Waste paper raw material treatment device and use method thereof

Abstract

The invention provides a waste paper raw material treatment device and a use method thereof. The pulping device comprises an outer shell, a pulping device and a pulping device, the inner shell is rotatably arranged in the outer shell; the circulating flow guide assembly is arranged in the inner shell, the inner space of the circulating flow guide assembly is divided into a first circulating cavity and a second circulating cavity, the second circulating cavity is located in the center of the circulating flow guide assembly, and the first circulating cavity is an annular cavity arranged around the periphery of the second circulating cavity; the air supply assembly can be used for filling bubbles into the circulating flow guide assembly and forming a liquid flow which circularly flows between the first circulating cavity and the second circulating cavity in the circulating flow guide assembly; according to the waste paper raw material treatment device and the use method thereof, adverse effects caused by substances without a regeneration effect, such as plastic films and adhesive tapes, in the waste paper regeneration process can be overcome, and meanwhile, excessive shearing of a pulping device to paper pulp fibers in the waste paper regeneration process is avoided.

Description

technical field [0001] The invention relates to the technical field of packaging paper recycling, in particular to a waste paper raw material processing device and a method for using the same. Background technique [0002] The paper industry is one of the important industries in my country's national economy, but with the increasing shortage of plant resources and people's increasing attention to environmental protection, the recycling of recycled fibers has been highly valued by countries around the world. In my country, regenerated fibers have also become an important part of papermaking raw materials, accounting for more than 1 / 3 of the total papermaking raw materials in my country, and there is a trend of increasing year by year. [0003] Compared with the original plant fiber papermaking process, the papermaking process of waste paper recycling no longer requires peeling, log cutting and crushing, cooking and other processes, so there is no peeling debris, cooking waste...

AI Technical Summary

Problems solved by technology

[0005] First, as a packaging material, the surface of recycled corrugated cardboard is usually glued with a layer of plastic film or some sealing tape remains, but the plastic film and tape do not have the function of regeneration. To completely remove the plastic film and tape when recycling waste paper, often It is necessary to perform cumbersome procedures and pay a lot of labor, which not only increases the difficulty of waste paper recycling, but also increases the cost of waste paper recycling and reduces the efficiency of waste paper recycling; but if the plastic film and tape are not removed, the plastic film Doping with adhesive tape in pulp will not only affect the quality of recycled paper, but also reduce the fluidity of pulp;

[0006] Second, when the waste paper is recycled, since the fibers in the waste paper have been cut to an appropriate degree during the beating process of the base paper, if the pulp fibers are cut again strongly during the beating process of the waste paper regeneration, it will cause the pulp fibers If it is too short, the paper is prone to defects such as reduced strength, reduced folding resistance, and easy fluffing
