Rotating Sieve Cover Structure to Prevent Edge Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing separation device suffers from filtration products accumulating at the outer peripheral edge of the mesh disk due to centrifugal force or airflow, leading to clogging and rotation failure.
Innovation Solution
A separation device with a rotating sieve and a cover member that includes a mesh, a wall portion, and an upper frame, where the cover member has an outer portion, an inner portion, and a bent portion to follow the relative position change between the sieve and the frame, preventing filtration products from moving outward and maintaining stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mesh disk rotates at high speed for efficient separation, then productivity is improved, but filtration product accumulates at the outer peripheral edge due to centrifugal force causing clogging and rotation failure
Solution Approach 1:
The harmful accumulation of filtration product at the outer peripheral edge is extracted and removed by the cover member, which collects and directs the accumulated material away from the gap between the mesh disk and support portion, preventing clogging and maintaining reliable rotation during high-speed operation
Solution Approach 2:
The cover member acts as an intermediary element between the mesh disk and the external environment, intercepting and managing the filtration product before it can cause harm to the rotation mechanism, thus mediating between the centrifugal force effects and the rotation stability
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 device effectively prevents clogging at the outer peripheral edge, ensuring stable operation and efficient separation of filtration products from foreign matter.
Implementation Method 1
filtration product accumulating on the front surface of the mesh disk moves to an outer peripheral edge of the mesh disk due to a centrifugal force

AI summary
A separation device includes a rotating sieve including a mesh, a wall portion that defines a space in which the sieve rotates, a cover member that covers a gap between an annular portion on an outer periphery of the sieve and the wall portion, and an upper frame outside the space in which the sieve rotates, the cover member has an outer portion along the upper frame, an inner portion along the annular portion, and a bent portion between the outer portion and the inner portion, and the bent portion causes the inner portion to follow a change in a relative position between the sieve and the upper frame.
