Pneumatic Granule Ejection Replacing High-Speed Rotors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ejecting devices require high-speed rotation of rotors to forcefully eject granules, which can lead to granules getting stuck and causing operation failures due to collision with the inner surface, potentially damaging the granules or stopping the rotor.
Innovation Solution
An ejecting device utilizing a cylinder tube with a piston and a gas supply and discharge mechanism that compresses gas internally and forcefully ejects it to blow off granules, eliminating the need for high-speed rotor rotation and reducing the risk of granule sticking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a rotor rotates at high speed to forcefully eject granules, then the ejection force is improved, but granules may get stuck between the blade tip and the inner surface of the cylindrical guide, causing operation failures
Solution Approach 1:
The patent replaces the high-speed rotating rotor blade mechanism with a pneumatic ejection system. Compressed gas is supplied into the cylinder tube to move the piston, which then forcefully ejects the compressed gas through the ejector to blow off granules. This substitution eliminates the mechanical contact between rotating blades and granules, preventing granules from getting stuck while maintaining effective ejection force.
Solution Approach 2:
The patent employs a pneumatic system where compressed gas is used as the working medium. The gas supply and discharge means supplies compressed gas into the cylinder tube, the piston converts this pressure into linear motion, and the ejector directs the compressed gas to blow off granules. This pneumatic approach provides reliable granule ejection without the mechanical sticking problems associated with high-speed rotating blades.
2Productivity
If a rotor rotates at high speed to eject granules, then the ejection capability is improved, but the device complexity increases due to the need for high-speed rotation mechanism
Solution Approach 1:
The patent replaces the complex high-speed rotor rotation mechanism with a simpler pneumatic system. Instead of requiring a high-speed motor and rotating blade assembly, the invention uses a gas supply and discharge means to supply compressed gas, a piston to convert pressure into motion, and an ejector to direct the gas flow. This substitution maintains effective granule ejection capability while significantly reducing mechanical complexity.
Solution Approach 2:
The patent extracts the essential function of granule ejection from the complex rotating rotor system and implements it through a simplified pneumatic mechanism. By separating the ejection function from the high-speed rotation requirement, the system achieves the same productivity goal with a much simpler device structure.
3Productivity
If blades forcefully eject granules by rotating at high speed, then the ejection effectiveness is improved, but granules may be crushed or stuck, causing operation failures
Solution Approach 1:
The patent replaces the mechanical blade impact ejection method with a pneumatic blow-off method. Compressed gas is supplied through the cylinder tube and ejector to blow off granules without direct mechanical contact. This eliminates the harmful effects of blade impact that can crush granules or cause them to get stuck between the blade tip and guide surface, while maintaining effective ejection.
Solution Approach 2:
The patent introduces compressed gas as an intermediary medium between the piston and the granules. Instead of direct mechanical contact between the piston/blade and granules, the compressed gas serves as the medium that transfers the ejection force to the granules, blowing them off without causing damage or sticking.
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 device effectively ejects granules without the risk of sticking, ensuring smooth operation by using compressed gas to propel the granules, thus preventing operation failures.
Implementation Method 1
the gas supply and discharge means supplies gas into the internal space of the cylinder tube to compress gas in the internal space
Implementation Method 2
The compressed gas presses the piston in such a direction as to close the ejector
Implementation Method 3
the ejector to forcefully eject compressed gas out of the cylinder tube for the gas to blow off a granule

AI summary
There has been a demand for a simply configured ejecting device capable of ejecting a granule suitably without the risk of, for example, the granule being stuck to cause an operation failure. An ejecting device includes: a cylinder tube 20; a piston 21 slidable in the cylinder tube 20; and a gas supply and discharge means 22 switchable between a supply mode, in which the gas supply and discharge means 22 supplies gas into an internal space of the cylinder tube 20, and an open mode, in which the gas supply and discharge means 22 exposes the internal space to outside; and an ejector 23 configured to, in response to a movement of the piston 21, eject gas out of the cylinder tube 20 which gas has been supplied into the internal space and compressed.
