In order to mix the liquid with gas and spray it so that the liquid can be supplied in a uniformly dispersed state with a small particle size, the present invention has a tapered inner surface that becomes smaller in diameter toward the discharge port. A liquid ejection nozzle is disposed in a nozzle body formed close to the nozzle body, with a gas ejection path formed around the nozzle, and a gas-liquid mixing space formed in front of the nozzle, and further provided with the ejection port. This invention relates to a spray nozzle arranged so that liquid is ejected toward the side. In the conventional nozzle of the above type, for example,
When trying to adjust the particle size of the sprayed liquid to the set state, the amount of liquid sprayed per unit time by one nozzle cannot be increased unless the amount of gas to the amount of liquid (gas-liquid ratio) is increased. In order to reduce the initial and running costs for gas supply by keeping the liquid ratio low, if a large amount of liquid is required to be sprayed, a large number of nozzles must be installed.
In addition to the high cost of the equipment required to install the nozzle, the probability of occurrence of troubles such as clogging is high, resulting in troublesome maintenance. Furthermore, even if the amount of liquid sprayed per unit time is relatively small, if the particle size of the sprayed liquid needs to be extremely small, the gas-liquid ratio must be extremely large, and as a result, the air A large-sized gas supply device such as a compressor must be provided, and both the equipment cost and operating cost for gas supply are high, making it uneconomical. Furthermore, with conventional nozzles, no matter how much you increase the gas-liquid ratio while keeping the liquid spray amount constant, once the gas-liquid ratio increases beyond a certain level, the change in particle size becomes minute, resulting in only relatively large particle sizes. On the other hand, no matter how much you increase the gas-liquid ratio while keeping the particle size constant, if the gas-liquid ratio increases beyond a certain level, the change in the amount of liquid sprayed per unit time becomes small, making it difficult to compare. Only a relatively small amount of liquid could be sprayed, and there were limits to both the reduction in particle size and the increase in the amount of liquid sprayed per unit time. In view of the above points, the present invention aims to increase the amount of liquid sprayed by one nozzle while maintaining a predetermined sprayed liquid particle size and suppressing an increase in the gas-liquid ratio. It is possible to reduce the particle size of the sprayed liquid while maintaining a predetermined spray amount by the nozzle and suppressing an increase in the gas-liquid ratio.
It is an object of the present invention to provide a nozzle that can perform liquid spraying advantageously from both economical and maintenance standpoints. Next, embodiments of the present invention will be described in detail based on illustrative drawings. A hose 2 that is connected to a gas supply device 1 such as an air compressor is connected to a nozzle body 4 via a connector 3 equipped with a check valve, and on the other hand is connected to a liquid supply device 5 such as a pump.

