    ECLUSE     OSCILLANTE   POUR   TRANSPORT     PNEUMATIQUE   
 EMI1.1 
 SOCIEIE ANOIJYME DES E1'ABLISSEMEm'S NEU 
Dans les installations de transport pneumatique ou de dépoussié- rage, on est amené à utiliser des organes permettant d'assurer   la.   
 EMI1.2 
 vidange de capacités en dépression par rapport à l'atnosphere et qui se remplissent de matières pulvérulentes ou granuleuses, ou   d' intro-   duire régulièrement dans un circuit en surpression des matières pulvérulentes ou granuleuses prises à l'atmosphère. 



   On connaît les appareils qui remplissent ce rôle par le déplace- ment d'une ou de plusieurs alvéoles qui dans leur mouvement viennent successivement se placer sous l'orifice   inférieur   de la capacité en dépression ou du dispositif d'alimentation puis se déverser à l'atmos-   phére   ou dans le circuit en pression. 



   Plus précisément, certains de ces appareils utilisent le mouve- ment alterné de deux alvéoles animés d'un mouvement d'oscillation 

 <Desc/Clms Page number 2> 

 dont la partie supérieure vient dans un   premier   tempssous un orifice d'alimentation tandis que la partie inférieure est obturée, puis dans un deuxième temps est mise en   contnunieation   avec l'atmosphère alors que la partie inférieure est ouverte permettant l'écoulement de la matière qu'elle contient. 



   Le dispositif faisant l'objet de la présente invention permet avec une disposition particulièrement simple d'assurer cette fonction. 



   Il se distingue des dispositifs précédents par le fait que c'est la matière elle-même qui commande le mouvement d'oscillation, et que l'obturation de la partie inférieure des alvéoles oscillants est réalisée par des clapets souples. 



   Une réalisation conforme à l'invention est représentée par les figures annexées. 



   La figure   1,   est une vue en coupe de   l'écluse   objet de l'invention, 
La figure 2, est une coupe transversale de cette même écluse. 



   La figure 3, est une vue de l'application de cette écluse fonc-   tionnant   en introducteur dans une enceinte en surpression. 



   Un corps fixe (1) comporte un orifice d'alimentation (2) permet- tant l'écoulement des matières dans une pièce oscillante (3). Celle-ci comporte deux alvéoles (4) et (5) séparés par une cloison 46) et pivote autour d'un axe horizontal (7) situé dans sa partie basse. 



   Chacun des alvéoles est ouvert sur une portion de sa partie supé- rieure et est fermé latéralement vers le bas par un clapet souple (8) et (9) articulé à sa partie supérieure. Un dispositif d'étanchéité (10) placé entre corps fixe (1) et pièce oscillante (3) évite des entrées ou sorties d'air excessives aussi bien en position de repos que pendant les périodes de basculement. 



   Le fonctionnement du dispositif faisant l'objet de l'invention est le suivant, la matière s'écoulant d'une capacité en dépression par   rapport à     l'atmosphère,   d'une trémie de chargement ou d'un appareil d'alimentation, remplit peu à peu l'un des alvéoles (4) dont   l'ouverture   supérieure se trouve slors sous l'orifice (2) tandis que le clapet 

 <Desc/Clms Page number 3> 

 inférieur   (8)   se   trouve     ferme   par son libre mouvement aidé de la différence de pression régnant entre ses deux faces. 



   Lorsque cet alvéole est   suffisanment   plein, le poids de la   matière   le fait basculer et ceci d'autant plus que le mouvaient est amorcé, Le   clapot   (9) se referme, L'alvéole (5) vient se placer sous   l'orifice   d'alimentation, tandis que l'orifice supérieur de l'alvéole (4) se met à l'atmosphère ou à une   surpression   égale   à   celle existant au-dessous de   l'appareil.   Le clapet (8)   libère   de la pression s'ouvre par son mouvement   naturel   aidé de la poussée de la matière et celle- ci s'écoule vers le bas.

