Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional extrusion separation devices are used, then the basic separation function is achieved, but material sticking occurs during rotation of mechanisms, resulting in inability to operate continuously and low efficiency
Solution Approach 1:
The feed pusher assembly front end is designed with an arc shape smaller than a semi-circle, creating a cylindrical pre-compression chamber. This curved geometry prevents material sticking by avoiding sharp corners and flat surfaces where waste material could accumulate and adhere during the extrusion process, enabling continuous operation without interruption.
Solution Approach 2:
The device is divided into distinct functional modules: feed pusher assembly, feed box assembly, extrusion and discharge assembly, main extrusion guiding assembly, and anti-extrusion guiding assembly. Each module operates independently with specific functions, allowing the system to maintain continuous operation by segmenting the extrusion process into controlled stages that prevent material sticking.
2Manufacturing precision
If existing extrusion separation devices are used, then wet-component materials are processed, but impurities remain in the processed materials
Solution Approach 1:
The purification device is integrated with the extrusion separation device body, combining the extrusion separation function and purification function into a single unified system. The purification device includes a material trough, sieve plate, screw shaft, motor, and reduction box, which work together to separate and purify wet-component materials while maintaining compact device structure.
Solution Approach 2:
The sieve plate is provided with a plurality of through holes that allow separation of wet-component materials from impurities. The porous structure of the sieve plate enables efficient purification by allowing passage of separated materials while retaining impurities, achieving high purification quality without requiring overly complex device structures.
3Stress or pressure
If the feed pusher assembly front end has a semi-circular shape, then the structure is simple, but the compression ratio is insufficient
Solution Approach 1:
The feed pusher assembly front end is designed with an arc shape smaller than a semi-circle, creating a cylindrical pre-compression chamber. This curved geometry increases the compression ratio by improving the contact area and pressure distribution between the feed pusher and the waste material, while the self-contained design maintains structural simplicity.
