Definitions
- FIG. 1A wherein a two-component mixture, for example, water 2 and oil 3 have been allowed to settle within mixing tank 1.
- a two-component mixture for example, water 2 and oil 3
- stirring has begun as shown by arrow 4 and the resultant force exerted upon the fluids exhibits itself particularly at the surface of fluid 3 and at the interface between fluids 2 and 3. This phenomenon is further accentuated as stirring continues 15 as seen in Fig. 1C.
- vortex formation becomes more acute- the top surface of fluid 3 becomes markedly depressed at 6 while a significant segment of fluid 2 rises at the center of the vortex so that areas 5 and 6 approach each other and, under intense mixing, touch.
- Prior art mixing tanks have attempted to minimize disruptions in natural vortex formation by selectively placing baffles against the vertical side walls of the mixing tank.
- the baffles act to induce the fluid materials to move vertically and mini ⁇ mize stratification within the tank.
- the baffles act as a resistance to fluid movement within the tank and greatly increase the power requirements necessary to establish and maintain acceptable fluid mixing.
- -It is thus an object of the present invention to teach a device to maximize fluid mixing.
- Fig. 3 is a cross-sectional schematic of a preferred embodiment of the present invention.
- Fig. 4 is a cross-sectional schematic of an even more preferred embodiment of the present invention.
- a device for the mixing of materials such as two or more immiscible fluids, is taught.
- the device comprises a mixing tank 1 having a substantially circular cross-section.
- a fluid inlet pipe 7 having at least one inlet 8 located , below the intended level of the fluid to be mixed 5 within the mixing tank.
- the tank also embraces a fluid exit pipe 10 having at least one fluid outlet 11 below the intended level of the fluid to be mixed within the tank. Fluid exit 11 is positioned so that the fluid being discharged from pipe 10 moves substan- 10 tially tangentially to the side wall of the mixing tank.
- Inlet pipe 7 and exit pipe 10 are connected to an inline motionless mixer, such as a Komax mixer, which provides the fluid flow within the mixing tank.
- inlet pipe 7 is opened at its top 13, which allows for the addition of concentrated components to be mixed.
- inlet pipe 7 is opened at its top 13, which allows for the addition of concentrated components to be mixed.
- Fig. 4 illustrates yet another improved
- inlet pipe 7 has been moved proximate the side wall of tank 1 ideally diametrically opposite to the position of inlet pipe 10. Having the inlet ports 8 tangentially positioned as are the exit ports 11, it has been
- premixing can again be accomplished by introducing fresh components to the top of inlet pipe 7 at 13, the premixing being done in pump 9 as well as in inline motionless mixer
- inlet 14 is provided downstream of pump 9 for the introduction of air or any other suitable gas to aerate the fluid within the mixer.
- valve 15 can be located
- OMPI drawing fluid as shown in Fig. 4, pump 9 acts as a transfer pump to encourage the passage of fluid through valve 15. It should be noted that with such an arrange ⁇ ment, the fluid can continue to be mixed while transferring fluid to the next processing station.
- pump 9 acts as a transfer pump to encourage the passage of fluid through valve 15. It should be noted that with such an arrange ⁇ ment, the fluid can continue to be mixed while transferring fluid to the next processing station.
- the present invention was described as a device which enhances vortex formation and thus results in more efficient mixing, other advantages inherent in practicing the present invention would clearly be obvious to those skilled in this art. For example, often times when a mixing operation is shut down, a heavy slurry will settle at the bottom of the mixer and form a dense region of high resistance. In a conventional mixing tank, the mixing blades are caused to begin turning when embedded in such a thick slurry, and it is often difficult if not impossible to commence fluid movement within the mixing tank.

Abstract
Dispositif permettant le melange de materiaux, comprenant un recipient de melange (1) presentant une section transversale sensiblement circulaire, une conduite d'entree de fluide (7) possedant au moins un orifice d'entree (8) situe au-dessous du niveau prevu du fluide destine a etre melange a l'interieur du recipient de melange, une conduite de sortie de fluide (10) possedant au moins un orifice de sortie de fluide (11) situe au-dessous du niveau prevu du fluide destine a etre melange a l'interieur du recipient de melange, la sortie de fluide etant sensiblement tangentielle a la paroi laterale du recipient de melange. La conduite d'entree de fluide (7) et la conduite de sortie de fluide (10) sont destinees a etre connectees par l'intermediaire d'une pompe de fluide (19) et, dans un mode de realisation preferentiel, un melangeur sans mouvement en ligne est place en aval de la pompe.
