Description

Technical Field

[0001] The utility model relates to the technical field of pulp refining plates, and in particular to a pulp refining plate capable of improving the refining quality. Background Art

[0002] The pulp grinding disc is the core component of the pulping machine in the pulping section of the papermaking industry. It is a consumable part, and its service life directly affects the quality of pulp, paper quality and production efficiency. Pulp that has been cooked or mechanically ground, screened and bleached cannot be used directly for papermaking. Because the fibers in the pulp lack the necessary flexibility, the bonding force between the fibers is not ideal. If it is used for papermaking, the paper will be loose and porous, with a rough surface and low strength, and cannot meet the requirements of use. The grinding disc is the "heart" of the pulping machine, which directly produces shear, crushing, stretching, friction and other forces on the pulp fibers to change the fiber morphology and meet the adaptability of papermaking.

[0003] After searching, a fan-shaped high-density pulp grinding disc with publication number CN202120961981.1 includes a grinding disc base, the grinding disc base is fan-shaped, a working surface is arranged on the front side of the grinding disc base, grinding teeth are arranged on the working surface, a pulp groove is formed between two adjacent grinding teeth, a base plate is arranged on the rear side of the grinding disc base, an insert block is fixedly connected to the rear side of the grinding disc base, a slot is opened on the front side of the base plate, the insert block is inserted into the slot, a threaded hole is opened on the rear side of the insert block, a mounting hole is opened on the rear side of the slot, and a fastening bolt is installed between the mounting hole and the threaded hole. A fixing hole is provided between the grinding plate base and the grinding tooth, and a through hole is provided on the base plate, and the fixing hole and the through hole correspond to each other in front and back. The pulp grinding plate is composed of the grinding plate base and the base plate. When the working surface on the grinding plate base is excessively worn and the pulp grinding plate needs to be replaced, the base plate can be retained because the grinding plate base and the base plate are detachably connected. Only the grinding plate base needs to be replaced, reducing material consumption and replacement costs. The existing pulp grinding plate is composed of a plurality of sector-shaped grinding plate bases combined into a ring shape, and there is no matching structure between the sector-shaped grinding plate bases, resulting in unreliable matching between the sector-shaped grinding plate bases.
