Abstract

A motorised extractor feeder (7) draws material in bulk from a silo (9) through a safety valve (10). The material passes through an entry valve (11) and a sleeve (12) into a storage hopper (5) which may be fixed or rotatable about an horizontal axis. The storing hopper (5) is supported by weight sensors (4) which rest on a base (1) carried by a chassis (2). The material is evacuated from the storing hopper (5) for transportation through an exit valve (13) and a sleeve by an extractor whose speed is adjustable. USE/ADVANTAGE - For food, chemical or heavy industries. Equipment can handle very hot finely divided, granular or recycled materials accurately.

Description

DISPOSITIF DE MANUTENTION DE PRODUITS EN VRAC
PAR PESAGE
La présente invention a pour objet un dispositif de manutention de produits en vrac par pesage.DEVICE FOR HANDLING BULK PRODUCTS
BY WEIGHING
The present invention relates to a device for handling bulk products by weighing.

I1 est destiné à permettre le dosage de produits en vrac ou granuleux dans des installations dont les caractéristiques permettent des sequences de remplissage entre deux phases dlalimentation continue telles que produit d'ajouts, récyclés, ou à haute température, en particulier dans les industries lourdes, alimentaires, chimiques. It is intended to allow the dosing of loose or granular products in installations whose characteristics allow filling sequences between two continuous feeding phases such as additives, recycled, or at high temperature, in particular in heavy industries, food, chemical.

Les installations de ce type realisées à ce jour, soit comportent une chaîne de manutention continue sans pesage ce qui conduit à des gaspillages par imprecision ou à des erreurs de formule, soit des doseurs à bande inapplicables dans les produits à plus de 250 , ou dont la finesse est inférieure à quelques niicrons. Soit enfin fonctionnent en perte de poids en regulation continue, ce qui entraîne des frais excessifs de maind'oeuvre et dtimmobilisation.  Installations of this type carried out to date, either include a continuous handling chain without weighing which leads to wastage by imprecision or to errors in formula, or belt dosers inapplicable in products with more than 250, or whose the fineness is less than a few niicrons. Or finally operate in weight loss with continuous regulation, which leads to excessive labor and immobilization costs.

Le dispositif selon la présente invention supprime tous ces inconvenients. En effet, il permet de charger une trémie en un temps très cour à tres grand débit. De surcroît, dans le cas de produit granuleux à forte température la trémie tampon du système est rotative avec un moteur d'entraînement, ce qui évite de placer un extracteur pour la vider. Cette opération étant faite par le simple demi tour d'une benne rottive.  The device according to the present invention eliminates all these drawbacks. Indeed, it allows to load a hopper in a very short time at very high flow. In addition, in the case of granular product at high temperature, the buffer hopper of the system is rotatable with a drive motor, which avoids placing an extractor to empty it. This operation is done by the simple U-turn of a dump body.

Le dispositif est constitué par la combinaison, d'une part, d'un châssis dont le rôle est de supporter une trémie de stockage fixe ou rotative avec extracteur alimentateur solidaire du silo d'alimentation et, d'autre part, d'une embase fixe solidaire dudit châssis portant sur laquelle reposent des capteurs de pesage portant ladite trémie de stockage, celle-ci, dans le cas où elle est fixe, pouvant être isolée en amont et en aval par un système à vannes et manchettes souples, dans le système à trémie rotative, l'arrêt de l'extracteur ou de la rotation suffisant à couper l'alimentation ou la vidange du produit. The device consists of the combination, on the one hand, of a chassis whose role is to support a fixed or rotary storage hopper with feeder extractor secured to the feed silo and, on the other hand, of a base fixed integral with said chassis on which rest load cells carrying said storage hopper, the latter, in the case where it is fixed, which can be isolated upstream and downstream by a system with valves and flexible sleeves, in the system with rotary hopper, the stop of the extractor or rotation sufficient to cut off the supply or the draining of the product.

Sur les dessins schématiques annexés, donné à titre d'exemple non limitatif d'une des formes de réalisation de ltobjet de l'invention:
la figure 1 est une vue latérale en élévation du dispositif à trémie fixe avec extracteur,
la figure 2 représente dans les mêmes conditions, et suivant la fleche B de la figure 3, le dispositif à trémie rotative,
et la figure 3 est une coupe verticale axiale partielle suivant les flèches A-A de la figure 2.In the appended schematic drawings, given by way of nonlimiting example of one of the embodiments of the object of the invention:
FIG. 1 is a side elevation view of the fixed hopper device with extractor,
FIG. 2 represents, under the same conditions, and according to arrow B in FIG. 3, the device with a rotary hopper,
and FIG. 3 is a partial axial vertical section along the arrows AA of FIG. 2.

