Mechanical system that fluidizes, mixes, coats, dries, combines, chemically reacts, and segregates materials
The present application is directed towards systems and methods 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 method for mixing a plurality of materials, the method comprising:
generating a fluidized bed in a mixing vessel by oscillating, using a vibratory mixer configured to oscillate at a range of about 50 Hz to about 70 Hz, an entirety of the mixing vessel in a substantially linear direction perpendicular to a top surface of the fluidized bed, the fluidized bed comprising a first material; and
introducing a second material by a sprayer including at least one spray nozzle into the mixing vessel onto the fluidized bed.
2. The method of claim 1 , wherein the mixing vessel is sealed to maintain a pressure therein.
3. The method 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.
4. The method of claim 1 , wherein generating the fluidized bed comprises oscillating the mixing vessel with a displacement amplitude of about 0.02 inches to about 0.5 inches.
5. The method of claim 1 , further comprising mixing the first and second material in a bulk flow pattern within the mixing vessel.
6. The method of claim 5 , wherein mixing the first and second material in a bulk flow pattern comprises micro mixing of the first material and the second material.
7. The method of claim 1 , further comprising introducing a drying gas into the mixing vessel via a sweep gas feed line.
8. The method of claim 1 , further comprising detecting a mixedness of the first material and the second material in the mixing vessel using a mixedness sensor.
9. The method of claim 1 , further comprising blocking an unwanted material from passing through at least one of a vent, a pressure relief valve, or a vacuum line coupled to the mixing vessel via a filter.
10. The method of claim 1 , further comprising cooling the mixing vessel via a cooling jacket coupled to the mixing vessel.
11. The method of claim 1 , further comprising heating the mixing vessel via a heating mechanism coupled to the mixing vessel.
12. The method of claim 1 , further comprising detecting a temperature of at least one of the first or the second material in the mixing vessel using a temperature sensor coupled to the mixing vessel.
