Description

Technical Field

[0001] The utility model relates to the technical field of papermaking processing devices, and belongs to a waste paper fiber high recovery rate pulping device. Background Art

[0002] Waste paper recycling aims to reduce environmental pollution and achieve resource recycling. By collecting, sorting and processing waste paper, waste paper recycling converts it into reusable pulp or paper products, which not only saves precious forest resources but also reduces the cost of the paper industry. This action is of great significance to promoting sustainable development.

[0003] Waste paper recycling pulping equipment is mainly based on the reuse of waste paper fibers. The equipment first crushes, shreds or cuts the waste paper into smaller pieces. Subsequently, these pieces are further refined into pulp through specific mechanical actions such as stirring, friction and impact. During the pulping process, impurities such as plastics and metals in the waste paper will be removed by corresponding impurity removal devices to ensure the purity of the pulp.

[0004] The current waste paper recycling pulping device does not crush the waste paper sufficiently during use, which affects the efficiency of waste paper recycling. In addition, when the waste paper is pulped, other impurities are mixed in it, which affects the purity of the pulp, which will cause the final quality of the pulp to deteriorate.
