On connaît un appareil pour l'obtention et la séparation des produits dans l'industrie biochimique (SU, A, 793633) comprenant une cuve dotée d'une tubulure d'amenée d'agents chimiques et d'une tubulure de sortie pour l'évacuation de la phase liquide de la suspension, un arbre creux, disposé dans la cuve et portant des pales dotées d'un élément filtrant, et un godet placé dans la tubulure de sortie et renfermant une grille de distribution de gaz réalisée sous forme d'un piston creux aux parois latérales percées de trous et montée de manière à pouvoir effectuer un mouvement de va-et-vient An apparatus is known for obtaining and separating products in the biochemical industry (SU, A, 793633) comprising a tank equipped with a tubing for supplying chemical agents and an outlet tubing for the evacuation of the liquid phase from the suspension, a hollow shaft, disposed in the tank and carrying blades with a filter element, and a bucket placed in the outlet pipe and containing a gas distribution grid made in the form of a hollow piston with side walls pierced with holes and mounted so as to be able to move back and forth

Cet appareil réunit les fonctions de trois appareils (réacteur, filtre et séchoir) Le but de cet appareil étant entre autres de protéger l'environnement contre la pollution, il est réalisé de manière à pouvoir effectuer l'obtention de la suspension, la séparation de son précipité, le séchage du précipité et sa transformation ultérieure sans qu'il soit besoin d'évacuer ce précipité de l'appareil Toutefois dans la plupart des processus de fabrication les stades de préparation de la suspension, de filtrage et de séchage du précipité doivent être suivis du déchargement du précipité de l'appareil Cela se trouve nécessaire lorsqu'il faut débarrasser les solutions des impuretés ou dans les cas o non seulement la fraction liquide du produit évacué de l'appareil représente un composant de valeur mais aussi le précipité Dans ces cas, l'appareil de ce type est inutilisable On connaît un dispositif pour la réalisation de processus physico-chimiques (Schenk, RFA, "Filtres monofeuilles") comprenant une cuve dont le fond est percé d'un trou, une chemise échangeuse de chaleur, un agitateur disposé dans la cuve dotée de tubulures d'amenée des composants de départ et d'un tuyau d'évacuation du produit fini, une cloison filtrante La cuve est réalisée de manière à pouvoir tourner autour de son axe horizontal Le fond de ce dispositif est un faux-fond déplacé à l'aide d'un système hydraulique compliqué. Ce dispositif permet de réaliser les processus d'agitation, de dissolution, d'épuration, de filtrage, d'extraction et de séchage Il permet d'obtenir aussi bien la fraction liquide du produit que sa fraction This device combines the functions of three devices (reactor, filter and dryer). The purpose of this device is among other things to protect the environment against pollution, it is realized in such a way as to obtain the suspension, the separation of its precipitate, the drying of the precipitate and its subsequent transformation without the need to evacuate this precipitate from the apparatus However in most manufacturing processes the stages of preparation of the suspension, filtration and drying of the precipitate must followed by the unloading of the precipitate from the apparatus This is necessary when it is necessary to rid the solutions of impurities or in cases where not only the liquid fraction of the product discharged from the apparatus represents a valuable component but also the precipitate. In these cases, the apparatus of this type is unusable. A device for carrying out physicochemical processes is known (Schenk, FRG , "Monofilter filters") comprising a bottom-drilled tank, a heat exchange jacket, an agitator disposed in the vessel provided with feed-in tubing of the starting components and a discharge pipe of the finished product, a filter wall The tank is made to rotate around its horizontal axis The bottom of this device is a false bottom moved using a complicated hydraulic system. This device makes it possible to carry out the agitation, dissolution, purification, filtering, extraction and drying processes. It makes it possible to obtain both the liquid fraction of the product and its fraction.
solide avec évacuation de celle-ci du dispositif. solid with evacuation thereof of the device.
Le dispositif est d'une construction compliquée Pour lui permettre de tourner autour de son axe horizontal, toutes les canalisations d'amenée et d'évacuation des produits doivent être flexibles, ce qui The device is of complicated construction To allow it to rotate about its horizontal axis, all the supply and discharge pipes of the products must be flexible, which
oblige à les réaliser en matériaux spéciaux coûteux. requires them to be made of expensive special materials.
Le dispositif connu se caractérise par des dépenses d'énergie élevées La puissance totale absorbée par les moteurs de l'agitateur, du système de basculement de la cuve et du système hydraulique de commande du fond de la cuve est de 18,5 k W pour un volume utile du The known device is characterized by high energy expenditure The total power absorbed by the agitator motors, the tilting system of the tank and the hydraulic control system of the bottom of the tank is 18.5 k W for a useful volume of the

