Abstract

The washing installation is for materials such as sand and gravel. A feed pipe (7) supplies washing water and there are conveyors (11) for the material (10) and an inclined surface (14) to collect and transport the washed material towards the feed pipe. A set of spaced rotors (1) are spaced from each other, fitted one one shaft (13). Each rotor has several transverse annular diaphragms (2) which define with the rotor side wall, annular channels (3). Each channel has several buckets on its periphery so that the washing water goes towards the diaphragm exterior at the rotor bottom and against the direction of material movement.

Description

L'invention concerne une installation de lavage de matières inertes telles que du sable, du gravier ou des matières similaires.The invention relates to an installation for washing inert materials such as sand, gravel or the like.

On.sait qu'il faut laver les matières inertes, en particulier les matériaux de construction, afin d'en éliminer la boue, le filler, le limon, la poussière et les substances organiques. Dans ce but, existent actuellement des installations à vis d'Archimède principalement constituées par un bac allongé, légèrement incliné par rap→ port à l'horizontale et dans lequel tourne la vis d'Archimède. La matière à laver est amenée en face de l'extrémité la plus basse du bac et le liquide de lavage, en général de l'eau, est apporté en correspondance de l'extrémité la plus haute du dit bac. L'alimentation étant continue, le liquide de lavage passe par dessus le bord le plus bas et entraîne les impuretés contenues dans la matière inerte qui, transportée par la vis d'Ar- chimède, atteint l'extrémité la plus haute d'où elle est déchargée.We know that it is necessary to wash inert materials, in particular construction materials, in order to remove mud, filler, silt, dust and organic substances. To this end, there are currently Archimedes screw installations mainly consisting of an elongated tank, slightly inclined in relation to the horizontal → and in which the Archimedes screw rotates. The material to be washed is brought in front of the lowest end of the tank and the washing liquid, generally water, is brought in correspondence with the highest end of said tank. The feed being continuous, the washing liquid passes over the lowest edge and entrains the impurities contained in the inert material which, transported by the screw of Archimedes, reaches the highest end whence she is discharged.

Ces installations connues à vis d'Archimède présentent le problème du lavage insuffisant de la matière inerte, surtout si très sale, dans la mesure où elle n'est lavée qu'une seule fois. Ces installations ont en outre des frais d'exploitation extrêmement élevés: en effet, elles requièrent de grandes quantités de liquide de lavage, en particulier de l'eau, chose désavantageuse en raison de la diminution toujours croissante des ressources hydriques. De plus, en raison de l'existence de l'énorme frottement, il faut une grande puissance pour que la vis d'Archimède puisse tourner et en conséquence, les palettes de celle-ci s'usent rapidement. Il faut donc remplacer fré- quemment les pièces mécaniques usées. En dernier lieu, ces installations présentent un autre problème particulièrement désavantageux consistantThese known installations with Archimedes present the problem of insufficient washing of the inert material, especially if very dirty, insofar as it is washed only once. These installations also have extremely high operating costs: in fact, they require large quantities of washing liquid, in particular water, which is disadvantageous due to the ever-increasing decrease in water resources. In addition, due to the existence of enormous friction, it takes a great deal of power for the Archimedes' screw to rotate and, as a result, its pallets wear out quickly. Worn mechanical parts must therefore be replaced frequently. Finally, these installations present another particularly disadvantageous problem consisting

en ce qu'elles nei peuvent pas laver des matières inertes de taille supérieure à 5 - 8 mm. Il existe également d'autres installations à godets, constituées par un bac semi-cylindrique contenant la matière inerte et le liquide de lavage: les godets, fixés radialement à un arbre central, y pêchent, mélangent et soulèvent la matière tout en laissant le liquide de lavage passer par les trous spécialement ménagés dans les godets et en déchargeant la matière inerte lavée dans les compartiments adjacents.in that they cannot wash inert materials larger than 5 - 8 mm. There are also other bucket installations, consisting of a semi-cylindrical tank containing the inert material and the washing liquid: the buckets, fixed radially to a central shaft, catch, mix and lift the material while leaving the liquid wash through the specially provided holes in the cups and discharging the washed inert material into the adjacent compartments.

