摘要:
A vertical hydro-hoist for conveying a slurry under pressure by using a liquid obtained from a chemical process as a driving liquid and method for operating the same, the hydro-hoist includes at least one feed chamber and a detector for detecting a relationship of specific gravities between a driving liquid, a slurry and a float desporent in the at least one feed chamber. A holding member is provided for holding the float and a device, provided for supplying or discharging a specific gravity adjusting liquid into and out of the float. After temporarily holding the float in the feed chamber, the adjusting liquid is supplied into or discharged out of the float in accordance with the relationship detected by the detector.
摘要:
Slurry consisting of water and solid material is fed to fill a plurality of supply chambers arranged in parallel to each other, by the action of slurry pump. The filled slurry is forced to a transferring pipe by the liquid pressure of a high pressure driving liquid pump. A float is positioned on an interface between the slurry and driving liquid within the supply chamber. When a sensor for detecting the position of the float is inoperative due to an external turbulence or the like, a command signal is applied to selected valves in response to a period of time set in a timer.
摘要:
Slurry consisting of water and solid material is fed to a plurality of supply chambers arranged in parallel to each other by a low pressure slurry pump, and the filled slurry is transferred to a transferring pipe under liquid pressure of a high pressure driving liquid pump. Also, to the upper and lower portions of the supply chambers are connected driving liquid supply/discharge pipes and slurry supply/discharge pipes having valves. The valves are selectively opened/closed in accordance with a detection of a float position within each supply chamber to thereby feed the slurry continuously under pressure. Upon the slurry pressure feeding, the valves connected to the supply chamber lower portion are prevented from closing due to a packing condition.
摘要:
An apparatus for making the supply of a material liquid and relief of pressure of a reaction product liquid in a high-pressure liquefaction reaction such as direct liquefaction of coal. The apparatus includes at least one cylinder having two working chambers separated by a movable float, one of which is adapted to receive the material liquid while the other is adapted to be charged with high-pressure product liquid. A gas discharging pipe having a valve is connected to the side of the cylinder to which the high-pressure product slurry is to be charged. For delivering the product slurry from the cylinder to the outside of the system, the pressure in the cylinder is beforehand relieved and the gases separated from the product slurry are discharged through the valve of the gas discharging pipe. Thereafter, the product slurry filling the cylinder is delivered to the outside by a low pressure of the material slurry supplied to the other side of the cylinder.

摘要:
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.
摘要:
An automatic slurry concentration control system including a mixing tank filled with a charge of slurry of solids containing water, a clear water tank for supplying clear water, a suction tube of a slurry supply pump located in an opening in a lower portion of the mixing tank, and a movable tube for adjusting the opening of the mixing tank, wherein the concentration of slurry in the suction tube can be controlled by adjusting the movable tube, is provided with a clear water control device. The clear water control device is mounted in the clear water tank for controlling the amount of clear water supplied from the clear water tank in accordance with the amount of slurry delivered from the mixing tank.
摘要:
A mine cooling power recovery system wherein a low-pressure slurry pump for charging the mud slurry produced in a mine into a pressure changeover feed chamber is arranged in parallel to a warm water charging low-pressure pump and each of outlets of the two pumps has a changeover valve so that a single power recovery system pumps up both the mud slurry and a warm water out of the mine. A slurry sedimentation tank may be provided on the ground surface.
摘要:
An apparatus including at least one horizontal feed pipe from which a mixture of liquid and particulate solid material to be transported is discharged into a high-pressure transport pipe by the action of a driving liquid delivered through a vertical pipe connected to the horizontal feed pipe to apply pressure to the mixture in the horizontal feed pipe through an intermediate liquid having a specific gravity lower than that of the mixture and higher than that of the driving liquid. Prior to initiation of an operation, the horizontal feed pipe and a lower portion of the vertical pipe below a float mounted therein are charged with the intermediate liquid and an upper portion of the vertical pipe above the float is charged with the driving liquid. Upon the mixture being delivered by a low-pressure mixture pump to the horizontal feed pipe, the intermediate liquid flows into the vertical pipe and raises the level of the float to return the driving liquid from the vertical pipe to its tank. Then, the driving liquid is delivered by a high-pressure driving liquid pump to the vertical pipe from which the intermediate liquid is forced into the horizontal feed pipe to thereby discharge the mixture from the latter into the high-pressure transport pipe, thereby transporting the particulate solid material to a predetermined destination. A mixture feeding device and an intermediate liquid feed device and their modifications are disclosed.
摘要:
A control system for an apparatus for hydraulically transporting sedimentation prone slurry containing pulverized or powdered solid material mixed with water. A pipeline resistance of a slurry transport pipe at a proper location is detected by varying the flow rate of the slurry at the starting point of slurry transportation, and the critical flow velocity for slurry sedimentation is determined by using the pipeline resistance. The slurry is economically transported at the flow velocity above the critical flow velocity.
