Product Description
Introducing the Sand Cooler Multi-Cooler, your ultimate solution for the effective cooling of old green sand. Engineered for excellence, this machine ensures optimal temperature, humidity, and composition uniformity through a meticulous movement process. Its compact structure promises stability, minimal energy consumption, and superior cooling performance. The high-pressure fan elevates the sand to a boiling state, guaranteeing an unparalleled cooling effect. With an adjustable unloading door, you can precisely control the material flow. This system, along with its automatic temperature and humidity controls, blower, induced fan, and water system, forms a comprehensive and ideal unit for cooling old sand.
This versatile machine offers flexibility with two discharging methods based on installation position: straight-line or vertical type. When placing your order, you can choose between left or right unloading directions to fit your specific operational needs.
In the intricate process of foundry workshop sand regeneration, the Sand Cooler Multi-Cooler shines by enhancing cooling uniformity and efficiency of high-temperature wet sand (80-150ºC, 3-8% moisture). These factors directly impact the mold sand reuse rate and casting quality. Our double-disc stirring cooler stands out by delivering an energy-saving, customizable solution via boiling heat exchange and precise multi-parameter control technology. Dive into an in-depth exploration of how this groundbreaking equipment redefines energy efficiency standards in sand processing from thermodynamics, process adaptability, intelligent control systems to multi-industry applications.
1. Technical principle and core component design
Harnessing the unique properties of old sand particles (0.15-1.2mm), our equipment pioneers advances through two revolutionary technologies: fluidized cooling and dynamic homogenization.
Boiling state heat exchange system:
Our state-of-the-art high-pressure centrifugal fan (8000-25000m³/h) elevates the sand layer to a suspended 'boiling' state (300-600mm), drastically increasing contact between sand particles and cold air by fivefold. This results in impressive cooling efficiencies between 30-80t/h, outperforming traditional vibrating cooling beds with a 40% energy-saving advantage.
Stepped air distribution plate: The innovative porous ceramic hood (35% porosity) and guide vanes work in tandem to ensure uniform airflow distribution (deviation <5%), effectively preventing local overheating or agglomeration.
Coordinated control of temperature and humidity:
Our dual-fluid nozzle system uses a precise blend of compressed air (0.6MPa) and atomized water (10-50μm) to maintain sand humidity at 2.5±0.3%, while reducing temperature to a comfortable ≤35ºC.
Infrared thermal imager: This device ensures real-time temperature field monitoring (accuracy ±1ºC), allowing for dynamic adjustments to fan speed and water spray volume, eliminating cooling inefficiencies.
Modular structural design:
Linear/vertical dual mode:
Linear type (L series): Perfect for expansive sand processing lines, offering a robust maximum processing capacity of 100t/h.
Vertical type (V series): Featuring a tower layout that conserves space (occupying ≤8), ideal for compact production lines with a workshop height exceeding 8m.
Two-way unloading door: Adjustable pneumatic gate valve (0-100%) ensures precision unloading (accuracy ±2%), with customizable left/right discharge directions to suit your operation.
2. Full-process integrated solution for foundry sand treatment
Our comprehensive equipment seamlessly integrates into the sand-sanding-screening-cooling-regeneration chain, creating an intelligent, streamlined cooling unit.
Pretreatment of high-temperature old sand:
When synchronized with a vibrating conveyor, it efficiently reduces the initial temperature of 600ºC red sand to a manageable 150-200ºC, preventing high-temperature deformation of the fluidized bed.
Introducing our state-of-the-art magnetic separation module, boasting a magnetic induction intensity of 1200 Gs and beyond. This powerhouse effectively eradicates iron bean impurities, offering unparalleled protection to the air distribution plate against any impact wear.
Revolutionizing efficiency with our Closed-loop water circulation system:
Experience cutting-edge wastewater management. After meticulous treatment by a cyclone separator achieving a removal rate of over 95%, and a plate heat exchanger maintaining a temperature difference of no more than 5ºC, our system ensures water is reused efficiently, achieving a remarkable water-saving rate of 70%.
Discover our Intelligent dust removal system:
At the pinnacle of dust management, the top of our system is seamlessly integrated with a pulse bag dust collector, delivering an impressive filtration efficiency of 99.9%. Emission concentrations are kept under 10mg/m³, while noise levels in the working area remain comfortably below 75dB(A).
3. Unveiling the Core Advantages and Economic Benefits:
Witness a transformative leap in efficiency with our machine. Unlike traditional cooling equipment, ours excels through advanced energy recovery and the groundbreaking digital twin control:
Pioneering Energy Consumption Optimization:
Our innovative heat pipe waste heat recovery device transforms exhaust gas heat, ranging from 80-120ºC, into useful hot water between 50-70ºC. This ingenuity translates into savings exceeding 800,000 yuan annually in steam costs, based on a substantial processing capacity of 50t/h.
With the synergy of a variable frequency fan and a permanent magnet motor, our system reduces power consumption per ton of sand to an impressive ≤1.2kW·h, marking a remarkable 35% reduction compared to similar equipment.
Exceptional Quality Improvement Data:
Marvel at the precision of our molding sand compaction rate, now stabilized from a previous fluctuation of ±2.5% to a mere ±0.8%. Additionally, the casting porosity defect rate has impressively dropped by 75%, reflecting our commitment to excellence.
Our innovation has propelled the reuse rate of old sand to a commendable 90%, slashing the costs of replenishing new sand by an incredible 50%.
Enhanced Maintenance Convenience:
Our advanced quick-detachable hood design is engineered for efficiency, allowing for the replacement of a single hood in under three minutes, ensuring maximum uptime and convenience.
Equipped with user-friendly features, our observation window and maintenance platform are fully compliant with OSHA standards, facilitating seamless online maintenance and ensuring safety and ease.
