Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizing device technology, and in particular to an improved air-water atomizing nozzle device. Background Technology
[0002] In industrial production, environmental dust removal, and cooling applications, air-water atomizing nozzles are widely used to mix water and gas to form atomized particles for spraying out, achieving specific process effects. However, existing air-water atomizing nozzles suffer from problems such as uneven air-water mixing, poor atomized particle stability, insufficient structural sealing, and inconvenient maintenance. For example, some devices have unreasonable water and airflow throttling control, resulting in large fluctuations in the medium pressure entering the mixing chamber, affecting the mixing effect; some devices have complex nozzle-to-body connection structures, making disassembly and assembly difficult, and their poor sealing performance easily leads to leakage, thus affecting the device's service life and atomization efficiency, making it difficult to meet the needs of high-precision atomization scenarios. Utility Model Content
[0003] To address some of the problems existing in the prior art, this utility model provides an improved air-water atomizing nozzle device. This air-water atomizing nozzle device achieves efficient and uniform air-water atomization effect by optimizing the air-water mixing structure and flow channel design, and is suitable for multiple application scenarios such as industrial spraying, agricultural irrigation, and fire extinguishing.
[0004] To achieve the above objectives, this utility model provides an improved air-water atomizing nozzle device, comprising a nozzle body, which is a hollow structure, with a plug threaded to one end. A gasket is provided between the plug and the nozzle body's connecting surface. A water inlet and a gas inlet are spaced apart on the sidewall of the nozzle body for the entry of water and gas, respectively. A water throttling nozzle is provided inside the nozzle body near the water inlet, communicating with the water inlet to form a water flow channel. An air throttling nozzle is fitted onto the outer end of the gas inlet, communicating with the inside of the nozzle body to form an airflow channel. An inner core is embedded inside the nozzle body at the end furthest from the plug, with one end of the inner core abutting against the water and air throttling nozzles. The other end of the inner core extends to the outside of the nozzle body and is connected to a nozzle head. A fastening nut is threaded to the outer end of the nozzle head and connected to the nozzle body via the fastening nut. An air-water mixing chamber is formed between the nozzle head and the inner core, communicating with the water flow channel and the airflow channel.
[0005] In operation, water enters the water flow channel through the water inlet and passes sequentially through the inlet section, throttling section, and outlet section of the water throttling nozzle. The spiral guide pattern on the inner wall of the outlet section guides the water flow. Gas enters through the gas inlet, passes through the gas throttling nozzle, and enters the nozzle body through the airflow channel. After the water and air flow merge inside the nozzle body, they enter the guide channel of the inner core. The spiral flow channel on the inner wall of the guide channel promotes the initial mixing of gas and water. The initially mixed gas and water enter the gas-water mixing chamber between the nozzle and the inner core for further mixing. Finally, the mixed gas and water are sprayed out through the atomizing nozzles evenly spaced on the outer end of the nozzle. The diameter of the atomizing nozzles is 0.8-1.2 mm, and their axis forms an angle of 0°-45° with the nozzle axis to ensure atomization effect. During the process, the gasket between the plug at one end of the nozzle body and the nozzle body, and the O-ring seal in the groove of the nozzle body side wall ensure the sealing of the device. At the same time, the nozzle is connected to the nozzle body by a fastening nut, which allows for individual disassembly and replacement for easy maintenance.
[0006] The beneficial effects of this utility model are as follows: By setting water throttling nozzles and air throttling nozzles, the water flow and air flow are stabilized and guided respectively. Combined with the flow guiding channel and spiral flow channel of the inner core, it can effectively promote the full and uniform mixing of air and water in the mixing chamber. The inlet section, throttling section and outlet section structure of the water throttling nozzle further improves the stability of the water flow and the throttling effect. The atomizing nozzle of the nozzle adopts a specific aperture and angle design to ensure uniform atomized particles and reasonable coverage. The setting of O-ring seal enhances the sealing performance of the device. At the same time, the nozzle is connected to the nozzle body by a fastening nut, which can be disassembled and replaced separately, greatly simplifying the maintenance process and reducing the cost of use. The overall structure is stable and reliable, significantly improving the atomization effect and the efficiency of the device, and extending its service life.
[0007] As a further improvement of this utility model, in order to improve the stability of water flow, enhance mixing uniformity and throttling effect, the water throttling nozzle includes an inlet section, a throttling section and an outlet section, which are connected in sequence; the inlet section has a funnel-shaped structure, with its large-diameter end connected to the water flow channel; the outlet section has a conical structure, with its small-diameter end facing the inner core; the two ends of the throttling section are respectively connected to the small-diameter end of the inlet section and the large-diameter end of the outlet section, and the inner sidewall of the outlet section is also provided with spiral guide patterns.
[0008] As a further improvement of this utility model, in order to eliminate turbulence interference and make the mixed fluid enter the mixing chamber in a spiral shape, while promoting full mixing of air and water, a flow guiding channel is provided inside the inner core. The inlet of the flow guiding channel is connected to the water throttle nozzle and the air throttle nozzle, and the other end is connected to the air-water mixing chamber. The inner wall of the flow guiding channel is also provided with several spiral flow channels distributed along the axial direction.
[0009] As a further improvement of this utility model, in order to ensure the uniformity of atomized particles and the reasonable coverage range, the nozzle and the inner core are arranged with the same axis, and the outer end of the nozzle is provided with an atomizing nozzle hole; a number of atomizing nozzle holes are evenly spaced, and the diameter of the atomizing nozzle hole is 0.8 to 1.2 mm; the axis of the atomizing nozzle hole forms an angle of 0° to 45° with the axis of the nozzle.
[0010] As a further improvement of this utility model, in order to enhance the sealing performance at the gas and water interface end faces of the device and avoid media leakage, multiple grooves are provided on the side wall of the nozzle body, and O-rings are fitted in the grooves; the O-rings are made of nitrile rubber and have a cross-sectional diameter of 2-3 mm.
[0011] As a further improvement of this utility model, in order to simplify the maintenance process and reduce the cost of use, the nozzle is connected to the nozzle body by a fastening nut, and the nozzle can be disassembled and replaced separately. Attached Figure Description
