Description

Dispositif autonome pour aspirer les déchets et broyer les plus légers Autonomous device for vacuuming waste and grinding the lightest
La présente invention a pour objet un dispositif autonome pour aspirer les déchets et broyer les plus légers. Le secteur technique de l ' invention est le domaine de la construction d'appareils de nettoyage et de leur utilisation par des procédés utilisant un courant d'air d'aspiration.The present invention relates to an autonomous device for sucking up waste and grinding the lightest. The technical field of the invention is the field of the construction of cleaning apparatuses and their use by methods using a draft of suction air.
L' application principale de l'invention est le ramassage de déchets de toute nature sur la voie publique, donc à l'extérieur et sans source d'alimentation d'énergie externe.The main application of the invention is the collection of waste of all kinds on public roads, therefore outside and without external power supply source.
A ce jour, ce ramassage se fait en effet avec des dispositifs d'aspiration lourds et difficilement maniables, sans parler des véhicules de nettoyage proprement dits qui sont hors du cadre de la présente invention. On peut citer par exemple le brevet FR 2.671.746 de la Société dite KIORITZ CORPORATION, intitulé « Aspirateur de déchets pour utilisation extérieure » : ce document décrit un aspirateur comprenant un chariot sur lequel est placé un récipient comportant une ouverture vers le haut, avec un bloc d'aspiration monté sur ledit chariot et un couvercle également solidaire dudit chariot et monté pivotant pour pouvoir s' ouvrir et se fermer par rotation au-dessus de l 'ouverture dudit récipient ; une extrémité d'un premier tuyau dit de vide est reliée audit couvercle, et l ' autre extrémité à un orifice d'aspiration du bloc d'aspiration ; un autre tuyau muni d'un orifice d'entrée d'aspiration libre à son extrémité extérieure, est également relié audit couvercle ; la caractéristique d'un tel aspirateur suivant ce brevet antérieur est le fait que, d'une part le couvercle est conçu de manière à faire saillie par rapport au conteneur, du côté du bloc d'aspiration du chariot, lorsque le couvercle est fermé sur l'ouverture du conteneur, et que d'autre part l'extrémité du tuyau de vide est reliée au fond de ladite partie en saillie du couvercle, de façon que l'axe de rotation de celui-ci passe par le voisinage du centre de cette extrémité. Un tel dispositif d 'aspiration est assez lourd et complexe , représentant une masse de plus de 80 kilos que l ' opérateur doit donc déplacer en tractant ou en poussant ledit chariot pour l 'amener aux endroits où il doit aspirer les déchets ; de plus, un tel dispositif qui fonctionne comme un aspirateur classique, se remplit très rapidement lorsqu'on aspire des déchets volumineux, et si ceux-ci sont légers, ils viennent obstruer l 'orifice du tuyau dit à vide, relié au bloc d' aspiration, arrêtant ainsi toute possibilité de continuer le nettoyage, après de l 'ordre de 30 secondes d'utilisation, ce qui est très court et peu efficace.To date, this collection is in fact done with heavy suction devices which are difficult to handle, not to mention the actual cleaning vehicles which are outside the scope of the present invention. Mention may be made, for example, of patent FR 2,671,746 of the company known as KIORITZ CORPORATION, entitled “Waste vacuum cleaner for outdoor use”: this document describes a vacuum cleaner comprising a cart on which is placed a container having an opening upwards, with a suction unit mounted on said carriage and a cover also integral with said carriage and pivotally mounted to be able to open and close by rotation above the opening of said container; one end of a first so-called vacuum pipe is connected to said cover, and the other end to a suction port of the suction block; another pipe provided with a free suction inlet orifice at its outer end, is also connected to said cover; the characteristic of such a vacuum cleaner according to this prior patent is the fact that, on the one hand, the cover is designed so as to protrude relative to the container, on the side of the suction unit of the carriage, when the cover is closed on the opening of the container, and that on the other hand the end of the vacuum pipe is connected to the bottom of said protruding part of the cover, so that the axis of rotation of the latter passes through the vicinity of the center of this end. Such a suction device is quite heavy and complex, representing a mass of more than 80 kilos that the operator must therefore move by pulling or pushing said carriage to bring it to the places where it must vacuum the waste; moreover, such a device which functions like a conventional vacuum cleaner, fills up very quickly when aspirating bulky waste, and if these are light, they come to obstruct the orifice of the said vacuum hose, connected to the block of suction, thus stopping any possibility of continuing cleaning, after about 30 seconds of use, which is very short and ineffective.
