Patented in the German Empire on September 26, 1813.

The present continuously acting centrifuge has the purpose, namely centrifugal material, of Components have different specific gravity, subject to comprehensive treatment to be able to.

As an exemplary embodiment, a centrifuge is used for: separating liquid parts from a liquid mass selected with drying of the solid residue, namely shows:

Fig. Ι the vertical section, Fig. 2 is a horizontal section along line 1-2, Fig. 1; Figures 3 to 6 show some variations of the partitions, and Figures 7 and 8 show details.

In this centrifuge, a conical, uninterrupted jacket B is arranged between the two plates B ² B ³ rotatable by means of a hollow shaft JV. The upper plate B ² bears the distributor M, the number of which depends on the number of secondary parts and outlet openings under which one works, especially on the liquid, steam or gas which is used in the treatment. The distributor M is connected to the container formed by the jacket B and the plates B ² B ³ , so that it can be connected to the same or. rotates with hollow shaft JV.

The plate B ³ is provided with openings B ^ through which the thrown off liquid can escape.

In the interior of the container formed from the jacket B divisions A, Fig are. Ι and 2, arranged in a suitable number, of towards the middle of the apparatus radially running vertical partitions are formed, which to the intermediate B ² B ³ plates A ^[A lying ² join.

The departments A have inside two filter surfaces C, which are inclined towards each other (Fig. 1) and each of which starts from the inner end of the partition walls and ends at a closed, endless end wall T which runs around rollers a (Fig. 2 and 8). These sections form the drum, which is arranged by means of the plate A ² on the inner shaft JV ¹ , the speed of which is different from that of the outer hollow shaft JV.

The flexible end wall T rotates with the drum and at the same speed. The same sits on the bolts 0 of Kettenil ¹ E ² (Gall's or Vaucanson chains), the links of which engage in the ring gears D ¹ D ² (Fig. 1) of the plates A ¹ A ² . The chains E ¹ and E ² have a guide roller between each link, and the vertical pins 0 (Fig. 2) are common to both chains.

The rollers α are arranged in such a way that an outlet opening b for the material to be treated remains between them. The chains are kept in the necessary tension by means of the rollers.

A third chain E ³ can be provided, the links of which ^{carry the axes of guide rollers G 3} and G * (FIGS. 1 and 7), which run on a track H, which is mounted inside the conical shell B and on a track H mounted on the outside ¹ roll. Likewise, the two chains E ¹ E ² are guided during their movement on the outside of the container in that their rollers run in a channel J ¹ J ^{2 provided} in the plates B ² B ^{3 of} the container.

For the transmission of a differential movement, according to FIG. 1, a worm wheel r set in rotation by a worm s by means of a pawl t is used. Other precautions can also be taken to generate a differential movement of the two shafts NN ¹ , so that details of the precaution shown in FIG. 1 need not be discussed. The operation of the centrifuge is as follows: If one of the compartments A comes in front of an opening in the distributor M, it picks up the goods to be treated. The amount supplied for each division depends on the difference in the speed of rotation of the distributor and that of the parts forming the drum, and each division receives from the distributor the liquid or gaseous mass, depending on the treatment to be carried out.

The centrifugal force acting on the material introduced into each compartment urges the solid part of this mass against the closing wall T, while the liquid particles are driven through the filter surfaces C. The liquid passing through this enters the space closed by jacket B and from here enters one of the chambers of the fixed basin P. As it moves, the compartment then reaches opening b, which is formed between the end walls 7 \, and then enters from the compartment the solid or dry particles into the basin P , from which they are removed by suitable means.

With further rotation, the relevant section is closed again by the second circumferential closing wall T and this process takes place in all other sections.

The filter surfaces C in the individual departments can be different depending on the type of work to be carried out in terms of design and arrangement. For certain purposes, the closing wall 7 ″ can also be designed like a sieve.

FIGS. 3 and 4 show, for example, filter surfaces which instead of simply, as in FIG. 1, are made twice. According to Fig. 4, the filter area is increased by the fact that the filter walls are bent on the outside.

For the purpose of separating certain substances, an open chamber can be formed from solid walls i in each division (Figs. 5 and 6), into which the more solid particles are introduced as a result of the centrifugal force, while the more fluid particles can escape through the filter surfaces C.

Claims (1)

Patent Claims: A continuously acting centrifuge with differential movement, in which the sections (A) of the rotating drum are formed by vertical, radial partition walls, which are closed in pairs by inclined filter surfaces (C) and a peripheral wall (T) . The design of the end wall T is such that it is carried by endless chains and runs around rollers in accordance with the movement of the drum, whereby the compartments (A) are alternately closed and opened during the treatment of the material. The connection of the sections with vertical full walls and those referred to in 1 inclined filter surfaces existing drum with a container with two or more openings is provided, on the sides of which the rollers leading to the endless end walls are arranged are such that the dry or solid material can escape from these openings. 1 sheet of drawings.
