Abstract
A closed system chemical handling and delivery system includes an enclosure having a sealable opening accommodating the ingress and egress of chemical containers with an interior of the enclosure, a glove opening formed in the enclosure to which a glove is attached to and extends into the interior of the enclosure, a viewing window coupled to the enclosure providing a view into the interior of the enclosure, a chemical delivery drain in fluid communication with the interior of the enclosure, and a mixing valve in selective fluid communication with the chemical delivery drain.
Claims19
A closed system chemical handling and delivery system, comprising:
- an enclosure having a sealable opening accommodating ingress and egress of chemical containers with an interior of the enclosure;
- a glove opening formed in the enclosure to which a glove is attached to and extends into the interior of the enclosure;
- a viewing window coupled to the enclosure providing a view into the interior of the enclosure;
- a chemical delivery drain in fluid communication with the interior of the enclosure and comprising an upper portion that is sloped downward and defines an arcuate ridge that transitions from the upper portion into an intermediate portion, wherein the intermediate portion is cylindrical and defines a ledge surface, wherein the ledge surface forms into a cylindrical portion defining a vertical annular wall, and an arcuate recess formed in the vertical annular wall, wherein the arcuate recess is contoured to transition into a curvature of the vertical annular wall of the cylindrical portion;
- and
- a mixing valve in selective fluid communication with the chemical delivery drain.

A closed system chemical handling and delivery system, comprising:
- an enclosure having a sloped top-front surface defining a sealable opening accommodating ingress and egress of chemical containers with an interior of the enclosure;
- a pair of glove openings formed in a front surface of the enclosure to which a pair of gloves are attached to and extend into the interior of the enclosure;
- a viewing window moveably coupled to the enclosure between an open position and a closed position;
- a fastener engaged with the enclosure and the viewing window when the viewing window is in the closed position to seal the viewing window to the enclosure;
- a chemical delivery drain in fluid communication with the interior of the enclosure, the chemical delivery drain including a cylindrical portion having a generally vertical annular wall defining an arcuate recess that is contoured to transition into a curvature of the vertical annular wall, the cylindrical portion transitions into a conical portion that defines a downstream portion of the chemical delivery drain having a drain opening;
- a mixing nozzle assembly is mounted in the arcuate recess to introduce fluid from the mixing nozzle assembly cyclonically into the cylindrical portion to spiral downward into the conical portion;
- and
- a mixing valve coupled to the drain opening and in selective fluid communication with the chemical delivery drain.
5 more elements
A closed system chemical handling and delivery method, comprising the steps of:
- placing a chemical container having chemical product therein inside a closed system chemical handling and delivery system, the system comprising:
- an enclosure with a sealable opening accommodating ingress and egress of the chemical container with an interior of the enclosure;
- a glove opening formed in the enclosure to which a glove is attached to and extends into the interior of the enclosure;
- a viewing window coupled to the enclosure providing a view into the interior of the enclosure;
- a chemical delivery drain in fluid communication with the interior of the enclosure;
- and
- a mixing valve in selective fluid communication with the chemical deliver drain;
- sealing the sealable opening such that the interior of the enclosure is substantially quarantined from an external environment;
- introducing a desired amount of the chemical product to the chemical delivery drain;
- actuating a mixing nozzle assembly mounted in an arcuate recess of the chemical delivery drain to introduce fluid tangentially into the chemical delivery drain to mix with the desired amount of chemical products introduced to the chemical delivery drain;
- and
- selectively actuating the mixing valve to dispense the chemical product through the mixing valve.
