Definitions
- an industrial mill comprising a casing which has on the one hand two fixed vertical walls connected by inverted U-shaped frames and between which is mounted a hammer rotor with horizontal axis to which the products to be ground are brought by a loading hopper, and on the other hand a grid made of two halves separable from each other and each of which is fixed to a door capable of sliding, along two horizontal rails, perpendicularly to the rotor axis.
- a crusher according to the invention is characterized in that: a) the fixed casing has the shape of a trunk of a pyramid whose small base is at the top; b) each inverted U-shaped frame has “vertical” sides with an L-shaped section through horizontal planes, the upper part of which forms the base of the U; and c) a horizontal guide device located at an appropriate height with respect to the fixed casing serves as a raceway for the doors, which extend almost over the entire height of the casing and are preferably suspended.
- the grinder according to the invention comprises a fixed casing 1 in the form of a pyramid trunk, the small base of which is at the top and consists of two rectangular frames inclined towards one another as shown in the figs. 1, 3 and 4, the "vertical" sides 1a of which have a cross section at C by horizontal planes and are connected at their upper end by planar parts 1b (figs. 1 and 2).
- These frames are also, to form the casing, connected by horizontal crosspieces 1c (figs. 1 and 2), by vertical plates 1d (figs. 1 and 3) and by horizontal fixed plates 1e (figs. 1 to 3 and 5) slightly projecting outwards.
- the two frames are connected at their lower end by a base 2 to which they are fixed and which rests on a suitable support 3 inside which is a tank 4 for receiving and evacuating the ground products (figs. 2 and 3).
- the parts 1b of the casing 1 constitute the base of an inverted U whose branches are the crossbeams 1c and the plates 1d.
- the chimney 5 of the crusher and its loading hopper 6 (figs. 1 and 2) are essentially supported by these branches.
- the walls formed by the plates 1d carry bearings 8 for the rotor 9 of the mill, which will be described in more detail below, and the shaft 10 of which is actuated from a motor 11 mounted on a support 12 (fig. 1) via a coupling 13.
- Elements 3, 5 to 7 and 11 to 13 are not part of the invention and will therefore not be described in more detail.
- the branches of the U also support a rectangular horizontal frame designated as a whole by 14 and which serves as a raceway for an opening casing formed by two doors 15 around the top at which are fixed members 16 connected by a horizontal crosspiece 17 the ends of which can slide by any means, for example rollers 18 (figs. 3 and 4), along the long sides 14a of the frame 14.
- the doors 15 can be locked in the closed position by locking devices which will be described later.
- the raceways for the doors 15 are not necessarily located at the top of the fixed casing but may include guide devices fixed to the casing 1 at any suitable height, and other except that the locking closing devices can be of any type whatsoever.
- the fixed casing 1 is internally reinforced by lateral shields 20 to 22, while the opening casing, 2 that is to say the doors 15, comprises transverse shielding plates 23, 24 located above the halves 25 of the grinder grid, which are detachably fixed, by pins 26, to the lower part of each door 15.
- Grid guides 27 integral with the fixed casing 1 facilitate the positioning of the halves of the grid when sliding inwards of the doors 15 along the raceways 14a of the frame 14.
- Each closing device 19 comprises a horizontal lock 28 (figs. 1 to 4 and 6) integral with the associated door 15, and pierced with a notch 29 (figs. 2 and 6) to receive an element of the body a tightening handwheel 30 pivoted at 31 to the fixed casing 1.
- the handwheel 30 is rotated until the tightening is sufficient to allow four pins 32 to be introduced into holes 33 provided in the sides 1a of the casing 1.
- the pins 32 are removed and, by loosening the handwheel 30, the door 15 of the casing is released.
- the wheel 30 is rotated until its axis can come out of the notch 29, and it is then pivoted around the axis 31 so as to move it away from the door (as seen left of Fig. 4). We can then slide the door 15 along the raceways 14a.
