Abstract
Description
La présente invention est relative à un appareillage destiné à permettre de réaliser de façon automatique une pluralité d'opérations d'analyses et/ou de mesures de caractéristiques physico-chimiques sur des solutions ou des suspensions. The present invention relates to an apparatus intended to make it possible to automatically carry out a plurality of analysis and / or measurement operations of physicochemical characteristics on solutions or suspensions.
Cet appareillage est constitué par un gobelet ouvert à sa partie supérieure et comportant un fond concave muni en son centre d'un orifice muni d'une vanne de vidange commandée à distance, ce gobelet comportant au voisinage de son bord supérieur un orifice de vidange par trop-plein et étant surmonté par une structure destinée à servir de support à des appareils divers tels qu'agitateur, capteurs et canalisations d'alimentation. This apparatus consists of a cup open at its upper part and comprising a concave bottom provided in its center with an orifice provided with a remotely controlled drain valve, this cup comprising in the vicinity of its upper edge a drain orifice by overflow and being surmounted by a structure intended to serve as a support for various devices such as agitator, sensors and supply lines.
De préférence, cette structure porteuse est constituée par un couvercle fermant de façon étanche l'ouvert ture. Preferably, this support structure is constituted by a cover sealingly closing the opening.
A titre d'exemple non limitatif et pour faciliter la compréhension de l'invention, on a représenté au dessin annexé une vue schématique en coupe partielle d'un exemple de réalisation dé l'invention. By way of nonlimiting example and to facilitate understanding of the invention, there is shown in the accompanying drawing a schematic view in partial section of an exemplary embodiment of the invention.
En se reportant à cette figure, on voit que cet appareillage est constitué par un pot 1 ouvert à sa partie supérieure 2 et comportant un fond concave 3 percé en son centre par une ouverture 4. Cette ouverture 4 est obturée par un clapet 5 commandé par un piston pneumatique 6 (ou un solénoide),la tige 7 du clapet et le mécanisme de commande étant protégés par un soufflet 8. Ce clapet fait communiquer l'ouverture 4 avec une canalisation de vidange 9. Referring to this figure, it can be seen that this apparatus is constituted by a pot 1 open at its upper part 2 and comprising a concave bottom 3 pierced in its center by an opening 4. This opening 4 is closed by a valve 5 controlled by a pneumatic piston 6 (or a solenoid), the rod 7 of the valve and the control mechanism being protected by a bellows 8. This valve communicates the opening 4 with a drain pipe 9.
A proximité de son ouverture supérieure 2, le pot l est muni d'un orifice de trop plein 10 raccordé à un bec verseur 11. On peut prévoir plusieurs orifices tels que 10, chacun pouvant avoir un bec verseur. Near its upper opening 2, the pot 1 is provided with an overflow hole 10 connected to a pouring spout 11. Several orifices such as 10 can be provided, each of which may have a pouring spout.
Dans l'exemple représenté, la structure disposée au-dessus de l'ouverture 2 du pot 1 est constituée par un couvercle 12. Ce couvercle 12 est percé d'un orifice central 13 dans lequel est placé un manchon 14 recevant une douille 15 portant un agitateur 17 entraîné par exemple par un câble sous gaine 16. Le couvercle 12 comporte en plus une pluralité d'orifices munis de douilles 18 ou 19 destinées à permettre le passage à travers le couvercle 12 de capteurs tels par exemple que des électrodes 20 ou de tuyaux tels que 21 pour l'introduction de liquides dans le pot 1. In the example shown, the structure disposed above the opening 2 of the pot 1 is constituted by a cover 12. This cover 12 is pierced with a central orifice 13 in which is placed a sleeve 14 receiving a socket 15 carrying an agitator 17 driven for example by a sheathed cable 16. The cover 12 further comprises a plurality of orifices provided with sockets 18 or 19 intended to allow the passage through the cover 12 of sensors such as for example electrodes 20 or pipes such as 21 for the introduction of liquids into the pot 1.
