Silo capacity: 700 cubic meters; capacity weight: 525 tons; silo diameter: 8.25 meters; total height: 18.4 meters; silo cylinder height: 11.27 meters. 3. Casing material: Premium double-sided patterned galvanized steel plate with 275g/m² zinc coating on both sides. Roof plate: Aluminum-zinc coated steel plate thickness: Layer 1: 1.50mm, Layers 2-3: 1.0mm, Layers 4-6: 1.5mm, Layers 7-9: 2.0mm, Layer 10: 2.5mm. 4. External M-type galvanized columns, approximately 312mm wide. Column thickness: 3.0mm for layers 1-5, 4.0mm for layers 6-10. 5. Entire steel cone base painted. Column base material: H244×175. Tie rod material: 50×5 angle steel. Cone base plate thickness: δ4–5mm. 6. Silo top equipped with 1 manhole for maintenance. Silo cylinder equipped with 1 silo door. Inside silo: 1 vertical ladder. Outside silo: 1 vertical ladder from ground level to lower silo door. 7. Field installation. Silo corrugated panels are manufactured using cold-rolled profiles through punching, bending, and shearing production lines, ensuring high precision. Both silo roof and cylinder sections utilize Grade 8.8 high-strength galvanized bolts. Critical load-bearing areas employ Grade 10.9 high-strength galvanized bolt assemblies, with a service life of 30 years. | ||
| 2 | Silo Roof Ventilation System | SF4-2 | Set | 1 | 1.5 | 1.5 | Each silo roof is equipped with one SF4-2 axial fan (1.5 kW) for silo roof use. Features a rain cap, meets national standards, low-voltage design, rotational speed: 2800 r/min, total pressure: 380 Pa, airflow: 11000 m³/h. Removes moisture from the silo interior, includes fan base and cover; two sets of natural ventilation windows are installed. |
| 3 | Cone-bottom ventilation system | TF8.2 | Set | 1 | 7.5 | 7.5 | One unit per silo, 4-72-No.4.5A fan, 7.5 kW power rating per unit, national standard product, low-pressure fan, speed: 2900 r/min, total pressure: 1673-2554 Pa, airflow: 5730~10580 m³/h; Domestic motor, includes ventilation ring duct and cage-type ventilation pipe, pressure-resistant ring duct beneath silo, stamped-formed for more uniform ventilation, effectively preventing grain spoilage. |
| 4 | Temperature Measurement System | CW8.2 | Set | 1 | Armored temperature measurement cables are evenly distributed throughout the silo. The PLC touchscreen temperature monitor provides real-time temperature monitoring, automatic fan start/stop upon excessive temperatures, material level monitoring and alarms, historical temperature curve recording and storage, silo temperature control visualization, and equipment overload alarms. Temperature measurement range: 10°C–80°C, or: -55°C–125°C; Temperature measurement accuracy: ±1°C; Temperature measurement humidity: ±4.1%; Vertical spacing between temperature measurement points: 2m. Upon detecting anomalies, promptly ventilate to cool down or remove the grain from the silo. | ||
