Description

Technical Field

[0001] The present invention relates to the technical field of coal mine transportation, and particularly to a coal yard coal conveying channel device with an anti-blocking function. Background Art

[0002] A coal yard refers to a place for stacking coal, usually an auxiliary facility of a coal-fired power plant or a steel plant. With the continuous improvement of China's coal production capacity, the continuous strictness of national environmental protection policies, and the continuous enhancement of people's environmental protection awareness, the previous commonly used open-air coal storage method by coal production enterprises no longer meets the requirements. A fully enclosed coal storage yard that meets the actual needs of the enterprise must be adopted to ensure good economic, environmental, and social benefits for the enterprise. In coal transportation, pipeline coal transportation is a new transportation method, mainly applied to industrial transportation.

[0003] Currently, in the pipeline transportation of coal, due to the constant size of the pipeline, if the coal flow rate is large, blockage will occur. Most devices will relieve the pipeline pressure by adjusting the angle of the pipeline to increase the coal transportation speed. However, this will cause the amount of coal transported to the combustion equipment to increase rapidly, resulting in incomplete combustion of coal and waste of resources, and making the transportation effect of the pipeline poor. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a coal yard coal conveying channel device with an anti-blocking function, which solves the problem of incomplete combustion of coal caused by the rapid increase in the amount of coal transported to the combustion equipment.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A coal yard coal conveying channel device with an anti-blocking function, including a support platform, on which a support plate is rotatably installed. On one side of the support plate, a first U-shaped plate is slidably installed, and on the other side of the support plate, a second U-shaped plate slidably connected to the first U-shaped plate is slidably installed;

[0007] An expansion device for adjusting the size of the channel is installed on the support plate;

[0008] A vibration device for preventing coal from sticking to the inner wall of the pipeline is installed on the support plate;

[0009] An adjusting device is installed on the support platform. With the start of the adjusting device, the support plate drives the first U-shaped plate and the second U-shaped plate to rotate, and the distance between the first U-shaped plate and the second U-shaped plate increases.

[0010] Preferably, the expansion device includes two groups of limiting grooves formed on the support plate. Two fixing columns are fixedly installed on each group of limiting grooves. A limiting block slidably connected to the fixing columns is slidably installed on each group of limiting grooves. A fixing plate is fixedly installed on the limiting block. A support column is fixedly installed between the two fixing plates. Two connecting plates respectively rotatably connected to the first U-shaped plate and the second U-shaped plate are rotatably installed on the fixing plate.

[0011] Preferably, the expansion device further includes two groups of first sliding plates fixedly installed on the support plate. First sliding grooves slidably connected to the first sliding plates are formed on both the first U-shaped plate and the second U-shaped plate. A plurality of fixing rods slidably connected to the first sliding plates are evenly installed on the first sliding grooves.

[0012] Preferably, the expansion device further includes second sliding plates fixedly installed on the first U-shaped plate and the second U-shaped plate. Second sliding grooves slidably connected to the second sliding plates are formed on both the first U-shaped plate and the second U-shaped plate.

[0013] Preferably, the vibration device includes a toothed plate fixedly installed on the first U-shaped plate and the second U-shaped plate. A blanking plate is fixedly installed on the support plate. Two grooves are formed on the blanking plate. A gear meshing with the toothed plate is rotatably installed on each group of grooves.

[0016] Preferably, a discharge plate is fixedly installed on the support plate. First baffles are fixedly installed on both the first U-shaped plate and the second U-shaped plate. Second baffles are fixedly installed on both the first U-shaped plate and the second U-shaped plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the setting of the expansion device of the present invention, by starting the electric telescopic rod, the first U-shaped plate and the second U-shaped plate move outward, so that the cross-sectional area of the coal conveying channel is enlarged, more coal can be transported, and the blockage of the coal conveying channel can be effectively avoided. Moreover, the inclination angle of the coal conveying pipeline is reduced, avoiding the situation that the amount of coal transported to the combustion equipment increases rapidly, resulting in incomplete combustion of the coal.

