Experience the pinnacle of precision with our Stainless Steel Plate Frame Multi-layer Filter, a marvel of liquid filtration engineering. Boasting a stunning mirror-polished finish, this sophisticated machine employs advanced filter cloth or membrane filtration techniques. It comes complete with sealing strips and a robust stainless steel pump, making it an ideal choice for those demanding effective solid-liquid separation and superior liquid filtration. This versatile apparatus is perfect for usage across a spectrum of industries including laboratories, fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, the food sector, and cosmetics, ensuring purity and precision in every drop.
Working Principle
Witness the science of filtration in action! As the suspension is adeptly channeled into each meticulously sealed filtration chamber, pressure drives the filtrate seamlessly through the filtering layer, membrane, or other specialized materials. The purified liquid is elegantly discharged through the outlet, while the remaining residue forms a meticulously compacted filter cake within the plate frame. This ingenious process culminates in achieving flawless solid-liquid separation, delivering unparalleled filtration results.
Features
Crafted from premium stainless steel materials, such as SUS304 or SUS316L, this machine is the epitome of durability and corrosion resistance. The ingeniously designed filter plates come with a threaded structure, offering the flexibility to swap various filtering materials tailored to the filtering medium and production process requirements, whether it be pre-filtration, semi-filtration, or fine filtration. For those seeking sterile conditions, micro-porous filter membranes deliver outstanding results. The user-friendly design allows for easy adjustment of the filter layers based on volume demands, accommodating diverse production needs. Our innovative machine also features filter cloth leak-proof plate frame filters. Pressurized sealing and filtration ensure no liquid loss, offering crystal-clear clarity and the capability to customize multi-stage filtration devices tailored to user specifications. Employing coarse filtering materials in the initial stage, followed by finer selections in subsequent stages, optimizes time efficiency and enhances filtration precision. All sealing elements are crafted from high-grade silicone (fluorine rubber), known for its heat resistance, non-toxicity, and impeccable sealing performance. For added convenience, the machine can be outfitted with an automatic return device, effortlessly discharging sediment and facilitating back-washing with clean water, all at the flick of a valve, ensuring unprecedented ease of operation and maintenance.
