Description

La présente invention concerne des perfectionnements apportés aux concasseurs à percussion à marteaux articulés.The present invention relates to improvements made to impact crushers with articulated hammers.

On connaît déjà des concasseurs de ce genre dont le rotor est constitué par un empilage de disques angulairement décalés qui sont montés sur un arbre au moyen duquel ils sont entraînés en rotation à l'intérieur d'une chambre de concassage. Ces disques sont percés sur leur périphérie de manière à être traversés par des axes autour desquels sont articulés les marteaux dont les parties actived sont en saillie par rapport aux disques.Crushers of this type are already known, the rotor of which consists of a stack of angularly offset discs which are mounted on a shaft by means of which they are driven in rotation inside a crushing chamber. These discs are drilled on their periphery so as to be crossed by axes around which the hammers are articulated, the actived parts of which project from the discs.

L'invention a surtout pour but de réaliser l'empilage usuel sous la forme d'un ensemble monobloc apte à être monté d'une seule pièce sur l'arbre du concasseur. Elle vise en outre à réaliser le rotor du concasseur sous la forme d'un tambour rigide à forte inertie.The main object of the invention is to produce the usual stacking in the form of a one-piece assembly able to be mounted in one piece on the crusher shaft. It also aims to produce the crusher rotor in the form of a rigid drum with high inertia.

L'invention a plus précisément pour objet un concasseur à percussion à marteaux articulés comprenant un empilage de plateaux angulairement décalés qui est monté sur l'arbre du concasseur, lesdits plateaux supportant les axes d'articulation des marteaux, caractérisé en ce que les plateaux successifs de l'empilage sont soudés entr'eux, deux plateaux adjacents étant soudés suivant la partie du contour de l'un des plateaux délimitant sa zone de contact avec l'autre plateau, de telle sorte que l'empilage constitue un ensemble monobloc.The invention more specifically relates to an impact crusher with articulated hammers comprising a stack of angularly offset plates which is mounted on the crusher shaft, said plates supporting the axes of articulation of the hammers, characterized in that the successive plates of the stack are welded between them, two adjacent plates being welded along the part of the contour of one of the plates delimiting its zone of contact with the other plate, so that the stack constitutes a monobloc assembly.

L'empilage est avantageusement monté entre deux disques formant volants d'inertie, qui sont respectivement soudés aux plateaux d'extrémité dudit empilage avec lequel ils constituent un tambour.The stack is advantageously mounted between two discs forming flywheels, which are respectively welded to the end plates of said stack with which they constitute a drum.

Les plateaux sont avantageusement conformés de telle sorte que deux.plateaux adjacents présentent des contours ayant_ des parties communes, le soudage étant effectué le long desdites parties communes.The plates are advantageously shaped so that two adjacent plates have contours having_ common parts, the welding being carried out along said common parts.

Suivant une disposition caractéristique de l'invention, chaque plateau présente la forme de deux secteurs circulaires opposés d'un angle au centre de 90°, qui sont raccordés par une partie centrale de forme annulaire, de telle sorte que, les plateaux étant successivement décalés de 90°, les arêtes rectilignes des secteurs circulaires de deux plateaux adjacents constituent lesdites parties communes des contours.According to a characteristic arrangement of the invention, each plate has the shape of two circular sectors opposite by an angle at the center of 90 °, which are connected by a central part of annular shape, so that, the plates being successively offset 90 °, the rectilinear edges of the circular sectors of two adjacent plates constitute said common parts of the contours.

Chaque plateau est avantageusement formé par une tôle découpée.Each plate is advantageously formed by a cut sheet.

Chaque disque est également formé par une tôle découpée.Each disc is also formed by a cut sheet.

Les plateaux et les disques sont percés sur leur périphérie de trous disposés en coïncidence, de manière à être traversés par les axes d'articulation des marteaux et par des axes de butée desdits marteaux.The plates and the discs are pierced on their periphery with holes arranged in coincidence, so as to be crossed by the axes of articulation of the hammers and by axes of abutment of said hammers.

Le tambour est monté sur l'arbre du concasseur par l'intermédiaire de moyens de frettage, par exemple.The drum is mounted on the crusher shaft by means of hooping means, for example.

L'invention sera mieux comprise en se référant à la description qui suit, faite en regard des dessins annexés, concernant une forme particulière de réalisation donnée à titre d'exemple non limitatif.

