Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filterpresses with large filtering plates are not adapted to compress sludge homogeneously and efficiently, limiting their capacity and suitability for high flow rates and certain types of sludge.
Innovation Solution
A filterpress structure with a unique arrangement of three overlapping couples of pneumatic cylinders and support beams, allowing for a uniform distribution of load on large filtering plates, capable of withstanding pressures up to 20 Bar, and an opening system with actuation sliders and grippers for efficient plate movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional filterpress structures with large filtering plates are used, then the filtering surface area is increased, but the compression homogeneity and effectiveness deteriorates
Solution Approach 1:
The patent divides the compression system into multiple independent pneumatic cylinders arranged in overlapping couples. Each cylinder independently compresses a specific section of the filtering plates, ensuring uniform pressure distribution across the entire large filtering surface. This segmentation allows each cylinder to maintain effective compression control while collectively covering the full area.
Solution Approach 2:
The patent implements local quality by positioning pneumatic cylinders at specific locations corresponding to different sections of the filtering plates. Each cylinder applies compression force locally to its designated area, ensuring that every region of the large filtering surface receives appropriate and homogeneous compression pressure.
2Productivity
If conventional filterpress structures are used, then the structural simplicity is maintained, but the treatment capacity and performance deteriorates
Solution Approach 1:
The patent merges multiple pneumatic cylinders into overlapping couples arranged in a coordinated manner. This merging allows the system to achieve double the performance of conventional filterpresses while maintaining a structural conformation that is substantially equal to and comparable with existing structures. The overlapping arrangement of cylinder couples enables efficient space utilization and coordinated compression action.
3Adaptability or versatility
If conventional filterpress structures are used, then the ease of manufacture is preserved, but the adaptability to different sludge types and high flow rates deteriorates
Solution Approach 1:
The patent designs the filterpress structure with universal applicability by using multiple overlapping couples of pneumatic cylinders that can effectively handle different types of sludge including difficult-to-treat inert and clay materials. The standardized coupling arrangement and support frame design maintain ease of manufacture while providing the versatility needed for high flow rates and various sludge characteristics.

AI summary
It is described a filterpress structure (100) comprising a support frame (10) having a first fixed shoulder (1) and a second fixed shoulder (2) opposite to each other; a movable shoulder (3) arranged between said first fixed shoulder (1) and said second fixed shoulder (2). A plurality of filtering plates (20) are functionally arranged between the movable shoulder (3) and the second fixed shoulder (2) that extend along a longitudinal axis (X). Actuating means (40) are adapted to move selectively the movable shoulder (3) between a closed configuration and an open configuration of the filtering plates (20). The actuating means (40) comprise at least one first couple of pneumatic actuating cylinders (41) parallel to each other arranged on a first reference plane (P1) and a second couple of pneumatic actuating cylinders (42) parallel to each other arranged on a second reference plane (P2) overlapped to said first reference plane (P1).
