Mechanical system that fluidizes, mixes, coats, dries, combines, chemically reacts, and segregates materials
The present application is directed towards systems for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.
1. A system for mixing a plurality of materials, comprising:
a mixing vessel configured for holding a first material therein;
a vibratory mixer for generating a fluidized bed of the first material in the mixing vessel at a location, the vibratory mixer including a payload plate having a plane and configured to oscillate an entirety of the mixing vessel in a substantially linear direction perpendicular to the plane of the payload plate;
at least one spray nozzle configured for introducing a second material into the mixing vessel at the location; and
a pressure control mechanism incorporated in or coupled to the mixing vessel configured to control a pressure therein.
2. The system of claim 1 , wherein the mixing vessel is sealed to maintain the pressure therein.
3. The system of claim 1 , wherein the pressure control mechanism includes a vent configured to allow air into or out of the mixing vessel.
4. The system of claim 1 , wherein the pressure control mechanism includes a vacuum line configured to couple the mixing vessel to a vacuum source for creating a negative pressure within the mixing vessel.
5. The system of claim 1 , wherein the pressure control mechanism includes a pressure relief valve configured to maintain the pressure within the mixing vessel at or above atmospheric pressure.
6. The system of claim 1 , wherein the at least one spray nozzle is coupled directly to at least one of a top portion, a side portion, or a bottom portion of the mixing vessel.
7. The system of claim 1 , wherein the vibratory mixer is capable of oscillating the mixing vessel at a range of about 50 Hz to about 70 Hz.
8. The system of claim 1 , wherein the mixing vessel is further configured to mix the first and second material in a bulk flow pattern.
9. The system of claim 8 , wherein the bulk flow pattern comprises micro mixing of the first material and the second material.
10. The system of claim 1 , further comprising a sweep gas feed line configured to introduce a drying gas into the mixing vessel.
11. The system of claim 1 , further comprising a mixedness sensor configured to detect mixedness of the first material and the second material in the mixing vessel.
12. The system of claim 1 , further comprising a filter coupled to at least one of a vent, a pressure relief valve, or a vacuum line, and configured to block an unwanted material from passing therethrough.
13. The system of claim 1 , further comprising a cooling jacket coupled to the mixing vessel and configured to cool the mixing vessel.
14. The system of claim 1 , further comprising a heating mechanism coupled to the mixing vessel and configured to heat the mixing vessel.
15. The system of claim 1 , further comprising a temperature sensor coupled to the mixing vessel and configured to detect a temperature of at least one of the first or the second material in the mixing vessel.
16. The system of claim 1 wherein the vibratory mixer is configured to oscillate the mixing vessel at frequencies up to 180 Hz.
17. The system of claim 1 wherein the at least one spray nozzle is configured to spray onto the fluidized bed.
18. The system of claim 1 , wherein the system does not use pneumatics to generate the fluidized bed.
