Definitions

  • the present invention relates to a removable crusher. It applies in particular to the grinding of contaminated objects, for example chemical or radioactive containers of glass or plastic in a closed enclosure.
  • the various mills known to date are generally of the hammer type and with manual operation.
  • the handling is painful and long for the users and the objects are not shredded efficiently with regard to their volume of storage in barrels.
  • they are difficult to disassemble and manipulate, especially with regard to the replacement of the grinding tool.
  • the invention relates to a removable shredder for small rigid glass or plastic objects, efficient, reliable and robust, allowing easy disassembly and remote handling of its constituent elements.
  • it comprises a substantially cylindrical body, the side wall of which is provided with an inlet for the objects to be shredded and the lower end of which is provided with an outlet for debris from the shredded objects, and a grinding tool disposed between the inlet and the outlet and subject to an axis, the grinding tool having teeth capable of grinding said objects and then entraining the debris of ob crushed jets towards said outlet orifice and the axis being driven in rotation by drive means.
  • said axis is mounted in a drawer housed in a removable manner in the body.
  • said lateral sliding drawer is housed in said body by means of slides formed therein and a removable bar maintains the drawer in the operating position.
  • the axis is slightly inclined relative to the vertical
  • the grinding tool is constituted by a stack of cutters having discs angularly offset progressively along said axis and describing a downward spiral with respect to the cutting direction of said grinding tool.
  • FIG. 1 An example of implementation of the crusher according to the invention is shown in FIG. 1.
  • the crusher firstly comprises a body 2, the main part of which is substantially cylindrical.
  • This body 2 is fixed to a frame 4 by lugs 6 by means of screws 8.
  • An inlet 10 is provided on the side wall of said body. This protrudes from said inlet 10 so as to form a bottleneck 12 channeling objects to be ground towards said orifice.
  • a receptacle 14 is fixed on the neck 12 to receive said objects.
  • An outlet orifice 15 is formed in a lower face of the body 2. It allows the evacuation of the crushed objects.
  • An opening 16 (FIG. 2) is made in the side wall of the body 2. It allows the introduction and the exit of a drawer 18 in the body 2.
  • This drawer 18 slides on slides 20 formed in said body 2 of such so that, when the drawer 18 is fully inserted into the body 2 and in abutment therein, this drawer 18 is positioned fixedly ( Figures 1 and 2).
  • a straight boss 22 is formed on the slide 18 on the face of the latter which first penetrates into the body 2, said boss 22 being able to collaborate with a straight groove 24 formed in the opposite body 2 of the opening 16.
  • a removable bar 26 is rotatably attached to the body 2 on one side of the opening 16 by a screw 27. On the other side of the latter, the bar 26 is capable of engage under a tab 28 allowing it to be held opposite the opening 16 and thus blocking the drawer 18 in the body 2. It suffices to rotate the bar by an angle sufficient to disengage the opening 16 and release the drawer.
  • a passage 30 is formed in the drawer 18 so as to come in the extension of the inlet orifice 10 and the neck 12, the outlet orifice 15 then being disposed opposite the inlet orifice 10 and below said passage 30.
  • a grinding tool 32 is disposed in this passage 30. It comprises a stack of cutter discs 34 secured to a common axis 36. This axis 36 is rotatably supported along a geometric axis slightly inclined relative to the vertical ( Figure 1) by two bearings 38, 40 housed in the drawer 18. A pinion 42 is fixed on the upper end of said axis 36. A double comb 61 bolted by screws 62 to the drawer 18 has teeth 63 which occupy, as can be seen in FIG. 3, the space between each milling cutter 34, which leads to more efficient grinding. Conveniently, the disc cutters 34 have teeth offset angularly and gradually along said axis 36 so as to describe a downward spiral with respect to the cutting direction of the grinding tool. This arrangement allows the objects to be ground to be dragged downwards.
  • a motor 44 for example pneumatic, is fixed on an upper face of the body 2.
  • This motor has at the end of the shaft a pinion 46 able to pass through a hole made in said upper face of the body 2 and to mesh with the pinion 42 When the motor 44 is in place, it rotates the grinding tool 32.
  • the crusher according to the invention is arranged for example in a closed enclosure 48 whose frame 4 constitutes the floor.
  • This enclosure 48 has an opening 50 facing the receptacle 14, allowing the introduction of the objects to be ground into the crusher; an opening 52 facing the outlet 15 allowing the evacuation of the crushed objects; and an airlock 54 allowing the introduction and the exit of elements of the mill to be replaced.
  • a manipulator arm 56 is for example disposed in the enclosure 48 ( Figure 2).
  • One of the objects of the invention is to provide a crusher whose constituent elements are easily removable and remote manipulable.
  • the motor 44, receptacle 14, drawer 18 and grinding tool 32 are easily manipulated.
  • the arm 56 after having turned the bar 26 (in dashed lines), withdraws the drawer 18 from the body 2 and can thus bring it out of the enclosure 48 by the airlock 54.
  • the same operation, performed in reverse, allows the drawer 18 to be replaced with a re-sharpened grinding tool.
  • the arm 56 can dismantle the motor, in the event of a breakdown for example, and replace it.
  • Another object of the invention is to provide an efficient grinder.
  • the inclined axis 36 and the offset of the teeth of the disc cutters 34 cooperate and allow efficient grinding of the objects without plug phenomenon, as well as rapid evacuation.
  • the shape of the drawer can be adapted to needs: one or more tools, one or more drive motors.
