Definitions

  • the invention refers to the field of the machines used in the treatment of the aggregate materials with the purpose to recover meaningful fractions of them, particularly it refers to the machines able to separate, the crushed stone aggregate and assimilated to weight specific superior to the 1300 kg/mc, the light pollutants what paper, wood, plastics, cans, etc.
  • Purpose of the present invention is that to realize a combined machine, easily adaptable on fittingses of treatment and recycling different, automatic, to double pneumatic action, essentially constituted by a vibrating distributor connected to a regulating blowing, a net ribbon connected to an suction device, a ribbon conveyor and elements of unloading and recovery, in degree to effect with best efficiency in comparison to the known types, the selection of the crushed stone aggregates and the separation of the light parts from them.
  • the vibrating distributor consists of a rectangular container tray supported by large springs (2) attached to the frame (3) animated by a vibratory motion and has a pierced base for around three quarters of its length,
  • the material to be treated in precedence submitted to shattering, ferritization and granulation so that treated of a specific particle size ot greater than 100 mm.
  • the distributor (1) In proximity of the three quarters of his length, the distributor (1) has a rung (4) that carries the distributor surface to a lower level (5), this time with no pierced surface, where the material opportunely stratified curtains to fall.
  • the air is blown by an electric fan (7) positioned in the lower part of the machine which uses a flexible tube (8) to send the air to a fixed, slotted tube (9) that is an integral part of the distributor (1).
  • the light fraction of aggregate materials in suspension sort object of an action of lifting subsequently comes through aspiration.
  • a pipe (10) connected to an electric fan (11), positioned between metal mesh conveyor belt lines (12), assembled crosswise and directly above the surface (5), carries out a suction action on the light parts, already blown towards the belt mesh (12), so that these meet the lower mesh of the rotating belt (12) and are dragged and left to fall, and then collected in a container (13).
  • any finer pollutant particles cross through the belt mesh (12) and are carried to a cyclone (14), where they are brought down and collected in a specific container (15).
  • the mesh of the belt (12) is continually cleaned by the pollutant particles that stick to the mesh are blown of by the air, carried away by an air diversion and left to fall into the container (13).
  • the heavy fraction of aggregate completely cleaned from dust and light pollutants falls onto the conveyor belt (16) situated below and longitudinally to the machine and is recovered for use.
  • the invention reaches the preceded purposes, allowing a rational treatment of the results materials so that to select and to recover in optimal way the crusched stone aggregate cleaned from light pollutans; in fact under the combined action of the gravity, of the inertia of the aggregates, of the carry and of the due maintenance to the flow of air, the various constituent bodies the aggregate are forced to effect diversified trajectories making an effective discrimination and a differentiation so possible according to the density, of the coefficient of form and the dynamic inertia of the single constituent heterogeneous bodies the aggregate.
  • the machine is well protected from integrated panellings so that to avoid every dispersion of dusty air in the environment.
