Abstract
A mixer for mixing a solid or an additional liquid into a liquid within a mixing vessel using a vortex action obviates direct application of the introduced solid or liquid with the downstream end of the vortex by bending the axis of rotation of the vortex. In one form this is effected by laterally offsetting a discharge outlet of the mixing vessel relative to the upper end portion of the vessel into which the liquid is introduced. The vortex within the vessel is maintained at a predetermined level by applying a static head to the liquid in the vessel. This is preferably achieved by maintaining a predetermined static head of mixture in an outer vessel into which the mixing vessel discharges.
Claims34
A mixer for mixing either a solid or an additional liquid into a liquid, the mixer including means for generating a vortex in the liquid within a mixing vessel, and means for introducing the solid or the additional liquid to the vortex, wherein the mixing vessel is shaped such that the solid or additional liquid is unable to be directly applied to a downstream end of the vortex.
A mixer for mixing either a solid or an additional liquid into a liquid, the mixer including means for generating a vortex in said liquid within a mixing vessel, and means for introducing the solid or the additional liquid to the vortex, wherein the mixing vessel is at least partially within an outer vessel, the outer vessel extending above a discharge outlet of the mixing vessel and being in fluid communication with said discharge outlet such that the level of liquid in the mixing vessel is dependent on the liquid level within the outer vessel.
A mixer for mixing either a solid or an additional liquid into a liquid, the mixer including means for generating a vortex in said liquid within a mixing vessel, means for introducing the solid or the additional liquid to the vortex, and means for providing a static head of said liquid in the mixing vessel to maintain a predetermined level of the liquid in the mixing vessel.
A mixer for mixing either a solid or an additional liquid into a liquid, the mixer including means for generating a vortex in said liquid within a mixing vessel, and means for introducing the solid or the additional liquid to the vortex, wherein the mixing vessel has at an upper end a large diameter portion which leads via a transition zone into a lower portion of substantially reduced diameter.
A mixer according to claim 31, comprising means associated with the outer vessel to facilitate removal of air within the mixture within the outer vessel prior to withdrawal therefrom.
