Description

REGISTRE A GLISSIERE POUR SYSTEME D'EXTRACTION DE FLUIDE ET INSTALLATION COMPORTANT UN TEL REGISTRE A GLISSIERE SLIDE REGISTER FOR FLUID EXTRACTION SYSTEM AND INSTALLATION HAVING SUCH A SLIDER REGISTER
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention se rapporte au domaine technique général des dispositifs de fermeture à glissière à usage industriel utilisés notamment dans ies systèmes d'extraction de fluide, en particulier d'air, de tels systèmes étant mis en œuvre dans des industries diverses, et notamment dans l'industrie de travail et de transformation du bois et/ou du métal ou encore dans l'industrie agroalimentaire. The present invention relates to the general technical field of zipper devices for industrial use used in particular in fluid extraction systems, in particular air, such systems being implemented in various industries, and particularly in the wood and / or metal working and processing industry or the agri-food industry.
L'invention concerne plus particulièrement un registre à glissière destiné à être connecté à une canalisation d'un système d'extraction de fluide, ledit registre comportant : The invention relates more particularly to a slide damper intended to be connected to a pipe of a fluid extraction system, said damper comprising:
- un bâti support pourvu d'un orifice qui est destiné à être connecté de manière sensiblement étanche avec la canalisation, de manière que l'orifice et la canalisation soient sensiblement alignés, - un volet monté mobile sur le bâti support avec une possibilité de déplacement entre une position de fermeture sensiblement étanche de l'orifice et une position d'ouverture dégageant l'orifice, - A support frame provided with an orifice which is intended to be connected substantially sealingly with the pipe, so that the orifice and the pipe are substantially aligned, - a flap mounted to move on the support frame with a possibility of displacement between a substantially sealed closure position of the orifice and an open position clearing the orifice,
- un moyen de commande et de déplacement du volet. a means for controlling and moving the shutter.
TECHNIQUE ANTERIEURE Les registres à glissière sont connus et largement utilisés dans de nombreuses applications industrielles, en particulier dans les installations industrielles de transformation ou de traitement du bois, des céréales, des métaux, des fumées, les opérations industrielles générant une grande quantité de fluide, principalement gazeux, dont il convient de maîtriser et gérer de manière optimale l'extraction et le traitement pour des raisons environnementales évidentes. Les registres à glissière connus comportent en général un bâti support pourvu d'un orifice qui est destiné à être connecté de manière sensiblement étanche avec la canalisation d'un système d'extraction de fluide sur lequel le registre est installé, de manière à ce que l'orifice et la canalisation soient sensiblement alignés. Le bâti support est pourvu d'un volet ou d'une glissière monté(e) mobile sur le bâti support avec une possibilité de déplacement entre une position de fermeture sensiblement étanche de l'orifice et une position d'ouverture dégageant l'orifice. PRIOR ART Sliding registers are known and widely used in many industrial applications, in particular in industrial plants for the processing or treatment of wood, cereals, metals, fumes, industrial operations generating a large amount of fluid, mainly gaseous, which must be controlled and managed optimally extraction and treatment for obvious environmental reasons. Known slide registers generally include a support frame provided with an orifice which is intended to be substantially sealingly connected with the pipe of a fluid extraction system on which the register is installed, so that the orifice and the pipe are substantially aligned. The support frame is provided with a flap or slide mounted (e) movable on the support frame with a possibility of movement between a substantially sealed closure position of the orifice and an open position clearing the orifice.
Les registres à glissière connus comportent également de manière classique un moyen de commande et de déplacement du volet ou de la glissière incluant un ou plusieurs vérins, de type pneumatique par exemple, pour assurer la commande et le déplacement du volet ou de la glissière entre les positions de fermeture et d'ouverture. Known slider registers also conventionally include means for controlling and moving the shutter or slider including one or more cylinders, pneumatic type for example, to ensure the control and movement of the shutter or the slide between the slats. closing and opening positions.
Les registres à glissière sont ainsi intégrés dans des réseaux de canalisation d'aspiration faisant partie de systèmes d'extraction de fluide. Ils ont pour fonction d'obturer ou de laisser libre le passage de la canalisation sur laquelle ils sont montés, ladite canalisation reliant, au sein d'un réseau complexe de canalisations, les machines de travail où sont générés les flux de fluides indésirables et à traiter, notamment gazeux, qu'il convient d'extraire et de conduire vers des installations de filtration. The slide registers are thus integrated into suction pipe networks forming part of fluid extraction systems. Their function is to close or to leave free passage of the pipe on which they are mounted, said pipe connecting, within a complex network of pipes, the working machines where undesirable fluid flows are generated and to treat, especially gaseous, that should be extracted and lead to filtration facilities.
