The Parason Headbox is a cutting-edge innovation designed to elevate the papermaking process through its advanced features and precise control mechanisms. This state-of-the-art technology is engineered to optimize paper quality, enhance production efficiency, and ensure superior performance in papermaking operations.
At the heart of the Parason Headbox is its sophisticated technology and robust construction. With excellent jet quality and precise control over gsm profile, the Parason Headbox maintains consistent paper quality. Its C-clamp design and stainless-steel construction offer durability and uniform nozzle geometry, ensuring long-lasting performance and reliability.
Key Components and Their Functions
1. Functional Body Diagram
The headbox is composed of several essential parts:
- HC Header and LC Header: These headers manage high and low pulp flow, pressure and dilution.
- Dilution Control Valve: Particularly designed in Parason Hydraulic Headbox. It regulates the pulp flow and consistency, preventing floc formation.
- Mixing Chamber and Distribution Tubes: Ensure even distribution and mixing of pulp.
- Stilling Chamber and Turbulence Generator: Optimize laminar flow and pressure for smooth paper formation.
- Top Lip Beam, Slice Blade, and Bottom Lip Beam: Crucial for controlling the pulp flow over the wire section.
2. Dilution Control System
Provided in Parason Hydraulic Headbox, this advanced system maintains optimal pulp flow and consistency, ensuring smooth paper formation by effectively managing the feeding unit.
3. Pulsation Dampening Tank
Essential for maintaining a steady flow of pulp, this tank absorbs and reduces pressure fluctuations, ensuring consistent paper quality.
4. Stilling Chamber
Meticulous engineering in the transition from the distribution chamber to the stilling chamber optimizes flow and pressure, enhancing paper formation.
Types of Headbox
The two main types of headbox that Parason Machinery manufactures and supplies are:
Working Principle of Headbox
The headbox is a critical component in the papermaking process, responsible for delivering a uniform slurry of fiber and water onto the wire section of the paper machine.
1. Pulsation Dampening Tank
The fiber suspension (pulp) enters the Pulsation Dampening Tank, which is designed to reduce pressure fluctuations and pulsations in the flow.
2. HC Header
From the dampening tank, the pulp flows into the HC Header. This header distributes the pulp evenly across the width of the headbox.
3. Dilution Control Valve
The dilution control valves are designed in hydraulic headbox. This valve regulates the amount of water added to the pulp to control its consistency.
4. Mixing Chamber
In the Mixing Chamber, the diluted pulp is thoroughly mixed to ensure uniform consistency and distribution of fibers.
5. Turbulence Generator
A certain amount of turbulence is reintroduced deliberately through the Turbulence Generator. This controlled turbulence helps to keep the fibers uniformly suspended in the water.
6. Nozzle and Lips
The pulp slurry exits the headbox through the Nozzle, which directs the flow onto the wire. The headbox has adjustable lips that control the thickness and velocity of the pulp slurry.
Summary
The headbox functions to convert a pulp slurry into a uniformly distributed, thin layer of fibers on the wire section, ensuring consistent paper quality.
