Comprehensive description of steel plate silo technology and performance

With the development of technology, the current trend in the construction of storage silos is: the capacity of individual silos is getting bigger and bigger; more and more complete functions. The capacity of the Steel Plate Silo is gradually increasing, its structural design, basic form, environmental emissions, natural factors (geology, hydrology, freezing, temperature, etc.), as well as the discharge form of the steel plate silo, energy consumption indicators and other investment costs per unit of volume are all factors considered by the builders.

 

Dazheng steel plate warehouse is widely used in the field of material storage and transfer because of its large capacity, high land utilization rate, high degree of automation, short construction period and low investment per unit volume.

1、Wedge force foundation technology: The wedge force pressurized foundation designed by utilizing the principle of wedge force pressurization is suitable for the construction of projects under different geological conditions of various enterprises.

2、Structural shape and size: large steel plate silo is a large thin-walled container, the height to diameter ratio is generally about 1:1. The silo body is cylindrical and the silo roof is spherical. The wall of the silo is welded with steel plate (lap welding); the semi-circular spherical shape of the silo roof is formed by the structural design of steel sections and the combination of multiple arch beams to form a unique structural building. Its dome has reliable bearing capacity.

3、Feeding mode: The feeding and conveying mode can be pneumatic conveying by pipeline or mechanical conveying according to Party A's requirements. Feeding method adopts center point feeding at the top of the silo.

 

4、Steel plate silo unloading principle and description: unloading corridor according to the diameter of the silo to determine. When the material is full of steel plate silo, according to the need to open the part of the valve, which part of the need to start unloading, so that the material in the air force and gravity under the dual role of smooth flow.

5, gravity unloading and pneumatic unloading combined unloading method: material pressure is evenly distributed on the steel plate silo floor, through the silo floor will be the pressure to the ground, to realize the preload bearing, can meet different requirements. The foundation has strong bearing capacity, and the silo bottom plate is filled with lightweight pressure-resistant material; the conveying adopts pneumatic conveying to realize the dense-phase or dilute-phase unloading of materials. The capacity of conveying materials can be realized by adjusting the grating wheel with frequency conversion speed regulator under the silo. The whole system can realize local automatic and centralized control. The technology utilizes the technical characteristics of the dual combination of gravity discharge, pneumatic discharge and conveying. In the case of non-aerated, the material with high material level is conveyed by gravity discharge. When the material level is low, the material is loosened from the outlet through the fluidization device, and then the material is conveyed through gravity discharge, which greatly saves energy and reduces power consumption.

6、Smooth operation, easy to automate: unloading is uniform and stable, and there will be no walking, running off, cross phenomenon. Ensure the safety of the steel plate warehouse, easy to automatic and orderly control. Automatic control cabinet has local manual control, local automatic control and computerized centralized control.

7、Low gas consumption: As the silo adopts the design concept of gas fluidization unloading, gas homogenization and gas conveying integration, i.e. the principle of one gas multi-purpose, it can save a lot of gas source.

8, the quality of material storage impact: with the extension of the storage period, the volume weight of the material increases. The material is basically vacuum sealed in a large steel plate warehouse in the tight air isolation. The sealing effect is much better than brick, stone and concrete structure silo, which is incomparable to bagged materials.

9. Environmental compliance: the top of the Storage Silo is a load-bearing dome, and the top of each silo is equipped with a pulse-knocking dust collector, which mainly collects the dust generated when the material enters the silo.

10. Process arrangement: It can be flexibly arranged according to the site location, and the direction of the unloading gallery can be flexibly determined according to the site conditions. As the unloading adopts pneumatic pipeline, the position of silo elevator can be chosen freely.

11. Short construction period: according to the geological conditions, construction site and construction environment, the construction period is short. In case of silo group construction, cross construction or simultaneous construction can be adopted to shorten the construction period.

12. Long service life: the unique combination interface makes the Steel Silo safer. The structure is equivalent to the frame structure of the building, with strong anti-seismic, anti-deformation and repository bearing capacity.

13. Low maintenance cost: the gasification, unloading and conveying equipment in the steel silo is basically maintenance-free, with no running parts.

14. Safe maintenance: convenient and safe maintenance, lifting the user's worries. No need to clean up the steel silo, you can easily maintain the fluidized rod in the steel silo.
