Product Description
This series of equipment is a continuous cooler, loose old sand into the cooling bed, in the case of high pressure fan strong blast, boiling state, and from the inlet began to wind around the coil cooling pipe meandering forward, in the strong suction and cooling water, the old sand can be fully cooled film removal.
In the foundry sand regeneration process, the rapid cooling of old sand and the removal of film residues directly affect the reuse rate of sand molds and the quality of castings. This series of equipment adopts continuous boiling cooling technology and spiral tube enhanced heat exchange system to achieve a double breakthrough in cooling old sand (≤40ºC) and resin film removal rate >95%. This article will deeply analyze how this equipment reshapes the sand cooling process standard with a continuous processing capacity of 20-50t/h and an energy consumption of ≤1.8kW·h per ton of sand from the perspectives of technical principles, core advantages, industry applications and economic benefits.
1. Technical principles and core design breakthroughs
Based on the cooling characteristics of old sand (initial temperature 80-120ºC, film content 3-8%), the equipment achieves technological innovation through dynamic heat exchange of the fluidized bed and multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
High-pressure fan (wind pressure 6-10kPa) drives the sand layer to form a boiling state, the sand particle suspension height is 50-150mm, the heat exchange area is 5 times higher than the static bed, and the sand temperature drops from 120ºC to 45ºC in only 3-5 minutes;
Spiral cooling tubes (material 316L stainless steel) are arranged in a serpentine shape, and the cooling water (5-25ºC) contacts the sand flow in reverse, with a heat exchange efficiency of 85%, which is 30% higher than the shell-and-tube structure.
Film efficient removal system:
Centrifugal stripping module: Sand particles rub against the tube wall in a boiling state, the resin film breakage rate is >90%, and the residual film thickness is ≤0.02mm;
Cyclone dust removal + water film adsorption: The two-stage purification system (dust removal efficiency >99%) realizes the simultaneous removal of micro powder (≤75μm) and film removal debris, and the exhaust gas emission concentration is <10mg/m³.
Intelligent control module:
2. Core advantages and industry value
Compared with the traditional vibrating cooling bed, this equipment achieves multi-dimensional upgrades through continuous operation capacity and energy consumption optimization:
Efficiency and quality advantages:
The processing capacity is 20-50t/h continuously adjustable, and the cooling uniformity (sand temperature standard deviation ≤2ºC) is 50% higher than that of intermittent equipment;
The loss on ignition (LOI) of regenerated sand is reduced from 3.5% to below 1.2%, and the tensile strength fluctuation of sand mold is ≤0.2MPa. Energy-saving and environmentally friendly features:
The closed structure (leakage rate <3mg/m³) complies with GB 16297-1996 standard, and the dust concentration in the working environment is <1mg/m³.
Maintenance and adaptability:
The modular spiral tube group (quick-release design) takes less than 4 hours to replace, and the average annual maintenance cost is reduced by 60%;
It can integrate vibrating screens and magnetic separators to form a "cooling-purification-regeneration" production line, which is suitable for resin sand, water glass sand and other processes
