Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filtration systems are inadequate for high-pressure cleaning applications with high concentrations of solids, fat, fibers, or abrasive substances, as they are inefficient, costly, and require frequent maintenance.
Innovation Solution
A high-pressure cleaning system incorporating filtration subsystems connected in series, including a pre-filter, vortex separation subsystem, filtration bag subsystem, and a settling structure, which reduces power requirements and eliminates rotary parts, allowing for self-cleaning and improved filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional rotary filtration system is used, then filtration efficiency is improved, but power consumption and device complexity increase
Solution Approach 1:
The patent replaces the rotary mechanical filtration system with a static filtration system that uses a filtration bag and vortex separation. The vortex separation uses fluid dynamics rather than mechanical rotation to separate solids from liquids, eliminating the need for motors and rotary parts while maintaining effective filtration.
Solution Approach 2:
The filtration system is designed to be self-cleaning through the vortex separation mechanism. The vortex flow automatically separates and removes solids from the filtration bag, eliminating the need for external cleaning mechanisms or manual intervention, thus reducing power consumption while maintaining filtration efficiency.
2Reliability
If a conventional rotary filtration system is used, then filtration efficiency is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent eliminates rotary parts, motors, and associated mechanical components by using a static filtration bag combined with vortex separation. This substitution dramatically simplifies the device structure while maintaining effective solid-liquid separation capability.
Solution Approach 2:
The patent extracts and removes the complex rotary filtration mechanism from the system, retaining only the essential filtration function through a simple bag filter. The vortex separation mechanism further simplifies the system by passively removing solids without requiring complex mechanical components.
3Quantity of substance
If conventional filtration is used for high solid content fluids, then filtration capacity is maintained, but filtration efficiency and durability decrease
Solution Approach 1:
The patent segments the filtration process into two distinct stages: primary filtration through the filtration bag that captures solids, and secondary separation through vortex separation that further clarifies the filtrate. This segmentation allows the system to handle high solid content fluids effectively while maintaining high filtration efficiency.
Solution Approach 2:
The vortex separation acts as an intermediary mechanism between the filtration bag and the final filtrate output. It provides an additional separation stage that enhances filtration efficiency by removing fine particles and solids that pass through the bag filter, thereby improving the quality of the final filtrate.
