Compact Spray and Suction Unit for Cold Rolling Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for applying and removing operating fluids in cold rolling systems are bulky and expensive due to their complex construction, lacking a compact and efficient solution for both application and suction removal.
Innovation Solution
A compact apparatus combining a spray device and a suction removal device attached to a common frame, allowing for direct application and suction of operating fluids onto rolling stock or working rolls, with the suction device positioned to efficiently remove fluid particles or mist, and featuring a multi-substance nozzle and mist suction removal system for air treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large-volume housing with hollow wall parts and suction conduits is used for fluid removal, then fluid removal effectiveness is improved, but construction volume and cost increase
Solution Approach 1:
The spray device and suction removal device are merged into a single integrated unit that is directly mounted on the rolling stock. This eliminates the need for a separate large-volume housing while maintaining effective fluid removal through the combined action of spraying and immediate suction at the source.
Solution Approach 2:
The system is segmented into a compact modular unit that can be directly attached to the rolling stock, separating the fluid application and removal function from the overall system housing. This allows the suction function to be localized without requiring a large enclosing structure.
2Reliability
If a large-volume housing with suction conduits is used, then fluid removal effectiveness is improved, but construction complexity and cost increase
Solution Approach 1:
The spray device and suction removal device are combined into one integrated compact unit, reducing construction complexity by eliminating the need for separate housing, multiple suction conduits, and complex mounting structures while maintaining effective fluid removal.
Solution Approach 2:
The integrated unit is directly mounted on the rolling stock and serves itself by positioning the suction opening in direct proximity to the spray device, eliminating the need for complex external housing and conduit systems.
3Adaptability or versatility
If spray device and suction device are separated, then installation flexibility is improved, but space efficiency and cost decrease
Solution Approach 1:
The spray device and suction removal device are merged into a single compact unit that maintains installation flexibility through direct mounting on the rolling stock while improving space efficiency by eliminating the need for separate housing and conduit routing.
