Furthermore, the system allows the drying of the packages. c/ Principal uses: The invention may be used for the spreading of phytopharmaceutical products from agricultural sprayers or for the dosing of industrial chemical products by means of adapted machines.

Description

DESCRIPTION a/Titre de l'invention: Système clos de transfert de produits chimiques et des eaux de rinçage. DESCRIPTION a / Title of the invention: Closed system for transferring chemicals and rinsing water.

b/Au moins 1 secteur de la technique sur laquelle porte l'invention:
La présente invention concerne le transfert des produits phytopharmaceutiques nécessaires a l'agriculture, qu'ils soient sous forme liquide, poudre mouillable ou granulés dispersibles, vers la cuve, sans contact physique ou risque d'inhalation. La présente invention concerne également tout transfert de produits chimiques nécessaires à l'industrie.b / At least 1 sector of the technique to which the invention relates:
The present invention relates to the transfer of plant protection products necessary for agriculture, whether in liquid form, wettable powder or dispersible granules, to the tank, without physical contact or risk of inhalation. The present invention also relates to any transfer of chemicals necessary for industry.

c/l'état de la technique dans le secteur considéré:
Dans des dispositifs connus de ce genre, il y a un risque potentiel de pollution par retour de la bouillie de pulverisation dans le milieu (rivière, mare, réseau d'eau), abandon d'emballages non rincés, renversement accidentel des emballages, contact physique et inhalation par le manipulateur, d/Au moins un résultat que l'invention vise à obtenir:
Le dispositif, suivant l'invention, permet d'éviter les inconvénients ci-dessus. dans celui-ci en effet, les produites chimiques sont manipulés dans de bonnes conditions de sécurité car l'opercule d'étanchéité des emballages n'est découpé qu'apurés vissage étanche de l'emballage sur le système.c / state of the art in the sector considered:
In known devices of this kind, there is a potential risk of pollution by return of the spray mixture to the environment (river, pond, water network), abandonment of non-rinsed packaging, accidental spillage of the packaging, contact physical and inhalation by the manipulator, d / At least one result which the invention aims to obtain:
The device according to the invention avoids the above drawbacks. in this one, in fact, the chemical products are handled under good safety conditions because the seal for sealing the packages is only cut off after the packaging has been tightly sealed onto the system.

Le rinçage de l'emballage et éventuellement le séchage est effectué avant désolidarisation de l'emballage et de l'invention; les eaux de rinçage quant a elles étant transférées dans le système de pulvérisation toujours en systeme cl os e/Les moyens mis en oeuvre pour parvenir à ce résultat:
Le dispositif objet de l'invention, comporte un système qui se visse de façon étanche à la place du bouchon de l'emballage sans avoir au préalable retiré ou perforé l'opercule d'étanchéité de l'emballage. Un système de couteau à rotation partielle vient découper l'opercule de façon à ne laisser qu'une petite partie non sectionnée, un mouvement latéral du couteau permet de maintenir l'opercule en position ouverte, ce qui autorise le passage quasi total du produit.The packaging is rinsed and optionally dried before the packaging and the invention are separated; the rinsing water being transferred to the spraying system always in the closed system / The means used to achieve this result:
The device which is the subject of the invention comprises a system which is screwed tightly in place of the packaging cap without having previously removed or punctured the sealing cap of the packaging. A knife system with partial rotation cuts the cover so as to leave only a small portion which is not cut, a lateral movement of the knife keeps the cover in the open position, which allows the almost total passage of the product.

Ce système est relié d'une façon étanche à la trémie hermétique graduée. Cette trémie est connectée à sa base à un système hydro-injecteur. This system is tightly connected to the graduated hermetic hopper. This hopper is connected at its base to a hydro-injector system.

Un système de vanne et clapet permet alors de transférer tout ou partie du produit. Lorsque la totalité du produit à été transféré dans la cuve, un injecteur placé sur le support du couteau rotatif permet de propulser à volonté dans l'emballage et plus particulièrement sur les parios un liquide de rinçage ou de l'eau claire.ce liquide de rinçage est ensuite repris par l'hydro-injecteur et transféré vers la cuve.(l'invention prévoit une pos sibil ité de séchage interne de l'emballage avant démon788jstème) .Le système de flotteur à niveau de la trémie hermétique graduée évite l'introduction d'air dans le système en fermant l'orifice au niveau bas, et par conséquence élimine tout ou partie le phénomène de mousse souvent générateur de pollution.A valve and flap system then makes it possible to transfer all or part of the product. When all the product has been transferred to the tank, an injector placed on the support of the rotary knife allows to propel at will in the packaging and more particularly on the parios a rinsing liquid or clear water. rinsing is then taken up by the hydro-injector and transferred to the tank. (the invention provides for a possibility of internal drying of the packaging before dismantling). The float system at the level of the hermetic graduated hopper avoids the introduction of air into the system by closing the orifice at a low level, and consequently eliminates all or part of the foam phenomenon often generating pollution.

L'installation de deux systèmes de fixation des emballages sur la trémie hermétique graduée de réception et de pré-mélange permet de mélanger deux produits compatibles et de façon précise. Le système, rapide de fixation sur la trémie hermétique graduée, permet de changer facilement le format des emballages. et assure la rotation du systeme de faxation étanche pour permettre l'écoulement du produit par gravité de l'emballage vers la trémie graduée. The installation of two packaging fastening systems on the hermetic graduated receiving and pre-mixing hopper makes it possible to mix two compatible products precisely. The system, quick to attach to the graduated hermetic hopper, allows the packaging format to be changed easily. and ensures the rotation of the sealed faxing system to allow the product to flow by gravity from the packaging to the graduated hopper.

La mise à pression atmosphérique de la trémie graduée se fait par un tuyau souple qui est relié au sommet de la cuve principale ce qui évite tous risque de polution accidentele. The graduated hopper is brought to atmospheric pressure by a flexible pipe which is connected to the top of the main tank which avoids any risk of accidental pollution.

Un clapet antiretour evite le retour de la cuve vers la trémie
Un deuxieme clapet antiretour place sur l'arrivée d'eau empèche le retour du produit vers le milieu.A non-return valve prevents the return of the tank towards the hopper
A second non-return valve placed on the water inlet prevents the product from returning to the middle.

Apres rinçage il est possible d'injecteur par le circuit de rinçage un fluide de séchage , les vapeurs étant dirigée par la mise a pression atmos phérique vers le haut de la cuve, ce qui diminue les risque de polution. After rinsing it is possible to inject a drying fluid through the rinsing circuit, the vapors being directed by the atmospheric pressure upward of the tank, which reduces the risk of pollution.

L'angle prédéfini d'inclinaison de l'injecteur placé sur le support du couteau permet le rinçage des parois de l'emballage, la rotation du couteau permet de diriger le jet. The predefined angle of inclination of the injector placed on the knife holder allows the walls of the packaging to be rinsed, the rotation of the knife allows the jet to be directed.

La liaison du systeme de fixation sur la trémie se fait par un cliptage rapide et étanche autorisant la rotation et la mise en oeuvre d'emballage ayant des diamètres différents. The connection of the fixing system on the hopper is done by a fast and watertight clipping allowing the rotation and the implementation of packaging having different diameters.
