Hybrid Fan Pump Suction System for Pneumatic Conveying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction systems either excel in thick-flow conveying with high pressure but low volume flow, or in thin-flow conveying with low pressure and high volume flow, but not efficiently in both modes, and require excessive drive power for differential pressure increase.
Innovation Solution
A suction system combining fan and pump systems in series or parallel configurations within a common suction flow line, integrated with a separator and filter, allowing for adjustable volume flow and pressure difference, and featuring a shut-off system to prevent counter-directional suction, and a safety system to manage vacuum levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If pump systems are used to generate high differential pressure, then thick-flow conveyance is enabled, but volume flow remains comparatively low
Solution Approach 1:
The patent combines a fan system and a pump system in a hybrid suction system. The fan system generates high volume flow while the pump system provides the necessary differential pressure. Both systems operate simultaneously on the same suction line, merging their capabilities to achieve both high pressure and high volume flow that neither system could achieve alone.
2Quantity of substance
If fan systems are used to generate large air flows, then volume flow is increased, but differential pressure remains comparatively low
Solution Approach 1:
The hybrid suction system merges the high volume flow capability of the fan system with the high differential pressure capability of the pump system. The fan creates the bulk air flow necessary for lean phase conveying, while the pump provides the additional pressure head required for efficient material transport.
3Stress or pressure
If two or more fans are connected in series to increase differential pressure, then differential pressure is increased, but drive power increases quadratically
Solution Approach 1:
Instead of connecting multiple fans in series which would require quadratic increases in drive power, the patent combines a single fan system with a single pump system. The pump handles the pressure generation efficiently without the exponential power increase, while the fan maintains high volume flow capability.
4Adaptability or versatility
If a hybrid fan-pump system is used for both thick and thin flow conveyance, then versatility is improved, but device complexity increases
Solution Approach 1:
The patent integrates a fan system and pump system into a unified suction system with a common suction line and separator. This merging approach provides versatility for both thick and thin flow conveyance while maintaining a relatively simple overall structure through shared components.
Solution Approach 2:
The hybrid system is designed to perform multiple functions: it can handle both thick-flow and thin-flow conveyance, adapt to different material types, and operate in various suction scenarios. The fan and pump work together to provide universal capability across different conveying requirements.
