Definitions
- extractors centrifuges in which the tank surrounding the basket is arranged in the manner of a door hinged on the front part of the fixed frame, so as to surround said basket.
- the present invention is based on the observation that such an articulated tank wringer is capable, by means of a relatively simple adaptation, of lending itself particularly well to centrifugal filtration operations in a sterile atmosphere, for example in chemical or pharmaceutical laboratories. , since the rear part of the machine containing the feed and drive devices, the decontamination of which is always difficult, is likely to be placed in a room different from that containing the front part comprising the articulated tank and the basket on the wall of which the solid particles obtained are deposited by centrifugation.
- the fixed frame is made to comprise, immediately behind the opening against which the edge of the tank comes to apply in the closed position, a plate which is oriented transversely to the axis of the rotating basket and which is tightly connected to the edge of the abovementioned hole by a deformable element.
- the reference 1 designates a vertical partition separating two contiguous premises referenced A and B, which partition 1 is pierced with a hole 1 a which one can suppose to be established in a substantially rectangular section.
- the wringer according to the invention is intended to be installed inside this hole 1 a , so that its front part is located in room A with sterile atmosphere, while its rear part is arranged in the room B with an uncontrolled atmosphere.
- the centrifugal wringer considered is of conventional construction as regards its general arrangement. Its fixed frame 2 which contains the lateral ballast boxes and the hydraulic group for controlling the usual picking knife and which supports the motor 3 for driving the rotating basket 4, is mounted on a lower platform 5, which is supported by damping systems 6 against the upper face of a solid block 7 provided on the floor of room B. On the other hand, the aforementioned basket 4, the tank 8 which envelops this basket and the mechanisms associated with the bottom of said tank 8 are located inside room A, with the tubing 9 used for the recovery of solid particles separated by centrifugal effect and normally collected against the inner wall of the basket.
- this tank 4 is of the articulated type, in the sense that it is pivotally supported by a vertical axis integral with the frame 2 and that it is capable of being kept closed during centrifugation using a flange mechanism 10, its open edge being retained applied in leaktight manner against a bearing surface surrounding the opening of the frame 2.
- the frame 2 is made integral, for example by welding, a vertical plate 11 whose profile elevation is similar to that of the hole 1a. Furthermore, the peripheral edge of this plate 11 is connected to the edge of the gap 1 a by a sealed and deformable system referenced 12 in FIG. 1 and which has been illustrated in FIG. 2 an example of practical implementation.
- this system comprises a flexible element 13 made of a waterproof synthetic material, which has a U-shaped profile in cross section, it being observed that the central part comprises at least one longitudinal fold 13 a which allows said element to deform at the like a bellows.
- One of the lateral branches of the aforementioned profile is fixed against the partition 1 using sealed bolts 14 and a flange 15, while the other branch is attached, also using bolts 14 and a flange 15, against the outermost wing of a frame 16 with a double angle section, made integral with the plate 11 of the fixed frame 2 of the wringer.
- the plate 11 and the deformable system 12 ensure the perfectly sealed separation of the two premises A and B despite the fact that the centrifugal wringer according to the invention is arranged astride a hole made in the intermediate partition 1.
- the recovery of the solid phase, as the packaging of the extracted product, are therefore likely to be operated in a perfectly sterile atmosphere while the filtrate can be evacuated through a side tube 17 oriented rearward, in room B
- the vibrations generated by the operation of the machine are collected by the system 12 and are therefore not transmitted to the partition 1.

Abstract
Description
On sait qu'en vue d'améliorer les conditions d'accessibilité au panier tournant et aux accessoires qui lui sont associés, de faciliter le nettoyage et de permettre un contrôle visuel aisé des opérations de filtration sans démontage des pièces, on a proposé des essoreuses centrifuges dans lesquelles la cuve entourant le panier est agencée à la manière d'une porte articulée sur la partie antérieure du bâti fixe, de façon à entourer ledit panier.We know that in order to improve the conditions of accessibility to the revolving basket and the accessories associated with it, to facilitate cleaning and to allow easy visual control of filtration operations without dismantling the parts, we have used extractors centrifuges in which the tank surrounding the basket is arranged in the manner of a door hinged on the front part of the fixed frame, so as to surround said basket.
La présente invention est fondée sur l'observation qu'une telle essoreuse à cuve articulée est de nature, moyennant une adaptation relativement simple, à se prêter particulièrement bien à des opérations de filtration centrifuge en atmosphère stérile, par exemple dans les laboratoires chimiques ou pharmaceutiques, puisque la partie arrière de la machine renfermant les dispositifs d'alimentation et d'entraînement, dont la décontamination est toujours malaisée, est susceptible d'être disposée dans un local différent de celui renfermant la partie antérieure comprenant la cuve articulée et le panier sur la paroi duquel se déposent par centrifugation les particules solides obtenues.The present invention is based on the observation that such an articulated tank wringer is capable, by means of a relatively simple adaptation, of lending itself particularly well to centrifugal filtration operations in a sterile atmosphere, for example in chemical or pharmaceutical laboratories. , since the rear part of the machine containing the feed and drive devices, the decontamination of which is always difficult, is likely to be placed in a room different from that containing the front part comprising the articulated tank and the basket on the wall of which the solid particles obtained are deposited by centrifugation.
