Washing device and extraction system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing devices for extraction device filters are large and complex, making installation and use difficult, and require a configuration that moves along the filter, leading to uneven washing.
Innovation Solution
A washing device with a fixed tube body and nozzles that inject fluid towards the filter while the lid body revolves, allowing for reliable and uniform washing without moving the tube body, reducing device size and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the washing device uses a tube body that moves along the filter, then it can wash the filter surface, but the device becomes large and complex
Solution Approach 1:
Instead of moving the tube body along the filter as in conventional devices, this invention inverts the approach by keeping the tube body fixed and moving the lid body (carrying the filter) relative to the tube body. This inversion eliminates the need for complex moving tube mechanisms while achieving complete filter surface coverage through the revolving lid body.
2Reliability
If the tube body moves along the filter, then washing can be performed, but the device size increases
Solution Approach 1:
The invention swaps the moving and fixed components: the tube body is fixed in position while the lid body revolves around the extraction tank. This eliminates the need for a large moving tube assembly, significantly reducing device size while maintaining complete washing coverage through the revolving motion.
3Reliability
If the tube body moves along the filter, then washing can be performed, but uneven washing occurs
Solution Approach 1:
By fixing the tube body and revolving the lid body with the filter, the invention ensures that the fluid ejection ports maintain a constant distance and fixed angle relative to the filter surface throughout the revolution. This eliminates positioning errors and speed variations associated with moving tubes, achieving uniform washing across the entire filter surface.
4Device complexity
If the washing device has a simple fixed configuration, then device size is reduced, but washing reliability may be compromised
Solution Approach 1:
While the tube body is fixed, the lid body is designed to revolve around the extraction tank, introducing dynamic motion to the filter position. This dynamic revolution ensures complete coverage of the filter surface by the fixed fluid ejection ports, maintaining washing reliability without requiring a complex moving tube structure.
