A kind of pulp mixing process technology

Abstract

The invention relates to the field of papermaking, in particular to a pulp blending process technology. A pulp blending process technology includes the following steps: in the first step, long fiber material enters a pulper for pulping, and then the long fiber is output to the long fiber Discharge tower, which outputs the lost pulp of the paper machine to the short fiber discharge tower; in the second step, the long fibers stay in the long fiber discharge tower and then enter the first refiner and the second refiner in turn, and then output to the felt respectively. Layer mixing pool, mesh layer mixing pool; in the third step, the short fibers enter the fourth refiner after staying in the short fiber discharge tower, and output to the blanket layer mixing pool and the mesh layer mixing pool; the fourth step, After mixing short fibers and long fibers, the felt layer mixing tank is output to the third refiner, and then output to the felt layer paper machine pulp tank, and then enters the de-felt layer flushing pump, and then output; the fifth step, the mesh layer matching After mixing short fibers and long fibers, the pulp chest is output to the pulp chamber of the wire paper machine, and then enters the de-wire layer flushing pump, and then output. It solves the problem of excessive energy consumption in the pulp blending process.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a pulp blending process technology. Background technique [0002] At present, high-end 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 energy cost. In order to reduce the energy consumption of high-end household paper products, we have established a project to develop a short-process process for the pulp preparation workshop of high-end household paper, shortening the process links and reducing the energy consumption in the production process. [0003] The main feature of the short-flow process is that it shortens the papermaking process, reduces the residence and swelling time of fibers in the system, and has potential adverse effects on quality indicators suc...
