Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic filtration apparatuses are difficult to service due to the need to remove the entire core assembly for maintenance, making it inconvenient and expensive to replace individual magnet bars or insulation tubes, and the number of insulating tubes is fixed and cannot be adjusted.
Innovation Solution
A magnetic filter with a detachable magnetic core assembly featuring exchangeable elongated holder sleeves and a plate support assembly that allows for manual removal and replacement of magnet bars and sleeves without mechanical fixation, and a flexible number of sleeves to accommodate varying applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire core assembly is removed for maintenance, then all magnet bars and insulation tubes can be accessed, but the maintenance process becomes time-consuming and expensive
Solution Approach 1:
The magnetic core assembly is segmented into individual magnet bars, each housed in its own insulation tube. These tubes are arranged in a modular configuration within the filter housing, allowing individual tubes to be removed and serviced without requiring removal of the entire core assembly. This segmentation enables targeted maintenance of only the specific components that require attention.
Solution Approach 2:
The insulation tubes containing magnet bars are designed to be individually extractable from the filter housing. Each tube can be removed separately through the housing opening, allowing maintenance personnel to access and service specific magnet bars without disturbing other components. This extraction capability significantly reduces maintenance time and complexity.
2Ease of repair
If the entire core assembly is replaced, then serviceability is improved, but the cost and complexity of maintenance increases
Solution Approach 1:
The core assembly is divided into independent, modular units (insulation tubes with magnet bars) that can be serviced individually. This segmentation transforms a complex whole-system replacement task into simple individual component replacements, reducing both the complexity and cost of maintenance operations.
Solution Approach 2:
The design allows for economical replacement of individual insulation tubes containing magnet bars rather than requiring replacement of expensive entire core assemblies. This approach treats individual components as replaceable units, reducing maintenance costs and simplifying the replacement process.
3Adaptability or versatility
If the number of insulation tubes is fixed, then the structure is simple, but the filter cannot be adapted to different applications
Solution Approach 1:
The filter housing is designed with a dynamic, flexible configuration system that allows the number and arrangement of insulation tubes to be adjusted according to specific application requirements. This dynamic design enables the filter to adapt to different flow rates, contaminant loads, and application scenarios while maintaining a relatively simple overall structure.
Solution Approach 2:
The modular insulation tube design provides universal applicability across different filtration scenarios. The same basic tube-and-magnet-bar configuration can be replicated in different numbers and arrangements to suit various applications, from small-scale to large-scale filtration needs, without requiring fundamentally different design approaches.

Implementation Method 1
a magnetic core assembly which is detachably positioned in the interior and that includes: a magnet support assembly having at least one support plate; and a plurality of elongated non-magnetic sleeves that are removably disposed in the magnet support assembly with each elongated sleeve being vertically orientated and spaced apart from one another and each elongated sleeve configured to accommodate one or more magnets that are disposed therein

AI summary
A magnetic filter employs a magnetic core assembly that incorporates a plurality of exchangeable holder sleeves, each enclosing permanent magnets. Neither the sleeves nor magnetic bars are mechanically fixed to the filter housing. The magnet bars and holder sleeves are individually accessible. The number of holder sleeves in the magnetic core assembly is flexible. The magnetic filter in equipped with a screen that partially encloses the elongated holder sleeves to treat streams that contain degradation sludge, iron containing particles or flakes, and non-magnetic polymeric materials. In operation, a feed stream initially contacts the magnetic core assembly where paramagnetic contaminants become deposited onto the exterior surface of the holder sleeves under direct influence of strong magnetic field generated by the magnet bars. The mesh screen cylinder subsequently captures non-magnetic and weakly magnetic contaminants of a certain size before the cleaned stream exits the magnetic filter.
