2 is an exploded perspective view showing an embodiment of the present invention.
3 is a side view showing an embodiment of the present invention.
4 is a plan view showing an embodiment of the present invention.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, which is an exploded side view showing an embodiment of the present invention, and FIG. 2, which is an exploded perspective view showing an embodiment of the present invention, a mixed fluid jet nozzle according to an embodiment of the present invention includes an inner unit 10 , An intermediate unit 20, an external unit 30, and a connection unit 40

The inner unit (10) has a tubular first fluid channel (11) formed in the longitudinal direction. In the present specification, the term "tubular" means that the through-hole is formed in the longitudinal direction so that the cross-section at an arbitrary point in the longitudinal direction has an inner diameter and an outer diameter, and the inner diameter or outer diameter does not have to be constant in the longitudinal direction.

The inner unit 10 is inserted into the tubular intermediate unit 20 and not inserted tightly but inserted between the outer circumferential surface of the inner unit 10 and the inner circumferential surface of the intermediate unit 20 with a clearance. The intermediate unit 20 is inserted into the tubular outer unit 30 and is inserted not so tightly but with a gap between the outer circumferential surface of the intermediate unit 20 and the inner circumferential surface of the outer unit 30. [

3, which is a side view showing an embodiment of the present invention, and FIG. 4, which is a plan view showing an embodiment of the present invention, the internal unit 10 and the intermediate unit 20, and between the intermediate unit 20 and the outer unit 30, an elongated space having an annular cross section is created, and the two spaces become the second fluid passage. That is, the elongated space of the annular cross section due to the clearance between the inner unit 10 and the intermediate unit 20 becomes the inner second fluid passage 21 and the space between the intermediate unit 20 and the outer unit 30 And the elongated space of the annular cross section due to the clearance serves as the external second fluid passage 31.

With this configuration, when the mixed fluid injection nozzle according to the present embodiment is used, when the second fluid pressurized by the inner second fluid flow path 21 surrounding the first fluid flow path 11 is supplied, The first fluid is discharged through the one fluid channel 11 and the discharged first fluid and the second fluid supplied from the second fluid channel 21 are mixed while being mixed with each other. The shape and the mutual position of the first fluid channel 11 and the second fluid channel 21 and the shape and the structure of the inner unit 10 and the intermediate unit 20, It will be apparent to those skilled in the art that various changes may be made.

Also, the pressure of the pressurized second fluid supplied to the external second fluid channel 31 surrounding the outside of the internal second fluid channel 21 is also partially regulated by the discharge of the first fluid through the first fluid channel 11 , And some are used to improve the degree of mixing of the first fluid and the second fluid and to increase the mixing distance of the mixed fluid.

The case where the second fluid is supplied to the single second fluid channel at the same flow rate and pressure and the case where the second fluid is supplied to the two second fluid channels 21 and 31 by dividing the flow rate as in the embodiment, As a result, in the latter case, mixed mixed fluid was injected farther and farther, and it was possible to inject by the discharge and mixing of the second fluid even at a lower pressure than that of the former case.

In other words, when the same second fluid supply source is used, the mixed fluid can be injected up to a long distance compared to the conventional case, and when mixed with the same second fluid supply source, the mixed fluid can be injected better mixed than the conventional case. This means that the operation can be performed even when the pressure provided by the second fluid supply source is lowered compared with the prior art, and the apparatus adopting the mixed fluid injection nozzle can be miniaturized, the mobility can be improved, and the energy can be saved.

It is also possible that the inner second fluid passage 21 and the outer second fluid passage 31 are completely separated from each other to receive a second fluid from a separate second fluid source, The inner second fluid channel 21 and the outer second fluid channel 31 are preferably communicated with each other. In this specification, the term 'shear' refers to a direction in which a fluid flows, and a portion through which a fluid first passes is referred to as a 'front end', and a portion through which a fluid passes last corresponds to a 'rear end'.

