Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable vortex generator for forming an artificial spiral vortex and its use.

[0002]

2. Description of the Related Art Conventionally, toxic gas, dust, etc. locally generated are ventilated in the whole building, or
A method has been adopted in which an exhaust hood is provided near the generation source to suck and exhaust. However, there is a time and economical problem in eliminating harmful gases and dust that are continuously generated.

Therefore, recently, there has been proposed an apparatus for artificially forming a spiral vortex to efficiently remove harmful gas, dust and the like (Japanese Patent Laid-Open Nos. 62-261842 and 64).
-19242, JP-A-2-161238,
JP-A-4-140, Japanese Patent Publication No. 3-50942, etc.).

[0004]

The above-mentioned conventional device is
It was a device fixed to a source effective only for a fixed source, and it was difficult for the source to immediately respond to movement or sudden occurrence.

It is an object of the present invention to provide a portable vortex generator capable of promptly and effectively eliminating harmful gas, dust, etc. generated by a moving source or generated suddenly, and a method of using the same. I am trying.

[0006]

According to the present invention, a double tube having an inner peripheral pipe connected to an exhaust fan and an outer peripheral pipe connected to an air supply fan is formed, and a spiral vortex is generated in the outer peripheral pipe. An outlet with means is provided.

Further, according to the present invention, the spiral vortex generated by the portable vortex generator is used for collecting welding fumes, simple dust collection, toys and teaching materials.

The vortex generating means uses a method of giving a rotational force by a plurality of blowout nozzles or guide vanes inclined in one direction in the circumferential direction, and air is supplied from the circumferential direction of the outer peripheral tube to generate a swirling flow in the outer peripheral tube. There is a method to give a turning force.

[0009]

In the portable vortex generator configured as described above, the air blown from the outer peripheral tube and rotating in the same direction is mixed with harmful gas or dust having symmetrical discharge, and is discharged by the exhaust of the inner peripheral tube. It is collected in the center by pressure and is sucked into the inner peripheral tube while forming a spiral vortex by the initial rotational force.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, an air inlet 2 is formed at one end of an inner peripheral tube 1 of a portable vortex generator A composed of a double tube, and an exhaust port 3 is provided at the other end. There is.

On the other hand, an air outlet 5 is provided on the air inlet 2 side of the outer peripheral cylinder 4, and the plurality of air outlets 5 are inclined in one direction in the circumferential direction, which is a vortex generating means (in the example shown in the drawing, the air outlet 5 is provided. 7
Individual) blowout nozzles 6 are provided in a protruding manner. In addition, the outer peripheral cylinder 4
An air supply port 7 is provided on the exhaust port 3 side. The device A is lightweight, compact and portable.

Therefore, when the air supply port 7 is connected to the air supply fan 9 (FIG. 3) and the exhaust port 3 is connected to the exhaust fan 11 (FIG. 3) and both fans 9, 11 are operated, the blowout nozzle 6 , 6 ... form a spiral vortex C and a suction flow D is generated.

FIG. 2 shows another embodiment of the portable vortex generator, in which a plurality of vortex generators (7 in the illustrated example) which are inclined in one direction in the circumferential direction, which is the vortex generator, are provided at the outlet 5A of the vortex generator A1. ) Is provided and the other parts are configured in the same manner as in FIG. 1.

FIG. 3 shows still another embodiment, which is an example in which an air supply port 7a opened in the cutting line direction of the outer peripheral cylinder 4 is provided at the other end of the outer peripheral cylinder 4 of the vortex generator A '. Therefore, the air sent from the air supply port 7 a generates the spiral vortex C in the outer peripheral cylinder 4.

FIG. 4 shows an example of an apparatus using a portable vortex generator. In this device, the air supply port 7 of the portable vortex generator A is connected to an air supply fan 9 via an air supply hose 8, and the exhaust port 3 is connected to an exhaust fan 11 via an exhaust hose 10 to exhaust the exhaust gas. The fan 11 is connected to the dust collector 12.

When both the fans 9 and 11 are operated, the suction flow D is generated by the air blown from the blowout nozzle 6 (FIG. 6) and mixed with the dust E, and the suction negative pressure of the inner peripheral pipe 1 causes the spiral flow F.
Is sucked into the inner peripheral tube 1 and the dust E is collected by the dust collector 12.

FIG. 5 shows an embodiment of the use of the portable vortex generator of the present invention, that is, an example of collecting welding fumes. Portable vortex generator A with built-in blower (not shown)
This is an example in which the spiral vortex C from 2 is mixed with the welding fumes G, absorbed by the purification device 13 having an exhaust fan (not shown), purified, and exhausted.
