Definitions

  • the present invention relates to a garbage disposal and, more specifically, a helical-sized garbage disposal.
  • a horizontal shaft carries hammers mounted on a pivot and the crushing or crushing results from the impact of the hammers on thick plates forming anvil.
  • a grid can be mounted under the rotor to refuse excessively coarse fragments.
  • Blade crushers which are especially suitable for tough or fibrous materials, exert several successive shears which prove to be more effective than impacts. Normally, they comprise a rotor provided with knives uniformly spaced at its periphery which exert a shearing effect with fixed knives carried by the crusher housing.
  • Heterogeneity is, however, a specific characteristic of refuse which is formed by waste of all kinds and of all dimensions, for example plant and animal waste, glass, plastics and rubber possibly reinforced with fibers or yarns. steel, etc. Reducing the size of the refuse can therefore not be done rationally with hammer or blade crushers. It is well known that the production capacity and the fineness of cutting or grinding are of paramount importance for the profitability of the process chosen for the destruction and composting of refuse.
  • the invention relates to a helical cutter having, as main advantages, the fineness of cut, regularity of operation and ease of maintenance.
  • the shredder according to the invention is a shredder shredder with low rotational speed which is capable of reducing even very large or very stubborn objects into centimeter particles, such as household appliances and tires.
  • the fineness of grinding achieved by means of the crusher described above with not very brittle materials depends not only on the particular dimensions of the different organs of the crusher, but also on the overlap between the serrated rings on each stage. Grinding is obviously all the more fine as this overlap is more important, that is to say that the trees are closer to each stage of the mill. Consequently, so that it is possible to adjust the fineness of grinding and also to correct the parallelism between the shafts during assembly, the bearings of the four shafts of the mill can each be moved apart or brought closer to the homologous bearing of the other shaft. on the same floor by means of jack screws housed in the thickness of the end walls of the frame. The force exerted by the screws on the bearings is distributed by furs.
  • the bearings of at least one of the shafts on each stage are fitted with hydraulic cylinders which allow the momentary lateral spacing of their shaft and then return it to its set position when a body too hard , for example a bicycle hub; is brought to the crusher.
  • the crusher is actuated by a geared motor group.
  • Fig. 1 is a schematic side view in elevation of the crusher 1 forming the subject of the invention equipped with its geared motor group (not numbered).
  • the gearmotor group mounted on a raft 2 carrying in turn a base 3, comprises, for the lower secondary grinding stage 4 of the crusher 1, an electric motor 5 fixed on the raft 2 and driving by a brake coupling 6 a reduction gear 7, for example with three trains of cylindrical gears with helical teeth, fixed on the raft 2.
  • the gearmotor group comprises, for the upper stage 8 of the mill 1, an electric motor 9 fixed on the base 3, a coupling with brake 10 and a reducer 11 fixed on the base 3.
  • the attachments to the base and the base are made by means of plates with anchor bolts embedded in the concrete.
  • This pinion cage which will not be described in more detail, transmits the movement to stages 4 and 8 of the crusher 1 by ball-joint extensions 15 in equal number to that of the grinder's shafts. Only two ball joint extensions 15 are shown in FIG. 1. These ball joint extensions allow the normal rotation of the trees despite the variability allowed between their respective centers in the horizontal plane. These conventional ball joints are not described in more detail and are normally housed in a cage (not shown).
  • Fig. 2 illustrates by a schematic and partial perspective view the arrangement of the main organs of the crusher 1.
  • the upper stage 8 or upper primary grinding stage is constituted by a chassis 16 in the form of a rectangular parallelepiped open at its upper face and at its underside and delimited by side walls, of which only the left side wall 17 is shown, and by end walls, of which only the rear end wall 18 is shown.
  • Two fluted counter-rotating shafts 19 and 20 whose directions of rotation are indicated by arrows, which are substantially parallel and horizontal, are carried by bearings (indicated in Fig. 5) which are themselves arranged in the end walls. .
  • Each shaft carries a series of identical serrated crowns 21 which are offset regularly each with respect to the previous one on the same shaft, following a propeller having its pitch in the direction of rotation of the shaft to which it belongs.
  • the succession of crowns constituting the two helices in stage 8 is indicated by the dotted line passing through the homologous teeth 22 of pairs of extreme crowns.
  • the crowns 21 each comprise a hub 23 which comes in one piece with the crown, projecting from a face thereof and having a length at least equal to the maximum thickness of the teeth of its crown, as illustrated in detail in FIGS. 7 and 8.
  • the crowns 21 carried by the same shaft all have their hubs in the same direction and those carried by the other shaft of the same stage have their hubs in the other direction, so that the shafts can be brought together sufficiently so that there is overlap between the crowns 21 of the shaft 19 and the crowns 21 of the shaft 20, because the teeth pass each time in front of the hub of the opposite crown.
  • the chassis 16 is also provided with a trough-shaped feed and non-return device comprising two combs, of which only the comb 24 on the left is shown.
  • Each comb 24 is formed of a stack of plates 25 and 26 carried by the side walls of the frames.
  • the plates 25 constitute the teeth of the comb 24, while the hollows thereof consist of the plates 26.
  • the teeth formed by the plates 25 are inserted without friction between the crowns 21 of the nearest shaft and in outside the path of the crown teeth of the other shaft, so that the crown teeth grip the material feeding the stage.
