Solution Overview

Problem

Conventional water straining equipment in industrial applications lacks sufficient capacity to handle flows exceeding 4000 gallons per minute, leading to leakage and inadequate filtration, which can damage downstream equipment and affect product quality.

Innovation Solution

A fluid strainer design featuring a body, lid, and a tube sheet with filter openings, concentric seals, and filter retainers, capable of handling high flow rates with reduced leakage and pressure drop, incorporating redundant seals and a robust filter media configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional water straining equipment is used, then the equipment structure is simple, but the filtration capacity is insufficient for flows exceeding 4000 gallons per minute

Engineering Contradiction:
Improvefiltration capacityVSAvoidequipment structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The strainer is divided into multiple functional components: a body, a tube sheet with multiple filter openings, multiple filter retaining baskets, and a lid. This segmentation allows the filtration capacity to be increased by adding more filter openings and baskets while maintaining a manageable structure for each component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-chamber conventional strainer to a multi-chamber design with the tube sheet creating first and second chambers. This dimensional change allows fluid to flow through multiple filtration stages simultaneously, dramatically increasing filtration capacity while organizing complexity into distinct spatial zones.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If filtration equipment is used above its rated capacity, then the productivity increases, but leakage and inadequate filtering occur

Engineering Contradiction:
Improveflow rateVSAvoidfiltration effectiveness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Multiple filter openings and corresponding filter retaining baskets distribute the high flow rate across numerous parallel filtration paths. This segmentation prevents any single filter element from being overloaded, maintaining filtration effectiveness even at flow rates exceeding 4000 gallons per minute.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter retainers are pre-configured with spring elements that automatically engage with the tube sheet when the lid is closed. This preliminary action ensures proper sealing and positioning of all filter baskets before high-flow operation begins, preventing leakage and ensuring reliable filtration from the start of operation.

Inventive Principle:
Principle #10Preliminary action

3Loss of energy

If conventional strainer design is used, then the device complexity is low, but pressure drop across the strainer is high

Engineering Contradiction:
Improvepressure dropVSAvoidstrainer design
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The multi-chamber design with the tube sheet creates multiple parallel flow paths through the first and second chambers. This dimensional reorganization allows fluid to be distributed across numerous filter openings simultaneously, reducing the velocity and pressure drop across each individual filter element while maintaining high overall filtration capacity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

AI summary

Embodiments herein describe a fluid strainer that includes a body and a lid. The inner surfaces of walls of the body and lid define a cavity therein. The body wall has a fluid inlet opening and a fluid outlet opening. A tube sheet disposed within the cavity divides the cavity into first and second chambers. The tube sheet has a plurality of filter openings and a fluid inlet. The fluid inlet is open to the first chamber. A plurality of filter retaining baskets are disposed in respective ones of the filter openings. A plurality of filter retainers are provided, each of which is configured to removably attach to the tube sheet and extend into a respective one of the filter retaining baskets. An internal fluid inlet pipe is disposed within the second chamber and couples the fluid inlet opening to the fluid inlet opening of the tube sheet.
