Description

La présente invention concerne la récupération et le stockage de déchets provenant de machines de production, ladite récupération étant effectuée directement par collecte des déchets sur la machine. Elle concerne plus particulièrement un dispositif autonome et mobile spécialement adapté pour la collecte et le stockage de déchets provenant de matériels informatiques, déchets qui se présentent sous la forme de bandes de papier perforées, encore appelées bande Carol.The present invention relates to the recovery and storage of waste from production machines, said recovery being carried out directly by collecting waste on the machine. It relates more particularly to an autonomous and mobile device specially adapted for the collection and storage of waste from computer equipment, waste which is in the form of perforated strips of paper, also called Carol tape.

A la connaissance du demandeur, il n'existe pas de matériel spécialement conçu pour la collecte et le stockage des bandes Carol. Derrière chaque matériel informatique, générateur de telles bandes, est placé un bac de récupération dans lequel s'accumulent ces déchets. En fonctionnement normal, certaines machines informatiques peuvent générer jusqu'à 20 mètres par minute de bandes Carol. On conçoit que l'accumulation d'une telle quantité de bandes puisse poser des problèmes de stockage dans une salle informatique possédant plusieurs machines de ce type.To the knowledge of the applicant, there is no material specially designed for the collection and storage of Carol tapes. Behind each computer equipment, generating such tapes, is placed a recovery tank in which this waste accumulates. In normal operation, some computer machines can generate up to 20 meters per minute of Carol tapes. It is conceivable that the accumulation of such a quantity of tapes can pose storage problems in a computer room having several machines of this type.

Dans le domaine de la récupération de fines particules issues d'appareils de broyage, on a déjà proposé, notamment dans les documents GB 941 841 et DE 41 11 031, des dispositifs permettant de nettoyer l'air de ces fines particules. Plus particulièrement, le premier document décrit un appareil comportant un caisson, avec un compartiment de séparation, qui comporte dans sa partie inférieure une ouverture d'admission des poussières issues d'un broyeur, et qui est équipé dans sa partie supérieur d'un filtre en matériau textile. A l'extérieur du caisson, est monté un ventilateur permettant de créer par aspiration un flux d'air à l'intérieur du caisson, depuis l'ouverture d'admission, jusqu'à une ouverture d'évacuation qui est pratiquée dans la paroi supérieure du caisson. L'air aspiré à l'entrée de l'ouverture d'admission est chargé de particules de différentes tailles. Les particules les plus lourdes tombent dans le fond du caisson, avant d'atteindre le filtre ; les particules les plus fines sont véhiculées par l'air ascendant jusqu'au filtre, sur lequel elles se déposent.In the field of recovery of fine particles from grinding apparatus, devices have already been proposed, in particular in documents GB 941 841 and DE 41 11 031, for cleaning the air of these fine particles. More particularly, the first document describes an apparatus comprising a box, with a separation compartment, which comprises in its lower part an opening for admitting dust from a grinder, and which is equipped in its upper part with a filter made of textile material. On the outside of the box, a fan is mounted making it possible to create, by suction, an air flow inside the box, from the inlet opening, to a discharge opening which is made in the wall. top of the box. The air drawn in at the inlet of the intake opening is charged with particles of different sizes. The heaviest particles fall to the bottom of the box, before reaching the filter; the finest particles are carried by the ascending air to the filter, on which they deposit.

Ces dispositifs décrits dans les deux documents précités sont inaptes à effectuer la collecte de déchets volumineux, et plus particulièrement de déchets du type bandes Carol. Le même problème de collecte et de stockage se retrouve, de manière similaire, sur d'autres types de machines de production, génératrices de déchets se présentant sous forme de bandelettes continues ou discontinues ou encore de déchets solides de petite taille, par exemple des copaux d'usinage de matière plastique, par exemple du polytétrafluoréthylène plus connu sous la marque Téflon ou encore des morceaux d'aluminium se présentant sous la forme de pastille.These devices described in the two aforementioned documents are incapable of collecting bulky waste, and more particularly waste of the Carol tape type. The same problem of collection and storage is found, similarly, on other types of production machines, generating waste in the form of continuous or discontinuous strips or small solid waste, for example chips plastic material machining, for example polytetrafluoroethylene better known under the brand Teflon or aluminum pieces in the form of pellets.

Le but que s'est fixé le demandeur est de proposer un dispositif peu encombrant, qui puisse être placé à proximité d'une ou plusieurs machines de production génératrices de tels déchets et qui puisse réaliser la collecte et le stockage des déchets produits par la ou lesdites machines, sans être une gêne pour les opérateurs.The aim set by the applicant is to propose a space-saving device which can be placed close to one or more production machines generating such waste and which can collect and store the waste produced by the or said machines, without being a nuisance for operators.

Ce but est parfaitement atteint par le dispositif de l'invention qui, de manière connue, comporte un caisson, qui d'une part comprend des moyens de stockage des déchets et au moins un compartiment de séparation dont la partie inférieure est ouverte et donne sur les moyens de stockage des déchets, et qui d'autre part est équipé de moyens de ventilation et comporte une ouverture d'introduction des déchets et une ouverture d'évacuation de l'air.This object is perfectly achieved by the device of the invention which, in known manner, comprises a box, which on the one hand comprises waste storage means and at least one separation compartment whose lower part is open and overlooks the waste storage means, and which on the other hand is equipped with ventilation means and comprises a waste introduction opening and an air discharge opening.

De manière caractéristique, les moyens de ventilation consistent au moins en un premier ventilateur, qui est placé à l'intérieur du caisson, dont la bouche d'aspiration est raccordée, vers l'extérieur du caisson , à un conduit de collecte des déchets, et dont la bouche de refoulement donne dans la partie haute du compartiment de séparation, de telle sorte que le flux d'air refoulé par le premier ventilateur est projeté sensiblement horizontalement dans le compartiment de séparation ; le dispositif comprend en outre une grille de séparation de l'air et des déchets, qui est interposée entre le compartiment de séparation et l'ouverture d'évacuation du caisson, et qui est inclinée vers le bas à partir de la bouche de refoulement du premier ventilateur.Typically, the ventilation means consist at least of a first fan, which is placed inside the box, the suction mouth of which is connected, towards the outside of the box, to a waste collection duct, and the discharge mouth of which gives into the upper part of the separation compartment, so that the air flow discharged by the first fan is projected substantially horizontally into the separation compartment; the device further comprises an air and waste separation grid, which is interposed between the separation compartment and the opening evacuation of the box, and which is inclined downwards from the outlet of the first fan.

