Abstract
A venturi ejector for forcibly ejecting a slurry or solution generated in a fluid dispenser, wherein the venturi ejector includes a venturi, the venturi being in a first flow communication with the slurry or solution and developing a vacuum, the vacuum being in a second flow communication with atmospheric pressure, the second flow communication acting to cause the atmospheric pressure to exert a pressure on the slurry or solution, thereby forcing the slurry to the venturi where the slurry or solution is forcibly ejected from the venturi. A method for forcibly ejecting a slurry or solution generated in a fluid dispenser is further included.
Claims23
A chemical dispenser configured to dispense a dissolved solid cast chemical solution at a pressure sufficient to enable transportation of the solution through a fluid conduit at heights that exceed the height of the dispenser, the dispenser comprising:
- a single supply valve acting to selectively enable the flow of a pressurized water supply;
- a flow splitter acting to split the pressurized water supply into a first fluid flow and a second fluid flow, wherein the flow splitter includes a manually adjustable valve configured to selectively adjust the split of the pressurized water supply between the first fluid flow and the second fluid flow, wherein the first fluid flow is diverted to dissolve a solid cast chemical to form a first fluid flow slurry or solution, and the second fluid flow continues along a path through a high flow rate solid cast chemical bypass;
- a housing including a support surface configured to receive a solid cast chemical container, a collection reservoir configured to collect the first fluid flow slurry or solution, and an atmospheric pressure passageway present between the support surface and the container configured to equalize the pressure of the collection reservoir with the pressure of the surrounding atmosphere;
- and
- a venturi configured to combine the first fluid flow slurry or solution with the second fluid flow, wherein passage of the second fluid flow through the venturi creates a vacuum to pull the first fluid flow slurry or solution from the atmospheric pressure equalized collection reservoir for combination with the second fluid flow, thereby forming a single stream of dissolved solid cast chemical solution, wherein the venturi is vertically oriented at the bottom of the collection reservoir directly below the container.
A method for forcibly ejecting a slurry or solution generated in a fluid dispenser, comprising:
- selectively actuating a single supply valve thereby putting the dispenser in operation and enabling the flow of a pressurized water supply;
- splitting the pressurized water supply into a first fluid flow and a second fluid flow, wherein the pressurized water supply is split via a manually adjustable valve configured to selectively adjust the split of pressurized water supply between the first fluid flow and the second fluid flow;
- forming a first fluid flow slurry or solution by means of the first fluid flow acting on a solid cast chemical contained within a solid cast chemical container supported by a housing support surface;
- collecting the first fluid flow slurry or solution in a collection reservoir, wherein the pressure of the collection reservoir is equalized with the pressure of the surrounding atmosphere by an atmospheric pressure passageway present between the support surface and the container;
- and
- developing a vacuum by means of passing the second fluid flow through a venturi to pull the first fluid flow slurry or solution from the atmospheric pressure equalized collection reservoir for combination with the second fluid flow, thereby forming a single stream of dissolved solid cast chemical solution, wherein the venturi is vertically oriented at the bottom of the collection reservoir directly below the container.
A chemical dispenser comprising:
- a supply valve configured to selectively enable the flow of a pressurized water supply;
- a flow splitter configured to split the pressurized water supply into a first fluid flow and a second fluid flow, wherein the first fluid flow dissolves a solid cast chemical to form a first fluid flow slurry or solution, and the second fluid flow bypasses the solid cast chemical;
- a housing having a support surface configured to receive a solid cast chemical container, a collection reservoir configured to collect the first fluid flow solid cast chemical solution, and a an atmospheric pressure passageway present between the support surface and the container configured to equalize the pressure of the collection reservoir with the pressure of the surrounding atmosphere;
- and
- a venturi configured to create a vacuum to pull the first fluid flow solid cast chemical solution from the atmospheric pressure equalized collection reservoir for combination with the second fluid flow, thereby forming a single stream of dissolved solid cast chemical solution, wherein the venturi is vertically oriented at the bottom of the collection reservoir directly below the container.
