Long-Term Insulated Asphalt Storage Tank from Trusted China Suppliers and Factory for High-Temperature Storage
Main Functions
The large storage capacity meets the continuous production requirements, avoiding frequent feeding and melting, and ensuring the continuity of production.
The constant temperature and insulation maintain the asphalt at the flowing temperature (generally 130-180℃), preventing cooling and solidification.
The sedimentation and impurity removal: The asphalt remains in the tank for a long time, and mechanical impurities and coke powder naturally settle at the bottom of the tank.
The transfer and buffering: Connects the upstream melting equipment with the downstream production process, playing a role in regulating and stabilizing the supply.
Structural Characteristics
The tanks are mostly in vertical or horizontal cylindrical shapes made of steel, with volumes ranging from several tens to several thousand cubic meters.
The heating system is equipped with heat transfer oil coils / steam coils inside. Some small tanks use electric heating to ensure uniform overall temperature.
The outer wall of the insulation layer is wrapped with insulation materials such as rock wool and glass wool, and is covered with color steel or galvanized iron sheets to reduce heat loss.
Inlet port, outlet port, overflow port, bottom drainage port
Level gauge, thermometer, temperature measurement probe
Asphalt smoke exhaust port, manhole, maintenance port
Anti-static, lightning protection, safety guardrail, etc.
Working Method
The high-temperature liquid asphalt is sent into the tank by the asphalt melting device or the unloading device.
The coil pipe continuously heats up, keeping the asphalt in the tank at a constant temperature and in a flowable state.
During production, the asphalt is extracted from the bottom of the tank by the asphalt pump, passes through the filter and heater, and is sent to the process.
Impurities deposit at the bottom of the tank and are regularly cleaned through the sewage outlet.
Frequently Asked Questions
What is the typical storage temperature for asphalt in these tanks?
Asphalt is generally maintained at a constant flowing temperature between 130°C and 180°C to prevent cooling and solidification.
How does the tank handle impurities in the asphalt?
The asphalt remains in the tank for an extended period, allowing mechanical impurities and coke powder to naturally settle at the bottom, where they are regularly removed via a drainage port.
What heating methods are available for asphalt storage?
The tanks can be equipped with heat transfer oil coils, steam coils, or electric heating systems depending on the tank size and specific production requirements.
What materials are used for tank insulation?
The outer walls are typically wrapped with high-quality insulation materials like rock wool or glass wool, then protected by color steel or galvanized iron sheets.
What safety features are integrated into the storage tank?
Standard safety features include anti-static systems, lightning protection, safety guardrails, level gauges, and temperature measurement probes to ensure secure operation.
What are the common shapes and sizes of these tanks?
Tanks are usually vertical or horizontal cylindrical steel structures, with storage capacities ranging from a few dozen to several thousand cubic meters.
