Description

HOMOGENIZER-MIXER
Subject of the Invention
The invention relates to a novel homogenizer-mixer, which enables the processes of high- efficiency mixing and homogenization to be performed simultaneously inside the same vessel for the production of solutions.
State of the Art
The mixers are used in cases where it is desired to mix one or more than one solid and/or liquid with a liquid to thereby prepare a solution. The mixers are employed for the purpose of enabling the material in a mixture to be dissolved homogeneously in a solvent.
For the production of the solutions of low viscosity, mixing alone might not be sufficient when it is desired to obtain a homogeneous mixture particularly with materials that are difficult to dissolve in water. In such cases, the process of homogenization is employed in order to break up the particles present in the solution to increase their surface area and thus bring the solution into a homogeneous state. The machines performing this process are called homogenizer. The homogenizers are the machines frequently used in the chemical, pharmaceutical, cosmetic and food industries.
According to the state of the art, when both of the processes of high-efficiency mixing and homogenization are needed, the mixing process is realized in a vessel, and subsequently, the mixture is taken out of the vessel in order to perform the homogenization process. In cases where the homogenization process is performed inside the vessel, the mixing process is not performed to thereby ensure that it does not affect the operation of the homogenizer, and only the internal circulation provided by the homogenizer is relied upon. Some practices are also encountered where the mixing process is enhanced by offsetting the homogenizer from the axis and adding an anchor type mixer.
The homogenizers used according to the state of the art usually have a cylindrical homogenization wall. In these homogenizers, which basically operate like a centrifugal pump, the mixture that is drawn into the machine by the suction movement generated by the blades at the center is forced to pass through the spaces surrounding the blades and is broken into tiny pieces under the shear action provided by the blade tips, thereby achieving the homogenization. In these machines, although the sucked liquid is being homogenized, no liquid movement is generated and there is no compression involved during the flow of the sucked liquid. An image of an exemplary homogenizer used according to the state of the art is shown in Figure 1.
The homogenizer-mixer according to the invention differs from the state of the art by its characteristics features such as the wall of the homogenizer and the mixer and therefore the homogenization zone being conical, a slope being provided for the mixer turbine blade used as the flow member and the bottom of the homogenization zone being open towards the vessel bottom. Owing to the characteristic features mentioned above, it is possible, during the preparation of a low-viscosity solution, to obtain a homogeneous mixture by performing the processes of homogenization and high-efficiency mixing inside the same vessel, without taking the solution out of said vessel, even with the materials that are difficult to dissolve in water. of the Invention
An object of the invention is to obtain a homogenizer-mixer wherein the processes of mixing and homogenization may be performed inside the same vessel for obtaining a homogeneous solution.
Another object of the invention is to obtain a homogenizer-mixer enabling the compression of the solution and accordingly an increase in the velocity of the liquid owing to the conical structure having a conical homogenization wall.
Another object of the invention is to obtain a homogenizer-mixer enabling the liquid to be sucked from a greater area than the solution inlet diameter of said homogenizer-mixer, owing to the conical geometry.
Another object of the invention is to obtain a homogenizer-mixer wherein a radial flow turbine with inclined blades is used, the homogenization action is enhanced by increasing the ratio of radial flow/axial flow and it is also possible to generate a strong axial flow.
Another object of the invention is to obtain a homogenizer-mixer wherein the homogenization zone has an open bottom, the radial flow generated in the homogenization zone moves towards the vessel bottom along with the axial flow generated at the turbine center and the internal circulation is provided in the vessel.

Detailed Description of the Invention
The invention relates to a novel homogenizer-mixer (8), which enables the processes of high- efficiency mixing and homogenization to be performed simultaneously inside the same vessel (14) for the production of solutions. More specifically, the invention relates to a novel homogenizer-mixer (8), which enables even the raw materials that are difficult to be dissolved and dispersed to be dissolved, homogenized and at the same time mixed with high efficiency inside a vessel (14) in a single step, without taking the mixture out of the production vessel (14), for the preparation of the solutions of low viscosity.
The homogenizer-mixer (8) according to the invention has in its most basic form at least one conical surface (1), through which the solution that is to be mixed and homogenized passes; at least one mixer turbine blade (6), which, owing to its rotational movement, enables the solution to be sucked into the conical surface (1); at least one suction tube (2), which assists with the suction of the solution; and at least one homogenization zone (3), which is located on the conical surface (1) and which enables the particles and/or the oil phases contained in the solution to be homogenized. In a preferred embodiment of the invention, the suction tube (2) and/or the homogenization zone (3) has/have a structure integral with the conical surface (1) and accordingly, the suction tube (2) and the homogenization zone (3) also have a conical form. The diameter of the conical surface (1) decreases from the conical suction tube (2) towards the homogenization zone (3). In the homogenizer-mixer (8) according to the invention, the turbine is enabled to suck the liquid from an area that is greater than the diameter of the turbine itself by using a conical suction tube (2) integral with the conical surface (1), instead of using a known cylindrical suction tube. The conical homogenization zone (3), having the characteristic of being the continuation of the suction tube (2), continues, unlike the state of the art, also following the termination of the mixer turbine blades (6) and in this way, a greater part of the flow discharged from the tip zone of the mixer turbine blades (6) is subjected to homogenization.
In a preferred embodiment of the invention, the outlet cross-section of the homogenization zone (3) is 30%-70% of the inlet cross-section of the suction tube (2). This means that the homogenization zone (3) is supplied with more liquid than it would be able to suck in based on its diameter. In order for a greater part of the flow discharged from the tip zone of the mixer turbine blade (6) to be subjected to homogenization, the homogenization zone (3) begins at the termination of the suction tube (2) and continues also following the termination of the mixer turbine blade (6).
