Coke cutting roller

Abstract

The invention discloses a coke cutting roller which comprises a roller shaft, a plurality of pull rods, a roller shaft sleeve arranged on the roller shaft through an end sleeve, a plurality of gear rings arranged on the roller shaft sleeve, spacer rings arranged between the adjacent gear rings, and end discs arranged at the two ends. Roller shaft sleeve through holes are formed in the middles of the end discs, the middles of the spacer rings and the middles of the gear rings. The end discs, the spacer rings and the gear rings are arranged on the roller shaft sleeve through the roller shaft sleeve through holes in a penetrating and sleeving manner. Pull rod through holes are formed in the outer rings of the roller shaft sleeve through holes of the end discs, the spacer rings and the gear rings. The pull rods penetrate into the end disc on one side, penetrate the gear rings and the spacer rings arranged on the roller shaft sleeve in sequence, penetrate out of the end disc on the other side, and are in fastened connection through pull rod nuts. Each gear ring comprises a disc-shaped gear ring disc body and a plurality of main cutter teeth evenly distributed on the outer periphery of the gear ring disc body. An inwards concave chip groove is formed between every two adjacent main cutter teeth. Slope faces are formed on three sides of the main side face of each main cutter tooth, and the contact position of every two adjacent slope faces is of a corner angle structure. The coke cutting roller achieves point contact coke cutting.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a coke cutting roller. Background technique [0002] At present, commercially available coke is a large block structure with irregular shapes and sizes, which cannot be directly used in industrial production. In the process of industrial production, lump coke needs to be further pulverized and processed into coke raw materials with a certain particle size to meet the needs of industrial equipment, such as metallurgical equipment. [0003] The wolf tooth crusher is a kind of coke crushing equipment, but it has the technical problems of high powder extraction rate and easy damage to the equipment itself. Aiming at the above-mentioned problems of the wolf-tooth crusher, a coke cutter adopts a toothed cutter clamped on the roller shaft, and the roller shaft drives the cutter to rotate to realize the cutting of coke lumps. For example, the Chinese patent document whose pu...

Problems solved by technology

[0004] The toothed roller of the above-mentioned coke cutting machine, that is, the rolling shaft with the gear ring, the cutting blade on the gear ring, that is, the knife teeth, is in surface contact with the material when cutting the coke, and the cutting resistance is relatively large. The cutting blade wears quickly, and the cutting blade often breaks. After cutting, the coke material is often jammed between two adjacent cutting blades, which affects the cutting efficiency and cutting quality of coke.
