Description

Mixed fluid spray nozzle with rotating unit {MIXED FLUID SPRAY NOZZLE HACING ROTATION UNIT}

The present invention relates to a mixed-fluid injection nozzle having a rotating unit, and more particularly, to a mixed-fluid injection nozzle having a rotating unit for atomizing and discharging a low-pressure fluid by using a high-pressure fluid.

In general, the mixed fluid spray nozzle strongly sprays liquid in the form of mist through a spray hole formed in the front of the nozzle, and is used for various purposes where humidity or temperature control is required, such as fruit trees, mushroom cultivation houses, washing machines and drying rooms.

The mixed fluid nozzle uses the pressure of the second fluid to discharge the first fluid, and is a nozzle that mixes and sprays the first fluid and the second fluid. Here, the first fluid may be formed of a liquid such as water or a chemical solution, and the second fluid may be formed of a gas such as air or steam.

The mixed fluid injection nozzle uses a high pressure second fluid to atomize and atomize the first fluid, and for this purpose, a compression tank or a compression pump is used. In order to provide the second fluid having a sufficiently high pressure, there is a problem that a pump having a large volume and high power consumption must be used.

Accordingly, there is a need to develop a nozzle capable of stably atomizing and spraying the first fluid using a low power pump.
