[0002] In the operation links of mine exploitation, transportation, crushing, screening, etc., the generation of dust is inevitable. These dusts will not only reduce the visibility of the workplace, affect production efficiency, but also cause serious harm to the respiratory systems of workers. Long-term exposure may lead to occupational diseases such as pneumoconiosis. Therefore, under the increasingly strict environmental protection regulations and the pursuit of sustainable development goals by mining enterprises, people have developed fog boxes for suppressing dust diffusion. Through the water mist generated by the fog boxes, the diffusion of dust can be effectively suppressed and the dust concentration in the air can be reduced, providing a good working environment for workers. However, the traditional fog boxes are large in volume and heavy in weight, and cannot be applied to the narrow underground roadways, greatly reducing their usability and flexibility.

[0023] Please refer to Figures 1 to 6 A mine-used ultrasonic dry fog device as shown. The device body 1 includes a box body 11, an ultrasonic dry fog nozzle 12 connected to the box body 11, and a connection component 13 connecting two adjacent box bodies 11. The box body 11 is provided with a water supply channel 111 and a gas supply channel 112 along its length direction. Both the water supply channel 111 and the gas supply channel 112 are communicated with the ultrasonic dry fog nozzle 12. The connection component 13 is used to communicate the water supply channels 111 of two adjacent box bodies 11 and to communicate the gas supply channels 112 of two adjacent box bodies 11. The cross-section of the box body 11 is in a long strip shape. A plurality of box bodies 11 can be connected through the connection component 13 to form the device body 1. The gas supply channel 112 and the water supply channel 111 are arranged in parallel.

[0024] In the present invention, the box body 11 is the basic unit of the device. Its cross-sectional design in a long strip shape facilitates installation and layout in narrow roadways. Inside each box body 11, a water supply channel 111 and a gas supply channel 112 are provided to supply the necessary water and gas sources for the ultrasonic dry fog nozzle 12. The ultrasonic dry fog nozzle 12 is a component in the device that uses the ultrasonic principle to mix water droplets and air to form dry fog. The device body 1 is composed of a plurality of box bodies 11. These box bodies 11 are in a long strip shape and can be connected to each other through the connection component 13. Such a design enables the device body 1 to adjust the overall length of the device according to actual needs. Generally speaking, in the present invention, by setting the cross-section of the box body 11 to be in a long strip shape and providing a connection component 13 that can connect two adjacent box bodies 11, a plurality of box bodies 11 are connected in series through the connection component 13 to form a longer and more flexible device body 1. Users can adapt to different working length requirements by increasing or decreasing the number of box bodies 11 connected in series, enabling the device to be applicable to narrow underground roadways and other working environments with limited space, effectively improving the convenience and flexibility of the device. In addition, the gas supply channel 112 and the water supply channel 111 are arranged in parallel inside the box body 11. This design ensures that gas and water can be smoothly transported to the ultrasonic dry fog nozzle 12 through their respective channels without interfering with each other.

[0025] Further, the connection component 13 includes a connecting water pipe 131 connecting the water supply channels 111 of two adjacent boxes 11, and a connecting air pipe 132 connecting the air supply channels 112 of two adjacent boxes 11. The connecting water pipe 131 is threadedly connected to the water supply channel 111, and the connecting air pipe 132 is threadedly connected to the air supply channel 112.

[0026] In the present invention, the connecting water pipe 131 is used to connect the water supply channels 111 between two adjacent boxes 11 to ensure that water can flow smoothly from one box 11 to another box 11, providing a continuous and uniform water source for the entire device. Similarly, the connecting air pipe 132 is responsible for connecting the air supply channels 112 between two adjacent boxes 11 to ensure that gas can circulate throughout the device, providing the required air pressure conditions for the formation of dry mist at the ultrasonic dry mist nozzle 12. Further, the connecting water pipe 131 is threadedly connected to the water supply channel 111, and the connecting air pipe 132 is threadedly connected to the air supply channel 112. This connection method is not only convenient for installation and disassembly but also provides a good sealing effect, preventing water leakage and air leakage, ensuring the stable operation of the device, and making the mine-used ultrasonic dry mist device more flexible and convenient in assembly, maintenance, and adaptation to different working environments.

