Definitions

  • the invention relates to a method for mixing according to the preamble of claim 1 and a mixing device therefor according to the preamble of claim 6.
  • the object of the present invention is therefore a method for mixing and an associated Mischvor ⁇ direction to create, at 'the faster a lot with relatively simple means compared to the prior art and more uniform complete mixing can be brought about without dead zone.
  • the invention achieves a remarkable technical advance in an astonishing way.
  • Exact investigations have shown that in conventional solid mixers due to the uniform or regularly recurring mixing movement with the sometimes very different particle properties which are to be mixed and which differ from one another for example in terms of their size, their shape or their density cannot produce an ideal, uniform mixture, but rather that there is always a tendency towards segregation.
  • Such a regular mixing movement can cause, for example, an increase in gravity in a solid stream;
  • high Froude numbers which can mean a centrifugal movement of the mix, wind sifting can also occur, etc.
  • the Froude numbers are the ratio of the centrifugal force (centrifugal force) to the gravity of the mixture.
  • the method according to the invention and the associated mixing device according to the invention are characterized above all by the fact that no uniform and repetitive motion sequences are used. Rather, when mixing, care is taken to ensure that the angle of the mixing container to the mixer axis changes irregularly during rotation of the mixing container about its axis of rotation or mixer shaft, i. is constantly set differently, so that a stochastic random distribution is given. In a further development, the speed, i.e. the speed of rotation and also the direction of rotation are constantly and irregularly adjusted so that a stochastic, randomly distributed control is also provided.
  • the control system thus includes a random generator.
  • Grinding media can also be added to the mixing vessel of the stochastically operating mixing device. This creates a stochastically controlled mill. Although different shapes are possible, spherical or cylindrical grinding media are particularly suitable. Due to the different Froude numbers, the solid is crushed both by the friction and by the impact. It ⁇ * becomes z. B. with a small Froude number, the blowing away of the fine fraction observed in vibrating ball mills before the impact of the grinding media is avoided. On the other hand, with a higher Froude number, coarse-grained regrind is broken up by impact. The stochastic control thus captures a broader grain spectrum during comminution.
  • the stochastically controlled tumbling movement of the mixing container can also be used for washing machines.
  • the device is also used, at least in those cases in which, as in the case of the textile parts in the washing drum, processing is to take place with a constantly changing Froude number.
  • the mixing vessel is guided through the tub with corresponding stochastic control. Relative accelerations occur constantly between the textiles and the lye, which wash the dirt out of the fabric so intensively and quickly.
  • a "unstable mixing tool” is already known, which is constructed in the manner of a stirrer.
  • This mixer works with a rotatably mounted stirrer, on which blades are usually attached. These blades should be adjustable in their angle of attack during rotation, the size of the angle of attack being subjected to a random control.
  • This randomly controlled stochastic change in the angle of attack of the vanes on the rotor similar to a propeller with rotor blades which can be changed in their angle of attack, but essentially serves only for stirring liquids. But when stirring powdery substances, the entire stirring and mixing process is comparable to that of liquids, since a fluidized flow behavior is also given when stirring substances containing powder or solid particles.
  • FIG. 2 a schematic top view of the exemplary embodiment according to FIG. 2;
  • Figure 3 is a schematic representation of a modification to Figure 1.
  • FIG. 1 and 2 show, for example, a cylindrical mixing container 1 which is held over part of the fork suspension 5 forming the mixer shaft or axis of rotation 3 (but also a one-sided suspension for easier assembly and disassembly of the mixing container is possible).
  • the mixer shaft / axis of rotation 3 is driven by a drive 7 with a stochastically different distributor of rotational speed or rotational speed, with the rotation also being reversibly stochastically distributed.
  • a further drive 12 is provided in the region of the fork suspension 5 for the stochastically changed setting of the inclination angle 9.
  • the electrical control and power supply lines are laid inside the shafts and require slip-ring-like contacts at the corresponding points, for example between the mixer shaft / axis of rotation 3 and the correspondingly fixed drive 7 of this axis.
  • the mixer shaft / axis of rotation 3 could also be rotated by a further primary axis 13, which is angled to the mixer shaft / axis of rotation 3, in particular at a right angle, in order to achieve a further rotational movement in the sense of a third degree of freedom be, the arrangement similar to a cage can also be such that the extension of this third axis of rotation also extends the extended axis ⁇ ge ⁇ ra'de_ ⁇ J the mixer shaft / axis of rotation 3 and the container axis 6 in a common intersection, which preferably in the middle - or center of gravity of the mixing container 1 is.
  • Axis 13 can be stochastic, i.e. are driven with randomly distributed speed and direction of rotation, namely via a further drive 15.
  • the mixing container 1 should not be spherical or cube-shaped.
  • At least one boundary side of the mixing container can be designed in the form of a closable funnel 17.
  • This funnel 17 can be used when decanting the mixed material, so that segregation, as might occur when decanting the mixed material when using a separate funnel, is eliminated.
  • the material hopper of the processing machines is expediently used directly as a mixing vessel. After mixing, the material hopper must be placed on the processing machine free of vibrations.
  • FIGS. 1 to 3 can in principle also be used in washing machines, the mixing container 1 then forming the washing drum which is guided through the tub.

Abstract

Les procédés et les mélangeurs employés jusqu'à présent pour obtenir des mélanges homogènes posent, sur le plan pratique, de nombreux problèmes, dans la mesure où l'on observe constamment une tendance non négligeable à la dissociation du mélange. L'invention permet de pallier cet inconvénient en prévoyant un récipient mélangeur pouvant pivoter simultanément autour de deux axes de rotation (3, 6) au moins, avec deux degrés de liberté, de manière à améliorer la qualité du mélange. Par rapport aux techniques actuelles, on constate une amélioration surprenante et très nette du mélange, principalement dans le cas d'un entraînement stochastique, c'est-à-dire irrégulier et aléatoire, et en relation également avec le nombre de tours et le sens de rotation.
