AI Technical Summary
Existing waste asphalt mixture separation devices suffer from problems such as poor separation effect, high energy consumption, serious pollution, complex equipment and high safety risks. Traditional methods such as extraction separation and combustion methods have drawbacks such as the mixing of fine mineral powder into the asphalt solution, high energy consumption, high requirements for high temperature and corrosion resistance of equipment, and easy clogging of physical separation devices.
The system employs a low-temperature control component to maintain the separation chamber at a low temperature of -10℃ to -20℃. Combined with a vibration crushing component and a screening component, it utilizes density differences to separate asphalt from aggregates. The separation of asphalt and aggregates is achieved through a separation solvent provided by a solvent storage component. An integrated control platform monitors and regulates the operation of each component in real time.
It achieves efficient, precise, and stable separation of asphalt and aggregates, reduces energy consumption and pollution, improves separation efficiency and material integrity, ensures equipment safety, and supports the recycling of solvents.
