Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining hydrostatic pressure in solid/liquid mixtures, such as in upflow columns during soil cleaning processes, are inaccurate and provide results too late, leading to potential clogging and inefficiencies in the cleaning process.
Innovation Solution
A device with a permeable housing and a liquid chamber connected to a pressure sensor, using a flushing liquid to accurately measure hydrostatic pressure by preventing solid penetration and adjusting flow rates to minimize blockage, allowing for precise determination of hydrostatic pressure and information about settled solid content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pressure sensor is directly immersed in the solid/liquid mixture to measure hydrostatic pressure, then measurement is possible, but solid particles penetrate and block the sensor causing inaccurate readings and potential clogging
Solution Approach 1:
The patent introduces a liquid chamber filled with flushing liquid as an intermediary medium between the solid/liquid mixture and the pressure sensor. The permeable housing allows liquid to pass through while blocking solid particles, thereby mediating the transmission of hydrostatic pressure to the sensor without allowing solids to contact and block the sensor directly.
Solution Approach 2:
The pressure sensor is enclosed in a housing with a permeable part that acts as a filter. This porous structure allows the flushing liquid to enter the liquid chamber and transmit pressure while preventing solid particles from penetrating into the chamber and blocking the sensor, thus maintaining measurement reliability.
2Reliability
If flushing liquid is introduced into the liquid chamber to prevent solid blockage, then solid penetration is reduced, but the device complexity increases due to additional components and flow control requirements
Solution Approach 1:
The flushing liquid system is designed to be self-regulating to the extent possible. The liquid chamber and permeable housing work together to automatically flush solids away from the sensor area using the flow of liquid through the permeable structure, reducing the need for complex external control mechanisms while maintaining reliability.
