Description

DESCRIPTION
La présente invention concerne un caisson de filtration, du genre, comprenant un receptacle de forme parrallelipépidique avec deux ouvertures sur des faces opposées, dont l'une forme ouverture d'admission de gaz a filtrer et l'autre ouverture pour l'évacuation du gaz filtré, avec, entre lesdites ouvertures, un panneau latéral amovible pour la mise en place ou le retrait d'une cellule filtrante adaptée à venir en appui étanche par un joint circonscrivant une des dites ouvertures, et des moyens de verrouillage de ladite cellule filtrante en appui serré sur ledit joint incorporant une barre déplaçable de mise en pression prenant elle-meire appui sur des organes d'ancrage du caisson par l'intermédiaire de moyens d'écartement à commande manuelle de ladite barre par rapport auxdits organes d'ancrage.
DESCRIPTION
The present invention relates to a filtration box, of the type, comprising a receptacle of parallelepipidic shape with two openings on opposite faces, one of which forms an opening for admission of gas to be filtered and the other opening for the evacuation of gas. filtered, with, between said openings, a removable side panel for fitting or removing a filter cell adapted to come into leaktight support by a seal circumscribing one of said openings, and means for locking said filter cell in tight support on said seal incorporating a displaceable bar for pressurizing itself taking support on anchoring members of the box by means of spacers with manual control of said bar relative to said anchoring members.

Les moyens d'écartement à commande manuelle sont généralement constitués de vis de pression et l'opération de serrage d'une cellule filtrante s'avère longue. Or dans un certain nombre d'applications de ces caissons de filtration, on a affaire à des batteries de caissons filtrants en très grand nombre, si bien que l'opération de changement d'un filtre usagé par un filtre neuf devient reiativement coûteuse et fastidieuse. The manually controlled spacing means generally consist of pressure screws and the tightening operation of a filter cell is long. However, in a certain number of applications of these filter boxes, we are dealing with batteries of filter boxes in very large numbers, so that the operation of changing a used filter with a new filter becomes reiatively expensive and tedious .

L'objectif de la présente invention est de promouvoir un système de verrouillage en position opératoire du panneau filtrant, qui soit de mise en oeuvre très rapide et cet objectif est atteint en réalisant les moyens d'écartement à commande manuelle sous forme de cames à levier de commande. The objective of the present invention is to promote a locking system in the operating position of the filter panel, which is very quick to implement and this objective is achieved by producing the manually controlled spacing means in the form of lever cams. control.

Selon une forme de réalisation, où l'organe d'ancrage est un barreau d'ancrage médian solidaire du caisson, au travers duquel sont montées à coulissement des tiges de guidage solidaires de la barre d'appui déplaçable, on prévoit qu'un plateau-support de cames, monté à coulissement libre sur desdites tiges de guidage, est maintenu en position axiale fixe par une plaque de retenue solidaire du barreau fixe, lesdites cames agissant par des rampes de came contre des pièces transversales d'actionnement chacune solidaire d'une tige de guidage, contre l'action d'un ressort de compression entre le barreau fixe et la pièce d'actionnement. According to one embodiment, where the anchoring member is a median anchoring bar integral with the box, through which are slidably mounted guide rods integral with the movable support bar, a tray is provided -support for cams, mounted to slide freely on said guide rods, is held in a fixed axial position by a retaining plate secured to the fixed bar, said cams acting by cam ramps against transverse actuating parts each secured to a guide rod, against the action of a compression spring between the fixed bar and the actuating part.

De préférence, chaque pièce d'actionnement coopère avec deux cames d'un plateau actionné par un levier et l'angle d'actionnement est de l'ordre d'un quart de tour.  Preferably, each actuation part cooperates with two cams of a plate actuated by a lever and the actuation angle is of the order of a quarter of a turn.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui suit, à titre d'exemple, en référence aux dessins annexés, dans lesquels - la figure 1 est une vue en perspective avec arrachement partiel d'un caisson selon l'invention ; - les figures 2 et 3 sont des vues partielles en élévation de face et de profil de ce meme caisson - la figure 4 est une vue en coupe transversale selon les flèches BB de la figure 2. The characteristics and advantages of the invention will become apparent from the following description, by way of example, with reference to the appended drawings, in which - Figure 1 is a perspective view with partial cutaway of a box according to the invention; FIGS. 2 and 3 are partial front and side elevation views of this same box - FIG. 4 is a cross-sectional view along the arrows BB of FIG. 2.

- la figure 5 est une vue en perspective partiellement éclatée du système de mise sous pression.- Figure 5 is a partially exploded perspective view of the pressurization system.

En se référant aux dessins annexés, un caisson de filtration est de forme parallélépipédique, avec une paroi de fond 3 ayant une large ouverture 4 pour l'admission d'un gaz å filtrer, cette ouverture 4 étant circonscrite par un joint annulaire, et, en face de celle-ci, une paroi latérale incorporant une ouverture 5 pour l'évacuation du gaz filtré. Referring to the appended drawings, a filtration box is of rectangular shape, with a bottom wall 3 having a wide opening 4 for the admission of a gas to be filtered, this opening 4 being circumscribed by an annular seal, and, opposite this, a side wall incorporating an opening 5 for the evacuation of the filtered gas.

