Filter Plate Insert With Elastic Seal For High Temperature Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter press systems experience breakage in the groove opening, especially at higher temperatures, due to the formation of a fragile lead between the groove and the channel opening, which can lead to costly repairs and operational disruptions.
Innovation Solution
The arrangement features a ring-shaped second recess with an elastic ring seal that protrudes beyond the investment surface, and a holding mechanism that secures the seal in the first recess, preventing solids from penetrating and eliminating the risk of breakage at high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If filter plates are used in high-temperature applications, then thermal stress resistance is improved, but the material becomes more brittle and prone to cracking
Solution Approach 1:
The filter plate structure is segmented into a main filter plate body and a separate annular insert that fits into a recess in the filter plate. This segmentation allows the insert to be made of a material better suited for withstanding thermal stresses without compromising the overall structural integrity of the filter plate, thereby resolving the contradiction between high-temperature operation and material brittleness.
Solution Approach 2:
The invention uses composite construction by combining the filter plate body with an annular insert made of different material properties. The insert can be made from materials with better thermal shock resistance and ductility, creating a composite structure that maintains strength while withstanding high-temperature operations without brittle failure.
2Reliability
If an annular projection is formed between the groove and channel opening, then sealing is improved, but the projection breaks off under thermal stress
Solution Approach 1:
The vulnerable annular projection that is prone to breaking off under thermal stress is extracted and replaced by an elastic ring seal that sits in a groove within the annular insert. This eliminates the brittle projection while maintaining the sealing function, as the elastic seal can deform and recover without breaking under thermal stress.
Solution Approach 2:
The invention replaces the rigid annular projection with an elastic ring seal, which is a flexible element. This elastic seal can accommodate thermal expansion and contraction without breaking, maintaining sealing reliability under high-temperature conditions where rigid projections would fail.
3Reliability
If a clamping ring with elastic ring seal is used, then sealing is improved, but manufacturing costs increase
Solution Approach 1:
The invention merges the seal retention function directly into the annular insert structure by providing a groove within the insert itself to hold the elastic ring seal. This eliminates the need for a separate clamping ring component, reducing the number of parts and assembly steps while maintaining reliable sealing, thereby lowering manufacturing costs.
Solution Approach 2:
The annular insert serves multiple functions: it provides structural reinforcement in the channel region, maintains spacing between filter plates, and incorporates the elastic ring seal for sealing. This multi-functionality consolidates what would otherwise require multiple separate components, simplifying manufacturing and reducing costs while maintaining sealing reliability.
4Strength
If the groove and seal area are made more robust, then breakage resistance is improved, but solids can still penetrate between the groove and seal
Solution Approach 1:
The elastic ring seal, being a flexible element, can deform to maintain contact with the groove surfaces even under varying operating conditions. This flexibility ensures that solids are effectively blocked while the seal accommodates thermal and mechanical stresses, preventing both breakage and solids penetration simultaneously.
Solution Approach 2:
The combination of the robust annular insert structure with the elastic seal creates a composite sealing system. The insert provides structural strength and positioning, while the elastic seal provides the actual sealing barrier that prevents solids penetration, with both components working together to resist breakage and contamination.

AI summary
The invention relates to an assembly consisting of a filter plate (1) for a filter press and an insert (6), wherein the filter plate (1) has a contact surface (5) for contacting another filter plate, which extends parallel to a plane (x, y) formed by the filter plate (1), and at least one channel opening (3) for forming a channel. The channel opening (3) passes through the filter plate (1) perpendicularly to the plane (x, y) formed by the filter plate (1) and is delimited by a channel surface (4) of the filter plate (1). The filter plate (1) has an annular first recess (8) in the transition between the channel surface (4) and the contact surface (5), said recess having a first annular delimiting surface (9) in which a holding groove (12) is formed. The assembly additionally has an insert (6) which corresponds to the annular first recess (8) and which comprises a second annular delimiting surface (13). In the assembly according to the invention, the insert (6) has an annular second recess (16) in which an elastic ring seal (7) is arranged that protrudes beyond the plane formed by the contact surface (5). The insert (6) has a receiving groove (17) in the region of the holding groove (12), said receiving groove being equipped with a holding ring (18) which engages into the holding groove (12) such that the insert (6) is held in the first recess (8) in the axial direction of the channel opening (3).
