Description
Technical Field
[0001] This utility model relates to the field of aluminum production technology, specifically to an aluminum liquid ash-frying system. Background Technology
[0002] Aluminum ash frying machine is a commonly used piece of equipment in the aluminum processing industry. It includes an ash frying pot and a stirring mechanism mounted on the pot. The stirring mechanism separates the molten aluminum from the filter residue, and the molten aluminum is discharged through the outlet of the pot. In existing ash frying machines, some fine aluminum slag leaves the molten aluminum or the pot under centrifugal force and becomes aluminum ash. If the aluminum ash is not treated, it will mix back into the molten aluminum. In addition, during the stirring process, heat is lost from the molten aluminum, causing the temperature of some of the molten aluminum in the pot to drop. If the temperature drops too low, surface condensation will occur, which seriously affects the normal escape of ash. Therefore, a complete system is needed to systematically perform the aluminum ash frying operation. This invention provides an aluminum molten aluminum ash frying system. Utility Model Content

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0025] A slag frying machine is a commonly used piece of equipment in the aluminum processing industry. It includes a slag frying pot 4 and a stirring mechanism 11 mounted on the slag frying pot 4. The stirring mechanism 11 is used to stir and separate the molten aluminum from the filter residue, and the molten aluminum is discharged through the outlet of the slag frying pot 4. In existing slag frying machines, some fine aluminum slag leaves the molten aluminum or the slag frying pot 4 under centrifugal force and becomes aluminum ash. If the aluminum ash is not treated, it will mix back into the molten aluminum. In addition, during the stirring process, heat is lost from the molten aluminum, causing the temperature of some of the molten aluminum in the slag frying pot 4 to drop. If the temperature is too low, surface condensation will occur, which seriously affects the normal escape of ash. Therefore, a complete system is needed to systematically perform the slag frying operation for molten aluminum. Therefore, this utility model provides an aluminum molten aluminum slag frying system.
[0026] This utility model provides an aluminum molten metal ash-frying system, such as... Figure 1As shown, the device includes a ash-making box 1 and an aluminum ash collection assembly. The aluminum ash collection assembly is used to process and classify the aluminum ash raised in the ash-making box 1. The aluminum ash collection assembly includes a pretreatment mechanism 2 and an ash collection mechanism. The ash-making box 1 includes an outer cover, a stirring mechanism 11 located at the upper end of the outer cover, a feed inlet 12 located at the lower end of the outer cover, and the pretreatment mechanism 2 used to connect with the ash-making box 1. The inner side wall of the feed inlet 12 at the lower end of the outer cover is provided with two parallel supports 121, which are used to support the ash-making pot 4. The pretreatment mechanism 2 includes a temperature control box 21, an electrical control box 22, and a filter box 23. The temperature control box 21 is located at the right end of the ash-making box 1, and the filter box 23 is located at the right end of the temperature control box 21. The electrical control box 22 is a control equipment mounting box used to fix the control circuit or control equipment. The ash collection mechanism includes a collection pipe 3 for docking with the ash-frying box 1 and the pretreatment mechanism 2, a coarse ash bin 5 and a fine ash bin 6 for docking with the collection pipe 3.
[0027] As described above, the aluminum molten metal ash-frying system provided by this utility model includes an ash-frying box 1 and an aluminum ash collection assembly for completing the ash frying and aluminum ash collection. The upper space of the ash-frying box 1 is equipped with a stirring mechanism 11, and the lower space is used to hold an ash-frying pot 4, which is configured to enter and exit through the feed inlet 12 at the lower end of the outer cover of the ash-frying box 1. A temperature control box 21 is located next to the ash-frying box 1 to adjust the temperature during the ash-frying process. Specifically, auxiliary heating can be set around the ash-frying pot 4 using electrolytic heating to maintain a stable temperature within the pot 4, while reducing heat conduction to minimize temperature loss within the ash-frying box 1. A filter box 23 is located next to the temperature control box to filter large splashed aluminum ash particles to the bottom of the filter box 23. Fine aluminum ash is collected through a collection pipe 3, passing through a coarse ash bin 5 and a fine ash bin 6 respectively, settling into different collection bags. The system achieves automatic ash frying and automatic classification and collection of aluminum ash of different specifications. At the same time, the temperature control box 21 flexibly adjusts the temperature in the ash frying box 1 to avoid uneven temperature of the aluminum liquid in the ash frying pot 4. In addition, the filter box 23 and the coarse ash bin 5 and fine ash bin 6 work together to classify and collect aluminum ash of different particle sizes, realizing systematic ash frying and improving the practicality of the ash frying system.
[0028] The present invention will now be described in detail with reference to the accompanying drawings.
