Separation device

The invention relates to a device for separating solids in a liquid solvent are suspended. The solid to be deposited is consequently in constant contact with the solvent, and so is the deposition is achieved through a directed and constant shift of the liquid solvent favors the solids to be separated from it »

A major advantage of this device is based on the ■ Fact that they are allowed to separate organic matter without that these substances are decomposed or killed during the treatment. The process is therefore particularly suitable for separating plants Substances such as fruits, spices, flavorings, etc. are suitable.

The device according to the invention is characterized in that it ate out of a container which receives the suspension

consists, has a cage arranged therein, the at least one immersed in the suspension chamber and also one second somewhat smaller chamber contains, ciie with a permeable one Wall is provided, and one rotatable in the small room arranged rotary or turbine body, which generates a liquid stream flowing through a cage.

In a preferred embodiment of the invention, there is a cage from two superimposed chambers which are connected to the suspension at their opposite ends, these chambers being connected by a core intermediate chamber are, which has a permeable wall and in which the movable Part is stored.

The drawing shows schematically an example of the embodiment of the device according to the invention, namely show

Fig. 1 is a view of the device in which the liquid container is shown in section, and

Fig. 2 shows the cage on a slightly larger scale and partially in vertical longitudinal section.

The device illustrated comprises a container 1 which is closed at the top by a cover 2 and parallel on its periphery two side walls 3i3 ^a, between which a heating or cooling medium to circulate. The cover 2 is provided with one or more filling openings 11 · and the bottom of the container with lines 5 and 6 for draining off the liquid and the solids separated therefrom. ■

The device is also provided according to FIG. 2 with a cage 7, which is formed by two superposed chambers 8 and 9 _o which are connected by an intermediate body 10 of smaller diameter. The upper chamber 8 is covered with a cap 11, which in turn is arranged tightly with a pipe socket 12 in the cover 2. The cap 11 is provided with a number of openings 13, and the cage 7 is provided with a releasable lock, for example with a screw or a bayonet socket; firmly attached and contains a sieve or a filter Ik, which is arranged between the upper edge of the cage .7 and the cap 11.

The wall of the intermediate body 10 is provided with passages IJ? which open into the container 1. The lower chamber 9 has a bottom ring 16 which holds a filter 17 arranged at the bottom of the chamber. Finally, the device has a turbine 18 at the lower end of a shaft. 19 sits, the XiV. Inside the pipe socket 12 is mounted and guided. The device is driven by an electric motor 20 indicated in FIG. 1. . '

In ß-atriebszustand the container 1 is sure we incorporated with the liquid to behanaelnaen _o which consists of a liquid solvent UNU a dispersed therein solid. The rotation of the turbine 18 causes a turbuj.e.iii. In the narrowed part of the cage 7, which drives the liquid through the holes 15 and causes a pressure inside the chambers 8 and 9, under which it takes effect the lack of two opposing currents

shows how this is indicated by arrows in the drawings is. These currents cause a constant displacement of the solvent with respect to the solids contained therein and promote their separation. The filters "J and 17, that the liquid subjected to the separation does not come into contact with the turbine, and the chambers 8 and 9 e only the solvent enriched with the excretions,

In a modified embodiment of the invention, oils can passages 15 wholly or partially open into a (not shown) Leicung which diverts the deposited solid from the container This line could also open into another part of the cage, with the separated mass e.g. Circulation is offset.

In a further modification of the device, the needs To have cage only a single chamber, which is adjacent to the narrowed central part in which the turbine is located. This part of the cage is closed by a floor in this case.
