[0018] To make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Referring to Figure 1 , the present utility model provides an aluminum ash screening machine, which includes a frame 1, on which a magnetic separation mechanism 2, a motor 3, a screening mechanism 4 and a drive shaft 5 are installed. The output shaft of the motor 3 is directly connected to the drive shaft 5 and the input shaft 6 of the magnetic separation mechanism 2. Through a single motor drive, the linkage of magnetic separation and screening is realized. The discharge port of the magnetic separator 2 is communicated with the feed port of the screening mechanism 4. After the aluminum ash powder removes the iron impurities contained therein through the magnetic separation mechanism 2, it enters the screening mechanism 4 for step-by-step screening.

[0020] Referring to Figure 2 、 Figure 3 , the magnetic separation mechanism 2 consists of a feed trough 201, a drum 202, an input shaft 6 and a telescopic magnetic rod 7. The lower end of the feed trough 201 is communicated with the feed port of the screening mechanism 4. The drum 202 is installed inside the feed trough 201. The input shaft 6 consists of an inner shaft 601 and a shaft sleeve 602. The shaft sleeve 602 is sleeved at both ends of the inner shaft 601. The inner shaft 601 is fixed on the frame, and the shaft sleeve 602 is used to connect the drum 202 and the output shaft of the motor 3. The telescopic magnetic rod 7 is installed on the wall of the drum 202. On a section of the inner shaft 601 inside the drum 202, a semi-cylindrical top block 603 is provided. When the drum 202 rotates with the rotation of the motor 3, the top block 603 will push the telescopic magnetic rod 7 out of the inside of the drum 202;

[0021] The telescopic magnetic rod 7 includes a telescopic sleeve 702 and a magnetic rod 701. The telescopic sleeve 702 is fixedly installed on the inner wall of the drum 202. Usually, the telescopic sleeve 702 is arranged along the radial direction of the drum 202. The magnetic rod 701 can be telescoped inside the telescopic sleeve 702. A limit seat 703 is fixed at the lower part of the magnetic rod 701. A return spring 704 is installed between the telescopic sleeve 702 and the limit seat 703 to ensure that the magnetic rod 701 can be stably extended and retracted. A ball 705 is also provided at the lower end of the magnetic rod 701 to reduce the friction between the magnetic rod 701 and the top block 603 and improve the service life of the equipment.

[0022] The aluminum ash powder is put into the upper part of the feed trough 201. As the drum 202 rotates, the magnetic rod 701 extends out of the drum 202 under the action of the top block 603, and adsorbs the iron-containing impurities therein; after the lower end of the magnetic rod 701 is separated from the contact with the top block 603, the magnetic rod 701 retracts under the action of the return spring 704, thereby separating the iron impurities adsorbed thereon. The ferromagnetic impurities fall into the iron discharge trough 203, realizing the separation of ferromagnetic impurities.

[0023] The magnetic rod 701 rotates with the roller 202, which can stir and disperse the aluminum ash powder. At the same time, since the magnetic rod 701 penetrates into the aluminum ash powder, the separation effect of iron impurities in the aluminum ash powder is better than that of conventional equipment.

[0024] Refer to Figure 3 , Figure 4 :

[0025] The screening mechanism 4 mainly consists of a housing 401 and a screen 404. An inclined slide rail 402 is arranged inside the housing 401, and the screen 404 is slidably installed on the slide rail 402. A pull rod 405 passing through the housing 401 is installed at the upper end of the screen 404. A side discharge chute 403 is installed on the housing 401 below the screen 404 for discharging the aluminum ash with larger particle size on the screen 404, and a bottom discharge chute 406 is arranged at the bottom of the housing 401 for discharging the aluminum ash with smaller particle size.

[0026] A crankshaft 501 is arranged on the drive shaft 5. The crankshaft 501 is connected to the pull rod 405 through a connecting rod 502. Both ends of the pull rod 405 are rotatably connected to the crankshaft 501 and the pull rod 405 respectively. When the motor 3 drives the drive shaft 5 to rotate, the crankshaft 501 rotates accordingly, and drives the screen 404 to reciprocate on the slide rail 402 through the connecting rod 502 and the pull rod 405, thereby realizing the screening of the aluminum ash powder.

[0027] In this embodiment, two screens 404 are sequentially arranged in the housing 401 from top to bottom for dividing the aluminum ash powder into three different particle size ranges; the crankshaft 501 is connected to the two pull rods 405 through the connecting rod 502 respectively. When the crankshaft 501 rotates, the two screens 404 can move synchronously, improving the screening efficiency.

[0028] The specific implementation manners of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
