Problems solved by technology

[0003] In the above process steps, conveying the washed pulp to the subsequent steps requires the use of a conveying screw. However, because the pulp is seriously agglomerated after pulp washing, simply conveying the lumpy pulp will greatly reduce the efficiency of the subsequent steps. ; Therefore, for the particularity of straw production slurry, the traditional conveying screw is difficult to meet the requirements

Abstract

The invention relates to a dilution device for straw papermaking slurry. The dilution device comprises a dilution trough, wherein a feeding hole is formed in the top of the dilution trough, a discharging hole is formed in the bottom of the dilution trough, a rotating shaft is mounted at a transverse middle axis in the dilution trough, first driving equipment is arranged at one end of the rotatingshaft, the rotating shaft is surrounded by spiral blades, and a plurality of water nozzles are formed in the upper part of the dilution trough; a feeding trough body is mounted on the feeding hole andcomprises an upper-layer crushing trough and a lower-layer filtering trough, a crushing roll with crushing teeth is transversely arranged in the crushing trough, one end of the crushing roll is connected to second driving equipment, and a discharging hole communicated with the filtering trough is formed in the bottom of the crushing trough; and the filtering trough is used for filtering crushed slurry in a screen net filtration manner. The dilution device can meet the requirements on the conveying of the straw papermaking slurry, the agglomeration of the slurry can be reduced, the dilution can be realized, and the dilution uniformity is high.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a dilution device for straw papermaking slurry. Background technique [0002] Wood is generally used as the main raw material in the papermaking industry, but with the further deterioration of the environment, this process of using logs as raw materials is gradually being replaced. In order to meet the needs of the papermaking industry to the greatest extent, the use of fur , Cotton stalks, reeds, corn stalks, straw and other grasses as raw materials for pulping not only provide a new source of fiber for the paper industry, but also realize the utilization of waste, changing the original above-mentioned materials that can only be incinerated or recycled. In the case of Tiantian, the comprehensive utilization of resources has been realized, which has excellent social and economic benefits. In the process of processing raw materials, the above-mentioned raw materials...
