Filtration Filter Flow Inversion for Continuous Clogging Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Filtration apparatuses face frequent clogging due to suspended matter, requiring periodic backward cleaning or disassembly for maintenance, which disrupts continuous sample filtration, especially when dealing with high-suspended matter samples.
Innovation Solution
A filtration apparatus with a sample discharge port on the opposite side of the filtration chamber, equipped with an opening and closing mechanism that allows the sample to flow over the filtration filter to dislodge and discharge accumulated suspended matter, eliminating the need for backward cleaning and disassembly by automatically or manually controlling the flow based on pressure or time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backward cleaning is performed to remove suspended matter from the filter surface, then the filter can be cleaned, but sample filtration must be interrupted and cleaning solution or gas must be introduced
Solution Approach 1:
Instead of introducing cleaning solution from the filtrate side backward through the filter, the invention introduces sample from the sample introducing port forward through the filter. The sample flow direction is inverted relative to traditional backward cleaning, allowing suspended matter to be removed while maintaining continuous operation
Solution Approach 2:
The sample itself serves as the cleaning medium. The sample introduced from the sample introducing port automatically cleans the filter surface by flowing through the filter, eliminating the need for separate cleaning solution introduction and system disassembly
2Productivity
If the filtration filter is used to filter samples with large amounts of suspended matter, then filtration can be performed, but the filter clogs frequently requiring frequent cleaning
Solution Approach 1:
The system enables continuous filtration without interruption for cleaning. By introducing sample continuously from the sample introducing port and using this sample flow to prevent clogging, the filtration process maintains uninterrupted operation even with high suspended matter loads
Solution Approach 2:
The sample flow is used preliminarily to prevent suspended matter accumulation before clogging occurs. By continuously introducing sample that flows through the filter, the system preemptively removes suspended matter before it can accumulate to clogging levels
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
This solution prevents filter clogging by regularly removing surface-bound suspended matter without interrupting sample filtration, reducing maintenance needs and ensuring continuous operation of the filtration apparatus.
Implementation Method 1
the suspended matter stuck on an outer surface of the disc filter is unstuck by the sample flowing by the disc filter

AI summary
A filtration apparatus includes: a filtration chamber; a sample introducing port for introducing a sample into the filtration chamber; a sample discharge port disposed at a position on an opposite side of the filtration chamber from the sample introducing port; a filtration filter provided in the filtration chamber to filter the sample introduced from the sample introducing port; and a filtrate discharge port for discharging filtrate which has passed through the filtration filter. The filtration filter is disposed such that its filter face is parallel to a flowing direction of the sample introduced from the sample introducing port when the sample discharge port is open. An opening and closing mechanism for opening and closing the sample discharge port is disposed between the filtration chamber and the sample discharge port.