- the rotor 9 which includes the motor shaft 10 and a sub-assembly consisting of a cylinder 34 coaxial with the shaft 10, which is connected to it by seals 35 held by pins 36, and which carries itself parallel axes 37 (fig. 4), only two of which are visible in fig. 5, for hammers 38.
- the rotor 9 is temporarily supported by any suitable means, until its axis coincides with that of the bearings 8. The shaft 10 is then introduced, the pins 36 are put in place, and the temporary support system is dismantled.
- vents 39 (FIG. 3) which allow air to enter the sides of the rotor in order to avoid jamming of the products between the rotor and the casing, which reduces wear, facilitates possible sorting and increases the oxygenation of the products.

Abstract
Description
Par le brevet US-A-2 975 985, on connaît un broyeur industriel comprenant un carter qui possède d'une part deux parois verticales fixes reliées par des cadres en U renversé et entre lesquelles est monté un rotor à marteaux à axe horizontal auquel les produits à broyer sont amenés par une trémie de chargement, et d'autre part une grille faite de deux moitiés séparables l'une de l'autre et dont chacune est fixée à une porte capable de coulisser, le long de deux rails horizontaux, perpendiculairement à l'axe du rotor.By US-A-2 975 985, an industrial mill is known comprising a casing which has on the one hand two fixed vertical walls connected by inverted U-shaped frames and between which is mounted a hammer rotor with horizontal axis to which the products to be ground are brought by a loading hopper, and on the other hand a grid made of two halves separable from each other and each of which is fixed to a door capable of sliding, along two horizontal rails, perpendicularly to the rotor axis.
Lorsqu'on utilise ce broyeur, il se pose des problèmes pour accéder facilement à son intérieur, notamment pour procéder à un nettoyage rapide en cas de bourrage ou au remplacement de marteaux usés, de plaques d'usure ou de grilles.When using this crusher, problems arise for easy access to its interior, in particular for rapid cleaning in the event of jamming or replacement of worn hammers, wear plates or grids.
Ces problèmes sont résolus d'après l'invention en modifiant la structure du broyeur proprement dit, c'est-à-dire du carter contenant le rotor et les grilles, et en le munissant de portes à accès faciles.These problems are solved according to the invention by modifying the structure of the mill itself, that is to say the casing containing the rotor and the grids, and by providing it with easily accessible doors.
Un broyeur suivant l'invention est caractérisé en ce que: a) le carter fixe a la forme d'un tronc de pyramide dont la petite base se trouve en haut; b) chaque cadre en U renversé possède des côtés «verticaux» à section en L par des plans horizontaux et dont la partie supérieure forme la base de l'U; et c) un dispositif horizontal de guidage situé à une hauteur appropriée par rapport au carter fixe sert de chemin de roulement pour les portes, qui s'étendent pratiquement sur toute la hauteur du carter et sont de préférence suspendus.A crusher according to the invention is characterized in that: a) the fixed casing has the shape of a trunk of a pyramid whose small base is at the top; b) each inverted U-shaped frame has “vertical” sides with an L-shaped section through horizontal planes, the upper part of which forms the base of the U; and c) a horizontal guide device located at an appropriate height with respect to the fixed casing serves as a raceway for the doors, which extend almost over the entire height of the casing and are preferably suspended.
Sur les dessins annexés, on a représenté schématiquement et à titre d'exemple un mode de réalisation de l'invention.
- La fig. 1 est une perspective du broyeur proprement dit, avec seulement la partie inférieure de la cheminée comprenant la trémie de chargement et la partie inférieure de la goulotte d'évacuation des déchets non broyables.
- La fig. est une élévation latérale, suivant la flèche Il des figs. 1 et3, du broyeur proprement dit, avec seulement la partie inférieure de la cheminée mais sans la goulotte d'évacuation des déchets non broyables, et sans le moteur qui actionne le rotor.
- La fig. 3 est une élévation latérale du broyeur proprement dit, suivant la flèche III des figs. 1 et 2.
