Description

Aerosol generator of multi-directional rotation disk type}

The present invention relates to a centrifugal rotating plate spraying device, and more specifically, to mechanically spray a small amount of chemical liquid in the form of ultra-fine particles, and at the same time to easily adjust the size or spraying amount of the particles, and in particular, it can be miniaturized and low speed It relates to a spray device of the centrifugal rotating plate to maximize the spray efficiency even with the driving force of.

In general, a separate gas is used as a propellant to make the liquid into aerosol particles having a size of spray particles of 25 μm or less.

In the past, Freon gas was almost used as a propellant, but as Freon was identified as a cause of destruction of the ozone layer, it is now used as an alternative material such as liquefied petroleum gas.

The materials used as propellants are usually filled in the form of flammable liquefied gas, which may cause a fire, and there is a closed stage where most of them disappear into the air when gas is sprayed.

And when the sprayed liquid is an insecticide, the insecticide is mainly in contact with insects or the insecticide must be fed by the insecticide, but the sprayed liquid is almost gasified and disappears, the current situation is insufficient.

On the other hand, in general, the spraying method of spraying pesticides using a nebulizer is impossible to spray a small amount of high active drug in a large area, so that a large amount of water is diluted and sprayed.

In this case, an emulsifier is usually used for dilution with water, and an adjuvant such as a dispersant, a fixing agent, and a moisturizer is used to compensate for the surface tension and volatility of the water.

However, the use of such various emulsifiers or auxiliaries not only increases the manufacturing cost of the sprayed chemical solution, but also makes it difficult to accurately match the dilution amount with water, so that it is difficult to have an appropriate mixing ratio.

In addition, the sprayed particles of the chemical liquid used as an insecticide are so large that they tend to settle down immediately after being sprayed, which causes a lot of loss, and contaminates the floor of the space, especially in a closed greenhouse or space where cleanliness should be maintained. There is a hassle to do.

In particular, the spraying method as before, there is a problem that the insecticidal efficiency is lowered due to a weak effect on the pest or crop immediately after spraying.

Meanwhile, in order to solve such a problem, a method of spraying a pre-prepared drug in the form of ultra fine particles has recently been proposed.

That is, in the conventional spraying method, water is diluted in the chemical solution. As a result, when the spray particles are made smaller, the water evaporates immediately, so that the absorption capacity of the pests or crops is not good. Even if the size of 50㎛ or less has the advantage that the control efficiency is further improved.

Such ultra-fine particle spreading method generally uses a device such as a cone nozzle or a nozzle using a compressed air and a whirlwind nozzle.

However, in this spraying method, not only the spray particle size of the chemical liquid is not constant, but also the end of the spray amount becomes uneven.

On the contrary, in recent years, a centrifugal rotating plate type that can uniformly form spray particles has been proposed.

However, conventional centrifugal spinnerets and similar devices have limitations on the size of the particles they can make.

That is, since the size of the particles is limited by the rotational speed of the rotating plate, in order to obtain spray particles having a diameter of 25 μm, the rotating disc needs to be rotated at a high speed of 20,000 rpm or more.

In addition, the spray particles generated by using a conventional centrifugal rotating plate atomizer are too large to drop on the floor immediately after spraying, making it difficult to use in clean environments such as homes. The fixed cylinder formed is installed so that the particles protruding from the disc become smaller due to the projections, but in reality, the particles are sprayed as the particles become smaller, and most of them are liquefied and flow down to the projections. The spray efficiency is low and spray particles are also nonuniform, such as the need for a separate liquid recovery container.

In particular, the conventional centrifugal rotary nebulizer has a problem that it is impossible to control the spray direction because the spray particles are dispersed in all directions (360 °) by the centrifugal force.

Therefore, the present invention has been invented to solve the above-mentioned problems of the prior art, and an object of the present invention is to electrically rotate a plurality of rotating plates facing each other separately from the liquid container so that the chemical liquid is rotated between the rotating plates at high speed. As it passes through, the chemical liquid is sprayed uniformly in the form of ultra-fine particles to maximize the chemical liquid spraying and control effects.

It is another object of the present invention to be able to freely control the spray amount to spray to the extent necessary for a variety of liquids.

In addition, the rotors 31b and 32b of the first motor 31 and the second motor 32 are rotated by a predetermined gap so as not to interfere at both ends of the tubular body 21 of the fixed frame 20. Make it possible.

The first rotating shaft member 40 is configured in the shape of a shaft, one end of which is fixed to the rotor 31b of the first motor 31, and the other part of the tubular body 21 of the fixed frame 20 is fixed. While penetrating horizontally to penetrate through the outer case 10 of the second motor 32 side.

