Description

Technical Field

[0001] The utility model belongs to the technical field of copper smelting, and particularly relates to a waste copper preheating device based on the residual heat of copper smelting fume. Background Art

[0002] Copper smelting refers to the process of extracting copper from ore or scrap copper. There are two methods of copper smelting, namely pyrometallurgy and hydrometallurgy. Pyrometallurgy produces a large amount of flue gas, which contains not only various harmful substances but also a large amount of waste heat. In order to reduce energy loss, the treated flue gas is usually introduced into a preheating device to preheat the ore or scrap copper.

[0003] The existing document with announcement number CN218687524U discloses a raw material preheating device for copper purification, comprising a preheating box, a sealing door panel is provided on the front of the preheating box, an operating handle is fixedly installed on the front of the sealing door panel, a ventilation filter device is fixedly installed on the bottom of the left and right sides of the preheating box, and a stabilizing ring is fixedly installed on the inner wall of the bottom of the preheating box;

[0004] However, it still has the following disadvantages in actual use:

[0005] The above-mentioned preheating device has ventilation and filtering devices fixedly installed at the bottom of the left and right sides of the preheating box, a stabilizing ring fixedly installed on the inner wall of the bottom of the preheating box, a driving motor fixedly installed on the inner wall of the bottom of the preheating box, and a preheating disc that rotates with the upper surface of the stabilizing ring fixedly installed on the output end of the driving motor. Scrap copper and other raw materials are placed in the preheating disc, and the preheating disc is driven by the driving motor to rotate, thereby cooperating with the setting of the heating disc to realize preheating of scrap copper and other raw materials. However, during use, it lacks a structure for cleaning scrap copper and other raw materials, and dust, oil and other impurities will adhere to the surface of scrap copper and other raw materials. The presence of these impurities will affect the subsequent smelting effect;

[0006] The above-mentioned preheating device has ventilation and filtering devices fixedly installed at the bottom of the left and right sides of the heat box, a stabilizing ring fixedly installed on the inner wall of the bottom of the preheating box, a driving motor fixedly installed on the inner wall of the bottom of the preheating box, and a preheating disc rotating relative to the upper surface of the stabilizing ring fixedly installed on the output end of the driving motor. Scrap copper and other raw materials are placed in the preheating disc, and the preheating disc is driven to rotate by the driving motor, thereby preheating the scrap copper and other raw materials is achieved in conjunction with the setting of the heating disc. However, during use, it lacks a structure for cutting and crushing the scrap copper and other raw materials, which affects the preheating efficiency due to the large volume of the scrap copper and other raw materials.

[0007] To this end, we provide a scrap copper preheating device based on the waste heat of copper smelting flue gas to solve the above problems. Utility Model Content