  • the lower stage 4 or lower secondary grinding stage has a constitution similar to that of the upper primary grinding stage 8, but in this case the counter-rotating shafts 27 and 28 carry serrated rings 29 which are twice as thin as the serrated crowns 21.
  • the number of thin serrated crowns 29 is twice that of the serrated crowns 21. Consequently, the helical pitch defined by the thin serrated crowns 29 is twice as tight as the helical pitch defined by the serrated crowns 21.
  • the lower floor also includes two combs that are twice as tight as the combs on the upper floor.
  • the chassis 16 of the upper stage 8 and the chassis (not numbered) of the lower stage 4 are made of welded rolled steel and are assembled by positioning pins and bolts.
  • Fig. 3 is a plan view of the crusher, on which the chassis 16 is clearly visible, as are the shafts 19 and 20 of the upper primary grinding stage. Between the teeth of the combs, the serrated rings 21 are positioned on the shafts 19 and 20 so as to constitute the two opposite pitch helices. The plates 25 and 26, visible from above, are fixed to the side walls 17.
  • Fig. 4 is a sectional view along the line IV-IV of FIG. 3.
  • Fig. 4 clearly shows that the upper stage 8 and the lower stage 4 are carried together by a base 31 in the form of a rectangular parallelepiped open at its upper face and at its lower face and delimited by side walls 32 and end walls 37, 38 (Fig. 5).
  • This base also made of welded rolled steel is secured to the chassis of the upper stage 8 and the lower stage 4 as well by positioning pins and bolts.
  • the side walls 32 of the base 31 and the bottom plate 33 support, instead of combs, lateral oblique sheets 34 which, with oblique end sheets 39 shown in FIG. 5, constitute an outlet hopper, the lower passage of which is indicated at 35.
  • the place occupied in the end walls of the chassis by the bearings of the shafts is indicated by dotted lines on the different stages in FIG. 4. These bearings are shown in more detail in Fig. 5.
  • the different plates 25 and 26 constituting the combs 24 join the side walls of the frames of the two stages and are fixed to them in a manner not indicated in detail.
  • the jack screws 36 which allow the parallelism of the shafts to be adjusted by moving the bearings in the end walls, are indicated for the four shafts of the two stages.
  • Fig. 5 is a sectional view along the line V-V of FIG. 4 and shows the splined shaft 19 of the upper stage and the homologous shaft 27 of the lower stage.
  • the helical arrangement of the leading edge of the crown teeth also appears in this figure, which also shows that the crowns of the lower stage 4 are twice as thin and twice as numerous as those of the upper stage 8
  • the front 37 and rear 38 end walls of the base mounted on the plate 33 carry the oblique end plates 39 which, with the lateral oblique plates 34, constitute the outlet hopper around the passage 35 formed in the plate 33.
  • the rear bearings 41 and the front bearings 40 are designed for adjusting the parallelism of the shafts and the fineness of grinding. These various bearings are mounted in the end walls of the mill so that they can be brought to the required position by screws forming a jack 36.
  • Fig. 6 which is a sectional view along line VI-VI of FIG. 5, shows how the anterior bearings ⁇ -0 of the same stage are positioned relative to one another by means of the screws forming a jack 36, the pressure of which is distributed by flanges 42.
  • one bearing is movable elastically relative to the other by the intervention of two hydraulic cylinders 43 which are Ali mented by a common pipe 44.
  • These hydraulic cylinders 43 whose piston 45 has a diameter of 55 mm are of conventional type and are not shown in more detail.
  • These jacks also appear in section in FIG. 5.
  • Fig. 7 is a view of a serrated crown 21.
  • the crown comprises five teeth 22 of arcuate shape, the cutting or leading face of which is at an angle of about fifteen degrees relative to the radius passing through the top of the tooth .
  • Each tooth 22 carries a coating of Stellite 46 applied to the torch. This coating covers the entire hollow 47 of the tooth 21 as well as a small region 48 on the back of the tooth. From the part of the toothed crown which forms the hub 23, the teeth are profiled with their lateral faces 48 (see FIG. 8) slightly oblique to avoid any risk of jamming.
  • the hub 23 which is an integral part of the crown, protrudes only on one of the two faces of the latter and gives the complete serrated crown a thickness at least equal to the sum of the maximum thicknesses of the teeth of two crowns carried by trees on the same floor.
  • the hub 23 is pierced with a bore 50.
  • This bore 50 comprises twenty-four grooves 51 which are complementary to the grooves of the shafts 19 and 20. These grooves are in profile developing from a circle and allow, because of their number, to position each toothed crown 21 with an angular deviation of 15 ° relative to the neighboring crowns.
  • the hub 23 of a toothed crown 21 can have a thickness exactly equal to the sum of the maximum thicknesses teeth of two crowns, but in this case to prevent seizure and te
  • the different serrated rings must be separated from each other on the same shaft by rings whose internal contour, adapted to the contour of the shaft, can also be grooved.
  • the elasticity of mounting of the grinding shafts could be ensured by guided helical springs replacing the hydraulic cylinders 43.
  • the stacks of the plates 25 and 26 constituting the combs 24 could be replaced by a set of plates 25 carrying on their face currently occupied by the plate 26 a simple welded marginal rib.
