Antecedentes de la invenciónBackground of the invention

Hasta el momento los cañones y nebulizadores existentes en el mercado independientemente de la forma que adopten constan de una serie de boquillas nebulizadoras, que directamente éstas son las encargadas de atomizar el líquido. Los nebulizadores dependiendo de la forma de las bocas y sus características constructivas podrán ser de cobertura total o aplicación localizada.So far the cannons and nebulizers existing in the market regardless of the form they adopt they consist of a series of nebulizer nozzles, which directly These are responsible for atomizing the liquid. Nebulizers depending on the shape of the mouths and their characteristics constructive may be full coverage or application located.

Los nebulizadores hidroneumáticos necesitan de bombas de alta presión para producir la pulverización del líquido y los neumáticos utilizan la misma corriente del aire a gran velocidad (+ 100 m/sg) para producir esta pulverización.Hydropneumatic nebulizers need high pressure pumps to produce liquid spray and the tires use the same large air flow speed (+ 100 m / sg) to produce this spray.

Ahora, se pretende conseguir un cabezal nebulizador donde no sea preciso el empleo de boquillas nebulizadoras y por lo tanto de bombas de alta presión, empleando para ello un rotor que accionado por una corriente de aire, y ante el suministro del líquido, produzca la atomización del mismo.Now, it is intended to get a head nebulizer where the use of nozzles is not necessary nebulizers and therefore high pressure pumps, using for this a rotor that driven by an air current, and before the supply of the liquid, produces the atomization of the same.

Esta corriente de aire empleada será de velocidad media (60/70 m/sg) con lo que se eliminan también los problemas que produce la pulverización neumática al impactar contra la vegetación a gran velocidad.This air stream used will be of speed average (60/70 m / sg) which also eliminates the problems that produces pneumatic spraying when hitting vegetation at high speed.

Son conocidos los cabezales descritos en la patente EP442862, donde se muestra un cabezal adaptable a un spray de forma que consigue una más uniforme distribución del spray. De cualquier modo no se consigue una atomización o nebulización del agua.The heads described in the EP442862 patent, showing a spray adaptive head so that it achieves a more uniform distribution of the spray. From In any case, no atomization or nebulization of the Water.

En la patente US 4037789 se describe un dispensador de partículas de aerosol y la turbina necesaria para el mismo de utilización en la dispersión de herbicidas, funguicidas e insecticidas, empleando una corriente de aire a alta velocidad.In US Patent 4037789 a aerosol particle dispenser and turbine needed for the same for use in the dispersion of herbicides, fungicides and insecticides, using a high velocity air stream.

En la patente GB 2057299 se describe un aparato pulverizador que consta de un atomizador rotativo y un ventilador axial, acoplado al atomizador rotativo, conformando una unidad estructural.

The air jet passes through the fan and subsequently by the rotary atomizer, which consists of a spring valve actuated by the pressure of the chemical a dispense, the liquid coming out later through a grid that atomizes the liquid, so the liquid is dispersed by the effect of the fan, impacting the vegetation at a high speed.

Descripción de la invenciónDescription of the invention

El presente de la presente invención de cabezal centrífugo de accionamiento neumático para máquinas nebulizadoras consiste en un cabezal que directamente procede a la atomización o nebulización de todo el fluido suministrado, contando en su interior con un conjunto de rotor sobre el que hay dispuestos una serie de álabes o aletas.The present of the present invention of head pneumatically operated centrifuge for fogging machines It consists of a head that directly proceeds to atomization or nebulization of all the fluid supplied, counting in its interior with a rotor assembly on which a series of blades or fins.

Dicho rotor es accionado en su giro por una corriente de aire al quedar el rotor dispuesto de forma centrada sobre dicha corriente de aire.Said rotor is driven in its turn by a air flow when the rotor is arranged centrally over said air stream.

Sobre el extremo superior del rotor se encuentra unido un doble juego de discos enfrentados que cuentan con salientes dispuestos de forma concéntrica, de forma que durante el giro del mismo y al salir el agua, las gotas se estallan contra los salientes concéntricos de los discos por lo que se produce la atomización del agua y su distribución uniforme, pulverizando las gotas de agua a micras de diámetro.On the upper end of the rotor is joined a double set of facing discs that feature projections arranged concentrically, so that during the turn of it and when the water comes out, the drops explode against the concentric projections of the disks so the water atomization and its uniform distribution, spraying the water drops to microns in diameter.

