Abstract
A hopper comprises a suction conduit and a pressure conduit each connected to a pump for discharge of the hopper contents, the suction conduit being horizontal and communicating at its free end via a control valve with water outside the hopper, a plurality of vertically extending suction pipes extending downwardly from the suction conduit and spaced above the hopper bottom, each suction pipe having a valve, and cone-shaped bottom valves below the suction pipe open ends for conducting water from outside the hopper to the suction pipes.
Claims3
An improved hopper with floating capacity, said hopper being provided with a pump, a suction conduit connected to the suction side of said pump and a pressure conduit connected to the pressure side of said pump for discharge of the contents, in which the suction conduit extends substantially in horizontal direction to a free end remote from said pump, the suction conduit spaced above the bottom of the hopper, and the free end of the suction conduit communicating with the water from outside the hopper, a number of suction pipes connected at one end thereof to the suction conduit and extending substantially vertically downwardly therefrom to their other ends, the other ends of said pipes being open and terminating a distance above the bottom of the hopper, wherein the improvement comprises means provided below the open ends of the suction pipes for conducting the water from outside the hopper to the suction pipes and a control valve disposed in said suction conduit between its free end and said suction pipes whereby the amount of material drawn through said suction pipes by said pump is controlled by opening or throttling said control valve.
A hopper, said hopper being provided with a pump, a suction conduit connected to the suction side of said pump and a pressure conduit connected to the pressure side of said pump for discharge of the contents, in which the suction conduit extends substantially in horizontal direction to a free end remote from said pump, the suction conduit being spaced above the bottom of the hopper, the free end of the suction conduit communicating with the water from outside the hopper and provided with a control valve, a number of suction pipes connected at one end thereof to the suction conduit and extending substantially vertically downwardly therefrom to their other ends, the other ends of said pipes being open and terminating a distance above the bottom of the hopper, suction pipe valves disposed in each of the suction pipes, said hopper being provided with bottom valves, characterized in that the bottom valves comprise a means for conducting water into the hopper from outside the hopper, said bottom valves being disposed below the open ends of the suction pipes and said bottom valves are adapted in one position to allow the water to flow through from outside while retaining in the hopper its contents.
