Description

Technical Field

[0001] The utility model belongs to the field of dust prevention equipment, in particular to an automatic dust suppression device for open-air mineral powder storage. Background Art

[0002] At present, most of the mineral powder in open-air storage yards is reduced and suppressed by using wind-proof dust-suppression nets, spraying dust suppressants, installing dust-suppression fog cannons or dust-suppression vehicles. However, the large-scale installation of wind-proof dust-suppression nets is expensive and easily restricted by terrain; the regular spraying of dust suppressants is time-consuming and labor-intensive; dust-suppression fog cannons and dust-suppression vehicles require manual control and cannot achieve all-weather automatic dust suppression. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic dust suppression device for open-air mineral powder storage, so as to make up for the problems of high construction cost and poor automation of existing open-air storage yard dust suppression methods.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] An automatic dust suppression device for open-pit mineral powder storage includes a water tank, an anemometer and a control module are provided at the upper end of the water tank, a water outlet pipe is provided at the lower end of the water tank, a solenoid valve and a booster pump are provided in sequence on the water outlet pipe, the rear end of the booster pump is connected to a high-pressure water spray pipe, and a plurality of pneumatic spray heads are distributed on the high-pressure water spray pipe.

[0006] Furthermore, a filter is provided at the water outlet pipe in the water tank.

[0007] Furthermore, the pneumatic sprinkler head includes fan blades, an inner tube and an outer tube, and water spray holes are provided on both the inner tube and the outer tube.

[0008] Furthermore, the inner tube is connected to the high-pressure water spray pipe, and the outer tube is connected to the fan blades.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0010] This device can set the wind trigger threshold in advance and spray water mist above the ore pile before the natural wind reaches the dust limit to achieve the purpose of dust suppression. This device does not require human supervision, has a high degree of automation, is low in cost and is reusable. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, an embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention in detail.

[0017] Example 1

[0018] like Figures 1-4 As shown, an automatic dust suppression device for open-pit mineral powder storage includes a water tank 1, the size of which can be changed according to usage. An anemometer 2 and a control module 3 are provided at the upper end of the water tank 1. The anemometer 2 monitors natural wind force. When the wind force reaches a preset value (the preset value can be changed according to the type of mineral powder), the solenoid valve 5 of the water outlet pipe 4 at the lower end of the water tank 1 is opened, and the booster pump 6 is connected at the same time. The booster pump 6 boosts the water entering the high-pressure water spray pipe 7. A plurality of pneumatic spray heads 8 are distributed on the high-pressure water spray pipe 7. A plurality of water spray holes 84 are distributed on the inner tube 82 and the outer tube 83 of the pneumatic spray head 8. Natural wind blows the fan blades 81, thereby driving the outer tube 83 to rotate. When the water spray holes 84 on the inner tube 82 correspond to the water spray holes 84 on the outer tube 83, the water in the high-pressure water spray pipe 7 is immediately sprayed out. By setting the appropriate position of the water spray holes 84, the faster the wind speed, the faster the water spraying speed. When the natural wind speed is less than the preset value, the control module 3 closes the electromagnetic valve 5 and the booster pump 6, and the water spraying stops.

[0019] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to modification and variation. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
