Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A powder recycling and reuse device for a powder metallurgy production line includes a processing box 1, an air separation component 3 is provided at the bottom of the processing box 1, a discharge component 2 is provided on the right side of the air separation component 3, and a screen separation component 4 is provided inside the processing box 1.

[0026] The air separation assembly 3 includes a processing housing 301, a placement housing 302, a connecting cylinder 303, a connecting shaft 304, a baffle plate 305, a magnetic suction plate 306, a purification cotton 307, a U-shaped frame 308, and a magnet block 309. The processing housing 301 is fixedly connected to the bottom of the processing box 1, the placement housing 302 is fixedly connected to the left side of the processing housing 301, the connecting cylinder 303 is fixedly connected to the left side of the placement housing 302, a connecting ring is fixedly connected to the left side of the connecting cylinder 303, the baffle plate 305 is fixedly connected to the surface of the connecting shaft 304, and the magnetic suction plate 306 is fixedly connected to the baffle plate 305. At the bottom, the U-shaped frame 308 is fixedly connected to the inside of the connecting ring, the magnet block 309 is fixedly connected to the top center of the magnet block 309, the left side of the connecting ring is fixedly connected to the bearing, the connecting shaft 304 is fixedly connected to the inner ring of the bearing, the purification cotton 307 is inserted into the inside of the connecting ring, the diameter of the purification cotton 307 is adapted to the inner diameter of the connecting ring, the magnetic suction plate 306 is magnetically connected to the magnet block 309, when installing the purification cotton 307, the blocking plate 305 and the magnetic suction plate 306 can be rotated in the direction of the U-shaped frame 308 to contact and magnetically attract each other with the magnet block 309, which can facilitate the insertion of the purification cotton 307.

[0027] The screen separation assembly 4 includes an inner processing screen 401, a first connecting strip 402, a spring 403, a second connecting strip 404, and a vibration motor 405. The inner processing screen 401 is slidably connected to the inside of the processing box 1. The vibration motor 405 is fixedly connected to the bottom of the inside of the processing box 1. The bottommost inner processing screen 401 is connected to the top of the vibration motor 405. The second connecting strip 404 is fixedly connected to the front of the inner processing screen 401. The first connecting strip 402 is fixedly connected to the front of the inner processing screen 401. The spring 403 is fixedly connected to the top of the second connecting strip 404. The top area of ​​the second connecting strip 404 is equal to the bottom area of ​​the first connecting strip 402. The screen aperture of the inner processing screen 401 gradually decreases from top to bottom, which can ensure that powders of different particle sizes remain in different areas and ensure the normal operation of the device.

[0028] In use, the powder enters the processing chamber 1 through the top feeding assembly. A multi-layered stepped screen device is installed at the bottom of the processing chamber 1. When in use, the vibration motor 405 below is activated. After the mixed powder is poured in through the top feeding port, the smaller particles pass through the upper screen first under vibration, while the larger particles remain in the upper layer. Powders of different sizes remain in different areas. The powder that meets the requirements can then be screened and poured out from the bottom of the processing chamber 1 into the processing housing 301 for further air separation. The screen separation assembly 4 enables precise powder grading and is easy to use. Dust falling into the processing housing 301 can undergo density separation. The left connecting cylinder 303 is activated. An internal fan generates a rightward airflow, and the strong airflow generated by the centrifugal impeller blows the powder up. Because powders of different densities experience different forces in the airflow, impurities or light powders with lower density are carried by the airflow to the exhaust port on the side wall of the air classifier chamber and discharged, while metal powders with higher density move towards the edge of the air classifier chamber due to centrifugal force, thus achieving the separation of powders of different densities. A filter assembly is set on the left side. When in use, the blocking plate 305 can be rotated in the direction of the U-shaped frame 308 to allow the magnetic plate 306 to contact and magnetically attract the magnet block 309 together, which can easily insert the purification cotton 307. After insertion, the blocking plate 305 is returned to its original position to form a barrier, which can purify the incoming air and prevent impurities from entering the interior and affecting the air classifier, ensuring the effectiveness of the device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
