Definitions

  • the invention relates to a crusher or crusher for material made of loose, in a heterogeneous mixture, making it possible to reduce this material to particles of small dimensions in order to reduce the volume as much as possible. His operation uses a system of toothed blades in relative movements linear, simultaneously combining shear functions with crushing functions. If the material in question is essentially organic and not infectious, the ground materials obtained can be used as compost, while in otherwise they can be landfilled directly. Their sort or others treatments such as decontamination or sterilization will be facilitated.
  • the invention solves the problems mentioned above, with know how to obtain a particulate product which can be easily handled and treated later if necessary, transported and stored.
  • the mill according to the invention makes it possible to reduce particles to heterogeneous materials, organic as well as mineral or mixed; he's from small dimensions, silent and consumes little energy, content with a classic electrical connection, as can be found in a simple dwelling. We will also see that it is self-cleaning and that its very design allows very easy maintenance.
  • the orthogonal planes are vertical planes and horizontal.
  • the crusher comprises at least two successive pairs of movable toothed blades making jaws, each couple consisting of two corresponding toothed blades, facing each other, animated by a back and forth movement back and forth to come to a stop against each other when the teeth are engaged with each other, the second pair of blades sliding against the first pair of blades and coming in stop in a position offset from the stop position of the first couple of toothed blades.
  • the blades advantageously have a curved profile, for example S-shaped, to prevent long and thin pieces from protruding the blades without being cut.
  • the blades constituting the pairs of blades are in vertical position and have serrations having horizontal surfaces oriented upward, downward respectively, so that the effects of shear are vertical, respectively horizontal.
  • the blades extend towards the top by upper zones, also toothed, but which do not come engage with each other and instead adopt a positioning geometrical in V when the toothed blades are in abutment against each other others in the crushing area.
  • the shape of the blades and their thickness, as well as the material used, will be chosen according to the products to be ground and the size of the ground ground desired, as will be explained later.
  • the toothed blades constituting the pairs are advantageously arranged obliquely.
  • the pairs of blades can be animated relative to each other by a synchronous or asynchronous movement, and between the moving blades can be inserted between fixed blades or having a different stroke.
  • the blades can approach and move away in a linear stroke located along a coincident axis, in the same plane, or along two planes making between them an obtuse angle different from 180 ° up to 120 ° for example.
  • the convergence movement is then oblique, preferably downwards to further accentuate the phenomenon of self-supply of waste.
  • this back-and-forth movement whatever the or planes, can also be curved or arched, preferably there also oriented the bottom in reconciliation.
  • Such a result is easily obtained by shifting the axis of fixing the blades relative to the point where the back and forth movement properly says is applied to them. This generates a rocking movement, downwards if the point blade fixing is below.
  • Such a crusher can be presented under a modular shape, pairs of toothed blades that can be added to the side of existing blades to increase the grinding capacity, or removed to decrease capacity, weight and size. This is obviously a big advantage compared to traditional shredders, especially compared to screw mills, by nature fixed in their dimensions and capacities.
  • the crusher also includes mechanical parts necessary for its operation, i.e. one or more powered motors electrically or pneumatically or hydraulically, the frames or supports required, the feed hoppers and the outlet and recovery of shredded products.
  • the blades are made of a material sufficiently resistant to cut and crush, while keeping a residual elasticity for take into account the shear forces.
  • the material chosen for the blades or their coating, as well as the shape and design of the teeth and interfaces mechanical depends on the chosen applications. We will mention steel, carbides or nitrides, certain ceramics obtained by sintering in particular, in solid or in plating.
  • stop it does not does not necessarily mean that the teeth come into direct face contact against face; the stop movement may leave a slight space between these two blades, which is precisely of the order of magnitude of the dimensions of the particles of ground materials obtained.
  • the teeth in the abutment area may have a slight cut at the end or chamfer.
  • the mill according to the invention requires at least a couple of blades to work, it is obvious that, in practice, the number of blades will be much higher, typically from a few tens to a few hundred, without this number necessarily being even. Everything will obviously depend on the required grinding capacity and constraints on general dimensions.
  • the width of the blades also depends on the dimensions of the particles of the ground material, as well as the maximum dimensions of the material to be ground, the number of blades placed side by side defining the maximum length of the material accepted.
  • the pair of blades includes a blade 1 or "male” blade, and a blade 2 or “female” blade cooperating with blade 1.
  • Each of these blades comprises holes 3, 4 used to fix them on support shafts and motors not shown, respectively 5, 6 whose purpose is above all to lighten the whole.
  • the male blade 1 comprises an upper zone 7 input which will be used to compact, pre-crush, possibly pre-crush and pre-rip, the material brought into this zone, and a lower zone 8, where crushing and final grinding.
  • the female blade 2 also includes an upper zone 9 and a lower grinding zone 10 whose teeth interpenetrate and cooperate with the teeth of zone 8.
  • the two zones upper 7.9 of the blades together form a V-shaped hopper whose role will be to advance downward the material taken in this hopper.
  • the male blade 1 protrudes, while the part corresponding of the female blade 2 has an S shape, in order to define a passage for the ground material and to prevent pieces from crossing the blades without being treated.
  • teeth are identified by the reference numbers 11.12 on each of the two male 1 and female 2 blades respectively.
  • the blades 11 In their areas upper 7.9, the blades 11 have teeth which have a horizontal face 13 turned upwards. Since the other face 13 ′ of these same teeth 11 is tilted downward, the distance then the approximation of the blades will push the material down, as shown above, creating a self-feeding effect.
