Description
Continuous high concentration HydrapulperTechnology
The invention belongs to the field of papermaking machinery, in particular to a high concentration pulper.
BACKGROUND
The role pulper paper fibers are separated and formed of the same fibers in water homogeneous suspension. Hydraulic pulper in the tank by adding a device to form a pulp paper. Low consistency pulper, the percentage of water contained in the paper can be between 1-6%, while high consistency pulper, the amount of water contained in the paper are available from 12% to 18%.
High consistency pulper specific role stains diffuse and continuous mixing of the paper through the rotor, the rotor having a plurality of vanes, are coiled into a spiral along the longitudinal axis of the rotor. Pulp through the spiral formed by the blade transport passage in the end portion, and then rose to the top from the bottom up in order to then run down, and so back and forth several times through said rotor.
Prior art vertical high concentration Hydrapulper pided and without sieve sieve with two, without the sieve can be used only intermittently pulper, which is in the pulping process pulp does not emit , after pulping to a slurry, because if the continuous pulping cause large piece of paper is not fluffed discharge equipment, such pulper at the initial stage of pulping because a lot of friction between paper collisions, shredding efficiency is higher, as the process for shredding, less paper, shredding efficiency is greatly reduced, since frequent turning on the motor stops, so that the energy consumption of pulping greatly increased.
