Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to a high-efficiency pulper for papermaking. Background Art

[0002] In the papermaking industry, pulpers are mainly used to break down various cardboards, damaged paper and waste paper. They can be divided into vertical hydraulic pulpers and horizontal hydraulic pulpers in terms of structure. They are mainly used to break down pulp boards, waste books, waste cartons, etc. At present, in the field of papermaking, as people pay more and more attention to environmental protection and plant raw materials for papermaking are becoming increasingly scarce, the proportion of waste paper used in pulping and papermaking is increasing. In the actual use of pulpers in the prior art, waste paper is usually put into the equipment. The paper is mixed with water and soaked under the drive of the rotor, and is quickly torn to form pulp. However, some paper will form small clumps during the rotation process, resulting in a longer soaking time, and it is not easy to be decomposed into pulp, resulting in a longer pulping time, which will affect the efficiency and power consumption of the device.

[0003] Therefore, a high efficiency pulper for papermaking is proposed. Utility Model Content
