Description

L'invention concerne un broyeur à déchets comprenant au moins un rotor de broyage muni d'organes de broyage tels que des dents rotatives et qui s'étend en partie inférieure et à l'intérieur d'une caisse de broyage traversée par les déchets lors de leur broyage.The invention relates to a waste shredder. comprising at least one grinding rotor provided with grinding such as rotating teeth and which extends into lower part and inside a grinding box crossed by the waste during its grinding.

On connaít déjà de tels broyeurs à déchets mono ou multirotors de formes et dimensions variables en fonction de la nature et du volume des déchets à traiter, et de l usage qui est fait du broyeur. La caisse est généralement formée de quatre parois latérales montées sur un châssis, à savoir deux parois latérales parallèles au(x) rotor(s) et deux parois latérales d'extrémité perpendiculaires au(x) rotor(s) qui traversent au moins une de ces parois. Chaque rotor est porté et guidé à l'extérieur de la caisse et en regard de chaque paroi latérale d'extrémité qu'il traverse, par un palier extérieur monté sur le châssis.We already know such waste shredders mono or multirotors of variable shapes and dimensions in depending on the nature and volume of the waste to be treated, and the use that is made of the grinder. The case is generally formed by four side walls mounted on a frame, namely two side walls parallel to (x) rotor (s) and two end side walls perpendicular to the rotor (s) which pass through at least one of these walls. Each rotor is carried and guided to the exterior of the body and facing each wall lateral end which it crosses, by a landing exterior mounted on the chassis.

En disposant ainsi les paliers à l'extérieur de la caisse, on accroít la durée de vie de ces paliers, on peut laver l'intérieur de la caisse et les rotors à l'eau ou à la vapeur sous pression sans risque pour les paliers, et on peut broyer des déchets en milieu liquide ou sous aspersion de liquide. Par ailleurs, les tolérances de fabrication sévères imposées pour les paliers de guidage du(des) rotor(s) ne sont pas répercutées sur la fabrication de la caisse.By thus arranging the bearings at the outside of the body, we increase the lifespan of these the inside of the box and the safely pressurized water or steam rotors for the bearings, and we can shred waste in the middle liquid or under liquid spray. In addition, severe manufacturing tolerances for bearings of the rotor (s) are not passed on to the manufacture of the case.

Néanmoins, on constate en pratique que les broyeurs à paliers extérieurs sont généralement moins rigides que les broyeurs à paliers intérieurs dont les rotors sont directement montés sur la caisse. En particulier les broyeurs à paliers extérieurs sont sujets aux vibrations, aux déformations et à une usure plus rapide des éléments constitutifs et des assemblages principaux. De plus, la structure porteuse du châssis du broyeur (piètement, charpente, support, dalle, scellement...) est soumise à ces vibrations et déformations.However, it has been observed in practice that external bearing shredders are generally less rigid than internal bearing mills whose rotors are directly mounted on the body. In especially shredders with external bearings are subject vibration, deformation and faster wear main components and assemblies. Of plus, the supporting structure of the mill frame (base, frame, support, slab, sealing ...) is subject to these vibrations and deformations.

L'invention vise donc à pallier ces inconvénients en proposant un broyeur à paliers extérieurs ayant une fiabilité et une longévité accrues. En particulier, l'invention vise à proposer un broyeur à palier extérieur moins sujet aux vibrations et aux déformations.The invention therefore aims to overcome these disadvantages by proposing a crusher with external bearings having increased reliability and longevity. In particular, the invention aims to provide a grinder external bearing less subject to vibrations and deformations.

L'invention vise en outre à proposer un tel broyeur dont la maintenance est facilitée, et notamment dont les éléments constitutifs, et en particulier le(les) rotor(s) peut (peuvent) être démonté(s) sans nécessiter le démontage intégral du broyeur et de la caisse.The invention further aims to provide such a crusher whose maintenance is facilitated, and in particular of which the constituent elements, and in particular the (the) rotor (s) can (can) be dismantled without requiring the full disassembly of the shredder and the body.

