Hydraulic pulper is one of the most commonly used pulping equipment in the pulp and paper industry. It mainly disintegrates pulp boards, used books, used cardboard boxes, etc. From the structural form, it can be divided into a vertical hydraulic pulper and a horizontal hydraulic pulper.


Vertical hydraulic pulper: The main structure has a trough body, the rotor (impeller), the bottom knife ring and the motor, etc. The general speed of the turntable is km/min, and the diameter of the trough is 1-6m. The current capacity of the hydraulic pulper in China is 1-30 cubic meters. Models.


Working principle: start the motor, the impeller starts to rotate, the slurry in the tank body is sucked along the center of the axis, and is thrown out from the circumference at high speed, forming a severe turbulent circulation due to the tearing of the impeller blades and the mutual turbulence of the slurry layers at different speeds. A huge frictional effect is generated, the slurry is strongly decomposed in the wet state, and the fibers are separated, and the fiber bundle rubs against each other in the gap between the impeller and the sieve plate to increase the effect of fibrosis.


Horizontal hydraulic pulper: It is divided into two types: volt (horizontal) hydraulic pulper and drum type (drum type) hydraulic pulper.


The volt-type hydraulic pulper has a side-mounted rotor with an impurity collector in the lower part of the tank. The other structure is the same as that of the vertical pulper. This pulper is capable of handling unsorted waste paper.


The drum type hydraulic pulper can continuously remove non-fibrous impurities which are difficult to disintegrate, and has a large production capacity. It uses the partition of the inner wall of the cylinder to continuously carry the paper material, and at a certain height, it is dropped to the bottom of the cylinder, and the purpose of dissociating the fiber is achieved by tearing and shearing. Major impurities are not damaged by mechanical damage and are more easily removed by decontamination equipment.
