System for small-batch brine production
A system for mixing, for example, salt with water to make brine, includes a mixing vessel removably mounted within a bulk vessel. The mixing vessel is provided with a divider/filtration wall separating a front portion, where solid granular material is provided and mixes with a liquid for purposes of dissolving the solid granular material into the liquid, and a rear portion. The mixing vessel is provided with an agitation pipe along a floor thereof, and is shaped to minimize settled granular material from collecting at the base of the mixing vessel. The divider/filtration wall serves to prevent overflow, includes one or more screens to allow liquid, but prevent granular material larger than the pore size of the screens, to pass from the front portion to the rear portion, and in the event of overflow, minimize turbulence in material passing over the divider/filtration wall, all of which promote delivery of a uniform distribution of dissolved material to the batch tank. In the case of salt brine production, a wireless salinity sensor can accurately measure salt concentration in real time at a variety of depths.
1 . A system for producing a homogeneously-mixed solution, comprising:
a batch vessel;
a mixing vessel supported on and extending into the batch vessel, the mixing vessel comprising a front wall, a rear wall, a pair of opposing sidewalls, and a divider/filtration wall separating the mixing vessel into a first mixing portion and a second filtered portion, the rear wall of the mixing vessel including one or more slots to permit fluid to transfer from the second filtered portion into the batch vessel, the rear wall of the mixing vessel being sloped in a rearward direction from a floor of the mixing vessel.
2 . The system of claim 1 , the divider/filtration wall having one or more mesh screens therein.
3 . The system of claim 1 , the rear wall of the mixing vessel having one or more mesh screens in a lower portion thereof.
4 . The system of claim 1 , further comprising a wireless salinity sensor suspended within the batch vessel.
5 . The system of claim 1 , further comprising a float valve provided in the batch vessel, the float valve in communication with a fluid source and configured to interrupt flow of fluid from the fluid source into the batch vessel upon a fluid level within the batch vessel rising to a predetermined level.
6 . A system for producing a homogeneously-mixed solution, comprising:
a batch vessel;
a mixing vessel supported on and extending into the batch vessel, the mixing vessel comprising a front wall, a rear wall, a pair of opposing sidewalls, and a divider/filtration wall separating the mixing vessel into a first mixing portion and a second filtered portion, the rear wall of the mixing vessel including one or more slots to permit fluid to transfer from the second filtered portion into the batch vessel, the divider/filtration wall having a serpentine cross-section.
7 . A system for producing a homogeneously-mixed solution, comprising:
a batch vessel;
a mixing vessel supported on and extending into the batch vessel, the mixing vessel comprising a front wall, a rear wall, a pair of opposing sidewalls, and a divider/filtration wall separating the mixing vessel into a first mixing portion and a second filtered portion, the rear wall of the mixing vessel including one or more slots to permit fluid to transfer from the second filtered portion into the batch vessel;
the mixing vessel provided with an agitation pipe extending along a floor thereof, the agitation pipe including a plurality of nozzles to supply pressurized fluid into a lower portion of the mixing vessel;
an eductor nozzle secured via an eductor mount to a rear side of the rear wall of the mixing vessel, the eductor nozzle sharing a fluid supply with the agitation pipe; and
a manifold and valve circuit placing the eductor nozzle and the agitation pipe in selective fluid communication with a pump.
8 . The system of claim 7 , and the eductor nozzle having an outlet generally directed toward a floor of the batch vessel.
9 . The system of claim 8 , further comprising an air purge valve and an air supply in fluid communication with the manifold and valve circuit.
10 . The system of claim 7 , further comprising an additive valve to selectively place additive supplied by an additive storage tank into fluid communication with solution collected in the batch vessel as the solution is pumped out of the system.
11 . The system of claim 7 , wherein the nozzles of the agitation pipe are directed toward at least one of the rear wall of the mixing vessel and a floor of the mixing vessel.
