Bubble Measurement Device Using Transparent Slope for Turbidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring bubble size and quantity in ore slurries face challenges due to high turbidity, which complicates image capture and accurate determination, especially when dealing with microscopic bubbles, as they adhere to measurement device surfaces and are difficult to distinguish from solid particles.
Innovation Solution
A bubble measurement device with a measurement chamber and image capturing system that introduces bubbles from below, using a transparent slope and adjustable bubble introduction valve to control the introduction time based on pipe shape, liquid properties, and air supply, allowing for clear image capture and differentiation between bubbles and solid materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bubbles are introduced into a measurement chamber with ore slurry using existing methods, then bubble size and quantity can be measured, but turbidity from solid particles flows into the device at the same time as bubbles, making image capture difficult and reducing measurement precision
Solution Approach 1:
The patent introduces bubbles into the measurement chamber before solid particles (ore slurry) are introduced. This preliminary action ensures that bubbles are already positioned and visible in the clear liquid before turbidity from solid particles enters the chamber, allowing for clear image capture and accurate measurement without the interference of mineral particles
Solution Approach 2:
The patent separates the introduction of bubbles from the introduction of ore slurry by using distinct introduction pipes and timing mechanisms. Bubbles are introduced through a dedicated bubble introduction pipe while ore slurry is introduced separately through a slurry introduction pipe, extracting the harmful turbidity effect from the bubble measurement process
2Productivity
If the air drive valve is opened for a predetermined period to collect bubbles, then bubbles can be captured for measurement, but turbidity flows into the device slightly later or at the same time, limiting the image-capturing period and reducing productivity
Solution Approach 1:
Bubbles are introduced into the measurement chamber in advance before the ore slurry is introduced. The bubble introduction valve is opened to allow bubbles to enter the clear liquid, and once sufficient bubbles are collected, the valve is closed before the slurry introduction begins, maximizing the image-capturing time window
Solution Approach 2:
The patent uses periodic opening and closing of the bubble introduction valve to control bubble flow into the measurement chamber. This periodic action allows for controlled bubble collection during specific time intervals, followed by closure to prevent turbidity entry, enabling repeated measurement cycles
3Reliability
If small bubbles (1-100 μm) are used to improve flotation yield, then bubble effectiveness increases, but small bubbles adhere to the inside of the measurement device, making accurate size and quantity determination difficult
Solution Approach 1:
The patent extracts small bubbles from the ore slurry environment by introducing them into a separate measurement chamber filled with clear liquid. This isolation prevents the bubbles from adhering to the external surfaces of the measurement device while allowing their size and quantity to be accurately determined through image capture in the turbidity-free environment
Solution Approach 2:
The clear liquid in the measurement chamber serves as an intermediary medium between the bubbles and the measurement device. This intermediary prevents direct contact between bubbles and device surfaces, eliminating adhesion issues while maintaining bubble integrity for accurate measurement
