Introducing the Stainless Steel Plate Frame Multi-layer Filter - an epitome of precision liquid filtration technology! Sporting an exquisite mirror-polished surface, this advanced machine employs either filter cloth or membrane filtration to cater to your diverse needs. With its dependable sealing strips and robust stainless steel pump, it is your go-to solution for seamless solid-liquid separation and liquid filtration. Ideal for a multitude of industries including laboratories, fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, food, and cosmetics, it promises unparalleled efficiency and reliability in every application.
Working Principle
The ingenious working mechanism of this machine begins with the suspension being expertly pumped into each meticulously sealed filtration chamber. As pressure builds, the filtrate smoothly traverses through the filtering layer, filter membrane, or other filtering materials, making its way through the outlet. Meanwhile, the residue is skillfully transformed into filter cake within the plate frame, flawlessly executing the vital task of solid-liquid separation.
Features
Crafted with premium stainless steel materials such as SUS304 or SUS316L, this machine boasts remarkable corrosion resistance and exceptional durability. Its filter plates are ingeniously designed with a threaded structure, allowing effortless replacement of filtering materials to suit varying mediums and production processes, be it pre-filtration, semi-filtration, or fine filtration. For sterile filtration, micro-porous filter membranes can be directly employed. Tailor the number of layers based on filtration volume to precisely meet production demands. The innovative design ensures zero liquid material loss, delivering crystal-clear liquids. Customizable multi-stage filtration devices can be engineered to elevate efficiency; initiate with coarser materials and conclude with finer ones, optimizing time and accuracy. The machine employs silicone (fluorine rubber) sealing rings, lauded for their heat resistance, non-toxicity, leak-proof nature, and superior sealing capabilities. Additionally, an automatic return device can be configured as per user requirements. When the pump ceases operation, simply open the return valve to automatically expel all sediment, combined with an air exhaust function, and enjoy the convenience of back-washing the machine with pristine water from the return pipe. Experience unmatched ease and efficiency today!
