[0001] This utility model relates to the field of dust treatment technology, and more specifically, to a water mist dust suppression device for a feeding corridor. Background Technology

[0002] Belt conveyors are commonly used in mining, metallurgy, and chemical industries to transport solid materials. The conveying process, especially at loading, unloading, and belt junctions, generates significant amounts of dust, causing serious environmental pollution. Traditional dust suppression measures include high-pressure spray nozzles to spray water mist and air extraction within the conveyor corridor. High-pressure sprays produce large water droplets and a large volume of water, quickly forming large amounts of water on the ground near the spray nozzles. Furthermore, the inherent limitations of airtight corridors make air extraction systems complex, energy-intensive, and ineffective. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0020] Example This utility model provides a water mist dust suppression device for a feeding corridor, such as Figure 1 , Figure 2 As shown, the system includes an mounting frame 2 installed within a feeding corridor. The mounting frame 2 has an H-shaped frame structure. Two sets of conveying pipes 4 are installed on the side walls of the mounting frame 2, extending along the feeding corridor. Multiple sets of conveying pipes 4 can be sequentially installed within the feeding corridor to shorten the movement path of the water mist. Several nozzles 8 are equidistantly arranged on the outer walls of the conveying pipes 4, used to deliver the water mist to the outside, increasing the diffusion area of ​​the water mist. The mounting frame 2 includes an adjusting structure that drives the two sets of conveying pipes 4 to move in opposite directions, and a flipping structure that drives the conveying pipes 4 to rotate. The adjusting structure adjusts the pipe spacing through mechanical linkage to control the coverage area of ​​the water mist, while the flipping structure adjusts the spray direction by rotating the pipes, achieving three-dimensional spatial coverage within the corridor space and improving dust suppression. It also includes an ultrasonic atomizing humidifier 1, which is existing technology. Ultrasonic atomization technology uses high frequency to vibrate liquid water into tiny droplets, thereby increasing the contact area with dust. Both conveying pipes 4 are connected to the ultrasonic atomizing humidifier 1 to guide the water mist into the feeding corridor for dust suppression. In actual operation, the ultrasonic atomizing humidifier 1 converts water into micron-sized water mist, which is then conveyed through the conveying pipes 4 to the nozzles 8 for spraying. The adjusting structure drives the two sets of conveying pipes 4 to move in opposite directions, adjusting the spray coverage width. The flipping structure drives the conveying pipes 4 to rotate around their axis, changing the angle of the nozzles 8. This ensures that the water mist evenly covers the dusty area of ​​the feeding corridor, adsorbing and settling the dust.

[0021] In some technical solutions of this utility model, the adjustment structure includes a mounting seat 9 installed inside the mounting frame 2. The mounting seat 9 is bolted to the middle of the mounting frame 2. A mounting shaft 12 is installed inside the mounting seat 9, and the mounting shaft 12 is integrally formed with the mounting seat 9. Two adjusting arms 10 are rotatably mounted on the mounting shaft 12. The two adjusting arms 10 are scissor-shaped. A push rod structure 11 is provided on the mounting seat 9. The body of the push rod structure 11 is connected to one of the adjusting arms 10, and the telescopic end of the push rod structure 11 is connected to the other adjusting arm 10. The free ends of both adjusting arms 10 are slidably connected to the conveying pipe 4 located on the same side. The push rod structure 11 is a pneumatic push rod or an electric telescopic rod, and the above structures are all prior art. When the telescopic end of the push rod structure 11 pulls one adjusting arm 10, its body pushes the other adjusting arm 10, thereby linking the two adjusting arms 10 to rotate synchronously in opposite directions around the mounting shaft 12, which in turn drives the conveying pipe 4 to move horizontally, realizing stepless adjustment of the pipe spacing. The mechanical linkage of the two adjusting arms 10 in the push rod structure 11 ensures symmetrical movement of the two pipes, avoiding spray overlap or omission.

[0022] In some technical solutions of this utility model, the flipping structure includes a pair of retainers 5, with two conveying pipes 4 rotatably mounted within the two retainers 5. The free ends of the two adjusting arms 10 are slidably connected to the retainers 5 on the same side. A motor connected to and driven by the conveying pipes 4 is installed within the retainers 5 to directly drive the conveying pipes 4 to rotate. When the adjusting arm 10 moves horizontally, its free end slides within the groove of the retainer 5, forcing the retainer 5 to drive the conveying pipe 4 to rotate around its own axis. The groove and the adjusting arm 10 form an inclined plane transmission mechanism, converting the horizontal displacement into a rotational torque of the pipe.

[0023] Preferably, a spiral groove 13 in the shape of a spiral is provided on the outer wall of the conveying pipe 4, and a slider 14 is provided on the adjusting arm 10 which is slidably set on the retainer 5. A guide groove adapted to the slider 14 is provided on the side wall of the retainer 5.

[0024] In some technical solutions of this utility model, a drainage pipe 6 is provided on the outer wall of the conveying pipe 4 and is connected to it. When the conveying pipe 4 is not in use, the residual condensate is automatically discharged through the drainage pipe 6. The setting of the drainage pipe also avoids low-temperature freezing or impurity deposition, extending its service life, and utilizes the principle of gravity drainage to set the drain outlet at the lowest point of the pipe.

[0025] In some technical solutions of this utility model, the input end of the ultrasonic atomizing humidifier 1 is connected to the external delivery pipe 4, and a solenoid valve is provided between the input end of the ultrasonic atomizing humidifier 1 and the external delivery pipe 4. The solenoid valve opens and closes according to the dust sensor signal, controlling the water circuit. An electrical signal drives the solenoid valve core to actuate, realizing automatic water circuit opening and closing. This achieves the purpose of saving water.

[0026] In some technical solutions of this utility model, a negative pressure fan 15 is installed inside the conveying pipe 4. The fan generates negative pressure inside the conveying pipe 4, accelerating the water mist from being ejected from the nozzle 8 and enhancing the diffusion distance. The negative pressure fan 15 increases the kinetic energy of the droplets ejected from the nozzle 8, increases the spray range, and improves the dust removal effect of this structure.

[0027] In some technical solutions of this utility model, a lifting structure 3 installed on the roof of the factory building is also included. The telescopic end of the lifting structure 3 is connected to the mounting frame 2. The lifting structure 3 (such as a hydraulic lifting column) drives the mounting frame 2 to lift as a whole, adjusting the height of the device. Different material stacking heights are available to optimize spraying efficiency. The conveying pipe 4 can also be lowered to the ground for easy maintenance. The lifting structure 3 is a traction-type, mechanical, or hydraulic linear lifting mechanism.

[0028] In some technical solutions of this utility model, a water collection groove is provided on the inner wall of the conveying pipe 4, with the horizontal height of one end of the water collection groove being higher than the horizontal height of the other end. Condensate on the inner wall of the pipe is guided to the drainage pipe 6 along the inclined water collection groove. The groove is designed as a slope with an inclination angle greater than 3°, utilizing gravity to guide the flow and thoroughly remove accumulated water from the pipe, preventing the growth of microorganisms. This prevents accumulated water from corroding the pipe or affecting the operation of the negative pressure fan 15.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
