Abstract

A mixer with an inclined rotary vessel, characterised in that the vessel (1) comprises, on its lower bottom, a drainage opening (3) capable of being closed by a gate (12) integrally attached to the stationary frame (9) of the mixer through the intermediacy of a means (13) such as a jack, which holds it flat against the said opening during the filling and mixing stages. <IMAGE>

Description

L'invention est relative aux mélangeurs de produits divers (alimen­taires ou autres) à cuve rotative inclinée. Les mélangeurs connus du genre en question:
-possèdent, en partie haute, une ouverture servant à la fois au charge­ment et au déchargement (vidange);
-tournent dans un sens pendant le chargement et le mélange, et en sens inverse pendant la vidange;
-utilisent le godet de chargement également pour le déchargement. De telles caractéristiques induisent les inconvénients suivants: - la vidange est lente;
-le godet de chargement doit être maintenu disponible pour le décharge­ment, ce qui ne permet pas de l'utiliser à la préparation des produits correspondant à un nouveau mélange et ce pendant toute la durée des pha­ses de mélange et de vidange qui précèdent;
- le cycle préparation - chargement - mélange - vidange n'est pas continu et nécessite des arrêts fréquents avec inversion du sens de rotation de la cuve.
The invention relates to mixers of various products (food or other) with an inclined rotary tank. Known mixers of the genre in question:
-have, in the upper part, an opening used for both loading and unloading (emptying);
-turn in one direction during loading and mixing, and in the opposite direction during emptying;
-use the loading bucket also for unloading. Such characteristics induce the following drawbacks: - emptying is slow;
the loading bucket must be kept available for unloading, which does not allow it to be used for the preparation of products corresponding to a new mixture and this throughout the duration of the preceding mixing and emptying phases;
- the preparation - loading - mixing - emptying cycle is not continuous and requires frequent stops with reversal of the direction of rotation of the tank.

La présente invention a pour but de remèdier à ces divers inconvé­nients. Pour ce faire, la cuve comporte, sur son fond inférieur, une ou­verture de vidange obturable par un portillon solidaire du châssis fixe du mélangeur par l'intermèdiaire d'un moyen, tel un vérin, venant le pla­quer contre ladite ouverture pendant les phases de remplissage et de vidange.
Le portillon peut être:
- soit fixe en rotation et nécessiter, dans ce cas, un joint d'étanchéité et de frottement par rapport à la cuve;
-soit libre en rotation, gràce à l'interposition d'un roulement-butée, et être entraîné par la cuve tournante lorsqu'il est plaqué contre son ouverture de vidange.
De telles caractéristiques solutionnent les inconvénients cités précé­demment et en particulier: le godet est disponible immédiatement après le chargement, la cuve peut tourner sans le moindre arrêt et le travail complet allant de la préparation à la vidange peut se faire en continu.
The object of the present invention is to remedy these various drawbacks. To do this, the tank comprises, on its lower bottom, a drain opening which can be closed off by a door secured to the fixed frame of the mixer by means of a means, such as a jack, pressing it against said opening during the phases of filling and emptying.
The gate can be:
- either fixed in rotation and require, in this case, a seal and friction with respect to the tank;
- be free to rotate, thanks to the interposition of a bearing-stop, and be driven by the rotating tank when it is pressed against its drain opening.
Such characteristics solve the drawbacks mentioned above and in particular: the bucket is available immediately after loading, the tank can turn without the slightest stop and the complete work from preparation to emptying can be done continuously.

