Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grain handling equipment faces issues with plugging due to oversized materials and requires significant time and effort for maintenance and replacement, especially when dealing with variable flow rates and wear-related damage.
Innovation Solution
An angle adjustable system with a baffle-less input spout sleeve and removable wear pads, allowing for efficient deceleration of dry bulk materials without internal baffles, reducing the frequency of plugging and maintenance time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjustable spout ends with internal baffles are used, then material flow direction can be controlled, but the system becomes prone to plugging by oversized materials and requires frequent maintenance
Solution Approach 1:
The patent removes the internal baffles from the spout end design, extracting the problematic element that caused plugging. The flow direction control is achieved through the external adjustable spout end structure rather than internal baffles, eliminating the source of plugging while maintaining operational control.
Solution Approach 2:
The spout end is divided into separable components including removable wear pads that can be accessed through an access door. This segmentation allows easy replacement of wear components without removing the entire spout end assembly, reducing maintenance time and improving reliability.
2Productivity
If traditional adjustable spout ends are used, then material delivery can be achieved, but considerable time and effort are required for replacement when wear damage occurs
Solution Approach 1:
The spout end is segmented into modular components with removable wear pads that can be independently replaced. An access door provides easy access to these components, allowing quick maintenance without shutting down the entire material delivery system for extended periods.
Solution Approach 2:
The wear pads are designed as replaceable components that can be pre-maintained or replaced before failure occurs. The access door and modular design enable preliminary maintenance actions that prevent complete system failure and minimize downtime.
3Duration of action of stationary object
If adjustable spout ends are designed for wear resistance, then durability is improved, but the complexity of the device increases with more components
Solution Approach 1:
Instead of making the entire spout end complex and heavy-duty, the wear pads are applied locally to specific high-wear areas. This localized approach provides durability where needed while keeping the rest of the spout end design simple and straightforward.
Solution Approach 2:
The wear pads are designed as sacrificial, replaceable components that can be easily replaced when worn. This approach accepts that these specific components will have limited service life but minimizes the overall system complexity and cost compared to making the entire spout end fully replaceable and complex.
