Definitions
- the invention relates to a method and apparatus for the recycling of bituminous materials, more in particular bituminous roofcovering materials .
- bituminous roofing materials which are comprised of bitumen or tar with possible inlaids such as polyester fleece or glass fleece or -fabric and such like, with slate chippings and such like, and with possible other components forming roofing materials such as adhering or not adhering insulation materials formed by polyurethane, polystyrene, mineral wool and such like, by reducing the bituminous or tar containing materials, heating and sorting these, in such a way that the bitumen component in the bituminous materials melts, after which the bitumen and the other components forming the roofing materials are seperated from each other. After sorting, reducing and melting the material is sieved and sorted.
- the known applied methods require much energy and are rather cumbrous.
- the method according to the invention which comprises bringing the bituminous materials into a vessel and melting the bitumen component in the bituminous materials in the vessel, is characterized in that the bituminous materials in the vessel are placed in a seperate container for bituminous materials, while the bitumen and the other components forming the bituminous materials are seperated from each other in the container by means of the application of a force onto the bituminous materials, such as a pressure force or a centrifugal force which is brought to bear on the materials.
- a force onto the bituminous materials such as a pressure force or a centrifugal force which is brought to bear on the materials.
- the bitumen and the other components forming the bituminous materials are seperated from each other by pressing or pushing the materials together in the container.
- bitumen and the other components forming the bituminous materials are seperated from each other in the container by centrifugation of the materials.
- the container with the pressed or pressed together or centrifuged components is lifted or hoisted out of the vessel.
- the invention further relates to an apparatus for applying the method, which apparatus is formed by a vessel for receiving the bituminous materials, with means
- bitumen and the other components forming the bituminous material are seperated from each other.
- the container is provided with means for pressing or pushing the bituminous or tar 25 containing materials together in the container, while these means according to another charateristic are formed by a press or pressure plate, which is movable in the container in the direction of a part of the container.
- the 30 container is formed by a base plate, onto which the bituminous materials can be placed, and a press or pressure plate provided at a distance from the base plate, which press or pressure plate is movable in a direction towards and away from the
- the container is formed by a centrifuge.
- bituminous materials With the method and apparatus according to the invention it is possible to recycle in a simple manner bituminous materials and to seperate the bitumen or tar from possible aids such as polyester fleece or glass fleece or -fabric and such like, slate chippings and such like and possible other components forming the roofing material, such as adhering or not adhering insulation materials formed by polyurethane, polystyrene, mineral wool and such like.
- the figures 1 to 4 show partly in section a front view of an example of an embodiment of the apparatus according to the invention.
- Figure 5 shows partly in section a front view of another example of an embodiment of the apparatus according to the invention.
- a vessel 1 for bituminous materials bituminous bands or rolls 2 are placed including the slate chippings, the inlaid and any insulation material possibly adhered to these.
- the container 1 is formed by a base plate 3, onto which the bituminous rolls 2 are placed.
- a press or pressure plate 4 is provided which is movable along guiding elements 5 in a direction towards and away from the base plate 3 by means of a drive means 6 not further shown in the drawing *
- the base plate 3 and the press plate 4 can be provided with perforations or openings 17.
- the diameter of the openings may vary. In this example of an embodiment the diameter of the openings is about 1 mm.
- the diameter of the base plate 3 and the press plate 4 is such that these plates 3, 4 fit more or less closely in the vessel 7, while in between the outer circumference 18 of the plates 3, 4 and the inner wall 19 of the vessel a play 20 is present.
- the dimension of this play 20 can vary and it is about 1 mm in this example of an embodiment.
- the container 1 is lowered down into a vessel 7.
- the vessel 7 is filled with a melting medium 8.
- a melting medium liquid hot bitumen 8 or hot fuel oil or another hot melting medium is used of about 200 °C.
- the bitumen 8 is brought into circulation by means of a propeller 21 and is led alongside the bituminous rolls or roof bands 2 which are to be recycled.
- the rolls of waste material will have molten and the other components forming the roofcovering material remain left, such as the inlaids, the cases, the slate chippings, the insulation and such like, and the bitumen from the roof bands will have molten away in the melting medium.
- the press or pressure plate 4 is moved slowly to the base plate 3 as can be seen in figure 3.
- the bituminous rolls 2 are pressed together between the base plate 3 and the press plate 4, whereby the bitumen is pressed out of the remaining materials 2.
- bituminous waste materials such as the rolls in a very simple manner in a melting vessel and to melt these and to remove the bitumen to a large extent and practically completely from the residue by the pressing together, while the removal of the residue and the handling of the residue can also take place in a very- simple manner.
- the plates are exchangeable, so that, depending on on the nature of the materials to be recycled, plates with a smaller respectively larger diameter can be chosen to create a larger respectively smaller play in between the outer circumference of the plates and the inner wall of the vessel, while further plates can be exchanged with smaller or larger perforations.
- the sieve or filter function established by the perforations and the play can be adapted to the dimensions or roughness of the rest materials.
- Figure 5 shows another embodiment of the apparatus according to the invention.
- the container 1 is carried out as a cilinder 12 the wall of which is in the form of a perforated plate 13.
- the cilinder 12 is filled, as can be seen in figure 5, from above with the rolls 2, after which the cilinder 12 is lowered in the vessel 7, as is schematically shown in the drawing.
- the vessel 7 is filled with hot bitumen as described above with respect to figures 1-4.
- the vessel After the melting of the bitumen in the rolls 2 the vessel is pumped empty after which the cilinder 13 is rotated by means of a drive means 6 not further shown in the drawing, and the material is centrifuged.
- the cilinder 13 is supported by support wheels 14 and lateral support wheels 15.
- the bitumen is seperated from the other components by means of centrifugation.
- the residu 16 rests against the wall 13 of the cilinder and can be removed from the vessel in a very simple manner.
- the vessel is heated and that as a melting medium is used liquid hot bitumen 8 or hot fuel oil or another hot melting medium of about 200 °C. Its is however also possible with the method and apparatus to do away with a heating of the content of the vessel and to use instead of a melting medium one or another kind of cold solvent (for instance diesel oil).
- the diameter of the base plate 3 and the press plate 4 is such that these plates 3, 4 fit more or less closely in the vessel 7, whereby in between the outer circumference 18 of the plates 3, 4 and the inner wall 19 of the vessel a play 20 is present.
- the dimension of this play can vary and is about 1 mm in this example of an embodiment. This play is so small that it functions as a sealing between the inner wall of the vessel and the outer circumference of the plates. In an embodiment on a larger scale of the apparatus the problem may come up that this lateral sealing between the plates and the wall poses a problem due to the circumstance that the wall runs out of line or is corrugated.
