Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic conveyor systems are inefficient due to weak suction pressure and design limitations, making them unsuitable for high-volume dust collection applications, as they require excessive energy and are prone to particle deformation or breakage.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a typical blower with rotating fan blades is used to create suction, then particles can be conveyed, but the fan blades deform or break over time, lowering the suction pressure
Solution Approach 1:
The patent removes the rotating fan blade component entirely from the blower system. Instead of using a mechanical rotating element, the invention employs a stationary vortex member with spiral blades that redirect airflow to create rotational motion and suction pressure without any moving parts, thereby eliminating wear and deformation issues
Solution Approach 2:
The patent replaces the mechanical rotating fan blade system with a stationary vortex member that uses fluid dynamics principles. The spiral blades of the vortex member redirect airflow to generate rotational motion and suction pressure through aerodynamic forces rather than mechanical rotation, eliminating the need for moving parts
2Quantity of substance
If compressed air is used to convey particles, then particles can be transported, but the particles must travel within the stream of compressed air, lowering the volume of particles that can be sucked
Solution Approach 1:
The patent divides the airflow into two distinct functional zones: an outer annular flow path for compressed air that provides suction pressure, and an inner core flow path for particle-laden air that enters through the center. This segmentation allows both functions to occur simultaneously without interfering with each other, maximizing both particle volume and conveyance efficiency
Solution Approach 2:
The patent transitions from a single-dimensional linear airflow to a three-dimensional vortex flow structure. The compressed air flows in an outer annular region while particles are conveyed through the inner core, utilizing radial and axial components of flow to increase the volume capacity for particle transport while maintaining high conveyance efficiency
3Use of energy by moving object
If the efficiency of the filtering means is low, then more energy and suction pressure is required by the blower
Solution Approach 1:
The patent changes the fundamental operating parameters of the blower by eliminating moving parts and implementing a stationary vortex member design. This structural parameter change enables the system to maintain high suction pressure and energy efficiency simultaneously, as the stationary design prevents energy losses associated with mechanical wear and deformation while the vortex geometry optimizes airflow patterns for efficient particle separation

AI summary
The vortex pneumatic conveyance apparatus of the present application creates a vortex from blown and/or pressurized air rotating along the inner wall of an outlet tube to convey particles through a vacuum created within the center of the outlet tube at a relatively high flow rate and pressure. Without the blown and/or pressurized air molecules taking up space and colliding with the particles in the center of the outlet tube and because of the strong suction created by the vortex of air rotating along the inner wall of the outlet tube, the efficiency of the vortex pneumatic conveyance apparatus of this application is improved relative to well-known pneumatic conveyors in which air merely pushes the particles within an outlet tube.
