Solution Overview
Problem
Existing devices for separating tramp metals from liquid raw materials expose magnets to the outside, allowing air-borne metals to be attracted into the system, and require manual removal of components for effective cleaning, leading to incomplete separation and operational inefficiencies.
Innovation Solution
A device comprising a tank, non-magnetic holders, a magnetic unit with telescopic enclosure, and a rinsing unit, along with a driving mechanism to move the magnetic unit between positions, allowing for continuous separation and cleaning of tramp metals, and a method involving sequential operation of magnetic attraction and rinsing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If magnets are exposed to the outside for separating tramp metals, then tramp metals in liquid raw materials can be attracted and removed, but air-borne metals will be attracted by the magnets and brought into the interior of the tubes
Solution Approach 1:
The patent extracts the magnets from direct exposure to the outside environment by placing them inside a housing structure. The housing has openings that allow liquid raw materials to pass through while preventing air-borne metals from reaching the magnets. This extraction of the harmful exposure path resolves the contradiction by maintaining separation efficiency while preventing contamination.
Solution Approach 2:
The housing structure acts as an intermediary between the magnets and the external environment. It provides a controlled interface where liquid raw materials can access the magnetic field through openings, while air-borne metals are blocked. This intermediary structure enables the magnets to perform their separation function without direct exposure to harmful airborne contaminants.
2Ease of operation
If manual removal of the shell for receiving magnets and tubes is performed to clean tramp metals, then the shell can be accessed for cleaning, but the liquid whose irons have not been removed will still flow through the pipeline
Solution Approach 1:
The patent introduces a movable magnetic unit that can be shifted between a working position (where magnets are exposed to attract tramp metals) and a cleaning position (where magnets are retracted into the housing). This dynamic positioning allows the system to alternate between separation and cleaning modes without manual disassembly, maintaining continuous operation and resolving the contradiction between cleaning accessibility and continuous separation.
Solution Approach 2:
The system implements periodic cycling between separation mode (magnetic unit in working position) and cleaning mode (magnetic unit in cleaning position). This periodic action allows automated cleaning to occur without stopping the overall process, as the magnetic unit can be retracted and cleaned while the system prepares for the next separation cycle, thus maintaining productivity while enabling easy cleaning.
3Object-affected harmful factors
If the magnetic unit is retracted into the housing for cleaning, then air-borne metals are prevented from being attracted, but the openings must be designed to allow both liquid flow and magnet retraction
Solution Approach 1:
The patent resolves the design challenge by using a telescopic or sliding mechanism that moves the magnetic unit along the longitudinal axis of the housing. This dimensional movement allows the magnets to be positioned either inside the housing (protected from airborne metals) or outside (exposed for separation). The openings in the housing are positioned to allow liquid flow when magnets are in the working position, while the retraction mechanism provides protection when magnets are retracted, thus resolving the contradiction through spatial dimensionality.