  • La figure 1 est une vue en élévation du rotor du concasseur représenté partiellement en coupe. ,
  • La figure 2 en est une coupe transversale suivant la ligne A-A de la figure 1.
  • La figure 3 représente un plateau de l'empilage.
  • La figure 4 représente un disque d'extrémité rapporté sur l'empilage.
  • La figure 5 est une vue du tambour formé par l'empilage et les deux disques d'extrémité.
The invention will be better understood by referring to the description which follows, given with reference to the appended drawings, concerning a particular embodiment given by way of nonlimiting example.
  • Figure 1 is an elevational view of the crusher rotor shown partially in section. ,
  • Figure 2 is a cross section along line AA of Figure 1.
  • Figure 3 shows a stacking tray.
  • Figure 4 shows an end disc attached to the stack.
  • Figure 5 is a view of the drum formed by the stack and the two end discs.

Sur les figures, on voit un tambour constitué par deux disques, tels que 1, formant volants d'inertie, disposés de part et d'autre d'un empilage de plateaux, tels que 2. Ce tambour est entraîné en rotation par un arbre 7 traversant axialement les disques 1 et les plateaux 2. L'arbre 7 est monté sur des paliers tels que 9 solidaires des parties fixes du concasseur. La liaison entre l'arbre 7 et le tambour est assurée, par exemple, par des dispositifs de frettage 8 montés dans des logements 13 des disques 1.In the figures, we see a drum constituted by two discs, such as 1, forming flywheels, arranged on either side of a stack of plates, such as 2. This drum is rotated by a shaft 7 axially passing through the discs 1 and the plates 2. The shaft 7 is mounted on bearings such as 9 secured to the fixed parts of the crusher. The connection between the shaft 7 and the drum is ensured, for example, by hooping devices 8 mounted in housings 13 of the discs 1.

Chaque plateau 2 présente la forme de deux secteurs circulaires 2 a et 2 b en opposition, d'un angle au centre de 90°, lesdits secteurs étant reliés par une partie centrale 2 c de forme annulaire. Le repère 14 désigne l'orifice central du plateau 2 correspondant au diamètre de l'arbre 7.Each plate 2 has the shape of two circular sectors 2 a and 2 b in opposition, at an angle at the center of 90 °, said sectors being connected by a central part 2 c of annular shape. The reference 14 designates the central orifice of the plate 2 corresponding to the diameter of the shaft 7.

Ces plateaux sont obtenus par oxycoupage de tôles.These plates are obtained by flame cutting of sheets.

Les plateaux successifs de l'empilage sont successivement décalés de 90° de telle sorte que les arêtes rectilignes, telles que 2 d et 2 e, d'un plateau 2 viennent en coinci- dence avec les arêtes rectilignes homologues des plateaux voisins.The successive plates of the stack are successively offset by 90 ° so that the rectilinear edges, such as 2 d and 2 e, of a plate 2 come into coincidence with the homologous rectilinear edges of the neighboring plates.

Deux plateaux adjacents, tels que 2, sont soudés suivant la partie du contour de l'un des deux plateaux délimitant sa zone de contact avec l'autre plateau, soit suivant le contour de la partie annulaire 2 c raccordant les arêtes rectilignes, telles que 2 d et 2 e, et suivant lesdites arêtes, ces dernières constituant des parties communes aux contours desdits plateaux adjacents. Les plateaux 2 peuvent être facilement soudés les uns sur les autres, l'empilage étant ainsi réalisé par des opérations successives de soudage à partir d'un premier plateau.Two adjacent plates, such as 2, are welded along the part of the contour of one of the two plates delimiting its zone of contact with the other plate, or following the contour of the annular part 2 c connecting the rectilinear edges, such that 2 d and 2 e, and along said edges, the latter constituting parts common to the contours of said adjacent plates. The plates 2 can be easily welded to one another, the stacking being thus produced by successive welding operations from a first tray.

Les disques 1 sont respectivement soudés aux plateaux d'extrémité de l'empilage. Ils sont, comme lesdits plateaux, obtenus par oxycoupage de tôles. Le repère 15 désigne leur orifice central de même diamètre que l'orifice 14.The discs 1 are respectively welded to the end plates of the stack. They are, like said plates, obtained by flame cutting of sheets. The reference 15 designates their central orifice of the same diameter as the orifice 14.

