Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address the issue of location limitations hindering the molten aluminum feeding process in existing aluminum ash separation devices during practical use, please refer to [the relevant documentation]. Figures 1-5 This embodiment provides the following technical solution:

[0023] An aluminum ash separation device for waste aluminum recycling in this embodiment includes a device housing 1. A separation hopper 2 for separating aluminum ash is provided below the device housing 1. A dispensing paddle 104 is installed inside the upper part of the separation hopper 2. A lifting discharge column 3 is installed at the bottom end of the separation hopper 2. The lifting discharge column 3 extends to the outside of the separation hopper 2 and is slidably connected to the separation hopper 2. Hydraulic cylinders 202 are installed at both ends of the lifting discharge column 3.

[0024] In fact, the lifting and unloading column 3 extends into the unloading tray 201 and is sealed to the unloading tray 201. A connector 301 is installed at the lower end of the lifting and unloading column 3. Connecting arms 303 are installed on both sides of the lower end of the connector 301. A locking block 302 is installed at the upper end of the connecting arm 303. The locking block 302 is fixedly connected to the connector 301 and the connecting arm 303 respectively. The connector 301 is fixed by the connecting arm 303. The connector 301 and the connecting arm 303 are limited by the hydraulic cylinder 202 and move to drive the lifting and unloading column 3 to rise and fall, so as to realize the automated unloading operation.

[0025] The device housing 1 has an integrally formed feed inlet 101 at its front end, which is connected to the upper end of the separation hopper 2. When the aluminum ash separation device is in use, the waste aluminum to be separated is put into the feed inlet 101 and enters the separation hopper 2 for heating.

[0026] In addition, a servo motor 102 is installed at the upper end of the device housing 1, a reducer 105 is installed below the servo motor 102, and a stirring shaft 103 is installed at the lower end of the reducer 105. The stirring shaft 103 is fixedly connected to the distributing paddle 104 through a coupling. The stirring shaft 103 is driven by the servo motor 102 to drive the distributing paddle 104 to rotate, thereby driving the waste aluminum to rotate. During the rotation and heating process, the density difference between aluminum and impurities such as alumina is used to separate them.

[0027] It should be noted that a feeding tray 201 is installed at the lower end of the separation hopper 2. The feeding tray 201 is sealed to the separation hopper 2 through a flange. By disassembling and assembling the feeding tray 201, maintenance and cleaning work can be carried out inside the separation hopper 2 to achieve long-term operation.

[0028] It should be noted that both ends of the hydraulic cylinder 202 are movably connected to the connecting arm 303 and the unloading plate 201 respectively via connecting ears. A hydraulic pump is installed outside the device housing 1, and the hydraulic pump is connected to the hydraulic cylinder 202. The hydraulic cylinder 202 is adjusted by injecting hydraulic oil through the hydraulic pump.

[0029] Specifically, the servo motor 102 drives the stirring shaft 103 to rotate the dispensing paddle 104, which in turn rotates the waste aluminum. During the rotation and heating process, the aluminum is separated from impurities such as alumina by utilizing the density difference. The separated aluminum liquid is in the lower layer of the separation hopper 2. The alumina impurities in the upper layer are removed by opening the waste ash discharge port 203. During the feeding process of the separated aluminum liquid, the extension hydraulic cylinder 202 drives the lifting feeding column 3 to descend. After the lifting feeding column 3 descends, the aluminum liquid guide port 304 on the surface of the lifting feeding column 3 extends out of the feeding plate 201. The aluminum liquid enters the aluminum liquid guide port 304 through the gravity feeding port 305 for feeding.

[0030] An aluminum ash separation device for waste aluminum recycling in this embodiment includes a device housing 1. A separation hopper 2 for separating aluminum ash is provided below the device housing 1. A distributing paddle 104 is installed above the interior of the separation hopper 2. A lifting feed column 3 is installed at the bottom of the separation hopper 2. The waste aluminum to be separated is put into the feed inlet 101 and enters the separation hopper 2 for heating.

[0031] like Figure 1 and Figure 5As shown, the rear end of the separation hopper 2 is provided with a waste ash discharge port 203. The front and rear ends of the lifting feed column 3 are provided with inclined aluminum liquid guide ports 304. The upper end of the aluminum liquid guide port 304 is provided with a gravity feed port 305. The gravity feed port 305 is connected to the aluminum liquid guide port 304. The aluminum liquid enters the aluminum liquid guide port 304 through the gravity feed port 305 for feeding. The hydraulic cylinder 202 can extend and retract to effectively adjust the position of the aluminum liquid guide port 304, thereby adjusting the flow rate of the aluminum liquid to adapt to different tasks. The adjustment effect is good, the operation is convenient, and it is conducive to improving work efficiency.

[0032] Working principle: During use, the waste aluminum to be separated is placed into the feed inlet 101 and enters the separation hopper 2 for heating. The servo motor 102 drives the stirring shaft 103 to rotate the distributing paddle 104, causing the waste aluminum to rotate. During the rotation and heating process, the density difference between aluminum and impurities such as alumina is used for separation. The separated aluminum liquid is in the lower layer of the separation hopper 2. The alumina impurities in the upper layer are removed by opening the waste ash discharge port 203. During the feeding process of the separated aluminum liquid, the extension hydraulic cylinder 202 drives the lifting feed column 3 to descend. After descending, the aluminum liquid guide port 304 on the surface of the lifting feed column 3 extends out of the feed plate 201, and the aluminum liquid flows through... The molten aluminum enters the aluminum molten material guide port 304 through the gravity discharge port 305 for material guiding. Hydraulic oil is injected by the hydraulic pump to adjust the hydraulic cylinder 202 for adjustment. The hydraulic cylinder 202 extends and retracts, and the connecting head 301 is fixed by the connecting arm 303. The connecting head 301 and the connecting arm 303 are limited by the hydraulic cylinder 202 and move, driving the lifting discharge column 3 to rise and fall. This can effectively adjust the position of the aluminum molten material guide port 304, thereby adjusting the flow rate of the molten aluminum to achieve automated material feeding to adapt to different work. By disassembling and assembling the discharge plate 201, the inside of the separation hopper 2 can be maintained and cleaned to ensure long-term operation.
