Description

Technical Field

[0001] The utility model relates to the technical field of coal conveying and diversion, in particular to a three-way baffle with adjustable diversion mode. Background Art

[0002] The coal conveying system of a thermal power plant, according to design specifications, features two conveyor belts, one in use and one in reserve. This channel switching is achieved at the transfer station. The three-way baffle is a crucial accessory in the coal conveying system, serving as the "hub" connecting the upper and lower conveyors. Its function is to switch the conveying channels of the coal conveying system, ensuring a continuous coal supply.

[0003] The rated output of the coal storage yard conveyor belts in current thermal power plants is far greater than the rated output of the subsequent coal loading belts. Conventional one-to-one operation prevents the coal yard conveyor belts from operating at full capacity, resulting in increased power consumption for coal transportation. Furthermore, given the increasingly complex coal types entering thermal power plants and the inability of coal storage yards to fully blend the coal, the coal conveying system must not only transport the fuel coal but also blend the incoming coal. The existing traditional three-way baffle cannot meet the flexible operation requirements of the existing coal conveying system. Utility Model Content

[0004] To address the shortcomings of existing technologies, the present invention provides a three-way baffle with an adjustable diversion mode. This solves the problem that the rated output of the coal storage yard conveyor belt in a thermal power plant is far greater than the rated output of the subsequent coal loading belt. The conventional one-to-one operation mode causes the coal yard conveyor belt to not operate at full capacity, thereby increasing coal transportation power consumption. Furthermore, considering that the types of coal entering the thermal power plant are becoming increasingly complex and the coal storage yard does not have the conditions for complete blending, the coal conveying system must not only transport the combustion coal but also play a role in blending the coal entering the furnace. The original traditional three-way baffle cannot meet the flexible operation requirements of the existing coal conveying system.

[0005] The utility model provides the following technical solution: a three-way baffle with adjustable diversion mode, comprising a three-way tube body, a baffle center axis fixedly connected between the inner two side walls of the three-way tube body, and both side surfaces of the three-way tube body are fixedly connected to a support frame, and both ends of the baffle center axis extend to the outside of the three-way tube body and are respectively fixedly connected between the two support frames, and two baffle shaft sleeves are rotatably provided on the surface of the baffle center axis, and the upper surfaces of the two baffle shaft sleeves are fixedly connected to the baffle, and the upper surfaces of the two support platforms are fixedly installed with electric push rods, one end of the two baffle shaft sleeves extend to the outside of the three-way tube body and are fixedly sleeved with an electric push rod connecting shaft, and the two electric push rod connecting shafts are movably connected to the output ends of the two electric push rods.

[0006] Preferred technical solution 1: The inner walls of the two discharge ends of the three-way pipe body are fixedly connected with a leak-proof ring.

[0007] Preferred technical solution two: two sets of bearings are fixedly connected to the surface of the baffle center axis, the outer ring surfaces of the two sets of bearings are fixedly connected to the inner walls of the two baffle sleeves respectively, and the two baffle sleeves are rotatably sleeved on the surface of the baffle center axis through the two sets of bearings.

[0008] Preferred technical solution three: the two baffles are close to each other, and the two baffles match the leak-proof ring.

[0009] Preferred technical solution four: The outer surfaces of the two baffles are fixedly covered with a rubber layer, the surfaces of the two rubber layers are provided with an epoxy resin layer, and the surfaces of the two epoxy resin layers are fixedly installed with a plurality of buffer strips.

[0010] Preferred technical solution five: A group of reinforcing rods are fixedly connected between the lower surfaces of the two support platforms and the lower surface of the three-way pipe body respectively.

[0011] Compared with the prior art, the utility model provides a three-way baffle with an adjustable diversion mode, which has the following beneficial effects: when in use, by controlling the extension and contraction of the two electric push rods, the two electric push rod connecting shafts can be driven to rotate, thereby driving the baffle shaft sleeve and the baffle to rotate, so that the position of the baffle can be adjusted according to actual use requirements, so that the material can be discharged from different discharge ports, which is convenient for use. The three-way baffle has a flexible operation mode, which can meet the one-to-one operation mode of the upper and lower material conveying belts, and can also achieve a one-to-two operation mode. For power plants where the coal entering the furnace needs to be blended, the coal storage structure of the coal storage yard can be optimized. The coal entering the furnace can be blended during the transportation process and supplied to two units at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiment 1: A three-way baffle with an adjustable diversion mode comprises a three-way tube body 1, a baffle center axis 2 is fixedly connected between the inner two side walls of the three-way tube body 1, and support frames 3 are fixedly connected to the two side surfaces of the three-way tube body 1, both ends of the baffle center axis 2 extend to the outside of the three-way tube body 1 and are fixedly connected between the two support frames 3, two baffle sleeves 4 are rotatably provided on the surface of the baffle center axis 2, and baffles 5 are fixedly connected to the upper surfaces of the two baffle sleeves 4, support platforms 6 are fixedly connected to the upper surfaces of the two support platforms 6, and electric push rods 7 are fixedly installed, one end of the two baffle sleeves 4 extends to the outside of the three-way tube body 1 and is fixedly sleeved with an electric push rod connecting shaft 8, and the two electric push rod connecting shafts 8 are movably connected to the output ends of the two electric push rods 7 respectively.

[0019] Example 2: The difference between this example and Example 1 is that the inner walls of the two discharge ends of the three-way pipe body 1 are fixedly connected with a leak-proof ring 9, and the leak-proof ring 9 and the baffle can block the material to avoid leakage.

[0020] Example 3: The difference between this example and Example 1 is that two sets of bearings 10 are fixedly connected to the surface of the baffle center shaft 2, and the outer ring surfaces of the two sets of bearings 10 are fixedly connected to the inner walls of the two baffle sleeves 4 respectively. The two baffle sleeves 4 are rotatably sleeved on the surface of the baffle center shaft 2 through the two sets of bearings 10, so that the baffle 5 can be driven by the rotation of the baffle sleeve 4 to block the material, thereby controlling the material to fall from different discharge ports.

[0021] Embodiment 4: The difference between this embodiment and embodiment 1 is that the two baffles 5 are close to each other, and the two baffles 5 match the leak-proof ring 9. The baffles 5 block the material and control the falling position.

[0022] Example 5: The difference between this example and Example 1 is that the outer surfaces of the two baffles 5 are fixedly provided with a rubber layer 11, the surfaces of the two rubber layers 11 are provided with an epoxy resin layer 12, and the surfaces of the two epoxy resin layers 12 are fixedly installed with multiple buffer strips 13, making the baffles 5 more sturdy and durable.

[0023] Example 6: The difference between this example and Example 1 is that a group of reinforcing rods 14 are fixedly connected between the lower surfaces of the two support platforms 6 and the lower surface of the three-way pipe body 1, respectively, to make the support platforms 6 more stable.

[0024] To sum up, when the three-way baffle with adjustable diversion mode is in use, the two electric push rods 7 are controlled to extend and shorten to drive the two electric push rod connecting shafts 8 to rotate, thereby driving the baffle sleeve 4 and the baffle 5 to rotate, so that the position of the baffle can be adjusted according to actual use requirements, so that the material can be discharged from different discharge ports, which is convenient for use. The three-way baffle has a flexible operation mode, which can meet the one-to-one operation mode of the upper and lower material conveying belts, and can also achieve a one-to-two operation mode. For power plants that need to blend the coal entering the furnace, the coal storage structure of the coal storage yard can be optimized. The coal entering the furnace can be blended during the transportation process and supplied to two units at the same time.
