SLURRY DISPENSER FOR RADIOISOTOPE PRODUCTION

摘要

A slurry dispensing system is disclosed. A peristaltic pump may direct a flow of slurry out of a horizontal mixer to a slurry dispenser. This slurry dispenser may be operated on a programmed manner by a controller to dispense slurry into a container. Both a bypass valve and a dispensing valve of the slurry dispenser may be opened/closed on a programmed basis by the controller to deliver slurry to a container, such as a glass column. Slurry may be intermittently directed into a metering chamber of the slurry dispenser, while the remainder of the slurry being directed into the slurry dispenser may be recirculated back to the horizontal mixer.

主权项

1. A slurry dispensing system comprising: 1) a slurry mixer comprising a mixer outlet and a mixer recirculation port; and 2) a slurry dispenser fluidly connectable with said slurry mixer and comprising:
a housing assembly comprising a plurality of separate housings that are disposed in a stack; a slurry bypass channel fluidly connectable with each of said mixer outlet and said mixer recirculation port, wherein said slurry bypass channel extends completely through said housing assembly; a slurry flow channel that extends from said slurry bypass channel, that is disposed within said housing assembly, and that proceeds through said stack to a perimeter of said housing assembly, wherein said slurry flow channel comprises a metering chamber; a metering chamber inlet valve between said slurry bypass channel and said metering chamber; and a metering chamber outlet valve for said metering chamber.
