Chute Tube Triangular Groove for Particle Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chute tubes for particle transfer often cause damage to particles and generate dust due to step formations on their surfaces, especially when transferring softer particles, and fail to efficiently distribute or classify particles effectively.
Innovation Solution
A chute tube system comprising a charging chute, an intermediate chute tube with a groove formed by two inclined surfaces without steps, and a discharging chute, where the intermediate chute tube is connected in a slanting direction, allowing particles to flow through a triangular cross-sectional groove for concentrated distribution or classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If steps are formed on the chute tube surface to improve particle flow control, then particle transfer efficiency is improved, but particle damage and dust generation increase
Solution Approach 1:
The invention removes the harmful steps from the chute tube surface and replaces them with a smooth grooved structure. The groove is formed by combining an inclined surface with a curved surface, eliminating the corner surfaces that cause particle damage while maintaining flow control functionality.
Solution Approach 2:
The invention replaces sharp corner surfaces with curved surfaces. The groove is defined by an inclined surface transitioning to a curved surface, which eliminates abrupt corners and reduces mechanical stress on particles during transfer, thereby preventing damage and dust generation.
2Ease of manufacture
If a simple chute tube structure is used, then manufacturing cost is reduced, but particle distribution and classification performance deteriorates
Solution Approach 1:
The invention applies a localized groove structure at the critical flow control section of the chute tube, rather than complicating the entire structure. The groove is formed by combining an inclined surface with a curved surface, providing enhanced distribution and classification performance while maintaining overall structural simplicity and ease of manufacture.
3Manufacturing precision
If particles are transferred through a narrow flow path, then distribution precision is improved, but friction and particle wear increase
Solution Approach 1:
The invention uses a curved surface in the groove design to eliminate sharp corners and reduce friction. The curved transition from the inclined surface to the curved surface creates a smooth flow path that maintains narrow flow for precise distribution while reducing mechanical friction and wear on particles.
