Closed stockyard

Abstract

The invention discloses a closed stockyard. The closed stockyard comprises an annular wall, a conical dome (1) connected with the top of the annular wall, a center column (6) arranged in the center of the annular wall, a material input system and a material output system; the material input system comprises a trestle (8) connected with the center column (6), a feeding belt conveyor (11) arranged in the trestle (8), and a stacking device (7) connected with the center column (6); and the material output system comprises a half-door scraper taking machine (3), a first annular rail (24) and a second annular rail (17) arranged on the inner side of the annular wall, an annular conveyor (2) connected with the first annular rail (24) and the second annular rail (17) and bearing incoming materials from the half-door scraper taking machine (3), a discharge belt conveyor (12) for bearing the incoming materials from the annular conveyor (2), and a plough unloader (9) for shoveling off the materials in the annular conveyor (2) onto the discharge belt conveyor (12).

Description

technical field [0001] The invention relates to the technical field of storage and transportation of bulk materials, in particular to a closed stockyard. Background technique [0002] The fully enclosed circular stockyard has been widely used in industries such as coal, grain, building materials, chemical industry, electric power and metallurgy due to its good environmental protection, land saving, beautification of the environment, and stable production. [0003] CN205771355U disclosed a novel closed material yard on December 07, 2016. The closed material yard includes a material input system, a material output system, a central support structure, a material storage yard, and a closed material storage shed. The material input system includes a stack The stocking device, the upper running platform of the stacking device on the middle support structure, the lower running platform of the stocking device on one side of the closed storage shed, the stacking device is equipped wi...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the fully enclosed circular stockyard has the following disadvantages: in order to provide stockyard reserves, it is necessary to set up a high retaining wall; since the center of the stockyard discharges the material, the equipment is in the center of the circular stockyard, and it is necessary to place the discharge The material belt conveyor is arranged in the underground corridor to transfer the material from the center of the material yard, causing the underground corridor to sink to a deeper underground position; once the material yard is built, it cannot be expanded; a single material yard can only store a single quality materials, it is impossible to pre-mix the materials; the huge amount of civil works and the complicated equipment lead to large investment in the stockyard, long construction period, and greatly reduce the adaptability and optionality of the stockyard
