Introducing the Stainless Steel Plate Frame Multi-layer Filter, a cutting-edge precision liquid filtration machine designed to exceed your expectations. Boasting an exquisite mirror-polished surface, this device employs advanced filter cloth or membrane filtration techniques. Equipped with robust sealing strips and a high-grade stainless steel pump, it is the epitome of reliability and efficiency. Ideal for solid-liquid separation and liquid filtration across a diverse range of industries, this versatile machine excels in laboratories, fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, as well as food and cosmetics sectors.
Working Principle
Immerse yourself in the sophisticated workings of this filtration marvel. The process begins as the suspension is seamlessly pumped into the meticulously sealed filtration chambers. Under precise pressure, the filtrate gracefully traverses through the filtering layer, utilizing a filter membrane or other advanced filtering materials. Finally, it is elegantly discharged through the outlet while the residue forms a compact filter cake within the plate frame, thus achieving impeccable solid-liquid separation.
Features
Crafted from superior stainless steel materials such as SUS304 or SUS316L, this machine promises unmatched corrosion resistance and longevity. The innovative threaded structure of the filter plates permits the effortless replacement of filtering materials tailored to your specific medium and production process, whether it be pre-filtration, semi-filtration, or fine filtration. Direct application of micro-porous filter membranes guarantees sterile filtration. Flexibility is key, as users can adjust the number of layers to match their filtration volume requirements. This machine is engineered to produce filter cloth leak-proof plate frame filters, ensuring seamless operation. With pressure-sealed filtering, there is zero liquid material loss, crystal-clear liquid output, and the option to customize multi-stage filtration devices to suit your needs. Initiate with a coarse first stage and follow with a refined second stage to optimize time and enhance filtration accuracy. Featuring top-tier silicone (fluorine rubber) sealing rings, all components boast heat resistance, non-toxicity, leak-proof assurance, and superior sealing performance. User convenience is paramount, with the option to customize an automatic return device. Upon pump cessation, the return valve can be opened to automatically discharge all sediment while seamlessly allowing for back-washing with clean water via the return pipe-ensuring unrivaled convenience and efficiency.