Les déchets sont captés sur la machine de production grâce au conduit de collecte, ils sont aspirés dans le conduit, passent à travers le premier ventilateur et sont projetés dans le compartiment de séparation. L'air de refoulement passe à travers la grille, et sort du dispositif par l'ouverture d'évacuation. Les déchets quant à eux, du fait de la présence de la grille, tombent vers le fond du compartiment de séparation jusqu'aux moyens de stockage. Le positionnement et l'inclinaison de la grille par rapport à la bouche de refoulement du premier ventilateur permettent aux déchets captés de glisser le long de la grille, sans risque d'accrochage ou d'accumulation.The waste is collected on the production machine through the collection duct, it is drawn into the duct, passes through the first fan and is projected into the separation compartment. The discharge air passes through the grid, and leaves the device through the exhaust opening. As for the waste, due to the presence of the grid, it falls towards the bottom of the separation compartment up to the storage means. The positioning and tilting of the grid relative to the discharge opening of the first fan allow the collected waste to slide along the grid, without risk of snagging or accumulation.

Avantageusement, s'agissant de déchets se présentant sous forme de bandes de papier continues, le premier ventilateur comporte une roue munie de couteaux, ce qui permet d'obtenir un déchiquetage des bandes continues, à l'entrée du compartiment de séparation, et par là-même de favoriser la séparation air/déchets.Advantageously, in the case of waste in the form of continuous strips of paper, the first fan comprises a wheel provided with knives, which makes it possible to obtain shredding of the continuous strips, at the entrance to the separation compartment, and by itself to promote air / waste separation.

De préférence, lorsqu'il y a un risque que s'établisse une surpression trop importante à l'intérieur du caisson, le dispositif comprend des moyens de ventilation supplémentaire qui sont raccordés à l'ouverture d'évacuation du caisson, et qui permettent une évacuation de l'air contenu dans le caisson, avec un débit suffisant pour compenser au moins en partie la surpression à l'intérieur du caisson. Ce phénomène de surpression est en effet particulièrement néfaste, lorsque le compartiment de séparation donne sur des moyens de stockage, non étanches, par exemple une presse à balles.Preferably, when there is a risk of too great an overpressure being established inside the box, the device comprises additional ventilation means which are connected to the outlet opening of the box, and which allow a evacuation of the air contained in the box, with a sufficient flow to at least partially compensate for the overpressure inside the box. This overpressure phenomenon is in fact particularly harmful, when the separation compartment opens onto non-sealed storage means, for example a baler.

Ces moyens de ventilation supplémentaire peuvent être externes au caisson, en étant raccordé à l'ouverture d'évacuation du caisson, par exemple au moyens d'un conduit souple. De préférence, afin de réaliser un dispositif autonome, ces moyens de ventilations sont intégrés au caisson. Dans ce cas, ils sont constitués par un deuxième ventilateur, qui est fixé dans le caisson au niveau de l'ouverture d'évacuation ; dans ce cas, l'ouverture d'évacuation est équipée d'un moyen de réglage du débit d'air, du type virole à registre.These additional ventilation means can be external to the box, by being connected to the outlet opening of the box, for example by means of a flexible duct. Preferably, in order to produce an autonomous device, these ventilation means are integrated into the box. In this case, they are constituted by a second fan, which is fixed in the box at the level of the evacuation opening; in this case, the discharge opening is equipped with an air flow adjustment means, of the register ferrule type.

Lorsque l'air qui est refoulé par le premier ventilateur dans le compartiment de séparation, est fortement chargé en très fines particules ou poussières, celles-ci ne sont pas interceptées par la grille de séparation. Afin de purifier cet air, après son passage à travers la grille de séparation, et avant sa sortie par l'ouverture d'évacuation, le caisson comprend avantageusement un compartiment de filtration qui est situé au dessus du compartiment de séparation, et un système de filtration, qui est placé dans le compartiment de filtration, entre la grille de séparation et l'ouverture d'évacuation du caisson.When the air which is discharged by the first fan into the separation compartment is heavily loaded with very fine particles or dust, these are not intercepted by the separation grid. In order to purify this air, after it has passed through the separation grid, and before it leaves through the discharge opening, the box advantageously comprises a filtration compartment which is located above the separation compartment, and a filtration, which is placed in the filtration compartment, between the separation grid and the evacuation opening of the box.

Selon une première variante de réalisation, le système de filtration peut consister en un filtre statique jetable. Dans ce cas, la grille de séparation est fixe.According to a first alternative embodiment, the filtration system can consist of a disposable static filter. In this case, the separation grid is fixed.

Selon une deuxième variante de réalisation, le système de filtration est constitué d'un sac dépoussiéreur qui est placé juste au-dessus du compartiment de séparation et qui est muni de moyens de vibrations ; de plus la grille est escamotable entre sa position normale et une seconde position où elle ne s'interpose plus entre les deux compartiments de séparation et de filtration. Ainsi il est possible grâce à cette disposition particulière, d'effectuer régulièrement le nettoyage du sac dépoussiéreur. Il suffit pour cela de procéder à l'escamotage de la grille et de mettre en vibration le sac dépoussiéreur de sorte que les poussières retenues sur ledit sac puissent tomber directement dans les moyens de stockage, après avoir traversé le compartiment de séparation.According to a second alternative embodiment, the filtration system consists of a dust bag which is placed just above the separation compartment and which is provided with vibration means; more the grid is retractable between its normal position and a second position where it no longer interposes between the two separation and filtration compartments. This makes it possible, thanks to this particular arrangement, to regularly clean the dust bag. It suffices for this to retract the grid and to vibrate the dust bag so that the dust retained on said bag can fall directly into the storage means, after passing through the separation compartment.