El flujo de aire del cabezal centrífugo dispersa las gotas de agua lejos del operador, asegurando su completa dispersión. El conjunto permite el control de la atomización del agua o fluido a dispersar, consiguiendo de esta forma un correcto aprovechamiento de los productos químicos a dispersar, asegurando la máxima cantidad depositada.The air flow of the dispersed centrifugal head water droplets away from the operator, ensuring its complete dispersion. The set allows the atomization control of the water or fluid to disperse, thus obtaining a correct use of chemical products to disperse, ensuring  Maximum amount deposited.

El control del tamaño de las gotas de agua está basado en la velocidad de giro del rotor y de los discos atomizadores, y por lo tanto depende de la velocidad del flujo de aire impulsado sobre el cabezal.Water droplet size control is based on the rotational speed of the rotor and discs atomizers, and therefore depends on the flow rate of air driven over the head.

Los discos encargados de la pulverización del agua mediante la ruptura o estallido de las gotas de agua contra los salientes concéntricos con los que cuentan, están separados un disco del otro una distancia tal que aseguran el choque de las gotas contra uno u otro disco e incluso los dos.The disks in charge of spraying the water by breaking or bursting water droplets against the concentric projections they have, are separated a the other's disk a distance such that they ensure the shock of the drops against one or another disk and even both.

Los cabezales centrífugos conectados a una misma dorsal de distribución de aire pueden ser varios, de forma que la presión sobre dicha dorsal de aire en caso de tener varios cabezales conectados, deberá ser mayor.Centrifugal heads connected to the same Dorsal air distribution can be several, so that the pressure on said air dorsal in case of having several connected heads must be larger.

A la vista de las mencionadas figuras se describe a continuación un modo de realización preferente de la invención así como la explicación de los dibujos.In view of the aforementioned figures described then a preferred embodiment of the invention as well as the explanation of the drawings.

En la figura 1 observamos, cómo el cabezal cuenta con una carcasa (2) estrechada en su salida, con objeto de producir un aumento de la velocidad de giro del rotor. Por el extremo opuesto al de salida de los líquidos nebulizados, se conecta un conducto de aire (3), sujeto a la carcasa por medio de una abrazadera (4).In Figure 1 we see how the head counts with a housing (2) narrowed at its outlet, in order to produce an increase in the speed of rotation of the rotor. By the end opposite to the outlet of the nebulized liquids, a air duct (3), attached to the housing by means of a clamp (4).

En el interior de la carcasa (3) se encuentra dispuesto de forma centrada un rotor (1) en cuya superficie exterior se distribuyen regularmente una serie de álabes o aletas (6).Inside the housing (3) is centrally arranged a rotor (1) on whose surface outside a series of blades or fins are regularly distributed (6).

A través de la carcasa exterior se hace pasar un conducto (5), por cuyo interior circula el líquido a dispersar accionado por efecto de una bomba a baja presión. Dicho conducto conecta con el conjunto del rotor, discurriendo por su interior y saliendo al exterior a través del disco atomizador (7), encontrándose dispuesto de forma enfrentada otro disco atomizador de giro solidario con el anterior (8). Ambos discos cuentan con una serie de salientes dispuestos concéntricamente.Through the outer shell is passed a duct (5), through which the liquid to be dispersed circulates driven by the effect of a low pressure pump. Said conduit connects with the rotor assembly, running inside and going outside through the atomizing disc (7), being arranged facing another atomizer disk in solidarity with the previous one (8). Both discs have a series of protrusions arranged concentrically.

En la figura 2, observamos la forma que presenta uno de los discos atomizadores (7) u (8), donde cada uno de ellos cuenta con una serie de salientes dispuestos concéntricamente, de sección preferiblemente triangular. La distancia de los discos atomizadores (7) y (8) es tal que asegura el estallido de todas las gotas, ya que éstas bien golpean contra uno de los discos o ambos, posteriormente y tras la salida del agua nebulizada, es canalizada hacia el exterior a través de la carcasa por accionamiento del flujo del aire, y la ligera deflacción que presenta dicha carcasa (2) en su extremo de salida.In Figure 2, we observe the form it presents one of the atomizing discs (7) or (8), where each of them it has a series of concentrically arranged projections, of preferably triangular section. The distance of the disks atomizers (7) and (8) is such that it ensures the outbreak of all drops, since they hit one of the discs or both, subsequently and after the outflow of water mist, it is channeled outwards through the housing by actuating the air flow, and the slight deflation presented by said housing (2) at its exit end.

El tamaño de las gotas de agua, puede ser regulado dependiendo de la velocidad de giro y de la forma y medidas de los discos atomizadores, la cual a su vez depende de la velocidad del fluido o del aire.The size of the water drops, can be regulated depending on the speed of rotation and the shape and dimensions of the atomizing discs, which in turn depends on the speed of fluid or air.