    OSCILLATING LOCK FOR PNEUMATIC TRANSPORT

 ANOIJYME SOCIETY OF E1'ABLISSEMEm'S NEU
In pneumatic conveying or dust removal installations, it is necessary to use devices making it possible to ensure the.
 EMI1.2
 emptying of capacities in depression with respect to the atmosphere and which are filled with powdery or granular materials, or to introduce regularly into a circuit under pressure powdery or granular materials taken from the atmosphere.



   Apparatuses are known which fulfill this role by moving one or more cells which, in their movement, come successively to place themselves under the lower orifice of the vacuum capacity or of the supply device and then discharge into the chamber. atmosphere or in the pressure circuit.



   More precisely, some of these devices use the alternating movement of two cells animated by an oscillating movement.

 <Desc / Clms Page number 2>

 the upper part of which comes firstly under a supply port while the lower part is closed, then in a second step is put in contnunieation with the atmosphere while the lower part is open allowing the flow of the material which 'it contains.



   The device forming the subject of the present invention makes it possible, with a particularly simple arrangement, to perform this function.



   It differs from the previous devices by the fact that it is the material itself which controls the oscillating movement, and that the closure of the lower part of the oscillating cells is achieved by flexible valves.



   An embodiment according to the invention is represented by the appended figures.



   Figure 1 is a sectional view of the lock object of the invention,
Figure 2 is a cross section of the same lock.



   FIG. 3 is a view of the application of this lock operating as an introducer in an overpressure chamber.



   A fixed body (1) has a supply orifice (2) allowing the flow of materials in an oscillating part (3). This comprises two cells (4) and (5) separated by a partition 46) and pivots about a horizontal axis (7) located in its lower part.



   Each of the cells is open over a portion of its upper part and is closed laterally downwards by a flexible valve (8) and (9) articulated at its upper part. A sealing device (10) placed between the fixed body (1) and the oscillating part (3) prevents excessive inflows or outflows of air both in the rest position and during the tilting periods.



   The operation of the device which is the object of the invention is as follows, the material flowing from a capacity at negative pressure with respect to the atmosphere, from a loading hopper or from a supply apparatus, fills little by little one of the cells (4), the upper opening of which is located under the orifice (2) while the valve

 <Desc / Clms Page number 3>

 lower (8) is closed by its free movement aided by the pressure difference between its two faces.



   When this cell is sufficiently full, the weight of the material causes it to tip over and this all the more so as it is started to move, The chop (9) closes, The cell (5) is placed under the orifice of supply, while the upper opening of the cell (4) is vented to the atmosphere or to an overpressure equal to that existing below the device. The valve (8) releases the pressure opens by its natural movement assisted by the thrust of the material and the latter flows downwards.

RESUME Ecluse comportant deux alvéoles fixes, l'un par rapport à l'autre) rais pouvant basculer autour d'un axe horizontal caractérise par les points suivants, séparément ou en combinaison. SUMMARY Lock comprising two fixed cells, one in relation to the other) spokes capable of tilting around a horizontal axis characterized by the following points, separately or in combination. (I) Chaque alvéole comporte deux ouvertures dont l'un est muni d'un clapet battant souple et l'autre vient se placer du fait du bascu- lement soit devant un orifice par lequel peut passer la matière à évacuer, soit sur le coté. (I) Each cell has two openings, one of which is fitted with a flexible flapping valve and the other is placed due to the tilting either in front of an orifice through which the material to be removed can pass, or on the side. . (2) L'axe de rotation se trouve au-dessous du centre de gravite de la pièce oscillante. (2) The axis of rotation is below the center of gravity of the oscillating part. (3) Le mouvement de la pièce oscillante est produit par le poids de la matière éclusée remplissant un alvéole. (3) The movement of the oscillating part is produced by the weight of the sluice material filling a cell. (4) L'étanchéité à la partie supérieure est réalisée par joints souples. (4) The upper part is sealed by flexible gaskets. (5) Un dispositif de mise à la pression inférieure assure l'égalisation des pressions dvant l'ouverture des clapets. (5) A lower pressure device ensures the equalization of the pressures before the opening of the valves.