A preferred embodiment of the invention has at least four turbine blades (6). Further, in a preferred embodiment of the invention, the angles between the turbine blades (6) are equal.
The mixer turbine blade (6) is fixed in the lower region of the conical surface (1), preferably in the middle of the homogenization zone (3), and enable the mixture to be sucked into the conical surface (1) by means of the rotational movement. The location where the diameter of the conical surface (1) is the biggest is the solution inlet diameter (4). The solution inside the vessel (14) achieves entrance to the conical homogenizer-mixer (8) through the solution inlet diameter (4). From the solution inlet diameter (4), the homogenizer-mixer (8) advances with a narrowing diameter. After the solution inlet diameter (4) in the homogenizer-mixer (8), the suction tube (2), which assists with the suction of the solution, begins. And following the suction tube (2), the homogenization zone (3) begins. The mixer turbine blades (6) are positioned in the homogenization zone (3), preferably in the middle of the homogenization zone (3). The homogenization zone (3) continues also after the bottom edge of the mixer turbine blade (6), and as a result of the conical structure, the diameter of the homogenizermixer (8) decreases and the minimum diameter is reached at the lowermost point. The lowermost region of the homogenizer-mixer (8) having the smallest diameter is the solution outlet diameter (5) and, after the bottom edge of the mixer turbine blade (6), the homogenization zone (3) continues up to the solution outlet diameter (5). The mixer turbine blade (6) is the component, which sets in motion the solution inside the vessel (14) and enables the solution to enter the homogenizer-mixer (8) via the solution inlet diameter (4) and to exit the same via the solution outlet diameter (5). The homogenizermixer (8) according to the state of the art is shown in Figure 1. The mixer turbine blades (6) according to the state of the art usually have an angle of 45°. In such systems, the ratio of the radial flow to the axial flow is 1/1. The homogenizer-mixer (8) according to the invention has inclined mixer turbine blades (6) and the angle of the mixer turbine blades (6) is 55-70° so that the homogenization zone (3) may be fed in an intensive manner. In this way, the radial flow is enabled to be 1.5-2.5 times the axial flow; in other words, the ratio of the radial flow to the axial flow is enabled to be in the range of (1.5):1-(2.5):1. Owing to the increased radial flow, the homogenization effect is enhanced and the mixer turbine blade (6) is able to generate a sufficiently strong axial flow to ensure the mixing inside the vessel (14). In a preferred embodiment of the invention, the mixer turbine blade (6) directs 1/3 of the liquid flow it generates to the axial flow and discharges 2/3 of the same via the radial flow. As a result, the homogenization zone (3) surrounding the mixer turbine blade (6) is supplied with about 2 times more flow as compared to the systems of the state of the art. The detailed drawings of the mixer turbine blade (6) are shown in Figure 5.
Due to the conical structure of the homogenizer-mixer (8) according to the invention, there is a difference between the solution inlet diameter (4) and the solution outlet diameter (5). This diameter difference enables the homogenizer-mixer (8) to be supplied with more liquid than it would be able to suck based on its diameter. The conical structure of the homogenizer-mixer (8) forces the sucked solution to pass through a gradually narrowing cross-section and in this way, the solution is compressed by 1.2 to 4 times. Since the volume of the liquid may not change depending on compression, the velocity of the liquid increases by 1.2 to 4 times. There is at least one hole present on the homogenization zone (3). The liquid flow concentrated on the homogenization zone (3) is forced by the mixer turbine blades (6) to pass through the holes in the homogenization zone (3), and in the mean time, the non-dissolved particles in the solution are enabled to be dissolved by the jet currents formed in the holes, or, in case the solution contains a separate oil phase, said phase is enabled to be homogenized by being broken down to very small particles.
The ratio of the overall area of the holes in the homogenization zone (3) to the wall area of the homogenization zone (3) is in the range of l/(1.5)-l/(2.5). In this way, while about half of the liquid flow reaching the homogenization zone (3) passes through the holes by forming a jet, the remaining liquid is directed to the axial flow. Considering that 2/3 of the total flow contacts the homogenization zone (3), 1/3 of the solution set in motion by the mixer turbine blade (6) is homogenized, while the remaining liquid joins, via axial flow, the circulation inside the vessel (14).
Another difference of the homogenizer-mixer (8) according to the invention from the state of the art is that the conical surface (1) and thus the bottom of the homogenization zone (3) are open towards the bottom of the vessel (14). By this means, the axial flow formed in the central region of the turbine is about 4 to 6 times greater than the axial flow formed in the machines used according to the state of the art. This axial flow moves towards the bottom of the vessel (14) along with the radial flow bouncing from the homogenization zone (3) and as a result, the circulation is achieved at the interior of the vessel (14).
Consequently, both processes of mixing and homogenization may be achieved by means of a single fixture located inside the vessel (14).
An exemplary system employing the homogenizer-mixer (8) according to the invention is shown in Figure 2. The system where the homogenizer-mixer (8) according to the invention is used comprises the vessel (14), the motor (15) and the turbine shaft (7). In this exemplary embodiment, the motor (15) is located on the body of the vessel (14) and provides motion to the turbine shaft (7). The turbine shaft (7) is supported by means of the top bearing (13) located at the top of the vessel (14) and the bottom bearing (12) located at the bottom of the vessel (14). The turbine shaft (7) is coupled with the bottom of the vessel (14) via the bottom bracket (11) and the stainless bushing (10). The conical surface (1) is in a state fixed to the mixer turbine blade (6) and the turbine shaft (7). The mixer turbine blade (6) transfers the movement it receives from the turbine shaft (7) to the homogenization zone (3). The homogenizer-mixer (8) is coupled with the bottom of the vessel (14) via the tripod (9). The details of the deep bearing are shown in Figure 4.
