Product Description
This remarkable machine specializes in the cooling of old green sand, ensuring that its temperature, humidity, and composition are perfectly uniform thanks to its dynamic movement capabilities. With its sleek, compact structure, this machine is engineered for stability and boasts low energy consumption while delivering an outstanding cooling effect. The high-pressure fan elevates the old sand into a boiling state, optimizing the cooling effect to its fullest potential. The adjustable unloading door allows precise control over the material content. Complemented by an automatic temperature and humidification system, along with a sophisticated blower, induced fan, and water system, this machine integrates seamlessly into a comprehensive and ideal old sand cooling unit.
Uniquely versatile, this machine can be configured for two distinct discharging methods—straight line and vertical—depending on its installation position. When placing an order, users can opt for both left and right unloading directions to suit their specific operational needs.
Within the foundry workshop's old sand regeneration process, the uniformity and efficiency of cooling high-temperature wet sand (80-150ºC, 3-8% moisture) are crucial for maximizing the reuse rate of molding sand and enhancing the quality of castings. Our double-disc stirring cooler offers an efficient, energy-saving, and customizable solution for the old sand cooling process. Utilizing the principles of boiling heat exchange and precise multi-parameter control technology, this article explores how our equipment is redefining energy efficiency standards in sand processing across diverse industries. We delve into the thermodynamic principles, process adaptability, intelligent control systems, and multi-industry applications that set this technology apart.
1. Technical principle and core component design
Capitalizing on the physical properties of old sand particles (particle size 0.15-1.2mm), this state-of-the-art equipment achieves technological breakthroughs with two pioneering core technologies: fluidized cooling and dynamic homogenization.
Boiling state heat exchange system:
A high-pressure centrifugal fan, with an air volume range of 8000-25000m³/h, elevates the sand layer to a suspended state, reaching a boiling height of 300-600mm. This significantly expands the contact area between sand particles and cold air by fivefold, propelling the cooling efficiency to an impressive 30-80t/h, representing a 40% energy saving over traditional vibrating cooling beds.
The stepped air distribution plate, complete with a porous ceramic hood (35% porosity) and guide vanes, ensures uniform airflow distribution (speed deviation <5%), effectively preventing localized overheating or particle agglomeration.
Coordinated control of temperature and humidity:
The dual-fluid nozzle system expertly utilizes a precise compressed air ratio (0.6MPa) and atomized water (10-50μm particle size) to maintain the old sand's humidity at 2.5±0.3% while reducing the temperature to a comfortable ≤35ºC.
An infrared thermal imager provides real-time monitoring of the sand layer's temperature field (accuracy ±1ºC), dynamically adjusting fan speed and water spray volume to eliminate cooling dead zones.
Modular structural design:
Linear/vertical dual mode:
The Linear type (L series) is perfect for sand processing lines with ample space, offering a maximum processing capacity of 100t/h.
In contrast, the Vertical type (V series) employs a tower layout (occupying ≤8), making it ideal for compact production lines with workshop heights exceeding 8m.
Equipped with a two-way unloading door, the pneumatic gate valve's opening is adjustable (0-100%), with unloading accuracy at ±2%, and customizable left/right discharge directions for tailored operations.
2. Full-process integrated solution for foundry sand treatment
This equipment seamlessly integrates into the sand-sanding-screening-cooling-regeneration process chain, forming an intelligent cooling unit that elevates foundry sand treatment to new heights.
Pretreatment of high-temperature old sand:
When linked with a vibrating conveyor, it facilitates the initial cooling of 600ºC red sand down to 150-200ºC, preventing high-temperature deformation of the fluidized bed and ensuring optimal cooling performance.
Our cutting-edge magnetic separation module, boasting a powerful magnetic induction intensity of ≥1200Gs, effortlessly eradicates iron bean impurities, thus safeguarding the air distribution plate from potential impact and wear.
Revolutionary Closed-Loop Water Circulation System:
Experience unparalleled water efficiency with our advanced system! Wastewater undergoes meticulous treatment through a high-efficiency cyclone separator, achieving a remarkable removal rate of over 95%. Paired with a precision plate heat exchanger maintaining a temperature difference of ≤5ºC, this innovation leads to a phenomenal water-saving rate of 70%!
Advanced Intelligent Dust Removal System:
At the pinnacle of dust management, our top-tier system incorporates a pulse bag dust collector with an astounding filtration efficiency of 99.9%! Emission concentrations are kept remarkably low at <10mg/m³, while the working area maintains a pleasantly quiet environment with noise levels kept at ≤75dB(A).
3. Compelling Comparison of Core Advantages and Economic Benefits
Embark on a new era of efficiency with our state-of-the-art machine, setting a new standard compared to traditional cooling equipment. Through advanced energy recovery and cutting-edge digital twin control, we achieve unparalleled leaps in efficiency:
Pioneering Energy Consumption Optimization:
Harness the power of our heat pipe waste heat recovery device, expertly converting exhaust gas heat (80-120ºC) into useful hot water (50-70ºC). This innovation translates into impressive cost savings, slashing more than 800,000 yuan in annual steam costs, based on a substantial processing capacity of 50t/h.
Our smart combination of a variable frequency fan paired with a permanent magnet motor ensures energy efficiency, achieving power consumption per ton of sand at ≤1.2kW·h, a remarkable 35% reduction compared to similar equipment.
Unmatched Quality Improvement Data:
Achieve superior quality with our system. The compaction rate fluctuation of molding sand has been significantly minimized from ±2.5% to an impressive ±0.8%. Moreover, witness a commendable 75% reduction in casting porosity defect rates.
Elevate your sustainability goals with a 90% reuse rate of old sand, contributing to a substantial 50% decrease in new sand replenishment costs.
Unparalleled Maintenance Convenience:
Our innovative quick-detachable hood design allows for seamless maintenance, enabling a single hood replacement in less than 3 minutes!
Designed with both safety and efficiency in mind, our observation window and maintenance platform adhere to OSHA standards, ensuring secure and convenient online maintenance support.
