Abstract
Abstract In apparatus for dissolving and admixing components having a highly different specific gravity in liquid to highly viscous media, a blade wheel surrounded by a guide ring is used as a pumping member to create in the liquid medium a suction zone, which contains a discharge opening of a conduit for supplying the substances having a relatively low specific gravity. The supply conduit is provided at its end remote from the blade wheel with a feeder or the like for the powders, and its discharge opening is disposed within the guide ring and as close as possible to the revolving elements of the blade wheel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
165 words
Apparatus for dissolving and admixing components having a highly different specific gravity in liquid to highly viscous media comprising a pumping member which is adapted to be immersed in a liquid medium and which is composed of a blade wheel which is surrounded by a guide ring and serves to create a suction zone in said liquid medium, a conduit for supplying substances which have a lower specific gravity than said liquid medium, said conduit having a discharge opening disposed in said suction zone, said conduit being provided at its end portion opposite to said blade wheel with means for feeding said substances thereto, means incorporated in said conduit for force-feeding such substances to the suction zone so that such substances enter the pumping member in reaction to the suction of the blade wheel and the discharge pressure of said feeding means, and said discharge opening at the other end of said conduit being disposed within said guide ring and close to said blade wheel.
Claim 2
Dependent Claim
165 words
Apparatus for dissolving and admixing components having a highly different specific gravity in liquid to highly viscous media comprising a pumping member which is adapted to be immersed in a liquid medium and which is composed of a blade wheel which is surrounded by a guide ring and serves to create a suction zone in said liquid medium, a conduit for supplying substances which have a lower specific gravity than said liquid medium, said conduit having a discharge opening disposed in said suction zone, said conduit being provided at its end portion opposite to said blade wheel with means for feeding said substances thereto, means incorporated in said conduit for force-feeding such substances to the suction zone so that such substances enter the pumping member in reaction to the suction of the blade wheel and the discharge pressure of said feeding means, and said discharge opening at the other end of said conduit being disposed within said guide ring and close to said blade wheel.
Claim 3
Dependent Claim
38 words
Apparatus as set forth in claim 1, characterized in that said force-feeding means comprises an injector, which is fed by a high-pressure pump and supplies the blade wheel with a mixture of the entraining liquid and the powders.
Claim 4
Dependent Claim
28 words
Apparatus according to claim 1, characterized in that said guide ring surrounding the blade wheel is carried by a tube which supplies said substances into said suction zone.
