Description

Technical Field

[0002] Mineral resource mining refers to the mining of solid metal and non-metal deposits, including open-pit mining of surface ore bodies and shallow ore bodies, as well as underground mining of blind mines and deep ore bodies. Among them, metal ores, as the main raw materials of the smelting industry, provide the material basis for the refining of various metals. From common iron and copper to relatively rare precious metals, all depend on the mining and processing of metal ores.

[0003] In the prior art, Chinese utility model patent with publication number CN217462232U discloses an explosion-proof dust removal device for mining. Although the above-mentioned existing technology can degrade and absorb combustible dust and flammable and explosive gases in the underground mining environment, in actual use, since the dust generation points in the mine are not evenly distributed but scattered in various corners of the working face, the fixed-direction nozzles and dust suction heads cannot achieve all-round coverage. The effect on dust accumulation areas on the side, above or in other corners of the device is limited. To deal with new dust generation points, the entire device must be moved frequently, resulting in a slow response speed and greatly affecting the timeliness and efficiency of dust removal. In view of this, we propose an explosion-proof dust removal device for mining to solve the above problems. Utility Model Content

[0013] Compared with the prior art, this utility model provides an explosion-proof dust removal device for mineral mining, which has the following beneficial effects:

[0014] 1. The mining operation adopts an explosion-proof dust removal device. Through the cooperation between the drive component, swing component and transmission component, the dust suction head and spray head can rotate in the horizontal direction and swing in the vertical direction at the same time. This allows the spraying and dust suction range to cover a larger working area around the device, effectively avoiding the dust removal blind spot problem caused by the fixed direction of the spray head and dust suction head. There is no need to move the entire device base, which significantly improves the dust removal coverage and efficiency.

Through the cooperation of structures such as sliding plates, synchronous plates, corrugated pipes and dust covers, the connector can be stored inside the device when not in operation, and the protective cover can be lowered to protect it. This effectively prevents dust and debris in the harsh environment of the mine from adhering to or clogging the dust suction port and spray head, and also avoids damage caused by accidental collisions. This ensures the reliability and working effect of the equipment when it is restarted, and reduces the long-term maintenance cost of the equipment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 This utility model provides a technical solution: an explosion-proof dust removal device for mineral mining, including a base 1, a horizontal plate 2 on the upper side of the base 1, a fixing block 3 fixedly connected to the upper surface of the horizontal plate 2, a top plate 4 fixedly connected to the upper surface of the fixing block 3, and two connectors 5 between the top plate 4 and the fixing block 3, and between the fixing block 3 and the horizontal plate 2. The two connectors 5 on the upper side are used to adsorb dust in the working environment, and the two connectors 5 on the lower side are used to spray water mist to reduce dust. Since the upper surface of the horizontal plate 2 and the upper surface of the fixing block 3 have the same structure, the following description focuses on the structure of the upper side of the fixing block 3. The upper surface of the fixing block 3 is fixed Four fixed plates 6 are connected, and the interior of each fixed plate 6 is hollow. Each fixed plate 6 has a transmission component inside. Since the multiple transmission components have the same structure, the following description focuses on one transmission component. A rotating rod 15 is rotatably connected between two adjacent fixed plates 6. A connecting component is provided on the outside of the rotating rod 15. A connector 5 is located between two adjacent fixed plates 6. A connecting tube 7 is fixedly sleeved on the outside of the rotating rod 15, and a flexible tube communicating with its interior is provided on the surface of each connecting tube 7. A corrugated pipe 8 is provided between the connecting tube 7 and the connector 5. A drive component and a swing component are provided on the upper surface of the base 1.

[0026] The connecting assembly includes two synchronous plates 16, both of which are fixedly sleeved on the outside of the rotating rod 15 and located on both sides of the connecting pipe 7. Sliding plates 17 are slidably sleeved inside each of the two synchronous plates 16. The connector 5 is fixedly connected between the two sliding plates 17. The rotation of the rotating rod 15 can drive the rotation of the synchronous plates 16 and the sliding plates 17, and the rotation of the sliding plates 17 can drive the movement of the connector 5, thereby enabling the connector 5 to spray or remove dust at different heights.

