- 1 La présente invention concerne un filtre à rinçage continu, principalement destiné aux machines de protection des plantes dans l'agriculture et dont l'entrée est reliée à une conduite d'alimentation, la sortie à 5 une conduite avec buse et la chambre intérieure à un réservoir On connaît un filtre à effet de rinçage, principalement destiné aux machines de protection des plantes dans l'agriculture, d'après la revue spécialisée 10 "AGRARTECHNIK" (RFA, mai 1986), dont le principe de construction réside en ce que son entrée est reliéeàlaconduite d'alimentation, sa sortie à la conduite pourvue d'une buse et sa chambre intérieure à un réservoir par l'intermédiaire The present invention relates to a continuous rinsing filter, mainly intended for plant protection machines in agriculture and whose inlet is connected to a supply pipe, the outlet to a pipe with nozzle and the inner chamber. to a tank A rinsing effect filter is known, mainly intended for plant protection machines in agriculture, according to the specialist journal "AGRARTECHNIK" (FRG, May 1986), the construction principle of which lies in this that its inlet is connected to the supply line, its outlet to the line provided with a nozzle and its interior chamber to a tank via
d'une soupape d'arrêt.a shut-off valve.
L'inconvénient de cette solution connue réside en ce que le rinçage s'effectue avec des interruptions sous l'effet d'actions extérieures, est inefficace en raison du caractère subjectif de la modification decapacité du filtre et rend nécessaire une surveillance particulière, 20 ce qui fait que le filtre n'est-guère rentable dans ces conditions. L'invention se fixe pour objet de supprimer les inconvénients ci-avant mentionnés, c'est-à-diredecréer un The disadvantage of this known solution is that the rinsing takes place with interruptions under the effect of external actions, is ineffective due to the subjective nature of the change in filter capacity and makes special monitoring necessary. which means that the filter is hardly profitable under these conditions. The object of the invention is to eliminate the aforementioned drawbacks, that is to say to create a
filtre à rinçage continu, autrement dit pourvu d'une 25 capacité de nettoyage automatique. continuous rinsing filter, in other words provided with an automatic cleaning capacity.
Le but de cette invention consiste dans la réalisation d'un filtre, dont les impuretés sont expulsées d'elles-mêmes, sans que ces impuretés se fixentenunendroit The object of this invention consists in the production of a filter, from which the impurities are expelled by themselves, without these impurities being fixed in a place.
indésiré ou sans qu'on ait à interrompre, à l'occasion, 30 le fonctionnement du filtre. unwanted or without having to interrupt the operation of the filter on occasion.
Le problème posé a été résolu selon l'invention, sur le filtre du type déjà mentionné, en ce que sa chambre intérieure et le réservoir sont reliés par une The problem posed has been solved according to the invention, on the filter of the type already mentioned, in that its inner chamber and the reservoir are connected by a
soupape de régulation de pression. - pressure regulating valve. -
-2 Pour l'amélioration de l'efficacité, le mode de réalisation selon lequel la chambre intérieure du filtre est reliée au réservoir par l'intermédiaire d'une soupape de régulation de pression qui est disposée du côté opposé à l'entrée est avantageuse. Il convient ici d'exposer l'invention dans ses détails d'après un-dessin correspondant à un exemple d'exécution adéquat. Le dessin représente sur la figure 1, -2 For the improvement of efficiency, the embodiment in which the inner chamber of the filter is connected to the tank through a pressure regulating valve which is disposed on the side opposite to the inlet is advantageous. . It is appropriate here to set out the invention in its details according to a drawing corresponding to a suitable example of execution. The drawing shows in figure 1,
le schéma d'un filtre selon l'invention. the diagram of a filter according to the invention.
L'entrée 1 du filtre selon l'invention est reliée à la conduite d'alimentation 2 et la sortie 3 est reliée The inlet 1 of the filter according to the invention is connected to the supply line 2 and the outlet 3 is connected
à la conduite avec buse 4.to pipe with nozzle 4.
La chambre intérieure 5 du filtre selon l'invention The inner chamber 5 of the filter according to the invention
est reliée par une conduite 6 à un récipient (réservoir) 15 qui n'a pas été représenté ici. is connected by a pipe 6 to a container (reservoir) 15 which has not been shown here.
Une soupape de régulation de pression 7 est disposée sur la conduite 6 entre la chambre intérieure 5 A pressure regulating valve 7 is arranged on the pipe 6 between the inner chamber 5
et le réservoir.and the reservoir.
Le fonctionnement du filtre selon l'invention est 20 exposé en détail ciaprès. The operation of the filter according to the invention is explained in detail below.
Le liquide non filtré, qui est refoulé par la The unfiltered liquid, which is discharged through the
pompe dans la conduite 2 s'écoule dans la chambre intérieure 6 du filtre selon l'invention. pump in line 2 flows into inner chamber 6 of the filter according to the invention.
A partir de là une partie du liquide s'engage dans 25 la conduite avec buse 4 après avoir traversé une cartouche filtrante 9, tandis que l'autre partie qui correspond au surplus de liquide refoulé par la pompe, s'écoule par une soupape de régulation de pression 7, qui est disposée From there a part of the liquid enters the pipe with nozzle 4 after passing through a filter cartridge 9, while the other part, which corresponds to the surplus liquid delivered by the pump, flows through a relief valve. pressure regulation 7, which is arranged
rationnellement sur le côté 8 opposé à l'entrée 1 et une 30 conduite 6 la ramène dans le réservoir 1. rationally on the side 8 opposite to the inlet 1 and a pipe 6 brings it back to the tank 1.
En raison du retour du liquide, cette conduite entraîne de manière continue les impuretés séparées par filtrage du liquide, autrement dit il se produit un effet Due to the return of the liquid, this line continuously entrains the impurities separated by filtering from the liquid, in other words there is an effect
de rinçage continu.continuous rinsing.
Les avantages du filtre selon l'invention résident en ce qu'il garantit un auto-nettoyage continu sans intervention basée sur une appréciation subjective ni interruption de service; en outre, la soupape de régulation de 5 pression qui est, du reste, nécessaire, de toute façon The advantages of the filter according to the invention reside in that it guarantees continuous self-cleaning without intervention based on a subjective assessment or interruption of service; furthermore, the pressure regulating valve which is, moreover, necessary anyway
pour le système d'écoulement du liquide, est pourvue avec le filtre selon l'invention d'une double fonction, ce qui a pour effet d'augmenter sa rentabilité et enfin il n'est pas besoin d'équipements supplémentaires, ce qui garantitle 10 caractère économique du filtre. for the liquid flow system, is provided with the filter according to the invention with a dual function, which has the effect of increasing its profitability and finally there is no need for additional equipment, which guarantees the 10 economics of the filter.
