Reinforced Filter Plate Subframe for Easier Wear-Part Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical filter presses have heavy and bulky filter plate frames that hinder the replacement of wearing parts like seals and diaphragms, requiring the entire frame to be removed for maintenance.
Innovation Solution
A filter plate subframe with reinforced end sides and lighter flank sides, allowing it to be slidably received within a filter plate frame, facilitating easier manipulation and replacement of wearable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the filter plate frame is made sufficiently rigid to support the filter plate and withstand pressure differential, then the structural strength is improved, but the weight and bulkiness increase, making replacement of wearing parts difficult
Solution Approach 1:
The filter plate frame is divided into two functional parts: a rigid outer frame structure that provides structural support and pressure resistance, and a separate removable subframe that contains the wearing parts. This segmentation allows the heavy rigid structure to remain fixed while only the lighter subframe needs to be removed for maintenance.
Solution Approach 2:
The subframe containing the wearing parts (seals, diaphragms, gaskets) is extracted as a separate removable component from the main filter plate frame. This extraction allows the wearing parts to be replaced without removing the entire heavy frame structure.
2Strength
If the filter plate frame is made sufficiently rigid to support the filter plate and withstand pressure differential, then the structural strength is improved, but the device complexity increases, requiring the entire frame to be removed for maintenance
Solution Approach 1:
The filter plate frame is divided into two functional parts: a rigid outer frame structure that provides structural support and pressure resistance, and a separate removable subframe that contains the wearing parts. This segmentation allows the heavy rigid structure to remain fixed while only the lighter subframe needs to be removed for maintenance.
Solution Approach 2:
The subframe containing the wearing parts (seals, diaphragms, gaskets) is extracted as a separate removable component from the main filter plate frame. This extraction allows the wearing parts to be replaced without removing the entire heavy frame structure.
3Ease of operation
If the subframe is made lighter to facilitate removal, then the ease of operation is improved, but the rigidity decreases, causing excessive deformation under pressure differential
Solution Approach 1:
The filter plate frame is divided into two functional parts: a rigid outer frame structure that provides structural support and pressure resistance, and a separate removable subframe that contains the wearing parts. This segmentation allows the heavy rigid structure to remain fixed while only the lighter subframe needs to be removed for maintenance.
Solution Approach 2:
Different parts of the frame structure have different mechanical properties optimized for their specific functions. The outer frame is designed with high rigidity and strength to withstand pressure, while the subframe is designed with lower weight for easy removal, yet sufficient local rigidity to maintain its shape during operation.
4Stability of the object's composition
If the end sides are reinforced with reinforcement bars to increase bending stiffness, then the rigidity is improved, but the weight increases
Solution Approach 1:
Reinforcement bars are added only at the end sides of the subframe where bending stiffness is most needed to prevent deformation under pressure differential. The flank sides maintain a lighter construction, optimizing the weight-rigidity balance by applying reinforcement only where structurally necessary.

AI summary
A filter plate subframe for a filter plate frame assembly having a filter plate frame and a filter plate subframe slidably receivable therein. The subframe comprises separate periphery segments attached to each other so as to form a continuous, generally rectangular periphery region with flank sides and end sides. The flank sides have a linear density lower than that of the end sides, and the end sides have a bending stiffness higher than that of the end flank, while either or both of the first end side and the second end side are provided with a reinforcement bar for increasing the bending stiffness said end sides. A supporting surface is provided on a first planar side of periphery segments forming the flank sides the supporting surface.
