Abstract

PURPOSE:To prevent coal dust from flying-up and scattering by erecting a gauge fence on the top of a partition wall in an outdoor coal stocking equipment to eliminate spiral flow produced by wind on the upper surface of a coaling station. CONSTITUTION:When wind blows in the direction of arrow P, a portion of this wind passes through one gauge 13 to flow over the upper portion the interior of a partition wall 11 in the direction of arrow Q so that a spiral flow is produced at the rear side of the partition wall 11 as shown by arrow R. Since the partition wall 11 is provided on the top with the gauge 13 the flow speed of wind is decelerated when the wind passes through the gauge 13, for example the flow speed is aproximately halved when the mesh of the gauge 13 is made about 5mm.. Thus, the flow speed of the spiral flow in the direction of arrow R becomes very slow to reduce substantially flying-up of coal dust. Also, even if the coal dust flies up due to the spiral flow to ride on wind in the direction of arrow Q, since this wind passes through the other gauge 13 to flow to the outside of the partition wall 11, the gauge 13 provides a kind of filter to block the passage of coal dust.

Description

[Detailed description of the invention] The present invention relates to an outdoor coal storage device.

As a conventional oak coal storage device, as shown in FIG. 1, one is known in which a coal storage area (2) -dll is constructed around the area (2) Nl.

However, in a conventional outdoor coal storage device like this, when the wind blows as shown by arrow A, when this wind passes through the upper end of w & sol, it is accelerated and 0
Than! Negative pressure is generated on the back side of Ia Sanl, and then Sister lr
A swirling flow of 5 to 6 times the height of the horizontal distance shown by the butterfly arrow C on the back side of D occurs, and this swirling flow raises coal dust. In order to avoid such problems, conventional methods have been used to spray water on coal while it is being stored. Treatments such as curing and spraying a surface coating agent are carried out, but the work is troublesome and the storage cost increases considerably.In addition, other conventional coal storage devices Although it is possible to install a roof and make it an indoor type, this has the disadvantage of requiring a long construction period and significantly increasing construction costs.

The present inventor has developed an outdoor coal storage system in view of the above circumstances, which can effectively prevent the scattering of coal without any special treatment, and can be constructed in a short period of time and at low construction costs. The purpose is to provide it to W1.

Hereinafter, one embodiment of the present invention will be explained with reference to FIGS.
Coal 18 can be stored in the area surrounded by. At the upper part of the retainer 1111, 12 heather supports 12 are erected at intervals in the longitudinal direction. Between the pillars 12 there is a company wire mesh (
A mesh-like fence) 18 has been erected.

Note that %14 is rail 1 laid in the center of 5m1t.
This stacker reclaimer is made to run on 5-stars with a poor stacker reclaimer! -14 and belt conveyors 16, 17, etc. are used to carry coal into the holding 1ull or conversely to carry it out of the holding 1!11. Next, the outdoor coal storage system with the above configuration @V #
Figure 4A about @? Refer to and explain. If a locust blows as shown by arrow P, a part of this vK will fall on one side of the wire mesh 18.
It passes through the upper part of the retaining wall 11 as shown by the arrow Q and flows towards the bottom 2, and on the back side of the retaining wall 11, a swirling flow as shown by the arrow R occurs.By the way, the upper end of the retaining wall *11 Since a wire mesh 18 is provided in the section, the flow velocity is reduced when one wire passes through the wire mesh 1B, and for example, if the wire mesh 1B has a mesh size of about 5111E, the rIL chain will be approximately halved.

Therefore, the flow velocity of the swirling flow indicated by arrow R is much smaller than that of the conventional flow. Therefore, the amount of coal dust thrown up by this swirling flow is significantly reduced. Furthermore, even if coal dust is kicked up by the swirling flow and rides the slope shown by the arrow Q, the lice pass through the other wire mesh 18 and flow out of the bowl Wtt, so the wire mesh 1B acts as a kind of filter. None - this prevents the passage of coal dust here. Note that even if the coal dust passes through the other wire mesh 18Yr, the lice passing through the other wire mesh 18 are further decelerated here, so the coal dust will not be scattered far.

Here, the outdoor coal storage device line having the above structure has an extremely simple structure in which the supports 12 are provided on the top of the retaining area 111 and the wire mesh 1B is stretched between the supports 12, so it can be constructed in a short period of time and at low construction cost. be able to.

As explained above, according to the outdoor coal storage device of the present invention, since the mesh-like fence is erected on the retaining wall, the number of squares of coal dust can be reduced without the need for special treatment as in the past. Therefore, it is possible to reduce the accumulated 11 tp stress to a large extent, and the structure is simple and can be constructed in a short period of time and at low construction cost.
