Solution Overview
Problem
There is a lack of a simple apparatus configuration capable of supplying microbubbles to a slurry containing a metal or a metal compound during the manufacture of nonferrous metals or inorganic chemical products, and existing systems face challenges in performing solid-liquid separation or promoting solid-liquid and gas-liquid reactions effectively.
Innovation Solution
A slurry treatment apparatus comprising a treatment tank, pipes, a pump, and a microbubble generator with a throttle and gas supply tube, along with optional slurry separators like an intermediate chamber or cyclone, to facilitate microbubble generation and separation, enabling solid-liquid reactions and separations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple apparatus configuration is used for slurry treatment, then the device complexity is reduced, but the capability to supply microbubbles and perform solid-liquid separation is insufficient
Solution Approach 1:
The patent combines multiple functions (microbubble generation, slurry circulation, and solid-liquid separation) into a single integrated apparatus. The microbubble generator is directly connected to the slurry circulation system through pipes, and the separation function is incorporated into the same system, allowing one apparatus to perform multiple operations that would traditionally require separate equipment
Solution Approach 2:
The slurry treatment apparatus is designed as a multi-functional system that can simultaneously or sequentially perform microbubble supply, solid-liquid separation, and slurry circulation. This universal design allows a single apparatus to replace multiple specialized devices, reducing overall system complexity while maintaining comprehensive treatment capability
2Reliability
If a throttle is added to generate microbubbles, then the microbubble generation capability is improved, but the risk of clogging increases
Solution Approach 1:
The patent implements solid-liquid separation before the slurry reaches the throttle portion of the microbubble generator. By removing solid particles in advance through the separation unit, the slurry entering the throttle is pre-conditioned to prevent clogging, allowing the throttle to maintain its microbubble generation function without blockage
Solution Approach 2:
The separation unit acts as an intermediary between the slurry source and the microbubble generator throttle. It filters and conditions the slurry by removing solid particles that would cause clogging, while allowing the liquid phase to pass through to the throttle for microbubble generation, thus protecting the throttle from harmful solid particles
3Object-affected harmful factors
If solid-liquid separation is performed before microbubble generation, then the clogging risk is reduced, but the apparatus complexity increases
Solution Approach 1:
The separation unit and microbubble generator are integrated into a single connected system with pipes linking them directly. The slurry flows continuously from the separation unit through the throttle of the microbubble generator without requiring intermediate storage or handling equipment, merging multiple functions into one streamlined apparatus

Function Achieved in This Case
The apparatus effectively supplies microbubbles to the slurry, promoting reactions and separations with reduced clogging and complex apparatus configurations, ensuring long-term operation and efficient treatment.
Implementation Method 1
a pump, in which one end of the first pipe has a suction opening for sucking the slurry from the treatment tank, the other end of the first pipe is connected to a suction port of the pump
Implementation Method 2

Implementation Method 4
the slurry separator is a cyclone that separates the slurry fed from the pump into a pretreatment slurry containing, as a solid content, only particles smaller than the size of a throttle
