Cyclone Array Dust Removal System for Portable Construction Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust removal systems in the construction industry, such as wet/dry vacuums, are inadequate for managing dust from cutting building materials like fiber cement, as they fail to meet safety standards, are cumbersome, and have inefficient filter systems that quickly become clogged.
Innovation Solution
A dust separation device with a cyclone array and mesh screen that separates dust from air in multiple stages, including a pre-filtration stage, cyclonic separators, and a final filtration stage, designed to be portable and efficient in removing various particle sizes, and can be coupled with a variety of receptacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wet/dry vacuum cleaners are used for dust removal, then dust can be collected, but the device becomes large, heavy, and inconvenient to transport
Solution Approach 1:
The dust removal system is divided into separate functional modules: a cyclone array for dust separation, a pump for air movement, and a collection container. This segmentation allows the system to achieve effective dust collection while maintaining a more compact and manageable form factor compared to traditional wet/dry vacuums.
Solution Approach 2:
The system uses a pump to create pneumatic flow that moves dust-laden air through the cyclone array. This pneumatic mechanism enables effective dust collection without requiring the heavy-duty motor and large capacity design of traditional wet/dry vacuums, thereby reducing overall device weight and improving portability.
2Reliability
If filters are used as primary dust removal method, then dust can be captured, but filters quickly become clogged and require frequent maintenance
Solution Approach 1:
The cyclone array performs preliminary dust separation before air reaches the filter. By removing the bulk of dust particles through centrifugal force in the cyclones, the system prevents filters from becoming quickly clogged, thereby reducing maintenance frequency and extending filter life.
Solution Approach 2:
The system replaces the primary mechanical filtration approach with a pneumatic centrifugal separation mechanism (cyclone array). This substitution allows dust to be removed through aerodynamic forces rather than mechanical filtering, significantly reducing the burden on filters and decreasing maintenance requirements.
3Reliability
If traditional vacuum systems are used, then dust can be removed, but they fail to meet current safety requirements for dust exposure
Solution Approach 1:
The dust removal process is segmented into multiple stages: initial dust-laden air intake, cyclonic separation in the array, and final filtration. This multi-stage approach ensures more thorough dust removal and reduces dust exposure to acceptable safety levels, meeting OSHA requirements that traditional single-stage systems fail to achieve.
Solution Approach 2:
The system employs a pump that provides sufficient airflow to ensure complete dust capture and removal. By providing more than the minimum required airflow and using multiple cyclones in parallel, the system ensures that dust exposure levels fall well below OSHA limits, exceeding the performance of traditional vacuum systems.

AI summary
A compact dust removal system that can be mounted on a substantially rigid receptacle, such as a pail, found at construction sites. The compact dust removal system includes an array of cyclonic separators of different sizes disposed within a mesh filter. The system can be mountable to a pail such that an initial dust removal stage occurs by inertial separation along the interior surface of the pail. The system further includes a cyclone inlet manifold configured to distribute dust-laden air among the cyclonic separators at least partially based on the size of dust particles within the dust-laden air.