Les registres à glissière permettent ainsi de piloter et gérer au mieux l'exploitation et l'extraction des fluides produits au sein d'une installation comportant une pluralité de machines de travail. Ainsi, en permettant par exemple de fermer la ou les canalisations reliées à des machines ne fonctionnant pas ou étant en phase de réparation, ils sont la source d'une économie globale d'énergie. The slide registers thus make it possible to control and manage the operation and extraction of the fluids produced within an installation comprising a plurality of working machines. Thus, by allowing for example to close the pipe or pipes connected to machines not working or being in the repair phase, they are the source of a global energy saving.
Il est déjà connu d'utiliser un registre à glissière pourvu d'un bâti support métallique dans lequel est monté mobile un volet ou registre également métallique qui vient fermer ou dégager l'orifice du bâti et par conséquent fermer ou ouvrir le passage du fluide dans la canalisation du système d'extraction auquel le registre est connecté. En position fermée, l'étanchéité de la fermeture par le volet est assurée à l'aide d'une couronne en matière plastique solidaire de l'orifice du bâti support et formant un joint d'étanchéité annulaire. Dans sa position de fermeture, le volet vient en effet en contact étanche avec la couronne plastique qui assure l'étanchéité de la fermeture. Ce système connu de l'art antérieur, même s'il donne globalement satisfaction, souffre néanmoins de divers inconvénients. It is already known to use a slide damper provided with a metal support frame in which is mounted movable shutter or also metal damper that comes close or clear the hole of the frame and therefore close or open the passage of the fluid in the channeling of the extraction system to which the register is connected. In the closed position, the sealing of the closure by the flap is provided by means of a plastic ring integral with the orifice of the support frame and forming an annular seal. In its closed position, the flap comes into sealing contact with the plastic crown which seals the closure. This system known from the prior art, even if it gives overall satisfaction, nevertheless suffers from various disadvantages.
Il s'avère tout d'abord que l'étanchéité réalisée par un tel montage n'est pas optimale et a par ailleurs tendance à se détériorer au fil du temps et de l'utilisation du registre. It turns out first of all that the sealing achieved by such an assembly is not optimal and also tends to deteriorate over time and the use of the register.
Dans ces dispositifs de l'art antérieur connu, le montage de la glissière est en effet dit « flottant » car pour pouvoir assurer le coulissement de la glissière entre sa position d'ouverture et de fermeture, la glissière est montée avec un jeu de fonctionnement de l'ordre de quelques millimètres dans le bâti support tout en étant en contact sensiblement étanche avec la couronne plastique seulement dans la zone annulaire de contact située à l'interface entre la couronne et le volet. II s'ensuit qu'en dehors de la zone de contact annulaire, le volet est flottant. Ce type de montage ne permet pas d'obtenir une étanchéité optimale en position de fermeture du volet, les conditions d'étanchéité ayant par ailleurs tendance à se dégrader après une certaine période d'utilisation en raison notamment de l'usure des pièces et de leur déformation. II s'avère par ailleurs que le montage dit « flottant » est la source de phénomènes vibratoires susceptibles de perturber la bonne évacuation des fluides susceptibles et de causer des phénomènes de nuisances sonores. In these known prior art devices, the mounting of the slide is indeed called "floating" because to be able to ensure the sliding of the slide between its open position and closing, the slide is mounted with a set of operation of the order of a few millimeters in the support frame while being in substantially sealed contact with the plastic crown only in the annular contact area located at the interface between the ring and the flap. It follows that outside the annular contact zone, the flap is floating. This type of assembly does not make it possible to obtain optimum sealing in the closed position of the shutter, the sealing conditions having also tend to deteriorate after a certain period of use, in particular because of the wear of the parts and the their deformation. It also turns out that the so-called "floating" assembly is the source of vibratory phenomena likely to disturb the good evacuation of the likely fluids and to cause phenomena of noise nuisance.
En dernier lieu, il y a lieu de remarquer que la dégradation progressive des caractéristiques de la fermeture étanche des registres de l'art antérieur connu conduit à une perturbation de fonctionnement de l'ensemble du système d'extraction ce qui conduit non seulement à une dégradation de la qualité du traitement des nuisances auxquels les registres à glissière participent, mais encore à une dégradation des conditions économiques de fonctionnement de telles installations dans la mesure où la réduction de la consommation d'énergie supposée être apportée par l'emploi des registres à glissière s'avère inexistante ou fortement réduite en raison précisément de la dégradation des conditions de fonctionnement d'étanchéité des registres à glissière. Finally, it should be noted that the progressive degradation of the characteristics of the sealed closure of the registers of the known prior art leads to a disturbance in the operation of the entire extraction system which leads not only to deterioration of the quality of the treatment of the nuisances to which the slide registers participate, but also to a deterioration of the economic conditions of operation of such installations insofar as the Reduction of the energy consumption assumed to be brought about by the use of the slider registers is either non-existent or greatly reduced precisely because of the deterioration of the sealing operating conditions of the slider registers.
Les conditions économiques d'exploitation de l'ensemble des systèmes d'extraction de fluide sont alors dégradées. The economic operating conditions of all the fluid extraction systems are then degraded.