At this time, the first rotation shaft member 40 inserted into the tubular body 21 is rotatably supported by the bearing 23 with the rotor 31b at a part of the inner diameter of the tubular body 21.

The second rotating shaft member 50 is a tubular shape in which the inside is horizontally penetrated by a predetermined diameter, and the rotor 32b of the second motor 32 is axially fixed to the outer circumferential surface.

The rotor 32b of the second motor 32 is axially fixed at an arbitrary position on the outer circumferential surface of the outer case 10.

At this time, the first rotating shaft member 40 is already inserted into the tubular body 21 of the fixed frame 20 so as to extend through the outer case 10 in the same manner as the first rotating shaft member 40. In order to avoid interference with the second rotating shaft member 50 provided, it is most preferable that the inner diameter of the second rotating shaft member 50 is larger than the outer diameter of the first rotating shaft member 40 passing therein.

That is, inside the tubular body 21, one side of the first rotating shaft member 40 is bearing-coupled, while the other side of the tube 21 is bearing-coupled and the first rotating shaft member 40 and the second rotating shaft member 50. ) Is to extend through the outer case 10 of the second motor 32 side to the outside, but the first rotation shaft member 40 is formed to penetrate the inside of the second rotation shaft member 50. In this case, it is most preferable that the outer diameter of the first rotating shaft member 40 penetrating the second rotating shaft member 50 is smaller than the inner diameter of the second rotating shaft member 50 so as not to receive mutual driving interference.

To this end, the inner diameter portion of the tubular body 31 into which the first rotating shaft member 40 and the second rotating shaft member 50 are inserted at the same time may be further expanded so that the inner diameter surface is formed in a single layer.

On the other hand, the first rotary shaft member 40 and the second rotary shaft member 50 penetrating or partially inserted through the tubular body 21 respectively extend through the outer case 10 so as to extend outward, in particular, the second rotary shaft member 50. The first rotating shaft member 40 penetrating the inner diameter of the to extend by more than a predetermined length to protrude.

And the rotating plate member 60 is largely comprised from the 1st rotating plate 61, the 2nd rotating plate 62, and the 3rd rotating plate 63. As shown in FIG.

At this time, the first rotating plate 61 and the second rotating plate 62 are fixed to the tip of the second rotating shaft 50, the third rotating plate 63 is made to extend further outward than the second rotating shaft member 50 1 is fixed to the tip of the rotating shaft member 40.

The first rotating plate 61, the second rotating plate 62, and the third rotating plate 63 are configured as circular plates having different outer diameters, and among them, the first rotating plate 61 and the second rotating plate 62 Both are axially supported by the second rotating shaft member 50, and the third rotating plate 63 is axially supported by the first rotating shaft member 40.

In the outer diameter surface, the first rotating plate 61 is the smallest, the third rotating plate 63 is larger than the first rotating plate 61, and the second rotating plate 62 is larger than the third rotating plate 63.

Each of these rotary plates 61, 62 and 63 has a shape such that the outer periphery is bent equally at a predetermined angle or with respect to the first rotary plate 61 and the second rotary plate 62 which are axially fixed on the same axis. The third rotating plate 63 is to face each other between the bent ends.

In addition, the first rotating plate 61 and the second rotating plate 62 are rotated at the same time by the second rotating shaft member 50 by being bonded or integrally attached to each other between the vertical plate surface, and the shaft on the first rotating shaft member 40 The third rotating plate 63 supported rotates in the opposite direction to the first rotating plate 61 and the second rotating plate 62.

Meanwhile, the chemical liquid supply member 70 is fixed to the outer case 10 adjacent to the rotating plate member 60, and one end thereof protrudes from the plate surface of the rotating plate member 60 toward the outer case 10, in particular from the plate surface of the second rotating plate 62. It is located inside the tubular guide 62a.

At this time, the spray nozzle 71 having a smaller outer diameter is provided at the end of the guide 62a side.

In this way, a plurality of injection holes 61b and 62b are formed concentrically on the first rotating plate 61 and the second rotating plate 62 on the inner diameter side of the guide 62a provided with the spray nozzle 71.

In addition, in the present invention, as shown in FIG. 3, a plurality of blades 81 are radially provided on the outer side of the rotor 31b of the first motor 31, and the outer case is outside of the blade 81. A vent hole 82 is formed at 10, and an air supply member 80 having an air hose 83 connected to an outer side of the vent hole 82 is provided.

An end portion of the air hose 83 provided outside the outer case 10 of the air supply member 80 may be provided with an adapter for connection with the chemical liquid container.

Looking at the operation of the present invention according to the above configuration as follows.

The present invention is a spray means that is provided purely separate from the chemical liquid reservoir in which the chemical liquid is stored.

In other words, the chemical liquid container provided separately is used in connection with the chemical liquid supply member 70.

