Hydraulic headbox tissue paper making machine
This tissue paper machine consist of hydraulic head box, Fourdrinier wire, Yankee touch press, Yankee dryer, dryer hood, mechanical/electric drive, air control system, sole plate, pope reel etc.
To ensure output paper quality and capacity, this machine adopts hydraulic headbox. Headbox lip width 3150mm. Headbox pulp consistency is 0.1-0.5%. Suitable pulp temterature is 20-30°C. Headbox lip opening range is 0-70mm and horizontal adjust range is 0-25mm. The design reflux is 10%.
Main function of headbox: Headbox is to evenly distribute the pulp in the transverse direction of the whole paper machine, and reduce the fiber flocculation as far as possible, so as to produce uniform and quantitative paper.
Headbox main structure:
|1||Main pulp inlet pipe||
According to the theory of fluid mechanics, the distributor with equal pressure and velocity is designed and manufactured. The conical and parabolic designs ensure the uniform distribution of pulp in the paper machine.
|2||Pulp distribution orifice||
It is used to guide the slurry of the square cone main pipe into the headbox transversely, which plays the role of uniform slurry distribution.
The specially designed dilution orifice (zone width is about 70mm) ensures that the slurry is fully mixed with the diluted white water.
When the pulp with dilution water enters the throttle plate, strong turbulent mixing occurs, which makes the slurry water fully mixed.
The pulp flows through the balance chamber of the high turbulence headbox to ensure the ideal micro turbulence and balance the possible non-uniformity of the pulp in the transverse direction of the paper machine.
Through the high turbulence generator, the pulp flow can ensure the ideal micro turbulence, fully disperse the fibers in the pulp, prevent the occurrence of fiber flocculation, and ensure the paper has good uniformity.
