Filter Device with Conveying Means for Separating Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices used in processing machines clog quickly, leading to frequent replacements and increased costs, especially in one-way use filters.
Innovation Solution
Incorporation of conveying means with a conveying drive to move separated material away from the filter independently, preventing premature clogging by using blades and a scraper mechanism that can be controlled to remove material from the filter trough.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is advanced frequently to provide a fresh section for filtration, then the filtration capability is maintained, but the filter becomes clogged quickly and replacement costs increase
Solution Approach 1:
The filter belt is divided into multiple filter sections that can be independently advanced. The conveying means selectively advance individual filter sections that contain accumulated separated material, while leaving clean sections in place for continued filtration. This segmentation allows the filter system to maintain capability without frequent complete replacements.
Solution Approach 2:
Instead of discarding the entire filter belt when one section becomes clogged, the system recovers by selectively advancing only the affected filter sections to a discharge position where accumulated material is removed. The cleaned sections are then returned to the filtration path, extending the overall filter life and reducing replacement frequency.
2Productivity
If the filter belt is continuously advanced to prevent clogging, then material is removed from the filter, but the filter structure and drive mechanism become more complex
Solution Approach 1:
The conveying means are integrated with the existing filter belt structure, using the same support and drive mechanisms. The filter belt itself serves as the conveying medium, eliminating the need for separate conveying structures. This merging reduces overall system complexity while maintaining effective material removal capability.
Solution Approach 2:
The filter belt performs dual functions: filtration and self-conveying of separated material. The material accumulated on the filter belt is automatically transported along with the belt to the discharge position, eliminating the need for external conveying devices and simplifying the overall system architecture.
3Device complexity
If separated material is allowed to accumulate on the filter, then the filter structure remains simple, but the filter clogs quickly and requires frequent replacement
Solution Approach 1:
The filter system transitions from a static configuration to a dynamic one where filter sections can be selectively advanced independently. The conveying means enable the filter belt to dynamically reposition accumulated material, allowing the system to maintain simple structure while significantly extending operational duration through active material management.

AI summary
The apparatus has a tub (8) utilized for formation of a filter trough (8a) into which liquid material to be separated is introduced. A filter drive (15) is utilized for transporting a filter (10) by the filter trough. Conveyance units, drive gears (23) and a stripping device are utilized for conveying deposited material. Promotion drives (25, 35) are located relative to the filter to move the liquid material. The conveyance units are provided with circulating shovels (20a-20d) and movable scrapers (30). A rotary part (22) i.e. gear wheel, is arranged at the circulating shovels. An independent claim is also included for a method for separating material from a liquid.