On connaît également divers aspirateurs de type classique, donc plus légers que le dispositif précédent, et capables d' aspirer également tout type de déchet mais qui ne peuvent être utilisés que dans des locaux fermés ou éventuellement autour de ceux-ci car ils nécessitent une alimentation électrique extérieure, ce qui en limite le rayon d' action ; de toute façon, leur mode de fonctionnement est du même type que le précédent, avec une aspiration de l 'ensemble des déchets dans un conteneur, du reste spécifique et qui se remplit très rapidement et dont les déchets légers viennent obstruer le filt re séparant ledit conteneur de la turbine d'aspiration.Various conventional vacuum cleaners are also known, therefore lighter than the previous device, and capable of also vacuuming any type of waste but which can only be used in closed rooms or possibly around them because they require a power supply. electric outdoor, which limits the radius of action; in any case, their mode of operation is of the same type as the previous one, with an aspiration of all the waste in a container, of the specific remainder and which fills very quickly and whose light waste comes to obstruct the filter separating said container of the suction turbine.
Par ailleurs, il existe aussi des engins légers , utilisables sur la voie publique, conçus pour aspirer et broyer des feuilles mortes , afin d' en réduire le volume, mais ils ne peuvent alors pas absorber les déchets lourds qui pourraient être mélangés auxdites feuilles mortes j onchant le sol , sous peine d'endommager gravement le système de broyage. De plus, comme les aspirateurs dits classiques, ils sont associés à des conteneurs spécifiques.In addition, there are also light machines, usable on public roads, designed to suck and crush dead leaves, in order to reduce the volume, but they cannot then absorb the heavy waste which could be mixed with said dead leaves. on the ground, otherwise the grinding system will be seriously damaged. In addition, like the so-called conventional vacuum cleaners, they are associated with specific containers.
Le problème posé est en effet de pouvoir réaliser et utiliser un dispositif autonome pour aspirer tous les déchets que l ' on peut rencontrer sur la voie publique, en utilisant des conteneurs, de préférence de type standard et que l' on veut pouvoir remplir au maximum desdits déchets, sans qu'ils soient trop rapidement obstrués par les déchets volumineux et légers, tout en proposant un dispositif simple, léger, facilement déplaçable par un opérateur, d'une grande autonomie et sans risque d ' endommager le dispositif , d' aspiration, tout en étant d'un prix de revient raisonnable, permettant ainsi à toute collectivité de s 'en équiper d 'un grand nombre . La présente invention permet d'atteindre tous ces objectifs grâce à un dispositif pour aspirer tout type de déchet dans un conteneur standard en sélectionnant physiquement les déchets légers de faible densité pour les broyer, et en les éjectant dans un sac de ramassage, alors que les déchets lourds tombent par inertie dans le conteneur. Une solution au problème posé est en effet un dispositif autonome pour aspirer les déchets, comprenant un capot apte à constituer un couvercle pour recouvrir et fermer l 'ouverture d 'un conteneur à déchets , un bloc d ' aspiration apte à créer une dépression dans ledit conteneur par une ouverture d' aspiration débouchant dans ledit capot et un conduit d' aspiration dont une extrémité est mobile pour être déplacée en tout point où l ' on veut aspirer un déchet et l ' autre extrémité est reliée audit capot à travers lequel elle débouche ; selon l ' invention, le bloc d 'aspiration est directement monté sur ledit capot avec son orifice d ' entrée constituant ladite ouverture d'aspiration dans celui-ci, lequel bloc d' aspiration est apte à broyer les déchets légers, et son orifice de refoulement est relié à un récipient de collecte desdits déchets broyés, ledit