Title:
GRAVITY SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/051578
Kind Code:
A1
Abstract:
Provided is a gravity separation device wherein occurrences of shelving, flashing, and the like inside the device can be suppressed, variations in the flow rate of underflow obtained by gravity separation can be minimized and underflow can be stably extracted.
This gravity separation device 1, which separates overflow and underflow using differences in specific gravity from mixed material including two or more types of particles having different specific gravities, is provided with a separation section 11 that has a supply pipe 13 for supplying a slurry of the mixed material at the top and separates that slurry into overflow and underflow, and a deposition section 12 that is positioned below the separation section 11 and wherein the underflow that has been separated by precipitation is deposited. An extraction pipe 21 for extracting the underflow is connected to the deposition section 12, and a valve 22 for extracting the underflow and a metering pump 23 for quantitatively extracting the underflow are provided in the extraction pipe 21.
