ABSTRACT:
A chemical-mixing and dispensing apparatus for providing a volume of a chemical mixture to a dispensing location includes a suitably connected and monitored water main flow coupled to one inlet of a Tee fitting, a fixed-volume container having therein a liquid detergent concentrate, the container being coupled to the other inlet of the Tee fitting. The outlet of the Tee fitting is placed in flow communication with a chemical mixture holding tank along one branch and with a control tank along another branch. The chemical mixture holding tank has an output line which is monitored by an electrically timed solenoid valve for controlling the dispensing of the contents of the holding tank to a spray nozzle. Flow to the control tank is monitored by a pressure regulator such that the pressure ceiling within the control tank remains at a level which is below the pressure ceiling of the holding tank. The control tank is coupled to the fixed volume container such that as flow from the control tank enters the fixed-volume container, equal volume of detergent concentrate is pushed out. Due solely to pressure differences created within the flow loop, caused by dispensing of the mixture from the mixture holding tank, flows of both liquid detergent concentrate and water occur and these flows are mixed by the Tee fitting.