MEILLEURE MANIERE DE REALISER L'INVENTION BEST MODE OF REALIZING THE INVENTION
L'invention concerne un registre à glissière destiné à être connecté à une canalisation d'un système d'extraction de flux de fluide tel qu'illustré par exemple de manière générale à la figure 1 , laquelle figure représente de manière purement explicative et non limitative, une installation générale de filtration de poussière. The invention relates to a slide damper intended to be connected to a pipe of a fluid flow extraction system as illustrated for example in a general manner in FIG. 1, which figure represents a purely explanatory and nonlimiting manner. , a general installation of dust filtration.
Ainsi, et tel qu'illustré à la figure 1 , l'installation de filtration de poussière 1 comporte plusieurs postes de travail notés P1 , P2, P3, ... Pn au sein desquels sont agencés un certain nombre de machines de travail générant l'émission de poussières ou résidus dans l'atmosphère et résultants d'opérations industrielles (broyage, coupe, découpe, fraisage, meulage, etc.) effectuées audits postes de travail. Thus, and as illustrated in FIG. 1, the dust filtration installation 1 comprises several workstations marked P1, P2, P3,... Pn in which a number of work machines generating a number of work machines are arranged. emission of dust or residues into the atmosphere and resulting from industrial operations (grinding, cutting, cutting, milling, grinding, etc.) carried out at work stations.
Tel qu'illustré schématiquement, chaque poste de travail P1 , P2, P3, Pn est par exemple surmonté d'une ou plusieurs canalisations 2 reliées à des ventilateurs d'extraction 3 permettant de générer un flux d'extraction assurant le transport du flux de poussières. Dans cet exemple, le flux d'extraction de fluide est donc un flux d'air chargé de poussières et/ou un mélange de fines particules véhiculées par l'air et provenant des opérations industrielles effectuées auxdits postes de travail P1 , P2, P3, Pn. As shown schematically, each workstation P1, P2, P3, Pn is for example surmounted by one or more pipes 2 connected to extraction fans 3 for generating an extraction flow ensuring the transport of the flow of dust. In this example, the fluid extraction flow is therefore a dust-laden air flow and / or a mixture of fine particles conveyed by the air and coming from the industrial operations carried out at said work stations P1, P2, P3, Pn.
Tel qu'illustré, les canalisations 2 sont connectées à une ou plusieurs canalisation(s) d'aspiration principale 4 constituant ainsi un réseau multiple de tuyauteries permettant d'acheminer le flux d'extraction chargé de poussières jusqu'à une ou plusieurs unités de filtration 5 au sein de laquelle la poussière est séparée de l'air, ou de manière plus générale, des particules en suspension dans le fluide, pour être stockées ultérieurement dans une unité de stockage 6, par exemple un silo, située en bout de chaîne et en aval de l'installation et du système d'extraction de fluide 1. As illustrated, the pipes 2 are connected to one or more main suction pipe (s) 4 thus constituting a multiple pipe network for conveying the dust-laden extraction stream to one or more water supply units. filtration 5 in which the dust is separated from the air, or more generally, particles suspended in the fluid, to be stored later in a storage unit 6, for example a silo, located at the end of the chain and downstream of the plant and fluid extraction system 1.
La figure 2 illustre une vue à plus grande échelle d'un détail de la figure 1. Sur la figure 2, on distingue les postes de travail P1 , P2, P3, P4 incluant les machines générant un flux de poussières lequel est récupéré par le biais des canalisations 2 et aspiré jusqu'à ia canalisation d'évacuation principale 4. Sur la figure 2, on distingue quatre registres à glissière 10, chaque registre à glissière 10 conforme à l'invention étant connecté à une canalisation 2 du système d'extraction de fluide 1 précédemment décrit schématiquement. La figure 3 illustre selon une vue encore plus détaillée de la figure 2, le montage de chaque registre à glissière 10 sur chacune des canalisations 2. FIG. 2 illustrates an enlarged view of a detail of FIG. 1. FIG. 2 distinguishes the workstations P1, P2, P3, P4 including the machines generating a dust flow which is recovered by the through pipelines 2 and sucked up to the main discharge pipe 4. In FIG. 2, there are four slide registers 10, each slide damper 10 according to the invention being connected to a pipe 2 of the fluid extraction system 1 previously schematically describes. FIG. 3 illustrates, according to an even more detailed view of FIG. 2, the mounting of each slide damper 10 on each of the pipes 2.
Tel qu'illustré, en particulier aux figures 3, 4 et 5, le registre à glissière 10 selon l'invention est destiné à être connecté à une canalisation 2 d'un système d'extraction de fluide 1 afin de permettre l'aspiration des flux de poussière générés à chaque poste de travail P1 , P2, P3, Pn vers le filtre 5 ou au contraire de couper l'aspiration du fluide d'extraction aux postes de travail qui ne génèrent pas de poussières. As illustrated, in particular in FIGS. 3, 4 and 5, the slide damper 10 according to the invention is intended to be connected to a pipe 2 of a fluid extraction system 1 in order to allow the suction of the dust flow generated at each workstation P1, P2, P3, Pn to the filter 5 or on the contrary to cut the aspiration of the extraction fluid to workstations that do not generate dust.
