Description

Technical Field

[0001] This utility model relates to the field of atomizing nozzles, and in particular to a dual-channel nozzle structure for mechanical and media mixing atomization. Background Technology

[0002] "Atomization" usually refers to a process of turning a liquid into tiny water droplets or mist. Mechanical and media mixing atomization refers to the process of mixing and atomizing a liquid with a gas (usually air) through mechanical means (such as nozzles, stirrers, etc.).

[0003] A search revealed Chinese Patent Publication No. CN221996310U, which discloses a dual-channel atomizing nozzle. The nozzle includes a spray pipe, one end of which is sealed, and the other end is detachably connected to a connector for introducing two fluids. A partition plate is provided inside the spray pipe to divide its interior into a first cavity and a second cavity. A cover is also provided on the outer wall of the spray pipe, forming a mixing chamber between the cover and the outer wall. Through holes are provided on the side wall of the spray pipe to connect the mixing chamber with the first and second cavities. At least one nozzle is provided on the cover. This invention can improve the atomization effect of agricultural spraying. Because this invention does not utilize the special structure of the nozzle to atomize water, but rather uses a water-air mixed spray method for atomization, it can achieve a high atomization effect without being limited by the nozzle structure.

[0004] The aforementioned device, although atomizing through water-air mixing and spraying, has two separate channels for liquid and gas, which enter the mixing chamber between the nozzle and the cover from opposite sides of the nozzle. Furthermore, nozzles are located on the sides of the cover. This introduces a risk that the gas and liquid may not be fully mixed before being ejected through the nozzles. Additionally, if the nozzle needs to spray in all directions, more nozzles need to be installed at multiple angles on the cover surface, further increasing the risk of uneven gas-liquid mixing and hindering effective atomization. Therefore, this device is not practical. To address these issues, a dual-channel nozzle structure for mechanical and media mixing atomization is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dual-channel nozzle structure for mechanical and media mixing and atomization. It aims to improve the problem in the prior art that if the nozzle needs to spray in all directions, more nozzles need to be set at multiple angles on the surface of the cover, which will further increase the risk of uneven gas-liquid mixing and make it impossible for the nozzle to atomize the liquid well.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dual-channel nozzle structure for mechanical and media mixing and atomization, comprising a shell, an air inlet pipe fixedly connected to the left bottom surface of the shell, a liquid inlet pipe fixedly connected to the right bottom surface of the shell, a spraying assembly provided on the upper part of the shell, a connecting cavity provided on the lower part of the shell, an atomizing cavity provided on the upper part of the connecting cavity, an installation groove provided on the top of the atomizing cavity, and a uniform material plate fixedly connected to the middle part of the atomizing cavity.

[0007] As a further description of the above technical solution:

[0008] The uniform material plate has fine holes in the middle.

[0009] As a further description of the above technical solution:

[0010] The lower part of the atomizing chamber is provided with a diffusion trough, and the upper part of the atomizing chamber is provided with a gathering trough.

[0011] As a further description of the above technical solution:

[0012] The top of the outer casing has an annular groove.

[0013] As a further description of the above technical solution:

[0014] The spraying assembly includes a mounting plate, and a connecting cone is fixedly connected to the bottom surface of the mounting plate.

[0015] As a further description of the above technical solution:

[0016] A connecting ring is fixedly connected to the bottom surface of the mounting plate, and the connecting ring is rotatably connected to the ring groove.

[0017] As a further description of the above technical solution:

[0018] The connecting cone is externally fixedly connected with multiple spiral plates.

[0019] As a further description of the above technical solution:

[0020] The mounting plate has multiple spray chambers in the middle, which are sequentially opened between two adjacent spiral blades. Spray nozzles are opened on the side of the multiple spray chambers that are far apart from each other.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up the cooperation between the outer shell, the spraying component, the uniform plate, the connecting cavity, the atomizing cavity and other components, the device can achieve full mixing between gas and liquid, thereby ensuring the atomization effect of the nozzle and making it more practical.

