Definitions
- the invention relates to an arrangement for mixing a medium with an element for generating a movement in the medium, wherein the element is in communication with a drive.
- Mixing is a basic operation in mechanical engineering. Arrangements for mixing are used in mixing processes in which components of at least two separate components by
- Relative movement are repositioned so that a new arrangement scheme arises.
- a main phase is present as a continuous phase while a
- Aggregate state the phases are present in the mixing process of homogenizing, suspending, emulsifying or gassing.
- Homogenizing is understood to mean the mixing of gases or liquids which are soluble in one another.
- Suspending is the distribution of solid particles in liquids.
- Emulsifying is the distribution of liquid droplets in liquids.
- gassing gas bubbles are distributed in liquids.
- Arrangements for mixing media are, for example, from
- a particularly suitable method of circulating fluid volumes is to use immersion tube agitators having a motor that drives a propeller, with the engine fully immersed in the fluid.
- Immersion tube agitators cause a distribution of dirt, gases or other substances in a tank by the propeller hydraulics very large momentum forces are transmitted at low energy input and thus the
- DE 10 2010 014 239 A1 describes a device for mixing a medium.
- the assembly is positioned in a biogas production basin and includes agitators having a propeller driven by a motor that is completely submerged in the liquid.
- JP S58-24327A describes a shape memory element stirring device which is driven by a temperature gradient of a medium.
- the object of the invention is to provide an arrangement for mixing, which can operate largely independently of conventional energy sources. Furthermore, a method for mixing a medium to be specified, which are operated without a complex infrastructure or without a long supply line can. Also, the arrangement for mixing by a long life, a reliable operation and the lowest possible acquisition or
- the drive has a material for performing a thermal change of its geometric dimension.
- the material expands or contracts. Due to the thermal expansion or heat shrinkage changes the length, the surface area or the volume of the body, which is made of this material.
- the material is associated with the element in such a way that the changes in the geometric dimensions of the material cause a change in shape of the element. This change in shape of the element leads to the mixing of the medium.
- the material is a shape memory alloy.
- Shape memory alloys (abbreviation: SMA) are special metals that can exist in two different crystal structures. They are often referred to as memory metals. This is due to the phenomenon that they seem to be pronounced of an earlier shaping despite subsequent severe deformation.
- a nickel-titanium alloy is used as the material. These are characterized by particularly large effects combined with high strength. at
- the drive also has a material for oxidation.
- this is a catalytic material, wherein in particular a platinum-containing material is suitable.
- nanoparticles of platinum are used. These are applied in a particularly preferred embodiment of the invention on tiny tubes made of carbon.
- the material comes into contact with at least one substance which is reacted with oxygen in a catalytic reaction.
- the substances may be, for example, hydrogen or organic compounds such as methanol.
- organic compounds which are dissolved in the water are used as substances. This may be, for example, sugar or
- Carbohydrates such as starch act. Polluted waters, in particular, often have a large number of organic substances which are suitable as substances for oxidative conversion.
- the exothermic oxidative reaction releases heat which is transferred to the material to effect a thermal change.
- the material responsible for the oxidation is arranged around the material, which is a thermal
- the material for thermal modification may be rod-like, preferably in the form of a cylinder.
- the catalyst material is then arranged around this rod-like body, this preferably forming a hollow-cylindrical body.
- annular catalyst shell exhausts the exothermic oxidation reaction and transfers the heat to the inner core, which is a change in length due to the
- the element consists at least partially of an elastic material.
- a rubber-elastic material is suitable.
- the element may consist of a
- Silicone rubber or a silicone elastomer consist.
- the element is elastically deformable.
- the element has a crescent-shaped cross section.
- the element is preferably formed as a bell-shaped body.
- the connecting element may be a wire attached to the element and, in the event of a contraction of a material of the drive, deform the element in one direction, so that medium is conveyed.
- the connecting element is arranged at least partially in the element.
- a connecting element formed as a wire can be embedded in the elastic mass of which the element consists.
- a thermal change of a material of the drive which leads to a change in shape of the element.
- the return element ensures that the element returns to its original position.
- the restoring element can be, for example, a spring element which acts as a return spring, in particular a leaf spring element.
- the return element is integrated into the element.
- a return spring may be embedded in the element made of an elastic mass.
- the drive is fixed in place at one end. At the other end, the drive is connected to the element via a connecting element. As a result of the contraction and expansion processes in the drive, this creates a
- the drive is arranged in a space that is closed off from the medium to be mixed.
- the space has an inlet through which the educts for the oxidation of the
- Inflow catalyst material The material undergoes catalytic oxidation. This can be a total oxidation with the products water or
- a stream of the resulting products and the unreacted educts leaves the room through an outlet.
- FIG. 1 shows an arrangement for mixing with a contracted drive
- FIG. 1 shows an arrangement for the mixing of a medium.
- the arrangement comprises an element 1.
- the element 1 is designed in the embodiment as a bell-shaped silicone shell and has a crescent-shaped cross-section.
- the element 1 is connected to a drive via a connecting element 3.
- the connecting element 3 in the exemplary embodiment is a wire which is embedded in the element 1 and is connected to the drive by means of deflection rollers 4.
- the drive comprises a first material 5, which is designed as an inner core in the form of a cylinder and a second material 6 as an outer shell, which surrounds the first material 5 in an annular manner.
- the rod-like core of the drive 2 is a material 5 for
- a shape memory material is used, which is designed as a nickel-titanium alloy.
- the annular outer shell of the drive 2 is made of a material 6, which serves as a catalyst for an oxidation reaction.
- a platinum-containing material is used. These are carbon nanotubes coated with platinum particles.
- the oxidizing agent is oxygen or air and the substance to be oxidized is hydrogen.
- the space 8 is separated from a housing 9 by the space 10 in which the medium to be mixed is located.
- the oxidizing agent is reacted with the oxidizing agent on the catalytic material 6.
- hydrogen and oxygen react to form water.
- the mixture with the reaction products and the unreacted starting materials leaves the space 8 through an outlet in the direction of the lower block arrow.
- the Drive branch is transmitted.
- the material 5 heats up and changes its geometric dimensions. For example, there may be a length contraction, so that the rod-like drive 2 contracts.
- the wire-like connecting element 3 is tensioned so that the flanks of the bell-shaped element 1 are deformed upwards.
- the position is shown in FIG. In the deformation of the element 1 medium is set in motion and there is a mixing instead.
- the oxidation reaction ends on the material 6.
- the reaction comes to a standstill, for example, because no new oxidizing agent is supplied more or was already consumed in the space 8.
- the rod-like drive 2 cools down. For example, this leads to a change in length, as a result of which the wire-like connecting element 3 loses its mechanical tension and the flanks or wings of the bell-shaped element 1 again fold down into the starting position illustrated in FIG.
- the wire-like connecting element 3 loses its mechanical tension and the flanks or wings of the bell-shaped element 1 again fold down into the starting position illustrated in FIG.
