Definitions
- the invention relates to a vertical screw press for depositing solids, e.g. from fibrous sludges, for example from deingking plants or fibers from a pulp suspension, for example pulp suspension, with a cylindrical sieve basket and a press screw rotatably mounted in the sieve basket via a drive with a central worm shaft and arranged thereon, preferably at least over a large part of the worm shaft , Schneckenwendel, wherein a feed for the suspension, a drain for filtrate and a discharge for the dewatered solid are provided.
- a vertical screw press for depositing solids, e.g. from fibrous sludges, for example from deingking plants or fibers from a pulp suspension, for example pulp suspension
- Suspensions in particular pulp suspensions, for example pulp suspensions from the pulp and paper industry, which contain fibers, are generally dewatered and the solid constituents are compacted.
- pulp suspensions for example pulp suspensions from the pulp and paper industry, which contain fibers
- solid constituents are compacted.
- screw presses can dehydrate and transport suspensions efficiently only from a minimum content of about 8 to 10% fibers.
- the double bearing required for the screw press or worm shaft is disadvantageous and costly.
- helical or vertically oriented screw presses e.g. from the
- the object of the invention is therefore to provide a screw press with a vertical axis, which has a high efficiency in throughput and drainage and easy in blockages, i. in a short time, to clean.
- the invention is therefore characterized in that the cylindrical strainer basket is surrounded by a Filtratschreibstau interchangeer, seen in the axial direction consists of several parts and at least a part, preferably the lowermost part, a Filtratschreibstau practicer having a larger diameter, wherein the rotatable screw shaft can be made reversible , wherein the feed for the suspension at the upper end and the discharge of the dewatered solids at the lower end, whereby the conveying direction of the screw press from top to bottom and wherein a drain for filtrate at the lower end of the Filtratschreibstau interchangeers is provided and wherein the Filtratschreibstau electer with larger diameter vertically, that can be designed to be displaceable in the axial direction.
- a Filtratschreibstau interchangeer larger diameter and in particular displaceable design can be in a simple way the
- a favorable development of the invention is characterized in that the
- Filtrat Wegstau meanser in particular the parts of the Filtratschreibstau variousers, are divisible in the axial direction, i. consist of at least two parts. This allows the space around the worm shaft and worm helix to be opened in a simple manner.
- An advantageous embodiment of the invention is characterized in that a dilution chamber is provided at the upper end of the Filtrat Wegstau organizationsers, wherein the
- Dilution chamber may have at least one outlet opening.
- the dilution at the inlet for example, in a blockage, a resolution of the plug can be achieved and the dilute suspension via the outlet opening (s) are dissipated.
- Worm shaft openings for example a perforation, on at least one
- a favorable embodiment of the invention is characterized in that the lower end of the worm shaft is not stored in the radial direction or free of bearings and / or that the worm shaft exclusively at its upper end, in particular bearing in
- the plug can be at the bottom of the dehydrated solid, e.g. Pulp.
- Helix spiral serve as a kind of radial bearing.
- FIG. 1 is a view of a screw press according to the invention
- Fig. 3 shows a section through a screw press according to the invention in the operating
- Cleaning state analogous to FIG. 2, 4 shows a cross section through an inventive screw press along line IV-IV in Fig. 2,
- FIG. 5 shows a cross section through an inventive screw press along line V-V in Fig. 2,
- FIG. 6 shows a cross section through an inventive screw press along line VI-VI in Fig. 2,
- Fig. 7, 7a, 7b, 7c, 7d illustrates the pressure profile over a screw press according to the invention.
- Fig. 1 shows a vertical screw press 1 according to the invention which has a drive 2 at its upper end. Furthermore Filtratschreibstau electer 3, 4, 5 can be seen with a Filtratablauf 6 and at the bottom of a discharge 7 for the dewatered solid (pulp or sludge). At the upper end of the inlet 8 for the (pulp) suspension can be seen. It can also summarized the Filtratschreibstau electer 3 and 4 and consist of one piece, depending on the size of the screw press. It is important, however, that the lowest
- Filtrat Wegstau aser 5 is formed separately. Also can be seen arranged at the upper end dilution chamber 14 and the corresponding outlet opening 15th
- Fig. 2 shows a longitudinal section through a screw press 1 according to the invention along line II-II in Fig. 1.
- the same parts are provided with the same reference numerals. It can be seen again the Filtrat Wegstau essenceer 3, 4 and 5 and the discharge 7 for the
- Fiber suspension with pulp fibers through the inlet 8 at the top in the vertical arranged screw press 1 introduced. It is guided by the annular gap formed between the worm shaft 12 and screen basket 9, 10, 11 by the spiral screw 13 down and compressed by the decreasing slope, whereby the liquid (usually water) is pressed out of the fiber composite.
- the liquid usually water
- Fig. 4 shows a section through the screw press 1 according to the invention according to line
- Fig. 5 shows a section through the screw press 1 according to the invention according to line
- FIG. 7 shows a screw press 1 in which the pressure curve over the height of
- Screw press 1 in the drainage on the screen basket 9, 10, 11 is shown.
- a filling with filtrate and the resulting pressure is shown practically over the entire height.
- a lower filtrate height can also be set.
- the diagram in Fig. 7a shows the increasing hydrostatic pressure of the suspension
- the diagram subsequent thereto Fig. 7b shows the correspondingly increasing hydrostatic pressure of the filtrate, which builds up within the filtrate backhoe containers 3, 4, 5.
- This is possible in particular by the vertical arrangement of the screw press 1.
- Dewatering properties of the dehydrated solid is the height of the dehydrated solid
- Worm shaft also be conical, so that the gap between
- Worm shaft and screen basket in the conveying direction of the screw spiral reduced and thus the dewatering pressure is increased.
- the worm shaft can be radially mounted at its lower end, for example at low Austrags consistencies, as well as at higher
