Product Description
Bucket elevator is a national standard product. It is a modified product of d-type bucket elevator. It is suitable for vertical upward transportation of old sand, waste sand, new sand, cleaning iron shot and other granular, small block without grinding or semi-grinding powder materials. Its structure characteristic: the appearance size is small, the occupation area is little, the promotion height is big, the installation maintenance is convenient. There are two kinds of feeding methods: the receiving type and the taking type at the bottom. The material is transported to the top and discharged by centrifugal gravity.
The tensioning device of the improved bucket elevator is placed in the lower part with simple superstructure and convenient disassembly and installation. The machine is also equipped with a fine-tuning device, so that the tensioning adjustment is convenient. The feeding mode of this series bucket elevator has the connection type and the bottom take out type, the belt is a high-strength lifting belt, with the characteristics of tear resistance, impact resistance, wear resistance, corrosion resistance, no elongation, no deformation, etc. : the tail wheel structure is a mouse dragon type, to prevent sand from being squeezed into the belt, the head of the elevator is driven by a reducer.
In the sand processing process of foundry, metallurgy, building materials and other industries, the vertical conveying efficiency of old sand, waste sand, iron shot and other materials directly affects production continuity and cost control. As an upgraded product of D-type bucket elevator, the new national standard bucket elevator provides an efficient and reliable technical solution for bulk material transportation under high temperature and high wear conditions through the integration of structural optimization and intelligent control technology. This article will deeply analyze how this equipment enables the green and intelligent upgrade of sand processing technology from the dimensions of technical characteristics, casting scene adaptability, intelligent operation and maintenance system and industry benchmark cases.
1. Technological innovation and adaptability to casting scenarios
For the vertical transportation needs of materials such as old sand (containing iron bean impurities ≤5%) and waste sand (water content 3-8%) in the foundry workshop, this equipment has achieved technological breakthroughs through modular structure and wear-resistant drive system:
Efficient conveying system:
Centrifugal gravity unloading: Using a deep bucket hopper (volume 0.5-3.7L) and 2.5m/s high-speed drive, the material is accurately thrown into the discharge port at the top through the dual effects of centrifugal force (≥0.8g) and gravity, and the conveying efficiency reaches 50-150t/h.
Squirrel cage tail wheel structure: The bottom drive wheel adopts a split wheel rim design (material ZG40Cr), and the wheel groove surface is laser-clad with tungsten carbide coating (thickness 0.3mm) to prevent sand from embedding into the belt gap and extend the service life by 3 times.
Wear-resistant and long-lasting design:
High-strength lifting belt: EP400/3-layer rubber belt (tensile strength ≥15kN/m) embedded with steel wire rope core, tear resistance increased by 60%, suitable for conveying highly abrasive materials such as iron shot (Mohs hardness 7).
AR wear-resistant lining: HB400 wear-resistant steel plate is laid on key parts of the casing, with annual wear <0.2mm, and maintenance cost is reduced by 70% compared with ordinary Q235 steel plate.
Intelligent adjustment technology:
Gravity automatic tensioning: The bottom is equipped with a constant force spring tensioning device to compensate for the belt elongation in real time (accuracy ±2mm), avoid the risk of slipping or chain derailment, and adapt to temperature fluctuations of -20ºC~120ºC.
Frequency conversion drive system: reduction motor + vector inverter combination, supports 0.5-4m/s stepless speed regulation, and accurately matches the sand supply rhythm of the molding line (error <0.5s).
2. Full-process integrated solution for foundry sand treatment
The equipment can be deeply integrated into the four core process links of sand dropping-screening-regeneration-sand mixing:
Old sand recovery system:
Linked with the vibrating sand dropping machine, it realizes the automatic unpacking of the sand box after pouring, the iron bean separation rate is >98%, and the old sand recycling rate is increased to 92%.
The closed material guide trough (leakage rate <5mg/m³) is matched with the pulse dust removal interface, and the dust concentration in the working area is <1mg/m³, which meets the GB 16297-1996 environmental protection standard.
New sand supply system:
Dual-mode feeding design:
Receiving type: adapted to the continuous sand supply at the outlet of the sand mixer, the flow fluctuation rate is <3%;
Bottom removal type: intermittent feeding of the sand storage is controlled by the pneumatic gate, with an accuracy of ±1kg/batch.
Iron shot circulation system:
The hopper is lined with ultra-high molecular weight polyethylene (UHMW-PE), and the surface friction coefficient is <0.15, which reduces the collision loss during the iron shot transportation process (crushing rate <0.5%).
3. Comparison of core advantages and economic benefits
Compared with the traditional D-type bucket elevator, this equipment has achieved a leap in efficiency through material innovation and intelligent operation and maintenance:
Energy consumption optimization:
Permanent magnet synchronous motor + energy feedback system, the power consumption per ton of sand is reduced from 1.8kW·h to 0.9kW·h, and the annual electricity bill is saved by more than 500,000 yuan (calculated based on an annual output of 100,000 tons).
Maintenance convenience:
Quick-detachable hopper bracket design, the time required to replace a single hopper is less than 10 minutes;
The head inspection door is equipped with a gas spring assist device, and a single person can complete the bearing lubrication operation.
Quality improvement data:
The fluctuation of the moisture content of the molding sand is reduced from ±1.2% to ±0.5%, and the porosity defect rate of the casting is reduced by 60%;
The overall equipment efficiency (OEE) reaches 94.5%, and the time between failures (MTBF) is greater than 30,000 hours.