Chaque disque 1 est percé sur sa périphérie de huit trous 11, tandis que chaque plateau 2 est percé sur sa périphérie de quatre trous 12, soit deux trous à travers le secteur 2 a et deux trous à travers le secteur 2 b. Les huit trous 11 sont disposés en coïncidence avec les quatre trous 12 des plateaux 2 de même orientation, et avec les quatre trous homologues des plateaux 2 décalés de 90* par rapport aux précédents.Each disc 1 is pierced on its periphery with eight holes 11, while each plate 2 is pierced on its periphery with four holes 12, ie two holes through sector 2 a and two holes through sector 2 b. The eight holes 11 are arranged in coincidence with the four holes 12 of the plates 2 of the same orientation, and with the four homologous holes of the plates 2 offset by 90 * with respect to the previous ones.

Les trous 11 et 12 permettent la traversée de l'empilage des plateaux 2 et des disques 11 par des axes qui sont immobilisés axialement par tout moyen usuel sur les faces extérieures des disques 1.The holes 11 and 12 allow the stacking of the plates 2 and the disks 11 to pass through by axes which are immobilized axially by any usual means on the external faces of the disks 1.

Quatre axes 3 supportent des marteaux 5 articulés autour desdits axes, entre les plateaux 2 de même orientation, à l'extérieur des plateaux 2 intermédiaires décalés par rapport aux précédents. L'épaisseur des plateaux 2 est égale, au jeu près, à celle des marteaux 5. Deux axes 3 traversent respectivement les secteurs 2 a et 2 b des plateaux 2 de même orientation, tandis que deux axes 3 traversent respectivement les secteurs 2 a et 2 b des plateaux 2 décalés par rapport aux précédents.Four axes 3 support hammers 5 articulated around said axes, between plates 2 of the same orientation, outside of intermediate plates 2 offset from the previous ones. The thickness of the plates 2 is equal, apart from the clearance, to that of the hammers 5. Two axes 3 respectively cross sectors 2 a and 2 b of plates 2 of the same orientation, while two axes 3 respectively cross sectors 2 a and 2 b of the plates 2 offset from the previous ones.

Quatre axes 4 traversent de manière analogue les plateaux 2 de l'empilage, de sorte que chaque secteur 2 a ou 2 b est traversé par un axe 3 et un axe 4. Ce dernier constitue un axe de butée muni de rondelles 6 sur lesquelles les marteaux 5 articulés sur l'axe 3 coopérant, prennent appui chaque fois qu'un corps particulièrement difficile à broyer provoque la rotation d'un marteau 5.Four axes 4 pass through the plates 2 of the stack in an analogous manner, so that each sector 2 a or 2 b is crossed by an axis 3 and an axis 4. The latter constitutes a stop axis provided with washers 6 on which the hammers 5 articulated on the cooperating axis 3, bear each time a body which is particularly difficult to grind causes the rotation of a hammer 5.

Les dispositions que l'on vient de décrire présentent de nombreux avantages.The arrangements just described have many advantages.

Elles autorisent une construction particulièrement simple. Les seules opérations d'usinage consistent au perçage des trous 11 et 12 et à l'usinage des portées des logements 13. Le tambour ainsi réalisé possède une forte inertie.They allow a particularly simple construction. The only machining operations consist of drilling holes 11 and 12 and machining the bearing surfaces of the housings 13. The drum thus produced has a high inertia.

L'invention est applicable à tous les rotors de concasseurs ou broyeurs à marteaux articulés auxquels on n'impose pas un éclipsage complet des marteaux. Le concasseur suivant l'invention est particulièrement adapté au broyage des ordures ménagères.The invention is applicable to all the rotors of crushers or articulating hammer mills which do not require complete eclipse of the hammers. The crusher according to the invention is particularly suitable for shredding household waste.

Bien que l'invention ait été décrite en référence à une forme particulière de réalisation, il va de soi qu'elle n'y est en rien limitée, et que des modifications peuvent lui être apportées sans sortir de son domaine.Although the invention has been described with reference to a particular embodiment, it goes without saying that it is in no way limited thereto, and that modifications can be made to it without departing from its field.

Les plateaux pourront être réalisés suivant une forme différente de celle décrite. Les décalages angulaires successifs desdits plateaux pourront différer de 90*. The trays can be produced in a form different from that described. The successive angular offsets of said plates may differ from 90 *.

On pourra, bien entendu, remplacer l'un quelconque des moyens décrits par un moyen techniquement équivalent.We can, of course, replace any of the means described by a technically equivalent means.

L'invention couvre donc, outre l'exemple représenté, ses différentes variantes d'exécution possibles.The invention therefore covers, in addition to the example shown, its various possible alternative embodiments.
