[0007] The surrounding wall is a concrete cast-in-place integrated structure.

[0008] The windbreak net is uniformly provided with a plurality of ventilation holes, and the hole diameter of the ventilation hole is 0.2-1.0 mm.

[0009] The windbreak net can be fixedly installed as a U-shaped, W-shaped, S-shaped or V-shaped structure on the structure column.

[0010] The surface of the windbreak net is provided with a rust-proof and corrosion-resistant treatment layer.

[0011] The two sides of the rain shed are connected with the structure column by a plurality of support columns, and the support column is fixedly installed at the top end of the structure column.

[0012] The water curtain spray head is connected with the booster water pump in the water storage pool through a pipeline.

[0013] The water collecting pipe is communicated with the water collecting pipe at the bottom end of the water collecting pipe.

[0014] The water outlet of the water curtain spray head corresponds to the water collecting pipe, and the spray pressure of the water curtain spray head is 0.2-0.5 MPa.

[0015] In summary, due to the adoption of the above technical scheme, the beneficial effects of the utility model are:

[0016] 1) The particle diameter of the water sprayed by the water curtain spray head is 1-10 μm, which is allowed to settle under the action of its own gravity to form a water curtain wall, so that the dust suppression effect can reach more than 85%-95%;

[0017] 2) The utility model utilizes the principle of aerodynamics to process the wind-shielding and dust-suppressing wall into different geometric shapes according to the environment of the implementation site, so that when the circulating air (strong wind) passes through the wall body from the outside, the airflow on the inside of the wall body is interfered from top to bottom to achieve the effect of strong wind on the outside, weak wind on the inside, small wind on the outside and no wind on the inside, thereby preventing the flying of dust and realizing the saving of raw materials and the protection of the environment;

[0018] 3) The water spraying dust suppression design of the utility model utilizes the principle of the fine water curtain wall, the water mist dispersed in the air generates negative ions, which combine with a large number of positive ions in the dust, when the particle diameter of the mist droplet and the dust particle is similar, the mist droplet and the dust particle will be mutually adsorbed and adhered, and after the weight is increased, the mist droplet and the dust particle will settle, so that the dust diffusion is effectively suppressed, and the dust reduction is achieved;

[0019] 4) The utility model adopts the combined design of the windproof net and the water curtain wall device, which effectively prevents the dust generated in the loading and unloading of the mine powder yard and the mixing process and the screening process, solves the problems of serious environmental pollution and mine powder loss, and effectively protects the environment.
