Description

Technical Field

[0001] The utility model relates to the technical field of coal mine mine water purification, and specifically relates to a backwashing mechanism of a coal mine mine water purification device. Background Technique

[0002] Backwashing the mine water filtration device is to prevent the filter layer from being blocked by suspended matter or biofilm due to long-term filtration and restore its filtration performance. By flushing the filter layer with reverse water flow, the accumulated dirt is removed, and the filtration device is kept unobstructed and efficient. This can not only extend the service life of the filtration device, but also ensure the cleanliness and safety of the filtered water quality, laying a foundation for the in-depth treatment of mine water. Therefore, backwashing the mine water filtration device is an important measure to maintain its normal operation.

[0003] The utility model with the authorization publication number CN218608286U provides a device applied to the treatment of coal mine underground water, which belongs to the technical field of "coal mine mine water purification". The protected claims are: "Including a filtration chamber, which is arranged underground and is internally provided with a filter cylinder. The filter cylinder divides the interior of the filtration chamber into a filtration space inside the filter cylinder and a purification space outside the filter cylinder. The filtration chamber is provided with a water inlet corresponding to the filtration space; a neutralization chamber, which is arranged on the ground and is communicated with the purification space through a pipeline, and a water pump is arranged on the pipeline. By arranging the filtration chamber underground and the neutralization chamber on the ground, the device is arranged in a split manner, and the pipeline for conveying water to the ground is arranged between the filtration chamber and the neutralization chamber. When the underground water enters the filtration space through the water inlet, it needs to pass through the filter cylinder to enter the purification space to achieve filtration, and then is driven by the water pump into the pipeline. At this time, in the underground water, since it no longer contains large-particle impurities, it is not easy to cause great damage to the inner wall of the pipeline."

[0004] In this device, although the mine water can be filtered, it is not easy to backwash the filtration mechanism, and it is easy to cause blockage after long-term use. Therefore, we propose a backwashing mechanism of a coal mine mine water purification device. Content of the Utility Model

Detailed implementation manners

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1-5 shown, in this embodiment, a backwashing mechanism of a coal mine mine water purification device includes a cylinder body 1, a pipe body 2 and a backwashing assembly 3. The pipe body 2 is connected through and outside the cylinder body 1, and the backwashing assembly 3 is arranged inside the pipe body 2;

[0027] The backwashing assembly 3 includes a support block 301, a clamping tooth plate 303, a backwashing plate 306, a rotating shaft 307 and a power storage locking component 4; two support blocks 301 are fixedly connected to the inner top of the pipe body 2, and a spring 302 is fixedly connected to one side of each of the two support blocks 301; two clamping tooth plates 303 are respectively slidably connected to the inside of the pipe body 2, and a first moving tooth plate 304 is fixedly connected to the inside of each of the two clamping tooth plates 303. A connecting plate 305 is fixedly connected between the two first moving tooth plates 304, and one end of each of the two springs 302 is fixedly connected to one side of the connecting plate 305; the backwashing plate 306 is fixedly connected inside the connecting plate 305; the rotating shaft 307 is rotatably connected inside the pipe body 2, and a plurality of paddle plates 308 are fixedly connected to the outside of the rotating shaft 307. First gears 309 and second gears 310 are fixedly sleeved at both ends of the rotating shaft 307, and the two first gears 309 are respectively meshed and connected with the two first moving tooth plates 304; two power storage locking components 4 are respectively arranged on both sides inside the pipe body 2.

[0028] During specific implementation, the mine water is sent into the pipe body 2 through a water valve arranged inside the cylinder body 1, and then filtered through a plurality of filter plates 8. The filtered well water impacts the upper part of the backwashing assembly 3 along the slope 9, driving the plurality of paddle plates 308 to rotate clockwise. The plurality of paddle plates 308 then drive the rotating shaft 307 to rotate clockwise, and then drive the first gears 309 at both ends to rotate clockwise. The two first gears 309 then drive the two first moving tooth plates 304 to move, synchronously driving the two springs 302 to stretch and store power. At the same time, the first moving tooth plate 304 drives the clamping tooth plate 303 to move synchronously, and at the same time drives the power storage locking components 4 on both sides to operate. The power storage locking components 4 on both sides release the first moving tooth plates 304 that are caught during the process of being stretched and stored power by the springs 302, and then drive the backwashing plate 306 to return for backwashing, and cooperate with the plurality of paddle plates 308 rotating counterclockwise to perform backwashing and cleaning on the plurality of filter plates 8.

[0029] In addition, it should be noted that the telescopic rod 404 includes two rod bodies, which are slidably connected to each other. There is no need to set a damping structure between the two rod bodies. The two second movable tooth plates 402 rise and drive the two telescopic rods 404 to extend and retract. The two telescopic rods 404 can drive the two ratchet pawls 403 to rotate only after they are extended and retracted to their full length. The extension and retraction of the telescopic rod 404 provides time for the spring 302 to stretch and accumulate force. During the extension and retraction of the telescopic rod 404, the ratchet 403 is fixed and can only be driven to rotate after the telescopic rod 404 is extended and retracted to its full length. Vice versa, during the time when the telescopic rod 404 is extended and retracted to its full length, the first movable tooth plate 304 moves. The extension and retraction of the telescopic rod 404 provides time for the movement of the first movable tooth plate 304. When the telescopic rod 404 is extended and retracted to its full length, the ratchet pawl 403 is also driven to engage the locking tooth plate 303, and the cycle repeats.