[0029] like Figure 2As shown, the aforementioned stirring mechanism 11 includes a connecting shaft, a main stirring part 111 connected to the end of the connecting shaft, a connecting rod 112 connected to the connecting shaft, a secondary stirring part 113 connected to the connecting rod 112, and an umbrella-shaped heat insulation cover 114 connected to the upper end of the connecting shaft. The secondary stirring part 113 includes a connecting block, a fixing pin, and a stirring block. The stirring block is connected to the connecting block by the fixing pin, and the connecting block includes multiple pin holes at different angles.
[0030] In this embodiment, a main stirring unit 111 and a secondary stirring unit 113 are configured to work together to stir the molten aluminum in the ash-frying pot 4. The main stirring unit 111 and the secondary stirring unit 113 are used to stir the molten aluminum at different diameters within the pot body 41, so that the molten aluminum at various locations within the pot body 41 can be stirred simultaneously. The fixing pin in the secondary stirring unit 113 fixes the position of the stirring block, which allows for easy adjustment of the stirring block's position and improves the practicality of the stirring mechanism 11. At the same time, the umbrella-shaped heat insulation cover 114 not only reduces the loss of temperature of the molten aluminum during stirring but also prevents the molten aluminum from splashing during stirring.
[0031] It is feasible to arrange the aforementioned secondary stirring unit 113 and the stirring center of the main stirring unit 111 to be parallel to each other or intersect at an acute angle. When they are parallel, their stirring tools are perpendicular to the surface of the ash-frying pot 4. When they intersect at an acute angle, the stirring tool of the main stirring unit 111 is perpendicular to the surface of the ash-frying pot 4, and the stirring tool of the secondary stirring unit 113 forms an acute angle with the surface of the ash-frying pot 4. This achieves the purpose of turning the molten aluminum over during rotation, thereby improving the stirring effect.
[0032] Additionally, in this embodiment, as Figure 3 As shown, the ash-frying pot 4 includes a pot body 41 and a pair of supporting tubes 42 connected to the bottom surface of the pot body 41. The tubes of the supporting tubes 42 are hollow. The pot body 41 includes a pot rim at the top of the pot body 41 and a fixing rib 43 on the outer side of the pot body 41. The horizontal bottom surface of the fixing rib 43 is connected to the top surface of the supporting tubes 42.
[0033] In this embodiment, a hollow support tube 42 is provided at the bottom of the ash-frying pot 4 to facilitate insertion by a forklift. After insertion, the ash-frying pot 4 is placed into or removed from the ash-frying box 1. The pot rim on top of the pot body 41 is used to contact the parallel support 121 at the bottom of the ash-frying box 1, that is, the parallel support is used to stably support the ash-frying pot 4. The fixing ribs 43 on the pot body 41 are used to stabilize the structure of the pot body 41, increase the stability of the connection between the bottom surface of the pot body 41 and the support tube 42, and prevent the pot body 41 from shaking during the stirring process.
[0034] In some embodiments, such as Figure 4As shown, the stirring blocks of the aforementioned main stirring section 111 and auxiliary stirring section 113 are both arc-shaped structures, and the arc radii of the stirring blocks of the main stirring section 111 and the auxiliary stirring section 113 are equal. With this structure, the rotational speed of the aluminum ash in the molten aluminum at different locations is equal during the stirring process, effectively controlling the splashing of aluminum ash due to changes in rotational speed.
[0035] In some embodiments, both the stirring blocks of the main stirring section 111 and the stirring blocks of the auxiliary stirring section 113 are fitted with blades made of manganese steel. These blades serve to protect the main body of the stirring block from being melted or corroded by the high-temperature molten aluminum, thereby increasing the service life of the stirring block.
[0036] Finally, this utility model provides an aluminum molten metal ash-making system, including an ash-making box 1 and an aluminum ash collection assembly. The aluminum ash collection assembly is used to process and classify the aluminum ash raised in the ash-making box 1. The aluminum ash collection assembly includes a pretreatment mechanism 2 and an ash collection mechanism. The ash-making box 1 includes an outer cover, a stirring mechanism 11 located at the upper end of the outer cover, a feed inlet 12 located at the lower end of the outer cover, and a pretreatment mechanism 2 used to connect with the ash-making box 1. The inner side wall of the feed inlet 12 at the lower end of the outer cover is provided with two parallel supports 121, which are used to support the ash-making pot 4. The pretreatment mechanism 2 includes a temperature control box 21, an electrical control box 22, and a filter box 23. The temperature control box 21 is located at the right end of the ash-making box 1, and the filter box 23 is located at the right end of the temperature control box 21. The ash collection mechanism includes a collection pipe 3 used to connect with the ash-making box 1 and the pretreatment mechanism 2, a coarse ash bin 5 used to connect with the collection pipe 3, and a fine ash bin 6. This invention enables automatic ash removal and automatic grading and storage of aluminum ash, thereby improving the overall practicality of the ash removal system.
[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
