Product Description
This innovative series of equipment is crafted as a continuous cooler designed to handle loose old sand with unparalleled efficiency. By integrating a high-pressure fan system for powerful airflow, this equipment transforms the sand into a boiling state, beginning its journey across a sophisticated coil cooling pipe. As the sand meanders forward, in concert with potent suction and cooling water, it achieves full cooling and film removal, delivering remarkable performance.
In the realm of foundry sand regeneration, the swift cooling of old sand and the efficient removal of film residues are critical factors influencing the sand molds' reuse rate and the castings' quality. This series employs cutting-edge continuous boiling cooling technology coupled with a spiral tube enhanced heat exchange system, marking a significant leap in cooling capabilities for old sand (≤40ºC) and ensuring a resin film removal rate exceeding 95%. This comprehensive analysis delves into how this equipment redefines the sand cooling process standards, boasting continuous processing of 20-50t/h and minimal energy use of ≤1.8kW·h per ton. We explore its technical principles, core advantages, diverse industry applications, and compelling economic benefits.
1. Technical principles and core design breakthroughs
Considering the cooling characteristics of old sand (initial temperature ranging from 80-120ºC with a film content of 3-8%), this equipment introduces a technological marvel through the fluidized bed's dynamic heat exchange and a synergistic multi-stage wind-water system:
Continuous fluidized cooling technology:
The high-pressure fan (wind pressure 6-10kPa) propels the sand layer into a dynamic boiling state, elevating sand particles to a suspension height of 50-150mm. This creates an expansive heat exchange area, five times greater than static beds, rapidly reducing sand temperature from 120ºC to 45ºC within just 3-5 minutes;
Ingeniously arranged in a serpentine shape, the spiral cooling tubes made of 316L stainless steel allow cooling water (5-25ºC) to counterflow the sand, achieving remarkable heat exchange efficiency of 85%, surpassing the shell-and-tube structure by 30%.
Film efficient removal system:
The centrifugal stripping module ensures that sand particles, in their boiling state, effectively rub against the tube walls, achieving a resin film breakage rate of over 90%, with residual film thickness maintained at ≤0.02mm;
The combination of cyclone dust removal and water film adsorption creates a two-stage purification system that boasts an impressive dust removal efficiency >99%. This system simultaneously eliminates micropowder (≤75μm) and film removal debris, ensuring that exhaust gas emission concentration remains below 10mg/m³.

2. Core advantages and industry value
This equipment redefines standards by surpassing traditional vibrating cooling beds with multidimensional upgrades that enhance continuous operation capabilities and optimize energy consumption:
Efficiency and quality advantages:
Its processing capacity is continuously adjustable between 20-50t/h, achieving cooling uniformity with a sand temperature standard deviation ≤2ºC, a 50% improvement over intermittent models;
The loss on ignition (LOI) for regenerated sand is drastically reduced from 3.5% to below 1.2%, while sand mold tensile strength variability remains ≤0.2MPa. Energy-saving and environmentally friendly features:
The equipment's closed structure, with a leakage rate <3mg/m³, fully complies with GB 16297-1996 standards, maintaining dust concentrations in the working environment below 1mg/m³.
Maintenance and adaptability:
Its modular spiral tube group, featuring a quick-release design, allows replacements in under 4 hours, slashing average annual maintenance costs by 60%;
Furthermore, it seamlessly integrates vibrating screens and magnetic separators to establish a comprehensive "cooling-purification-regeneration" production line, tailored for resin sand, water glass sand, and myriad other processes.
