Ceramic friction ring

Main functions
As the rotating sealing and friction contact interface between the filter plate and the transmission/distribution mechanism, it maintains the system vacuum level and reduces medium leakage, ensuring continuous and stable solid-liquid separation.
As the bearing and sealing component of the distribution head, it cooperates to achieve the channel switching for suction/counterflow conditions, ensuring that the filtrate is discharged along the set path and the filter plate is backwashed.
In some models, it also performs the function of filtrate diversion, allowing the filtrate to smoothly enter the vacuum tank through the friction ring (friction disc) and be discharged, thereby improving the efficiency of liquid discharge and backwashing.
Cooperation with related components
With ceramic filter plates: The filter plate is the core filtering medium of the equipment (porous ceramic, with pores ranging from 0.1 to 10 μm), while the friction disc does not directly perform filtration but provides stable sealing and channel conditions.
With distribution heads/distributors: The friction disc (friction disc) and the distribution head work together to complete the cycle switching of vacuum suction and counterflow, which is a key link in maintaining the filtration-cleaning cycle.
With scrapers: The discharge area is scraped off by the scraper, and the friction disc ensures that the sealing and channel conditions during the scraping and backwashing stages are not affected, reducing secondary entrainment and leakage.
With agitators: The agitator prevents the slurry from settling, while the friction disc maintains the sealing and channel stability during the drum rotation, jointly ensuring continuous operation.
