[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described are only part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] The vanadium-titanium slag crushing system provided by the utility model is now described.

[0023] like Figure 1 and Figure 2 As shown, one embodiment of the utility model provides a vanadium-titanium slag crushing system, including a box body 1, with a feed port 11 on the top and a discharge port 12 at the bottom of the box body 1; it also includes a primary crushing component 2 and a secondary crushing component 3 arranged in the box body 1 from top to bottom, and a return port 13 is provided on one side of the box body 1, and the return port 13 is located between the primary crushing component 2 and the secondary crushing component 3; the discharge port 12 at the bottom of the box body 1 is connected to a screening mechanism 4, and the screening mechanism 4 is used to screen the crushed vanadium-titanium slag into three types: large blocks, small blocks and particles. A large block recovery box 5, a small block recovery box 6 and a particle concentration box 7 are provided below the screening mechanism 4.

[0024] Compared with the prior art, the vanadium-titanium slag crushing system provided in this embodiment performs double crushing of the vanadium-titanium slag fragments through the primary crushing component 2 and the secondary crushing component 3, thereby improving the crushing effect of the vanadium-titanium slag, and screens the crushed vanadium-titanium slag into three categories of different sizes through the screening mechanism 4. The vanadium-titanium slag particles that meet the requirements are concentrated in the particle concentration box 7 for subsequent grinding, and the slightly larger vanadium-titanium slag are concentrated in the large-piece recovery box 5 so as to be poured into the feed port 11 again for double crushing, and the slightly smaller vanadium-titanium slag are concentrated in the small-piece recovery box 6 so as to be poured into the return port 13 again for one-time crushing. This system can crush the vanadium-titanium slag fragments more thoroughly, thereby improving the crushing effect.

[0025] like Figures 1 to 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0026] The primary crushing assembly 2 includes two primary crushing rollers 21 and a primary motor 22. The two primary crushing rollers 21 are rotatably connected in the box body 1 and mesh with each other. The primary motor 22 is arranged outside the box body 1, and the output shaft of the primary motor 22 is coaxially fixed with the primary crushing rollers 21.

[0027] The first-stage motor 22 is started to rotate the two first-stage crushing rollers 21, thereby crushing the vanadium-titanium slag fragments, thereby improving the first-stage crushing efficiency of the vanadium-titanium slag fragments.

[0028] like Figures 1 to 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0029] The secondary crushing assembly 3 includes multiple secondary crushing rollers 31 and a secondary motor 32. Adjacent secondary crushing rollers 31 are rotatably connected in the box body 1 and mesh with each other. The secondary motor 32 is arranged outside the box body 1, and the output shaft of the secondary motor 32 is coaxially fixed with the secondary crushing rollers 31.

[0030] By starting the secondary motor 32 to rotate the multiple secondary crushing rollers 31, the vanadium-titanium slag after the primary crushing can be subjected to secondary crushing, thereby improving the secondary crushing efficiency of the vanadium-titanium slag fragments.

[0031] like Figures 2 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0032] The screening mechanism 4 includes a fixed cylinder 41, a roller 42, a spiral auger 43, a screening motor 44 and a secondary screening assembly 45; the fixed cylinder 41 is connected to the discharge port 12, the roller 42 is coaxially connected to one end of the fixed cylinder 41, the spiral auger 43 is coaxially connected to the fixed cylinder 41 and the roller 42, and the screening motor 44 is arranged on the outside of the roller 42 and is coaxially fixed with the spiral auger 43; a plurality of primary sieve holes 421 are provided on the outer peripheral surface of the roller 42, and the large block recovery box 5 is located below the end of the roller 42 away from the fixed cylinder 41; the secondary screening assembly 45 is arranged below the roller 42, and the secondary screening assembly 45 is used to screen small pieces of vanadium-titanium slag and granular vanadium-titanium slag.

[0033] The crushed vanadium and titanium fall into the fixed cylinder 41, and the screening motor 44 is started to rotate the spiral auger 43, and the spiral auger 43 drives the vanadium and titanium slag to be transported in the direction away from the fixed cylinder 41. At the same time, during the transportation process, the vanadium and titanium slag smaller than the diameter of the first-level sieve hole 421 falls into the secondary screening component 45, and the large pieces of vanadium and titanium slag larger than the first-level sieve hole 421 are pushed out of the drum 42 and fall into the large piece recovery box 5, which improves the efficiency of screening and recovering the large pieces of vanadium and titanium slag remaining after crushing.

[0034] like Figures 2 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0035] The secondary screening assembly 45 includes a semi-annular support 451 and a spiral conveying blade 452. The semi-annular support 451 is coaxially arranged below the drum 42. A number of secondary sieve holes 4511 are opened on the semi-annular support 451. The diameter of the secondary sieve holes 4511 is smaller than that of the primary sieve holes 421; the spiral conveying blade 452 is coaxially wound on the outer peripheral surface of the drum 42, and the spiral conveying blade 452 is used to convey the vanadium-titanium slag in the semi-annular support 451; the screening mechanism 4 also includes a linkage assembly 46 arranged between the screening motor 44 and the drum 42, and the linkage assembly 46 is used to drive the drum 42 to reverse while the screening motor 44 drives the spiral auger 43 to rotate; the small piece recovery box 6 is located below the end of the semi-annular support 451 away from the large piece recovery box 5, and the particle concentration box 7 is located directly below the semi-annular support 451.

[0036] After passing through the primary sieve hole 421, the vanadium-titanium slag falls into the semi-annular support drum 451. The screening motor 44 drives the spiral auger 43 to rotate, and at the same time, drives the roller 42 to reverse through the linkage component 46, so that the spiral conveying blade 452 outside the roller 42 drives the vanadium-titanium slag in the semi-annular support drum 451 to be conveyed in the opposite direction of the vanadium-titanium slag in the roller 42. At the same time, the vanadium-titanium slag in the semi-annular support drum 451 is screened through the secondary sieve hole 4511, and the granular vanadium-titanium slag falls into the particle collection box 7 through the secondary sieve hole 4511. Small pieces of vanadium-titanium slag cannot pass through the secondary sieve hole 4511, and are pushed out of the semi-annular support drum 451 by the spiral conveying blade 452 and fall into the small piece recovery box 6, thereby improving the efficiency of screening and recovering the small pieces and granular vanadium-titanium slag remaining after crushing.

[0037] like Figures 3 and 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0038] The linkage assembly 46 includes a sun gear 461, a ring gear 462, multiple planetary gears 463 and multiple connecting rods 464. The sun gear 461 is coaxially fixed on the output shaft of the screening motor 44, and the ring gear 462 is coaxially arranged on the outside of the sun gear 461. The planetary gears 463 are engaged between the sun gear 461 and the ring gear 462, and the rotating shaft of the planetary gear 463 is stationary. The connecting rod 464 is fixed between the drum 42 and the ring gear 462.

[0039] The screening motor 44 drives the spiral auger 43 to rotate while driving the sun gear 461 to rotate. The sun gear 461 drives the ring gear 462 to reverse through multiple planetary gears 463. The ring gear 462 drives the drum 42 to rotate through multiple connecting rods 464, thereby improving the effect of the spiral auger 43 and the drum 42 rotating in opposite directions at the same time.

[0040] Furthermore, the connecting rod 464 is cylindrical, which can avoid vanadium-titanium slag from remaining on the connecting rod 464 as much as possible.

[0041] like Figure 1 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0042] A protective cover 8 is provided above the screening mechanism 4 , which can shield the roller 42 and the semi-annular support 451 , and prevent foreign objects from clogging the primary sieve holes 421 and the secondary sieve holes 4511 as much as possible.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
