Problems solved by technology

The seepage flow still produces a large amount of dust
[0007] In addition, the angle of the traditional windproof and dust suppression net cannot be adjusted properly with the change of wind direction, and the dust suppression effect is further limited

Embodiment 1

[0026] Example 1. The invention discloses a windproof and dust-suppressing method for an open-air bulk material storage yard. Include the following steps:

[0027] (1) Build concrete foundations around the open-air bulk material storage yard;

[0028] (2) Fix and support the steel structure on the concrete foundation;

[0029] (3) Install wind-proof and dust-suppressing mesh panels on the supporting steel structure;

[0030] (4) The installed wind-proof and dust-suppressing nets have two structures: wind-shielding nets and dust-blocking nets. The wind-shielding nets are set on the mainstream wind surface, mainly to reduce the wind intensity, and the dust-blocking nets are set on other secondary wind surfaces. , which mainly intercepts the escape of dust particles raised by the mainstream wind. When the wind direction changes so that the dust blocking device is in the mainstream wind direction, the dust blocking device will play a role in reducing the wind strength, and othe...

Embodiment 2

[0040]Example 2. A windproof and dust suppression net, such as Figure 1 ~ Figure 2 shown. It includes the concrete foundation fixed around the open-air bulk material pile, the supporting steel structure 2 fixed on the concrete foundation, and the web installed on the supporting steel structure 2. Shafts 1 are fixed on the left and right sides of the middle 3 rows of windshield valves 3 arranged on the mainstream wind surface, and two left and right bearings 4 are fixed on the corresponding positions on both sides of the supporting steel structure 2, and the shaft 1 is installed on the left and right bearings 4 middle. The driven sprocket 5 is also fixedly installed on the shaft 1. A motor 6 is fixedly installed on the supporting steel structure 2 , and a drive sprocket 7 is fixedly installed on the shaft of the motor 6 . Drive chain 8 is installed on driving sprocket 7 and driven sprocket 5. The mesh 9 on its web 3 is a long hole, and one side of the mesh 9 is stamped in...

Abstract

The invention relates to a wind and dust resisting method for an open stacking site of bulk materials, a wind and dust resisting net and the application thereof. The method comprises the following steps: a concrete base is built around the material stacking site; a support steel structure is fixed on the concrete base; the support steel structure is provided with net leaves of the wind and dust resisting net; a main flow wind surface is provided with wind resisting net leaves, and other secondary flow wind surfaces are provided with dust resisting net leaves; the height at which the net leaves are arranged is more than the stacking height of the material stack; the opening ratio of the net leaves is 20 percent to 50 percent and the like. 1 to 3 rows of wind resisting net leaves in the middle of the main flow wind surface are provided with a turnover mechanism. Net holes are long holes or elliptic holes, one side of the net hole is punched into a flanging guide fin which has a certain angle and has guide function. The boundary layer separation, the vortex and the permeation flow are eliminated or reduced effectively, the angle of the dust resisting net can be regulated according to wind directions; and the effect of resisting dust, especially secondary blowing dust can be improved greatly. The invention can be widely applied to the open stacking site of bulk materials in ports, coal mines, coal fired power plants, etc.

Description

technical field [0001] The invention belongs to the technical field of windproof and dust suppression, and more specifically relates to the improvement and innovation of a windproof and dust suppression method for an open-air bulk material storage yard, a windproof and dust suppression net and its application. Background technique [0002] Enterprises such as ports, coal mines, iron and steel plants, coal-fired power plants, lime and cement material plants all have open-air bulk material storage yards. Under the action of wind, dust and secondary dust will inevitably be generated. The solid particles stored in the open air mainly have three kinds of motion states under the action of wind force: the ones that roll along the ground are called spiral motion; the ones that are carried by the wind and migrate with the wind are called suspension; the particles between spiral motion and suspension are first Jumping into the air and then falling back to the ground along a regular t...
