ABSTRACT:
An apparatus is provided for mixing metered quantities of a plurality of liquids in accurately constant proportions according to a continuous process. The apparatus comprises one storage tank for each of the liquids which must be mixed, each storage tank being provided with an inlet conduit and an outlet conduit, the output of the inlet conduit and the input of the outlet conduit being axially aligned one opposite the other within the corresponding tank, each of said outlet conduits having a liquid pump and a metering orifice one of which is fixed and the other or others being micrometrically adjustable, all said liquid pumps being driven by a single and the same motive power source, each storage tank having a float therein capable of controlling an inlet valve inserted in the corresponding inlet conduit. A more sophisticated embodiment includes an additional tank also having inlet and outlet conduits whose respective output and input are axially aligned one opposite the other, the output of said metering orifices being connected to a mixer section the output of which is connected to said inlet conduit of said additional tank, the outlet conduit of the latter being connected to the intake of an additional liquid pump the exhaust of which includes a final product discharge valve controllable by an hydraulic control valve actuatable by a float provided within said additional tank thus controlling the output of final product in accordance with the liquid level in the additional tank.
