The Hydraulic Pulper is a key equipment in the pulp and paper manufacturing industry, designed for the efficient breakdown of waste paper, pulp boards, and other raw materials into a fibrous suspension.

 

 

Mainly used for pluling of virgin pulp and other clean raw materriral with mid consistency.

 

Different rotors can be used for different furnish processing.

 

 

The Hydraulic Pulper works by placing the raw materials such as waste paper and pulp boards into the pulper tank and adding an appropriate amount of water and chemical agents. Driven by an electric motor, the impeller rotates at a high speed, exerting strong shearing, frictional, and hydraulic impact forces on the materials. These forces rapidly break down the materials into a fibrous suspension.

 

 

1. Tank: Holds the raw materials, water, and chemical agents during the pulping process.
2. Impeller: The main working component that generates the mechanical forces for breaking down the raw materials.
3. Motor: Provides the power to drive the impeller rotation.
4. Inlet and Outlet: The inlet is for feeding the raw materials and water into the tank, while the outlet is for discharging the pulped fibrous suspension.

 

 

1 Installation

• Choose a stable and level foundation to install the Hydraulic Pulper.
• Connect the pulper to the power supply and ensure the electrical connections are secure and in accordance with local electrical codes.
• Install the inlet and outlet pipes to ensure a smooth flow of materials and pulped suspension.

 

2 Commissioning

• Before commissioning, check all components and connections to ensure they are properly installed and tightened.
• Fill the tank with a small amount of water and run the impeller at a low speed to check for any abnormal noises or vibrations.
• Gradually increase the speed and add the raw materials and water in the prescribed quantities to test the pulping performance and ensure the equipment is operating within the specified parameters.

 

 

1 Startup

• Check that the tank is clean and free of any debris or foreign objects.
• Open the inlet valve and fill the tank with water up to the required level.
• Start the motor and gradually increase the rotational speed to the desired setting.
• Feed the raw materials into the tank gradually while maintaining the water level and rotational speed.

 

2 Operation

• During operation, monitor the pulping process closely to ensure the quality and consistency of the fibrous suspension.
• Adjust the rotational speed, feed rate, and water addition as needed to optimize the pulping performance.
• Periodically check the temperature and vibration of the motor and other components to ensure their normal operation.

 

3 Shutdown

• Stop feeding the raw materials and allow the impeller to continue running for a few minutes to clear the remaining materials in the tank.
• Stop the motor and close the inlet and outlet valves.
• Drain the remaining water and pulped suspension from the tank and clean the tank and components thoroughly.

 

 

In the vast landscape of the pulp and paper industry, the Hydraulic Pulper stands as a remarkable innovation that has transformed the way we process raw materials. This essential equipment has become the backbone of pulp production, facilitating the efficient breakdown of waste paper and other fibrous materials into a homogeneous suspension.

 

The Hydraulic Pulper works on the principle of hydrodynamic forces. It combines mechanical action with the flow of water to disintegrate the raw materials. The process begins when the waste paper or other fibrous substances are introduced into the large, cylindrical tank of the pulper. As the pulper starts to operate, a high-speed rotor or impeller, located within the tank, begins to rotate. This rotation generates a powerful vortex and turbulence within the water-filled tank.

 

The raw materials are drawn into this turbulent flow, where they undergo intense mechanical forces. The impact, shear, and rubbing actions between the materials and the rotor, as well as the surrounding tank walls, cause the fibers to separate from each other and from any impurities or contaminants. The result is a suspension of individual fibers in water, ready for further processing in the papermaking process.

 

The Hydraulic Pulper offers several advantages that make it indispensable in the industry. Its high efficiency allows for a rapid pulping process, reducing production time and increasing output. It also demonstrates a remarkable ability to handle a wide variety of raw materials, from different types of waste paper to various grades of pulp boards.

 

Moreover, the Hydraulic Pulper is designed to minimize energy consumption and environmental impact. By optimizing the pulping process and reducing waste, it contributes to the sustainability goals of the pulp and paper sector.

 

In conclusion, the Hydraulic Pulper is not just a piece of equipment; it is a game-changer that has redefined the pulping process and continues to play a crucial role in the evolution of the pulp and paper industry.

 

 

The Hydraulic Pulper is a specialized machine used in the pulp and paper manufacturing process to break down and macerate fibrous materials into a pulp suspension.

 

The basic structure of a Hydraulic Pulper typically consists of a large, cylindrical tank made of durable material such as stainless steel or cast iron. This tank serves as the containment vessel for the pulping process and is designed to withstand the mechanical forces and chemical reactions that occur during operation.

 

Inside the tank, a rotor or impeller is mounted on a shaft connected to a motor. The rotor is usually designed with blades or vanes that create a swirling motion when rotated at high speed. This rotational motion generates a strong hydraulic force that acts on the fibrous materials introduced into the tank.

 

To start the pulping process, a batch of raw materials, such as waste paper, cardboard, or wood pulp, is loaded into the tank along with a suitable amount of water and, in some cases, chemical additives. These additives can help in enhancing the pulping efficiency, improving fiber separation, and removing impurities.

 

As the rotor spins, the water and the raw materials are mixed vigorously. The mechanical action of the rotor's blades, combined with the hydraulic forces, tears apart the fibrous structure of the raw materials, separating the individual fibers from each other and from any attached contaminants or adhesives.

 

The pulping process in a Hydraulic Pulper is a continuous operation until the desired level of fiber separation and maceration is achieved. The resulting pulp suspension is then discharged from the tank through an outlet and sent to the next stage of the papermaking process, where it undergoes further refinement and treatment.

 

In terms of performance, the efficiency and effectiveness of a Hydraulic Pulper depend on several factors, including the rotational speed of the rotor, the design and size of the blades, the capacity of the tank, and the type and amount of raw materials being processed. Different models and sizes of Hydraulic Pulpers are available in the market to meet the specific requirements of various pulp and paper production facilities, ranging from small-scale operations to large industrial plants.

 

Overall, the Hydraulic Pulper is a vital piece of equipment that plays a crucial role in converting raw fibrous materials into a usable pulp suspension, which is the fundamental building block for the production of paper and other paper-based products.
