Radial Fan Suction Structure for Rail Particle Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile suction devices for machining processes, such as milling or grinding, are limited by the volume of their collection devices, which restricts processing duration due to the need for frequent emptying and recycling of particles.
Innovation Solution
A suction device comprising multiple radial fans with a fan wheel and a collection channel that forms a roller gap between adjacent fans, where particles are deformed and comminuted, increasing density and reducing volume, thereby extending processing duration without additional units or energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a collection device with sufficient volume is used to collect particles for extended processing, then processing duration is extended, but the device complexity and space requirements increase
Solution Approach 1:
The patent changes the physical state and density parameters of the collected particles by subjecting them to compression forces within the radial fan structure. The particles are pressed against the fan wheel and compressed, increasing their density and reducing their volume, thereby extending processing duration without requiring a larger collection device
Solution Approach 2:
The rotating fan wheel creates dynamic mechanical forces that act on the particles, including centrifugal forces and impact forces, which help to compact and densify the particle material in the collection space, effectively reducing the volume occupied by the collected particles
2Productivity
If particles are collected and stored in a defined space, then recycling efficiency is improved, but the processing duration is limited by the collection device volume
Solution Approach 1:
The patent applies compression to change the density parameter of collected particles, transforming them from a low-density to a high-density state. This parameter change allows more material to be stored in the same volume, extending processing duration while maintaining recycling efficiency
Solution Approach 2:
The patent extracts the compression and densification function from a separate processing stage and integrates it into the particle collection process itself. The radial fan structure performs both collection and compression functions simultaneously, eliminating the need for additional processing equipment
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 suction device effectively processes and transports particles, increasing the mass of material that can be handled within the collection device's volume, significantly extending the operating time by reducing the volume of particles and enhancing the recycling efficiency.
Implementation Method 1
Each radial fan has a suction opening for drawing in particles which are removed during processing
Implementation Method 2
The impact face faces the suction opening for radially redirecting the particles which strike the impact face
Implementation Method 3
using the rotational movement of the fan wheel alone, to supply a large portion of the particles contained in the fluid to be conveyed under the action of the inertia forces and dynamic forces

AI summary
A suction device includes a plurality of radial fans. Each respective radial fan has a suction opening for drawing in particles that are removed during processing, and an outlet opening for discharging the particles into a collection device. Each radial fan has a fan wheel driven in a rotationally movable manner about a rotation axis. The fan wheel has a circumferential face and an impact face. The impact face faces the suction opening for radially redirecting the particles that strike the impact face. The suction device further includes at least one collection channel circumferentially and partially surrounding the fan wheel of each respective radial fan. The circumferential faces of the fan wheels of adjacent radial fans delimit a roller gap. The collection channel opens in the roller gap.
