Offloading Vacuum Tank With Dual Conveyors for Precise Debris Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum systems for debris removal from excavation sites face challenges in efficiently transferring materials to high-ground containers and lack precision in offloading only a portion of the debris, especially when reuse or reclamation is necessary.
Innovation Solution
A vacuum system with an internal conveyor within the tank and an external conveyor outside the tank, combined with a blower and ground-facing outlet, allows for precise offloading of debris into containers positioned higher than the tank, using hydraulic actuators to control the external conveyor's position and a ground-facing second outlet for gravity-fed material discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tank is tipped to unload material with a door open, then material can be removed from the tank, but it becomes difficult to transfer material to containers positioned high off the ground and controlling partial offloading becomes difficult
Solution Approach 1:
The unloading mechanism is segmented into two independent outlets: a first outlet for general material removal and a second outlet specifically positioned for high-ground container transfer. This segmentation allows selective operation of each outlet for different unloading scenarios, enabling efficient transfer to high-ground containers while maintaining ease of operation for general material removal.
Solution Approach 2:
The second outlet is positioned at a different spatial dimension (higher position) compared to the first outlet, creating a vertical dimension for material transfer. This dimensional differentiation enables direct transfer of material to containers positioned high off the ground without requiring tank tipping, thus improving productivity while maintaining operational ease.
2Device complexity
If a single outlet is used for material removal, then the structure is simple, but precise offloading of only a portion of debris is difficult
Solution Approach 1:
The single outlet is segmented into two separate outlets with distinct functions: the first outlet for general material removal and the second outlet for precise partial offloading to high-ground containers. This segmentation enables precise control over which material is removed and where it is transferred, improving offloading control precision while maintaining relatively simple device complexity through independent outlet operation.
Solution Approach 2:
Each outlet is assigned a specific local function and positioning optimized for its purpose. The second outlet is locally positioned and configured specifically for transferring material to high-ground containers, enabling precise partial offloading. This local quality differentiation allows precise offloading control without significantly increasing overall device complexity.
3Adaptability or versatility
If material is transferred to high-ground containers, then reuse or reclamation becomes possible, but the existing door-and-tip configuration makes this difficult
Solution Approach 1:
The outlet system is segmented to include a second outlet specifically designed for transferring material to high-ground containers. This dedicated outlet enables material reuse and reclamation operations without requiring complex tank tipping maneuvers, thus improving adaptability for material reuse while maintaining ease of operation through direct transfer capability.
Solution Approach 2:
The second outlet creates a vertical transfer dimension that directly connects to high-ground container positions. This dimensional approach enables easy transfer of material to elevated containers, facilitating material reuse and reclamation operations without requiring complex operational sequences, thus improving both adaptability and ease of operation.

AI summary
An offloading vacuum system. The system has a tank to capture debris from an excavation site. The debris is pulled into the tank due to a blower pulling air into an attached hose. An internal conveyor within the tank conveys material to an offloading hub. The offloading hub has a ground-facing door which opens to deposit debris into an external conveyor. The external conveyor, when deployed, can move debris from below the tank to a dump container with a wall greater than a height of the tank.
