Definitions

  • the present invention intends to remedy these drawbacks by proposing a device for cleaning a beach or the like for which it is possible to selectively remove the polluting product with respect to the sand and thus, to considerably reduce the amount of sand transported. and facilitate the processing of the product.
  • the invention therefore makes it possible to significantly reduce the cost of such an operation.
  • a device of this type is known from European patent application No. 0031 610 in which an endless strip material is applied without sliding on the sand and is wound around return cylinders to be freed of the collected pollutant which is collected in a bin.
  • the invention therefore consists in an improvement of this type of device, consisting of a material in the form of an endless band, comprising means for attaching the polluting product to at least one of its faces, by a frame for rotationally supporting means for supporting and winding said strip by a cleaning device carried by said frame means and maintained in contact with the endless material along a fixed line with respect to the frame, and by a device for recovery and evacuation of the plots of product collected and detached by the cleaning device.
  • the above-mentioned support and winding means is constituted by a single cylinder on which said strip is applied.
  • this device comprises a member for rotating the cylinder at an adjustable speed and means for adjusting its application pressure on the ground.
  • the recovery device comprises a main part located in the vicinity of the lower rear part of said cylinder and an auxiliary part for recovering the product spontaneously detaching from the collecting material located in the vicinity and under the rising rear part of the cylinder between said main part and said cylinder.
  • Said main part of the recovery and evacuation device is in the form of a conveyor belt driven parallel to the axis of the cylinder extending longitudinally beyond one of the ends of the cylinder while the aforementioned auxiliary part is a second conveyor belt driven in a direction substantially orthogonal to the axis of the cylinder in the direction of the aforesaid first conveyor belt.
  • the above-mentioned cleaning device is located at the rear of said cylinder and above its diameter ho rizontal. It is advantageous for use, to provide the above-mentioned frame provided with means for coupling it to a towing vehicle at the rear and in lateral offset relative to the latter.
  • the abovementioned collecting material may be either a strip of flexible plastic material resistant to hydrocarbons, provided on its outer face with regularly distributed protuberances, or a strip of an openwork product deployed in mesh.
  • the device according to the invention is essentially constituted by a material 1 in endless band, wound around a cylinder 2, rotatably mounted on a frame 3.
  • This material may be a synthetic mat, or other flexible plastic materials resistant to hydrocarbons, having on its outer face 4, protuberances whose height, surface density and shape are determined (by tests) so that they constitute effective means for attaching the viscous pollutant (hydrocarbons) generally in the form of relatively flat amalgams. It can also be a grid made, for example of expanded metal whose meshes constitute polygonal cells for retaining the pollutant. Finally, it may consist of a level covering of the carpet or synthetic grass type, the bristles of which constitute said retaining means.
  • said material is applied to the ground (generally a beach of sand) by successive surface elements, the cylinder being rolled without or with a slight sliding on the sand.
  • Each surface element is therefore brought into contact with the polluting product which is in its path under a certain pressure (corresponding to the weight of the device possibly increased by an additional application force) for a time which depends on the speed of movement of the device.Under this pressure and during this contact time, the polluting product clings to the strip by its retaining means, causing only a thin thickness of the underlying sand. Outside the polluted area, the amount of sand collected is negligible.
  • the cleaning device 5 will be adapted to the strip. It could be a rotary brush having flexible metal fingers rotating in direction B for a strip with protuberances.
  • the contact zone 8 between the strip and the brush will be located at the rear and above the horizontal diameter of the cylinder 1, so that the brushed product is projected and falls onto the conveyor belt 6.
  • a strip of perforated collecting material such as expanded metal
  • An external brush or doctor blade can be envisaged, associated with the preceding internal device.
  • An auxiliary recovery device 9 also shown in the form of an endless conveyor, placed in the vicinity of the rising part of the cylinder 1, will also be provided for collecting the plots of product which would detach from the collecting strip 1 under the effect of the thinker. While the conveyor belt 6 is driven in a movement parallel to the axis of the cylinder 1, the endless conveyor 9 is driven in a movement substantially orthogonal to this axis. In a simplified form of the invention, this device could be a simple curved blade parallel to the generator of the collecting cylinder forming a sliding ramp of the product discharged onto the strip 6, by the rotation of the cylinder 1.
  • the device according to the invention applies very particularly to viscous hydrocarbons deposited on the surface on beaches. These are therefore superficial, little contaminated by other foreign elements under the effect of the mixing of successive tides. It is also advisable not to encrust them in the sand before their collection.
  • the device according to the invention is adapted to be placed laterally (Figure 2) at the rear of a tractor. All of the rollers 1 of the brush 5 of the recuperators 6 and 9 are integral with the frame 3 which can be harnessed to the three rear points of a tractor 10 (FIG. 2) in offset mode, as is thundered in the field of machines.
  • the conveyor 6 extends beyond one end of the cylinder 1 to return behind the tractor 10. With this arrangement, it is thus ensured that the tractor 10 will travel on already cleared terrain .
  • the cylinder 1 will be rotated by means of a drive member supplied by a power source (for example hydraulic) belonging in known manner to the tractor.
  • a power source for example hydraulic
  • a device for cleaning the cleaning device itself which can, for example, consist of a fixed comb 11, integral with the cover 7 for the wire brush, as well as another device 12 for removing dirt from the coating. with comb-like protuberances located just behind the line of contact of the teeth of the brush with the protuberances.
  • the evacuation device 6 will be extended by a conveyor belt adapted to convey the polluting product into a receptacle according to the tractor 10 in its evolution on the beach.
  • the invention finds an interesting application in the field of depollution.
