Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shot processing machines face challenges in accurately separating recovered blast material from foreign matter without enlarging the machine size, as they often rely on vibration sifters which increase machine size and efficiency limitations.
Innovation Solution
A shot processing machine incorporating an air sorting mechanism with a freefall zone, dispersion rods, and a settling chamber to separate foreign matter from blast material using upward air currents, along with a distribution system to optimize blast material supply and reduce machine enlargement, and a conveyor system for uniform workpiece processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vibration sifter is used to separate foreign matter from blast material, then separation function is achieved, but machine size becomes enlarged
Solution Approach 1:
The patent replaces the mechanical vibration sifter system with a pneumatic classification system. Air currents are used to classify and separate foreign matter from blast material based on density and aerodynamic properties, eliminating the need for mechanical vibrating components and significantly reducing machine size while maintaining effective separation functionality.
Solution Approach 2:
The invention employs pneumatic principles by introducing air currents into the blast material stream. The air flow carries lighter foreign matter particles differently from heavier blast material, achieving separation through pneumatic classification rather than mechanical vibration, thus avoiding the size penalty of traditional vibration sifters.
2Measurement precision
If blast material is allowed to fall freely with upward air current for separation, then sorting accuracy is improved, but separation time increases
Solution Approach 1:
The patent implements a controlled freefall process where blast material is allowed to fall only for the necessary duration to achieve adequate separation, rather than excessive fall time. The system optimizes the balance between fall distance and separation effectiveness, providing sufficient exposure to air currents for accurate sorting while minimizing unnecessary time loss.

AI summary
Provided is a shot peening device with which recovered projection material and foreign bodies can be more precisely separated while inhibiting an increase in the size of the device. The shot peening device is provided with: a projector (42) which projects projection material onto a workpiece (W); recovery mechanisms (52, 54) which recover the projection material projected by the projector; and a wind power sorting mechanism (62) in which recovered projection material is allowed to fall freely while an upward air current is applied to the recovered projection material, and foreign bodies included in the recovered projection material are separated from the recovered projection material.
