Description

Technical Field

[0001] This utility model relates to the field of papermaking and pulping technology, and in particular to a pulp recycling device for papermaking and pulping. Background Technology

[0002] In the papermaking and pulping process, a large amount of waste liquid containing pulp and a large amount of waste pulp containing reusable fibers are generated. If discharged directly, it will not only waste resources but also pollute the environment. Therefore, pulp recycling is a key link in the industry to reduce costs and increase efficiency.

[0003] However, existing devices rely solely on single filtration or simple stirring, which makes it difficult to effectively solve the problems of slurry agglomeration and uneven fiber dispersion. Furthermore, they lack targeted rinsing and residue recovery designs, and slurry easily adheres to the inner wall of the equipment, resulting in waste. They also require many manual assistance steps, leading to low overall efficiency. Utility Model Content
