A part of the driving liquid discharged from an outlet pipe for driving liquid is supplied, under the control of a first flow control means, to a slurry tank in accordance with the amount of the solid matter supplied thereto, so that the concentration of slurry may be kept at all times to be constan
A part of the driving liquid discharged from an outlet pipe for driving liquid is supplied, under the control of a first flow control means, to a slurry tank in accordance with the amount of the solid matter supplied thereto, so that the concentration of slurry may be kept at all times to be constant. Further, a clean liquid is supplied, under the control of a second flow control means, in accordance with the amount of driving liquid supplied to the slurry tank.

1. An apparatus for continuously transferring a slurry by liquid pressure comprising a slurry tank for storing therein a slurry containing solid matter, a plurality of feed chambers, each for temporarily storing therein said slurry from said slurry tank, and a driving liquid tank for storing therein
1. An apparatus for continuously transferring a slurry by liquid pressure comprising a slurry tank for storing therein a slurry containing solid matter, a plurality of feed chambers, each for temporarily storing therein said slurry from said slurry tank, and a driving liquid tank for storing therein a driving liquid having a specific gravity smaller than that of said slurry, arranged such that each said feed chamber is connected, at its bottom portion, with a slurry inlet pipe for supplying said slurry to said feed chamber and a slurry outlet pipe for delivering said slurry from said feed chamber, and, at its top portion with a driving-liquid inlet pipe for supplying said driving liquid to said feed chamber and a driving-liquid outlet pipe for discharging said driving liquid from said feed chamber; a float member being provided inside each said feed chamber, each said float member having its buoyancy chosen as to permit each said float member to be located at the boundary surface between said slurry and said driving liquid, and valves being provided on said inlet and outlet pipes, whereby the valves are opened and closed in accordance with the instructions supplied from detectors for detecting the position of each said float member, thereby continuously transferring said slurry in each said feed chamber by the liquid pressure, characterized in that a part of the driving liquid discharged from each said driving-liquid outlet pipe of each said feed chamber is supplied, under the control of a first flow control means, to said slurry tank in accordance with the amount of the solid matter supplied to said slurry tank; and a clean liquid is supplied, under the control of a second flow control means, to said driving liquid tank in accordance with the amount of the driving liquid supplied to said slurry tank. 2. An apparatus according to claim 1, wherein said first flow control means is constituted by a first detector for detecting the flow rate of said driving liquid supplied to said slurry tank, a second detector for detecting the amount of the solid matter supplied to said slurry tank, and a first flow control valve for controlling the flow rate of the driving liquid in accordance with the detection signals supplied thereto from said first and second detectors. 3. An apparatus according to claim 1, wherein said second flow control means is constituted by a first detector for detecting a liquid level position of said driving liquid tank, a controller for selecting, in accordance with the detection signal from said first detector, one of a plurality of ratio setting means which corresponds to said liquid level position, and a first flow control valve for controlling the flow rate of the clean liquid in accordance with the instruction signal supplied from said controller. 4. An apparatus according to claim 2, wherein said second detector for detecting the amount of solid matter is a belt scale. 5. An apparatus according to claim 3, wherein said first detector for detecting said liquid level position is a float switch.
