Embodiment

[0026] A dust control device for the mine boundary disclosed by the present utility model is in the scenario of automatic spray dust suppression.

[0027] Refer to Figure 1 , a dust control device for the mine boundary, includes an automatic control terminal 1, a plurality of fog cannon machines 2 and a water source aggregation device 3; the automatic control terminal 1 is connected to the fog cannon machine 2 through an electric wire, and the fog cannon machine 2 is connected to the water source aggregation device 3 through a pipeline, and the pipeline usually adopts pressure-resistant and corrosion-resistant materials such as PVC, PE, stainless steel, etc. As Figure 2 shown, the automatic control terminal 1 includes a concentration intelligent early warning module 11 and a dust suppression control module 12. Specifically, the automatic control terminal 1 is an automatic control host with a concentration intelligent early warning module 11 and a dust suppression control module 12.

[0028] As Figure 2As shown in the figure, the intelligent concentration warning module 11 includes: a dust monitor 111, a real-time concentration warning unit 112, and an information sending unit 113; a dust suppression control module 12 is provided with a timing switch 121. For the convenience of dust monitoring, the specific dust monitor 111 is installed on the top of the automatic control terminal 1.

[0029] The dust monitor 111 is connected to the real-time concentration warning unit 112 through a data line that meets the RS485 protocol. The real-time concentration warning unit 112 and the information sending unit 113 are integrated inside the automatic control host and are connected through the internal bus I2C. The information sending unit 113 is connected to the dust suppression control module 12 through the internal bus I2C.

[0030] The dust monitor 111 provides real-time dust concentration data to the real-time concentration warning unit 112; the real-time concentration warning unit 112 compares the dust concentration data provided by the dust monitor 111 with a preset threshold and transmits the result exceeding the threshold to the information sending unit 113; the information sending unit 113 transmits the signal exceeding the threshold to the dust suppression control module 12.

[0031] Specifically, the dust monitor 111 mainly monitors three indicators. The preset threshold for PM2.5 (24-hour average value) is 35 ug / m3, the preset threshold for PM10 (24-hour average value) is 75 ug / m3, and the preset threshold for TSP (24-hour average value) is 150 ug / m3. If any one of them exceeds the warning value, the information sending unit 113 will transmit the signal exceeding the threshold to the dust suppression control module 12.

[0032] The output end of the timing switch 121 is electrically connected to the fog cannon 2. When the dust suppression control module 12 receives the alarm information, it activates the timing switch 121. The timing switch 121 is turned on, and the fog cannon 2 starts to spray automatically. When the preset time is reached, the timing switch 121 is turned off, and the fog cannon 2 is turned off, thereby realizing the control of the fog cannon 2 to be turned on and off regularly according to the alarm information provided by the intelligent concentration warning module 11. Realize the automatic control of the start of the fog cannon 2 group, thereby quickly reducing the dust concentration, being able to perform targeted dust suppression, and effectively improving the dust suppression effect. Figure 2 As shown in the figure, in order to ensure the maximum coverage range and enhance the effect of suppressing dust, the fog cannon 2 is selected as a model with a rotating seat 21 provided at the bottom of the gun barrel, which can automatically rotate reciprocally by 180° and has a spraying range of 50 - 60 meters to form a "plane-shaped water curtain wall". In order to form a continuous dust suppression belt, the fog cannons 2 are arranged along the mine boundary at an interval of 50 meters.

[0033] As Figure 3As shown in the figure, in order to improve the utilization rate of water resources, a water source aggregation device 3 is also provided, which includes an intercepting and draining ditch 31, a trash rack 32, a grit chamber 33, and a water storage tank 34. Each section of the intercepting and draining ditch 31 is connected end to end to form a ring. The intercepting and draining ditch 31 surrounds the mineral mining area and is connected to a number of water storage tanks 34. A trash rack 32 and a grit chamber 33 are successively arranged between the water storage tank 34 and the drainage ditch. The aggregated water source can be treated by the trash rack 32 and the grit chamber 33, which can meet the use of the fog cannon machine 2. Using rainwater and treated wastewater as the dust suppression water source not only reduces the dependence on groundwater and tap water, but also realizes the recycling of water resources, saves precious water resources, and reduces the operating cost at the same time.

[0034] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution can be the substitution of part of the structure, device, and method steps, or the substitution of the complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
