Product Description
Introducing our cutting-edge Efficient Sand Cooler Multi-Cooler, a pinnacle of advanced technology designed to revolutionize the cooling of old green sand. This machine ensures uniformity in temperature, humidity, and composition of the sand with remarkable precision. Boasting a compact and stable structure, it offers low energy consumption while delivering an outstanding cooling effect. The high-pressure fan elevates the sand into a boiling state, optimizing cooling. The adjustable unloading door precisely controls material output. An autonomous system comprising temperature and humidification controls, along with a blower, induced fan, and water system, form a seamless and exemplary sand cooling solution.
Our versatile machine supports two distinct discharging configurations: the streamlined straight line type and the efficient vertical type. When placing an order, clients can specify their preference for left or right unloading directions to best suit their operational needs.
In the realm of foundry workshops, our innovative cooling solutions redefine the standard for high-temperature wet sand processing (80-150ºC and 3-8% moisture). This cutting-edge double-disc stirring cooler offers an energy-efficient and customizable approach to sand cooling. Utilizing boiling heat exchange and precision multi-parameter control, this equipment sets a new benchmark in energy efficiency. This comprehensive analysis highlights its impact across thermodynamic principles, process adaptability, intelligent control systems, and its diverse applications across multiple industries.
1. Technical principle and core component design
Harnessing the unique physical properties of old sand particles, this equipment achieves groundbreaking advancements with two proprietary technologies: fluidized cooling and dynamic homogenization.
Boiling state heat exchange system:
Our high-pressure centrifugal fan operates at an air volume of 8000-25000m³/h, lifting the sand to a boiling height of 300-600mm. This increases the contact area with cold air fivefold, achieving a cooling efficiency of 30-80t/h while delivering a 40% energy savings over traditional methods.
Our stepped air distribution plate features a porous ceramic hood with 35% porosity, coupled with guide vanes to ensure consistent airflow distribution with speed deviation under 5%, preventing local overheating and clumping.
Coordinated control of temperature and humidity:
Our dual-fluid nozzle system expertly mixes compressed air at 0.6MPa with atomized water, controlling humidity to 2.5±0.3% and reducing temperature to ≤35ºC, for perfectly conditioned sand.
Equipped with an infrared thermal imager for real-time monitoring, this system adjusts fan speed and water spray volumes precisely, eliminating cooling dead zones and maintaining temperature accuracy within ±1ºC.
Modular structural design:
Linear/vertical dual mode:
The Linear type (L series) is engineered for expansive sand processing lines, accommodating up to 100t/h processing capacity.
The Vertical type (V series) features a space-efficient tower design, ideal for compact production lines in workshops with a height greater than 8m.
Our innovative two-way unloading door with a pneumatic gate valve allows for adjustable openings from 0-100%, ensuring precise unloading with an accuracy of ±2%, customizable for left/right direction.
2. Full-process integrated solution for foundry sand treatment
This advanced equipment seamlessly integrates into the sand-sanding-screening-cooling-regeneration process chain, forming a high-tech, intelligent cooling unit.
Pretreatment of high-temperature old sand:
In synergy with the vibrating conveyor, it initially cools red-hot sand at 600ºC to a manageable 150-200ºC, safeguarding the fluidized bed from high-temperature deformation.
Our cutting-edge magnetic separation module, boasting a magnetic induction intensity of ≥1200Gs, excels at removing iron bean impurities. This not only ensures the longevity of our air distribution plate by preventing impact wear but also enhances the overall efficiency and reliability of the system.
Introducing our state-of-the-art Closed-loop Water Circulation System:
Innovatively designed, our system treats wastewater using a cyclone separator with an impressive removal rate of over 95%. Coupled with a precision plate heat exchanger (temperature difference kept within ≤5ºC), it achieves a remarkable 70% water saving rate, setting new standards in eco-friendly operations.
Experience unparalleled performance with our Intelligent Dust Removal System:
At the heart of our system lies a high-efficiency pulse bag dust collector, achieving filtration efficiency of 99.9%. The emission concentration is kept minimal at <10mg/m³, while noise levels remain comfortable at ≤75dB(A) in the working area, ensuring a cleaner and quieter work environment.
3. Explore the Comparative Edge and Economic Benefits:
Our advanced machine redefines efficiency by integrating energy recovery systems and cutting-edge digital twin control, surpassing traditional cooling equipment in performance and sustainability.
Focus on Energy Consumption Optimization:
Ingeniously, our heat pipe waste heat recovery device transforms exhaust gas heat (80-120ºC) into valuable hot water (50-70ºC), resulting in substantial savings of over 800,000 yuan in annual steam costs, based on a processing capacity of 50t/h.
With the strategic usage of variable frequency fans and permanent magnet motors, the power consumption per ton of sand is reduced to an impressive ≤1.2kW·h, marking a 35% decrease compared to similar equipment, epitomizing energy efficiency.
Delve into Quality Improvement Data:
We've successfully minimized the fluctuation of the molding sand's compaction rate from ±2.5% to a mere ±0.8%. Additionally, the porosity defect rate of castings has been dramatically reduced by 75%, significantly enhancing product quality.
The reuse rate of old sand has soared to 90%, leading to a substantial 50% reduction in the cost of replenishing new sand, ensuring economic efficiency and sustainability.
Unmatched Maintenance Convenience:
Our revolutionary quick-detachable hood design allows for swift replacements, with a single hood change completed in under 3 minutes, minimizing downtime and enhancing productivity.
Designed with safety and efficiency in mind, the observation window and maintenance platform not only meet OSHA standards but also support seamless online maintenance, ensuring consistent operational performance.
