Description

Technical Field

[0001] This utility model relates to the field of blast furnace equipment technology, and in particular to an airflow uniform distribution device for the air inlet filter of a blast furnace blower. Background Technology

[0002] Blast furnace ironmaking is the core link in modern steel production, and the blast furnace blower is one of the key pieces of equipment in blast furnace production. In the actual operation of the blast furnace blower, uneven airflow distribution is a common problem.

[0003] Some traditional airflow guiding devices have a fixed structure and cannot be adjusted in real time according to actual airflow changes, making it difficult to maintain the best airflow uniformity. In addition, traditional devices can usually only guide the direction of airflow and are not precise enough in controlling the uniform distribution of airflow velocity, resulting in problems such as uneven local temperature and unstable combustion in the blast furnace. In order to solve the above problems, this utility model provides an airflow uniformity device for the blast furnace blower inlet filter. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a blast furnace blower inlet air filter airflow uniform distribution device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A blast furnace blower inlet air filter airflow uniform distribution device includes a mounting frame. Three transmission rods are rotatably connected inside the mounting frame via bearings. Guide plates are fixedly connected to the upper and lower ends of each of the three transmission rods. A transmission assembly is fixedly connected to one side of the mounting frame. An air inlet frame is fixedly connected to the front of the mounting frame. A slot is provided at the upper end of the air inlet frame, and a filter plate is inserted into the slot. A filter screen is installed inside the filter plate. A diameter-changing channel is fixedly connected to the back of the mounting frame.

[0006] As a further improvement of this utility model, the transmission assembly includes a mounting shell fixedly connected to one side of the mounting frame, and a drive rod is rotatably connected inside the mounting shell via a bearing. Three drive bevel gears are evenly arranged on the surface of the drive rod.

[0007] As a further improvement of this utility model, three driven bevel gears are evenly arranged on one side of the mounting frame. The three driven bevel gears are respectively connected to three transmission rods, and the three driven bevel gears respectively mesh with three driving bevel gears.

[0008] As a further improvement of this utility model, a mounting plate is fixedly connected to the upper end of the mounting frame, and a servo motor is fixedly connected to the upper end of the mounting plate. The power end of the servo motor is connected to the drive rod.

[0009] As a further improvement of this utility model, a handle is fixedly connected to the upper end of the filter plate, and sliding grooves adapted to the filter plate are opened on both sides inside the air intake frame.

[0010] As a further improvement of this utility model, the surface of the guide plate is provided with several guide grooves.

[0011] The beneficial effects of this utility model are: By setting up a transmission component, when in use, the servo motor drives the bevel gear set, which drives all the guide plates to rotate synchronously. The angle can be flexibly adjusted according to the actual working conditions, realizing active and precise control of airflow distribution. The guide grooves on the surface of the guide plates further enhance the airflow segmentation and guidance effect, effectively sorting the turbulent airflow entering the device into a uniform flow field. This active flow equalization method significantly improves the uniformity of airflow distribution, provides stable and smooth air intake conditions for the blower, and ensures the stable operation of the blast furnace system.

[0012] By installing a filter plate, the airflow is filtered first through the filter plate during use, avoiding the problem of excessive local load on the subsequent main filter. The plug-in design of the filter plate is installed through a sliding groove and slot, and can be easily disassembled and maintained with the help of a handle, simplifying the replacement process of filter components, extending the service life of the main filter, and reducing system maintenance costs and time.

[0017] 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.

[0018] Reference Figures 1-3 A blast furnace blower inlet air filter airflow uniform distribution device includes a mounting frame 1. Inside the mounting frame 1, three transmission rods 2 are rotatably connected via bearings. The upper and lower ends of the three transmission rods 2 are fixedly connected to guide plates 3. A transmission assembly is fixedly connected to one side of the mounting frame 1. An air inlet frame 4 is fixedly connected to the front of the mounting frame 1. A slot 5 is opened at the upper end of the air inlet frame 4. A filter plate 6 is inserted into the slot 5. A filter screen 7 is set inside the filter plate 6. A variable diameter channel 8 is fixedly connected to the back of the mounting frame 1.

[0019] In this utility model, the transmission assembly includes a mounting shell 9 fixedly connected to one side of the mounting frame 1. The mounting shell 9 can provide reliable protection for the internal parts and prevent external factors from damaging the transmission assembly. Inside the mounting shell 9, a drive rod 10 is rotatably connected via bearings. Three drive bevel gears 11 are evenly arranged on the surface of the drive rod 10. Three driven bevel gears 12 are evenly arranged on one side of the mounting frame 1. The three driven bevel gears 12 are respectively connected to three transmission rods 2 and mesh with the three drive bevel gears 11. Through this meshing transmission method, the power is transmitted from the drive rod 10 to the transmission rod 2, enabling the transmission rod 2 to rotate according to predetermined requirements.

[0020] Mounting plate 13 is fixedly connected to the upper end of mounting frame 1, and servo motor 14 is fixedly connected to the upper end of mounting plate 13. The power end of servo motor 14 is connected to active rod 10. Servo motor 14 can precisely control the speed and direction of active rod 10 according to actual needs, thereby achieving precise adjustment of the angle of guide plate 3.

[0021] A handle 15 is fixedly connected to the upper end of the filter plate 6, allowing operators to easily pull the filter plate 6 by holding the handle 15 for installation, disassembly, and replacement. Slide grooves 16, adapted to the filter plate 6, are provided on both sides of the air intake frame 4. The slide grooves 16 fit tightly with the filter plate 6, ensuring smooth insertion and removal of the filter plate 6, while also providing good positioning to prevent the filter plate 6 from shaking after installation. Several guide grooves 17 are provided on the surface of the guide plate 3. These guide grooves 17 effectively guide and divert the airflow, making the airflow more evenly distributed as it passes through the guide plate 3, thus improving the airflow uniformity.

[0022] In use, external air first enters through the air intake frame 4 and flows through the filter plate 6 inserted into the slot 5. The filter screen 7 inside the filter plate 6 performs preliminary filtration of the air. Then, the airflow enters the mounting frame 1. The operator can start the servo motor 14, which drives the drive rod 10 to rotate. The three drive bevel gears 11 on the drive rod 10 mesh with the three driven bevel gears 12, thereby driving the three transmission rods 2 to rotate synchronously. The rotation of the transmission rods 2 changes the angle of the guide plates 3 fixed at its upper and lower ends. By adjusting the windward angle of the guide plates 3, the airflow can be adjusted. At the same time, the guide grooves 17 on the surface of the guide plates 3 can further divide and guide the airflow, making it evenly distributed. Finally, the airflow after being evenly distributed and adjusted is smoothly output to the blower through the variable diameter channel 8 on the back of the mounting frame 1. When maintenance is required, the filter plate 6 can be pulled out from the slot 5 and the slide groove 16 through the handle 15 for cleaning or replacement.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
