Abstract

The metering and agitating device for sandy material having a tendency to compact e.g. in a compressed air sand blasting machine, includes an agitator (1) having a thin profile for assuring necessary agitation for eliminating compaction of the aggregate. The device also includes a metallic washer forming two fins (2) that serve to meter the aggregate. The rotating pneumatically driven axle of the metering device and the agitator are fixed to an axis (3).

Description

La présente invention concerne un dispositif de dosage et de brassage pourThe present invention relates to a metering and stirring device for

les sableuses projetant des agrégats souples ou, ayant tendance à former des zones de compactage, et difficile à doser. Le dosage est traditionnellement fait par une vis sans fin et un agitateur pneumatique, ne permettant pas un flux régulier des agrégats dans le flux d'air comprimé; le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte en effet une première caractéristique, un brasseur (1) solidaire de l'axe rotatif ( entraîné par un moteur pneumatique et une chaîne de transmission, ce brasseur permet en rotation de "déséquibrer " les zones de compactage qui se forment à fur et mesure de l'écoulement des agrégats de la cuve  sandblasters projecting flexible aggregates or, tending to form areas of compaction, and difficult to dose. The dosing is traditionally done by a worm screw and a pneumatic agitator, not allowing a regular flow of the aggregates in the flow of compressed air; the device according to the invention overcomes this drawback. It has in fact a first characteristic, a stirrer (1) integral with the rotary axis (driven by a pneumatic motor and a transmission chain, this stirrer allows in rotation to "unbalance" the compaction zones which are formed as and measurement of tank aggregate flow

(4) vers le flux d'air comprimé.(4) to the compressed air flow.

Et la seconde caractéristique est le doseur, constitué d'une rondelle métallique découpée pour former deux ergots (2) toujours solidaire de l'axe de rotation. Les essais réalisés grâce au nouveau dispositif montrent que le débit maximum a été multiplié par 1,4 et que l'autonomie d'une cuve est passé de 5 à 8 mn. Ces résultats permettent un gain d'exploitation notable ainsi qu'une amélioration de la qualité du travail réalisé. Suivant notre mode de réalisation, l'axe (3) en tournant, plus ou moins rapidement, entraîne le distributeur doseur formé d'une rondelle découpé pour former deux ergots, qui permet de doser l'agrégat de la cuve (4) en fonction du besoin de l'opérateur, tout en permettant au brasseur de déséquilibrer les zones de compactages, le brasseur devant avoir une forme suffisamment profilée, pour ne pas engendrer un couple trop important, mais pas trop, de façon à assurer la perturbation  And the second characteristic is the metering device, made up of a metal washer cut out to form two pins (2) always secured to the axis of rotation. Tests carried out using the new device show that the maximum flow rate has been multiplied by 1.4 and that the autonomy of a tank has increased from 5 to 8 minutes. These results allow a significant operating gain as well as an improvement in the quality of the work carried out. According to our embodiment, the axis (3) by turning, more or less quickly, drives the metering distributor formed by a cut-out washer to form two lugs, which makes it possible to dose the aggregate of the tank (4) in function the need of the operator, while allowing the brewer to unbalance the compaction zones, the brewer having to have a sufficiently profiled shape, so as not to generate too great a torque, but not too much, so as to ensure the disturbance