Pour ce faire, l'invention concerne un broyeur à déchets comprenant au moins un rotor de broyage s'étendant à l'intérieur d'une caisse de broyage formée de quatre parois latérales montées sur un châssis, au moins un rotor s'étendant à travers au moins une paroi latérale d'extrémité de la caisse et étant porté à l'extérieur de la caisse et en regard de chaque paroi latérale d'extrémité qu'il traverse, par un palier extérieur monté sur le châssis, caractérisé en ce qu'il comporte des moyens rigides de liaison s'étendant entre chaque palier extérieur et la caisse au-dessus du(des) rotor(s), ces moyens rigides de liaison étant fixés rigidement au palier extérieur et à la caisse qu'ils relient.To do this, the invention relates to a waste crusher comprising at least one grinding rotor extending inside a grinding box formed of four side walls mounted on a frame, at least one rotor extending through at least one side wall end of the box and being worn outside the body and opposite each end side wall that it crosses, by an external bearing mounted on the chassis, characterized in that it comprises means rigid connections extending between each outer bearing and the body above the rotor (s), these rigid means of connection being rigidly fixed to the external bearing and to the crate they link.

Avantageusement et selon l'invention, les moyens rigides de liaison sont fixés au sommet du palier, et comportent une plaque rigide horizontale de liaison et une plaque de fixation à la paroi latérale d'extrémité correspondante de la caisse. La plaque de fixation s'étend parallèlement à la paroi latérale d'extrémité, contre cette paroi latérale d'extrémité et à l'intérieur de la caisse.Advantageously and according to the invention, the rigid connection means are fixed to the top of the bearing, and include a rigid horizontal connecting plate and a fixing plate to the end side wall cash desk correspondent. The fixing plate extends parallel to the end side wall, against this end side wall and inside the body.

Par ailleurs et selon l'invention, la plaque de fixation à la paroi latérale d'extrémité comporte, pour chaque rotor traversant cette paroi latérale, une échancrure ouverte vers le bas permettant le montage/le démontage de cette plaque de fixation par-dessus le rotor. De plus, la paroi latérale d'extrémité de la caisse comporte, pour chaque rotor la traversant, une échancrure ouverte vers le haut permettant l'engagement/le dégagement du rotor par le haut. Egalement, chaque palier extérieur est constitué d'un demi-palier inférieur et d'un demi-palier supérieur serrés l'un contre l'autre autour du(des) rotor(s) selon un plan de joint horizontal passant par l'axe (les axes) du(des) rotor(s). Egalement, le broyeur selon l'invention comporte une plaque externe de réception d'un joint et d'un presse-étoupe pour chaque rotor, et cette plaque externe est constituée d'une demi-plaque supérieure et d'une demi-plaque inférieure montées l'une sur l'autre à l'extérieur de chaque paroi latérale d'extrémité et, autour de chaque rotor selon un plan de joint horizontal passant par l'axe (les axes) du(des) rotor(s). Selon l'invention, le broyeur comporte en outre des peignes de raclage interposés entre des dents de broyage portées par chaque rotor et chaque peigne de raclage est constitué d'un demi-peigne supérieur entourant une portion de section supérieure du rotor et d'un demi-peigne inférieur entourant une portion de section inférieure du rotor. Ainsi, le montage et le démontage des pièces maítresses du broyeur selon l'invention (palier, rotor(s), dents de broyage, parois, peignes...) sont grandement facilités. En particulier, on peut démonter chaque rotor par le haut sans avoir à démonter toute la caisse.Furthermore and according to the invention, the fixing plate to the end side wall comprises, for each rotor passing through this wall side, a notch open towards the bottom allowing the mounting / dismounting of this fixing plate over the rotor. In addition, the end side wall of the body includes, for each rotor passing through, a notch open upwards allowing engagement / rotor clearance from above. Also, each outer bearing consists of a lower half-bearing and an upper half bearing tight against each other around the rotor (s) along a horizontal joint plane passing through the axis (axes) of the rotor (s). Also, the grinder according to the invention comprises an external plate of receipt of a seal and a cable gland for each rotor, and this outer plate consists of a half plate upper and lower half plate mounted one on the other outside each side wall end and around each rotor in a plane of horizontal joint passing through the axis (axes) of the rotor (s). According to the invention, the crusher further comprises scraping combs interposed between teeth grinding carried by each rotor and each comb scraping consists of an upper half-comb surrounding a portion of upper section of the rotor and a half-comb lower surrounding a section portion lower rotor. Thus, the assembly and disassembly of the master parts of the crusher according to the invention (bearing, rotor (s), grinding teeth, walls, combs ...) are greatly facilitated. In particular, we can disassemble each rotor from above without having to dismantle the entire checkout.

