[0016] This application discloses a device for crushing recycled aluminum raw materials. (Refer to...) Figure 1 The system includes a crushing chamber 1, with a feed inlet 2 at the top to facilitate the feeding of recycled aluminum raw materials into the crushing chamber 1 for crushing. A feed hopper 3 is detachably and fixedly connected to the crushing chamber 1 at the feed inlet 2 by bolts. The feed hopper 3 is funnel-shaped to facilitate the placement of recycled aluminum raw materials, allowing them to quickly enter the crushing chamber 1 through the feed inlet 2 for crushing.

[0017] Reference Figure 1 , Figure 2A left crushing roller 7 and a right crushing roller 10 are rotatably connected inside the crushing box 1, allowing them to rotate relative to the crushing box 1. Specifically, two pairs of support bearings 4 are detachably fixed to the outer wall of the crushing box 1 by bolts, forming a whole with the support bearings 4. A first rotating shaft 6 and a second rotating shaft 9 are welded to the left crushing roller 7 and the right crushing roller 10, respectively, forming a whole and enabling simultaneous rotation. The first rotating shaft 6 and the second rotating shaft 9 pass through the crushing box 1 and are interference-fitted to the two pairs of support bearings 4, supporting and limiting the first rotating shaft 6 and the second rotating shaft 9, allowing them to rotate relative to the crushing box 1, thereby enabling the left crushing roller 7 and the right crushing roller 10 to rotate relative to the crushing box 1.

[0018] Reference Figure 1 , Figure 2 The left crushing roller 7 and the right crushing roller 10 are detachably fixed with several left crushing teeth 8 and right crushing teeth 11 by bolts, so that the left crushing teeth 8 and right crushing teeth 11 are connected to the left crushing roller 7 and the right crushing roller 10 to form a whole, thereby achieving simultaneous rotation. The left crushing teeth 8 and right crushing teeth 11 work together to crush the recycled aluminum raw material. The left crushing teeth 8 and right crushing teeth 11 are evenly connected in rows on the left crushing roller 7 and the right crushing roller 10, and the left crushing teeth 8 and right crushing teeth 11 are staggered. When the left crushing roller 7 and the right crushing roller 10 rotate, the left crushing teeth 8 and right crushing teeth 11 are driven to rotate on the first rotating shaft 6 and the second rotating shaft 9, thereby using the staggered left crushing teeth 8 and right crushing teeth 11 to crush the recycled aluminum raw material.

[0019] Reference Figure 1 , Figure 3A drive assembly is connected to the crushing box 1, which simultaneously drives the left crushing roller 7 and the right crushing roller 10 to rotate relative to each other. This allows the drive assembly to drive the left and right crushing rollers 7 and 10 to rotate simultaneously, thus crushing the recycled aluminum raw material. The drive assembly includes a drive motor, a first gear 12, a second gear 13, a third gear 15, and a fourth gear 17. The first gear 12 and the second gear 13 are detachably fixed to one end of the first rotating shaft 6 and the second rotating shaft 9, respectively, by bolts, enabling simultaneous rotation. A support block 5 is detachably fixed to the crushing box 1 by bolts, connecting the support block 5 to the crushing box 1 to form a single unit. The drive motor is detachably fixed to the support block 5 by bolts, connecting the drive motor to the support block 5, and thus to the crushing box 1. The output shaft of the drive motor is detachably fixed to the first rotating shaft 6 by a coupling, allowing the drive motor to operate and its output shaft to drive the first rotating shaft 6 to rotate. The outer wall of the crushing chamber 1 is detachably and fixedly connected to a first bearing and a second bearing by bolts, connecting the first bearing and the second bearing to the crushing chamber 1 to form a whole. The first bearing and the second bearing are interference-fitted to a third rotating shaft 14 and a fourth rotating shaft 16, respectively, connecting the third rotating shaft 14 and the fourth rotating shaft 16 to the crushing chamber 1 via the first bearing and the second bearing, thus supporting the third rotating shaft 14 and the fourth rotating shaft 16 without affecting their rotation relative to the crushing chamber 1. A third gear 15 and a fourth gear 17 are detachably and fixedly connected to the third rotating shaft 14 and the fourth rotating shaft 16 by bolts, respectively, allowing the lifting gear and the fourth gear 17 to rotate simultaneously. The first gear 12 meshes with the third gear 15, the second gear 13 meshes with the fourth gear 17, and the third gear 15 meshes with the fourth gear 17, so that the first gear 12, the second gear 13, the third gear 15 and the fourth gear 17 are meshed together. Thus, when the drive motor is energized, its output shaft drives the first rotating shaft 6 to rotate, thereby driving the first gear 12 to rotate. The first gear 12 drives the second gear 13 to rotate through the third gear 15 and the fourth gear 17. The second gear 13 drives the second rotating shaft 9 to rotate, thereby realizing that the left crushing roller 7 and the right crushing roller 10 rotate relative to each other at the same time. Then, the left crushing tooth 8 and the right crushing tooth 11 on the left crushing roller 7 and the right crushing roller 10 are used to crush the recycled aluminum raw material.

[0020] Reference Figure 1A support rod 18 is detachably and fixedly connected to the crushing box 1 below the left crushing roller 7 and the right crushing roller 10 by bolts, so that the support rod 18 is connected to the crushing box 1. A crushing motor 19 is detachably and fixedly connected to the support rod 18 by bolts, so that the crushing motor 19 is connected to the support rod 18, and then to the crushing box 1. A fixing block 20 is detachably and fixedly connected to the output shaft of the crushing motor 19 by bolts, so that the output shaft of the crushing motor 19 is connected to the fixing block 20, so that the output shaft of the crushing motor 19 drives the fixing block 20 to rotate simultaneously. Several crushing blades 21 are detachably and fixedly connected to the fixing block 20 by bolts, so that the crushing blades 21 are connected to the fixing block 20 and rotate simultaneously, so that the rotation of the crushing blades 21 performs secondary crushing on the recycled aluminum crushed at the left crushing roller 7 and the right crushing roller 10, thereby improving the crushing efficiency of the recycled aluminum raw material.

[0021] Reference Figure 1 The crushing box 1 below the support rod 18 has a conveying opening 22, and a perforated conveyor belt 23 is provided at the conveying opening 22. The perforated conveyor belt 23 is connected to the belt conveyor, so that the crushed recycled aluminum is received by the perforated conveyor belt and then conveyed to the crushing box 1. At the same time, the perforated conveyor belt 23 can filter the wastewater and recycled aluminum fragments in the recycled aluminum, which is convenient for the subsequent processing of the recycled aluminum fragments.

[0022] Reference Figure 1 The bottom of the crushing box 1 is provided with a drain port 24, which facilitates the discharge of sewage collected at the bottom of the crushing box 1. The bottom of the crushing box 1 is arc-shaped, and the drain port 24 is located in the middle of the arc-shaped bottom of the crushing box 1, so that the sewage falling through the arc-shaped bottom of the crushing box 1 can be quickly collected and discharged from the crushing box 1 through the drain port 24.

[0023] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the structural settings, working methods or control methods involved are all conventional settings, working methods or control methods in the art unless otherwise specified.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
