Product Description
Introducing our state-of-the-art Sand Cooler Multi-Cooler, a technological marvel designed for the efficient cooling of old green sand. This dynamic machine ensures a harmonious blend of temperature, humidity, and composition throughout the sand, thanks to its compact design and stable operation. Experience low energy consumption paired with a stellar cooling effect, as the high-pressure fan effortlessly maintains the sand in a boiling state, achieving optimal cooling results. With an adjustable unloading door, control the material flow with precision. Seamlessly integrating an automatic temperature and humidification system along with a blower, induced fan, and water system, this unit represents the pinnacle of sand cooling technology.
Flexibility is at the heart of our machine’s design. Depending on your installation needs, choose between straight line or vertical discharging configurations. When placing your order, rest assured that both left and right unloading directions are available, tailored to enhance operational efficiency.
In the intricate process of old sand regeneration within foundry workshops, the uniformity and efficiency of cooling high-temperature wet sand (ranging from 80-150ºC with a water content of 3-8%) play a crucial role in determining the reuse rate of molding sand and the quality of the final castings. The innovative double-disc stirring cooler offers a revolutionary, energy-saving solution, customizable to your needs, by utilizing a boiling heat exchange system and precise multi-parameter control technology. This detailed analysis will delve into how our equipment is redefining energy efficiency standards in sand processing by exploring thermodynamic principles, process adaptability, intelligent control systems, and multi-industry applications.
1. Technical principle and core component design
Our equipment achieves groundbreaking technological advancements for cooling old sand particles (particle size range 0.15-1.2mm) through two pioneering technologies: fluidized cooling and dynamic homogenization.
Boiling state heat exchange system:
Utilizing a high-pressure centrifugal fan with an air volume of 8000-25000m³/h, this system elevates the sand layer into a suspended, boiling state (with a height of 300-600mm). This expansion of the contact area between sand particles and cool air increases cooling efficiency to 30-80t/h and delivers a 40% energy saving compared to traditional vibrating cooling beds.
Stepped air distribution plate: A porous ceramic hood with 35% porosity works in harmony with guide vanes, ensuring uniform airflow distribution (with speed deviation <5%) to prevent localized overheating or agglomeration.
Coordinated control of temperature and humidity:
Dual-fluid nozzle system: By meticulously controlling the blend of compressed air (0.6MPa) and atomized water (with particle sizes of 10-50μm), maintain the old sand's humidity at 2.5±0.3% while reducing its temperature to a safe and effective ≤35ºC.
Infrared thermal imager: Monitor the sand layer's temperature field in real-time (with an accuracy of ±1ºC) and dynamically adjust fan speed and water spray volume to eliminate any cooling dead corners.
Modular structural design:
Linear/vertical dual mode:
Linear type (L series): Specifically designed for sand processing lines with ample ground space, boasting a maximum processing capacity of 100t/h.
Vertical type (V series): Featuring a tower layout (requiring ≤8m of space), this model is ideal for compact production lines in workshops with a height exceeding 8m.
Two-way unloading door: Customize the unloading process with an adjustable pneumatic gate valve (ranging from 0-100%), offering an unloading accuracy of ±2% and a choice between left or right discharge directions.
2. Full-process integrated solution for foundry sand treatment
Our advanced equipment seamlessly integrates into the sand-sanding-screening-cooling-regeneration process chain, crafting an intelligent and comprehensive cooling unit.
Pretreatment of high-temperature old sand:
By linking with the vibrating conveyor, it effectively initiates the cooling of 600ºC red sand (bringing it down to 150-200ºC) to prevent high-temperature deformation of the fluidized bed.
Harnessing precision engineering at its finest, our magnetic separation module, boasting an impressive magnetic induction intensity of ≥1200Gs, meticulously eliminates iron bean impurities. This not only ensures the utmost purity but also offers robust protection to the air distribution plate, safeguarding it from impact wear and extending its longevity.
Revolutionary Closed-Loop Water Circulation System:
Experience unparalleled sustainability with our closed-loop water system that ingeniously recycles wastewater. By employing a state-of-the-art cyclone separator, achieving a removal rate exceeding 95%, and a highly efficient plate heat exchanger, maintaining a precise temperature difference of ≤5ºC, we realize a remarkable water saving rate of 70%—a testament to our commitment to resource conservation.
Cutting-Edge Intelligent Dust Removal System:
At the pinnacle of innovation, our design seamlessly integrates a pulse bag dust collector at the top, achieving an astounding filtration efficiency of 99.9%. The emission concentration is meticulously controlled to be less than <10mg/m³, while the noise levels in the working area are maintained at a comfortable ≤75dB(A), ensuring a serene workspace.
3. Unparalleled Core Advantages and Tangible Economic Benefits
In stark contrast to conventional cooling equipment, our breakthrough machine harnesses the power of energy recovery and cutting-edge digital twin control, catapulting efficiency to unprecedented heights:
Pioneering Energy Consumption Optimization:
Our advanced heat pipe waste heat recovery device ingeniously transforms exhaust gas heat, ranging from 80-120ºC, into usable hot water (50-70ºC), ingeniously slashing steam costs by over 800,000 yuan annually. This remarkable saving is calculated based on a substantial processing capacity of 50t/h.
Combining the prowess of a variable frequency fan with a permanent magnet motor, our system achieves a remarkable power consumption reduction, with energy usage per ton of sand as low as ≤1.2kW·h—an impressive 35% lower than comparable equipment, setting a new standard for efficiency.
Exemplary Quality Improvement Data:
The precision of our technology shines through in the reduced fluctuation of the compaction rate of the molding sand, now minimized from ±2.5% to an impressive ±0.8%. Moreover, the porosity defect rate of castings has been slashed by an extraordinary 75%, ensuring top-tier product quality.
A monumental leap in resource efficiency, our system elevates the reuse rate of old sand to an impressive 90%, effectively slashing the cost of replenishing new sand by a significant 50%, making operations not only cost-effective but also environmentally conscious.
Effortless Maintenance Convenience:
Ingeniously designed for rapid maintenance, our quick-detachable hood allows for the swift replacement of a single hood in less than 3 minutes, minimizing downtime and maximizing productivity.
Our observation window and maintenance platform are meticulously crafted to meet OSHA standards, providing robust support for seamless online maintenance, ensuring safety and operational efficiency at all times.
