Technical Field

[0001] This utility model relates to the field of PET bottle flake recycling technology, specifically to a metal separation device for PET bottle flakes. Background Technology

[0002] In existing technologies, PET bottle flakes need to be crushed and then the metals separated during recycling.

[0003] In the prior art, a Chinese patent document with authorization announcement number CN219190903U describes a metal separation device for PET bottle flakes. This patent includes a separation device body, a support leg fixedly connected to the lower surface of the separation device body, a feed inlet provided on the upper surface of the separation device body, a cylindrical barrel fixedly connected to the bottom surface of the separation device body, a motor installed on the lower surface of the cylindrical barrel, a rotating shaft fixedly connected to the output end of the motor, an auger blade fixedly connected to the surface of the rotating shaft, an opening and closing door hinged to the side of the separation device body, a through support plate provided on the side of the separation device body, a movable leg slidably connected to the surface of the support plate, a mounting plate fixedly connected to the upper surface of the movable leg, and an electromagnet mounted on the surface of the mounting plate.

[0004] The use of cited documents has the following drawbacks:

[0005] 1. The separated metal sheets cannot be continuously fed and need to be fed manually, which reduces production efficiency and ease of use;

[0006] 2. Because continuous feeding is not possible, after the electromagnet attracts a portion of the metal, the material is conveyed to the electromagnet again by the auger blade, and the material tends to remain on the upper part of the electromagnet.

[0007] Therefore, we propose a metal separation device for PET bottle flakes. Utility Model Content

The protective shell 5 is fixedly installed on one side of the outer surface of the multi-stage separator 1, and the motor 6 is fixedly installed on one side of the upper outer surface of the protective shell 5. A guide plate 17 is fixedly installed on one side of the upper part of the inner cavity of the multi-stage separator 1.

[0029] There are two sets of worm gears 8, worm wheels 9, driven shafts 10, and electromagnet rollers 11. Worms 8 and worm wheels 9 are located inside the protective housing 5. The rotating shaft 7 is connected to the lower outer surface of the motor 6. Two sets of worm gears 8 are fixedly installed on the outer walls of the upper and lower ends of the rotating shaft 7. Worm wheels 9 are located on one side of the outer surface of the worm gear 8 and are fixedly installed on the outer wall of one end of the driven shaft 10, with one end of the driven shaft 10 extending into the interior of the multi-stage separation chamber 1. One side of the outer surface of the worm gear 8 meshes with the worm wheel 9. Sealed bearings are installed between the rotating shaft 7, the driven shaft 10, and the protective housing 5. The rotating shaft 7 and the driven shaft 10 are rotatably connected to the protective housing 5 through the sealed bearings. A coupling is installed between the rotating shaft 7 and the motor 6. The upper outer surface of the rotating shaft 7 is fixedly connected to the lower outer surface of the output shaft in the motor 6 through the coupling.

A sealed bearing is provided between the driven shaft 10 and the multi-stage separation box 1, and the driven shaft 10 is rotatably connected to the multi-stage separation box 1 through the sealed bearing. The first semi-cylindrical electromagnet 12 is fixedly installed on one side of the outer surface of the second semi-cylindrical electromagnet 13. The third guide plate 22 is fixedly installed on the left side of the middle of the inner cavity of the multi-stage separation box 1, and the baffle plate 18 is fixedly installed in the middle of the inner cavity of the multi-stage separation box 1.

[0030] It should be noted that this utility model is a metal separation device for PET bottle flakes. The material to be separated is fed into the multi-stage separation box 1 through the feed inlet 2, and guided by the guide plate 17 into the electromagnet roller 11. At this time, the first semi-cylindrical electromagnet 12 is energized and attracts metal objects. When the first semi-cylindrical electromagnet 12 rotates to the position of the second semi-cylindrical electromagnet 13, the power is turned off, and the second semi-cylindrical electromagnet 13 is energized, so that the metal material is separated from the first semi-cylindrical electromagnet 12. Therefore, the electromagnet roller 11 attracts metal objects on the left side and separates them from the metal on the right side. The separated metal material is guided by the first guide plate 19 and falls to the bottom of the inner cavity of the multi-stage separation box 1 and is discharged through the metal discharge port 16. After the first screening, the material falls onto the third guide plate 22. Guided by the third guide plate 22 and the second guide plate 21, the material is fed through the feed port 23. The second guide plate 21 guides the material to the electromagnetic roller 11 at the bottom of the multi-stage separation box 1 for secondary screening. Then, non-metals are discharged through the non-metal discharge port 15, and metals are discharged through the metal discharge port 16. The operation of the motor 6 drives the rotating shaft 7 to rotate, which in turn drives the two sets of worm gears 8 to rotate. The worm gears 8 and worm wheels 9 mesh with each other, so that the worm gears 8 drive the driven shaft 10 to rotate through the worm wheels 9. The driven shaft 10 drives the electromagnetic roller 11 to rotate, thereby driving the two sets of electromagnetic rollers 11 to screen the material.
