As is well known, the separation of mixtures of liquids and solids -by It is difficult to sieve if it is a material in which the solid substance makes the sieve easily clogged and clogged with a layer that is difficult to permeate. Such Separating solid bodies from liquids cannot be achieved by using one of the following: Shaking sieve, on the contrary, the latter leads to a more dense storage of the solid bodies settling on the sieve, like this. that thereby the permeability for the Liquid is reduced even more.

The inventor has now found that the Abandonment of decomposing such muddy ones; -origenic mixtures of solids and liquids can be solved economically and technically satisfactory, if one treats such mixtures on sieves, which execute a throwing motion, in which the solids on the inclined sieve surface move upwards.

Sieves with an inclined sieve surface and a throwing motion in which every point of the Siebes describes an arc of a circle are known per se.

They were used to treat dry, dusty or other foreign bodies Fabrics suggested. But it was not to be inferred from this that the use Such sieves would lead to the solution of the problem, which is pulpy Mixtures that are practically impossible to dewater at all, for example by pressing, such as B. Mixtures of meat meal and broth, as they fall in modern carcass disposal, or 'wet peat pulp, too disassemble.

The inventor has found that when treating such mixtures on one Litter sieve has very good drainage results as a result of the free storage and ■ movement on the sieve let reach.

However, the inventor has also found that it is necessary to use a throwing screen with sloping Use sieve and the movement of the material in such a way. cause it to jump wisely forced to wander upwards.

This prevents the watery parts from advancing, for example in the case of horizontal ones Seven by leading the solid. Overtake material and, as a result, over the sieve addition, z. B. would flood over into the dryer.

In the following, the treatment of the material is to be carried out using one shown in the sketch suitable sieve shape are explained.

The sieve α is carried by pairs of levers b, b ' which are moved by levers c, c' by means of a linkage d . The movement which the linkage d gives to the levers b, b ' or their end points is arcuate, so that the sieve α with the material lying on it is raised in an arc and is lowered backwards again in the same arc. As a result, the material is raised when the sieve is lowered, and since the movement takes place in a circular arc, the material falls down at a further forward point on the sieve, so that the material moves further with each lowering. As a result, there is a permanent relief of the sieve from that

material lying on it; it finds

- there is also a relocation of the material,

so that each setting the solid body on

the sieve is avoided and the liquid is allowed to drain easily.

With this arrangement the material migrates up the screen and the solid material becomes euomatic on the upper side of the sieve ejected. The liquid exits through the sieve and becomes more suitable Wise 'brought to derivation. A change in the sieve movement or an enlargement
