Definitions
- the invention relates to a wing and an arrangement of several wings for sorting devices, in particular are intended for fiber suspensions in paper pulping.
- the invention relates to preferred wing shapes.
- a wing or a Sorting wing of a sorter with a drum-like body known.
- the wing points in the direction of rotation ever increasing cross section and ends in one steep edge, and this is included in the direction of rotation Extension with a decreasing cross-section with a Fillet.
- the area with increasing cross section forms in Interaction with a surrounding the drum-like body Sieve wall a suction zone, and the area with decreasing Cross section forms in cooperation with the screen wall Pressure zone.
- the outer contour of the wing includes a steep one falling edge at the transition between the area with increasing Cross section and the area with decreasing cross section.
- WO90 / 05807 and US-A-2 835 173 are sorting devices known, which have a rotor that on its outer circumference Cleaning elements or sorting elements is occupied.
- the above installation of the same can also be fiber bundles and braids as well as dead zones and spinning due to the Form the disruptive effect of the cleaning elements in the material flow area.
- the Annular gap between the screen wall and the rotor base body due to the projecting height of the cleaning elements or Driving elements narrowed. If between the highest point of the Cleaning element and the sieve wall surface only a small one If there is a distance, the goods to be treated can be on this very narrowed, annular gap a very strong Experience thickening. This leads to malfunctions of the Sorter. However, if you arrange such a rotor at a greater distance from the screen wall, so you have to Increase the speed of the rotor, reducing the energy consumption of the Sorting device becomes larger.
- the invention aims to achieve the one outlined above Need to take into account and especially while overcoming of the difficulties described above wings for sorting devices to provide, especially for fiber suspensions are determined when digesting paper and which in supportive An efficient and reliable manner high quality sorting with an energy saving Allow operation.
- a wing for sorting device especially for fiber suspensions in paper pulping, provided which faces such a screen wall Outside contour has that in cooperation with the screen wall in Flow direction a suction zone section with increasing Wing width and a pressure zone section with decreasing Wing width forms, whereby the total length of the wing the length of the suction zone section and the length of the pressure zone section composed.
- the wing according to the invention thus has to face the screen Outside contour profiling without edges, breaks or Fillets, but with both the section of the wing increasing wing width as well as the section of the wing decreasing wing width and also the transition area a steady course. This is also in the area of the pressure zone section a steady increase in pressure due to the steady course available, which ensures gentle transport of material to the perforations the screen wall takes place. This prevents Contamination in the pressure zone section due to the perforations the screen wall to be pressed. So you get an improved one Sorting quality. At the same time, you also get the necessary ones Turbulence to keep and clean the perforations as well sufficient fluidization of the goods to be sorted due to the change in sash width in the suction zone section.
- the sorting device especially suitable for sorting tasks in High consistency area, as well as for sorting tasks with quite coarse impurities, since the sorting quality can significantly improve.
- the total length Fl des are further influencing variables Wing, based on the inside diameter of the screen, as well as the largest Wing width Fb to mention.
- the total length Fl based on the Sieve inner diameter Di, is about the order of 0.05 to 0.3 x Di, preferably from 0.08 to 0.2 x Di.
- the order of magnitude for the influencing variables of the wing in the Suction zone section has such a sufficient length that reliable cleaning of the perforations of the screen wall is guaranteed. If the suction zone section is too short, the current breaks off too soon and turbulence occurs, which affect the cleaning effect.
- the smallest distance s between the Outer contour of the wing and the sieve wall about 0.5 to 10 mm, preferably 1.5 to 6 mm.
- Such a distance is essential smaller than with conventional designs of such sorters, so that you can get very high quality sorting results without Can cause malfunctions.
- the rotor speed can also be changed lower because the wings are reduced due to the Distance very effectively with regard to the fabric flow area the cleaning and fabric management act.
- the sorting device works, it can be turned away from the screen Page designed so that they are essentially with the shape of the screen-facing outer contour according to the the above explanations. You then get one symmetrical design of the wing.
- the screen facing away Side of the wing deviates from the screen facing Be designed outer contour.
- the one facing away from the screen Side be formed as a straight section.
- the wing is aerodynamically profiled. This can reduce the wing's inherent flow resistance and the energy consumption can continue to reduce. This also allows interference flows in the Suppress fabric flow area to reduce the fabric flow both on the Favor cleaning side as well as on the fabric feed side.
- the wing can be designed in several parts. If he Wing is designed in one piece or in several parts, depends on essentially on the size of the wing and its function and arrangement, for example on a base body.
- the section with increasing wing width and the section with decreasing wing width in the fabric flow direction or point against it are independent of the relative direction of movement between screen wall and wing with the wing according to the invention, the desired effects generate on the fabric flow.
