[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 3 As shown, a screening device for processing corundum includes an outer shell 1, a screening mechanism 2 is rotatably provided inside the outer shell 1, one end of the screening mechanism 2 is connected to a mounting plate 1 3, and the other end of the screening mechanism 2 is connected to a mounting plate 2 4. The lower end of the outer shell 1 is rotatably connected to a base 6 via a rotating shaft seat 5, and the lower end of the outer shell 1 is hingedly connected to a telescopic rod 7, and the other end of the telescopic rod 7 is rotatably connected to the base 6; the outer side surfaces of the mounting plate 1 3 and the mounting plate 2 4 are both mounted with rollers 8, and the rollers 8 mounted on the same side rotate along a circular track 9;

[0023] In this embodiment, when the device is used to screen corundum, the corundum is first loaded into the screening mechanism 2, and the screening mechanism 2 is driven to rotate in the outer shell 1, thereby driving the raw materials to roll in the screening mechanism 2, so that the corundum is screened one level at a time through the screen drum 1 21, the screen drum 2 22, and the screen drum 3 23. After screening, the outer shell 1 and the screening mechanism 2 are tilted around the rotating shaft seat 5 and the base 6 by extending the telescopic rod 7, so that the screened corundum is discharged from the screening mechanism 2 through the side of the mounting plate 2 4, which facilitates discharging and improves screening efficiency.

[0024] The screening mechanism 2 is installed in the outer shell 1 in a rotating manner. After the raw materials are put into the screening mechanism 2, the raw materials can be rolled in the screening mechanism 2 by the rotation of the screening mechanism 2, and then screened by the arranged level-by-level screen drums. In the screening process, the outer shell 1 and the screening mechanism 2 can be tilted through the rotating shaft seat 5 and the base 6 by extending the telescopic rod 7. Through the tilting structure, the raw materials screened in the screen drum can be discharged from the side of the mounting plate 2 4, which is convenient for the discharge of the raw materials after screening and prevents them from being accumulated in the screen drum.

[0025] See also Figure 2 As shown, the screening mechanism 2 includes a sieve drum 1 21, a sieve drum 2 22 is sleeved on the outside of the sieve drum 1 21, and a sieve drum 3 23 is sleeved on the outside of the sieve drum 22. The sieve drum 1 21, the sieve drum 2 22 and the sieve drum 3 23 screen the particles from large to small.

[0026] The screening mechanism 2 is divided into multiple sieve cylinders with different screening diameters, so that the product can be screened multiple times in one screening device, which is convenient for screening out multiple products with different particle sizes at one time, improving screening efficiency and increasing production capacity;

[0027] Since the corundum particle size screened by sieve drum 1 21 is the largest, the raw materials need to be loaded into sieve drum 1 21 when loading. After screening by sieve drum 1 21, particles larger than the sieve aperture of sieve drum 1 21 remain in sieve drum 1 21, and particles smaller than the sieve aperture of sieve drum 1 21 fall into sieve drum 2 22, and so on. After screening by sieve drum 22, sieve drum 3 23 is used for screening. After layers of screening, corundum products of different particle sizes are selected.

[0028] One end of the sieve drum 1 21, the sieve drum 2 22, and the sieve drum 3 23 of the screening mechanism 2 is fixedly mounted on the mounting plate 1 3, and the other end of the sieve drum 1 21, the sieve drum 2 22, and the sieve drum 3 23 is provided with a clamping groove 24, which is engaged with a clamping block 25, which is fixedly mounted on the inner side of the mounting plate 2 4;

[0029] In this embodiment, mounting plate 1 3 and mounting plate 2 4 are respectively rotated along track 9 by roller 8, ensuring that the screening mechanism 2 can be rotated in the outer shell 1 relying on mounting plate 1 3 and mounting plate 2 4, and has good stability during rotation. In addition, one end of screen drum 1 21, screen drum 2 22 and screen drum 3 23 of the screening mechanism 2 is fixed to mounting plate 1 3 by bolts, and the other end is clamped and connected to mounting plate 2 4 by clamping groove 24 and clamping block 25. On the one hand, it can facilitate the connection between the screening mechanism 2 and mounting plate 1 3 and mounting plate 2 4, and on the other hand, it can facilitate the disassembly between mounting plate 2 4 and the screening mechanism 2, so as to facilitate the replacement of the screening mechanism 2.

[0030] See also Figure 1 and Figure 3 As shown, a feed port 31 is provided on the inner side of the mounting plate 1 3 , and a connecting structure is formed between the feed port 31 and the screen drum 1 21 . The feed port 31 is connected to the upper hopper 11 , and the lower end of the outer shell 1 is connected to the slag discharge port 12 ;

[0031] A feed port 31 is opened on the feed port 31 and is connected with the screen drum 1 21, so that the upper hopper 11 can extend into the screen drum 1 21 through the feed port 31 and fill the screen drum 1 21 with raw materials, thereby improving the convenience of loading. The lower end of the outer shell 1 is connected with a slag discharge port 12. Since the waste residue screened by the screen drum 3 23 of the screening mechanism 2 will pass through the screen drum 3 23 and fall into the outer shell 1, the waste residue in the outer shell 1 can be discharged through the slag discharge port 12.

[0032] The outer side of the second mounting plate 4 is respectively provided with an extension cylinder 1 41, an extension cylinder 2 42 and an extension cylinder 3 43. The extension cylinder 1 41 is connected to the sieve cylinder 1 21, the extension cylinder 2 42 is connected to the sieve cylinder 2 22, and the extension cylinder 3 43 is connected to the sieve cylinder 3 23.

[0033] The lengths of the three screen cylinders in the screening mechanism 2 can be increased by extending the first, second and third cylinders 41, 42 and 43. When discharging materials at an angle, the screened raw materials can flow out separately through the extension cylinders for easy collection and to prevent them from being mixed together again.

[0034] The arc surface of the mounting plate 1 3 is provided with teeth, and the top of the mounting plate 1 3 is connected to the driving gear 32 through the teeth meshing, and the driving gear 32 is connected to the output shaft of the driving motor 33;

[0035] The driving motor 33 drives the driving gear 32 to rotate, and since the driving gear 32 is meshed with the mounting plate 3, the mounting plate 3 can be driven to rotate, and then the screening mechanism 2 can be driven to rotate, thereby screening the corundum by rotation.

[0036] Working principle: when corundum is screened by this device, the corundum is first loaded into the screening mechanism 2, and the screening mechanism 2 is driven to rotate in the outer shell 1, thereby driving the raw material to roll in the screening mechanism 2, so that the corundum is screened through the screen cylinder 1 21, the screen cylinder 2 22 and the screen cylinder 3 23 one level at a time. After screening, the outer shell 1 and the screening mechanism 2 are driven to tilt around the rotating shaft seat 5 and the base 6 by extending the telescopic rod 7, so that the screened corundum is discharged from the screening mechanism 2 through the side of the mounting plate 2 4, which is convenient for discharging and improves the screening efficiency.
