Description

Technical Field

[0001] This utility model relates to the field of surface coating technology, specifically to a multi-stage swirling atomizing nozzle device based on multi-stage atomization control. Background Technology

[0002] In the field of surface coating technology, atomizing nozzles are the core components for achieving uniform spraying of liquid coatings. Atomizing nozzles mainly adopt single methods such as pressure atomization, pneumatic atomization, or rotary atomization.

[0003] In practical use, there are defects. The single-stage atomization structure of the atomizing nozzle has poor adaptability to high viscosity liquids and is prone to producing large droplets with discrete particle size distribution. The droplet scattering rate is high during atomization, especially when spraying at high flow rates. The material utilization rate is low, which increases production costs and environmental pollution risks. In addition, the airflow constraint mechanism of the nozzle is simple and cannot dynamically adjust the atomization angle. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a multi-stage swirling atomizing nozzle device based on multi-stage atomization control, which solves the problems of poor coating uniformity, high material waste rate, and insufficient adaptability to complex curved surfaces in existing spraying equipment.

[0005] To achieve the above objectives, this utility model employs the following technical solution: a multi-stage swirling atomizing nozzle device based on multi-stage atomization control, comprising a primary atomizing chamber, a secondary swirling crushing chamber, and a tertiary laminar flow nozzle. A feed valve is fixedly connected to one side of the primary atomizing chamber, and an air inlet is provided at the bottom of the primary atomizing chamber. The secondary swirling crushing chamber is fixedly installed at the top of the primary atomizing chamber. A first air inlet ring is fixedly fitted at the bottom of the secondary swirling crushing chamber, and a first air inlet valve is fixedly connected to one side of the first air inlet ring. A second air inlet ring is slidably fitted at the top of the secondary swirling crushing chamber, and a second air inlet valve is fixedly installed on one side of the second air inlet ring. A limiting member is fixedly fitted on the surface of the secondary swirling crushing chamber, and the second air inlet ring and the limiting member are slidably inserted into each other. The tertiary laminar flow nozzle is fixedly installed at the top of the secondary swirling crushing chamber, and a discharge port is provided at the top of the tertiary laminar flow nozzle. An air curtain constraint ring is fixedly fitted on the surface of the tertiary laminar flow nozzle, and the air curtain constraint ring is connected to the top of the second air inlet ring.

[0006] The first air intake ring includes a first air supply hood and a tangential air intake channel. The first air supply hood is fixedly sleeved on the bottom of the secondary cyclone crushing chamber, the tangential air intake channel is fixedly installed inside the first air supply hood, and the first air intake valve is fixedly installed on one side of the first air supply hood.

[0007] The tangential air intake channel is arranged tangentially along the secondary cyclone crushing chamber. The tangential air intake channel penetrates the surface of the secondary cyclone crushing chamber to its interior. There are multiple sets of tangential air intake channels, which are arranged in a circular array.

[0008] The second air intake ring includes a second air supply hood, a sealing ring, and a limiting spring. The second air supply hood is slidably sleeved on the top of the secondary cyclone crushing chamber, the sealing ring is fixedly installed on the top of the second air supply hood, and the limiting spring is fixedly installed on the bottom of the second air supply hood.

[0009] The limiting springs are in multiple sets and arranged in a circular array.

[0010] The limiting component includes a fixing ring and a limiting baffle. The fixing ring is fixedly installed on the surface of the secondary cyclone crushing chamber, and the limiting baffle is fixedly installed on the top of the fixing ring.

[0011] The limiting baffles are in multiple sets and arranged in a circular array, with the limiting baffles and limiting springs being staggered.

[0012] The air curtain constraint ring includes a conical ring body and a jet pipe. The conical ring body is fixedly installed on the surface of the three-stage laminar flow nozzle. The jet pipe is located inside the conical ring body, and the top end of the jet pipe is slidably connected to the top end of the conical ring body. The bottom end of the jet pipe passes through the top end of the second air intake ring.

[0013] The number of jet pipes is multiple and arranged in a circular array. Each jet pipe consists of a pipe body and a sphere. The sphere is slidably installed on the top of the conical ring, and the pipe body is fixedly installed on the bottom of the sphere.

