Introducing the Stainless Steel Plate Frame Multi-layer Filter, a precision liquid filtration marvel! This machine boasts a sleek, mirror-polished surface, utilizing advanced filter cloth or membrane filtration technology. Enhanced with sealing strips and a robust stainless steel pump, it is the epitome of efficiency for solid-liquid separation and liquid filtration. Perfectly suited for industries ranging from laboratories to fine chemicals, pharmaceuticals, traditional Chinese medicine extraction, food, and cosmetics, this filter is a testament to innovation and craftsmanship.
Working Principle
The ingenious operation of this machine begins with the suspension being pumped into each meticulously sealed filtration chamber. Under pressure, the filtrate elegantly traverses through the filtering layer and membrane, or other chosen filtering materials, to be seamlessly discharged via the outlet. Meanwhile, the residue forms a compact filter cake within the plate frame, effectively achieving the goal of solid-liquid separation with utmost precision.
Features
Crafted from premium stainless steel materials such as SUS304 or SUS316L, this filter machine stands out for its exceptional corrosion resistance and durability. The innovative threaded structure of the filter plates allows for easy replacement of filtering materials, accommodating various filtering media and production processes from pre-filtration to fine filtration. Achieve sterile filtration effortlessly with micro-porous filter membranes. Adapt the number of layers to align with production requirements, resulting in a bespoke solution for any operation. The machine excels in leak-proof performance, thanks to its impeccable filter cloth plate frame design. Operating under pressure ensures zero liquid loss, crystal-clear filtrates, and the flexibility to customize multi-stage filtration devices per specific user needs. Start with coarser materials in the initial stage and transition to finer materials in subsequent stages to enhance efficiency and precision. All sealing components incorporate silicone (fluorine rubber) sealing rings that are heat-resistant, non-toxic, and provide unparalleled leak-proof performance. Additionally, the machine can be tailored with an automatic return feature, allowing for seamless sediment discharge and convenient back-washing with clean water, thanks to the return pipe. Experience unmatched operational convenience and efficiency tailored to your needs.
