D type hrdrapulper for paper pulp making

Structure

• D-type Tank: The D-shaped tank of the D-type Hydrapulper is made of welded steel plates. This unique shape is designed to change the form of the vortex in the pulping process, which is beneficial for the uniform distribution of the pulp and the improvement of the pulping effect.
• Rotor Assembly: The rotor device is located above the bottom plane of the pulper tank. When it rotates at a high speed, it can form a low-pressure flow area around it, which is convenient for collecting heavy impurities and facilitating the separation of impurities from the pulp.
• Drive Mechanism: It usually consists of a motor, a speed reducer and a coupling. The drive mechanism transmits the power of the motor to the rotor accurately, enabling the rotor to rotate at an appropriate speed and providing the necessary power for the pulping process.
• Deflector: The deflector is located at the bottom of the inner cone. Its function is to guide the pulp to flow back and form a circulation, which can enhance the mixing and pulping effect of the pulp and improve the quality and efficiency of pulping.

Working Principle

• Turbulence Intensification: The D-type Hydrapulper changes the way of pulp flow. When the rotor rotates, it generates a strong turbulent flow in the tank. This turbulent flow can quickly immerse the paper bales below the liquid level and increase the contact frequency between the waste paper and the rotor, thus accelerating the separation of fibers.
• Low-pressure Area Formation: Due to the fact that the rotor and the pulp outlet plate are higher than the bottom plane of the tank, a low-pressure area is formed around the rotor. Under the action of pressure difference, coarse impurities will flow to the heavy slag outlet, realizing the automatic removal of impurities.
• Hydraulic Circulation: The special design of the D-type Hydrapulper enhances the hydraulic circulation in the tank. The circulating water flow continuously impacts and shears the fibrous materials, which is conducive to the dissociation of fibers and makes the pulp more uniform.

Performance Characteristics

• Energy-saving: Compared with traditional hydrapulpers, the D-type Hydrapulper adopts advanced design and technology, which can effectively reduce energy consumption and save production costs.
• High Efficiency: It can significantly shorten the pulping time and improve the production capacity per unit volume. The efficient pulping effect can increase the production efficiency and meet the needs of large-scale production.
• Long Service Life: The unique structure of the D-type Hydrapulper reduces the contact between impurities and cutters or screens, which can effectively prolong the service life of the rotor, cutters and screens, reducing equipment maintenance and replacement costs.
• Automatic Impurity Removal: It has the function of automatically discharging coarse and winding impurities, which can effectively remove various impurities in the waste paper and improve the quality of the pulp.
• Easy to Operate: The D-type Hydrapulper is equipped with an intelligent control system, which makes the operation simple and convenient. Operators can easily adjust operation parameters such as rotor speed and pulp concentration through the control panel.

Application Areas

• Waste Paper Recycling: It is widely used in the waste paper recycling industry and is suitable for the pulping of various waste papers, such as OCC (Old Corrugated Containers) and commercial waste paper. It can effectively recycle waste paper resources and turn them into high-quality pulp.
• Pulp and Paper Industry: In the pulp and paper industry, the D-type Hydrapulper is used for the pulping and purification of pulp boards, damaged paper and waste paper. It is an important equipment in the pulping process and provides high-quality raw materials for paper production.
