The material from which the water or other liquid is to be removed is introduced into the device 1 between the opposing surfaces of the rotor 10 and the stator plates 8 and 9 through a feed hopper 38 which is attached to the stator housing 5 by means of bolts 39 or the like is attached into the feed gaps 44 in the stator plates 8 and 9. Attached to the lower end of the feeder tube 38 is a disc-shaped scraper 41 made of a material such as Eeflon and preferably having an inner surface 42 curved to match the curvature of the outer periphery of the rotor 10 so that it fits directly therewith Surface Iv may have a single grip to prevent material from being drawn around the outer circumference of the rotor.

In FIGS. 5 and 8 and additionally in FIGS. 9 to 11 the rotor 10 is shown with the same spiral-shaped ribs or plate bands 45 on opposite sides Sides that converge towards the center of the rotor and the stator plates 8 and 9 have similar helical ribs 46 that oppose theirs converge towards respective centers, but in one direction opposite to that of the helical ribs 45 on the Rotor are inclined. Accordingly, when the rotor 10 is driven clockwise as shown in Fig. 5, for example is driven, the material in the feed hopper 38 through the ribs 45 »46 radially inwardly. When pockets 47 and 48 between the ribs 45 and 46 on the rotor 10 and the stator plates 8, 9 are once filled with material, so that Material in a wedge shape between the ribs 45, 46, which move relative to one another, towards the central openings 47

In recent years, various "types of centripetal extrusion devices have been developed which operate with the centripetal force that arises when a vieco-elastic material is introduced near the periphery of two flat relatively moving plates around the material radially inwardly through a central ejection opening and mold. However, if water or some other such liquid is present in the material, the liquid acts as a lubricant and prevents softening and smearing. shaped ribs 45 "46 are mounted on the rotor and the stator to force the material against the center of the device to move back. During such inward movement of the material total weight ammenge squeezes · is. and torn, so that it releases the water contained therein * Since the water is not viscous, it becomes radial due to centrifugal force which occurs during rotation of the rotor 10, which may range from 0 to 250 rpm (rpms); however, the rotor is preferably operated at a rotational speed between 100 and 200 rpm (rpms) . A band 50, on the underside of which a seal or a sealing ring 51 is attached, surrounds the rotor 10, its edges sealingly resting on the outer circumference of the stator plates 8 and 9 in the radial direction outside the circumference of the rotor 10 (see in particular the figures 5 to 8), so that the water can only exit through the openings 52 in the bottom of the stator housing 5. One end of the band 50 is screwed to the feed funnel 38, while the other end is preferably with split pins

909820/08 6 8

is attached to the stator housing 5.

In contrast to the outward movement of the Water is the viscous elastomeric or polymeric material, causing it to resist centrifugal force through the ribs the rotor and the stator plates is forced to move radially inward, where it is passed through the discharge nozzle 26 via material discharge chutes 54 at opposite ends the discharge screw is removed.

The material becomes dehydrated during the dehydration process not extruded, and no melting of the material is required or even intentionally. There is also no noticeable change in the viscosity of the material. While of the material processing process, however, a certain amount of heat is generated, which can be dissipated by the fact that Circulating coolant through annular chambers 55 in the end walls 6 and the stator housing ^ e as needed. water gum containing e.g. If the device emerges, it has the appearance of crepe rubber, that is, the rubber crumbs stick together in the form of a tube.

The size of the discharge openings 57 through which the material passes, if it can the stator reaches 8 and 9 of the discharge screw 26 from between the rotor 10 and changed to the information carried by the device 1 at different rotor speeds of _v, To vary the amount of material so as to ensure effective operation of the device in which all water is removed from the material. Such a change in the discharge openings can be carried out in that the throttle sleeves 56 are axially adjusted or displaced. How best from Pig. 8, the throttle sleeves 56 are pushed over the ends of the discharge screw 26

909820/08 6 8

or arranged and atehen in thread-like engagement with Sohrauben 57 on the band walls 6 and 7 of the stator housing are attached so that by rotating the throttle sleeves 56 in the desired direction ine or outward movement of the throttle sleeves in the axial direction is caused.

The mechanism 58 for rotating one of the throttle sleeves 56 is shown in detail in Figures 3-4 and 8, and the mechanism for rotating the other throttle milse is hereby identical. The mechanism 58 includes a cylinder 60, the inner end of which is on the adjacent end wall 6 of the stator housing is screwed and the outer end of a Attachment arm 61 attached to the frame 2 is carried is. In the cylinder 60, a piston 62 is arranged, which with the throttle sleeve lever 63 by an adjustable Connection 64 is coupled. The piston 62 also has a threaded rod 65 extending from the end of the joint 64 is opposite, protrudes and into the bore 66 a sleeve 67 is screwed, which is rotatable in the cylinder 60 by means of a handle 68 which is attached to the outer End of the sleeve is attached. By turning the handle 68 and associated sleeve 67 will, as can be readily seen, move axially inward or outward of the piston 62 causes a rotary movement of the throttle sleeve lever 63 and the throttle sleeve 56 results.

Although only a single dewatering device 1 for explanation is shown, it is understood that several such devices are arranged side by side and possibly operated by a single drive motor can be. In addition, various modifications in the structure of the rotor and the stator can be considered. For example, instead of having a single rotor in the middle
