Definitions

  • the present invention relates to a slag crusher. These are devices for the mechanical processing of slags by means of impact elements.
  • Slags in the context of the present invention are conglomerates of materials of different densities and possibly also of different consistency. Slags are known to be involved in ore processing or as a combustion residue. In particular, in the waste recycling in the context of waste incineration fall to slags. However, slags in the context of the present invention are also landfill masses of different types and other conglomerates of the type mentioned. Such slags generally consist, for example, of soils, sands, stones and inclusions of the most varied types, ie ferrous metals, non-ferrous metals, light metals, precious metals and the like. It is known that slags are mechanically broken or digested in that they are simply crushed with hammer mills or impact mills.
  • an apparatus for the mechanical processing of slags by means of impact elements with a processing chamber formed in a housing having a filling opening and an outlet opening. At least one rotor is arranged in the processing chamber. Depending on the design, at least two rotors rotating about an axis are arranged with striking elements. One of the two is with respect to the slag flow a leading rotor, the other, seen in the direction of slag flow behind it as a subsequent rotor. The rotors are passed by the slag stream on the way from the fill port to the outlet port. Usually the slags move gravitationally. That is, the intended processing position of respective devices is such that in a vertically upper position viewed a filling opening.
  • the drive axle is usually vertical, so that the rotor planes extend horizontally, that is perpendicular to it.
  • the slags filled in above thus fall down through the processing chamber and pass through the different rotor levels. They are processed accordingly, that is at least partially contacted by the impact elements of the rotors. After the last rotor, the slags fall into the area of the outlet below.
  • the previously known device with successive bulging rotor bores has the disadvantage that the processing densities of the slag streams are undefined or uncontrolled.
  • machining density is understood to mean the amount of slag flow supplied to a rotor being processed by means of the impact elements guided by this rotor. Whether a slag stream is fed via a feed opening, a feed channel or from a leading rotor, a slag stream reaches the rotor plane and must pass through it. That's it Obvious that, depending on circumstances and construction, not all parts of the slag flow passing through the rotor plane are also hit by the impact elements of the rotor and thus processed.
  • the present invention has for its object to provide a device for the mechanical processing of waste by means of beating elements having an improved efficiency.
  • a rotor is designed such that it has a machining density of at least 90% of the slags of the slag stream fed in. According to the invention, therefore, about 90% of the conglomerate constituents which make up the slag flow are struck by the impact elements of the rotor and thereby processed, ie broken up.
  • the purpose of the processing device is to introduce slags of a certain grain size into the filling opening. Slag with a correspondingly smaller grain size, or conglomerates of materials corresponding to broken size, is then obtained at the outlet opening.
  • a slag stream is introduced at a filling opening in a corresponding processing chamber, this first passes through the first rotor plane and is partially broken up.
  • the slag stream was preferably pre-screened and covers a previously known size range. Since the drop height to the rotor plane is known as well as the falling speed, a certain processing density of the slag flow can be estimated. With the invention it was found that, depending on the size of the impact element, the number of impact element and the rotational speed taking into account the other previously known parameters such as feed rate (V z ), grain size, drop height and slag volume and the like, the machining density can be estimated or influenced. According to the invention, the entry speed (V E ) can thus be controlled.
  • a rotor for machining a given grain which is guided over a known height in the rotor plane, formed with a corresponding number of striking elements.
  • the impact element can be designed according to the invention in the length and width, with respect to the rotor plane. But they can also be dimensioned in terms of their height, that is, essentially in the direction of slag flow. Since the impact elements rotate about the axis, an optimal processing takes place when a striking element strikes slag with its side wall defined by the height. Knowing the slag flow and the number of rotating impact element and their height, a hit probability can be given, which can be used as a measure of the machining density.
  • the device itself is to be designed so that it allows a rotor speed corresponding to the machining density.
  • individual rotors or rotor groups can be arranged on a drive axle.
  • the impact element impactors which are fastened by means of chain links to the rotor axis. According to the invention, they have beveled side edges. In this way, the slags hit still receive a directional impulse and can be conveyed, for example, again in the area above the rotor plane, which also increases the processing density.
  • successive rotor groups can have mutually independent drive axes and thus be operated differently.
  • the device according to the invention is a realization of the method according to the invention, which allows correspondingly high processing densities by the design of the rotor plane.
  • the housing 2 has filling openings 3, 4, 5. These can be closed by covers, not shown. In the lower area an outlet opening 6 is formed.
  • a conveying device for slags is shown in the region of the inlet opening 4, with which the slag flow can be dimensioned or controlled.
  • drive axles 8, 9 are shown, to which rotor elements 10 are fastened. These are shown in the embodiment shown as a paddle, but can also be attached to chains impactors and the like.
  • a slag crusher 1 functions in such a way that slags are introduced into one or more filling openings 3, 4, 5. These then pass through the different rotor levels and are processed by the rotors accordingly, by slag shares are hit by the striking elements and thereby burst or broken. Due to the forces prevailing in the housing, the slags are transported to the outside and further processed in the next rotor levels.
  • the housing can be filled, for example, only via the opening 5, so that only the lower two rotor groups are active. But it is also possible to over all filling openings to either produce a corresponding slag stream or, for example, to supply different grits across the different openings. The largest grain size is introduced via the filling opening 3, 4 and 5 then each smaller grains.
  • the Fig. 2 schematically shows a part of a drive axle 11.
  • a striking element 12 is fastened by means of a connecting element 13 to the drive axle 11, so that upon rotation of the drive axle 11, the striking element defines a rotor plane.
  • a slag flow with the volume Vol falls either from a feed opening or a leading rotor coming via a drop height h in the region of the rotor plane defined by the impact element 12.
  • the degree of machining density results. If the granulation of the slags in the volumetric flow Vol is known, the probability of the slag fraction being hit by the impact element 12 results from the height of fall h and the parameters mentioned.
  • Fig. 3 shows in detail the striking element 15 with the bevelled side edge 16.
  • a fixing lug 17 serves to attach chain links 18 to the striker 15 in this way on a drive axle (not shown) to be fastened When the drive axle rotates, the striker 15 flies in a plane around the Focus.
  • the length I of the impact element 15, the width b and the thickness d can be varied.
