Description

Technical Field

[0001] The invention relates to the technical field of waste paper regeneration, and in particular to a waste paper regeneration pulping device and a pulping method thereof based on a composite sensing technology. Background Art

[0002] As a rich and renewable fiber resource, the recycling of waste paper is of great significance for saving wood, reducing energy consumption and reducing pollution. In the waste paper recycling process, hydraulic pulper is a widely used traditional pulping equipment. It mainly uses the hydraulic shear force generated by the high-speed rotating impeller and the strong turbulent water flow to tear and break the waste paper in the water, thereby achieving the initial dissociation of fibers.

[0003] However, due to the limitations of actual production conditions, small waste paper recycling plants in rural areas often mix heavy residues into the waste paper they use for production. The current hydraulic pulpers are unable to filter out the larger and heavier residues in the waste paper, resulting in more heavy residues mixed into the pulp obtained after pulping, affecting subsequent processes. In addition, traditional pulping equipment lacks accurate process monitoring and control methods, and operators can only roughly judge the pulping process based on experience, which increases labor costs.