Le dispositif, figures 1 à 3, est constitue d'une embase 1 fixe reposant sur un châssis 2, 3 et supportant, par l'intermédiaire de capteurs 4 de pesage une trémie de stockage fixe 5 ou rotative 6 suivant l'application requise, dans laquelle débite un extracteur alimentateur 7, 8 solidaire du silo de stockage 9, et adapté aux caractéristiques du produit à doser. The device, FIGS. 1 to 3, consists of a fixed base 1 resting on a chassis 2, 3 and supporting, by means of weighing sensors 4 a fixed 5 or rotary 6 storage hopper according to the required application, in which delivers a feed extractor 7, 8 secured to the storage silo 9, and adapted to the characteristics of the product to be dosed.

La figure 1 montre le dispositif à trémie fixe 5 avec registre de sécurité 10, extracteur alimenteur 7 motorisé, vanne d'alimentation il à deux positions et manchette souple 12. La tremie pesee par compression des capteurs 4 s'appuyant sur L'embase 1. Une vanne de sortie 13 à deux positions et manchette souple 14 s'ouvre en fonction de la cadence choisie pour évacuer le produit par l'extracteur pour transport 15, dans le temps nécessaire pour respecter le débit. FIG. 1 shows the fixed hopper device 5 with safety register 10, motorized extractor feeder 7, supply valve there in two positions and flexible sleeve 12. The hopper weighed by compression of the sensors 4 based on the base 1 An outlet valve 13 with two positions and flexible sleeve 14 opens according to the rate chosen to evacuate the product by the extractor for transport 15, in the time necessary to respect the flow rate.

Ce système à double vanne et manchettes souples permet d'isoler la trémie pesée en amont et en aval. This double valve system with flexible sleeves allows the weighing hopper to be isolated upstream and downstream.

Les figures 2 et 3 montrent le dispositif avec trémie rotative 6 avec une entrée latérale 8 de l'alimentateur qui peut être supérieure 8'. Le châssis 2 est constitué d'un capotage à l'intérieur duquel se trouve la benne rotative 6 et supportant le moteur 16 d'entraînement de cette dernière, l'accouplement 17, les paliers 18 et les arbres 19, Cet ensemble, maintenu par des parallélogrammes déformables 20 pour éviter tout déplacement autre que vertical, supporte la benne et sous l'effet du poids peut tirer sur les capteurs de pesage 4 en se déplaçant dans deux joints labyrinthe 21 dont le jeu suffit à éviter tout frottement. Figures 2 and 3 show the device with rotary hopper 6 with a side inlet 8 of the feeder which can be upper 8 '. The chassis 2 consists of a cover inside of which is the rotary bucket 6 and supporting the motor 16 for driving the latter, the coupling 17, the bearings 18 and the shafts 19, This assembly, maintained by deformable parallelograms 20 to avoid any movement other than vertical, supports the bucket and under the effect of the weight can pull on the load cells 4 by moving in two labyrinth seals 21 whose play is sufficient to avoid any friction.

L'arret de l'extracteur ou L'arrêt de la rotation suffit à couper 1'alimentation ou la vidange du produit. Stopping the extractor or stopping the rotation is enough to cut off the supply or the emptying of the product.

Coe dans le système fixe, une charge non précisément determinee est placee dans la trémie ou benne, pesée de facon p---ecise et délivrée dans le temps voulu pour obtenir le débit souhaité. As in the fixed system, a load which is not precisely determined is placed in the hopper or bucket, weighed in a precise manner and delivered in the time required to obtain the desired flow rate.

Donc la tremie remplie, pesée par les capteurs 4 avec une grande précision, la vidange se fera dans le temps requis pour obtenir un débit donne. Ce systeme ne nécessite donc pas un poids prédétermine fixe. Il suffit de constater le poids obtenu à l'arrêt pour, en fonction du temps, décider du moment de la marche de l'extracteur 7 ou de la rotation de la tremie 6. Ainsi dans une capacité fixée, on obtient précisément un poids variable que l'on decharge au bout d'un temps variable fonction de ce poids pour obtenir un débit constant. So the hopper filled, weighed by the sensors 4 with great precision, the emptying will be done in the time required to obtain a given flow. This system therefore does not require a fixed predetermined weight. It suffices to note the weight obtained at standstill in order, as a function of time, to decide when the extractor 7 will run or when the hopper will rotate 6. Thus in a fixed capacity, a variable weight is precisely obtained that we discharge after a variable time depending on this weight to obtain a constant flow.

Le positionnement des divers élements constitutifs aonne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