De préférence, le couvercle 12 est maintenu serré de façon étanche sur l'ouverture 2 du pot l par une pluralité de tirants 22 fixés à une plaque de base 23 maintenant le corps de la valve 5-6 serré contre l'orifice 4 du fond 3. Preferably, the cover 12 is held tightly sealed on the opening 2 of the pot l by a plurality of tie rods 22 fixed to a base plate 23 holding the body of the valve 5-6 tight against the orifice 4 of the bottom 3.
Bien que cela ne soit pas représenté, les tirants 22 peuvent, lorsque le pot 1 est en verre, servir de support d'un côté à une source de photons,et de l'autre côté à un détecteur adéquat, ce qui permet par exemple de procéder à la mesure des variations des caractéristiques du faisceau incident résultant de la traversée de la solution ou suspension se trouvant dans le pot 1. Although not shown, the tie rods 22 can, when the pot 1 is made of glass, serve as a support on one side for a photon source, and on the other side for a suitable detector, which allows for example to measure the variations in the characteristics of the incident beam resulting from the passage of the solution or suspension in the pot 1.
Le couvercle 12 peut comporter un orifice portant un entonnoir. The cover 12 may include an orifice carrying a funnel.
Ainsi. on Deut. sans intervention manuelle int.ro - (solida ou liauide) duire un produit à analyser ou doser/dans le pot 1 ; puis un solvant ou réactif liquide, par la canalisation 21 ; puis homogénéSser la solution ou suspension au moyen de l'agitateur 17 ; procéder à une mesure de pH par exemple au moyen d'électrodes telles que 20 ou toute autre-mesure électrique ; procéder à une mesure de rayonnement telle par exemple que diffraction lumineuse ou variation de transparence du bain ; et, les différentes mesures ayant été réalisées, vidanger le pot par la vanne 5 et la nettoyer en introduisant un liquide de lavage par une conduite telle que 21, évacuer alors le liquide de lavage par la valve 5 et recommencer un cycle de mesures et/ou d'analyses. So. we Deut. without manual intervention int.ro - (solida or liauide) add a product to be analyzed or dose / in jar 1; then a solvent or liquid reagent, via line 21; then homogenize the solution or suspension by means of the agitator 17; carry out a pH measurement for example by means of electrodes such as 20 or any other electrical measurement; carry out a measurement of radiation such as for example light diffraction or variation of transparency of the bath; and, the various measurements having been carried out, empty the pot by the valve 5 and clean it by introducing a washing liquid through a line such as 21, then evacuate the washing liquid by the valve 5 and repeat a measurement cycle and / or analyzes.
Cet appareillage permet donc de réaliser de façon entièrement automatique des cycles répétitifs de mesures et ou d'analyses commandés par une centrale telle par exemple qu'un micro-ordinateur. This apparatus therefore makes it possible to carry out repetitive cycles of measurements and or analyzes controlled entirely by a central unit such as, for example, a microcomputer.
Selon un exemple non limitatif, les tirants 22 peuvent porter d'un côté du pot 1 une source lumineuse et de l'autre côté du pot 1 une cellule photo-électrique, la mesure réalisée étant une mesure de variation de l'intensité lumineuse traversant le liquide en suspension ou en solution. According to a nonlimiting example, the tie rods 22 can carry a light source on one side of the pot 1 and a photoelectric cell on the other side of the pot 1, the measurement carried out being a measurement of variation of the light intensity passing through the liquid in suspension or in solution.
De même, bien que cela ne soit pas représenté, l'appareillage peut être mis à l'intérieur d'une enceinte thermostatique reliée à une source de chaleur ou une source de froid, de sorte que l'on puisse déterminer à volonté la température de la solution ou suspension. Likewise, although this is not shown, the apparatus can be placed inside a thermostatic enclosure connected to a heat source or a cold source, so that the temperature can be determined at will. of the solution or suspension.
