Description

Technical Field

[0001] This utility model is an open-pit mine blasting isolation and noise reduction device, belonging to the field of mining technology. Background Technology

[0002] Open-pit mining involves stripping away the topsoil and surrounding rock of the ore body, transporting the waste rock to a spoil heap, and directly extracting ore from the exposed ore body. When the ore body is shallowly buried or has an outcrop, open-pit mining is superior to underground mining. Open-pit mining consists of three stages: stripping, mining, and trenching. Its main production processes include: drilling, blasting, loading of ore (rock), transportation of ore and rock, and unloading of rock.

[0003] Chinese Patent Publication No. CN221886939U discloses a blasting device for open-pit mining. By setting up a human infrared sensor, the protective cover can be automatically closed when the worker leaves, preventing the situation where the protective cover is forgotten to be closed, thus effectively avoiding accidents caused by the detonator being accidentally touched. However, the blasting process will raise a large amount of dust and rocks, and generate a lot of noise, resulting in a chaotic blasting site. There is an urgent need for an open-pit mining blasting isolation and noise reduction device to solve the above-mentioned problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an open-pit mine blasting isolation and noise reduction device, comprising noise-reducing honeycomb baffles, a dust-spraying mechanism, a buffer bag, an explosion-proof steel wire mesh, a PLC controller, a wind direction sensor, and a traction buckle.

[0006] Furthermore, the fixing clip at the left end of each noise-reducing honeycomb baffle is located above the fixing clip at the right end. The two corresponding fixing clips are connected to the two noise-reducing honeycomb baffles by fixing them to the connecting rod.

[0010] The beneficial effects of this utility model are as follows: This utility model provides an open-pit mine blasting isolation and noise reduction device. Because it incorporates a noise-reducing honeycomb baffle, a dust-reducing spraying mechanism, a PLC controller, and a wind direction sensor, it controls the water pump to open during blasting, causing the spraying casing to spray water mist onto the blasting site. The water mist can carry away the raised dust, accelerating its fall to the ground. The wind sensor detects the wind direction and force and transmits these signals to the PLC controller. The PLC controller then increases the power of the water pump on the side with the stronger wind and the direction of the wind, thereby spraying more water mist and improving the dust reduction effect. The noise-reducing honeycomb baffle allows air to rub and adhere to the pore walls within the micropores, consuming the air's kinetic energy and reducing sound propagation. Furthermore, before blasting, the buffer zone is filled with a non-Newtonian fluid, which buffers the impact of the blast, further enhancing the dust reduction effect. Attached Figure Description

Detailed Implementation

[0020] Please see Figures 1-6 This utility model provides a technical solution: an open-pit mine blasting isolation and noise reduction device, including a noise-reducing honeycomb baffle 1, a dust spraying mechanism 2, a buffer bag 3, an explosion-proof steel wire mesh 4, a PLC controller 5, a wind direction sensor 6, and a traction buckle 7. Each dust spraying mechanism 2 has a noise-reducing honeycomb baffle 1 installed on both sides. Several noise-reducing honeycomb baffles 1 and several dust spraying mechanisms 2 are provided. Explosion-proof steel wire mesh 4 is installed on the inner side of each noise-reducing honeycomb baffle 1. A buffer bag 3 is installed on the upper surface of the explosion-proof steel wire mesh 4. The explosion-proof steel wire mesh 4 is connected to the corresponding dust spraying mechanism 2 via the traction buckle 7. The PLC controller 5 is equipped with... Placed on the outside of the noise reduction honeycomb baffle 1, each dust spraying mechanism 2 has a wind direction sensor 6 installed on its upper surface. The dust spraying mechanism 2 includes a spraying shell 21, a water pump 22, a water supply pipe 23, a water spraying shell 24, and a water spray head 25. The water pump 22 is installed inside the spraying shell 21, the water spraying shell 24 is installed on the upper surface of the spraying shell 21, and several water spray heads 25 are installed on the upper surface of the water spraying shell 24. The water supply pipe 23 is installed inside the spraying shell 21. This design solves the problem that the original device would raise a large amount of dust and rocks during blasting, and at the same time generate huge noise, resulting in a relatively chaotic blasting site.

[0021] As the first embodiment of this utility model: the fixing clip 11 at the left end of each noise-reducing honeycomb baffle 1 is located above the fixing clip 11 at the right end. The two corresponding fixing clips 11 are connected to the two noise-reducing honeycomb baffles 1 by fixing them to the connecting rod 12. The corresponding fixing clips 11 are connected to the noise-reducing honeycomb baffle 1 and the spray housing 21 by fixing them to the circumferential surface of the spray housing 21. The fixing clips 11 are locked by fixing bolts. The noise-reducing honeycomb baffle 1 is made of a micro-perforated plate. The upper surface of the buffer bag 3 is provided with a filling port. The inside of the buffer bag 3 is filled with a non-Newtonian liquid. The hexagonal positions of the explosion-proof wire mesh 4 are all provided with traction buckles. 7. Each explosion-proof wire mesh 4 is connected to the adjacent explosion-proof wire mesh 4 and the spray shell 21 through a traction buckle 7. By adding non-Newtonian liquid, the non-Newtonian fluid can exhibit a harder stiffness during blasting, thereby cooperating with the explosion-proof wire mesh 4 to buffer the impact force generated during blasting. The water pump 22 is connected to the spray shell 21 through a water supply pipe 23. The water pump 22 is connected to the external water tank through a water supply pipe 23. The water nozzle 25 is interconnected with the corresponding water spray shell 24. The output end of the wind direction sensor 6 is electrically connected to the input end of the PLC controller 5. The output end of the PLC controller 5 is electrically connected to the input end of the water pump 22.

[0022] As a second embodiment of this utility model: When setting up a blasting site, according to the area of ​​the blasting site, a corresponding number of noise-reducing honeycomb baffles 1, dust-reducing spraying mechanisms 2, explosion-proof wire mesh 4, wind direction sensors 6, and buffer belts are set up. Adjacent noise-reducing honeycomb baffles 1 are connected to each other by fixing clips 11 and connecting rods 12. Then, the noise-reducing honeycomb baffles 1 next to the spraying shell 21 are fixed to the surface of the spraying shell 21 by fixing clips 11. During blasting, the water pump 22 is turned on, so that the spraying shell 21 sprays water mist into the blasting site. The water mist can carry away the raised dust and accelerate its fall to the ground. Furthermore, the wind sensor can detect wind direction and force, and transmit the wind direction and force signals to the PLC controller 5. The PLC controller 5 will then control the side with stronger wind and the end of the direction to increase the power of the water pump 22, thereby spraying more water mist and improving the dust reduction effect. The noise reduction honeycomb baffle 1 can reduce the propagation of sound by allowing air to rub and adhere to the pore walls in the micropores, thereby reducing the kinetic energy of the air. At the same time, before the explosion, the buffer zone is filled with non-Newtonian fluid. During the explosion, the non-Newtonian fluid can buffer the impact force of the explosion, thereby further improving the dust reduction effect.
