Solution Overview
Problem
Existing paper recycling systems face complexity and increased costs due to the need for spiral pipelines or screw feeders to generate swirling flows, which complicate apparatus configurations and require additional drive sources.
Innovation Solution
A swirling flow generation device comprising a first pipe with a first pipe axis, a second pipe with a different axis communicating downstream, and an airflow changing unit with an opening eccentric from the first pipe axis, which creates a swirling flow to disperse defibrated material uniformly in a drum with through-holes, simplifying the configuration and eliminating the need for additional drive sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a spiral pipeline is provided in the pipe to generate swirling flow, then the defibrated material is dispersed uniformly, but the apparatus configuration becomes complicated
Solution Approach 1:
The pipe is segmented into a first pipe and a second pipe with different axes, creating a bent configuration that generates swirling flow without requiring a spiral pipeline. This segmentation allows the gas flow to change direction and create rotation naturally
Solution Approach 2:
An airflow changing unit with an eccentric opening is introduced as an intermediary component to modify the gas flow. This unit creates a swirling flow pattern by redirecting the gas flow through its asymmetric opening, achieving uniform dispersion without complex spiral structures
2Manufacturing precision
If a screw feeder is provided in the pipe to generate swirling flow, then the defibrated material is dispersed uniformly, but it is necessary to install a drive source and the apparatus configuration becomes complicated
Solution Approach 1:
The mechanical screw feeder system is replaced with a pneumatic flow control system. The airflow changing unit uses gas flow dynamics and geometric configuration to generate swirling flow, eliminating the need for mechanical components and their drive sources
Solution Approach 2:
The invention uses pneumatic principles by utilizing gas flow through the bent pipe configuration and airflow changing unit to create swirling motion. This pneumatic approach replaces mechanical screw feeders and their motors, simplifying the apparatus while achieving the same dispersion effect

AI summary
A swirling flow generation device includes a first pipe having a first pipe axis and through which gas passes, a second pipe having a second pipe axis in a direction different from the first pipe axis and communicates with downstream of the first pipe, and an airflow changing unit provided in the first pipe and having an opening eccentric from the first pipe axis. A swirling flow is formed in the second pipe as the center of the airflow passed through the opening flows into the second pipe at a position that is eccentric from the second pipe axis.
