Solid Particle Flow Path Layout to Prevent Delivery Pipe Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow rate adjustment devices for solid particles are prone to clogging due to foreign matter larger than the particles, which causes blockages in the delivery pipe.
Innovation Solution
A flow rate adjustment device with a storage tank, delivery pipe, through hole, inclined portion, and foreign-matter receiving portion is designed to guide solid particles into the delivery pipe while diverting foreign matter into a recessed area, using inclined surfaces to prevent clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solid particles are delivered through the delivery pipe from the storage tank, then the flow rate of solid particles can be adjusted, but foreign matter larger than the solid particles causes clogging of the delivery pipe
Solution Approach 1:
The delivery system is segmented into multiple pathways: through-holes for solid particles and a foreign-matter receiving portion for larger foreign matter. This segmentation allows different sized objects to be directed to different destinations, preventing clogging while maintaining particle flow
Solution Approach 2:
Foreign matter is extracted from the solid particle stream by directing it into the foreign-matter receiving portion through the inclined portion. This separates the harmful foreign matter from the useful solid particles before they can clog the delivery pipe
2Ease of operation
If the delivery pipe is designed to handle solid particles, then particle flow is enabled, but foreign matter blockages the flow path
Solution Approach 1:
The inclined portion acts as an intermediary structure that redirects foreign matter away from the delivery pipe entrance. It mediates between the storage tank contents and the delivery pipe, filtering out foreign matter before it can block the flow path
Solution Approach 2:
The foreign-matter receiving portion is positioned in a different spatial dimension (recessed in the bottom surface) from the delivery pipe entrance. This dimensional separation allows foreign matter to be diverted into a separate space, preventing blockages
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 suppresses clogging of the delivery pipe by guiding foreign matter into a separate receptacle, ensuring smooth flow of solid particles.
Implementation Method 1
an inclined portion, which is provided at an upper end of the delivery pipe, and is inclined downward toward an inner wall of the storage tank

AI summary
Provided is a flow rate adjustment device, including: a storage tank that allows solid particles to be stored in the storage tank; a delivery pipe, which penetrates a bottom surface of the storage tank, and has an upper end arranged in the storage tank; a through hole, which penetrates a side surface of the delivery pipe, and guides the solid particles stored in the storage tank into the delivery pipe; an inclined portion, which is provided at an upper end of the delivery pipe, and is inclined downward toward an inner wall of the storage tank; and a foreign-matter receiving portion, which is formed in a region of the bottom surface of the storage tank, the region facing an edge of a lower end of the inclined portion, and which is recessed downward.
