Definitions

  • the present invention relates to a machine for the compression of a bulky mass, so as to form an elongated dense body, which machine comprises a space conically tapering towards an outlet opening and a driven screw arrangement arranged centrally in the space, wherein said screw arrangement comprises a rear feed screw with screw threads and a front compression screw with screw threads and wherein the screws are rotatable at mutually unequal speeds of rotation.
  • the known machine described here functions well in association with waste of a more or less easily sliding character, rarely or never, on the other hand, with dry bulky refuse masses of the type of waste paper, especially plastic-coated waste paper of the type which occurs in the manufacture of packing laminate for so-called non-returnable packages for fluid contents.
  • dry paper waste to effective form-stable fuel briquettes with he help of the known machine of the screw type has been, therefore, either to eke outthe paper with waste material of the more easily sliding kind and/or to add water in order to wet and thereby soften up the paper and transform it into a more appropriate and easily processable consistency.
  • the machine 1 comprises mainly three machine sections, namely a feed-in section 3, an active working section 4 and a feed-out section 5, which are joined together to a machine unit which may be supported on a stand 6.
  • the feed-in section 3 of the machine 1 comprises a box 9 open at the top which is limited by a horizontal bottom wall 7 and substantially vertical side walls 8 to receive and collect waste paper 2 supplied from above which is to be compressed.
  • the box 9 is connected through a hole provided in the front (lefthand) side wall 8 of the box with a conically tapering compression space 10 in a housing body 11 of the active machine section 4 arranged against this side wall.
  • a corresponding hole is provided for a hollow driving shaft 12 supported in the hole in a rotatable manner for a feed screw 13 located in the lower part of the box, which has a rear screw section 13a located wholly in the box 9 with screw threads 14 of mutually equal pitch, and a front screw section 13b extending at least partly into the conically tapering space 10 comprising screw threads 16 with a pitch successively diminishing towards the space 10.
  • a driving shaft 17 for a compression screw 18 Centrally inside the hollow of the driving shaft 12 is supported in freely rotatable manner a driving shaft 17 for a compression screw 18 arranged wholly inside the said space 10 in a straight line in front of the feed screw 13, with screw threads 19 whose pitch decreases successively towards the outlet opening 20 of the space 10.
  • the driving shafts 12 and 17 can be driven in a manner known in itself with the help of a suitable gear drive arrangement by means of one and the same motor (not shown), and in accordance with the invention it is important here that the transmission of power between the motor and the shafts 12 and 17 is adapted so that they can be driven at speeds of rotation freely adjustable in relation to each other.
  • the shaft 17 for the compression screw 18 is adapted to be driven at twice the number of revolutions as the shaft 12 for the feed screw 13.
  • this space has a feed-in region 21 facing towards the box 9 with a somewhat larger taper than the front zone of the space 10, diminishing conically towards a more acute top angle.
  • the space 10 preferably has surface irregularities promoting the feed of the waste paper 2 in the form, for example, of parallel,longitudinal grooves or ridges 23 spaced uniformly around the inner wall 22 of the housing body 11 delimiting the space.
  • the feed-out section 5 of the machine 1 finally comprises a hollow, mainly cylindrically shaped housing body 24 arranged against the housing body 11 and located so that the axial, cylindrical cavity 26 of the housing body 24 constitutes a direct continuation of the outlet opening 20 of the conical space 10.
  • the machine 1 in accordance with the present invention described above operates in the following manner.
  • the shafts 12 and 17 are driven via a suitable power transmission arrangement (e.g. a gear drive of known type) so, that the compression screw 18 is rotated at a speed (e.g. 882 rpm) which is approx. twice as high or even higher still than the corresponding speed (e.g. 411 rpm) for the feed screw 13.
  • a suitable power transmission arrangement e.g. a gear drive of known type
  • the free space between the feed screw 13 and the inner wall of the housing body 11 successively diminishes in the direction in towards the space 10 because of the conical tapering of the feed-in zone 21,the bulky mass of paper waste thus fed will be subjected to a certain precompression during the passage through the feed-in zone 21.
  • the paper waste thus advanced and precompressed by the feed screw 13 through the feed-in zone 21 is advanced further through the space 10, with the help of the compression screw 18 arranged in front of the feed screw 13 and wholly in the conical space 10, into the cylindrical feed-out cavity 26 of the housing body 24 through the outlet opening 20.
