Description

Technical Field

[0001] This utility model relates to the field of high-speed centrifugal rotary atomizer technology, and in particular to the structure of a wind-driven high-speed atomizer wind wheel. Background Technology

[0002] High-speed pneumatic atomizers are widely used in industrial dust removal, agricultural spraying, medical atomization and other fields. They convert the kinetic energy of compressed air into rotational mechanical energy through a pneumatic impeller, which drives the atomizing wheel to rotate at high speed to complete the atomization operation. As the core transmission component, the structural rationality of the pneumatic impeller directly affects the atomizer's operational stability, atomization efficiency and service life.

[0003] Existing high-speed air-powered atomizers have significant technical defects in their fan wheels: due to their compact structure and oil-free lubrication design, insufficient positioning accuracy during installation leads to loosening or misalignment of the connection between the main shaft and the fan wheel. During high-speed rotation, the bearings are subjected to abnormal radial forces, making them prone to wear and seizure; simultaneously, the main shaft is subjected to non-uniform torque, frequently resulting in bending and breakage, severely shortening the equipment's lifespan, increasing maintenance frequency and costs, and hindering the continuous and efficient operation of the atomizer. Therefore, we propose a new structure for the fan wheel of a high-speed air-powered atomizer to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing wind turbines, which have a compact structure but lack oil lubrication and have insufficient positioning accuracy, resulting in loose or eccentric connection between the main shaft and the wind turbine, causing bearing wear, seizure, and breakage, thus shortening the service life, maintenance frequency, and cost. Therefore, this utility model proposes a wind turbine structure for a high-speed wind turbine atomizer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A structure of a wind turbine for a high-speed atomizer includes a reinforcing boss, and a wind turbine blade assembly is integrally formed at the bottom of the reinforcing boss. The wind turbine blade assembly has multiple blades evenly distributed around its circumference and a central positioning hole is formed in the middle. The wind turbine blade assembly has two symmetrical upper weight reduction grooves at the top and a lower weight reduction groove at the bottom. The lower weight-reducing trough contains three counterweight bins evenly distributed circumferentially.

[0006] In one possible design, the top of the reinforcing boss is integrally connected to the small boss, and the reinforcing boss and the small boss are coaxially formed with a through hole, which communicates with the central positioning hole.

[0007] In one possible design, a conical locking cylinder is fixedly connected to the bottom of the wind turbine blade assembly. The inner cavity of the conical locking cylinder is connected to a central positioning hole, and its outer cylindrical surface is provided with external threads and threadedly connected to a locking nut.

[0008] In one possible design, the conical locking cylinder has two symmetrically formed tension grooves, and the inner wall of each tension groove is provided with continuous sinusoidal ripples.

[0009] In one possible design, the upper weight-reducing groove is semi-fan-shaped, and the lower weight-reducing groove is a conical groove.

[0010] In one possible design, each of the counterweight chambers is provided with a counterweight block, and the counterweight block has a sliding groove on both sides. The inner wall of the counterweight chamber is provided with a limiting protrusion that is embedded in the sliding groove. The counterweight block is threadedly connected to two fixing bolts that pass through the counterweight chamber.

[0011] In this application, firstly, the main shaft is inserted into the center positioning hole of the wind turbine, and the thrust locking nut (5) is rotated and moved upward along the thread until it is close to the thrust guide inclined surface. At this time, the tension groove (8) is squeezed to generate radial tension force, and the main shaft is firmly locked in the center positioning hole, so as to realize the reliable connection between the main shaft and the wind turbine. Compressed air acts on the blades of the wind turbine blade assembly (1). The blades are evenly distributed around the circumference, which makes the power distribution uniform and drives the wind turbine to rotate. The upper and lower weight reduction parts reduce the inertia of the wind turbine, reduce energy consumption, and make the rotation more flexible. The power is transmitted to the atomizing wheel through the main shaft, which improves the power transmission efficiency. If a slight imbalance occurs during operation, the counterweight (10) in the counterweight chamber (9) can be replaced. The counterweight (10) is positioned by the limiting protrusion (11) and then locked with the fixing bolt (12) to ensure dynamic balance stability, ensure that the wind turbine rotates continuously, smoothly and at high speed, and maintain the consistency of atomization effect.