L'invention concerne aussi un broyeur comportant en combinaison tout ou partie des caractéristiques mentionnées ci-dessus ou ci-après.The invention also relates to a grinder comprising in combination all or part of features mentioned above or below.

Les moyens 8 rigides de liaison sont fixés rigidement d'un côté au sommet du palier 7 extérieur qui porte les deux rotors 1, et de l'autre côté à la paroi latérale d'extrémité 5 qui est traversée par les rotors 1 et qui s'étend en regard du palier 7 extérieur.The rigid connection means 8 are fixed rigidly on one side at the top of the outer bearing 7 which carries the two rotors 1, and on the other side to the wall lateral end 5 which is crossed by the rotors 1 and which extends opposite the outer bearing 7.

Les moyens 8 rigides de liaison sont constitués d'un renfort en équerre 8 formant une plaque 9 rigide horizontale de liaison, et une plaque 10 verticale de fixation à la paroi latérale d'extrémité 5 de la caisse 3. Le palier 7 extérieur comporte une face supérieure horizontale 11, et la plaque 9 de liaison repose et est fixée sur cette face 11 par quatre vis verticales 12 s'étendant à travers des perçages 13 de la plaque 9. Les vis 12 sont engagées dans des taraudages 14 à axe vertical ménagés dans le palier 7. La plaque 9 de liaison a un contour qui correspond à celui de la face supérieure 11 du palier 7, de sorte que cette plaque 9 de liaison recouvre entièrement cette face supérieure 11 sur laquelle elle prend appui.The rigid connection means 8 are consisting of a square reinforcement 8 forming a plate 9 rigid horizontal connection, and a vertical plate 10 fixing to the end side wall 5 of the body 3. The outer bearing 7 has an upper face horizontal 11, and the connecting plate 9 rests and is fixed on this face 11 by four vertical screws 12 extending through holes 13 of the plate 9. The screws 12 are engaged in threads 14 with vertical axis formed in the bearing 7. The connecting plate 9 has a contour which corresponds to that of the upper face 11 of the bearing 7, so that this connecting plate 9 covers entirely this upper face 11 on which it is supported.

Par ailleurs, le palier 7 extérieur est constitué d'un demi-palier inférieur 7a, et d'un demi-palier supérieur 7b, ces deux demi-paliers 7a, 7b étant serrés l'un contre l'autre autour des deux rotors 1 selon un plan de joint horizontal 15 passant par les axes 16 des rotors 1. Les deux demi-paliers 7a, 7b sont serrés l'un contre l'autre par des vis 17 de serrage disposées par paires de chaque côté de chaque rotor 1. Les six vis 17 de serrage s'étendent verticalement vers le bas à travers des perçages 18 verticaux traversants du demi-palier supérieur 7b, et sont engagées dans des taraudages 19 verticaux ménagés dans le demi-palier inférieur 7a.Furthermore, the outer bearing 7 is consisting of a lower half-bearing 7a, and a half-bearing upper 7b, these two half-bearings 7a, 7b being tight against each other around the two rotors 1 according to a horizontal joint plane 15 passing through the axes 16 of the rotors 1. The two half-bearings 7a, 7b are tightened one against each other by clamping screws 17 arranged by pairs on each side of each rotor 1. The six screws 17 of clamp extend vertically downward through 18 vertical through holes of the half bearing upper 7b, and are engaged in tapping 19 verticals arranged in the lower half-bearing 7a.

La plaque 9 de liaison comporte des lumières cylindriques 20 traversantes dans lesquelles les têtes des vis 17 viennent se loger et par lesquelles elles sont accessibles. On peut ainsi au besoin serrer ou desserrer les vis 17 de serrage par le haut sans avoir à démonter les moyens 8 rigides de liaison.The connecting plate 9 includes 20 through cylindrical lights in which the heads of the screws 17 are housed and by which they are accessible. We can thus tighten or loosen the clamping screws 17 from above without having to dismantle the rigid connection means 8.

