A pulp refiner for papermaking

Abstract

The invention relates to the field of paperboard manufacturing device and particularly relates to a pulping machine for papermaking, which comprises an overhaul board, a guiding structure, a grindingstructure, a water inlet valve, a feeding structure, a shell, a driving structure and an anti-blocking structure. The driving structure used for driving is arranged on the bottom of the shell; the driving structure is connected to the grinding structure which is arranged in the shell and used for grinding; the guiding structure used for flow guiding is arranged at the bottom end of the grinding structure; the anti-blocking structure used for feeding is arranged in the grinding structure; the anti-blocking structure is connected to the feeding structure which is arranged on the shell and used for storing material. The anti-blocking structure of the pulping machine for papermaking is connected to the grinding structure, which effectively prevents the internal blockage of the grinding structure, and makes the grinding structure grind paper raw materials evenly, thereby greatly improving the grinding quality. The feeding structure is connected to the grinding structure, which makes the feeding structure convenient to control the uniform velocity of material entering the inner grinding structure, and effectively prevents the clogging of materials in the feeding structure, thereby improving feeding quality, and making the feeding speed of raw materials adjustable.

Description

technical field [0001] The invention relates to the field of cardboard manufacturing equipment, in particular to a refiner for papermaking and pulping. Background technique [0002] Cardboard, also known as cardboard, is a thick paper sheet made of various pulps and interwoven fibers. Cardboard is widely used in article packaging, which can effectively prevent damage to packaged articles and make transportation more convenient. In the process of cardboard manufacturing Raw materials need to be ground by a refiner, which refers to a machine that grinds processed raw materials into a slurry. [0003] However, when the traditional paper pulping refiner grinds raw materials, it is easy to cause the internal blockage of the equipment and the blockage of the lower hopper, thereby affecting the grinding quality, and the pulp is inconvenient to store. In view of this, the invention provides a kind of refiner for papermaking pulping, which has the following characteristics: [0004...
