Product Description
Introducing the game-changer in sand cooling technology – the Rapid Cooling Sand Cooler Multi-Cooler. Engineered specifically for the rejuvenation of old green sand, this machine ensures even distribution of temperature, moisture, and composition, thanks to its robust movement. Compact yet powerful, it boasts a stable operation with minimal energy consumption while delivering an exceptional cooling effect. The high-pressure fan elevates the sand to a boiling state, optimizing the cooling process. With adjustable unloading doors, you can precisely control the material discharge. This innovative machine, coupled with an automatic temperature and moisture control system, along with a blower, induced fan, and water system, forms a flawless and comprehensive old sand cooling solution.
Tailored to meet diverse installation requirements, the versatile Rapid Cooling Sand Cooler is available in two discharging configurations: straight line and vertical types. When placing your order, consider both the left and right unloading directions to match your specific setup needs.
In the dynamic environment of foundry workshops, the uniform cooling and efficiency of high-temperature wet sand (temperatures ranging from 80-150ºC with 3-8% moisture content) are crucial for enhancing the reusability of molding sand and the quality of castings. The innovative double-disc stirring cooler offers a high-efficiency, energy-conscious, and customizable solution for cooling old sand through cutting-edge boiling heat exchange and multi-parameter controlled technology. This comprehensive analysis will delve into how this equipment is revolutionizing the energy efficiency benchmarks of the sand processing domain from the perspectives of thermodynamic principles, process adaptability, intelligent control systems, and multi-industry applications.
1. Technical principle and core component design
Capitalizing on the unique physical properties of old sand particles (ranging from 0.15-1.2mm), our cutting-edge equipment achieves technological advancements via two groundbreaking technologies: fluidized cooling and dynamic homogenization.
Boiling state heat exchange system:
With a powerful high-pressure centrifugal fan (delivering an air volume of 8000-25000m³/h), the sand layer is elevated to a suspended, boiling state (rising between 300-600mm). This maximizes the contact surface between sand particles and cold air fivefold, achieving a cooling efficiency that processes an impressive 30-80t/h, while being 40% more energy-efficient than conventional vibrating cooling beds.
Stepped air distribution plate: The innovative porous ceramic hood (porosity of 35%) works in harmony with guide vanes to ensure flawless airflow distribution (speed deviation maintained below 5%), preventing local overheating or sand agglomeration.
Coordinated control of temperature and humidity:
Dual-fluid nozzle system: With precision-engineered ratios of compressed air (0.6MPa) and atomized water (particle size of 10-50μm), the old sand's humidity is expertly maintained at 2.5±0.3%, and its temperature is efficiently reduced to ≤35ºC.
Infrared thermal imager: This sophisticated gadget provides real-time monitoring of the sand layer's temperature field (with an accuracy of ±1ºC), allowing for the synchronized adjustment of fan speed and water spray volume, ensuring the elimination of cooling dead zones.
Modular structural design:
Linear/vertical dual mode:
Linear type (L series): Ideal for sand processing lines with abundant ground space, it offers a substantial processing capacity of up to 100t/h.
Vertical type (V series): With a smart tower layout (occupying ≤8), it is perfect for compact production lines where the workshop height exceeds 8m.
Two-way unloading door: This feature allows for adjustable pneumatic gate valve opening (0-100%), boasting unloading precision of ±2%, and accommodates customizable left/right discharge directions.
2. Full-process integrated solution for foundry sand treatment
Our equipment seamlessly integrates into the full sand-sanding-screening-cooling-regeneration process chain, crafting an intelligent cooling paradigm.
Pretreatment of high-temperature old sand:
In collaboration with the vibrating conveyor, it efficiently performs initial cooling of 600ºC red sand (down to 150-200ºC), preventing high-temperature deformation of the fluidized bed.
The advanced magnetic separation module, boasting an impressive magnetic induction intensity of ≥1200Gs, expertly rids your processes of iron bean impurities. This not only enhances the purity of your end product but also safeguards the air distribution plate from potential impact and wear, ensuring longevity and reliability.
Innovative Closed-Loop Water Circulation System:
Experience unparalleled efficiency as wastewater is ingeniously treated through a cyclone separator, achieving a remarkable removal rate of over 95%. Coupled with a state-of-the-art plate heat exchanger that maintains a temperature difference of ≤5ºC, this system reuses water with an impressive saving rate of 70%, championing sustainability.
Cutting-Edge Intelligent Dust Removal System:
At the pinnacle of this system is an integrated pulse bag dust collector, delivering an astounding filtration efficiency of 99.9%. This ensures emission concentrations remain below 10mg/m³ and maintains workplace noise levels at a comfortable ≤75dB(A), promoting a healthier work environment.
3. Comprehensive Comparison of Core Advantages and Economic Benefits
This machine offers a revolutionary leap in efficiency over traditional cooling equipment, accomplished through cutting-edge energy recovery techniques and sophisticated digital twin control.
Pioneering Energy Consumption Optimization:
Utilizing a highly efficient heat pipe waste heat recovery device, the system expertly converts exhaust gas heat (80-120ºC) into reusable hot water (50-70ºC). This innovation yields substantial savings, exceeding 800,000 yuan annually in steam costs, based on a processing capacity of 50t/h.
Through the strategic combination of a variable frequency fan and a permanent magnet motor, power consumption per ton of sand is reduced to an impressive ≤1.2kW·h, marking a significant 35% reduction compared to similar equipment.
Exceptional Quality Improvement Data:
Our technological advancements have reduced the fluctuation of the compaction rate of molding sand from ±2.5% to a precise ±0.8%. Additionally, we've slashed the porosity defect rate of castings by a striking 75%, elevating overall product quality.
The reuse rate of old sand has been dramatically increased to 90%, consequently slashing the cost of replenishing new sand by a substantial 50%, optimizing resource utilization.
Enhanced Maintenance Convenience:
Featuring a quick-detachable hood design, replacing a single hood is astonishingly swift, taking less than 3 minutes, minimizing downtime and maximizing efficiency.
Our observation window and maintenance platform are designed to meet OSHA standards, providing robust support for seamless online maintenance, prioritizing safety and accessibility.
