Product Description
The Customized Conveyer Shakeout and Knockout Machine with Turnkey Service plays a pivotal role in the initial phase of the old sand treatment system, seamlessly integrating the molding department with the sand treatment department. Designed for the efficient separation of molding sand and castings through vibration, this series of shakeout machines excels in high-temperature sand mold management, offering remarkable production efficiency at a reduced cost. With a focus on low energy consumption and robust environmental protection, it stands as a testament to advanced manufacturing prowess.
In today's modern foundry workshops, the streamlined separation of sand molds and castings marks the cornerstone of the old sand regeneration system, crucially influencing production cadence and resource efficiency. This innovative series of vibrating sand-falling machines delivers a groundbreaking, energy-efficient, and eco-friendly solution for processing high-temperature sand molds, harnessing cutting-edge vibration control and an intelligent sorting system. Dive deep into this article to explore the transformative impact of this equipment on foundries, emphasized through technological advancements, process integration, energy optimization, and industry applications. This range is distinguished by three monumental technological strides: Delta-Phase precise vibration, adaptability to high-temperature sand molds, and advanced intelligent sorting and regeneration.
1. Technical principles and core design breakthroughs
Leveraging the inherent physical traits of sand molds (compressive strength 0.8-1.5MPa) and castings (temperature 200-600ºC), this equipment achieves groundbreaking advancements with a combination of multi-frequency vibration and smart control systems:
Delta-Phase vibration technology
Utilizing variable angle vibration control (adjustable up to ±15°), this system meticulously aligns sand flow velocity and residence time by fine-tuning the vibration vector direction. The result is a sand particle separation efficiency exceeding 98%, a staggering 30% improvement over conventional inertial sand-falling machines.
Featuring a state-of-the-art permanent magnet synchronous motor and vector variable frequency drive system, it offers seamless vibration frequency adjustments between 10-25Hz, making it ideal for resin sand, water glass sand, and other molding sand variants.
High temperature sand processing system:
Crafted from ZG40CrMo heat-resistant steel casting, the vibration table withstands temperatures up to 800ºC. Enhanced with a tungsten carbide coating (0.3mm thick), it remarkably reduces high-temperature wear rates by 70%.
Incorporating a water-cooled interlayer (flow rate 5m³/h), the system adeptly maintains table temperatures below 80ºC, preventing the burning and hardening of molding sand.
Intelligent sorting module:
The innovation of a double-layer screening structure (upper layer aperture Φ10mm/lower layer Φ2mm), coupled with a pneumatic blowing device, facilitates the simultaneous separation of iron impurities (>10mm) and micro powder (<2mm), achieving an impressive >95% qualified rate in old sand regeneration.
Equipped with an infrared thermal imager, the system vigilantly monitors the casting's temperature field, dynamically adjusting vibration intensity (with an error margin of ±5%) to guarantee the flawless separation of thin-walled castings, ensuring a scratch rate below 0.1%.
The innovative vibration energy recovery system harnesses 30% of kinetic energy, converting it into electrical power to be fed back into the grid. With a power consumption of ≤1.5kW·h per ton of casting, the annual savings on electricity bills surpass 800,000 yuan, calculated with a production capacity of 100,000 tons.
Soft vibration isolation springs, boasting a dynamic load attenuation rate of over 90%, drastically slash infrastructure expenditures and curtail equipment installation areas by 40%.
2. Full-process integrated solution for casting sand processing
As a pivotal hub bridging molding and sand processing, this equipment orchestrates an intelligent closed-loop system encompassing sand fall, screening, cooling, and regeneration:
High-temperature sand mold processing:
Unwaveringly connected to the molding line outlet, it adeptly processes sand molds at temperatures reaching 600ºC with a sand-iron ratio (S/M) adaptation span of 5:1 to 60:1. Its impressive singular processing capacity ranges from 50-200t/h.
Our innovative closed material guide trough boasts an impressively low leakage rate of under 5mg/m³, seamlessly integrated with our state-of-the-art pulse dust removal system. This ensures that the dust concentration in the working area is kept at an exceptional <1mg/m³, contributing to a pristine work environment. Furthermore, with a noise level maintained at ≤78dB(A), our system is designed for optimal efficiency and worker comfort.
Pioneering in the intelligent regeneration of old sand:
Our advanced system efficiently handles the separated old sand by channeling it into the boiling cooling bed via a high-performance screw conveyor. This process significantly reduces the moisture content from 6% to an impressive 2.5%, while cooling the temperature from a high 150ºC down to a comfortable 35ºC. Such processing enhances the sand's reuse rate remarkably to 90%, embodying our commitment to sustainability and resource optimization.
The cutting-edge micro powder pneumatic conveying module, available as an option, adeptly transports fine sand particles <0.2mm to the 3D printing sand regeneration line. This ensures a remarkable achievement of zero waste discharge, reflecting our dedication to environmental responsibility and innovation.
Non-destructive and precise sorting of castings:
Equipped with a cutting-edge visual inspection system featuring a 5 million pixel resolution, our casting slide is engineered for excellence. It skillfully identifies any residue from the pouring head and detects surface defects in real time. This system automatically redirects them to the rework line, effectively increasing the yield rate by an impressive 15%, showcasing our commitment to quality and productivity.
