Middle high density hydraulic pulper

Abstract

The invention discloses a hydraulic pulp kneader, including the trough solid whose bottom has pulp kneader with corkscrew leaf set vertically, the driving end of pulp kneader is connected to the driving device below the trough solid, and the bottom of trough solid of the pulp kneader driving end is saddlebacked, making the leaf of pulp kneader get away from the bottom of trough solid, avoiding friction between the trough solid and pulp kneader completely, decides the route of whole vorticity circulation and local vorticity circulation formed in the trough solid is lengthed, so that the times of collision is increased and the waste paper is scattered to be the single fiber and it won't be cut off, also, all kinds of nonfiber mixture are kept wholly, it has decreased the energy cost and increased the quality of paper pulp.

Description

technical field [0001] The invention belongs to the field of papermaking machinery, and in particular relates to a medium-high consistency hydraulic pulper. Background technique [0002] There are three principles for the shredding of various waste papers: one is to completely eliminate fiber bundles; the other is not to cut or cut fibers as little as possible; the third is not to destroy or damage various non-fibrous impurities as little as possible. [0003] The bottom of the tank of the existing hydropulper is flat, and the bottom of the rotor of the hydropulper is equipped with a bottom knife. There is a strong mechanical friction between the rotor and the bottom of the tank, and this strong mechanical friction will easily cut the fiber for a while. , reducing the quality of pulp; second, it will destroy various non-fibrous impurities, which will cause difficulties for the subsequent impurity removal process; third, it will cause a substantial increase in power consumpti...

[0003] The bottom of the tank of the existing hydropulper is flat, and the bottom of the rotor of the hydropulper is equipped with a bottom knife. There is a strong mechanical friction between the rotor and the bottom of the tank, and this strong mechanical friction will easily cut the fiber for a while. , which reduces the quality of pulp; second, it will destroy various non-fibrous impurities, which will cause difficulties for the subsequent impurity removal process; third, it will cause a substantial increase in power consumption and increase production costs
