Product Description
Introducing our innovative series of Fluidized Bed Sand Coolers, meticulously engineered for continuous efficiency. This remarkable equipment seamlessly processes old sand, transforming it within the cooling bed. Utilizing a high-pressure fan, we create a dynamic boiling state, ensuring the sand winds through the cooling coil with precision and robustness. This advanced system guarantees thorough cooling and film removal, maximizing your production efficiency.
In the quest for excellence within the foundry industry, the rapid cooling of old sand and effective film residue removal are pivotal for enhancing the reuse rate of sand molds and elevating the quality of castings. Our avant-garde equipment employs a continuous boiling cooling technology paired with a spiral tube heat exchange system, achieving unparalleled results with old sand cooling (≤40ºC) and a resin film removal rate exceeding 95%. Join us as we delve into how this groundbreaking equipment is redefining sand cooling standards with a prodigious processing capacity of 20-50t/h and an impressively low energy consumption of ≤1.8kW·h per ton of sand. Discover the technical principles, core advantages, diverse industry applications, and economic benefits that make this equipment a true game-changer.
1. Technical principles and core design breakthroughs
Harnessing the unique cooling characteristics of old sand (initial temperature of 80-120ºC, film content of 3-8%), this equipment epitomizes technological revolution with its dynamic heat exchange mechanism via the fluidized bed and a sophisticated multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
A high-pressure fan, operating at a wind pressure of 6-10kPa, propels the sand layer into a vibrant boiling state, elevating the sand particle suspension height to 50-150mm. This enhancement amplifies the heat exchange area manifold, surpassing static beds by five times. Witness the sand temperature plummet from 120ºC to a cool 45ºC within a mere 3-5 minutes;
Ingeniously designed spiral cooling tubes, crafted from 316L stainless steel, trace a serpentine path, where cooling water (5-25ºC) engages the sand flow in reverse. This interaction boasts a remarkable heat exchange efficiency of 85%, outshining traditional shell-and-tube structures by 30%.
Film efficient removal system:
Our centrifugal stripping module ensures that sand particles energetically interact with the tube wall in a boiling state, achieving a resin film breakage rate >90% with a residual film thickness ≤0.02mm;
The cyclone dust removal coupled with water film adsorption form a two-stage purification system, achieving a dust removal efficiency >99%, simultaneously eliminating micro powder (≤75μm) and film debris, ensuring exhaust gas emissions remain <10mg/m³.
Intelligent control module:
2. Core advantages and industry value
Revolutionizing traditional methods, this equipment transcends the conventional vibrating cooling bed, presenting multi-dimensional enhancements through its continuous operation prowess and optimized energy consumption:
Efficiency and quality advantages:
Boasting an adjustable processing capacity of 20-50t/h, this system excels with a cooling uniformity (sand temperature standard deviation ≤2ºC) that is 50% superior to intermittent equipment;
The regenerated sand's loss on ignition (LOI) is impressively reduced from 3.5% to below 1.2%, while the tensile strength fluctuation of sand molds is maintained at ≤0.2MPa. Energy-saving and environmentally conscious features:
Our closed structure (leakage rate <3mg/m³) adheres to the rigorous GB 16297-1996 standard, ensuring a dust-free working environment with concentrations <1mg/m³.
Maintenance and adaptability:
The modular spiral tube group, designed for quick-release, can be replaced in under 4 hours, slashing average annual maintenance costs by 60%;
Seamlessly integrate with vibrating screens and magnetic separators to establish a comprehensive "cooling-purification-regeneration" production line, catering to resin sand, water glass sand, and other processes with unparalleled versatility.
