Technical Field
[0001] The utility model relates to the technical field of metal recovery, in particular to an aluminum ash roasting machine for aluminum alloy production. Background Art
[0002] The production process of aluminum slag and aluminum ash to aluminum ingots is that the aluminum melting furnace heats and melts the waste aluminum. The aluminum liquid at the bottom of the melting furnace enters the mold and cools into aluminum ingots. The slag formed during the smelting process of waste aluminum is aluminum ash. The aluminum ash still contains a large amount of aluminum, and the aluminum in the aluminum ash needs to be recovered through secondary treatment to improve economic benefits.
[0003] The traditional way is to stir-fry the high-temperature aluminum ash manually, which is not only time-consuming and labor-intensive, but also has certain safety hazards. At present, the processing workshop has introduced a highly automated ash stirrer. The aluminum ash enters the ash stirrer, which can further melt and separate the aluminum slag. The aluminum liquid enters the mold and is cooled into aluminum ingots. The high-temperature waste aluminum ash stirrered by the ash stirrer enters the cooler for cooling and packaging. However, the existing ash stirrer has the following problems: the aluminum ash attached to the surface of the stirring device needs to be manually cleaned regularly after long-term use, and the existing stirring device is always in the crucible and cannot be moved, which is inconvenient to clean. In addition, the ash stirrer is far away from the smelting furnace. After each slag removal, it must be transferred to the ash stirrer through the aluminum slag truck. The temperature of the aluminum slag is reduced, and the ash stirrer effect is not good. Utility Model Content

DETAILED DESCRIPTION
[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0022] Example: See Figure 1 - Figure 3 In this embodiment, it relates to an aluminum ash stirrer for aluminum alloy production, which is specifically used for automatic stir-frying and separation of aluminum ash, and specifically comprises: a machine body 1 and a stirring device 2, wherein a crucible 3 is arranged in the machine body 1, a bottom cover 4 is hinged at the bottom of the crucible 3, and a bottom hole 41 is arranged at the bottom cover 4, and the stirring device 2 is raised and lowered along the machine body 1 by a linear driving component 5.
[0023] Specifically, in this embodiment, the bottom cover 4 buckles the bottom of the crucible 3, and the tank for receiving the aluminum solution is placed under the machine body 1. The stirring device 2 is started, and the aluminum slag in a hot state (700 degrees to 750 degrees) after the slag removal treatment is put in. After all the aluminum slag is put in, it is stirred for a few minutes, and the aluminum liquid flows out of the bottom hole 41 until the aluminum liquid flows out in the form of drops, and the recovery is completed. The aluminum receiving tank is taken out, and the slag receiving tank is placed in the bottom of the machine body 1. Cold ash is added and stirred as needed to lower the temperature of the crucible 3. The bottom cover 4 is untied to let the aluminum slag fall into the ash receiving tank. The stirring device 2 stops, and the stirring device 2 is lifted by the linear drive component 5 to clean the aluminum ash attached to the stirring device 2 and the inside of the crucible 3. The utility model uses the linear drive component 5 to lift the stirring device 2 as a whole and keep it away from the crucible 3, so that the operator can clean the crucible 3 and the stirring device 2 easily. In addition, during the startup of the stirring device 2, the linear drive device can also drive the stirring device 2 to repeatedly rise and fall and oscillate. Through rotation and periodic stirring up and down, the aluminum ash in the crucible 3 can be more fully stirred, which helps to improve the recovery rate of the aluminum liquid.
[0024] Both sides of the machine body 1 are provided with a linear drive component 5, and the linear drive component 5 is a hydraulic cylinder 51, the cylinder body 511 of the hydraulic cylinder 51 is connected to the support plate 6 of the machine body 1, and the piston rod 512 of the hydraulic cylinder 51 is connected to the support arm 52, and the support arm 52 is slidably connected to both ends of the machine body 1, and one end is fixedly connected to the stirring device 2. Figure 4The support arm 52 is provided with a guide groove 521, and the side of the machine body 1 is provided with a guide bar 11 that is slidably matched with the guide groove 521. The utility model adopts a hydraulic cylinder 51 as the linear driving component 5, and drives the support arm 52 to move along the vertical direction of the machine body 1 through the hydraulic cylinder 51, thereby realizing the lifting and lowering of the stirring device 2, and through the design of the support arm 52 and the guide groove 521, the stirring device 2 remains stable during the lifting process.
[0025] The stirring device 2 comprises a stirring shaft 21 and a plurality of stirring blades 22 . The stirring shaft 21 is driven to rotate by a motor 23 via a transmission mechanism 24 , and the stirring blades are fixed on the stirring shaft 21 .
[0026] See also Figure 5 The transmission mechanism 24 adopts chain transmission, including a first sprocket 241 fixed on the shaft of the motor 23, a second sprocket 242 fixed on the stirring shaft 21, and a chain 243. The two ends of the chain 243 are respectively sleeved and meshed with the first sprocket 241 and the second sprocket 242, wherein the outer diameter of the first sprocket 241 is smaller than that of the second sprocket 242, thereby achieving a deceleration effect.
[0027] Two support plates 6 are symmetrically arranged at the bottom of the machine body 1, and moving wheels 7 are installed under the two support plates 6 to facilitate the movement of the machine body 1 to the vicinity of the smelting furnace and shorten the distance between the two. This solves the problem in the prior art that the ash roasting machine is far away from the smelting furnace, resulting in a decrease in the temperature of the aluminum slag and affecting the ash roasting effect.
[0028] See also Figure 6 , a baffle 12 is provided on one side of the hydraulic cylinder 51, the side of the baffle 12 is fixed on the machine body 1, the lower end of the baffle 12 is fixed on the support plate 6, and a notch 121 is provided at the lower end of the baffle 12, and the notch 121 is plugged and adapted with the folded edge 61 of the support plate 6. The design of the baffle 12 can effectively prevent the splash of aluminum ash during stirring from causing damage to the hydraulic cylinder 51, and play a protective role. At the same time, a complete force system is formed between the support plate 6 and the machine body 1, which effectively disperses and transmits the force generated by the hydraulic cylinder 51 during the working process, so that the force of the hydraulic cylinder 51 is more uniform, and the supporting strength and durability of the overall equipment are improved.
[0029] The transmission mechanism 24 is adapted to be equipped with a cover 25, one end of which is fixed to the support arm 52, and the other end is fixed to the housing of the motor 23, thereby ensuring the connection stability of the cover 25. The cover 25 covers the transmission mechanism 24, preventing dust, aluminum ash, debris, etc. from entering the transmission components (the first sprocket 241, the second sprocket 242, and the chain 243, etc.), reducing the possibility of wear and damage to the transmission components, and extending the service life of the transmission mechanism 24. In addition, the cover 25 can also prevent the operator from accidentally contacting the moving parts of the transmission mechanism 24 during work, avoiding the risk of injury caused by high-speed rotating components, and ensuring the safety of operation.
