Description

Technical Field

[0001] This utility model relates to the field of atomizing nozzle technology, specifically a dual-fluid air atomizing nozzle. Background Technology

[0002] Air atomizing nozzles are two-fluid nozzles (air and liquid), which can avoid the inherent disadvantages of mechanical nozzles, such as poor atomization at low oil pressure and oil pressure adjustment being limited by oil supply pressure. They are mainly used in industries such as spraying, disinfection, and humidification.

[0003] Existing air atomizing nozzles rely on pumps to deliver liquids, resulting in high energy consumption, complex structures, and traditional internal mixing nozzles that are prone to clogging and are difficult to use with high-viscosity or particulate liquids.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a dual-fluid air atomizing nozzle that can quickly replace different models or specifications of liquid caps and air caps to adapt to different liquid properties, flow rates or atomization requirements; it is easy to maintain; the modular design makes the disassembly and assembly process simple, greatly facilitating the cleaning, inspection and maintenance of the nozzle and reducing downtime.

[0006] To solve the above problems, the technical solution of this utility model is as follows: a dual-fluid air atomizing nozzle, including a nozzle body, a nozzle base sleeved at the bottom of the nozzle body, a partition locking ring at the upper end of the nozzle base, a washer inside the partition locking ring, a partition at the upper end of the washer, a liquid cap at the upper end of the nozzle body, a locking cap sleeved on the outside of the liquid cap, an air cap at the upper part between the liquid cap and the locking cap, the upper end of the partition located at the lower part between the liquid cap and the locking cap, and the lower end of the partition located between the nozzle body and the washer.

[0007] Preferably, one end of the nozzle base is provided with a threaded interface, and the lower end of the nozzle base is provided with a nozzle.

[0008] Preferably, a sealing ring is provided at the junction of the nozzle body and the nozzle base.

[0009] Preferably, a second sealing ring is provided at the junction of the nozzle body and the gasket.

[0010] Preferably, a sealing ring is provided at the junction of the nozzle body and the liquid cap.

[0011] Preferably, a sealing ring is provided at the junction of the partition and the liquid cap.

[0012] The advantages of this invention compared to existing technologies are as follows:

[0013] This invention adopts a siphon structure, which eliminates the need for an external pump and achieves spraying solely with compressed air.

[0014] This utility model adopts a modular design, which can quickly replace liquid caps and air caps of different models or specifications to adapt to different liquid properties, flow rates or atomization requirements;

[0015] This invention employs a straight liquid flow channel and an external mixing atomization method, which is easy to clean, prevents clogging, and can atomize liquid media with high viscosity, achieving micron-level uniform atomization.

[0016] This utility model adopts a through-plate partition installation structure design, which facilitates disassembly and maintenance. Attached Figure Description

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, a dual-fluid air atomizing nozzle includes a nozzle body 1, a nozzle base 2 fitted onto the bottom of the nozzle body 1, a sealing ring 11 installed at the junction of the nozzle body 1 and the nozzle base 2, a threaded interface 9 at one end of the nozzle base 2 connected to an external air inlet connector, a nozzle 10 installed at the lower end of the nozzle base 2 connected to an external liquid inlet connector, a partition locking ring 3 installed at the upper end of the nozzle base 2, and a washer 4 installed inside the partition locking ring 3. A sealing ring 12 is installed at the junction of the nozzle body 1 and the gasket 4. A partition 5 is installed on the upper end of the gasket 4. A liquid cap 6 is installed on the upper end of the nozzle body 1. A sealing ring 13 is installed at the junction of the nozzle body 1 and the liquid cap 6. A sealing ring 14 is installed at the junction of the partition 5 and the liquid cap 6. A locking cap 7 is installed on the outer side of the liquid cap 6. An air cap 8 is installed on the upper part between the liquid cap 6 and the locking cap 7. The upper end of the partition 5 is located at the lower part between the liquid cap 6 and the locking cap 7. The lower end of the partition 5 is located between the nozzle body 1 and the gasket 4. The design of the locking cap 7 allows for quick replacement of liquid caps 6 and air caps 8 of different models or specifications.

[0025] Working principle: The threaded interface 9 is connected to the external air inlet connector, and the nozzle 10 is connected to the external liquid inlet connector. Compressed air and liquid are connected to the water inlet and air inlet connectors. After the high-speed airflow and liquid are ejected through the nozzle, the gas and liquid phases mix outside the nozzle. The high-speed gas exerts a strong shear force and impact force on the liquid jet or liquid film, overcoming the surface tension and viscosity of the liquid, thereby realizing the atomization of the outside and the utilization of the kinetic energy of the high-speed gas. This gives the device significant advantages such as fine atomization, good adjustability, less clogging, and strong ability to handle high-viscosity liquids.
