Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter centrifuges face challenges in securely attaching filter cloths without tools, leading to potential wrinkles and increased production and storage costs due to the need for multiple types of cloths and clamping means, especially when handling various solid-liquid suspensions.
Innovation Solution
A filter centrifuge design featuring a filter drum with a circumferential groove and a clamping ring that is radially spring-elastically pliable, allowing the filter cloth to be securely held without tools, using a circumferential ribbon structure that can be easily deformed to fit into the groove and is adapted for multiple applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional clamping means are used to attach filter cloth, then the filter cloth can be secured in the filter drum, but the mounting process requires tools and multiple steps, increasing installation time and complexity
Solution Approach 1:
The patent replaces traditional mechanical clamping systems requiring tools with a spring-elastic clamping ring that uses elastic deformation for automatic clamping. The clamping ring utilizes its own elastic properties to deform and secure the filter cloth without external tools, transforming a tool-based mechanical system into a self-contained elastic system.
Solution Approach 2:
The patent employs parameter changes by utilizing the spring-elastic properties of the clamping ring. The ring's elastic modulus and deformation characteristics are designed to allow easy installation through controlled deformation while maintaining secure clamping force. The parameter of elastic pliability enables the ring to transition between installed and clamped states without tools.
2Productivity
If the filter drum rotates at high speed during centrifuging, then separation efficiency is improved, but the filter cloth may displace or wrinkle due to centrifugal forces
Solution Approach 1:
The patent applies the anti-weight principle by using the spring-elastic clamping ring to provide a counteracting force against the centrifugal forces generated during high-speed rotation. The elastic ring maintains constant radial pressure on the filter cloth, counterbalancing the outward centrifugal forces that would otherwise cause displacement or wrinkling of the filter cloth.
3Adaptability or versatility
If multiple types of filter cloths and clamping means are used for different applications, then versatility is improved, but production and storage costs increase
Solution Approach 1:
The patent implements universality through the spring-elastic clamping ring design that can accommodate different filter cloth types and sizes. The elastic properties and adjustable clamping force allow a single clamping ring design to serve multiple applications across different solid-liquid suspension processing needs, eliminating the requirement for multiple specialized clamping means.
4Reliability
If the filter cloth is firmly clamped to prevent displacement, then reliability is improved, but the mounting process becomes more complex requiring specialized clamping means
Solution Approach 1:
The patent merges the functions of multiple separate components (clamping mechanism, mounting system, and securing system) into a single integrated spring-elastic clamping ring. This unified structure combines the mounting and securing functions in one element, reducing device complexity while maintaining reliable filter cloth attachment through the ring's inherent elastic clamping action.
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 solution enables quick and cost-effective installation of the filter cloth, preventing displacement and reducing production and storage costs, while maintaining a secure attachment to prevent damage and contamination.
Implementation Method 1
a clamping ring which is formed separately therefrom, is formed closed and as one piece and is radially spring-elastically pliable
Implementation Method 2
Due to the rotation of the filter drum, the solid-liquid-suspension to be filtered is pushed radially outwards to the radially inner wall of the filter drum and therefore to the filter cloth
Implementation Method 3
The liquid of the suspension penetrates the filter cloth as well as the solid matter depositing on the filter cloth and is discharged or rather centrifuged from the filter drum

AI summary
A Filter centrifuge (1) for filtering solid from a solid-liquid-suspension may comprise: a filter drum (10) comprising a circumferential groove (19) which groove is formed in an inner surface (21) of the filter drum (10) and runs in circumferential direction of the filter drum (10); a filter cloth (30) which is insertable into the filter drum (10), forms, at least when inserted into the filter drum (10), a hollow cylindrical shape which shape defines an axial direction (X) and a radial direction (R) and which shape has circumferential edges at the axial ends (32) thereof, is configured to hold back the solid from the suspension to be filtered and to let the liquid of the suspension to be filtered pass therethrough, and comprises at at least one of the circumferential edges (32) a circumferential ribbon structure (34; 34'; 34"; 34'"; 34"") which is formed by at least two ribbon layers (36,38; 36',38';36",38"; 36"',38"',39; 36"") which at least substantially overlap each other in the radial direction and are attached to one another, wherein, with the filter cloth (30) inserted into the filter drum (10), the circumferential ribbon structure (34; 34'; 34"; 34'"; 34"") is received in the circumferential groove (19) of the filter drum (10); and a clamping ring (40) which is formed separately from the filter cloth (30), is formed closed and as one piece, is radially spring-elastically pliable, and is disposable inside of the filter drum (10) opposite to the circumferential groove (19) so as to press the circumferential ribbon structure (34; 34'; 34"; 34'"; 34""), received in the circumferential groove (1), radially outwardly against the filter drum (10) such that the filter cloth (30) thereby remains firmly held in the filter drum (10).
