Title:
LIQUID DISPERSION METHOD, OR LIQUID DISCHARGING OR APPLYING METHOD, OR DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/251266
Kind Code:
A1
Abstract:
[Problem] In a method involving applying pressure, using compressed air, to a slurry in one of two containers stored in at least one of two or more syringes, opening an air line for applying pressure to a material in the other container so that a liquid is transferred between the two containers through a liquid flow path, and transferring, or discharging while transferring, a liquid such as a slurry by an automatic discharging device provided at or near the middle of the flow path; to prevent the slurry from flowing back to the upstream of the container when a flow rate is increased by increasing the applied pressure to prevent deposition of relatively large particles. [Solution] The present invention provides a preliminary container upstream of a slurry container, inserts a tube or pipe of a compressed air discharge line from the slurry container into the preliminary container, so that, even if a slurry flows back, the slurry is retained in the preliminary container and the slurry is prevented from flowing back upstream of the preliminary container. In addition, the present invention prevents minute droplets from flowing back upstream, by using a protector, or an air-permeable screen.
