Movable Hopper Disc Screen for Residue Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disc screens for solid material separation are limited by the need for continuous and uniform material flow, lack of operational versatility, and inability to adjust flow rates, leading to inefficient and costly screening processes, especially when handling varying residue dimensions and types.
Innovation Solution
A movable disc screen with a versatile design featuring a movable hopper and adjustable auger system, allowing for optimal loading and adjustable flow rates, enabling the separation of residues into two or three fractions and facilitating quick setup and relocation, with the ability to integrate with grinding or crushing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a continuous and uniform material flow is required for optimal screening operation, then screening efficiency is improved, but the system becomes less adaptable to varying material types and dimensions
Solution Approach 1:
The patent applies dynamics by making the hopper movable along the screening plane rather than fixed, allowing the system to adapt its feeding position dynamically. The hopper can be repositioned using a displacement system (hydraulic or mechanical) to optimize material distribution across different sections of the screening plane, thereby maintaining high screening efficiency while adapting to various material types and dimensions.
2Device complexity
If the screening plane length is fixed, then device structure is simplified, but the ability to adjust flow rate and handle different material dimensions is reduced
Solution Approach 1:
The hopper's movable design allows dynamic adjustment of the feeding position along the fixed screening plane. This enables the system to effectively handle different material dimensions and flow rates without changing the physical length or structure of the screening plane, maintaining structural simplicity while achieving operational flexibility.
3Productivity
If an external hopper is provided for creating continuous flow, then screening operation is improved, but installation time and cost increase
Solution Approach 1:
The patent merges the hopper function directly into the screening device by integrating a movable hopper that can be positioned along the screening plane. This eliminates the need for separate external hopper installations, reducing installation time and complexity while maintaining the capability to create continuous material flow for optimal screening operation.
4Device complexity
If the hopper is fixed in position, then device structure is simplified, but operational versatility and ability to handle different material dimensions are reduced
Solution Approach 1:
The movable hopper design provides dynamic positioning capability along the screening plane, enabling the system to adapt to different material dimensions and operational requirements. The hopper can be displaced to optimal positions for various material types while maintaining relatively simple overall device structure through the use of straightforward displacement mechanisms.
