Product Description
Introducing the national standard bucket elevator, a refined evolution of the d-type bucket elevator that stands out for its adaptability and efficiency. Perfectly engineered for the vertical transport of materials like old sand, waste sand, new sand, and iron shots, this product excels with small granules or semi-grinding powder materials. What sets it apart are its compact structure and minimal footprint, yet it boasts remarkable lifting heights and ensures hassle-free installation and maintenance. With two feeding methods—receiving type and taking type—the material ascends to the top and discharges seamlessly through centrifugal gravity, marking a new era in convenient and effective material handling.
Our enhanced bucket elevator is equipped with an innovative tensioning device strategically positioned at the lower section, simplifying the superstructure and easing disassembly and installation processes. It also includes a precise fine-tuning mechanism for straightforward tension adjustments. The series offers versatile feeding modes, featuring connection type and bottom take-out type. The high-strength lifting belt resists tears, impacts, and wear, stands firm against corrosion, and maintains its integrity with no elongation or deformation. The tail wheel, designed with a mouse dragon structure, efficiently prevents sand intrusion into the belt, while a reducer-driven head ensures smooth operation.
In industries like foundry, metallurgy, and construction materials, efficient vertical conveyance of materials such as old sand, waste sand, and iron shots is crucial for seamless production and cost management. The newly upgraded national standard bucket elevator, a superior iteration of the D-type, delivers robust and dependable technical solutions for transporting bulk materials under extreme temperature and wear conditions. By merging structural optimization with intelligent control technologies, it champions the green and intelligent transformation of sand processing. This analysis delves into how the equipment’s technical prowess, scene adaptability, intelligent operations, and benchmark cases propel industry advancements.
1. Technological innovation and adaptability to casting scenarios
Tailored for the specific vertical transportation challenges found in the casting workshops, particularly with materials like old sand (containing iron bean impurities ≤5%) and waste sand (moisture content 3-8%), this equipment achieves remarkable technological strides through a modular structure and a drive system engineered for wear resistance:
Efficient conveying system:
Centrifugal gravity unloading: Featuring a deep bucket hopper (volume 0.5-3.7L) propelled by a high-speed 2.5m/s drive, the material is precisely projected into the top discharge port, guided by the dual forces of centrifugal force (≥0.8g) and gravity. This system achieves an impressive conveying efficiency of 50-150t/h.
Squirrel cage tail wheel structure: The innovative split wheel rim design (material ZG40Cr) is laser-clad with tungsten carbide coating (0.3mm thick), preventing sand from embedding into the belt gaps, extending the service life by threefold.
Wear-resistant and long-lasting design:
High-strength lifting belt: Incorporating an EP400/3-layer rubber belt with embedded steel wire rope core, boasting a tensile strength ≥15kN/m, this design enhances tear resistance by 60%, making it suitable for transporting abrasive materials like iron shots with a Mohs hardness of 7.
AR wear-resistant lining: Utilizing HB400 wear-resistant steel plates on critical casing areas, this feature ensures an annual wear of <0.2mm, reducing maintenance costs by 70% compared to traditional Q235 steel plates.
Intelligent adjustment technology:
Gravity automatic tensioning: Fitted with a constant force spring tensioning device at the base, this system compensates for belt elongation in real-time (accuracy ±2mm), effectively mitigating the risks of slipping or chain derailment and adapting to temperatures ranging between -20ºC and 120ºC.
Frequency conversion drive system: Integrating a reduction motor with a vector inverter, this advanced system supports 0.5-4m/s stepless speed regulation, precisely synchronizing with the molding line's sand supply rhythm (error <0.5s).
2. Full-process integrated solution for foundry sand treatment
Our equipment seamlessly integrates into the pivotal stages of the sand processing lifecycle: sand dropping, screening, regeneration, and sand mixing, ensuring optimal efficiency and performance.
State-of-the-Art Old Sand Recovery System:
In synergy with the advanced vibrating sand dropping machine, this system facilitates the effortless automatic unpacking of sand boxes post-pouring. Enjoy an impressive iron bean separation rate exceeding 98%, while boosting the old sand recycling efficiency to a remarkable 92%.
Our closed material guide trough minimizes leakage rates to an astonishing <5mg/m³. Coupled with our pulse dust removal interface, it ensures that dust concentration in the workspace remains below 1mg/m³, fully compliant with the stringent GB 16297-1996 environmental standards.
Cutting-Edge New Sand Supply System:
Ingenious Dual-Mode Feeding Design:
Receiving Type: Specifically engineered for consistent sand supply at the sand mixer's outlet, maintaining a flow fluctuation rate of less than 3%.
Bottom Removal Type: Achieve precision with our intermittent sand storage feeding, meticulously controlled by a pneumatic gate, boasting an accuracy of ±1kg per batch.
Efficient Iron Shot Circulation System:
Our hoppers are lined with ultra-high molecular weight polyethylene (UHMW-PE), showcasing a surface friction coefficient under 0.15. This innovation dramatically decreases collision losses during iron shot transport, reducing the crushing rate to a mere 0.5%.
3. Unveiling Core Advantages and Economic Gains
In comparison to the conventional D-type bucket elevator, our revolutionary equipment showcases unparalleled efficiency enhancements through groundbreaking material advancements and smart operation and maintenance strategies:
Revolutionary Energy Consumption Optimization:
Equipped with a permanent magnet synchronous motor and an energy feedback system, this marvel of engineering slashes power consumption per ton of sand from 1.8kW·h to a mere 0.9kW·h. This results in an astounding annual electricity cost saving of over 500,000 yuan, based on an annual output of 100,000 tons.
Effortless Maintenance and Servicing:
Our innovative quick-detachable hopper bracket design allows for the replacement of a single hopper in less than 10 minutes, maximizing uptime and productivity.
The advanced head inspection door, with its gas spring assist device, ensures that a single technician can efficiently perform bearing lubrication operations without hassle.
Exemplary Quality Improvement Data:
Thanks to our cutting-edge technology, the fluctuation in the moisture content of molding sand is significantly reduced from ±1.2% to an impressive ±0.5%. Additionally, the porosity defect rate of castings is slashed by an astonishing 60%.
Our equipment boasts an outstanding overall efficiency (OEE) of 94.5%, with a mean time between failures (MTBF) surpassing an incredible 30,000 hours, ensuring reliability and performance excellence.
