Product Description
Introducing our state-of-the-art series of sand cooling equipment: a revolutionary continuous sand cooler designed to seamlessly incorporate loose old sand into its advanced cooling bed. Experience the magic of our powerful high-pressure fan, which transforms sand into a fluidized boiling state, enabling it to spiral elegantly around strategically positioned coil cooling pipes. This sophisticated configuration, with its robust suction mechanism and highly efficient cooling water systems, ensures that the old sand is not only thoroughly cooled but also impeccably cleaned.
In the dynamic field of foundry sand regeneration, achieving the rapid and precise cooling of used sand while effectively removing film residues is crucial to enhancing the reuse rate of sand molds and elevating the quality of castings. Our pioneering equipment employs continuous boiling cooling technology combined with a spiral tube-enhanced heat exchange system, achieving dual victories: cooling old sand to a remarkable ≤40ºC and achieving an exceptional resin film removal rate exceeding 95%. This comprehensive analysis explores how our equipment sets new benchmarks in sand cooling processes, offering a consistent processing capacity of 20-50t/h while maintaining minimal energy consumption of ≤1.8kW·h per ton of sand. Join us as we explore these groundbreaking advancements through technical insights, core benefits, industry applications, and economic impacts.
1. Technical principles and core design breakthroughs
Our equipment addresses the cooling dynamics of old sand—typically starting at 80-120ºC with a film content of 3-8%—by introducing a groundbreaking technological innovation. It combines dynamic heat exchange through a fluidized bed with an advanced multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
Harnessing the impressive power of a high-pressure fan, exerting wind pressures between 6-10kPa, the sand layer is ingeniously propelled into a boiling state. This phenomenon elevates sand particle suspension heights between 50-150mm, significantly amplifying the heat exchange surface area to fivefold that of a static bed. Astonishingly, sand temperatures can plummet from 120ºC to a refreshing 45ºC within just 3-5 minutes.
Crafted from premium 316L stainless steel, the serpentine spiral cooling tubes are expertly arranged to maximize contact with the sand flow in a reverse motion. The cooling water, maintained at an optimal 5-25ºC, achieves an outstanding heat exchange efficiency of 85%, outperforming traditional shell-and-tube structures by an impressive 30%.
Film efficient removal system:
Our centrifugal stripping module encourages sand particles to engage in vigorous rubbing against the tube wall while in a boiling state, achieving a resin film breakage rate exceeding 90%, with residual film thickness minimized to a scant ≤0.02mm.
The integration of cyclone dust removal with water film adsorption forms a formidable two-stage purification system, boasting a dust removal efficiency surpassing 99%. This system effectively extracts both micropowder (≤75μm) and film removal debris, maintaining exhaust gas emissions at an impressively low concentration of <10mg/m³.
Intelligent control module:
2. Core advantages and industry value
Our advanced equipment surpasses conventional vibrating cooling beds, offering multidimensional enhancements in continuous operation capacity and optimized energy consumption:
Efficiency and quality advantages:
With a precisely adjustable processing capacity of 20-50t/h, our equipment ensures continuous, high-performance operations. The uniformity of cooling is improved by 50%, achieving a sand temperature standard deviation of ≤2ºC, setting a new standard above intermittent equipment.
The Loss on Ignition (LOI) of regenerated sand is impressively reduced from 3.5% to below 1.2%. Furthermore, the tensile strength fluctuation of sand molds is expertly controlled, remaining at ≤0.2MPa. Featuring energy-saving and environmentally conscious design elements, our equipment aligns with modern sustainability goals.
Meticulously engineered with a robust closed structure boasting a leakage rate of less than 3mg/m³, this sophisticated equipment adheres impeccably to the stringent GB 16297-1996 standard. It guarantees that dust concentration within your working environment remains exceptionally low, under 1mg/m³, ensuring both safety and compliance.
Maintenance and Adaptability:
Our revolutionary modular spiral tube group is equipped with an innovative quick-release design, allowing for remarkably swift component exchanges in less than 4 hours. This cutting-edge feature significantly slashes average annual maintenance costs by a staggering 60%, revolutionizing efficiency.
The system's remarkable versatility enables it to seamlessly incorporate vibrating screens and magnetic separators. This integration forms a comprehensive 'cooling-purification-regeneration' production line, masterfully supporting processes for materials like resin sand and water glass sand, among various others.