- La fig. 4 est une coupe verticale par IV-IV de la fig. 2 et montre une des portes ouverte.
- La fig. 5 est une coupe verticale par V-V des figs. 3 et 4.
- La fig. 6 est une coupe horizontale par VI-VI de la fig. 3.
- Fig. 1 is a perspective of the actual mill, with only the lower part of the chimney comprising the loading hopper and the lower part of the discharge chute for non-grindable waste.
- Fig. is a side elevation, along the arrow Il of figs. 1 and 3, of the mill itself, with only the lower part of the chimney but without the discharge chute for non-grindable waste, and without the motor which actuates the rotor.
- Fig. 3 is a side elevation of the mill itself, according to arrow III in FIGS. 1 and 2.
- Fig. 4 is a vertical section through IV-IV of FIG. 2 and shows one of the doors open.
- Fig. 5 is a vertical section through VV of FIGS. 3 and 4.
- Fig. 6 is a horizontal section through VI-VI of FIG. 3.
Sur les figs. 1 à 3, on voit que le broyeur suivant l'invention comprend un carter fixe 1 en forme de tronc de pyramide dont la petite base se trouve en haut et constitué par deux cadres rectangulaires inclinés l'un vers l'autre comme le montrent les figs. 1, 3 et 4, dont les côtés «verticaux» 1a sont à section en C par des plans horizontaux et sont reliés à leur extrémité supérieure par des parties planes 1b (figs. 1 et 2). Ces cadres sont également, pour former le carter, reliés par des traverses horizontales 1c (figs. 1 et 2), par des plaques verticales 1d (figs. 1 et 3) et par des plaques fixes horizontales 1e (figs. 1 à 3 et 5) légèrement en saillie vers l'extérieur. Les deux cadres sont reliés à leur extrémité inférieure par une base 2 à laquelle ils sont fixés et qui repose sur un support approprié 3 à l'intérieur duquel se trouve une cuve 4 de réception et d'évacuation des produits broyés (figs. 2 et 3). Les parties 1 b du carter 1 constituent la base d'un U renversé dont les branches sont les traverses 1c et les plaques 1d. La cheminée 5 du broyeur et sa trémie de chargement 6 (figs. 1 et 2) sont supportées essentiellement par ces branches. Sur la fig. 1, on voit en outre en 7 la goulotte d'évacuation des déchets non broyables. Les parois constituées par les plaques 1d portent des paliers 8 pour le rotor 9 du broyeur, qui sera décrit plus en détail ci-après, et dont l'arbre 10 est actionné depuis un moteur 11 monté sur un support 12 (fig. 1) par l'intermédiaire d'un accouplement 13. Les éléments 3, 5 à 7 et 11 à 13 ne font pas partie de l'invention et ne seront donc pas décrits plus en détail.In figs. 1 to 3, it can be seen that the grinder according to the invention comprises a
D'après une caractéristique importante de l'invention, les branches de l'U supportent également un cadre horizontal rectangulaire désigné dans son ensemble par 14 et qui sert de chemin de roulement à un carter ouvrant formé de deux portes 15 aux environs du sommet auxquelles sont fixés des organes 16 reliés par une traverse horizontale 17 dont les extrémités peuvent coulisser par n'importe quel moyen par exemple des galets 18 (figs. 3 et 4), le long des grands côtés 14a du cadre 14. Les portes 15 peuvent être bloquées en position fermée par des dispositifs de verrouillage qui seront décrits plus loin. Il est toutefois évident que, d'une part, les chemins de roulement pour les portes 15 ne sont pas forcément situés au sommet du carter fixe mais peuvent comprendre des dispositifs de guidage fixés au carter 1 à une hauteur quelconque appropriée, et d'autre part que les dispositifs de fermeture de verrouillage peuvent être d'un type absolument quelconque.According to an important characteristic of the invention, the branches of the U also support a rectangular horizontal frame designated as a whole by 14 and which serves as a raceway for an opening casing formed by two
