Definitions

  • the present invention relates to a method and a device for the storage of contaminated flexible materials. More specifically, it relates to a method and a device for increasing the quantity of products stored in a given volume.
  • This procedure has the disadvantage that the discarded objects cannot be packed in the drums because of their flexibility or elasticity, and therefore it is a relatively small mass of waste that can be stored in a given volume.
  • the object of the present invention is precisely to improve the efficiency of this operation by making it possible to store a large number of waste in a barrel of given volume.
  • the barrel has grooves and the locking of the edges of the precover takes place in these grooves.
  • a cardboard disc is used as a precover on the edges of which radial slots have been provided.
  • the invention also relates to a device for implementing this method.
  • this device comprises on the one hand means for positioning the barrel and on the other hand means for applying pressure to the precover.
  • the means for positioning the barrel comprise a vertical upright on which is mounted a semi-circular arch, the diameter of which corresponds to that of the barrel.
  • said amount and said support are combined or the support is fixed to the amount.
  • Figure 1 shows the device object of the invention which consists essentially of a vertical upright 2 on which is fixed a half-hoop 4 whose diameter corresponds to the diameter of the barrel 6, shown in phantom, in which one wishes to pack waste.
  • This is a metal barrel of a type commonly used in trade and which has, regularly distributed along its axis, grooves such as 8 projecting outside.
  • a vertical support 10 fixed to the upper part of the upright 2, the support 10 being integral with a horizontal arm 12 whose end opposite to the arm 10 comprises a guide tube 14 in which can slide vertically a rod 15.
  • the latter can be fixed in the guide tube 14 by means of a fixing means, for example a screw 16.
  • a cover 18, identical to those used on drums, has been pierced in its center in order to be able be threaded on the rod 15 and it is retained by a compression disc 17 screwed to the lower part of this last, as shown in Figure 2.
  • FIG. 1 also shows the cardboard precover 20 which is used for each compacting cycle of the waste in the barrel 6.
  • the diameter of the precover 20 is slightly greater than the inside diameter of the barrel 6, but radial slots such as 22 have been provided on its edges so that it can be inserted into the barrel 6 thanks to the deformation of its edges: in fact, the parts 21 comprised between two radial slots 22 are raised during the descent.
  • the rod 15 ends at its upper part by a stirrup 24 into which can be introduced a lever 26 shown schematically in phantom in the figure. Notches 28 formed in the vertical support 10 serve as support points for the lever 26.
  • FIG. 2 The progress of a compaction cycle of the waste is illustrated in the sectional view of FIG. 2.
  • the barrel 6 placed inside the half-hoop 4 secured to the upright 2.
  • the screw 16a been loosened so that the rod 15 can slide in the guide tube 14.
  • the cardboard precover 20 is placed at the top of the waste mass 7 and it is pushed in via the compression disc 17 and the rod 15 on which one acts by means of the lever 26. Au during this movement, the waste settles and the descent of the precover 20 is made possible by the deformation of its edges, the different sectors 21 of which have risen.
  • FIG. 3a we see the barrel 6 placed in the half-hoop 4 and completely filled with a mass of waste 7 not packed.
  • the precover 20 is then installed in which radial slots 22 have been made, then the lever 26 is put in place as shown in FIG. 3b.
  • the lever is placed in the notch 28a located at the bottom of the support 10 and is in the position 26a shown in solid lines on the face.
  • the last cycle in which the waste is placed at the top of the barrel 6, it is in the notch 28b that the end is placed.
  • Figure 3c shows the interior of the barrel after the first compaction cycle.
  • the precover 20 which is immobilized because its edges, equipped with radial slots 22, are blocked in the groove 8a which is the first groove from the bottom of the barrel.
  • the method and the device according to the invention have numerous advantages, the first of which is an increase in the yield of the barrel filling operations thanks to a filling rate three to four times higher than the usual filling rates.
  • the number of drums used is reduced, as well as the transport costs, since a single container is sufficient where three or four were needed with the methods of the prior art.
  • the contamination is limited because the waste thus stored is not very active and the cardboard precover is sufficient to limit the contamination by the temporary closure that it provides between two compaction cycles.
  • the operator does not directly handle the contaminated products and finally, the device is of a very simple construction, therefore inexpensive, and can possibly be modified for the simultaneous filling of several drums.
  • the lever 26 can optionally be replaced by an electrical, hydraulic or pneumatic device, allowing the displacement of the rod 15 under the same conditions as those which have been described previously.
  • Another improvement of the invention may consist in using a device for recovering contaminated air trapped in the volume between the cover 18 and the precover 20 during the compression operation, to be sent to an outlet filter of protection.
