Core Technologies
-
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.
-
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.
-
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).
- Dual-Sensor System:
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.
