    ​Detailed Description​

    ​Equipment Structure & Working Principle​

    1. ​Thermal Oil Heating System​

      • A thermal oil circulation pump (10m³/h flow rate) drives high-temperature thermal oil (180-240°C) through internal coils to evenly heat the asphalt in the tank.
      • Electric heating tubes (45kW, divided into three groups) support automatic start/stop and are interlocked with the thermal oil pump to prevent dry burning.
      • Dual temperature control: Bitumen temperature sensors (PV) and thermal oil controllers (SV) ensure safety, automatically cutting off heating during overtemperature.

    2. ​Mixing System​

      • A 7.5kW agitator motor (Rongcheng Hengli/Dandong Huanghai brands) paired with an XLD-6 reducer (35:1 speed ratio) ensures uniform mixing of high-viscosity asphalt.
      • Grease nipple-bearing design supports regular lubrication; 89mm-thick corrosion-resistant shaft withstands high temperatures.

    3. ​Safety & Automation​

      • DN50 safety valve (set pressure 0.35-0.4MPa) prevents overpressure; Schneider electrical components ensure electrical safety.
      • Three-way plug valve enables switching between unloading/pumping modes to avoid backflow; PLC interface simplifies operation.

    4. ​Energy-Saving Design​

      • Thermal oil expansion tank reserves 5mm liquid space to minimize overflow risks from thermal expansion.
      • 85% thermal efficiency reduces diesel consumption to 3-5kg per ton of asphalt (optional diesel burner).
