The pulper manufacturer analyzes the working principle of the pulper and the type of pulper
- 2018-07-05-

      Hydraulic Pulper<> is one of the most commonly used pulping equipment in the pulp and paper industry, mainly disintegrating 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 tank body, a rotor (impeller), a bottom knife ring and a motor. Generally, the peripheral speed of the turntable is 1000 m/min, and the diameter of the trough is 1-6 m. At present, the capacity of hydraulic pulper in China is 1-30 cubic meters. Working principle: The motor is started, the impeller starts to rotate, the slurry in the tank body is sucked along the center of the axis, and is thrown at a high speed from the circumference to form 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, which causes the slurry to strongly disintegrate and separate the fibers in the wet state, and the fiber bundles are in the gap between the impeller and the sieve plates. Rubbing against each other increases 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 hydropulper has a side-mounted rotor with an impurity collector at the bottom of the tank, and the other structure is the same as that of the vertical pulper. This pulper is capable of handling unsorted waste paper.
      The drum type hydropulper can continuously remove non-fibrous impurities that 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 machinery and are more easily removed by decontamination equipment.
