Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collectors are too large and cumbersome, requiring a more compact design to efficiently collect welding fumes while maintaining effective filtration and recovery efficiency.
Innovation Solution
A compact dust collector design featuring a tank with a bottleneck structure and separate towers for air flow and filtration, utilizing a mist generator to enhance particle collection and filtration efficiency, and incorporating filters to minimize waste space and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional dust collector design is used with separate spray chamber and filter housing chambers, then effective welding fume collection and filtration is achieved, but the equipment size and weight become excessively large
Solution Approach 1:
The patent combines the spray chamber and filter housing chamber into a single integrated tank structure. The filter is housed within the tank, and the spray nozzle is positioned inside the tank to spray water directly onto the welding fumes. This merging of previously separate components achieves effective fume collection and filtration while significantly reducing equipment size and weight.

If a conventional dust collector design is used with separate spray chamber and filter housing chambers, then effective welding fume collection and filtration is achieved, but the equipment occupies excessive space
Solution Approach 1:

The filter is housed within the tank, and the spray nozzle is positioned inside the tank to spray water directly onto the welding fumes. This merging of previously separate components achieves effective fume collection and filtration while significantly reducing equipment size and weight.
Solution Approach 2:
The filter housing is nested within the tank structure, with the filter positioned inside the tank. The spray nozzle is also positioned inside the tank, creating a nested arrangement where multiple functional components are housed within a single compact structure, minimizing the overall equipment footprint.
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 compact design achieves improved recovery efficiency of welding fumes, reducing environmental impact by effectively collecting and extinguishing fumes within the tank, and allowing for easier movement and reduced equipment size and cost.
Implementation Method 1
a mist generator configured to generate mist in the first tower
Implementation Method 2
Air containing welding fumes moves from the top to the bottom in the spray chamber, then moves laterally on the stored water
Implementation Method 3
collects and extinguishing fumes within the tank

AI summary
A dust collector that collects welding fumes includes: a tank that stores water in a non-full state; a first tower that stands upright from an upper surface of the tank, and is configured to receive air containing the welding fumes from an upper part of the first tower and to guide the air to the tank; a second tower that stands upright from the upper surface of the tank, and is configured such that air discharged from the tank passes through the second tower; a bottleneck structure portion in which a vertically intermediate part of the first tower is narrowed; a mist generator configured to generate mist in the first tower; and a filter housed in the second tower.
