Circular stockyard

Abstract

The invention belongs to the field of storage and conveying facilities of bulk materials and relates to a circular stockyard. The circular stockyard comprises a sealed storage shed, a material feeding and piling system, a material taking and discharging system, storage cells, radial retaining walls and an annular retaining wall, wherein the inner side of the annular retaining wall forms the storage bin in an enclosed manner, and the outer side of the annular retaining wall and the radial retaining walls form the storage cells in an enclosed manner; a first annular rail is arranged on the annular retaining wall, a second annular rail is arranged at the outer edges of the radial retaining walls, a storage cell material taking frame is arranged on a gantry type frame between the first annular rail and the second annular rail, and the radial retaining walls and the annular retaining wall support each other. The circular stockyard has the advantages that the annular retaining wall structure has good space force transmission performance, a load bearing structure high in bearing capacity and large in rigidity can be formed by a small structural thickness, the stockyard structure can evidently reduce the length and thickness of the retaining walls, civil engineering cost is low, and the circular stockyard has extremely high engineering application value.

Description

technical field [0001] The invention belongs to the field of storage and conveying facilities for bulk materials, and relates to a circular material yard. Background technique [0002] At present, the open-air stockyard has been widely used in power plants, building materials, mines, ports, metallurgy, grain and other industries at home and abroad. It is the main storage method for bulk materials. It has many engineering application examples, flexible process layout, and mature process technology. The reliability of the process equipment is high, and the civil engineering and other public and auxiliary facilities are mature. However, this open-air storage method also faces problems such as environmental pollution, material loss, low utilization of storage space, large floor space, and long transmission lines. , especially for bulk materials that require special requirements such as moisture-proof, rain-proof, wind-proof, cold-proof, and freeze-proof, it is difficult for the ...

AI Technical Summary

Problems solved by technology

The storage yard has many advantages in terms of closed space utilization, material variety adaptability, and floor area, but there are also some shortcomings. The main manifestations are: at least two roads must be installed vertically on both sides of the storage bin to run through the entire site. , the vertical wall of the same thickness, for the occasions with large material volume and high storage height, the thickness of the vertical wall will be very thick, and the civil construction cost will rise sharply; at least two sets of reclaimers and material Conveyors, feed conveyors and stackers require a large investment in equipment costs
