogging and unblocking machines should be taken to deal with blockage.

[0003] Currently, there is a problem in the use of raw coal bunkers. Specifically, the discharge structure of traditional raw coal bunkers mostly adopts a single screw conveyor method. This structure makes it difficult to flexibly adjust the discharge position according to the actual use environment. Since the discharge position is relatively fixed, the adaptability of raw coal bunkers in different use scenarios is limited, which reduces the ease of use of its discharge structure. This problem not only affects the working efficiency of raw coal bunkers, but also increases the difficulty and cost of operation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a discharge structure for preventing blockage in raw coal bunkers, so as to solve the technical problem that the discharge position is difficult to adjust arbitrarily according to the usage environment and is subject to the usage environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw coal bunker anti-clogging discharge structure, comprising a raw coal bunker and a discharge mechanism, wherein the discharge mechanism comprises a first screw conveyor and a second screw conveyor, wherein the discharge port of the first screw conveyor and the inlet of the second screw conveyor are connected by a sleeve, and the connection between them is a rotatable structure, wherein a drive mechanism for rotating the second screw conveyor is installed below the second screw conveyor to adjust the position of the discharge port of the second screw conveyor.

[0006] By adopting the above technical solution, the sleeve of the first screw conveyor and the second screw conveyor can be rotatably connected, which realizes the flexible adjustment of the discharge port position of the second screw conveyor, greatly enhances the adaptability and flexibility of the discharge structure, and enables the raw coal bunker to achieve efficient discharge in different operating environments, effectively solving the problem of fixed discharge position and difficulty in adjustment of traditional raw coal bunkers.

[0007] Furthermore, the driving mechanism below the second screw conveyor includes a base and a turntable. The turntable is rotatably connected to the base, and the rotation point is coaxial with the sleeve between the first screw conveyor and the second screw conveyor.

[0008] By adopting the above technical solution, the drive mechanism ensures the stability and accuracy of the second screw conveyor during rotation, which not only improves the accuracy of the outlet position adjustment, but also reduces the additional stress and wear caused by unstable rotation, and extends the service life of the equipment.

[0009] Furthermore, a first gear and a second gear are provided between the turntable and the base, with the second gear fixedly connected to the turntable, and the first gear and the second gear meshing for transmission.

[0010] By adopting the above technical solution, a reliable power transmission method is provided for the rotation of the second screw conveyor. This transmission method has the advantages of high transmission efficiency and stable transmission ratio, which can ensure that the second screw conveyor maintains a constant speed and torque during rotation, thereby achieving precise adjustment of the discharge port position.

[0011] Furthermore, a first motor is installed on one side above the turntable, and the output end of the first motor is connected to the first gear transmission. The second screw conveyor is bolted to the turntable.

[0012] By adopting the above technical solution, a convenient and efficient power source is provided for the rotation of the second screw conveyor. The first motor can precisely control the rotation angle and speed of the second screw conveyor by controlling the speed and direction, thereby realizing flexible adjustment of the discharge port position.

[0013] Furthermore, a cavity is formed on the inner side of the raw coal bunker, a feeding port is formed on the top of the raw coal bunker, and maintenance ports are provided on both sides of the lower part of the raw coal bunker.

[0014] By adopting the above technical solution, the cavity provides ample space for the storage of raw coal, ensuring that the raw coal bunker can hold enough raw coal to meet the needs of long-term, continuous production. At the same time, the feeding port set above the raw coal bunker facilitates the addition and replenishment of raw coal, improves feeding efficiency, and reduces the difficulty of manual operation.

[0015] Furthermore, an anti-clogging mechanism is provided above the first screw conveyor. The anti-clogging mechanism includes a shaft, and several paddles are installed on the outer side of the shaft. Both ends of the shaft are rotatably installed with the raw coal bunker. A second motor is installed on one side of the raw coal bunker, and the second motor is connected to the shaft in a transmission connection.