La caisse 3 de broyage a une hauteur identique à celle des paliers 7 extérieurs. Au besoin, une trémie d'alimentation des déchets peut être montée au-dessus de la caisse 3 de broyage avec des parois latérales verticales ou inclinées prolongeant vers le haut les parois latérales 4, 5 verticales de la caisse 3 de broyage sur lesquelles elles sont montées grâce à des boulons engagés dans des perçages verticaux 62 des parois de la caisse 3. En variante non représentée, les parois 4, 5 latérales de la caisse 3 de broyage peuvent également être légèrement inclinées par rapport à la verticale pour faciliter la circulation des déchets à travers les rotors de broyage.Crushing box 3 has a height identical to that of the outer bearings 7. If necessary, a waste feed hopper can be mounted above of the grinding box 3 with side walls vertical or inclined extending upwards the walls lateral 4, 5 vertical of the crushing box 3 on which they are mounted by means of engaged bolts in vertical holes 62 in the walls of the body 3. In a variant not shown, the side walls 4, 5 of 3 grinding crate can also be slightly inclined to the vertical to facilitate waste circulation through the grinding rotors.

Le chant supérieur 21 horizontal de la paroi latérale d'extrémité 5 est de niveau avec la face supérieure 11 du palier 7 extérieur, et la plaque 9 de liaison repose sur ce chant supérieur 21 horizontal de la paroi latérale 5 d'extrémité.The upper horizontal edge 21 of the end side wall 5 is level with the face upper 11 of the outer bearing 7, and the plate 9 of connection rests on this upper horizontal edge 21 of the end wall 5.

La plaque 10 de fixation à la paroi latérale 5 de la caisse 3 s'étend à l'intérieur de cette caisse 3 verticalement contre la face interne 22 de la paroi latérale d'extrémité 5. La plaque 10 de fixation est soudée à la plaque 9 de liaison ou usinée d'un seul tenant avec cette plaque 9 de liaison. La plaque 9 de liaison est fixée à la paroi latérale 5 par deux vis 23 verticales traversant des perçages 24 de la plaque 9 et engagées dans des taraudages 25 borgnes ménagés dans le chant supérieur 21 de la paroi latérale d'extrémité 5 entre les deux rotors 1. Egalement, le chant supérieur 21 de la paroi latérale d'extrémité 5 est prolongé parallèlement aux axes 16 des rotors et à l'extérieur de la caisse 3 par des extensions 26 horizontales sur lesquelles viennent reposer des ailes latérales 27 de la plaque 9 de liaison. Ces ailes latérales 27 s'étendent horizontalement en saillie dans la direction perpendiculaire aux rotors 1. Des boulons 28 à axes verticaux permettent de serrer les ailes 27 sur les extensions 26.The wall fixing plate 10 side 5 of the body 3 extends inside this body 3 vertically against the internal face 22 of the end side wall 5. The fixing plate 10 is welded to the connecting plate 9 or machined in one piece with this connecting plate 9. The connecting plate 9 is fixed to the side wall 5 by two vertical screws 23 crossing holes 24 of plate 9 and engaged in 25 blind tapped holes in the upper edge 21 of the end side wall 5 between the two rotors 1. Also, the upper edge 21 of the side wall end 5 is extended parallel to axes 16 of rotors and outside the body 3 by extensions 26 horizontal ones on which come to rest wings side 27 of the connecting plate 9. These side wings 27 extend horizontally projecting in the direction perpendicular to the rotors 1. Bolts 28 with axes vertical allow to tighten the wings 27 on the extensions 26.

La plaque 10 de fixation comporte, pour chaque rotor 1 traversant la paroi latérale d'extrémité 5, une échancrure 29 dont l'ouverture est orientée vers le bas et qui permet le montage/le démontage de la plaque 10 de fixation par-dessus les rotors 1. Le sommet 30 de ces échancrures 29 est hémicylindrique et vient entourer le rotor 1 par-dessus. The fixing plate 10 comprises, for each rotor 1 passing through the end side wall 5, a notch 29 whose opening is oriented downwards and which allows the mounting / dismounting of the plate 10 of fixing over the rotors 1. The top 30 of these notches 29 is semi-cylindrical and surrounds the rotor 1 above.

