Product Description
Introducing the revolutionary S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a true marvel in the realm of sand grain rejuvenation. This cutting-edge machine harnesses a powerful double-axis mechanism that skillfully eradicates the lingering resin curing agent from the surface of sand grains. Through dynamic rubbing and intricate de-filming processes, it achieves unparalleled levels of cleanliness and efficiency in sand recycling.
With its exceptional efficiency, the machine's base is ingeniously equipped with a high-performance fan that expertly expels lingering old film and dust, ensuring sand grains emerge immaculately clean. Following this meticulous process, the rejuvenated old sand boasts an impressive integrity and gorgeously rounded grains. This superior quality considerably reduces the necessity for additional liquid materials in subsequent mixing phases, offering a more cost-effective and streamlined process. Embrace the future of sand recycling with the S53 Scrubber Recycling Machine.
Serving as the pivotal equipment for the regeneration of foundry old sand, this robust rubbing regeneration machine effectively achieves the efficient stripping and rejuvenation of old sands, such as resin sand and water glass sand. This is accomplished through the harmonious synergy of dual-axis mechanical rubbing and airflow assistance. Below is a comprehensive analysis, detailing its technical principles, structural design, process flow, and real-world application effects:
1. Technical principles and core mechanisms
The dual-axis regeneration machine employs two sets of transmission main shafts that rotate in opposite directions at high speeds, reaching up to 720-970r/min. It is outfitted with wear-resistant alloy blades or cast iron rubbing discs on the shaft. As sand enters the regeneration chamber, it undergoes repeated rubbing and collision under the linear shear force and convection created by the blades. This mechanical action not only effectively removes the resin film and curing agent from the sand surface but also achieves superior surface rounding through the friction between sand particles, minimizing edge damage. Compared to traditional three-axis structures, the dual-axis design optimizes chamber space, boosting material throughput by 10-30t/h while simultaneously reducing energy consumption.
2. Boiling airflow assists film stripping. The bottom blower, with an air volume exceeding 3700m³/h, introduces adjustable airflow into the chamber via the boiling orifice plate, creating a fluidized mixture of sand and air. This airflow significantly increases the collision frequency between sand particles while efficiently expelling the detached inert film and dust through the dust removal vent. The 'mechanical + airflow' dual effect elevates the film stripping rate to over 80%, while reducing sand temperature by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The rubbing blade employs a carbide convex rib welding process, enhancing wear resistance by over threefold. Additionally, the chamber body and frame are interconnected with rubber elasticity, effectively mitigating vibrations caused by high-speed operations, ensuring the equipment's stability and longevity.
4. Applicable sand mold and regeneration effect
Furan resin sand: The brittle resin film is effectively removed through a 180-second rubbing process, resulting in a burn loss of less than 1.0%. The tensile strength of the regenerated sand is restored to an impressive 90% of new sand.
Water glass sand: Optimal results are achieved by combining with either wet regeneration (sand-water ratio of 1:1.5) or a low-temperature freezing centrifugal process (-40ºC). However, implementing dry regeneration as a pretreatment can significantly lower the subsequent wet load.
Alkali phenolic resin sand: This tough film demands heightened rubbing strength, such as wheel rolling pressurization. Post-regeneration, the roundness of the sand particles is notably improved, and gas emissions are reduced by an impressive 30%.
5. Technical advantages and economy
The regeneration efficiency is markedly enhanced. In comparison to traditional centrifugal regeneration machines (22kW/stage power) or air flow impact equipment, the unit energy consumption of the dual-axis regeneration machine is reduced by 40%. Additionally, the sand particle crushing rate is maintained within 5%, ensuring better integrity than vibration regeneration.
