Title:
METHOD AND DEVICE FOR MIXING GAS INTO HIGH-VISCOSITY MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/125900
Kind Code:
A1
Abstract:
The present invention makes it possible to cause a high-viscosity material into which a gas has been mixed to be fed to a subsequent step in a continuous and non-pulsating manner, achieve compatibility with high-viscosity materials having a variety of viscosities, and easily change the expansion ratio of the high-viscosity material. A gas mixing device 1 is provided with: a gas discharge port 14 provided in proximity to a pipeline space through which the high-viscosity material is able to flow; a piston pump 10 provided with a cylinder 11 capable of communicating with the pipeline space through the discharge port 14, a piston 12 disposed in the cylinder, and a driving means for moving the piston in the cylinder between top dead center and bottom dead center; a discharge valve 30 for opening or closing the discharge port 14; and an intake valve 20 for opening or closing a gas intake port via which gas is taken into a cylinder space. When the piston 12 is at top dead center, a cylinder space of a predetermined volume is formed in the cylinder 11. When the piston 12 moves towards the bottom dead center, the tip of the piston approaches the discharge port.