Egalement, la paroi latérale d'extrémité 5 de la caisse 3 comporte, pour chaque rotor 1 la traversant, une échancrure 31 ouverte vers le haut et permettant l'engagement/le dégagement des rotors 1 par le haut. Le fond 32 de ces échancrures 31 est hémicylindrique et entoure par-dessous le rotor 1. Ainsi, chaque rotor 1 est coincé entre l'échancrure 29 de la plaque 10 de fixation, et l'échancrure 31 de la paroi latérale 5.Also, the end side wall 5 of the body 3 comprises, for each rotor 1 passing through it, a notch 31 open at the top and allowing engagement / disengagement of rotors 1 from above. The bottom 32 of these notches 31 is semi-cylindrical and surrounds below the rotor 1. Thus, each rotor 1 is wedged between the notch 29 of the fixing plate 10, and the notch 31 of the side wall 5.

La plaque 10 de fixation est constituée en acier renforcé et/ou recouverte d'un blindage de protection. La plaque 10 de fixation porte un carter 33 supérieur venant recouvrir la première dent de broyage de l'un des deux rotors 1.The fixing plate 10 is made up of reinforced steel and / or covered with armor protection. The fixing plate 10 carries a casing 33 upper covering the first grinding tooth of one of the two rotors 1.

Une plaque externe 34 est rapportée contre la face extérieure de la paroi latérale d'extrémité 5 pour le montage d'un joint 36 d'étanchéité et d'un presse-étoupe 35 autour de chaque rotor 1. Chaque presse-étoupe 35 est constitué d'un demi presse-étoupe supérieur et d'un demi presse-étoupe inférieur, montés l'un sur l'autre avec un plan de joint passant par l'axe 16 du rotor 1. Cette plaque 34 est constituée d'une demi-plaque supérieure 34b et d'une demi-plaque inférieure 34a montées l'une sur l'autre à l'extérieur de la paroi latérale d'extrémité 5 et autour de chaque rotor 1 selon un plan de joint 37 horizontal passant par les axes 16 des rotors 1. Une échancrure 38a hémicylindrique à ouverture orientée vers le haut est ménagée dans la demi-plaque inférieure 34a pour chaque rotor 1. Egalement, une échancrure 38b de section hémicylindrique à ouverture orientée vers le bas est ménagée dans la demi-plaque supérieure 34b pour chaque rotor 1. Ainsi, chaque rotor 1 est emprisonné dans une ouverture cylindrique formée par les échancrures 38a, 38b dans la plaque 34 après serrage des demi-plaques supérieure 34b et inférieure 34a l'une sur l'autre. La demi-plaque inférieure 34a est fixée contre la face externe de la paroi latérale d'extrémité 5 grâce à des vis 40a horizontales engagées à travers des perçages horizontaux 39a de cette demi-plaque inférieure 34a et dont les extrémités libres filetées sont engagées dans des taraudages horizontaux 64 ménagés dans la plaque latérale d'extrémité 5. La demi-plaque supérieure 34b est fixée contre la face externe de la paroi latérale d'extrémité 5 grâce à des vis 40b horizontales engagées à travers des perçages horizontaux 39b de cette demi-plaque supérieure 34b, à travers des perçages horizontaux 63 ménagés à travers la paroi latérale d'extrémité 5, et dont les extrémités libres filetées sont engagées dans des taraudages horizontaux 41 ménagés dans la plaque 10 de fixation. La demi-plaque supérieure 34b est donc assemblée avec la plaque 10 de fixation sur la paroi latérale d'extrémité 5 prise en sandwich entre cette demi-plaque 34b et la plaque 10 de fixation. Les ouvertures cylindriques formées par les échancrures 38a, 38b des demi-plaques 34a, 34b reçoivent un joint 36 d'étanchéité. Un presse-étoupe 35 est engagé dans ces ouvertures cylindriques et fixé par des vis horizontales 42 aux demi-plaques 34a, 34b pour comprimer le joint 36 et assurer l'étanchéité de la caisse 3 au niveau des rotors 1. Les vis 42 sont serrées dans des taraudages des demi-plaques 34a, 34b.An external plate 34 is added against the outer face of the end side wall 5 for mounting a seal 36 and a cable gland 35 around each rotor 1. Each cable gland 35 consists of a half upper cable gland and a lower half cable gland, mounted one on top of the other with a joint plane passing through the axis 16 of the rotor 1. This plate 34 consists of an upper half-plate 34b and a lower half-plate 34a mounted one on the other outside of the end side wall 5 and around each rotor 1 along a joint plane 37 horizontal passing through the axes 16 of the rotors 1. A semi-cylindrical notch 38a with opening oriented towards the top is provided in the lower half-plate 34a for each rotor 1. Also, a notch 38b of section semi-cylindrical with downward opening formed in the upper half-plate 34b for each rotor 1. Thus, each rotor 1 is trapped in a cylindrical opening formed by the notches 38a, 38b in plate 34 after tightening the half-plates upper 34b and lower 34a one on the other. The lower half-plate 34a is fixed against the external face of the end side wall 5 by means of screws 40a horizontal engaged through horizontal holes 39a of this lower half-plate 34a and whose threaded free ends are engaged in horizontal threads 64 arranged in the side plate end 5. The upper half-plate 34b is fixed against the outer face of the end side wall 5 by means of horizontal screws 40b engaged through horizontal holes 39b of this upper half-plate 34b, through horizontal holes 63 formed at through the end side wall 5, and whose threaded free ends are engaged in horizontal threads 41 formed in the plate 10 of fixation. The upper half-plate 34b is therefore assembled with the fixing plate 10 on the side wall end 5 sandwiched between this half-plate 34b and the fixing plate 10. Cylindrical openings formed by the notches 38a, 38b of the half-plates 34a, 34b receive a seal 36. A cable gland 35 is engaged in these cylindrical openings and fixed by horizontal screws 42 to the half-plates 34a, 34b for compress the seal 36 and seal the body 3 at the rotors 1. The screws 42 are tightened in threads of the half-plates 34a, 34b.

