In the process of high-temperature aluminum smelting, the high-temperature smelting furnace is one of the important equipment. In the process of using the high-temperature smelting furnace, the following steps are included: 1: adding aluminum raw materials, 2: smelting, 3: removing slag;

[0003] When melting aluminum by feeding solid aluminum, it is necessary to feed solid aluminum to a high-temperature melting furnace intermittently or continuously.

[0004] After searching, a Chinese patent (publication number: CN117983134B) disclosed CN117983134B, which includes: collecting concentration data of reactants, and then determining the corresponding concentration ratio data, taking the product of the concentration ratio data and the first preset adjustment value as the corresponding concentration adjustment data, and then determining the corresponding reaction intensity, and according to the preset reference minimum number of samples, obtaining the minimum number of samples of the reaction intensity; based on DBSCAN clustering, clustering is performed according to the preset neighborhood radius and the minimum number of samples, and then abnormal data is obtained, so as to control the delivery rate of auxiliary reactants.

[0005] In the prior art, solid aluminum is fed into a smelting furnace by workers to maintain the supply of raw materials required for production. However, there are many disadvantages, including low feeding accuracy, high labor intensity, and poor operating environment. Feeding solid aluminum into a smelting furnace through a transport device on a track or a fixed path requires a large space and has poor flexibility, which is not suitable for multi-point feeding requirements under complex working conditions. Therefore, the present invention proposes a trackless, self-propelled, solid aluminum intelligent feeding system and method for a high-temperature smelting furnace. Summary of the invention

[0163] A rotating frame 265 is installed inside the rotating material plate 263. The rotating frame 265 is used to load aluminum materials. When the aluminum materials are put in, the rotating frame 265 rotates to speed up the efficiency of putting in the aluminum materials.

After each positioning component 266 is started, its output end is embedded in the corresponding positioning groove. By locking the rotating part 268, the rotating material plate 263 is positioned and reinforced at the same time.

[0169] When feeding solid aluminum material, the second feeding vehicle 2 first drives to one side of the corresponding smelting furnace, then the feeding port of the smelting furnace is opened, the second driving unit 23 in the second feeding vehicle 2 is started, and the guide rail unit 24 is moved along the connecting groove in the smelting furnace, and then the third driving unit 25 is started, and the feeding unit 26 is slid along the guide rail unit 24 through the limit blocks 262 on both sides thereof, until the feeding unit 26 moves to the feeding area with the lowest solid aluminum content;

[0170] Then, each positioning assembly 266 is separated from the corresponding positioning groove in the rotating member 268, so that the rotating member 268 can rotate in the corresponding limit block 262, and then each second dumping unit 264 is started to rotate the rotating material plate 263 and the two sets of rotating members 268 and the corresponding limit block 262 as the center of the circle;

[0171] At the same time, the lifting cylinder in the blocking frame 267 is started to adjust the distance between the baffle member and the rotating frame 265. Finally, the rotating frame 265 is started to drop the solid aluminum material loaded on its upper side into the corresponding delivery area.
