Definitions

  • the present invention relates to a method and an installation for the treatment of industrial drums containing liquid waste and, in particular, flammable, explosive and / or toxic liquids.
  • GB-A-839.207 patent further proposes, in the case of small metal containers, such as beer or fruit juice boxes, to pierce and compress these boxes in a single operation, to recover the boxes compressed into patties and collect their contents.
  • This process is implemented by means of a device in which the containers to be treated are brought one after the other between a compression piston and a hollow piercing member which is connected to means for discharging the liquid outwards. contained in the container.
  • this object is achieved thanks to an installation of the kind comprising a barrel press in which the barrels to be treated are brought between a compression piston and a hollow piercing member connected to means for discharging the liquids contained in the barrel, which is characterized by a barrel press comprising a sealed press cylinder closed at one end by a compression piston which is movable along the axis of the cylinder in question, and at its other end by a cover which is intended for the axial introduction of the drums to be treated and which is provided with the piercing member specified above.
  • drums are emptied and compressed in a closed cylinder allows them to be treated without risk of fire or explosion, even if they contain flammable or explosive liquids. By the same token, the dangers to which personnel have been exposed have been removed.
  • the piercing member can consist of at least one hollow pin which ends in a point at its end directed towards the inside of the cylinder and which is connected at its other end to a discharge pipe from the contents of barrels.
  • this pin can advantageously slide, parallel to the axis of the cylinder of the device, through an opening in the cover of the latter.
  • the pin or pins specified above are preferably terminated at a bevel on the side of the press cylinder.
  • the piercing member is constituted by a plurality of pins parallel to each other comprising a central pin which extends along the axis of the cylinder and a plurality of peripheral pins which are arranged according to generatrices of a cylinder of revolution, the axis of the latter coinciding with the axis of the cylinder.
  • the body of the press cylinder according to the invention has a substantially square external cross section.
  • the barrel press described above is advantageously associated with a crane for taking up the barrels to form a mobile assembly and, where appropriate, with other suitable handling devices.
  • the invention also relates to a method for implementing the installation which has just been described, this method being characterized in that the barrel to be treated is axially introduced into the cylinder of the device, which is close the cover of this cylinder, move the compression piston specified above so that the barrel to be treated comes to bear under low pressure on the cover, then move the piercing member inward of the cylinder in order to pierce the barrel, then moving the compression piston inward towards the inside of the cylinder in order to compress the barrel, the contents of which flow outwards through the piercing member, the latter erasing during this phase, and that the cover is finally opened in order to extract axially from the cylinder the treated barrel which is reduced to the pancake state.
  • the barrel press according to the invention which is shown in these figures comprises a cylinder 1, for example at square external section, closed at one of its ends by a piston 2 which is movable along the axis XX 'of the cylinder, as indicated by the double arrow F, under the effect of a double-acting cylinder shown partially in 2a.
  • the cylinder 1 is preferably arranged horizontally or almost horizontally.
  • the cylinder 1 is closed by a cover 3 pierced with openings 4 in which hollow drilling pins 5 can slide parallel to the axis XX ′.
  • These pins 5 end at a bevel at their end situated on the side of the cylinder 1 and, at their other end, they are integral with a plate 6 which they pass through to form a free end piece 5 'intended to receive a discharge pipe. not shown.
  • Two double-acting cylinders 7 are mounted between the plate 6 and the cover 3, on both sides of the set of pins 5, and they allow the latter to slide between a rest position shown in solid lines in FIG. 1 and a position for drilling and flow of the liquid which is indicated schematically in broken lines in this same figure 1.
  • the plate 6 is guided in this movement by four columns 8 which pass through it in the vicinity of its four corners and which are mounted on the cover 3. It is further seen in this FIG. 2 that this cover 3 is articulated along one of its edges on an axis 9 integral with the cylinder 1, and that it laterally exceeds the latter, beyond the axis 9, by an extension 10.
  • a double-acting cylinder 11 connects the end of the latter to the lateral surface of the cylinder 1, and its actuation makes it possible to open and close the cover 3, as indicated by the double arrow F1, with all the members which are integral therewith, namely the columns 8, the sliding plate 6 and the pins 5, and therefore to make accessible and, respectively, to close the interior of the cylinder 1.
  • FIG. 3 shows an advantageous distribution of the pins 5 which are here six in number.
  • One of them, 5a extends along the axis XX ', four others, 5b, are located at the vertices of a square centered on the pin 5a, and the last, 5c, is on the circle which passes through the four pins 5b, equidistant from two of the latter.
  • This last pin 5c increases the flow capacity at the bottom of the cylinder 1.
  • the operating mode of this device is as follows:
  • the cover 3 is opened and the pins 5 are put in the rest position, by means of the jacks 7.
  • Each barrel to be treated is brought in, by handling devices not shown, which may include a crane secured to the barrel press and a chute for introduction of the barrels one after the other, into the cylinder 1 at the rate of only one at a time. We then close cover 3.
  • the piston 2 is pushed by the jack 5a until the barrel comes to bear under low pressure on the cover 3. Then the pins 5 are pushed inside the cylinder 1 by means of the jacks 7. Their bevelled ends pierce the barrel and enter it. The pressure exerted on the pins by the jacks 7 is then removed. It is then that the jack 2a pushes the piston 2 towards the inside of the cylinder 1, which compresses the barrel and, at the same time, drives its contents towards the outside through the axial bore of the pins 5 and the pipes which are mounted on the end pieces 5a of the latter and which discharge it into a suitable pit. During this phase, the pins move back to their rest position as the piston 2 advances. At the end of this operation, the barrels are reduced to the state of pancakes, due to the compression exerted by the jack 2a on the piston 2. After opening the cover 3, they are extracted from the cylinder 1, and they can be recovered in the steel industry.
  • the apparatus which has just been described is advantageously of the explosion-proof type, and that its equipment is hydraulically driven, for example under a maximum pressure of 230 bars, this pressure being approximately 180 bars in the usual regime.
  • the control members of the assembly are conventional and well known to specialists in the field, so that they will not be described here.
