Definitions

  • the present invention relates to suction of dust and vapours in a road planer or similar milling machines.
  • the invention refers to a road planer improved with suction and disposal devices for dust, namely the invention refers to a self propelled road milling machine according to the pre-characterising part of claim 1.
  • a known road planer refers to a self propelled milling machine, generally used for removing a portion of asphalt road pavement in order to restore the road with re-deposition of renovated road-surface (repaving).
  • Said crawler tracks or wheels are connected to telescopic columns, which consent the chassis to achieve the correct height and attitude to get the requested milling profile.
  • the material, milled by the drum, is removed by one or more conveyor belts, and finally discharged at the front section of the machine, or at its rear section.
  • the milled material is discharged into a transport vehicle, which precedes the milling machine, whilst in the second case the vehicle follows the milling machine, running backward.
  • Patent EP 0 971 075 A1 foresees to fit a suction hood over the collecting conveyor and to connect said hood with a cyclone followed by a suction ventilator: said cyclone being located in the rear part of the milling machine.
  • Patent DE 102 23 819 A1 foresees the suction of the polluted air from the channel on the collecting conveyor and to convey it into the channel on the loading conveyor by means of the same suction-ventilator.
  • This solution consents to exhaust the air, polluted by dust and vapours, into the atmosphere far away from the operator's platform.
  • the solution suffers the following disadvantages:
  • Patents EP 1 507 925 B1 and US 7,219,964 B2 foresee to suck the polluted air from both the channel on the collecting conveyor and from the channel over the loading conveyor, where:
  • DE 10 2004 007716 discloses a milling machine having a co-located air suction hood that collects dust which is discharged via a duct. The suction power is applied at a point well away from the milling tool.
  • JP 2007138420 discloses a milling machine with an air exhaust passage and a negative pressure means preventing the dust from leaking to the outside.
  • a milling drum (3) is supported by the chassis (1) transversally to the direction of travel, being directly operated by the diesel engine through a mechanical transmission, or by a hydraulic transmission.
  • the crawler tracks (2) are connected to telescopic columns (4), which consent the chassis to achieve the correct height and attitude to get the requested milling profile.
  • the material, milled by the drum (3), is removed by one or more conveyor belts (5), (6) and is finally discharged at the front section of the machine (in an other solution this can be at its rear section).
  • the milled material is discharged into a transport vehicle which precedes the milling machine, whilst in the opposed case the vehicle follows the milling machine, running backward.
  • the milling drum (3) is located inside a drum housing (7).
  • said drum housing (7) is provided with a rear mobile moulder (8), fitted with scraping tools, and with two mobile side plates (9a), (9b), kept in contact with the road surface, and having a floating or a slightly downward forced action.
  • an opening (10) is provided, which consents the milled material to be discharged onto a first conveyor belt (5) (collecting conveyor).
  • Said collecting conveyor (5) is provided at its driven pulley section with a support device (11) (pressure bar), generally sliding over the road surface, in contact with the same.
  • the driving pulley section of said collecting conveyor (5) slides over a support (12), which is part of the machine chassis (1).
  • the frame of the collecting conveyor (5) moves vertically and longitudinally, depending upon the working milling depth.
  • the collecting conveyor (5) discharges the milled material onto a second conveyor belt (6) (loading conveyor) which can be slewed vertically and horizontally to adapt its discharge head (36) to the height and position of the transport vehicle.
  • Each conveyor consists of a mobile rubber belt ring (13), supported in the transport section by "V" shaped rollers (14) and supported by other rollers (15) in the return section.
  • the frame (16) of the conveyor is fitted with side walls (17a), (17b) and with a top sealing mean or cover (18). Said side walls (17a), (17b) support flexible skirts (19a), (19b) in positive contact with the upper surface of the mobile rubber belt ring (13).
  • the milled material (20) is therefore transported inside a channel (21 a, 21 b) enclosed by said side walls (17a), (17b), by said flexible skirts (19a), (19b), by said cover (18) and by said mobile rubber belt ring (13).
  • the road pavement consists of an asphalt mixture also bitumen vapours are produced, due to the high temperature caused by the friction of the cutting tools, so dust and vapours escape from the drum housing and from the conveyor belts and are emitted into the surrounding environment and particularly close to the driving platform (43) with potential health risk for the operator.
  • the health risk is enhanced during milling of a road pavement where aggregates contain silica and/or asbestos fibres.
