Sink Float Separation Tank

Description

In the quest for achieving top-notch recycling efficiency, the need for sophisticated separation technologies is paramount. At the forefront of this endeavor stands our Sink Float Separation Tank, a stellar performer in washing and segregating co-mingled plastic streams. Especially revered in PET bottle recycling plants, this machine excels in segregating PET plastic from polypropylene (PP) and polyethylene (PE) plastics, which constitute the bottle caps and labels.

Working Principle:

The cornerstone of our Sink Float Separation Tank is its ability to utilize water as the medium to differentiate between plastics based on their densities. Water, with a density of 1 g/cm³, acts as the reference point in this separation saga. As plastic pieces make their way into the tank, those with a density surpassing that of water sink, forming a heavy plastic stream at the tank’s bottom, which is then ushered out through a screw conveyor. Conversely, materials lighter than water float to the surface and make their exit at the top. The addition of certain additives can further refine the separation process, ensuring an immaculate segregation of materials.

Product Features:

• Dimension and Design: Our standard tanks, stretching 4-6 meters in length, come with ingeniously crafted rotating drums that propel the plastic pieces into the water. The extended design allows for ample separation and soaking time, culminating in a cleaner material stream.
• Durability: Fortified with high-grade 304 type stainless steel, the interior walls and rotating drums boast exceptional resistance to corrosion and oxidation (rust), underscoring our commitment to durability and long-term performance.
• Efficient Separation: Through the diligent use of water as a separation medium, our tank ensures a precise segregation of co-mingled plastics, facilitating a smoother recycling process.

Applications:

• PET Bottle Recycling: Granulating whole bottles often results in mixed streams of PET, PP, and PE plastics. Thanks to the Sink Float Separation Tank, PET plastic, with its density of 1.38 g/cm³, is efficiently segregated as it sinks to the bottom while PP and PE plastics float atop.
• Plastic Film Recycling: In scenarios involving plastic films, PP and PE films float, whereas contaminants like dirt, rocks, metals, and glass descend to the bottom, ready for collection and removal via a conveyor system.
• Rigid Plastic Recycling: The tank showcases its versatility in handling a variety of co-mingled rigid plastics, underlining its indispensable role in a comprehensive recycling setup.

In essence, our Sink Float Separation Tank stands as a linchpin in ensuring a meticulous separation of mixed plastic streams, thereby elevating the efficacy and output quality of recycling operations. By investing in this robust and reliable separation tank, recycling facilities are well-positioned to unlock a new level of operational excellence and resource recovery.
