Product Description
Discover the revolutionary S53 Scrubber Recycling Machine, a pinnacle of innovation crafted by Qingdao Sanzhuji Technology Co., Ltd. This state-of-the-art marvel in sand grain rejuvenation is engineered with a powerful double-axis mechanism. It effectively eradicates the stubborn resin curing agent clinging to sand grains through a dynamic interplay of meticulous rubbing and advanced de-filming processes. Experience unparalleled excellence in sand regeneration with this cutting-edge technology.
Elevate your sand recycling process with enhanced efficiency, thanks to the machine's base, artfully equipped with a high-performance fan. This fan efficiently separates residual old film and dust, achieving immaculate cleanliness. Post-treatment, the rejuvenated sand emerges with an impressive integrity and beautifully rounded grains. This superior quality remarkably reduces the requirement for additional liquid materials during subsequent mixing, ensuring a more cost-effective and streamlined operation. Embark on a journey to the future of sand recycling with the unparalleled S53 Scrubber Recycling Machine.
As the pivotal equipment for the regeneration of aged foundry sand, this robust rubbing regeneration machine excels in the efficient stripping and renewal of old sand types, like resin sand and water glass sand. It achieves this through the powerful synergy of dual-axis mechanical rubbing enhanced by airflow assistance. Below is a comprehensive analysis from technical principles, structural design, process flow, to real-world application effects:
1. Technical principles and core mechanisms
The dual-axis regeneration machine is designed with two transmission main shafts rotating in opposite directions at astonishing speeds of 720-970r/min. These shafts are adorned with wear-resistant alloy blades or cast iron rubbing discs. As sand enters the regeneration chamber, it undergoes thorough rubbing and collision under the linear shear force and convection of the blades. This mechanical action not only effectively strips away the resin film and curing agent from the sand surface but also achieves surface rounding through inter-particle friction, minimizing edge damage. Compared to the conventional three-axis structure, the dual-axis design optimizes chamber space, boosts material throughput by a substantial 10-30t/h, and simultaneously reduces energy consumption.
2. Boiling airflow assists film stripping. The strategically positioned bottom blower, with an air volume exceeding 3700m³/h, injects adjustable airflow into the chamber via the boiling orifice plate. This creates a fluidized environment of sand and air mixture. On one hand, this airflow amplifies the collision frequency between sand particles. On the other, it expels the detached inert film and dust through the dust removal vent. This synergistic 'mechanical + airflow' dual-action elevates the film stripping rate to exceed 80%, while effectively reducing sand temperature by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The innovative rubbing blade employs a carbide convex rib welding process, boosting wear resistance by an impressive 3 times. Meanwhile, the chamber body and frame are connected through rubber elasticity, effectively dampening the vibrations caused by high-speed operation, thus ensuring the stability and durability of the equipment.
4. Applicable sand mold and regeneration effect
Furan resin sand: Experience the brittleness of the resin film being effortlessly removed with just 180 seconds of rubbing. The burning loss remains below 1.0%, and the tensile strength of the regenerated sand is impressively restored to 90% of new sand.
Water glass sand: Achieve optimal results by combining with wet regeneration (sand-water ratio of 1:1.5) or employing a low-temperature freezing centrifugal process at -40ºC. However, utilizing dry regeneration as a pretreatment effectively reduces the subsequent wet load.
Alkali phenolic resin sand: The tenacious film necessitates higher rubbing strength, such as wheel rolling pressurization. Post-regeneration, the roundness of sand particles is significantly enhanced, and gas emissions are reduced by a remarkable 30%.
5. Technical advantages and economy
Witness a monumental improvement in regeneration efficiency. In contrast to conventional centrifugal regeneration machines (power 22kW/stage) or airflow impact devices, the dual-axis regeneration machine reduces unit energy consumption by a notable 40%. Moreover, the sand particle crushing rate is meticulously controlled within 5%, offering superior integrity compared to vibration regeneration techniques.
Experience unparalleled production cost optimization with our exceptional technology: the resin active film residue in the regenerated sand is reduced to an impressive level of less than 0.3%. This advancement allows a remarkable reduction in the amount of curing agent required—achieving a diminishment of 30% to 50% during the sand mixing process. Furthermore, the sand-iron ratio is optimized from the conventional 1:1 to an efficient 1:1.5, dramatically slashing the expenses related to acquiring new sand. A smart choice for cost-conscious operations.
Embrace environmental stewardship with our cutting-edge dry regeneration process, which boasts exceptional environmental compatibility. Our innovative method eliminates wastewater discharge, ensuring a cleaner and greener process. The centralized pulse back-blowing dust removal system elevates cleanliness by achieving an outstanding dust removal efficiency of over 99%, aligning perfectly with the ultra-low emission standards required in the foundry industry. Step into the future of eco-friendly foundry operations with technology that cares for the planet.
