Definitions

  • the present invention relates to a compacting press and treatment of heterogeneous waste.
  • waste is constituted by a liquid phase containing only organic products and by a solid phase containing metallic, mineral and synthetic materials.
  • This pressing chamber includes an inlet port, 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 a large oil capacity to actuate this cylinder. Given this stroke, the response time of this second cylinder is relatively long, which does not allow rapid rates to be obtained.
  • 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 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 supply zone 3.
  • the opening 6 of the supply zone 3 opens into a pressing chamber 9 coaxial with this supply zone 3 and of section equal to that of the piston 7.
  • This pressing chamber 9 has an annular shape and has two opposite lateral openings 10 and 11.
  • the pressing chamber 9 internally comprises a jacket 12 pierced with a multitude of small calibrated passages 12a bringing 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 via the outlet orifice 11 with a discharge chamber 14 of 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
  • the 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 15c (FIG. 2) 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 slider 15 are arranged means for horizontally moving said slider along the axis of the pressing chamber 9 to apply the face 15a of said slider 15 against the annular flange 12b of the orifice 11 of the pressing chamber 9 during compression heterogeneous waste.
  • These horizontal displacement means are constituted for example by four jacks 20 integrated in the slide 15 (Fig. 4).
  • Each jack 20 comprises a piston 21 which can be moved in a direction parallel to the pressing chamber 9.
  • each jack 20 is mounted in a bore 22, one end of which opens onto the face 15b of the slide 15 opposite the face 15a opposite the outlet orifice 11 of the pressing chamber 9 and the other of which end is limited by a bottom 23.
  • the piston 21 has a length less than said bore 22 to form a working chamber 24 and has conventional sealing means 25 at the outer periphery.
  • the piston 21 is traversed by a through bore 26 in which is mounted a pin 27 comprising a first shoulder 28 intended to come to bear on the lateral face 21a of the piston 21.
  • the cylindrical part 29 of this shoulder 28 is slidably mounted in a central bore formed in a flange 30 housed in a recess 31 provided in the bore 22.
  • This flange 30 is held, for example, by screws 32 distributed over a circumference symmetrically.
  • the axis 27 comprises a second shoulder 33 having an annular section concentric with the annular section belonging to the first shoulder 28.
  • the space between the second shoulder 33 and the face of the flange 30, being opposite, is filled by an elastic return member of the piston 21.
  • This elastic return member is composed for example by Belleville washers 34.
  • the flange 30 divides the working chamber 24 into a main chamber 24a and into a secondary chamber 24b, said chambers 24a and 24b communicating with each other by at least one orifice 35 provided in said flange 30.
  • This arrangement allows the working fluid to act on the equivalent of the dynamic section of the piston 21.
  • the sealing of the working chamber 24 to the outside, passing through the bore 26, is ensured, for example, by an O-ring 36 housed in a suitable groove formed on the axis 27.
  • the supply of pressurized fluid to the working chambers 24 of all the jacks 20 is produced by a central duct 37 crossing the entire height of the slide 15 and positioned along the axis of symmetry of the distribution of said jacks 20.
  • This central duct 37 given its diameter and its secant position in the main chambers 24a of the jacks 20, ensures simultaneous distribution of the pressurized fluid in the different chambers.
  • the central duct 37 is connected by a threaded connection 38 screwed on the upper face of the slide 15, to a pipe 39 for supplying pressurized fluid.
  • a drain plug 40 is provided in the lower part of the central duct 37.
  • the Belleville washers 34 are mounted and held without constraint by means of a tightening nut 43 screwed onto the threaded end of the axle 27 located opposite the second shoulder 33.
  • the nut 43 is housed in a counterbore 44 dimensioned so as to completely retract said nut 43 inside the piston 21.
  • the operation of the press described above is as follows:
  • 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 slide 15 is, under the action of the jack 16, placed in the low position opposite the outlet orifice 11 of the pressing chamber 9.
  • the pressurized fluid is admitted through the flexible piping 39 and the central duct 37 into the main chambers 24a and through the orifices 35, into the secondary chambers 24b of all of the cylinders 20.
  • the pistons 21 move in a direction parallel to the axis of the pressing chamber 9 and the faces 21b of these pistons come into contact with the wall of the discharge chamber 14 situated opposite the outlet orifice 11, which causes the Belleville washers 34 to be compressed and, by reaction, the lateral displacement of the slide 15 so that its face 15a directed towards the outlet orifice 11 comes to bear on the external face of the flange 12b and thus closes said outlet 11 (Fig. 2 and 5).
  • the seal at the orifice 11 is a seal of the metal-metal type obtained by virtue of the quality of the surfaces in contact and the plating force exerted by the pistons 21 of the jacks 20.
  • 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. 5).
  • 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.
  • a variant of the horizontal displacement means of the slide 15 has been shown along the axis of the pressing chamber 9 for applying the face 15a of said slide against the annular flange 12b of the orifice 11 of the pressing chamber 9 during the compression of heterogeneous waste.
  • These horizontal displacement means of the slide 15 are constituted by a flat piston 50 sliding in a jacket formed by the slide 15 itself.
  • the flat piston 50 is slidably mounted in a bore 51 formed inside the slide 15, in the axis of the pressing chamber 9.
  • This bore 51 has one end which opens onto the face 15b of the slide 15 and another opposite end which is limited by a bottom 52 into which opens a bore 53 of smaller diameter.
  • the bore 53 also opens onto the face 15a of the slide 15.
  • this bore 53 is mounted, by means of a screw 54, an axis 55 which comprises a portion 55a of larger diameter disposed in the bore 51.
  • the end of the bore 53 emerging at the level of the face 15a of the slide 15, is closed by a plate 56.
  • the piston 50 has an internal bore 57 of larger diameter than the part 55a of the axis 55.
  • a sliding ring 58 On this part 55a of the axis 55 is mounted a sliding ring 58 on which is arranged a hemispherical element 59 which is intended to cooperate with another hemispherical element 60 of complementary shape, fixed in the bore 57 of the piston 50.
  • the two hemispherical elements 59 and 60 therefore form a ball joint.
  • the hemispherical element 60 is held in the bore 57, on one side by a flange 61 and, on the other side, by a spacer 62 on which a spring washer 63 is applied.
  • the spring washer 63 is mounted on a spacer 64 held on the end of the axle 55 by an immobilizing flange 65 and a screw 66.
  • the piston 50 provides with the bottom 52 of the bore 51 a working chamber 67 at which the conduit 37 for supplying pressurized fluid opens.
  • adjustable stops 68 are provided in this room.
  • the contact zone 69 between the piston 50 and the bore 51 is formed by a hemispherical bearing comprising a seal 70.
  • the seal is completed by a scraper seal 71 fixed on the face 15b of the slide 15 and which is applied to the lateral face of the piston 50.
  • This system has the advantage of being able to be used to close the outlet orifice of the pressing chamber by means of the slide, at least one jack being integrated in said slide and having a short stroke, of the order of 5 mm and whose oil capacity is reduced, thus obtaining a faster response time and increasing the waste treatment rates.
