Abstract

The invention discloses a paper pulp dehydration device including a base; the base is sequentially provided with an accumulation assembly, a shaping assembly and a winding assembly from front to back.The accumulation assembly comprises two sets of supports, and electric lifting bases are arranged on the two sets of supports respectively; a back roller is rotationally arranged between the two setsof electric lifting bases and is driven by a driving motor to rotate; pressing rollers matched with the back roller are rotationally arranged at the front end and the rear end between the two sets ofsupports through sealing bearings. The back roller and the pressing rollers are matched to carry out accumulation dehydration on paper sheets passing between the back roller and the pressing rollers;by means of a suction force of a water suction pump, dehydrated water enters capillary layers of the pressing rollers, passes through a water permeable channel to a hollow shaft and is absorbed by the water suction pump, and secondary damp of paper due to the fact that a large amount of water remains on the pressing rollers is avoided; after accumulation dehydration, paper passes through the shaping assembly, hot air blows to the paper through ventilation holes, and paper drying and rapid shaping are facilitated.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to pulp dewatering equipment. Background technique [0002] Dehydration is an essential process in the paper sheet forming process. Its main function is to remove part of the water in the wet paper sheet and solidify the paper sheet. How to quickly remove the moisture in the wet paper sheet and make it roll properly is the research of dehydration. issues that must be considered and resolved; [0003] Existing dewatering section of paper machine mostly adopts flat press roller to press and dehydrate the paper sheet. Due to the characteristics of flat press roller, water tends to remain on the roller after pressing and then absorbed by the paper sheet, resulting in insufficient dehydration effect and low efficiency. Low, and in the prior art, after dehydration, it cannot be quickly set, and the paper sheet is easily deformed and damaged, and the quality is poor. Therefo...
