  • the envelopes and packages do not prevent fermentation and provide only inadequate mechanical resistance of the finished block so that it is subject to cracking of the envelope followed by disintegration of the block.
  • the method which forms the subject of the present invention has the aim of removing the above disadvantages. It is characterised in that the refuse, which has been crushed and homogenized is dampened and subjected to a compression of the order of 300 to 500 bars the mass being penetrated by perforated tubes for evacuating the liquids duringcompression.
  • the dry, compressed mass may be stored, ground and caked with a binder so as to form, under reduced compression, blocks of specific size having an increased mechanical resistance or it may be used as a pulverised fuel in an incinerator.
  • the binder is preferably constituted by sodium silicate hardened with C0,.
  • the hardening with CO may be obtained by the injection of gas or better by adding cement to the binder giving off CO, as it solidifies.
  • the sludges are subjected to a fermentation in a narrow bed with constant stirring for a period of about 4 to 5 hours in an enclosure at 60-70 C, said enclosure being traversed by an air current.
  • This fermentation produces dry granules which are not subject to putrefaction or fermentation and which may be used as compost or dissolved in water to form a liquid fertilizer.
  • the effluent gas is a mixture, which after washing to remove the water may be used as a fuel or as air charged with combustible gas to incinerate the solid deposits or for supplying the hot air generator of the fermentation installation.
  • the dry substances contain a high percentage of cellulose fibres. Accordingly and in conformity with another feature these dry substances'are dispersed in a water bath containing 10-20 percent by weight of soda and, after maceration, the solids are separated and subjected to compression with the material in the course of compression traversed by perforated tubes for evacuating liquids.
  • the liquid part which is evacuated is a suspension of cellulose fibres which after concentration produces a paper paste.
  • the dry part which is obtained after compression may be mixed with a binder and moulded to form blocks.
  • the installation for practicing the method comprises a storage cavity, a device for mixing and homogenizing the refuse, an immersion tank, a crushing device and a press having perforated tubes for evacuating the liquids passing through the compression chamber.
  • the installation comprises a double press with a conveyor bringing the refuse which has first been mixed and homogenized to a double grinder, which then distributes the refuse to two load feeders, the fixed casing of the grinder having helically disposed blades, forming the'immersion tank for dampening the refuse, the load feeders being positioned above the two compression chambers disposed on either side of a central jack, the upper part of eachcompression chamber being closed by a swinging door cramming the refuse into the said chamber, the base of the chamber having apertures for the passage of the perforated tubes for evacuating the liquids and the lower wall of the chamber having a flap valve for removing the compressed block, the pistons acting in the said chambers each being integral with the opposite rod of the piston of the double acting central jack.
  • FIG. 1 is a comprehensive view in longitudinal crosssection of a compression installation
  • FIG. 2 is a detailed view on a larger scale of the grinder on the right of FIG. 1;
  • FIG. 3 is a detailed view on a larger scale of a load feeder and its compression chamber
  • FIG. 4 is a sectional view along IV-IV of FIG. 3.
  • the installation comprises a conveyor belt 1 which supplies it with refuse held in a storage cavity having been suitably mixed and homogenised.
  • metal parts and very hard materials which are too large, are removed from the refuse.
  • the refuse falls into a crusher formed by two flanged crushers 2 turning in opposite directions.
  • the crushed refuse falling from the crusher 2 is directed by an oscillating paddle 3 towards one or the other of the grinders.
  • These two grinders are constituted (FIG. 2) by two shafts 4 driven by a central hydraulic motor 5 and supported at their free end by a bearing 6 integral with the casing 7 of the machine.
  • Each shaft 4 bears grinder blades 8 helically disposed to make the refuse move forward in the grinder.
  • Each shaft 4 is surrounded by a cylindrical housing 9 bearing fixed grinder fins 10.
  • Metal sheets 11 are fixed at the two ends of this housing 9 and these close off the lower section of the cylindrical housing to form a tank for damping the refuse.
  • the cylindrical housing 9 of the grinder is mounted so as to be mobile in the casing of the machine, according to the axial direction of the grinder this displacement being controlled by a jack 12. This possibility of displacement allows the fixed blades to be moved towards or away from the mobile blades to obtain a finer crushing or to allow foreign bodies, which are likely to block the grinder to pass through.
  • the end wall of this feeder has a swining door 14.
  • This door is formed by a frame 15 rotatably mounted about a shaft 16 and driven by a hydraulic motor 17.
  • the frame comprises a cylindrical segment wall 18 and a closing plate 19 between the edge of the cylindrical segment wall 18 and the shaft 16.
  • the plate 19 In the open position (shown on the left in FIG. 1), the plate 19 seals the outer wall of the feeder 13, sealing at its upper part being ensured by a valve 20 articulated on the inner surface of the lateral wall of the feeder, the base of the feeder being, at this time, connected to the compression chamber, which will be described hereinafter.
  • the closed position In the closed position (shown on the right in FIG. I), the plate 19 has turned so as to seal the base of the feeder, sealing being ensured by a sealing wedge 21 pushed against the corner edge of the plate 19 by the springs 22.
  • the door is locked in position by the engagement of a key-pin 23 driven by a jack 24 into the bore hole of pin fitting 25 provided on the frame 15.
