Product Description
This series of cutting-edge equipment serves as a continuous sand cooler, expertly designed to effortlessly integrate loose old sand into the cooling bed. Here, under the influence of a high-pressure fan's vigorous blast, the sand achieves a fluidized boiling state. As the sand progresses, it winds around the strategically placed coil cooling pipes, advancing forward in a controlled path. This unique setup, with its robust suction and efficient cooling water systems, ensures the old sand is thoroughly cooled and its film is effectively removed.
In the realm of foundry sand regeneration, the swift and precise cooling of used sand, coupled with effective film residue removal, is paramount to enhancing both the reuse rate of sand molds and the overall quality of castings. This innovative equipment harnesses continuous boiling cooling technology paired with a spiral tube-enhanced heat exchange system, achieving a dual triumph: cooling old sand to impressive temperatures (≤40ºC) and achieving a resin film removal rate exceeding 95%. In this analysis, we delve deeply into how this equipment revolutionizes the standards of sand cooling processes, boasting a consistent processing capacity of 20-50t/h and maintaining energy consumption at a minimal ≤1.8kW·h per ton of sand. We will explore these advancements through lenses of technical principles, core advantages, industry applications, and economic benefits.
1. Technical principles and core design breakthroughs
Focusing on the cooling dynamics of old sand—characterized by an initial temperature range of 80-120ºC and a film content of 3-8%—this equipment introduces a groundbreaking technological advancement. It blends dynamic heat exchange via a fluidized bed with a sophisticated multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
A high-pressure fan, exerting wind pressure between 6-10kPa, ingeniously propels the sand layer into a boiling state. This results in a sand particle suspension height ranging from 50-150mm, significantly expanding the heat exchange area to five times that of a static bed. Remarkably, the sand's temperature can plummet from 120ºC to a cool 45ºC within just 3-5 minutes.
Serpentine spiral cooling tubes, crafted from premium 316L stainless steel, are expertly laid out to ensure maximum contact with sand flow in a reverse motion. The cooling water, maintained between 5-25ºC, facilitates a formidable heat exchange efficiency of 85%, outpacing traditional shell-and-tube structures by 30%.
Film efficient removal system:
The centrifugal stripping module advances sand particles to rub vigorously against the tube wall in a boiling state, achieving a resin film breakage rate surpassing 90%, with residual film thickness kept to a minimal ≤0.02mm.
Cyclone dust removal coupled with water film adsorption forms a powerful two-stage purification system, delivering a dust removal efficiency exceeding 99%. This system adeptly achieves the simultaneous extraction of micropowder (≤75μm) and film removal debris, maintaining exhaust gas emissions at an impressively low concentration of <10mg/m³.

2. Core advantages and industry value
Unlike conventional vibrating cooling beds, this advanced equipment offers multi-dimensional enhancements in continuous operation capacity and optimized energy consumption:
Efficiency and quality advantages:
The processing capacity, precisely adjustable between 20-50t/h, ensures continuous, high-performance operations. The cooling uniformity is enhanced by 50%, with a sand temperature standard deviation maintained at ≤2ºC, setting it far above intermittent equipment.
Loss on ignition (LOI) of regenerated sand is impressively reduced from 3.5% to below 1.2%. Additionally, the tensile strength fluctuation of sand molds is expertly controlled, remaining at ≤0.2MPa. Energy-saving and environmentally friendly features:
Engineered with a closed structure (leakage rate <3mg/m³), this equipment aligns with the GB 16297-1996 standard, ensuring that dust concentration within the working environment is kept under 1mg/m³.
Maintenance and adaptability:
The modular spiral tube group, featuring an innovative quick-release design, ensures swift component exchanges in under 4 hours, leading to average annual maintenance cost reductions by an impressive 60%.
This system's versatility allows it to seamlessly integrate vibrating screens and magnetic separators, creating a comprehensive 'cooling-purification-regeneration' production line, adeptly serving processes such as resin sand, water glass sand, and beyond.
