Description

Turbo compressor using mass applied liquid

The present invention relates to a turbo compressor using a mass-applied liquid, and more particularly, in the rotation of an impeller in which a plurality of vent holes are formed, gas and mass-applied liquid are periodically injected into the vent holes to form a liquid column between the air zones. The present invention relates to a turbocompressor using a mass-applied liquid in which high-pressure air is produced by pressing a gas at the front end by maintaining a high speed rotation of the impeller with an increased centrifugal force due to the liquid column.

Compressor is a device that obtains high pressure gas by applying mechanical energy (pressure, velocity) to the gas drawn from the outside to reduce the volume of the gas, and converting the mechanical energy into pressure. have. The compressor is used in various industrial tools such as various air tools, air brushes, air cylinders.

However, a commonly used low volume compressor uses a simple compression method that relies on piston reciprocating motion. As described above, the compression pulsation is caused by the number of pistons and the reciprocating cycle time when the air is compressed.The vibration and noise caused by friction when the piston is moved up and down are not only large, but also the compression cycle is not possible because the rotational cycle cannot be fast due to structural limitations. Slow and increased frictional loss has had a problem of low energy efficiency.

In addition, the screw method used in the medium and large compressors requires high-level technology for the processing of a special shape of the screw shape, and the manufacturing cost is high, and the cooling device is required because high heat is accompanied by excessive size of the screw friction area.

The housing 100 has a space formed therein, and the interior space of the housing 100 is sealed to the outside. In addition, the housing 100 is preferably formed in a cylindrical shape to facilitate the rotation of the circular impeller 300 to be described later.

Meanwhile, the first O-ring 120 and the second O-ring 130 are formed in the housing 100. The first O-ring 120 is fitted to the coupling surface of the housing 100 and the drive shaft 210 to be described later, the second O-ring is fitted to the coupling surface of the housing 100 and the gas suction pipe 400 to be described later It serves to seal the internal space of the housing 100.

The drive motor 200 is operated by receiving power from the outside, and the drive shaft 210 is formed in the center to transmit the rotational force. In addition, the drive shaft 210 is coupled to the impeller 300 to be described later to transfer the rotational force of the drive motor 200 to the impeller 300. That is, the impeller 300 is connected to the drive motor 200 as a load. On the other hand, the drive motor 200 is preferably a high frequency motor that is rotated at a high speed of 5000RPM or more so that the high-pressure air is compressed.

Impeller 300 is installed in the housing 100, the vent hole 310 is formed radially from the center. The central portion of the impeller 300 is coupled to the drive shaft 210, the impeller 300 is rotated as the drive shaft 210 is rotated. As described above, as the impeller 300 is rotated, the air introduced into the vent hole 310 is accelerated in the circumferential direction by the centrifugal force of the cross-injected mass or the liquid (having about 780 times the mass of the air). And compressed. Therefore, the rotational resistance of the impeller is generated minutely, and accordingly, high-speed air is produced in large quantities because the high speed rotation of the impeller is maintained.

* Specific gravity of air: 0.00128 (g / cm 3)

* 4 ℃ specific gravity of water: 1 (g / cm3)

On the other hand, the impeller 300 may be provided in a plurality of up and down direction with another impeller (not shown) having the same configuration as the impeller 300. If it is assumed that the number of the impeller 300 is two, another impeller receives the high pressure air discharged from the impeller 300 is compressed in the same manner as the impeller 300. In other words, it is compressed two times to obtain more powerful compressed air.

The gas suction pipe 400 is installed in the housing 100 and is connected to the vent hole 310. As described above, the suction force is generated inside the housing 100 as the impeller 300 is rotated, so that outside air flows into the center of the vent hole 310.

On the other hand, the gas suction pipe 400 is formed with a soundproof filter 410, the soundproof filter 410 serves to filter the dust or foreign matter of the external gas is sucked and the noise generated inside the housing 100 outside It serves to be released. The sound filter 410 is preferably a material such as zeolite, activated carbon-based synthetic resin so that it can be washed after use and permanently used.

The liquid chamber 500 communicates with the housing 100, and a mass applying liquid is stored in the liquid chamber 500. The anti-freeze and the anti-corrosive material and the anti-corrosion material are mixed so that the mass-applied liquid stored in the liquid chamber 500 does not freeze even at low temperatures, and the movement path of the mass-applied liquid is not corroded in series due to the corrosion of the mass or liquid. It is preferable.

In addition, the mixing ratio of the antifreeze of the mass-applied liquid and the anticorrosive material and the anticorrosion material may vary depending on the driving environment. In general, it is preferable to mix the antifreeze 90 mass% with the anticorrosive and the anticorrosive mixture 10 mass%.

The liquid injection pipe 600 connects the gas suction pipe 400 and the liquid chamber 500, and serves to introduce the mass-applied liquid stored in the liquid chamber 500 into the gas suction pipe 400. In addition, the liquid injection pipe 600 is provided with a pump (P), the pump (P) serves to introduce the mass-applied liquid stored in the liquid chamber 500 into the gas suction pipe (400). .

Next, with reference to Figure 5 will be described the movement of the mixer consisting of a mass applied liquid and gas introduced into the impeller 300.

When a mass application liquid is continuously injected into the gas suction pipe 400, the number of the vent holes 310 per revolution of the impeller 300 is n in the radial bend holes 310 arranged at regular intervals. That is, a mass applied liquid of 1 / n is piled up with air in a predetermined band between the air layers sucked into the vent hole 310. Accordingly, the inside of the vent hole 310 is increased in mass than when only gas is introduced.

Therefore, since the impeller 300 has a mass M increased (780 / n) by the mass or the liquid, the centrifugal force (CF = M * R * V2, CF: centrifugal force M: mass) is compared with the rotational force of the same motor. R: radius V: angular velocity) is generated larger (about 20 to 30 times).

In addition, the mass-applied liquid discharged from the vent hole 310 is stored in the liquid chamber 500 that is in communication with the lower portion of the housing 100 by its own weight, the gas is inside the high-pressure container 700 to be described later Compressed and stored on. That is, the mass application liquid is circulated and used.

The high pressure vessel 700 is compressed and stored in the high pressure air generated inside the housing 100 through the gas discharge pipe 710 communicated with the housing 100. As described above, the compressed air stored in the high pressure container 700 is used for various purposes in the industrial field.

Meanwhile, as shown in FIG. 4, the liquid inflow prevention jaw 110 is formed on the bottom surface of the housing 100. In addition, the liquid inflow prevention jaw 110 surrounds the outside of the gas discharge pipe 710 and prevents the mass-applied liquid discharged from the vent hole 310 from flowing into the high-pressure container 700. do.
