Description

Technical Field

[0001] The utility model belongs to the technical field of vertical mill equipment for post-processing of calcined coke, in particular to a vertical mill for post-processing of calcined coke. Background Art

[0002] Calcined coke: In the production of graphite electrodes for steelmaking or anode paste (melting electrode) for aluminum and magnesium, the carbon raw materials must be calcined to make them meet the requirements. The calcination temperature is generally around 1300°C, with the purpose of removing the volatile matter in the carbon raw materials as much as possible. This can reduce the hydrogen content of the carbon raw material re-products, increase the graphitization degree of the carbon raw materials, thereby improving the high temperature strength and heat resistance of the graphite electrode, and improving the conductivity of the graphite electrode. Calcined coke is mainly used to produce graphite electrodes, carbon paste products, corundum, food-grade phosphorus industry, metallurgical industry and calcium carbide, among which graphite electrodes are the most widely used. Calcined coke is a black or dark gray hard solid petroleum product with a metallic luster and is porous. It is a carbonaceous substance composed of tiny graphite crystals in granular, columnar or needle-shaped forms. The components of calcined coke are hydrocarbons, containing 90-97% carbon, 1.5-8% hydrogen, and also nitrogen, chlorine, sulfur and heavy metal compounds. The production process of calcined petroleum coke powder is completed in four steps, including crushing, grinding, grading, powder collection and packaging. Each step is closely connected. During the use of the existing vertical mill for calcined coke post-processing, a lot of noise will be generated due to vibration when grinding the material, and it will damage the ground.

[0003] For example, the invention with the announcement number CN111468242A discloses a vertical mill for post-processing of calcined coke. The technical solution of this patent includes a frame, a shell, a motor, a reducer, a separator, a grinding disc, a grinding roller and a feed hopper. The frame is provided with an air compressor. A block is rotatably installed on the top of the grinding disc. The block is a conical cavity structure. Two or more telescopic rods are fixed in the inner cavity of the block at equal distances along its rotating axis. The telescopic rod is a cavity structure. The air compressor is connected to the inner cavity of the telescopic rod through an air pipe. The air compressor is used to drive the telescopic rod to extend and retract. The telescopic rod passes through the block. A shift block is fixed at one end of the telescopic rod located outside the block. During the use of this device, a large amount of noise will be generated due to vibration when grinding the material, and the ground will be damaged. Therefore, a vertical mill for post-processing of calcined coke is proposed. Utility Model Content
