Definitions

  • the invention relates to a press for processing materials. fragmented, in particular waste or garbage, containing a fraction of materials likely to flow under pressure.
  • this combustible fraction free of moisture and biomass can be stored for an indefinite period without any nuisance, especially in heaps on open air areas, to be used by combustion during periods with very high energy demands.
  • the fermentable fraction freed from non-fermentable materials can, for its part, be treated under conditions optimal by known methods, in particular by biological seeding and fermentation to produce composts, organic fertilizers or gases likely to provide heat energy.
  • the length of the elements of the frame subject to the forces of the thrust to the extrusion pressure is very important, of the order of 5 to 6 meters, which requires to provide elements of structure very strongly dimensioned without being able to guarantee against a tendency to deformation of these elements.
  • the booster piston is a heavy and expensive element. because it must exercise very different functions consisting, on the one hand, in feeding the extrusion chamber, function during which it moves over a long stroke by exerting a slight push, and on the other hand, exerting pressure extrusion in a very short time.
  • a press such as this has been designed as described in European patent application EP-684 117, comprising a barrel rotary in which three uniformly distributed extrusion chambers are provided around the axis of said barrel, and three filling stations respectively raw material, compression of this material, and extraction of the solid fraction compressed, in front of which are successively brought the extrusion chambers by rotation of the barrel.
  • the length of the frame subjected to the efforts of the pushing to the extrusion pressure is advantageously reduced.
  • this reduction is obtained in particular through the realization of a heavy rotary element which in practice turns out to lead to a relatively complex design with a high cost price, and leading at high maintenance and upkeep costs.
  • the present invention aims to overcome the aforementioned drawbacks of current presses and aims to provide a design press simplified with a lighter structure compared to current presses and requiring reduced operating costs.
  • the idea behind the invention was to make a press designed so that the functions, on the one hand, of filling the chamber extraction and, on the other hand, pressurization and extraction of the material fully separated, thus exempting significant effort from the part the longest of the press, i.e. the one devoted to loading.
  • this separation is obtained by providing the press of a shutter adapted to seal the upstream face of the extrusion chamber when the material is pressurized, so that the thrust exerted on this shutter is reflected on an element of the frame immediately juxtaposed audit shutter.
  • the length of the part of the frame intended to compensate for the efforts of pressurization is limited to the axial length occupied by the chamber during extrusion. This design therefore reduces notably the length of the structural elements subjected to significant efforts and the risks of deformation of these elements, and therefore authorizes much lighter presses with production costs and reduced operation.
  • the pressurization is carried out by a pressure piston having to exert significant efforts but traveling only one weak stroke.
  • the end of the piston presser is kept constantly inside the extrusion chamber, so that all problems of wear and shearing of the materials are eliminated extrude inherent in the entry and exit of conventional pistons.
  • the compressed fraction is ejected thanks to the axial displacement of the extrusion chamber along the pressure piston maintained in its deployed position, displacement which can be obtained easily seen the low relative weight of said extrusion chamber.
  • the means for moving the extrusion chamber have the function, in addition to ejection function, to seal this extrusion chamber while maintaining the upstream face of the latter pressed against the shutter when setting pressure.
  • the press includes an annular seal integral with the shutter and diameter combined with that of the upstream face of the chamber extrusion, adapted to be compressed in the sealing position of this last.
  • the supply means which can be of any type known per se (piston, Archimedes screw), have the sole function of supplying the extrusion chamber and does not participate in any way in the following pressurization operations and extraction.
  • This limitation of the functions devolved to the supply means advantageously leads to making it possible to "lighten” the latter because they do not have to create or undergo significant efforts, and thus reduce the length to less than 2 meters elements of the frame subjected to the efforts of pressurizing extrusion.
  • the pressure piston advantageously has a diameter smaller than the internal diameter of the extrusion chamber, the downstream face of said extrusion chamber being closed by a wall integral with the latter, pierced with an orifice of diameter conjugate with that of said pressure piston.
  • the pressure piston advantageously also has a domed end section in the shape of a cap.
  • a convex form of the end of the pressing piston makes it possible to obtain at any time but mainly to approaching the end of the race, i.e. approaching obtaining pressure final, a compression of the residual mass, then little Pascalian, more important in the center than on the outskirts. This arrangement thus facilitates the migration of the last pasty materials, the most linked to the residue, towards the orifices and towards the free space between the piston and the wall of the extrusion chamber.