L'escamotage de la grille peut-être obtenue notamment par pivotement de celle-ci autour d'un axe horizontal, solidaire du bord de la grille qui se trouve situé vers la partie haute de la bouche de refoulement. Dans ce cas lors du pivotement, la grille se trouve placée le long d'une des faces intérieures du compartiment de séparation, jouxtant le premier ventilateur.The retraction of the grid can be obtained in particular by pivoting it around a horizontal axis, integral with the edge of the grid which is located towards the upper part of the discharge mouth. In this case during pivoting, the grid is placed along one of the interior faces of the separation compartment, adjoining the first fan.

Le sac dépoussiéreur est par exemple fixé sur un cadre support et les moyens de vibrations peuvent par exemple consister en une poignée, qui est accessible de l'extérieur du caisson et en des plots de caoutchouc sur lesquels est monté ledit cadre et aptes à subir des déplacements répétés. Lors du nettoyage du sac dépoussiéreur, il suffit à l'opérateur de se saisir de la poignée et de lui donner quelques mouvements rapides.The dust bag is for example fixed on a support frame and the vibration means can for example consist of a handle, which is accessible from outside the box and in rubber pads on which said frame is mounted and capable of undergoing repeated movements. When cleaning the dust bag, the operator just needs to grab the handle and give it a few quick movements.

Le dispositif de l'invention peut être placé sur des moyens de stockage indépendants, par exemple une benne à ciel ouvert.The device of the invention can be placed on independent storage means, for example an open skip.

Selon une première version préférée de l'invention, les moyens de stockage consistent en un réceptacle de déchets, qui se trouve dans le caisson, en-dessous du compartiment de séparation dans ce cas, le dispositif comporte des moyens d'adaptation entre la face ouverte du compartiment de séparation et l'ouverture du réceptacle. D'autre part le caisson présente une porte d'accès, en regard du réceptacle.According to a first preferred version of the invention, the storage means consist of a waste receptacle, which is located in the box, below the separation compartment in this case, the device comprises adaptation means between the face open the separation compartment and open the receptacle. On the other hand the box has an access door, facing the receptacle.

Les moyens d'adaptation consistent en une pièce prolongeant les faces intérieures du compartiment de séparation jusqu'à l'entrée du réceptacle ; bien sûr sa forme est fonction de la forme de l'ouverture du réceptacle. S'il s'agit d'un fût cylindrique, la pièce d'adaptation aura dans sa partie haute une section sensiblement carrée et dans sa partie basse une section sensiblement circulaire.The adaptation means consist of a part extending the internal faces of the separation compartment up to the entrance to the receptacle; of course its shape is a function of the shape of the opening of the receptacle. If it is a cylindrical barrel, the adapter part will have in its upper part a substantially square section and in its lower part a substantially circular section.

Le réceptacle peut également consister en un sac plastique. Dans ce le bord de l'ouverture du sac sera fixé autour de la partie basse de la pièce d'adaptation, de préférence circulaire.The receptacle can also consist of a plastic bag. In this the edge of the opening of the bag will be fixed around the lower part of the adaptation piece, preferably circular.

Selon une autre variante de réalisation, la face inférieure du compartiment de séparation donne sur les moyens de stockage par l'intermédiaire d'une vis compacteuse, logée dans la partie basse du caisson, en sorte que son ouverture d'alimentation est raccordée sur la face ouverte du compartiment de séparation, et son ouverture d'évacuation débouche sur les moyens de stockage.According to another alternative embodiment, the underside of the separation compartment gives onto the storage means by means of a compacting screw, housed in the lower part of the box, so that its feed opening is connected to the open side of the separation compartment, and its evacuation opening leads to the storage means.

De préférence l'ouverture d'évacuation de la vis compacteuse débouche en dehors du caisson par un orifice autour duquel est placé, extérieurement audit caisson, une pièce annulaire de fixation des moyens de stockage. Dans ce cas, notamment lorsque les moyens de stockage consistent en un sac plastique, il suffit à l'opérateur de positionner le sac autour de la pièce annulaire et de la fixer notamment à l'aide d'une sangle. La présence de la vis compacteuse permet de multiplier par deux ou trois le temps nécessaire au remplissage d'a même sac plastique, ce qui diminue corrélativement le temps consacré au retrait du sac rempli et à son remplacement et également l'encombrement pris pour le stockage définitif des sacs pleins.Preferably the discharge opening of the compacting screw opens out of the box through an orifice around which is placed, externally to said box, an annular piece for fixing the storage means. In this case, especially when the storage means consist of a plastic bag, it suffices the operator to position the bag around the annular part and to fix it in particular using a strap. The presence of the compacting screw makes it possible to multiply by two or three the time necessary to fill the same plastic bag, which correlatively reduces the time spent removing the filled bag and replacing it, and also the space taken up for storage. definitive full bags.

On comprend que lors de la mise en route du premier ventilateur comme de la vis compacteuse, il importe que des moyens de stockage soient présents pour recueillir les déchets. Afin d'éviter que les déchets ne tombent directement dans le fond du caisson ou bien en dehors du dispositif lorsque celui-ci comporte une vis compacteuse, il est préférable de prévoir des moyens automatiques d'arrêt du ventilateur et/ou de la vis compacteuse, en cas d'absence de moyens de stockage.It is understood that during the start-up of the first fan as of the compacting screw, it is important that storage means are present to collect the waste. In order to prevent the waste from falling directly into the bottom of the box or outside the device when the latter comprises a compacting screw, it is preferable to provide automatic means for stopping the fan and / or the compacting screw. , in the absence of storage means.

S'agissant plus particulièrement d'un sac plastique fixé sur la pièce annulaire, à l'extérieur du caisson, le dispositif comporte :

  • a) au moins un contacteur d'arrêt dont le doigt formant interrupteur, traverse ladite pièce annulaire et vient en dépassement au-dessus de celle-ci et
  • b) au moins une barrette pivotante qui est disposée au-dessus dudit doigt et de la pièce annulaire,
en sorte que lors du placement du sac autour de la pièce annulaire, celui-ci vient au-dessus de la barrette pivotante et, lors de la fixation du sac à l'aide d'un lien de fixation, telle qu'une sangle, la barrette, en pivotant sous l'action de serrement du lien, enfonce le doigt du contacteur.As it relates more particularly to a plastic bag fixed to the annular part, outside the box, the device comprises:
  • a) at least one stop switch, the finger of which forms a switch, passes through said annular part and projects above it; and
  • b) at least one pivoting bar which is arranged above said finger and the annular part,
so that when the bag is placed around the annular part, it comes above the swivel bar and, when the bag is fixed using a fixing link, such as a strap, the bar, by pivoting under the tightening action of the link, pushes the contactor's finger.