Tel qu'illustré, chaque registre à glissière 10 conforme à l'invention comporte un bâti support 11 pourvu d'un orifice 12 qui est destiné à être connecté de manière sensiblement étanche avec la canalisation 2 de manière que l'orifice 12 et la canalisation 2 soient sensiblement alignés de telle sorte que le flux d'extraction, formant le flux de fluide provenant de chaque poste de travail P1, P2, P3, Pn puisse être acheminé de la canalisation 2 dans la canalisation principale d'évacuation 4 puis dans l'ensemble du système d'extraction de fluide 1. As illustrated, each slide damper 10 according to the invention comprises a support frame 11 provided with an orifice 12 which is intended to be connected substantially sealingly with the pipe 2 so that the orifice 12 and the pipe 2 are substantially aligned so that the extraction flow, forming the flow of fluid from each workstation P1, P2, P3, Pn can be routed from the pipe 2 into the main drainage pipe 4 and then into the whole fluid extraction system 1.
Le registre à glissière 10 selon l'invention comporte également un volet 14, formé par exemple par une plaque sensiblement plane et sensiblement rigide et définissant ainsi deux faces, monté mobile sur le bâti support 11 avec une possibilité de déplacement entre une position de fermeture (figure 4) sensiblement étanche de l'orifice 2 et une position d'ouverture (figure 5) dégageant totalement l'orifice 12. The slide damper 10 according to the invention also comprises a flap 14, formed for example by a substantially flat and substantially rigid plate and thus defining two faces, mounted movably on the support frame 11 with a possibility of movement between a closed position ( FIG. 4) substantially sealed to the orifice 2 and an open position (FIG. 5) completely clearing the orifice 12.
Le registre à glissière 10 conforme à l'invention comporte également un moyen de commande et de déplacement 17 du volet 14, ledit moyen étant interposé entre le volet 14 et le bâti support 11 afin d'assurer le déplacement du volet 14 entre ses positions d'ouverture et de fermeture selon une course pré-établie. Tel qu'illustré aux figures, le moyen de commande et de déplacement 17 est avantageusement formé par un vérin de type pneumatique dont le corps principal 18 est fixé sur le bâti support 1 1 , et par exemple sur une première cornière 19 solidaire d'un bord longitudinal du bâti support 1 1 , et dont la tige d'actionnement 20 est solidaire par une extrémité 21 du volet 14, par exemple par l'intermédiaire d'une seconde cornière 22, sensiblement orthogonale à la première cornière 19 et solidaire d'une extrémité transversale du volet 14. Ce montage permet d'assurer le déplacement du volet 14 selon l'une des directions de déplacement F1 ou F2 pour atteindre, respectivement, les positions d'ouverture ou de fermeture selon une course préétablie. Selon l'invention, le registre à glissière 10 comporte un bâti support 1 1 qui est pourvu d'un système à glissière 42 (figures 6 et 7 notamment) formé par deux plaques 25, 26 métalliques, formant un logement au sein duquel le volet 14 est monté mobile, et assurant le support et ie guidage du volet 14 relativement au bâti support 1 1 avec un jeu suffisant pour assurer le coulissement du volet 14 au sein dudit système à glissière 42 entre une position d'ouverture et une position de fermeture de l'orifice 12, le volet 14 assurant l'étanchéité de la fermeture de l'orifice 12. The slide damper 10 according to the invention also comprises a means of control and displacement 17 of the flap 14, said means being interposed between the flap 14 and the support frame 11 to ensure the displacement of the flap 14 between its positions d opening and closing according to a pre-established race. As illustrated in the figures, the control and displacement means 17 is advantageously formed by a pneumatic jack whose main body 18 is fixed on the support frame 1 1, and for example on a first angle 19 integral with a longitudinal edge of the support frame 1 1, and whose actuating rod 20 is secured by one end 21 of the flap 14, for example by means of a second bracket 22, substantially orthogonal to the first bracket 19 and secured to a transverse end of the flap 14. This assembly makes it possible to ensure the displacement of the flap 14 according to one of the displacement directions F1 or F2 to reach, respectively, the open or closed positions according to a preset travel. According to the invention, the slide damper 10 comprises a support frame 1 1 which is provided with a slide system 42 (FIGS. 6 and 7 in particular) formed by two metal plates 25, 26, forming a housing in which the shutter 14 is movably mounted, and providing support and guiding the flap 14 relative to the support frame 1 1 with sufficient play to ensure the sliding of the flap 14 within said slide system 42 between an open position and a closed position of the orifice 12, the flap 14 sealing the closure of the orifice 12.
