Abstract

The invention relates to a grinding plate unit of an grinding plate of a pulping machine, the grinding plate unit is a fan-shaped sheet and is provided with an inlet end and an outlet end, grinding teeth are arranged on a bottom plate of the grinding plate unit, tooth grooves are formed between every two adjacent grinding teeth, and in the circumferential direction of the grinding plate unit, thegroove width of a first tooth groove located in the middle of the grinding plate unit is larger than the groove width of second tooth grooves located in the two ends of the grinding plate unit. The tooth height of the first grinding teeth located in the middle of the grinding plate unit is larger than the tooth height widths of second grinding teeth located at the two ends of the grinding plate unit. The tooth widths of the grinding teeth on the whole grinding sheet unit are the same; and the grinding teeth are arc-shaped in the depth direction. Compared with the prior art, the grinding plateunit has the advantages of high beating degree and the like.

Description

technical field [0001] The present invention relates to a papermaking refiner plate for processing material containing wood fibers, in particular to a refiner plate refiner unit. Background technique [0002] Materials containing wood fibers or similar fibers are the main raw materials for papermaking and pulping. After some preparatory treatment in the early stage, the fibers are decomposed, cut, separated, and broomed with a refiner to make pulp that meets different requirements, and then make paper or for other purposes. The refiner is the main equipment in papermaking pulping, and the refining plate in the refiner is the core component that affects the quality and output of refining. The grinding disc is composed of a whole or a group of separate grinding units. There are many different structural forms such as disc grinding discs, conical grinding discs, cylindrical grinding discs, etc., but they are all composed of one or a group of grinding discs. Or two or two grou...