[0027] Further, the side of the box 11 is provided with a first connection hole 119 communicating with the air supply channel 112 and a second connection hole 1110 communicating with the water supply channel 111. The device body 1 includes an air supply elbow 113 with two ends respectively connected to an external air pipe and the first connection hole 119, and a water supply elbow 114 with two ends respectively connected to an external water pipe and the second connection hole 1110. The air supply elbow 113 and the water supply elbow 114 are respectively located on opposite sides of the box 11, and the opening directions of the air supply elbow 113 and the water supply elbow 114 are the same as the length direction of the box 11.

[0028] In the present invention, the first connection hole 119 is located on the side of the box body 11 and is used to connect the external air source and the air supply channel 112. It can introduce the air compressed by an external air pump from the external air pipe into the air supply channel 112 in the box body 11. The second connection hole 1110 is also located on the side of the box body 11 and is used to connect the external water source and the water supply channel 111 to ensure that water can smoothly flow into the water supply channel 111 in the box body 11. Further, one end of the air supply elbow 113 is connected to the external air pipe, and the other end is connected to the first connection hole 119, thereby introducing the external air source into the air supply channel 112. Similarly, one end of the water supply elbow 114 is connected to the external water pipe, and the other end is connected to the second connection hole 1110 to facilitate introducing water into the water supply channel 111. Further, the opening direction of the water supply elbow 114 and the opening direction of the air supply elbow 113 are the same as the length direction of the box body 11. Adopting such a design can optimize the direction and flow efficiency of the air flow and water flow, and at the same time enable the extension directions of the external water pipe and the external air pipe respectively connected to the water supply elbow 114 and the air supply elbow 113 to be the same as the length direction of the box body 11, thereby making the space occupied by the external water pipe and the external air pipe during the assembly with the device smaller, effectively improving the usability and integrity of the device. Preferably, threaded connections are adopted between the air supply elbow 113 and the first connection hole 119, and between the water supply elbow 114 and the second connection hole 1110. Such a design can effectively ensure the connection stability and sealing performance, preventing water leakage and air leakage.

[0029] Further, the ultrasonic dry fog nozzle 12 is provided with an exhaust pipe 121 that penetrates through the water supply channel 111 and is communicated with the air supply channel 112, a drain pipe 122 that is communicated with the water supply channel 111, and a gas-water collision part 123 for generating dry fog by mixing gas and water. The exhaust pipe 121 is provided with an exhaust channel 1211 that communicates the air supply channel 112 and the outside. The drain pipe 122 is provided with a drain channel 1221 that communicates the water supply channel 111 and the outside. The drain pipe 122 is located outside the exhaust pipe 121 and forms the drain channel 1221 with the exhaust pipe 121. The exhaust pipe 121 is provided with a plurality of negative pressure holes 1214 that communicate the drain channel 1221 and the exhaust channel 1211, and the negative pressure holes 1214 are located at the gas-water collision part 123.

