Description

Technical Field

[0001] The present application relates to the technical field of fan rotors, and in particular to a high-efficiency three-element flow main exhaust rotor. Background Art

[0002] Currently, centrifugal fans, as a crucial pneumatic conveying device in modern industrial production, are widely used in a variety of industries, including chemical, metallurgy, and power generation. With the continuous advancement of industrial automation, the performance requirements for centrifugal fans are also becoming increasingly stringent. Especially for large-scale industrial equipment, efficient airflow not only improves production efficiency but also significantly reduces energy consumption and maintenance costs. Therefore, research and development of high-performance centrifugal fan main exhaust rotors is of great significance.

[0003] However, under high-speed operating conditions, the existing main exhaust rotor design is prone to uneven airflow distribution, thereby affecting the overall aerodynamic efficiency. This uneven airflow distribution problem not only reduces the performance of the fan, but also increases energy consumption and maintenance costs, limiting the practicality and reliability of centrifugal fans in high-demand application scenarios.

[0004] In view of the above problems, a high-efficiency three-element flow main pumping rotor is now designed. Utility Model Content

[0007] A wheel disc, wherein a mounting hole is provided at the center of the wheel disc;

[0008] Wheel covers, which are provided in two groups, and the two groups of wheel covers are symmetrically arranged on both sides of the wheel disc;

[0009] The blades are provided in several groups, and the blades are symmetrically arranged on both sides of the wheel disc. The blades are evenly distributed in a ring shape with the axis of the wheel disc as the axis, and the blades are fixedly connected to the wheel disc and the wheel cover.

[0010] In some embodiments, one end of the blade close to the mounting hole is twisted and bent toward the outer arc of the blade, and the angle P between the blade and the wheel disc increases continuously as the distance between the blade and the mounting hole increases.

[0011] In some embodiments, a plurality of surfacing rods are equidistantly provided on both sides of the blade.

[0015] The embodiment of the present application provides a high-efficiency three-flow main extraction rotor. The present application effectively improves the aerodynamic efficiency and stability of the centrifugal fan by optimizing the geometric shape and connection method of the blades, and adding cladding rods, welding layers and high-temperature resistant coatings. The twisted design of the blades reduces eddy currents and turbulence, and improves the uniform distribution of the airflow.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] The embodiment of the present application provides a high-efficiency three-dimensional flow main pumping rotor, which can solve the problem in the related art that the existing main pumping rotor design easily leads to uneven airflow distribution, which affects the overall aerodynamic efficiency.

[0025] See also Figure 1-Figure 4 A high-efficiency three-element flow main extraction rotor comprises a disc 1, a wheel cover 2, and blades 3. A mounting hole 11 is provided in the center of the disc 1. The disc 1 can be made of high-strength alloy steel to ensure its strength and stability under high-speed rotation conditions. The mounting hole 11 is used to connect to the drive shaft to ensure the coaxiality and balance of the entire rotor. The diameter and shape of the mounting hole 11 can be adjusted according to actual needs to accommodate different types of drive shafts.

[0026] The wheel covers 2 are provided in two groups, and the two groups of wheel covers 2 are symmetrically arranged on both sides of the wheel disc 1. The blades 3 are provided in a plurality of groups, and the plurality of blades 3 are symmetrically arranged on both sides of the wheel disc 1. The plurality of blades 3 are evenly distributed in a ring shape with the axis of the wheel disc 1 as the axis. The blades 3 are fixedly connected to the wheel disc 1 and the wheel covers 2. The blades 3 can be made of high-strength aluminum alloy or titanium alloy to improve their fatigue resistance and corrosion resistance.

[0027] In this way, blades 3 and wheel covers 2 are respectively arranged on both sides of the wheel disc 1, and the geometric shape and connection method of the blades 3 can be optimized to make the airflow pass evenly from both ends. While ensuring the uniform distribution of the airflow, the aerodynamic efficiency and stability of the centrifugal fan are effectively improved. In this way, the maintenance of the fan can be reduced and the energy consumption can be reduced. It is easy to use and has strong practicality.

[0028] Specifically, in this embodiment, the end of the blade 3 close to the mounting hole 11 is twisted and bent toward the outer arc of the blade 3, and the angle P between the blade 3 and the wheel disc 1 increases continuously as the distance between the blade 3 and the mounting hole 11 increases;

[0029] according to Figure 3As can be seen from the accompanying drawings, as the different positions A, B, and C of the blade 3 change, the angle P between the blade 3 and the disc 1 is also constantly increasing. This twisted design can effectively guide the airflow, reduce eddy currents and turbulence, and improve aerodynamic efficiency. At the same time, in actual operation, the torsion angle of the blade 3 can be adjusted according to the specific working conditions to achieve the optimal airflow distribution effect, which is highly practical.

[0030] Wherein, a number of surfacing rods 4 are equidistantly provided on both sides of the blade 3;

[0031] In this way, the structural strength of the blade 3 can be enhanced by the cladding rod 4, thereby ensuring the stability of the fan operation and the service life. At the same time, the cladding rod 4 can also protect the surface of the blade 3 to ensure the wear resistance and high temperature resistance of the blade 3, thereby ensuring the service life of the blade 3.

[0032] Furthermore, in this embodiment, the end of the blade 3 away from the mounting hole 11 is sleeved with a welding layer 5;

[0033] In this way, a protective film can be formed on the outer end of the blade 3 to prevent the end of the blade 3 from being worn and corroded, which can further ensure the service life and stability of the blade 3, thereby ensuring the service life of the fan, and having strong practicality.

[0034] Furthermore, both sides of the end of the blade 3 away from the mounting hole 11 are provided with chamfers 31;

[0035] In this way, by setting the chamfer 31 on the blade 3, the contact area between the end of the blade 3 and the welding layer 5 can be increased, so that the welding layer 5 can be more stably connected to the blade 3, thereby preventing the welding layer 5 from falling off the blade 3 and ensuring the stability of the device.

[0036] Preferably, the surface of the blade 3 is provided with a high temperature resistant coating;

[0037] In actual operation, the high-temperature resistant coating can be a nanographene coating, etc., which can further improve the structural strength and high-temperature resistance of the blade 3, thereby ensuring the service life of the fan, reducing the maintenance of the fan, and having strong practicality.
