Introducing the Stainless Steel Plate Frame Multi-layer Filter, a pinnacle of precision liquid filtration technology. With its exquisite mirror-polished exterior, this state-of-the-art machine employs advanced filter cloth or membrane filtration techniques. Enhanced with robust sealing strips and a stainless steel pump, it is expertly crafted for superior solid-liquid separation and liquid filtration. Ideal for a variety of industries, including laboratories, fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, food production, and cosmetics, this versatile filter promises unparalleled efficiency and reliability.
Working Principle
In operation, the suspension is expertly directed into each meticulously sealed filtration chamber of the apparatus. Utilizing pressure, the filtrate gracefully traverses the filtering layer and membrane, or other specialized filtering materials, emerging seamlessly through the outlet. Meanwhile, the residue is adeptly transformed into a filter cake within the plate frame, culminating in a precise and effective solid-liquid separation process.
Features
Crafted with premium stainless steel materials such as SUS304 or SUS316L, this machine epitomizes durability and corrosion resistance. The filter plates boast a sophisticated threaded design, facilitating effortless replacement of filtering materials tailored to the medium and production process—be it pre-filtration, semi-filtration, or fine filtration. Instantly achieve sterile filtration with micro-porous membranes. Users can seamlessly adjust layer counts to align with filtration volume demands, ensuring optimal production efficiency. The machine also excels at producing filter cloth leak-proof plate frame filters. Through pressurized sealing and filtering, it delivers unmatched liquid clarity without material wastage, and offers customizable multi-stage filtration devices to suit user specifications. The initial stage can incorporate coarser materials, while subsequent stages refine with finer materials, optimizing time and precision. Sealing components, crafted from silicone (fluorine rubber), offer superior heat resistance and non-toxic, leak-proof performance. An optional automatic return device can be included; by halting pump rotation and opening the return valve, sediment is automatically expelled, incorporating an air exhaust function, while enabling back-washing with pristine water through the return pipe for added convenience.
