Drum Filter Sludge Removal via Cantilever Support and Jetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtering devices for machine tool coolants suffer from clogging due to sludge accumulation between adjacent drum filters, which reduces their filtering capability and leads to maintenance issues.
Innovation Solution
A filtering device design featuring a plurality of drum filters, where one is cantilever-supported and the other is both-end supported, with jetting sections that clean the outer surfaces of the filters and a communicating part between the cantilever drum and the sidewall to prevent sludge accumulation, combined with a conveyor system to efficiently discharge sludge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple drum filters are arranged in parallel to enhance filtering capability, then filtering capability is improved, but sludge accumulates between adjacent drums causing clogging
Solution Approach 1:
The invention extracts the harmful stagnant space between adjacent drum filters by introducing a communicating part that connects the space between drums to the fluid discharge path. This allows sludge to be actively removed from the previously trapped inflow parts, preventing accumulation while maintaining the multi-drum filtering configuration.
Solution Approach 2:
The jetting means performs preliminary cleaning action by jetting fluid against the drum filters to remove sludge before it can accumulate in the inflow parts between drums. This preventive measure ensures that the communicating parts remain clear and functional, maintaining filtering capability without clogging.
2Ease of manufacture
If jetting means is positioned outside the drum filter to clean the surface, then cleaning effectiveness is improved, but sludge remains trapped in inflow parts between drums
Solution Approach 1:
The communicating part acts as an intermediary channel that connects the external jetting cleaning action to the internal inflow parts between drums. It allows the cleaning effect to extend into previously inaccessible areas, enabling sludge removal from between the drums without requiring direct access to those spaces.
Solution Approach 2:
The invention addresses the trapped sludge problem by opening a new dimensional pathway through the communicating part that extends from the external jetting zone into the internal inflow parts. This creates a three-dimensional flow path that allows fluid and sludge to move between the drum gaps and the discharge system.
3Stability of the object's composition
If both-end supported drum filter is used for stable support, then structural stability is improved, but sludge can still accumulate in inflow parts
Solution Approach 1:
The invention maintains the structurally stable both-end supported drum configuration while extracting the harmful stagnant inflow parts through the communicating part. This allows the drum to remain stable for support while the communicating part actively removes sludge from the spaces between drums, eliminating the accumulation problem without compromising structural integrity.

AI summary
A filtering device includes a filter tank, a first drum filter both ends of which are supported, and a cantilever second drum filter. A first end portion of the first drum filter is supported on a first sidewall of the filter tank. A second end portion of the first drum filter is supported on a second sidewall. An end portion of the second drum filter on the supported side is supported on the first sidewall. Between an end portion of the second drum filter on the non-supported side and the second sidewall, a communicating part is formed. A first jetting section jets a fluid against an outer circumferential surface of the first drum filter. A second jetting section is arranged in the vicinity of the second drum filter and jets the fluid against the second drum filter.
