Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water droplet atomization device, and more particularly to a water droplet atomization device equipped with a water spray device and a water droplet collision device.

A conventional water droplet atomization device is shown in FIG. In the figure, an upper casing 10 of a water droplet atomization device 1 is shown.
A blower 11 is disposed in the opening 1A of the blower 11, and the blower 11 is rotationally driven by a drive device 12 located below the blower 11. The drive device 12 is disposed through the partition plate 13 and has its drive shaft 12 in the lower casing 19.
The other end protrudes, and the drive shaft 12 is connected to the water suction pipe 1.
6. The lower end of the water suction pipe 16 is immersed in a water receiving tank 18, and water is sucked up by rotation of the water suction pipe. Water suction pipe 1
A rotating disk 15 is provided on the upper part of the rotating disk 6, and an eliminator 17 is fixed around the rotating disk 15. Water sucked up from the water tank 18 by the water suction pipe 16 is sprinkled by the rotating disk 15, collides with the eliminator 17, and is atomized. These fine water droplets are discharged from between the lower casing 19 and the partition plate 13 by the air supply A. On the other hand, the air 1B that has entered the water droplet atomization device 1 from the blower 11 is discharged from between the upper casing 10 and the partition plate 13, but this is mixed with the air A as secondary air and enters the target space. It's blown out.

The above device has a drawback that if the rotating disk 15 is made larger in order to increase the amount of water sprayed, the water spray becomes uneven and it becomes difficult to make the water droplets fine. As a result, the structural dimensions were limited, and for example, the maximum amount of microdroplets generated per unit was only about 20/hr. Therefore, if more microscopic water droplets are required, multiple water droplet atomization devices must be installed, which requires a large installation space and has drawbacks such as increased power costs. Ta.

SUMMARY OF THE INVENTION An object of the present invention is to provide a water droplet atomization device that eliminates the drawbacks of the prior art and is capable of generating a large amount of microdroplets with a single device.

The present invention makes use of the fact that water droplets become fine when they collide with an object, and a needle-like protrusion is provided on a shaft rotated by a drive device, and water droplets collide with the needle-like protrusion to make water droplets fine. It is structured so that it becomes

That is, the present invention comprises a water spraying means for spraying a liquid into the tower, and a spraying liquid collision means provided near the watering means, and the liquid collision means is suspended on the inner wall of the tower via a bearing. The present invention is characterized in that it includes a rotary shaft, a drive means for the rotary shaft, and rotary vanes with protrusions attached radially to the rotary shaft.

Hereinafter, the present invention will be explained in more detail with reference to the drawings. FIG. 2 shows an embodiment of the water droplet atomization device according to the present invention.

In the figure, a tower body 5 that constitutes a water droplet atomization device is shown.
A water sprinkling pipe 54 is provided inside the water sprinkling pipe 54.
A rotating shaft 55 is suspended below the side wall of the tower body 50 via a bearing 57. This rotating shaft 55 is provided with a large number of radial blades 56 to which needle-like protrusions 56A are attached. In addition, this rotating shaft 5
5 is connected to an external drive device 58 so that it can be rotated. An air suction port 60 having a blower 51 is provided on the lower side wall of the tower body 50, and the bottom of the tower body 50 forms a water receiving tank 59.
The water receiving tank 59 is connected to a water sprinkler pipe 54 via a water pipe 52 and a pump 53. Also, tower body 5
An air outlet 61 is provided at the top of the 0.

In the above configuration, water pumped by the pump 53 passes through the water pipe 52 and is sprayed from the sprinkler pipe 54 into the tower. This sprayed water is transferred to a blade 5 attached to a rotating shaft 55 rotated by a drive device 58.
6. It collides with the protrusion 56A and becomes fine. The water that has not been atomized falls into the water receiving tank 59 and is supplied to the sprinkler pipe 54 again. On the other hand, the air C sucked into the casing from the air suction port 60 by the blower 51 conveys fine water droplets to the discharge port 60.
is discharged from.

According to the above embodiment, by increasing the rotational speed of the drive device 58, the number of collisions between the water falling from the sprinkler pipe 34 and the protrusion 56A of the blade 56 is increased, so that a large volume of water droplets can be produced with one device. Can be miniaturized. In addition, the water that has not been atomized is returned to the water tank 59 and recirculated to the sprinkler pipe 54, so that the water can be used effectively.

In the above embodiment, the water sprinkling means is the water sprinkling pipe 54, but it may also be a spray nozzle. Although the water sprinkling means was provided on the upper part of the rotating shaft provided with the protrusion, it may be provided on the lower part or side of the rotating shaft. Moreover, instead of using a circulating type of water, a discharge type may be used.

As explained above, according to the present invention, water droplets are made fine by the collision between the needle-like protrusions and the water spray, so that it is possible to generate a large amount of fine water droplets with one device.
