Strainer Bar Connection Using Filler Pockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strainer apparatuses with bar screening construction face challenges in achieving a reliable and stable connection between strainer bars and support elements due to inaccuracies in attachment caused by high temperatures and thermal expansion, requiring precise matching of contact surfaces and geometry, which complicates the manufacturing process and can lead to inconsistent straining slot geometry.
Innovation Solution
The introduction of pockets between the strainer bars and support elements, which are filled with a filler material to create a permanent and stable connection, allowing for precise orientation and uniform production of straining slots with enhanced manufacturing flexibility, where the pockets can be formed by shaping the strainer bars and support elements without additional machining, and filled with adhesives or clip-shaped elements for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding or brazing is used to permanently connect strainer bars to support elements, then a permanent connection is achieved, but thermal expansion and high temperatures cause inaccuracies in attachment and inconsistent straining slot geometry
Solution Approach 1:
A pocket is introduced as an intermediary space between the strainer bar and support element, filled with filler material that acts as a mediator to transmit forces while accommodating dimensional variations, thereby preventing thermal expansion from causing attachment inaccuracies
Solution Approach 2:
The design allows for dimensional variations and tolerances in the pocket dimensions, changing the geometric parameters to accommodate thermal expansion and manufacturing variations without compromising connection strength or attachment precision
2Manufacturing precision
If precise matching of contact surfaces and geometry is required to avoid thermal expansion inaccuracies, then attachment precision is improved, but manufacturing process complexity increases
Solution Approach 1:
The connection interface is segmented into distinct components: the strainer bar, the pocket space, and the support element, allowing each to be manufactured independently with standard tolerances rather than requiring precise matching of entire contact surfaces
Solution Approach 2:
Instead of requiring precise matching across entire contact surfaces, only specific local areas (the pocket region) require controlled dimensions, while other areas can have greater tolerances, simplifying the overall manufacturing process
3Ease of manufacture
If conventional attachment methods are used without pockets, then manufacturing process is simpler, but connection reliability and straining slot uniformity deteriorate
Solution Approach 1:
The filler material in the pocket serves as a mediator that provides reliable force transmission between strainer bars and support elements while accommodating manufacturing variations, achieving connection reliability without requiring complex precision manufacturing processes

AI summary
The invention relates to a strainer apparatus, such as a strainer basket, a strainer cylinder and the like, wherein slits or gaps are formed between strainer bars (6). The base of the strainer bars is received in receiving recesses (8) adapted to the dimensions of the base of the bars, in a support element (3). The support element can also be a reinforcing or strengthening element, and the strainer bars (6) are permanently fixed to the respective support element (3). At least one pocket (10, 11) that can be filled with a filler material is provided between each support element (3) and each associated strainer bar (6), at least on the edge region (7) of the respective receiving recess (8). In the strainer apparatus according to the invention, the pocket interrupts the contact surface between the outer contour of the strainer bar (6) and the inner contour of the associated receiving recess in the support element (3), such that a pre-determined intermediate space is intentionally formed in the form of a pocket (10; 11), at least on the edge region (7). The pocket is then filled with a homogeneous or composite filler material used as a fixing means, wherein the filler material may be composed of, for example, an adhesive. In this way, a permanent solid connection can be produced between strainer bar (6) and support element (3).