It is connected to a liquid jetting nozzle 8 through a connecting fitting 7 equipped with a check valve, and the jetting nozzle 8 is fitted into the nozzle body 4, so that, for example, water can be sprayed onto a rolled steel material. A spray nozzle used for supplying, cooling, etc. is configured. As shown in FIG.
The cap 1 is sealed with the second main body portion 4b formed with the tapered inner surface portion 11 whose diameter becomes smaller toward the discharge port side through the packing 12.
3 are integrally connected by screwing into the first main body portion 4a. The ejection nozzle 8 has a first
It is composed of a nozzle portion 8a and a second nozzle portion 8b provided with a discharge port 15, and the first nozzle portion 8a is provided in the first body portion 4a and extends inwardly from the first body portion 4a. , a flange portion 17 in which communication holes 16 are formed at predetermined intervals in the circumferential direction.
On the other hand, a pair of flange portions 18, 18 are provided on the second nozzle portion 8b outwardly at a predetermined phase portion in the circumferential direction.
and the flange portions 18, 18 of the second
The second nozzle portion 8b is attached to the first nozzle portion 8a by fitting and locking the second nozzle portion 8b into the first nozzle portion 8a by abutting and locking the cap 13 into the recessed portion 19 formed in the main body portion 4b.
It is configured to be integrally connected in a sealed state through the. Therefore, by attaching and detaching the cap 13, the second main body portion 4b and the second nozzle portion 8b can be assembled and disassembled all at once, and foreign matter clogging the discharge ports 10 and 15 can be easily removed. When the ejection nozzle 8 is fitted into the nozzle body 4, a gas ejection path R is formed between the nozzle body 4 and the ejection nozzle 8, and both ejection ports 10,
A gas-liquid mixing space S is formed between 15 and 15, and gas is supplied and mixed with the liquid jetted from the discharge port 15 of the jet nozzle 8 toward the discharge port 10 of the nozzle body 4. The liquid is configured to be sprayed to the outside from the discharge port 10 of. As shown in FIG. 3, each of the discharge ports 10 and 15 has a pair of elongated opening portions 2 extending in the radial direction.
1 and 21 are arranged in a straight line substantially on the ejection center line, and the ejection port 10 of the nozzle body 4 and the ejection port 15 of the jet nozzle 8 are 90 degrees out of phase with each other when viewed in the direction of the ejection center, that is, viewed from the outlet. The particles are arranged at different sizes, so that the amount of liquid sprayed per unit time can be increased and the spray range can be expanded without increasing the particle size. To form both the discharge ports 10 and 15, for example, as shown in FIG. 5, the opening portions 21 are arranged approximately on the discharge center line, and are formed radially in four directions with a phase difference of 90 degrees. And both discharge ports 10,1

When looking at the amount of water supplied to obtain a predetermined particle size,
In the nozzle of the present invention, compared to conventional nozzles,
It is clear that the amount of water can be supplied from several times to more than ten times. FIG. 6 is a graph showing the maximum particle size and gas-liquid ratio extracted from the above data for the nozzle of the present invention, and shows that the nozzle of the present invention is distributed within the curve a-a'. It shows. In this graph, for example, if we extract two points P 1 and P 2 with a maximum particle size of 70 μm, the amount of water supplied per minute at P 1 is 1800 c.c., and at P 2 it is 1860 c.c. .In comparison, the maximum particle size located within the curve a-a' in the conventional nozzle
Regarding Q in the case of 72 μm, it is clear that the amount of water supplied per minute is 150 c.c., which is an extremely small amount less than 1/10 of that of the present invention. Note that the present invention is not limited to the nozzle used for cooling steel materials during rolling as described above.

Consisting of a plurality of openings 21..., the discharge port 10 of the nozzle body 4 and the discharge port 15 of the liquid jet nozzle 8 are arranged so that the phases of the openings 21 are different when viewed in the direction of the discharge center. It is characterized by certain things. In other words, the plurality of elongated opening portions 21..., 21...
A nozzle body 4 and a liquid jet nozzle 8 composed of
By arranging the respective discharge ports 10 and 15 with different phases from each other, it is possible to improve the mixing performance in the gas-liquid mixing space S, and as described in detail earlier, the same spray as the conventional nozzle can be obtained. In order to obtain the liquid droplet size, it is necessary to make the gas-liquid ratio much smaller than before compared to the amount of liquid sprayed per unit time by one nozzle, or to obtain an extremely large amount of liquid that cannot be obtained with conventional nozzles. can be sprayed with one nozzle, and when the amount of liquid sprayed per unit time by a conventional nozzle and one nozzle is the same, the gas-liquid ratio is low considering the sprayed liquid droplet size. It has become possible to make the spray liquid much smaller than before, and to obtain spray liquid with extremely fine particle sizes that cannot be obtained with conventional nozzles. In summary, it can sufficiently respond to the wide range of spray droplet diameters and changes in liquid spray volume that are required, and can also increase the volume of liquid spray per nozzle to reduce nozzle installation costs and avoid trouble. Moreover, the gas supply device can be made smaller to reduce its initial cost and running cost, and an extremely effective spray nozzle can be obtained as a whole.
