High consistency deinking hydrapulper for waste / white shavings paper pulping to make toilet paper

High consistency hydraulic pulper is used for high concentration crushing of waste paper.

Vertical high-concentration hydraulic pulper is mainly composed of tank body, impeller, rotor, sieve plate, column and so on. Its main disintegrating structure is impeller and rotor. When the impeller and the rotor rotate, the high-concentration pulp moves radially. the two spiral blades on the rotor rotate at the same time, and it is turned axially from the side of the tank. The material is in a high-concentration state in the tank. Through the axial and radial movement of the impeller and the two helical blades, the fibers rub against each other to separate the ink particles from the fibers. In addition, due to the weaker shear points of the rotor and spiral blades, it only peels off the light substances (such as plastic films) in the waste paper, and does not form debris, which facilitates the screening of pulp.

High concentration hydraulic pulper is one of the indispensable equipment in the deinking and pulping process of waste paper. During the working process of this equipment, the waste paper is always in a high-concentration state (the pulp concentration is generally maintained between 10-16%). Under the mechanical force, it produces strong land and the friction between the paper materials. Cooperating with various chemical additives (such as deinking agent, tablet alkali, sodium silicate, hydrogen peroxide, surfactant, etc.) and condensed water (temperature: 60-97Co) discharged from the dryer of the paper machine, the auxiliary heating effect makes the ink It can be separated from the paper sheet, and if necessary, can be heated by steam to achieve the effect of removing ink. Under the effect of temperature and softening of chemical additives, the disintegration speed of the paper material is accelerated, the damage to the paper fibers due to the strong disintegration is reduced, and the fiber length and flexibility are guaranteed. Saves pulping time and improves efficiency

Specification:

ADVANTAGE:

1. High-concentration pulper rotor has high pulp concentration (about 3 percentage points higher than that of traditional high-concentration pulper); the treatment of waste paper deinking pulp can greatly reduce the energy consumption of pulp heating and chemical Consumption and strong degreasing effect, promote the ink particles to peel and disperse faster from the fiber; and it has almost no cutting effect on single fiber; and has less damage to impurities.

2. The discharging and diluting device can directly discharge the high-concentration slurry without diluting it in the pulper barrel, which greatly shortens the discharging time of the high-concentration slurry, reduces the power of the equipment, and saves power consumption. It is particularly suitable for the subsequent process. Demand for high consistency slurry.