Le système à glissière 42 selon l'invention est formé par deux plaques métalliques 25, 26, préférentieliement parallèles. Elles enserrent, avec un jeu minimal, le volet 14 pour permettre son glissement au sein du logement formé par les plaques 25, 26 tout en assurant son support. La solidité et la rigidité de ces plaques leur évitent de se tordre. Cela permet de maintenir constant la forme du logement, et notamment l'espace entre les plaques 25, 26, dans lequel est inséré le volet 14, sur toute la longueur de course du volet 14. The slide system 42 according to the invention is formed by two metal plates 25, 26, preferably parallel. They grip, with minimal clearance, the flap 14 to allow its sliding within the housing formed by the plates 25, 26 while ensuring its support. The strength and rigidity of these plates prevent them from bending. This makes it possible to maintain the shape of the housing, and in particular the space between the plates 25, 26, in which the flap 14 is inserted, over the entire length of the flap 14.
Ainsi, la réalisation d'un système à glissière 42 dans lequel le volet 14 est en contact glissant direct avec le bâti support 1 1 , et ce avec un jeu minimal de fonctionnement sensiblement constant sur sensiblement la totalité de la surface du volet 14, permet d'obtenir une étanchéité du registre à glissière 10 selon l'invention en position de fermeture (figure 4) sans avoir à mettre en place un joint annulaire au niveau de l'orifice 12 comme dans l'art antérieur. Selon l'invention, le volet est ainsi supporté par le bâti support 1 sur sensiblement toute sa surface, c'est-à-dire par ses deux faces. Selon l'invention, le volet 14 est réalisé en un matériau ou recouvert d'une couche d'un matériau susceptible de permettre d'assurer à la fois le coulissement du voiet 14 ainsi que la fermeture sensiblement étanche de i'orifice 12 par le volet 14. Thus, the realization of a slide system 42 in which the flap 14 is in direct sliding contact with the support frame January 1, and with a minimum clearance substantially constant operation over substantially the entire surface of the flap 14, allows to achieve a sealing of the slide damper 10 according to the invention in the closed position (Figure 4) without having to set up an annular seal at the orifice 12 as in the prior art. According to the invention, the flap is thus supported by the support frame 1 over substantially its entire surface, that is to say by its two faces. According to the invention, the flap 14 is made of a material or covered with a layer of a material capable of ensuring both the sliding of the lens 14 as well as the substantially sealed closure of the orifice 12 by the part 14.
Ainsi, le volet 14 assure l'étanchéïté de la position de fermeture de l'orifice 12, les plaques métalliques 25, 26 ne permettant pas d'assurer cette étanchéité, leur fonction essentielle étant d'assurer le support et le guidage du voiet 14. Thus, the flap 14 ensures the sealing of the closed position of the orifice 12, the metal plates 25, 26 not making it possible to ensure this tightness, their essential function being to ensure the support and guidance of the door 14. .
Avantageusement, le volet 14 est ainsi réalisé en un matériau à base de polyéthylène ou est recouvert d'une couche externe à base de polyéthylène. Advantageously, the flap 14 is thus made of a polyethylene-based material or is covered with an outer layer based on polyethylene.
Selon une version avantageuse de l'invention, le volet 14 est constitué en PEHD, et préférentiellement de PEHD 1000 qui présente un excellent compromis entre ses propriétés de glissement, ténacité, résistance à l'usure, plage d'utilisation et innocuité. According to an advantageous version of the invention, the shutter 14 is made of HDPE, and preferably HDPE 1000 which has an excellent compromise between its sliding properties, toughness, wear resistance, range of use and safety.
Ainsi, selon l'invention, pour assurer un contact continu et glissant entre toutes les surfaces d'appui du volet 14 par ses deux faces et le système à glissière 42 du bâti support 11 ainsi qu'une bonne étanchéité en position de fermeture du volet 14, ce dernier est soit réalisé entièrement à partir d'un matériau unique constitué de polyéthylène, et de préférence de PEHD, soit recouvert d'une couche externe à base de polyéthylène voire de PEHD. Thus, according to the invention, to ensure continuous and sliding contact between all the bearing surfaces of the flap 14 by its two faces and the slide system 42 of the support frame 11 and a good seal in the closed position of the shutter 14, the latter is either made entirely from a single material consisting of polyethylene, and preferably HDPE, is covered with an outer layer based on polyethylene or HDPE.
Selon une version préférentielle de l'invention illustrée aux figures 4 à 7, le système à glissière 42 est formé par deux plaques 25, 26, respectivement supérieure et inférieure, sensiblement parallèles formant entre elles un logement d'épaisseur sensiblement équivalente à l'épaisseur du volet 14, le volet 14 étant monté mobile au sein dudit logement. According to a preferred version of the invention illustrated in FIGS. 4 to 7, the slide system 42 is formed by two plates 25, 26, respectively upper and lower, substantially parallel forming between them a housing of thickness substantially equivalent to the thickness. flap 14, the flap 14 being mounted movably within said housing.
