Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in coal mining, specifically to a wet dust removal device for coal mining. Background Technology

[0002] Wet dust collectors for coal mining are used in coal mining operations to capture and settle dust using water or liquid. They reduce dust concentration during tunneling and coal mining by using spraying and washing to make the dust settle after contact with the liquid. The system consists of water supply, spraying, and control systems.

[0003] Utility model patent CN222615381U discloses a wet dust removal device for coal mining, including an assembly cylinder, a fixed base, a rotating bearing, a water inlet pipe, a sealing ring, a sealing cover, and a control component. The assembly cylinder is connected to the fixed base via the rotating bearing. Water is introduced through the water inlet pipe to create water pressure. The control component has an assembly tube inside the assembly window. An atomizing head on one side sprays water mist under water pressure. Rotating the rotating wheel enables rotary atomization spraying, allowing the water mist to cover the space more comprehensively, increasing the dust contact area, and improving the dust adhesion to the water mist, thus enhancing the dust removal effect. The rotating roller in the mounting groove on the inner wall of the assembly window is fitted with coil springs at both ends to lock and fix the assembly tube, ensuring the stability of the atomizing head's spray direction and ensuring stable dust removal performance. With the help of the rotating roller and the limiting seat structure, the spray area of ​​the atomizing head can be easily adjusted according to the actual situation, adapting to different mining areas and dust distributions, improving the adaptability and practicality of the device.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing dust removal devices utilize atomizing heads to spray mist for dust removal. However, when the dust removal device stops, residual water stains on the nozzle surface form a wet interface. Coal mining is conducted in a dusty environment, where suspended dust particles in the air quickly adhere to the surface, especially in delicate areas such as the atomizing holes of the atomizing head. After the dust mixes with the moisture, it gradually dries and solidifies, causing blockage of the atomizing holes. This not only requires frequent cleaning but also affects the subsequent efficiency of the dust removal device and reduces its dust removal effect. Utility Model Content

[0018] I. This utility model, by setting up a dust removal device body, assembly pipe, atomizing head, adjustment and protection components, and connecting dust removal components, etc., uses a protective ring to protect the outside of the assembly pipe and the air extraction effect of the exhaust fan and connecting pipe to protect the atomizing head when it is not working. At the same time, after the machine is stopped, the exhaust fan extracts the dust-containing air from the protective ring.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] See attached document Figure 1-5A wet dust removal device for coal mining includes: a dust removal device body 1, an assembly pipe 2, and an atomizing head 3. The outer side of the dust removal device body 1 is rotatably connected to one end of the assembly pipe 2, and the surface of the assembly pipe 2 is connected to the atomizing head 3. An adjustment and protection assembly 4 is fixedly connected to the outer side of the dust removal device body 1. The adjustment and protection assembly 4 includes a protection ring 41. Several sets of insertion slots 42 are opened on the outer side of the protection ring 41. A movable rod 43 is movably inserted into the inside of the insertion slots 42. A movable ring 44 is fixedly connected to the outer side of the movable rod 43. The movable ring 44 is located on the protective ring. On the surface of 41, a connecting dust removal assembly 5 is fixedly connected to the top of the dust removal device body 1. The connecting dust removal assembly 5 includes a fixed box 51, and several sets of connecting pipes 52 are connected to the outside of the fixed box 51. An exhaust fan 53 is connected to the top of the fixed box 51. The other end of the connecting pipe 52 is connected to the top of the protective ring 41. The protective ring 41 in the adjusting protective assembly 4 on the outside of the dust removal device body 1 can protect the outside of the assembly pipe 2 and the atomizing head 3. At the same time, the insertion groove 42, the moving rod 43 and the moving ring 44 on the outside of the protective ring 41 cooperate with each other to... Adjusting the moving ring 44 facilitates the normal use of the atomizing head 3. The dust removal component 5 is connected to the exhaust fan 53 via the fixing box 51 and connecting pipe 52. After use, the air inside the protective ring 41 can be extracted to prevent dust in the air inside the protective ring 41 from adhering to the atomizing head 3 and clogging it. A slider 6 is fixedly connected to the inner side of the moving rod 43, and an electromagnetic ring 7 is magnetically connected to the outer side of the slider 6. A damping spring 8 is fixedly connected to the inner side of the slider 6, and the other end of the damping spring 8 is fixedly connected to the inner side of the inner wall of the insertion slot 42. The electromagnetic ring 7 is fixedly connected to... Inside the protective ring 41, the slider 6 on the inner side of the moving rod 43 is magnetically connected to the electromagnetic ring 7 inside the protective ring 41. When the electromagnetic ring 7 is energized, it can attract the slider 6 to move the moving rod 43, thereby causing the moving ring 44 to move and expose the spraying groove 9. When the power is off, the damping spring 8 pulls the slider 6 to reset, causing the moving rod 43 to insert into the insertion groove 42 and drive the moving ring 44 to reset, covering the spraying groove 9. Through the synergistic effect of the electromagnetic ring 7 and the damping spring 8, the moving ring 44 can be easily extended, retracted and positioned on the surface of the protective ring 41, ensuring the stability of the device after adjustment.

