Product Description
Introducing the Sand Cooler Multi-Cooler, a top-tier solution for the efficient cooling of used green sand. This state-of-the-art machine expertly maintains uniformity in temperature, humidity, and composition of the old sand, thanks to its robust design. Boasting a compact structure and stable operation, it minimizes energy consumption while delivering excellent cooling results. The high-pressure fan ensures the sand remains in a fluidized state, maximizing cooling efficiency. With an adjustable unloading door, you can precisely control material flow, ensuring optimal integration with the sand's automatic temperature and humidification systems. This sophisticated system, complete with a blower, induced fan, and water system, forms a comprehensive old sand cooling unit.
Our versatile machine can be customized based on installation requirements, offering two discharge configurations: straight line and vertical. Select the left or right unloading directions upon ordering to perfectly fit your operational needs.
In the realm of foundry workshops, the efficiency and uniformity of cooling high-temperature wet sand are pivotal. With temperatures ranging from 80-150ºC and water content between 3-8%, these factors significantly influence the reuse rate of molding sand and casting quality. Our innovative double-disc stirring cooler presents an efficient, energy-saving, and customizable solution through advanced boiling heat exchange and precise multi-parameter control technology. Herein, we delve into how this remarkable equipment sets new standards in energy efficiency for sand processing, grounded in thermodynamic principles, process adaptability, smart control systems, and applications across multiple industries.
1. Technical principle and core component design
Our breakthrough technology is founded on the physical properties of old sand particles (0.15-1.2mm). By harnessing two core innovations—fluidized cooling and dynamic homogenization—we revolutionize sand cooling processes:
Boiling state heat exchange system:
Employing a high-pressure centrifugal fan, this system propels the sand layer into a suspended state (boiling height of 300-600mm), which amplifies the contact surface between sand and cold air by fivefold. This results in a cooling capacity of 30-80t/h, achieving 40% energy savings compared to conventional vibrating cooling beds.
Our stepped air distribution plate features a porous ceramic hood (35% porosity) and guide vanes to ensure uniform airflow distribution (speed deviation under 5%), effectively preventing local overheating and sand clumping.
Coordinated control of temperature and humidity:
The dual-fluid nozzle system precisely administers compressed air (at 0.6MPa) and atomized water (particle size 10-50μm), maintaining sand humidity at 2.5±0.3% and reducing its temperature to ≤35ºC.
Utilizing an infrared thermal imager, we offer real-time monitoring of the sand layer's temperature field (accuracy within ±1ºC), enabling synchronized adjustments to fan speed and water spray volume, thereby eliminating cooling dead zones.
Modular structural design:
Linear/vertical dual mode:
Linear type (L series): This configuration is ideal for sand processing lines with generous ground space, boasting a maximum throughput of 100t/h.
Vertical type (V series): Featuring a tower layout, it is perfect for compact production lines with workshop heights exceeding 8 meters.
The two-way unloading door offers adjustable opening (0-100%), with unloading precision of ±2%. Customize the discharge direction to be either left or right, tailored to your needs.
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 optimizes the entire operation.
Pretreatment of high-temperature old sand:
When linked with a vibrating conveyor, the system facilitates the initial cooling of 600ºC red sand to a safer range of 150-200ºC, thus preventing fluidized bed deformation due to excessive heat.
Introducing a superior magnetic separation module with a robust magnetic induction intensity of no less than 1200Gs. This state-of-the-art module expertly eliminates iron bean impurities, ensuring unmatched protection for the air distribution plate against impact wear, thus enhancing overall operational efficiency.
Closed-loop water circulation system: A pioneering system designed to revolutionize water usage and enhance sustainability.
Experience a revolution in water conservation with our innovative wastewater treatment technology. Harnessing the power of a cyclone separator with a removal rate exceeding 95% and a plate heat exchanger maintaining a temperature difference of ≤5ºC, the system achieves an impressive 70% water saving rate by reusing wastewater efficiently.
Intelligent dust removal system: Innovations that redefine cleanliness and operational excellence.
At the pinnacle of innovation, the top integrates seamlessly with a pulse bag dust collector, boasting a filtration efficiency of 99.9%. Emission concentrations are meticulously controlled to remain under 10mg/m³, while ensuring noise levels in the working area do not exceed a comfortable 75dB(A), creating a harmonious work environment.
3. A comparative analysis of core advantages and economic benefits: Discover unparalleled advancements and financial gains.
Our cutting-edge machine eclipses traditional cooling equipment, achieving remarkable efficiency through advanced energy recovery mechanisms and sophisticated digital twin control technologies, elevating performance to new heights.
Energy consumption optimization: Breakthroughs that redefine sustainable energy use.
Harness the transformative power of the heat pipe waste heat recovery device, which skillfully converts exhaust gas heat ranging from 80-120ºC into valuable hot water at 50-70ºC. This innovation translates into significant savings, cutting steam costs by over 800,000 yuan annually, based on a substantial processing capacity of 50t/h.
Leveraging the synergy of a variable frequency fan with a permanent magnet motor, our system dramatically reduces power consumption to an impressive ≤1.2kW·h per ton of sand, delivering a significant 35% reduction in energy use compared to similar equipment.
Quality improvement data: Elevate your standards with breakthrough metrics.
Witness a remarkable enhancement in quality with the compaction rate fluctuation of molding sand significantly minimized from ±2.5% to an astounding ±0.8%. Additionally, the porosity defect rate in castings has been slashed by an impressive 75%, setting new benchmarks in quality assurance.
Achieve outstanding material efficiency with the reuse rate of old sand soaring to an impressive 90%. This remarkable achievement cuts the cost of replenishing new sand by a substantial 50%, showcasing exceptional resource management.
Maintenance convenience: Designed for effortless and efficient upkeep.
The innovative quick-detachable hood design enables rapid maintenance, allowing a single hood replacement in less than 3 minutes, ensuring minimal downtime and maximizing productivity.
Adhering to the highest safety standards, our observation window and maintenance platform fully comply with OSHA regulations, supporting seamless online maintenance, enhancing both safety and operational efficiency.
