Slurry dispenser for radioisotope production

摘要

A slurry dispensing system (10) is disclosed. A peristaltic pump (28) may direct a flow of slurry out of a horizontal mixer (20) to a slurry dispenser (140). This slurry dispenser (140) may be operated on a programmed manner by a controller (260) to dispense slurry into a container (36). Both a bypass valve (172) and a dispensing valve (204) of the slurry dispenser may be opened/closed on a programmed basis by the controller (260) to deliver slurry to a container (36), such as a glass column. Slurry may be intermittently directed into a metering chamber (194) of the slurry dispenser (140), while the remainder of the slurry being directed into the slurry dispenser (140) may be recirculated back to the horizontal mixer (20).

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 slurry bypass channel fluidly connectable with each of said mixer outlet and said mixer recirculation port; a metering chamber; a metering chamber inlet valve between said slurry bypass channel and said metering chamber; a metering chamber outlet valve for said metering chamber; a slurry inlet channel extending from said slurry bypass channel to said metering chamber, wherein said metering chamber inlet valve controls a flow through said slurry inlet channel to said metering chamber; an injection needle in fluid communication with said metering chamber; and a controller configured to execute a container slurry-loading sequence comprising closing said metering chamber outlet valve, thereafter opening said metering chamber inlet valve, thereafter closing said metering chamber inlet valve, thereafter opening said metering chamber outlet valve, and initiating a fluid flow through said injection needle after said metering chamber inlet valve has been closed.
