Large Solid Asphalt Melting Tank Equipment - China Suppliers & Factory for Efficient Asphalt Heating Solutions
Product Description
For general melting volumes that are relatively large (2 - 15 t/h), a vertical coil structure is adopted; for smaller melting volumes (1 - 2 t/h), a horizontal tube bundle structure is used; for very small melting volumes (for testing purposes - 100 - 1000 kg/h), an electric heating structure is employed. While for block asphalt, an intermittent (discontinuous) tube bundle structure is generally used.
Main Structure
The main structure is engineered for efficiency and durability, consisting of the following key components:
Working Principle
Step 1: Melting & Initial Heating
The solid asphalt enters the melting zone through the feeding port. Under the action of high-temperature heat transfer oil in the coil pipes, the asphalt is heated, melted, and mixed by the agitator to ensure uniform heating. High-quality liquid asphalt is pressed into the secondary heating zone, while slag material enters the conical storage area.
Step 2: Secondary Heating & Purification
After melting, the asphalt enters the secondary heating zone from the bottom for further heating, dehydration, and sedimentation of impurities. Once the liquid level reaches the discharge port and the temperature meets requirements, qualified asphalt is stably discharged through a filter and transported to the storage tank.
Step 3: Cleaning & Maintenance
A discharge valve and manhole are located at the bottom. During cleaning, the liquid asphalt is pumped to a buffer tank, and the bottom slag mechanism discharges settled impurities. The manhole allows maintenance personnel access to the interior when needed.
Step 4: Temperature Regulation
A temperature measuring point at the outlet monitors the asphalt temperature. This controls the heat transfer oil inlet valve, adjusting the melting speed and preventing asphalt aging caused by overheating.
