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 disk body, the one as a polygon designed perimeter, two side faces and one of the number of Corners of the polygon corresponding number of partial areas on the circumference has and consists of an iron material.
  • Such disc sieves or disc separators are particularly suitable for separating masses that are difficult to screen. They have a high capacity compared to other seven in relation to their size. Polygonal are preferred Disks, e.g. with six, eight or ten corners, chosen by an improved disintegration of the screenings takes place. A Cohesive screenings have a tendency to stick to the discs or on to fix and build up the shaft hubs. To prevent this, wipers are provided. The polygonal version The slices are required to continue the good on the slices in the direction of the next slices. The Disc corners also ensure that a favorable unlocking he follows.
  • the invention is therefore based on the object of a disc propose a disc sieve or a disc separator, which is suitable, the desired one even for a long service life To ensure the way of working, i.e. where the original geometry over a long period of time.
  • At least one of the sub-areas of the disk body with armor is made of hard metal, which has an associated corner comprises and extends over at least part of the length of the partial area extends.
  • the armor is formed provided in the form of plate elements made of hard metal exist and are attached to the disc body.
  • the armor is connected to the partial area by a solder.
  • the armor preferably closes from a corner also the partial areas emanating from this at least over one Partial length of the same. However, it is also possible to use the partial areas along their entire length with armor Mistake.
  • the disc body has an even number of corners, that in the direction of the circumference of the disc body each second corner is provided with a scraper that at least protrudes unilaterally over one of the side surfaces of the disk body and that the sub-areas arranged between them too the armor towards the corners not provided with wipers exhibit.
  • hard metal chippings it is preferred those with a grain size of 0.6 to 1.8 mm selected.
  • a material for the disc body comes from steel the quality 42CrMo4 or 50CrVMo4 in question.
  • a disk sieve or a disk separator and two embodiments a disk are shown schematically in the drawing and explained in more detail using the same.
  • the disc screen or the disc separator according to Figures 1 and 2 comprises a frame 1, in which waves 2 at a parallel distance are rotatably arranged.
  • the shafts 2 each carry disks 3, which are held in a gap by spacer sleeves.
  • the Disks 3 are rotatably connected to the associated shafts 2.
  • the disks of two adjacent shafts engage each other in the gaps between two assigned to a wave Discs 3 a.
  • the discs 3 are polygonal are.
  • the disks 3 each have several Corners wipers 5 on at least one of their side surfaces protrude. These are used on the side surfaces of the to strip opposite discs 3 adhering material.
  • the Shafts 2 are driven in rotation by a drive 4.
  • a drive 4 For this serve for example chain or belt drives through which forced synchronization of the rotation of the shafts 2 with each other is generated so that the protruding from the side surfaces Wipers 5 can not touch each other.
  • the disks 3 are driven to rotate in one direction, so that the goods from one task end, for example in the area of arranged on the right of frame 1 in the direction of the left on Last shaft arranged due to the polygonal frame Execution of the discs transported and unlocked in this way and is sifted so that it passes through the gaps between the interlocking discs 3 can fall.
  • the disks 3 are in the area the corners and their adjacent surfaces at least partially provided with armor, which is shown in FIGS and 2 is not apparent, based on Figures 3 and 4 for two However, embodiments are explained in more detail.
  • FIG. 3 shows a disk 3 'for use in a disk separator or a disc sieve according to Figures 1 and 2, the Washer body 6 is formed on the circumference, ie has ten corners 8, between which partial areas 9 are arranged are. One of the side faces is recognizable and with 10 designated. There is an opening in the center of the disk body 6 7 arranged with which the disc 3 'rotatably on one of the shafts of the disc sieve or disc separator can. An even number of corners 8 is provided. Corresponding is also an even number of ten faces 9 available. Seen over the circumference, every second corner is 8 a scraper 5 provided, at least from the partial area 10, i.e. protrudes from the drawing level.
  • Such wipers 5 can, for example, themselves at least partially from a hard metal consist.
  • Corners 8 are 6 recesses in the disc body, in which plate elements 11 made of hard metal are used, the embrace the corners 8 and each start from a corner 8 over a partial length of the subsequent and towards the partial stripes 9 with scraper 5 occupied corners 8 extend.
  • the plate elements 11 have essentially Thickness of the disk body 6 and are with this by a solder or similar means inextricably linked. It is enough for some Use cases if of the 8 belonging to a corner two partial surfaces 9 are only provided with a plate element 11 which includes corner 8.
  • the disc 3 'to be formed without a scraper 5 possible, all corners 8 with armor in the form of the plate elements 11 to be provided.
  • the plate elements 11 there is also the possibility to guide the plate elements 11 so far that they are extend over the entire partial areas 9 or in the event that wipers 5 are present, reach up to these.
  • FIG. 4 shows an alternative embodiment to that according to FIG 3.
  • the disc 3 '' is also designed as a decagon, i.e. it has ten corners 8, each connected by partial surfaces 9 are.
  • the between two scrapers 5 on the circumference lying free corners 8 are with armor in the form of Carbide chips 12 provided.
  • the partial areas 9 are outgoing each from a corner 8, which is included in the armor, i.e. is also equipped with hard metal chips 12, at least over a partial length of the partial areas 9 in the direction of the corner 8, which is equipped with a scraper 5, with hard metal chips Mistake.
  • the hard metal chips 12 preferably have a grain size from 0.6 to 1.8 mm and is with the partial surfaces 9, i.e.
  • a stocking, i.e. Armor, the other corners 8 in the area of Scraper 5 is not required if, for example at least partially also consist of a hard metal and thereby the wear of the disk body 6 'also in this area is effectively reduced.
