Product Description
Empowered with a remarkable capability for secondary regeneration, this innovative system boasts a demoulding rate of ≥25% and an impressive old sand recovery rate of ≥90%, ensuring maximum efficiency and sustainability in your operations.
This machine harnesses the power of the turbo regeneration principle, ingeniously utilizing the friction between old sand particles to meticulously strip membranes and round off grains. As sand regenerates, it forms an automatic cushion layer within the basin, safeguarding against wear and tear. The powerful flow of sand impacts panels for a complete secondary regeneration, while a lateral throttle plate guarantees consistent and reliable sand rejuvenation. Remarkably, the sand maintains its integrity throughout, with improved roundness and uniformity. This recycled sand significantly cuts down the need for additional liquid material. The lower section hosts a secondary air separation mechanism to efficiently expel inert film and dust from the recycled sand.
Within this cutting-edge secondary regeneration mechanism, the upper basin seamlessly channels old sand into the subsequent regenerating basin. Following secondary regeneration, the revitalized sand transitions into the air separator section, ensuring precision and purity.
1. Technical principle and core design
Turbine regeneration dynamics and sand interaction mechanism
This state-of-the-art equipment employs the advanced turbocharged regeneration principle. Using dual-axis high-speed rotation (reaching 720-970r/min), it crafts a fluidized sand cushion in the regeneration basin. This enhances friction strength among sand particles through a self-organizing effect, allowing for effective resin film removal (mold release rate ≥ 25%) while preventing particle crushing (crushing rate <5%). Ultimately, achieve a 30% enhancement in sand particle roundness. This ingenious mechanism draws inspiration from Shinto Co., Ltd.'s pressurized rubbing technology and integrates the shock-absorbing bearing seat design patented by Luohe Shengmei, ensuring unparalleled stability even at high speeds.
2. Secondary regeneration classification system
First-level regeneration basin: Upon entering through the feed port, old sand is expertly rubbed by dual-axis blades and the invigorating bottom boiling wind (air volume 3N m³/min) to initiate film removal. The inert film and dust are then efficiently redirected to the dust removal system via the side throttle plate.
Secondary regeneration basin: Gravity guides untreated sand particles into the secondary basin. Here, the anti-wear refraction baffle and adjustable gap grinding disc design come into play. Sand flow impacts panels for multiple refractions, achieving profound film stripping. Concurrently, the airbag cylinder support structure adeptly avoids hard objects, preserving equipment integrity.
Air separation optimization system
Following secondary regeneration, sand particles enter the multi-stage air selection device, where a controlled airflow (0.3-0.5MPa) is generated by a centrifugal fan (power 15-22kW) at the base. This airflow meticulously separates micro powder <0.106mm and residual inert film, culminating in a commendable old sand recovery rate of ≥90% and ignition loss ≤1.0%. This design harmoniously merges Qingdao Binhai Jincheng Company's boiling bed technology with Shengquan Group's expertise in airflow classification.
3. Key technological innovations
Wear-resistant and shock-absorbing collaborative design
Rubbing blades are crafted from tungsten carbide hard alloy, offering an exceptional service life exceeding 8,000 hours, ensuring long-lasting performance and durability.
The bearing seat is ingeniously equipped with a spring layered buffer structure, boasting a vibration transmission attenuation rate of over 60%. This innovative design effectively addresses sealing failures due to vibration in traditional equipment.
Intelligent control and energy efficiency optimization
Through precise adjustment of the lower grinding disc guide nut, a 0.5-3mm gap can be accurately controlled to suit various sand types. For instance, alkaline phenolic resin sand requires a higher gap, offering adaptability and optimal performance.
