By unscrewing the pressure cap from the positioning screw, the filter cartridges can be quickly removed from the upper discs, allowing for rapid cleaning of the residue in the filter cartridges and facilitating subsequent slag removal of the pulp.

Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and more specifically, to a papermaking machine slag removal device. Background Technology

[0002] With the improvement of people's living standards and the rapid development of new energy sources, the demand for paperboard is increasing. However, the pulp used in paperboard production often contains a large amount of residue, such as plastics, sand, iron, asphalt, paraffin wax, ink, and adhesives. These residues significantly affect the quality of the paperboard. Existing paper machine descrambling devices typically pour the pulp directly into a screen bin for filtration using a vibrating screen. However, vibrating screens are noisy and prone to clogging, leading to pulp overflow. Furthermore, cleaning a clogged screen is inconvenient; brushing is difficult and inefficient. Disassembling the screen for cleaning is complex and difficult. Additionally, opening and closing the descrambling bin lid during pulp filtration is difficult, hindering the rapid addition of pulp.
