Description
FILTRE TOURNANT A DISQUES POUR LA PURIFICATIONDISC ROTATING FILTER FOR PURIFICATION
MECANIQUE DE L'EAU.MECHANICAL WATER.
L'invention a pour objet un filtre tournant pour la purification mécanique de l'eau, filtre comportant au moins deux disques de filtration circulaires montés sur un arbre à l'intérieur d'un carter et dont les bords extérieurs sont rendus étanches afin de former une chambre annulaire de filtration à l'intérieur du carter avec un décalage relatif des entrées et des sorties des chambres successives. The invention relates to a rotating filter for the mechanical purification of water, which filter comprises at least two circular filter discs mounted on a shaft inside a housing and whose outer edges are sealed to form an annular filtration chamber inside the housing with a relative offset of the inputs and outputs of the successive chambers.
On connait déjà de tels filtres, par exemple par le brevet allemand 16 36366. Such filters are already known, for example from German Patent No. 36366.
Ces filtres antérieurs comportent bien des chambres destinées à recevoir le liquide à filtrer et o le cours du remplissage des chambres est réglé par un flotteur de manière These prior filters have well chambers for receiving the liquid to be filtered and o the course of the filling of the chambers is regulated by a float so
à ce que les disques filtrants présentent toujours une certaine profondeur d'immersion. the filter discs always have a certain depth of immersion.
On ne peut incorporer un tel dispositif à un filtre monté dans un conduit servant à la circulation d'un liquide à alimentation variable. Il est même essentiel dans ce cas d'établir le carter de manière à assurer un guidage impeccable de la garniture du disque filtrant par rapport au carter. De plus, la surface filtrante disponible sur le disque ne Such a device can not be incorporated in a filter mounted in a conduit for the circulation of a variable feed liquid. It is even essential in this case to establish the housing so as to ensure impeccable guidance of the lining of the filter disk relative to the housing. In addition, the filter surface available on the disc does not

L'invention se propose d'éliminer les inconvénients ci-dessus et d'établir un filtre tel que l'on n'ait pas besoin d'une tolérance d'usinage particulière pour les disques The invention proposes to eliminate the above disadvantages and to establish a filter such that one does not need a particular machining tolerance for the disks.

On arrive au résultat ainsi défini en maintenant l'écartement entre le carter et les disques de filtration par des galets tandis que ces disques présentent un grand We arrive at the result thus defined by maintaining the spacing between the housing and the filter discs by rollers while these discs have a large

laire. On a représenté à titre d'exemple aux dessins ci-joints une forme d'exécution de l'invention. Sur ces dessins en partie schématiques lar. An embodiment of the invention is shown by way of example in the accompanying drawings. On these partly schematic drawings
La Fig. 1 est une coupe horizontale du filtre. Fig. 1 is a horizontal section of the filter.
La Fig. 2 en est une coupe suivant la ligne Il-Il de la Fig. 1 La Fig. 3 est une vue à plus grande échelle d'une partie de la Fig. 1 Sur l'arbre 1, monté de manière à tourner entre les parois 2 d'un conduit servant à l'écoulement d'un liquide, sont assujettis des disques de filtration circulaires 3,tous Fig. 2 is a section along line II-II of FIG. 1 FIG. 3 is an enlarged view of a portion of FIG. 1 On the shaft 1, mounted to rotate between the walls 2 of a conduit for the flow of a liquid, there are affixed circular filter discs 3, all

tions 4 en forme de troncs de cône à section droite triangulaire. Ces saillies 4 sont en tissu du textile dit " nylon " et leurs faces sont gauchies sur une hauteur constante sur toute leur étendue. Les disques de filtration 3 sont entourés par un carter en tôle 5 dont les entrées de liquide 6 sont décalées horizontalement et angulairement par rapport aux sorties 7. Cette disposition permet de délimiter entre deux disques successifs des chambres 8,9 s'ouvrant alternativement vers la gauche et la droite de la Fig. 1 -2 - grâce à quoi les chambres 8 s'ouvrent vers l'admission d'eau sale et les chambres 9 vers la sortie d'eau purifiée. On rend ainsi possible de placer, au-dessus de l'arbre 1 et entre deux disques successifs 3, des passerelles accessibles 10 servant à la surveillance des tubulures d'injection et des disques de filtration 3. Lorsque le niveau d'eau varie peu au droit de l'admission et de l'évacuation, l'arbre 1 se trouve maintenu en place. S'il se produit des variations plus importantes du niveau de l' eau, on dott régler l'arbre 1 en fonction de ces variations de niveau ou bien l'arbre règle lui-même sa position en fonction de ce niveau par des moyens qui n'ont pas été représentés pour ne pas encombrer le dessin. Entre le carter 5 et les disques de filtration 3 sont montés des galets 11 ( Fig. 3) qui, d'une part transmettent le poids du carter 4 à l'arbre 1 et qui, d'autre part, assurent le maintien d'un écartement constant entre le carter 5 et les disques successifs 3. De plus, il- est prévu entre le carter 5 et les disques de filtration 3 des garnitures d'étanchéité 12. Ces dernières empêchent l'eau sale de 4 in the form of truncated cone with triangular cross section. These projections 4 are made of textile fabric called "nylon" and their faces are warped to a constant height over their entire extent. The filtration disks 3 are surrounded by a sheet metal casing 5, the liquid inlets 6 of which are offset horizontally and angularly with respect to the outlets 7. This arrangement makes it possible to delimit between two successive disks chambers 8, 9 opening alternately towards the left and right of FIG. 1 -2 - whereby the chambers 8 open to the intake of dirty water and the chambers 9 to the outlet of purified water. It is thus possible to place, above the shaft 1 and between two successive disks 3, accessible bridges 10 used for monitoring the injection pipes and filtration disks 3. When the water level varies little at the right of admission and evacuation, the shaft 1 is kept in place. If there are more significant variations in the water level, the tree 1 must be adjusted according to these variations in level or the tree itself adjusts its position according to this level by means which have not been represented so as not to clutter the drawing. Between the casing 5 and the filter discs 3 are mounted rollers 11 (FIG 3) which, on the one hand transmit the weight of the casing 4 to the shaft 1 and which, on the other hand, ensure the maintenance of a constant spacing between the housing 5 and the successive discs 3. In addition, there is provided between the housing 5 and the filter discs 3 of the seal 12. These latter prevent the dirty water from
