Description

Technical Field

[0001] The invention relates to the technical field of coal supply in coal bunkers, and in particular to a coal conveying device capable of supplying a plurality of separated bunkers at the same time. Background Art

[0002] In order to meet the needs of flexible coal distribution and rapid peak regulation, thermal power plants usually add partitions in the middle of the coal bunker and transform the bunker into a partitioned bunker. This design allows high-quality coal to be stored on one side and low-quality coal to be stored on the other side, thereby realizing the diversified use of coal. Under normal circumstances, power plants use low-quality coal to generate electricity. However, when the grid dispatch requires a reduction in power generation, in order to ensure that the fire is not extinguished and maintain stable combustion, it is necessary to switch to high-quality coal. This partitioned bunker design switches the coal type by opening valves on different sides: when burning high-quality coal, the valve on one side is opened, and when burning low-quality coal, the valve on the other side is opened. This partitioned bunker design not only realizes the diversification of coal, but also improves the reliability of production. For example, during the peak production period, if one bunker is congested, the other bunker can still work normally, thus ensuring the continuity of production. This fully reflects the efficient use of resources and also highlights the importance of coal supply from the partitioned bunker in the entire production process. However, in actual production, it is often necessary to supply coal to a large number of partitioned bunkers placed side by side, which leads to a long length of the coal supply area. Conventional coal conveying devices are difficult to meet the demand for long-distance coal supply and cannot effectively supply coal to all compartments at the same time. In addition, existing coal conveying devices are generally inflexible and difficult to accurately distribute coal according to the needs of different compartments. Another problem is that existing coal conveying devices are often unable to supply coal to both sides of the compartment at the same time, which limits the efficiency of the compartment. Summary of the invention

[0003] In order to solve the above-mentioned defects, the purpose of the present invention is to provide a coal conveying device that can supply multiple compartments at the same time, which can reduce the length of conventional belt conveying and realize coal supply to multiple compartments.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a coal conveying device capable of supplying multiple separation bins at the same time, including a frame arranged above the multiple separation bins, the frame is arranged along the direction of the separation bin partition, a belt conveyor is arranged on the inner side of the frame, the belt conveyor includes a first roller and a second roller respectively arranged at both ends, a power mechanism is connected to one side of the first roller, and a belt is connected between the first roller and the second roller; tracks are arranged near both sides of the frame surface, a coal conveying trolley that can move freely through the power mechanism is arranged on the track, and the coal conveying trolley is located above the plane where the first roller and the second roller are located, a third roller is arranged near the top at the front end of the coal conveying trolley, and a fourth roller is arranged near the bottom at the rear end, belts are connected between the first roller, the second roller, the third roller and the fourth roller in sequence, and the belt goes from the fourth roller to the first roller to form a complete belt conveyor; the second roller is the feeding end, and the third roller is the discharging end, and a coal separator is arranged near the third roller on the outside of the coal conveying trolley, and the coal separator can ensure that the coal enters both sides of the separation bin partition after being discharged.

[0005] Furthermore, when the coal conveying trolley moves forward and backward, the setting distance between the first roller and the second roller on the frame can realize coal supply to all the compartments.

[0006] The coal distributor is a three-way cavity structure, with an inlet at one end located below the discharge end of the third roller, and outlets at the other two ends respectively located on both sides of the partition plate of the separation bin.

[0007] The power mechanism of the coal conveying trolley is a first motor arranged inside the coal conveying trolley, and a traveling wheel connected to the output end of the first motor through a belt is arranged at the bottom of the coal conveying trolley.

[0008] A second motor is arranged outside the frame, and an output end of the second motor is connected to the first roller through a belt.

[0009] The coal conveying device of the present application has obvious advantages in solving the problem of simultaneous coal supply in multiple compartments. By setting up a rack, a belt conveyor, a coal conveying trolley and a coal distributor, the smooth transportation and uniform distribution of coal are ensured, the problem of the long length of the compartments when placed side by side is solved, and the normal production work during the peak production period is ensured.

[0010] Through the above technical scheme, the coal conveying device provided by the present application can effectively solve the problem of coal supply in multiple compartments at the same time, ensure the smooth transportation and uniform distribution of coal, improve production efficiency, and ensure normal production work during the peak production period. Specifically, the frame is arranged along the partition of the compartment to ensure the stability and reliability of the coal conveying device. The belt conveyor is connected by the first roller and the second roller, and a power mechanism is connected to one side of the first roller to ensure that the belt circulates between the two rollers. A track is arranged on the outside of the frame, and the coal conveying trolley moves freely on the track through the power mechanism to ensure that the coal conveying trolley can move freely between multiple compartments. The coal conveying trolley is located above the plane where the two rollers are located, and a third roller is arranged near the top at the front end of the interior, and a fourth roller is arranged near the bottom at the rear end. The belt connects the first, second, third and fourth rollers to form a complete belt conveyor. The second roller is the feeding end, and the third roller is the discharging end, which ensures the smooth transportation of coal. A coal distributor is arranged near the third roller on the outside of the coal conveying trolley, and the coal distributor can ensure that the coal enters both sides of the partition of the compartment after being discharged, ensuring the uniform distribution of coal.

