[0024] The device includes:
[0025] A crushing box 10 is provided with a feed inlet 11 at the top and a discharge structure 12 at the bottom;
[0026] A crushing roller 21 is rotatably arranged inside the crushing box 10 and below the feed port 11, a screen 22 with low ends and high middle is arranged below the crushing roller 21, a falling channel is formed between the lower end of the screen 22 and the side wall of the crushing box 10, a crushing roller 23 is rotatably arranged below the falling channel, and a screen 24 is also arranged below the screen 22;
[0027] The mesh diameter of the second screen 24 is smaller than that of the first screen 22 , and the material passing through the second screen 24 and the material not passing through the second screen 24 are separately collected by the discharging structure 12 .
[0028] The aluminum slag material to be crushed is added from the feed port 11, and passes through the crushing roller 21, the screen 22, the crushing roller 23 and the screen 24 in sequence. The crushing roller 21 performs the primary crushing on the aluminum slag material, and the screen 22 performs the screening on the aluminum slag material after the primary crushing, so that particles with smaller diameters can directly pass through and fall onto the screen 24, while larger particles that have not been crushed fall from the falling channel to the crushing roller 23 to be crushed again. The aluminum slag material that has been crushed twice and that has fallen directly into the crushing roller 23 is finally collected separately through the screen 24;
[0029] By setting the crushing roller 21, the screen 22, the crushing roller 23 and the screen 24, the aluminum slag can be crushed and screened multiple times, and the size distribution of the particles can be controlled more accurately, so that more uniform and higher quality products can be produced and the crushing efficiency can be improved.
[0030] The crushing roller 1 21 and the crushing roller 2 23 respectively include roller bodies that can rotate in opposite directions. Both ends of the roller bodies are rotatably installed on the opposite inner walls of the crushing box 10. A driving component 30 is also provided on one of the outer side walls of the crushing box 10. The driving component 30 drives the two roller bodies of the crushing roller 1 21 and the crushing roller 2 23 to rotate synchronously and in opposite directions to crush the aluminum slag.
[0031] The driving assembly 30 includes a gear set corresponding to the crushing roller 1 21 and the crushing roller 2 23 respectively, and the gear set includes a gear 1 31 and a gear 2 32 that are meshed and connected. The gear 1 31 and the gear 2 32 are respectively connected to the two roller bodies, and a plurality of motors 33 are also arranged on the outer wall of the crushing box 10. The output shaft of each motor 33 is respectively connected to one of the crushing rollers 1 21 and 23.
[0032] The driving assembly 30 is provided to realize the rotational crushing function of the crushing roller 1 21 and the crushing roller 2 23. In this embodiment, Figure 3 As shown, the starting motor 33 drives the roller body connected thereto to rotate, the roller body drives the gear 2 32 to rotate, the gear 2 32 drives the gear 1 31 meshing therewith to rotate, thereby driving the roller body connected to the gear 1 31 to rotate.
[0033] like Figure 2 As shown, Figure 2 What is shown is a partial cross-sectional schematic diagram of a crushing device in an embodiment;
[0034] The second screen 24 is also configured to have a structure with low ends and a high middle, and the low ends of the second screen 24 are connected to the inner wall of the corresponding side of the crushing box 10, and the inner wall of the corresponding side of the crushing box 10 is provided with a discharge port 122 for discharging materials;
[0035] A discharge box 121 is provided at the bottom of the crushing box 10 and at a position corresponding to the position below the second screen 24;
[0036] A second discharge box 123 is provided below the discharge port 122;
[0037] The second screen 24 re-screens the materials that fall directly from the first screen 22 and are crushed again by the second crushing roller 23. The materials that cannot pass through the mesh of the second screen 24 are discharged from the discharge ports 122 at both ends and fall into the second discharge box 123 to be collected. The materials that can directly fall through the mesh of the second screen 24 are collected by the first discharge box 121.
[0038] The screen 24 is provided to collect materials of different particle sizes after crushing separately, so as to facilitate different subsequent treatments of materials of different particle sizes and to control the quality of the crushed products.
[0039] An inclined guide plate 26 is provided on the side wall of the crushing box 10 and below the second crushing roller 23, and one end of the guide plate 26 away from the side wall is lower than the other end;
[0040] The guide plate 26 guides the material and enables the material that has been crushed again by the crushing roller 23 to extend its rolling path when falling onto the screen 24 , so that the material can be fully screened by the screen 24 .
[0041] Working principle: When the device is in use, the aluminum slag material to be crushed is added from the feed port 11, and the material is first crushed by the crushing roller 21, and the initially crushed material falls onto the screen 22. At this time, particles with smaller diameters can directly pass through the mesh holes of the screen 22 and fall onto the screen 24, while larger particles that have not been crushed fall from the falling channel to the crushing roller 23 and are crushed again. The aluminum slag material after the secondary crushing and that falls directly into the crushing roller is finally screened by the screen 24, and the material that cannot pass through the mesh holes of the screen 24 is discharged from the discharge ports 122 at both ends and falls into the discharge box 2 123 to be collected, and the material that can directly pass through the mesh holes of the screen 24 and fall is collected by the discharge box 121.
[0042] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
