Spiral Separator Partition Wall Design for Sludge Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spiral separators are less suitable for separating mixtures containing sand or smaller rock debris, as they do not effectively handle two- or three-phase mixtures with particles, leading to inefficient separation and cleaning performance.
Innovation Solution
The separator is designed with a funnel-shaped lower area and a spiral partition wall that extends deep into the sludge settling space, featuring conically arranged windings with a smaller spiral radius in lower regions, and incorporates 3x 6 divided pipe bend packages to improve flow and separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional spiral separator design is used, then the structure is simple and easy to manufacture, but the separation efficiency for two- or three-phase mixtures containing sand or rock debris is insufficient
Solution Approach 1:
The separator is divided into distinct functional zones: an upper mixture separation chamber and a lower sludge settling chamber (trichterförmiger Abscheidebereich). The partition wall is segmented into multiple spiral turns that guide flow through different separation stages, with each zone handling specific separation tasks to improve overall efficiency for complex mixtures.
Solution Approach 2:
The partition wall extends vertically into the sludge settling chamber with its inner turn reaching deeper than the outer turn, creating a three-dimensional spiral flow path. This vertical extension into the lower chamber adds a depth dimension to the separation process, enabling effective handling of settleable substances and particles that conventional horizontal-only designs cannot address.
2Productivity
If the partition wall extends deeper into the separating tank, then the separation path is lengthened and separation efficiency is improved, but the device complexity increases
Solution Approach 1:
The partition wall is designed as a continuous spiral curve that winds around the collector axis, with its inner turn extending deeper into the sludge settling chamber than the outer turn. This curved, spiral configuration naturally lengthens the flow path and separation distance without requiring additional straight sections or complex mechanical components, achieving enhanced separation efficiency through geometric optimization.
3Manufacturing precision
If the funnel-shaped design is implemented, then drainage and separation of oil and particles are improved, but the manufacturing complexity increases
Solution Approach 1:
The lower area of the separating tank is designed with a funnel shape (trichterförmig), gradually narrowing toward the bottom to concentrate flow and enhance separation of oil and particles. This geometric parameter change optimizes fluid dynamics and separation efficiency while remaining manufacturable using standard fabrication techniques for conical or funnel-shaped vessels.
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 drainage and separation of oil and particles, achieving improved cleaning performance and efficient separation of two-phase mixtures with a light liquid and sludge portion, as well as single-phase mixtures with a smaller light liquid and larger heavy liquid portion, such as oil-contaminated water.
Implementation Method 1
one achieves a smoother surface and smoother and intensified mechanisms - centrifugal for particles and centripetal for light substances
Implementation Method 2
The sludge settling chamber is located below the mixture separator and light liquid collector, with the inner turn of the partition wall being guided deeper into the separating tank than the outer turn

AI summary
A separation pool (12) and an outlet tube collect the light liquid and slurry at an inlet tube (14) for separating the multi-phase mixture. The mixture is passed into a mixed racer and light liquid collectors (20). Heavy liquid and sludge are passed from mixed racer and heavy liquid collector. A partition (4) at mixed racer and light liquid collector, is extended from a wall (3) of mixed racer. An inner spiral portion of intermediate space is extended to sludge removal system (B), where inner depth of partition is more than outer convolution depth of the pool.
