Product Description
This series of equipment represents a revolution in cooling technology, designed as a continuous cooler that seamlessly integrates into your production line. By introducing loose old sand into the cooling bed, it utilizes a high-pressure fan to create a dynamic boiling state. As the sand meanders forward through the cooling pipes, the strong suction paired with cooling water ensures that the old sand is meticulously cooled while removing film residues.
In the crucial process of foundry sand regeneration, the ability to rapidly cool old sand and effectively remove film residues is paramount. The efficiency of this process directly influences the reuse rate of sand molds and, consequently, the quality of castings produced. This advanced equipment employs continuous boiling cooling technology alongside a spiral tube enhanced heat exchange system, setting new standards in the industry. With its impressive performance, the equipment delivers a cooling efficiency for old sand to ≤40ºC and achieves a resin film removal rate of over 95%. In this detailed analysis, we examine how this equipment revolutionizes sand cooling by offering a continuous processing capacity of 20-50t/h, while maintaining an energy consumption of ≤1.8kW·h per ton of sand. We will delve into its technical principles, core advantages, industry applications, and economic benefits.
1. Technical principles and core design breakthroughs
Building on the specific cooling characteristics of old sand (initial temperatures ranging from 80-120ºC, with film content between 3-8%), this equipment introduces a groundbreaking approach with its dynamic heat exchange fluidized bed and multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
Utilizing a high-pressure fan with a wind pressure of 6-10kPa, the system elevates the sand layer into a boiling state, allowing the sand particles to achieve a suspension height of 50-150mm. This results in a heat exchange area that is five times greater than a static bed, enabling the sand temperature to plummet from 120ºC to 45ºC in merely 3-5 minutes.
Spiral cooling tubes, crafted from 316L stainless steel, are meticulously arranged in a serpentine configuration. Cooling water ranging from 5-25ºC flows in reverse contact with the moving sand, achieving a remarkable heat exchange efficiency of 85%, a full 30% improvement over traditional shell-and-tube structures.
Film efficient removal system:
The centrifugal stripping module ensures that sand particles, while in a boiling state, effectively rub against the tube walls, leading to a resin film breakage rate exceeding 90% and achieving a minimal residual film thickness of ≤0.02mm.
With a dual-stage purification system, the combination of cyclone dust removal and water film adsorption achieves unparalleled efficiency (dust removal efficiency >99%), proficiently eliminating micro powder debris (≤75μm) and film residues, while maintaining exhaust gas emissions at a concentration of <10mg/m³.

2. Core advantages and industry value
This equipment distinguishes itself from traditional vibrating cooling beds by delivering comprehensive upgrades in continuous operation and energy efficiency, offering unparalleled advancements:
Efficiency and quality advantages:
Boasting a continuously adjustable processing capacity of 20-50t/h, the equipment enhances cooling uniformity by 50% compared to intermittent systems, with a sand temperature standard deviation of only ≤2ºC.
The loss on ignition (LOI) for regenerated sand is significantly reduced from 3.5% to under 1.2%, with exceptional tensile strength stability in sand molds (fluctuation ≤0.2MPa). Energy-saving and environmentally friendly features:
Designed with a closed structure, leakage rates are kept to <3mg/m³, adhering to the GB 16297-1996 standard, while maintaining dust concentrations in the working environment at a nominal <1mg/m³.
Maintenance and adaptability:
The modular spiral tube group features a quick-release design, allowing replacements in under 4 hours and reducing average annual maintenance costs by an impressive 60%.
Capable of integrating vibrating screens and magnetic separators, it forms a complete 'cooling-purification-regeneration' production line, adeptly handling resin sand, water glass sand, and other processes.