[0031] Several spray grooves 9 are provided on the outer side of the protective ring 41. A rubber ring 10 is fixedly connected to the inner side of the moving ring 44. The spray grooves 9 on the outer side of the protective ring 41 allow the water mist sprayed by the atomizing head 3 to be sprayed out normally. When the moving ring 44 seals the spray grooves 9, the rubber ring 10 on the inner side of the moving ring 44 is in close contact with the surface of the protective ring 41, which can seal the gaps to prevent dust from entering and improve the applicability of the device in dusty environments. A cleaning ring 11 is fixedly connected to the inner side of the rubber ring 10. The cleaning ring 11 is slidably connected to the surface of the protective ring 41. When the inner cleaning ring 11 moves with the moving ring 44, it can clean the sliding position around the spray tank 9, preventing the long-term accumulation of dust and solidified matter from affecting the movement of the moving ring 44. The top of the fixed box 51 is fixedly connected to the protective box 12, and the exhaust fan 53 is located inside the protective box 12. The protective box 12 on the top of the fixed box 51 encloses the exhaust fan 53, which can isolate dust, water vapor and other impurities in the coal mining environment, reduce the corrosion and wear of impurities on the internal parts of the exhaust fan 53, and extend the service life of the exhaust fan 53.

[0032] A tension spring 13 is embedded in the top of the protective box 12. A sealing plate 14 is fixedly connected to the other end of the tension spring 13. The bottom of the sealing plate 14 is movably connected to the top of the protective box 12. One end of the tension spring 13 inside the protective box 12 is connected to the sealing plate 14. Under normal conditions, the tension spring 13 pulls the sealing plate 14 tightly against the top of the protective box 12, forming a sealed structure to prevent dust from entering the protective box 12. When the exhaust fan 53 starts cleaning the inside of the protective ring 41, the output of the exhaust fan 53 blows air out, lifting the sealing plate 14 and expelling the dust with the airflow. When the exhaust fan 53 stops, the tension spring 13 pulls the sealing plate 14 back to its original position, effectively sealing the top of the protective box 12. An inclined block 15 is fixedly connected to the bottom of the sealing plate 14, and a baffle 16 is fixedly connected to the outer side of the bottom of the sealing plate 14. The baffle 16 is connected to the top of the protective box 12. The sliding connection allows the inclined block 15 at the bottom of the sealing plate 14 to guide concentrated airflow. The baffle 16 is slidably connected to the top of the protective box 12, which can effectively limit the movement trajectory of the sealing plate 14 and improve the stability of the sealing plate 14 when resetting. A moving block 17 is installed on the outside of the assembly tube 2, and a connecting groove 18 is opened on the outside of the moving ring 44. A sealing ring 19 is fixedly connected inside the connecting groove 18. The surface of the moving block 17 is located inside the connecting groove 18. The moving block 17 on the outside of the assembly tube 2 is embedded in the connecting groove 18 of the moving ring 44. The sealing ring 19 in the connecting groove 18 can prevent external dust from entering through the connecting groove 18. At the same time, the cooperation between the moving block 17 and the connecting groove 18 allows the existing assembly tube 2 to rotate normally to adjust the spray trajectory, which is convenient for adjusting the position of the atomizing head 3 according to the dust removal requirements.

[0033] Working principle: When in use, the dust removal device body 1 is started, and the assembly tube 2 and atomizing head 3 start to work. At this time, the electromagnetic ring 7 in the adjustment protection component 4 is energized, and the magnetic attraction of the slider 6 drives the moving rod 43 to move outward, so that the moving ring 44 slides on the surface of the protective ring 41 and exposes the spray groove 9, ensuring that the water mist sprayed by the atomizing head 3 can normally cover the dust removal area through the spray groove 9. At the same time, the moving block 17 on the outside of the assembly tube 2 cooperates with the connecting groove 18 of the moving ring 44, allowing the assembly tube 2 to rotate and adjust the spray trajectory according to the dust removal requirements, so that the position and spray direction of the atomizing head 3 can be flexibly adjusted.

[0034] When dust removal stops, the electromagnetic ring 7 is de-energized, and the damping spring 8, with its restoring force, pulls the slider 6 to move inward toward the insertion slot 42, causing the moving ring 44 to reset and cover the spray trough 9. At this time, the rubber ring 10 on the inner side of the moving ring 44 is tightly attached to the surface of the protective ring 41, sealing the gap to prevent dust from contacting the atomizing head 3. During the movement of the moving ring 44, the cleaning ring 11 on the inner side of the rubber ring 10 simultaneously wipes the sliding position around the spray trough 9 to remove solidified dust and prevent its accumulation from affecting the normal sliding of the moving ring 44. At the same time, the exhaust fan 53 starts, and the exhaust fan is connected to the connecting pipe 52 to remove the dust. Dust-laden air in the protective ring 41 is drawn into the fixed box 51 and then discharged by the exhaust fan 53. When the exhaust fan 53 is working, the air force pushes the sealing plate 14 upward, the tilting block 15 guides the air force to be discharged in a concentrated manner, and the baffle 16 restricts the movement trajectory of the sealing plate 14 to ensure smooth dust discharge. When the exhaust fan 53 stops working, the tension spring 13 pulls the sealing plate 14 to reset and reseal the top of the protective box 12 to prevent dust from entering the interior of the protective box 12 where the exhaust fan 53 is located. Thus, through the dual mechanism of physical protection and airflow cleaning, the adhesion of dust on the surface of the atomizing head 3 is effectively reduced, and the atomizing hole is prevented from being blocked.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
