[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and does not constitute any limitation on the present invention and its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments herein. In the present invention, when a specific device is described as being between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device.

[0031] like Figures 1 to 6 As shown, the utility model provides an embodiment of a mine spray dust reduction system with a high-efficiency dust reduction function, wherein a support arm 13 is connected to a support base 11 and extends outward in a horizontal direction, and relatively outwardly extending planar frames are arranged on both sides of the support arm 13, wherein the planar frames are planar frame structures, and an air passage is arranged between the atomizing nozzle 31 and the dust suction nozzle 41.

[0032] The atomizing nozzles 31 are arranged in an array on the bottom surface of the planar frame, and the atomizing nozzles 31 are connected to the water tank 34 through a high-pressure water supply mechanism. The dust suction nozzles 41 are arranged in an array on the top surface of the planar frame, and the dust suction nozzles 41 are connected to the air filtering mechanism 44 through a negative pressure dust suction mechanism, and the central controller 51 is controlled and connected with the high-pressure water supply mechanism and the negative pressure dust suction mechanism. The central controller 51 can be an industrial computer, a PLC programmable controller, or an intelligent control device. During implementation, the central controller is connected to a command input port and a remote control handle to facilitate the work control of the system.

[0033] The working principle of this mine spray dust suppression system with high dust suppression function:

[0034] The high-pressure water supply mechanism sprays water mist through the atomizing nozzle to humidify the dust in the air below the flat plate frame and make the dust fall to the ground. The negative pressure dust suction mechanism absorbs the dust in the air above the flat plate frame through the negative pressure of the dust suction nozzle and collects it through the air filtration mechanism. The negative pressure suction makes the dust above float to the flat plate frame and reduces the dust flying around.

[0035] Spray dust suppression and negative pressure dust collection work simultaneously, combined with the flat plate frame to achieve large-area operation characteristics, which can effectively increase the dust removal speed, improve the working air quality, and improve working safety.

[0036] The high-pressure water supply mechanism includes a high-pressure water pump 32 , which is connected to each atomizing nozzle 31 via a water flow regulating valve 33 , and the central controller 51 is control-connected to the water flow regulating valve 33 .

[0037] The negative pressure dust suction mechanism includes a negative pressure air pump 42 , which is connected to each dust suction nozzle 41 via an air flow regulating valve 43 , and the central controller 51 is controllably connected to the air flow regulating valve 43 .

[0038] The mine spray dust suppression system is also provided with a dust concentration monitor 52, and the central controller 51 is connected to the dust concentration monitor 52 by signal. The central controller 51 controls the water supply speed of the high-pressure water supply mechanism and the dust suction speed of the negative pressure dust suction mechanism according to the received dust concentration monitoring information. Specifically, when the dust concentration is high, the water supply speed and the dust suction speed are increased, and vice versa, when the dust concentration is low, the water supply speed and the dust suction speed are reduced to adapt to the change of dust concentration.

[0039] The mine spray dust reduction system also includes a wind direction monitor 53. The support base 11 is provided with a turntable 12 that rotates around a vertical center axis. The support base 11 is provided with a motor 14 that drives the turntable 12 to rotate circumferentially around the vertical center axis. The support arm 13 is connected to the turntable 12. The central controller 51 is configured to control the motor 14 according to the received wind direction monitoring information to adjust the support arm 13 to a windward angle so that the sprayed water mist is directed in the direction of the dust, effectively humidifying the dust, and timely absorbing the dust floating in the wind direction with negative pressure, thereby improving the dust reduction effect.

[0040] In some embodiments, a first planar frame 21 and a second planar frame 22 are arranged opposite to each other on both sides of the support arm 13, the atomizing nozzles 31 are arranged in an array on the bottom surfaces of the first planar frame 21 and the second planar frame 22, and the dust suction nozzles 41 are arranged in an array on the top surfaces of the first planar frame 21 and the second planar frame 22.

[0041] Furthermore, the first planar frame 21 is connected to one side of the support arm 13 via a first hinge whose rotation axis is parallel to the length direction of the support arm 13, and the second planar frame 22 is connected to the other side of the support arm 13 via a second hinge whose rotation axis is parallel to the length direction of the support arm 13. Furthermore, the support arm 13 is provided with a first linear cylinder 23 for driving the first planar frame 21 to rotate around the first hinge, and a second linear cylinder 24 for driving the second planar frame 22 to rotate around the second hinge. The central controller 51 is respectively controlled and connected to the first linear cylinder 23 and the second linear cylinder 24, and is configured to independently adjust the angles of the first planar frame 21 and the second planar frame 22. This is to facilitate the adjustment of the angles of the first planar frame 21 and the second planar frame 22 respectively, to adjust the directions and angles of the two, and to adjust the spraying and dust collection angles and coverage range, so as to better perform dust reduction operations. For example, in Figure 1 On the basis of the plane frame being in a horizontal state, adjust to Figure 5The two plane frames shown are at an angle, which can concentrate the intensity of spray dust reduction and negative pressure dust suction in a small area and improve the dust reduction effect in a small area. Figure 6 When the two plane plate frames are tilted to one side, they can adapt to the effect of dust flying to one side affected by wind direction, so that the two plane plate frames face the direction of dust flying at the same time, thereby improving the dust reduction effect.

[0042] Furthermore, in some preferred embodiments, the mine spray dust reduction system also includes a wind direction monitor 53, which is signal-connected to the central controller 51 and is configured to control the first linear cylinder 23 and the second linear cylinder 24 according to the received wind direction monitoring information to adjust the unfolding angle of the planar frame so as to automatically adapt to the wind direction.
