Those skilled in the art will appreciate that terms such as "first," "I," and "step" in the present invention are merely used to distinguish between different steps, devices, or modules, and do not represent any specific technical meanings, nor do they necessarily indicate a logical order between them.

[0020] like Figure 1 、 2 As shown, according to an exemplary embodiment of the present invention, an aluminum ash and aluminum particle separation device is disclosed, including: an induction coil group 10, a conveying device 20, a fan I 30, a material baffle 40, a fan II 50, a fan III 60, an aluminum ash hopper 70, and an aluminum block hopper 80.

[0021] The induction coil assembly 10 includes a connecting wire 11 and a conical coil 12. The conical coil 12 is configured with a large diameter at the top and a small diameter at the bottom.

[0022] Here, the induction coil assembly 10 can serve as the internal structure of a levitation smelting furnace (not shown). As part of the levitation smelting furnace, it utilizes electromagnetic induction to generate a high-frequency magnetic field through high-frequency current. This induces an induced current and an opposing magnetic field in the metal within the coil, generating a repulsive force that causes the metal (conductor) to levitate in space. Since aluminum ash is non-conductive, while aluminum pellets are conductive, the aluminum ash can be separated by falling during the levitation of the aluminum pellets, as described below. To this end, the conical coil 12 constitutes a levitation coil. When energized, the levitation coil generates an upward electromagnetic force, causing the aluminum pellets within it to levitate.

[0023] In some embodiments, the induction coil assembly 10 requires a resistance power between 50 kW and 500 kW, a voltage range of 220 V to 500 V, a frequency of 4000 Hz to 9000 Hz, and a temperature of 1200° C. to 1800° C.

[0024] The conveying device 20 includes an inlet 21, a distribution hopper 22, a conveyor belt 23, and an outlet 24. The aluminum ash and aluminum pellet mixture can be transported to the induction coil assembly 10 through the conveying device 20.

[0025] In some embodiments, the feed port 21 is located at the bottom of the belt conveyor (corresponding to the conveyor device 20) and is an iron container for discharging materials. It is made of 45# steel plate with a thickness of 3 (±0.02) mm. The specific dimensions depend on the actual model and actual conditions of the belt conveyor. The distribution hopper 22 is mounted on the conveyor belt 23 and reinforced with bolts. It is made of C70 high-carbon steel plate with a thickness of 5 (±0.3) mm. The distribution hopper 22 has a total height of 110 (±0.3) mm and is perpendicular to the conveyor belt 23 and evenly distributed on the conveyor belt 23. Each time, 30-40 kg of a mixture of aluminum ash and aluminum particles can be discharged from the feed port 21. The conveyor belt 23 is made of chloroprene rubber (CR), and the belt length is determined by the size of the belt conveyor. It can be powered by a 2000W-3000W motor to drive the drive wheel.

[0026] Fan I 30 is installed to the upper right of the vertical line where the aluminum melt falls from the induction coil assembly 10, at a height of 800 (±10) mm from the induction coil assembly 10. It has a power rating of 1200W-1500W and a wind speed of 6-10 m / s. Of course, the installation location is not limited to the upper right; it can also be located in the upper left, as long as the air outlet of Fan I 30 is oriented toward the vertical line and the material retaining plate 40 on the other side of the vertical line.

[0027] The baffle plate 40 includes a vertical plate 41 for preventing the fallen aluminum ash from floating horizontally, and an inclined plate 42 for conveying the aluminum ash to the aluminum ash hopper 70.

[0028] In some embodiments, the material of the retaining plate 40 is 304 stainless steel with a thickness of 5 (±0.5) mm. The inclined plate 42 is angled at 45°-47° relative to the horizontal and at 135°-138° relative to the vertical plate 41. The dimensions of the inclined plate 42 are: 3500 (±10) mm in length and 2800 (±10) mm in width. The specifications of the vertical plate 41 are: 800 (±10) mm in height and 2800 (±10) mm in width.

[0029] Fans II 50 and III 60 are installed on either side of the vertical line of the aluminum melt, ensuring comprehensive cooling while maintaining a consistent downward direction. They are preferably located below the baffle plate 40 but above the aluminum block hopper 80. Fans II 50 and III 60 must meet the same design specifications, including brand and power. Power: 1500W-2000W, wind speed: 15-20m / s. Fans II 50 and III 60 should be installed on the same horizontal plane, with their exhaust ports facing each other and approximately 1200 (±10) mm from the induction coil assembly 10. Each fan should be 1200 (±10) mm from the vertical line of the aluminum melt.

[0030] The aluminum ash hopper 70 is generally arranged below the inclined plate 42, for example, placed below and to the left of the vertical line of the aluminum solution falling, and is preferably arranged corresponding to the lower end side of the inclined plate 42 to receive the aluminum ash sliding down from the inclined plate 42.

[0031] Thus, the fan I30 can be installed to the upper right or obliquely above the vertical line where the aluminum solution falls from the induction coil assembly 10, and the aluminum ash hopper 70 can be placed to the lower left or obliquely below the vertical line where the aluminum solution falls.

[0032] The aluminum block hopper 80 is arranged corresponding to the falling direction of the aluminum solution and is placed at the falling point of the aluminum solution (that is, the material port is perpendicular to the conical coil 12 of the induction coil group 10), and is generally located below the baffle plate 40 and the fan I 30.

[0033] In some embodiments, both the aluminum ash hopper 70 and the aluminum block hopper 80 have square top openings, facilitating the reception of aluminum ash and aluminum blocks. The aluminum ash hopper 70 is made of 45# steel plate with a thickness of 10 (±1) mm. Specific dimensions: top opening side length 2500 (±10) mm, height 1200 (±10) mm. The aluminum block hopper 80 is made of 304 stainless steel plate with a thickness of 10 (±1) mm. Specific dimensions: top opening side length 1600 (±3) mm, height 1200 (±5) mm.

[0034] When the aluminum ash and aluminum particle separation device constructed in this way is in operation, the induction coil group 10 is energized, and the fans I 30, II 50, and III 60 are turned on. After the aluminum ash and aluminum particle mixture is dropped into the induction coil group 10 from the discharge port 24 via the conveyor 20, the pure aluminum ash is not affected by the magnetic field and falls directly, while the aluminum particles and the combination of aluminum particles and aluminum ash are suspended in the conical coil 12 and begin to melt. The aluminum melt formed after the metallic aluminum melts is suspended on the top, while the aluminum ash does not float up and falls naturally due to the action of gravity.

[0035] After the aluminum ash falls, it is blown from right to left by the fan I 30 onto the baffle plate 40. The aluminum ash slides from the baffle plate 40 into the aluminum ash hopper 70 and is completely collected by the aluminum ash hopper 70.

[0036] When the induction coil group 10 is left only suspended aluminum solution, cut off the power, and close the fan 130, the aluminum solution loses the function of suspension, and falls naturally under the force of gravity. In the process of falling of the aluminum solution, it is affected by the cooling of the blowing of the fan 50 and the fan 60, and becomes aluminum particles and aluminum blocks, and finally falls into the aluminum block hopper 80.

[0037] Beneficial effects; the device is compact in structure, and small in investment site. Most importantly, aluminum ash and aluminum particles can be separated by nearly 100%.

[0038] In the description of the present application, the meaning of "a plurality of" is two or more than two, unless otherwise expressly specifically limited. Unless otherwise expressly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be broadly understood, for example, can be fixedly connected, or can be detachably connected, or integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.
