Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary drum processes are inefficient in handling steel slag with high viscosity or solid slag, particularly large pieces at the bottom of the tank, leading to low processing efficiency and safety hazards due to accumulation and manual operation errors.
Innovation Solution
A rotary drum processing method with a tilting mechanism and a storage bin positioned between the drum and feeding chute, allowing for controlled feeding and continuous operation, combined with mechanical cleaning, to process all types of steel slag efficiently and safely, including high fluidity, viscous, and solid slag without fluidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rotary drum process is used to process high fluidity steel slag, then processing can be performed, but it cannot process viscous or solid steel slag efficiently
Solution Approach 1:
The rotary drum is designed with adjustable rotation speed and tilt angle, allowing it to adapt to different types of steel slag (high fluidity, viscous, or solid). The dynamic adjustment of operational parameters enables the single equipment to process all slag types efficiently without requiring multiple specialized devices.
2Adaptability or versatility
If slag tank tilting mechanism and slag scraper are used to feed viscous solid steel slag into rotary drum, then some slag can be processed, but feeding efficiency is low and processing period is long
Solution Approach 1:
The slag tank is tilted to a predetermined angle before slag feeding begins, pre-positioning the viscous or solid slag for optimal flow into the rotary drum. This preliminary positioning action ensures that slag feeds continuously and efficiently without requiring repeated adjustments or manual intervention during the processing period.
Solution Approach 2:
The system maintains continuous slag feeding by coordinating the tilt mechanism and rotary drum operation to ensure uninterrupted flow. The drum rotates continuously while the tilt mechanism adjusts as needed, eliminating idle time and maintaining constant processing action throughout the slag treatment cycle.
3Ease of operation
If large-sized slag at the bottom of the tank is poured onto the ground or flowed backwards, then handling is simplified, but processing efficiency is reduced
Solution Approach 1:
The rotary drum system is designed to universally handle all types of steel slag including large-sized slag at the bottom of the tank. The drum's rotation and crushing mechanism automatically process these difficult-to-handle materials, eliminating the need for separate handling procedures like pouring onto ground or flowing backwards, while maintaining high processing efficiency.
4Speed
If mechanical turning over, spraying cooling water is performed to improve cooling efficiency, then cooling rate increases, but dust diffusion and explosion risk increase
Solution Approach 1:
The rotary drum processing creates a controlled environment where slag is continuously moved and cooled through mechanical action rather than open-air water spraying. This enclosed processing method reduces dust diffusion into the surrounding environment and minimizes explosion risks while maintaining effective cooling rates through the drum's rotation and internal cooling mechanisms.