Tel qu'illustré, les plaques 25, 26 sont de forme généralement sensiblement rectangulaire et plane dans leur partie centrale, les deux bords latéraux opposés de chaque plaque 25, 26 étant formés par deux plis longitudinaux opposés, respectivement 25A et 25B d'une part et 26A et 26B d'autre part. Les plis longitudinaux 25A, 25B d'une part, 26A, 26B d'autre part sont sensiblement plans et respectivement coplanaires tout en s'étendant dans un plan d'extension distinct, par exemple de l'ordre de quelques centimètres ou millimètres, du plan d'extension de la zone centrale de chaque plaque, 25, 26 de manière à constituer le logement pour le volet 14. As illustrated, the plates 25, 26 are of generally substantially rectangular shape and flat in their central part, the two opposite lateral edges of each plate 25, 26 being formed by two opposite longitudinal folds, respectively 25A and 25B on the one hand and 26A and 26B on the other hand. The longitudinal folds 25A, 25B on the one hand, 26A, 26B on the other hand are substantially planar and respectively coplanar while extending in a distinct extension plane, for example of the order of a few centimeters or millimeters, of the extension plane of the central zone of each plate, 25, 26 so as to constitute the housing for the flap 14.
Les plis longitudinaux 25A, 25B, 26A, 26B ont ainsi des plis dits « plis en baïonnette » obtenus par opération de frappe mécanique par exemple. Ainsi, le logement du système à 42 est formé par la superposition de deux plaques 25, 26 qui sont disposées l'une sur l'autre de façon symétrique de telle façon que leurs plis longitudinaux 25A et 25B d'une part et 26A et 26B d'autre part soient disposés l'un contre l'autre de manière à définir un logement entre les deux zones centrales 25, 26 au sein duquel le volet 14 sera supporté sur sensiblement toute sa surface tout en pouvant coulisser librement The longitudinal folds 25A, 25B, 26A, 26B thus have folds called "bayonet folds" obtained by mechanical striking operation for example. Thus, the housing of the system 42 is formed by the superposition of two plates 25, 26 which are arranged on one another symmetrically so that their longitudinal folds 25A and 25B on the one hand and 26A and 26B on the other hand are arranged against each other so as to define a housing between the two central zones 25, 26 in which the flap 14 will be supported on substantially its entire surface while being able to slide freely
Bien évidemment, le volet 14 possède des dimensions et formes adaptées pour être à même de coulisser au sein du logement sans jeu de fonctionnement tout en étant supporté sur toute sa surface de glissement. En pratique, le volet 14 est de forme sensiblement rectangulaire correspondant à la forme du logement défini par les plaques 25, 26 et présente une épaisseur sensiblement égale à celle du logement. Tel qu'illustré, le volet 14 est fixé en bout de la tige 20 de vérin, par exemple par vissage sur la cornière 22, pour qu'en position d'ouverture (figure 5) le volet 14 puisse dégager complètement l'orifice 12. Of course, the flap 14 has dimensions and shapes adapted to be able to slide within the housing without operating clearance while being supported on its entire sliding surface. In practice, the flap 14 is of substantially rectangular shape corresponding to the shape of the housing defined by the plates 25, 26 and has a thickness substantially equal to that of the housing. As illustrated, the flap 14 is fixed at the end of the rod 20 of the cylinder, for example by screwing on the bracket 22, so that in the open position (FIG. 5) the flap 14 can completely clear the orifice 12 .
Avantageusement, le volet 14 est pourvu d'une ouverture dont la surface est au moins équivalente à celle de l'orifice 12 de telle manière qu'en position d'ouverture du volet 14, l'ouverture vienne se superposer à l'orifice 12 alors qu'en position de fermeture, il est situé dans le logement entre les deux plaques 25, 26 du côté opposé à la cornière 22. Advantageously, the flap 14 is provided with an opening whose surface is at least equivalent to that of the orifice 12 so that in the open position of the flap 14, the opening comes superimposed on the orifice 12 while in the closed position, it is located in the housing between the two plates 25, 26 on the opposite side to the bracket 22.
Dans cette variante préférentielle, on dispose ainsi d'un volet 14 qui en position de fermeture est d'une longueur sensiblement équivalente à celle des plaques 25, 26 de telle sorte qu'en position de fermeture, le support du volet 14 est maximal au sein du logement ce qui favorise une bonne étanchéité. Tel qu'illustrées, les plaques 25, 26 sont assemblées entre elles par tout moyen approprié bien connu de l'homme du métier, et par exemple par visage au niveau des plis latéraux 25A, 25B, 26A, 26B avec une ou plusieurs cornières latérales 19, 19', ces dernières pouvant servir également de pièces de support et de fixation au vérin 17et aux équipements électropneumatiques de commande correspondants. In this preferred embodiment, there is thus a flap 14 which in the closed position is of a length substantially equivalent to that of the plates 25, 26 so that in the closed position, the support of the flap 14 is at maximum within the housing which promotes a good seal. As illustrated, the plates 25, 26 are assembled together by any suitable means well known to those skilled in the art, and for example by face at the side folds 25A, 25B, 26A, 26B with one or more lateral angles 19, 19 ', the latter can also serve as support and fastening parts to the cylinder 17 and corresponding electropneumatic control equipment.
