Product Description
Introducing the remarkable S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a groundbreaking innovation in the field of sand grain rejuvenation. This state-of-the-art machine is engineered with a robust double-axis mechanism that efficiently removes the resin curing agent lingering on sand grain surfaces through advanced dynamic rubbing and intricate de-filming processes. Experience a new era of sand recycling efficiency with this marvel of engineering.
Enhancing its performance, the machine's base is equipped with a powerful high-performance fan that expertly extracts any remaining old film and dust, ensuring immaculate cleanliness. Post-treatment, the rejuvenated old sand emerges with superior integrity and beautifully rounded grains. This enhanced quality remarkably reduces the need for additional liquid materials during subsequent mixing, ensuring a more cost-effective and efficient process overall. Discover the future of sand recycling with the S53 Scrubber Recycling Machine.
As the pivotal equipment for regenerating foundry old sand, the strong rubbing regeneration machine achieves efficient stripping and regeneration of old sand types such as resin sand and water glass sand. This is accomplished through the synergistic effects of dual-axis mechanical rubbing and airflow assistance. Below is a comprehensive analysis covering 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 rotating in opposite directions at high speed (720-970r/min). These are equipped with wear-resistant alloy blades or cast iron rubbing discs on the shaft. As sand enters the regeneration chamber, it undergoes continuous rubbing and collision facilitated by the linear shear force and convection of the blades. This advanced mechanical action not only strips 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 traditional three-axis structures, the dual-axis design optimizes chamber space, increasing material throughput by 10-30t/h while simultaneously reducing energy consumption.
2. Boiling airflow assists film stripping. The bottom blower (air volume > 3700m³/h) injects adjustable airflow into the chamber through a boiling orifice plate, creating a fluidized environment of sand and air mixing. This enhances sand particle collision frequency while efficiently expelling detached inert film and dust through the dust removal vent. This "mechanical + airflow" dual methodology boosts the film stripping rate to over 80%, while the sand temperature drops by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The rubbing blade is crafted using a carbide convex rib welding process, enhancing wear resistance by more than threefold. The chamber body and frame are connected through rubber elasticity, effectively curbing vibration caused by high-speed operation and ensuring equipment stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: The brittle resin film is fully removed after 180 seconds of rubbing. Burning loss is minimized to less than 1.0%, and the tensile strength of regenerated sand is restored to 90% of new sand quality, setting a high standard in regeneration.
Water glass sand: Requires combination with wet regeneration (sand-water ratio 1:1.5) or low-temperature freezing centrifugal process (-40ºC). However, dry regeneration as a pretreatment significantly reduces the subsequent wet load, optimizing the overall process.
Alkali phenolic resin sand: The tough film necessitates higher rubbing strength, such as wheel rolling pressurization. Post-regeneration, the sand particles exhibit improved roundness, and gas emission is reduced by 30%, exemplifying environmental efficiency.
5. Technical advantages and economy
The regeneration efficiency is significantly enhanced. Compared to traditional centrifugal regeneration machines (power 22kW/stage) or airflow impact equipment, the unit energy consumption of the double-axis regeneration machine is reduced by 40%. The sand particle crushing rate is controlled within 5%, and its integrity surpasses that of vibration regeneration, showcasing superior performance and economy.
