Multicage Ballast Water Filter Relocating Discharge to Lower Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-cage type ballast water filtering devices face challenges with spatial inefficiency due to elements being concentrated on the upper part, making maintenance difficult and increasing the risk of damage from collisions during backwashing, while also experiencing issues with back pressure and seal integrity.
Innovation Solution
The design relocates the discharge unit and backwash line to the lower part of the filtering device, with discharge pipes forming a single line, and incorporates double or triple structures to prevent collisions and enhance durability, along with pressure sensors and air injection systems to manage back pressure and ensure complete discharge and seal reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If discharge units and discharge pipes are installed on the upper part of the filtering device, then the structure is conventional and easy to implement, but the space required above the filtering device increases and maintenance becomes difficult
Solution Approach 1:
The patent inverts the conventional arrangement by relocating the discharge units and discharge pipes from the upper part to the lower part of the filtering device. This inversion resolves the spatial conflict by utilizing the lower space that was previously underutilized, thereby reducing the space requirement above the filtering device while maintaining ease of implementation through a straightforward repositioning of components.
Solution Approach 2:
The patent transitions from a two-dimensional arrangement (elements distributed on the upper surface) to a three-dimensional configuration by utilizing the vertical space below the filtering device. This dimensional change allows discharge units and pipes to be positioned in the lower region, effectively redistributing spatial requirements and reducing overhead space consumption.
2Length of stationary object
If multiple elements are concentrated on the upper part of the filtering device, then the structure is compact vertically, but maintenance and replacement work becomes difficult
Solution Approach 1:
The patent segments the discharge units from the main filtering body by positioning them separately at the lower part. This segmentation allows maintenance personnel to access and service the discharge units independently without needing to work in the constrained upper space, thereby improving ease of repair while maintaining overall vertical compactness of the system.
Solution Approach 2:
The patent introduces intermediate connection structures (such as flexible hoses or extendable pipes) that mediate between the upper filtering elements and the lower discharge units. This intermediary arrangement allows maintenance personnel to service upper elements without direct access to the upper space, as the intermediary components can be accessed or manipulated from the lower region.
3Adaptability or versatility
If discharge pipes are positioned separately for each filtering unit, then each unit can be independently controlled, but the structure becomes complex and space increases
Solution Approach 1:
The patent merges multiple separate discharge pipes into a single common discharge line that collects effluent from multiple filtering units. This merging approach maintains independent control capability through individual valves or control mechanisms at each filtering unit inlet, while the unified discharge structure reduces overall structural complexity and minimizes space requirements compared to having completely separate discharge pathways for each unit.

AI summary
The present invention relates to a device for filtering for treating ballast water by means of a filtering method, and more particularly, to a compact and operability-enhancing multicage-type device for filtering ballast water, which distributes to a lower portion of the device for filtering a discharge portion for discharging foreign substances after backwashing a filter and a backwash line, among features that are concentrated at an upper portion of the device for filtering, and communicates discharge tubes of each filtering unit in a single line, by considering the unique installation environment of the device for filtering that is coupled to a ship, thereby simplifying structure, reducing space required for installing the device for filtering in the upper portion of the device for filtering, allowing efficient maintenance by integrating foreign substance discharge and back pressure maintenance of each of the filtering units, and comprising double or triple components for preventing damage by collision of components in an automatic cleaning portion that move vertically to backwash the filter inside each of the filtering units, thereby preventing damage to the device and securing durability.
