Product Description
This incredible machinery offers the remarkable capability of secondary regeneration, boasting a demoulding rate of no less than 25%, while achieving an impressive old sand recovery rate of 90% or more. A true marvel in sustainable sand management!
Utilizing the innovative turbo regeneration principle, this state-of-the-art machine excels in using friction between sand particles to efficiently strip away coatings and refine sand grains. As sand is processed, it forms an automatic protective cushion layer within the regeneration basin, safeguarding against wear and tear, and ensuring superior sand regeneration. The robust design, featuring lateral mounted throttle plates, assures reliable sand regeneration without breakage, resulting in improved grain roundness and uniformity. Recycled sand effectively reduces the necessity for additional liquid materials, and a secondary air separation mechanism efficiently eliminates inert films and dust, optimizing the recycling process to its best!
Built with a sophisticated secondary regeneration mechanism, this machine seamlessly channels the regenerated old sand into the subsequent basin for further processing. Following secondary regeneration, the sand is conveyed to the air separator section, ensuring complete processing for maximum efficacy.
1. Technical principle and core design
Turbine regeneration dynamics and sand interaction mechanism
This equipment leverages the turbocharged regeneration principle, where dual-axis high-speed rotation (achieving speeds of 720-970r/min) and specialized rubbing blades create a fluidized sand cushion in the regeneration basin. The intensified friction between sand particles, enhanced by self-organizing sand cushions, adeptly peels off resin films (achieving a mold release rate of 25% or higher), while preventing sand particle breakage (with a crushing rate of less than 5%). Impressively, sand particle roundness is bolstered by over 30%. This mechanism, inspired by the pressurized rubbing technology of Japan's Shinto Co., Ltd., and combined with Luohe Shengmei's patented shock-absorbing bearing seat design, ensures stable and efficient high-speed operation.
2. Secondary regeneration classification system
First-level regeneration basin: As old sand enters through the feed port, it undergoes effective rubbing by dual-axis blades, coupled with bottom boiling wind (air volume of 3N m³/min), facilitating initial film removal. With the innovative side throttle plate, inert film and dust are channeled to the dust removal system, ensuring pristine sand processing.
Secondary regeneration basin: Sand particles that require further treatment gravitate to the secondary basin. Here, the anti-wear refraction baffle and adjustable gap grinding disc design play a pivotal role. Through multiple refractions, the sand flow interacts with the panel, achieving deep film stripping. The airbag cylinder support structure adeptly avoids hard objects, safeguarding equipment components for long-lasting durability.
Air separation optimization system
Post-secondary regeneration, sand particles are introduced to a multi-stage air selection device. Here, controllable airflow (0.3-0.5MPa) generated by a powerful centrifugal fan (15-22kW) separates micro powder <0.106mm and residual inert film, elevating the old sand recovery rate to an exceptional 90% or more, with ignition loss kept under 1.0%. This ingenious design synergistically combines Qingdao Binhai Jincheng Company's boiling bed technology with Shengquan Group's airflow classification expertise, ensuring unmatched performance.
3. Key technological innovations
Wear-resistant and shock-absorbing collaborative design
Crafted for longevity, the rubbing blades are reinforced with tungsten carbide hard alloy, guaranteeing an impressive service life exceeding 8,000 hours, delivering exceptional durability and reliability.
Ingeniously designed bearing seats feature a spring layered buffer structure, achieving a vibration transmission attenuation rate of over 60%. This innovative solution effectively addresses the problem of sealing failures caused by vibration in conventional equipment, ensuring unwavering performance.
Intelligent control and energy efficiency optimization
Precision is at the heart of this machine. By adjusting the lower grinding disc guide nut, a precise gap of 0.5-3mm is attainable, adapting seamlessly to various sand types (for instance, alkaline phenolic resin sand demands a higher gap), ensuring optimal control and energy efficiency.
