Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw coal bunkering technology, specifically to a raw coal bunkering structure that increases peak-shaving flexibility. Background Technology
[0002] Coal bunkers are important facilities in coal mines used for temporary coal storage. They are usually built under production equipment such as coal mining machines or belt conveyors to facilitate the automatic transfer and storage of coal. Coal bunkers can be made of materials such as steel plates and concrete, and are sturdy and durable, with certain stability and special features. Their main function is to store coal, avoid coal waste and return to the mine, and protect coal from moisture, insect infestation, and other factors, ensuring the stability and reliability of coal quality. In addition, coal bunkers also need to have earthquake resistance and fireproof properties to ensure production safety.
[0003] In the existing technology, the raw coal bunker is installed together with the coal-fired power unit. When the coal-fired power unit is under high load or low load, using the same type of raw coal for burning will increase the load pressure on the power system, which may lead to damage to the coal-fired power unit. If the staff needs to adjust the burning raw coal, the coal bunker needs to be replaced and connected to the coal-fired power unit, which is a complicated operation. Utility Model Content
[0004] This invention provides a raw coal bunker compartment structure that increases peak-shaving flexibility and solves the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0006] An embodiment of this utility model provides a raw coal bunker compartment structure that increases peak-shaving flexibility, comprising:

In addition, the surface of the support rod has a chamfered surface, which can prevent coal from accumulating.
[0019] Furthermore, a roller is rotatably connected to the surface of the support rod, and the roller is slidably connected to the inner wall of the rectangular hole.
[0020] The above technical solution, with the roller and support rod working together, can increase the smoothness of movement between rectangular holes.
[0021] Furthermore, the crushing device includes two mounting frames, both of which are fixedly connected to the surface of the coal bunker body. A motor is fixedly connected to the surface of each of the two mounting frames. Two rotating rods are rotatably connected to the inner wall of the coal bunker body. Four crushing plates are fixedly connected to the surface of each of the two rotating rods. Two third hydraulic rods are fixedly connected to the surface of the coal bunker body. The output ends of the two third hydraulic rods are fixedly connected to the rotating rods.
[0022] Through the above technical solution, the combination of the motor and the third hydraulic rod enables the crushing plate to move and rotate back and forth on the inner wall of the coal bunker, so as to come into contact with the clumps of coal and break them up, thereby reducing the blockage inside the coal bunker.
[0023] Furthermore, two extension plates are fixedly connected to both sides of each of the four breaking plates.
[0024] Through the above technical solution, the extension plate can further crush the coal clumps inside during the mixing process.
[0025] Furthermore, each of the four broken plates has two beveled surfaces.
[0026] Through the above technical solution, the inclined plane can guide the movement of the crushing plate, reducing the resistance during the movement.
[0027] The above-described solution of this utility model has at least the following beneficial effects:
[0028] 1. This utility model, by setting an adjustment device, can drive a multi-section rotating plate through a second hydraulic rod to adjust the compartments of the main body of the coal bunker, allowing workers to place high-quality coal and low-quality coal separately.

[0037] like Figures 1 to 4 As shown, an embodiment of this utility model provides a raw coal bunker compartment structure that increases peak-shaving flexibility, comprising:
[0038] The coal bunker body 1; a plow 2, installed on the lower surface of the coal bunker body 1, used to control the opening and closing of the coal bunker body 1; a first hydraulic rod 3, installed on the surface of the plow 2, used to cooperate with the plow 2 to realize the opening and closing of the coal bunker body 1; a vibrator 4, installed on the surface of the coal bunker body 1, used to strike the coal bunker body 1 to achieve a vibration effect; an adjustment device 5 is set on the inner wall of the coal bunker body 1, used to realize the compartment operation of the coal bunker body 1; a crushing device 6, set on the inner wall of the coal bunker body 1, used to crush the raw coal on the inner wall of the coal bunker body 1 to prevent coal clumps from causing blockages.
[0039] like Figures 1 to 3As shown, the adjusting device 5 includes a connecting frame 51, which is fixedly connected to the surface of the coal bunker body 1. Four second hydraulic rods 52 are fixedly connected to the surface of the coal bunker body 1, arranged in pairs. Each pair of second hydraulic rods 52 has a drive rod 53 fixedly connected to its output end. The coal bunker body 1 is rotatably connected to multiple rotating plates 54, which are fixedly connected to the drive rods 53. The second hydraulic rods 52 enable compartmentalized adjustment within the coal bunker body 1, allowing for separate storage of high-quality and low-quality coal, increasing the flexibility of the coal bunker body 1 during use. Anti-sticking plates 55 are fixedly connected to both sides of the multiple rotating plates 54. The anti-sticking plates 55 are made of ultra-high molecular weight polyethylene. The material is made of olefin, which has excellent self-lubricating properties and can effectively prevent coal ore from adhering to the plate. The surface of the multi-section rotating plate 54 is provided with rectangular holes 56. The inner wall of the coal bunker body 1 is fixedly connected to a support rod 57, which is slidably connected to the multi-section rotating plate 54. The surface of the support rod 57 is provided with two chamfered surfaces 58. The support rod 57 can support the other end of the rotating plate when it is divided into compartments, which increases the strength of the multi-section rotating plate 54. In addition, the chamfered surfaces 58 on the surface of the support rod 57 can prevent coal ore from accumulating. The surface of the support rod 57 is rotatably connected to a roller 59, which is slidably connected to the inner wall of the rectangular hole 56. The roller 59 and the support rod 57 cooperate to increase the smoothness of movement between the rectangular holes 56.
[0040] In this embodiment of the utility model (working principle), when the coal-fired mining machine connected to the main body 1 of the coal bunker experiences high or low load, the second hydraulic rod 52 can be activated. The second hydraulic rod 52 can drive the drive rod 53, thereby driving the multi-section rotating plate 54 to adjust the coal bunker. During the adjustment process of the multi-section rotating plate 54, the multi-section rotating plate 54 will move back and forth on the surface of the support rod 57. At the same time, there is a roller 59 on the surface of the support rod 57. The roller 59 can contact the inner wall of the rectangular hole 56 on the multi-section rotating plate 54 to improve the smoothness of the movement of the multi-section rotating plate 54. Furthermore, the support rod 57 can provide further support for the multi-section rotating plate 54 after the coal bunker is adjusted, so that it will not be damaged due to excessive coal accumulation on the surface.

Four crushing plates 64 are fixedly connected to the surface of each rotating rod 63. Two third hydraulic rods 67 are fixedly connected to the surface of the coal bunker body 1, and their output ends are fixedly connected to the rotating rods 63. Through the cooperation of the motors 62 and the third hydraulic rods 67, the crushing plates 64 can move and rotate back and forth on the inner wall of the coal bunker body 1, contacting the clumps of coal and breaking them up, thus reducing blockage inside the coal bunker body 1. Two extension plates 65 are fixedly connected to both sides of the four crushing plates 64, further crushing the coal clumps inside during the mixing process. Two inclined surfaces 66 are formed on the surface of each of the four crushing plates 64, guiding the movement of the crushing plates 64 and reducing resistance during movement.
[0042] In this embodiment of the invention, the starting motor 62 and the third hydraulic rod 67 can drive the rotating rod 63 to rotate, and the crushing plate 64 on its surface will rotate and move back and forth at the same time, which can crush the coal clumps falling from the surface, so that they will not cause blockage when approaching the bin opening. There is an extension plate 65 on the surface of the crushing plate 64, which can contact the coal clumps in the gap between the crushing plates 64, further improving the crushing effect and facilitating their entry into the coal-fired mining machine as fuel.
