Description

Technical Field

[0002] In mining operations, a large amount of dust is generated during the work of large machinery for drilling or excavating rock formations, which will affect the physical health of workers and is not conducive to environmental protection. Therefore, dust collectors are usually used in mining operations to handle dust, especially cylindrical dust collectors are often used.

[0003] However, the filter plates inside traditional cylindrical dust collectors usually need to be replaced or cleaned when the dust collector stops working. During the operation of the dust collector, the filter plates do not perform well in dust removal, which easily causes the filter plates to become blocked and the dust removal effect to be poor. In addition, traditional cylindrical dust collectors usually use nozzles to spray water for dust removal when in use, but the spraying of water inside the dust collector will damage the internal parts of the dust collector, seriously affecting the service life of the parts, and the water will cause the dust to gather together, further accelerating the blockage of the filter plates.

Detailed implementation manners

[0036] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0037] As Figures 1 - 12 shown, a mine barrel dust collector includes a base 1, the base 1 is fixedly connected with a main barrel 2, one end of the main barrel 2 is fixedly provided with a protective net 3, a driving mechanism 4 and a fixed frame 6 are arranged inside the main barrel 2, the output shaft of the driving mechanism 4 is fixedly connected with a fan blade 5, a filter plate 7 is arranged inside the fixed frame 6, and an impact dust removal structure 8 is arranged inside the main barrel 2;

[0038] The impact dust removal structure 8 includes two sliding plates 11 and a storage tray 12. The sliding plates 11 are fixedly connected with the inner side of the main barrel 2, the storage tray 12 is slidably connected with the main barrel 2 and the sliding plates 11. One end of the sliding plate 11 is fixedly provided with a bottom plate 13, and two first springs 14 are arranged between the bottom plate 13 and the storage tray 12. One side of the storage tray 12 is fixedly provided with a storage rack 15, two movable rods 16 are rotatably connected to the storage rack 15, one end of the movable rod 16 is fixedly connected with a first fixed frame 17, and a soft roller 18 is rotatably arranged inside the first fixed frame 17.

[0039] The impact dust removal structure 8 cooperates with the driving mechanism 4 and the fan blade 5 to knock off the dust accumulated on the surface of the filter plate 7, avoiding the dust continuously accumulating on the surface of the filter plate 7 and causing blockage of the filter plate 7, which affects the dust filtering efficiency. At the same time, the setting of the second spring 20 and the soft roller 18 enables the impact force to be buffered, avoiding hard contact between the soft roller 18 and the filter plate 7 and causing damage to the filter plate 7.

[0040] In this embodiment, the impact dust removal structure 8 further includes a driving component. The driving component includes a mounting plate 22, a second fixed frame 23 and a baffle 24. The mounting plate 22 and the second fixed frame 23 are both fixedly connected with the storage tray 12, the baffle 24 is rotatably connected with the storage tray 12, the baffle 24 is fixedly connected with an internal gear ring 26 through two connecting plates 25, a first motor 27 is arranged on one side of the mounting plate 22, the output shaft of the first motor 27 is fixedly connected with a small runner 28, a large runner 29 is rotatably connected to the second fixed frame 23, and the large runner 29 and the small runner 28 are connected by a belt 30. The large runner 29 is fixedly connected with a first gear 31, and the first gear 31 meshes with the internal gear ring 26.

[0041] The driving component cooperating with the impact dust removal structure 8 enables the baffle 24 to continuously block and expose the fan-shaped holes of the placement tray 12, and then cooperate with the driving mechanism 4 and the fan blade 5, so that the placement tray 12 continuously reciprocates outside the two sliding plates 11, which is beneficial to making the soft roller 18 continuously impact the filter plate 7, causing the dust on the surface of the filter plate 7 to fall off.

[0042] In this embodiment, two fan-shaped holes are provided on the outside of the placement tray 12, and two fan-shaped holes are provided on the outside of the baffle 24.

