Definitions

  • the invention relates to a blade separator for the comminution and separation of breakable material, in particular for soil and soil preparation, compost preparation and use for a wide variety of materials in the recycling sector for the extraction of secondary raw materials.
  • Blade separators are known. They are used as accessories and special equipment for wheel loaders and excavators for sieving, loading, refilling and also for soil improvement.
  • DE 93 04 186 U describes a shovel separator called a sieve crusher for earth material, which has a housing designed as a bucket, the rear wall of which is designed as a crusher sieve and in which parallel and in the operating position, essentially horizontally arranged rotating hollow shafts with an axial axis Are spaced from each other on these rotationally fixed separation disks and crusher elements. Adjacent hollow shafts are arranged in such a way that the separation disks are arranged opposite one another in one plane.
  • a breaker element which has teeth, is rotatably held in the space between two adjacent separation disks of a shaft.
  • the distance between the shaft shells and the distance between the separation disks arranged adjacent to a shaft determines the sieve fineness of the crusher sieve.
  • the hollow shafts are synchronously rotated via a chain drive on the outside of the housing.
  • the separation disks are welded onto the hollow shafts in this blade separator. This requires a thick-walled tube to keep the stresses generated by welding and the weld seams low.
  • the crusher duck brackets are also welded on. The stresses caused by welding due to the operational alternating voltages in the shafts (tensile / compressive stress) micro cracks and consequent stress corrosion cracking and increased wear. Depending on this, the separation disks and the crusher elements or the shafts must be regenerated or replaced. This process is complex and must expediently be carried out in a workshop, the regeneration in turn being associated with a welding process.
  • the rotating hollow shafts which are arranged in parallel in a separator housing in a known manner, with separating disks arranged axially at a distance from one another on these and with crusher elements arranged in a rotationally fixed manner, are each held according to the invention between two clamping plates arranged on the end faces thereof and by an axially extending and clamping rod in operative connection with the clamping plates is subjected to considerable pressure.
  • the hollow shaft is under considerable compressive stress, and alternating stresses during operation of the blade separator, microcracks and stress corrosion cracking are avoided, which considerably reduces wear and increases the service life.
  • the thickness of the tube wall can be reduced considerably.
  • the voltage dividers are advantageously provided with a central recess for carrying the tension rod, the profile of which is adapted to that of the tension rod.
  • the ends of the tension rod can be provided with a thread for a tension nut forming the tensioning means.
  • the hollow shaft is pressurized in particular in its axial direction, it is possible to distance itself from the welded construction and its disadvantages and to form the hollow shafts from individual shaft sections between which the separating disks are held in a rotationally fixed manner by a press fit.
  • This "modular design" has the advantage of minimizing assembly and regeneration effort.
  • the basic elements clamping plate, clamping rod and in particular the shaft sections are not subject to any significant wear and are therefore reusable.
  • the dimensions of the hollow shafts and the separating disks arranged between their shaft sections can be varied in a simple manner and can be easily adapted to the material to be broken and also to customer requirements.
  • the shaft sections for centering on the tension rod can be provided with a centrally arranged centering disc with a central recess adapted to the profile of the tension rod. In this way, an adjusted press fit of a separation disk between two shaft sections can be ensured and a contribution to the torsional strength can be made.
  • the crusher elements can either be arranged on the shaft sections or on the separation disks, preferably releasably on a respectively fixed holder, so that they can be replaced quickly and easily, in particular on the construction site. 4
  • breaker elements are arranged on the shaft sections, adjacent hollow shafts are arranged in such a way that their separation disks are arranged opposite one another in one plane.
  • separation disks of adjacent hollow shafts can be arranged offset with respect to one another and arranged to engage in the space of the other hollow shaft formed between two adjacent separation disks. This results in an increased sieve fineness and the particle size of the shredded and sieved material is considerably reduced.
  • the separation disks can also be designed as breaker elements themselves for certain purposes, in particular for processing less solid material or for the separation of bulk goods, for example with strips or metal objects, in which the breaker elements usually designed as flails could get caught.
  • they are polygonal and at least in the corners are provided with a wear-resistant layer.
  • the arrangement of adjacent hollow shafts can be carried out in such a way that their separation disks are arranged opposite one another in one plane, or - to produce smaller particles in the separated and sieved material - offset from one another and in each case in the space formed between two adjacent separation disks interfering with the other wave.

  • the cohesion of the hollow shafts 1 is only given when they are pressed between two clamping plates 4 arranged at the end, which are connected by a clamping rod 5 (FIGS. 2, 3) that connects them and is guided in the shaft sections 1 a and the separation disks 2 (FIG. 2, 3) ).

Abstract

L'invention concerne un séparateur-tracteur utilisé pour réduire en morceaux et diviser un matériau apte au concassage, qui comporte un carter de séparateur dans lequel sont disposés, parallèlement et en position de travail, sensiblement à l'horizontal, des arbres creux rotatifs sur lesquels sont montés, solidaires en rotation et séparés les uns des autres par des intervalles axiaux, des disques de séparation ainsi que des éléments de concassage, également solidaires en rotation. Cette invention permet d'augmenter la durabilité du séparateur-tracteur. A cet effet, les arbres creux (1, 15) sont maintenus chacun entre deux plateaux de serrage (4) disposés sur leurs faces, lesquels sont tirés l'un vers l'autre par une tige de serrage (5) disposée axialement dans l'arbre creux (1, 15), ce qui crée une sollicitation importante en pression de l'arbre creux (1, 15). Lesdits arbres creux (1, 15) peuvent être constitués de segments d'arbre (1a) individuels, entre lesquels les disques de séparation (2; 16; 19; 20) sont fixés par ajustage serré.
