Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a magnetic screening device for recycling waste aluminum. Background Technology

[0002] Aluminum ingots and blocks need to be smelted during processing. Since the scrap aluminum often contains metallic iron, such as the common "aluminum-clad iron" (steel-core aluminum stranded wire made of aluminum wire and steel wire), the smelted aluminum obtained after the scrap aluminum is smelted will also contain metallic iron, which leads to a decrease in purity.

[0003] Traditional magnetic separation equipment suffers from low efficiency due to its conventional magnetic separation method, resulting in long separation times, material accumulation, and the tendency for scrap aluminum to surround iron-containing materials, making it difficult to magnetically attract iron-containing materials. This reduces the iron removal effect, fails to remove iron ash, leads to lower purity, and lowers production quality.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by designing a magnetic screening device for waste aluminum recycling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic screening device for waste aluminum recycling includes a conical screening cylinder and a fixed frame. Fixed bearings are provided at both ends of the conical screening cylinder. A hollow rotating cylinder is located inside the conical screening cylinder. A drive shaft is installed at one end of the hollow rotating cylinder, and a hollow rotating rod is connected to the other end of the hollow rotating cylinder. The drive shaft and the hollow rotating rod extend out of the conical screening cylinder through the fixed bearings. Hollow guide plates are connected around the hollow rotating cylinder. Multiple arc-shaped electromagnetic plates are installed inside the hollow rotating cylinder. Fixed electromagnetic plates are installed inside the hollow guide plates. Two fixed connecting rods are installed on one side of the hollow guide plates. A stirring plate is installed at the end of the two fixed connecting rods away from the hollow guide plate, and one end of the stirring plate is in contact with the inner wall of the conical screening cylinder.

[0008] Furthermore, a motor bracket is installed at one end of the conical screening cylinder, and a drive motor is installed on the motor bracket. The output end of the drive motor is fixedly connected to the end of the drive shaft extending out of the conical screening cylinder, and an electric slip ring is provided at the end of the hollow rotating rod extending out of the conical screening cylinder.

[0009] Furthermore, the bottom of the conical screening cylinder is provided with multiple fixed through holes, a fixed base plate is installed on the fixed frame, a filter box is movably connected to the fixed base plate, the two ends of the filter box are provided with arc-shaped notches that match the conical screening cylinder, fixed limiting blocks are installed at the four corners inside the filter box, a filter screen is provided inside the filter box, the filter screen is located above the fixed limiting blocks, and multiple magnetic suction rods are provided on the filter screen.

[0010] Furthermore, a discharge port is provided on the lower side of one side of the conical screening cylinder, and a quick-opening gate is provided on the discharge port. A feed hopper is provided on the top of the conical screening cylinder.

[0012] Furthermore, the cable on the slip ring passes through the hollow rotating rod and enters the hollow rotating cylinder, connecting with the arc-shaped electromagnetic plate and the fixed electromagnetic plate.

[0013] Compared with existing technologies, this technical solution has the following beneficial effects:

[0014] By energizing the arc-shaped electromagnetic plate and the fixed electromagnetic plate, magnetic force is generated, which magnetically attracts the iron-containing material to the hollow guide plate and the hollow rotating drum, separating aluminum and iron.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] This utility model provides, for example Figure 1-5 The magnetic screening device for recycling waste aluminum shown includes a conical screening cylinder 1 and a fixed frame 2. Fixed bearings 3 are provided at both ends of the conical screening cylinder 1. A hollow rotating cylinder 4 is provided inside the conical screening cylinder 1. A drive shaft 5 is installed at one end of the hollow rotating cylinder 4, and a hollow rotating rod 6 is connected to the other end of the hollow rotating cylinder 4. The drive shaft 5 and the hollow rotating rod 6 pass through the fixed bearings 3 and extend out of the conical screening cylinder 1. Hollow guide plates 7 are connected around the hollow rotating cylinder 4. Multiple arc-shaped electromagnetic plates 8 are installed inside the hollow rotating cylinder 4. Fixed electromagnetic plates 9 are installed inside the hollow guide plates 7. Two fixed connecting rods 10 are installed on one side of the hollow guide plates 7. A stirring plate 11 is installed at the end of the two fixed connecting rods 10 away from the hollow guide plates 7. One end of the stirring plate 11 is in contact with the inner wall of the conical screening cylinder 1.

