Environment-friendly dust suppression material shed with semi-closed framework membrane structure

Abstract

The invention discloses an environment-friendly dust suppression material shed with a semi-closed framework membrane structure. The environment-friendly dust suppression material shed comprises a steel framework, a membrane, a breathable windproof cover and foundation bases, wherein the steel framework comprises a plurality of annular trusses which are arranged in parallel in a spacing manner and longitudinal trusses which are erected on the cambered surfaces of all the annular trusses in parallel in a spacing manner, the two ends of the annular trusses are fixed to the foundation bases, and the annular trusses at the front end and the rear end are blocked from the ground; a top frame is arranged between the pair of longitudinal trusses at the highest position of the steel framework, and the breathable windproof cover is arranged in the top frame; and the membrane is attached and fixed on the steel framework in an area below the height of the top frame, and the bottom side of the membrane is sealed on the foundation bases. The material shed has the beneficial effects that the air speed in the material shed is reduced, and the range of internal dust raising is reduced; the breathable windproof cover can enable internal gas to communicate with external atmosphere, so that the fireproof and explosion-proof problems of a closed warehouse can be solved; and a spray dust suppression facility is adopted to prevent raising dust from diffusing and overflowing, so that the material shed is in a closed state for dust.

Description

technical field [0001] The invention relates to the field of environmental protection storage structure design, in particular to a semi-enclosed skeleton membrane structure environmental protection dust suppression material shed. Background technique [0002] The terminal bulk material storage yard is easy to generate dust with the wind and spread with the atmosphere, causing serious pollution to the environment around the port storage yard. As the country pays more and more attention to environmental protection and ecology, the newly-built wharves are equipped with windproof and dust-suppressing nets or closed storage sheds to suppress dust pollution. [0003] Compared with the windproof and dust suppression net, although the one-time construction cost of the closed material shed is higher, the later transportation and management cost is lower. The initial cost of the windproof and dust suppression net facilities is relatively low, but the large amount of sewage discharge ...

AI Technical Summary

Problems solved by technology

However, the closed material shed will be restricted by the fire protection zone of the building, and the maximum construction area of ​​a single unit shall not exceed 12,000m2 2 , which is limited in large-area application; the explosion-proof design of the closed silo will also lead to an overly complex structure of the silo, increasing the difficulty of construction and increasing the construction cost; at the same time, the structural column spacing is relatively dense, which can only meet one-way operations. Great impact on production efficiency
