Its level (20) is tilted along its longitudinal length, and its lowest point (21) opens into a decanting basin (3) containing a removable filter (30), which divides the basin (3) into two chambers (31,32). The inlet chamber (31) has a discharge gate (37) at the bottom, for the sludge, while the other chamber (32) has \- 1 upper opening (34,35) for the filtered water to pass to the collection container (1).

Description

La présente invention a pour objet un dispositif de décantation et de filtration de l'eau de lavage pour une laveuse, notamment une laveuse de caisses de vendange. The subject of the present invention is a device for decanting and filtering washing water for a washer, in particular a washer for harvesting cases.

Les laveuses de caisses de vendange comportent généralement un dispositif de filtration de l'eau destiné à permettre le recyclage de celle-ci. The vintage crate washers generally include a water filtration device intended to allow its recycling.

Actuellement, la filtration est réalisée par l'intermédiaire d'un filtre disposé horizontalement au fond de la laveuse, qui présente l'inconvénient de se boucher fréquemment, ce qui nécessite des interventions entraînant des immobilisations prolongées de la laveuse. Currently, filtration is carried out by means of a filter placed horizontally at the bottom of the washer, which has the drawback of being blocked frequently, which requires interventions leading to prolonged immobilizations of the washer.

La présente invention a pour but de proposer un dispositif de décantation et de filtration pour laveuse permettant de remédier à ces divers inconvénients. The object of the present invention is to propose a settling and filtration device for a washer which makes it possible to remedy these various drawbacks.

Le dispositif de décantation et de filtration objet de la présente invention se caractérise essentiellement en ce qu'il comprend, sous la laveuse, une cuve de stockage de l'eau recyclée équipée d'une pompe permettant l'alimentation de ladite laveuse, le fond de celle-ci étant incliné dans le sens longitudinal, son extrémité la plus basse débouchant dans un bassin de décantation dans lequel est disposé verticalement, de manière amovible, un élément filtrant séparant transversalement ledit bassin en deux compartiments, le compartiment dans lequel débouche ledit fond comportant en partie basse une vanne de vidange des boues, tandis que l'autre compartiment comporte dans sa région supérieure au moins une ouverture permettant le passage de l'eau filtrée vers la cuve. The decanting and filtration device which is the subject of the present invention is essentially characterized in that it comprises, under the washer, a storage tank for recycled water equipped with a pump allowing the supply of said washer, the bottom thereof being inclined in the longitudinal direction, its lowest end opening into a settling tank in which is vertically and removably disposed a filter element dividing said basin transversely into two compartments, the compartment into which said bottom opens comprising in the lower part a sludge emptying valve, while the other compartment has in its upper region at least one opening allowing the passage of the filtered water to the tank.

Selon une caractéristique additionnelle du dispositif selon l'invention, le bassin de décantation est intégré dans la cuve. According to an additional characteristic of the device according to the invention, the settling tank is integrated into the tank.

En fonctionnement, l'eau de lavage s'écoule sur le fond de la laveuse jusqu'au bassin de décantation dans le fond duquel, du fait de l'élément filtrant, les boues s'accumulent pour être évacuées ultérieurement, tandis que l'eau filtrée s'écoule dans la cuve de stockage des eaux recyclées, où elle est pompée pour être réutilisée. In operation, the washing water flows on the bottom of the washer to the settling tank in the bottom of which, due to the filter element, the sludge accumulates to be evacuated later, while the filtered water flows into the recycled water storage tank, where it is pumped for reuse.

On notera qu'une arrivée d'eau propre dans la laveuse permet d'une part de maintenir un certain niveau d'eau, d'autre part d'augmenter le niveau d'eau pour le nettoyage du filtre, et d'autre part encore de rincer les caisses. It should be noted that a supply of clean water to the washer makes it possible on the one hand to maintain a certain level of water, on the other hand to increase the water level for cleaning the filter, and on the other hand again to rinse the crates.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé :
- la figure 1 représente une vue schématique en coupe longitudinale selon un plan vertical médian d'un dispositif de décantation et de filtration selon l'invention
- la figure 2 représente une vue schématique en coupe transversale selon l'axe XX' de la figure 1.
In the attached drawing:
- Figure 1 shows a schematic view in longitudinal section along a median vertical plane of a settling and filtration device according to the invention
- Figure 2 shows a schematic view in cross section along the axis XX 'of Figure 1.