Sur les figs. 4 à 6, on voit que le carter fixe 1 est renforcé intérieurement par des blindages latéraux 20 à 22, tandis que le carter ouvrant, 2 c'est-à-dire les portes 15, comporte des plaques transversales de blindage 23, 24 situées au-dessus des moitiés 25 de la grille du broyeur, qui sont fixées de façon amovible, par des goupilles 26, à la partie inférieure de chaque porte 15. Des guides de grille 27 solidaires du carter fixe 1 facilitent la mise en place des moitiés de la grille lors du coulissement vers l'intérieur des portes 15 le long des chemins de roulement 14a du cadre 14.In figs. 4 to 6, it can be seen that the
Chaque dispositif de fermeture 19 comprend un verrou horizontal 28 (figs. 1 à 4 et 6) solidaire de la porte 15 associée, et percé d'une entaille 29 (figs. 2 et 6) pour recevoir un élément du corps d'un volant de serrage 30 pivoté en 31 au carter fixe 1. Pour fermer la porte, on fait tourner le volant 30 jusqu'à ce que le serrage soit suffisant pour permettre d'introduire quatre goupilles 32 dans des trous 33 ménagés dans les côtés 1a du carter 1. Pour ouvrir, on retire les goupilles 32 et, en desserrant le volant 30, on débloque la porte 15 du carter. Aussitôt débloqué, on fait tourner le volant 30 jusqu'à ce que son axe puisse sortir de l'entaille 29, et on le fait alors pivoter autour de l'axe 31 de façon à l'écarter de la porte (comme on le voit à gauche de la fig. 4). On peut alors faire coulisser la porte 15 le long des chemins de roulement 14a.Each
Enfin, sur la fig. 5 et accessoirement sur les figs. 3 et 4, on voit le rotor 9 qui comprend l'arbre moteur 10 et un sous-ensemble constitué par un cylindre 34 coaxial à l'arbre 10, qui lui est relié par des joints 35 maintenus par des goupilles 36, et qui porte lui-même des axes parallèles 37 (fig. 4), dont deux seulement sont visibles sur la fig. 5, pour des marteaux 38. D'après une caractéristique de l'invention, le rotor 9 est supporté provisoirement par tout moyen approprié, jusqu'à ce que son axe coïncide avec celui des paliers 8. On introduit alors l'arbre 10, on met en place les goupilles 36, et l'on démonte le système de support provisoire.Finally, in fig. 5 and incidentally in figs. 3 and 4, we see the
Sur les flancs du carter fixe 1, de chaque côté du rotor 9, sont prévues des ouïes 39 (fig. 3) qui permettent une entrée d'air sur les côtés du rotor afin d'éviter un coincement des produits entre le rotor et le carter, ce qui réduit l'usure, facilite un tri éventuel et permet d'augmenter l'oxygénation des produits.On the sides of the
De plus, grâce au mouvement giratoire du rotor, on obtient une meilleure expulsion des produits à travers la grille 25. En contrepartie, il existe une pression dans la cheminée 5, et en conséquence tous les produits légers, par exemple des plastiques ou de petits morceaux de papier, sont en suspension dans celle-ci. Un système d'aspiration (non représenté) de type quelconque est prévu sur la cheminée pour l'élimination de ces produits légers, et permet d'éliminer un pourcentage important des plastiques, qui, une fois broyés, sont très difficiles à éliminer et nuisent à la bonne présentation de composts destinés à l'agriculture. La cheminée 5 a l'avantage d'oxygéner les ordures pendant leur broyage grâce à la quantité d'air contenue dans celle-ci. L'expérience a permis de constater que dans des broyeurs à cheminée, les ordures en putréfaction ressortaient sans les odeurs nauséabondes qu'elles ont en entrant. Au contraire, dans un broyeur classique sans cheminée, ce phénomène n'existe pas, ce qui prouve surabondamment une oxygénation rapide des produits.In addition, thanks to the rotational movement of the rotor, a better expulsion of the products is obtained through the
