Definitions
- the invention relates to a sieving star, in particular for a screening machine, wherein the sieve star is formed substantially disc-shaped and can be arranged on a shaft, starting from the center of the sieve star at least two outwardly extending star fingers, teeth or the like are provided.
- the invention also relates to a screening machine with such a sieving.
- Such screening machines are known. They consist of a large number of rows of sieves in rows next to each other, forming a surface of sieve stars. These are spaced from each other on waves. Between the individual screen stars are gaps, so that the offset stacks of two corrugations of two waves are able to intervene in the spaces between the other screen stars.
- the stars of each row are rotatably mounted on axles or shafts. The stars are put into a rotary motion for the sieving process and, as already mentioned, interlock during the rotary movement. The distance of the stars and / or their offset determine the Siebatter grain size of the screened material.
- the material from which the stars are usually formed is plastic, hard rubber or the like. For harder to be screened materials, such. As ballast, the use of steel is possible.
- Such screening machines are very versatile. For example, for screening of gravel, shredded material, compost or cohesive soil, gravel, sand or the like such screening machines are used. If wet and heavy material is sieved, the problem arises that the screens or the spaces between the screen stars become clogged by adhering material. The cleaning of soiled sieves causes great problems in practice. The screening machine must be stopped and cleaned. Through a variety of technical innovations has been tried in the past to master this problem. For example, the stars were provided with nubs or platelets which are intended to strip off the material during the rotational movement. The mode of action of such devices is very limited and the wear is high. The resulting repairs and the associated downtime of the screen cause high costs and lost time.
- the object of the invention is therefore to provide a cleaning facility for such screening machines, which is simpler, no longer pollute so often and in particular have a high degree of self-cleaning.
- the invention is based on the prior art described above and proposes a sieving star, in particular for a screening machine, wherein the sieve star is formed substantially disc-shaped and can be arranged on a shaft, provided starting from the center of the sieve star at least two outwardly extending star fingers and the Siebstern is characterized in that the length of the star fingers is different.
- This Measure manages to achieve an excellent cleaning effect, because thereby intervene at different distances, the star fingers in the interstices and thus able to eliminate there adhering material readily.
- the machine now no longer needs to be stopped for cleaning purposes, but is also able to screen wet material sufficiently, without the need for certain cleaning cycles must be inserted. Also clamped foreign objects, such. As stones are easily eliminated by the different length of the star fingers.
- the invention simultaneously comprises several solutions. For example, it is sufficient if a single star finger of the sieve star has a different length from the other star fingers with respect to the center of the sieve star. However, it is also possible that, for example, two star fingers have the same length and all other star fingers differ from this length, that is, are shorter.
- an advantageous development of the invention is characterized in that based on the center of the sieve star and the outer circumference of the circle of the star fingers of the sieve is formed unbalanced.
- Fig. 1 of the description of the embodiments this is very clear.
- the circle of the longest sieve star is shown schematically.
- all other screen stars are made shorter, which results in an asymmetrical design of the screen star with respect to the center point.
- the invention also includes a solution according to a further aspect, according to which the outer circumference of the sieve star is provided elliptical on the circle of flight of the star fingers.
- the outer circumference of the sieve star is provided elliptical on the circle of flight of the star fingers.
- two substantially opposite star fingers are the same length and the other shorter.
- this is designed in the form of an ellipse relative to the circle of the star fingers, although also creates a certain swinging on the outer diameter of the star fingers of the screening machine in its intended use. Due to the elliptical arrangement, however, this effect is somewhat mitigated, so that an unwanted swinging up of the entire screen no longer occurs here.
- the sieve is characterized by a different length of each of the star fingers. Again, the cleaning effect that is achieved with it is excellent. The same occurs in the next embodiment of the solution according to the invention, according to which two opposite star fingers have the same length. This embodiment also clearly serves to improve the cleaning effect, which is caused by the sieve movement itself, namely the rotational movement of the stars. It does not matter whether the two opposite waves perform a same direction of rotation or an opposite direction.
- the invention also includes a sieve star, as previously described, characterized by an even number of star fingers.
- a sieve star as previously described, characterized by an even number of star fingers.