- the wing can for example directly on the outer circumference of a base body, such as a basic rotor body, preferably essentially one cylindrical or conical rotor body, attached or be formed in one piece with the base body, or optionally attached to the base body by means of a support arm his. If the wing on the outer circumference of the main body attached and fastened there, so the attachment by welding or soldering, or it can be screwed on become. If the wing or wings directly on the Mounted on the outer circumference of the basic rotor body and fastened there there are no protruding internals, so that dead zones, Avoid spinning, braid formation or the like.
- the wing can face the generatrix of the base body be arranged inclined. This can create transition areas between individual sorting levels.
- this can opposite the tangent to the base body at an angle be employed, which is up to 10 °, or preferably up to 4 °, can be.
- an arrangement is specified according to the invention, which comprises several wings, which is characterized in that the Wing in different basic body axial planes in the circumferential direction are staggered.
- the invention relates to the design and Profiling of wings in sorting devices for fiber suspensions, especially for pulping paper, which such are optimized and chosen so that you have a streamlined Profiling the outer contour of the wing or wings without sharp Edges. This reduces the inherent resistance, and you get a significant energy saving. Further can through the section with ever increasing wing width and the section with continuously decreasing wing width, whereby both sections also merge continuously, on the one hand a suction zone in cooperation with the screen wall facing are formed, which for effective sieve cleaning provides sufficient suction, and on the other hand a Pressure zone are formed, which is a gentle material transport to the perforations of the screen wall without a sudden increase in pressure allowed. This makes the sorting quality essential improve.
- the wing 5 has an overall outer contour 6, which the Screen wall 2a facing, which has such a course, that in cooperation with the sieve wall 2a in the material flow direction (see arrow in Figures 1 and 2) a suction zone section C with increasing wing width and a pressure zone section D with decreasing wing width is formed.
- the suction zone itself is with P- and the pressure zone with P +.
- the wing 5 has one Total wing length Fl, which is equal to the sum of the length L1 of the Suction zone section C and the length L2 of the pressure zone section D is.
- the length L1 of the pressure zone section D is 0.1 to 0.45 x Fl (total wing length) and preferably to 0.3 x Fl.
- the largest wing width is designated with Fb. This will be between the side of wing 5 facing away from the screen and the highest point measured on the outer contour 6 of the wing 5.
- the leading end of the wing 5 is preferably one immediately adjacent circular section formed or runs out with a radius R3, which is in a range of 3 to 25 mm, in particular from 6 to 20 mm.
- the outer contour 6 of the wing 5 in the suction zone section C is preferably formed by a segment of a circle, which one Has radius R1.
- At the beginning of Suction zone section C, that is, at the trailing end of the Outer contour 6 may have a radius R4 which is in one Range of 1 to 5 mm, preferably in a range of 1.5 to 3 mm.
- the smallest distance between the screen wall 2a and the outer contour 6 is denoted by s.
- This distance s can be in a range from 0.5 to 10 mm, preferably from about 1.5 to about 6 mm lie.
- an angle of attack FW can be arranged, which in one area of up to 10 °, preferably up to 4 °.
- a base body for example a rotor base body (see reference number 1 in Figure 2) then employed including the angle of attack FW.
- the wing 5 which is also referred to as a hydrofoil, enables interaction with perforations 3 in the sieve 2 regardless of the profiling of the perforations on the manner described in more detail below.
- suction zone section C In the area of the suction zone P- (suction zone section C in the figures) turbulence in the area of the perforations 3 to keep clear and cleaning as well as for feeding the material through the perforations 3 generated. Due to the increasing wing width in the suction zone section C is a gentle mass transfer to the in Perforation nearest fabric flow direction 3. Starting from the Place with the largest wing width is then also a constant pressure build-up in the pressure zone section D, so that in more efficiently in the pressure zone P + the fabric through the Perforations 3 is promoted.
- the sorting quality can be improved since for example, preventing contamination by a sudden pressure increase through the perforations 3 pressed become.
- the more efficient mode of action achieved by the Profiling of the wing 5 according to the type described above and the streamlined profile of the outer contour 6, can the energy consumption of the assigned sorting device decrease. Due to the streamlined profile of the Wing 5, the inherent resistance of the same can be reduced, and there are dead zones, spinning, braids and the like avoiding either a degradation of the efficiency of the sorting device or can even lead to malfunctions and the perforations 3 can clog.
- the wing 5 allows a efficient sorting process with high quality results as well as an energy-saving, reliable operation an assigned sorting device.
- FIG. 2 shows a preferred embodiment of a sorting device shown schematically and by way of example.