Entre ces deux ouvertures 4 et 5, est prévue une paroi latérale rétractable 6 qui permet la mise en place ou le retrait d'une cellule filtrante 2, qui est appliquée de façon étanche contre le joint de l'ouverture 4 par des moyens de verrouillage accessibles manuellement au travers de l'ouverture d'évacuation latérale après démontage de la porte 6.Between these two openings 4 and 5 is provided a retractable side wall 6 which allows the installation or removal of a filter cell 2, which is applied sealingly against the seal of the opening 4 by locking means manually accessible through the side discharge opening after removing the door 6.

Ces moyens de verrouillage comprennent un organe ou barreau d'ancrage 10 solidaire en position médiane à l'intérieur du caisson 1, avec fixation par boulonnages haut 11 et bas 12 sur des parois inférieure et supérieure 13 et 14 du caisson 1. Ce barreau d'ancrage 10 d'une part sert à la fixation de deux plateaux d'ancrage 25 et 25', qui sont fixés à distance du barreau 10 par des tirants 26 et 27, d'autre part présente deux ouvertures pour le passage coulissant de tiges 23, 23' solidaires chacune à une extrémité en haut et bas d'une barre de pression verticale 22 et, à l'autre extrémité, coulissant librement chacune au travers d'une plaque d'ancrage 25, 25' respectivement. These locking means comprise an anchoring member or bar 10 fixed in the middle position inside the box 1, with fixing by bolts top 11 and bottom 12 on the bottom and top walls 13 and 14 of the box 1. This bar d 'anchor 10 on the one hand is used for fixing two anchor plates 25 and 25', which are fixed at a distance from the bar 10 by tie rods 26 and 27, on the other hand has two openings for the sliding passage of rods 23, 23 'each secured to one end at the top and bottom of a vertical pressure bar 22 and, at the other end, each sliding freely through an anchor plate 25, 25' respectively.

Sur chacune de ces tiges 23, 23' est monté à coulissement libre un plateau 28 à cames 30, 31, solidaire d'un levier de manoeuvre 29,29' le plateau 28 étant constamment en appui contre la plaque d'ancrage 25 sous l'action d'un ressort de compression 34. On each of these rods 23, 23 ′ is mounted with free sliding a plate 28 with cams 30, 31, integral with an operating lever 29, 29 ′ the plate 28 being constantly in abutment against the anchoring plate 25 under the action of a compression spring 34.

Les cames 30 et 31 sont des parties cylindriques coaxiales à la tige 23, s'étendant à la périphérie du plateau circulaire 28, sous forme de rampes circulaires ayant une hauteur axiale progressivement croissante depuis une dimension nulle en 32, 32' jusqu'à une dimension maximale en 33, 33' chacune sur une extension angulaire de l'ordre de 900. The cams 30 and 31 are cylindrical parts coaxial with the rod 23, extending at the periphery of the circular plate 28, in the form of circular ramps having an axial height progressively increasing from a zero dimension in 32, 32 'to a maximum dimension in 33, 33 'each over an angular extension of the order of 900.

Le ressort 34 exerce son effet de pression sur les cames 30 et 31 par l'action d'une clavette 32 transversalement solidaire de la tige 23 qui elle-meme est bloquée en rotation. The spring 34 exerts its pressure effect on the cams 30 and 31 by the action of a key 32 transversely secured to the rod 23 which itself is locked in rotation.

En opération, dans la position rétractée du levier 29 (position qui est celle représentée à la figure 5), les cames 30 et 31 sont placées en des positions angulaires où la clavette 32 est en position de desserage, c'est-à-dire en 32,32', avec le ressort 34 en état allongé. In operation, in the retracted position of the lever 29 (position which is that shown in FIG. 5), the cams 30 and 31 are placed in angular positions where the key 32 is in the loosening position, that is to say in 32.32 ′, with the spring 34 in an elongated state.

Une fois la cellule filtrante 2 mis en place, on manoeuvre les leviers 29,29' selon les flèches F,. ce qui a pour effet de faire agir les rampes des cames 30,31 sur les deux extrémités de la clavette 32 en la repoussant, ainsi que la tige 23, dans le sens de la flèche F' avec compression du ressort 34. Ce déplacement des tiges 23 (en bas) et 23' (en haut), qui se fait avantageusement par action simultanée sur les leviers bas 29 et haut 29', a pour effet de repousser le barreau de pression 22 dans le sens F', ce qui applique fermement la cellule filtrante 2 contre le joint de l'ouverture 4. Après quoi. on remet en place la porte 6 et le caisson 1 est opératif.Once the filter cell 2 is in place, the levers 29, 29 ′ are operated according to the arrows F,. which has the effect of causing the ramps of the cams 30,31 to act on the two ends of the key 32 by pushing it back, as well as the rod 23, in the direction of the arrow F ′ with compression of the spring 34. This displacement of the rods 23 (bottom) and 23 '(top), which is advantageously done by simultaneous action on the bottom levers 29 and top 29', has the effect of pushing the pressure bar 22 in the direction F ', which applies firmly the filter cell 2 against the seal of the opening 4. After which. the door 6 is replaced and the box 1 is operational.

L'invention n'ait pas limitée à la forme de réalisation décrite et représentée. Elle s'applique en particulier aux caissons à plusieurs alvéoles chacune recevant un panneau filtrant, le verrouillage pouvant alors comprendre un moyen de commande unique des différents leviers de cames.  The invention is not limited to the embodiment described and shown. It applies in particular to boxes with several cells each receiving a filtering panel, the locking then being able to comprise a single control means for the different cam levers.