Chemical bottles can be filled with ordinary water or household pesticides, but can also be filled with chemically diluted pesticides and pesticides that are highly toxic for crop cultivation.

When the power is applied to the present invention in the state in which the chemical container is connected, the driving member 30 starts to drive.

When the first motor 31 and the second motor 32 of the driving member 30 are driven, the rotor (by the electromagnetic force interacting between the stator 31a, 32a and the rotor 31b, 32b) 31b) 32b are rotated at a predetermined speed.

The rotational drive of the rotors 31b and 32b causes the first and second rotation shaft members 40 and 50 to axially support the rotors 31b and 32b to interlock at the same time. A plurality of rotating plate members 60 are fixed at the front end portion extending outwardly of the rotating shaft member 40 and the second rotating shaft member 50 to rotate simultaneously.

When the rotating plate member 60 is rotated as described above, the chemical liquid injected through the chemical liquid supply member 70 from the rear of the second rotating plate 62, as shown in FIG. 4, is applied to the second rotating plate 62 and the first rotating plate 61. It is injected through a plurality of formed injection holes (61b, 62b).

The chemical liquid injected through the injection holes 61b and 62b of the second rotating plate 62 and the first rotating plate 61 is scattered to the outer circumferential edge by the centrifugal force caused by the rotation of the first rotating plate 61. The chemical liquid that hits the third rotating plate 63 provided to face the first rotating plate 61 is scattered again by the second rotating plate 62 by centrifugal force due to the rotational action of the third rotating plate 63.

The chemical liquid scattered to the second rotating plate 62 is sprayed by ultra-fine atomizing the chemical liquid to the outside by the centrifugal force caused by the rotating action of the second rotating plate 62.

That is, as the chemical liquid passes through the third rotating plate 63 and the second rotating plate 62 from the first rotating plate 61, particles are formed in the form of very small ultra-fine particles and maintain a uniform spray amount.

At this time, the rotation direction of the third rotating plate 63 with respect to the first rotating plate 61 and the second rotating plate 62 which are fixed on the same axis may be the same, or may be reversed.

Meanwhile, the chemical liquid of the chemical liquid container may be supplied to the chemical liquid supply member 70 by a constant pressure in the container, but the supply pressure of the chemical liquid may be supplied by the compressed air supplied through the air supply member 80 as shown in FIG. 5. It can also be formed.

That is, when the rotor 31b of the first motor 31 rotates, the wind pressure of a constant pressure is generated by the blades 81 formed in the rotor 31b in large numbers.

This wind pressure is supplied to the chemical liquid container 90 through the vent hole 82 formed in the outer case 10 and the air hose 83 connected to the vent hole 82 from the outside of the blade 81.

The chemical liquid in the chemical liquid container 90 is supplied to the liquid feed pipe 71 of the chemical liquid supply member 70 by a predetermined amount by the wind pressure supplied in this way, and the chemical liquid is ejected through the nozzle 72 at the end of the liquid feed pipe 71. The fine particles are crushed by the centrifugal force of the first rotating plate 61 of the rotating plate member 60 which rotates at a high speed and pushed outward, and the particles are rotated to the third rotating plate 63 which rotates in the opposite direction to the first rotating plate 61. When you bump into it, it breaks down more finely.

The spray particles, which are broken more finely and pushed outward from the third rotating plate 63 again, collide with the second rotating plate 62 which rotates in the opposite direction to the third rotating plate 63, and then break more finely into spray particles in the form of ultra-fine particles. It is formed and sprayed to the outside.

Meanwhile, each end connected to the chemical liquid container 90 of the chemical liquid supply member 70 and the air supply member 80 is provided with an adapter having a function of a control valve so as to allow connection with the chemical liquid container, supply amount adjustment, and opening and closing. Most preferred.

The present invention operated as described above may adjust the spray amount by adjusting the frequency width of the power applied to the drive member 30, or may be adjusted by operating the control valve in the adapter as described above.

Therefore, the present invention can be easily used by simply connecting and simply connecting the chemical liquid container 90, and at the same time, it is possible to omit the spray means which is provided integrally with the chemical liquid container 90, thereby further reducing the purchase cost. Will be.

In particular, the present invention is to spray the chemical liquid in the form of ultra-fine particles, which are easy to contact pests or crops, so that the spraying amount can be easily controlled, and uniform spraying is more efficient, so that the insecticidal and control effects are more efficient.

As described above, the present invention allows the chemical liquid of the ultra-fine particles to be sprayed through the rotating plate member 60 formed of a plurality of rotating plates by driving the motor which is electrically reversely rotated to improve the spraying efficiency and the controlling efficiency. .

It also provides a very useful effect of providing more economical use while providing precise control of the spray volume and ease of use.
