Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing separator devices for hydronic heating systems are limited in effectiveness due to their small size, which restricts particle separation efficiency and requires significant vertical space for installation, and often risk damage during installation due to improper handling of right-angle connectors.
Innovation Solution
A separator device with a three-chamber design featuring counter-rotating flows and a removable release tool, allowing for flexible installation and minimizing pressure drop, with integral flow guides and deflectors to enhance separation efficiency and simplify installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the separator chamber is made small to reduce device size, then the device can be fitted in small spaces, but the obstruction means have limited ability to slow the flow rate and separation effectiveness is reduced
Solution Approach 1:
The separator device is divided into multiple chambers (first chamber with swirl flow, second chamber with opposite direction flow, and separation chamber with obstruction means). This segmentation allows each chamber to perform a specific function, enabling the device to maintain compact size while achieving effective particle separation through the cumulative effect of multiple separation stages.
Solution Approach 2:
The patent introduces a third dimension by adding the swirl flow component in the first chamber and the counter-flow in the second chamber. Instead of relying solely on linear flow reduction, the device uses rotational and counter-directional flow patterns to enhance particle separation efficiency within a compact volume, effectively utilizing multi-dimensional flow dynamics.
2Ease of repair
If a removable insert of similar longitudinal extent to the cylindrical housing is provided, then particles can be removed during service, but the device requires vertical space between horizontal surfaces of at least twice the height of the housing for installation
Solution Approach 1:
The removable insert is designed with a length substantially less than the cylindrical housing, allowing it to be easily inserted and removed through the top opening. The dynamic design enables the insert to be accessed and cleaned without requiring the device to be installed in locations with large vertical clearance, as the shorter insert can be manipulated through the existing top opening of the housing.
3Ease of manufacture
If right-angle connectors are attached to the separator device and then screwed onto pipework, then installation is simplified, but the torque of the spanner may be sufficient to break an inlet or outlet port from the separator
Solution Approach 1:
The patent introduces a fitting as an intermediary component between the separator device and the pipework. This fitting includes connectors that attach to the inlet and outlet ports of the separator device and then connect to the pipework. The intermediary fitting distributes and absorbs the mechanical stress and torque, preventing direct transmission of installation forces to the separator device ports and eliminating the risk of port breakage during installation.

AI summary
A separator device for removing particles from suspension in a liquid includes a housing having first and second chambers with apertures for ingress and egress of liquid into the first chamber. Means are provided for setting up a swirl of liquid within the first chamber. Apertures enable flow of liquid between the first chamber and the second chamber. Means are also provided for setting up a swirl of liquid within the second chamber. The swirl in the second chamber is in substantially the opposite direction to the swirl in the first chamber, and there is no substantial flow in the second chamber which is in the same direction as the swirl in the first chamber.
