    Description

    Core Technologies

    1. District Heating Technology

      • Zoned Heating Density: Higher heater density near the asphalt outlet ensures rapid heating and temperature stability, minimizing energy waste.
      • Independent Control: Multiple electric heater groups can be activated or deactivated dynamically based on production needs.
    2. Dual Heating Modes

      • Direct Heating: Electric heaters transfer heat to asphalt via isolation sleeves, preventing direct contact and surface coking.
      • Indirect Heating (Optional): Electric thermal oil furnace heats oil, which circulates through internal coils to warm asphalt without aging.
    3. Smart Temperature Control

      • Dual-Sensor System:
        • Asphalt Temperature Sensor: Automatically starts/stops heaters within preset temperature limits.
        • Heater Sleeve Sensor: Monitors isolation sleeve temperature to prevent overheating and carbonization.
      • Automation: Centralized control cabinet with overload protection, emergency stop, and remote monitoring (optional).

    Structural Design

    • Tank Construction:
      • Horizontal Cylindrical/Square Tanks: DZL-10 to DZL-35 (cylindrical), DZL-45 (square: 11m×2.2m×2.32m), optimized for container shipping.
      • Insulation: 10cm rock wool (sides and bottom) + 5cm rock wool (top), wrapped in 0.5mm corrugated steel or 2mm flat panels.
    • Heater System:
      • Isolation Sleeves: Boiler-grade seamless steel tubes (GB/T3087) enclose heaters for easy maintenance.
      • Scalable Power: 5KW per heater group (e.g., DZL-45: 20 groups, ≤100KW total).

    Key Components

    • Bitumen Pump System: 80×2-46 screw pump (24m³/h flow rate) with pneumatic three-way valve for efficient discharge.
    • Thermal Oil Furnace (Optional): 21.5KW electric heater with precision temperature control for pumps and pipelines.
    • Monitoring Instruments: Floating ball level gauge, digital thermometer, and pressure sensors for real-time status tracking.

    Durability & Safety

    • Anti-Corrosion Treatment: Anti-rust coating on internal/external surfaces; X-ray weld inspection for critical joints.
    • Safety Features: Non-slip platforms, explosion-proof control cabinet (Exd II BT4 standard, optional), and guardrails.
