Abstract
A system can include a dry powder mixing tank, a first powder input, a second powder input, a powder output, and a detection device. The first powder input and the second powder input can introduce powders containing different substances that become mixed in the dry powder mixing tank. The detection device can detect information about amounts of different substances in a blend of powder moved out of the tank by the powder output. In some aspects, portions of the blend that do not satisfy parameters for the blend can be diverted from a receptacle for the blend based on the detected information.
Claims20
A system comprising:
- a dry powder mixing tank having (i) at least one input port for receiving first dry powder that includes a first substance and for receiving second dry powder that includes a second substance having a chemical composition different from the first substance, and (ii) an output port for outputting a blend of the first dry powder and the second dry powder into a conduit;
- a detection device proximate the conduit and arranged for detecting amounts of the first substance and the second substance in the blend in the conduit;
- and
- at least one valve controllable to route the blend in the conduit in response to information from the detection device about an amount of the first substance or the second substance in the blend.
A system comprising:
- a dry powder mixing tank having at least one input port for receiving dry powders;
- a rotary feeder arranged for moving a blend of powders out of the dry powder mixing tank;
- a conduit arranged for receiving the blend of powders from the rotary feeder;
- a vacuum pump in communication for moving dry powder relative to one of the dry powder mixing tank or the conduit;
- and
- a blower in communication for moving dry powder relative to the other of the dry powder mixing tank or the conduit.
A method comprising:
- receiving a first powder and a second powder into a dry powder mixing tank;
- moving a blend of powder from the dry powder mixing tank through a conduit;
- determining an amount of the first powder or the second powder in the blend of powder moving through the conduit;
- and
- routing, by a valve assembly, the blend of powder from the conduit based on the determined amount of the first powder or the second powder in the blend of powder moving through the conduit.
