One end of the first scraper is fixedly connected to one end of the first spring. The other end of the first spring is fixedly connected to the guide plate.

[0012] The separation mechanism is installed inside the separation tank to separate the water and mud from the sludge discharged from the first channel.

[0013] This invention provides a composite coal mine water underground high-efficiency sedimentation device, wherein the separation mechanism includes a rotating drum, a separation screen, a second scraper, and a sludge discharge pipe;

[0014] The output shaft of the first motor is fixed coaxially with the rotating drum. The rotating drum is fixed coaxially with one end of the separating screen.

[0021] The present invention discloses a composite coal mine water well water high-efficiency sedimentation device that differs from the prior art in that: 1.

The external circulation of high-density medium in the front-end mixing zone ensures the solid concentration in the flocculation zone, improves the flocculation capacity of suspended solids, and makes the formed flocs more uniform and dense. The sedimentation zone is equipped with inclined tube packing to increase the sedimentation area and greatly improve the coagulation and sedimentation effect and treatment effect.

[0022] 2. Magnetic flocculation technology is adopted. Magnetic powder is added to the mixing zone, and the speed and rotation mode of the mixing agitator are increased. The magnetic powder acts as the flocculation nucleus, which causes non-magnetic suspended matter to combine with the magnetic powder under the combined action of coagulant (PAC) and coagulant aid (PAM), forming a "magnetic composite" with magnetic powder as the core. These "magnetic composites" attract each other under the action of magnetic field force, forming flocs with large particle size and high density, increasing the collision opportunity, accelerating the settling speed of flocs in the sedimentation zone, effectively shortening the hydraulic residence time in the sedimentation zone and increasing its surface load.

[0023] 3. Considering the variability of underground coal mining faces and the relatively small underground space, high-density sedimentation, magnetic flocculation, and magnetic separation coupling technologies are adopted, resulting in a small-sized sedimentation device with a small footprint and a simple and compact design.

[0024] 4. This high-efficiency sedimentation device features high suspended solids removal efficiency, strong safety and explosion-proof function, high degree of automation, low engineering cost, reliable operation and low cost, and simple operation and maintenance.

[0035] like Figures 1-7 As shown, the present invention discloses a composite coal mine water underground high-efficiency sedimentation device, comprising a sedimentation tank 101, support legs 102, a sedimentation mechanism 200, and a separation mechanism 300, characterized in that:

[0036] The bottom of the sedimentation tank 101 is fixed with a plurality of the support legs 102, and the sedimentation mechanism 200 is installed at the bottom of the sedimentation tank 101;

[0037] The sedimentation mechanism 200 includes a first motor 201, a first gear ring 202, a first magnetic rod 203, a mud-sliding bucket 204, a first bevel gear 205, a second gear ring 206, a first guide hole 207, a guide rod 208, a guide plate 209, a first scraper 210, a first spring 211, a guide plate 212, a first channel 213, a first pin 214, a guide groove 215, a separation bucket 216, and a drain pipe 217.

[0038] The first motor 201 is fixedly connected to the sedimentation tank 101. The output shaft of the first motor 201 is drivenly connected to the first gear ring 202. The first gear ring 202 is rotatably and sealedly connected to the bottom of the sedimentation tank 101. One end of the first magnetic rod 203 is mounted on the first gear ring 202 through a bearing. The other end of the first magnetic rod 203 is mounted on the top of the mud-sliding bucket 204 through a universal joint. The mud-sliding bucket 204 is fixedly connected to the sedimentation tank 101. The first magnetic rod 203 is coaxially fixed to the first bevel gear 205. The first bevel gear 205 meshes with the second gear ring 206. The second gear ring 206 is coaxially fixed to the bottom of the mud-sliding bucket 204.

[0039] The first gear ring 202 has a plurality of first guide holes 207 evenly opened in the circumferential direction. The first guide rod 208 is disposed in the first guide hole 207 and moves along it. One end of the guide rod 208 is fixedly connected to the guide plate 209. One end of the first scraper 210 is disposed in the guide plate 209 and moves along it. One end of the first scraper 210 is fixedly connected to one end of the first spring 211. The other end of the first spring 211 is fixedly connected to the guide plate 209. The other end of the first scraper 210 overlaps with the outer surface of the mud-sliding bucket 204.

[0040] The other end of the guide rod 208 is fixedly connected to the first pin 214. The first pin 214 is disposed in the guide groove 215 and moves along it. The guide groove 215 is opened on the outer circumferential surface of the separation tank 216. The separation tank 216 is fixedly connected to the sedimentation tank 101. The bottom of the separation tank 216 is fixedly connected to one end of the drain pipe 217 and communicates with it.

[0041] The first toothed ring 202 is fixedly connected to the plurality of guide plates 212 along its circumference, and the bottom of the sedimentation tank 101 is fixedly connected to the plurality of the first channels 213 along its circumference and communicates with them.

[0042] The separation mechanism 300 is installed inside the separation tank 216 to separate the water and mud in the sludge discharged from the first channel 213.

