[0024] 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.

[0025] Please see Figure 1-5This utility model provides an embodiment of an air classifier for an air classification system, comprising an air classifier housing 1, an inlet 2 and an outlet 3 installed on the top of the air classifier housing, an inlet 4 and an outlet 5 installed on the bottom of the air classifier housing, air shut-off devices 6 installed on the air classifier housing corresponding to the inlet and outlet positions, a material discharge channel installed inside the air classifier housing, the material discharge channel being connected to the inlet, outlet, air inlet, and outlet, a maintenance mechanism installed on the air classifier housing corresponding to the material discharge channel position, the maintenance mechanism including a maintenance door assembly 7 installed on the outer wall of the air classifier housing, and a transparent viewing window 8 installed on the air classifier housing on the other side opposite to the maintenance door assembly. The above structural design can solve the problem that the original air classifier housing lacked a maintenance mechanism, and when internal material blockage occurred, the upper and lower external connecting equipment had to be removed to clear the internal blockage, resulting in wasted manpower and time and seriously affecting production efficiency. The air inlet is installed on one side of the air classifier box, and a uniform air distribution plate 9 is installed at the air inlet. The uniform air distribution plate is evenly distributed with uniform air distribution holes 10. In the design of the air classifier for the air classification system, the air inlet is installed on one side of the air classifier box, and a uniform air distribution plate is installed at the air inlet. The uniform air distribution plate is evenly distributed with uniform air distribution holes. This preferred solution brings the following beneficial effects: (1) Improved airflow uniformity: The uniform air distribution plate and the uniform air distribution holes on it can effectively distribute the airflow entering the air classifier box evenly, avoiding the formation of vortices or local high-speed zones in the airflow at the air inlet, thereby ensuring the stability and uniformity of the airflow during the air classification process. This is crucial for improving the efficiency and accuracy of air classification. (2) Enhanced air classification effect: The uniform airflow distribution helps the material to achieve more accurate grading and screening in the air classifier box. Materials of different particle sizes or densities can be separated more clearly under the action of uniform airflow, reducing the mixing phenomenon and improving the purity and quality of the product. (3) Reduce equipment wear: Uneven airflow can cause impact and wear on the inner wall or components of the air classifier. The design of the air distribution plate can mitigate this impact, reduce equipment wear, and extend the service life of the equipment. (4) Improve equipment stability: Stable airflow distribution helps maintain the overall smooth operation of the air classifier, reduces vibration and noise caused by airflow fluctuations, and improves the stability and reliability of the equipment. (5) Optimize energy consumption: By optimizing the distribution and flow path of airflow, the air distribution plate design helps reduce energy consumption in the air classification process. Uniform airflow can utilize wind energy more effectively, reduce unnecessary energy loss, and improve energy utilization efficiency.

[0026] The air classifier 1 has a left baffle 11 and a right baffle 12 installed opposite each other. The left and right baffles form a material drop channel 13 between the air classifier and the air classifier. The air classifier has a first baffle 14 installed between the inlet and outlet, and a second baffle 15 installed between the inlet and outlet. The left and right baffles are multi-folded plates, and the material drop channel is wavy. The above structural design has the following advantages: (1) Improved material dispersion: The wavy material drop channel design allows the material to undergo multiple changes in direction and speed during the falling process, thereby increasing the dispersion between material particles. This dispersion helps the material to be exposed to the airflow more evenly, improving the air classification effect. (2) Enhanced contact between airflow and material: The wavy material drop channel not only changes the trajectory of the material, but also makes the airflow form more eddies and turbulent areas in the channel. These areas enhance the contact area and contact time between the airflow and the material, which helps to make fuller use of the airflow force to classify and screen the material. (3) Optimized material classification: The setting of the first and second baffles further refines the flow path of airflow and material. They can guide the airflow in a specific direction while controlling the falling speed and position of the material. This optimization allows materials of different particle sizes or densities to be separated more accurately to different outlets, improving the classification accuracy of the product. (4) Reduced risk of blockage: The wave-shaped material discharge channel design helps to reduce the accumulation and blockage of materials in the channel. As the material constantly changes direction and speed in the channel, its fluidity is enhanced, making it less likely to form dead zones or accumulation points. This reduces the risk of equipment shutdown due to blockage and improves the operational stability and reliability of the equipment. (5) Enhanced equipment adaptability: This optimized scheme allows the air classifier to adapt more flexibly to different types and properties of materials. By adjusting the parameters of the baffles and material discharge channel, accurate classification and screening of materials of different particle sizes, densities and shapes can be achieved, improving the adaptability and flexibility of the equipment.

[0027] The maintenance door assembly includes a door frame 16 and a maintenance door 17 installed on the air classifier. One end of the maintenance door is hinged to the door frame, and the other end of the maintenance door is equipped with a door clamping device. An inspection hole 18 is provided on the air classifier corresponding to the door frame position. A closed sealing protrusion 19 is installed on the outer wall of the air classifier corresponding to the inspection hole position, and the closed sealing protrusion 19 seals with the inner wall of the maintenance door. The door clamping device includes a clamping arm 20 hinged to the air classifier. A clamping handle 21 is installed on one end of the clamping arm, and a clamping plate 22 is installed on the other end of the clamping arm corresponding to the maintenance door position. Multiple door clamping devices are installed side by side. The above structural design has the following advantages: (1) The design of the maintenance door assembly allows maintenance personnel to easily open and close the maintenance door without using complicated tools. The combination of hinged installation and door clamping device ensures the tightness and stability of the maintenance door when closed, while facilitating quick opening for internal inspection and cleaning. (2) This design greatly improves the convenience and efficiency of maintenance; the closed-loop sealing protrusion strip and the sealing design of the inner wall of the maintenance door effectively prevent airflow and dust inside the air classifier from leaking into the external environment. This not only maintains the stability and efficiency of the air classification process, but also reduces environmental pollution and health risks to maintenance personnel. (3) Multiple door clamping devices are installed side by side to ensure that the maintenance door can be evenly stressed when closed, which enhances the sealing effect and improves the safety of the maintenance door. Even in high wind speed or vibration environments, the maintenance door can remain stable and not fall off, ensuring the safety of equipment and personnel.

[0028] Multiple transparent viewing windows (8) are staggered along the material discharge direction, allowing maintenance personnel to comprehensively observe the interior of the air classifier, particularly the material discharge channel and the operational status of key components. This optimized monitoring helps to promptly identify potential problems and take remedial measures, improving equipment reliability and maintenance efficiency. By adjusting the number and position of the transparent viewing windows, as well as the design parameters of the inspection door assembly and door clamping device, this optimized solution allows the air classifier to more flexibly adapt to the needs of different working environments and material characteristics. This adaptability enhances the equipment's versatility and market competitiveness.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
