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 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 piston stroke of the second cylinder is relatively large. This stroke corresponds to a thickness of the solid phase, that is, for an incompressible product, the equivalent of the length of the die, which therefore requires great oil capacity to operate this cylinder.
  • 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 faster rates than the presses used until now.
  • the press shown in FIG. 1 includes 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 supply 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 connecting the interior of said pressing chamber 9 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.
  • the jacket 12 of the pressing chamber 9 is provided on the side of the outlet orifice 11 with an annular flange 12b (Fig. 2) externally forming a continuous contact surface.
  • 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 parallelepiped shape complementary to the evacuation chamber 14 (Figs. 1 and 2).
  • 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
  • angles of the vertical edges of the slide 15 are cut in the form of a square, the faces of which are provided with guide strips 15a intended to cooperate with the slides 17.
  • a clearance is provided between the slide 15 and the slides 17 to allow lateral movement of said slide against the outlet orifice 11 of the pressing chamber 9, as will be seen later.
  • 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 also includes means 20 for applying the slide 15 against the outlet orifice 11 of the pressing chamber 9.
  • These means 20 are constituted by a jack 21, for example hydraulic, arranged in the axis of the pressing chamber 9, the body of which is integral with the frame 1 of the press and the piston 22 of which moves, over a short stroke, along the axis of said pressing chamber 9.
  • 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.
  • the piston 22 of the jack moves and comes into contact with the slider 15, which has the effect of moving said slider 15 laterally so that its face directed towards the outlet orifice 11 comes to be applied on the outer face of the collar 12b (Figs. 2 and 3).
  • the seal at the outlet orifice 11 is a seal of the metal-metal type obtained thanks to the quality of the surfaces in contact and to the plating force exerted by the piston 22 of the jack 21.
  • the liquid phase is expressed from this raw waste and is evacuated by the chute 13 through the calibrated passages 12a formed in the jacket 12 (Fig.3).
  • 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 use, for closing the outlet orifice of the pressing chamber, by means of the slide, a jack whose piston has a short stroke, of the order of 5 mm and whose capacity d The oil is reduced, thereby obtaining a faster response time and increasing the waste treatment rates.
