Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for separating suspended matter from liquids, such as those used in dental laboratories or pottery workshops, face challenges in ease of assembly and maintaining a high separation efficiency, particularly when dealing with sudden influxes of contaminated water.
Innovation Solution
The device features a container divided into chambers with narrow openings between them, arranged in a star shape, which slows down the liquid flow rate and prevents re-suspension of settled matter, allowing for easier assembly and improved separation efficiency by using partitions with slots for interlocking and a lid design that prevents spills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the openings between chambers are made narrow to slow down flow rate and prevent re-suspension, then separation efficiency is improved, but device complexity increases due to precise opening positioning requirements
Solution Approach 1:
The partition walls are segmented with multiple openings at different heights, allowing the system to achieve flow control through distributed openings rather than requiring precise positioning of single large openings. This segmentation reduces the complexity of individual opening positioning while maintaining overall flow rate control.
Solution Approach 2:
Different openings are positioned at different heights and locations on partition walls to create localized flow control zones. The first opening is positioned lower than the second opening, creating different flow characteristics in different chambers. This local differentiation allows each opening to be simpler in design while collectively achieving the desired flow rate reduction and separation efficiency.
2Reliability
If multiple partition walls are used to divide the container into chambers, then separation efficiency is improved, but ease of assembly deteriorates
Solution Approach 1:
The partition walls are designed as separate, modular components that can be assembled independently. Each partition wall with its openings can be manufactured separately and then assembled into the complete container system, making the assembly process easier while maintaining the multi-chamber structure necessary for separation efficiency.
Solution Approach 2:
Multiple partition walls are combined to form a complete set of dividing structures, with the openings strategically positioned across the partitions to create interconnected chambers. This merging of partition components achieves the necessary separation efficiency while the modular nature of the combined structure facilitates easier assembly compared to a monolithic design.
3Reliability
If the flow rate is slowed down through narrow openings, then suspended matter separation is improved, but liquid throughput decreases
Solution Approach 1:
The system divides the liquid flow path into multiple chambers with multiple openings at different heights. This segmentation allows parallel flow paths that collectively maintain higher throughput while individual openings remain narrow enough to slow down the flow and facilitate separation. The distributed opening arrangement provides multiple channels for liquid to flow through simultaneously.
Solution Approach 2:
Openings are positioned at different vertical heights rather than only at different horizontal locations. The first opening is positioned lower than the second opening, utilizing the vertical dimension to create different flow characteristics. This dimensional arrangement allows the system to maintain throughput while achieving flow rate control through the vertical positioning of openings at different heights.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the separation efficiency of suspended matter by maintaining a controlled flow rate and preventing re-suspension, allowing for effective pre-cleaning of liquids with up to 70% removal of suspended gypsum or clay residues, while simplifying the assembly process.
Implementation Method 1
the openings can be kept narrow so that they only have a small height and slow down the flow rate
Implementation Method 2
the suspended matter is deposited in each of the chambers
Implementation Method 3
there may be a back pressure as soon as the liquid is introduced into the container and the liquid is slowly introduced into the first chamber
Implementation Method 4
The container suitably has a lid which rests on the upper edges of the partitions. This prevents the liquid from spilling over the top edges of the partitions

AI summary
The invention relates to a device (10) for precipitating suspended materials from a liquid, in particular for precipitating gypsum from water, having a vessel (12) comprising a liquid inlet (22) and a liquid outlet (26), and subdivided into chambers (40, 42, 44, 46) that are in sequence in the flow direction by means of partitions (32, 34, 36, 38), wherein the liquid inlet (22) opens into a first of the chambers (40) and wherein the liquid outlet (26) opens into a last of the chambers (46). According to the invention, at least one part of the chambers (40, 42, 44, 46) and preferably every chamber (40, 42, 44, 46) communicates with the chamber (42, 44, 46) downstream thereof in the flow direction by means of an opening (54) in the partition (34, 36, 38) disposed between the chambers (40, 42, 44, 46), wherein the opening (54) extends at a distance from and parallel to an upper edge (48) of the partition (34, 36, 38), and each of the openings (54) is disposed at a greater distance from the vessel floor (15) than the opening (54) in the partition (36, 38) downstream thereof in the flow direction.
