  • Said channel (23) and the drum housing (7) are kept in depression through one or more hoses (27) connecting it to the suction-filtering unit (29), said hoses (27) preferably being flexible. It will be apparent to the experts in the art that said hoses (27) could be a fixed duct or a fixed duct with flexible hoses on one or on both ends or in some intermediate positions to allow the movement of the adjustable devices of the machine.
  • the suction-filtering unit (29) basically consists of a set of filtering elements (26) (pockets, hoses, cartridges), a suction fan (25), a filtering media cleaning system (35). Said fan (25) sucks the air polluted by dust and vapours from said channel (23) and drum housing (7) through the battery of filtering elements (26). Said filtering elements (26) are contained in an enclosed housing (28) fitted with a collecting hopper (30) in its lower section.
  • Said suction-filtering unit comprises: a bottom dust collecting hopper (30), the set of filtering elements (26), the cleaned air outlet cowling (31), the suction fan (25), the compressed air contra-flow cleaning system (35).
  • the abrupt reduction of the polluted air speed at the enter into the collecting hopper causes the coarse dust particles to drop down without colliding against the filtering media thus reducing the risk of damage to a minimum.
  • the filtering elements (26) oppose a resistance to the passing through air flow, which results in a pressure drop through the filtering media. This forces the dust to be retained on the external surface of the filtering elements (26), causing a slight compression of the dust and its agglomeration.
  • the dust cake itself contributes to increase the pressure drop through the filtering elements, thus improving the dust agglomeration.
  • An automatic cleaning system (35) periodically pulses blows of compressed air in contra-flow to detach the dust cake and makes it to drop into the bottom collecting hopper (30). It will be apparent to the ones skilled in the art that different but equivalent configurations can be used to clean said filtering elements (26), such, by way of example, vibrating devices shaking them, or a combination of different known cleaning systems. The negligible amount of dust, still remaining in the filtered air flow, does not affect in any way the efficiency of the system and the work continuity of the machine.

  • Said spray bar (40) consists of a set of water atomizing nozzles, having the scope to further support the dust agglomeration and its fall.
  • the suction efficiency depends upon the sealing degree of channel (23).
  • the sealing media of the critical discharge area (22) of the collecting conveyor (5) onto the loading conveyor (6) must be efficient enough so as to maintain the channel (23) depressurized at any position of conveyor (6) in respect of conveyor (5) and at any position of conveyor (5) in respect of the machine chassis (1 ).
  • the sealing means of the discharge area (22) of the collecting conveyor (5) onto the loading conveyor (6) are preferably made as schematically shown in Fig. 7, where:
  • the sealing device (33a - 33b) compensates the vertical slew of the loading conveyor (6)
  • the sealing device (34) compensates the horizontal slew of the loading conveyor (6).
  • Said sealing device (34) being preferably a ring of soft rubber conveniently centred on the vertical pivoting axis of the loading conveyor (6).
  • the suction, supported by the ventilator (25), produces a depression inside the channel (23), which causes a continuous intake of external air and prevents the polluted air from escaping.
  • Advantageously said sets of flexible sealing means (24) applied on the loading conveyor (6) are made of a plurality of closed vertical straps in which each strap overlaps with its border the adjacent one. In this way the advancing material on the continuous belt does not create openings between said straps deflected upwards by the variation in size of the continuous advancing material (20).