[0016] By adopting the above technical solution, the anti-clogging mechanism continuously agitates and loosens the raw coal through the rotational movement of the shaft and several paddles, effectively preventing the raw coal from clumping and clogging in the bin. This not only improves the fluidity of the raw coal but also reduces the resistance during the discharge process, allowing the raw coal to be discharged smoothly through the discharge mechanism.

[0017] Furthermore, both the first motor and the second motor are electrically connected to an external power source via a controller.

[0018] By adopting the above technical solution, intelligent control of the discharge structure and anti-blocking mechanism is realized. Through the controller, the operator can remotely adjust the motor's operating status, such as speed and direction, thereby accurately controlling the discharge port position and the stirring frequency of the anti-blocking mechanism. This intelligent control method not only improves the automation level of the equipment, but also reduces the difficulty and labor intensity of manual operation.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention enables flexible adjustment of the discharge port position of the second screw conveyor through its discharge mechanism. This flexibility is crucial for adapting to the discharge requirements of different operating environments. Whether in confined spaces or complex layouts, the discharge process can be optimized and discharge efficiency improved by adjusting the discharge port position. Simultaneously, the first motor in the drive mechanism outputs rotational power, which drives the turntable to rotate through the meshing of the first and second gears, thereby driving the second screw conveyor to rotate. This transmission method is not only compact and efficient, but also enables precise rotation control, making the adjustment of the discharge port position more accurate and reliable. The adjustability of the raw coal bunker's discharge port is significantly improved, and its ease of use is also enhanced, providing a strong guarantee for the widespread application and efficient operation of the raw coal bunker.

[0021] This invention utilizes an anti-clogging mechanism, a second motor driving a shaft and several paddles to rotate, effectively agitating the raw coal and preventing it from clumping and clogging in the storage bin. It provides a proactive solution to the clogging problem that easily occurs during the storage and transportation of raw coal, ensuring the smooth flow of raw coal and improving discharge efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example

[0028] A raw coal bunker anti-clogging discharge structure, such as Figure 1-4 As shown, the system includes a raw coal bunker 1 and a discharge mechanism 2. The discharge mechanism 2 includes a first screw conveyor 201 and a second screw conveyor 202. The discharge port of the first screw conveyor 201 and the inlet of the second screw conveyor 202 are connected by a sleeve 203, and the connection between them is rotatable. A drive mechanism is installed below the second screw conveyor 202 to adjust the position of its discharge port. The rotatable connection between the sleeve 203 of the first screw conveyor 201 and the second screw conveyor 202 allows for flexible adjustment of the discharge port position of the second screw conveyor 202, greatly enhancing the adaptability and flexibility of the discharge structure. This enables the raw coal bunker to achieve efficient discharge in different operating environments, effectively solving the problem of fixed and difficult-to-adjust discharge position in traditional raw coal bunkers. At the same time, by optimizing the discharge process, the risk of blockage during the discharge process is reduced, and the discharge efficiency is improved, providing a strong guarantee for the stable operation of the raw coal bunker.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The drive mechanism below the second screw conveyor 202 includes a base 205 and a turntable 204. The turntable 204 is rotatably connected to the base 205, and the rotation point is coaxial with the sleeve 203 between the first screw conveyor 201 and the second screw conveyor 202. The drive mechanism ensures the stability and accuracy of the second screw conveyor 202 during rotation, which not only improves the accuracy of the outlet position adjustment, but also reduces the additional stress and wear caused by unstable rotation, and extends the service life of the equipment. At the same time, the coaxial arrangement makes the entire discharge structure more compact and reasonable, which is convenient for installation and maintenance and reduces operating costs.

[0030] See Figure 3, Figure 4 A first gear 207 and a second gear 208 are provided between the turntable 204 and the base 205. The second gear 208 is fixedly connected to the turntable 204. The first gear 207 and the second gear 208 mesh and drive each other, providing a reliable power transmission method for the rotation of the second screw conveyor 202. This transmission method has the advantages of high transmission efficiency and stable transmission ratio, which can ensure that the second screw conveyor 202 maintains a constant speed and torque during rotation, thereby achieving precise adjustment of the discharge port position. At the same time, the gear transmission mechanism also has high load-bearing capacity and wear resistance, which can adapt to the requirements of long-term and high-intensity operation, ensuring the stability and reliability of the discharge structure.

