Definitions
- the invention relates to a recycling plant for used tires comprising a head for projecting a high pressure fluid.
- Such an installation makes it possible to separate the materials constituting a tire in order to recycle or reuse at least some of the materials.
- Such an installation is described in particular in document Dl (US 5,341,996). It includes a means for maintaining and rotating a tire, and a means for projecting fluid jets on the tire to be treated.
- the projection means comprises a plurality of projection heads each comprising an axis of symmetry.
- the projection means also comprises means for orienting the axis of symmetry of the heads perpendicularly to the surface of the tire to be treated and for rotating the heads about their axis of symmetry.
- a plurality of outlet nozzles which direct jets of pressurized fluid in a direction perpendicular to the tire to be treated or at an angle in order to treat the surfaces of the tire to be treated which do not pass directly under the projection heads.
- the invention proposes a recycling facility for used tires comprising at least one head for projecting a fluid at high pressure onto a surface to be treated.
- the projection head comprises a body rotatably mounted about an axis of rotation substantially perpendicular to the surface to be treated, and a plurality of outlet nozzles suitable for directing each a stream of fluid towards the surface to be treated.
- the installation is characterized in that the plurality of outlet nozzles comprises at least two outlet nozzles suitable for orienting the respective fluid jets in at least two directions having different angles with respect to the axis of rotation.
- the angles between the directions of the jets and the axis of rotation of the projection head are different, so that the jets attack the surface to be treated according to different angles of attack and that the paths of the jets intersect several times when the head is rotated and / or when the surface to be treated moves in front of the projection head. This results in faster cutting of the fabrics surrounding the metal carcass of the treated tire. Also, finer residual particles are obtained after cutting, so more easily exploitable or recyclable. Finally, after complete treatment of the tire, the metal carcass is cleaner.
- each jet attacks the surface to be treated on a ring centered on the axis of rotation of the projection head, regardless of the angle of attack of the jet.
- the angles between the directions of the fluid jets and the axis of rotation of the projection head can be chosen such as the impact zones of the jets.
- fluid on the surface to be treated when the projection head is rotated form crowns substantially adjacent or overlapping slightly.
- the outlet nozzles of the plurality of outlet nozzles are located on at least two radii substantially different from the axis of rotation of the projection head.
- the fluid used can be water under high pressure, which has the advantage of being cheap and easily recyclable after cutting tires, compared to other fluids such as oil. Also water loaded with abrasive particles allows to use lower pressures.
- the invention also relates to a used tire recycling method in which a tire is shredded by projecting a fluid at high pressure by a plurality of fluid jets towards a surface to be treated of the tire, the jets being rotatable around an axis of rotation substantially perpendicular to a surface to be treated.
- the method is characterized in that the fluid jets are oriented in at least two directions having different angles with respect to the axis of rotation.
- FIG. 1 is a schematic view of an installation according to the invention
- FIG. 2 is a view from above of a first embodiment of a projection head of the installation of FIG. 1;
- FIGS. 3 and 4 are respectively a view from above and a side view of a second embodiment of a projection head according to the invention,
- FIG. 5 is a diagram showing the impact trajectories of jets of fluid emitted by a projection head according to the invention.
- Figure 6 is a sectional view of a tire showing the paths of the jets.
- a tire recycling installation 1 according to the invention as shown in FIG. 1
- the installation comprises a frame 4 on which the drive means 5 in rotation of a tire 3 allow to grasp and rotate the tire about its axis.
- the installation also comprises means for supporting a projection head for moving and rotating the projection head.
- the support means also make it possible to feed the spray head with fluid under very high pressure, for example between 2000 and 4000 bar.
- the projection head comprises a body of substantially conical shape and having a main axis of symmetry 12.
- the projection head In operation in a tire recycling installation, the projection head is rotated around the tire. axis of symmetry 12.
- the body 11 is closed by a bottom 13 on which are fixed two nozzles 14, 15 of fluid outlet, of substantially cylindrical shape.
- the two nozzles are positioned on the same radius of the bottom 13.
- the axes of symmetry 16, 17 of the nozzles both cut the bottom 13 at a distance R from the main axis 12.
- the axes of symmetry 16, 17 correspond to the direction of the jets of fluid emitted by the outlet nozzles.
- the axis of symmetry 16 of one of the nozzles forms an angle of 15 ° with the axis of symmetry 12 of the body 11
- the axis of symmetry 17 of the other nozzle forms an angle of 20 ° with the axis of symmetry 12 of the body 11.
- the shape of the body of the projection head is indifferent.
- the shape of the outlet nozzles is equally indifferent, the important thing being only the direction of the jets coming out of said outlet nozzles.
- the projection head 20 also comprises a body 21 of substantially conical shape having a principal axis of symmetry.
- each jet on the surface to be treated has a substantially circular shape, if the direction of the jet is substantially perpendicular to the surface to be treated or substantially elliptical if the direction of the jet is not perpendicular to the surface to be treated.
- FIG. 6 shows the trajectories of the two jets in the thickness of the tire.
- a first series of lines inclined in a first direction with respect to the perpendicular to the surface to be treated 30 corresponds to the trajectories of the jets in front of the displacement, while a second series of lines inclined in a second direction opposite to the first direction corresponds to the trajectories of the jets at the back of the displacement. There are multiple crossings ensuring fine cutting of the particles of the tire 3.
- the angles between the directions 27, 28, 29 of the jets and the axis of rotation of the projection head are such that the impact crowns of the jets to be treated are adjacent and overlap slightly. so that together the impacts of all the jets form a crown of great width (the width of the crown is the difference between the outer radius and the inner radius of the crown).
- the area of the surface to be treated impacted simultaneously by the jets produced by the projection head is important. This is shown in Figure 5.
