[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Refer to Figures 1-4 , the present invention discloses an automatic high-pressure atomization dust suppression system for head breaking and unloading. This automatic high-pressure atomization dust suppression system for head breaking and unloading can automatically identify and determine whether a transport truck 600 enters the unloading area, and automatically control the start of dust suppression operations to reduce the generation and diffusion of dust and meet the requirements of environmental protection at the production site.

[0022] Specifically, as Figure 1 shown, this automatic high-pressure atomization dust suppression system for head breaking and unloading includes a rectangular unloading port 700 for unloading the transport truck 600, including: a spray device 100, which includes a horizontally arranged installation water pipe 101. A number of spray nozzles 102 are arranged along the length direction of the installation water pipe 101. The spray nozzles 102 are arranged in a line on one side of the installation water pipe 101. The number of spray devices 100 is set to three. The three spray devices 100 are respectively arranged on the side above the unloading port 700 and enclose a U shape. The water outlet direction of the spray nozzles 102 faces the opening direction of the unloading port 700. On this basis, as Figure 2 shown, each spray device 100 is provided with two installation water pipes 101 distributed vertically and horizontally to increase the water mist content for dust suppression; a water supply station 200, which is connected to the installation water pipe 101 through a pipeline to supply high-pressure water for the spray nozzles 102; a control unit 300, which is used to detect whether the transport truck 600 is approaching the unloading port 700, is arranged on the side of the unloading port 700 where the spray device 100 is not provided. A limit pier 500 for limiting the traveling position of the tires of the transport truck 600 is also arranged on this side. The control unit 300 is connected to the water supply station 200 to control the start and stop of water supply; a circulation fan 400, which is arranged on the lower side of the unloading port 700, and a circulation fan 400 is arranged below each spray device 100.

[0023] When working, as Figure 4 shown, the control unit 300 detects and judges whether a transport truck 600 preparing to unload raw materials enters the unloading area. After determining that a truck enters the unloading area, the control unit 300 feeds the judgment signal back to the water supply station 200, and the water supply station 200 (high-pressure water pump) starts to work to provide high-pressure water source to the installation water pipe 101, so that the spray nozzles 102 around the unloading port 700 form a dense high-pressure spray, and the dust is condensed by the water mist and the dust falls downward.

[0024] Meanwhile, the circulating fan 400 is in a long-term working state. The circulating fan 400 in long-term operation is used to form an air flow that converges from the four directions around the discharge opening 700 towards the discharge opening 700 and moves downward around the discharge opening 700. This air flow is used to promote the condensation and sinking of the dust during the water mist dust suppression process and prevent the dust from escaping during the non-water mist dust suppression process.

[0025] Among them, as Figure 1 and Figure 4 shown, in order to prevent the circulating fan 400 from being impacted by the falling stones during the discharging process beyond the inner edge range of the discharge opening 700, the circulating fan 400 is arranged on the side of the discharge opening 700 away from the opening direction. To form sufficient wind power and ensure the dust suppression effect, multiple circulating fans 400 are arranged below each spraying device 100, and the circulating fans 400 are arranged in a row along the length direction of the spraying device 100.

[0026] Among them, the control unit 300 is as Figure 3 shown. The control unit 300 includes a PLC controller 301 and two groups of photoelectric switches 302. The PLC controller 301 is simultaneously connected to the photoelectric switches 302 and the water supply station 200 in terms of signals. As Figure 1 and Figure 4 shown, the two groups of photoelectric switches 302 are arranged on the upper side of the discharge opening 700, on the side of the discharge opening 700 where the spraying device 100 is not arranged and away from the opening direction of the discharge opening 700, and the two groups of photoelectric switches 302 are arranged in a row along the direction away from the discharge opening 700. Further, the control unit 300 further includes a three-color lamp 303, and the three-color lamp 303 is connected to the PLC controller 301.

[0027] During the discharging process, the rear of the transport truck 600 slowly approaches the discharge opening 700 from the direction away from the discharge opening 700. The photoelectric switch 302 arranged farthest from the discharge opening 700 first identifies the obstacle (transport truck 600). At this time, the yellow light of the three-color lamp 303 can be used to prompt that the spraying function of the automatic high-pressure atomization dust suppression system for the head break discharging is about to start operating, and at the same time prompt the driver of the transport truck 600 that it is about to approach the discharge opening 700 and needs to pay attention to observation. When the other group of photoelectric switches 302 identifies the obstacle (the transport truck 600 affects both groups of photoelectric switches 302 at the same time), the high-pressure spraying operation is started. At this time, the red light prompts and warns the driver that it is about to approach the edge of the discharge opening 700 and special attention needs to be paid to observation to ensure correct parking operation.

[0028] After the transport truck 600 finishes discharging, the transport truck 600 moves forward to leave the recognition range of the control unit 300. After a period of time when both groups of photoelectric switches 302 are not affected at the same time, such as 30 seconds or 1 minute later, the spraying stops operating. However, the operation of the circulating fan 400 always continues.

[0029] Further, in order to ensure accurate judgment by the photoelectric switch 302, the photoelectric switch 302 is a transmissive photoelectric sensor, such as Figure 1 The two paired photoelectric sensors shown are respectively arranged on both sides in the direction away from the opening of the discharge port 700.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