[0043] The sedimentation tank 101 of this invention contains flocculated precipitate mixed with magnetic powder. The first magnetic rod 203 adsorbs the precipitate in the sedimentation tank 101 onto the surface of the mud-sliding bucket 204, and it slides down the mud-sliding bucket 204 to the bottom of the sedimentation tank 101. It is then discharged outward through the first channel 213 into the separation mechanism 300, where the separation mechanism 300 further separates water and mud. This method greatly improves the efficiency of mine water sedimentation and separation, enabling the separation of precipitates in the mine water in the shortest possible time, saving time and costs. In addition, the magnetic powder in the precipitate discharged through the separation mechanism 300 can be further recovered, thereby reducing the cost of use.

[0044] In this configuration, the first motor 201 drives the first magnetic rod 203 to rotate around the inner surface of the mud-sliding bucket 204. Through the mutual attraction between the first magnetic rod 203 and the magnetic powder in the flocculated sediment of the settling tank 101, the magnetic powder in the settling tank 101 carries the flocculated sediment and adheres to the outer surface of the mud-sliding bucket 204. Furthermore, during the rotation of the first gear ring 202, the guide rod 208 rotates synchronously. Through the configuration of the first pin 214 and the guide groove 215, the guide rod... The up-and-down movement of rod 208, along with the overlap between the first scraper 210 and the outer surface of the mud-sliding bucket 204, scrapes the sludge on the outer surface of the mud-sliding bucket 204 downwards. The sludge is then discharged outwards to the top of the first channel 213 by the rotation of the guide plate 212 at the bottom of the sedimentation tank 101, and slides downwards along the first channel 213 into the separation mechanism 300. The sludge is then separated by the separation mechanism 300, leaving it inside. The separated water is discharged outwards through the drain pipe 217.

[0045] For further explanation of the present invention, see Figure 4 ,

[0046] The separation mechanism 300 includes a rotating drum 301, a separation screen 302, a second scraper 303, and a sludge discharge pipe 304;

[0047] The output shaft of the first motor 201 is coaxially fixed with the rotating drum 301. The rotating drum 301 is coaxially fixed with one end of the separating screen 302. The other end of the separating screen 302 is rotatably sealed to 316. The bottom of the separating screen 302 is connected and communicates with the other end of the first channel 213. The top of the separating screen 302 overlaps with a plurality of second scraper blades 303. The plurality of second scraper blades 303 are fixedly connected to one end of the sludge discharge pipe 304. The sludge discharge pipe 304 communicates with the inner cavity of the separating screen 302. The sludge discharge pipe 304 is fixedly connected to the sedimentation tank 101.

[0048] In this invention, the sludge discharged from the first channel 213 enters the inner cavity of the separating screen 302. At the same time, the first motor 201 drives the separating screen 302 to rotate synchronously through the rotating drum 301, so that the sludge in the cavity of the separating screen 302 adheres to the inner wall of the separating screen 302 under the action of centrifugal force, and the water in the sludge enters the separating drum 216 through the through hole of the separating screen 302. The remaining sludge enters one end of the sludge discharge pipe 304 and is discharged outward under the scraping action of the second scraper 303.

[0049] This invention uses centrifugation to rapidly separate the discharged sludge from the water, thus accelerating the separation speed and efficiency. Furthermore, the separated sludge can be discharged externally, and the magnetic powder in the sludge can be recovered through further processing, reducing the cost of use.

[0050] For further explanation of the present invention, see Figures 1-7 ,

[0051] The first motor 201 is driven to the first gear ring 202 via a first gear 218 and a second gear 219. The output shaft of the first motor 201 is coaxially fixed with the first gear 218. The first gear 218 meshes with a plurality of second gears 219 in the circumferential direction. The second gears 219 are mounted on the separation barrel 216 via bearings. The second gears 219 mesh with the first gear ring 202.

[0052] Those skilled in the art can control the rotational speed of the first gear ring 202 by adjusting the transmission ratio between the first gear 218 and the second gear 219.

[0053] The first magnetic rod 203 is inclined, and its inclination direction is from top to bottom and from the center outwards.

[0054] The present invention ensures that the first magnetic rod 203 adheres closely to the side of the mud bucket 204 during rotation, thereby enhancing the adsorption effect.

[0055] The first spring 211 is always in a compressed state.

[0056] The present invention ensures that under the elastic force of the first spring 211, the other end of the first scraper 210 can always be in contact with the outer surface of the mud bucket 204.

[0057] The mud bucket 204 has a frustum-shaped outline.

[0058] The present invention ensures that the side of the sludge bucket 204 is inclined to facilitate the outward discharge of sludge.

[0059] The guide groove 215 has a wavy outline.

[0060] The present invention ensures that during the rotation of the guide rod 208 driven by the first guide hole 207, the guide rod 208 is smoothly driven to move up and down through the configuration relationship between the first pin 214 and the guide groove 215.

[0061] The first guide hole 207 has a square cross-sectional shape, and the guide rod 208 has a square cross-sectional shape that matches the cross-sectional shape of the first guide hole 207.

[0062] The present invention realizes the guiding function of the first guide hole 207 on the guide rod 208, ensuring that the guide rod 208 can only move up and down along the axial direction of the first guide hole 207.

