The coal loading and coke pushing operations of the top-loaded coke oven are relatively frequent. Under the condition of unchanged total coke output, reducing coal loading and coke pushing operations and reducing the number of unorganized emissions in the coke oven area is beneficial to improving the environment in the coke oven area and increasing the stacking density of the coal charged to the oven. Under the premise of equal coke quality, it is beneficial to reduce the coal blending cost and increase benefits.
[0031] Based on this, the embodiment of the present disclosure provides a device for increasing the bulk density of coal loading, including a roller, a driving mechanism and a supporting mechanism, wherein the roller is arranged above the conveying belt of the furnace coal belt conveyor, and the supporting mechanism is arranged below the conveying belt, the driving mechanism is connected to the roller, and the driving mechanism is used to drive the roller to rotate along the conveying direction of the conveying belt, the roller and the supporting mechanism are arranged relative to each other, and a conveying passage is formed between the roller and the supporting mechanism. By implementing the technical solution of the present disclosure, the coal loading and pushing operations can be reduced, the number of unorganized emissions can be reduced, and the coal loading can be compacted, thereby increasing the bulk density of coal loading, thereby increasing the output of a single-hole coke oven, and under the premise of the same coke quality, it is beneficial to reduce the coal blending cost and increase the efficiency.
[0032] The device for increasing the density of coal loading is described in detail below through specific embodiments:
[0033] Reference Figures 1 to 4 As shown, in the first aspect of the present disclosure, there is provided a device for increasing the density of coal loading, including a roller 1, a driving mechanism 2 and a supporting mechanism 3, the roller 1 being arranged above the conveying belt 100 of the furnace coal belt conveyor, the supporting mechanism 3 being arranged below the conveying belt 100, the driving mechanism 2 being connected to the roller 1, and the driving mechanism 2 being used to drive the roller 1 to rotate along the conveying direction of the conveying belt 100, the roller 1 and the supporting mechanism 3 being arranged opposite to each other, and a conveying passage 200 is formed between the roller 1 and the supporting mechanism 3.
[0034] A conveying passage 200 is formed between the roller 1 and the supporting mechanism 3 of the present invention. The material passes through the conveying passage 200 formed by the two before being transported to the coke oven. In the conveying passage 200, the cooperation between the roller 1 and the supporting mechanism 3 can compact the coal charged into the coke oven, thereby reducing the coal loading and coke pushing operations and the number of unorganized emissions while keeping the total coke output unchanged, thereby increasing the coal loading pile density and improving the output of a single-hole coke oven. Under the premise of the same coke quality, it is beneficial to reduce the coal blending cost and increase the efficiency.
