01 Cost-Efficient Investment
A large steel silo adopts a ring wall foundation, which fully considers the mechanical characteristics of the rotating thin film steel plate structure body and loose stickiness of materials to the walls of the steel silo; the height to diameter ratio of a large steel silo is generally about 1:1, and the cylindrical structural design allows reasonable settlement. Since the soil is gradually consolidated and the bearing capacity is gradually improved under the action of pressure, the gradual step-by-step preloading method is adopted to finally meet the bearing capacity requirements. As for uniform geological features where the bearing capacity of the foundation is close to the desired level, simple and low-cost foundation treatment schemes can be used, such as dynamic compaction, CFG piles, and composite foundation.
02 Large Storage
The diameter of a single steel silo is from φ10m to φ80m, and the storage of one warehouse is from 200 cubic meters to 100,000 cubic meters.
03 Short Construction Period
The workload of constructing a steel silo is mainly the welding of steel plate structures, which often lasts for 120 days. Since multiple warehouses can be constructed simultaneously or alternately, the number of warehouses to be constructed has little impact on the construction period. Comparatively, a traditional concrete warehouse needs to go through a complex procedure including binding reinforcement, formwork, pouring, slipform, and maintenance. The construction period of one single steel silo is 60 days shorter than that of a traditional concrete warehouse under the same condition. The amount of construction period saved from constructing multiple warehouse clusters is increased proportionally.
04 High Safety
The structure of steel silos conforms to the latest national regulations and atlas regulations. The warehouse body fully considers the seismic intensity, ground resistance, wind load, snow load, temperature difference, corrosion allowance, rainfall, material bulk density, steel plate weight and other adverse factors, and adopts ring and vertical stiffening, column, roof truss or grid structure. The structure is validated by major structure calculation software such as pkpm and sap2000, and the company has maintained long-term cooperation with many large design institutions, so that the safety and stability of our steel silos can be ensured.
05 High Emptying Rate
The unloading system is based on our three key invention patents, namely the “Multi-point and Multi-lane Energy-saving Environmentally-friendly Warehousing Equipment and Discharge Method” (patent number: ZL 2015 1 0623265.1), the “Internal Activating and Flow Aid Device for Energy-saving and Environmentally-friendly Warehousing Equipment” (patent number: ZL 2015 1 0586435.9), the “Arch Breaker System for Powder Materials Used in Energy Saving and Environmentally Friendly Warehousing Equipment” (patent number: ZL 2015 1 0623262.8), so as to ensure the high emptying rate of the large steel silo. The large steel silo divides the warehouse into several discharge areas, and each discharge area is a discharge point. Each discharge area is filled and formed with fillers; the angle of the cone slope is controlled at 20° to 65°; the slope is provided with a fluidized tube; the junction of the warehouse wall and the slope is provided with a circular fluidized tube; the fluidized tubes set on the slope connecting the warehouse wall to the outlet are densified to minimize the dead zone in the warehouse. A high-pressure arch-breaking and flow-aid device is set at the discharge outlet in the warehouse. An arch breaker is equipped at each material accumulation point where materials easily amass. The device is activated to effectively solve the problem that the materials arch and the flow is blocked.
06 Large Output
The output volume of a single warehouse is stable and adjustable from 50 cubic meters to 800 cubic meters. A manual valve and an electric adjustment valve are provided at the bottom of the warehouse to freely adjust the flow rate in conjunction with the automatic control system. The discharge method relies on both the gravity and the pneumatic force. The output is less affected by the air volume, wind pressure of Roots blowers and the material level of the warehouse, allowing it to stably control the discharge. Moreover, when the equipment fails subsequently, the valve can be quickly closed to stop the material feeding, and the conveying equipment, discharge valve, and activated fan can be interlocked.
07 Low Operating Cost
The technical layout of the large steel silo is flexible, the discharge lane can rotate by 360 degree, and the inlet and outlet can be arranged at will. According to the design, the discharge can be achieved by the surge tube or the chute. Materials at high level can be conveyed outward by means of gravity discharge and arch breaker, which greatly reduces the energy consumption; a blower of low pressure and low air volume is equipped at the discharge air source. There is no equipment running in the warehouse thus ensuring low failure rate and greatly lowering the overall operating cost of the steel silo.
08 Energy-saving and Environmentally-Friendly
The steel silo is an air-tight container. The air supply can only be made with the Roots blower, the feed chute, or the bulk cement truck. The water content is low because the moisture is transported out with materials in gasified air supply, and drawn away in the air supply by feed chute or bulk cement trucks. Therefore no water-containing gas will remain in the warehouse. The surface of the steel plate is smooth and dense, and will not cause wall built-up and water seepage that will cause materials to harden and deteriorate. The steel silo applies tubes or chutes in input and output. A special bulk loader is used. The entire process is sealed. Dust collectors are provided at each dust point, which fully meets the national environmental protection requirements and achieves the purpose of energy conservation and environmental protection.
Based on the intelligent Internet of Things and the industrial cloud platform, Yuanfeng adopts an intelligent warehousing operation and maintenance system to collect the full information of steel silos. The client terminal on computer and mobile phone allows for operation status diagnosis and maintenance; real-time monitoring of energy consumption; data collection and analysis; centralized management of incoming and outgoing materials in the warehouse. With the advent of the “Industry 4.0” era, the Internet of Things, intelligentization and interconnection become the basis of making steel silos smarter. It deeply integrates the Internet of Things, cloud computing, big data, mobile Internet and other technologies with traditional industries, making steel silos more energy-saving, environmentally friendly and safer.
