Air-Cooled Water-Cooled Drum Cooler Machine

This machine is a cooling equipment for sand treatment, which cools the hot recycled sand to a certain temperature, and automatically regulates the sand temperature through PLC. The horizontal cooling machine is a cooling equipment for sand treatment, which cools the hot recycled sand to a certain temperature. The equipment adopts a combination of water cooling and air cooling, and the sand flow rate is automatically controlled by PLC to quickly cool the sand temperature.

There is circulating water between the outer wall of the drum and the outer cover, which carries most of the heat. The axial flow fan blows through the sand raised by the drum and takes away the hot air through the dust removal port, ensuring the cooling temperature and dust removal effect of the molding sand.

Working Principle

Hot recycled sand enters the drum from the feeding hopper. As the drum rotates, the spiral lines lift and transport the sand, allowing air and water to efficiently absorb heat. An axial flow fan directs airflow from the sand outlet into the drum, guiding heat and dust toward the exhaust. The hot air passes through a cyclone dust collector, which removes dust before clean air is discharged. Water pipes spray both the inside and outside of the drum, providing rapid cooling and ensuring sand reaches the desired temperature efficiently. A blocking wheel system prevents excessive axial force, ensuring safe and stable operation.

Structure and Components

Horizontal Cooling Outer Box: Robust frame housing the drum and cooling systems.
Horizontal Cooling Inner Drum: Cylindrical drum with δ9 spiral steel pipes and internal spiral lines for lifting and transporting sand.
Gear Drive & Drive Device: Ensures smooth drum rotation and uniform sand movement.
Water-Cooling System: Sprays water on the drum exterior to accelerate heat transfer.
Dust Removal Assembly: Dust collection port with axial flow fan and cyclone dust collector ensures safe and clean operation.

Performance Advantages

Rapid and Uniform Cooling: Optimized design reduces cooling time without compromising sand quality.
Consistent Sand Quality: Precise temperature control prevents thermal damage to sand grains.
Energy Efficiency: Smart use of water and air reduces operational costs.
Durable Construction: Heavy-duty drum and drive system ensure long-term reliability.