  • each orifice of the extrusion chamber incorporates a removable jacket, said extrusion chamber being provided with means for holding each of the shirts in its orifice.
  • each orifice of the extrusion chamber has advantageously a counterbore made at the level of the external face of the wall peripheral of said extrusion chamber, while each jacket has a collar shaped to accommodate the counterbore of the corresponding orifice.
  • the means for holding the shirts comprises then an annular skirt of suitable shape to accommodate the extrusion chamber, pierced radial orifices arranged so as to each extend in the radial extension an orifice of said extrusion chamber.
  • annular skirt in addition to its function of blocking shirts allowing their change after removal of said skirt, allows consolidate the enclosure by forming a hoop.
  • Each orifice of this annular skirt has, in addition, advantageously a frustoconical shape of increasing section in the direction of the face external of said annular skirt, so as to reduce the "blunt" wear which is observed in practice.
  • routing means do not have to create or undergo internal chamber pressure they do not have to be adjusted to the supply duct, but can on the contrary, be of dimensions smaller than those of this conduit. Therefore, are thus eliminated, on the one hand, the shearing of the materials at the entry of the conduit feed or extrusion chamber, and secondly, the subjugations of a bore pushed interfaces and fouling of those interfaces.
  • the element of frame consists of a flat wall parallel to the upstream face of the extrusion chamber, adapted to form the bottom wall of a shutter guide slide, and pierced with a hole coaxial with the axis (x).
  • the shutter advantageously comprises a wall of length greater than the diameter of the extrusion chamber, and has a portion of length consisting of a solid surface wall suitable for sealing the face upstream of said extrusion chamber, during this obturation and to pass on the frame member pushing the pressure piston and the extrusion chamber, and a wall of length pierced with an orifice of conjugate dimensions of said upstream face arranged to be positioned coaxially with axis (x), in the open position said shutter.
  • Such a shutter has a shape suitable for driving, during its movement towards its closed position, a quantity of materials to process with a volume smaller than that of the orifice provided in said obturator, because the routing means having already compacted the load of raw materials, the returns in background material will be limited. Any amount of material that remains in the orifice would then be driven in priority in the extrusion chamber during the next sequence.
  • the shutter also advantageously comprises a contour portion posterior, considering the direction of movement of said shutter from its position opening towards its closed position, presenting an oblique profile inclined in direction of the frame element.
  • the guide means longitudinal of the boost piston consist of the bottom wall of the hopper load having a section in the shape of a circular sector of diameter conjugate with that of said booster piston.
  • the maneuvering means of the boost piston include control means adapted to allow to adjust the positioning of the end of said booster piston in the position retracted from the latter.
  • control means adapted to allow to adjust the positioning of the end of said booster piston in the position retracted from the latter.
  • the drive means in rotation of the worm comprises control means adapted to allow to adjust the number of turns made by said worm during each supply operation of the extrusion chamber. This provision has an objective identical to that for adjusting the retracted position of the boost piston.
  • the hopper of loading and the extrusion chamber are carried by two separate frames sealed on a common base and connected by the connecting pipe, said connecting pipe being consisting of two longitudinal sections respectively secured to one and the other frames, and joined by means of a flexible junction.
  • the structures of the two parts of the assembly, feed and extrusion devices, subject to very constraints are separate. Indeed and in particular due to the differences in diameters between the pistons and / or screws and the cylinders, the rigor of their alignment does not require the more compactness of a common structure, necessarily more rigid due to its length, and therefore heavier and more expensive.
  • control unit includes a manual control adapted to generate a withdrawal additional pressure piston, from its retracted position, to extract the end of said pressure piston of the extrusion chamber.
  • This additional withdrawal pressure piston allows, in fact, to extract it from the extrusion chamber in view any disassembly of the latter.
  • control unit is advantageously a controllable unit adapted to allow the progression of the climb to be programmed in pressure, the value of the final pressure, and the duration of maintenance of said pressure final. Indeed, certain results or characteristics of separate materials depend of these parameters.
  • controllable press unit will allow the choice of the pressure rise curve, for example by controlling the flow rate of the pumps of the hydraulic power unit, as well as the choice of the final pressure and the duration of its maintenance.
  • the progressiveness will be more or less rapid, possibly comprising one or more sequences leading to the final extrusion pressure.
  • the pressure progression curve will be experimentally determinable according to the materials to be treated.
  • the final pressure determines the dryness of the solid residue, which can be more or less sought, particularly in the case where the residue after extrusion must be stored and / or used as fuel.
