Product Description
Introducing the cutting-edge S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a remarkable innovation in the art of reviving sand grains. This state-of-the-art machine utilizes a powerful double-axis mechanism that skillfully eradicates resin curing agents from sand grain surfaces through dynamic rubbing and sophisticated de-filming techniques.
Increasing its operational efficiency, the machine's foundation is cleverly equipped with a high-performance fan that expertly separates any lingering old film and dust, ensuring immaculate cleanliness. Following this meticulous refinement process, the revitalized old sand exhibits an extraordinary level of integrity and exquisitely rounded grains. This superior quality significantly reduces the necessity for additional liquid materials during subsequent mixing, offering a more cost-effective and efficient production process. Embrace the future of sand recycling today with the S53 Scrubber Recycling Machine.
As the pivotal equipment for regenerating foundry old sand, the robust rubbing regeneration machine performs highly efficient stripping and rejuvenation of old sands such as resin sand and water glass sand using the synergistic combination of dual-axis mechanical rubbing and airflow assistance. Below is a detailed exploration 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 employs two sets of primary transmission shafts that rotate in opposite directions at high speeds (achieving speeds of 720-970r/min), with wear-resistant alloy blades or cast-iron rubbing discs mounted on the shafts. As sand enters the regeneration chamber, it is subjected to repeated rubbing and collision under the linear shear force and convection from the blades. This mechanical process not only strips resin films and curing agents from the sand's surface but also achieves surface rounding through friction between particles, minimizing 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.
2. Boiling airflow assists in film stripping. The base blower (air volume > 3700m³/h) injects adjustable airflow into the chamber via the boiling orifice plate, creating a fluidized environment of sand-air mixing. This airflow enhances the collision frequency among sand particles, while the detached inert film and dust are expelled through the dust removal vent. This "mechanical + airflow" dual effect elevates the film stripping rate to over 80%, and sand temperature can be decreased by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The design of the rubbing blade incorporates carbide convex rib welding, enhancing wear resistance by over three times. The chamber body and frame are connected with rubber elasticity, effectively mitigating vibrations caused by high-speed operations and ensuring equipment stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: The fragile resin film is removed through a 180-second rubbing process, with a burning loss of under 1.0%, and the tensile strength of the regenerated sand is restored to 90% of new sand.
Water glass sand: Requires integration with wet regeneration (sand-water ratio 1:1.5) or low-temperature freezing centrifugal process (-40ºC), with dry regeneration serving as a pretreatment to lessen the subsequent wet load.
Alkali phenolic resin sand: The resilient film demands heightened rubbing strength (such as wheel rolling pressurization). After regeneration, the roundness of sand particles is improved, and gas emissions are reduced by 30%.
5. Technical advantages and economic benefits
Regeneration efficiency is enhanced. In comparison to traditional centrifugal regeneration machines (power 22kW/stage) or airflow impact equipment, the unit energy consumption of the dual-axis regeneration machine is curtailed by 40%, while maintaining a sand particle crushing rate below 5%, with integrity surpassing that of vibration regeneration methods.
Production cost optimization is at the forefront of our innovative solutions. The remarkable On-Site Installation Guidance for Mechanical Rubbing and Regeneration offers a striking advantage: the resin active film residue of the regenerated sand is kept impressively low (<0.3%). This efficiency enables a substantial reduction in the amount of curing agent required—by 30% to 50%—when mixing sand. Furthermore, we redefine economic excellence by adjusting the sand-iron ratio from 1:1 to a more cost-effective 1:1.5, dramatically slashing the expenses associated with procuring fresh sand.
Environmental compatibility is an integral feature of our groundbreaking process. With our dry regeneration technology, wastewater discharge becomes a concern of the past. Our state-of-the-art approach ensures that dust is meticulously managed via a pulse back-blowing dust removal system, which boasts an exceptional dust removal efficiency exceeding 99%. This highly efficient system aligns with and surpasses the ultra-low emission standards that are a benchmark in the foundry industry.