[0019] 2. By setting the vibration device, the vibration motor contacts the bottom of the blanking plate through the movement of the first U-shaped plate and the second U-shaped plate. The magnetic adsorption interfaces on the limiting plate and the blanking plate are attracted to each other. When the coal blocks fall onto the blanking plate, the vibrating blanking plate can break up the caked coal formed due to moisture or particle adhesion, avoiding the situation of blockage at the feeding port caused by the accumulation of coal at the feeding port.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will describe in detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0028] Embodiment 1

[0029] Since the size of the pipeline remains unchanged, if coal clogs occur under a large flow rate, most devices will relieve the pipeline pressure by adjusting the angle of the pipeline to increase the coal transportation speed. However, this will cause the amount of coal transported to the combustion device to increase rapidly, resulting in insufficient coal combustion and waste of resources. To solve this problem, referring to Figures 1 - 5 , this embodiment proposes a coal yard coal transportation channel device with an anti-blocking function, including a support platform 1. A support plate 11 is rotatably installed on the support platform 1. A first U-shaped plate 12 is slidably installed on one side of the support plate 11. A second U-shaped plate 13 that is slidably connected to the first U-shaped plate 12 is slidably installed on the other side of the support plate 11. A discharge plate 5 is fixedly installed on the support plate 11. First baffles 501 are fixedly installed on both the first U-shaped plate 12 and the second U-shaped plate 13. Second baffles 502 are fixedly installed on both the first U-shaped plate 12 and the second U-shaped plate 13. The first baffles 501 and the second baffles 502 are provided to prevent coal from overflowing;

[0030] An expansion device 2 for adjusting the size of the channel is installed on the support plate 11. A vibration device 3 for preventing coal from sticking to the inner wall of the pipeline is installed on the support plate 11. An adjustment device 4 is installed on the support platform 1. With the activation of the adjustment device 4, the support plate 11 drives the first U-shaped plate 12 and the second U-shaped plate 13 to rotate, and the distance between the first U-shaped plate 12 and the second U-shaped plate 13 is increased, so that the cross-sectional area of the channel is increased, avoiding coal blockage in the channel.

[0031] The expansion device 2 includes two groups of limit slots 201 formed in the support plate 11. Two groups of fixed columns 202 are fixedly installed on each group of limit slots 201. A limit block 203 slidably connected to the fixed column 202 is slidably installed on each group of limit slots 201. The fixed column 202 makes the movement of the limit block 203 more stable. A fixed plate 204 is fixedly installed on the limit block 203. A support column 205 is fixedly installed between the two fixed plates 204. Two connecting plates 206 respectively rotatably connected to the first U-shaped plate 12 and the second U-shaped plate 13 are rotatably installed on the fixed plate 204. The expansion device 2 further includes two groups of first sliding plates 207 fixedly installed on the support plate 11. First sliding slots 208 slidably connected to the first sliding plates 207 are formed in both the first U-shaped plate 12 and the second U-shaped plate 13. A plurality of fixed rods 209 slidably connected to the first sliding plates 207 are evenly installed on the first sliding slots 208, making the movement of the first U-shaped plate 12 and the second U-shaped plate 13 more stable. The expansion device 2 further includes second sliding plates 210 fixedly installed on the first U-shaped plate 12 and the second U-shaped plate 13. Second sliding slots 210 slidably connected to the second sliding plates 210 are formed in both the first U-shaped plate 12 and the second U-shaped plate 13. The adjusting device 4 includes an electric telescopic rod 401 fixedly installed on the support platform 1. A connecting block 402 rotatably connected to the fixed plate 204 is fixedly installed at the movable end of the electric telescopic rod 401. When the coal transportation volume increases, the electric telescopic rod 401 is started to drive the connecting block 402 to move downward, so that rotation occurs between the connecting block 402 and the fixed plate 204 and the limit block 203 connected to the fixed plate 204 moves in the limit slot 201. Under the action of the support column 205, the movement of the fixed plate 204 can drive the movement of the other fixed plate 204. Under the action of the connecting plate 206, the movement of the fixed plate 204 drives the first U-shaped plate 12 and the second U-shaped plate 13 to move outward, so that the cross-sectional area of the coal conveying channel is enlarged, more coal mines can be transported and the blockage of the coal conveying channel can be effectively avoided, and the inclination angle of the coal conveying pipeline is reduced, avoiding the situation that the amount of coal transported to the combustion equipment increases rapidly, resulting in incomplete combustion of the coal.