Les dessins annexés, donnés à titre d'exemple, et la description détaillée qui suit d'un mode préféré de l'invention, permettront de mieux comprendre celle-ci, les caractéristiques qu'elle présente et les avan­ tages qu'elle est susceptible de procurer.
Sur ces dessins:
-la figure 1 est une vue d'ensemble du mélangeur;
- la figure 2, une vue de détail du portillon, fixe en rotation, avec joint d'étanchéité et de frottement
The accompanying drawings, given by way of example, and the detailed description which follows of a preferred embodiment of the invention, will make it possible to better understand it, the characteristics it exhibits and the advantages thereof. that it is likely to provide.
In these drawings:
FIG. 1 is an overall view of the mixer;
- Figure 2, a detail view of the gate, fixed in rotation, with seal and friction

Le mélangeur à cuve rotative inclinée représenté à la figure 1 com­porte:
- une cuve cylindrique (1) à fonds bombés possèdant:
. sur son fond supérieur, une ouverture (2) de chargement centrée sur l'axe de la cuve;
. sur son fond inférieur, une ouverture de vidange (3) également centrée sur l'axe de la cuve;
. à la périphèrie extérieure, des moyens de guidage en rotation, par exemple du type anneau (4) - galet (5), et d'entraînement, par exemple du type moto-réducteur (6) - chaîne ou courroie crantée (7);
. à la périphèrie intérieure, des pâles mélangeuses (8);
- un châssis (9) supportant:
. la cuve par l'intermèdiaire des galets (5);
. le godet de chargement (10) par l'intermèdiaire d'un compas-vérin (11);
le portillon(12) par l'intermèdiaire d'un vérin (13) solidaire du châs­sis de la machine.
Un tapis (ou vis) élévateur (14) peut être placé en sortie pour récupérer les matières mélangées.
Concernant le portillon, deux versions sont possibles:

  • a) il est monté sur roulement-butée (15), selon la figure (1), et est alors entraîné en rotation par la cuve tournante lorsqu'il est plaqué contre l'ouverture de vidange de celle-ci;
  • b) il est monté solidaire de l'axe du vérin (13), selon la figure 2, et est alors fixe en rotation: un joint (16) doit être interposé entre le portillon et la cuve: il peut être solidaire soit du portillon soit de la cuve, et est réalisé dans une matière à la fois étanche et résistante°
The inclined rotary bowl mixer shown in Figure 1 includes:
- a cylindrical tank (1) with domed bottoms having:
. on its upper bottom, a loading opening (2) centered on the axis of the tank;
. on its lower bottom, a drain opening (3) also centered on the axis of the tank;
. at the outer periphery, means for guiding in rotation, for example of the ring (4) - roller (5) type, and of drive, for example of the geared motor type (6) - chain or toothed belt (7);
. on the inner periphery, mixing paddles (8);
- a chassis (9) supporting:
. the tank through the rollers (5);
. the loading bucket (10) by means of a compass-jack (11);
the gate (12) by means of a jack (13) secured to the chassis of the machine.
An elevator belt (or screw) (14) can be placed at the outlet to recover the mixed materials.
Regarding the gate, two versions are possible:
  • a) it is mounted on a thrust bearing (15), according to FIG. (1), and is then driven in rotation by the rotating tank when it is pressed against the drain opening thereof;
  • b) it is mounted integral with the axis of the jack (13), according to FIG. 2, and is then fixed in rotation: a seal (16) must be interposed between the gate and the tank: it can be integral with either the gate either from the tank, and is made of a material that is both waterproof and resistant °

Le cycle de fonctionnement d'un tel appareil peut être le suivant:

  • (1) mise en rotation de la cuve
  • (2) chargement de celle-ci par le godet
  • (3) mélange des produits à l'intérieur de la cuve
  • (4) préparation des produits à mélanger dans le godet
  • (5) vidange de la cuve
  • (6) chargement de la cuve
et le cycle recommence sans interrompre la rotation de la cuve.The operating cycle of such a device can be as follows:
  • (1) rotation of the tank
  • (2) loading it by the bucket
  • (3) mixing of the products inside the tank
  • (4) preparation of the products to be mixed in the cup
  • (5) emptying of the tank
  • (6) loading the tank
and the cycle begins again without interrupting the rotation of the tank.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté pour lequel on pourra prévoir d'autres variantes, utiliser tous types de matériaux et l'étendre à d'autres applications, sans pour cela sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment described and shown for which we can provide other variants, use all types of materials and extend it to other applications, without departing from the scope of the invention.
