Definitions

  • the invention relates to a disc for a disc screen or a disc separator, which several in parallel in a frame arranged, rotatably drivable shafts on which several such disks on gap and interlocking are arranged, with a disc body, the one as Polygon with an even number of corners designed circumference, two side faces and one of the number of corners of the polygon has a corresponding number of partial areas on the circumference and consists of an iron material, being in the direction of the circumference of the window body every second corner with a scraper is provided, at least on one side over one of the side surfaces protrudes from the disc body.
  • Such disc sieves or disc separators are particularly suitable for separating difficult to screen Masses. They are high compared to other seven Capacity in relation to their size.
  • DE 44 30 682 A1 shows a disc sieve with decagonal discs an improved disintegration of the screenings takes place. On cohesive screenings have a tendency to stick to the discs or to fix and build on the shaft hubs. To do this prevent wipers are provided.
  • the polygonal version The washer is required to put the good on the washer continue to transport towards the next slices. The window corners also ensure that a cheap Unlocking takes place. Due to the rapidly rotating decagonal Discs, the mass to be treated is swirled, causing there is a large increase in volume.
  • Soils become a favorable prerequisite for inclusion of means achieved, for example, the length of stay of To significantly reduce land on rents for treatment.
  • disc sieves or separators be used to develop a certain grain size.
  • the swirling also ensures that a good mixing effect is achieved.
  • the disadvantage is that the corners are wear quickly, depending on the material to be processed is. This means high maintenance costs and downtimes or a deterioration in functionality.
  • the invention is therefore based on the object of a disc to propose for a disk sieve or a disk separator, which is suitable even for a long service life to ensure the desired mode of operation, i.e. where the Original geometry is retained over a long period of time.
  • the wipers at least partially consist of a hard metal and that the disc body in the area of not using scrapers provided corners has recesses in which plate elements are made of hard metal, which enclose the corners and each starting from a corner over a partial length the subsequent one and towards those occupied with wipers Extend corner partial areas.
  • a favorite Tungsten carbide comes with 80 to 90% tungsten carbite and with cobalt or nickel binder in question.
  • a disc sieve or a disc separator and an embodiment a disc are schematic in the drawing shown and explained in more detail using the same.
  • the disc sieve or the disc separator according to FIG. 1 and 2 comprises a frame 1, in which waves at a parallel distance 2 are rotatably arranged.
  • the waves 2 each carry Disks 3 standing on gap held by spacer sleeves are.
  • the discs 3 are non-rotatable with the associated Waves 2 connected.
  • the discs of two neighboring ones Waves interlock in the gaps between two one Shaft assigned discs 3.
  • the discs 3 are polygonal are.
  • the disks 3 each have several Corners scraper 5 on at least one of their side surfaces protrude. These are used on the side surfaces to strip off the adhering discs 3 adhering material.
  • the shafts 2 are driven in rotation by a drive 4. Chain or belt drives, for example, through the forced synchronization of the rotation the waves 2 are generated with each other, so that the Side surfaces protruding stripper 5 are not mutually can touch.
  • the disks 3 turn in one direction driven so that the goods from one task end, for example located in the area on the right of frame 1 Wave in the direction of the last one arranged on the left of the frame Wave due to the polygonal design of the discs transported and opened up and screened in this way is so that it is through the gaps between the interlocking Slices 3 can fall.
  • FIG. 3 shows a disk 3 'for use in a disk separator or a disc sieve according to FIGS. 1 and 2, the disc body 6 is formed on the circumference of a decagon is, ie has ten corners 8, between each of which partial areas 9 are arranged. One of the side faces is recognizable and designated 10. In the center of the disc body 6 an opening 7 is arranged, with which the disc 3 'rotatably on one of the shafts of the disc sieve or disc separator can be set.
  • Corners 8 It is an even number of Corners 8 provided. An even number is correspondingly of ten partial areas 9 available. Seen over the scope, is every second corner 8 is provided with a scraper 5, which at least from the partial area 10, i.e. protrudes from the drawing level. Such wipers 5 can, for example, at least themselves partially consist of a hard metal. In the field of corners 8 not occupied by scrapers 5 are in the pane body 6 recesses exist in which plate elements 11 from Tungsten carbide are used, which include the corners 8 and themselves each starting from a corner 8 over a partial length of the subsequent and in the direction of the wipers 5 Corners 8 extending partial areas 9 extend.
  • the plate elements 11 have essentially the thickness of the disc body 6 and are with this by a solder or the like Means indissolubly linked. It’s enough for some use cases if of the two partial areas each belonging to a corner 8 9 only one is provided with a plate element 11, which includes corner 8.