  • the teeth In the lower areas of the blades, which are advantageously inclined with respect to the vertical (by an angle ⁇ of approximately 45 ° in the figures, but which can for example be between 0 and 60 °, values which can vary depending on the application), the teeth have a horizontal face oriented downwards 14, respectively a horizontal face oriented towards the higher 15.
  • connection zone comprising teeth 12 more conventional with inclined faces, these faces being complementary so as to be able to come and fit.
  • the upper zones of the two blades form a figure in right V, making feed hopper, with a half opening angle of about 45 ° from the vertical.
  • This angle ⁇ which can be identical or different from the angle ⁇ mentioned above, can also vary between 0 ° and 60 °, and the V can have a curvilinear profile or in successive sections of inclination different.
  • This part therefore forms a funnel for the material to be ground and the form of the teeth present in the funnel goes, as has already been indicated and is clearly visible in Figure 2a, help bring the material down to the lower grinding zone.
  • FIG. 2b which repeats FIG. 2a
  • the grinder according to the invention is equipped with five consecutive pairs of blades (101,201; 102,202; 103; 203, 104,204; 105,205) some of which (201,102, 203, 104, 205) are fixed.
  • the value of 5 mm is only an example, since by varying the above parameters, one can choose the particle size of the ground material.
  • the blade 101 is female and the blade 201 is male, the blade 102 is male and blade 202 is female and so on alternately, the zones 1 and 9, respectively 8 and 10 being correlatively alternately on each on both sides.
  • the mill works as follows.
  • the blades move in approaching and moving away from each other and the material arranged in The hopper is, for large pieces, already torn and pierced. therefore first of all a compacting and partial crushing effect. Thanks to the shape of teeth, the material is pushed down where it compacts more and more.
  • the shearing effect between two consecutive blades sliding one against the other is a vertical shear effect cutting the material, while the shearing effect between two faces of horizontal teeth in the area of grinding is a horizontal shearing effect which also cuts the material.
  • the effect of crushing is obtained by the blades which approach to come to rest one against the other, in the lower zone 8.
  • the parameters of the angles of the funnel and its shape, geometry and length of the lower grinding area are determined to allow pierce, tear or compress the material beforehand in the funnel, push into the grinding area where it will be ground when the teeth come engage each other until the stop, with the clearance imposed by the final size of the ground material.
  • the blades can be mounted on an elastic device (springs or shock absorbers) with play, so that they do not come completely into face to face stop only if there is no ground material caught in them, leaving the necessary clearance otherwise.
  • an elastic device springs or shock absorbers
  • Figure 3 is a top view of the blades in a variant where the grinder alternately comprises fixed blades (102,201,103,204, etc.), shown in gray, while the moving blades (101,202,103,204, etc.) are shown with hatching.
  • the letters a, b, c and d represent different steps of moving away and moving the moving blades together. In a, all blades are separated. In b, the movable blades have exceeded the fixed blades and have therefore removed any material that may have attached to them (cleaning step). In c, the movable blades are just passed over each other and the material has been cut by shearing on the vertical edges. In d, the moving blades penetrate in the fixed blades and the material is sheared horizontally by the faces of the horizontal teeth sliding on each other, then it is crushed and ground into end of stroke. So the moving blades move away and we find our in position at.
  • the grinder is also "self-cleaning", the blades being arranged so that, during their path, the vertical edge of a blade passes against the vertical edge of its neighbors. By moving forward, a blade pushes back the material that can stick on a tooth of its neighbors. The cut pieces will fall lower to undergo a new crushing and shearing action.
  • the blades are actuated by the shafts passing through them (see figure 1). It should be noted here that, depending on the weight of the blades making up the jaws and the material constituting the teeth, the motor movement must be sufficient. However, once the movement has started, the blades being advantageously accelerated over a length of about 30 mm in about a second, the material is cut not only by the force imparted to the blades by the motor movement, but also by the kinetic energy stored. For example, 60 pairs of blades 5 mm thick as shown in Figure 1, actuated by 4 cylinders 25 mm diameter powered by a hydraulic unit with a 0.75 kW motor provide a torque of more than 1 ton.
  • the mill according to the invention can be of dimensions and reduced weight and thus find wide applications in the fields where it is necessary to have a light, energy-efficient grinder to reduce heterogeneous materials, such as waste, in particles as small as possible and decrease the volume.
  • Such a crusher can therefore be used advantageously in small workshops or laboratories or at home, as well as on board aircraft where weight and volumes are the enemies and where we usually only have one generation electric counted.
  • This crusher can moreover constitute one of the elements of a set of grinding in several stages, comprising several (n) grinders according to the invention installed in series.
  • the ground material obtained by a grinder (n-1) feeds the grinder next (n) in the series.
  • hospital waste is in generally a mixture of human tissues, various textile materials (compresses, etc.), rubber materials (surgical gloves, etc.), syringes (mixture plastic and metal), or even paper and cardboard (packaging). Because the fabrics humans are likely to be infectious, hospital waste should not be put in the traditional circuit. On the contrary, they must be treated separately, either in ad hoc centers outside the hospital, or in a treatment center internal to the hospital. They are still huge, noisy and voracious installations in energy, which are associated with sterilization facilities to destroy all pathogenic germs. In all cases, they must be transported out of the operating room.
  • microwave sterilization including a grinder for pre-treatment of waste, small enough that each operating room or each service can have its own device, which avoids any transport and external manipulation.
  • a microwave processing device is described by example in WO 97/44069.
