Introducing the Stainless Steel Plate Frame Multi-layer Filter, a state-of-the-art precision liquid filtration machine crafted for excellence. Its entire surface gleams with a mirror-polished finish, demonstrating not only its aesthetic appeal but its high-quality engineering. Utilizing advanced filter cloth or membrane technology, this machine is equipped with highly efficient sealing strips and a top-of-the-line stainless steel pump. It stands out as an indispensable tool for solid-liquid separation and liquid filtration across various industries including laboratories, fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, food, and cosmetics, offering unmatched versatility and reliability.
Working Principle
This innovative machine operates by channeling the suspension into each intricately sealed filtration chamber. Here, under carefully applied pressure, the filtrate gracefully traverses the filtering layer and its sophisticated membrane or alternate filtering materials, culminating in its elegant exit through the outlet. Simultaneously, the residue is meticulously transformed into a filter cake within the plate frame, perfectly executing the essential process of solid-liquid separation with remarkable efficiency.
Features
Crafted with precision, this machine boasts the use of superior stainless steel materials, such as SUS304 or SUS316L, ensuring exceptional corrosion resistance and longevity. The filter plates are ingeniously designed with a threaded structure, allowing for seamless replacement of filtering materials tailored to the specific filtering medium and production process, whether it be pre-filtration, semi-filtration, or fine filtration. By employing micro-porous filter membranes, it can achieve the pinnacle of sterile filtration. The machine's adaptability extends to varying filtration volumes, enabling users to adjust the number of layers to suit production demands. Its capacity to produce leak-proof plate frame filters using filter cloth enhances its prowess. Operating at optimal pressure, the machine ensures zero liquid material loss, outstanding liquid clarity, and is equipped for multi-stage filtration customization to meet diverse user needs. The first stage may utilize coarser filtering materials, transitioning to finer ones in subsequent stages, optimizing time and elevating filtration precision. Every sealing component is impeccably designed with silicone (fluorine rubber) sealing rings, known for their heat resistance, non-toxicity, leak-proof design, and exceptional sealing capabilities. For added convenience, the machine can be customized with an automatic return device. When the pump ceases operation, the return valve can be opened to automatically discharge all sediment (aided by an air exhaust function), while the return pipe facilitates back-washing with clean water, offering unparalleled convenience.
