Product Description
Introducing the cutting-edge S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a true marvel in the realm of sand grain rejuvenation and restoration. This groundbreaking machine employs a robust dual-axis mechanism that expertly eradicates the resin curing agent lingering on the surface of sand grains. It achieves this through dynamic rubbing and advanced de-filming processes, ensuring each grain is renewed to perfection.
Elevating its operational efficiency to exceptional heights, the machine's base is ingeniously equipped with a high-performance fan that meticulously separates lingering old film and dust, ensuring pristine cleanliness. Following this meticulous treatment, the revitalized old sand exhibits an impressive level of integrity and beautifully rounded grains. This enhanced quality significantly reduces the need for additional liquid materials during subsequent mixing processes, promising a more cost-effective and streamlined production. Experience the pinnacle of sand recycling innovation with the S53 Scrubber Recycling Machine.
Serving as the cornerstone equipment for the regeneration of foundry old sand, the powerful rubbing regeneration machine enables the efficient stripping and renewal of old sands such as resin sand and water glass sand. This is achieved through the synergistic effect of dual-axis mechanical rubbing combined with airflow assistance. Below is a comprehensive analysis from the perspectives of technical principles, structural design, process flow, and practical application effects:
1. Technical principles and core mechanisms
The dual-axis regeneration machine leverages two sets of transmission main shafts rotating in opposing directions at high speed, with speeds reaching an impressive 720-970r/min. Equipped with wear-resistant alloy blades or cast iron rubbing discs on the shaft, this machine ensures superior performance. As sand enters the regeneration chamber, it is subjected to repeated rubbing and collision due to the linear shear force and convection of the blades. This mechanical action not only strips off the resin film and curing agent from the sand's surface but also achieves surface rounding through friction between sand particles, minimizing edge damage. Compared to the traditional three-axis structure, the dual-axis design optimizes chamber space, increases material throughput by 10-30t/h, and concurrently reduces energy consumption.
2. Boiling airflow assists film stripping. The bottom blower, with an air volume surpassing 3700m³/h, injects adjustable airflow into the chamber via the boiling orifice plate. This creates a fluidized environment of sand and air mixing. On one hand, this airflow enhances the collision frequency between sand particles, while on the other, the detached inert film and dust are expelled through the dust removal vent. This 'mechanical + airflow' dual effect elevates the film stripping rate to over 80%, and sand temperature can be reduced by 30-50ºC, showing remarkable efficiency.
3. Wear-resistant and vibration-reducing design. The rubbing blade employs the carbide convex rib welding process, significantly enhancing wear resistance by more than threefold. The chamber body and frame are interconnected with rubber elasticity, effectively suppressing vibration caused by high-speed operation and ensuring the equipment's stability and longevity.
4. Applicable sand mold and regeneration effect
Furan resin sand: Within a mere 180 seconds of rubbing, the brittle resin film is effectively removed, with burning loss maintained below 1.0%. The tensile strength of the regenerated sand is restored to an impressive 90% of new sand, demonstrating superior performance.
Water glass sand: When combined with wet regeneration (sand-water ratio 1:1.5) or a low-temperature freezing centrifugal process at -40ºC, the results are outstanding. However, employing dry regeneration as a pretreatment significantly reduces the subsequent wet load, offering a more efficient process.
Alkali phenolic resin sand: Demanding higher rubbing strength, such as wheel rolling pressurization, the tough film is effectively managed. Post-regeneration, the roundness of sand particles is enhanced, and gas emission is reduced by 30%, contributing to a cleaner production environment.
5. Technical advantages and economy
The regeneration efficiency is remarkably improved. Compared to the traditional centrifugal regeneration machine (power 22kW/stage) or airflow impact equipment, the unit energy consumption of the dual-axis regeneration machine is reduced by 40%. Furthermore, the sand particle crushing rate is maintained within 5%, with integrity surpassing that of vibration regeneration, highlighting the machine's superior technology and economic advantage.
Unlock the potential of your production cost savings with our innovative solution! The resin active film residue of the regenerated sand is impressively maintained at less than 0.3%. This feature allows for a remarkable reduction in the amount of curing agent needed, slashing it by 30%-50% during sand mixing. Furthermore, the optimized sand-iron ratio has evolved from the conventional 1:1 to a more efficient 1:1.5, substantially cutting down the expense of acquiring new sand and bolstering your bottom line.
Embrace the future of eco-friendly foundry operations with our solution designed for unparalleled environmental compatibility. Our dry regeneration technique operates without the generation of wastewater. Plus, our sophisticated pulse back-blowing dust removal system ensures that dust is centrally processed with a superior efficiency of over 99%. This stellar performance not only aligns with but exceeds the ultra-low emission standards mandated by the foundry industry, paving the way for a cleaner, greener production environment.
