Switchable Discharge Conveyor for Multi-Deck Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screening technologies are limited in their ability to efficiently separate mixed materials into three graded streams, particularly in variable applications or where space and noise are constraints, such as in waste processing facilities.
Innovation Solution
A mobile multi-deck screening apparatus with overlapping decks and switchable discharge conveyors, allowing operation as either a two-way-split or three-way-split, where one discharge conveyor can switch between active and inactive states to discharge one or two graded streams, enabling flexible fraction separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed multi-deck screening apparatus is used to separate materials into three graded streams, then the separation capability is improved, but the device complexity and space requirement increase
Solution Approach 1:
The patent applies the dynamics principle by making the discharge conveyor switchable between active and inactive states. The conveyor can be dynamically reconfigured to discharge either one graded stream (when active) or two graded streams (when inactive), allowing the same apparatus to adapt between different separation modes without requiring multiple fixed machines.
Solution Approach 2:
The patent implements universality by designing a single multi-deck screening apparatus that can perform multiple functions: it can operate as a three-way-split when the switchable conveyor is active, and as a two-way-split when the conveyor is inactive. This multi-functional design eliminates the need for separate dedicated machines for different separation requirements.
2Adaptability or versatility
If multiple fixed screening machines are used to handle variable applications, then the separation flexibility is improved, but the noise and space consumption increase
Solution Approach 1:
The patent merges the functionality of multiple fixed screening machines into a single integrated apparatus. By combining multiple decks and a switchable discharge conveyor system, the apparatus can handle variable applications that would otherwise require separate machines, thereby reducing overall noise levels and space requirements while maintaining separation flexibility.
3Adaptability or versatility
If multiple fixed screening machines are deployed for different fraction separations, then the separation precision is improved, but the space requirement increases
Solution Approach 1:
The patent uses dynamics by implementing a switchable discharge conveyor that can be reconfigured between active and inactive states. This dynamic reconfiguration allows the same physical space to serve different separation purposes: when the conveyor is active, it discharges one graded stream with high precision; when inactive, it combines to discharge two graded streams, all within a compact footprint.

AI summary
The present invention provides a mobile multi-deck screening apparatus for screening a mixed material into three graded streams, the apparatus comprising two or more overlapping screening decks and at least three discharge conveyors, wherein one discharge conveyor is a switchable conveyor selectively switchable between an active state such that each discharge conveyor discharges one graded stream, to an inactive state such that one discharge conveyor discharges two graded streams.