[0031] See Figure 3 , Figure 4 A first motor 206 is installed on one side above the turntable 204, and the output end of the first motor 206 is connected to the first gear 207 for transmission. The second screw conveyor 202 is bolted to the turntable 204, providing a convenient and efficient power source for the rotation of the second screw conveyor 202. By controlling the speed and direction of rotation, the first motor 206 can precisely control the rotation angle and speed of the second screw conveyor 202, thereby realizing flexible adjustment of the discharge port position. At the same time, the bolted installation method of the second screw conveyor 202 and the turntable 204 makes the assembly and disassembly of the entire discharge structure simpler and faster, facilitates the maintenance and replacement of the equipment, and improves the maintainability and efficiency of the equipment.

[0032] See Figure 1 , Figure 2 The raw coal bunker 1 has an inner cavity, a feeding port 3 at the top, and inspection ports 5 on both sides of its lower part. The cavity provides ample space for storing raw coal, ensuring that the bunker can hold enough raw coal to meet the needs of long-term, continuous production. At the same time, the feeding port 3 at the top of the bunker facilitates the addition and replenishment of raw coal, improving feeding efficiency and reducing the difficulty of manual operation. In addition, the inspection ports 5 on both sides of the bunker provide convenient conditions for daily maintenance and repair of the equipment, allowing staff to easily enter the bunker for inspection, cleaning, and maintenance, ensuring the stable operation of the bunker and extending its service life. Example

[0033] See Figure 1 , Figure 2An anti-blocking mechanism 4 is installed above the first screw conveyor 201. The anti-blocking mechanism 4 includes a shaft 401, with several paddles 402 installed on the outer side of the shaft 401. Both ends of the shaft 401 are rotatably installed with the raw coal bunker 1. A second motor 403 is installed on one side of the raw coal bunker 1. The second motor 403 is connected to the shaft 401 through transmission. The anti-blocking mechanism 4 continuously agitates and loosens the raw coal through the rotational movement of the shaft 401 and the paddles 402, effectively preventing the raw coal from clumping and blocking in the bunker. This not only improves the fluidity of the raw coal but also reduces the resistance during the discharge process, allowing the raw coal to be discharged smoothly through the discharge mechanism 2. At the same time, the rotatable installation of the anti-blocking mechanism 4 with the raw coal bunker 1 and the transmission connection of the second motor 403 ensure that the paddles 402 can rotate stably and efficiently, providing a reliable guarantee for the anti-blocking of the raw coal bunker.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Both the first motor 206 and the second motor 403 are electrically connected to an external power supply through a controller, realizing intelligent control of the discharge structure and the anti-blocking mechanism. Through the controller, the operator can remotely adjust the operating status of the motor, such as speed and direction, thereby precisely controlling the discharge port position and the stirring frequency of the anti-blocking mechanism. This intelligent control method not only improves the automation level of the equipment, but also reduces the difficulty and labor intensity of manual operation. At the same time, the controller can also perform real-time monitoring and fault warning based on the actual operating conditions of the equipment, promptly detect and handle potential problems, and ensure the stable operation and efficient discharge of the raw coal bunker discharge structure.

[0035] The implementation principle of this embodiment is as follows: The discharge mechanism 2 consists of a first screw conveyor 201 and a second screw conveyor 202, which are rotatably connected by a sleeve 203. This allows the discharge port position of the second screw conveyor 202 to be flexibly adjusted by the drive mechanism below to adapt to the discharge requirements under different operating environments. In the drive mechanism, the first motor 206 outputs rotational power through the meshing of the first gear 207 and the second gear 208 to drive the turntable 204 to rotate, thereby driving the second screw conveyor 202 to rotate. At the same time, an anti-blocking mechanism 4 is set above the first screw conveyor 201. The second motor 403 drives the shaft 401 and several paddles 402 to rotate to agitate the raw coal and prevent blockage. The entire system is intelligently controlled by a controller to ensure the efficiency, stability and convenience of the discharge process.