Les deux demi-paliers 7a, 7b d'un palier 7 emprisonnent, pour chaque rotor 1, un roulement 43 de guidage de ce rotor 1. Chaque demi-palier inférieur 7a est fixé sur le châssis 6 grâce à des boulons 44. Chaque rotor 1 est prolongé d'un côté de la caisse 3 au-delà du palier 7 pour être accouplé à un moteur 45 porté par le châssis 6.The two half-bearings 7a, 7b of a bearing 7 trap, for each rotor 1, a bearing 43 of guiding this rotor 1. Each lower half-bearing 7a is fixed to the frame 6 by bolts 44. Each rotor 1 is extended on one side of the body 3 beyond the bearing 7 to be coupled to a motor 45 carried by the chassis 6.

Le broyeur comporte en outre des peignes 46 de raclage interposés entre les dents de broyage 2 qui sont portées par chaque rotor 1. Chaque peigne 46 de raclage est constitué d'un demi-peigne supérieur 46b entourant une portion de section supérieure du rotor 1, et d'un demi-peigne inférieur 46a entourant une portion de section inférieure du rotor 1. Chaque demi-peigne 46a, 46b est formé d'une plaque s'étendant dans un plan radial à l'axe 16 du rotor 1. Les deux demi-peignes 46a, 46b sont montés l'un au-dessus de l'autre selon un plan de joint 47 horizontal passant par les axes 16 du rotor 1. Et les deux demi-peignes 46a, 46b sont fixés ensemble rigidement mais de façon amovible sur une paroi latérale 4 de la caisse 3 parallèle au rotor 1 grâce à une cornière de fixation commune 48 horizontale interposée entre eux et s'étendant à l'intérieur de cette paroi latérale 4 sur laquelle elle est montée par des vis de serrage 49 horizontales accessibles de l'extérieur de la caisse 3. La cornière 48 de fixation commune forme des rails longitudinaux supérieur 50 et inférieur 51 engagés dans des évidements 52, 53 correspondants du demi-peigne supérieur 46b, respectivement du demi-peigne inférieur 46a. Les demi-peignes supérieurs 46b sont également fixés grâce à une cornière supérieure 54 horizontale s'étendant à l'intérieur de la paroi latérale 4 sur laquelle elle est montée par des vis de serrage 55 accessibles de l'extérieur. Cette cornière supérieure 54 définit un rail 56 engagé dans un évidement 57 ménagé à l'angle supérieur de chaque demi-peigne supérieur 46b. De même, chaque demi-peigne inférieur 46a est fixé par une cornière inférieure 58 horizontale montée à l'intérieur de la paroi latérale 4 par des vis de serrage 59 accessibles de l'extérieur. La cornière inférieure 58 définit un rail 60 engagé dans un évidement 61 ménagé au coin inférieur de chaque demi-peigne 46a. Ainsi, tous les peignes 46 sont fixés sur la paroi latérale 4 parallèle à et en regard du rotor 1 par les cornières 48, 54, 58 de fixation s'étendant le long et à l'intérieur de la paroi latérale 4 sur laquelle elles sont montées par des vis 49, 55, 59 accessibles de l'extérieur de la caisse 3. Ainsi, chaque demi-peigne 46a, 46b peut être démonté simplement en desserrant les vis 49 de serrage de la cornière commune 48 et en ôtant la cornière supérieure 54 ou la cornière inférieure 58. Ce démontage peut être effectué sans avoir à démonter les rotors 1. Les demi-peignes supérieurs sont dégagés par le haut et les demi-peignes inférieurs sont dégagés par le bas.The crusher further comprises combs 46 scrapers interposed between the grinding teeth 2 which are carried by each rotor 1. Each scraper comb 46 is consisting of an upper half-comb 46b surrounding a upper section of rotor 1, and a half-comb