Valve devices, systems, and methods for controlling the distribution of materials
The various embodiments of the present invention are directed to valve devices, systems, and methods for controlling the distribution of materials to multiple locations. The improved valve devices, materials distribution systems, and materials distribution methods disclosed herein are particularly suitable for use in applications where the materials being distributed are, for example but not limited to, non-gaseous fluid materials (e.g., raw liquids, solutions, slurries, colloids, suspensions, and the like) and solid materials having some level of tackiness, moisture content, or like property. The valves, systems, and methods disclosed herein can be operated without having to stop the flow of materials therethrough in order to change the position of the valve from one outlet to another. Further, the valves and systems disclosed herein have few directional changes, therefore there are few, if any, points within the system where the material can get stuck and/or lodged.
1. A method of outputting a material, comprising:
feeding the material into an inlet of a rotary valve device;
directing a first portion of the material into a tapered first outlet with a rotatable discharge chute, wherein a fraction of the first portion of the material is also directed into the first outlet with a funnel trough to prevent splashing or bounce-back of the material into an unintended outlet;
rotating the rotatable discharge chute from the first outlet to a tapered second outlet; and
directing a second portion of the material into the second outlet with the rotatable discharge chute, wherein a fraction of the second portion of the material is also directed into the second outlet with the funnel trough to prevent splashing or bounce-back of the material into an unintended outlet and the funnel trough is above the first outlet and the second outlet.
2. The method of claim 1 further comprising rotating the rotatable discharge chute continuously from the first outlet to the second outlet such that the rotatable discharge chute does not stop at the first outlet or the second outlet.
3. The method of claim 1 further comprising rotating the rotatable discharge chute continuously from the first outlet to the second outlet and to a third outlet such that the rotatable discharge chute does not stop at the first outlet, the second outlet, or the third outlet.
4. The method of claim 1 further comprising directing the material into the first outlet and the second outlet at the same time.
5. The method of claim 1 , wherein the first portion of the material and the second portion of the material flow continuously through the rotary valve device without stopping.
6. The method of claim 5 , wherein the first portion of the material and the second portion of the material are tacky.
7. The method of claim 1 further comprising providing the position of the discharge chute at any position of the discharge chute.
8. A method of outputting a material, comprising:
feeding the material into an inlet of a rotary valve device;
transporting a first portion of the material through a rotatable discharge chute and to a tapered first outlet, wherein during the transportation a fraction of the first portion of the material splashes or bounces back from the first outlet;
funneling back to the first outlet the fraction of the first portion of the material that splashes or bounces back from the first outlet with a funnel trough;
transporting a second portion of the material through the rotatable discharge chute and to a tapered second outlet, wherein during the transportation a fraction of the second portion of the material splashes or bounces back from the second outlet; and
funneling back to the second outlet the fraction of the second portion of the material that splashes or bounces back from the second outlet with the funnel trough, wherein the funnel trough is above the first outlet and the second outlet.
9. The method of claim 8 further comprising rotating the rotatable discharge chute from the first outlet to the second outlet.
10. The method of claim 8 further comprising transporting the material into the first outlet and the second outlet at the same time.
11. The method of claim 8 , wherein the material comprises pellets.
12. The method of claim 11 , wherein the pellets are tacky and wherein the tacky pellets are continuously moving in the rotary valve.
13. The method of claim 11 , wherein the material further comprises liquid.
14. The method of claim 8 further comprising providing the position of the discharge chute with an encoder.
15. The method of claim 8 further comprising receiving the position of the discharge chute at any position of the discharge chute.
16. The method of claim 8 further comprising bagging the first portion of the material.
17. The method of claim 8 further comprising feeding the first portion of the material from the first outlet into a first bagging system and feeding the second portion of the material from the second outlet into a second bagging system.
18. The method of claim 8 further comprising conditioning the first portion of the material.
19. A method of outputting a material, comprising:
feeding a material into an inlet of a rotary valve device;
transporting the material through a rotatable discharge chute and into a tapered outlet, wherein during the transportation a portion of the material splashes or bounces back from the outlet; and
funneling, with a funnel trough above the tapered outlet, the portion of the material that splashes or bounces back from the outlet back into the outlet.
20. The method of claim 19 further comprising rotating the rotatable discharge chute from the outlet to another outlet while continuously feeding the material into the inlet of the rotary valve device.
21. The method of claim 19 , wherein the material comprises dry pellets, a pellet-fluid slurry, tacky pellets, or combinations thereof.