[0027] Two positioning grooves 18 are provided on the surface of the sliding plate 17. A positioning rod 19 is movably sleeved inside the synchronous plate 16. The positioning rod 19 is adapted to the two positioning grooves 18 respectively. By moving the positioning rod 19 out of the synchronous plate 16, the sliding plate 17 can slide inside the synchronous plate 16. Then, the positioning rod 19 can be inserted into the other positioning groove 18 to fix the position of the connector 5. When the connector 5 moves, the bellows 8 will be stretched or shortened accordingly.

[0028] The transmission assembly includes a toothed plate 10, which is slidably connected inside the fixed plate 6 and slides through the fixed plate 6. The two ends of the rotating rod 15 respectively rotate through the interior of the two fixed plates 6. The rotating rod 15 is fixedly fitted with a transmission gear 9 inside the fixed plate 6. The transmission gear 9 and the toothed plate 10 are meshed together. The ends of the two adjacent toothed plates 10 located outside the fixed plate 6 are fixedly connected to a connecting plate 14. A T-shaped rod 13 is fixedly connected to the surface of the connecting plate 14. The movement of the T-shaped rod 13 can drive the movement of the connecting plate 14, which in turn drives the movement of the toothed plate 10. The movement of the toothed plate 10 can drive the rotation of the transmission gear 9, which in turn drives the rotation of the rotating rod 15.

[0029] The swing assembly includes a fixed rod 24, which is fixedly connected to the upper surface of the base 1. The fixed rod 24 rotates through the horizontal plate 2 and the fixed block 3 in sequence. Two protrusions 11 are fixedly sleeved on the outside of the fixed rod 24. The two protrusions 11 are located between the horizontal plate 2 and the fixed block 3 and between the fixed block 3 and the top plate 4, respectively. A T-shaped groove 12 is opened on the surface of the protrusion 11, and a T-shaped rod 13 is slidably connected inside the T-shaped groove 12.

[0030] The drive assembly includes a gear ring 25, which is rotatably connected to the upper surface of the base 1. The gear ring 25 is fixedly connected to the horizontal plate 2. The upper surface of the base 1 is also rotatably connected to a drive gear 26 via a shaft. A motor is also matched with the drive gear 26. The motor is started by an external controller to drive the drive gear 26 to rotate slowly, which in turn drives the gear ring 25 to rotate. The rotation of the gear ring 25 drives the horizontal plate 2 to rotate, which in turn drives the fixed block 3 and the top plate 4 to rotate slowly together. Since the fixed rod 24 cannot rotate, the T-shaped rod 13 will slide inside the T-shaped groove 12. When the T-shaped rod 13 slides to the protrusion of the protrusion 11, it will push the connecting plate 14 away. When the T-shaped rod 13 slides to the recess of the protrusion 11, it will pull the connecting plate 14 closer, thereby realizing the reciprocating movement of the connecting plate 14. Finally, each connector 5 can swing up and down during the slow rotation.

[0031] A protective cover 20 is slidably fitted onto the outside of the fixed block 3. A through groove 21 is formed on the surface of the protective cover 20. Two connecting ears 22 are fixedly connected to the surface of the protective cover 20. Similarly, two connecting ears 22 are fixedly connected to the surface of the top plate 4. A threaded rod 23 is rotatably connected to the upper surface of the connecting ears 22 on the front surface of the protective cover 20. The connecting ears 22 on the front surface of the top plate 4 are threaded onto the outside of the threaded rod 23. A guide rod is fixedly connected to the surface of the connecting ears 22 on the rear side of the protective cover 20. The top plate 4 is slidably fitted onto the outside of the guide rod via the rear connecting ears 22. By rotating... The threaded rod 23 can move the protective cover 20. When the device is idle, the connector 5 can be retracted into the device with the help of the sliding plate 17 and the synchronous plate 16, and the bellows 8 is in a retracted state. Then the protective cover 20 is lowered. At this time, the solid part of the protective cover 20 will block the cavity between the horizontal plate 2, the fixed block 3 and the top plate 4, thereby effectively preventing dust in the working environment from adhering to the surface of the connector 5. When it is needed later, the protective cover 20 is lowered and the through groove 21 is aligned with the cavity between the horizontal plate 2 and the fixed block 3.

