In actual use, the material feed points of static and dynamic classifiers are concentrated, the material layer is thick, and the internal ventilation effect is poor. Some of the formed material is concentrated inside the material layer and cannot be screened, which easily causes the formed material to return to the roller press to repeat the work, increasing the cyclic load of the roller press, and thus increasing the system power consumption and load. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides an air inlet device adapted to the adjustment of static and dynamic air classifiers, comprising: An air inlet pipe is installed on one side of the bottom of the static air classifier and an air outlet pipe is installed on the top of the dynamic air classifier. One end of the air outlet pipe is connected to an exhaust fan. An air volume regulating plate is installed inside the air inlet pipe. The air volume regulating plate is controlled by an adjusting component installed on the outside of the air inlet pipe. The lower end of the dynamic air classifier is connected to the top of the static air classifier, the top of the static air classifier is connected to a feed pipe, and the bottom of the static air classifier is connected to a flow stabilizing chamber.
[0005] As a preferred embodiment, an air inlet device adapted to the adjustment of static and dynamic air classifiers is provided, wherein there are three air inlet pipes, and the air volume regulating plate is provided in the air inlet pipes located on both sides.
[0006] The solution requires detailed explanation of an air inlet device adapted to the adjustment of static and dynamic air classifiers.

[0008] The solution requires further detailed explanation of an air inlet device adapted to the adjustment of static and dynamic air classifiers, wherein each of the air inlet pipes is arranged at the bottom of the static air classifier in an inclined downward manner.
[0009] Compared with existing technologies, this utility model provides an air inlet device adapted to the adjustment of static and dynamic air classifiers. It includes an air inlet pipe installed on one side of the bottom of the static air classifier and an exhaust pipe installed on the top of the dynamic air classifier. One end of the exhaust pipe is connected to an exhaust fan, and an airflow regulating plate is installed inside the air inlet pipe. The airflow regulating plate is controlled by an adjusting component installed on the outside of the air inlet pipe. The lower end of the dynamic air classifier is connected to the top of the static air classifier. The top of the static air classifier is connected to a feed pipe, and the bottom of the static air classifier is connected to a flow stabilizing chamber. In use, the exhaust fan can be activated to allow natural air to enter the static air classifier through the air inlet pipe, increasing the ventilation volume of the material layer inside the static air classifier and improving its classification efficiency.

Meanwhile, the adjustment component, in conjunction with the air volume adjustment plate, can control the air volume entering the static air classifier, making it suitable for air classification operations under different air volume requirements and highly practical.

[0015] Example 1 An air intake device adapted to the adjustment of static and dynamic air classifiers includes an air intake pipe 2 installed on one side of the bottom of the static air classifier 1 and an exhaust pipe 4 installed on the top of the dynamic air classifier 3. An exhaust fan 5 is connected to one end of the exhaust pipe 4. Activating the exhaust fan 5 draws outside natural air into the static air classifier 1 through the air intake pipe 2, increasing the ventilation volume of the material layer inside the static air classifier 1 and thus improving the air classification efficiency. An air volume regulating plate 6 is installed inside the air intake pipe 2, and the air volume regulating plate 6 is controlled by an adjusting component installed on the outside of the air intake pipe 2.

In use, an operating handle 100 can be fixed to the outer end of the mounting shaft 10. By using the operating handle 100, the mounting shaft 10 can be rotated, thereby driving the airflow regulating plate 6 to rotate, thus adjusting the installation angle of the airflow regulating plate 6 within the air inlet pipe 2, thereby controlling the airflow in the air inlet pipe 2. In this embodiment, the installation method of the mounting shaft 10 and the mounting pipe 9 should be such that the mounting shaft 10 cannot rotate automatically within the mounting pipe 9 when not subjected to external force.

[0019] Based on Example 2, an air inlet device adapted to the adjustment of static and dynamic air classifiers is provided. In order to improve the smoothness of air intake, preferably, each air inlet pipe 2 can be installed at the bottom of the static air classifier 1 in an inclined downward manner.
[0020] This utility model provides an air inlet device adapted to the adjustment of static and dynamic air classifiers.

In use, the exhaust fan 5 can be started to allow natural air from outside to enter the static air classifier 1 through the air inlet pipe 2, increasing the ventilation volume of the material layer inside the static air classifier 1 and improving the air classification efficiency. Materials that have reached the forming standard do not need to enter the roller press and can be directly screened by the dynamic air classifier 3, reducing the load on the roller press, reducing segregation in the flow stabilizing chamber 8, reducing system power consumption, and increasing output. Meanwhile, the adjustment component, in conjunction with the air volume adjustment plate 6, can control the air volume entering the static air classifier 1, making it suitable for air classifier operations under different air volume requirements and highly practical.