Si on se réfère à ces figures 1 on peut voir qu'un dispositif de décantation et de filtration selon l'invention comprend une cuve 1 de stockage de l'eau recyclée, placée sous une laveuse 2 dont le fond 20 constitue également la paroi supérieure de la cuve 1. If we refer to these figures 1 we can see that a decantation and filtration device according to the invention comprises a tank 1 for storing recycled water, placed under a washer 2 whose bottom 20 also constitutes the upper wall tank 1.

Le fond 20 est incliné pour permettre l'écoulement des eaux de lavage dans un bassin de décantation 3 disposé dans la cuve 1 à l'extrémité 21 la plus basse du fond 20. The bottom 20 is inclined to allow the washing water to flow into a settling tank 3 placed in the tank 1 at the lowest end 21 of the bottom 20.

On notera qu'afin de faciliter la collecte des eaux de lavage, le fond 20 comporte un pli longitudinal médian 22 lui donnant une forme de V. Note that in order to facilitate the collection of washing water, the bottom 20 has a median longitudinal fold 22 giving it a V shape.

Le bassin 3 est divisé transversalement par un filtre 30, disposé verticalement et susceptible d'être enlevé par le dessus, séparant le bassin 3 en deux compartiments 31 et 32, l'extrémité 21 du fond 20 débouchant dans le compartiment 31. The basin 3 is divided transversely by a filter 30, arranged vertically and capable of being removed from above, separating the basin 3 into two compartments 31 and 32, the end 21 of the bottom 20 opening into the compartment 31.

Des ouvertures latérales 34 et frontales 35 sont pratiquées dans la partie supérieure du bassin 3 au niveau du compartiment 32, permettant à ce dernier de communiquer avec la cuve 1. Side 34 and front 35 openings are made in the upper part of the basin 3 at the level of the compartment 32, allowing the latter to communicate with the tank 1.

Le compartiment 31, où les eaux usées sont décantées, est équipé à proximité de son fond 36 d'une vanne de vidange 37, tandis que la cuve 1 est équipé en partie basse d'une vanne de vidange 10, et qu'une pompe 11 permet d'alimenter les éléments de lavage, non représentés, en eau provenant de la cuve 1. The compartment 31, where the wastewater is decanted, is equipped near its bottom 36 with a drain valve 37, while the tank 1 is equipped at the bottom with a drain valve 10, and a pump 11 makes it possible to supply the washing elements, not shown, with water from the tank 1.

Lors d'une opération de lavage, les eaux usées se déversent dans le compartiment 31 du bassin 3, en s'écoulant sur le fond 20. During a washing operation, the waste water is discharged into the compartment 31 of the basin 3, flowing on the bottom 20.

Dans le compartiment 31, les boues, retenues par le filtre 30, tombent sur le fond 36 et peuvent être évacuées par la vanne de vidange 37, tandis que l'eau traverse le filtre 30 pour remplir le compartiment 32 et passer de celui-ci à la cuve 1 par les ouvertures 34 et 35. In the compartment 31, the sludge, retained by the filter 30, falls on the bottom 36 and can be discharged by the drain valve 37, while the water passes through the filter 30 to fill the compartment 32 and pass from it to tank 1 through openings 34 and 35.

Lors de l'évacuation des boues par la vanne de vidange 37, l'eau contenue dans le compartiment 32 traverse le filtre 30 en sens inverse et nettoie celui-ci ainsi que le compartiment 31. When the sludge is discharged through the drain valve 37, the water contained in the compartment 32 passes through the filter 30 in the opposite direction and cleans the latter as well as the compartment 31.

Cette opération d'évacuation des boues et de nettoyage du filtre 30 peut être effectuée rapidement, elle est avantageusement réalisée en fin de cycle de lavage après le rinçage, lorsque le niveau d'eau est au maximum puisque le rinçage est réalisé au moyen d'eau propre, amenée par une arrivée 22 visible sur la figure 1, et qui s'ajoute à l'eau recyclée. This sludge evacuation and filter 30 cleaning operation can be carried out quickly, it is advantageously carried out at the end of the washing cycle after rinsing, when the water level is at its maximum since the rinsing is carried out by means of clean water, brought by an inlet 22 visible in Figure 1, and which is added to the recycled water.

I1 va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention.  It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.
