Rotating-drum method based full flow processing system and rotating-drum method based full flow processing technique

Abstract

The invention discloses a rotating-drum method based full flow processing system and a rotating-drum method based full flow processing technique. The system mainly comprises a tipping device, a slagging-off device, a rotating drum device, a finished-product conveying device, a vibratory separation device, a bucket-type lifting device, an online magnetic separation device, a storage device, a dust removal device, a water system device and an electrical control device. The tipping device and the slagging-off device are used for assisted feeding. The rotating drum device is used for core processing of steel slags. The rotating-drum method based full flow processing system and the rotating-drum method based full flow processing technique have the advantages that rotating-drum processing rate of the steel slags can be increased remarkably, slag feeding safety and reliability of a rotating drum can be improved, and travelling crane occupancy rate can be reduced; the steel slags processed by the rotating drum can be subjected to online separation and initial magnetic separation; materials can be stored in a overhead bunker, and environmental pollution and surplus input both caused by secondary and multiple loading and unloading of finished slags are avoided.

Description

technical field [0001] The invention relates to a molten liquid steel slag treatment system and process, in particular to a full-process treatment system and process for molten liquid steel slag treatment by a drum method. Background technique [0002] The drum method slag treatment device is one of the most advanced molten liquid slag treatment devices in the world. It has the characteristics of short process, high efficiency, cleanliness, safety and reliability. [0003] However, the existing technology for slag treatment using the drum method slag treatment device has the following disadvantages: [0004] (1) When using this device to process steel slag, the existing slag feeding method is mainly carried out by manual operation, which not only occupies limited driving resources, but also makes it difficult to ensure the efficiency and quality of slag feeding, and cannot effectively improve safety; [0005] (2) Due to the characteristics of the steelmaking process, high...

AI Technical Summary

Problems solved by technology

[0004] (1) When using this device to process steel slag, the existing slag feeding method is mainly carried out by manual operation, which not only occupies limited driving resources, but also makes it difficult to ensure the efficiency and quality of slag feeding, and cannot effectively improve safety;

[0005] (2) Due to the characteristics of the steelmaking process, highly viscous steel slag is becoming more and more common, and it is impossible to control the uniform slag feeding by operating the crane, which seriously restricts the processing efficiency of the drum slag processing device;

[0006] (3) The original processed steel slag is directly dropped into the slag yard through the conveyor, and then re-transported by forklifts and trucks. Repeated re-transportation brings pollution to the environment, the overall environment cannot be completely improved, and it also increases operations. cost
