Definitions

  • the present invention relates to a machine for compaction of solid materials.
  • the main object of the present invention is to offer a machine for compaction solid materials of simple manufacture, economical, reliable and operational with low energy expenditure.
  • the advantages which derive from the present invention basically consist of what is possible work with materials of a different nature, otenant compaction with a large reduction of volume so as to obtain a finished product with optimal cohesion characteristics and suitable for different forms of related employee the nature of the materials treated; that a machine according to the invention is manufacturing simple, economical and reliable even after a while extended use; that spending energetics are greatly reduced; that it is possible carry out any warming or cooling of materials during compacting, with a reduction in the time required to complete the processing; that the material is can be shaped so as to obtain "dumplings", that is to say small compact blocks, with cross-section either circular than polygonal in length volue.
  • fig. 1 shows a partial view in perspective of a machine according to the invention
  • fig. 2 shows a front view of the machine of fig. 1
  • fig. 3 represents a partial plan view of a machine cylinder of fig. 1
  • fig. 4 represents a detail of the cylinders of the machine fig. 1 in exercise position
  • figs. 5,6,7, and 8 represent alternative forms of realization of the means for the subdivision of product in treatment in length elements predetermined.
  • a machine for compaction of solid materials in accordance with the invention comprises at least one pair of counter-rolling hollow cylinders (1,2) side by side and engaged by means of helical teeth (10,20) respectively, so as to compress the materials (M) supplied in correspondence with the setting area (Z) of the teeth (10,20) by the opposite direction of the cylinders (1,2) around the respective axes (a-a): each said cylinders (1,2) being provided, in correspondence of the grooves (G) delimited by the teeth (10,20), of a plurality of through holes able to delimit corresponding channels (100) to through which the shaping materials are forced to go through compression effect exerted by the teeth (10,20) taking the form of cylindrical bars (b) of section basically corresponding to the output channels (100) and oriented towards the cavities (CA) internal of the cylinders (1,2).
  • the external profile (EG) of the grooves (G) of cylinders (1,2) is shaped convex, with the convexity facing outwards and, in the same way, the external profile (ED) of the front of the teeth (10,20) of the cylinders (1,2) is convex shape, with the convexity facing outside.
  • each groove (G) is arranged so that the plan projections of the respective centers result aligned on a line segment forming a predetermined angle ( ⁇ ) relative to the axis of rotation (a-a).
  • Said angle ( ⁇ ) can be advantageously chosen based on the condition that the plane distance (d) between the center of the holes (100a, 100b) more distant from each other is equal to the diameter, constant, of the entry section (I) of the holes same.
  • Said cylinders (1,2) are suitably provided an envelope, except that in the grip area (z) respective teeth (10,20).
  • each channel (100) is in truncated cone with the walls converging towards the exit.
  • the opening angle of the truncated cone can be, for example example, equal to 60 °.
  • the outlet section of the channels (100) can be either circular than polygonal.
  • a fixed body (3) developed orthogonally to the axes of rotation of the cylinders mentioned above (1,2) and with an end facing the teeth grip area (Z) (10m20), which body (3) has two edges (30) converging towards said end, so as to operate, during rotation of the cylinder (1,2), a shaving action, i.e. cleaning the external surface of the teeth (10.20) by grinding the material which has remained strangled at the treatment and forcing him to enter between the openings of the teeth which follow - according to the line of rotation - and so allowing circulation.
  • said means include a truncated cone shaped body (4) with the minor base facing outwards from the machine and housed in the cavity (CA) of the cylinder, fixed coaxially on the same shaft, so that turn solidly with it.
  • the bars (B) outgoing from the channels (100) are intercepted by the surface of the body (4) and thus sectioned in basically length elements corresponding to the distance between the section of exit of each channel and said surface, by effect folding and the consequent loss of cohesion derived from it.
  • said means include a fixed spatula (5) arranged in the cavity (CA) of the shaped and folded cylinder so as to operate either the cutting of the bars (B) outgoing from the channels (100) and carried by the cylinder in rotation, that routing to the external elements that have been cut.
  • a fixed spatula (5) arranged in the cavity (CA) of the shaped and folded cylinder so as to operate either the cutting of the bars (B) outgoing from the channels (100) and carried by the cylinder in rotation, that routing to the external elements that have been cut.
  • the means of subdivision of the bars (B) include a cylinder (40) internal to the toothed cylinder (1,2) and provided with several channels (41) where the axes form a predetermined angle with the axes of the holes (100) correspondents of the cylinder (1,2).
  • Said cylinders (1,2) can be conveniently provided with longitudinal channels (6) almost provided in correspondence of one or more of the gorges (G) to allow the circulation of heating or cooling fluids which can be supplied by means of an installation not shown for simplicity in figures of the attached drawings.
  • the machine described is capable of working solid materials of different nature, such as example food substances and for the production of animal feed, destroyed, industrial and similar wastes.
  • the product finished can be advantageously used as alternative fuel for the supply of suitable burners, already known per se.
