Product Description
Introducing our revolutionary Factory Custom Boiling Cooling Bed, a masterpiece in sand cooling technology. This state-of-the-art equipment is engineered to seamlessly integrate loose, reclaimed sand into the cooling bed, where it is transformed by the potent force of a high-pressure fan. This transformation brings sand into an energetic, fluidized boiling state. Progressing through the system, the sand navigates around meticulously arranged coil cooling pipes, moving forward with precision. This ingenious configuration, bolstered by powerful suction and an advanced cooling water system, guarantees that the sand is thoroughly cooled, with its film meticulously stripped away.
In the world of foundry sand regeneration, the rapid cooling and effective film removal from used sand are essential for maximizing mold reuse rates and casting quality. Our groundbreaking equipment combines continuous boiling technology with a spiral tube-enhanced heat exchange system to achieve remarkable results: cooling sand to temperatures of ≤40ºC and achieving over 95% resin film removal efficiency. This comprehensive analysis delves into how our equipment is setting new standards, with a consistent processing capacity of 20-50t/h while keeping energy consumption efficiently minimized at ≤1.8kW·h per ton of sand. We will explore these innovations through the perspectives of technical principles, core advantages, industry applications, and economic benefits, showcasing a new era in sand cooling.
1. Technical principles and core design breakthroughs
Our equipment revolutionizes the cooling of old sand, initially at temperatures of 80-120ºC with a film content of 3-8%, by introducing a significant technological leap. It synergizes dynamic heat exchange within a fluidized bed alongside a sophisticated multi-stage wind-water system:
Continuous fluidized cooling technology:
A high-pressure fan, delivering wind pressure between 6-10kPa, elevates the sand layer into a dynamic boiling state. This process suspends sand particles at heights of 50-150mm, amplifying the heat exchange area to an unprecedented five times that of static beds. Remarkably, within just 3-5 minutes, sand temperatures plummet from 120ºC to a refreshing 45ºC.
Serpentine spiral cooling tubes, crafted with precision from premium 316L stainless steel, are strategically positioned to ensure optimal contact with the sand flow in a reverse motion. Maintaining cooling water temperatures between 5-25ºC, these tubes achieve an exceptional heat exchange efficiency of 85%, outperforming traditional shell-and-tube structures by a striking 30%.
Film efficient removal system:
Our centrifugal stripping module propels sand particles to vigorously interact with the tube wall in a boiling state, achieving an impressive resin film breakage rate of over 90%, with residual film thickness minimized to ≤0.02mm.
The combination of cyclone dust removal and water film adsorption creates a formidable two-stage purification system, achieving dust removal efficiency exceeding 99%. This system skillfully extracts micropowder (≤75μm) and film removal debris, maintaining exhaust gas emissions at an outstandingly low concentration of <10mg/m³.

2. Core advantages and industry value
Distinguished from traditional vibrating cooling beds, our advanced equipment offers unparalleled improvements in continuous operation capacity and optimized energy consumption:
Efficiency and quality advantages:
The equipment's processing capacity is finely adjustable between 20-50t/h, ensuring uninterrupted, high-performance operations. Cooling uniformity is enhanced by 50%, with a sand temperature standard deviation maintained at ≤2ºC, positioning it well above conventional intermittent equipment.
The Loss on Ignition (LOI) of regenerated sand is impressively reduced from 3.5% to below 1.2%. Moreover, the tensile strength fluctuation of sand molds is expertly controlled to remain at ≤0.2MPa, showcasing its energy-saving and eco-friendly features that set it apart.
Crafted with precision, our state-of-the-art equipment boasts a sophisticated closed structure, achieving an impressive leakage rate of less than 3mg/m³. This meticulously designed feature ensures strict compliance with the esteemed GB 16297-1996 standard. As a result, the dust concentration within your working environment is maintained at an extraordinary low of under 1mg/m³, promoting a healthier and more efficient workspace.
Maintenance and adaptability redefined:
Our cutting-edge modular spiral tube group is engineered with an innovative quick-release design, facilitating rapid component exchanges in a remarkable time frame of under 4 hours. This groundbreaking feature leads to substantial savings, reducing average annual maintenance costs by an astounding 60%, ensuring both operational efficiency and cost-effectiveness for your business.
Experience unparalleled versatility with our system, which effortlessly integrates vibrating screens and magnetic separators. This dynamic configuration establishes a fully integrated 'cooling-purification-regeneration' production line that adeptly caters to a wide array of processes, including resin sand, water glass sand, and more. Elevate your production capabilities with this comprehensive solution.
