Turbidimeter Sample Cell Cleaning With Wipers and Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional turbidimeters face issues with particulate buildup in sample cells, leading to inaccurate turbidity measurements due to residual particulate matter obstructing light paths and interfering with measurement accuracy.
Innovation Solution
A cleaning device with wipers, brushes, and a suction tube is introduced into the sample cell to mechanically dislodge and remove particulates, utilizing a secondary flow path for cleaning, which can be automated based on system-determined parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a cleaning device is introduced into the sample cell to remove particulates, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The cleaning device combines multiple cleaning functions (wiping, brushing, and suction) into a single integrated apparatus that can be introduced into the sample cell. The wiper member, brush member, and suction tube are merged into one cleaning assembly that performs multiple cleaning actions simultaneously or sequentially, resolving the contradiction by achieving thorough cleaning without requiring multiple separate devices.
Solution Approach 2:
The cleaning device is designed with multi-functionality to address various cleaning needs within the sample cell. The wiper member cleans flat surfaces, the brush member reaches into corners and crevices, and the suction tube removes loose particulates. This universal cleaning approach ensures comprehensive cleaning effectiveness while using a single multi-functional device rather than multiple specialized tools.
2Productivity
If automated cleaning is implemented based on system-determined parameters, then productivity is improved, but device complexity increases
Solution Approach 1:
The system implements automated cleaning based on system-determined parameters, which suggests the use of feedback mechanisms to monitor sample cell conditions and trigger cleaning operations when necessary. The controller receives information about particulate accumulation or measurement quality and automatically initiates the cleaning sequence, improving productivity by eliminating manual intervention while using intelligent control rather than simple mechanical automation.
Solution Approach 2:
The cleaning device is designed to be self-contained with its own controller that manages the cleaning sequence autonomously. Once activated, the system determines when cleaning is needed and executes the cleaning cycle without requiring external operator input for each step. This self-service capability improves productivity by making the cleaning process independent and automatic.