La surface de la cloison filtrante est limitée par le diamètre du dispositif Une augmentation ou diminution de la surface de la cloison filtrante n'est possible qu'en augmentant ou en diminuant le diamètre du dispositif, ce qui, étant donné la planéité de la cloison filtrante, conduit à compliquer davantage la structure et The surface of the filtering wall is limited by the diameter of the device An increase or decrease of the surface of the filtering partition is only possible by increasing or decreasing the diameter of the device, which, given the flatness of the partition filtering, leads to further complicate the structure and
la fabrication du dispositif et en affecte le rendement. the manufacture of the device and affects its performance.
On s'est donc proposé de créer un dispositif pour la réalisation de processus physico-chimiques qui permettrait d'augmenter ou de diminuer la surface de la cloison filtrante indépendamment du diamètre de la cuve du dispositif pour la réalisation de processus physico-chimiques et de supprimer la rotation de la cuve autour de son axe horizontal, ce qui augmenterait le It has therefore been proposed to create a device for carrying out physicochemical processes which would make it possible to increase or decrease the surface of the filtering partition independently of the diameter of the vessel of the device for carrying out physico-chemical and remove the rotation of the vat around its horizontal axis, which would increase the
rendement du dispositif et en simplifierait la structure. performance of the device and simplify the structure.

(The drawing represents it in the open position) The motor 7 of the agitator 6 is started, the heating vapor is brought into the jacket 3 via the pipes 4 and 5 and the mixing of the liquid products is carried out. and solids at the expected temperature, to dissolve the solid products Once the dissolution is complete, is introduced through the tubing 8, activated carbon, to purify the solution, then stirring is continued until the purification process When the purification process is finished, the compressed gas is introduced into the tank 1 through the tubing 9 to obtain the desired overpressure. The heating medium 19 is supplied to the jacket 19 via the tubes 20 and 21. , to heat the inner space of the airlock 12 to the desired temperature equal to that of the tank 1 This temperature equalization is necessary to avoid the crystallization of the solution to the cold surfaces of the airlock 12 is closed shutter 13, turning the steering wheel 28 and the solution containing the activated carbon particles passes through the opening 26 of the shutter 13, to be filtered by the cartridges 17 The liquid fraction of the finished product (the purified solution) is removed from the device by the pipe 11 and the precipitated 16 accumulates
à la surface extérieure des cartouches 17. on the outer surface of the cartridges 17.
Pour obtenir le rendement voulu du dispositif, la surface filtrante, soit la surface des cartouches 17, peut être augmentée en augmentant le nombre et la longueur des cartouches 17 Cette augmentation du nombre de cartouches 17 et de leur longueur ne nécessite aucune To obtain the desired performance of the device, the filtering surface, ie the surface of the cartridges 17, can be increased by increasing the number and the length of the cartridges 17. This increase in the number of cartridges 17 and their length does not require any
complication de la structure du dispositif. complication of the structure of the device.
Le filtrage terminé, le précipité 16 est séché sur les cartouches 17 jusqu'au degré d'humidité prévu sous la surpression du gaz comprimé, puis la pression de la cuve 1 est relâchée pour l'égaliser à la pression atmosphérique On déplace le godet 14 à la position basse à l'aide du dispositif de commande 23 et pendant ce mouvement le dispositif 15 coupe le précipité 16 accumulé à la surface extérieure des cartouches 17 et le précipité 16 tombe dans le godet 14 En cette position basse on enlève le dispositif 15 du goulot du godet 14, on fait When the filtering is complete, the precipitate 16 is dried on the cartridges 17 to the degree of humidity predicted under the overpressure of the compressed gas, then the pressure of the tank 1 is released to equalize it at atmospheric pressure. The bucket 14 is moved. in the low position with the aid of the control device 23 and during this movement the device 15 cuts the precipitate 16 accumulated on the outer surface of the cartridges 17 and the precipitate 16 falls into the cup 14 In this low position the device 15 is removed. of the neck of the bucket 14, we make
basculer le godet 14 et le précipité en est ainsi évacué. tipping bucket 14 and the precipitate is thus evacuated.
Une fois le godet 14 vidé, on y replace le dispositif 15, le godet est réintroduit dans le sas 12 à l'aide du dispositif de commande 23 et serré contre le sas 12, en comprimant le joint 22, pour obtenir l'étanchéité du sas 12, et le cycle de fonctionnement du dispositif recommence. Dans le dispositif ainsi réalisé il n'est pas besoin de faire tourner la cuve 1 autour de son axe horizontal, ce qui permet de se passer du matériau spécial coûteux dont sont fabriquées les canalisations d'amenée et d'évacuation des produits de départ et des Once the bucket 14 emptied, it places the device 15, the bucket is reintroduced into the lock 12 with the control device 23 and pressed against the lock 12, compressing the seal 22, to obtain the seal of the sas 12, and the operating cycle of the device starts again. In the device thus produced there is no need to rotate the tank 1 about its horizontal axis, which makes it possible to dispense with the expensive special material which are manufactured the supply and discharge lines of the starting materials and of the
produits finis.Finished products.
Ainsi donc le fait de doter le dispositif d'un sas renfermant des cartouches creuses et un godet perforé avec un dispositif pour l'enlèvement du précipité permet d'améliorer nettement le rendement du dispositif, sans augmenter le diamètre de sa cuve, et d'en simplifier la structure. Thus, the fact of providing the device with an airlock containing hollow cartridges and a perforated bucket with a device for the removal of the precipitate makes it possible to considerably improve the efficiency of the device, without increasing the diameter of its vessel, and of simplify the structure.
