Problems solved by technology

[0002] Existing papermaking uses wood flour, which is supplied by the wood flour manufacturer as finished wood flour, which is mixed with wood flour and water through the preparation tank, and directly sent to the paper machine for pulping through the feeding pump; this requires high quality wood flour, and other sundries The content is less than 5%, and the fineness and particle diameter of wood flour are less than 0.15mm. After adding this kind of wood flour, the binding force between fibers and fibers is reduced, and the cost of wood flour is high

Embodiment 1

[0032] Such as figure 1 Shown, the invention discloses a kind of preparation technology of wood powder for papermaking, comprises the following steps:

[0033] The first step, the preparation of finished wood flour slurry, select 40-80 mesh wood flour, put 5 parts by mass of wood flour into the preparation tank, add 95 parts by mass of clear water, stir and soak for 20 minutes, and prepare finished wood flour slurry. The wood powder is prepared from coniferous trees and / or broad-leaved trees; the stirring is performed by a hydraulic pulper built in the preparation tank; the wood powder is automatically transported to the preparation tank by a chain plate machine.

[0034] The second step, filter and remove slag, control the mass concentration of the wood powder slurry obtained in the first step to be 3-5%, and transport it to the slag remover by the first pulp pump to filter and remove slag, and obtain the wood powder after removing impurities pulp.

[0035]The third step is...

Abstract

The invention discloses a reparation process and a treatment system for papermaking wood flour. The preparation process comprises processes of preparing of log slurry, filtering for slag removal, untwining and devillicate, screening and layered output. The treatment system comprises a preparation tank, a slag remover, a deflaker, a first slurry pool, a UV flow rising pressurized screen and a second slurry pool. The reparation process and a treatment system for the papermaking wood flour have the advantages of being high in quality consistency and binding force between fibers, low in cost and green and environmentally friendly in process.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a preparation process and a processing system of wood powder for papermaking. Background technique [0002] Existing papermaking uses wood flour, which is supplied by the wood flour manufacturer as finished wood flour, which is mixed with wood flour and water through the preparation tank, and directly sent to the paper machine for pulping through the feeding pump; this requires high quality wood flour, and other sundries The content is less than 5%, and the fineness and particle diameter of wood flour are less than 0.15mm. After this kind of wood flour is added, the binding force between fibers and fibers is reduced, and the cost of wood flour is high. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process and treatment system of wood powder for papermaking, which has the characteristics of high quality consistency, stron...