  • the description of the invention refers to a road planer improved with suction and disposal devices for dust and vapours as for Fig. 3a-3b and Fig. 4 , where the milling drum (3) is located inside a drum housing (7) and where the suction-filtering unit (29) is located at the back of the machine.
  • the suction-filtering unit is represented as mounted on the back of the machine, it is evident that equivalent alterations and modifications will be obvious to one skilled in the art upon the reading and understanding of this specification and the annexed drawings. Thus, it should be understood that the invention is not limited by the description and the annexed drawings, but embraces all such alterations, modifications and variations in accordance with the scope of the appended claims.
  • the invention concerns the fitting of a suction-filtering unit (29) capable to maintain under negative pressure the areas where dusts are produced.
  • Channels (21a) and (21b), respectively identifiable on conveyors (5) and (6), and the effective sealing of the discharge area (22) of the collecting conveyor (5) onto the loading conveyor (6), along with the drum housing (7) constitute one continuous channel or chamber (23).
  • Said channel (23) is closed in its lower section by the walls of the milling drum housing (7), by the rear mouldboard (8) and by the side plates (9a), (9b), whilst its upper section is closed by sealing means, namely one or more sets of overlapped flexible flaps (24) which oppose the entry of external air but do not oppose the flow of the milled material (20).
  • Said flexible flaps (24) slide over the milled material (20) in contact with it.
  • 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 comprises 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.
  • 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.
  • a replaceable dust container (32) consisting of a rigid barrel or of a bag, in the last case properly supported by an internal cage (37), which prevents the bag to be squeezed by the differential pressure between the outside and the inside of the suction-filtering unit.
  • flexible bags are used with a capacity of about 30 kilos and fitted with braces to be easily handled by the operator.
  • Flexible bags can be easily stored on board of the machine, have a low cost and can be economically disposed off along with the recovered dust.
  • the bag Before the bag is released from the collecting hopper (30), it is preferably sealed by a sewing equipment (not shown in the drawings) and left on the road bank for the final collection, said sewing equipment being preferably portable.
  • a sewing equipment not shown in the drawings
  • said sewing equipment being preferably portable.
  • At the discharge head (36) of the loading conveyor (6) some dust is inevitably produced, which however spreads around in the atmosphere far away from the operator's platform (43).
  • a spray bar is provided.
  • Said spray bar 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:
  • Said sealing device (34) being preferably a ring of soft rubber conveniently centred on the vertical pivoting axis of the loading conveyor (6).
  • 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).
  • suction-filtering unit (29) is connected to the chassis (1) of the milling machine by means of movement means (41, 42) which consent to move said suction-filtering unit (29) longitudinally and vertically so as to achieve the following positions:
  • the vertical movement allows the suction-filtering unit (29) movement between transport and working position as well as the bag replacement.
  • the longitudinal movement allows an easy access to the machine as well as to the suction-filtering unit (29) itself.
  • said movement means are two telescopic arms: one telescopic arm (41) performing a longitudinally movement and the other telescopic arm (42) performing a vertical movement.
  • the gradation of the airborne dust also includes particles having a relatively coarse sizes, which do not represent a health risks.
  • the removal and separate disposal of such particles from the dust laden air flow before entering the bag filter takes to the following advantages:
  • a dust pre-separator (44) Fig. 3b can be advantageously interposed between the suction point of the dust laden air and the bag filter (29).
  • the coarse dust particles, recovered by the pre-separator, are discharged by a auger (45) onto the loading conveyor (6), downstream the air sealing device (24), to be included into the milled material (20).
  • the pre-separator (44) of Fig. 9 comprises of a box installed in the ductwork between an inlet (46) and an outlet (47) flange.
  • the sudden expansion of size at the chamber inlet reduces the speed of the dust laden air stream (27a) and the heaviest particles settle down by gravity.
  • a baffle plate (48) causes the air stream to make a sudden change of direction, forcing the intermediate size dust particles to hit the baffle, thus reducing their kinetic energy.
  • the speed reduction also makes said dust particles to settle down.
  • the size of the baffle chamber does not consent a high separating efficiency and the lightest dust particles are carried by the partially cleaned air stream (27b) toward the bag filter inlet.
  • An auger (45) is fitted at the bottom of the pre-separator collecting hopper (49) to seal it and to discharge the recovered coarse dust onto the loading conveyor (6).