Ainsi grâce à ce système particulier d'arrêt, le ventilateur et la vis compacteuse ne peuvent être mise en route que si un sac a été placé et fixé sur la pièce annulaire, chaque doigt formant interrupteur étant alors en position de marche.Thanks to this particular stop system, the fan and the compacting screw can only be started if a bag has been placed and fixed on the annular part, each finger forming a switch then being in the on position.

Selon une autre varriante de réalisation, la face intérieure du compartiment de séparation donne sur une presse à balles qui fait également office de moyens de stockage.According to another variant, the inner face of the separation compartment opens onto a baler which also acts as storage means.

La vis compacteuse ou la presse à balles permettent de densifier les déchets, ce qui diminue d'autant la fréquence d'évacuation des produits stockés.The compacting screw or the baler makes it possible to densify the waste, which reduces the frequency of evacuation of the stored products.

Au contraire de la vis compacteuse, la presse à balles n'est pas étanche et du fait de la surpression à l'intérieur du caisson, des déchets peuvent s'échapper dans la pièce où se trouve le dispositif. Par conséquent, s'agissant d'un dispositif équipé d'une presse à balles, celui-ci sera de préférence réalisé dans sa version avec moyens de ventilation supplémentaire.Unlike the compacting screw, the baler is not waterproof and due to the overpressure inside the box, waste can escape into the room where the device is located. Consequently, in the case of a device equipped with a baler, it will preferably be made in its version with additional ventilation means.

La présente invention sera mieux comprise à la lecture de la description qui va être faite de trois exemples de réalisation d'une mini-centrale d'aspiration et de stockage de déchets illustrés par le dessin annexé dans lequel :

  • la figure 1 est une représentation schématique d'une mini-centrale avec fût de stockage incorporé,
  • la figure 2 est une représentation schématique d'une mini-centrale avec vis compacteuse,
  • la figure 3 est une vue partielle de la mini-centrale de la figure 2,
  • la figure 4 est une représentation schématique d'une mini-centrale avec presse à balles,
  • et la figure 5 est une vue de l'intérieur du caisson de la mini-central de la figure 4, au niveau du compartiment de séparation air/déchets
The present invention will be better understood on reading the description which will be given of three exemplary embodiments of a mini suction and storage central for waste illustrated by the appended drawing in which:
  • FIG. 1 is a schematic representation of a mini-power station with incorporated storage barrel,
  • FIG. 2 is a schematic representation of a mini-power plant with compactor screw,
  • FIG. 3 is a partial view of the mini-power plant in FIG. 2,
  • FIG. 4 is a schematic representation of a mini-power station with a baler,
  • and FIG. 5 is a view of the interior of the box of the mini-central of FIG. 4, at the level of the air / waste separation compartment

La mini-centrale 1 représentée à la figure 1 a l'apparence d'une armoire montée sur roulettes 2. La carcasse extérieure de cette armoire est constituée d'un caisson 3 garni intérieurement d'une couche de matériau propre à l'insonorisation 4. Dans la partie sensiblement médiane du caisson 3 se trouve logés d'une part le ventilateur 5 et d'autre part un compartiment 6 de forme sensiblement cubique, servant à la séparation de l'air de refoulement et des déchets. La bouche de refoulement 7 du ventilateur 5 est placée de telle sorte que le flux d'air refoulé soit projeté sensiblement horizontalement dans la partie haute 6a du compartiment de séparation 6.The mini-central 1 shown in FIG. 1 has the appearance of a cabinet mounted on casters 2. The outer carcass of this cabinet consists of a box 3 internally lined with a layer of material suitable for soundproofing 4 In the substantially middle part of the box 3 is housed on the one hand the fan 5 and on the other hand a compartment 6 of substantially cubic shape, used for the separation of the discharge air and the waste. The discharge opening 7 of the fan 5 is placed so that the flow of discharged air is projected substantially horizontally into the upper part 6 a of the separation compartment 6.

La bouche d'aspiration 8 du ventilateur 5 traverse le caisson 3 et est raccordée à un conduit, non représenté, destiné à la collecte des déchets. Lorsqu'il s'agit de collecter des déchets de plusieurs machines de production dans le même local, ce conduit peut être divisé en plusieurs conduits de branchement dont les extrémités libres seront placées sur lesdites machines, à la source de production des déchets.The suction mouth 8 of the fan 5 passes through the box 3 and is connected to a conduit, not shown, intended for the collection of waste. When it comes to collecting waste from several production machines in the same room, this conduit can be divided into several connection conduits, the free ends of which will be placed on said machines, at the source of production of the waste.

De préférence, de manière à insonoriser au mieux la mini-centrale, la bouche d'aspiration 8 du ventilateur 5 est prolongée par un demi-silencieux affleurant le caisson et le conduit de collecte est lui-même terminé par un demisilencieux apte à être emboîté dans celui monté à demeure sur le caisson.Preferably, so as to soundproof the mini-central as well as possible, the suction mouth 8 of the fan 5 is extended by a half-silencer flush with the box and the collection duct is itself terminated by a half-silencer capable of being fitted in the one permanently mounted on the box.

Une grille 9 de séparation occupe toute la section du compartiment 6 de séparation. Cette grille 9 est fixée par l'un de ses bords à un axe horizontal 10, luimême fixé le long de la partie supérieure 7a de la bouche de refoulement 7 du ventilateur 5. La grille 9 est pivotante autour de l'axe 10, son bord 11, opposé audit axe 10, étant en position normale, appliquée contre une butée 12, qui est en dessous du niveau de l'axe 10 de manière à ce que ladite grille fasse, par rapport à l'horizontal, un angle α d'environ 20°.A separation grid 9 occupies the entire section of the separation compartment 6. This grid 9 is fixed by one of its edges to a horizontal axis 10, itself fixed along the upper part 7 a of the discharge mouth 7 of the fan 5. The grid 9 is pivotable around the axis 10, its edge 11, opposite said axis 10, being in the normal position, applied against a stop 12, which is below the level of axis 10 so that said grid makes, with respect to the horizontal, an angle α about 20 °.