Ces installations ont elles aussi un grand désavantage: le frottement produit et la grande puissance motrice nécessaire au fonctionnement, dans la mesure où le sable mouillé devient très compact. De plus, le lavage est lui aussi insuffisant, surtout si les matières inertes sont très sales, de même que ces installations ne peuvent produire que de petites quantités de matière lavée à la fois. En conséquence, ces installations à godets n'ont qu'un faible rendement. En dernier lieu, comme il est parfois nécessaire, ces installations ne peuvent laver que des matières inertes de taille inférieure à 5 - 8 mm.These installations also have a great disadvantage: the friction produced and the great motive power necessary for the operation, in since wet sand becomes very compact. In addition, washing is also insufficient, especially if the inert materials are very dirty, just as these installations can only produce small quantities of washed material at a time. Consequently, these bucket installations have only a low yield. Finally, as is sometimes necessary, these installations can only wash inert materials smaller than 5 - 8 mm.

La présente invention a pour but de proposer une installation de lavage de matières inertes, telles que du sable, du gravier ou des matières similaires, éliminant ou réduisant fortement ces inconvénients.The object of the present invention is to propose an installation for washing inert materials, such as sand, gravel or similar materials, eliminating or greatly reducing these drawbacks.

Nous avons atteint ce résultat, selon l'invention, en adoptant l'idée de monter plusieurs rotors tubulaires placés à distance les uns à côté des autres et fixés au même arbre, incliné ou horizontal; chaque rotor est muni de diaphragmes transversaux annulaires délimitant des canaux annulaires; chaque canal comprend plusieurs augets à sa périphérie dont le fond est muni de trous et dont la levée est inclinée par rapport à l'arbre de façon à ce que, lorsque les rotors tournent, le liquide de lavage présent dans chaque rotor déborde en dehors du diaphragme le plus bas de chaque rotor, et de façon à ce que la matière inerte à laver, introduite par la bouche du rotor situé à une extrémité de l'installation, avance à contre-courant passant par tous les rotors avant d'être déchargée par l'orifice du rotor situé à l'autre extrémité de l'installation. Les avantages obtenus grâce à cette invention consistent essentiellement en ce que l'on peut laver des matières inertes de toute taille même si très sales; en ce que la consommation de liquide de lavage et d'énergie motrice est nettement inférieure à celle des installations de type connu et ce, même par rapport à la quantité de matière lavée produite; en ce que l'installation a une durée de vie plus longue et en ce qu'elle ne re- quiert qu'une maintenance réduite.We have achieved this result, according to the invention, by adopting the idea of mounting several tubular rotors placed at a distance next to each other and fixed to the same shaft, inclined or horizontal; each rotor is provided with annular transverse diaphragms delimiting annular channels; each channel comprises several buckets at its periphery, the bottom of which is provided with holes and the lifting of which is inclined relative to the shaft so that, when the rotors rotate, the washing liquid present in each rotor overflows outside the lowest diaphragm of each rotor, and so that the inert material to be washed, introduced by the mouth of the rotor located at one end of the installation, advances against the current passing through all the rotors before being discharged through the orifice of the ro tor located at the other end of the installation. The advantages obtained thanks to this invention consist essentially in that it is possible to wash inert materials of any size even if very dirty; in that the consumption of washing liquid and motive energy is much lower than that of installations of known type, even compared to the quantity of washed material produced; in that the installation has a longer service life and in that it requires only reduced maintenance.

Dans ce qui suit, l'invention est exposée plus en détail à l'aide des dessins en annexe représentant seulement un mode d'exécution. La figure 1 est la coupe longitudinale d'un premier mode de réalisation selon l'invention; la figure 2 est la coupe longitudinale d'une deuxième forme de réalisation; la figure 3 représente l'installation des Figures 1 et 2, en vue frontale du côté de sortie de l'inerte lavée et en coupe partielle; la figure 4 est une variante de la figure 3.In the following, the invention is explained in more detail with the aid of the accompanying drawings showing only one embodiment. Figure 1 is the longitudinal section of a first embodiment according to the invention; Figure 2 is the longitudinal section of a second embodiment; 3 shows the installation of Figures 1 and 2, in front view of the outlet side of the washed inert and in partial section; FIG. 4 is a variant of FIG. 3.

