Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1-2, the present invention provides a prestressed truss structure fully-enclosed coal shed,
the coal shed comprises a coal shed main body, the coal shed main body comprises a cover shell 1 with an arch structure, the two ends of the cover shell 1 are provided with arch openings, the front end and the rear end of the cover shell are provided with gable walls 2 with the arch structures in a matched mode, so that the cover shell 1 and the gable walls 2 enclose a closed space for storing coal, the gable walls 2 are arranged to be truss structures, the gable walls 2 comprise a plurality of lattice columns which are perpendicular to each other and connected, the gable walls 2 are of grid structures and comprise a plurality of steel rods which are connected with each other, the outer edges of the gable walls 2 are welded with the inner wall of the cover shell 1, the inner side wall of the upper end of the cover shell 1 is provided with a plurality of water inlet pipes 3, the water inlet pipes 3 are arranged in a fit with the inner side wall of the cover shell 1, the water inlet pipes 3 are arranged at uniform intervals, a plurality of the water inlet pipes 3 are communicated with nozzles 4, and the nozzles 4 are arranged to be atomizing nozzles, the side wall of the cover shell 1 is provided with an air blower 5, an air outlet of the air blower 5 is communicated with a settling device 6, the settling device 6 can collect and settle dust in the coal shed main body into solid, the settling device 6 is a coarse powder separator,
the coal shed main body is of a fully-closed structure, so that a coal yard can be completely shielded, and compared with a semi-closed coal shed and an unsealed coal shed in the prior art, the coal shed main body can prevent coal dust in the coal shed from leaking to the maximum extent to cause environmental pollution, so that the fully-closed coal shed main body has a good environment-friendly effect;
