Definitions
- the object of the invention is to improve the performance of existing mixers.
- the object of the invention is also to solve the new problem of dead zones in mixers. Indeed, if the mixer is not suitable for the container geometry, there are areas called dead zones, in which the middle remains at rest. In these areas, no mixing takes place. he is also possible that a mixed volume in such a dead zone will separate from new. This problem is particularly encountered for the lower corners of cylindrical containers for example. This problem of dead zones and uniformity of mixing is all the more sensitive when it comes to mixing a viscous medium or mix on low speed. In these cases, the effects of mixing are limited to the area swept by the mixing devices. We can then obtain a non-uniform mixture if the mixer is not suitable for the geometry of the container.
- the invention provides a solution to this problem of dead zones, in particular in the case of containers spherical.
- a first toothed wheel 11 is rotatably mounted around the first shaft, and is held fixed relative to the container 6 by a locking rod 12. In this way, the gear is fixed.
- a second toothed wheel 13 is fixed on the second shaft 2 and meshes on the first gear. The first and second gear wheels form a first gear.
- the device of the invention is suitable for the rapid and efficient mixing of liquid or solid materials, for example powders. We give below the results of mixing tests in an apparatus of the type of that of FIGS. 2 and 3, for a mixture of saccharin in milk powder or in flour.
- the operation of the mixer of FIG. 6 is as follows.
- the tree 80 or first shaft is rotated, and rotates around its axis.
- the tube transmission rotates at the same time around the axis of the first shaft.
- the shaft 76 or second shaft is rotated around the axis of the shaft 80 and of the transmission tube.
- the rotation of the first shaft 80 ensures the rotational drive of the second shaft around its own axis.
- the mixing bodies are rotated around an axis substantially horizontal, this axis itself being rotated in the middle.
- the present invention is not limited to the examples and methods of realization described and represented, but it is susceptible of numerous variants accessible to those skilled in the art.
- the invention is not limited to the preferred embodiment.
- the whole movement is transmitted to the different parts of the mixer, by the intermediary of the first tree; this solution has the advantage of allowing mount the mixer drive motor in a fixed position, which limits moving masses.
- We could also provide a first fixed shaft, and a motor driving the second tree.
- the trees are perpendicular; one could also foresee that the second tree is inclined relative to at the first tree, for example to increase the volume likely to be swept by the mixing organs.