[0030] In the present invention, the exhaust pipe 121 penetrates through the water supply channel 111 and communicates with the air supply channel 112. An exhaust channel 1211 is provided on the exhaust pipe 121 for guiding the compressed air in the air supply channel 112 to the air-water collision part 123. The drain pipe 122 communicates with the water supply channel 111 and is provided with a drain channel 1221. The drain pipe 122 is located outside the exhaust pipe 121, and the two together form the drain channel 1221, which means that water can be guided to the air-water collision part 123 through the drain pipe 122 to facilitate mixing with gas to generate dry fog. Specifically, a negative pressure hole 1214 communicating the drain channel 1221 and the exhaust channel 1211 is provided on the exhaust pipe 121. The position where the negative pressure hole 1214 is located is the position where air and water are mixed, that is, the air-water collision part 123. When the device works, air forms a high-speed air flow under the action of an external air pump, and the high-speed air flow sequentially flows through the air supply channel 112 and the exhaust channel 1211. Similarly, water forms a high-speed water flow under the action of an external water pump, and the high-speed water flow sequentially passes through the water supply channel 111 and the drain channel 1221. When the high-speed water flow and the high-speed air flow reach the negative pressure hole 1214, the negative pressure hole 1214 generates negative pressure under the action of the high-speed air flow, and the high-speed water flow enters the exhaust channel 1211 through the negative pressure hole 1214 under the action of this negative pressure and its own pressure, and collides with the high-speed air flow in the exhaust channel 1211, thereby forming tiny dry fog particles. In this way, a low-pressure environment conducive to air-water mixing can be created at the air-water collision part 123, making it easier for water to be broken into fine particles, forming a more uniform and finer dry fog. Such a design can further effectively control the dust in the mine environment. Further, a plurality of the ultrasonic dry fog nozzles 12 are uniformly distributed on one side of each of the boxes 11.

[0031] Further, the exhaust pipe 121 is provided with a first connection part 1212, the drain pipe 122 is provided with a second connection part 1222, the box 11 is provided with a first fitting hole 117 that is fitted and connected with the first connection part 1212, and a second fitting hole 118 that is fitted and connected with the second connection part 1222. The first fitting hole 117 communicates the air supply channel 112 and the water supply channel 111, and the second fitting hole 118 communicates the water supply channel 111 with the outside.

[0032] In the present invention, the first connecting portion 1212 is provided on the exhaust pipe 121 and is used for mating connection with the first mating hole 117 on the box body 11. This design ensures that the exhaust pipe 121 can be stably installed on the box body 11 and enables the exhaust pipe 121 to communicate with the air supply channel 112. Similarly, the second connecting portion 1222 is located on the drain pipe 122 and is used for mating connection with the second mating hole 118 on the box body 11 to ensure that the drain pipe 122 can be stably installed on the box body 11 and enables the drainage channel 1221 to communicate with the water supply channel 111. Specifically, the second connecting portion 1222 and the second mating hole 118 are in threaded mating connection. The threaded mating design can further ensure that the ultrasonic dry fog nozzle 12 is stably connected to the box body 11, improve the connection strength between the two, and prevent the water in the water supply channel 111 from leaking through the connection gap between the two. Further, a first limiting groove 12121 and a second limiting groove 12221 are respectively provided on the outer sides of the first connecting portion 1212 and the second mounting portion 1222. The ultrasonic dry fog nozzle 12 is provided with a first sealing ring 125 that is in mating connection with the first limiting groove 12121 and a second sealing ring 126 that is in mating connection with the second limiting groove 12221. And the diameter of the first sealing ring 125 is greater than the depth of the first limiting groove 12121, and the diameter of the second sealing ring 126 is greater than the depth of the second limiting groove 12221, so that the first sealing ring 125 and the second sealing ring 126 respectively protrude from the first limiting groove 12121 and the second limiting groove 12221. Adopting such a design can realize the positioning of the exhaust pipe 121 and the drain pipe 122 through the cooperation between the first sealing ring 125 and the first limiting groove 12121 and the cooperation between the second sealing ring 126 and the second limiting groove 12221. When the ultrasonic dry fog nozzle 12 is connected to the box body 11, the first sealing ring 125 abuts against the inner side wall of the water supply channel 111, and the second sealing ring 126 abuts against the outer side wall of the box body 11, effectively preventing the gas in the air supply channel 112 from leaking into the water supply channel 111 through the connection gap between the first connecting portion 1212 and the first mating hole 117, and at the same time preventing the water in the water supply channel 111 from leaking to the outside of the box body 11 through the connection gap between the second connecting portion 1222 and the second mating hole 118, further improving the connection stability and sealing performance between the ultrasonic dry fog nozzle 12 and the box body 11.

