Description

Technical Field

[0001] The utility model belongs to the technical field of waste recycling, and more specifically, relates to a screening device for copper smelting from lead matte slag. Background Technique

[0002] Copper smelting slag contains various valuable metals such as tin, copper, lead, zinc, and iron, and its potential utilization value is relatively high. However, due to its complex composition and relatively low grade, it is difficult to extract the metals from it, resulting in a large amount of secondary resource waste.

[0003] For example, a recovery system for copper smelting dust removal slag with the patent application number CN202222523523.7 includes a support frame. A recovery box is fixedly connected to the support frame. A feed inlet is arranged at the top of the recovery box. Hydraulic cylinders are symmetrically arranged on both sides at the top end of the recovery box. The output end of the hydraulic cylinder passes through the recovery box and is connected to a mounting frame. A first motor is arranged on one side of the mounting frame. A crushing roller is arranged on the mounting frame. A diversion frame is arranged below the mounting frame. A screening frame is arranged below the diversion frame. A second motor is installed at the bottom of the diversion frame. An anti-blocking stirring rod is arranged on the output shaft of the second motor. The two ends of the screening frame are slidably connected in the recovery box. A protective housing is arranged below the screening frame. By providing a crushing roller, when recovering the slag, the mounting frame is driven by the hydraulic cylinder to move, and the distance between the two crushing rollers on both sides is adjusted, so that the size of the crushed slag can be adjusted, which is convenient for screening the slag.

[0004] Although the above-mentioned recovery system for copper smelting dust removal slag can adjust the size of the crushed slag, the screening efficiency is not high. Summary of the Utility Model