[0032] Embodiment 2

[0033] If the humidity in the coal yard is relatively high, the coal will stick together due to moisture and form larger coal lumps. If the caked coal is relatively large, it may block the feeding port. To solve this problem, refer to Figures 1 - 5, the vibration device 3 includes a toothed plate 301 fixedly installed on the first U-shaped plate 12 and the second U-shaped plate 13. A blanking plate 302 is fixedly installed on the support plate 11. Two groups of grooves 303 are formed on the blanking plate 302. A gear 304 meshing with the toothed plate 301 is rotatably installed on each group of grooves 303. A threaded rod 305 rotatably connected to the blanking plate 302 is fixedly installed on the gear 304. The vibration device 3 further includes a limiting plate 306 threadedly connected to the threaded rod 305. A vibration motor 307 is fixedly installed on the limiting plate 306. Magnetic attraction interfaces 308 that attract each other are fixedly installed on both the limiting plate 306 and the blanking plate 302. The vibration motor 307 is started by the attraction contact of the two groups of magnetic attraction interfaces 308. When the first U-shaped plate 12 and the second U-shaped plate 13 move outward, the movement of the first U-shaped plate 12 and the second U-shaped plate 13 drives the toothed plate 301 to move, causing the threaded rod 305 connected to the gear 304 to rotate within the limiting plate 306, causing the limiting plate 306 to move upward. The movement of the limiting plate 306 drives the vibration motor 307 and the two groups of magnetic attraction interfaces 308 on the limiting plate 306 to move, and makes the vibration motor 307 contact the bottom of the blanking plate 302. The magnetic attraction interface 308 on the limiting plate 306 attracts the magnetic attraction interface 308 on the blanking plate 302. When the coal block falls onto the blanking plate 302, the vibrating blanking plate 302 can break up the caked coal formed due to moisture or particle adhesion, avoiding the situation of blockage at the feeding port caused by the accumulation of coal at the feeding port.

[0034] Working principle: Start the electric telescopic rod 401 to drive the connecting block 402 to move downward, causing rotation between the connecting block 402 and the fixing plate 204 and driving the limiting block 203 connected to the fixing plate 204 to move within the limiting groove 201. Under the action of the support column 205, the movement of the fixing plate 204 can drive the movement of another group of fixing plates 204. Under the action of the connecting plate 206, the movement of the fixing plate 204 drives the first U-shaped plate 12 and the second U-shaped plate 13 to move outward, expanding the cross-sectional area of the coal conveying channel. When the first U-shaped plate 12 and the second U-shaped plate 13 move outward, the movement of the first U-shaped plate 12 and the second U-shaped plate 13 drives the toothed plate 301 to move, causing the threaded rod 305 connected to the gear 304 to rotate within the limiting plate 306, causing the limiting plate 306 to move upward. The movement of the limiting plate 306 drives the vibration motor 307 and the two groups of magnetic attraction interfaces 308 on the limiting plate 306 to move, and makes the vibration motor 307 contact the bottom of the blanking plate 302. The magnetic attraction interface 308 on the limiting plate 306 attracts the magnetic attraction interface 308 on the blanking plate 302. When the coal block falls onto the blanking plate 302, the vibrating blanking plate 302 can break up the caked coal formed due to moisture or particle adhesion.