[0033] Further, a resonance portion 124 for atomizing water is provided on the side of the ultrasonic dry fog nozzle 12 away from the box body 11, and the axis of the resonance portion 124 coincides with the axis of the exhaust passage 1211.

[0034] In the present invention, the resonance part 124 is located on the side of the ultrasonic dry mist nozzle 12 away from the box body 11, that is, in the direction where the high-speed air flow discharges from the exhaust pipe 122. The resonance part 124 is used to further decompose water molecules into tiny droplets by using the principle of ultrasonic vibration, so as to form water mist. Specifically, the water entering the exhaust passage 1211 from the negative pressure hole 1214 follows the high-speed air flow in the exhaust passage 1211 and collides with the resonance part 124. Under the action of the high-speed air flow, the resonance part 124 will vibrate violently and then generate ultrasonic waves. The water discharged from the exhaust passage 1211 and the water discharged from the drainage passage 1222 are further atomized under the action of the ultrasonic waves, so as to improve the atomization effect of water. Further, the axis of the resonance part 124 coincides with the axis of the exhaust passage 1211. This design ensures that the gas flowing out of the exhaust passage 1211 can directly impact on the resonance part 124, thereby enhancing the water atomization effect. At the same time, the coincidence of the axes helps to maintain the uniformity and stability of the water mist.

[0035] Further, the length of the box body 11 is 1000 mm, the width is 42 mm, and the height is 63 mm.

[0036] In the present invention, the length of the box body 11 is 1000 mm. This length enables the box body 11 to maintain a certain degree of flexibility in design. It can be used alone or multiple box bodies 11 can be connected by connecting components 13 to form a larger system to adapt to working areas of different lengths. If the length of the box body 11 is too short, users will need to spend more time and labor to assemble it, which is not convenient for the use of the device. If the length of the box body 11 is too long, it cannot be applied to places with narrow spaces, reducing the flexibility of the device. Therefore, the box body 11 with this length is both convenient for users to use and can be applied to various mining environments. The width of the box body 11 is 42 mm and the height is 63 mm. Under this size, it can accommodate the required components and reduce the occupied space in the mining environment, further improving the overall efficiency of the device.

[0037] Further, the diameter of the air supply passage 112 is larger than the diameter of the water supply passage 111. The diameter of the air supply passage 112 is 20.5 mm, and the diameter of the water supply passage 111 is 10.5 mm.

[0038] In the present invention, the diameter of the air supply channel 112 is larger than that of the water supply channel 111. The diameter of the air supply channel 112 is 20.5 mm, and the diameter of the water supply channel 111 is 10.5 mm. Such a design can effectively control the balance between the flow rate and pressure of gas and water. The larger diameter of the air supply channel 112 helps to reduce the resistance during gas flow, while the smaller diameter of the water supply channel 111 helps to precisely control the water flow rate, ensuring that water enters the nozzle at an appropriate speed and pressure and mixes with the gas to generate dry fog. Therefore, through the parallel arrangement and reasonable design of the diameters of the air supply channel 112 and the water supply channel 111, the efficient transportation of gas and water is achieved, effectively ensuring the stability and efficiency of dry fog generation.

[0039] Furthermore, the device body 1 further includes a first plug 14 for blocking the water supply channel 111, a second plug 15 for blocking the air supply channel 112, and a third plug 16 and a fourth plug 17 respectively for blocking the first connection hole 119 and the second connection hole 1110.