[0023] 2. In this utility model, the spraying nozzle can achieve multi-angle spraying by the cooperation between components such as the spraying chamber and the spraying port. At the same time, by the cooperation between components such as the connecting cone and the spiral blade, the connecting cone and the mounting plate can be rotated by the spiral blade when the gas-liquid mixture is transported outward, thereby making the atomization spraying range of the nozzle wider and more practical.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2The present invention provides an embodiment of a dual-channel nozzle structure for mechanical and media mixing and atomization, comprising a housing 1, which is the housing of the nozzle and is used to connect various components. An air inlet pipe 3 is fixedly connected to the bottom left of the housing 1 for gas to enter the housing 1. A liquid inlet pipe 4 is fixedly connected to the bottom right of the housing 1 for liquid to enter the housing 1. A spraying assembly 2 is provided on the upper part of the housing 1 for atomizing and spraying the liquid.

[0032] Furthermore, the lower part of the outer casing 1 is provided with a connecting cavity 11 for connecting various components. The upper part of the connecting cavity 11 is frustum-shaped, with its lower diameter larger than its upper diameter. The upper part of the connecting cavity 11 is provided with an atomizing cavity 12 for mixing liquid and gas to facilitate atomization. The lower part of the atomizing cavity 12 is provided with a diffusion trough 121, with its lower diameter smaller than its upper diameter. The upper part of the atomizing cavity 12 is provided with a gathering trough 122, with its lower diameter larger than its upper diameter. The connecting cavity 11 and the atomizing cavity 12 are connected by... The fit between the mounting groove 14 and the gas-liquid mixture allows the fluid to be rapidly atomized through multiple rapid expansions of the flow channel. The top of the atomizing chamber 12 is provided with the mounting groove 14, which is funnel-shaped with a lower diameter smaller than the upper diameter. The middle of the atomizing chamber 12 is fixedly connected with a uniform material plate 13, which is used to further uniformize the gas and liquid to facilitate the mixing of gas and liquid. The middle of the uniform material plate 13 is provided with fine holes. The top of the outer shell 1 is provided with an annular groove 15, which is used to connect the connecting ring 23.

[0033] like Figures 3-4 As shown, the spraying assembly 2 includes a mounting plate 21 for connecting various components. A connecting cone 22 is fixedly connected to the bottom surface of the mounting plate 21 for mounting multiple spiral blades 221. A connecting ring 23 is fixedly connected to the bottom surface of the mounting plate 21 for connecting the spraying assembly 2 to the outer casing 1 and for mounting the spraying assembly 2. The connecting ring 23 is rotatably connected to the annular groove 15 to accommodate the rotation of the mounting plate 21. Multiple spiral blades 221 are fixedly connected to the outside of the connecting cone 22, arranged in a spiral pattern to facilitate the movement of fluid. Multiple spraying chambers 211 are opened in the middle of the mounting plate 21 for atomizing liquid spraying. Multiple spraying chambers 211 are sequentially opened between two adjacent spiral blades 221. Spray nozzles 212 are opened on the side of the multiple spraying chambers 211 that are far apart from each other to assist in atomizing liquid spraying and expand the spraying range.

[0034] Working principle: During use, gas is supplied to the outer casing 1 through the air inlet pipe 3, and liquid is supplied to the outer casing 1 through the liquid inlet pipe 4. The liquid and gas will undergo initial mixing in the connecting chamber 11. When the liquid and gas enter the atomizing chamber 12 through the connecting chamber 11, they will undergo the first rapid expansion, at which point initial atomization can be achieved. With the continuous input of gas and liquid, the mixed fluid will flow towards the uniform material plate 13. When the fluid passes through the multiple holes on the uniform material plate 13, the fluid will be cut into multiple beams. After passing through the uniform material plate 13, the multiple beams of fluid will re-aggregate and mix, thereby completing a more uniform gas-liquid mixture. Then the fluid will be collected in the trough 1. The fluid is gathered and transported into the mounting groove 14. The fluid will expand rapidly twice to achieve atomization. The fluid will flow through the gaps between the multiple spiral blades 221 to the spray chamber 211 and the spray nozzle 212 and be sprayed out, thus completing atomization. When the fluid flows between the multiple spiral blades 221, since the spiral blades 221 are spirally arranged, when the fluid flows, it will push the spiral blades 221. The spiral blades 221 will drive the connecting cone 22 fixed thereto to rotate. The connecting ring 23 will rotate in the ring groove 15. The mounting plate 21 fixed to the connecting cone 22 will be driven to rotate, thereby expanding the spray range of the nozzle.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
