Abstract

The invention relates to a device making it possible to dispense pulverulent products into existing installations having standardised characteristics with an increased flowrate. It is constituted on the basis of powder-transportation equipment, of a collector tubing 2 capable of being connected either to the existing installations with standardised tubing, via a reduction connection 7 permitting a smaller flowrate, or to an overhead dispensing boom 5 of larger diameter for delivery under gravity with an increased flowrate. The device may be applied particularly to the dispensing of products intended for animal feeding.

Description

La présente invention concerne un dispositif de vidange pneumatique a compresseur ou surpresseur et à 2 vitesses de débit optimisèes,utllisable sur camion, remorque, semi remorque ou conteneur amovible Lie
Le stockage d'aliments du bétail s'effectue généralement dans des boisseaux remplis pneumatiquement par des camions .Les tuyaux de remplissage es installations fixes standardisés au diamètre nominal maximum de 100 mm et le débit du compresseur n'autorisent qu'un débit moyen de 30 tonnes heures.The present invention relates to a pneumatic emptying device with compressor or booster and with 2 optimized flow speeds, usable on truck, trailer, semi-trailer or removable container Lie
Livestock feed storage is generally done in bushels pneumatically filled by trucks. The filling pipes and standardized fixed installations with a maximum nominal diameter of 100 mm and the compressor flow allow only an average flow of 30 tonnes hours.

La figure 1 reorésente ce type de distribution,
Les produits sous pression couler' t par les évente coniques (1) dans une tubulure collectrlce (2) au diametre < = 100 mm ou ils sont propulsés par de l'air comprimé issu du compresseur (3) .Le vé i cul e est relié au bo i esea par un tuyau souple (4) de diamètre similaire.Figure 1 shows this type of distribution,
The pressurized products flow through the conical vents (1) into a manifold (2) with a diameter <= 100 mm or they are propelled by compressed air from the compressor (3). connected to the bo i esea by a flexible hose (4) of similar diameter.

Le dispositif proposé consiste à équiper les véhlcules d'un boyau collecteur (2) de diamétre nominal DN: 125 mm < =
DN < = 150 mm et d'un compresseur ou surpresseur de débit approprie
La vidange traditionnelle au débit de 30 tonnes par heure environ s'effectue par l'adaptation au boyau collecteur (2) d'un collier réducteur amovible (7) réduisant le diamètre de DN à 100 mm permettant l'utilisation du tuyau souple (4) de jonction au boisseau.The proposed device consists in equipping the vehicles with a collecting hose (2) of nominal diameter DN: 125 mm <=
DN <= 150 mm and an appropriate flow compressor or booster
Traditional emptying at a flow rate of approximately 30 tonnes per hour is carried out by adapting the removable hose (2) to a removable reducing collar (7) reducing the diameter of DN to 100 mm allowing the use of the flexible hose (4 ) to the bushel connection.

La vidange a débit rapide s'effectue par l'utilisation d'une perche de distribution multidirectionnelle (5) de diamètre DN reliée au boyau collecteur par une tubulure amovible souple ou rigide et permettant le remplissage du boisseau par le trou d'homme (6) situé a son extrémité supérieure.L'adaptation des débits de produit se faisant de manière proportionnelle à l'ouverture de la vanne située à la base des évents coniques,l'adaptation des débits d'air par modificatior, du régime compresseur
La figure 2 représente une coupe avant de principe des vannes des évents coniques de vidange de cuve
Un vérin double effet (10) est salidaire de la cuve de transport (1) par une traverse (13) et de gui des de déplacement (8) .The rapid flow emptying is carried out by the use of a multidirectional distribution pole (5) of diameter DN connected to the collecting hose by a flexible or rigid removable tubing and allowing the filling of the plug by the manhole (6 ) located at its upper end. The adaptation of the product flow rates is proportional to the opening of the valve located at the base of the conical vents, the adaptation of the air flow rates by modification, of the compressor speed
Figure 2 shows a front section in principle of the valves of the conical tank drain vents
A double-acting cylinder (10) is salidary to the transport tank (1) by a crosspiece (13) and mistletoe of the displacement (8).

Une vanne en cloche (9) qui obture le cone de descente
de la cuve de transport est sol idaire de 1 "axe d vérin double effet (10) .La descente des produits dans le tuyau collecteur (2) se réalise par injection d'air comprimé à la base du vérin par le tube (11) .L'ouverture différentielle selon le débit souhaité est fonction de la pression d'air appliquée dane le vérin et nécéssaire pour comprimer 2 ressorts concentriques (12) de longueur différente et/ou de coefficient d'élasticité différent.A bell valve (9) which closes the lowering cone
of the transport tank is ideal soil of 1 "double-acting cylinder axis (10). The products are lowered into the collecting pipe (2) by injecting compressed air at the base of the cylinder by the tube (11) The differential opening according to the desired flow rate is a function of the air pressure applied in the cylinder and necessary to compress 2 concentric springs (12) of different length and / or of different elasticity coefficient.

La régulation de débit d'air nécéssaire à la propulsion des produits soit par modification du régime du moteur entrainant le compresseur, soit par l'utilisation d'une boite de vitesse à 2 rapports placée avant le compresseur,soit par l'utilisation d'une prise de force dont les deux vitesses de rotation seront données par l'étage relais des bo@ies de vitesse des poids lourds.  The regulation of air flow necessary for the propulsion of the products either by modification of the engine speed driving the compressor, either by the use of a gearbox with 2 reports placed before the compressor, or by the use of a power take-off, the two rotational speeds of which will be given by the relay stage of the heavy goods vehicle speed booths.