[0040] In the present invention, the first plug 14 is used to block the water supply channel 111 to form a relatively sealed space in the water supply channel 111, ensuring that the pressure generated by the external water pump can be effectively transmitted to the ultrasonic dry fog nozzle 12. Similarly, the second plug 15 is used to block the air supply channel 112 to ensure that the air pressure generated by the external air pump can be effectively transmitted to the ultrasonic dry fog nozzle 12. The third plug 16 and the fourth plug 17 are respectively used to block the first connection hole 119 and the second connection hole 1110. When multiple such boxes 11 are connected in series using the connection component 13, one end of the air supply channel 112 not connected to the connection component 13 needs to be blocked by the second plug 15 to ensure that the pressure generated by the external air pump can be effectively transmitted to the ultrasonic dry fog nozzle 12. Similarly, one end of the water supply channel 111 not connected to the connection component 13 needs to be blocked by the first plug 14 to ensure that the air pressure generated by the external water pump can be effectively transmitted to the ultrasonic dry fog nozzle 12. Similarly, when multiple boxes 11 are connected in series using the connection component 13, the device will have multiple first connection holes 119 and second connection holes 1110. At this time, the user can choose to connect one water supply elbow 114 and one air supply elbow 113, or can choose to connect multiple water supply elbows 114 and air supply elbows 113. The second connection holes 1110 and the first connection holes 119 not connected to the water supply elbow 114 and the air supply elbow 113 need to be blocked by the fourth plug 17 and the third plug 16 respectively to ensure that the water pressure and air pressure in the water supply channel 111 and the air supply channel 112 can be effectively transmitted to the ultrasonic dry fog nozzle 12. Such a design enables the device to ensure functionality while improving the flexibility of device use.

[0041] Further, on opposite sides of the box body 11, there are respectively a first groove 115 for embedding an external water pipe and a second groove 116 for embedding an external air pipe. The first groove 115 and the water supply elbow 114 are on the same side of the box body 11, and the second groove 116 and the air supply elbow 113 are on the same side of the box body 11. Both the water supply elbow 114 and the air supply elbow 113 are located at the middle position of the box body 11 along the length direction.

[0042] In the present invention, the first groove 115 is located on one side of the box body 11 for embedding an external water pipe, effectively preventing the connection between the water pipe and the water supply elbow 114 from loosening, and at the same time avoiding the chaos of the water pipe outside the box body 11. Similarly, the second groove 116 is located on the other side of the box body 11, opposite to the first groove 115, for embedding an external air pipe, effectively preventing the connection between the air pipe and the air supply elbow 113 from loosening, and at the same time avoiding the chaos of the air pipe outside the box body 11, effectively improving the neatness and safety of the external connection pipelines of the device, and further improving the integrity of the device.

[0043] Embodiment 1 A mine-used ultrasonic dry fog device, the device body 1 includes a box body 11, an ultrasonic dry fog nozzle 12 connected to the box body 11, and a connection component 13 connecting two adjacent box bodies 11. The box body 11 is provided with a water supply channel 111 and an air supply channel 112 along its length direction. Both the water supply channel 111 and the air supply channel 112 are communicated with the ultrasonic dry fog nozzle 12. The connection component 13 is used to communicate the water supply channels 111 of two adjacent box bodies 11 and to communicate the air supply channels 112 of two adjacent box bodies 11. The cross-section of the box body 11 is in a long strip shape, and multiple box bodies 11 can be connected through the connection component 13 to form the device body 1. The air supply channel 112 and the water supply channel 111 are arranged in parallel.

[0044] Embodiment 2 On the basis of Embodiment 1, Embodiment 2 also has the following implementation manners: The connection component 13 includes a connection water pipe 131 connecting the water supply channels 111 of two adjacent box bodies 11 and a connection air pipe 132 connecting the air supply channels 112 of two adjacent box bodies 11. The connection water pipe 131 is threadedly connected to the water supply channel 111, and the connection air pipe 132 is threadedly connected to the air supply channel 112.

[0045] Embodiment 3 On the basis of Embodiment 1, Embodiment 3 also has the following implementation manners: On the side of the box body 11, there are a first connection hole 119 communicating with the air supply channel 112 and a second connection hole 1110 communicating with the water supply channel 111.
