Flat Channel Classifier Pipeline for Particle Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline designs with round cross-sections face challenges in cleaning efficiency, particle flow obstruction, and clogging due to the use of struts and flange sockets, which hinder multi-stage cleaning and particle separation.
Innovation Solution
A pipeline design with a flat cross-section that allows direct attachment of interior components to the housing walls, reducing flow obstruction and enabling easier cleaning and multi-stage processing, along with a conical inner body to enhance flow orientation and separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a round pipeline with cone-shaped inner body is used, then the structure can be attached to housing walls, but the struts and flange sockets obstruct particle flow and reduce cleaning efficiency
Solution Approach 1:
The patent transitions from a symmetric round pipeline cross-section to an asymmetric flat channel cross-section. This asymmetry allows the inner body to be attached directly to the housing walls without requiring struts that would obstruct the particle flow path, thereby eliminating the contradiction between ease of manufacture and cleaning efficiency.
Solution Approach 2:
The invention changes the dimensional configuration from a round cross-section to a flat channel cross-section. This dimensional change provides a different spatial arrangement where the inner body can be mounted on the housing walls without interfering with the particle flow in the ring channel, resolving the conflict between attachment ease and cleaning performance.
2Stability of the object's composition
If struts are used to attach the inner body, then the structure is stable, but the struts form obstacles to particle flow and cause injection grain formation
Solution Approach 1:
The patent extracts and removes the struts from the system by changing to a flat channel configuration where the inner body attaches directly to the housing walls. This elimination of struts removes the source of injection grain formation while maintaining structural stability through the direct wall attachment design.
3Device complexity
If a round cross-section pipeline is used, then the structure is simple, but multi-stage cleaning cannot be easily implemented and clogging cannot be effectively dissolved
Solution Approach 1:
The asymmetric flat channel cross-section enables multi-stage cleaning configurations that cannot be achieved in a symmetric round pipeline. The flat geometry allows for multiple cleaning stages to be arranged in series without the structural constraints of a round section, while still maintaining relative structural simplicity.

AI summary
Method for separating fine particles (29) from granular bulk materials conveyed as a product stream (18) in a pipeline (2) by means of air conveying or dune conveying, wherein the product stream (18) is radially spread at the inlet side of a classifier (1, 1a) integrated airtight in the pipeline (2) and is permeated there in the region of a cleaning plane (16, 16') by a cleaning air stream (9) flowing at an angle to the direction of the spread product stream (18), which deflects the lighter particles, threads, nests, dust or the like carried in the product stream (18) from the trajectory of the heavier granular particles (28) and conveys them into a collection chamber (17) through which the cleaning air (9) flows, wherein the classifier is designed as a flat channel classifier (1, 1a) whose inlet-side product stream (3, 18) is directed onto at least one flat cross-section is spread open.
