Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional small-sized testing device is used, then the device structure is simplified and manufacturing cost is reduced, but the device cannot provide enough function zones to perform washing and drying processes multiple times
Solution Approach 1:
The testing device is divided into distinct functional zones: a filtering zone for initial filtration, a washing zone for multiple washing operations, and a drying zone for drying processes. Each zone is equipped with independent control systems and can operate sequentially or independently, allowing multiple cycles of washing and drying to be performed without requiring a completely new device configuration.
2Reliability
If a conventional testing device with all industrial components is used, then the testing can be performed, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The invention extracts only the essential functional components needed for testing from the complete industrial rotary pressure filter system. Instead of including all industrial components such as the full driving system and auxiliary equipment, the testing device incorporates only the filtering frame, pressure control system, washing system, and drying system necessary for material characteristic testing, thereby simplifying the overall structure while maintaining testing reliability.
3Reliability
If a conventional testing device is used, then testing can be conducted, but the testing procedure becomes complex and cost increases
Solution Approach 1:
The control systems for filtering, washing, and drying operations are merged into a single integrated control unit that can manage all testing procedures through unified operation. The device allows operators to execute multiple washing and drying cycles through a standardized control interface, simplifying the testing procedure while maintaining the capability to perform comprehensive material characterization tests.

AI summary
The present invention relates to a rotary pressure filter testing apparatus, a testing method and a design method thereof. The apparatus comprises a stabilizer tank; a buffer tank connected to the stabilizer tank; a filter frame disposed beneath the buffer tank, and connected to the buffer tank; a liquid receiving tank disposed beneath the filter frame; an electronic balance disposed at bottom of the liquid receiving tank; and a seconds counter. The testing method is to add a certain amount of calculated testing tank into the filter frame, then introduce a gas with a certain pressure into the stabilizer tank, fill the filter frame through the buffer tank, then open a valve at bottom of the filter frame, measure a mass of discharged mother liquid in the filter frame, measure time of the filtering process, and sample and analyze the filtered filter cake and the mother liquid according to actual needs; subsequently, perform cleaning and drying processes sequentially according to such method. The present invention largely reduces the testing costs, and meanwhile, actual working conditions can be simulated more accurately, thereby obtaining accurate and reliable design data.
