Abstract
Description
Technical Field
[0001] This utility model relates to an airflow classification mechanism for the production of spherical graphite, belonging to the field of spherical graphite processing equipment. Background Technology
[0002] In the processing of spherical graphite, the raw materials need to be crushed. To obtain ultrafine powder, the material is further separated after crushing to finally obtain particle sizes that meet the requirements. The separation equipment includes an air classifier, which is a type of sieve that separates coarse and fine particles.
[0003] Grading equipment separates materials based on their weight, achieving the effect of material screening.
[0004] The existing air classifiers used for spherical graphite production have a feed hopper installed at the inlet. To prevent graphite from clumping during transport, an electric stirring mechanism is installed inside the feed hopper. The stirring frame is driven by a motor to rotate, which can break up the graphite clumps during the graphite material transport process. However, the continuous operation of the motor increases the production cost of spherical graphite.
[0005] In summary, this utility model provides an airflow classification mechanism for the production of spherical graphite to solve the above-mentioned problems. Utility Model Content
[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an airflow classification mechanism for the production of spherical graphite, thereby solving the problem mentioned in the background art that the material needs to be dispersed by an electric mixer in advance during the airflow classification process, which increases the production cost of spherical graphite.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an airflow classification mechanism for producing spherical graphite, comprising a classifier body, an air outlet pipe, and an air inlet pipe. The air outlet pipe is connected to the top of the classifier body, and an mounting plate is fixedly fitted on the top of the classifier body. The air inlet pipe is connected to the top of one side of the classifier body and is located below the mounting plate. A feeding hopper passes through the top of the mounting plate on the side away from the air inlet pipe. A feeding pipe is connected to the bottom of the feeding hopper. One end of the feeding pipe extends to the other side of the classifier body. An airflow-driven stirring mechanism passes through the top of the feeding hopper, and an inlet pipe is connected to one side of the top of the feeding hopper.
[0008] Furthermore, the feeding pipe is bent and rotated, the feeding pipe is connected to the classifier body, a solenoid valve is installed on the feeding pipe, and the feeding barrel is fixedly connected to the mounting plate.
[0009] Furthermore, the airflow-driven stirring mechanism includes a fixed box, which is fixedly installed on the top of the feeding hopper. One side of the fixed box is connected to a branch pipe, one end of which passes through the top of the mounting plate and extends to the top of the air inlet pipe. The top of the inner wall of the fixed box is rotatably connected to a stirring shaft via a bearing. One end of the stirring shaft passes through the fixed box and the feeding hopper in sequence and extends to the lower part of the feeding hopper. Six fan blades are evenly fixedly connected to the axial surface of the stirring shaft and inside the fixed box. Connecting frames are fixedly installed on both sides of the stirring shaft and inside the feeding hopper. Multiple stirring rods are evenly fixedly connected from top to bottom between the two connecting frames and the opposite side of the stirring shaft.
[0010] Furthermore, an exhaust vent is provided on the other side of the fixed box, and the stirring shaft is rotatably connected to the feeding bucket via a bearing.
[0011] Furthermore, both ends of the connecting frame are bent, and the bottom of the connecting frame is parallel to the bottom of the inner wall of the feeding hopper.
[0012] Furthermore, the branch pipe is connected to the air inlet pipe, and the stirring rod is installed at an angle.
[0013] The beneficial effects of this utility model are:
[0014] By starting an external air pump, airflow is delivered to the classifier body through the air inlet pipe for the classification and separation of graphite dust particles. At the same time, part of the airflow can be delivered to the fixed box through the branch pipe inside the airflow-driven stirring mechanism. The airflow can drive the fan blades to move and drive the stirring shaft to rotate. The stirring shaft can drive the connecting frame and stirring rod to rotate inside the feeding bucket. This allows the airflow classifier to drive the stirring mechanism to rotate synchronously when delivering airflow for material classification, eliminating the need for a separate motor drive and effectively saving the production cost of spherical graphite.
