The air blowing fan blows the material and moves it along the conveyor belt, while the air suction fan absorbs the material that has moved above the connecting pipe and collects it into the collection box. This method can accelerate the movement speed of the material with the assistance of airflow. Unqualified coarse material will be guided back to the crushing area by the diversion hood to continue crushing until the required particle size is reached. This enhances the material circulation and precise guiding effect, greatly improves the crushing efficiency, and shortens the crushing time. The collection components can directly collect qualified material after crushing, reducing the time for separate material collection and further improving the working efficiency of the device.

[0023] 2. Through the screening mechanism, the conical filter cartridge blocks the unqualified materials at the top and lifts them through the return pipe to the crusher. This allows the unqualified materials to be quickly transported back for crushing, thus ensuring that all materials are thoroughly crushed and improving the working quality of the device.

[0031] Example 1

[0032] like Figures 1-3 As shown, the present invention proposes a rapid return type diversion hood for an ultrafine pulverizer, comprising a diversion hood body 1, a guide hood 2 disposed outside the diversion hood body 1, a diversion mechanism, a screening mechanism, and a conical filter cylinder 504. The guide hood 2 is used to introduce the pulverized material, allowing the pulverized material to enter the diversion hood.

[0033] The screening mechanism is located inside the diversion hood body 1 and is used to guide unqualified crushed materials back into the crusher.

[0034] The diversion mechanism is located at the bottom of the screening mechanism and inside the diversion hood body 1, and is used to generate airflow in two directions to transport and collect materials.

[0035] The conical filter cylinder 504 is located inside the screening mechanism. The conical filter cylinder 504 is cone-shaped with the tip pointing upwards. The filter holes on the conical filter cylinder 504 are used to pass through the crushed qualified materials. The crushed unqualified materials slide down through the conical surface of the filter cylinder into the screening mechanism and flow back to the crusher.

[0036] The collection assembly includes a sealing ring 301, a pull ring 302, and a collection box 303. The collection box 303 is slidably disposed at the bottom of the diversion mechanism, the sealing ring 301 is disposed on the side of the collection box 303, and the pull ring 302 is disposed on the side of the sealing ring 301 away from the collection box 303.

A connecting block 505 is located on the outside of the connecting pipe 501, and the return pipe 502 is located on the side of the connecting block 505. Four connecting blocks 505 are arranged in a ring around the connecting pipe 501. The end of the return pipe 502 away from the connecting pipe 501 is connected to the crusher. The material is transported into the connecting pipe 501 through the diversion mechanism. The conical filter cylinder 504 blocks the unqualified crushed material on the outside of the conical filter cylinder 504. The material flows along the conical filter cylinder 504 into the return pipe 502 and is then transported back into the crusher through the return pipe 502.

[0038] Example 2

[0039] like Figures 4-6 As shown, this utility model proposes a rapid return type diversion hood for an ultrafine pulverizer. Compared with Embodiment 1, this embodiment details the structure of the diversion mechanism.

[0040] The diversion mechanism includes a coaxial reversing component and a diversion component. The diversion component is located inside the diversion hood body 1 and is used to transport the crushed material and absorb the qualified crushed material into the collection component. The coaxial reversing component is located inside the diversion component and is used to drive the diversion component to simultaneously perform air intake and exhaust. The coaxial reversing component includes a diversion pipe 405, a fixing frame 401, a motor 402, and a rotating shaft 410. The diversion pipe 405 is located inside the diversion hood body 1, the fixing frame 401 is located at the top of the diversion pipe 405, the motor 402 is located inside the fixing frame 401, and the rotating shaft 410 is located at the output end of the motor 402. A gear ring 411 is located on the outer side of the rotating shaft 410, and a spur gear 412 meshes with the inner side of the gear ring 411. A connecting plate 413 is rotatably mounted on the side of the spur gear 412 away from the gear ring 411, and a connecting plate 413 is mounted on the end of the connecting plate 413 away from the spur gear 412. There is a fixed shaft 414. A second spur gear 415 meshes with the side of a first spur gear 412. A second connecting plate 416 is rotatably mounted on the top of the second spur gear 415. A fixed shaft 417 is mounted on the end of the second connecting plate 416 away from the second spur gear 415. A second gear ring 418 meshes with the side of the second spur gear 415 away from the first spur gear 412. A second rotating shaft 419 is mounted at the center of the second gear ring 418. An arc-shaped slide rail 420 is slidably mounted on the outer side of the second gear ring 418. A fixed rod 421 is mounted on the side of the arc-shaped slide rail 420 away from the second gear ring 418. A connecting ring 403 is mounted on the top of the fixed rod 421. The diversion assembly includes an air blower 408, an air intake fan 422, a connecting frame 404, and a rotating tube 407. The air intake fan 422 is located at the end of the rotating shaft 419 away from the gear ring 418. The connecting frame 404 is located at the end of the rotating shaft 410 away from the gear ring 411. The rotating tube 407 is located at the end of the connecting frame 404 away from the rotating shaft 410. The air blower 408 is located on the outside of the rotating tube 407. The circular slide rail 409 is located on the top of the rotating tube 407. A connecting rod 406 is located on the outside of the diversion hood body 1.

[0041] In summary, when using this utility model, the return pipe 502 is connected to the feed inlet of the ultrafine pulverizer. After the ultrafine pulverizer pulverizes the material, it is transported through the guide hood 2 to the inside of the diversion hood. The motor 402 is started, which drives the rotating shaft 410 to rotate. The rotating shaft 410 drives the gear ring 411 to rotate. The gear ring 411 drives the spur gear 412 to rotate on the connecting plate 413. The spur gear 412 drives the spur gear 415 to rotate on the connecting plate 416. The spur gear 415 drives the gear ring 418 to rotate in the opposite direction around the rotating shaft 410 on the arc-shaped slide rail 420. This causes the rotating shaft 410 and the rotating shaft 419 to rotate coaxially and in opposite directions. The rotating shaft 419 drives the suction fan 422 to rotate, thereby drawing the material transported into the connecting pipe 501 downwards. Under suction, the material adheres to the conical filter cartridge 504. Qualified material passes through the conical filter cartridge 504 and enters the diversion pipe 405. Unqualified material is blocked on the outside of the conical filter cartridge 504 and flows along the conical filter cartridge 504 into the return pipe 502, and then is transported back into the crusher through the return pipe 502. The rotating shaft 410 drives the rotating tube 407 to rotate on the circular slide rail 409 through the connecting frame 404. The rotating tube 407 drives the air blower 408 to rotate, and the air blower 408 generates an upward airflow, which blows the material transported to the diversion hood upward and guides it to the top of the connecting pipe 501. Qualified material falls into the collection box 303. After collection in the collection box 303, the qualified material can be removed by pulling the ring 302, thus completing the diversion and screening process.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
