Definitions

  • Screening device with a first oscillating body comprising first cross members and a second oscillating body including second cross members, the first cross member and second cross member being arranged alternately and preferably transversely to a screen surface and each having clamping devices via which screen linings forming the screen surface between a first cross member and a second Cross members can be clamped and the first and second screen bodies can be made to vibrate relative to one another in order to compress and expand the screen linings alternately.
  • Such screening devices are also referred to as flip-flop screening machines or flip-flop screening machines. They are characterized by the use of flexible screen linings that are alternately compressed and stretched and are used wherever conventional screening devices with rigid screen linings clog and stick.
  • each screen lining of the screen surface which is built up by several screen linings, is clamped between two cross members that usually run transversely to the screen surface.
  • One of these two cross members is part of a first oscillating body, the other cross member is part of a second oscillating body.
  • the two vibrating bodies vibrate relative to each other and out of phase, which causes the compression and expansion of the screen linings.
  • the connecting component is usually a sieve cheek of a sieve box.
  • One screen box is resiliently and thus swingingly mounted on a machine foundation, while the other screen box is supported resiliently or elastically on the screen box mounted on the machine foundation.
  • a drive usually an imbalance drive, moves one of the sieve boxes and so that a vibrating body vibrates so that the other screen box also vibrates.
  • the resilient or elastic mounting of one screen box on the other is coordinated in such a way that the two screen boxes (oscillating bodies) oscillate out of phase and in opposite directions.
  • Such a screening device is for example from DE 1 206 372 known.
  • This consists of two oscillating bodies in the form of sieve boxes.
  • a vibrating body each comprises a screen box and cross members rigidly connecting the two screen cheeks of the screen box.
  • one oscillating body is resiliently mounted on the other oscillating body and is made to vibrate by means of a drive. Both oscillating bodies are set up on a foundation in a resilient manner.
  • this object is achieved in a screening device mentioned at the outset in that a supporting structure is provided that accommodates the two oscillating bodies and the first and second oscillating bodies can be made to vibrate relative to the supporting structure.
  • the oscillating masses can be kept low.
  • the supporting structure is a stationary supporting structure. While it is basically conceivable to arrange the supporting structure on a foundation in a resilient manner in order to provide the entire screening device with a fundamental vibration that contributes to the conveyance of the material to be screened along the screen surface, a stationary supporting structure contributes in particular to saving drive energy, since the drive The energy required can only be used to set the two oscillating bodies in vibration.
  • the oscillating bodies can be designed to be correspondingly compact and light.
  • the machine weight can also be reduced by up to 40% with a stationary support structure due to the lower overall height, thinner sheet metal thicknesses and smaller drives, so that the manufacturing costs and thus the acquisition costs are also significantly lower, not to mention the associated savings in resources.
  • a stationary supporting structure also enables several flip-flop screening machines to be arranged one above the other (multi-deck machines) by simply stacking the individual supporting structures on top of one another. This also improves the ability to retrofit a further screen deck.
  • a single drive is provided, by means of which both oscillating bodies can be made to oscillate.
  • Such a construction is characterized by a particularly simple, inexpensive structure that is particularly light, but requires a relatively precise coordination of the masses of the two oscillating bodies on one another and the resilient and elastic elements used, especially when it comes to the above-mentioned To achieve mass balance of the vibrating body.
  • the drive is arranged on one of the two oscillating bodies and the other oscillating body is resiliently coupled to the drive, preferably via a spring element or elastically .

  • a separate drive can be provided for each oscillating body, by means of which the respective oscillating body can be caused to vibrate.
  • the oscillating bodies can thereby be easily controlled and the coordination of the oscillations of the two oscillating bodies to one another is easier to set or correct, in particular the phase offset.
  • This variant is also less sensitive to differences in the masses of the two oscillating bodies.
  • the two drives can be attached to the support structure in a simple manner and thus do not influence each other.
  • each of the two oscillating bodies can be coupled to one of the two drives via a spring element or elastically.
  • the two drives can be synchronized and operated offset by about 180 °.
  • the drive or drives are preferably eccentric drives.
  • the use of eccentric drives to set an oscillating body of a flip-flop screening machine to oscillate is known in principle. In combination with the stationary support structure and the vibrating bodies that vibrate relative to it, however, it is possible to dimension these very small and therefore economical in terms of energy use, since the support structure does not also have to be made to vibrate.
  • oscillating bodies as such can each be designed in a manner known per se, ie. consist of cross members which are connected to each other in their respective end areas via push rods, which in turn can be coupled to the drive or drives.
  • the mounting and coupling of the oscillating body on the supporting structure can be done, for example, via the push rods. It can be provided that the push rods of each of the two oscillating bodies are mounted on the support structure via resilient or elastic elements or that the push rods are on the one hand mounted on the support structure via resilient or elastic elements and are simultaneously coupled to one another via resilient or elastic elements.
  • the mounting and coupling on the support structure or on the respective other oscillating body takes place via thrust elastic rubber blocks known per se, which allow oscillation in a coupling axis, whereas oscillations in the direction of other axes are negligible.
  • the coupling axis runs essentially parallel to the longitudinal axis of the push rods.
  • a first cross member of the first oscillating body is connected on the one hand to an adjacent cross member of the second oscillating body by means of a drive motor and on the other hand to the support structure via a resilient element, preferably a spring element or an elastic element connected is.
  • a resilient element preferably a spring element or an elastic element connected
  • the fundamental oscillation which occurs due to the resilient mounting of the screening device on a machine foundation, always contributes to the conveyance of the screened material, it may be necessary, especially in the case of a stationary supporting structure and depending on the screened material, that in In the operating state, the inclination of the screen surface relative to the horizontal is between 5 ° and 25 °, preferably between 15 ° and 20 °, in order to convey the material to be screened over the screen surface in accordance with the requirements.
  • the screen surface has at least two partial screen surfaces. This variant allows at least two separating cuts on one screen deck.
  • Each partial sieve surface can have, preferably vertically protruding, sieve surface cheeks protruding from the sieve surface counter to the feed direction of the sieved material, in order to minimize the loss of sieved material.
  • each screen deck having its own drive and oscillating body, which means that the oscillation amplitude or mat dynamics can be set and regulated separately for each screen deck without the oscillating bodies of one screen deck being influenced by the oscillating bodies of another screening deck.
  • Another variant of the invention provides the possibility of securely attaching system components to the stationary support structure, for example by flanging them.
  • This can be, for example, system components that supply and / or discharge material. But it is also possible to attach system components for sealing in order to make the sieve device dust-tight.