- it is certainly intended to provide six star fingers or twelve star fingers for the sieve star.
- the invention also includes a solution characterized by an odd number of star fingers.
- the star fingers are provided as rod-shaped or triangular or trapezoidal tips, teeth, noses, hooks or the like.
- the invention is not limited to a specific form here. However, an approximately star-shaped configuration or shape has prevailed seen laterally, in which the star fingers are slightly semicircular rounded and preferably, as will be described later, are flattened at their top.
- the invention is not restricted to even or even an odd number of star fingers. Accordingly, it is also included according to the invention to equip the sievers with seven star fingers, nine star fingers or twelve star fingers.
- a preferred embodiment of the invention is characterized in that the star fingers have flattening or flattening at their outer ends. These flattening or flattening serve to avoid jamming, for example by trapping foreign bodies. Also, the wear is minimized by a flattened configuration of the star finger at the outer end.
- At least one of the star fingers has an attachment at its tip or at the flattening.
- This approach is designed for example as nose, as a tip, as a pin, as an increase or the like.
- this approach preferably does not fill the entire area of the flattening but only a portion, so this approach actually serves to further enhance the cleaning effect.
- a further variant of the invention provides that two lugs are arranged on approximately opposite, preferably the longest, star fingers. This is quite sufficient, since the approaches to relatively shorter star fingers remain relatively ineffective. However, this does not exclude that they are also provided there to loosen possibly fixed material, which can then be transported by the longest star finger with his approach from the space between two screen stars out.
- the invention encompasses both an embodiment in which the sieve star is shaped, as it were, from a piece of material, as well as an embodiment in which the star fingers extend outward from a flange provided in the interior of the sieve star.
- the sieve star with the flange and the star fingers can also be provided in one piece. It is also possible to form the star fingers on the flange or fasten.
- the invention further proposes that an opening is provided in the previously described flange, which serves for fastening the screen star on a shaft or the like.
- This opening is adapted to the shape of the shaft and can thus be round, oval, triangular, square, rectangular, hexagonal or polygonal.
- the opening in the flange of the screen star is made according to and corresponding thereto.
- the opening for receiving a formed as a form of shaft shaft is formed in a corresponding manner to positively and / or positively receive the particular formed as a hollow shaft form shaft.
- Such shaped waves as hollow shafts in particular designed in the manner of a hexagon, are known for special purposes and therefore also serve in an excellent manner to receive screen stars according to the invention.
- the opening is arranged offset or rotated with respect to one of the star fingers, for example the longest star finger, in particular in order to enable an offset of the star fingers by an angle of 15 ° to 90 °, preferably by 30 °.
- This makes it possible, for example, the star fingers relative to the longest star finger, to arrange in a kind of spiral on the shaft.
- This has the further advantage that the cleaning effect is further improved and in particular is caused by the fact that a swinging of the entire screening device is completely avoided by this design of the screen stars on the shaft, because this is a certain mass balance.
- the screen star or the star fingers are at least partially formed of a rubber-like or elastic material. It has proven to be advantageous to select the material that it to the conditions of each product to be screened is adjusted. For example, it has proven to be extremely effective on compost soil to use a softer rubber material than was previously the case. However, this does not exclude that even harder material, for example, in the screening of gravel is used.
- the previously described embodiments of the solution according to the invention of the sieve star can also be used for all other materials which are suitable for the manufacture of a sieve star.
- a further advantageous embodiment of the invention is characterized in that the sieve star in its center at least one reinforcement of a stable material, such. As metal, fiber reinforced plastic or similar solid material. On this stable material, for example on the flange, then the star fingers are attached. This has the advantage that the wear which could occur due to the transmission of force, for example on the shaft, if a material which is not strong enough there would be used, is avoided.
- a stable material such as metal, fiber reinforced plastic or similar solid material.
- a variant of the invention is also distinguished by the fact that the flange of the screen star described above is formed of metal and the star fingers on this flange on or vulcanize and / or sprayed, sprayed on and / or up or are cast. This ensures that a stable connection between the flange and the shaft is formed, which is able to transmit sufficient forces to ensure a very fast screening process.
- the star fingers are made of softer material, such as rubber, which positively affects the screening effect for certain products in any case.
