Definitions
- the present invention relates to a screw press for separating liquid from, in particular, pressurized solid-liquid mixtures, in particular fiber suspensions, with a screw rotating in a jacket provided with liquid passages.
- the material In conventional screw presses, the material is discharged at the end of the screw, the material containing more or less liquid depending on the selected operating conditions, which is undesirable in many cases.
- the invention is primarily characterized in that the, preferably hollow, shaft of the worm has a smooth end region adjoining the region provided with at least one worm rib in the axial conveying direction, in which the worm shaft is a jacket shaft with a cavity between a shell and a preferably hollow one , Core is formed and that this jacket has liquid passages, for example bores, to the aforementioned cavity and this cavity is connected to at least one liquid drain.
- the worm shaft of the worm has a smooth end region adjoining the region provided with at least one worm rib in the axial conveying direction, in which the worm shaft is a jacket shaft with a cavity between a shell and a preferably hollow one , Core is formed and that this jacket has liquid passages, for example bores, to the aforementioned cavity and this cavity is connected to at least one liquid drain.
- a liquid drain is provided through liquid passages inwards into a cavity.
- the device according to the invention is advantageously used particularly in the dewatering of fiber-containing mixtures, such as, for example, fiber suspensions or municipal sludges, which are introduced into the housing and are subjected to a corresponding pressure by the screw.
- the cavity is expediently formed in the end region of the worm shaft between a core which tapers in the axial conveying direction, in particular a hollow core, and a hollow cylinder placed thereon and provided with liquid passages.
- the tapered end region of the worm shaft creates the largest possible cross section for the liquid to drain off.
- the core advantageously tapers in the end region of the worm shaft in the axial conveying direction. This facilitates production and drainage.
- the liquid passages are arranged in the end region of the shell of the screw shaft in the region of the conveyed goods retention. This allows good control of the fluid leakage.
- the liquid passages in the end region of the shell of the worm shaft preferably point towards the cavity between the shell and core of the worm shaft, i.e. in the outflow direction of the liquid, increasing cross section. This promotes fluid drainage.
- the jacket of the worm shaft there are provided in the end region on the jacket of the worm shaft, preferably arranged parallel to the longitudinal axis of the worm shaft and in axial planes, with the jacket and the core channels for deriving the Form liquid. This allows regulated liquid flows to be achieved.
- An overflow for the liquid is expediently provided at the end of the channels.
- flushing devices preferably spray nozzles, are provided at the end of the channels for cleaning the channels, in particular of entrained fibers.
- the screw shaft and also the tapered core connected to it are preferably hollow, which results in a favorable weight reduction of the screw press.
- FIG. 1 shows a longitudinal section through a screw press according to the invention
- FIG. 2 shows a longitudinal section in the end area of the screw press
- FIG. 3 shows a cross-sectional segment in the end area of the screw press along plane III-III of FIG. 2 in reduced form
- FIG Cross-sectional segment in the end region of the screw press along the plane IV-IV of FIG. 2.
- the same or corresponding parts are provided with the same reference numerals: there are 11 the inlet nozzle in the screw chamber, 3 the curved screen of the screw chamber and 4 the support body for the screen 3, 13 the screw shaft, 14 or 14 'worm ribs on the worm shaft, with 17 the tapered core of the worm shaft 13, with 19.19' partitions, with 21 retaining flaps, with 22 the jacket of the worm shaft, with 23 channels for draining the liquid and with 12 a shaft at the end of the Screw press to discharge the dewatered substance.
- FIG. 1 An overall illustration of the screw press according to the present invention is illustrated in FIG. 1.
- the pulp suspension to be dewatered is introduced into the screw chamber via the inlet nozzle 11.
- This chamber consists, for example, of a plurality of rows of circularly curved sieves 3 and support bodies 4, which form the cylinder jacket, and the screw ribs 14, 14 'are or are open a hollow worm shaft 13 attached.
- roller stubs 15 are mounted, by means of which the worm shaft 13 (together with the worm rib (s) 14, 14 ') is rotatably mounted in bearings 16.
- the dewatered material is finally discharged from the screw press through a shaft 12.
- the screw shaft 13 has a conically tapering core 17 in the end region of the screw press.
- the core 17, the partition walls 19, 19 'and the jacket 22 of the worm shaft or a sieving section 3' together form channels 23 for discharging the liquid.
- the liquid is discharged from the screw press via an overflow 18.
- rinsing devices 20 e.g. Spray nozzles, provided. This means that the ducts can also be cleaned during operation.
- Previously known versions of screw presses often had to be turned off for cleaning purposes and sometimes also disassembled.
- retaining flaps 21 which can be regulated by means of hydraulic cylinders are provided.
- FIG. 2 shows part of the end region of the screw press according to the invention in longitudinal section.
- partition walls 19 Parallel to the longitudinal axis of the worm shaft 13 and arranged in axial planes and attached to the jacket 22 of the worm shaft, partition walls 19 extend up to or almost to the core 17 of the conically tapering worm shaft 13.
- Core 17, partition walls 19, 19 'and jacket 22 or smooth end region 13 'and section 3' of the worm shaft form channels 23, from which the liquid with separation of solid matter after passage in the outflow direction 8 r through the sieving section 3 l or its ' openings 3' and through the cavity 13 "is derived from the screw press between the smooth end region 13 'or section 3' and the core 17.
- pressure can be exerted on the fiber suspension to be dewatered.
- FIG 3 shows a cross-sectional segment of the end region of the screw press with the individual channels 23 which are formed on the one hand by the walls of the core 17 and the screw shaft jacket 22 and on the other hand by the walls 19, 19 '.
- Fig. 4 shows a cross-sectional segment in the end region of the screw press with the retaining flaps 21 in the region of the smooth end portion 13 'of the screw shaft for regulating the back pressure or the conveying material retention, so that the material present in this region is exposed to increased pressure and still in the material existing liquid is squeezed out and flows through bores 3 "in the jacket of the worm shaft into the cavity 13" formed by the smooth end region 13 'and the tapered core 17 of the worm shaft.
