Technical Field

[0001] The utility model relates to the field of pulp preparation, in particular to a core pulp improved sorting device. Background Art

[0002] Core pulp refers to the pulp used to produce paper and cardboard, which is usually made from raw materials such as wood pulp and waste paper pulp. In the pulp preparation process, the pulp obtained after pulping, bleaching and other treatments is called core pulp. Core pulp is an important raw material in paper production. Its quality and performance directly affect the quality of the final paper. There may be various impurities in the core pulp, such as sawdust, stones and metals, which will affect the quality and appearance of the paper.

[0003] The existing improved core pulp sorting is to first pour the core pulp onto a screen, screen and separate the core pulp from impurities through the screen, and then manually pour the screened core pulp into a container filled with bleach and clean water to bleach the core pulp to remove lignin and other colored substances in the core pulp. Since the core pulp processing steps need to be performed separately and manual operation is time-consuming and labor-intensive, it affects the pulp preparation efficiency and is relatively inconvenient.

[0004] Therefore, it is necessary to design an improved core pulp sorting equipment that can automatically perform vibration screening on the core pulp and automatically perform stirring and bleaching on the core pulp to achieve integrated operation, save manpower, and improve pulp preparation efficiency.
