Asphalt Emulsification Equipment Operation Procedures

I. Equipment Preparation

1. Daily Inspection: Before starting the equipment each day, inspect all components and accessories to ensure they are intact, free from damage, loose parts, or abnormal wear.
2. Power Supply Check: Ensure the power supply lines are in good condition, with no exposure or aging. Verify that all electrical connections are secure and properly grounded.
3. Heating System: Inspect the boiler, burner, and fuel supply system to ensure they can start normally and reach the preset temperature. Preheat the boiler to the appropriate operating temperature.
4. Raw Material Preparation: Confirm sufficient storage of asphalt, emulsifier, and other necessary raw materials. Ensure that transfer pipelines are unobstructed, and valves are in the correct positions.
5. Safety Devices: Check the functionality of emergency stop buttons, temperature and pressure alarm systems, and other safety features.

II. Operation Procedure

1. Startup and Preheating: First, activate the heating system and preheat the equipment for typically 30 minutes to 1 hour, ensuring all sections reach the required operating temperatures.
2. Parameter Setting: Adjust the parameters of feed pumps, mixers, heaters, etc., based on the production formula, ensuring precise ratios, temperatures, and flow rates for asphalt and emulsifier.
3. Mixer and Heater Activation: Start the mixer, adjusting to the appropriate speed, and activate the heaters to allow asphalt and emulsifier to mix thoroughly at the set temperature.
4. Emulsification Reaction: Monitor pressure and temperature within the equipment, making adjustments as needed to ensure the emulsification reaction proceeds smoothly. Conduct multiple samples during the process for quality assurance.
5. Product Discharge: Once the emulsified asphalt meets quality standards, open the discharge valve to transfer the product into storage tanks or transportation equipment as planned.
6. Shutdown and Cleaning: After production, shut down all equipment. Once temperatures drop to a safe range, thoroughly clean the equipment to remove residues and maintain cleanliness.

III. Safety Measures

1. Personal Protective Equipment (PPE): Operators must wear complete PPE, including protective clothing, safety helmets, goggles, gloves, and respirators as necessary.
2. Operational Compliance: Strictly follow operation procedures, avoiding unauthorized adjustments to equipment parameters or opening hazardous area guards.
3. Area Restriction: Non-operators are prohibited from entering the operation area to ensure safety and order.
4. Ventilation: Maintain adequate ventilation in the equipment area to prevent the accumulation of toxic or harmful gases. Activate ventilation systems as necessary.
5. Emergency Preparedness: Develop emergency response plans, outlining actions and evacuation routes in case of emergencies. Conduct regular drills for preparedness.

IV. Equipment Maintenance

1. Scheduled Maintenance: Based on the equipment maintenance manual, establish and execute a regular maintenance schedule, covering inspections, cleaning, lubrication, and adjustments.
2. Professional Repairs: For complex faults or specialized maintenance tasks, contact professional service personnel for handling.
3. Record Keeping: Maintain comprehensive records of equipment operation and maintenance, detailing equipment status, maintenance activities, and repair history for tracking, analysis, and continuous improvement.
4. Training and Education: Regularly provide safety education and equipment operation training to operators, enhancing their skills and safety awareness.

By strictly adhering to these procedures, the asphalt emulsification equipment can operate safely, efficiently, and reliably, enhancing production efficiency and product quality.
