Definitions

  • the invention relates to a rotary screen element as well a method for cleaning rotary screen elements.
  • G 93 07 096.9 are screening systems known which for pre-sorting bulk goods, such as compost, bark humus or mulch, peat and so on, but also in building rubble recycling application Find.
  • These screening systems belonging to the state of the art are constructed in such a way that parallel synchronous drives Shafts rotatably and axially offset from each other to gap Groups of sieve stars made of molded rubber parts with have resilient fingers.
  • the fingers are lagging in the circumferential direction and as a sickle-shaped Scraper tines formed.
  • the respective distances between adjacent screen stars and screen star rollers adapted to the goods to be sorted.
  • Adhesive material must be elaborate and restrict production Devices are removed. This Devices are complex, expensive and not in the long term can be used for effective and effective cleaning. In addition, these must be part of the state of the art Devices of the screening process for the cleaning process be interrupted, which is also a disadvantage.
  • the technical problem underlying the invention consists of a rotary screen element and a method for cleaning rotary screen elements and their gaps specify with which a continuous cleaning is possible, the cleaning process during the screening process takes place and which is also easy and is inexpensive.
  • the reinforcing part according to the invention has a larger one radial expansion as axial expansion. It is advantageously essentially the crescent shape of the at least trained a finger.
  • the reinforcement part Because of the radial expansion of the reinforcing part at least as large as the radial extent of the Fingers is, that is, the reinforcement part either almost flush with the finger or over the If the finger protrudes, the reinforcement member moves with every revolution over the collar of the adjacent rotary screen element.
  • the reinforcing part has a larger one Stiffness as the finger of the rotary screen element on.
  • the rotary screen elements usually consist of Rubber or an elastic plastic.
  • the reinforcing part made of steel is particularly advantageous wear-free steel, plastic and / or one made of ceramic material.
  • the reinforcing part is advantageous on the side of the Fingers arranged, which is in the forward direction.
  • the finger points to the attachment of the reinforcement part at least one hole.
  • the reinforcing part points also at least one hole, the holes are arranged in such a way that the bores lie one above the other, when the reinforcement part is fully assembled.
  • a fastening element is inserted and fastened. Becomes If a rivet is used, it is expanded accordingly. It it is also possible to use bolts or the like.
  • the hole is advantageous to increase stability in the outer half or in the outer third of the Fingers arranged.
  • the reinforcing part has at the end which in Direction of the hub of the rotary screen element arranged is, at least one protrusion in a recess a throat adjacent to the finger is arranged.
  • the finger Since the reinforcement part is advantageously on the side of the Finger is arranged, which is in the forward direction of the finger lies, the finger with the arranged on it If necessary, avoid the reinforcement part during the sieving process should be necessary.
  • the finger is still compliant designed, but has a much higher Stiffness than the rest of the fingers.
  • the throat that the finger with the reinforcement part in Trailing direction is arranged adjacent, in a larger Degrees closed than the remaining throats so the Finger becomes even more stable overall.
  • the reinforcement part arranged in a finger.
  • the reinforcement part is at least partially from the material of the finger.
  • the reinforcement part is not after attached to the manufacture of the rotary screen element, but during the manufacturing process of the rotary screen element immediately incorporated into this.
  • the reinforcement has openings. In this case will have a better connection with the elastic Rotating sieve element achieved.
  • the reinforcing part is in a finger of the rotary screen element arranged, the reinforcing part is advantageous with a hook-shaped or eyelet-shaped Provide end, which in the hub area of the rotary screen element is arranged.
  • each rotary screen element a reinforcement part of a screening system to provide.
  • the device according to the invention has the advantage that continuous cleaning is possible.
  • the actual The screening process does not have to be interrupted for cleaning.
  • Fig. 1 shows a rotary screen element (1) with fingers (2, 3, 4), which are arranged on a hub (5).
  • the Hub (5) has a square recess (6) for the Recording a wave (not shown).
  • a reinforcing part (7) is arranged on the finger (3), one with a rivet (8) on the finger (3) is attached.
  • a projection (9) of the Reinforcing part (7) in a recess (10) of the rotary screen element, so two attachment points of the Reinforcement part (7) on the rotary screen element (1) are.
  • the recess (10) is in a throat (11), which is arranged adjacent to the finger (3).
  • the rotary screen element (1) is in the direction of Arrow (A) rotated so that the reinforcing part (7) is in the forward direction of the finger (3).
  • the throat (12), which is in the wake direction to the Finger (3) is less deep than the rest Fillets (13, 14) of the rotary screen element (1). This increases the stiffness of the finger (3).
  • Fig. 2 shows the reinforcing part (7), which one Bore (15) and the projection (9).
  • a radial one Extension (c) of the reinforcing part (7) is greater than an axial extent (d).
  • the reinforcing part (7) is angled formed so that the reinforcing part (7) essentially has the shape of the sickle-shaped finger (3).
  • Fig. 5 shows the rotary screen element (1) and others Rotary sieve elements (19, 20).
  • the rotary screen elements (1, 19, 20) are arranged relative to one another in such a way that the fingers (3, 21, 22) interlocking are.
  • the reinforcing elements (7, 23) bearing fingers (3, 24) have such a radial extent on that they attached to a fret (25, 26, 27) of the neighboring Impact rotary screen elements (1, 19, 20) or almost bump to any adhering dirt or the like to solve.
  • the axial extent (e) of the finger (3) is slight greater than the axial extent of the reinforcing part (7).
  • the radial extension (f) of the finger (3) is smaller than the radial extension of the reinforcing part (7).
  • Fig. 8 shows a rotary screen element (36) with a Reinforcing element (37), which is arranged in a finger (45) is.
  • the reinforcing part (37) has an eyelet shape formed end (38).
  • the sieve (39) has shafts (40), on which in turn elastic trained rotary screen elements (41) are arranged.
  • the rotary screen elements (41) are from shaft to shaft (40) offset and interlock.
  • the sieve elements are by means of a drive (42) engaging the shafts (40) 43) driven in the same direction.
  • the passage width of the sieve (39) is determined by the distance between them gripping elastic rotary screen elements (41) certainly.
  • the rotary screen elements (41) have reinforcing parts (44) with which the sieve moves during the Screening process cleans itself, since material adheres on the elastic screen elements (41) during operation is continuously prevented.
