Description

Title of the invention: Device for recycling polyester materials

[0001] The present invention relates to a device for recycling polyester materials.

[0002] Following the explosion in the production of raw materials linked to the energy market in all countries, the recycling of polyester waste is becoming a major issue. A first problem is logistical. Indeed, the recycling of polyester waste is managed by large structures which, due to the volume processed, oblige small structures to store a large quantity of waste, before removing it for recycling. Storage and transport costs remain high. Indeed, small structures are obliged to make several trips to evacuate this bulky waste to their storage sites, generating high transport costs for each site.A second problem is that recycling of this waste remains limited to around a third of the volumes generated, the rest being destined for landfill.

[0003] The proposed device allows the rapid reuse of this polyester waste while retaining its particle size. This reduces the volume of waste generated by the construction site, but also the number of transports to evacuate this residue to the storage point and the volume of waste intended for landfill; these recycled materials can be reused as is as raw material for industry.

[0004] According to a variant, the device will consist of a first mechanical assembly having the function of partially destructuring and ejecting these compound materials towards a second electromechanical assembly equipped with a vacuum device. This second electromechanical assembly has the function of disintegrating the compound materials into granulometric elements which will be evacuated by a vacuum device.

[0005] The first mechanical assembly is composed of a box, a held keyed shaft, an accessorized cylinder, specific sheets and a driven movement means. The box has at the front a first inlet orifice, in its lower part a second outlet orifice and lateral fixings for support bearings of a keyed shaft; a driven motor means is coupled to one end of the keyed shaft. A cylinder is provided with expulsion fingers followed by round destructuring rods. The expulsion fingers are positioned from each other at 45° on the central axis and offset by 45° on the circumference and the length in order to allow a sequential ejection of the compound materials. The rods, of lesser height, initiate the disintegration of the compound materials into granulometric plates.On each side of the first box, two oblong sheets, equipped with flanges, facilitate the assembly and disassembly of the cylinder, the shaft and the bearings; they are held in place by screws. box. A removable plate, held by hinges, with the imprint of the surface of the expulsion fingers, is aligned and held at a defined angle in relation to the axis of the cylinder; a threaded rod with nut allows adjustment and a compression spring ensures the safety of the moving assemblies.

[0006] The second electromechanical assembly is composed of a mechanically welded frame; guided, adjustable plates and turntable supports; a motor means coupled to a first shaft equipped with a first cylinder or "cam"; a second shaft and a third, both mechanically synchronized to the motor means and respectively equipped with a second cylinder or "cam" and motor means driven by the first assembly; and a vacuum device. A groove or pitch is machined in the cylinders in order to convert the uniform circular movement of the motor means into rectilinear and alternating movement. The study of "the speed in the circular movement", "the speed in the translational movement" and "the resulting speed" on the axis of the cylinder formula "AUVW" confirms the data of the helical pitch as close as possible to our needs: the speed and the length of the translational movement.

[0007] The guided plates are held by axes by means of bushings and set in motion by rollers, themselves driven by the grooves or machined steps of the cylinders or "cam". The disintegrated materials are sucked from the first set onto the plates fixed to the guided plates. The rectilinear, alternating translational movement of vector _ jyjjyj = U and °PPosed of the plates and their adjustable geometries finish disintegrating the materials into homogeneous granulometric elements. The device as a whole is connected to earth.

[0008] A ventilation device is adapted to the ball collection container, of regular shape. The air flow causes a varying depression in the container and induced in all the boxes; thus it sucks the particles towards the container and the ejection device. The container and the pipes have a diameter, a radius adapted to the movement of the balls. Then ejected into a recovery device for recycling and reuse.

[0009] The first assembly, called the upper receiving box, is made up of an assembly of mechanically welded sheets supporting a destructuring cylinder equipped with expulsion fingers, and a removable, serrated support plate held by a hinge; a second assembly, called the lower decomposition box, is made up of a mechanically welded tubular frame held by spacers, supporting mobile plates for holding high and low granulometric decomposition plates equipped with pyramid-shaped points of different heights; and a depression and expulsion group.

[0010] The second box, called the lower box, is equipped with a motor assembly consisting of pinions, a chain, bearings, shafts, cams and a motor means; secured to the chassis.

[0011] The destructuring cylinder, equipped with rods intended to destructurize the compound materials and supported by the first upper box, is driven by the motor assembly by means of a cascade of pinions; the toothed plate is stamped according to the imprint of the expulsion fingers and amplifies the function of the cylinder by maintaining the compound materials in contact with the rods fixed to the cylinder.

[0012] The turntables are driven by cams which convert the rotary motion of the driving means into linear and reciprocating motion.

[0013] The depression and expulsion group composed of a collecting tank, a fan, bent tubes, a venturi.