lower 46a surrounding a section portion lower rotor 1. Each half-comb 46a, 46b is formed of a plate extending in a radial plane to the axis 16 of the rotor 1. The two half-combs 46a, 46b are mounted one above the other along a parting line 47 horizontal passing through the axes 16 of the rotor 1. And the two half-combs 46a, 46b are rigidly fixed together but removably on a side wall 4 of the body 3 parallel to rotor 1 thanks to a fixing angle common 48 horizontal interposed between them and extending to the interior of this side wall 4 on which it is mounted by accessible horizontal clamping screws 49 from outside the box 3. The fixing angle 48 joint forms upper longitudinal rails 50 and lower 51 engaged in recesses 52, 53 correspondents of the upper half-comb 46b, respectively of the lower half-comb 46a. The upper half-combs 46b are also fixed by an upper angle 54 horizontal extending inside the side wall 4 on which it is mounted by clamping screws 55 accessible from the outside. This upper angle 54 defines a rail 56 engaged in a recess 57 formed at the upper angle of each upper half-comb 46b. Of even, each lower half-comb 46a is fixed by a horizontal bottom angle 58 mounted inside the side wall 4 by accessible clamping screws 59 from the outside. The bottom angle 58 defines a rail 60 engaged in a recess 61 formed at the lower corner of each half-comb 46a. So all the combs 46 are fixed on the side wall 4 parallel to and facing the rotor 1 by the fixing angles 48, 54, 58 extending along and inside the side wall 4 on which they are mounted by screws 49, 55, 59 accessible from outside the box 3. Thus, each half-comb 46a, 46b can be removed simply by loosening the screws 49 for tightening the common angle iron 48 and by removing the upper angle 54 or the angle lower 58. This disassembly can be carried out without having to remove the rotors 1. The upper half-combs are released from the top and the lower half-combs are released from below.

Le broyeur 1 selon l'invention peut être aisément et rapidement monté et démonté, ce qui facilite sa maintenance et diminue les coûts de main-d'oeuvre. Il est néanmoins d'une extrêmement grande rigidité et peut supporter des puissances importantes relativement à ses dimensions. En outre, la plaque 9 de liaison horizontale a également pour fonction de protéger les joints 36 et les presse-étoupes 35 de sortie des rotors 1 et les roulements 43 des paliers 7 des projections de liquide, notamment celles qui proviendraient de la trémie supérieure.The mill 1 according to the invention can be easily and quickly assembled and disassembled, which facilitates its maintenance and lowers labor costs. It is nevertheless extremely rigid and can bear significant powers relative to its dimensions. In addition, the horizontal connecting plate 9 has also to protect the seals 36 and the cable glands 35 for output from rotors 1 and bearings 43 of the bearings 7 of the liquid projections, especially those that come from the hopper superior.

L'invention est applicable également à tout autre type de broyeur que celui représenté sur les figures. En particulier, le nombre des rotors peut être différent, et le broyeur peut comporter un rotor ou plus de deux rotors.The invention is also applicable to any another type of grinder than that shown in the figures. In particular, the number of rotors can be different, and the mill can have one rotor or more than two rotors.
