Dongguan Xinbao Machinery Co., Ltd., a trusted supplier to global markets including North America, South America, Europe, Asia, Africa, and Oceania, presents its advanced Industrial Plastic Sink Float Tank. Engineered for efficiency in mixed material cleaning and separation, this robust system tackles the critical challenge of purifying recycled plastics or other materials with varying densities. Offering both Single Screw and Double Screw configurations, it provides adaptable solutions for diverse throughput and contamination levels, ensuring optimal resource recovery and waste reduction for your operation.
Core Technology & Operation:
- Sink-Float Separation: Utilizes the fundamental principle of density differences. Materials are immersed in a controlled water medium; heavier contaminants sink, while target materials (like specific plastics) float, enabling effective separation.
- Agitation Mechanism: Features powerful screw agitators (Single or Double) that vigorously stir the water-material mixture. This action:
- Breaks apart clumped materials.
- Dislodges stubborn dirt, labels, adhesives, and organic residues.
- Ensures thorough washing of all particle surfaces.
- Facilitates the separation process by keeping materials in suspension.
- Continuous Flow Design: Materials are fed in continuously, washed and separated, then discharged (floats via overflow weir, sinks via bottom screw/conveyor), maximizing processing efficiency.
Configuration Options & Advantages:
-
Single Screw Tank:
- Ideal for standard cleaning and separation tasks with moderate contamination levels.
- Offers a cost-effective solution with reliable performance.
- Simpler design for easier maintenance.
-
Double Screw Tank:
- Provides significantly higher agitation intensity and cleaning power.
- Superior for heavily contaminated materials, sticky residues, or demanding separation requirements.
- Enhanced material turnover for more consistent results.
Robust Construction & Key Features:
- Durable Industrial Plastic: Constructed from high-quality, wear-resistant, corrosion-proof plastic (e.g., HDPE, PP), ensuring longevity even in harsh, wet, and chemically demanding environments. Resists rust and degradation.
- Heavy-Duty Screw Agitators: Screws are built with robust materials and designs for sustained heavy-duty operation, minimizing wear and downtime.
- Efficient Discharge Systems: Separate, optimized outlets for floating materials (overflow weir/skimming) and settled contaminants/sinks (auger or screw conveyor at the bottom) ensure clean separation and efficient removal.
- Water Management: Designed for integration with water circulation and filtration systems to optimize water usage.
- Customizable Design: Sizes, specific dimensions, and certain features can often be tailored to fit specific plant layouts and processing requirements.
Typical Technical Specifications (Examples - Customizable):
| Parameter | Single Screw Option | Double Screw Option |
|---|---|---|
| Tank Capacity (Example) | 1,000 - 5,000 Liters | 2,000 - 10,000 Liters |
| Length (Example) | 3m - 6m | 4m - 8m |
| Width (Example) | 1.2m - 1.8m | 1.5m - 2.2m |
| Agitation Power (Example) | 5.5kW - 15kW | 11kW - 22kW (per screw) |
| Throughput Capacity* | 500 - 1,500 kg/h | 1,000 - 3,000 kg/h |
*Highly dependent on material type, contamination level, and desired cleanliness.
Benefits for Your Business:
- Enhanced Material Purity: Achieve superior separation of target materials (e.g., specific plastic types) from contaminants, dirt, metals, and other polymers, significantly increasing the value of your recycled output.
- Effective Contaminant Removal: Thoroughly cleans materials, removing labels, adhesives, food residue, sand, and other impurities that degrade quality.
- Increased Process Efficiency: Continuous operation allows for high-volume processing, streamlining your recycling or waste handling line.
- Reduced Operating Costs: Durable plastic construction minimizes maintenance needs and replacement costs. Efficient design can contribute to lower water and energy consumption per ton processed.
- Flexibility: Choosing between Single or Double Screw configurations allows you to match the machine's power and cost precisely to your specific material challenges and budget.
- Reliability: Robust design ensures consistent performance and uptime in demanding industrial environments.
Applications:
- Plastic Recycling Facilities (PET, HDPE, PP, LDPE flake cleaning)
- Separation of different plastic types based on density
- Removal of dirt, sand, organics, and labels from plastic flakes or regrind
- Washing and cleaning of post-consumer or post-industrial plastic waste
- Cleaning and separation in other material recovery processes (e.g., certain metals, minerals)

Frequently Asked Questions (FAQ):
Q1: How effective is this sink float tank at removing sticky labels and adhesives from plastics?
A1: The combination of vigorous screw agitation and the friction between materials in the water bath is highly effective at dislodging and removing most labels, films, and adhesive residues. The Double Screw option provides even more intense cleaning action for stubborn adhesives.
Q2: Should I choose the Single Screw or Double Screw configuration?
A2: The choice depends on your material contamination level and desired throughput. Single Screw is suitable for standard cleaning. Double Screw offers significantly higher agitation power, making it ideal for heavily contaminated materials, sticky residues, or when higher throughput capacity with thorough cleaning is needed.
Q3: What materials is the tank itself made from, and why is plastic used?
A3: The tank is constructed from industrial-grade plastics like HDPE or PP. This offers superior corrosion resistance against water and chemicals, eliminates rust issues common with steel, provides good wear resistance, and ensures a long operational lifespan in wet industrial environments.
Q4: Can this tank handle materials other than plastics?
A4: Yes, while primarily designed for plastics, the sink-float principle can be applied to separate other materials based on density differences, provided they are compatible with water washing. Consult with us about your specific material mix.
Q5: How is water usage managed with this equipment?
A5: The tank is designed to integrate with water circulation systems. Process water can be filtered (e.g., using sedimentation tanks, hydrocyclones, or filters) and reused, significantly reducing fresh water consumption. Specific water management setups depend on the plant.
Q6: What maintenance does the sink float tank require?
A6: Maintenance primarily involves periodic inspection of the screw agitators and bearings for wear, checking drive components (gearbox, motor), and ensuring discharge mechanisms are clear. The plastic construction minimizes corrosion-related maintenance.
Q7: Can the tank be customized for my factory space or specific needs?
A7: Yes, Dongguan Xinbao Machinery often offers customization options. Tank dimensions (length, width, depth), discharge mechanisms, and certain features can potentially be adapted to fit your layout and processing requirements. Discuss your needs with us.
Q8: What kind of power supply is required?
A8: The required power depends on the size and configuration (Single or Double Screw) of the tank. Motors typically range from 5.5kW up to 22kW or more for larger Double Screw units. Specific voltage and phase requirements (e.g., 380V 3-phase) will be confirmed based on the model.