The inner and outer second fluid flow paths 21 and 31 may be smoothly formed without irregularities. However, one or more of the inner and outer second fluid flow paths 21 and 31 may be formed in at least one of the inner second fluid flow path 21 and the outer second fluid flow path 31 Or more of the spiral guides 12 and 22 so that the fluid can form a vortex by the spiral guides 12 and 22 is more preferable in terms of mixing degree and spray distance as compared with the case where the spiral guides 12 and 22 are not vortexed.

The helical guides 12 and 22 may be formed on the outer circumferential surface or the inner circumferential surface of the units 10 and 20 and 30 and the helical guides 12 and 22 may be formed in the inner second fluid passage 21 The helical guide 12 of the intermediate unit 20 is formed on the outer circumferential surface of the inner unit 10 and the helical guide 22 inside the outer second fluid passage 31 is formed on the outer circumferential surface of the intermediate unit 20 But is not limited thereto.

When the helical guides 12 and 22 are present, the helical guides 12 and 22 form a gap between the inner unit 10 and the intermediate unit 20 and between the middle unit 20 and the outer unit 30 Thereby enabling the flow of the fluid. That is, since the upper surfaces of the helical guides 12 and 22 are in contact with the inner circumferential surfaces of the units 20 and 30 on the outer sides thereof, the fluid can flow while the units are not completely filled.

Even if the heights of the helical guides 12 and 22 are lowered so that the inner circumferential surfaces of the units 20 and 30 on the outer side thereof are not in contact with the upper surfaces of the helical guides 12 and 22, 22a formed on the inner circumferential surfaces of the units 20, 30 located on the outer sides of the projections 12a, 22a formed on the outer ends of the protrusions 12a, 22a are engaged with the engaging protrusions 23, 23 and 33, the depths of insertion of the units 10 and 20 in which the helical guides 12 and 22 are formed are limited, thereby securing clearance between the units.

Although the internal unit 10, the intermediate unit 20, and the external unit 30 described above are provided, there is no problem in functioning as the mixed fluid jetting nozzle disclosed in the present specification. However, in the embodiment, (40).

As shown in detail in FIG. 1, the connection unit 40 has a rear end connected to the front end of the outer unit 30 to become an assembly. The connection unit 40 includes a first fluid supply port 41 on one side, A fluid supply port (42) is formed, and a second fluid discharge portion (44) for discharging a second fluid supplied from the second fluid supply port (42) is formed at one side of the first fluid supply port A first fluid discharge portion 43 for discharging a first fluid to be supplied is formed at an inner side of the inner unit 10 and an intermediate unit 20 is inserted into the outer unit 30, The second fluid ejecting portion 44 is provided at the front end of each of the inner second fluid passage 21 and the outer second fluid passage 31 by fastening the front end and the rear end of the outer unit 30, And the first fluid discharge part 43 is coupled to the front end of the first fluid flow path 11. [

The first fluid can be discharged out of the nozzle through the first fluid supply port 41, the first fluid discharge portion 43 and the first fluid flow path 11 and the second fluid can be discharged through the second fluid supply port 42 And an outer second fluid passage 31 and an inner second fluid passage 21 supplied through the second fluid discharge portion 44 and connected to the second fluid discharge portion 44 at the front end thereof, .

 Thus, when the second fluid pressurized by the inner second fluid channel 21 surrounding the first fluid channel 11 is supplied, the first fluid is discharged through the first fluid channel 11 by the pressure And the discharged first fluid and the second fluid supplied from the internal second fluid passage 21 are mixed while being mixed with each other. Also, the pressure of the pressurized second fluid supplied to the external second fluid channel 31 surrounding the outside of the internal second fluid channel 21 is also partially regulated by the discharge of the first fluid through the first fluid channel 11 And a part thereof is used to improve the mixing degree of the first fluid and the second fluid and increase the mixing range of the mixed fluid so as to increase the mixing degree of the mixed fluid as a whole and to increase the mixing range.

Reference numeral 45 denotes a fastening hole formed on the connecting unit 40 for fastening the mixed fluid jet nozzle assembly to the main body of the apparatus employing the mixed fluid jet nozzle by bolts or the like.
