La présente invention porte sur une turbine d'aspiration pour un dispositif de nettoyage de surfaces dallées, pavées ou bétonnées en particulier pour un véhicule automobile de nettoyage urbain, elle concerne également les dispositifs et les véhicules automobiles de nettoyage équipés d'une telle turbine. The present invention relates to a suction turbine for a device for cleaning paved, paved or concrete surfaces, in particular for a motor vehicle for urban cleaning, it also relates to devices and motor vehicles for cleaning equipped with such a turbine.
Un véhicule du type précité est par exemple décrit dans les brevets et demandes de brevet de la demanderesse FR 2 626 911 FR-FR 2 733 775- FR 99 07 897-FR 00 13 107. A vehicle of the aforementioned type is for example described in the patents and patent applications of the applicant FR 2 626 911 FR-FR 2 733 775- FR 99 07 897-FR 00 13 107.
Il comporte notamment une cuve de collecte des déchets fixée sur un châssis, avec une turbine d'aspiration d'axe vertical fixée, par exemple en position inversée, sur le dessus du plafond mobile de la benne. In particular, it includes a waste collection tank fixed to a chassis, with a vertical axis suction turbine fixed, for example in an inverted position, on top of the movable ceiling of the bucket.
Les déchets ramassés sur la surface par un ensemble de brossage sont aspirés et conduits à travers un tuyau jusque dans la cuve dans laquelle ils se déposent, tandis que l'air aspiré par la turbine est rejeté en bas du véhicule à travers un conduit longeant extérieurement la cuve. The waste picked up on the surface by a brushing assembly is sucked and led through a pipe to the tank in which it is deposited, while the air sucked by the turbine is discharged at the bottom of the vehicle through a pipe running along the outside tank.
En outre, lorsque ce véhicule est employé également pour le lavage des surfaces il est équipé par exemple d'un dispositif d'aspersion de liquide de nettoyage, et d'un dispositif qui aspire le mélange liquide-saletés résultant du brossage-nettoyage de la surface puis l'envoie dans la turbine. In addition, when this vehicle is also used for washing surfaces, it is equipped, for example, with a device for spraying cleaning liquid, and with a device which sucks the liquid-dirt mixture resulting from brushing-cleaning the surface then sends it to the turbine.
Le problème à résoudre consiste dans le fait que la turbine reçoit en entrée un mélange d'air et de gouttelettes d'eau ou de liquide qui, sous l'effet de la force centrifuge sont projetées sur les parois latérales de la turbine et ressortent, au moins en partie par la bouche de sortie provoquant un écoulement par le conduit précité. The problem to be solved consists in the fact that the turbine receives at the inlet a mixture of air and droplets of water or liquid which, under the effect of centrifugal force are projected on the side walls of the turbine and come out, at least in part by the outlet mouth causing a flow through the aforementioned conduit.
La présente invention a pour but de proposer une solution à ce problème, grâce à une turbine d'aspiration, par exemple pour un dispositif de nettoyage de surfaces dallées, pavées ou bétonnées, en particulier mais non limitativement pour un véhicule automobile de nettoyage urbain, comportant un carter formé de deux surfaces planes l'une inférieure et l'autre supérieure, et d'une paroi latérale cylindrique, ladite turbine étant apte à aspirer l'air par une bouche d'entrée prévue en position centrale sur une des surfaces planes du carter et à rejeter l'air par une bouche de sortie latérale, caractérisée en ce qu'elle comporte, avant la bouche de sortie un moyen de piégeage apte à piéger des gouttelettes mélangées à l'air aspiré par la bouche d'entrée et un moyen d'évacuation de ces gouttelettes apte à les évacuer à l'extérieur du carter. The present invention aims to provide a solution to this problem, using a suction turbine, for example for a device for cleaning paved, paved or concrete surfaces, in particular but not limited to an urban cleaning motor vehicle, comprising a casing formed by two flat surfaces, one lower and the other upper, and a cylindrical side wall, said turbine being capable of sucking air through an inlet mouth provided in a central position on one of the flat surfaces of the casing and to reject the air by a lateral outlet mouth, characterized in that it comprises, before the outlet mouth, a trapping means capable of trapping droplets mixed with the air sucked in by the inlet mouth and a means of evacuation of these droplets capable of evacuating them outside the casing.
Avec une turbine selon l'invention, il n'y a plus d'écoulement d'eau ou de liquide par la bouche de sortie de la turbine. With a turbine according to the invention, there is no longer any flow of water or liquid through the outlet outlet of the turbine.