[0043] During the rotation of the baffle 24, the fan-shaped holes of the placement tray 12 can be blocked and exposed.

[0044] In this embodiment, a number of through holes are provided on the outside of the baffle 24, and the baffle 24 and the placement tray 12 are adaptively matched.

[0045] The arrangement of the through holes of the baffle 24 can effectively solve the potential safety hazard problem caused by the increase in the internal pressure of the main cylinder 2 when the baffle 24 completely blocks the fan-shaped holes of the placement tray 12.

[0046] In this embodiment, a dust removal protection structure 9 is provided on the outside of the main cylinder 2. The dust removal protection structure 9 includes a dust collection tank 32 and a fixing ring 38. The dust collection tank 32 is fixedly connected to the main cylinder 2 through penetration, the fixing ring 38 is fixedly connected to the main cylinder 2, a conveying paddle 33 is rotatably arranged on the inner side of the dust collection tank 32, one end of the conveying paddle 33 penetrates through the inner side of the main cylinder 2 and is fixedly connected to the output shaft of the second motor 34, and a discharge port 35 is fixedly connected to the outside of the dust collection tank 32 through penetration.

[0047] The dust removal protection structure 9 cooperating with the impact dust removal structure 8 can collect the dust blocked by the filter plate 7 into the dust collection tank 32, and at the same time, the dust inside the dust collection tank 32 can be transported through the conveying paddle 33 and finally discharged through the discharge port 35.

[0048] In this embodiment, a movable ring 39 is rotatably arranged on the inner side of the fixing ring 38. An external gear ring 40 is fixedly connected to the outside of the movable ring 39. A protective plate 41 is fixedly arranged on one side of the external gear ring 40, and the external gear ring 40 is meshed with a second gear 37. A connecting rod 36 is fixedly connected to one side of the second gear 37. One end of the connecting rod 36 penetrates through the dust collection tank 32 and is fixedly connected to the conveying paddle 33.

[0049] The cooperation of the second gear 37 and the external gear ring 40 enables the protective plate 41 to slowly rotate as the conveying paddle 33 rotates. On the one hand, the rotation of the protective plate 41 can prevent soil blocks from falling and causing blockage of the protective net 3, affecting the dust removal work of the dust collector. On the other hand, the slow rotation of the protective plate 41 will not interfere with the dust suction work of the fan blade 5.

[0050] In this embodiment, the protective plate 41 is composed of two S-shaped plates.

[0051] The protective plate 41 can prevent the blockage of the protective net 3.

[0052] In this embodiment, a secondary filtration structure 10 is provided at the other end of the main cylinder 2. The secondary filtration structure 10 includes a filter cylinder 42 and a filter cover 47. The filter cylinder 42 is connected to the main cylinder 2 through a plurality of bolt fasteners I 43. A water tank 44 is fixedly arranged outside the filter cylinder 42. A water inlet 45 is arranged outside the water tank 44, and a plurality of atomizing nozzles 46 are arranged inside the water tank 44.

[0053] The secondary filtration structure 10 cooperating with the impact dust removal structure 8 can further enhance the dust removal effect, so that the dust is removed twice. At the same time, it can avoid the influence of the water sprayed by the atomizing nozzles 46 on the internal parts of the main cylinder 2, and can separate the main cylinder 2 and the filter cylinder 42 into dry and wet parts. The filter cylinder 42 and the filter cover 47 are convenient for installation and disassembly, and can be assembled according to needs, improving the working adaptability of the dust collector.

[0054] In this embodiment, the filter cover 47 is connected to the filter cylinder 42 through a plurality of bolt fasteners II 48. The bolt fasteners I 43 and the bolt fasteners II 48 are both composed of bolts and nuts.

[0055] The bolt fasteners I 43 and the bolt fasteners II 48 can install and fix the filter cylinder 42 and the filter cover 47.

[0056] In this embodiment, the filter cylinder 42 and the atomizing nozzles 46 are connected through. The sizes of both ends of the filter cylinder 42 are the same, and the bolt fasteners I 43 and the bolt fasteners II 48 can be used interchangeably.