[0015] Furthermore, by rapidly breaking up agglomerated spherical graphite materials through the rotation of the stirring rod and connecting frame, the effective separation amount of spherical graphite materials can be increased, avoiding secondary and repeated grading processing, thereby effectively improving the processing efficiency of spherical graphite.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Please see Figure 1-5 This utility model provides a technical solution: an airflow classification mechanism for producing spherical graphite, comprising a classifier body 1, an outlet pipe 2, and an inlet pipe 3. The outlet pipe 2 is connected to the top of the classifier body 1, and an mounting plate 4 is fixedly fitted on the top of the classifier body 1. The inlet pipe 3 is connected to the top of one side of the classifier body 1 and is located below the mounting plate 4. The inlet pipe 3 is connected to an external air pump. After the inlet pipe 3 delivers airflow into the interior of the classifier body 1, it generates an airflow vortex. Using centrifugal force, large particles of graphite dust in the air are thrown onto the inner wall of the classifier body 1, while small dust particles are carried away by the outlet pipe. 2. The airflow can be used to classify and separate spherical graphite dust particles. The top of the mounting plate 4 is connected to the side away from the air inlet pipe 3. The bottom of the feeding barrel 5 is connected to the feeding pipe 7. One end of the feeding pipe 7 extends to the other side of the classifier body 1. The top of the feeding barrel 5 is connected to the airflow-driven stirring mechanism 8. The top of the feeding barrel 5 is connected to the feed pipe 6. The feeding pipe 7 is bent and rotated. The feeding pipe 7 is connected to the classifier body 1. A solenoid valve is installed on the feeding pipe 7. The solenoid valve is connected to an external power supply and is equipped with a power control switch. The feeding barrel 5 is fixedly connected to the mounting plate 4.
[0025] Please see Figure 2-5The airflow-driven stirring mechanism 8 includes a fixed box 81, which is fixedly installed on the top of the feeding hopper 5. One side of the fixed box 81 is connected to a branch pipe 82. One end of the branch pipe 82 passes through the top of the mounting plate 4 and extends to the top of the air inlet pipe 3. The top of the inner wall of the fixed box 81 is rotatably connected to a stirring shaft 83 via a bearing. One end of the stirring shaft 83 passes through the fixed box 81 and the feeding hopper 5 in sequence and extends to the lower part of the feeding hopper 5. Six fan blades 84 are evenly fixedly connected to the shaft surface of the stirring shaft 83 and inside the fixed box 81. Connecting frames 86 are fixedly installed on both sides of the stirring shaft 83 and inside the feeding hopper 5. Multiple stirring rods 87 are evenly fixedly connected from top to bottom between the two connecting frames 86 and the opposite side of the stirring shaft 83.
[0026] Please see Figure 2-5 On the other side of the fixed box 81, there is an exhaust hole 85. The stirring shaft 83 is rotatably connected to the feeding barrel 5 through the bearing. The air inside the fixed box 81 can be discharged through the exhaust hole 85. Both ends of the connecting frame 86 are bent, and the bottom of the connecting frame 86 is parallel to the bottom of the inner wall of the feeding barrel 5. The branch pipe 82 is connected to the air inlet pipe 3. The stirring rod 87 is installed at an angle. When the stirring shaft 83 rotates, it can drive the two connecting frames 86 and multiple stirring rods 87 to rotate inside the feeding barrel 5, which can break up the lumpy spherical graphite material inside the feeding barrel 5.
[0027] Detailed implementation: Spherical graphite powder is conveyed to the inside of the feeding hopper 5 through the feeding pipe 6. The material inside the feeding hopper 5 can be conveyed to the inside of the classifier body 1 through the feeding pipe 7. At the same time, the external air pump is started, and the airflow is conveyed to the inside of the classifier body 1 through the air inlet pipe 3 for graphite dust particle classification and separation. At the same time, part of the airflow can be conveyed to the inside of the fixed box 81 through the branch pipe 82 inside the airflow transmission stirring mechanism 8. The airflow can drive the fan blade 84 to move, which in turn can drive the stirring shaft 83 to rotate. Excess air can be discharged from the exhaust hole 85. The stirring shaft 83 can drive the connecting frame 86 and the stirring rod 87 to rotate inside the feeding hopper 5, which can quickly break up the spherical graphite material clumps and convey them to the inside of the classifier body 1 through the feeding pipe 7 for classification and separation. When the airflow classifier conveys airflow to classify materials, it can synchronously drive the stirring mechanism to rotate, without the need for a separate motor drive, which effectively saves the production cost of spherical graphite.
[0028] Furthermore, by rapidly breaking up the agglomerates of spherical graphite material through the rotation of the stirring rod 87 and the connecting frame 86, the effective separation amount of spherical graphite material can be increased, avoiding secondary and repeated grading processing, thereby effectively improving the processing efficiency of spherical graphite.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
