Definitions

  • the present invention relates to spraying devices and relates to a rotary atomizer system.
  • the spraying of active material uses pressure atomization, that is to say by tearing a liquid stream through an orifice.
  • active material such as insecticides, fungicides, anti-weeds, etc.
  • pressure atomization that is to say by tearing a liquid stream through an orifice.
  • the spectrum of the diameter of the drops created by this system is very wide and is a function of all the parameters of the system, pressure, flow rate, diameter of the orifice, etc., which complicates its regulation.
  • an atomization turbine according to the invention is characterized in that it is in the form of a squirrel cage fan turbine, in that the blades are curved or straight, and in that inside the turbine are annularly distributed around the axis of the turbine and in a symmetrical manner at the base of the blades one or more fixed, solid, perforated injection pipes or soft.
  • the internal and / or external faces of the blades are provided with fine grooving and / or end in fine toothing.
  • the stationary injector pipe (s), the orifices of which are placed perpendicular to the blades of the turbine, are distributed either parallel or helically to the axis of the turbine.
  • the atomizing turbine is fixed at the end of the motor shaft and the injectors are integral with the body of said motor.
  • the atomization turbine is mounted on a bearing placed on an axis fixed to said machine or to the wing of the plane, either using an appropriate flange, or screwed directly onto the nozzle of the jet holder.
  • the atomizing turbine is associated with a means producing around it a current of air.
  • the atomizing turbine is included inside a casing, so as to allow the air charged with droplets produced by the turbine to be directed laterally.
  • the atomization turbine 1 is similar to a squirrel cage fan turbine and it has a fine toothing at the end of its blades 2.
  • Injector pipes 4, comprising orifices 5 which are advantageously placed in the direction opposite to the flow of the liquid to be sprayed, are distributed symmetrically inside the turbine, at the base of the blades and parallel to the axis of the turbine.
  • injectors 4 are fixed, they do not rotate. Their number depends on the desired flow range.
  • the atomization turbine 1 is driven by the air stream, in which it is placed.
  • the turbine In the case of a spraying machine producing an air current or in the case of aerial spraying, the turbine is mounted on two bearings 6, themselves placed on an axis fixed to the machine or to the wing of the aircraft. using a profile upright 7.
  • the speed of rotation is regulated by a system regulating the air flow entering the turbine. This air passes through the blades, drives the atomizer and increases the atomization of the product to be sprayed injected at the base of the blades by the injector pipes 4, which are fixed annularly around the fixed axis and / or to the upright connecting l machine axis.
  • the atomization turbine 1 is mounted directly on the axes of the hydraulic drive motor 8.
  • Injector pipes 4 having injection orifices 5 are distributed symmetrically with the interior of the turbine, at the base of the blades 2, having a fine toothing 3 at their end, and parallel to the axis of the turbine and are integral with the body of the engine 8.
  • the drops produced are of a very small diameter. This is sought to increase the effectiveness of the spraying but, to avoid their dispersion by the wind before they reach their goal, a current of air is produced which forces the drops produced by the atomizer 1 ′ towards their goal.
  • an axial fan 12 with two or more orientable blades 13 is placed between this fan 12 and the atomization turbine 1 ′, that is to say over the thickness of the drive motor 8, so as to increase the working width and the efficiency of penetration into the vegetation.
  • An aerodynamically shaped cap 15 serving as protection covers the whole, motor 8 - fan 12.
  • the blades 2 ′ of the turbine 1 ′ are of curved shape and provided on their face with a fine grooving 16 ending at the end of the blade in fine toothing 3.
  • the injection conduits 4 ′ are here provided with a distribution and transfer strip 17 optionally provided with a fine toothing 3.
  • Atomization turbines according to the invention are intended to be mounted on existing spraying apparatus, carried, towed by agricultural tractors or mounted on aircraft.
  • an existing pressurization system brings the product to be sprayed to each turbine, which has a calibrated orifice placed upstream of the injection system 16.
  • the flow rates of the product to be sprayed are varied, independently of the speed of rotation of the turbine.
  • the invention makes it possible to disperse extremely small volumes of liquid per unit area with increased treatment efficiency, while providing substantial savings on the cost of the products used and reducing pollution of the soil and the atmosphere.
  • the pollution of the soil is reduced, because the atomization turbine does not produce large diameter drops, which do not cling to the goal but fall to the ground and which represent a loss of large volume.
  • Air pollution is reduced thanks to the induced air current, which forces the fine drops towards their goal instead of leaving with the wind.
  • regulation of the spraying parameters is provided by a computer system, which regulates the pressure of the liquid upstream of the calibration orifice as a function of the speed of advance of the sprayer and of the desired flow rates.
  • the drop size spectrum which is the new independently adjustable parameter, is also electronically controlled and regulated.
  • a hydraulic pump with variable flow and electronic control is mounted on the sprayer or the tractor.
  • the flow rate of the hydraulic pump is automatically regulated according to the drop size requested.
  • the system automatically maintains the desired drop size by keeping the rotation speed of the atomization turbines constant, whatever the speed of the hydraulic pump drive, by regulating the flow rate of this pump.
  • an atomizing turbine 1 is advantageously included in a suitable casing 18, as shown in FIG. 9.
  • This casing 18 makes it possible to direct laterally (arrow x) air charged with droplets produced by the turbine.
  • a system for recycling the slurry entering 19 is provided at 20 and 20 ′, so as to recycle contamination of the internal faces of the casing 18, so that this contamination does not disturb the drop spectrum.
  • the invention applies to various fields, such as the protection of crops and forests, the application of fertilizers, the fight against invasion (grasshoppers, tsetse flies, mosquitoes, etc.) and all other fields where a liquid should be sprayed.
