Product Description
Introducing our groundbreaking series of continuous coolers! These ingenious machines effortlessly transform loose old sand into a state of perfection. By utilizing the robust force of a high-pressure fan, the sand enters a boiling state within the cooling bed. As it journeys along the meandering coil cooling pipe, the powerful suction and cooling water work in tandem to fully cool and meticulously remove film residues, ensuring impeccable results.
In the realm of foundry sand regeneration, the rapid and efficient cooling of old sand alongside precise film residue removal are critical for maximizing sand mold reuse and achieving top-tier casting quality. Our equipment leverages cutting-edge continuous boiling cooling technology paired with an advanced spiral tube heat exchange system. This dual innovation ensures old sand is cooled to ≤40ºC, while achieving an impressive resin film removal rate of over 95%. In this comprehensive analysis, discover how our equipment revolutionizes sand cooling standards with its capability to continuously process 20-50t/h, all while maintaining an energy consumption of ≤1.8kW·h per ton of sand. Explore the technical principles, unique advantages, industrial applications, and the substantial economic benefits that make our machinery indispensable.
1. Technical principles and core design breakthroughs
With a focus on the cooling attributes of old sand, initially at temperatures between 80-120ºC and film contents of 3-8%, our equipment pioneers a technological leap forward by harnessing the dynamic heat exchange of the fluidized bed combined with a sophisticated multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
Experience the marvel of our high-pressure fan, generating wind pressures of 6-10kPa to induce a boiling state in the sand layer. This elevates the sand particles to a suspension height of 50-150mm and expands the heat exchange surface area to five times that of a static bed. In just 3-5 minutes, sand temperatures plummet from 120ºC to a refreshing 45ºC.
Our spiral cooling tubes, crafted from durable 316L stainless steel, are ingeniously arranged in a serpentine layout. The cooling water, maintained at an optimal 5-25ºC, flows counter to the sand, resulting in a remarkable heat exchange efficiency of 85%, outperforming traditional shell-and-tube structures by 30%.
Film efficient removal system:
The centrifugal stripping module is a testament to engineering excellence. Within the boiling state, sand particles ingeniously rub against the tube wall, achieving a resin film breakage rate exceeding 90%, with a minuscule residual film thickness of ≤0.02mm.
Marvel at the cyclone dust removal paired with water film adsorption. This dual purification system boasts a dust removal efficiency exceeding 99%, masterfully eliminating micro powder (≤75μm) and film debris. Ensuring an eco-friendly operation, our exhaust gas emission concentration is maintained at <10mg/m³.
Intelligent control module:
2. Core advantages and industry value
Revolutionizing traditional cooling methods, our equipment stands as a paragon of progression, delivering superior continuous operation capacity and brilliant energy efficiency:
Efficiency and quality advantages:
With a continuously adjustable processing capacity ranging from 20-50t/h, our equipment enhances cooling uniformity by 50% over its intermittent counterparts, achieving a sand temperature standard deviation of merely ≤2ºC.
Regenerated sand sees a dramatic reduction in loss on ignition (LOI) from 3.5% to below 1.2%. The tensile strength fluctuation of sand molds is impressively controlled to ≤0.2MPa. Our innovations ensure remarkable energy efficiency and eco-conscious operations.
The airtight design ensures compliance with the GB 16297-1996 standard, maintaining a dust concentration in the working environment of <1mg/m³, showcasing our commitment to a healthier workplace.
Maintenance and adaptability:
Our modular spiral tube group, featuring a quick-release design, is a triumph of convenience, allowing replacements in under 4 hours and reducing annual maintenance costs by an astounding 60%.
Engineered for versatility, our system can seamlessly integrate with vibrating screens and magnetic separators, forming a comprehensive 'cooling-purification-regeneration' production line. It’s compatible with various processes, including resin sand and water glass sand, offering unparalleled adaptability.
