Abstract

The invention provides powdering and then grinding type pulping equipment. The equipment mainly comprises a conical feeding inlet device, a rectangular tooth-shaped roller device, a stirring device, aconical grinding roller device, a bevel gear drive device and an inclined filter device. The equipment is characterized in that paper sheets are smashed and recycled through rectangular tooth-shapedrollers, and then slurry grinding is performed through a conical grinding roller. The recycled paper sheets are smashed in advance through shear force formed by the rectangular tooth-shaped roller device; the paper sheets and liquid water are stirred through rotation of the stirring device, and feed liquid soaking stirring and accelerated downward flowing are achieved; slurry is ground through thehigh-speed rotating conical grinding roller, and fine grinding of the paper sheets is achieved; due to rotation of the inclined filter device, liquid water and slurry separation is achieved.

Description

technical field [0001] The present invention relates to a pulverizing first and then grinding type pulping equipment, in particular to a kind of pre-crushing of recycled paper through the shearing force formed by a rectangular toothed roller device, and realizes the material liquid by stirring the paper and liquid water through the rotation of the stirring device. The immersion stirring and accelerated downward flow, the fine grinding of the paper is realized through the high-speed rotating conical grinding roller grinding slurry, and the separation of liquid water and slurry is realized through the rotation of the inclined filter device, which belongs to the technical research and development field of pulping equipment in the paper industry . Background technique [0002] In the paper industry, the production of recycled pulp requires putting pulp boards, waste books, waste cartons, etc. into a hydropulper, and crushing them through the rotation of the rotor to make a unifo...
