Product Description
This machine is ingeniously crafted for the precise cooling of previously used green sand. Through its robust movement, it ensures that temperature, humidity, and composition of the sand are consistently balanced. Designed with a compact and stable structure, it promises low energy consumption and delivers top-tier cooling performance. An advanced high-pressure fan elevates the sand to a fluid-like boiling state, optimizing the cooling results. The adjustable unloading door allows precise control over material discharge. Together with the automatic temperature and humidification system, and the coordination of blower, induced fan, and water system, this device forms an impeccable and complete cooling unit for old sand.
Tailored to your facility’s specific needs, this machine offers versatile discharge capabilities with both straight line and vertical configurations. When ordering, consider utilizing both left and right unloading directions to maximize operational efficiency.
In the world of foundry workshops, the uniform and efficient cooling of high-temperature wet sand (80-150ºC, containing 3-8% moisture) is crucial. It directly influences the molding sand's reusability and the quality of the final castings. Our double-disc stirring cooler offers an unrivaled, energy-efficient, customizable solution, employing boiling heat exchange and precise multi-parameter control. Explore how this innovative equipment is redefining energy standards in sand processing through advanced thermodynamic principles, adaptive processes, intelligent control systems, and diverse industry applications.
1. Technical principle and core component design
Leveraging the unique physical properties of old sand particles (0.15-1.2mm), this equipment breaks new ground with two pivotal technologies: fluidized cooling and dynamic homogenization:
Boiling state heat exchange system:
A high-pressure centrifugal fan with an airflow capacity of 8000-25000m³/h propels the sand into a suspended, boiling state (300-600mm height). This dramatically increases the contact area between sand particles and cold air by up to five times, achieving a cooling efficiency of 30-80t/h, while boasting a 40% energy savings over conventional vibrating cooling beds.
With a stepped air distribution plate featuring a 35% porous ceramic hood and guide vanes, the system guarantees uniform airflow distribution (speed deviation <5%), mitigating risks of local overheating or particle agglomeration.
Coordinated control of temperature and humidity:
The dual-fluid nozzle system precisely blends compressed air (0.6MPa) with atomized water (particle size 10-50μm), maintaining sand humidity at 2.5±0.3% and reducing temperature to ≤35ºC effectively.
Equipped with infrared thermal imaging, it offers real-time temperature field monitoring (accuracy ±1ºC). This feature dynamically adjusts fan speeds and water spray volumes, ensuring there are no cooling dead spots.
Modular structural design:
Linear/vertical dual mode:
The Linear type (L series) is perfect for sand processing lines with generous ground space, boasting a processing capacity of up to 100t/h.
The Vertical type (V series), designed in a tower layout, is ideal for compact production lines, requiring a workshop height exceeding 8m.
With a two-way unloading door, the adjustable pneumatic gate valve (0-100%) ensures unloading precision at ±2%, with customizable left/right discharge direction.
2. Full-process integrated solution for foundry sand treatment
Skillfully integrated into the sand treatment process chain, it incorporates sanding, screening, cooling, and regeneration to create an intelligent cooling unit.
Pretreatment of high-temperature old sand:
In conjunction with the vibrating conveyor, it initially cools 600ºC red sand down to 150-200ºC, preventing high-temperature deformation of the fluidized bed, thus safeguarding the equipment's longevity and performance.
Introducing our state-of-the-art magnetic separation module, designed with a powerful magnetic induction intensity of ≥1200Gs. This advanced module excels at eliminating iron bean impurities, ensuring robust protection for the air distribution plate against impact and wear, paving the way for uninterrupted, long-lasting performance.
Revolutionary Closed-Loop Water Circulation System:
Experience sustainable innovation with our system where wastewater undergoes meticulous treatment via a cyclone separator boasting a remarkable removal rate exceeding 95%. Combined with a highly efficient plate heat exchanger ensuring a temperature difference within ≤5ºC, this system proudly achieves a groundbreaking water saving rate of 70%, embodying the pinnacle of resource conservation.
Cutting-edge Intelligent Dust Removal System:
Our top-tier system features an integrated pulse bag dust collector with an impressive filtration efficiency of 99.9%. Emission concentrations are expertly controlled to stay below 10mg/m³, while the operational area maintains a comfortable noise level of ≤75dB(A), ensuring a safe and serene working environment.
3. Unveiling Core Advantages and Unmatched Economic Benefits:
Embark on a journey of advanced efficiency with our innovative machine, setting new standards when compared to traditional cooling equipment. Through strategic energy recovery and sophisticated digital twin control, we deliver remarkable enhancements in operational performance.
Pioneering Energy Consumption Optimization:
Our cutting-edge heat pipe waste heat recovery device ingeniously converts exhaust gas heat ranging from 80-120ºC into hot water at 50-70ºC. This ingenious process results in annual steam cost savings exceeding 800,000 yuan, calculated on a processing capacity of 50t/h, epitomizing cost-effective energy efficiency.
Utilizing the synergy of a variable frequency fan alongside a permanent magnet motor, our system ensures that the power consumption per ton of sand is impressively reduced to ≤1.2kW·h, marking a substantial 35% decrease compared to similar equipment, reflecting our commitment to energy conservation.
Remarkable Quality Improvement Data:
Our innovative solutions have significantly reduced the fluctuation of the compaction rate of molding sand from ±2.5% to a mere ±0.8%. Additionally, the porosity defect rate of castings has been slashed by an impressive 75%, showcasing our dedication to superior quality enhancements.
Effortlessly elevating sustainability, the reuse rate of old sand has been dramatically increased to 90%, while the costs associated with replenishing new sand have been halved by 50%, demonstrating our commitment to both economic and environmental benefits.
Unmatched Convenience in Maintenance:
Our innovative quick-detachable hood design allows for seamless maintenance, enabling the replacement of a single hood in under 3 minutes, facilitating unparalleled convenience and minimizing downtime.
Equipped with an observation window and maintenance platform that adhere to OSHA standards, our system supports online maintenance, ensuring that safety and efficiency go hand in hand.
