Product Description
Experience the future of foundry technology with Qingdao Sanzhuji Technology Co., Ltd.'s Fully Customized Knockout Barrel featuring unparalleled Installation Guidance and Support! As the mold within the sand box ascends and gracefully descends by its own weight, it reaches the bottom of the sleek box. The sand mold and casting seamlessly separate, gliding through the simplified box grid, guided by the intricate spiral plates. Here, the sand rejoins the old sand system, while the casting elegantly exits through the discharge port, ensuring precision and efficiency.
In the dynamic realm of the foundry workshop's sand-falling section, the swift and efficient detachment of sand molds and castings dictates the production rhythm and the supreme quality in recycling old sand. Our cutting-edge spiral guide sand-falling system revolutionizes the process through innovative structural design and intelligent control technology. It masterfully achieves the non-destructive separation of castings and guarantees the precise recovery of old sand. This comprehensive analysis reveals how our groundbreaking equipment enables foundries to embrace clean production, minimize costs, and elevate efficiency. With three phenomenal breakthroughs—harnessing gravitational potential energy with unparalleled efficiency, achieving lossless separation of castings, and pioneering intelligent regeneration of used sand—our equipment stands as a beacon of innovation for modern foundries.
1. Technical principle and core component design
Our system leverages the distinct physical properties of sand molds (compressive strength 0.8-1.2MPa) and castings (massive weight range of 50-5000kg) to achieve seamless separation through the harmonious interplay of gravity impact and spiral guidance:
Rotation and tipping mechanism:
Powered by a precision-driven servo motor, the sand box elegantly rotates to an optimal angle between 45°-75° (with an incredible error margin of ±0.5°). This rotation enables the castings and sand molds to impact the bottom plate of the simple box with gravity acceleration (4.5-6m/s²), achieving an astonishing initial separation efficiency of 98%.
Enhancing durability, the bottom of the simplified box is coated with robust AR450 wear-resistant steel plate (20mm thick), which not only triples the impact resistance but also ensures a remarkable service life exceeding 5 years.
Spiral guide system:
Our innovative multi-layer involute spiral plates (pitch range 300-800mm) expertly guide the sand flow into a vortex motion, achieving unparalleled secondary crushing through particle friction (friction angle 32°-35°), with a molding sand residual rate impressively below 0.5kg.
The guide plate's surface is enhanced with a cutting-edge tungsten carbide coating (0.2mm thick), significantly reducing the friction coefficient to μ<0.15, perfectly adaptable for various molding sands such as resin sand and water glass sand.
Intelligent sorting module:
Equipped with a sophisticated double-layer vibrating screen at the old sand outlet (aperture Φ5mm/Φ0.2mm), our module skillfully separates iron bean impurities (>5mm) and micro powder (<0.2mm), resulting in an exceptional old sand regeneration qualified rate of over 95%.
Our casting slide is augmented with a state-of-the-art visual inspection system (boasting 5 million pixels) to meticulously identify casting integrity in real time, ensuring defective products are automatically directed to the rework line for optimal quality control.
2. Process advantages and economic benefits
Compared to conventional vibrating sand-falling machines, our revolutionary system delivers a quantum leap in efficiency through strategic energy optimization and modular design, setting new standards in the industry:
Improved separation quality:
With a remarkable reduction, the amount of residual sand on the casting surface measures less than 0.3g/cm², which is an impressive 80% less than traditional pneumatic impact equipment, leading to a substantial 60% reduction in subsequent cleaning costs.
Maintaining an impeccable standard, the loss on ignition (LOI) of old sand is meticulously controlled at ≤3.5%, boosting the reuse rate to an extraordinary 92%, while reducing the need for new sand replenishment by an impressive 50%.
Record-breaking low energy consumption:
Our system's innovative design optimizes gravitational potential energy usage to reach an astounding 85%, with power consumption per ton of casting separation kept at an efficient ≤1.2kW·h, saving a staggering 45% of energy compared to conventional vibrating sand-falling machines.
Experience the perfect blend of performance and ecology with our cutting-edge solution! Our advanced designs ensure impact noise levels remain at a serene ≤78dB(A), while maintaining dust concentration at a minimal <5mg/m³. Delight in a 70% reduction in environmental protection costs, proving that efficiency and eco-friendliness can coexist harmoniously.
Unleash the future of industrial innovation with our state-of-the-art Intelligent Operation and Maintenance System:
Introducing our revolutionary predictive maintenance module, your ultimate guardian for operational efficiency. It vigilantly monitors the bearing temperature, ensuring it stays below the critical alarm threshold of 85ºC, while analyzing the vibration spectrum in real-time. Stay ahead of potential issues with fault warnings issued a full 7 days in advance, providing peace of mind and seamless operations.
Utilize the power of our sophisticated digital twin platform to achieve unparalleled precision. By simulating the optimal tipping angle for various casting weights ranging from 100-3000kg, we ensure a remarkable separation efficiency fluctuation rate of less than 2%. Elevate your processes to new heights of accuracy and reliability with our groundbreaking technology.