  • the compression chambers 29 are located below the aperture in the base of the feeder. Their upper surface is formed, at least in part, by the plate 19 of the swinging door in the closed position. The part of their lower surface adjacent to the base is also formed by a swinging door comprising a frame 30 rotatably mounted about a shaft 31 and driven by a hydraulic motor 32.
  • the frame 30 is provided with a plate 33 with a chamfered edge which co-operates with the chamfered edge of the lower fixed wall 34 of the compression chamber.
  • This swinging door is locked in a closed position by a key-pin 35 driven by a jack 36 and engaging in a bore hole of a pin fitting 37 integral with the frame 30.
  • each of the chambers 29 a piston 38 is displaced by the rod 39, 40 of a double-acting jack 41.
  • the cylinder of this jack 4] is mounted in the middle between the two compression chambers.
  • the bottom wall of each chamber 29 comprises apertures 42 (four in the embodiment shown in FIGS.3 and 4) which extend by means of sealing sleeves 43 outside the chamber. Bores 44 in the form of perforated tubes are slidably mounted in these sleeves. These bores may be pushed into or extracted from the chamber 29 by the jacks 45.
  • the ends of the bores are connected to tubes 46 which lead to a vacuum chamber (not shown).
  • Conveyor belts 47 are mounted below the swinging doors 30 and these convey the compressed blocks to a central conveyor belt which removes them.
  • the body of the jack 41 is mounted on the frame of the press by means of two pivots 49, which permit the cylinder of the jack to rotate, after the pistons have been disconnected and thus facilitate repairs.
  • the installation operates in the manner described hereinafter, certain operational details already having been described above.
  • the mixed, sorted and homogenised refuse passes into the crusher 2 which destroys the hard bodies such as bottles, bits of stone, etc..
  • the flow of refuse is directed by the paddle 3 towards the grinder in which it is mangled and moistened.
  • the refuse then falls into the feeder 13, the door 14 of which is closed, the plate 19 sealing the compression chamber 29.
  • the piston 33 located below the feeder is drawn back by the jack 41.
  • the door 30 is raised by the hydraulic motor 32 to close the lower wall of the compression chamber and is locked in the closed position by the key-pin 35 driven into the hole of the pin fitting 37 by the jack 36.
  • the hydraulic motor 17 then drives the door 14 in the opposite direction, thus forcing the refuse in the feeder into said chamber.
  • the door 14 is locked in position by the key-pin 25.
  • the bores 44 are plunged by the jacks 45 into the mass of refuse filling the chamber and the channels 46 are put under vacuum.
  • the jack 41 is supplied with power to plunge the piston 38 into the chamber 29.
  • the bores 44 which withdraw in relation to the advance of the piston 38 extract a liquid sludge, the volume of which may be as much as 50 percent of the initial volume of the refuse.
  • the compression reaches 500 bars and a block of dry substances is to be found compressed in the chamber above the swinging door 30.
  • This swinging door is released, the jack 36 ensuring retraction of the key-pin 35.
  • the door is swung by the hydraulic motor 32 to allow the block of dry substances to fall onto the conveyor 47, which transfers it to the conveyor 48, which discharges it.
  • the dry substances obtained constitute a virtually inert product havi ng, loose packed, a density greater than 1.
  • the blocks of dry substances obtained were disintegrated and mixed with according to the quality required for the final block 4 to 20 percent in weight of sodium silicate, modulus 2 and with a 45 percent concentration and a percentage by weight of cement lower than the percentage by weight of the silicate but greater if more rapid setting is required.
  • the mixture was then moulded under a pressure of 20 bars to obtain the blocks in their final form. As the dry matter is practically incapable of being compressed further, the blocks may be formed with accurate and stable dimensions.
  • the cement ensures the giving off of C0,, which permits rapid setting of the sodium silicate.
  • the blocks obtained have, after hardening, a mechanical resistance which varies with the quantity of the binder but which is generally between and 24 kg/cm and a density of about 1.1. It should be noted that if fermentation were to occur in the blocks, CO, would be produced, which would incrase the hardening of the silicate, thus preventing fermentation from developing.
  • the blocks may be covered with a light layer of plastic or enveloped in asphalt.
  • the liquid sludges obtained are made up of substances which are very rapidly consumed by the bacteria they contain. Fermentation is rapid and produces a very rich fertilizer in contrast to the composts in which the bacteria have to destroy the dry substances.
  • the block of dry substances obtained at the outlet of the press was disintegrated and the pulverulent product injected by a current of air into the combustion chamber of an incinerator where it burned like charcoal dust.
  • the 44 kg of dry substances were poured into a tank containing about 200 litres of water with 15 percent soda and, after maceration, they were subjected to compression in the same press as that used for compressing the refuse.
  • the total weight of the bulk subjected to compression was about 53 kg.
  • a dry sediment of about 22 kg was obtained after compression and this was crushed and caked together in the way described above so as to produce blocks containing substantially mineral and plastic substances and metallic elements which were not removed when the raw refuse was sorted.
  • the 31 kg extracted in the form of a suspension were filtered to remove part of the soda solution which was returned to the maceration tank, the filtration cake constituting a paper paste which could be used for the manufacture of cardboard.
  • a method of treating household refuse comprising crushing and homogenizing the refuse, moistening the crushed and homogenized refuse with water, inserting perforated tubes into the moistened ref se and s ubjecting the moistened refuse to a compression of at least about 300 bars, and withdrawing through said tubes liquid sludges expressed from said refuse during said compression leaving dry compressed substances.