conteneur constituant le réceptacle des déchets lourds ; ledit récipient de collecte de déchets broyés est de préférence un sac, dont une partie au moins de l 'enveloppe est poreuse pour laisser passer l'air sous pression qui est soufflé par ledit bloc d'aspiration et retenir lesdits déchets broyés, lequel sac est monté suspendu latéralement audit capot. De préférence, ledit conteneur est un conteneur standard pour déchets, équipé de roues.The problem posed is in fact to be able to produce and use an autonomous device for sucking up all the waste that can be encountered on public roads, using containers, preferably of the standard type and that we want to be able to fill to the maximum. said waste, without being too quickly obstructed by bulky and light waste, while proposing a device simple, light, easily movable by an operator, of a great autonomy and without risk of damaging the device , of aspiration, while being of a reasonable cost price, thus allowing any community to be equipped with 'a big number . The present invention makes it possible to achieve all of these objectives by means of a device for sucking up any type of waste in a standard container by physically selecting light low density waste for grinding it, and ejecting it in a collection bag, while the heavy waste inertially falls into the container. A solution to the problem posed is in fact an autonomous device for sucking up the waste, comprising a cover capable of constituting a cover for covering and closing the opening of a waste container, a suction block able to create a vacuum in said container by a suction opening opening into said cover and a suction pipe, one end of which is movable so as to be moved to any point where it is desired to suck up a waste and the other end is connected to said cover through which it opens ; according to the invention, the suction block is directly mounted on said cover with its inlet orifice constituting said suction opening therein, which suction block is capable of grinding light waste, and its orifice delivery is connected to a container for collecting said crushed waste, said container constituting the receptacle for heavy waste; said container for collecting crushed waste is preferably a bag, at least part of the envelope of which is porous to let the pressurized air pass through which is blown by said suction unit and retain said crushed waste, which bag is mounted laterally suspended from said cover. Preferably, said container is a standard container for waste, equipped with wheels.
Dans un mode préférentiel de réalisation, ledit capot comporte un rebord périphérique dont la surface d'appui est de forme et de dimension compatibles avec celle du rebord périphérique extérieur à l'ouverture du conteneur, laquelle surface d 'appui est équipée d'un joint creux ou tout au moins suffisamment souple pour s'écraser par endroits et accepter ainsi les déformations de surface, lequel joint étant apte à s ' appuyer sur ledit rebord périphérique du conteneur et à rendre son ouverture etanche par rapport au capot, tout en abso rbant les vi brations du moteur. Le résultat est de nouveaux dispositifs de ramassage de déchets par aspiration , qui remédient aux inconvénients évoqués précédemment dans les dispositifs actuels et répondent au problème posé.In a preferred embodiment, said cover comprises a peripheral rim whose bearing surface is of shape and dimension compatible with that of the peripheral rim outside the opening of the container, which bearing surface is equipped with a seal hollow or at least flexible enough to crush in places and thus accept the surface deformations, which joint being able to press on said peripheral rim of the container and to make its opening watertight relative to the cover, while absorbing the vibrations of the engine. The result is new devices for collecting waste by suction, which remedy the drawbacks mentioned previously in the current devices and respond to the problem posed.