- At least one, preferably oblong hole-shaped cleaning bore is provided in the flange. This makes it possible that certain material particles that can not escape from the space between the individual screen stars can then be removed through this cleaning hole. Furthermore, caused by the offset of the individual screen stars on the shaft and the cleaning holes an additional cleaning effect, so that it is possible by this measure, almost completely avoid blockages.
- Another aspect of the solution according to the invention is characterized in that at least on one of the thickness-forming sides of the flattenings a bevel is provided which breaks the edge of the flattening to the thickness of the star finger forming side.
- This measure also serves, on the one hand, to reduce wear and, on the other hand, also to further improve the cleaning effect, since it is possible by means of this chamfer to further improve the cleaning effect.
- the thickness or thickness of the flange corresponds approximately to the thickness of the star-shaped finger. If necessary, it is sufficient to provide a clearance, which allows the passage of the star fingers past the flange, which is in the range of 1/10 mm to a maximum of 1 mm.
- the invention also relates to a screening machine, in particular star screen, consisting of a plurality of arranged in rows next to one another in a plane, rotatably mounted on shafts, axles or the like, intra-gripping screen stars with a sieving, as previously described.
- a screening machine in particular star screen, consisting of a plurality of arranged in rows next to one another in a plane, rotatably mounted on shafts, axles or the like, intra-gripping screen stars with a sieving, as previously described.
- the stars intermesh with each other in such a way that the star tips engage the screening stars arranged on a first shaft in the spaces between the screening stars of a second shaft. This greatly increases the cleaning effect and in particular the screening effect.
- the distance of the waves to each other or the distance between the star tips of the flanges of the screen stars determines the particle size of the screened material.
- the waves on which the screen stars are arranged are designed to be displaceable relative to each other, so that one can choose
- the waves are formed as shaped waves, which in particular have six trapezoidal segments on their outer sides, between which extend semicircular or semi-circular recesses.
- shape waves which are designed in particular as a hollow body, are characterized by a low weight and are also extremely stable and provide a very favorable power transmission from the shaft to the screeners. It is also advantageous if the corrugation formed as waves on its inner side also have trapezoidal shaft sections.
- the screening machine is characterized in that the screening stars provided on a shaft are arranged rotated against one another on the shaft, so that due to the offset, a spiral-shaped screening wave is produced. Two such arranged waves are then advantageously employed against each other so that the longest screen stars or star fingers are still able to pass just past the flange of the screen star with sufficient distance from each other.
- a development of the invention is characterized in that at least two shafts are spaced from each other such that each of the longest star finger of the flange or approach at a small distance between 0.5 mm to 3.0 mm during the rotational movement, especially during a Turn can pass by.
- the invention is also characterized in that the at least two waves can be driven at different speeds. For this purpose, it may be necessary to provide appropriate gear and / or drives on the screening machine. It does not matter whether the individual shafts are driven by a prime mover and the individual shafts are subdivided differently by means of one or more transmissions, or whether each individual shaft is provided with a single drive which effects the rotational movement, it is possible according to the invention to use different ones To transmit speeds to the individual waves that carry the screen stars.
- FIG. 7 shows a hollow shaft for a screening machine according to the invention in side view
- FIG. 8 three-dimensional representation of a
- Fig. 1 shows a first embodiment of a screen star I according to the invention.
- the star fingers are denoted by the reference numerals 1 to 9 in this embodiment.
- the star fingers have 1 to 9 different lengths. This is indicated by the reference symbols I 1 , I 5 and I 7 and the corresponding double arrows.
- the length is measured starting from a center Z of the sieve star.
- an opening 13 is provided, which is formed in this embodiment substantially square.
- the square configuration is intended to equip, for example, a square shaft with a plurality of screen stars I, which are then arranged side by side in the longitudinal extension of the shaft.
- this flange 16 has a certain thickness, in particular such a thickness, which corresponds to the thickness of the star fingers 1 to 9, so that mutually interlocking arrangement of sieve fingers 1 to 9 is achieved.
- the sieve star carries schematically only the reference I, which is indicated by an arrow on the right next to the illustration in Fig. 1.
