Description

Technical Field

[0001] This utility model relates to the field of fan rotor technology, and in particular to a coking circulating fan rotor. Background Technology

[0002] Coking circulating fans are an indispensable piece of equipment in modern industrial production, widely used in industries such as steel and chemicals. These fans are primarily used to circulate and transport high-temperature gases to maintain the normal operation of production systems. With the continuous advancement of industrial technology, the performance requirements for coking circulating fans are constantly increasing, especially in terms of improving energy efficiency, reducing noise, and extending service life. Therefore, designing more optimized fan rotor structures has become a current research focus.

[0003] Currently, common methods for achieving efficient gas circulation include, but are not limited to, the following: first, improving airflow efficiency by modifying the rotor blade shape; second, reducing airflow resistance by adjusting the distance between rotor blades; and third, improving airflow distribution by adding guide devices. While these methods can improve fan performance to some extent, existing coking circulating fan rotors, due to structural limitations, still exhibit some airflow turbulence. This turbulence affects airflow efficiency and generates significant noise. These issues not only impact the fan's performance but also limit its promotion and application in demanding scenarios.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A coking circulating fan rotor includes: an assembly plate 1, an air inlet plate 2, a guide plate 3, and a flow divider plate 4. Both the assembly plate 1 and the air inlet plate 2 are circular plates. The assembly plate 1 and the air inlet plate 2 are spaced apart. An air inlet hole 21 is provided on the air inlet plate 2. A guide protrusion 12 is also provided on the assembly plate 1. The guide protrusion 12 protrudes from the assembly plate 1 toward the air inlet hole 21. An assembly hole 11 is provided at the top of the guide protrusion 12. The assembly hole 11 matches other components of the coking circulating fan, allowing it to be assembled with other components. The axis of the assembly hole 11 coincides with the axis of the air inlet hole 21. A guide curved surface 121 is also provided on the guide protrusion 12. The guide curved surface 121 surrounds the assembly hole 11. An assembly inclined surface 13 is also provided on the assembly plate 1. The assembly inclined surface 13 is located on the side of the assembly plate 1 away from the air inlet plate 2. The mounting ramp 13 slopes from the mounting plate 1 toward the air intake plate 2. This increases the thickness of the mounting plate 1 in a specific area, thereby enhancing the structural strength of the mounting plate 1 to a certain extent.

[0020] A deflector plate 3 is disposed between the assembly plate 1 and the air intake plate 2. One side of the deflector plate 3 is fixedly connected to the assembly plate 1, and the other side is fixedly connected to the air intake plate 2. The deflector plate 3 is perpendicular to the assembly plate 1. The included angle α between the deflector plate 3 and the air intake plate 2 is less than 90°. Simultaneously, the deflector plate 3 is curved. An included angle is formed between the deflector plate 3 and the air intake plate 2 radially. One end of the deflector plate 3 corresponds to the projection of the air intake hole 21 onto the assembly plate 1. A deflector ramp 31 is also provided at one end of the deflector plate 3. The included angle β between the deflector ramp 31 and the vertical direction is less than 45°. Furthermore, there are multiple deflector plates 3. The deflector plates 3 are evenly arranged along the circumference of the air intake hole 21. Adjacent deflector plates 3 are spaced apart to form an air duct for airflow. The air inlet 21, the guide surface 121, and the air duct are matched with each other so that the airflow can flow through the air inlet 21, the guide surface 121, and the air duct in sequence.

[0021] The diffuser plate 4 is disposed within the air duct. One side of the diffuser plate 4 is fixedly connected to the mounting plate 1, and the other side is fixedly connected to the air intake plate 2. The diffuser plate 4 is curved. An angle is formed between the diffuser plate 4 and the air intake plate 2 in the radial direction. The diffuser plate 4 is disposed within the air duct. A gap is provided between the end of the diffuser plate 4 and the projection of the air intake hole 21 on the mounting plate 1.

[0022] In practice, this invention is assembled through the assembly hole 11. After assembly, the assembly hole 11 is sealed. In actual use, the entire invention is rotated by a motor or other power equipment. Upon rotation, airflow enters the space between the assembly plate 1 and the intake plate 2 through the air inlet 21. Once inside, guided by the guide surface 121, the airflow begins to contact one end of the guide plate 3 with the guide slope 31. Thus, under the combined action of the guide surface 121 and the guide slope 31, the airflow begins to enter the duct. After entering the duct, the airflow flows under the guidance of the guide plates 3 on both sides. After flowing a certain distance, the airflow contacts the split plate 4, thus being divided into two airflows under the action of the split plate 4. As the airflow continues to flow, it eventually exits the device through the other end of the guide plate 3.

[0023] In summary, this utility model effectively guides airflow through the air inlet 21, the guide surface 121, and the guide slope 31. After the airflow enters the duct, it is further guided by the assembly relationship between the guide plate 3, the assembly plate 1, and the air inlet plate 2. After the airflow has traveled a certain distance, it is divided by the flow divider 4, and guided further by the cooperation of the flow divider 4 and the guide plate 3. Therefore, through the structural design of this utility model, airflow turbulence can be effectively reduced, thereby effectively improving airflow efficiency and reducing operating noise.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