[0014] The beneficial effects of this utility model are as follows: This invention delivers high-pressure gas to the first gas conveying hood along the first inlet valve, allowing the gas to enter the secondary cyclone crushing chamber through a tangentially arranged annular inlet channel. This creates a high-speed cyclone field that further crushes the initially broken droplets, reducing their size and transforming the liquid material into ultrafine, uniform droplets, thus improving the coating effect of the equipment. High-pressure gas is then delivered to the second gas conveying hood along the second inlet valve, allowing the gas to travel from the annular jet pipe to the outlet of the tertiary laminar flow nozzle. The resulting laminar flow curtain constrains the droplets, reducing material scattering and optimizing droplet distribution. The droplets ejected from the outlet of the tertiary laminar flow nozzle are precisely projected onto the workpiece surface, forming a uniform protective coating. Rotating the second gas conveying hood causes a limiting spring to contact a limiting baffle until the limiting spring deforms and passes through the limiting baffle, restricting the free rotation of the second gas conveying hood. The rotating second gas conveying hood causes the jet pipe to slide at the top of the conical ring, adjusting the angle of the constrained gas jet. Attached Figure Description

[0017] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 5 The present invention will be further described below.

[0019] A multi-stage swirling atomizing nozzle device based on multi-stage atomization control includes a primary atomizing chamber 1, a secondary swirling crushing chamber 3, and a tertiary laminar flow nozzle 6. A feed valve 2 is fixedly connected to one side of the primary atomizing chamber 1, and an air inlet is provided at the bottom of the primary atomizing chamber 1. The secondary swirling crushing chamber 3 is fixedly installed at the top of the primary atomizing chamber 1, and a first air inlet ring 4 is fixedly fitted at the bottom of the secondary swirling crushing chamber 3. A first air inlet valve 5 is fixedly connected to one side of the first air inlet ring 4. The top of the secondary cyclone crushing chamber 3 is fitted with a second air inlet ring 7. A second air inlet valve 8 is fixedly installed on one side of the second air inlet ring 7. A limiting member 9 is fixedly fitted on the surface of the secondary cyclone crushing chamber 3, and the second air inlet ring 7 and the limiting member 9 are slidably inserted into each other. The third-stage laminar flow nozzle 6 is fixedly installed at the top of the secondary cyclone crushing chamber 3. The top of the third-stage laminar flow nozzle 6 is provided with a discharge port. An air curtain constraint ring 10 is fixedly fitted on the surface of the third-stage laminar flow nozzle 6, and the air curtain constraint ring 10 is connected to the top of the second air inlet ring 7. Specifically, high-pressure gas is supplied to the interior of the primary atomizing chamber 1 through the air inlet to initially break up the liquid. Liquid material is supplied to the interior of the primary atomizing chamber 1 through the feed valve 2. High-pressure gas is supplied to the interior of the secondary cyclone crushing chamber 3 through the first air inlet valve 5 and the first air inlet ring 4 to further break up the liquid. High-pressure gas is supplied to the air curtain constraint ring 10 through the second air inlet valve 8 and the second air inlet ring 7 to constrain the liquid. The second air inlet valve 8 is limited by the limiting member 9, which allows the angle of the constrained airflow to be adjusted by the air curtain constraint ring 10.

[0020] The first air intake ring 4 includes a first air supply hood 401 and a tangential air intake channel 402. The first air supply hood 401 is fixedly sleeved on the bottom of the secondary cyclone crushing chamber 3, the tangential air intake channel 402 is fixedly installed inside the first air supply hood 401, and the first air intake valve 5 is fixedly installed on one side of the first air supply hood 401. Specifically, gas is introduced into the interior of the secondary cyclone crushing chamber 3 through the tangential air intake channel 402 via the first gas supply hood 401, further crushing the droplets in the secondary cyclone crushing chamber 3.

[0021] The tangential air intake channel 402 is arranged tangentially along the secondary cyclone crushing chamber 3. The tangential air intake channel 402 penetrates the surface of the secondary cyclone crushing chamber 3 to its interior. There are multiple sets of tangential air intake channels 402, which are arranged in a circular array. Specifically, by tangentially annularly arranged tangential air intake channels 402, the gas blown into the secondary vortex crushing chamber 3 by multiple sets of tangential air intake channels 402 forms a high-speed vortex air field, which promotes further crushing of droplets.