On comprendra mieux l'invention à l'aide de la description ci-après d'un mode de réalisation donné à titre d'exemple non limitatif de l'invention, faite en référence aux figures annexées suivantes : figure 1 : vue en coupe verticale d'une cuve de véhicule de nettoyage montrant la position de la turbine et la circulation de l'air dans la cuve, figure 2 : vue de dessus d'une turbine selon l'invention, installée dans la cuve de la figure 1
La turbine (1) représentée en figure 1 à titre d'exemple non limitatif est montée en position inversée, dans un caisson (2) situé en haut de la cuve (3) à déchets sous le couvercle amovible (4). The invention will be better understood with the aid of the description below of an embodiment given by way of nonlimiting example of the invention, made with reference to the following appended figures: FIG. 1: view in vertical section of a cleaning vehicle tank showing the position of the turbine and the air circulation in the tank, Figure 2: top view of a turbine according to the invention, installed in the tank of Figure 1
The turbine (1) shown in Figure 1 by way of non-limiting example is mounted in the inverted position, in a box (2) located at the top of the waste tank (3) under the removable cover (4).
Les déchets solides (5) (poussières et gros déchets) s'amassent dans la cuve et un mélange d'air et de gouttelettes (6) traverse une ouverture grillagée (7) du caisson et, entre dans la turbine par sa bouche d'entrée (8) prévue en position centrale sur le dessus du carter (9) de la turbine. Solid waste (5) (dust and large waste) collects in the tank and a mixture of air and droplets (6) passes through a screened opening (7) of the box and enters the turbine through its mouth. inlet (8) provided in central position on top of the casing (9) of the turbine.
A l'intérieur de la turbine, les gouttelettes d'eau ou de liquide sont projetées vers la périphérie, sur la paroi latérale (10) et entraînées vers la sortie puis sont piégées juste avant la bouche de sortie (11) par une tôle (12) de même hauteur que la paroi latérale (10), ladite tôle étant soudée ou fixée sur la paroi latérale (10) par son extrémité la plus proche de la sortie, son autre extrémité étant écartée de ladite paroi d'une valeur prédéterminée par exemple 30 mm. Inside the turbine, the droplets of water or liquid are projected towards the periphery, on the side wall (10) and entrained towards the outlet then are trapped just before the outlet mouth (11) by a sheet ( 12) of the same height as the side wall (10), said sheet being welded or fixed to the side wall (10) by its end closest to the outlet, its other end being separated from said wall by a value predetermined by example 30 mm.
Au voisinage du sommet du secteur angulaire (a) de piégeage ainsi formé et à l'intérieur de celui-ci, on prévoit une fente verticale (13) sur toute la hauteur de la paroi latérale (10), pour évacuer l'eau piégée en dehors de la turbine et la faire tomber dans la cuve (3). Le secteur angulaire (a) aura de préférence une valeur de 3 à 50 environ. In the vicinity of the top of the angular trapping sector (a) thus formed and inside it, a vertical slot (13) is provided over the entire height of the side wall (10), to evacuate the trapped water. outside the turbine and drop it into the tank (3). The angular sector (a) will preferably have a value of around 3 to 50.
La fente (13) a une largeur prédéterminée calculée pour ne pas modifier la pression d'aspiration, par exemple 10 mm, ni créer de turbulences dans la cuve, ladite largeur pouvant être réglable par tout moyen de réglage approprié. The slot (13) has a predetermined width calculated so as not to modify the suction pressure, for example 10 mm, or to create turbulence in the tank, said width being adjustable by any suitable adjustment means.
La turbine selon l'invention fonctionne de la même manière si l'air admis par l'entrée contient en plus des gouttelettes : des poussières et/ou des petites particules solides, telles que grains de sable ou petits graviers, ces particules étant piégées également par la tôle et évacuées par la fente pour tomber dans la cuve. The turbine according to the invention operates in the same way if the air admitted by the inlet contains in addition droplets: dust and / or small solid particles, such as grains of sand or small gravel, these particles also being trapped by the sheet and discharged through the slot to fall into the tank.
Selon l'utilisation, on peut être amené à optimiser le piégeage des gouttelettes en réglant la vitesse de rotation de la turbine, à laquelle on adjoint un moyen de régulation de sa vitesse de rotation. Depending on the use, it may be necessary to optimize the trapping of the droplets by adjusting the speed of rotation of the turbine, to which a means of regulating its speed of rotation is added.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
On optimise également le piégeage des gouttelettes en améliorant l'étanchéité au niveau du couvercle (14) et au niveau des liaisons (15-16) entre le caisson et la turbine. The trapping of the droplets is also optimized by improving the seal at the cover (14) and at the connections (15-16) between the box and the turbine.
Le moyen de piégeage et le moyen d'évacuation des gouttelettes qui viennent d'être décrits peuvent être prévus sur d'autres types de turbine, en particulier sur des turbines non inversées ou des turbines verticales. The trapping means and the means for discharging the droplets which have just been described can be provided on other types of turbine, in particular on non-inverted turbines or vertical turbines.
L'invention concerne également un véhicule automobile de nettoyage, comportant au moins des moyens de lavage de surfaces dont un dispositif d'aspersion de liquide de nettoyage et un dispositif d'aspiration dudit liquide, caractérisé en ce qu'il comporte une turbine du tube décrit ci-dessus. The invention also relates to a motor vehicle for cleaning, comprising at least means for washing surfaces, including a device for spraying cleaning liquid and a device for aspirating said liquid, characterized in that it comprises a turbine of the tube. described above.
