[0002] Sugarcane is a major byproduct of sugar refineries, and its waste is enormous. As a major sugarcane producer, my country produces a considerable amount of bagasse annually, providing a sufficient source of raw material for pulping and papermaking. Bagasse fibers are of moderate length, easy to boil and bleach, require minimal chemicals, and have a superior fiber morphology compared to some grass-based fiber raw materials, making it an ideal material for papermaking. However, existing bagasse pulping and papermaking filtration devices often experience bagasse residue accumulation during filtration, hindering subsequent filtration and reducing papermaking efficiency. Furthermore, the filter screen cannot be disassembled, making it difficult for workers to clean the filter screen. Utility Model Content
