Definitions

  • the present invention relates to a press for treating heterogeneous waste.
  • waste is constituted by a liquid phase containing only organic products and by a solid phase containing metallic, mineral and synthetic materials.
  • One solution consists in pressing this waste which makes it possible, on the one hand, to obtain residues which are sufficiently dry to constitute a fuel having an acceptable calorific value and, on the other hand, fluid substances which can be used according to their nature, in agriculture as 'soil amendment or as a raw material from which chemicals can be extracted.
  • This pressing chamber comprises an inlet port and an outlet port and has a section equal to that of a piston of a first cylinder.
  • the wall of said chamber has a multitude of perforations opening into a channel for discharging the liquid phase extracted by compression of the waste.
  • the outlet orifice of the pressing chamber is generally closed by a plug carried by a rod of a second cylinder opposite the first.
  • the pistons of the two cylinders are alternately movable between, on the one hand, a first position for compressing the waste and for discharging the liquid phase during which the piston of the first cylinder enters the pressing chamber and the piston of the second cylinder closes the outlet orifice of said chamber and, on the other hand, a second position for evacuating the solid phase during which the piston of the first jack continues its stroke and the piston of the second jack releases the outlet of said pressing chamber.
  • the seal is not maintained at the outlet orifice of the pressing chamber by the piston of the second cylinder, so that leaks from liquid occur and enter the solid phase discharge chamber.
  • the object of the present invention is to avoid these drawbacks and to propose a press which is simple to produce, while making it possible to obtain dry products having a calorific value significantly greater compared to the products obtained using the presses. used so far.
  • the press shown in Figs. 1 and 2 comprises a frame 1 supporting in particular a receptacle 2 forming a supply zone 3 for heterogeneous waste.
  • the feed zone 3 is open upwards and surmounted by a hopper 4 fitted with at least one gland, not shown, making it possible to introduce the waste into said feed zone 3.
  • This supply zone 3 has two opposite lateral openings 5 and 6 of section adapted to that of a compression piston 7 of a jack 8, for example hydraulic, supported by the frame 1.
  • the piston 7 is movable between the opening 5 and a position located beyond the other opening 6 of the feed zone 3.
  • the opening 6 of the feeding zone 3 opens into a pressing chamber 9 coaxial with this feeding zone 3 and of section equal to that of the piston 7.
  • This pressing chamber 9 has an annular shape and has two lateral openings opposite 10 and 11.
  • the pressing chamber 9 internally comprises a jacket 12 pierced with a multitude of small calibrated passages 12a putting the interior of said pressing chamber 9 into communication with means for recovering the liquid phase by means of a chute 13 .
  • the pressing chamber 9 communicates through the outlet orifice 11 with a chamber 14 for discharging the solid phase of the waste.
  • this evacuation chamber 14 is mounted a member movable transversely relative to the axis of the pressing chamber 9.
  • This movable member is constituted by a slide 15 of complementary shape to the evacuation chamber 14.
  • the slide 15 moves under the action of a jack 16, for example hydraulic, between a first position for closing the outlet orifice 11 of the pressing chamber 9 and a second position for opening said orifice 11.
  • a jack 16 for example hydraulic
  • the slide 15 comprises at the lower part of its faces in contact with the walls of the evacuation chamber 14, knives 18 allowing the walls of said chamber to be cleaned during the movement of said slide.
  • the press comprises means 20 for separating the leaks of liquid phase flowing through the outlet orifice 11 of said chamber and of the solid phase.
  • These means 20 consist of a box 21, the bottom of which is provided with an orifice 22 and one of the side walls of which has an opening 23.
  • a pivoting flap 24 between a first position communicating the discharge chamber 14 and means, not shown, for recovering liquid phase leaks via the orifice 22 and a second position connecting the evacuation chamber 14 and means, not shown, for recovering the solid phase via the opening 23.
  • the heterogeneous waste to be treated is introduced into the hopper 4 and pushed into the feed zone 3 for example by a gland not shown.
  • the piston 7 is in the released position as shown in FIGS. 1 and 2.
  • the slide 15 is, under the action of the jack 16, placed in the low position and closes the outlet orifice 11 of the pressing chamber 9 and the flap 24 pivots so as to close the opening 23 and to release the orifice 22 (Fig. 3).
  • the slide 15 is raised under the action of the jack 16 in order to release the outlet orifice 11 from the pressing chamber 9 and the flap 24 switches so as to close the orifice 22 and to release the opening 23 of the box 21.
  • the slide 15 in its downward movement serves as shears in the event of jamming of the solid parts and ensures the cleaning of the walls of the evacuation chamber 14.
  • the piston 7 When the solid parts have been removed, the piston 7 returns to its initial position for a new operating cycle similar to the previous one.
  • This system has the advantage of being able to overcome the sealing constraints at the level of the obturation of the outlet orifice of the pressing chamber and this thanks to a routing of the dry products outside the zone for recovering liquid phase leaks.
  • this system also has the advantage of avoiding any element to achieve a back pressure when pressing the waste.
