Title:
APPARATUS FOR ATTENUATING TURBULENT FLOW BY PRESSURE AND FLOW SPEED CONTAINED IN PULP SLURRY INTRDUCING CONDUIT APPARATUS OF HEAD BOX OF PAPER MAKING MACHINE
Document Type and Number:
Japanese Patent JPS5365404
Kind Code:
A
Abstract:
An approach pipe system which delivers pulp suspension to the headbox of a paper machine includes a tank having in its interior an upper gas space and a lower liquid space adapted to contain a liquid the upper surface of which contacts the gas in the gas space. In its interior this tank carries a flexible diaphragm which defines with the tank a flow space separated from the liquid space by the flexible diaphragm. A supply pipe communicates with this flow space for delivering a pulp suspension thereto while a discharge pipe also communicates with the flow space for receiving a pulp suspension therefrom and for continuing the travel of the pulp suspension to a headbox. The gas in the gas space acts through the liquid in the liquid space on the diaphragm to damp pressure and flow rate disturbances in the pulp suspension flowing toward the headbox.
