Abstract

PURPOSE:To enable reliable sprinkling on a pile of a bulk material in a sprinkler device for an outdoor storage yard by making the sprinkling range from a sprinkling force on a head wind side longer and making the sprinkling range from the sprinkling port on a tail wind side correspondingly shorter. CONSTITUTION:Sprinkling nozzles 2, 2a are provided on both sides of a coal storage pile 1, and the value measured with a wind vane and anemometer 3 is inputted to a control device 4. Control valves 5, 5a are operated by the signal of the device 4 to adjust the sprinkling pressure or rate of the nozzles 2, 2a. The adjustment is accomplished by operating the valves 5, 5a reverse to each other to change the sprinkling tracks 6, 7 from the nozzles 2, 2a of the case when there is no wind 10 in such a way that the sprinkling track from the nozzle 2 on the head wind side is made short and the sprinkling track from the nozzle 2a on the tail wind side is made long thereby changing the sprinkling pressure. The angle for sprinkling is further adjusted according to need. Actual sprinkling ranges 6a, 7a are thus maintained constant and always the desired sprinkling state is maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] This invention relates to the construction of uninvented let Bn storage yards (+IR).

[Prior art]

Coal and other loose materials are piled up in outdoor storage yards, and in order to prevent the coal from igniting and generating dust, there are
Add water to the pile from the water spout (°C 1,). As a condition to add watering, windmill, El, f! i', fluorine was added in the okikata. However, if the conditions were satisfied, simply sprinkling water would not be practical because the water would not reach the destination due to the wind, or the water would travel too far from the destination due to the wind. .

[Purpose of the invention]

An uninvented purpose (well, to ensure that water is applied to piles of loose materials in outdoor storage yards).

[Summary of the invention]

In equipment that has water sprinkling ports facing the mountain side around a small pile of drumsticks in an outdoor storage yard,
This is a water sprinkling control method characterized by correcting the water sprinkling conditions so that the water spray from the spout is in the opposite condition, and is proportional to the wind speed. This is done so that the flying distances of water from a headwind and from a tailwind do not vary too much.

[Embodiments of the invention]

Hereinafter, one embodiment of the invention will be described with reference to FIGS. 1 to 5.

FIG. 1 is a conceptual diagram of an uninvented automatic watering equipment, in which watering nozzles 2, 2a are provided on both sides of a coal storage pile 1. Further, a wind direction/anemometer 3 is provided on the side of the coal storage pile, and the measured values are sent to a control device 4.

Water nozzle 2\1← and 2a each have a control valve 5゜5.
3 is provided, and the water spray pressure and, depending on the case, the water spray amount are also adjusted based on instructions from the control device 4. Further, the water spraying angle of each of the water spray nozzles 2 + 2 alet can be independently changed based on commands from the control devices 4).

FIG. 2I shows an example of the water sprinkling trajectory from the water sprinkling nozzle 2, and shows a case where there is a tailwind. Here, the dashed line 6 it style 10
The solid line 6a shows the trajectory when there is no wind, and the trajectory contains water when there is wind. Similarly, FIG. 3 shows an example of the sprinkling trajectory of the sprinkling nozzle 2a in the case of a headwind; the dashed line 7 shows the trajectory when there is no wind, and the solid line 7a shows the trajectory when there is a wind 10.

Fig. 4 and Fig. 5 i'i Under exactly the same conditions as Fig. 2 and Fig. 3, Fig. 4 shows a water spray pressure of about 0.5 Kjil.
Lower f/crI, and on the contrary, Fig. 5 shows approximately 0.5 K9 f
/d shows the case where the dashed line 8.9 is when there is no wind 10.

Solid lines 8a and 9a indicate the case where there is wind, and the solid lines ffR8a and 9al:? The scattering distance is exactly the same as that of set trajectories 6 and 7.

That is, in this example, it is approximately 05Ky.
Reduce r/cd watering pressure, against headwind/approximately 05
Kl f 7'crJ By decreasing the water spray pressure by -F, the influence of wind can be corrected.

In addition, in this example, each watering condition, that is, pressure and watering angle,
Although we changed the watering pressure, the effects of wind can also be compensated for by changing the watering angle.

Furthermore, it is also possible to adjust both the water spraying pressure and the watering angle, and it is also possible to adjust the watering amount as necessary.

Wind direction/anemometer 3 to measure the wind direction and speed that change from moment to moment.
The information is sent to the control device @4, where it is calculated and a command is sent to the water sprinkling control valves 5 and 5a to adjust the water sprinkling pressure.

Further, if necessary, a command is sent to the water spray nozzles 2, 2a to adjust the water spray angle.

With such an automatic control method, watering can always be automatically performed as close to the set state as possible.

In this example, the force used to control the water spray pressure using the control valves 5 and 5a ≦
1. [Effects of the Invention] According to the present invention, it is possible to control the water spray distance without being affected by the wind. H% power can be maintained constant, so constant ÷
This has the effect of providing a state of water sprinkling in a state of deafness.
