Problems solved by technology

[0003] In the thickening step, generally an ordinary tank body is used, and a stirring device is installed in the tank body. The traditionally used stirring device is a propeller stirring shaft. However, for a slurry substance with a high concentration, the resistance is too large, and it cannot be stirred well. cause uneven mixing

Abstract

The invention relates to a concentration tank for straw papermaking. The concentration tank comprises a cylindrical tank body, wherein a round partition board is arranged in the middle of a cavity body of the tank body to divide the tank body into an upper-layer first tank body and a lower-layer second tank body, an unloading hole is formed in the partition board, and an openable-closable baffle cover is arranged on the unloading hole; a first rotating shaft is arranged at a central axis of the first tank body, the top end of the first rotating shaft is connected to driving equipment, and thefirst rotating shaft is surrounded by a spiral stirring component; and a second rotating shaft is arranged at a central axis of the second tank body, the top end of the second rotating shaft is connected to the bottom end of the first rotating shaft, the second rotating shaft is surrounded by a spiral stirring component, and a discharging hole is formed in the central position of the bottom of thesecond tank body. The concentration tank is high in stirring efficiency and uniformity and can effectively meet the concentration requirements in straw papermaking.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a thickening tank for straw papermaking. 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 need t...