La butée 12 est une butée supérieure c'est-à-dire que lors de son pivotement autour de l'axe 10 la grille 9 descend jusqu'à sensiblement prendre une position verticale, à l'intérieur du compartiment de séparation 6.The stop 12 is an upper stop, that is to say that during its pivoting around the axis 10 the grid 9 descends until substantially taking a vertical position, inside the separation compartment 6.

Le maintien de la grille 9 contre la butée 12, en position normale est obtenu par exemple à l'aide d'a système à ressort monté autour de l'axe 10 et repoussant la grille 9 vers le haut.Maintaining the grid 9 against the stop 12 in the normal position is obtained for example using a spring system mounted around the axis 10 and pushing the grid 9 upwards.

Le pivotement de la grille 9 vers le bas peut être commandé de l'extérieur du caisson grâce à un volant de commande monté sur l'arbre 10.The pivoting of the grid 9 downwards can be controlled from outside the box using a control wheel mounted on the shaft 10.

Le compartiment 6 de séparation a sa face supérieure qui est ouverte et donne dans le compartiment de filtration 13. Ce compartiment comporte le système de filtration proprement dit 14 ainsi qu'une ouverture 15 d'évacuation de l'air, pratiquée dans le caisson 3.The separation compartment 6 has its upper face which is open and gives into the filtration compartment 13. This compartment comprises the filtration system proper 14 as well as an air discharge opening 15, formed in the box 3 .

Le système de filtration 14 consiste en un sac dépoussiéreur 16, en toile, qui est accroché et suspendu sur un cadre métallique avec des traverses horizontales 18 entre lesquelles le sac 16 pend sous forme de boucles, lesdites boucles étant maintenues en position grâce à des inserts non représentés. Le sac dépoussiéreur 16, dans la partie basse des boucles, occupe toute la section de passage entre le compartiment de séparation 6 et le compartiment de filtration 13.The filtration system 14 consists of a dust bag 16, made of canvas, which is hung and suspended on a metal frame with horizontal crosspieces 18 between which the bag 16 hangs in the form of loops, said loops being held in position by means of inserts not shown. The dust bag 16, in the lower part of the loops, occupies the entire passage section between the separation compartment 6 and the filtration compartment 13.

Il est à noter que le système de filtration 14 peut également être un filtre cassette jetable ; dans ce cas la grille 9 n'a pas besoin d'être montée pivotante.It should be noted that the filtration system 14 can also be a disposable cassette filter; in this case the grid 9 does not need to be pivotally mounted.

Le cadre métallique 17 est monté souple sur deux joints de caoutchouc 19 du type Paulstra. Il est également muni d'une poignée 20 passant à travers le caisson 3.The metal frame 17 is mounted flexible on two rubber seals 19 of the Paulstra type. It is also provided with a handle 20 passing through the box 3.

La partie inférieure du compartiment 6 de séparation est prolongée par une pièce d'adaptation permettant de transformer la section sensiblement carrée du compartiment de séparation 6 en une section sensiblement circulaire. L'extrémité inférieure 21a de cette pièce d'adaptation 21 a un diamètre qui est déterminé en fonction du moyen de stockage mis en oeuvre.The lower part of the separation compartment 6 is extended by an adaptation piece making it possible to transform the substantially square section of the separation compartment 6 into a substantially circular section. The lower end 21 a of this adaptation piece 21 has a diameter which is determined as a function of the storage means used.

Dans l'exemple représenté sur la figure 1 il s'agit d'un fût 22 qui est placé à l'intérieur du caisson 3, sous ladite extrémité 21a. Bien sûr dans ce cas le caisson est pourvu d'une porte d'accès non représentée, permettant l'introduction et l'évacuation du fût de stockage 22.In the example shown in Figure 1 it is a barrel 22 which is placed inside the box 3, under said end 21 a . Of course in this case the box is provided with an access door, not shown, allowing the introduction and evacuation of the storage barrel 22.

Le fonctionnement de la mini-centrale 1 est le suivant : le ou les conduits de collecte, dont les extrémités libres sont placées directement sur les machines de production, véhiculent les déchets, par aspiration, grâce à l'action du ventilateur 5. Ces déchets et l'air aspiré sont refoulés ensemble à travers la bouche de refoulement 7. La présence de la grille 9 permet de réaliser la séparation de l'air refoulé qui préférentiellement passe à travers les trous de la grille et remonte vers le compartiment de filtration 13 tandis que les déchets sont retenus par la grille et sont dirigés vers le fût 22. Le positionnement et l'inclinaison de la grille 9 sont déterminés en vue de favoriser la formation d'un film d'air sur sa surface, ce qui permet aux déchets de glisser le long de celle-ci, sans risque d'accrochage ou d'accumulation. De plus la grille 9 est choisie avec une section ouverte qui crée une vitesse ascensionnelle de l'air, telle que cette vitesse soit insuffisante pour provoquer une remontée éventuelle des déchets depuis le fût 22.The operation of the mini-power plant 1 is as follows: the collection pipe or pipes, the free ends of which are placed directly on the production machines, convey the waste, by suction, thanks to the action of the fan 5. This waste and the sucked air are discharged together through the discharge mouth 7. The presence of the grid 9 makes it possible to separate the discharged air which preferably passes through the holes in the grid and goes up towards the filtration compartment 13 while the waste is retained by the grid and is directed towards the barrel 22. The positioning and the inclination of the grid 9 are determined in order to promote the formation of an air film on its surface, which allows the waste to slide along it, without risk of snagging or accumulation. In addition, the grid 9 is chosen with an open section which creates a rising speed of the air, such that this speed is insufficient to cause a possible rise of the waste from the barrel 22.

A titre d'exemple non limitatif, le ventilateur mis en oeuvre avait un débit de l'ordre de 1 200 m³/heure pour une pression de 200 millimètres de hauteur d'eau. La grille avait une maille de 2 x 2 millimètres.By way of nonlimiting example, the fan used had a flow rate of the order of 1,200 m³ / hour for a pressure of 200 millimeters of water height. The grid had a mesh of 2 x 2 millimeters.

