Description

Technical Field

[0001] The utility model relates to the technical field of paper cup base paper production, in particular to a pulp processing device for paper cup base paper production. Background Art

[0002] Paper cups are a kind of paper container made by mechanically processing and bonding base paper made of chemical wood pulp. It has a cup-shaped appearance. In the production of base paper for paper cups, in order to save resources, waste paper needs to be collected and recycled first. It can be recycled through recycling stations, recycling vehicles, etc. The recycled waste paper needs to be classified and processed, and different types of waste paper are separated for subsequent recycling. The recycled waste paper will be sent to the paper mill for pulping. The waste paper is soaked in water and heated. Usually, a stirring device is required to continuously stir the slurry to make the pulp stir evenly, separate the fibers and form slurry. Generally, the fine fibers in the pulp can reduce the thickness, bulk and air permeability of the paper, and can significantly improve the tensile strength of the paper. The stirred slurry is filtered through a screen and then flows into the receiving device for collection and utilization. The collected pulp will be sent to the paper machine for papermaking production, and recycled paper is formed through processes such as calendering and drying. Recycled paper can be used to make paper cup base paper and other products, and processed into finished paper cups.
