Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a cleaning method for cleaning a particularly soft object to be cleaned by jetting a mixture of compressed air and high-pressure water. When air is sprayed onto an object to be cleaned through a nozzle, a small amount of water is attracted to the air jet and mixed with the water for cleaning.

(Problems to be Solved by the Invention) This conventional cleaning method requires high-pressure compressed air when cleaning, and as high-pressure compressed air is constantly jetted out from the nozzle, a large amount of compressed air is required. Therefore, large compressors are installed, which increases equipment costs and operating costs.
In particular, there were many problems such as noise pollution and vibration pollution.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cleaning method using a mixed jet of compressed air and pressurized water that eliminates one or more of the problems of conventional methods.

(Means for solving the problem and its effect) In order to achieve this object, the present invention has the following configuration.

That is, the cleaning method according to the present invention uses a mixed jet of compressed air and pressurized water.a. The sound of compressed air jet is covered by a pressure water jet curtain around the area, thereby providing a soundproofing and silencing effect.

b. The expansion of the compressed air is prevented through the surrounding pressure water curtain, and at the same time, the compressed air and pressure water collide with the object to be cleaned at high speed, achieving efficient cleaning results.

(Example) Embodiments of the invention will be described with reference to the drawings.

FIG. 1 is a structural diagram of a set of nozzles (1) according to the present invention, and the nozzle (1) has a pressure water nozzle (2
) (hereinafter abbreviated as water nozzle (2)) and a compressed air nozzle (3) (hereinafter air, abbreviated as nozzle (3)) inside this are fixed in a fixed position with their jet ports in the same direction, A water passage is formed in the space (4) between the water nozzle (2) and the air nozzle (3), and the pressure washing water flows at high speed in the direction of the arrow (6) and is jetted from the spout (8). . Compressed air flows inside the air nozzle (3) (5) in the direction of the arrow (7),
Compressed air and pressurized water are injected from the jet port (9) and can be freely turned on and off via each valve.

When cleaning an object to be cleaned, pressurized water is simultaneously injected from a water nozzle (2) and compressed air from an air nozzle (3), with the nozzle (1) pointing in the desired direction from an appropriate position around the object. Then, the object to be cleaned is cleaned to every corner through the impact force of both of them.

Conventional cleaning methods mainly use either pressurized water or compressed air; for example, when washing edible vegetables, using pressure water may damage the vegetables. Also, when compressed air is used,
Normal pressure, for example 7kg/n? In this case, the atmospheric pressure is low and work efficiency is poor, so it is necessary to increase the atmospheric pressure to 9 kg/rrr. Increasing the atmospheric pressure in this way increases the noise generated during injection.

This noise causes pollution and becomes a problem.

This invention solves the two main problems mentioned above.

The pressurized water injected from the water nozzle (2) is injected into a substantially cylindrical shape by the injection port (8), and compressed air is injected into this cylindrical water bottle from the air nozzle (3). Due to the structure, the noise caused by the injection of compressed air is The noise problem is almost eliminated by properly muting the sound. In addition, at an appropriate position at the tip of the nozzle (1), the high-pressure high-speed water and high-speed air mix to form fine, soft, high-speed wood particles that impact the object to be cleaned, creating an appropriate impact force, especially for cleaning soft vegetables, etc. It has suitable characteristics.

Figure 2 shows the tip (12) of the water nozzle (2) of the nozzle (1).
) and the tip (13) of the air nozzle (3) (14), (
15) and fixed it back and forth, and the injection angle of the air-mixed water was changed.

FIG. 3 shows an example of the shape of the injection port of the nozzle (1), where A shows an air injection port (9) formed in the center;
A plurality of pressurized water injection ports (16) are arranged around this area. B, is 2 around the air injection port (9) in the center.
Heavy pressure water injection ports (8) and (17) are formed. C1 has intermittent holes (18) bored around the air injection port (9) in the center.

Although the nozzle (1) explained above is one state,
This effect can be improved by appropriately arranging and cleaning two or more nozzles (1). Also, apply pressure water to the nozzle (3)
Needless to say, the object to be cleaned can be cleaned by spraying compressed air from the nozzle (2).

(Effects of the Invention) a. Since the pressure of the compressed air can be low, the injection noise is small and is muffled by the surrounding pressure water, causing it to become soft.

b. Therefore, the compression noise of the compressor is low, and the vibration and vibration noise are also low.

C1 Soft high-speed water droplets make it particularly suitable for cleaning soft vegetables.
