The invention relates to the technical field of
papermaking, in particular to a lignified
cellulose pulp forming device based on
solid-liquid separation. The paper pulp conveying device comprises a conveying belt, the conveying belt is used for conveying paper pulp, protection plates are installed on the two sides of the conveying belt, limiting rods are fixedly installed on the side faces, close to the conveying belt, of the protection plates, a
grinding roller is arranged at the top of the conveying belt, an
extrusion roller is installed in the conveying belt, and the
extrusion roller is installed below the
grinding roller. The
extrusion roller and the rolling roller are used for
rolling paper pulp conveyed by the conveying belt, a driving
assembly is installed on one side of the rolling roller and one side of the extrusion roller, the driving
assembly is used for driving the rolling roller and the extrusion roller to rotate, a leveling plate is arranged on the side, close to the conveying belt, of the protection plate, and the leveling plate is arranged above the conveying belt. Paper pulp is conveyed on the conveying belt, and the height is leveled through the leveling plate, so that the paper pulp is conveniently and quickly rolled by the rolling roller and the extrusion roller for
solid-liquid separation.