Le système à glissière 42 selon l'invention illustré à la figure 6 comporte ainsi deux plaques 25, 26 qui présentent chacune deux plis latéraux respectivement 25A, 25B et 26A, 26B assemblés entre eux en opposition de sorte à fermer le logement latéralement par les plis latéraux 25A, 25B, 26A, 26B pour enserrer le volet 4 avec un jeu minimal permettant le glissement. Un tel système à glissière 42 convient particulièrement bien pour les registres à glissière de dimensions réduites ou moyennes, le diamètre de l'orifice allant généralement dans le métier du dépoussiérage, de 80 à 300 mm environ, pour lesquels il est possible de réaliser des plis latéraux par opération de frappe. En revanche, pour les registres à glissière de dimensions plus importantes, et par exemple de l'ordre de 300 à 600 mm environ il est possible de mettre en œuvre une seconde variante de réalisation illustrée à la figure 7. The slide system 42 according to the invention illustrated in FIG. 6 thus comprises two plates 25, 26 which each have two lateral folds respectively 25A, 25B and 26A, 26B assembled together in opposition so as to close the housing laterally by the folds. 25A, 25B, 26A, 26B to enclose the flap 4 with a minimum clearance for sliding. Such a slide system 42 is particularly suitable for small or medium-sized slide registers, the diameter of the orifice generally going into the dust-extraction machine, from about 80 to 300 mm, for which it is possible to produce pleats. lateral by striking operation. On the other hand, for slide dampers of larger dimensions, and for example of the order of about 300 to 600 mm, it is possible to implement a second variant embodiment illustrated in FIG. 7.
Cette variante de réalisation ne diffère de la variante illustrée à la figure 6 que par l'absence de plis latéraux 25A, 25B, 26A, 26B sur chacune des plaques 25, 26. Le système à glissière 42 est formé par deux plaques métalliques, et par exemple en acier, 25, 26 planes et sensiblement rectangulaires qui sont superposées l'une sur l'autre et assemblées entre elles par tout moyen approprié bien connu de l'homme du métier. Selon cette seconde variante de réalisation, les plaques 25, 26 sont maintenues à distance l'une de l'autre par l'intermédiaire de deux cales latérales 30, 31 pour constituer un logement dans lequel est inséré le volet 14. Les cales latérales 30,31 se présentent sous la forme générale de parallélépipèdes rectangles, formant des pièces de rattrapage de l'épaisseur du volet 14 permettant ainsi de constituer un logement pour ledit volet 14. Selon cette variante, les cales latérales 30, 31 sont d'épaisseurs sensiblement équivalentes à l'épaisseur du volet 14 et elles sont insérées latéralement entre les deux plaques 25, 26 pour fermer latéralement le logement et permettre d'insérer le volet 14 avec un jeu minimal permettant le glissement. L'assemblage des différentes pièces constitutives du registre à glissière est assuré! comme pour la variante précédente, par vissage des deux plaques 25, 26 entre elles pour constituer le bâti support 1 1 dans lequel est enfilé et monté à coulissement le volet mobile 14. This embodiment variant differs from the variant illustrated in FIG. 6 only by the absence of lateral folds 25A, 25B, 26A, 26B on each of the plates 25, 26. The slide system 42 is formed by two metal plates, and for example steel, 25, 26 flat and substantially rectangular which are superimposed on one another and assembled together by any suitable means well known to those skilled in the art. According to this second embodiment, the plates 25, 26 are kept at a distance from each other by means of two lateral shims 30, 31 to form a housing in which the flap 14 is inserted. The lateral shims 30 , 31 are in the general form of rectangular parallelepipeds, forming catch-up parts of the thickness of the flap 14 thereby forming a housing for said flap 14. According to this variant, the lateral wedges 30, 31 are of thickness substantially equivalent to the thickness of the flap 14 and they are inserted laterally between the two plates 25, 26 to close the housing laterally and to allow the flap 14 to be inserted with a minimal clearance for sliding. The assembly of the various components of the slide register is ensured ! as for the previous variant, by screwing the two plates 25, 26 between them to form the support frame 1 1 in which is slidably mounted and mounted the movable flap 14.
Selon l'invention, le bâti support est par exemple en acier et de préférence en acier galvanisé. According to the invention, the support frame is for example made of steel and preferably galvanized steel.