[0032] The top plate 4 is provided with a first diversion pipe 27, which penetrates into the interior of the top plate 4 and is connected to the flexible hoses on the surfaces of the two connecting pipes 7 on the lower side. The side wall of the fixing block 3 is provided with a second diversion pipe 28, which penetrates into the interior of the fixing block 3 and is connected to the flexible hoses on the surfaces of the two connecting pipes 7 on the lower side. The surface of the protective cover 20 is also provided with a movable groove for sliding outside the second diversion pipe 28. The external fan and water pipe are connected to the first diversion pipe 27 and the second diversion pipe 28 respectively to facilitate subsequent dust collection and dust suppression.

[0033] The connection method between the first diversion pipe 27 and the second diversion pipe 28 and the flexible hose on the surface of the connecting pipe 7 is a well-known technique to those skilled in the art, and therefore will not be described in detail here.

[0034] In the above embodiment, the maximum rotation angle of the structure such as the horizontal plate 2, the fixing block 3 and the top plate 4 is about 180 degrees, so as to maximize the dust collection and dust reduction area while effectively avoiding the situation where the external pipes are entangled with the first diversion pipe 27 and the second diversion pipe 28.

[0035] Working principle:

[0036] The explosion-proof dust removal device used in this mining operation operates by starting the motor via an external controller, which drives the drive gear 26 to rotate slowly. This rotation of the gear ring 25, in turn, drives the horizontal plate 2 to rotate. The rotation of the horizontal plate 2, in turn, drives the fixed block 3 and the top plate 4 to rotate slowly together. Since the fixed rod 24 cannot rotate, the T-shaped rod 13 slides inside the T-groove 12. When the T-shaped rod 13 slides to the protrusion of the protrusion 11, it pushes the connecting plate 14 further away. When the T-shaped rod 13 slides to the recess of the protrusion 11, it pushes the connecting plate 14 further away. 14 is pulled closer, thereby realizing the reciprocating movement of the connecting plate 14. The movement of the connecting plate 14 can drive the movement of the toothed plate 10. The movement of the toothed plate 10 can drive the rotation of the transmission gear 9. The rotation of the transmission gear 9 can drive the rotation of the rotating rod 15. The rotation of the rotating rod 15 can drive the rotation of the synchronous plate 16 and the sliding plate 17. The rotation of the sliding plate 17 can drive the movement of the connector 5, thereby enabling the connector 5 to spray or remove dust at different heights. Finally, each connector 5 can swing up and down during the slow rotation process.

[0037] Additionally, when the device is restricted, the operator can move the positioning rod 19 out of the synchronous plate 16. At this time, the sliding plate 17 can slide inside the synchronous plate 16. Then, the positioning rod 19 can be inserted into another positioning groove 18 to retract the connector 5 into the device. When the connector 5 moves, the bellows 8 will shorten accordingly. Then, by rotating the threaded rod 23, the protective cover 20 can be moved. At this time, the solid part of the protective cover 20 will block the cavity between the horizontal plate 2, the fixing block 3 and the top plate 4, thereby effectively preventing dust in the working environment from adhering to the surface of the connector 5. When it is needed later, the protective cover 20 can be lowered and the through groove 21 can be aligned with the cavity between the horizontal plate 2 and the fixing block 3.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