En effet, le dispositif suivant l ' invention permet à la turbine d'aspiration , dont le diamètre est de préférence supérieur à celui du tuyau d' aspiration manipulé par l ' opérateur, de créer dans celui-ci une aspiration à vitesse élevée de l' ordre de 5 à 6 mètres par seconde et même au-delà, dans la mesure où l 'étanchéite entre le dispositif d'aspiration et le conteneur est suffisamment bien réalisée, grâce en particulier au joint suivant la présente invention, qui de plus, de par sa forme, absorbe les vibrations du moteur d 'entraînement et réduit la nuisance sonore ; le courant d ' ai r ainsi créé à l 'extrémité du tuyau d 'aspiration, grâce à sa vitesse élevée , peut y entraîner des objets et déchets lourds tels que du ciment, des pierres , et pouvant êt re même de densité de 4 à 5 par exemple, et cela d 'autant plus que leur surface portante par rapport au flux de l ' ai r d' aspi ration est importante en proportion de la section du tuyau d'aspi ration : lesquel s déchets arrivent ensuite dans le haut du conteneur, dont l a section d' ouverture est bien sûr plus grande que celle du tuyau d'aspiration, ce qui fait chuter la vitesse d'entraînement de l'air, ne permettant pas alors de dévier lesdits déchets lourds, qui ont acquis une vitesse d'entraînement assez importante dans le tuyau d 'aspiration et sont donc projetés dans le conteneur suivant une direction qui les écartent justement de l 'entrée de la turbine, et cela d 'autant plus que l ' orifice du tuyau d 'aspiration arrive en haut du conteneur ; lesquels déchets lourds tombent alors dans le fond dudit conteneur ; par contre, les déchets dits légers, c 'est-à-dire de faible densité, en générale inférieure à 1 mais pouvant être de densité supérieure suivant leur voilure ou surface portante, et ayant alors une bonne prise au courant d'air, tels que par exemple des feuilles de papier, des feuilles d 'arbres, etc .. continuent d'être entraînés et déviés à travers le conteneur par l ' air aspiré à vitesse donc plus lente que dans le tuyau d'aspiration , par et vers la turbine dans et par laquelle ils sont réaccélérés et broyés, sans risque pour les pales d'aspi ration puisqu 'il ne s ' agit alors que de déchets de faible densité : leur volume est alors réduit à celui des particules ainsi broyées qui sont soufflées à la sortie de la turbine dans un sac annexe qui les retient tout en permettant également à l 'air de s ' évacuer.Indeed, the device according to the invention allows the suction turbine, the diameter of which is preferably greater than that of the suction pipe manipulated by the operator, to create therein a suction at high speed of the 'order of 5 to 6 meters per second and even beyond, insofar as the seal between the suction device and the container is sufficiently well achieved, thanks in particular to the seal according to the present invention, which moreover, by its shape, absorbs vibrations of the drive motor and reduces noise pollution; the air flow thus created at the end of the suction pipe, thanks to its high speed, can carry heavy objects and waste such as cement, stones, and can even be of density from 4 to 5 for example, and all the more so since their bearing surface in relation to the flow of the suction air is large in proportion to the section of the suction pipe: which waste then arrives at the top of the container , the opening section of which is of course larger than that of the suction pipe, which causes the air drive speed to drop, thus not making it possible to deflect said heavy waste, which has acquired a speed d quite significant entrainment in the suction pipe and are therefore projected into the container in a direction which separates them precisely from the inlet of the turbine, and this all the more as the orifice of the suction pipe arrives at the top container; which heavy waste then falls to the bottom of said container; on the other hand, so-called light waste, that is to say of low density, generally less than 1 but which may be of higher density depending on their airfoil or bearing surface, and then having a good catch in the air flow, such that for example sheets of paper, leaves of trees, etc. continue to be entrained and deflected through the container by the air sucked in at a speed therefore slower than in the suction pipe, by and towards the turbine in and by which they are re-accelerated and crushed, without risk for the suction blades since it is only a question of low density waste: their volume is then reduced to that of the particles thus crushed which are blown at the outlet of the turbine in a bag annex which retains them while also allowing air to escape.