[0022] The second air intake ring 7 includes a second air conveying hood 701, a sealing ring 702, and a limiting spring 703. The second air conveying hood 701 is slidably sleeved on the top of the secondary cyclone crushing chamber 3. The sealing ring 702 is fixedly installed on the top of the second air conveying hood 701. The top of the second air conveying hood 701 has an opening, which is correspondingly set with the air curtain constraint ring 10. The limiting spring 703 is fixedly installed on the bottom of the second air conveying hood 701. Specifically, gas is delivered to the interior of the jet pipe 1002 through the second gas delivery hood 701. The sealing ring 702 allows the conical ring 1001 to slide to a certain extent inside the jet pipe 1002 as the second gas delivery hood 701 rotates, adjusting the top opening direction of the jet pipe 1002 and preventing gas leakage from the second gas delivery hood 701 into the interior of the conical ring 1001. The rotation of the second gas delivery hood 701 through the opening allows the jet pipe 1002 to slide. The connection between the limiting spring 703 and the limiting member 9 restricts the free rotation of the second air intake ring 7.

[0023] The limiting spring clips 703 are in multiple sets and arranged in a circular array; Specifically, multiple sets of limiting springs 703 are used to enhance the rotation limiting effect of the limiting component 9 on the second intake ring 7.

[0024] The limiting component 9 includes a fixing ring 901 and a limiting baffle 902. The fixing ring 901 is fixedly installed on the surface of the secondary cyclone crushing chamber 3, and the limiting baffle 902 is fixedly installed on the top of the fixing ring 901. Specifically, by interlocking the limiting baffle 902 and the limiting spring 703, the second air supply cover 701 is restricted from sliding freely. The second air supply cover 701 needs to be turned until the limiting spring 703 deforms and passes through the limiting baffle 902, thereby adjusting the rotation angle of the second air supply cover 701.

[0025] The number of limiting baffles 902 is multiple and arranged in a circular array. The limiting baffles 902 and the limiting spring pieces 703 are arranged alternately. Specifically, multiple sets of limiting baffles 902 are used to enhance the rotation limiting effect of the limiting component 9 on the second air intake ring 7.

[0026] The air curtain constraint ring 10 includes a conical ring body 1001 and a jet pipe 1002. The conical ring body 1001 is fixedly installed on the surface of the three-stage laminar flow nozzle 6. The jet pipe 1002 is located inside the conical ring body 1001, and the top end of the jet pipe 1002 is slidably connected to the top end of the conical ring body 1001. The bottom end of the jet pipe 1002 passes through the top end of the second air intake ring 7. The bottom end of the jet pipe 1002 is connected to the sealing ring 702 and passes through the opening of the second air supply hood 701. Specifically, the conical ring 1001 positions the jet pipe 1002 above the second air intake ring 7, and the sliding connection between the two allows the jet pipe 1002 to adjust the angle of its top outlet as the second air supply shroud 701 rotates.

[0027] There are multiple sets of jet pipes 1002 arranged in a circular array. Each jet pipe 1002 consists of a pipe body and a sphere. The sphere is slidably installed on the top of the conical ring 1001, and the pipe body is fixedly installed on the bottom of the sphere. Specifically, the sphere allows for more free adjustment of the angle of the jet pipe 1002. Under the push of the pipe body by the second air supply cover 701 and the sealing of the sealing ring 702, the top of the jet pipe 1002 slides at the conical ring 1001, so that the jet pipe 1002 adjusts its angle with the second air supply cover 701.

[0028] In summary: When in use, the liquid protective material is introduced into the first-stage atomizing chamber 1 through the feed valve 2. It encounters and is initially broken down by the high-pressure gas introduced through the bottom air inlet of the first-stage atomizing chamber 1, forming droplets of 50-100 μm. These droplets then enter the second-stage vortex-breaking chamber 3. A second portion of high-pressure gas is introduced into the first air supply hood 401 through the first air inlet valve 5. The gas then passes through multiple tangentially arranged annular air inlet channels 402 and is input into the second-stage vortex-breaking chamber 3. Under the action of the resulting high-speed vortex air field, the droplet size is further reduced to 10-30 μm. Finally, the droplets reach the third-stage laminar flow nozzle 6 and are ejected. A third portion of high-pressure gas is introduced into the second gas delivery hood 701 through the second air inlet valve 8. The gas is then output to the area around the outlet of the third-stage laminar flow nozzle 6 through multiple inclined jet pipes 1002, forming a laminar flow air curtain to constrain the droplets, reduce material scattering during the coating process, optimize the droplet distribution, and enable the droplets to be accurately projected onto the workpiece surface to form a uniform protective coating. The second gas delivery hood 701 can be rotated as needed, causing the limiting spring 703 to undergo elastic deformation and pass through the surface of the limiting baffle 902. The second gas delivery hood 701 pulls the jet pipes 1002 to slide and adjust the angle of the constrained airflow, thereby achieving adjustable droplet scattering angle.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
