Title:
SLURRY TRANSFER FACILITY AND SLURRY FEEDING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/025095
Kind Code:
A1
Abstract:
Provided are a slurry transfer facility and a slurry feeding method with which even when a slurry level in a tank varies, a slurry feeding pipe can be prevented from being blocked by solids and slurry feeding can be stably performed. In a slurry transfer facility (10), which sends a slurry from a first tank (11) to a second tank (12) via a first flow path (F1), at least the first tank (11) is equipped with a level meter (13) for measuring the liquid surface level of the slurry. The first flow path (F1) has: a slurry transfer pump (P); a connection pipe (T0) connecting the first tank (11) and the slurry transfer pump (P); and a first pipe (T1) connecting the slurry transfer pump (P) and the second tank (12) and including a first shutoff valve (V1). Furthermore, a second pipe (T2) branching off from the first pipe (T1) and returning to the first tank (11) and including a second shutoff valve (V2) is provided as a second flow path (F2). The first shutoff valve (V1) and the second shutoff valve (V2) can be switched to be opened or closed on the basis of the measurement result by the level meter (13).
