Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If filter plates are separated in batches to improve production efficiency, then the separation time is reduced, but adhesive filter cakes with microparticles cannot automatically fall off requiring manual removal
Solution Approach 1:
The patent applies a shaking device with an oscillating mechanism that generates mechanical vibration to detach adhesive filter cakes from filter plates. The shaking rod, driven by a motor through a transmission mechanism, oscillates to create sufficient force to break the adhesion between filter cakes and filter plates, enabling automatic removal without manual intervention while maintaining batch separation efficiency
Solution Approach 2:
The patent replaces manual mechanical removal with an automated shaking mechanism. The motor-driven oscillating system substitutes human labor, automatically performing the removal function through controlled mechanical vibration and motion, thereby improving ease of operation while maintaining high productivity
2Object-generated harmful factors
If manual removal of filter cakes is conducted, then adhesive filter cakes can be removed, but labor intensity increases and filter cloth may be damaged
Solution Approach 1:
The shaking device generates controlled mechanical vibration that selectively detaches filter cakes from filter plates without applying excessive force to the filter cloth. The oscillating motion creates sufficient shear force to break adhesion while the brief duration and controlled amplitude protect the filter cloth from damage, maintaining reliability
Solution Approach 2:
The shaking device enables the filter press system to perform its own filter cake removal function automatically. The system self-services by using the shaking mechanism to detach and remove filter cakes without external manual intervention, reducing labor intensity while protecting filter cloth integrity through controlled automated action
3Extent of automation
If cleaning mechanisms are added to automatically clean filter clothes, then manual removal is eliminated, but device complexity and energy consumption increase
Solution Approach 1:
The shaking device is integrated with the existing filter press structure, merging the cleaning function into the plate separation process. The shaking rod is positioned to work on multiple filter plates simultaneously during the batch separation operation, combining separation and cleaning functions into a single integrated mechanism, thereby reducing overall device complexity
Solution Approach 2:
The shaking mechanism serves multiple functions: it aids in the batch separation of filter plates and simultaneously cleans adhesive filter cakes from the filter cloth surfaces. This multi-functional design eliminates the need for separate dedicated cleaning mechanisms, reducing device complexity while achieving high automation

AI summary
A grouping vibration device for filter plates (4) of a press filter used for pulling the filter plates (4) of the press filter in groups to discharge the filter cake, which vibrates a vibration rod (11) by the use of a cylinder assembly (6) to vibrate the filter cloth bracket rod (27), thereby discharging the filter cake. After the first group of filter plates (4) is pulled, a movable frame is transmitted by a driven gear (8) of a retarding braking motor (9) to the vibrating location. Then a gas source bypass valve (19) is opened to make the cylinder to hammer the vibration rod (11) by a gas source three-joint workpiece (13). The vibration times of the cylinder are controlled. After the vibration, the vibration rod (11) is automatically retracted by a sleeve spring device (5) and the filter cloth bracket rod (27) is vibrated by the vibration rod (11) to discharge the filter cake automatically. After the vibration of the first group, the second group of filter plates (4) begins to be pulled. After the grouping vibration of the filter plates (4) is completed successively, a position limiter disposed at the ultimate end makes the movable frame back to the original position. The course of the vibration procedure is controlled by a PLC program. The programmable control of the vibration times, travel distance, etc. is achieved.
