The hydraulic pulper is one of the core equipment in pulp and paper laboratories, mainly used for efficient dissociation, crushing, de ink removal, and fiber dispersion of primary pulp and recycled pulp. In the laboratory environment, it undertakes the key task of processing pulp boards, damaged paper, and various waste paper samples. It is not only an important tool for evaluating the performance of recycled pulp processes, the applicability of additives, and pulp quality, but also provides a reliable experimental platform for the research and optimization of papermaking chemical additives.

1、In terms of function, the device drives the turntable and blades to rotate at high speed inside the material cylinder through a motor, enabling the separation of fibers in the slurry water mixture under the dual action of mechanical shear and fluid friction. The uniquely designed wedge-shaped turbulence plate further enhances the turbulence effect of the internal fluid, improves the friction and tearing efficiency between fibers, and completes the uniform disintegration of the slurry in a short period of time, truly simulating the pulping process in industrial production. Whether it is the initial dispersion of high concentration native pulp or the de ink fragmentation of waste paper containing impurities, this equipment can stably and reliably complete experimental tasks, laying the foundation for subsequent pulp evaluation, screening, bleaching and other process research.

2、In terms of structural characteristics, the hydraulic pulper embodies a high combination of humanized design and practical technology. The equipment adopts a combination of manual speed regulation and mechanical speed regulation, with high torque output and adaptability to different slurry characteristics and process requirements. The speed can be adjusted within200-3000r/mFlexible adjustment within the scope. The digital control system displays the rotor speed, slurry temperature, and heating time in real time, combined with a fully automatic time and temperature control module, to achieve visualization and precise management of the experimental process. The sealing structure adopts technology to solve the common problem of rotor leakage in traditional equipment, ensuring stable and clean long-term operation.

3、The whole machine adopts0Cr18Ni9Made of stainless steel, the slurry tank is equipped with a stainless steel sealing cover with a visible window, combined with a spiral fastening structure, which not only ensures operational safety but also facilitates observation of the internal slurry state. The bottom valve is designed with a straight discharge and integrated frame structure, making slurry discharge and cleaning more convenient, meeting the requirements of efficient and clean laboratory work. Its compact appearance（1100mm×750mm×1300mm）With reasonable weight（80Kg）Balancing equipment stability and laboratory space utilization efficiency.

Overall, hydraulic pulpers have become one of the equipment in pulp and paper laboratories due to their reliable crushing performance, flexible parameter adjustment, complete automation control, and stable structural design. It not only improves the accuracy and reproducibility of experimental data, but also provides strong technical support for researchers to conduct research on slurry characteristics, process optimization, and new product development.
