Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impact reactors face challenges in achieving effective material separation and recycling, particularly for chemically reactive materials like accumulators, which require precise control of atmosphere and particle size separation to prevent chemical reactions and ensure safe processing.
Innovation Solution
The impact reactor design includes a cylindrical casing with a rotor equipped with impact elements, closable feed and removal openings for independent atmosphere control, and a deflector wheel system for precise particle and gas separation, allowing for variable speed settings and multiple deflector wheels to manage different particle sizes and gases effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemically reactive material is comminuted in an open impact reactor, then the comminution process can proceed, but chemical reactions may occur and safety risks increase
Solution Approach 1:
The impact reactor is equipped with closable feed opening and removal opening that enable the creation and maintenance of an inert atmosphere independent of ambient air. This allows chemically reactive material to be comminuted safely without chemical reactions, directly resolving the safety concern while managing the complexity through controlled atmosphere management
2Manufacturing precision
If material separation is performed without closable openings, then the structure remains simple, but particle size separation precision is insufficient
Solution Approach 1:
The removal opening is made closable with adjustable closing elements that can dynamically control the opening size and closure state. This dynamic control enables precise particle size separation by adjusting the opening dimensions to match specific particle size requirements, while the closable design maintains structural simplicity through a single adjustable mechanism
3Ease of operation
If the impact reactor operates with ambient air atmosphere, then operation is simple, but chemically reactive materials cannot be processed safely
Solution Approach 1:
The reactor enables operation with an inert atmosphere independent of ambient air through closable openings that can seal the reactor chamber. This allows chemically reactive materials to be processed safely by excluding reactive gases from the environment, while maintaining ease of operation through automated atmosphere control without requiring complex manual intervention
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
This design enables efficient separation and recycling of materials by maintaining an independent atmosphere, preventing chemical reactions, and effectively managing particle and gas discharge, particularly suitable for accumulators with residual charge, ensuring safe and efficient comminution and recycling processes.
Implementation Method 1
the material to be comminuted is comminuted by impact stress with a high momentum transfer by means of rotating impact elements
Implementation Method 2
The rotation of the deflector wheel accelerates the classifying air in the circumferential direction and also causes it to rotate. The particles are acted upon by centrifugal force, wherein particles above the separation limit are rejected and separated from the classifying air.
Implementation Method 3
A first removal opening can be disposed in the casing, wherein the first removal opening comprises a screen. Screens are classifying devices that are designed in a particularly simple manner and are particularly robust. By selecting the hole diameter, or mesh size, the particle sizes to be passed through can be defined.
