Abstract

A method and apparatus for obtaining a product chemistry from a product and a fluid is provided. A product is housed within a dispenser. A fluid is introduced through a manifold diffuse member having a plurality of ports. A cover is positioned adjacent the manifold diffuse member and includes a plurality of ports. The cover is able to be adjusted, for example, by rotating the cover, to align and un-align the manifold diffuse ports and the cover ports. This adjustment controls the flow characteristics of the fluid through the manifold diffuse member and cover to control the characteristics of the fluid in contact with the product. The adjustment of the cover to control the flow will provide a generally consistent concentration and erosion rate based upon known relationships between a characteristic of the fluid and the flow of the fluid in relation to the product.

First claim

What is claimed is:

1. An apparatus for adjusting characteristics of the flow of a fluid contacting a solid product to form a product chemistry, comprising:
a manifold diffuse member comprising a plurality of manifold diffuse ports therethrough and positioned adjacent the solid product, said fluid must pass through a cavity containing the solid product and is directed by a liquid source nozzle in a manner that the fluid passing through the liquid source nozzle will be passed through the manifold diffuse ports;
a cover positioned adjacent the manifold diffuse member and comprising a plurality of cover ports therethrough;
a ramped up body connected to the cover;
a temperature dependent device shaft connected to the ramped body via a ramped shaft member;
wherein the cover is rotatably adjustable relative to the manifold diffuse member; and
wherein the temperature dependent device is configured to rotate the ramped up body to adjust the alignment of the manifold diffuse ports and the cover ports to adjust a characteristic of the flow of the fluid contacting the solid product to adjust the erosion rate of the solid product by the fluid.

2. The apparatus of claim 1 wherein the plurality of cover ports comprises slots positioned radially about the cover and configured to block and unblock the manifold diffuse member ports.

3. The apparatus of claim 1 further comprising:
a product chemistry collector, said product chemistry comprising upstanding waits extending upward from the manifold diffuse member; and
a collection zone proximate to the product chemistry collector; said collection zone configured to receive any product chemistry that may pass through an overflow port in the upstanding walls of the product chemistry collector.

4. The apparatus of claim 1 wherein the temperature dependent device shaft is configured to extend and retract based upon the temperature of the liquid passing through the manifold diffuse member and the cover.

5. The apparatus of claim 4 wherein the extending and retracting of the temperature dependent device shaft causes the cover to rotate relative to the manifold diffuse member, which adjusts the alignment of the manifold diffuse member ports and the cover ports.

6. The apparatus of claim 1 wherein the manifold diffuse member further comprises radial slots therethrough with preset locking points set at selected angular distances about the axis of the manifold diffuse member.

7. The apparatus of claim 6 wherein the cover further comprises notches configured to reside within the radial slots and capable of being rotated between the locking points to adjust the alignment of the manifold diffuse ports and the cover ports between preset configurations.

8. The apparatus of claim 1 wherein the characteristic of the fluid in contact with the solid product comprise:
a. velocity,
b. pressure,
c. turbulence,
d. temperature,
e. flow rate,
f. vector, and/or
g. impingement.

9. A dispenser configured to obtain a product chemistry from a product and a liquid, comprising:
a housing;
a cavity within the housing for holding the product;
a liquid source adjacent the cavity for providing a liquid to contact the product to create a product chemistry;
a manifold diffuse member adjacent the liquid source and solid product and comprising a plurality of manifold diffuse ports therethrough to allow a flow of the liquid to contact the solid product, said liquid from said liquid source being directed in a manner that the liquid will be passed through the manifold diffuse ports;
a product chemistry collector within the housing, said product chemistry collector comprising upstanding walls extending upward from the manifold diffuse member;
a cover positioned adjacent the manifold diffuse member and comprising a plurality of cover ports therethrough;
a ramped body connected to the cover; and
a temperature dependent device shaft connected to the ramped body via a ramped shaft member;
wherein the temperature dependent device is configured to rotate the cover relative to the manifold diffuse member via the ramped body to adjust the alignment of the manifold diffuse ports and the cover ports to adjust a characteristic of the flow of the liquid contacting the product to adjust the erosion rate of the product by the liquid;
wherein the liquid must flow through the cavity and contacts the product.

10. The dispenser of claim 9 further comprising an outlet operatively connected to the cavity to dispense the product chemistry from the dispenser.

11. The dispenser of claim 9 further comprising:
a collection zone positioned below to the product chemistry collector, said collection zone configured to receive product chemistry that passes through an overflow port in the upstanding walls of the product chemistry collector.

12. The dispenser of claim 9 wherein the temperature dependent device shaft is configured to extend and retract based upon the temperature of the liquid passing through the manifold diffuse member and the cover.

13. The dispenser of claim 12 wherein the extending and retracting of the temperature dependent device shaft causes the cover to rotate relative to the manifold diffuse member, which adjusts the alignment of the manifold diffuse member ports and the cover ports.

14. The dispenser of claim 9 wherein the plurality of cover ports comprises slots positioned radially about the cover and configured to block and unblock the manifold diffuse member ports.
