Working Principle of Wet Broke Pulper

The working principle of wet loss pulper mainly relies on the force of water flow and mechanical agitation of the dual role of the waste paper raw materials for crushing, dispersion and wetting treatment.

Wet paper pulper is one of the key equipments in the paper industry, its working principle is delicate and efficient. During the pulping process, bundles of waste paper, which may contain different types of paper, impurities or even small amounts of metal fragments, are fed into the inlet of the hydro pulper. As the machine starts, a powerful stream of water is sprayed into the pulper from the bottom or side, creating a high-speed vortex. This vortex not only has a huge impact force, which can instantly break up the waste paper mass, but also has excellent penetration ability, which penetrates deep into the waste paper fibers and promotes the separation of the fibers.

At the same time, the hydro pulper is equipped with special blades or rotors inside, and these rotating parts are driven by the motor to rotate at a certain speed to further physically crush the waste paper. The design of the blades often takes into account the optimal combination of shear force and impact force, which can effectively cut off the long fiber bundles in the waste paper, but also avoid over-crushing resulting in fiber damage and affecting the quality of the pulp. In order to accelerate the removal of ink, adhesive and other impurities in the waste paper, the pulping process will also be added to the appropriate amount of chemicals, such as deinking agent.

These chemicals, assisted by the water flow, can be more fully in contact with the waste paper to improve the deinking efficiency. Over time, the waste paper is gradually broken down into a mixture of fine fibers and water, i.e., preliminary pulp. Finally, the fully broken down and deinked pulp through the screen or centrifugal equipment to further remove the residual large particles of impurities, to obtain a more pure pulp. This process not only improves pulp utilization, but also provides high-quality raw materials for subsequent papermaking processes.

Failure of reading part: Replace the deformation of pointer, scale wear, paint peeling, blurring and other problems on the reading part to ensure normal display and accurate reading.

What should be paid attention to when using wet broke pulperr?

Inspection before starting: The operator should carefully check whether all parts of the equipment are intact and undamaged, especially the key parts such as rotor, stator and screen, to make sure that there is no blockage, wear and tear or loosening phenomenon. At the same time, check whether the electrical system, lubrication system and water supply are normal to ensure that the equipment is started in the best condition.

Gradually increase the load: In the start-up process, the water flow and speed should be gradually increased to avoid the impact of instantaneous high load operation on the equipment. At the same time, monitor the instrumentation to ensure that the parameters fluctuate within the preset range, in order to ensure the efficiency and stability of crushing.

Reasonable control of feeding amount: According to the type of raw materials, moisture content and target pulp quality, reasonably control the feeding amount, crushing time and hydraulic impact strength. By adjusting the water inlet valve and rotating speed, the raw materials can be fully broken under the action of hydraulic force to achieve the ideal state of fiber dispersion.

Slag removal and cleaning: After the completion of crushing, use the slag removal system of the hydraulic pulper to remove the un-crushed impurities and coarse fibers to keep the system clean. Subsequently, the equipment is fully cleaned to prevent residues from affecting subsequent production.

Routine inspection and maintenance: After completing the cleaning, close all the valves and power supply, and carry out routine inspection and maintenance of the hydro pulper, such as replacing worn parts, replenishing lubricating oil, etc., so as to be ready for the next use.

Safe operation: During operation, avoid bringing your fingers or other body parts close to the rotating parts, especially on machines without safety sensors, you must be more careful and keep your attention to avoid injury.

Regular cleaning: The confetti box must be emptied in time when it is full to prevent overfilling leading to paper jam or affecting the performance of the machine. After a long period of work, the machine should be allowed to rest properly to avoid overheating.

Pay attention to maintenance and renewal: Regular lubrication of the shredder is the key to keep it in good working condition. Use specialized lubricants and follow the manufacturer's instructions for maintenance. Considering the continuous updating of technology and features, choose the right model of shredder for different office needs and security requirements.
