Product Description
Introducing the Revolutionary S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a trailblazer in the realm of sand grain revitalization. This groundbreaking apparatus masterfully employs a robust double-axis mechanism to precisely eliminate resin curing agents that reside on the surface of sand grains. Through dynamic rubbing and sophisticated de-filming processes, this machine ensures unparalleled rejuvenation efficiency, setting a new standard in sand grain treatment.
Elevating its performance to new heights, the machine's base is strategically equipped with a high-performance fan that skillfully separates the remaining old film and dust, ensuring immaculate cleanliness. Following this meticulous process, the rejuvenated sand emerges with remarkable integrity and beautifully rounded grains. This superior quality significantly reduces the need for additional liquid materials during subsequent mixing stages, resulting in a more cost-effective and streamlined process. Discover the future of sand recycling excellence with the S53 Scrubber Recycling Machine.
As the cornerstone technology for the regeneration of foundry old sand, this powerful rubbing regeneration machine achieves the efficient stripping and regeneration of old sand, including resin sand and water glass sand. By harnessing the synergistic effect of dual-axis mechanical rubbing and airflow assistance, the following analysis explores its technical principles, structural design, process flow, and exceptional application effects:
1. Technical Principles and Core Mechanisms
The dual-axis regeneration machine operates with two sets of transmission main shafts rotating in opposite directions at high speeds, reaching up to 720-970r/min. Equipped with wear-resistant alloy blades or cast iron rubbing discs, these components are expertly positioned on the shaft. As sand enters the regeneration chamber, it undergoes repeated rubbing and collision under the linear shear force and convection generated by the blades. This mechanical action not only effectively removes the resin film and curing agent from the sand's surface but also achieves surface rounding through inter-particle friction, minimizing edge damage. Compared to the traditional three-axis structure, the dual-axis design optimizes chamber space, enhances material throughput by 10-30t/h, and simultaneously reduces energy consumption.
2. Boiling Airflow Assists in Film Stripping. The strategically placed bottom blower, with an air volume exceeding 3700m³/h, injects adjustable airflow into the chamber via the boiling orifice plate, creating a fluidized sand-air environment. This airflow not only enhances the collision frequency between sand particles but also ensures the efficient discharge of detached inert film and dust through the dust removal vent. This 'mechanical + airflow' dual effect elevates the film stripping rate to over 80%, and the sand temperature is effectively reduced by 30-50ºC.
3. Wear-Resistant and Vibration-Reducing Design. The rubbing blade utilizes a carbide convex rib welding process, enhancing wear resistance by more than threefold. The chamber body and frame are connected with rubber elasticity to effectively dampen vibrations induced by high-speed operations, ensuring the stability and reliability of the equipment.
4. Applicable Sand Mold and Regeneration Effect
Furan Resin Sand: The brittle resin film is effectively removed through 180 seconds of expert rubbing, resulting in a burning loss of less than 1.0%, while the tensile strength of regenerated sand is restored to an impressive 90% of that of new sand.
Water Glass Sand: Requires a combination with wet regeneration (sand-water ratio of 1:1.5) or a low-temperature freezing centrifugal process (-40ºC). However, employing dry regeneration as a pretreatment can significantly reduce the subsequent wet load, optimizing the entire process.
Alkali Phenolic Resin Sand: The resilient film demands higher rubbing strength, such as wheel rolling pressurization. Post-regeneration, the roundness of sand particles is significantly improved, with a 30% reduction in gas emission, underscoring the environmental efficiency.
5. Technical Advantages and Economy
Revolutionizing regeneration efficiency, this cutting-edge machinery surpasses traditional centrifugal regeneration machines (22kW/stage power) and air flow impact equipment. It achieves a 40% reduction in unit energy consumption, maintains the sand particle crushing rate within 5%, and ensures integrity superior to vibration regeneration, all while delivering enviable operational economy.
Achieve remarkable production cost optimization with our state-of-the-art mechanical rubbing and coated sand regeneration technology. By minimizing the resin active film residue of the regenerated sand to an impressive less than 0.3%, you can significantly lessen the need for curing agents by an outstanding 30%-50% during the sand mixing process. Furthermore, transform your operations with a revolutionary improvement in the sand-iron ratio, transitioning from the traditional 1:1 to a more efficient 1:1.5. This cutting-edge advancement not only streamlines your processes but also dramatically reduces the expenditure associated with purchasing new sand, ensuring a more cost-effective and efficient production cycle.
Embrace the future of environmental compatibility with our innovative dry regeneration system, meticulously designed to operate without the discharge of wastewater. Our sophisticated pulse back-blowing dust removal system ensures centralized processing of dust, achieving an exceptional dust removal efficiency of over 99%. This advanced technology not only aligns with but exceeds the stringent ultra-low emission standards set by the foundry industry. By integrating our system, you are taking a significant step towards a sustainable, eco-friendly operation that prioritizes environmental responsibility while maintaining superior performance.
