Description

Technical Field

[0001] The utility model relates to the technical field of paper pulp production, in particular to a pulping device. Background Art

[0002] Pulp is a necessary raw material for paper production. Usually, pulp production mainly includes two steps: pulping and papermaking. During the pulping process, according to the required paper type and quality requirements, suitable raw materials such as wood, waste paper and crop straw are selected, and the raw materials are pretreated, such as cutting, peeling, crushing, etc., to make them into a form suitable for pulping. The raw materials are heated to a certain temperature to decompose the wood cellulose into fibers and separate the fibers from impurities. This process is divided into two methods: chemical pulping and mechanical pulping. Mechanical pulping is suitable for raw materials with high cellulose content such as waste paper. After pulping, a paste of mixed fibers and impurities is obtained. The fibers and larger impurities need to be separated by screening, and the impurities and the unevenness of the fiber bundles need to be removed by washing. Finally, pure, white pulp is obtained by bleaching.
