Solution Overview
Problem
Existing large format dust collection systems face challenges in transportation and assembly due to large components and non-standard parts, and require frequent maintenance of chain drive mechanisms and prone suction nozzle components, leading to increased operational costs.
Innovation Solution
A modular dust collection system with a support frame divided into interconnected octagonal sections, featuring a rotating and reciprocating filter cleaning assembly with fewer wear components and a direct rotational drive, allowing for easier assembly and reduced maintenance, and suction nozzles with flexible sections to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If large format dust collection systems are used, then filtration capacity is improved, but transportation and assembly become difficult due to large components and non-standard parts
Solution Approach 1:
The dust collection system is divided into multiple modular sections, each containing a drum filter, support frame, and cleaner assembly. These standardized sections can be manufactured separately, transported easily, and assembled on-site to create large-scale filtration systems, resolving the contradiction between large filtration capacity and ease of transportation/assembly.
2Speed
If chain drive mechanisms are used in filter cleaning systems, then rotational movement is achieved, but maintenance frequency increases due to wear components
Solution Approach 1:
The patent replaces chain drive mechanisms with a belt drive system for rotating the drum filter. The belt drive has fewer wear components compared to chain drives, reducing maintenance frequency while still achieving the required rotational speed for the cleaner assembly to effectively remove dust from the filter media.
3Productivity
If rigid suction nozzles are used, then cleaning efficiency is maintained, but durability decreases due to prone components
Solution Approach 1:
The suction nozzles are designed with flexible sections that allow the rigid cleaning components to maintain their structural integrity and cleaning efficiency while the flexible portions absorb mechanical stresses and prevent damage from contact with the drum filter surface, thereby improving durability without sacrificing cleaning performance.
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 modular design simplifies installation, reduces maintenance needs, and lowers operational costs by allowing prefabricated sections and fewer wear components, while the flexible nozzles enhance durability and cleaning efficiency.
Implementation Method 1
Rotating and reciprocating suction nozzles inside of the drum continuously vacuum dust and waste from the interior surface of the filter media.
Implementation Method 2
suction nozzles with flexible sections to prevent damage

AI summary
A support frame for dust collection system including a drum filter and a filter cleaning system is disclosed where the frame includes a plurality of octagonal supports spaced apart from each other in an axial direction defining an octagon-shaped peripheral profile. A plurality of axial members extend between adjacent octagonal supports, and end covers are secured to the frame members with each cover including a first inlet opening and a second inlet opening. The support frame may be used in a modular dust collection with a plurality of modular segments of filter media segments secured to the frame and a filter cleaner segments corresponding to the filter media segments.