[0025] The material is poured into the conical screening cylinder 1. The drive shaft 5 drives the hollow rotating cylinder 4 to rotate. The hollow rotating cylinder 4 drives the hollow rotating rod 6 to rotate on the fixed bearing 3. The hollow rotating cylinder 4 drives the stirring plate 11 to rotate through the hollow guide plate 7 and the fixed connecting rod 10. The stirring plate 11 flips the material in the conical screening cylinder 1 upward. After the material rotates to the top, it falls onto the hollow guide plate 7. The arc-shaped electromagnetic plate 8 and the fixed electromagnetic plate 9 are energized to generate magnetic force, which magnetically attracts the iron-containing material to the hollow guide plate 7 and the hollow rotating cylinder 4, separating aluminum and iron, improving iron removal efficiency and screening effect.

[0026] Refer to the instruction manual appendix Figure 1 A motor bracket 12 is installed at one end of the conical screening cylinder 1, and a drive motor 13 is installed on the motor bracket 12. The output end of the drive motor 13 is fixedly connected to the end of the drive shaft 5 that extends out of the conical screening cylinder 1. An electric slip ring 14 is provided at the end of the hollow rotating rod 6 that extends out of the conical screening cylinder 1. The cable on the electric slip ring 14 passes through the hollow rotating rod 6 and enters the hollow rotating cylinder 4, where it is connected to the arc-shaped electromagnetic plate 8 and the fixed electromagnetic plate 9.

[0027] When the drive motor 13 starts working, the output end of the drive motor 13 drives the drive shaft 5 to rotate, and the drive shaft 5 drives the hollow drum 4 to rotate. The arc-shaped electromagnetic plate 8 and the fixed electromagnetic plate 9 are powered through the electric slip ring 14, which will not affect the rotation of the hollow drum 4.

[0028] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 5 The bottom of the conical screening cylinder 1 is provided with multiple fixed through holes 15. A fixed base plate 16 is installed on the fixed frame 2. A filter box 17 is movably connected to the fixed base plate 16. Both ends of the filter box 17 are provided with arc-shaped notches that match the conical screening cylinder 1. Fixed limit blocks 18 are installed at the four corners inside the filter box 17. A filter screen 19 is provided inside the filter box 17. The filter screen 19 is located above the fixed limit blocks 18. Multiple magnetic suction rods 20 are provided on the filter screen 19.

[0029] When the material inside the conical screening cylinder 1 is turned over, aluminum ash and iron ash fall through the fixed through hole 15 into the filter box 17. The aluminum ash and iron ash fall onto the filter screen 19, and the magnetic suction rod 20 magnetically attracts the iron ash. The aluminum ash passes through the filter screen 19 and is collected in the filter box 17, which improves the iron removal effect, improves the purity of aluminum, and improves the production quality.

[0030] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The cone-shaped screening cylinder 1 has a discharge port 21 on one side of the lower part, and a quick-opening gate 22 on the discharge port 21. The cone-shaped screening cylinder 1 has a feed hopper 23 on the top.

[0031] The material is poured into the conical screening cylinder 1 through the feed hopper 23. After the material is screened to remove iron, the quick-opening gate 22 is opened to open the discharge port 21. The material slides towards the discharge port 21 for easy discharge.

[0032] Refer to the instruction manual appendix Figure 3 There are six hollow guide plates 7, and the hollow guide plates 7 are set at an angle.

[0033] The hollow guide plate 7 is set at an angle. The material slides the hollow guide plate 7 in a downward tilting direction and is conveyed to the narrow opening of the conical screening cylinder 1. The material then moves from the narrow opening to the wide opening, which can completely disperse the material, avoid material accumulation, and improve the screening effect.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
