Water quality, quantitative continual feeder null of bottom material revised construction method and revised

摘要

PURPOSE: To improve water quality and bottom sediment by automatically and uniformly sprinkling a water quality and bottom sediment modifier such as lime and to obtain a device quantitatively and continuously supplying the modifier. ;CONSTITUTION: In a water quality and bottom sediment improving method, a granular water quality and bottom sediment modifier is continuously emitted from the opening 7 formed to one side part of the bottom surface of the cylindrical hopper 2a arranged on a working ship and continuously and uniformly sprinkled to the outside of the working ship by an centrifugal sprinkler while the working ship is moved. A device for quantitatively and continuously supplying the modifier consists of the cylindrical hopper 2a and a plurality of spindles 5 provided side by side in a freely slidable manner in a mutually spaced apart state so as to close the bottom surface of the hopper 2a and draws out a part of the arbitrary spindle 5 to form an emitting opening to one side part of the bottom surface of the hopper 2a.;COPYRIGHT: (C)1995,JPO
