Oscillating Filter Discs Prevent Clogging in Liquid Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid filtration devices face issues with clogging of filter pores due to substances in the liquid, leading to reduced filtration performance, and the movement of filter discs is limited as they can slip, compromising the filtration process.
Innovation Solution
The device employs a movement mechanism with oscillating drives to constantly move filter discs, ensuring no substances settle on the pores, and uses form-fitting connections and a central mandrel to prevent slipping, along with insert filter elements and a drainage system for efficient liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter discs are moved to prevent clogging, then filtration performance is improved, but filter discs may slip and lose position
Solution Approach 1:
The filter discs are designed to be movable rather than fixed, allowing them to oscillate and constantly change position. This dynamic configuration prevents substances from settling and clogging the filter pores, thereby maintaining high filtration performance throughout operation.
Solution Approach 2:
The harmful effect of clogging is eliminated by extracting the filter discs from a static state and placing them in a continuously moving state. The movement prevents substances from accumulating on the filter surface, effectively removing the clogging problem.
2Object-affected harmful factors
If filter discs are made movable to prevent settling, then clogging is reduced, but filtration reliability decreases due to slipping
Solution Approach 1:
The filter discs are designed to be movable rather than fixed, allowing them to oscillate and constantly change position. This dynamic configuration prevents substances from settling and clogging the filter pores, thereby maintaining high filtration performance throughout operation.
3Stability of the object's composition
If form-fitting connections are used to prevent slipping, then position stability is improved, but device complexity increases
Solution Approach 1:
The filter discs are designed to be movable rather than fixed, allowing them to oscillate and constantly change position. This dynamic configuration prevents substances from settling and clogging the filter pores, thereby maintaining high filtration performance throughout operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This setup maintains high filtration performance by preventing clogging and ensuring reliable movement of filter discs, allowing for high throughput and secure positioning, thus avoiding the risk of slipping and maintaining effective filtration.
Implementation Method 1
The filter discs experience a movement which they constantly pull away from under the liquid loaded with foreign substances
Implementation Method 2
The filter discs are preferably set in resonance vibration, so that only a small amount of energy is to be introduced by the oscillation drive to maintain this vibration
Implementation Method 3
The means for positively connecting the adjacent filter discs are designed in such a way that they can transmit forces
Implementation Method 4
The liquid is guided past filter pores. Some of the liquid makes its way through the filter pores

AI summary
In an appliance for filtering liquids, in particular waste water, with filter discs lying on top of one another and forming a flow path for a liquid to be filtered, wherein said appliance has at least one device for generating a movement of the filter discs, provision is made that the filter discs have means by which mutually adjacent filter discs are connected to one another with a form fit, these means being assigned to at least one circumferential portion of the filter disc. In particular, the means for form-fit connection are assigned to two mutually opposite circumferential portions of the filter disc.
