Bidirectional Conveyor Discharge for Horizontal Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional horizontal filtration equipment requires separate doors or rotating plates to manage solid and liquid discharge, which occupy space, increase safety risks, and cause conveyor wear due to dropping solids from height.
Innovation Solution
A dual-action conveyor system that allows simultaneous discharge of solids and liquids on the same conveyor during different phases, eliminating the need for movable doors or plates and integrating the functionality of a dispatch hatch into the conveyor design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate doors or rotating plates are used to prevent liquids from ending up on the conveyor, then liquid containment is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent removes the separate door or rotating plate mechanism from the system entirely. Instead, the conveyor belt itself performs the liquid containment function by being positioned below the filter apparatus and receiving both solids and liquids during different phases of the work cycle, eliminating the need for additional protective components.
Solution Approach 2:
The conveyor belt is designed to perform multiple functions: it conveys solids during the discharge phase and receives liquids during the filtration phase. This multi-functional design replaces the need for separate doors or plates, simplifying the overall system while maintaining liquid containment effectiveness.
2Reliability
If doors or rotating plates are installed between filter apparatus and conveyor, then liquid protection is improved, but space requirements and safety risks worsen
Solution Approach 1:
The patent eliminates movable doors or rotating plates from the system. The conveyor belt is positioned to receive materials directly from the filter apparatus without intermediate protective structures, removing the safety hazards associated with moving parts near ground level while maintaining liquid protection through proper positioning and timing.
3Productivity
If solids are dropped from height on conveyor, then discharge function is achieved, but conveyor wear increases
Solution Approach 1:
The conveyor belt is positioned at the same level as the discharge point of the filter apparatus. During the discharge phase, solids are deposited onto the conveyor belt with minimal height difference, reducing impact forces and wear on the conveyor while maintaining effective discharge functionality.
4Reliability
If movable doors or plates are used for discharge, then solid-liquid separation is improved, but device complexity and maintenance needs increase
Solution Approach 1:
The patent removes movable doors or rotating plates from the system. Solid-liquid separation is achieved through the timing and positioning of the conveyor belt, which receives solids during discharge and liquids during filtration without requiring intermediate protective structures that would need maintenance.
Solution Approach 2:
The conveyor belt performs both solid conveyance and liquid reception functions, eliminating the need for separate doors or plates. This simplifies the system structure and reduces maintenance requirements while maintaining effective solid-liquid separation through operational timing.

AI summary
A discharge arrangement for horizontal filtration equipment. The discharge arrangement includes a conveyor configured to be provided below the horizontal filtration equipment for receiving discharge material discharged from the horizontal filtration equipment, and a drive for driving the conveyor. The drive is configured to enable driving the conveyor in two opposite directions. Thereby, material provided on the conveyor can be discharged at either a first end or a second end depending on the direction in which the conveyor is driven.
