Product Description
Introducing a revolutionary series of equipment: the High-Performance Fluidized Bed Sand Cooler! This cutting-edge continuous cooler seamlessly integrates advanced technology to rejuvenate and cool old sand. As loose sand enters the cooling bed, it encounters a powerful high-pressure fan blast, initiating a dynamic boiling state. From here, the sand begins its journey, winding around a serpentine cooling coil. Thanks to the robust cooling water system and potent suction mechanisms, aged sand is thoroughly cooled and stripped of film residues, setting a new standard in sand processing.
In the realm of foundry sand regeneration, the rapid and efficient cooling of old sand, along with effective film residue removal, is pivotal. These factors significantly influence the reuse potential of sand molds and the resultant quality of castings. Our state-of-the-art equipment leverages continuous boiling cooling technology paired with an innovative spiral tube-enhanced heat exchange system. This dual approach achieves remarkable cooling efficiencies, bringing old sand temperatures down to a remarkable ≤40ºC and achieving a resin film removal rate exceeding 95%. This comprehensive analysis will delve into how this equipment is redefining standards, featuring a continuous processing capacity of 20-50t/h and an impressive energy consumption benchmark of ≤1.8kW·h per ton of sand. Explore the technical foundations, inherent advantages, industrial applications, and economic rewards embedded in this groundbreaking solution.
1. Technical principles and core design breakthroughs
Tailored to meet the cooling demands of old sand, with initial temperatures ranging between 80-120ºC and a film content of 3-8%, our equipment pioneers technological advancements. It utilizes dynamic heat exchange facilitated by a fluidized bed and a sophisticated multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
Harnessing the power of a high-pressure fan, generating wind pressures of 6-10kPa, the sand layers are elevated into a boiling state. This results in sand particles being suspended at a height of 50-150mm, amplifying the heat exchange area by fivefold compared to static beds. Consequently, sand temperatures plummet from 120ºC to a remarkable 45ºC in just 3-5 minutes;
Meticulously designed spiral cooling tubes, crafted from 316L stainless steel, are arranged in a serpentine configuration. The cooling water, maintained between 5-25ºC, flows in reverse harmony with the sand stream, achieving a heat exchange efficiency of 85%, surpassing traditional shell-and-tube structures by 30%.
Film efficient removal system:
The innovative centrifugal stripping module ensures that sand particles dynamically interact with the tube wall in a boiling state, resulting in a resin film breakage rate exceeding 90%, with residual film thickness contained to ≤0.02mm;
The dual-stage purification system, featuring Cyclone dust removal alongside water film adsorption, boasts a dust removal efficiency of over 99%. This ensures the concurrent elimination of micro powder (≤75μm) and film debris, maintaining exhaust gas emission concentrations under 10mg/m³.

2. Core advantages and industry value
Revolutionizing traditional cooling beds, this equipment shines with multi-dimensional advancements, offering an unparalleled combination of continuous operation capacity and energy-efficient optimization:
Efficiency and quality advantages:
Boasting a processing capacity that is continuously adjustable between 20-50t/h, the equipment delivers cooling uniformity with a sand temperature standard deviation of ≤2ºC, a 50% improvement over intermittent systems;
The loss on ignition (LOI) of regenerated sand is impressively reduced from 3.5% to below 1.2%, while the tensile strength fluctuation of sand molds is minimized to ≤0.2MPa. This equipment is a beacon of energy-saving and environmentally friendly innovation:
Featuring a closed structure with a leakage rate of <3mg/m³, the equipment is compliant with the GB 16297-1996 standard. It ensures that dust concentrations within the working environment remain below 1mg/m³, promoting a clean and safe workspace.
Maintenance and adaptability:
The modular spiral tube group, designed for quick release, facilitates rapid replacement in under 4 hours, and reduces average annual maintenance costs by an astounding 60%;
Capable of integrating vibrating screens and magnetic separators, this equipment forms a comprehensive "cooling-purification-regeneration" production line, making it ideally suited for processes involving resin sand, water glass sand, and more.