S'agissant de déchets se présentant sous la forme de bandes de papier perforées, du type bande Carol, le ventilateur mis en oeuvre comportait une roue munie de couteaux ce qui permettait d'obtenir un certain déchiquetage des bandes continues, favorable à la séparation air/déchets.In the case of waste in the form of perforated strips of paper, of the Carol strip type, the fan used included a wheel provided with knives, which made it possible to obtain a certain shredding of the continuous strips, favorable for air separation. /waste.

L' air refoulé passant à travers la grille 9 traverse le sac dépoussiéreur 16, permettant la retenue des particules fines contenues dans cet air. L'air ainsi filtré est réintroduit dans le local en passant par l'ouverture d'évacuation 15.The discharged air passing through the grid 9 passes through the dust bag 16, allowing the retention of fine particles contained in this air. The air thus filtered is reintroduced into the room through the exhaust opening 15.

Régulièrement l'opérateur peut effectuer le nettoyage du sac dépoussiéreur 16. Il lui suffit dans un premier temps de commander en pivotement la grille 9 jusqu'à ce que celle-ci vienne verticalement et laisse libre le passage entre le compartiment de séparation 6 et le compartiment de filtration 13. Il lui suffit ensuite de saisir la poignée 20 et de lui faire subir des mouvements répétés. Ces mouvements entraînent le cadre 17, solidaire de la poignée 20, en vibration sur les joints de caoutchouc 19. Ceci a pour effet de secouer le sac 16 et de faire tomber les particules fines qui se sont accumulées sur les parois des boucles du sac 16.Regularly the operator can carry out the cleaning of the dust bag 16. It is sufficient for him at first to pivotally control the grid 9 until it comes vertically and leaves free passage between the separation compartment 6 and the filtration compartment 13. It then suffices to grasp the handle 20 and subject it to repeated movements. These movements cause the frame 17, integral with the handle 20, to vibrate on the rubber seals 19. This has the effect of shaking the bag 16 and causing the fine particles which have accumulated on the walls of the loops of the bag 16 to fall. .

Les particules fines qui s'étaient accumulées sur le sac 16 tombent alors directement dans le fût 22, parmi les déchets.The fine particles which had accumulated on the bag 16 then fall directly into the barrel 22, among the waste.

Dans le second exemple de réalisation illustré à la figure 2, la partie de la mini-centrale 23 qui est située au-dessus de l'axe AA' est strictement identique à ce qui a été décrit précédemment dans le premier exemple.In the second exemplary embodiment illustrated in FIG. 2, the part of the mini-power station 23 which is located above the axis AA ′ is strictly identical to what was described previously in the first example.

Cette mini-centrale 23 se caractérise principalement par la présence d'une vis compacteuse 24 qui permet de densifier les déchets récupérés avant leur introduction dans les moyens de stockage.This mini-central 23 is mainly characterized by the presence of a compacting screw 24 which makes it possible to densify the waste recovered before its introduction into the storage means.

La vis compacteuse 24 se présente sous la forme d'une vis sans fin 25 montée à l'intérieure d'une enceinte cylindrique 26 de diamètre intérieur légèrement plus important que le diamètre de la vis 25.The compacting screw 24 is in the form of an endless screw 25 mounted inside a cylindrical enclosure 26 with an inside diameter slightly larger than the diameter of the screw 25.

Cette vis sans fin 25 est entraînée grâce à un moto-réducteur non représenté.This worm 25 is driven by a not shown gear motor.

La vis compacteuse 24 est placée dans la partie basse du caisson 3. Son ouverture d'alimentation 27 est raccordée au compartiment de séparation 6 grâce à une pièce de transformation 28 qui permet d'amener tous les déchets provenant du compartiment de séparation 6 dans l'ouverture d'alimentation 27. Afin d'éviter l'accumulation de déchets dans la partie 30, la plus avant de la vis compacteuse 24, de préférence la face 29 de la pièce d'adaptation 28, qui se trouve dans le prolongement de la butée 12, a une inclinaison vers l'arrière comme cela est représenté à la figure 2.The compacting screw 24 is placed in the lower part of the box 3. Its feed opening 27 is connected to the separation compartment 6 by means of a transformation part 28 which makes it possible to bring all the waste coming from the separation compartment 6 into the feed opening 27. In order to avoid the accumulation of waste in the part 30, the foremost of the compacting screw 24, preferably the face 29 of the adaptation piece 28, which is in the extension of the stop 12 has a backward inclination as shown in FIG. 2.

L'extrémité arrière 31 de l'enceinte 26 de la vis compacteuse 24 passe à travers le caisson 3. Cette extrémité 31 est entourée, le long du caisson 3 d'une pièce annulaire 32 de fixation du moyen de stockage qui en l'occurrence se présente sous la forme d'un sac plastique 33. Celui-ci est placé autour de la pièce annulaire 32 et fixé sur celle-ci grâce à un lien 34, par exemple une sangle.The rear end 31 of the enclosure 26 of the compacting screw 24 passes through the box 3. This end 31 is surrounded, along the box 3 of an annular piece 32 for fixing the storage means which in this case is in the form of a plastic bag 33. The latter is placed around the annular part 32 and fixed thereon by means of a link 34, for example a strap.

Le fonctionnement de la mini-centrale 23 est identique à ce qui a été décrit précédemment dans le premier exemple jusqu'à l'introduction des déchets dans la pièce d'adaptation 28.The operation of the mini-central 23 is identical to what was described previously in the first example until the introduction of the waste into the adaptation part 28.

Les déchets tombent par l'ouverture d'alimentation 27 à l'intérieur de la vis compacteuse 28. Sous l'action de la vis sans fin 25 lesdits déchets sont entraînés et compactés jusqu'à l'extrémité 31 de l'enceinte 26. Ils sont introduits dans le sac plastique 33 pour y être stockés.The waste falls through the feed opening 27 inside the compacting screw 28. Under the action of the worm 25 said waste is entrained and compacted up to the end 31 of the enclosure 26. They are introduced into the plastic bag 33 to be stored there.

On remarque qu'il s'établit une certaine surpression à l'intérieur du caisson jusque dans le sac plastique 33 en sorte que celui-ci, s'il est imperméable à l'air, reste constamment à l'état gonflé.It is noted that a certain overpressure is established inside the box as far as the plastic bag 33 so that the latter, if it is impermeable to air, remains constantly in the inflated state.

