Coke Storage Silo
Description
Technical Parameters
Core Adaptability: Tailored for Coke Storage
Coke storage silos represent a specialized solution designed to address the unique characteristics of coke: high hardness, irregular particle size, and demanding permeability requirements. Through structural optimization and functional design, spiral steel silos perfectly accommodate the large-scale storage needs of coke raw materials in metallurgical and chemical industries. They can store various coke products such as metallurgical coke and foundry coke, with individual silo capacities ranging from 300 to 30,000 tons. Supported by silo clusters, they meet the centralized storage demands of large coking plants and steel enterprises.
Core Advantages
Wear Resistance + Structural Integrity
Tank walls are constructed from galvanized steel plates formed through spiral seam rolling, achieving seam strengths exceeding 150 MPa. This design withstands prolonged friction and impact from coke particles. The structure meets GB50011 design standards for wind load and seismic resistance, ensuring a service life exceeding 25 years.
Excellent Ventilation + Spontaneous Combustion Prevention
The silo roof incorporates specialized ventilation equipment and pressure relief valves. Combined with micro-slot structures in the silo walls, this creates natural ventilation circulation. It effectively expels harmful gases such as CO generated during coke storage, reducing the risk of spontaneous combustion. An optional temperature monitoring system can be added for real-time tracking of internal temperatures.
Low Storage Loss + Smooth Discharge
The silo's excellent sealing minimizes moisture absorption and oxidation losses, keeping the loss rate below 1%. The conical silo bottom, combined with wear-resistant liners and a vibrating discharge device, prevents coke accumulation and blockages. The discharge rate exceeds 95%, meeting the demands of continuous production feeding.
Controllable Costs + Efficient Construction
Compared to welded silos, construction time is reduced by 30%. Eliminates complex welding processes for simplified on-site installation. Low investment cost per unit volume. Flexible customization of diameter (3-30 meters) and height to suit site conditions, conserving land resources.
Structural Features
- The silo body features a cylindrical structure formed by continuous spiral-locked rolling of galvanized steel plates using specialized equipment. The seamless silo walls ensure high overall strength and excellent sealing, preventing coke dust leakage and rainwater infiltration.
- The silo roof features a conical or dome design, equipped with rain caps, ventilation ports, and maintenance access. Dust removal systems can be added to certain specifications, making it suitable for industrial sites with stringent environmental requirements.
- The silo base employs either a reinforced concrete conical foundation or a steel-framed support structure with a 30-45° slope. It interfaces with screw conveyors or chutes for direct connection to production conveying systems, enabling automated unloading.
Core Industry Value: - Addresses issues of extensive land use and contamination risks associated with open-air coke storage by centralizing sealed storage to reduce coke loss rates. - Ensures stable supply chain continuity for downstream production, minimizing production line downtime losses caused by raw material supply interruptions. - Features efficient construction and low maintenance costs, reducing storage operation expenses for enterprises and aligning with industrial-scale production demands.