Un tel dispositif est assez peu encombrant et reste opérationnel tant que, soit le sac de déchets légers, soit le conteneur à déchets lourds n' est pas plein ; il représente un poids à vide de l 'ordre de 6 à 7 kilos maximum, qui peut être ainsi facilement manipulable et chargé , même sur des véhicules à deux roues, car il est directement monté sur le conteneur associé, sans nécessiter de support intermédiaire. Le débit que l 'on peut obtenir avec un tel dispositif, avec un moteur d 'entraînement de type thermique de moins d'un kilowatt peut être de 10 m par minute , soit trois fois supérieur à celui des aspirateurs classiques à alimentation électrique, permettant donc une meilleure efficacité d ' aspiration tout en nécessitant moins de puissance que tous les autres types de dispositifs cités précédemment d' aspiration ; en effet, ceux-ci nécessitent une puissance plus élevée du fait que pour éviter d ' abîmer le système d' aspiration, ils comportent tous un filtre à mailles serrées avant l 'ouverture d' aspiration pour arrêter tout type de déchet qu' il soit lourd ou léger. On pourrait citer d' autres avantages de la présente invention, mais ceux cités ci-dessus en montrent déjà suffisamment pour en prouver la nouveauté et l'intérêt .Such a device is relatively compact and remains operational as long as either the light waste bag or the heavy waste container is not full; it represents an empty weight of the order of 6 to 7 kilos maximum, which can thus be easily handled and loaded, even on two-wheeled vehicles, since it is directly mounted on the associated container, without requiring any intermediate support. The flow rate that can be obtained with such a device, with a thermal type drive motor of less than one kilowatt can be 10 m per minute, or three times that of conventional vacuum cleaners with electric power, allowing therefore better suction efficiency while requiring less power than all the other types of suction devices mentioned above; indeed, these require a higher power because to avoid damaging the suction system, they all have a tight mesh filter before the suction opening to stop any type of waste heavy or light. One could cite other advantages of the present invention, but those cited above already show enough to prove the novelty and the interest.

Le capot 1 intègre et supporte le bloc d'aspiration 2 constitué d'une turbine d'aspiration et de broyage 2 λ de déchets légers 222 et dont la rotation est assurée par un moteur d'entraînement 3, de préférence de type thermique à essence, respectant les normes de pollution et de bruit et située sur le dessus du capot 1.The cover 1 integrates and supports the suction unit 2 consisting of a suction and grinding turbine 2 λ of light waste 22 2 and whose rotation is ensured by a drive motor 3, preferably of the thermal type with petrol, complying with pollution and noise standards and located on top of hood 1.
Celui-ci est également pourvu d'un orifice 7 aménagé pour recevoir un conduit basse pression flexible 8 équipé à son autre extrémité d'un tube 10 destiné à transporter les déchets 22 aspirés, par exemple sur le sol 24.The latter is also provided with an orifice 7 arranged to receive a flexible low pressure conduit 8 equipped at its other end with a tube 10 intended to transport the waste 22 sucked in, for example on the ground 24.
Le dispositif ainsi constitué permet aux déchets lourds 22 , de tomber par inertie dans le conteneur 5, alors que les déchets de faible densité 222 sont aspirés par la turbine 2 et broyés avant d'être éjectés par son orifice de refoulement 23 dans un sac de ramassage 9 placé latéralement. Le conduit flexible 8 équipé à son extrémité mobile 10 dudit tube 10, est manipulable par une poignée de maintien 1 1 dont est muni ledit tube 10.The device thus formed allows heavy waste 22 to fall by inertia into the container 5, while low density waste 22 2 is sucked by the turbine 2 and crushed before being ejected through its discharge orifice 23 in a bag collection 9 placed laterally. The flexible conduit 8 equipped at its movable end 10 with said tube 10, can be manipulated by a holding handle 11 which is provided with said tube 10.
Ladite poignée de maintien 1 1 est équipée d'une manette 14 aménagée pour commander l 'accélération du moteur d'entraînement 3 du bloc d'aspiration 2, par toute liaison mécanique ou électrique non représentée sur les figures.Said holding handle 1 1 is equipped with a handle 14 arranged to control the acceleration of the drive motor 3 of the suction unit 2, by any mechanical or electrical connection not shown in the figures.