La vis compacteuse utilisée avait dans un exemple précis de réalisation non limitatif un diamètre de 300 millimètres avec un pas de 300 millimètres, tandis que l'enceinte 26 avait a diamètre de 350 millimètres. La rotation de la vis sans fin 25 était de l'ordre de 30 tours/minute.The compacting screw used had in a specific embodiment not limiting a diameter of 300 millimeters with a pitch of 300 millimeters, while the enclosure 26 had a diameter of 350 millimeters. The rotation of the worm 25 was of the order of 30 revolutions / minute.

Afin d'optimiser le fonctionnement de la mini-centrale 23, le moto réducteur, entraînant en rotation la vis sans fin 25, était mai d'un détecteur d'intensité permettant, en cas de variation de ladite intensité, de déclencher une alarme sonore ou visuelle. On comprend que cette variation d'intensité est provoquée par l'accumulation des déchets à l'intérieur de la vis compacteuse, lorsque le sac 33 de stockage est plein.In order to optimize the operation of the mini-central 23, the reduction motor, driving the worm 25 in rotation, may have been an intensity detector making it possible, in the event of variation of said intensity, to trigger an audible alarm or visual. It is understood that this variation in intensity is caused by the accumulation of waste inside the compacting screw, when the storage bag 33 is full.

Le fait que le sac 33 se trouve fixé sur la pièce annulaire 32 près du caisson 3 alors que l'extrémité arrière 31 se trouve largement à l'intérieur du sac, permet d'éviter que les déchets se déversent sur le sol lorsque l'on enlève le lien 34 et que l'on ferme le sac 33.The fact that the bag 33 is located on the annular part 32 near the box 3 while the rear end 31 is largely inside the bag, prevents waste from spilling onto the ground when the remove the link 34 and close the bag 33.

De plus comme cela ressort de la figure 3 on a monté sur la pièce annulaire 32 un contacteur 35 qui est placé entre ladite pièce annulaire 32 et l'extrémité 31 de l'enceinte 26, extérieurement au caisson 3. Ce contacteur 35 comporte un doigt 36 qui fait office d'interrupteur et qui passe par un évidement 37 prévu dans la pièce annulaire 32. En position normale l'extrémité du doigt 36 dépasse de la pièce 32. De plus une barrette 38 est montée pivotante par l'un de ses bords 39 qui est fixée à a axe de pivotement 40 situé au niveau de la pièce annulaire 32 à proximité du caisson 3. Cette barrette 38, en position normale, vient s'appliquer sur le doigt 36 qui dépasse de la pièce annulaire 32. Dans ce cas le contacteur 35 commande l'arrêt du ventilateur 5 et de la vis compacteuse 24.In addition, as can be seen from FIG. 3, a contactor 35 is mounted on the annular part 32 which is placed between said annular part 32 and the end 31 of the enclosure 26, outside the casing 3. This contactor 35 has a finger 36 which acts as a switch and which passes through a recess 37 provided in the annular part 32. In normal position the end of the finger 36 protrudes from the part 32. In addition, a bar 38 is pivotally mounted by one of its edges 39 which is fixed to a pivot axis 40 located at the level of the annular part 32 near the casing 3. This bar 38, in normal position, is applied to the finger 36 which protrudes from the annular part 32. In in this case, the contactor 35 controls the stopping of the fan 5 and of the compacting screw 24.

Lors du placement du sac 33 sur la pièce annulaire 32, ledit sac 33 est placé de telle sorte qu'il recouvre la barrette 38. Sa fixation est réalisée grâce à la sangle 34 qui exerce, grâce à son élasticité, une force de compression sur le sac 33 et corrélativement sur la barrette 38. Ceci provoque un pivotement de ladite barrette 38 autour de l'axe 40. Ce pivotement entraîne l'enfoncement du doigt 36, ce qui actionne le contacteur 35 en sorte qu'il devient alors possible de mettre en route le ventilateur 5 et la vis compacteuse 24.When placing the bag 33 on the annular part 32, said bag 33 is placed so that it covers the bar 38. Its fixing is carried out by means of the strap 34 which exerts, due to its elasticity, a compressive force on the bag 33 and correspondingly on the bar 38. This causes said bar 38 to pivot around the axis 40. This pivoting causes the finger 36 to be pushed in, which actuates the contactor 35 so that it then becomes possible to bring into the fan 5 and the compactor screw 24.

Par mesure de sécurité, il est préférable de prévoir sur la pièce annulaire 32, deux contacteurs 35, coopérant chacun avec une barette 38.For safety reasons, it is preferable to provide two contactors 35 on the annular part 32, each cooperating with a bar 38.

Le caisson 3 était dans les deux exemples précités monté sur quatre roulettes dont deux étaient pivotantes pour faciliter la manutention à l'intérieur des locaux. Dans les deux exemples, les dimensions de la mini-centrale étaient calculées en sorte que celle-ci puisse passer par une porte traditionnelle.The box 3 was in the two aforementioned examples mounted on four casters, two of which were swivel to facilitate handling inside the premises. In the two examples, the dimensions of the mini-power plant were calculated so that it could pass through a traditional door.

Dans le troisième exemple de réalisation illustré à la figure 4, la partie inférieure de la mini-centrale 41 qui est située au-dessous de l'axe BB' se différencie de la partie de la mini-centrale 23 située au dessous de l'axe AA', principalement en ce que la vis compacteuse 24 a été remplacée par une presse à balles, ce qui permet d'obtenir un compactage plus important des déchets, et en ce que le caisson 3 n'est pas monté sur roues, mais repose au sol par l'intermédiaire de quatre poutres verticales 42, dont seulement deux d'entre elles sont visibles sur la figure 4. La presse à balles étant par ailleurs bien connue, la description de cette partie inférieure de la mini centrale 42 ne sera donc pas répétée.In the third exemplary embodiment illustrated in FIG. 4, the lower part of the mini-central 41 which is located below the axis BB 'differs from the part of the mini-central 23 located below the axis AA ', mainly in that the compacting screw 24 has been replaced by a baler, which makes it possible to obtain greater compaction of the waste, and in that the box 3 is not mounted on wheels, but rests on the ground by means of four vertical beams 42, of which only two of them are visible in FIG. 4. Since the baler is also well known, the description of this lower part of the mini central 42 will not be therefore not repeated.

