Product Description
Unveiling the cutting-edge S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a true revolution in the realm of sand grain rejuvenation. This pioneering machine showcases a formidable double-axis mechanism that adeptly eradicates the resin curing agent clinging to sand grains' surfaces through dynamic rubbing and advanced de-filming techniques, ensuring unparalleled cleanliness and efficiency.
Elevating its performance, the machine's foundation is skillfully equipped with a high-efficiency fan that meticulously separates residual old film and dust, delivering immaculate purity. Following this comprehensive treatment, the revitalized old sand exhibits remarkable structural integrity and a beautifully rounded grain profile. This superior quality notably reduces the necessity for additional liquid materials during subsequent blending, ensuring a more economical and streamlined process. Embark on a journey into the future of sand recycling with the exceptional S53 Scrubber Recycling Machine.
As the quintessential apparatus for the revitalization of foundry old sand, the formidable rubbing regeneration machine achieves the proficient stripping and rejuvenation of old sand varieties like resin sand and water glass sand through the harmonious interplay of dual-axis mechanical rubbing and airflow assistance. Below is an in-depth exploration of its technical principles, structural design, process flow, and real-world application success:
1. Technical principles and core mechanisms
The dual-axis regeneration machine employs dual sets of high-speed counter-rotating transmission main shafts (reaching speeds of 720-970 r/min), with durable alloy blades or cast iron rubbing discs mounted on the shaft. Once the sand enters the regeneration chamber, it is subjected to repeated rubbing and collision fueled by the linear shear force and convection of the blades. This mechanical interaction not only efficiently removes the resin film and curing agent coating the sand's surface but also achieves surface rounding via inter-sand particle friction, minimizing edge degradation. In comparison to the traditional three-axis configuration, the dual-axis design maximizes chamber space, boosts material throughput by 10-30 t/h, and concurrently curtails energy consumption.
2. Boiling airflow enhances film stripping. The bottom blower (delivering airflow > 3700m³/h) injects adjustable airflow into the chamber via the boiling orifice plate, creating a fluidized environment of sand and air integration. This airflow dynamic not only heightens collision frequency among sand particles but also facilitates the expulsion of detached inert film and dust via the dust removal vent. This 'mechanical + airflow' dual impact elevates the film stripping efficiency beyond 80%, while reducing sand temperature by 30-50ºC.
3. Durable and vibration-reducing design. The rubbing blade features a carbide convex rib welding process, tripling its wear resistance; the chamber body and framework are conjoined through rubber elasticity to effectively mitigate the vibration induced by high-speed operation, thus guaranteeing equipment stability.
4. Applicable sand mold and regeneration outcomes
Furan resin sand: Notably brittle resin film can be completely removed within 180 seconds of rubbing, keeping the burning loss under 1.0%, while restoring the tensile strength of the regenerated sand to 90% of that of new sand.
Water glass sand: Requires integration with either wet regeneration (sand-water ratio 1:1.5) or low-temperature freezing centrifugal methodology (-40ºC), although pre-treatment through dry regeneration effectively reduces subsequent wet load.
Alkali phenolic resin sand: The resilient film necessitates increased rubbing intensity (such as wheel rolling pressurization), resulting in improved sand particle roundness post-regeneration and a 30% reduction in gas emissions.
5. Technical advantages and economical benefits
Regeneration efficiency is significantly enhanced. Compared to conventional centrifugal regeneration machines (power 22kW/stage) or airflow impact devices, the double-axis regeneration machine slashes unit energy consumption by 40%. Furthermore, the sand particle crushing rate is maintained below 5%, offering superior integrity compared to vibration-based regeneration processes.
