[0002] With the rapid progress of the metallurgical industry, the mining and utilization of ore resources have reached an unprecedented speed and scale. This rapid development has led to a decrease in ore resources, and secondary ore resources have gradually been included in the vision of industrial production. However, the slag content in these secondary ores is relatively high, which undoubtedly increases the load on the slag handling system. Therefore, key equipment in the slag handling system, such as drum equipment, faces higher technical requirements.

[0003] In traditional slag handling systems, the drum conveyor usually adopts a combination of an internal walking belt conveyor and an external vertical belt conveyor to transfer the slag material. However, this traditional conveying device has several significant disadvantages. First, the device occupies a large area, which is not conducive to the effective use of space, especially in a space-limited environment such as a metallurgical plant. This problem is particularly prominent. Secondly, due to its complex mechanical structure and layout, the equipment is difficult to overhaul and maintain, which increases operating costs and downtime. Most importantly, this traditional conveying device is not ideal in terms of conveying efficiency and cannot meet the needs of modern high-efficiency and high-yield metallurgical production.

The hoisting frame can conveniently hoist and move the tilting belt conveyor, which is convenient for folding and unfolding. A walking mechanism 9 is provided between the rotating frame and the supporting frame. The walking mechanism can make the mobile belt conveyor move horizontally and be directly below the tilting belt conveyor to form a folded shape. The walking mechanism can drive the mobile belt conveyor to move horizontally to realize folding and unfolding with the tilting belt conveyor.

[0020] Furthermore, a tensioning device 8 is provided directly below the fixed section belt conveyor. The tensioning device can adjust the tension of the belt to ensure the normal operation of the belt conveyor and extend the service life of the belt. The tensioning device can be purchased externally and is a common auxiliary mechanism of the belt conveyor.

[0023] In at least one embodiment, the rotating frame includes a lower support column 61, and a left support rod 62 and a right support rod 63 are provided on the top of the lower support column.

[0028] After the inspection is completed, start the travel mechanism in reverse to slowly return the moving section of the belt conveyor to the inside of the drum along the track. At the same time, lower the height of the electric cylinder to return the tilting section of the belt conveyor to a position that is in line with the fixed section of the belt conveyor. After ensuring that all parts are reset and fixed, restart the drive motor of the belt conveyor and resume production.