L'intérieur de la partie supérieure 43 du caisson 3, qui est située au-dessus de l'axe BB' et, qui est caractéristique de la mini-centrale 41, est illustré à la figure 5. Par soucis de clarté, les éléments de cette partie supérieure 43, qui se retrouvent dans la partie du caisson 3 de la mini centrale 23, qui est située au-dessus de l'axe AA', ont été indiqués avec les mêmes références. La partie supérieure 43 du caisson 3 de la mini centrale 41 présente la particularité de ne pas comprendre de compartiment de filtration, mais de comporter a unique compartiment de séparation 6, qui communique avec l'ouverture d'évacuation 15 de l'air, par l'intermédiaire d'un ventilateur hélicoïdal 44, fixé à l'intérieur du caisson 3, au niveau de l'ouverture d'évacuation 15. En outre, le caisson ne comportant pas de système de filtration intégré au caisson 3, la grille 9 qui est interposée entre le compartiment de séparation 6 et l'ouverture d'évacuation 15 est fixe, et n'est pas monté pivotante.The interior of the upper part 43 of the box 3, which is located above the axis BB 'and, which is characteristic of the mini-central 41, is illustrated in FIG. 5. For the sake of clarity, the elements of this upper part 43, which are found in the part of the box 3 of the mini central 23, which is located above the axis AA ', have been indicated with the same references. The upper part 43 of the box 3 of the mini power plant 41 has the particularity of not comprising a filtration compartment, but of having a single separation compartment 6, which communicates with the air discharge opening 15, by through a helical fan 44, fixed inside the box 3, at the discharge opening 15. In addition, the box not having a filtration system integrated into the box 3, the grid 9 which is interposed between the separation compartment 6 and the discharge opening 15 is fixed, and is not pivotally mounted.

Lorsque la presse à balles est en marche, et en l'absence de moyens de ventilation supplémentaire, il s'établit une surpression à l'intérieur du caisson, qui est par exemple de l'ordre de 15 à 20 mm de colonne d'eau. Etant donné que la presse à balles n'est pas étanche, cela occasionne des projections de déchets dans la pièce où se trouve le dispositif, ce qui est préjudiciable au bon fonctionnement de la mini-centrale. Le ventilateur 44 a pour fonction de provoquer une évacuation forcée de l'air à travers l'ouverture d'évacuation 15, afin de s'opposer à ce phénomène de surpression. Le débit d'évacuation d'air est prévu pour que ne subsiste qu'une faible surpression à l'intérieur du caisson 3 par exemple de l'ordre de 5 mm de colonne d'eau, qui est suffisante pour permettre l'évacuation naturelle des déchets vers la presse à balles mais insuffisante pour obtenir des projections des déchets dans la pièce. Afin de permettre un réglage de ce débit d'évacuation de l'air, et donc de la légère supression résiduelle, l'ouverture 15 est équipée d'une virole à registre 45, qui permet à un utilisateur de la mini-centrale 41, de régler manuellement la section de l'ouverture d'évacuation 15.When the baler is in operation, and in the absence of additional ventilation means, there is an overpressure inside the box, which is for example of the order of 15 to 20 mm of column water. Since the baler is not waterproof, this causes waste to be projected into the room where the device is located, which is detrimental to the proper functioning of the mini-power plant. The fan 44 has the function of causing a forced evacuation of the air through the evacuation opening 15, in order to oppose this overpressure phenomenon. The air evacuation flow is provided so that only a slight overpressure remains inside the casing 3, for example of the order of 5 mm of water column, which is sufficient to allow natural evacuation waste to the baler but insufficient to obtain projections of waste in the room. In order to allow adjustment of this air evacuation flow rate, and therefore of the slight residual suppression, the opening 15 is equipped with a register ferrule 45, which allows a user of the mini-central 41, manually adjust the section of the discharge opening 15.

Dans un exemple précis de réalisation, le ventilateur 5 mis en oeuvre avait un débit de l'ordre de 2 700 m³/h pour une pression de 300 mm de hauteur d'eau et le ventilateur 44, un débit de l'ordre de 3 000 m³/h pour une pression de 15 mm de hauteur d'eau.In a specific embodiment, the fan 5 used had a flow rate of the order of 2,700 m³ / h for a pressure of 300 mm of water height and the fan 44, a flow rate of the order of 3 000 m³ / h for a pressure of 15 mm of water height.

Il est possible, dans le cadre de l'invention, de remplacer le ventilateur 45, par tous moyens de ventilation placés à l'extérieur du caisson 3, et raccordés à l'ouverture d'évacuation. De même, on pourrait équiper la mini-centrale 41 avec un système de filtration, placé à l'extérieur du caisson 3, et raccordé à l'ouverture d'évacuation de celui-ci, au moyen par exemple d'un conduit souple ou d'une canalisation, sur laquelle peuvent être prévus des volets de réglage de la surpression, comparables à la virole à registre 45. Un tel système de filtration externe pourrait également remplacer le système de filtration 14, qui est intégré au caisson 3 des mini-centrales 1 et 23.It is possible, in the context of the invention, to replace the fan 45, by any ventilation means placed outside the box 3, and connected to the discharge opening. Similarly, one could equip the mini-central 41 with a filtration system, placed outside the box 3, and connected to the discharge opening thereof, for example by means of a flexible conduit or a pipe, on which overpressure adjustment flaps can be provided, comparable to the register shell 45. Such an external filtration system could also replace the filtration system 14, which is integrated into the box 3 of the mini panels 1 and 23.

Les mêmes mini-centrales qui ont été décrites ont été mises en oeuvre avec d'autres types de déchets que les bandes Carol, en particulier avec des bandelettes de polytétrafluoréthylène, provenant de l'usinage de pièces plastiques et également avec des pastilles d'aluminium collectées sur des machines de production.The same mini-plants which have been described have been implemented with other types of waste than Carol tapes, in particular with polytetrafluoroethylene strips, coming from the machining of plastic parts and also with aluminum pellets collected on production machines.
