Description

Technical Field

[0001] The utility model relates to the technical field of slag discharge in paper production, in particular to an automatic cleaning slag discharge filtering device. Background Art

[0002] The slag filter device in the papermaking process is a key device for removing impurities and undissolved fiber bundles from the pulp and ensuring the quality of paper. The slag filter device usually works based on the screening principle, using screens or filters with different apertures to separate solid particles and fibers in the pulp. When the pulp passes through the filter device, larger impurities and fiber bundles are retained by the screen, while finer fibers and liquids flow out through the screen, thereby purifying the pulp. The existing slag filter structure requires manual cleaning of the slag body and filter components after use, which is time-consuming and labor-intensive and has poor practicality.
