A dust suppression device for mine roadways

Abstract

This utility model discloses a dust suppression device for mine roadways, belonging to the technical field of dust suppression equipment. It includes a water tank, a housing, and an atomizing nozzle. A bearing is fixedly connected to the surface of the atomizing nozzle, and fan blades arranged in a circular array are fixedly connected to the outer ring of the bearing. A first pulley is fixedly connected to the back of the outer ring of the bearing. A drive motor is fixedly connected to the inner wall of the housing, and a second pulley is fixedly connected to the output end of the drive motor. The surface of the first pulley is connected to the second pulley via a belt. In this utility model, the output end of the drive motor drives the second pulley to rotate, which in turn drives the first pulley to rotate via the belt, thereby rotating the outer ring of the bearing. This causes the fan blades to move, thus creating airflow. This mixes the water mist sprayed from the atomizing nozzle with the air, increasing the mixing speed of the water mist with dust in the air and improving the dust suppression effect. The housing can be lifted upwards using a handle.

However, atomizing nozzles generally cannot be detached from the equipment, which is not conducive to directly spraying the dust-generating location. The mixing efficiency of water mist and air is low, resulting in insufficient dust suppression effect. Utility Model Content

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-6 As shown, the dust suppression device for mine roadways provided in this embodiment includes a water tank 1, a housing 2, and an atomizing nozzle 3. A bearing 4 is fixedly connected to the surface of the atomizing nozzle 3, and fan blades 5 arranged in a circular array are fixedly connected to the outer ring of the bearing 4. A first pulley 6 is fixedly connected to the back of the outer ring of the bearing 4. A drive motor 7 is fixedly connected to the inner wall of the housing 2. A second pulley 8 is fixedly connected to the output end of the drive motor 7. The surface of the first pulley 6 is connected to the second pulley 8 via a belt. When the atomizing nozzle 3 sprays water, the output end of the drive motor 7 drives the second pulley 8 to rotate. The second pulley 8 drives the first pulley 6 to rotate via a belt, thereby driving the outer ring of the bearing 4 to rotate, causing the fan blades 5 to drive airflow, mixing the water mist sprayed by the atomizing nozzle 3 with the air, increasing the mixing speed of the water mist with the dust in the air, and improving the dust suppression effect.

[0026] In this embodiment, as Figures 1-6As shown, a protective frame 9 is fixedly connected to the inner wall of the outer casing 2. During use, the protective frame 9 makes it difficult for the user to touch the fan blades 5, improving the safety of the device. A handle 11 is fixedly connected to the upper surface of the outer casing 2, and a filter screen 10 is fixedly connected to the inner wall of the outer casing 2. When the fan blades 5 rotate, air enters the interior of the outer casing 2 through the filter screen 10. The air is filtered by the outer casing 2, and when the fan blades 5 rotate, it is difficult for debris to enter the outer casing 2. The surface of the filter screen 10 is fixedly connected to the atomizing nozzle 3, and a handle 20 is fixedly connected to the lower surface of the outer casing 2. The lower surface of the handle 20... An insertion hole 21 is provided, and an elastic block 22 is provided on the inner wall of the insertion hole 21. An installation plate 17 is fixedly connected to the upper surface of the water tank 1, and an insertion rod 18 is fixedly connected to the upper surface of the installation plate 17. A mating groove 19 is provided on the surface of the insertion rod 18. By lifting the outer shell 2 upward by the handle 11, the elastic block 22 is forced to undergo elastic deformation, thereby causing the elastic block 22 to disengage from the mating groove 19, causing the insertion hole 21 to slide with the insertion rod 18, further disengaging the handle 20 from the insertion rod 18, lifting the outer shell 2, and then manually controlling the spray direction of the atomizing nozzle 3.

[0027] In this embodiment, as Figures 1-6 As shown, a mounting box 12 is installed inside the water tank 1. A high-pressure water pump 13 is fixedly connected to the inner wall of the mounting box 12. A water pumping pipe 14 is fixedly connected to the input end of the high-pressure water pump 13, and a connecting pipe 15 is fixedly connected to the output end of the high-pressure water pump 13. A diversion pipe 16 is fixedly connected to one end of the connecting pipe 15. The surface of the diversion pipe 16 is connected to the atomizing nozzle 3 through a flexible hose. The high-pressure water pump 13 draws water from inside the water tank 1 through the water pumping pipe 14, and the high-pressure water pump 13 inputs water into the diversion pipe 16 through the connecting pipe 15. Water is fed into the atomizing nozzle 3 through the hose on the diverter pipe 16, causing the atomizing nozzle 3 to spray. A water inlet 23 is fixedly connected to the front of the water tank 1, and a connecting rope 24 is fixedly connected to the surface of the water inlet 23. A cover 25 is fixedly connected to one end of the connecting rope 24. Water is added into the water tank 1 through the water inlet 23. After the water is added, the cover 25 is inserted into the water inlet 23 to block the water inlet 23, making it difficult for debris to enter the water tank 1. The connecting rope 24 is connected to the cover 25, making it difficult for the cover 25 to be lost.

[0028] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the dust suppression device for mine roadways provided in this embodiment is as follows:

[0029] Step 1: Move the device to the work site;

[0030] Step 2: Add water into the water tank 1 through the water inlet 23. After adding water, insert the cap 25 into the water inlet 23.

[0031] Step 3: The high-pressure water pump 13 draws water from the water tank 1 through the water pipe 14. The high-pressure water pump 13 is then fed into the diversion pipe 16 through the connecting pipe 15. The water is fed into the atomizing nozzle 3 through the hose on the diversion pipe 16, causing the atomizing nozzle 3 to spray. At the same time, the output end of the drive motor 7 drives the second pulley 8 to rotate. The second pulley 8 drives the first pulley 6 to rotate through the belt, thereby driving the outer ring of the bearing 4 to rotate, causing the fan blade 5 to drive the airflow. This mixes the water mist sprayed from the atomizing nozzle 3 with the air, increasing the mixing speed of the water mist with the dust in the air and improving the dust suppression effect.

[0032] Step four: Lift the outer casing 2 upwards using handle 11, thereby manually controlling the spray direction of the atomizing nozzle 3.

[0033] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
