Rotating Screen Centrifugal Separator to Prevent Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing centrifugal separators used in machine tools for cleaning ventilated mixtures of gas, liquid, and solid particles are prone to clogging, reducing their service life and requiring frequent maintenance.
Innovation Solution
A separator arrangement with a rotating screen member and centrifugal separator, where the screen member with through holes pre-filters larger particles before they reach the centrifugal separator, reducing clogging and increasing the separator's service life by allowing self-cleaning of the screen member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centrifugal separator is used to clean ventilated mixture from a machine tool, then cleaning efficiency is improved, but the separator is prone to clogging which reduces service life
Solution Approach 1:
A pre-separation chamber is introduced before the centrifugal separator to perform preliminary separation of the ventilated mixture. This preliminary action removes a portion of particles before they enter the centrifugal separator, reducing the load and preventing clogging, thereby extending service life while maintaining cleaning efficiency
Solution Approach 2:
The separation system is divided into multiple stages: a pre-separation chamber for initial particle removal and a centrifugal separator for final cleaning. This segmentation distributes the separation load across different components, preventing any single component from becoming overloaded and clogged, thus improving both cleaning efficiency and service life
2Reliability
If a centrifugal separator is used to clean ventilated mixture, then particle removal is improved, but frequent maintenance is required due to clogging
Solution Approach 1:
The pre-separation chamber performs preliminary particle removal before the mixture enters the centrifugal separator. This reduces the amount of particles that would otherwise accumulate in the separator, decreasing maintenance frequency while maintaining effective particle removal capability
Solution Approach 2:
The pre-separation chamber acts as an intermediary component between the ventilated mixture source and the centrifugal separator. It mediates the particle removal process by handling the initial separation load, thereby protecting the centrifugal separator from excessive particle accumulation and reducing maintenance requirements
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
The solution effectively prevents larger particles from reaching the centrifugal separator, reducing clogging and maintenance needs, thereby extending the service life of the separator and maintaining efficient operation.
Implementation Method 1
a screen member (40) being provided with through holes (42), wherein a flow path through the separator arrangement (10) leads in a direction through the through holes (42) to the rotor inlet (28)
Implementation Method 2
a centrifugal separator, wherein the centrifugal separator comprises a separator rotor (20) arranged in the stationary housing (14)
Implementation Method 3
since the drive arrangement is arranged for rotating the screen member (40) about the rotational axis (22) - at least part of the particles that have been prefiltered by the screen member (40) from the mixture will loosen from the screen member (40)
