Product Description
Introducing the pinnacle of sand cooling technology: the Rapid Cooling Sand Cooler Multi-Cooler with Customization Options Available. This cutting-edge machine specializes in the cooling of reclaimed green sand, ensuring a seamless and uniform blend of temperature, humidity, and composition. Designed with a compact and sturdy structure, it guarantees stable operation, minimal energy consumption, and exceptional cooling efficiency. At its core is a high-pressure fan that propels the old sand into a boiling state, optimizing the cooling process to perfection. The innovative adjustable unloading door precisely controls the material flow, further enhancing the cooling efficiency. With an automated system encompassing temperature and humidification regulation, alongside a comprehensive blower, induced fan, and water system, this machine constitutes the ultimate old sand cooling unit.
Versatility is key with the Rapid Cooling Sand Cooler, which can be installed to discharge materials in two configurations: straight line or vertical. When placing your order, you can choose from left or right unloading directions, ensuring seamless integration into your existing workflow.
In the demanding environment of a foundry workshop, the cooling uniformity and efficiency of high-temperature wet sand (80-150ºC, 3-8% moisture) are pivotal in enhancing the reuse rate of molding sand and the quality of castings. The double-disc stirring cooler emerges as a beacon of efficiency, offering a customizable, energy-saving solution for old sand cooling. Utilizing the principles of boiling heat exchange and multi-parameter precise control, this equipment redefines energy efficiency standards. This article delves into how this revolutionary machine transforms the sand processing landscape through advanced thermodynamics, process adaptability, intelligent control systems, and applicability across multiple industries.
1. Technical principle and core component design
The Rapid Cooling Sand Cooler achieves remarkable technological advancements with two groundbreaking technologies: fluidized cooling and dynamic homogenization, tailored to the physical properties of old sand particles (0.15-1.2mm):
Boiling state heat exchange system:
Revolutionizing sand cooling, the high-pressure centrifugal fan (air capacity 8000-25000m³/h) elevates the sand layer into a boiling state (300-600mm height), amplifying the contact area between sand and cold air by fivefold. This results in an unparalleled cooling efficiency of 30-80t/h, achieving a 40% energy savings compared to conventional vibrating cooling beds.
Stepped air distribution plate: A sophisticated porous ceramic hood (35% porosity), complemented by guide vanes, guarantees uniform airflow distribution (speed deviation <5%), preventing local overheating or agglomeration for flawless sand cooling.
Coordinated control of temperature and humidity:
The dual-fluid nozzle system is a marvel of precision, blending compressed air (0.6MPa) with atomized water (10-50μm particle size) to maintain sand humidity at 2.5±0.3% and reduce temperature to ≤35ºC, ensuring impeccable cooling.
Infrared thermal imager: This high-tech device offers real-time monitoring of the sand layer's temperature field (accuracy ±1ºC), enabling dynamic adjustments of fan speed and water spray volume to eliminate cooling dead zones completely.
Modular structural design:
Linear/vertical dual mode:
Linear type (L series): Engineered for sand processing lines with ample ground space, this series boasts a maximum processing capacity of 100t/h, making it ideal for high-volume operations.
Vertical type (V series): Featuring a sophisticated tower layout (occupying ≤8), this series is tailor-made for compact production lines with workshop heights exceeding 8 meters, optimizing space and efficiency.
Two-way unloading door: With an adjustable pneumatic gate valve (0-100% opening) and an unloading accuracy of ±2%, this feature allows left/right discharge direction customization, ensuring precision and flexibility.
2. Full-process integrated solution for foundry sand treatment
The Rapid Cooling Sand Cooler seamlessly integrates into the sand-sanding-screening-cooling-regeneration chain, forming an intelligent and holistic cooling unit:
Pretreatment of high-temperature old sand:
In collaboration with the vibrating conveyor, this system achieves preliminary cooling of 600ºC red sand (down to 150-200ºC), mitigating the risk of high-temperature deformation in the fluidized bed, thus preserving equipment integrity and performance.
Introducing our groundbreaking magnetic separation module, boasting a remarkable magnetic induction intensity of ≥1200Gs! This state-of-the-art feature effectively eradicates iron bean impurities, ensuring that the air distribution plate remains impeccably protected from any impact wear.
Closed-loop Water Circulation System:
Experience unmatched efficiency with our closed-loop system, where wastewater is ingeniously reclaimed post-treatment through a cyclone separator, achieving a staggering removal rate of over 95%. Combined with a state-of-the-art plate heat exchanger maintaining a temperature difference of ≤5ºC, this system boasts an impressive water saving rate of 70%!
Intelligent Dust Removal System:
Our cutting-edge dust removal system integrates seamlessly with a pulse bag dust collector at the top, achieving an extraordinary filtration efficiency of 99.9%! Emission concentrations are kept astonishingly low at <10mg/m³, while ensuring the working area remains pleasantly quiet with noise levels not exceeding ≤75dB(A).
3. Unrivaled Core Advantages & Economic Benefits
This machine stands in a league of its own, surpassing traditional cooling equipment through revolutionary leaps in efficiency, thanks to energy recovery and pioneering digital twin control.
Revolutionary Energy Consumption Optimization:
Witness the power of our heat pipe waste heat recovery technology, transforming exhaust gas heat (80-120ºC) into valuable hot water (50-70ºC). This innovation translates to a savings of over 800,000 yuan annually in steam costs, based on a robust processing capacity of 50t/h.
Our advanced combination of a variable frequency fan with a permanent magnet motor ensures power consumption per ton of sand is kept at a minimal ≤1.2kW·h, a remarkable 35% reduction compared to similar equipment.
Impressive Quality Improvement Data:
Achieve superior quality with a remarkable reduction in the fluctuation of the molding sand compaction rate from ±2.5% down to an exceptional ±0.8%. Moreover, the porosity defect rate in castings has plummeted by an incredible 75%!
Our innovative process increases the reuse rate of old sand to a phenomenal 90%, slashing the cost of replenishing new sand by an impressive 50%!
Enhanced Maintenance Convenience:
Experience unmatched convenience with our quick-detachable hood design, allowing for the replacement of a single hood in under 3 minutes!
Our observation window and maintenance platform are designed to meet stringent OSHA standards, facilitating seamless online maintenance and ensuring ultimate safety for all operations.
