Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing raw materials in an outdoor yard from generating dust due to wind force.

In the raw material yard, in order to prevent the raw materials 1 piled up as shown in FIG. 1 from generating dust due to the wind 10, the raw materials 1 were sprinkled with water or dust-proofing agents were sprayed. However, these conventional methods are uneconomical because they are spraying methods, and they do not provide sufficient measures to prevent dust generation.

An object of the present invention is to reduce the dust-generating force exerted on the raw material, essentially eliminating the dust-generating force and obtaining a sufficient dust-proofing effect.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 5.

As shown in Figure 2, the raw material powder 2 is
It is surrounded by side walls 3a and 3b having side walls 3a and 4b. 6a, 6b are net-like objects 6a, 6b with appropriate rigidity attached on the side walls 3a, 3b.
It is provided at an appropriate distance a from the inner side of the side walls 3a and 3b. With a structure like this,
The wind 10 is blocked by the side wall 3a, and is restrained by the eaves 4a so that it does not flow upward, but flows backwards as shown by reference numeral 11, making it possible to weaken the vortex wind force generated on the powder and granular material 2 than in the case where there is no eaves. . Further, the wind 10 passing through the net-like object 6a is significantly decelerated and flows over the powder material 2. In addition, since a backflow as shown by reference numeral 12 may occur in the lower part of the rear net-like object 6b, the net-like object 6b is placed at a position a suitable distance a from the inside of the side wall 3b so that the influence is not exerted on the granular material 2 as much as possible. It is good to have one. In a raw material yard having this structure that combines the above-mentioned effects, dust generation from powder particles can be significantly reduced.

The raw material yard shown in Figure 2 is the same in both front and back, and is suitable for locations where the wind direction is not constant. In places where the wind direction is almost constant, use the method shown in Figure 3 or 4 to further prevent dust that cannot be completely prevented and scattered.
As shown in the figure, net-like members 7 and 8 are preferably provided upright on the outside of the leeward side wall 5. That is, the windward side wall 3a is provided with an eaves 4a and a net-like member 6a, and the leeward-side side wall 5 is not provided with an eaves or a net-like object, but instead a net-like object 7 is installed at a position slightly away from the side wall 5 from the ground. Alternatively, a reticulated object 8 may be provided above the barrier 9 above the ground. In this way, most of the scattered dust 14a, 14b accumulates in this part due to the backflow 13a, 13b generated in this part. Particularly in the case of the structure shown in FIG. 4, the amount of particles scattered outside the barrier is significantly reduced by the barrier 9.

FIG. 5 shows an example of application in which there are a plurality of yards, which is economical since no eaves or net-like objects are required for each yard. Such a method can significantly reduce the scattering of powder and granules from the yard.

The present invention significantly reduces the wind speed passing over the powder and granular material that generates dust, thereby reducing the amount of dust generated, and has a great effect on dust prevention.
