Product Description
Presenting a pioneering series of continuous coolers engineered for optimum efficiency: the Custom Fluidized Bed Sand Cooler with Comprehensive After-Sales Assistance. This remarkable equipment seamlessly integrates a robust high-pressure fan to initiate a vigorous boiling state, effectively loosening old sand as it enters the cooling bed. It ingeniously employs a coil cooling pipe system, ensuring uniform wind distribution from the inlet, and propelling the sand forward in a swirling motion. This dynamic action, combined with the potent suction and cooling water mechanisms, guarantees thorough cooling and impeccable film removal, setting an industry benchmark.
In the intricate world of foundry sand regeneration, achieving rapid cooling of old sand while efficiently removing film residues is paramount. This process directly influences the reuse rate of sand molds and the quality of castings. Our state-of-the-art equipment revolutionizes the sand cooling process with its cutting-edge continuous boiling cooling technology and an advanced spiral tube heat exchange system. These innovations not only achieve an exceptional cooling rate (≤40ºC) but also boast a resin film removal rate exceeding 95%. This comprehensive analysis delves into the technical principles, core advantages, industry applications, and economic benefits, showcasing how this system elevates the sand cooling standards with its impressive processing capacity of 20-50t/h and remarkably low energy consumption of ≤1.8kW·h per ton of sand.
1. Technical principles and core design breakthroughs
Addressing the cooling intricacies of old sand (initial temperature range: 80-120ºC; film content: 3-8%), this equipment pioneers technological advancements through its dynamic heat exchange capabilities within a fluidized bed, complemented by a multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
Harnessing the power of a high-pressure fan (wind pressure: 6-10kPa), the sand layer is transformed into a boiling state, lifting sand particles to a suspension height of 50-150mm. This process dramatically expands the heat exchange area to five times that of a static bed, efficiently reducing sand temperature from 120ºC to 45ºC within a mere 3-5 minutes.
Spiral cooling tubes, crafted from premium 316L stainless steel, are strategically arranged in a serpentine pattern. The cooling water (temperature range: 5-25ºC) flows counter to the sand, achieving an impressive heat exchange efficiency of 85%, surpassing traditional shell-and-tube structures by 30%.
Film efficient removal system:
The centrifugal stripping module enhances the process as sand particles interact with the tube wall in the boiling state, resulting in a resin film breakage rate exceeding 90% and a minimal residual film thickness of ≤0.02mm for superior quality.
A sophisticated cyclone dust removal in conjunction with a water film adsorption system forms a two-stage purification process, achieving a dust removal efficiency of over 99%. This system adeptly manages the simultaneous extraction of micro powder (≤75μm) and film debris, ensuring exhaust gas emission concentrations remain below 10mg/m³.

2. Core advantages and industry value
In stark contrast to traditional vibrating cooling beds, this cutting-edge equipment offers multidimensional enhancements, featuring continuous operation capabilities and optimized energy consumption:
Efficiency and quality advantages:
With a seamlessly adjustable processing capacity of 20-50t/h, this equipment delivers unmatched cooling uniformity (sand temperature standard deviation ≤2ºC), surpassing intermittent equipment by 50%.
The loss on ignition (LOI) of regenerated sand is significantly reduced from 3.5% to below 1.2%, while maintaining a tensile strength fluctuation of sand mold within ≤0.2MPa. Its energy-efficient and environmentally friendly design ensures compliance with strict standards.
Designed with a closed structure, minimizing leakage rates to <3mg/m³, it adheres to GB 16297-1996 standards, ensuring dust concentrations in the working environment are maintained at <1mg/m³.
Maintenance and adaptability:
Engineered for convenience, the modular spiral tube group features a quick-release design, allowing replacements in under 4 hours and reducing average annual maintenance costs by 60%.
Versatile in its application, the system can integrate vibrating screens and magnetic separators to create a comprehensive 'cooling-purification-regeneration' production line, suitable for diverse processes such as resin sand and water glass sand.