C'est cette adaptation qui fait l'objet de la présente invention, laquelle vise l'essoreuse centrifuge qui est définie à la revendication 1.It is this adaptation which is the subject of the present invention, which relates to the centrifugal wringer which is defined in
En fait, conformément à l'invention, s'agissant d'une essoreuse centrifuge destinée à être implantée dans une trouée pratiquée dans une cloison séparant deux locaux contigus propres à renfermer l'un la partie arrière d'entraînement de la machine, l'autre la partie avant avec la cuve articulée, l'on fait comporter au bâti fixe, immédiatement en arrière de l'ouverture contre laquelle vient s'appliquer le bord de la cuve à la position fermée, une plaque qui est orientée transversalement à l'axe du panier tournant et qui est reliée de manière étanche au bord de la trouée précitée par un élément déformable.In fact, in accordance with the invention, in the case of a centrifugal wringer intended to be installed in a hole made in a partition separating two adjoining rooms suitable for enclosing one the rear drive part of the machine, the other the front part with the articulated tank, the fixed frame is made to comprise, immediately behind the opening against which the edge of the tank comes to apply in the closed position, a plate which is oriented transversely to the axis of the rotating basket and which is tightly connected to the edge of the abovementioned hole by a deformable element.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :
- Fig. 1 est une vue schématique de côté illustrant l'implantation d'une essoreuse centrifuge suivant la présente invention.
- Fig. 2 est une coupe de détail à plus grande échelle.
- Fig. 1 is a schematic side view illustrating the installation of a centrifugal wringer according to the present invention.
- Fig. 2 is a detail section on a larger scale.
Sur ce dessin la référence 1 désigne une cloison verticale séparant deux locaux contigus référencés A et B, laquelle cloison 1 est percée d'une trouée 1a qu'on peut supposer être établie à une section substantiellement rectangulaire. L'essoreuse suivant l'invention est destinée à être implantée à l'intérieur de cette trouée 1a, de façon à ce que sa partie antérieure se trouve située dans le local A à atmosphère stérile, tandis que sa partie arrière est disposée dans le local B à atmosphère non contrôlée.In this drawing, the
L'essoreuse centrifuge considérée est de construction classique en ce qui concerne son agencement général. Son bâti fixe 2 qui renferme les caissons latéraux de lestage et le groupe hydraulique pour la commande du couteau usuel de prélèvement et qui supporte le moteur 3 pour l'entraînement du panier tournant 4, est monté sur une plateforme inférieure 5, laquelle prend appui par des systèmes amortisseurs 6 contre la face supérieure d'un bloc massif 7 prévu sur le plancher du local B. Par contre, le panier 4 précité, la cuve 8 qui enveloppe ce panier et les mécanismes associés au fond de ladite cuve 8 se trouvent situés à l'intérieur du local A, avec la tubulure 9 utilisée pour la récupération des particules solides séparées par effet centrifuge et normalement recueillies contre la paroi intérieure du panier.The centrifugal wringer considered is of conventional construction as regards its general arrangement. Its
Il convient d'observer que cette cuve 4 est du type articulé, en ce sens qu'elle est supportée à pivotement par un axe vertical solidaire du bâti 2 et qu'elle est susceptible d'être maintenue fermée pendant la centrifugation à l'aide d'un mécanisme de brides 10, son bord ouvert étant retenu appliqué de manière étanche contre une portée entourant l'ouverture du bâti 2.It should be observed that this
Conformément à la présente invention, immédiatement en arrière de cette portée, le bâti 2 est rendu solidaire, par exemple par soudure, d'une plaque verticale 11 dont le profil en élévation est similaire à celui de la trouée 1a. Par ailleurs le bord périphérique de cette plaque 11 est relié au bord de la trouée 1a par un système étanche et déformable référencé 12 en fig. 1 et dont on a illustré en fig. 2 un exemple de réalisation pratique.According to the present invention, immediately behind this scope, the
Comme montré ce système comprend un élément souple 13 en une matière synthétique étanche, qui présente en section transversale un profil en forme de U, étant observé que la partie centrale comporte au moins un pli longitudinal 13a qui permet audit élément de se déformer à la manière d'un soufflet. L'une des branches latérales du profil précité est fixée contre la cloison 1 à l'aide de boulons scellés 14 et d'une bride 15, tandis que l'autre branche est rapportée, également à l'aide de boulons 14 et d'une bride 15, contre l'aile la plus extérieure d'un encadrement 16 à section en double équerre, rendu solidaire de la plaque 11 du bâti fixe 2 de l'essoreuse.As shown, this system comprises a
On conçoit que la plaque 11 et le système déformable 12 assurent la séparation parfaitement étanche des deux locaux A et B en dépit du fait que l'essoreuse centrifuge suivant l'invention se trouve disposée à cheval dans une trouée pratiquée dans la cloison intermédiaire 1. La récupération de la phase solide, comme le conditionnement du produit extrait, sont de ce fait susceptibles d'être opérés en atmosphère parfaitement stérile tandis que le filtrat peut être évacué à travers une tubulure latérale 17 orientée vers l'arrière, dans le local B. Les vibrations engendrées par le fonctionnement de la machine sont encaissées par le système 12 et ne sont de ce fait pas transmises à la cloison 1.It will be understood that the
Il doit être noté que si l'invention semble plus particulièrement applicable aux essoreuses centrifuges à axe horizontal, elle est toutefois apte à être mise en oeuvre avec des machines à axe vertical dans lesquelles la cuve entourant le panier tournant est constituée par un couvercle articulé.It should be noted that if the invention seems more particularly applicable to centrifugal dryers with a horizontal axis, it is however able to be implemented with machines with a vertical axis in which the tank surrounding the rotating basket is constituted by an articulated cover.
