Pulping system for producing paper products by recycling waste paper

Abstract

The invention relates to a pulping system for producing paper products by recycling waste paper. The system comprises a mounting frame, a pulping device, a spraying device, a crushing device and a pushing mechanism, wherein the pulping device is installed at the bottom of the mounting frame, the spraying device is installed on the right side of the top of the mounting frame, a material inlet is formed in the left side of the top of the mounting frame, the pushing mechanism is arranged below the material inlet, the crushing device is installed on the right side of the middle of the mounting frame, a discharging pipe is connected between the pulping device and the crushing device, and the spraying device is located just above the crushing device. The pulping system of the invention can solvethe problems in the treatment after waste paper recovery in the prior art that in a waste paper pulping process, paper pulp is prepared after waste paper is not fully crushed, and the cellulose contained in the paper pulp in the pulping process cannot be fully decomposed when being decomposed again, so that the surface roughness of the produced recycled paper is overlarge, the recycled paper is easy to tear and difficult to form when meeting water so as to reduce the utilization value of the recycled paper..

Description

technical field [0001] The invention relates to the field of recycling and reprocessing of waste paper, in particular to a pulping system for recycling and reusing waste paper to produce paper products. Background technique [0002] Waste paper refers to recyclable renewable resources that are discarded after use in production and life, including various high-grade paper, yellow cardboard, waste cartons, edge-cut paper, packing paper, paper for enterprises and units, engineering paper, books and periodicals Newspapers, etc.; the raw materials of paper are mainly plant fibers such as wood, grass, reed, bamboo, etc. Waste paper is also called "secondary fiber". Give full play to the value of waste paper resources. [0003] At present, there are still the following problems in the treatment of waste paper after recycling: during the pulping process of waste paper, the waste paper is not sufficiently pulverized to make pulp, and the cellulose contained in the pulp cannot be dec...

Problems solved by technology

[0003] At present, there are still the following problems in the treatment of waste paper after recycling: during the pulping process of waste paper, the waste paper is not sufficiently pulverized to make pulp, and the cellulose contained in the pulp cannot be decomposed fully when it is decomposed again during the pulping process. As a result, the surface roughness of the produced recycled paper is too large, it is easy to tear, and it is difficult to form when exposed to water, which reduces the utilization value of recycled paper and loses the original meaning of recycling waste paper for reuse
