Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sponge abrasive blasting machines face issues with incomplete discharge of abrasive due to the use of screw rod propulsion structures, which fail to effectively deliver abrasive from the tank to the blasting hose, particularly around the tank's walls and corners.
Innovation Solution
An oscillator with a flat strip-shaped drive shaft and flexible stirring arms in spring structures, connected to the tank's side walls, is used to stir and vibrate the abrasive, ensuring thorough discharge through a motor-driven rotation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a screw rod propulsion structure is adopted to deliver sponge abrasive, then the structure is simple, but the discharge is incomplete and abrasive remains attached on the wall and corner of tank
Solution Approach 1:
The patent applies mechanical vibration through flexible stirring arms that vibrate during rotation to prevent sponge abrasive from adhering to the tank walls and corners. The vibration mechanism ensures complete discharge by continuously loosening and agitating the abrasive material, preventing it from becoming stuck in dead zones of the tank.
Solution Approach 2:
The patent transforms the static screw rod propulsion structure into a dynamic system with flexible stirring arms that can adapt their position and movement pattern. The stirring arms rotate and flex dynamically to reach all areas of the tank including corners and walls, ensuring complete abrasive discharge while maintaining structural simplicity.
2Productivity
If a screw rod propulsion structure is used, then the device is simple, but the sponge abrasive is not thoroughly delivered into the blast pipe
Solution Approach 1:
The flexible stirring arms incorporate vibration functionality that agitates the sponge abrasive during the discharge process. This vibration ensures thorough delivery by preventing the abrasive from becoming compacted or stuck, thereby improving both discharge thoroughness and operational smoothness simultaneously.
Solution Approach 2:
The patent changes the physical state and movement parameters of the stirring mechanism by introducing flexibility and vibration capabilities. This allows the stirring arms to adapt their movement pattern and contact force, ensuring smooth and thorough discharge of sponge abrasive into the blast pipe.
3Quantity of substance
If the sponge abrasive is placed in a tank, then the abrasive is contained, but the abrasive is not prone to flow out and into the blast pipe
Solution Approach 1:
The patent employs a dynamic stirring mechanism with flexible arms that rotate and flex to actively move sponge abrasive from the tank toward the blast pipe. This dynamic approach ensures complete delivery of the abrasive quantity while maintaining relatively simple device architecture through the use of flexible rather than rigid components.

AI summary
The present disclosure discloses an oscillator for stirring and vibration of sponge abrasive blast, and relates to the technical field of sponge abrasive blasting machines. To overcome the technical deficiencies of a screw rod propulsion structure adopted by an existing sponge abrasive blasting machine, the oscillator comprises a tank, a stirrer disposed in the tank and a power mechanism for driving the stirrer, wherein the stirrer comprises a drive shaft in a flat strip-shaped structure, an upper end of the drive shaft is in transmission connection with the power mechanism, a bottom end of the drive shaft is inserted into a discharge channel of the tank, and each side wall of the drive shaft is connected with more than two flexible stirring arms in spring structures. With the adoption of the drive shaft in the flat strip-shaped structure, a part of an airflow in an airflow pipeline can be intermittently introduced into the tank to blow off a sponge abrasive stuck in corner positions during the rotation of the drive shaft, and meanwhile, under the stirring and vibration of more than two flexible stirring arms in the spring structures connected to each side wall of the drive shaft, the discharging is smooth and thorough.