Par référence à la Fig. 1 des dessins en annexe, l'installation objet de l'invention comprend essentiellement:

  • - plusieurs rotors tubulaires (1) placés à distance les uns à côté des autres et fixés au même arbre (13), horizontal ou de préférence légèrement incliné par rapport à l'horizontale; chaque rotor est muni de deux diaphragmes transversaux et annulaires (2) délimitant un canal annulaire (3). Dans chaque canal annulaire (3) sont fixés plusieurs augets (15) ayant chacun un fond (5) triangulaire et une levée (6) continue, pliée mangle par rapport au fond (5) dépassant ou non de ce canal annulaire (3). Cette paroi (6) est inclinée par rapport à l'arbre (13) des rotors (1) et se développe selon cet arbre de façon à ce que, de préférence, l'extrémité libre soit dans le canal annulaire (3) du rotor (1) adjacent situé tout en haut; la paroi (6) du rotor (1) situé à l'extrémité supérieure de l'installation dépasse en dehors de celle-ci de façon à ce que les moyens de ramassage et de transport (14) de la matière inerte lavée puissent la recueillir en fin de lavage. Du point de vue de la construction, chacune de ces parois (6) peut ne pas dépasser du rotor correspondant (1) à condition que son inclinaison par rapport à l'arbre (13) soit telle qu'elle permette à la matière inerte de s'écouler dans le canal annulaire (3) successif ou en dehors de l'installation lorsqu'elle se trouve dans le dernier rotor (1).
With reference to FIG. 1 of the accompanying drawings, the installation which is the subject of the invention essentially comprises:
  • - Several tubular rotors (1) placed at a distance next to each other and fixed to the same shaft (13), horizontal or preferably slightly inclined relative to the horizontal; each rotor is provided with two transverse and annular diaphragms (2) delimiting an annular channel (3). In each annular channel (3) are fixed several buckets (15) each having a triangular bottom (5) and a continuous lift (6), folded with the handle relative to the bottom (5) projecting or not from this annular channel (3). This wall (6) is inclined relative to the shaft (13) of the rotors (1) and develops along this shaft so that, preferably, the free end is in the annular channel (3) of the rotor (1) adjacent located at the very top; the wall (6) of the rotor (1) located at the upper end of the installation protrudes outside the latter so that the means for picking up and transporting (14) the washed inert material can collect it at the end of washing. From the construction point of view, each of these walls (6) may not protrude from the corresponding rotor (1) provided that its inclination relative to the shaft (13) is such that it allows the inert material to flow in the successive annular channel (3) or outside the installation when it is in the last rotor (1).

Conformément à la Fig. 3 des dessins en annexe, plusieurs galets (12) ont été prévus pour servir de support et faire tourner les rotors (1). - Un tuyau (7) d'alimentation en liquide lavage passe, de préférence en sens axial, dans les rotors et est muni de plusieurs bouches (8) de sortie du liquide (9) de lavage. Le mode d'exécution de la figure 1 prévoit une bouche (8) par rotor (1). - Des dispositifs d'amenée de la matière inerte sale (10) situés en face de l'extrémité inférieure de l'installation et qui sont constitués soit par un tapis transporteur (11) soit par une trémie ou similaire.According to FIG. 3 of the accompanying drawings, several rollers (12) have been provided to serve as a support and to rotate the rotors (1). - A pipe (7) for supplying washing liquid passes, preferably axially, through the rotors and is provided with several outlets (8) for outlet of the washing liquid (9). The embodiment of Figure 1 provides a mouth (8) per rotor (1). - Dirty inert material supply devices (10) located opposite the lower end of the installation and which are constituted either by a conveyor belt (11) either by a hopper or the like.

