Definitions

  • the invention relates to a plan sifter for the mechanical separation of piece goods of different piece or grain sizes into selectable size classes.
  • a plan sifter for the mechanical separation of piece goods of different piece or grain sizes into selectable size classes.
  • Such a plan sifter is known to be equipped with a screen box inclined more or less against a horizontal comparison plane, in which one or more screens with different mesh sizes are inserted.
  • the screen box has at least one raw material inlet. At least one material outlet is then provided for the screened material.
  • the sieve box carries out an oscillating movement, as a result of which the material subjected to the sieving moves from the inlet to the outlet or the outlets of the sieve box.
  • the invention seeks to remedy this.
  • bie invention as defined in the claims, particularly in the characterizing part of claim 1 or claim 2, solves the problem of a plan sifter having a simplest possible mounting of the screen box, as well as extremely simple Siebkastenantrieb even for relatively g horses Siebkastenkombinationen of very powerful plansifters to create by the drive mediating the oscillating movement also serves at least partially as a suspension, the propagation of the oscillating movement to the environment of the plan sifter system is prevented by compensating for the vibrations in the system itself.
  • Vibration compensation is achieved, which is further improved by using flyweights arranged on the shafts as antagonists with regard to the respective instantaneous movement of the sieve boxes.
  • the plan sifter according to the invention has the further advantage that the guiding of the end or ends of the sieve boxes facing away from the respective shaft can be carried out as simply as possible by means of suspensions, supports, bearings or the like, because seen in the longitudinal direction of the sieve boxes Longitudinal as well as transverse and
  • Transverse movement to both composite movement of the respective distal end of the screen box is determined by the drive from the drive by the desired screen material run. Further advantages are also mentioned in connection with the description of the figures. Seen overall, the invention is characterized by simplification, cheaper, improvement in quality and the desired freedom from maintenance, as well as by error elimination with respect to vibration propagation, while simultaneously improving the smoothness of even large plan sifter units. By closely interacting the drive device with the vibrating parts while simultaneously using the drive device as an essential holder for these parts, a new path in plan sifter construction is taken, which not only simplifies but also makes the plan sifter more compact.
  • This plan sifter contains two screen boxes 1 and 2 arranged one above the other, an upper screen box (1) and a lower screen box (2). They are designed as closed sieve boxes and have a similar design. Corresponding parts of the sieve boxes are designated with the same reference numbers below.

  • this body 145 deflects these partial flows to the side. Since there are no side walls on the bottom of the sieve unit 105 in this area of the discharge section 120, the partial flows of the fine fraction from this sieve unit 105 fall out into the lateral outlet channels 150 and 151.
