Technical Field

[0001] The invention relates to the technical field of blasting dust suppression, in particular to an environmentally friendly blasting dust prevention and suppression device. Background Art

[0002] During the mining construction process, blasting operations are common, but blasting will cause a lot of smoke and dust, seriously affecting the surrounding environment. To effectively solve this problem, water spraying dust reduction measures are usually implemented with the help of dust reduction devices. Water acts as a separator here, which can separate the particles in the smoke and dust, thereby achieving the purpose of reducing smoke concentration, purifying the air, and reducing pollution to the surrounding environment.

[0003] In the existing dust suppression water spray device technology, most of them rely on motors to drive the nozzle to rotate, so that the water flow can cover a large area of the blasting area and achieve the purpose of dust suppression. However, the frequent forward and reverse operations of the motor can easily cause the motor to overheat, which will significantly shorten the service life of the motor. During the dust suppression operation, if the motor is damaged due to overheating or other reasons, the nozzle will not be able to flexibly adjust the spray angle, which will greatly reduce the dust suppression quality of the dust suppression device and the dust suppression efficiency will be significantly reduced, making it difficult to effectively suppress the pollution of the environment by the smoke generated by blasting.

[0023] See also Figures 1 to 5 , the present invention provides the following technical solutions:

[0025] When in use, the base 1 can be fixed to the water truck by bolts 9, the support rod 3 can provide stable support for the water collecting tank 4, and the delivery hose 6 is connected to the pump on the water truck. The water truck pump can transport the water inside the water truck to the water collecting tank 4 through the delivery hose 6, and then spray it out through the nozzle 5 on the water collecting tank 4. The sprayed water can separate the smoke particles in the air and reduce the pollution of blasting smoke to the environment.

[0026] Embodiment 2: This embodiment differs from the embodiment 1 in that the technical solution includes: a limiting mechanism 8 is provided on the base 1, the limiting mechanism 8 includes a support seat 81, a round rod 82 is rotatably connected to the support seat 81, a limiting seat 83 is fixedly connected to the round rod 82, a symmetrically arranged rubber layer 84 is fixedly connected to the limiting seat 83, the support seat 81 is fixedly connected to the top of the base 1, and the specific shape of the limiting seat 83 is a C-shaped arrangement;

[0027] The base 1 is provided with an adjustment mechanism 7 for adjusting the injection angle of the nozzle 5. The adjustment mechanism 7 includes a sliding groove 71, a driven plate 72, a vertical rod 73 and a vertical rod 74. The sliding groove 71 is fixedly connected to a symmetrically arranged spring 75. The bottom end of the driven plate 72 is fixedly connected to a connecting rod 76. The bottom end of the connecting rod 76 is fixedly connected to an extrusion block 77. The bottom end of the driven plate 72 is fixedly connected to an extrusion plate 78. An isolation plate 79 is slidably connected to the vertical rod 73. A strong magnet 701 is fixedly connected to the top of the vertical rod 74. The sliding groove 71 is opened on the base 1. The driven plate 72 is fixedly connected to the support rod 3. The vertical rod 73 has a total of Two, the vertical rods 73 are fixedly connected to the top of the base 1, and there are two vertical rods 74. The vertical rods 74 are fixedly connected to the top of the base 1 and the adjacent position of the vertical rod 73. The middle position of the bottom end of the driven plate 72 is slidably connected to the limit seat 83. The rubber layer 84 abuts the outer wall of the driven plate 72. The specific shape of the extrusion block 77 is a circular setting. The extrusion block 77 is slidably connected to the inside of the sliding groove 71. The specific shape of the sliding groove 71 is annular. The magnetic attraction force of the strong magnet 701 is greater than the elastic performance of the spring 75. One end of the extrusion plate 78 is inclined. The raw material of the isolation plate 79 is Permalloy;

[0028] When in use, before the nozzle 5 sprays water, the staff can directly rotate the limit seat 83. The rotation of the limit seat 83 will drive the round rod 82 to rotate. During the rotation of the limit seat 83, the rubber layer 84 will rub against the outer wall of the driven plate 72. When the limit seat 83 rotates and separates from the driven plate 72, the blasting smoke source can be sprayed through the external water pump, the delivery hose 6 and the nozzle 5. At this time, the limit of the driven plate 72 is released, and the strong magnet 701 will generate a great magnetic attraction to the driven plate 72. At this time, the driven plate 72 will rotate in the direction of the strong magnet 701. The rotation of the driven plate 72 will drive the support rod 3 to rotate, and the support rod 3 will drive the water collecting tank 4 and the nozzle 5 to rotate. At this time, the spraying angle of the nozzle 5 will be adjusted. The rotation of the driven plate 72 will also drive the connecting rod 76 and the extrusion block 77 to rotate. The extrusion block 77 that follows the rotation will slide in the sliding groove 71. The extrusion block 77 will squeeze and contract the corresponding spring 75 during the process of rotating in the direction of the strong magnet 701. At the same time, the rotation of the driven plate 72 will also drive the extrusion plate 78 to rotate in the direction of the strong magnet 701. The extrusion plate 78 will squeeze the bottom end of the isolation plate 79 during the rotation process. At this time, the isolation plate 79 will be pressed and move upward during the rotation of the driven plate 72. The movement of the isolation plate 79 is guided by the vertical rod 73. When the driven plate 72 rotates to a position close to the strong magnet 701, the isolation plate 79 has also risen to a position corresponding to the strong magnet 701. Figure 4At this time, the isolation plate 79 made of Permalloy will greatly weaken the magnetic attraction of the strong magnet 701 on the driven plate 72. Then, the squeezed spring 75 will drive the squeezing block 77 to return to its original position. At this time, the squeezing block 77 will drive the driven plate 72 to return to its original position through the connecting rod 76. The driven plate 72 will drive the support rod 3, the water collecting tank 4 and the nozzle 5 to return and rotate. The spray angle of the nozzle 5 is adjusted again during the reset process. At this time, the squeezing plate 78 will no longer squeeze the isolation plate 79. At this time, the isolation plate 79 will return downward to its original position. When the squeezing block 77 is driven to return to its original position by one of the springs 75, its impact force will squeeze the other spring 75, and the other The spring 75 will shrink and absorb the impact force from the extrusion block 77, and then suddenly drive the extrusion block 77 to return to the middle position inside the sliding groove 71. At this time, the strong magnet 701 will magnetize the driven plate 72 again, and the process of rotating the nozzle 5 to adjust the spray angle will be repeated again. This repetition can make the sprayed water separate the smoke and dust particles in the air. The adjustment mechanism 7 will not be easily damaged during work like a motor, ensuring that the nozzle 5 can continuously and stably adjust the spray angle during the dust reduction process, allowing the sprayed water flow to continuously cover the blasting smoke and dust area, improving the efficiency of the dust reduction device in using water to separate smoke and dust in the air, avoiding the problem of reduced dust reduction quality and efficiency of the dust reduction device due to damage to key components, and ensuring that the dust reduction work is stable and reliable.
