Series type D waterpower pulp machine is mainly used for OCC, intermittent or continuous pulp products such as waste paper, sedimentation in the heavy impurities in a separate waste emissions, prevent damage of equipment by heavy metal, plastic and can be ruled out. The d-type series hydraulic pulping machine is based on the existing traditional vertical shredder based on the foreign information design. Its main characteristic is: vex rotor deviation center position, make the pulp and rotor contact more quickly, more frequency. Traditional waterpower pulp machine to produce a rotary flow unimpeded, paper material from join according to spiral line to the center of the rotor in sports, and type D hydrapulper has changed the way of the flow, make the paper material more quickly in contact with the rotor, which can shorten the paper into pulp material handling time, and without any increase in power and volume under the condition of increasing production capacity. Type D series waterpower pulp machine is equipped with a general twisted rope machine and sediment well, twisted rope machine can remove tangling impurities, such as plastic bags, rope, wire, recommend to the twisted rope of maxhine ZTS1, tub at the bottom of a rectangle interface, the pick up sediment Wells by impurity separator to remove the plastic foam and other impurities, realize the continuous production, sediment at the bottom of the well sedimentary heavy impurities regularly. The interface can also be used only for batch production 2. Structure principle D type hydraulic shredder is mainly composed of D type tank, rotor and pulping disk, bracket, motor and protective cover. Pulper tank affusion 1/2 solutions, start the motor, pulp board, damaged paper or paper evenly into the tub, the rotor rotates, slurry from the center to throw around, in its at the center of the vortex, slurry by the strong hydraulic shock and shearing action, produce intense friction and gentle rub each other, at the same time due to the effect of impact of the rotor to make pulp board, damage of paper under the wet pulp, dissociated into single fiber, separation by organization of the pulp flow through the screen mesh, foreign body, heavy slag collection in sediment tank regularly; In continuous operation, the foreign body and heavy slag enter the sediment well, and the impurities are treated by the impurities separator. Because of the special structure, the series of waterpower pulp machine tub when the rotor rotation, slurry flow by the tub D shape face block bends to the center, shortened the slurry return path, pulp by beating frequency is higher. Unbroken pieces of paper and fiber bundles are further unsolved in the gap between the rotor and the screen. Because of the special shape of the tail of the blade, it has the function of keeping the mesh not blocked. It can greatly prolong the continuous running time and improve the working efficiency.