[0030] Furthermore, two sliders 5 are fixedly connected to the bottom end of the recoil plate 306 . Both sliders 5 are slidably connected to the inner bottom surface of the tube body 2 . The sliders 5 are provided to provide position limiting support when the recoil plate 306 moves.

[0031] Furthermore, a plurality of circular holes 6 are provided in the plurality of paddle plates 308, and a plurality of water holes 7 are provided in the recoil plate 306. The circular holes 6 and the water holes 7 are provided for the passage of mine water.

[0032] Furthermore, a plurality of filter plates 8 are fixedly connected in the pipe body 2 , and the mine water flows into the recoil assembly 3 after being filtered by the plurality of filter plates 8 .

[0033] Furthermore, a slope 9 is fixedly provided in the pipe body 2 to raise the water flow and impact the upper part of the recoil assembly 3, thereby driving the plurality of paddles 308 to rotate clockwise.

[0034] Embodiment 2

[0035] like Figure 3 and Figure 5 As shown, the force storage locking assembly includes a third gear 401, a second movable tooth plate 402 and a pawl 403; the two third gears 401 are respectively rotatably connected to the inner wall of the tube body 2, and the two third gears 401 are respectively meshed with the two second gears 310; the two second movable tooth plates 402 are respectively slidably connected to the inner wall of the tube body 2; the two pawls 403 are respectively rotatably connected to the inner wall of the tube body 2, one end of the two pawls 403 is rotatably connected to the telescopic rod 404, and the bottom ends of the two telescopic rods 404 are respectively rotatably connected to the inner sides of the two second movable tooth plates 402.

[0036] During specific implementation, the rotating shaft 307 rotates clockwise, synchronously driving the second gears 310 on both sides to rotate clockwise, thereby driving the two third gears 401 to rotate counterclockwise, and then driving the two second movable tooth plates 402 to rise. The rising of the two second movable tooth plates 402 drives the two telescopic rods 404 to extend and retract. After the two telescopic rods 404 are extended and retracted to the right position, they drive the two ratchet claws 403 to rotate. The two ratchet claws 403 are released from the engaged state with the locking tooth plates 303. The locking tooth plates 303 are released, and the force-accumulating springs 302 are released. The springs 302 immediately rebound and return to their original positions, driving the recoil plate 306 to return and recoil. At the same time, the two first movable tooth plates 304 return to their original positions, driving the multiple paddle plates 308 to rotate counterclockwise. The recoil plate 306 cooperates with the multiple paddle plates 308 rotating counterclockwise to perform recoil cleaning on the multiple filter plates 8.

[0037] In addition, it should be noted that when the recoil plate 306 returns to its position and recoils, the return of the first movable tooth plate 304 will drive the third gear 401 to rotate clockwise after linkage, and the second movable tooth plate 402 will descend, thereby driving the telescopic rod 404 to extend into place, and immediately driving the pawl 403 to rotate back to its position, engaging the first movable tooth plate 304, and repeating the cycle. The continuous impact of mine water will continuously drive the recoil assembly 3 to return to its position and recoil. It should be noted that the spring 302 is a high-elasticity spring, and the elasticity of the spring 302 is sufficient to resist the impact of the water flow.

[0038] In addition, in order to avoid the spring 302 from repeatedly operating and losing its elastic potential energy, the valve body in the cylinder 1 needs to intermittently release the mine water for filtering and then recoil.

[0039] Working principle: First, the mine water is sent into the pipe body 2 through the water valve arranged inside the cylinder body 1, and then filtered through multiple filter plates 8. The filtered mine water impacts the upper part of the backflush assembly 3 along the slope 9, driving multiple paddle plates 308 to rotate clockwise. The multiple paddle plates 308 then drive the rotating shaft 307 to rotate clockwise, and then drive the first gears 309 at both ends to rotate clockwise. The two first gears 309 then drive the two first moving toothed plates 304 to move, synchronously driving the two springs 302 to stretch and store energy. At the same time, the first moving toothed plate 304 drives the positioning toothed plate 303 to move synchronously, driving the energy storage locking components 4 on both sides to operate. Specifically, the rotating shaft 307 rotates clockwise, synchronously driving the second gears 310 on both sides to rotate clockwise, then driving the two third gears 401 to rotate counterclockwise, and then driving the two second moving toothed plates 402 to rise. The rising of the two second moving toothed plates 402 drives the two telescopic rods 404 to expand and contract. After the two telescopic rods 404 expand and contract in place, they drive the two pawls 403 to rotate, and the two pawls 403 are released from the clamped state with the positioning toothed plate 303. When the positioning toothed plate 303 is released, the spring 302 storing energy is released, and the spring 302 immediately rebounds to its original position, driving the backflush plate 306 to return for backflushing. At the same time, the two first moving toothed plates 304 return to their original positions, driving the multiple paddle plates 308 to rotate counterclockwise. The backflush plate 306 and the multiple paddle plates 308 rotating counterclockwise cooperate to perform backflush cleaning on the multiple filter plates 8.
