Description

PROCEDURE AND DEVICES FOR THE EMISSION CONSTANT OF VOLATILE LIQUIDS n w s r! R t p c? or w OBJECT OF THE INVENTION The object of the invention is, as indicated in the statement, a "procedure and devices for emitting, in a constant manner, volatile liquids". The method proposed by the invention is based on the absorption of liquids and / or volatile solvents (with or without accompanying solutes) by absorbent solids of different materials and different nature or composition.

BACKGROUND OF THE INVENTION At present, to distribute volatile liquid products, such as insecticides, aromatic substances, disinfectants, phytosanitary, semochemical, etc., the use of propellants or devices is required, generally of manual, mechanical, thermoelectric or manual operation. others, which require permanent attention and, in many cases, it is practically impossible to use. On the other hand, these projection arrangements do not allow a constant emission of the volatile product concerned. In the specific case of having to distribute the product in large areas of crops and trees, applying the products involved requires a large number of special machinery and a large number of projectors which is practically impossible to install, particularly in the places where Hard access. The known diffusers, with scientific basis, - based on the mechanics or the physics of fluids, have not given satisfactory results in. equatorial or tropical environments- with extreme climatic conditions of high daytime temperatures, with a high degree of relative humidity and sudden drops in temperature during twilight and night hours with humidity close to 100%. On the other hand the use of additional motor elements, of a mechanical or thermoelectric nature that could solve (in fact it does), this problem, supposes an increase of the same and the impossibility to realize it in places of difficult access, without electricity or fuels for the engine system.

The invention presents a simple and effective solution for the problems indicated and for this purpose it proposes a procedure and special devices that are described below. The use of the diffusers currently available in the market for agroforestry research uses, in environments and continental temperate climates, presents several inconveniences of the practical order, more or less surmountable with small modifications, different manuals for each case. However, the use of known diffusers in humid, equatorial rainforest areas does not meet the minimum operational requirements. Bearing in mind that in the investigations carried out, more or less calibrated diffusers were used, the resolution of the impediments of the current-in operation that were presented, due to basic failures of the instruments, was the previous step for the execution of the work. In the first place, the causes of the failure of the known diffusers have been carefully examined, mainly due to the drastic environmental conditions of temperature and humidity prevailing, particularly in the Amazon rainforest. During the daytime hours with a constant temperature of 30 ° C and a relative humidity of never less than 85%, the diffusion of the volatile liquids was carried out at an extremely high rate (evaporated volume / unit of time). Contrary to twilight, when the relative humidity rose to 100% (condensation) and the temperature dropped below 18 ° C, the condensation water created a watertight chamber around the diffuser that completely inhibited the evaporation of the volatile liquid. spread. As the original causes of the failure of the known diffusers could not be obviated through modifications of the same, it had to resort to create other devices. This is how a diffuser was designed, could effectively meet the established needs. The results obtained, which obviate the slowdown of diffusion by the condensation of water when the relative humidity almost reaches 100% as well as the continuous and regular diffusion rates that could be varied from 0.5 to more than 2cc. newspapers allowed to create this system that is proposed in the present document. It is understood that the invention has a large number of health, cosmetic, agricultural, forestry, etc. applications. , etc .

