Product Description
Introducing the revolutionary S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a true innovation in the realm of sand grain rejuvenation. This cutting-edge machine features a robust double-axis mechanism that skillfully eradicates the resin curing agent lingering on sand grains with dynamic rubbing and sophisticated de-filming processes, setting new standards in sand regeneration technology.
Bolstering its efficiency, the machine's foundation is equipped with a high-performance fan that proficiently separates residual old film and dust, achieving unmatched cleanliness. Post this meticulous treatment, the rejuvenated old sand exhibits remarkable integrity and perfectly rounded grains. This superior quality notably minimizes the requirement for additional liquid materials during subsequent mixing processes, offering a more cost-effective and efficient operation. Embrace the future of sand recycling with the S53 Scrubber Recycling Machine and transform your sand regeneration process into a seamless and economical endeavor.
As the quintessential machinery for the regeneration of foundry old sand, the vigorous rubbing regeneration machine achieves the efficient stripping and rejuvenation of old sands such as resin sand and water glass sand. This is accomplished through the synergistic effect of dual-axis mechanical rubbing and airflow assistance. Below is an in-depth analysis from the perspectives of technical principles, structural design, process flow, and real-world application effects:
1. Technical principles and core mechanisms
The dual-axis regeneration machine operates using two sets of main transmission shafts rotating in opposite directions at impressive speeds (reaching 720-970r/min). Equipped with wear-resistant alloy blades or cast iron rubbing discs, these shafts ensure that once the sand enters the regeneration chamber, it undergoes relentless rubbing and collision under the linear shear force and convection of the blades. This mechanical action effectively strips the resin film and curing agent off the sand surface while achieving surface rounding through friction between sand particles, reducing edge damage. Compared to the traditional three-axis structure, the dual-axis design optimizes chamber space, increases material throughput by 10-30t/h, and simultaneously reduces energy consumption, marking a leap in regeneration technology.
2. Boiling airflow assists film stripping. The bottom blower, with an air volume exceeding 3700m³/h, injects adjustable airflow into the chamber through a boiling orifice plate, creating a fluidized environment of sand and air mixing. This airflow not only enhances the collision frequency between sand particles but also ensures that the detached inert film and dust are efficiently discharged through the dust removal vent. This synergized 'mechanical + airflow' effect propels the film stripping rate to over 80%, while reducing the sand temperature by an impressive 30-50ºC, redefining standards in film stripping efficacy.
3. Wear-resistant and vibration-reducing design. The rubbing blade utilizes an advanced carbide convex rib welding process, enhancing wear resistance by more than threefold. The chamber body and frame are interconnected with rubber elasticity to effectively mitigate vibrations caused by high-speed operations, ensuring the equipment's stability and durability.
4. Applicable sand mold and regeneration effect
Furan resin sand: Within 180 seconds of rubbing, the brittle resin film is efficiently removed, maintaining a burning loss of less than 1.0%, while the tensile strength of the regenerated sand is restored to an impressive 90% of that of new sand.
Water glass sand: It necessitates a combination with wet regeneration (sand-water ratio 1:1.5) or a low-temperature freezing centrifugal process at -40ºC. However, employing dry regeneration as a pretreatment significantly reduces the subsequent wet load, optimizing the overall process.
Alkali phenolic resin sand: The resilient film demands heightened rubbing strength akin to wheel rolling pressurization. Post-regeneration, the roundness of sand particles is enhanced, and gas emission is reduced by a notable 30%, advancing environmental considerations.
5. Technical advantages and economy
Regeneration efficiency is markedly enhanced. In stark contrast to traditional centrifugal regeneration machines (power rated at 22kW/stage) or airflow impact equipment, the double-axis regeneration machine reduces unit energy consumption by an impressive 40%. The sand particle crushing rate is maintained within 5%, and its integrity surpasses that of vibration regeneration, making it a formidable choice in sand regeneration technology.
Unlock the potential for unmatched production cost optimization with our advanced solution! The resin active film residue in our regenerated sand is maintained at an impressive <0.3%. This allows for a remarkable reduction in curing agent usage by 30% to 50% during the sand mixing process. Furthermore, the improved sand-iron ratio, now refined from 1:1 to 1:1.5, facilitates a substantial decrease in the cost of purchasing new sand. Experience significant savings and enhanced efficiency with our cutting-edge technology.
Experience unparalleled environmental compatibility with our dry regeneration solution, designed to operate without any wastewater discharge. Our system ensures that dust emissions are expertly managed using a highly efficient pulse back-blowing dust removal system, achieving a dust removal efficiency of over 99%. This exceptional performance aligns perfectly with the ultra-low emission standards required in the foundry industry, ensuring your operations are not only sustainable but also leading the way in eco-friendly innovation.