[0016] Attached Figures 1-3It is an embodiment of the present invention, which discloses a coal conveying device capable of supplying multiple compartments 11 at the same time, including a frame 1, a belt conveyor, a coal conveying trolley 7 and a coal divider 4; the frame 1 is arranged along the partition of the compartment 11 to ensure the stability and reliability of the coal conveying device. A belt conveyor is arranged on the inside, which is connected by a first roller 2 and a second roller 10, and a power mechanism, that is, a second motor, is connected to one side of the first roller 2; a track is arranged on the outside of the frame 1, and the coal conveying trolley 7 moves freely on the track through a first motor 8, ensuring that the coal conveying trolley 7 can move freely between multiple compartments 11, and the coal conveying trolley 7 is located above the plane where the first roller 2 and the second roller 10 are located, and a third roller 5 is arranged near the top at the front end of the interior, and a fourth roller 6 is arranged near the bottom at the rear end, and a belt 9 connects the first roller 2, the second roller 10, the third roller 5 and the fourth roller 6, and finally returns to the first roller 2, forming a complete belt 9 conveying; the second roller 10 is the feeding end, and the third roller 5 is the discharging end, ensuring the smooth transportation of coal. A coal distributor 4 is provided on the outside of the coal conveying trolley 7 near the third roller 5. The coal distributor 4 can ensure that the coal enters both sides of the partition of the separation bin 11 after being discharged, thereby ensuring the uniform distribution of the coal.

[0017] The embodiment of the present invention has obvious advantages in solving the problem of simultaneous coal supply in multiple compartments 11. By setting the frame 1, the belt 9 conveyor, the coal conveyor trolley 7 and the coal distributor 4, the smooth transportation and uniform distribution of the coal are ensured, the problem of the long length of the compartments 11 when placed side by side is solved, and the normal production work during the peak production period is guaranteed.

[0018] The present invention also proposes that when the coal conveying trolley 7 moves forward and backward, the setting distance between the first roller 2 and the second roller 10 on the frame 1 can realize the coal supply to all the compartments 11. By moving the coal conveying trolley 7 forward and backward, the coal supply position can be adjusted, and the distance setting of the first roller 2 and the second roller 10 ensures that all the compartments 11 are covered.

[0019] The setting distance between the first roller 2 and the second roller 10 is designed according to the arrangement length of the partition bins 11, ensuring that the coal transport trolley 7 can cover all the partition bins 11 during the forward and backward movement. Specifically, the distance between the first roller 2 and the second roller 10 should be slightly larger than the total length of the partition bins 11, so that the coal transport trolley 7 can accurately transport the coal into the partition bins 11 at any position. As a preferred embodiment, the distance between the first roller 2 and the second roller 10 can be achieved by adjusting the position of the rollers to accommodate the arrangement of partition bins 11 of different lengths. In addition, the moving speed and position of the coal transport trolley 7 can also be precisely controlled by the power mechanism to ensure the continuity and stability of the coal supply process.

[0020] The present invention solves the problem of coal supply to all compartments 11 by setting the distance between the coal conveying trolley 7 and the first roller 2 and the second roller 10. The coal supply to multiple compartments 11 is realized at the same time, and the coal conveying efficiency is improved; secondly, by adjusting the position of the coal conveying trolley 7, the arrangement of compartments 11 of different lengths can be flexibly handled, and the coal supply has strong adaptability; finally, the coal supply process is continuous and stable, reducing the problem of coal waste and uneven coal supply.

[0021] The coal distributor 4 proposed in the present invention is a three-way cavity structure, one end of the inlet is located below the discharge end of the third roller 5, and the other two ends of the outlet are respectively located on both sides of the partition 11 of the partition. The three-way cavity structure design of the coal distributor 4 can ensure that the coal is evenly distributed to both sides of the partition 11 of the partition at the discharge end. Through such a design, the diversified supply of coal is guaranteed, the needs of different coal qualities are met, and the limitations of the supply of a single coal quality are avoided. The structure of the coal distributor 4 allows the coal to be evenly distributed between the two outlets, thereby improving the efficiency and flexibility of the coal conveying device, and meeting the needs of flexible coal distribution and rapid peak regulation in thermal power plants. Specifically, the three-way cavity structure of the coal distributor 4 can be realized by different designs, for example, a symmetrical three-way structure can be adopted to ensure that the coal can be evenly distributed to the two outlets after entering from the inlet. In addition, a guide plate can be set inside the three-way cavity to optimize the flow path of the coal, reduce resistance, and ensure that the coal is evenly distributed to both sides of the partition 11 of the partition. In addition, the material of the coal distributor 4 can be selected from wear-resistant materials to improve its service life and reliability.

[0022] The power mechanism of the coal conveying trolley 7 is a first motor 8 arranged inside the coal conveying trolley 7. A running wheel 3 connected to the output end of the first motor 8 through a belt 9 is arranged at the bottom of the coal conveying trolley 7 to ensure that the coal conveying trolley 7 runs on the track.

[0023] A second motor is disposed outside the frame 11 , and an output end of the second motor is connected to the first roller 2 through a belt 9 , thereby ensuring the rotating coal conveying function of the first roller 2 , the second roller 10 , the third roller 5 and the fourth roller 6 .

[0024] The above description is only a preferred embodiment of the present invention. The above specific embodiments are not limitations of the present invention. Any modifications, changes or equivalent substitutions made by ordinary technicians in the field based on the above description shall fall within the protection scope of the present invention.