DESCRIPTION OF THE INVENTION In the exposed procedure, the absorption of liquids and / or volatile solvents (with or without accompanying solutes) is verified by absorbent solids, which are released as gas by the physical principle of vapor tension difference and air entrainment. , without intervention of the own weight of the liquid or solvent and without using motor or thermoelectric devices or propellants by compressed fluids. By means of the procedure advocated by the invention, the constant diffusion of the substances of interest is achieved freely or controlled depending on the option desired. In order to carry out the aforementioned procedure, the following provisions have been foreseen: a) A tank that contains, in a liquid state, the product or composition to be spread. b) An absorbent-diffusing mass that is lodged properly conditioned and protected in the aforementioned deposit, in which it is submerged totally or partially in the liquid product that is to be diffused. c) A tubular body, with multiple strategically distributed perforations in which an absorbent mass is lodged. d) A perpendicular tube or sleeve incorporated or integral with the lid that closes the container, whose sleeve has adjusted tightly the tubular body containing the absorbent mass so that it is immersed in the liquid containing the reservoir. e) A cover that closes the tank, establishing with it a practically hermetic closure, whose lid keeps the tubular element in an erect position with perforations; at its upper end, the liquid product contained in the tank flows in a gaseous state. f) The tubular body with drafts that involves the absorbent mass, has its upper zone without absorbent material, forming in it a chamber in which the openings are not blocked so that they penetrate outside air that induces the gas, which flows to this camera, taking it to the exit step. g) A discoidal lid, with a central draft, which fits snugly over the upper end of the tubular body with holes, closing the free chamber formed therein. h) A canopy-like lid, which closes the free upper end of the device, which covers and protects the exit passage of the product in a gaseous state to prevent its sealing. A more complete idea of the object that constitutes the invention, is provided by the following description, when considered, together with the accompanying drawings, in which the schemata are represented in a somewhat schematic manner and exclusively as a non-imitative example. sets and the preferred details of the devices that make it possible to carry out the object that constitutes the invention. In the drawings: Figure 1 is a view in elevation, with a half section through a vertical plane, of the tubular element with drafts that in its interior houses the absorbent mass. Figure 2a, represents the breakdown of the set of elements that make up the general device with which the emission of liquid product of interest occurs. Figure 3a represents elevation with a half section by a vertical plane, the set of devices that once grouped form the diffuser that is represented fully armed and containing in its tank the liquid product to be dispensed. Commenting now on these drawings, the explanation is made that, by means of n ° -1-, the deposit containing the liquid product is indicated, the level of which is indicated by the. n ° -2-. In the practical embodiment of the invention, this reservoir forms a vessel that has means -3- to receive and tightly retain a discoidal lid -4-, with which it establishes a practically hermetic closure; this cover -4- has in its center a wide draft encircled by the neck -6- which extends on both sides, forming a tubular housing in which a tubular cylindrical element -7- which is practiced by the entire surface, 18-strategically distributed sprays. In the interior of the tubular element -7- an absorbent mass is lodged -9-; said tubular element -7- penetrates perpendicularly in the tank -1- until it rests on its bottom, maintaining itself securely in erect position and projecting superiorly from the cover -4- in a suitable sector that is devoid of absorbent mass -9-; this free sector forms a chamber -10- in which, by its drafts -8-, the ambient air penetrates displacing the gases detached from the absorbent mass, making them flow through the passage practiced in the center of a closing part -11- that fits, tightly, on the upper end of the tubular element -7-, this closing piece, finally, is covered with a cap supported by ribs -14- emerging from an annular sector of base -15- that fits on the cover -11- which closes above, the tube with holes -7-. Inside the tank -1- the product or preparation is placed in liquid state -2-, in which other components in a state of fine division or solid can be included, as indicated by No. -16-. It is understood that once the product or composition is prepared, in the liquid state to be dispensed, it is introduced into the tank -1- until reaching a conventional level -2- and optionally solid or dusty components -16- are incorporated. In the tank the tubular body -7- provided with the drafts -8- is inserted perpendicularly, which inside it houses an absorbent mass -9-, whose tubular element remains submerged, in erect position, in the-liquid so that, through its holes -8- impregnates the entire absorbent mass -9- flowing from it, in a gaseous state and penetrating into the upper chamber -10- and from this, being induced to the passage -12- by the air that it penetrates the chamber 10 formed at the upper end of the tubular element with perforations 7 to finally spread through the external environment. On the upper end of the tubular body -7- and its lid -11- is a covering piece formed by a substantially conical cap -13- supported by vertical ribs -14- starting from an annular base -15- adapted , tightly, on the cover -11- which closes the upper end of the central body -7-. Conveniently describing the nature of the invention, it is pointed out for the appropriate purposes that the invention is not strictly limited to the exact details of this exhibition since, when implemented, it is possible to introduce detailed modifications therein, provided that variations that are introduced does not alter the essentiality of the invention.