Comme représenté sur la figure 4, ledit capot 1 comporte un rebord périphérique 17, qui peut être en forme de bride, dont la surface d' appui est de forme et de dimension compatibles avec celles du rebord périphérique 16 extérieur à l'ouverture 4 du conteneur 5, laquelle surface d' appui est équipée d'un joint souple, déformable dans son épaisseur, soit de préférence creux 6, apte à s'appuyer sur ledit rebord périphérique du conteneur 4. Un tel joint, outre l'étanchéite qu'il permet d'assurer, même en cas de déformation de la planéité du rebord 16 du conteneur, absorbe également les vibrations du moteur 3 qui ne sont ainsi pas transmises audit conteneur 5 , limitant ainsi, non seulement les nuisances sonores mais également la détérioration mécanique de l 'ensemble. De plus, ledit j oint creux 6 comporte une go rge 20 dont l'ouverture orientée vers le centre du capot 1 parallèlement à la surface d'appui du rebord 17 est apte à s'enfiler extérieurement, à cheval sur ledit rebord qui est alors nécessairement en forme de bride ou comporte une lèvre pour cela ; il est ainsi très facile de pouvoir enlever et changer le joint 6 suivant le cas.As shown in Figure 4, said cover 1 has a peripheral flange 17, which may be in the form of a flange, the bearing surface of which is of shape and dimension compatible with those of the peripheral flange 16 outside the opening 4 of container 5, which bearing surface is equipped with a flexible seal, deformable in its thickness, or preferably hollow 6, capable of pressing on said peripheral rim of the container 4. Such a seal, in addition to the seal that it ensures, even in the event of deformation of the flatness of the rim 16 of the container, also absorbs the vibrations of the motor 3 which are thus not transmitted to said container 5, thus limiting not only noise pollution but also mechanical deterioration from the whole. In addition, said hollow anointed j 6 comprises a groove 20 whose opening oriented towards the center of the cover 1 parallel to the bearing surface of the rim 17 is capable of threading externally, straddling said rim which is then necessarily in the form of a flange or has a lip for this; it is thus very easy to be able to remove and change the seal 6 as appropriate.
Pour pouvoir maintenir ledit capot 1 sur ledit conteneur 5, surtout lorsque la turbine d'aspiration 2 n'est pas en fonctionnement, ledit capot 1 comporte au moins deux systèmes d'accr.ochage 13 placés à sa périphérie extérieure, et constitués au moins d'une partie souple 18 fixée et articulée sur ledit capot 1 , et d'une partie rigide 19 apte à venir s'engager sous le rebord périphérique 16 extérieur du conteneur 5.In order to be able to maintain said cover 1 on said container 5, especially when the suction turbine 2 is not in operation, said cover 1 comprises at least two attachment systems 13 placed at its outer periphery, and constituted at least a flexible part 18 fixed and articulated on said cover 1, and a rigid part 19 capable of coming to engage under the peripheral rim 16 outside of the container 5.
Pour pouvoir protéger la turbine 2 d'aspiration quand le capot 1 est ouvert et posé indépendamment du conteneur 5, il est préférable de disposer une grille 1 5 dans la base du capot 1 sur au moins la surface de l'orifice 21 d' aspiration de ladite turbine débouchant dans ledit capot 1 . Comme indiqué précédemment , suivant les options de réalisation possibles, l ' orifice 7 du conduit 8 peut être installé, soit verticalement sur le capot 1 tel que représenté sur les figures 1 et 2A, en considérant la position verticale, celle du conteneur 5 posé sur le sol 24 tel que représenté sur la figure 1 , et selon une autre variante telle que représentée sur la figure 3 , ledit orifice 7 peut être monté horizontalement. Le dispositif selon l' invention est ainsi particulièrement destiné à aspirer tout type de déchet 22 jonchant la voie publique ou tout autre espace ouvert public ou privé 24, en ville comme à la campagne. To be able to protect the suction turbine 2 when the cover 1 is open and placed independently of the container 5, it is preferable to placing a grid 1 5 in the base of the cover 1 on at least the surface of the orifice 21 for suction of said turbine opening into said cover 1. As indicated above, according to the possible embodiment options, the orifice 7 of the duct 8 can be installed, either vertically on the cover 1 as shown in FIGS. 1 and 2A, considering the vertical position, that of the container 5 placed on the floor 24 as shown in Figure 1, and according to another variant as shown in Figure 3, said orifice 7 can be mounted horizontally. The device according to the invention is thus particularly intended for aspirating any type of waste 22 strewing on the public highway or any other open public or private space 24, in town as in the countryside.
