Inline Strainer Drain-Line Coupling for Fast Screen Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inline-type strainers with drain lines and detachable screens face difficulties in disassembling and reconstructing the drain line within a narrow housing, making assembly and maintenance time-consuming and labor-intensive.
Innovation Solution
The inline-type strainer design includes a housing with an access hole, a detachable lid, and a screen support structure that allows the screen to be easily removed and reassembled, with a drain line mechanism that can be constructed and disassembled by attaching or detaching the lid, eliminating the need for internal disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drain line is provided inside the housing to discharge filtered residues, then the filter surface can be reproduced by cleaning in place, but the disassembly and reconstruction of the drain line becomes significantly difficult and time-consuming
Solution Approach 1:
The drain line is divided into two separate segments: an upper discharge flow path formed in the lid and a lower discharge flow path formed in the housing. These segments are connected through a coupling mechanism that allows easy attachment and detachment, eliminating the need for complex internal disassembly while maintaining the drain line's functionality for filter surface reproduction.
Solution Approach 2:
The coupling mechanism features a coupling hole in the lid and a coupling protrusion in the housing that fit together like nested components. The upper discharge flow path in the lid couples with the lower discharge flow path in the housing, creating a seamless drain line connection that is both reliable for filtering and easy to assemble/disassemble.
2Ease of repair
If the screen is made detachable from the housing for external cleaning, then cleaning with visual confirmation becomes possible, but the drain line must be disassembled and reconstructed which takes time and effort
Solution Approach 1:
The overall strainer structure is segmented into removable components: the lid (with screen and upper discharge flow path) can be detached from the housing (with lower discharge flow path). This allows the screen to be removed for external cleaning without requiring disassembly of the drain line's internal structure, significantly reducing maintenance time.
Solution Approach 2:
The coupling mechanism between lid and housing is designed to be dynamically adjustable, allowing easy attachment and detachment. This dynamic connection enables rapid screen removal and reassembly, transforming a previously time-consuming maintenance operation into a quick process while maintaining drain line integrity.

Function Achieved in This Case
This design simplifies the assembly and maintenance of the strainer by allowing quick construction and disassembly of the drain line, enabling efficient cleaning and replacement of the screen, thereby optimizing filter surface reproduction and reducing maintenance time.
Implementation Method 1
a screen 12 disposed in the filter chamber 8 and configured to filter a liquid flowing in through the inflow port 5
Implementation Method 2
foreign matters held on an inner surface of the screen can be discharged to the outside of the housing by a fluid pressure by opening the drain line

AI summary
An inline-type strainer including a drain line and a screen configured to be attachable to and detachable from a housing is provided. A screen is supported to be attachable to and detachable from a lid. A lid coupling mechanism that couples a housing and the lid when the lid is attached to the housing is provided between a bottom surface of the housing facing the filter chamber and a lower end of the lid. A lower discharge flow path is formed in a lower coupling element on a side close to the housing constituting the lid coupling mechanism, and an upper discharge flow path is formed in the upper coupling element on a side close to the lid constituting the lid coupling mechanism. When the lid is attached to the housing, a coupling state is established between the upper and lower coupling elements, and the upper and lower discharge flow paths communicate with each other, and thus a drain line is constructed.
