Novel household paper pulp preparing device and technology

Abstract

The invention discloses a novel household paper pulp preparing device and a novel household paper pulp preparing technology. Compared with the conventional pulp preparing device, the novel household paper pulp preparing device has the advantage as follows: staple fiber is treated through disc mills instead of a defibering machine; compared with the conventional technology, the novel household paper pulp preparing technology has the advantages as follows: in the whole process, one defibering machine, two beating towers, two pulp preparing tanks and corresponding four pulp pumps are reduced; a static mixer is used, and except for a mixed pulp, chemicals added from the tops of the conventional pulp preparing tanks are mixed more uniformly, so that the retention rate of the chemicals can be increased. The novel household paper pulp preparing device is simple in structure, reduces use of equipment, shortens the whole pulp preparing process, lowers the energy consumption, reduces the equipment, reduces use of workshops, and can adjust the technical system more quickly. By the novel household paper pulp preparing technology, an unnecessary temporary pulp storage point is omitted, the temporary storage time is shortened, a pulp preparing system is shortened, and repeated pumping and stirring of the pulp are reduced so as to achieve the purpose of lowering the energy consumption; meanwhile, the fixed investment can also be reduced.

Description

technical field [0001] The invention belongs to the technical field of household paper processing, and in particular relates to a novel household paper pulp preparation device and a pulp preparation process. Background technique [0002] High-grade household paper is growing rapidly in my country's household paper market, and it is also a daily consumer product that is becoming more and more popular in national consumption. However, the production cost of domestic high-grade household paper remains high, especially the cost of energy. The traditional pulp preparation process is as follows: long-fiber wood pulp and short-fiber wood pulp are pulped separately, the pulp concentration is 5-6%, and the disintegration time is 8 minutes, and then pumped into the unloading tower. After a short period of storage, they are respectively pumped into The deflagging machine and disc refiner enter the knocking tower, and enter the blanket layer and net layer pulping tank for pulp mixing. ...

AI Technical Summary

Problems solved by technology

This kind of process is relatively complex and long, with many control points, resulting in increased power consumption, large building area, and high cost. According to estimates, the power consumption of the pulp preparation section of the tissue machine accounts for about 30% of the entire papermaking process, and the total retention of pulp The time is 124 to 409 minutes, which takes a long time, and more equipment is used, which consumes a lot of energy