Tel qu'illustré, le moyen de commande et de déplacement du volet comprend au moins un vérin, de type pneumatique interposé entre le bâti support 1 1 et le volet 14, étant entendu qu'un nombre supérieur de vérins, et par exemple deux, peut bien évidemment être utilisé sans pour autant sortir du cadre de l'invention. En définitive, le registre à glissière selon l'invention est formé par : As illustrated, the means for controlling and moving the shutter comprises at least one jack, pneumatic type interposed between the support frame 1 1 and the flap 14, it being understood that a greater number of cylinders, and for example two, can obviously be used without departing from the scope of the invention. Finally, the slide damper according to the invention is formed by:
- un bâti support 1 1 comprenant deux plaques 25, 26 en acier de formes sensiblement rectangulaires et sensiblement planes, lesdites plaques comportant chacune un orifice, étant montées l'une en face de l'autre et à distance pour que les orifices soient alignés et former un logement d'épaisseur préétablie « d » ; - un volet 14 en PEHD d'épaisseur sensiblement égale à « / » et monté à coulissement libre dans le logement de sorte à pouvoir fermer de manière étanche les deux orifices dans sa position de fermeture.  - A support frame 1 1 comprising two plates 25, 26 of substantially rectangular shapes and substantially planar shapes, said plates each having an orifice, being mounted opposite one another and at a distance so that the orifices are aligned and form a housing of pre-established thickness "d"; a flap 14 made of HDPE with a thickness substantially equal to "/" and mounted to slide freely in the housing so as to be able to seal the two orifices in its closed position.
Tel qu'illustré, en particulier à la figure 3, le registre à glissière selon l'invention est monté dans une installation d'extraction de flux de fluide, et en particulier d'extraction d'air. A cette fin, le registre à glissière 10 est connecté sur chaque canalisation 2 et monté dans un plan sensiblement orthogonal à l'axe d'écoulement du fluide (correspondant à l'aspiration) dans la canalisation 2 de manière à pouvoir, selon une gestion optimisée de l'installation, obturer ou au contraire dégager la section d'évacuation de chaque canalisation. Ainsi, et en prenant l'exemple de l'installation illustrée aux figures 1 à 3 par exemple, le positionnement de chaque volet 14 dans sa position d'ouverture permet l'aspiration des poussières au niveau de chaque poste de travail P et l'évacuation par le réseau de tuyauterie principale 4 vers l'installation de fiitration 5 puis vers le silo de stockage 6. Néanmoins, et tel qu'illustré sur la figure 3 par exemple, il est possible d'optimiser la gestion de l'ensemble de l'installation et de réduire ainsi la consommation d'énergie lorsque des postes de travail sont inactifs en fermant les volets 14 de certains registres à glissière alors que d'autres, correspondant à des postes de travail en activité, sont ouverts. De manière bien connue de l'homme du métier, l'utilisation des registres à glissière est optimale lorsque chaque registre est asservi à la machine montée dans chaque poste de travail P. As illustrated, in particular in FIG. 3, the slide damper according to the invention is mounted in a fluid flow extracting installation, and in particular for extracting air. To this end, the slide damper 10 is connected to each pipe 2 and mounted in a plane substantially orthogonal to the fluid flow axis (corresponding to the suction) in the pipe 2 so as to be able, according to a management optimize the installation, plug or otherwise clear the drain section of each pipe. Thus, and taking the example of the installation illustrated in Figures 1 to 3 for example, the positioning of each flap 14 in its open position allows the suction of dust at each workstation P and the evacuation by the main pipe network 4 to the fiitration installation 5 and then to the storage silo 6. Nevertheless, and as illustrated in FIG. 3 for example, it is possible to optimize the management of the entire installation and thus reduce energy consumption when workstations are inactive by closing the flaps 14 of some slider registers while others, corresponding to active workstations, are open. In a manner well known to those skilled in the art, the use of the slide registers is optimal when each register is slaved to the machine mounted in each workstation P.
Les registres à glissière selon l'invention peuvent être utilisés dans de très nombreuses installations d'évacuation de fluide qu'il s'agisse par exemple et de manière nullement limitative, d'installations de traitement ou de transformations du bois, des céréales ou des fumés. The slide registers according to the invention can be used in a very large number of fluid evacuation installations, such as, for example and in no way limiting, treatment or transformation installations for wood, cereals or smoked.
Il s'avère en définitive que le recours à un volet mobile en polyéthylène, et en particulier en PEHD, monté dans un système à glissière permet d'obtenir un bon compromis entre les qualités de glissement, ténacité et résistance à l'usure d'une part et d'étanchéité d'autre part. It turns out that the use of a movable shutter made of polyethylene, and in particular HDPE, mounted in a sliding system makes it possible to obtain a good compromise between the sliding qualities, toughness and wear resistance of a part and sealing on the other hand.
Il s'avère également que l'utilisation d'un polyéthylène, de type PEHD1000, permet une plage d'utilisation très large, notamment dans des conditions de sollicitation thermique difficiles, et ce sans générer de phénomènes vibratoires. It also turns out that the use of a polyethylene, type HDPE1000, allows a wide range of use, especially in difficult thermal stress conditions, without generating vibration phenomena.
POSSIBILITE D'APPLICATION INDUSTRIELLE L'invention trouve son application industrielle dans la conception, la fabrication et la réalisation de dispositifs d'extraction de fluide. POSSIBILITY OF INDUSTRIAL APPLICATION The invention finds its industrial application in the design, manufacture and production of fluid extraction devices.
