Innovation Solution
A pneumatic conveying system comprising a power unit, fan unit, valve unit, pneumatic conveying unit, and pipeline arrangement network, along with a control method that allows for rapid switching between single-fan suction/pressure modes, series/parallel connection modes of multiple fans, and adaptive control of blast volume and pressure to match operational requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed air source device is selected and designed, then the system structure is simple and cost is low, but the conveying distance and conveying rate cannot be significantly adjusted
Solution Approach 1:
The patent implements dynamic adjustment capabilities by enabling the air source device to switch between different operating modes (suction and pressure), adjust blast volume and blast pressure, and change conveying distance and rate. This dynamic flexibility allows the system to adapt to different operational requirements without requiring multiple fixed systems, thus improving adaptability while managing complexity through a single versatile platform.
Solution Approach 2:
The air source device is designed with multi-functionality, capable of performing both suction-type and compression-type pneumatic conveying operations. It can adjust between different blast volumes and pressures, and switch between suction and pressure modes, making a single device serve multiple functions and operational requirements, thereby enhancing adaptability without proportionally increasing system complexity.
2Adaptability or versatility
If the air source device is fixed immediately after design, then the system is stable and easy to operate, but it cannot rapidly adjust blast volume, blast pressure, or switch modes to adapt to different conditions
Solution Approach 1:
The system incorporates dynamic control mechanisms that allow rapid adjustment of blast volume and blast pressure, as well as switching between suction and pressure modes. These dynamic features enable the air source device to quickly adapt to different operational conditions while maintaining a unified control interface that preserves operational simplicity.
Solution Approach 2:
The patent enables rapid adjustment of key parameters including blast volume, blast pressure, and operational mode (suction/pressure). By allowing these parameters to be changed dynamically during operation, the system achieves high adaptability to different conveying requirements while maintaining ease of operation through controlled parameter modification rather than complex system reconfiguration.
3Productivity
If a single fan is used in the pneumatic conveying system, then the device complexity is low, but the conveying capacity and pressure are limited
Solution Approach 1:
The patent implements a fan configuration system that can combine multiple fans into series or parallel connections to achieve higher conveying capacity and pressure. The control system coordinates multiple fans working together, merging their capabilities to surpass the limits of a single fan while managing the complexity through integrated control and coordination mechanisms.
Solution Approach 2:
The system provides dynamic flexibility in fan configuration, allowing switches between single-fan mode, series connection mode, and parallel connection mode. This dynamic reconfiguration capability enables the system to optimize conveying capacity and pressure according to operational requirements, achieving high productivity when needed while maintaining simplicity through flexible, on-demand configuration.