[0012] Beneficial effects: In this utility model, the structure of the wind turbine of the high-speed atomizer is significantly reduced by symmetrically opening two upper weight-reduction grooves at the top of the wind turbine blade assembly and a lower weight-reduction groove at the bottom. When driven by compressed air, the starting resistance of the wind turbine is reduced, which can quickly reach the working speed and reduce energy loss. At the same time, the lightweight design reduces the centrifugal force load during high-speed rotation, making the wind turbine run more smoothly, avoiding vibration caused by the center of gravity shift, reducing the impact on the main shaft and bearings, and improving the operational stability of the atomizer. In this invention, the structure of the wind turbine wheel of a high-speed wind-driven atomizer utilizes a thrust guide inclined surface at the lower part of the central positioning hole, which engages with a tension groove to form a thrust locking nut, creating a self-centering tensioning structure. When the nut is threaded upwards and pressed against the inclined surface, the tension groove undergoes elastic deformation, causing the central positioning hole to fit tightly against the main shaft, achieving precise positioning for repeated installations. This structure requires no complex tooling and can be reliably assembled by hand, reducing installation difficulty. Simultaneously, it ensures the coaxiality of the main shaft and the wind turbine wheel, reducing mechanical wear caused by assembly errors. In this utility model, the structure of the wind turbine of the high-speed atomizer is improved by compensating for dynamic imbalance caused by processing errors or wear through three equidistantly distributed counterweight chambers in the lower weight reduction groove and replaceable counterweight blocks located in the counterweight chambers. This not only improves the dynamic balance accuracy of the wind turbine and reduces vibration noise during rotation, but also facilitates balance calibration during later maintenance and extends the fault-free operation time of the equipment. In this invention, the weight is reduced by the upper and lower weight-reducing grooves, which reduces starting resistance and improves the smoothness and stability of operation; the self-centering tensioning structure of the central positioning hole achieves precise positioning, simplifies installation, and ensures coaxiality to reduce mechanical wear; the counterweight chamber and replaceable counterweight compensate for dynamic imbalance, which not only improves dynamic balance accuracy but also extends the trouble-free operation time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figure 1-4 A wind turbine structure includes a reinforcing boss 2, with a wind turbine blade assembly 1 fixedly connected to the bottom of the reinforcing boss 2. The wind turbine blade assembly 1 consists of multiple blades evenly distributed in a circumferential pattern, ensuring uniform power distribution when compressed air acts on the blades, resulting in smoother rotation of the wind turbine. The wind turbine blade assembly 1 has a central positioning hole for inserting the main shaft.

[0017] The impeller blade assembly 1 is equipped with a weight-reduction component, which includes an upper weight-reduction groove 6 and a lower weight-reduction groove 7. The upper weight-reduction groove 6 is located at the top of the impeller blade assembly 1, and consists of two grooves arranged in a semi-fan shape and symmetrically. The lower weight-reduction groove 7 is located at the bottom of the impeller blade assembly 1 and is a conical groove. The design of the upper and lower weight-reduction grooves significantly reduces the weight of the impeller itself. When driven by compressed air, the starting resistance of the impeller is reduced, allowing it to quickly reach its operating speed, reducing energy consumption. Simultaneously, it reduces the centrifugal force load during high-speed rotation, making the impeller run more smoothly, avoiding vibrations caused by center of gravity shift, reducing impact on the main shaft and bearings, and improving the operational stability of the atomizer.

[0018] The bottom of the wind turbine blade assembly 1 is equipped with three counterweight components at equal intervals inside the lower weight reduction groove 7. Each counterweight component includes a counterweight chamber 9, a counterweight block 10, limiting protrusions 11, and fixing bolts 12. The counterweight chamber 9 is fixedly installed on the top inner wall of the lower weight reduction groove 7, and the counterweight block 10 is installed inside the counterweight chamber 9. Multiple limiting protrusions 11 are provided on both sides of the inner wall of the counterweight chamber 9, and the counterweight chamber 9 has sliding grooves corresponding to the multiple limiting protrusions 11, allowing the counterweight chamber 9 to slide in connection with the multiple limiting protrusions 11. Two fixing bolts 12 are threaded through the counterweight chamber 9, and both fixing bolts 12 are threaded through the counterweight block 10. When a slight imbalance occurs during operation, the counterweight 10 in the counterweight chamber 9 can be replaced. The counterweight 10 is positioned by the limiting protrusion 11 and then locked with the fixing bolt 12 to ensure dynamic balance stability, ensure that the wind turbine rotates continuously, smoothly and at high speed, maintain the consistency of atomization effect, improve the dynamic balance accuracy of the wind turbine, reduce vibration noise during rotation, facilitate balance calibration during later maintenance, and extend the fault-free operation time of the equipment.

[0019] This application can be used in the field of high-speed centrifugal rotary atomizer technology, or in other fields applicable to this application.

[0020] In another embodiment: Reference Figure 2-4Based on Embodiment 1, an improvement is made to the structure of the wind turbine wheel of a high-speed wind-driven atomizer, which is applied to the field of high-speed centrifugal rotary atomizer technology. A conical locking cylinder 4 is fixedly installed at the bottom of the wind turbine blade assembly 1, and its inner cavity is connected to the central positioning hole of the wind turbine blade assembly 1. The outer wall of the conical locking cylinder 4 is threaded and threadedly connected to a locking nut 5. Two tension grooves 8 are symmetrically formed on the conical locking cylinder 4, and each tension groove 8 has a sinusoidal wave on its closest side. When the main shaft is inserted into the central positioning hole, the locking nut 5 is rotated and moved upwards along the thread until it is pressed against the thrust guide slope of the conical locking cylinder 4. At this time, the tension grooves 8 are compressed, generating radial tension force, and the main shaft is firmly locked in the central positioning hole, achieving a reliable connection between the main shaft and the wind turbine wheel. This structure forms a self-centering tensioning structure, requiring no complex tooling, allowing for reliable assembly by hand, reducing installation difficulty, and ensuring the coaxiality of the main shaft and the wind turbine wheel, reducing mechanical wear caused by assembly errors.

[0021] The top of the reinforcing boss 2 is fixedly connected to a small boss 3. Both the reinforcing boss 2 and the small boss 3 have through holes that are connected to the center positioning hole of the wind turbine blade assembly 1, which facilitates the through installation of the main shaft and ensures the smooth transmission of power.
