[Also in Divisions G3 and G6] Apparatus for regulating the concentration of a suspension or liquid mixture comprises a tank I for the suspension or heavier component, having at its lowest point a discharge opening 3 connected to the outlet 5 for a heavier separation component of a cyclone 4, which also has an outlet 12, 11 for a lighter separation component and an inlet 6 controlled by an adjustable valve 8. With a high rate of supply of liquid (or lighter liquid component in the case of a liquid mixture) through the conduit 7 and inlet 6, the contents of the tank 1 can be prevented from discharging and by reduction of the rate, increasing quantities of the heavier material are allowed to discharge from the tank and pass into the liquid leaving the cyclone at 12 so that the concentration of the fluid discharged at 11 may be varied from pure liquid as supplied at 6 to a suspension of the same concentration as that stored in or supplied to the tank 1. In a modification, Fig. 2 (not shown), both suspension and liquid are supplied to the inlet 6, unwanted particles being centrifuged out into the tank 1. The suspension in tank 1 may be agitated by gas bubbles as shown, or by a vibrator, a stirrer, or a heater producing convection currents. The solid particles may be particles of fissionable material in a suspension reactor.</p> |
