Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and more specifically, to a pulp filtration device for waste paper recycling. Background Technology

[0002] Papermaking using waste paper is an environmentally friendly recycling process. The main steps include waste paper recycling, sorting, shredding, removal of impurities (such as plastics and adhesives), and deinking. Subsequently, bleaching (optional) restores fiber cleanliness, forming recycled pulp, which is then processed into new paper products through papermaking, pressing, and drying. This process significantly reduces wood consumption and energy use, lowers wastewater and carbon emissions, and gives waste paper a second life. It is widely used in the production of packaging paper, newsprint, and sanitary paper, representing an important practice for achieving efficient resource utilization and sustainable development.

[0003] Pulp made from waste paper usually contains small particulate impurities, so it needs to be filtered during the papermaking process. Most existing methods use filter screens directly for filtration, but the viscous pulp can easily accumulate on the screens, affecting the filtration speed and even causing the screens to become clogged, resulting in poor filtration efficiency.
