Abstract
Description
La présente invention a pour objet une buse à déflecteur concave pour projection de liquide.The present invention relates to a concave deflector nozzle for spraying liquid.
Elle est destinée au lavage des filtres utilisés en particulier dans l'industrie de traitement des engrais phosphatés.It is intended for washing filters used in particular in the phosphate fertilizer processing industry.
Les dispositifs réalisés à ce jour sont fabriqués en métal coulé ou usiné. Le nettoyage des filtres utilisés dans ce type d'industrie nécessite de grande quantité d'eau, et du fait que les sources de phosphates sont le plus souvent situées dans des régions où elle est rare et chère, I'eau est généralement recyclée et se charge progressivement de particules abrasives qui provoquent une usure rapide des buses de projection qui doivent par conséquent être remplacées à des intervalles rappro chés, ce qui entraîne non seulement des frais importants pour l'approvisionnement des pièces de remplacement, mais également des arrêts de production fréquents.The devices produced to date are made of cast or machined metal. The cleaning of filters used in this type of industry requires a large amount of water, and since the sources of phosphates are most often located in regions where it is scarce and expensive, the water is generally recycled and gradual loading of abrasive particles which cause rapid wear of the spray nozzles which must therefore be replaced at short intervals, which not only entails significant costs for the supply of replacement parts, but also frequent production stoppages .
Le dispositif suivant la présente invention supprime ces inconvénients. En effet, il permet de réaliser des buses ayant une durée de vie incomparablement plus longue, et dont les parties soumises à forte usure peuvent être remplacées, d'où une diminution des pièces de remplacement à stocker.En outre le débit peut être ajusté en changeant seulement l'ajutage et non l'ensemble de buse.The device according to the present invention eliminates these drawbacks. Indeed, it makes it possible to produce nozzles having an incomparably longer lifespan, and whose parts subjected to high wear can be replaced, hence a reduction in the replacement parts to be stored. In addition, the flow rate can be adjusted by changing only the nozzle and not the nozzle assembly.
Il est constitué par la combinaison d'un corps métallique issu de fonderie ou usiné comportant un ajutage et un déflecteur tous deux équipés d'une pièce d'usure rapportée en céramique, fixée préférentiellement par collage.It is formed by the combination of a metal body from foundry or machined comprising a nozzle and a deflector both fitted with a wear part in ceramic, preferably fixed by gluing.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention:
La figure 1 est une coupe longitudinale du dispositif.In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention:
Figure 1 is a longitudinal section of the device.
La figure 2 est une coupe transversale suivant les flèches A-A de la figure 1.FIG. 2 is a cross section along the arrows A-A of FIG. 1.
La figure 3 représente le dispositif vu de dessus.Figure 3 shows the device seen from above.
La figure 4 montre une rampe équipée de plusieurs dispositifs raccordés à un distributeur.Figure 4 shows a ramp equipped with several devices connected to a distributor.
Le dispositif, figure'l à 3, est constitué d'un corps de buse 1, en acier coulé ou usiné, comportant un raccord fileté 2, un perçage 3 et un support de déflecteur 4. The device, FIG. 1 to 3, consists of a nozzle body 1, made of cast or machined steel, comprising a threaded connection 2, a bore 3 and a deflector support 4.
Le perçage 3 est équipé d'un ajutage cylindrique 5 en céramique pouvant être remplacé. De même, le support de déflecteur 4 est pouvu d ' un déflecteur remplaçable 6, également en céramique, avec une surface plane 7 de préférence collée sur le corps du dispositif, et une surface galbée 8, concave, destinée à briser le jet arrivant par l'ajutage 5. La fixation des pièces d'usure en céramique 5, 6 peut être réalisée par tout moyen permettant le démontage en particulier, l'ajutage 5 peut être entré à force dans le perçage 3.The hole 3 is equipped with a cylindrical ceramic nozzle 5 which can be replaced. Similarly, the deflector support 4 is capable of a replaceable deflector 6, also made of ceramic, with a flat surface 7 preferably glued to the body of the device, and a curved surface 8, concave, intended to break the jet arriving by the nozzle 5. The fixing of the ceramic wearing parts 5, 6 can be carried out by any means allowing disassembly in particular, the nozzle 5 can be forced into the hole 3.
La durée de résistance des pièces en céramique 3 et 6 à l'usure provoquée par les particules abrasives contenues dans 1' eau de lavage est beaucoup plus grande que pour les surfaces métalliques, et ces pièces sont seules à être remplacées lorsque cela est nécessaire, le corps 1 de la buse étant réutilisé.The duration of resistance of the ceramic parts 3 and 6 to the wear caused by the abrasive particles contained in the washing water is much greater than for metallic surfaces, and these parts are the only ones to be replaced when necessary, the body 1 of the nozzle being reused.
Sur la figure 4, on peut voir un certain nombre de buses montées sur un support 9 de manière à former une rampe, et raccordées à un distributeur d'eau sous pression 10 par des raccords flexibles 11 évitant la transmission des vibrations. In Figure 4, we can see a number of nozzles mounted on a support 9 so as to form a ramp, and connected to a pressurized water distributor 10 by flexible connectors 11 preventing the transmission of vibrations.
Grace à sa grande résistance à l'usure, à la diminution des arrêts de production qu'il permet, le dispositif qui vient d'être décrit se prête particulièrement bien à la réalisation de rampes de nettoyage de filtres dans tous les cas où les produits traités contiennent des éléments abrasifs et où 1' eau de lavage doit être recyclée. Thanks to its high resistance to wear, to the reduction in production stoppages that it allows, the device which has just been described lends itself particularly well to the production of filter cleaning ramps in all cases where the products treated contain abrasive elements and where wash water must be recycled.
Le positionnement des divers éléments constitutifs donnent à ce dispositif un maximum d'effets utiles qui n'avaient pas été obtenus à ce jour par des dispositifs similaires. The positioning of the various constituent elements gives this device a maximum of useful effects which had not been obtained to date by similar devices.
