High consistency hydraulic pulper machine

High consistency hydraulic pulper machine Product Introduction

High consistency hydraulic pulper machine is grind materials designed abroad, mainly used in waste paper deinking process, in high concentration and temperature of 60-90 ℃ rapidly under the condition of waste paper, through the role of chemicals at the same time, make the ink particle and fiber separation, ink particles and impurities as far as possible to keep the original size, so that the back of the ink removal, screening, purification process can go smoothly, using waste paper to produce a high degree of white paste, and save, medicines, and power consumption of steam. High consistency hydraulic pulper has become one of the indispensable core equipment in the process of deinking pulp for waste paper.

High consistency hydraulic pulper machine Structure principle

1. The equipment is of vertical structure, mainly composed of slot, rotor, transmission part, slurry disk, bracket and other parts.

2. The rotor device consists of rotor and bearing device, with a spiral blade on the rotor, the rotor rotates, slurry by the downward movement along the rotor surface, and finally from the lower part of the rotor into tank wall, upward movement along the trench wall again, back to the bottom of the rotor by hydraulic impact and the formation of strong shearing action, paste produced in friction, knead, finally dissociated into single fiber, and interaction of friction between the fiber and the chemistry of deinking agent, the ink from the fiber surface spalling. The bearing supporting device adopts low friction structure, and all non-contact seals except packing cullet, to reduce unnecessary energy loss.

3. The tank is made of welded steel plates with Angle steel flanges on the upper part for the purpose of expanding the volume during high concentration operation and low concentration discharge. The lower part is provided with a groove bottom flange connected with the pulping plate. There are three baffles at the bottom of the tank to promote the backflow of slurry to form a circulation, and the orifice plate is used as a dilution water channel in the case of high concentration fragmentation. The bottom of the tank is provided with a slurry outlet to discharge slurry after the completion of breaking.

4. The lower part of the tank is equipped with a driving part, which is composed of spindle, bearing, bearing seat and belt pulley, etc.

5. Large aperture sieve plate can be installed under the rotor according to process requirements. The replacement of rotor and sieve plate can also be used as a low consistency pulper.

6. The bracket consists of four pipe strings and reinforcing bars to support the tank. The upper part of the reinforcing bar is welded to the tank, and the lower part is welded to the bottom plate, so as to make the support more firm. As a deinking machine, using intermittent operation, according to the process flow, can be high concentration of pulp, can also be low concentration of material.
