Product Description
Discover the ultimate solution for the cooling of used green sand with our Tailored Sand Cooler Multi-Cooler. Engineered for excellence, this machine ensures homogenous temperature, humidity, and composition of recycled sand through its innovative design. Experience seamless operation with its compact, stable framework that boasts low energy consumption and exceptional cooling efficiency. Powered by a high-pressure fan, the old sand is brought to a boiling state, achieving unparalleled cooling performance. The adjustable unloading door precisely manages material levels, while the automatic temperature and humidification system, complemented by a blower, induced fan, and water system, forms a comprehensive and ideal sand cooling unit.
Flexible and adaptable, this advanced machine offers two configurations for material discharge: straight line and vertical. Customize your operations by specifying left or right unloading directions upon ordering, ensuring optimal integration into your existing systems.
In the foundry workshop, the regeneration of old sand is crucial for enhancing both the reuse rate of molding sand and the quality of castings. With temperatures ranging from 80-150ºC and water content of 3-8%, our double-disc stirring cooler delivers an energy-efficient and customizable solution for cooling high-temperature wet sand. Utilizing boiling heat exchange mechanisms and precise multi-parameter control technology, this equipment revolutionizes the energy efficiency standards in sand processing. Delve into an in-depth analysis of its impact on thermodynamic principles, process adaptability, intelligent control systems, and multi-industry applications, redefining the landscape of sand treatment processes.
1. Technical principle and core component design
Harnessing the unique physical properties of old sand particles (0.15-1.2mm), our equipment achieves groundbreaking advancements with two core technologies: fluidized cooling and dynamic homogenization:
Boiling state heat exchange system:
A high-pressure centrifugal fan (air volume 8000-25000m³/h) elevates the sand layer to a suspended state (boiling height 300-600mm), significantly enlarging the contact area between sand particles and cold air by five times. This results in a cooling efficiency of 30-80t/h, offering a remarkable 40% energy saving over traditional vibrating cooling beds.
The advanced stepped air distribution plate, equipped with a porous ceramic hood (porosity 35%) and guide vanes, ensures even airflow distribution (speed deviation <5%), preventing local overheating or clumping of sand.
Coordinated control of temperature and humidity:
Our dual-fluid nozzle system expertly balances compressed air (0.6MPa) and atomized water (particle size 10-50μm) to maintain the old sand's humidity at 2.5±0.3% and reduce its temperature to ≤35ºC.
An infrared thermal imager provides real-time monitoring of the sand layer's temperature field (accuracy ±1ºC), facilitating synchronized adjustments in fan speed and water spray volume to eliminate cooling dead zones.
Modular structural design:
Linear/vertical dual mode:
The Linear type (L series) is ideal for sand processing lines with ample ground space, boasting a maximum processing capacity of 100t/h.
The Vertical type (V series), featuring a tower layout (occupying ≤8), is perfect for compact production lines with workshop heights exceeding 8m.
Our innovative two-way unloading door offers adjustable pneumatic gate valve openings (0-100%) for precise unloading accuracy (±2%), with customizable left/right discharge directions.
2. Full-process integrated solution for foundry sand treatment
Integrate this equipment seamlessly into your sand-sanding-screening-cooling-regeneration process chain to build an intelligent cooling unit that enhances overall efficiency and productivity.
Pretreatment of high-temperature old sand:
In conjunction with the vibrating conveyor, it initially cools 600ºC red sand (reducing it to 150-200ºC), thereby preventing high-temperature deformation of the fluidized bed, ensuring smooth downstream processing.
Our revolutionary magnetic separation module, boasting a magnetic induction intensity of ≥1200Gs, effectively eradicates iron bean impurities. This ensures the pristine protection of the air distribution plate from detrimental impact wear.
Efficient Closed-loop Water Circulation System:
Our advanced system promotes wastewater reuse, skillfully treated through a cyclone separator with a >95% removal rate, and processed by a state-of-the-art plate heat exchanger maintaining a temperature difference of ≤5ºC. This leads to an impressive 70% savings in water usage.
Sophisticated Intelligent Dust Removal System:
The system's apex integrates a highly efficient pulse bag dust collector, achieving a superior filtration efficiency of 99.9%. Emission concentration is kept under <10mg/m³, while ensuring noise levels in the workspace do not exceed ≤75dB(A).
3. Key Comparative Advantages and Economic Benefits that Set Us Apart
Our cutting-edge machine, compared to conventional cooling solutions, signifies a monumental leap in efficiency by leveraging energy recovery and employing advanced digital twin control systems:
Remarkable Energy Consumption Optimization:
The innovative heat pipe waste heat recovery device revolutionizes energy savings by converting exhaust gas heat (80-120ºC) into hot water (50-70ºC). This translates into saving over 800,000 yuan annually in steam costs, calculated based on a robust processing capacity of 50t/h.
By integrating a variable frequency fan with a high-efficiency permanent magnet motor, we achieve a power consumption per ton of sand of ≤1.2kW·h, which is a remarkable 35% reduction compared to similar technologies.
Unmatched Quality Improvement Metrics:
Experience a significant enhancement in quality as the compaction rate fluctuation of molding sand is minimized from ±2.5% to ±0.8%, and the porosity defect rate in castings is reduced by an impressive 75%;
Our commitment to sustainability is evident with the reuse rate of old sand surging to 90%, drastically cutting the cost of new sand replenishment by 50%.
Maintenance Made Effortlessly Convenient:
The innovative quick-detachable hood design allows for swift replacements, taking less than 3 minutes for a single hood;
Our meticulous design, featuring an observation window and maintenance platform, adheres to OSHA standards, ensuring safety and facilitating seamless online maintenance support.
