Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing primary dewatering and densifying methods for flocculated slurry, such as those used in the Oil Sands Industry, are unable to produce high-density products efficiently, while secondary methods are costly and have low throughput.
Innovation Solution
An apparatus and method that utilizes a treatment surface to interact with the slurry through displacement and motion, causing mechanical kneading or massaging actions to separate liquid, with a porous or foraminous surface and displacement mechanism to facilitate gentle squeezing and compaction, allowing for high-throughput and low-cost dewatering and densification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gravity assisted consolidation processes are used for primary dewatering, then throughput is high and cost is low, but density of the product is not high
Solution Approach 1:
The treatment surface is configured to be movable relative to the slurry, enabling dynamic mechanical interaction (kneading/massaging action) that enhances dewatering effectiveness without sacrificing throughput. This dynamic motion allows the system to achieve high-density product while maintaining high throughput capacity.
Solution Approach 2:
A treatment surface acts as an intermediary between the slurry and the dewatering process. This intermediate element facilitates liquid separation through its specific configuration and motion, enabling effective dewatering while maintaining system throughput and reducing direct mechanical stress on the slurry.
2Manufacturing precision
If mechanical compaction processes are used for dewatering, then density of the product is high, but power consumption is high and throughput is low
Solution Approach 1:
The system employs dynamic motion of the treatment surface (kneading/massaging action) rather than static high-pressure compression. This dynamic approach achieves effective dewatering and high product density with significantly lower power consumption compared to traditional mechanical compaction methods.
Solution Approach 2:
The invention replaces aggressive mechanical compaction with a gentler mechanical interaction system. The treatment surface motion creates a kneading effect that separates liquid through controlled mechanical action rather than high-pressure compression, reducing power requirements while maintaining dewatering effectiveness.
3Manufacturing precision
If mechanical compaction processes are used for dewatering, then density of the product is high, but throughput is low
Solution Approach 1:
The movable treatment surface creates continuous motion that processes slurry efficiently without creating bottlenecks. This dynamic approach maintains high throughput while achieving high product density, unlike static mechanical compaction systems that require slow processing times.
Solution Approach 2:
The treatment surface serves as an intermediary that facilitates efficient liquid separation through its motion. This intermediate mechanism enables high throughput processing while achieving high-density product, bridging the gap between throughput and density that exists in traditional systems.