- the reference character K designates the outer circumference of the longest star finger 1. It is clearly evident from the circle circumference K, which has been selected only for illustration, that the individual star fingers 1 to 9 have a different length.
- the individual star fingers 1 to 9 also have a flattening 15 which is preferably rounded or chamfered at their corners. This flattening serves, as already described above, to reduce wear and in particular to improve the cleaning effect. In Fig. 1, therefore, the unbalanced configuration of the star fingers 1 to 9, based on the circumference of the circle, shown.
- FIG. 2 shows a second embodiment of the screen star invention I.
- the other starfingers on the other hand, are shortened again so that, seen in the outer perimeter, no circle arises, as can be seen, but an ellipse. It is therefore the elliptical design of the sieve star according to the invention. All other reference numerals will be reused in the same way.
- a projection 14 on the star finger 1 and a projection 17 on the star finger 7 are provided in FIG.
- the flange 16 has in this embodiment, cleaning holes 18 which are formed slot-like. These cleaning holes 18 allow an improvement in the cleaning effect, because it succeeds to dissipate any adhering material through these holes still. These can only be extremely small particles that normally otherwise accumulate The flange or in the spaces between the star fingers could lead to a blockage of the screen. In the prior art, this was often the case, which is substantially avoided by the configuration, as it is now chosen according to the invention.
- the opening 13 is selected circular in the embodiment of FIG. 2, so that this sieve star can be placed on a round shaft. This can be done, for example, in the form of tongue and groove joints or by shrinking in order to achieve optimum power transmission from the shaft, not shown, to the screeners.
- Fig. 3 also shows an elliptical configuration analogous to Fig. 2, but this variant differs by a turn square opening 13. All other reference numerals are reused in the same way.
- FIG. 4 shows a three-dimensional representation of the sieve star, as has already been presented in the preceding FIGS. 2 and 3.
- the screen star I has on both sides a flange 16, which essentially corresponds to the thickness or thickness of the star fingers 1 to 12.
- the opening 13 is in turn here square provided with slight rounding or flattening at the corners.
- the representation is likewise the elliptical configuration, which, however, in comparison with FIG. 5, which is shown below, makes visible that it is possible to arrange the opening 13 offset or twisted with respect to the first star finger 1.
- helical arrangement of the screen stars I is made possible on the shaft not shown here.
- the chamfer 15/1 on the sides of the flattening 15 can be seen, which ultimately break the edge to the thickness or depth of the star fingers and thus provide a reduction in wear and / or an improvement in the screening effect.
- a further embodiment is shown, which ultimately differs only by the design of the flange of the previously described variants.
- the flange 16 is circular in this embodiment, wherein the opening 13 is formed for receiving a mold shaft, not shown. It is indicated that in the flange corresponding to trapezoidal Wellenab- cut the shaft, not shown, also trapezoidal shaped elevations 20/1 are provided.
- Fig. 7 shows the side view of such a shaped shaft, which is designed as a hollow body and in particular on its outer side has six trapezoidal segments 22. These trapezoidal segments 22 are located between semicircular or semi-circular recesses 23 on the outside. On the inside of the already mentioned trapezoidal wave sections 20 are provided, which extend between recesses 24, which are also formed substantially trapezoidal.
- FIG. 8 shows a three-dimensional representation of the variant of the star-shaped finger according to the invention already shown in FIG. 6 from a different perspective.
- FIG. 9 schematically shows the design of a screening machine, in particular star screening machine with a screen star I according to the invention. Shown only schematically are two waves 21/1 and 21/2, the screen stars I wear. Due to the staggered arrangement of the screen stars I on the waves 21/1 and 21/2 results in a spiral arrangement, which is clear by the name of the longest star fingers 1. These are essentially offset in each case by a certain angle on the shaft, which is why the already mentioned several times, advantageous embodiment of the arrangement of the screen stars I results according to the invention.
- the waves 21/1 and 21/2 can be stored so that they are variable in their distance from each other according to the respective goods to be screened.
- the screening machine has corresponding drive units and / or transmission elements, such as gear or the like.
- a star screen according to the invention has a plurality of the illustrated waves in an opening forming the screen surface.
