Intermediate Container Bypass Channel for Pressure-Managed Waste Conveying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic waste conveying systems face issues with undesired material displacement and mixing due to pressure differences and leakage air, requiring a separate discharge valve and deep excavation for intermediate containers, especially in rocky areas.
Innovation Solution
A bypass channel is integrated into the intermediate container to compensate for volume changes and leakage air, eliminating the need for a separate discharge valve and allowing for efficient material displacement without mixing categories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate discharge valve and deep excavation pit are used for intermediate containers, then material displacement control is improved, but installation complexity and cost increase
Solution Approach 1:
The bypass channel is integrated directly into the intermediate container structure, merging the function of material displacement control with the container itself. This eliminates the need for separate discharge valves and complex excavation pits, while maintaining reliable control over material displacement through the bypass channel mechanism.
2Ease of manufacture
If intermediate containers are installed at shallow depths, then excavation cost is reduced, but prevention of undesired material displacement becomes difficult
Solution Approach 1:
The bypass channel acts as an intermediary mechanism within the intermediate container, providing controlled pathways for material displacement. This allows shallow installation depths with reduced excavation costs while maintaining reliable prevention of undesired material displacement through the regulated bypass channel operation.
3Device complexity
If bypass channel is integrated into intermediate container, then device complexity is reduced, but control over leakage air and pressure differences becomes more challenging
Solution Approach 1:
The bypass channel is designed to automatically respond to pressure differences and leakage air conditions within the intermediate container. The integrated structure enables self-regulating operation where the bypass channel opens or closes based on internal pressure conditions, eliminating the need for complex external control mechanisms while maintaining effective pressure and leakage air management.

Function Achieved in This Case
The solution prevents undesired material displacement and mixing, reduces installation depth requirements, and enhances operational reliability by managing pressure differences and leakage air effectively.
Implementation Method 1
compensating a change in volume resulting from a pressure difference of the intermediate container
Implementation Method 2
conducting possible leakage air of the input point into the material conveying pipe past the material
Implementation Method 3
a partial-vacuum apparatus is used to bring about a pressure difference, in which apparatus negative pressure is brought about in the material conveying pipe
Implementation Method 4
by bringing about compression in size in at least a part of the material being conveyed, by means of an impediment arranged between the conveying pipe and the material to be handled, or against the impediment

AI summary
Method for compensating a change in volume caused by a pressure difference of the intermediate container of an input point of a pneumatic pipe collection system for material and/or for preventing undesired material displacement from the intermediate container. In the method a bypass channel (17) is arranged in the channel section (20, 21, 22) formed by the intermediate container of an input point for compensating a change in volume resulting from the pressure difference of the pressures of different magnitudes possibly acting on different sides of the material (w) and/or for preventing undesired material displacement from the channel section (20, 21, 22) into the material conveying pipe (100). The invention also relates to an apparatus and to a wastes conveying system.
