Introducing our Stainless Steel Plate Frame Multi-layer Filter, a pinnacle of precision in liquid filtration technology. This exceptional machine boasts an impeccably mirror-polished surface, employing filter cloth or membrane filtration to perfection. It is ingeniously designed with sealing strips and a robust stainless steel pump, making it the ideal solution for solid-liquid separation and liquid filtration across a wide array of industries. Whether in advanced laboratories, fine chemical processing, pharmaceutical manufacturing, traditional Chinese medicine extraction, food production, or cosmetic innovation, this machine delivers superior performance and reliability.
Working Principle
The ingenious operation of this machine begins as the suspension is meticulously pumped into the sealed filtration chambers. Utilizing pressure as its driving force, the filtrate gracefully traverses through the filtering layer and filter membrane, or other chosen filtering materials, effortlessly exiting through the outlet. Meanwhile, the residue elegantly forms a filter cake within the plate frame, masterfully accomplishing the desired solid-liquid separation with efficiency and precision.
Features
Crafted with the highest standards, this machine utilizes premium stainless steel materials, including SUS304 or SUS316L, ensuring remarkable corrosion resistance and durability. The filter plates are innovatively designed with a threaded structure, allowing seamless replacement of filtering materials to suit varying medium and production processes, be it pre-filtration, semi-filtration, or fine filtration. For ultimate purity, micro-porous filter membranes can be employed for sterile filtration. The machine's versatility is further enhanced by the ability to adjust the number of layers to accommodate varying filtration volumes, precisely tailored to production needs. Additionally, it excels in producing leak-proof plate frame filters, sealing and filtering under pressure to prevent any liquid loss, guaranteeing clarity and precision. Users can personalize multi-stage filtration setups to meet specific requirements, with options for coarser initial stage filtering and finer secondary stage filtration, optimizing time and accuracy. All sealing components, crafted from silicone (fluorine rubber) sealing rings, are heat-resistant, non-toxic, and expertly designed to prevent leaks and ensure perfect sealing. For added convenience, an automatic return device can be customized, facilitating the effortless discharge of sediment and enabling back-washing with clean water through the return pipe, proving exceptionally user-friendly and efficient.
