Definitions
- the present invention relates to a screening device for separating coarse materials from a suspension in accordance with the preamble of claim 1 and to a fabric batch device using the same with a screening device which has the shape of a truncated cone.
- Sieving units can be found in a wide variety of industries for a wide variety of applications. Screening units are very widespread in processing technology, where they are used for sorting flowable substances containing solids of different sizes. An important application is the so-called pulpless pulper, which is used to prepare mixtures of substances that contain easily friable components. Important areas of application are in the treatment of waste and waste-like substances as well as in the paper industry in the treatment of waste paper.
- Such a pulper consists of a container provided with a rotor. In operation, this is prepared ting mixture of substances entered in the container and also a liquid, generally water, m filled the container. The rotor is rotated and thereby generates strong flow forces. Seen in an axial section through the pulper, this flow has a toroidal shape, with two main flow components overlapping, namely a radial and a concentric flow direction. In the rotor area this flow is initially formed radially outwards against the container wall, it then rises upwards in order to
- a preferred application is, for example, the processing of waste paper or the processing of waste for the biological recycling of individual components.
- the components that can be recycled biologically are separated from the components that cannot be recycled biologically. Because the bio-usable components are easily shredded, compared to the other components that are difficult or not shrinkable.
- the suspension produced and separated by the perforated sieve, in which the biologically usable constituents are concentrated, can then be sent for biological utilization, while the biologically non-usable constituents, i.e. the coarse substances that remain in the pulper after the suspension has been drawn off, are separated and one other appropriate forms of recycling can be disposed of or disposed of.
- Other screens previously used in conjunction with pulps for separating the coarse matter from the suspension are either in the form of a flat screen (for example EP 0 520 172 Bl or DE 195 06 084 AI) or as a cylindrical screen (for example EP 0 598 187 Bl).
- the use of a cylindrical vertical screen leads to other disadvantages.
- the suspension is drawn off through the vertically positioned sieve parts.
- the non-defibrated coarse material tends to collect around the sieve at the pulperooden and thus block the passage of the sieve.
- the flow behavior in the pulper is unsuitable, a satisfactory one Moving the coarse material and thus cleaning the screen surface to bring about, since the flow does not touch the vertical parts of the screen.
- the sieve can only be cleaned by additional measures, generally through the use of room strips.
- the coarse materials that accumulate around the sieve on the pulper base also contribute to increased wear.
- the use of room strips also leads to a further significant disadvantage in that the room strips greatly reduce the plastic components present in the waste. These small plastic particles can then pass through the perforated sieve with the suspension. In this way, they contaminate the suspension intended for biological recycling and thus also lead to an undesirable degree of contamination of the end products, especially the compost and the process water.
- the object of the present invention is to improve the fabric batch device defined at the outset for separating coarse materials from a suspension in such a way that wear is reduced, clearance and maintenance of the screen are facilitated, the flow of the suspension is accelerated and the product quality is improved.
- a sieve device which has the shape of a truncated cone.
- the truncated cone points upwards with its smaller circular area.
- the sieve openings are arranged on the inclined surface of the truncated cone.
- the slope is designed so that it lies approximately tangentially or parallel to the toroidal flow.
- the screening device is segmented and attachable from the outside.
- the inclination or inclination is preferably 30 ° -50 °, this value being able to vary depending on the shape of the container.
- the oblique arrangement has the consequence that the flow acts steadily so that the coarse substances sinking in the pulper are removed from the surface of the screen, that is to say they are carried away by the flow.
- This process is further promoted by the use of scrapers, which, however, are subject to a lower load than in the prior art. This is because cleaning does not take place exclusively via the room strips, as in the case of the flat sieves or cylindrical sieves shown, but to a considerable extent via the flow.
- the abrasion caused by sand, pebbles, glass etc. also becomes significant - lent reduced.
- the better cleaning of the sieve surface also favors the flow through the sieve and thus reduces the withdrawal time of the suspension.
- the sieve openings can be designed differently, e.g. be square, circular or elongated. Their characteristic dimensions are preferably 6-30 mm.
- the screen is preferably divided into segments to facilitate its removal.
- the wipers used to support the cleaning of the sieve punches from coarse dirt are preferably attached to the rotor or its shaft and can also have a wide variety of designs. You can e.g. be straight or oblique.
- the wipers are preferably continuously or discontinuously curved to prevent flow and are equipped with a wear strip.
- the wear strip is preferably interchangeable and / or adjustable.
- a pump is preferably used, the drive of which is adjustable, but a free drain into a lower-lying storage container is also possible.
- the invention is particularly suitable for use within the
- waste mixtures with a high proportion of organs such as municipal bio-waste
- organs such as municipal bio-waste
- biogenic-organic components that are suitable for biological treatment and subsequent recycling into the natural cycle, due to a relevant proportion of non-biogenic organic substances such as plastics, stones, glass and metals.
- FIGS. 1 a to 1 c show a schematic illustration of an embodiment of the screening device according to the invention, namely FIG. 1 a in cross section, FIG. 1 b in section along the line AA 'of FIG. 1 a and 1 c an enlarged detail of the area designated Z. .
- the waste mixture is fed to the cylindrical pulper container 1 with the addition of water.
- I denotes the waste supply line and II the water supply line.
- the waste water mixture is set in motion by rotations of the rotor 2 about the container axis R.
- a strong toroidal flow 3 is generated, which leads to the biogen-organic, non-woody components of the waste being fiberized.
- These fibers form a suspension with the liquid present in the pulper, which is drawn off through the frustoconical perforated sieve 4 located in the lower part of the pulper and flows out of the outlet III, to which a pump (not shown) can be connected.
- the non-organic gen-orgamschen un ⁇ the woody components of the waste, which remain largely undestroyed by the flow forces, ie the coarse materials.
- the suspension produced and separated by the perforated sieve, in which the biologically usable constituents are concentrated, can then be sent for biological utilization, while the biologically non-usable constituents, i.e. the coarse substances that remain in the pulper after the suspension has been drawn off, are appropriate to another Form of recovery or other disposal can be supplied.
- the embodiment of the screening device 4 according to the invention described here has the shape of a truncated cone.
- Sieve openings are located on the lateral surface 5 of the truncated cone, are round and have a diameter of typically 10 mm.
- the inclination of the outer screen surface is approximately 30 ° to 50 ° with respect to the axis of rotation R.
- wipers 6 are fastened to the rotor 2 or the rotor shaft and are curved in an arc-shaped manner to prevent flow.
- the front of the wipers 6 is protected by an exchangeable and adjustable wear plate 6a.
- the sieve segments of the sieve 4 are fastened to the webs 9 with screws 8 from the outside of the container such that they can be removed from the inner side of the container when the screws 8 are loosened.