[0057] The atomizing nozzles 46 carry out spraying dust removal work inside the filter cylinder 42.

[0058] It should be noted that the present invention is a mine-used cylindrical dust collector. Before use, place the cylindrical dust collector in the required place, connect an external water pipe to the water inlet 45 to connect to a water source, and connect a device for receiving dust at the discharge port 35, so that it can reach the operating conditions for work;

[0059] When dust removal work needs to be carried out, start the drive mechanism 4, the first motor 27, and the second motor 34 to remove dust from the dust: the drive mechanism 4 acts on the fan blade 5 to rotate at a high speed to suck the dust near the protective net 3 into the inside of the main cylinder 2, so that the dust passes through the fan-shaped holes of the baffle 24, the fan-shaped holes of the placement tray 12, the filter plate 7, the filter cylinder 42, and the filter cover 47 in sequence. When the dust passes through the filter plate 7, it is filtered by the filter plate 7, and the dust particles are blocked by the filter plate 7. A small amount of dust is sprayed by the atomizing nozzles 46 when passing through the filter cylinder 42. Finally, the air blown out from the filter cover 47 has no dust;

[0060] The first motor 27 acts on the small runner 28 to drive the belt 30 to rotate. The belt 30 acts on the large runner 29 to rotate and drive the first gear 31 to rotate. The first gear 31 drives the internal gear ring 26 to perform meshing motion, causing the baffle 24 to rotate slowly. When the baffle 24 gradually covers the fan-shaped hole of the object placing plate 12, due to the strong wind generated by the fan blade 5 acting on the baffle 24 and the object placing plate 12, the object placing plate 12 slides towards the filter plate 7. During the sliding process of the object placing plate 12, the soft roller 18 impacts the filter plate 7. After the soft roller 18 contacts the filter plate 7, the two soft rollers 18 drive the corresponding movable rods 16 to move towards both sides, and at the same time, the two connecting arms 21 gradually open. During this process, the hard impact of the soft roller 18 on the filter plate 7 is avoided, and the impact force is buffered by the second spring 20. When the baffle 24 gradually exposes the fan-shaped hole of the object placing plate 12, the first spring 14 gradually loses pressure and begins to act on the object placing plate 12 to slide back, causing the soft roller 18 to move away from the surface of the filter plate 7. During the continuous rotation of the baffle 24, the fan-shaped hole of the object placing plate 12 is continuously exposed and closed, and the object placing plate 12 reciprocally slides outside the slide plate 11, causing the soft roller 18 to continuously impact the filter plate 7, so that the dust particles on the surface of the filter plate 7 continuously fall into the interior of the main cylinder 2. The dust inside the main cylinder 2 will eventually fall into the interior of the dust collection tank 32, and is transported by the conveying paddle 33 under the action of the second motor 34, and is discharged through the discharge port 35 into an external device for collecting dust;

[0061] During the process, since the atomizing nozzle 46 is arranged inside the filter cylinder 42, under the action of the high-speed rotation of the fan blade 5, the ash with dust is blown towards the filter cover 47 quickly and strongly. Therefore, the dust is first blocked by the filter plate 7, deposited inside the main cylinder 2 and collected inside the dust collection tank 32 and transported by the conveying paddle 33, while a small amount of dust is sprayed by the atomizing nozzle 46 to form water and flows out from the filter cover 47. At the same time, clean air is blown out, which can avoid the water sprayed by the atomizing nozzle 46 from affecting the parts inside the main cylinder 2, and at the same time enables the main cylinder 2 and the filter cylinder 42 to be dry and wet separated without interference;

[0062] In addition, when the atomizing nozzle 46 does not need to spray for secondary filtration, remove the first bolt fastener 43 and the second bolt fastener 48 to remove the filter cylinder 42 and the filter cover 47, and install the filter cover 47 on the main cylinder 2 through the first bolt fastener 43 or the second bolt fastener 48.
