摘要： A method for filling an elongated sump which has a plurality of diverter gates emptying into the sump is accomplished by dividing the sump into a plurality of adjacent zones along each side of the sump and adding slurry in each of the zones in sequential order in a direction related to the direction of movement of a dredge removing material from the sump. The sequencing automatically skips the zone where the dredge is removing material and empties it during that period of time in the sequence just previously emptied.

摘要： A process control system for use in movement of slurry material from a first lower level through a vertical flow way to an upper or surface level. In particular, this system is utilized for moving slurried particulate from a subterranean mine level upward through a vertical flow way such as an earth borehole to a surface pumping station or the like. The vertical pump system includes series-connected pumps having variable speed capabilities at the lower level, and the pumps then direct the slurried material through the vertical flow way to an upper level receiving station. The process control monitors the upper level volume, the slurry line pressure in the pipeline underground, and the flow rate in the pipeline underground thereby to select a controller output signal. The output signal is then utilized to control a hydraulic servo mechanism which adjusts the variable speed drive to one or more of the series-pumps thereby to maintain a proper flow rate and pressure through the vertical flow way.

摘要： A thermal dryer used to dry wet material includes a drying chamber and a storage bin. Material is transferred from the storage bin onto a movable support means positioned within the drying chamber. A furnace supplies hot gas to the drying chamber and the gas passes over the movable support means to dry the wet material positioned thereon. The temperature of the gas that has been passed over the wet material is automatically maintained at a preselected temperature by controlling the amount of wet material on the movable support means. The temperature of the gas that has been passed over the support means is controlled independently of the temperature of the gas supplied by the furnace. The amount of wet material in the storage bin is automatically maintained below a preselected amount by controlling the temperature of the hot gas supplied by the furnace to the drying chamber. When the amount of wet material exceeds the preselected amount, the temperature of the hot gas supplied by the furnace is increased. This results in a corresponding increase in the temperature of the gas that has been passed over the wet material. In order to reduce the temperature of the gas that has been passed over the wet material, the amount of wet material positioned on the movable support means is increased. An increase in the amount of wet material transferred from the storage bin to the movable support means results in a reduction in the amount of wet material in the storage bin.

摘要： A method and apparatus for sequence control of vertical movement of slurried particulates from a lower level to the upper levels, more particularly a vertical hoist system for movement of slurry from a subterranean mine area upward through an earthen or cased borehole to a surface station. The vertical pump system includes series-connected pumps having variable speed capability to transport slurry particulate from an underground sump upward to a surface surge tank or other repository. The logic sequence system exercises control over valving sequence between the underground pumps and the vertical borehole in order to control slurry surges during start-up, shut-down and emergency dump operations. Thus, the pump input to the vertical conduit utilizes energy dissipator units as selectively controlled by automated block and by-pass valves to control flow of fluids from the pumps upward through the vertical conduit. Selective control of the dissipator units and valving enable critical start-up, shut-down and the emergency shut-down operations and this is effected by particular sequence control.