Par référence à la figure 2 des dessins en annexe, chaque rotor (1) est muni de plusieurs diaphragmes annulaires intermédiaires (2a) délimitant plusieurs canaux annulaires (3). De plus, le tuyau d'alimentation (7) en liquide de lavage présente une bouche (8) d'écoulement seulement en face du canal annulaire (3) supérieur de chaque rotor (1) alors que les canaux (3) de chaque rotor situés en dessous du premier sont remplis par l'eau débordant du canal supérieur correspondant.With reference to Figure 2 of the accompanying drawings, each rotor (1) is provided with several intermediate annular diaphragms (2a) delimiting several annular channels (3). In addition, the washing liquid supply pipe (7) has a drainage mouth (8) only opposite the upper annular channel (3) of each rotor (1) while the channels (3) of each rotor located below the first are filled with water overflowing from the corresponding upper channel.

Les figures 3 et 4 des dessins en annexe montrent l'agencement des augets (15) selon deux orientations possibles, à savoir en position radiale et inclinée par rapport au rayon du rotor (1); en tout cas, la matière inerte lavée est déchargée dans le canal annulaire (3) adjacent et situé au-dessus en raison de la rotation du rotor (1).Figures 3 and 4 of the accompanying drawings show the arrangement of the buckets (15) according to two possible orientations, namely in radial position and inclined relative to the radius of the rotor (1); in any case, the washed inert material is discharged into the adjacent annular channel (3) situated above it due to the rotation of the rotor (1).

Le fonctionnement est le suivant: la matière inerte à laver est amenée en face du ou des canaux anu- laires (3) inférieurs de l'extrémité inférieure de l'installation et le tuyau (7) d'alimentation fournit le liquide de lavage qui remplit la zone la plus basse de chaque canal (3) jusqu'au bord du diaphragme (2) inférieur d'où il s'écoule en dehors ou dans le canal (3) adjacent situé au-dessous. Après avoir débordé dans les canaux appropriés, l'eau ou le liquide de lavage apporté continuellement et en petites quantités par le tuyau (7), s'écoule vers le bas entraînant les impuretés retirées de la matière inerte. Par effet de la rotation des rotors (1), la matière inerte en cours de lavage est soulevée par les augets (15) laissant le liquide de lavage s'écouler par les trous (4); par effet de l'inclinaison des parois (6) et après une certaine élévation, la matière inerte est déchargée (dans le sens indiqué par la flèche F1 de la Fig. 1) dansThe operation is as follows: the inert material to be washed is brought in front of the lower annular channel or channels (3) of the lower end of the installation and the supply pipe (7) supplies the washing liquid which fills the lowest area of each channel (3) to the edge of the lower diaphragm (2) from where it flows outside or into the adjacent channel (3) located below. After having overflowed into the appropriate channels, the water or washing liquid supplied continuously and in small quantities through the hose (7) flows downward, entailing the impurities removed from the inert material. As a result of the rotation of the rotors (1), the inert material being washed is lifted by the buckets (15) allowing the washing liquid to flow through the holes (4); by the effect of the inclination of the walls (6) and after a certain elevation, the inert material is discharged (in the direction indicated by the arrow F1 in Fig. 1) in

le canal (3) adjacent situé au-dessus et ce, dans la mesure où cette paroi dépasse du diaphragme (2) du canal correspondant. De cette façon, après avoir été déchargée par le tapis tansporteur (11) et lavée dans le premier canal (3) inférieur, la matière inerte passe dans le deuxième canal (3) adjacent et, de canal (3) en canal (3) atteint le dernier d'où elle sera déchargée sur une goulotte (14) et ainsi retirée.the adjacent channel (3) located above, insofar as this wall protrudes from the diaphragm (2) of the corresponding channel. In this way, after being discharged by the conveyor belt (11) and washed in the first lower channel (3), the inert material passes into the second adjacent channel (3) and, from channel (3) to channel (3) reaches the last from where it will be discharged onto a chute (14) and thus withdrawn.
