[0027] Please see the appendix Figures 1 to 4As shown, this utility model provides a multi-stage crushing device for recycling electrolytic aluminum waste residue, including an outer shell 1, a feeding port 11 at the top of the outer shell 1, two sets of crushing rollers 2 rotatably arranged inside the outer shell 1, a screen plate 3 below the crushing rollers 2, and a guide plate 4 below the screen plate 3; a secondary crushing mechanism 5 is arranged on one side of the outer shell 1, the secondary crushing mechanism 5 includes an outer cover 51 fixedly installed on the outer shell 1, a rubbing plate 6 and a squeezing roller 7 are arranged inside the outer cover 51, one end of one set of crushing rollers 2 is connected to a drive motor 21, and the ends of the two sets of crushing rollers 2 away from the drive motor 21 are respectively provided with gear disks 22, and the two sets of gear disks 22 are connected by tooth meshing;
[0028] In this embodiment, when crushing electrolytic aluminum waste slag, the crystallized electrolytic aluminum waste slag blocks are fed into the outer shell 1 through the feeding port 11. Then, the electrolytic aluminum waste slag is crushed by the mutual squeezing of two sets of crushing rollers 2. The waste slag after being crushed by the crushing rollers 2 falls onto the screen plate 3 for screening. Smaller particles pass through the screen plate 3 into the guide plate 4 and are then discharged through the discharge port 41. The waste slag particles remaining on the screen plate 3 roll down with the inclination of the screen plate 3 and flow into the outer shell 51 of the secondary crushing mechanism 5 through the discharge port 31. Then, they are squeezed and crushed by the rubbing plate 6 and the squeezing roller 7 and then flow out through the opening at the lower end of the outer shell 51. After multiple stages of crushing, the particle size of the electrolytic aluminum waste slag is more uniform.
[0029] Preferably, the rotation of the two sets of crushing rollers 2 is first driven by a drive motor 21 to rotate one set of crushing rollers 2. The crushing rollers 2 of one set drive the gear disk 22 at the other end to rotate. The gear disk 22 drives the other set of gear disks 22 to rotate, thereby driving the other set of crushing rollers 2 to rotate. The crushing of the electrolytic aluminum waste is achieved by the extrusion of the electrolytic aluminum waste by the two sets of crushing rollers 2.
[0030] The screen plate 3 and the guide plate 4 are both inclined structures, and the inclination directions are opposite. A discharge port 31 is provided on the outer shell 1 at the bottom of the screen plate 3. The outer cover 51 is connected to the upper end of the screen plate 3 through the discharge port 31. A discharge port 41 is provided on the outer shell 1 at the bottom of the guide plate 4.
[0031] In this embodiment, the inclined structure of the screen plate 3 and the guide plate 4 allows the waste residue falling onto the screen plate 3 and the guide plate 4 to roll down along the inclined angle, facilitating the flow of the waste residue from the guide plate 4 to the discharge port 41 to complete the discharge, so that the waste residue on the screen plate 3 can roll into the secondary crushing mechanism 5.
[0032] Please see Figure 5 As shown, the surface of the rubbing board 6 facing the extrusion roller 7 has horizontal stripes 61.
[0033] Horizontal stripes 61 are set on the washboard 6, similar to the horizontal grooves set on a washboard, to increase the friction on the waste residue, prevent the waste residue from sliding down from the inside of the washboard 6, and facilitate the crushing of the waste residue.
[0034] The two ends of the extrusion roller 7 are rotatably connected to the outer cover 51 via a rotating shaft. The outer sides of the rotating shaft sleeves at both ends of the extrusion roller 7 are respectively connected to a telescopic rod 71 and a guide rod 72. The guide rod 72 passes through the connecting block 73. The connecting block 73 is fixedly connected to the outer cover 51. The outer end of the telescopic rod 71 is connected to the outer cover 51. One end of the extrusion roller 7 is also connected to a drive motor 74.
[0035] In this embodiment, the rotation of the extrusion roller 7 is driven by the second drive motor 74. When crushing electrolytic aluminum waste, the extrusion roller 7 is moved by the extension and retraction of the telescopic rod 71 according to the required particle size, thereby adjusting the distance between it and the rubbing plate 6 to facilitate the crushing of electrolytic aluminum waste with different particle sizes. When the extrusion roller 7 moves, it will drive the guide rod 72 to slide on the connecting block 73. The connection between the guide rod 72 and the connecting block 73 improves the stability of the extrusion roller 7 when it moves. In this embodiment, the outer side of the second drive motor 74 is connected to the guide rod 72.
[0036] In this device, drive motor 1 21 and drive motor 2 74 are controlled by a uniform control device, and the control device is a prior art, which will not be described in detail here.
[0037] The working principle of this utility model is as follows: When crushing electrolytic aluminum waste slag, the crystallized electrolytic aluminum waste slag blocks are fed into the outer shell 1 through the feeding port 11. Then, the electrolytic aluminum waste slag is crushed by the mutual squeezing of two sets of crushing rollers 2. The waste slag after being crushed by the crushing rollers 2 falls onto the screen plate 3 for screening. Smaller particles pass through the screen plate 3 and fall into the guide plate 4, and then are discharged through the discharge port 41. The waste slag particles remaining on the screen plate 3 roll down with the inclination of the screen plate 3 and flow into the outer shell 51 of the secondary crushing mechanism 5 through the discharge port 31. Then, they are squeezed and crushed by the rubbing plate 6 and the squeezing roller 7, and then flow out through the opening at the lower end of the outer shell 51. After multiple stages of crushing, the particle size of the electrolytic aluminum waste slag becomes more uniform.
[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
