Introducing the Stainless Steel Plate Frame Multi-layer Filter, a state-of-the-art precision liquid filtration machine that boasts an immaculate mirror-polished surface. This cutting-edge device utilizes premium filter cloth or membrane filtration, enhanced with superior sealing strips and a robust stainless steel pump. Perfectly designed for precise solid-liquid separation, it finds exceptional utility in diverse fields such as laboratories, fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, food processing, and cosmetics, delivering unmatched efficiency in liquid filtration.
Unveiling the Ingenious Working Principle
In this advanced system, the suspension is expertly pumped into each meticulously sealed filtration chamber. As pressure is applied, the innovative filtrate flows seamlessly through the filtering layer and filter membrane, or other sophisticated filtering materials, and is effortlessly discharged through the outlet. Meanwhile, the residue is artfully converted into a filter cake within the plate frame, achieving remarkable solid-liquid separation with absolute precision.
Impressive Features
Crafted with excellence, this machine is constructed using the highest-grade stainless steel, such as SUS304 or SUS316L, known for its exceptional corrosion resistance and durability. The filter plates are ingeniously designed with a threaded structure, providing the flexibility to replace filtering materials based on the filtering medium and production process, whether it be pre-filtration, semi-filtration, or fine filtration. Achieve sterile filtration with ease through direct use of micro-porous filter membranes. Users have the flexibility to adjust the number of layers to suit their specific filtration volume requirements, ensuring seamless production. The machine excels in producing leak-proof plate frame filters with filter cloth. Operating under pressure, it achieves impeccable sealing and filtration with zero liquid loss, superior liquid clarity, and the capability to customize multi-stage filtration devices tailored to user needs. The first filtration stage can employ coarser materials, while the second stage utilizes finer ones, optimizing time and enhancing filtration precision. All sealing components are crafted from silicone (fluorine rubber) rings, renowned for their heat resistance, non-toxicity, leak-proof nature, and exceptional sealing performance. For added convenience, the machine can be personalized with an automatic return device. When the pump ceases operation, simply open the return valve to automatically discharge all sediment with air exhaust functionality. Simultaneously, the machine can be effortlessly back-washed with clean water from the return pipe, offering unparalleled convenience.
