Product Description
Introducing our Versatile Sand Cooler Multi-Cooler, designed with precision to cater to the cooling requirements of old green sand. Experience uniformity like never before, as the thorough movement harmonizes the temperature, humidity, and composition of the old sand. Boasting a compact design, this machine ensures stable operation while minimizing energy usage, delivering an impressive cooling effect. The inclusion of a high-pressure fan elevates the old sand into a boiling state, maximizing the cooling efficacy. Furthermore, the adjustable unloading door offers precise control over the material quantity in salt. The machine seamlessly integrates with the old sand's automatic temperature and humidification system, along with the blower, induced fan, and water system, to form a comprehensive and ideal old sand cooling unit.
Customize your sand cooling experience with our versatile machine, available in two distinct discharging methods: straight line type and vertical type. When placing your order, choose from left or right unloading directions to suit your operational needs.
In the realm of foundry workshops, achieving uniformity and high efficiency in cooling high-temperature wet sand (ranging from 80-150ºC with 3-8% water content) is pivotal for enhancing the reuse rate of molding sand and the quality of castings. Our double-disc stirring cooler offers an innovative, energy-efficient, and customizable solution for the old sand cooling process. Leveraging boiling heat exchange and multi-parameter precision control technologies, this equipment revolutionizes energy efficiency standards in sand processing. Delve into our comprehensive analysis, exploring the thermodynamic principles, adaptability, intelligent control systems, and multi-industry applications that set new benchmarks.
1. Technical principle and core component design
Harnessing the physical properties of old sand particles (particle size 0.15-1.2mm), our equipment achieves groundbreaking advancements through two core technologies: fluidized cooling and dynamic homogenization:
Boiling state heat exchange system:
Our high-pressure centrifugal fan, with an impressive air volume range of 8000-25000m³/h, elevates the sand layer to a suspended boiling state (300-600mm height), significantly expanding the contact area between sand particles and cool air by fivefold. Experience cooling efficiency of 30-80t/h, achieving a remarkable 40% energy-saving compared to traditional vibrating cooling beds.
The stepped air distribution plate features a porous ceramic hood (35% porosity) that collaborates with guide vanes, ensuring uniform airflow distribution (speed deviation <5%) and preventing local overheating or agglomeration.
Coordinated control of temperature and humidity:
The dual-fluid nozzle system precisely balances compressed air (0.6MPa) and atomized water (particle size 10-50μm), maintaining the old sand's humidity at 2.5±0.3% and reducing the temperature to ≤35ºC.
Our infrared thermal imager provides real-time monitoring of the sand layer's temperature field (accuracy ±1ºC). It synergistically adjusts fan speed and water spray volume, effectively eliminating cooling dead corners.
Modular structural design:
Linear/vertical dual mode:
The Linear type (L series) is ideal for sand processing lines with abundant ground space, boasting a maximum processing capacity of 100t/h.
The Vertical type (V series) features a tower layout (occupying ≤8), perfect for compact production lines with workshop heights exceeding 8m.
Featuring a two-way unloading door, our pneumatic gate valve offers adjustable openings (0-100%), delivering unloading accuracy of ±2% with customizable left/right discharge directions.
2. Full-process integrated solution for foundry sand treatment
Our equipment seamlessly integrates into the sand-sanding-screening-cooling-regeneration process chain, creating an intelligent cooling unit that enhances operational efficiency and performance.
Pretreatment of high-temperature old sand:
When combined with a vibrating conveyor, our system efficiently initiates the cooling of 600ºC red sand (down to 150-200ºC), preventing high-temperature deformation of the fluidized bed.
Elevate your operational efficiency with our advanced magnetic separation module, boasting an impressive magnetic induction intensity of no less than 1200Gs. This feature ensures the meticulous removal of iron bean impurities, effectively safeguarding your air distribution plate from any potential impact wear.
Unveiling an innovative closed-loop water circulation system:
Our state-of-the-art wastewater recycling process involves a cyclone separator with a stellar removal rate exceeding 95%, and a top-notch plate heat exchanger that maintains a temperature difference of no more than 5ºC. All of these contribute to an exceptional 70% water saving rate, making sustainability a reality.
Discover the power of our intelligent dust removal system:
This system's pinnacle feature is its integrated pulse bag dust collector, achieving an outstanding filtration efficiency of 99.9%. With an emission concentration below 10mg/m³, it operates at a working area noise level of ≤75dB(A), ensuring a tranquil and clean environment.
3. Unveiling the core advantages and remarkable economic benefits
Step into a new era of cooling technology with our equipment, as it eclipses traditional systems by harnessing energy recovery and leveraging the cutting-edge digital twin control for unprecedented efficiency gains:
Revolution in energy consumption optimization:
Thanks to the integration of our heat pipe waste heat recovery device, exhaust gas heat (ranging between 80-120ºC) is ingeniously converted into hot water (50-70ºC). This breakthrough innovation saves over 800,000 yuan annually in steam costs, based on a processing capacity of 50t/h.
An exquisite synergy of our variable frequency fan and permanent magnet motor achieves power consumption per ton of sand at a remarkable ≤1.2kW·h, slashing energy use by 35% compared to similar equipment.
Unveiling quality improvement insights:
Witness a significant reduction in the fluctuation of the molding sand's compaction rate from ±2.5% down to ±0.8%, while achieving a remarkable 75% decrease in casting porosity defects.
Harness the power of increased efficiency with a 90% reuse rate of old sand, which results in a 50% reduction in the cost of replenishing new sand.
Enhancing maintenance convenience:
Featuring a quick-detachable hood design, you can replace a single hood in under 3 minutes, optimizing your maintenance routine.
Our observation window and maintenance platform are designed to comply with OSHA standards, providing seamless support for online maintenance activities.
