Definitions

  • the invention relates to a fastening system for screening machines and / or setting machines for attachment of replaceable Siebbelagsegmenten and / or interchangeable wear protection elements in or on a screening machine with at least one Siebbelagsegmente receiving and / or wearing the wear protection elements vibration-sensitive swing frame, wherein the Siebbelagsegmente and / or wear protection elements by means of retaining strips are attached to the swing frame.
  • the invention relates to a screening machine with such a fastening system.
  • the object of the invention is to overcome these disadvantages and to provide a fastening system for screening machines and / or setting machines for attachment of replaceable Siebbelagsegmenten and / or interchangeable wear protection elements, which allows easy disassembly and assembly of Siebbelagsegmenten and / or wear protection elements on a screening machine.
  • screening machine and setting machine are used interchangeably.
  • the invention thus carried the attachment of the Siebbelagsegmentes and / or the wear protection element on the swing frame by a magnetic connection of the retaining strips on the screening machine.
  • To the Siebbelagsegmente and / or wear protection elements after reaching the To replace wear limit thus requires only the solution of the magnetic connection of the retaining strips of the swing frame of the screening machine and after replacing only the attachment of the retaining strips at the appropriate positions on the swing frame.
  • the magnetic holding forces are to be selected so that a vibration-resistant connection of the retaining strips is created with the swing frame of the screening machine.
  • the swing frame is vibration excitable by a corresponding drive, ie it can be set in defined vibrations.
  • a vibration-proof connection of the magnetic connection thus means that the retaining strips are securely fixed even with a vibration excitation of the swing frame with it applied by means of the screening machine to be screened material and not dissolve in the operation of the screening machine.
  • the Siebbelagsegmente and / or wear protection elements may have an axisymmetric and / or rotationally symmetrical arrangement of several retaining strips and thus magnets and / or a rectangular or a square basic shape.
  • each retaining strip on one or more magnets which are each fixed to a corresponding ferromagnetic counterpart on the swing frame of the screening machine.
  • the magnetic connection of the retaining strips with the swing frame can be done directly or indirectly.
  • the swing frame has for receiving the retaining strips corresponding bearing areas for magnetic attachment of the retaining strips.
  • This means that the swing frame has support areas, the geometric design and positioning is carried out such that the magnets can make a magnetic connection.
  • at least the bearing areas of the oscillating frame are ferromagnetic, preferably the oscillating frame consists entirely of ferromagnetic material.
  • the retaining strips may be formed in particular as elongated strips.
  • the frame of the screening machine, which receives the retaining strips can be formed by X-profiles and / or C-profiles and / or U-profiles and / or T-profiles and / or KR-profiles and / or angle profiles.
  • such retaining strips may also be attached to side panels of screening machines and serve the attachment of lateral wear protection elements.
  • These side parts may, for example, be vertical boundary walls above the sieve bottom.
  • a particular advantage of the invention is therefore that the fastening system for screening machines for attachment of replaceable Siebbelagsegmenten and / or interchangeable wear protection elements can be retrofitted by the attachment of retaining strips by means of magnets in existing screening machines, since the retaining strips magnetically to the original for the Siebbelagsegmente and / or wear protection elements provided recordings and mounting locations can be attached.
  • a plurality of retaining strips form a receiving frame, in which at least one Siebbelagsegment and / or wear protection element rests, wherein the receiving frame has one or more magnets for magnetic connection of the receiving frame with the swing frame.
  • the Siebbelagsegmente and / or wear protection elements are positively and / or non-positively in the retaining strips.
  • each Siebbelagsegment and / or wear protection element forms a positive connection and / or a frictional connection with one or more retaining strips.
  • the sieve bottom can also be formed by a single, one-piece sieve lining segment.
  • the invention is not limited to use with a sieve tray formed of multiple sieve tray segments, although this is a preferred embodiment.
  • the magnets are positively connected to the retaining strips, in particular, the magnets can eino in dovetail grooves in the retaining strips.
  • the magnet (s) may have at least one undercut.
  • the retaining strips have a plurality of in particular equidistant, in particular along side edges of Siebbelagsegmente and / or wear protection elements arranged magnet.
  • the magnetic holding force can be increased and applied uniformly, for example along the edges of the Siebbelagsegmente and / or wear protection elements to be fastened.
  • the Siebbelagsegmente and / or wear protection elements are formed by polyurethane.
  • the Siebbelagsegmente may also be formed by perforated plates, in particular, each Siebbelagsegment be formed by a perforated plate with a polyurethane layer injected thereon.
  • the coating applied to the perforated plate can have a different, in particular smaller, mesh width than the perforated plate serving as carrier.
  • the swing frame has an inventive fastening system.
  • several Siebbelagsegmente form a sieve tray.
  • adjacent Siebbelagsegmente can each form a positive connection and / or positive engagement, in particular have a tongue and groove connection.
  • a plurality of Siebbelagsegmente form a sieve tray, wherein the last in the transport direction of the Siebgutes Siebbelagsegmente are supported in the transport direction end against transverse stop elements, in particular against a continuous transverse stop bar support.
  • the Siebbelagsegmente with the perpendicular to the transport direction transverse stop bar form a frictional connection and / or a positive connection, in particular a tongue and groove connection.
  • Sieve trays are usually placed at an angle to the horizontal, wherein the screenings to be processed are applied to the sieve bottom at the geodetically higher end of the sieve tray and removed via the geodetically lower end of the sieve tray.
  • the last Siebbelagsegmente supported in the transport direction of the screenings end against transverse stop elements.
  • the arrangement of these transverse stop elements is thus transverse to the transport direction of the screenings.
  • transverse stop elements in particular a transverse stop bar receiving the thrust forces, can be fastened to the frame or formed by the frame which accommodates the screen segments themselves.
  • the transverse stop elements can be further formed by arranged at the appropriate location of the frame adapter.
  • several Siebbelagsegmente form a sieve tray, wherein the Siebbelagsegmente laterally in the direction perpendicular to the transport direction of the material to be screened running parallel to the transport direction Lfitsanschlagiana, in particular Lfitsanschlagangn support, in particular that the Siebbelagsegmente form parallel to the transport direction LNicolsanschlagangn a frictional connection and / or a positive connection, in particular a tongue and groove connection.
  • the longitudinal stop strips extend on the sides of the sieve bottom parallel to the transport direction of the screenings.
  • the longitudinal stop strips can be attached to the frame or be formed by the retaining strips which receive the sieve segments themselves.
  • a screening machine with a swing frame for receiving a plurality of Siebbelagsegmenten to form a sieve plate, wherein the swing frame has a Siebbelagbefest onlyssystem according to the invention.
  • FIG. 1 shows a schematic perspective view of a screen formed from several Siebbelagsegmenten 10, 20 Siebêts a screening machine.
