Definitions

  • the present invention relates to a waste shredder, and in particular for reject products from the wood, paper, cardboard, glass and plastics industries. These wastes or lost products are currently not used but simply dumped in landfills where they have the disadvantage of occupying a large volume. However, this waste could, after grinding, be usefully reused, for example when it comes to glass parts, or be used for the supply of poly-fuel boilers, when it is wood waste. This waste is currently not processed due to the complexity and the high cost of grinding and crushing devices on the market, which are only suitable for very precise operations.
  • a first known device is of the planetary grinder type, consisting of two discs arranged at the same height, the shafts of which are inclined so as to form a V open upwards, the two discs carrying cutting tools on their facing faces l 'from each other and being driven at different rotational speeds.
  • the products to be ground are brought into the upper part of the discs and are ground in contact with the tools of the latter before being evacuated to their lower part.
  • Another type of device consists of a grinder comprising a vertical shaft on which knives are fixed, the assembly being mounted in a cylindrical grid, open upwards, the diameter of the mesh of which calibrates the ground products.
  • British patent 1,206,313 describes a grinding apparatus comprising two drums with parallel axes on which are fixed tools arranged in circular helices, these drums being driven manually in opposite directions to each other, movement during which the products are crushed by passing between the two drums.
  • this device has the drawback of being complex in its implementation because the tools are fixed directly to the drums and of being very inefficient due to the manual drive of the drums.
  • the present invention aims to remedy these drawbacks by providing an apparatus for grinding products of different shapes and sizes, or irregular in order to bring them in the form of particles as regular as possible, with an output flow. which is more or less constant, without risk of blocking of the products, even if the feeding is irregular.
  • the apparatus which it relates to, of the type comprising two parallel shafts driven in rotation in opposite directions from top to bottom and from the outside to the inside, each shaft having a plurality of edges regularly distributed over its periphery, each of which is arranged on a circular helix, the pitches of the helices according to which the edges of the two shafts are formed being opposite to each other, and the spacing between the two shafts being such that their respective edges do not are not in contact during the rotational movement, is equipped with a third shaft which, with an axis parallel to those of the first two and arranged below them, comprises tools projecting from its periphery and is driven in rotation.
  • edges according to circular helices ensures the formation of zones for taking care of the products to be ground, of variable width, making it possible to take care of and to pass between the two trees products of different sizes and shapes.
  • edges which are cutting and whose profile is adapted to the nature of the products to be ground ensure the grinding or defibering of the products admitted to their upper part.
  • the third tree arranged below the first two perfect the treatment of the products by ensuring the cutting and grinding of elongated products such as branches of wood, which could simply have been defibrated by passing between the first two trees, without having been cut into small pieces.
  • the rotational speeds of the first two shafts are slightly different from each other, these speeds varying from 25 to 50%.
  • This differential product drive promotes product crushing.
  • This crusher accepts the passage of products of different natures, wood, paper, cardboard, glass, plastic, and for example wooden crates or pallets, without requiring prior disassembly thereof.
  • Adjusting the center distance of the shafts makes it possible to increase the grinding capacity of products of different sizes.
  • edges do not come into contact allows the passage without blocking of hard elements, which may contain the parts to be ground, such as nails, bolts, screws, reinforcement brackets etc ..., when it comes packaging elements.
  • the speed of rotation of the third shaft is significantly higher than that of the first two shafts, the speeds of the first two shafts and of the third varying in a ratio of the order of 1 to 10.
  • the size of the particles is a function of the number of tools arranged at the periphery of the third shaft, and of the speed of rotation thereof. It should be noted that the arrangement of the tools on the third shaft is arbitrary, two tools offset axially which may or may not be contiguous and offset angularly or not.
  • the third shaft is offset laterally relative to the longitudinal median plane of the first two trees, on the side of the tree in the direction in which it rotates.
  • the tools are part of circular crowns engaged on each shaft and locked in rotation thereon, with an angular offset of two neighboring crowns in the case of the first two shafts, so that the corresponding tools, different crowns , are arranged in circular propellers.
  • the crowns carrying the tools can be mounted contiguous or with the interposition of spacers. If the spacers are circular, and set back from the tools, there may be provided a scraper secured to the frame, bearing on each spacer below the plane containing the axes of the first two shafts, and on the outside of each of these two trees.
  • the tools of the first two shafts can either occupy opposing positions, or be offset axially, so that the crowns carrying the tools mounted on a shaft are next to the spacers of the other tree.
  • the latter may have cutting edges, in order to favor the cutting of the crushed materials, which limits the torque necessary for the operation.
  • the apparatus shown in Figures 1 to 4 comprises a frame (2) mounted on feet (3) supporting a housing (4) open both upwards and downwards.
  • This frame serves as a support, with the interposition of bearings (5), to two parallel shafts (6), driven in rotation in opposite directions by means of a gear train (7) from a motor ( 8).
  • a stack of crowns (9) each of which carries tools (10) at its periphery, and circular spacers (12).
  • each crown (9) of a shaft is located opposite a spacer (12) of the other shaft.
  • the crowns (9) are mounted on each shaft (6), so that the edges of the corresponding tools of the same stack of crowns are arranged in a circular helix, the circular helices corresponding to the two shafts being not reverse.
  • a scraper (13) integral with the frame (2) is in contact with each spacer (12) in the lower part thereof.
  • this crusher is also equipped with a shaft (14), with an axis parallel to those of the shafts (6), arranged below these, and driven in rotation by a motor, not shown in the drawing, in the same direction as. the shaft (6) located above it and on the left in FIG. 3. It appears from this same figure that the shaft (14) is offset laterally laterally with respect to the longitudinal median plane of the two shafts (6) of the side of the shaft (6) driven in the same direction as it. As shown in Figure 3, the frame (2) includes lights (15) for adjusting both the vertical and lateral positions of the shaft (14).
  • FIG. 5 represents a variant of the assembly of FIGS. 1 to 4, in which the spacers (18), arranged between two crowns (9) carrying the tools (10), have sharp ends (19), favoring the cutting of the products to be ground, which limits the torque necessary for grinding.
  • each ring (9) has peripheral notches (20) of dovetail or other section, as shown in dotted lines, in which are intended to be fixed tools (10 ) comprising a heel (22) of complementary shape to that of a notch (20).
  • This arrangement is very interesting because it allows, from standard crowns, to mount on them the tools best suited to the grinding to be carried out. In addition, if a tool is damaged, it can be replaced quickly and easily.
  • the products to be ground are brought above the trees (6), where they are supported by the tools (10) that comprise the crowns (9). Due to the variable width opening formed by two corresponding series of teeth corresponding to the two shafts, products of different sizes and / or shapes can be taken care of by said tools, and driven between the two shafts where it is produced, always using tools, grinding the products which come out in the form of small particles at the bottom of the housing (4).
  • the scraper (13), located in the lower part of each spacer (12) prevents an accumulation of crushed products against the spacers, which would be detrimental to the quality of the grinding.
  • the products After passing between the shafts (6), the products come into contact with the shaft (14) rotating at a substantially higher speed; of the order of 50 revolutions per minute if the speed of the shafts (6) is of the order of 5 revolutions per minute.
  • the shaft (14) perfects the grinding of the products and performs the cutting into small pieces of long elements which would not have been ground by passing between the two shafts (6).
  • the invention brings a great improvement to the existing technique by providing a mill of simple design, the size of which can be adapted to the grinding to be carried out, requiring low power, and allowing starting under load.
  • shafts could be of adjustable spacing, could each have a specific drive, or that this mill could have several stages, without departing from the scope of the invention.
