The D-type hydraulic pulpers is mainly used to dismantle various pulp boards, broke paper and various waste papers in the pulping and papermaking process.


The D-series hydraulic pulper is mainly used to dismantle various pulp boards, broke paper and various waste papers.

The D-type hydraulic pulper is designed on the basis of the existing traditional vertical pulper with reference to relevant foreign materials. Its main feature is that the volts rotor is off-center, making the slurry and rotor contact more quickly and at a higher frequency. The traditional hydraulic pulper produces an unobstructed swirl that moves the paper from the point of entry to the center rotor, while the D-type water pulper changes the flow, making the paper faster. Contact with the rotor reduces the time from paper stock to disintegration and increases productivity without increasing power and volume.

D-type hydraulic pulper is generally equipped with a twisting machine and a sediment well. The twisting machine can remove winding impurities, such as plastic bags, rope heads, wire, etc.: The recommended type of twisting machine is ZTS1, the bottom of the tank There is a rectangular interface, the mouth is connected to the sediment well and then the plastic foam and other light impurities are removed by the impurity separator to realize continuous production, and the heavy impurities deposited at the bottom of the sediment well are periodically discharged. The interface can also be used for batch production only with a heavy slag collection tank.


Second, the structural principle / D type hydraulic pulper

The D-type hydraulic pulper is mainly composed of D-shaped tank body, rotor and slurry disc, bracket, motor and protective cover.

When the pulper tank is filled with water 1/2, the motor is started, and the pulp plate, broke or waste paper is evenly put into the tank. When the rotor rotates, the slurry is thrown from the center to the periphery, and a vortex is generated at the center thereof. The material is subjected to strong hydraulic impact and shearing, resulting in fierce friction and softness. At the same time, due to the impact of the rotor, the pulp plate and the damaged paper are disintegrated in a wet state, dissociated into a single fiber, and separated and separated. The slurry flows out through the sieve hole, and the foreign matter and heavy slag are collected and discharged regularly in the sediment tank; during continuous operation, the foreign matter and the heavy slag enter the sediment well, and the impurities are discharged after being processed by the impurity separator. Due to the special structure of the series of hydraulic pulper tanks, when the rotor rotates, the slurry flow is blocked by the D-shaped straight face of the tank to the center, which shortens the rotary path of the slurry, and the slurry is disintegrated more frequently. The undisassembled paper sheets and fiber bundles are further decomposed in the gap between the rotor and the screen. Due to the special shape of the tail of the blade, it has the function of keeping the mesh hole from being blocked. When the waste paper is dismantled, the rope machine is equipped to continuously remove the winding impurities, which can greatly extend the continuous running time of the pulper and improve the working efficiency.

1. D-shaped tank body:

It is welded by steel plate, the outer part of the upper part is reinforced with channel steel, and the baffle is placed inside the conical bottom to make the slurry flow back to form a circulation. The bottom of the tank has a rectangular interface that is connected to the sediment well, which is opened on site by the user according to the process requirements.

2. Rotor device:

Including rotor, sieve plate, pulping disc and transmission. The rotor is a Volx energy-saving rotor made of cast steel. The blade is made of tool steel and heat treated. The blade is fastened to the rotor blade with screws and can be replaced after wear. The sieve plate is made of wear-resistant stainless steel, and the bottom knife is set on the bottom. The gap between the bottom surface of the rotor blade and the bottom plate of the sieve plate is initially set to 2 mm, and can be adjusted by adjusting bolts as needed.

The rotor and the slurry disc are higher than the bottom of the tank. On the one hand, a low pressure zone is formed around the slurry disc to collect impurities, impurities are carried into the sediment well by the slurry flow, and continuously separated; on the other hand, the contact of the impurities with the rotor can be reduced. Extend the service life of the rotor and prevent the strand from being wound around the rotor for proper operation. There is a good pulp outlet pipe under the pulping tray, which can be connected with the slurry pump.

3. bracket:

Welded from steel plates to support the tank and rotor assembly.
