Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0020] The object of the present invention is to provide a multi-functional dust suppression device for the open-pit coal mining and loading link to solve the problems existing in the above-mentioned prior art, which can effectively control the dust generated in the open-pit coal mining and loading operation, lock the dust generation points, adjust the spraying equipment, enhance the dust-catching performance of spraying, automatically turn on or off the dust suppression equipment, significantly improve the dust suppression efficiency of the open-pit coal mine, greatly reduce the dust suppression cost, and at the same time enhance the production safety.
[0021] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] As Figure 1 - Figure 2 shown, the present invention provides a multi-functional dust suppression device for the open-pit coal mining and loading link, including a frame 1, a water storage tank 2, a generator set 3, a fog cannon 4, a high-pressure water cannon 5, a telescopic frame 6, a water supply pipe 7, an infusion pipe 8, a high-pressure fog pile 9, a fog pile main unit 10, a dust suppressant adding device 11, a camera 12, an environment monitoring device 13, an algorithm box 14, a bag filter 15, a self-cleaning filter 16, a high-pressure water pump 17, and a total control electric box 18.
[0023] In one embodiment, the water storage tank 2 supplies water to the spraying device through the water supply pipe 7, and the water supply pipe 7 successively penetrates through the high-pressure water pump 17, the self-cleaning filtration device 16, and the bag filter 15; a high-pressure fog pile 9 is installed on each side of the high-pressure water pump 17; high-pressure water cannons 5, a dust suppressant adding device 11, a fog pile main unit 10, and a main control electric box 18 are installed on both sides of the water supply pipe 7. The high-pressure water cannon 5 is installed on the telescopic frame 6, and an algorithm box 14 is installed below the telescopic frame 6; a fog cannon 4 is installed at the very tail of the vehicle frame 1; the infusion pipe 8 is communicated with the water supply pipe 7; the algorithm box is respectively connected to the control cabinet of the fog cannon 4, the high-pressure water cannon 5, the fog pile main unit 10, the camera 12, and the environmental monitoring device 13 through data transmission lines. The fog pile main unit 10 is connected to the high-pressure fog pile 9 through data transmission lines and water delivery pipes respectively; the generator set 3 is connected to the main control electric box 18 through power transmission lines, and the main control electric box 18 is respectively connected to the control cabinet of the fog cannon 4, the high-pressure water cannon 5, the fog pile main unit 10, the camera 12, the environmental monitoring device 13, the dust suppressant adding device 11, the algorithm box 14, the high-pressure water pump 17, the self-cleaning filter 16, and the bag filter 15 through power transmission lines.
[0024] The camera 12 collects the action pictures of the bucket of the loading and unloading electric shovel and transmits data to the algorithm box 14 through the data transmission line; the environmental monitoring device 13 collects data such as wind direction, wind speed, temperature, and humidity at the loading and unloading operation site and transmits data to the algorithm box 14 through the data transmission line; the algorithm box 14 collects the data and converts it into a control signal through a special algorithm. When the wind speed is low, it controls the fog cannon 4 to start and rotates it to aim at the dust generation point for dust reduction. When the wind speed is high, it controls the telescopic frame 6 to rise and turns on the high-pressure water cannon 5 to aim at the dust generation point for dust reduction; when there is dust diffusion close to the equipment, the algorithm box 14 issues a control signal to control the high-pressure fog pile 9 to swing and capture the dust. The algorithm box 14 can adopt a commercially available PLC integrated circuit board or a control center that can meet the above control requirements.
[0025] A stirrer, a heater, and a remaining amount display device are installed inside the dust suppressant adding device 11. The stirrer can complete the mixing of the dust suppressant in water by using a conventional spiral stirring. The heater heats the dust suppressant and the water flow to increase the fusion. The remaining amount display device is used to display the remaining amount of the dust suppressant. The stirrer, the heater, and the remaining amount display device can all adopt commercially available conventional parts. Add the dust suppressant raw material into the dust suppressant adding device 11. After the dust suppressant is dissolved, the dust suppressant solution is transported into the water supply pipe 7 through the infusion pipe 8. When the fog cannon 4, the high-pressure water cannon 5, and the high-pressure fog pile 9 are turned on, the water mixed with the dust suppressant solution is sprayed towards the dust generation point, enhancing the dust capture performance of the spray and improving the dust reduction efficiency.
[0026] The high-pressure water pump 17 transports the water in the water storage tank to the self-cleaning filter 16 and the bag filter 15 to prevent the spray equipment from being blocked. Moreover, the fog cannon 4, the high-pressure water cannon 5, and the high-pressure fog piles 9 are equipped with heating and anti-freezing devices, and common commercially available devices can be used for the heating and anti-freezing devices. The above designs improve the reliability and stability of the equipment.
[0027] An anti-collision warning system is installed inside the cab of the vehicle frame 1, which improves the safety during the use of the equipment; noise reduction devices are installed inside the fog cannon 4 and the generator set 3, reducing the occupational hazards suffered by the operating workers.
[0028] The multi-functional dust suppression equipment for the open-pit coal mining and loading link of the present invention has the following characteristics:
[0029] First, the algorithm box 14 collects the data of the camera 12 and the environmental monitoring device 13, and through special algorithm analysis, first selects which dust suppression mechanism to use according to the analysis results. The fog cannon 4 is used at low wind speeds, and the high-pressure water cannon 5 is used at high wind speeds, ensuring that the dust suppression device is used under working conditions suitable for its characteristics, observing the mixing situation of the spray and the dust generation point, achieving precise dust suppression, and not being overly deflected by the wind flow.
[0030] Second, the dust suppressant adding device 11 can quickly dissolve the dust suppressant raw materials through the internal stirring device and heating device, and can always display the remaining amount of the internal liquid medicine and transmit information to the display screen, ensuring that the fog droplets sprayed by the dust suppression device have good dust-catching performance;
[0031] Third, for the high-pressure fog piles 9, by installing the high-pressure fog piles 9 on the left and right sides of the tail of the vehicle frame 1 respectively, the dust that has not been captured by the fog cannon 4 or the high-pressure water cannon 5 can be further captured, further reducing the dust emission, and at the same time protecting the lenses of the camera 12 from being covered by dust.
[0032] It should be noted that for those skilled in the art, obviously the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
