PURPOSE:To obtain a large amount of uniform muddy water quickly at once by sucking surface layer water in a water tank together with the introduced material by means of a pump provided with an impeller and injecting it as jet flow to the inside of said water tank from a discharge port of the pump to generate circulating flow. CONSTITUTION:A suction port side of a pump 6 provided with an impeller 9 is arranged in a water tank 1 and also a jet nozzle 15 which is opened toward the lower part of water surface via a passage such as a hose 14 is provided to the discharge port side of said pump 6. The floating material 21 such as bentonite thrown in an inflow box 11 at the suction port side of the pump 6 is sucked together with the surface layer water to the pump 6 and after the cutting and separation of said material 21, the mixing and stirring with water are performed with the impeller 9 while passing through the impeller 9, circulating flow is generated in the tank 1 by sending the mixture to the discharge side and injecting it from the nozzle 15. As a result, a large amount of uniform muddy water can be obtained quickly at once without relation to the size of the water tank and without requiring a mixer. |