[0063] For further explanation of the present invention, see Figure 4 , 8 ,

[0064] The sludge discharged from the sludge discharge pipe 304 is recycled as magnetic powder through the magnetic powder recovery mechanism 400. The magnetic powder recovery mechanism 400 includes a second motor 401, a second bevel gear 402, a third bevel gear 403, a spiral rod 404, a recovery box 405, a first pulley 406, a second pulley 407, a first transmission belt 408, a second magnetic rod 409, an adhesion plate 410, and a through hole 411.

[0065] The sedimentation tank 101 is fixedly connected to the second motor 401. The output shaft of the second motor 401 is coaxially fixed with the second bevel gear 402. The second bevel gear 402 meshes with the third bevel gear 403. The third bevel gear 403 is coaxially fixed with the screw rod 404. The screw rod 404 is disposed in the sludge discharge pipe 304 and rotates along it. The screw rod 404 is also mounted on the side wall of the recycling tank 405 by bearings.

[0066] The output shaft of the second motor 401 is coaxially fixed with the first pulley 406. The first pulley 406 is belt-driven to the second pulley 407 via the first transmission belt 408. The second pulley 407 is coaxially fixed with the second magnetic rod 409. Multiple adhesion plates 410 are uniformly fixed on the second magnetic rod 409 along its circumference. The second magnetic rod 409 and the adhesion plates 410 are disposed inside the recycling bin 405. The adhesion plates 410 and the second magnetic rod 409 can achieve the adsorption and adhesion of magnetic powder. The second magnetic rod 409 is mounted on the side wall of the recycling bin 405 by bearings. Multiple through holes 411 are uniformly opened at the bottom of the recycling bin 405.

[0067] The output shaft of the second motor 401 drives the screw rod 404 to rotate, discharging the sludge in the sludge discharge pipe 304 to the recycling box 405. At the same time, the output shaft of the second motor 401 drives the second magnetic rod 409 and the adhesion plate 410 to rotate in the recycling box 405 via belt drive. The rotation of the second magnetic rod 409 and the adhesion plate 410 adheres to and adsorbs the magnetic powder contained in the sludge discharged from the sludge discharge pipe 304, collecting the magnetic powder on the outer surface of the second magnetic rod 409 and the adhesion plate 410. The remaining sludge is discharged outward through the through hole 411 at the bottom of the recycling box 405.

[0068] Those skilled in the art can control the rotational speed of the screw rod 404 by adjusting the transmission ratio between the second bevel gear 402 and the third bevel gear 403.

[0069] The structure consisting of the second pulley 407, the second magnetic rod 409, and the adhesive plate 410 is symmetrically distributed in two groups about the center of the recycling bin 405.

[0070] For further explanation of the present invention, see Figure 4 , 9 ,

[0071] The second motor 401 also drives a stirring and adding mechanism 500, which includes a first stirring box 501, a second stirring box 502, a square rod 503, a first stirring shaft 504, a stirring blade 505, a second pin 506, a protrusion 507, a second spring 508, a third pulley 509, a second transmission belt 510, a fourth pulley 511, a second stirring shaft 512, a second channel 513, and a third channel 514.

[0072] The side of the sedimentation tank 101 is fixedly connected to the second mixing tank 502. The second mixing tank 502 is fixedly connected to the first mixing tank 501. The side of the first mixing tank 501 is fixedly connected to and communicates with the water inlet. The output shaft of the second motor 401 passes through the bottom of the first mixing tank 501 in a sealed manner and is coaxially fixed to one end of the square rod 503. The square rod 503 is arranged inside the first mixing shaft 504 and moves along it. A plurality of mixing blades 505 are evenly fixed on the outer circumferential surface of the first mixing shaft 504. The first mixing shaft 504 and the mixing blades 505 are arranged inside the first mixing tank 501. A plurality of second pins 506 are evenly fixed on the bottom of the first mixing shaft 504. The second pins 506 overlap with one end of the protrusion 507. The protrusion 507 is fixedly connected to the bottom of the first mixing tank 501.

[0073] The top of the first stirring shaft 504 is fixedly connected to one end of the second spring 508, and the other end of the second spring 508 is fixedly connected to the third pulley 509. The third pulley 509 is mounted on the top of the first stirring box 501 through bearings. The third pulley 509 is connected to the fourth pulley 511 through the second transmission belt 510. The second transmission belt 510 is mounted on the side wall of the second stirring box 502 through bearings. The fourth pulley 511 is coaxially fixed with the second stirring shaft 512. The second stirring shaft 512 is arranged inside the second stirring box 502.

[0074] The first mixing tank 501 is connected to the second mixing tank 502 through the second channel 513 opened at the bottom, and the second mixing tank 502 is connected to the sedimentation tank 101 through the third channel 514 opened at the top of the side wall of the sedimentation tank 101.

[0075] In this invention, the second motor 401 drives the first stirring shaft 504 to rotate within the first stirring tank 501, and adds magnetic powder and coagulant to the first stirring tank 501 to achieve rapid circulation stirring, thereby forming a "magnetic composite" with magnetic powder as the core. Furthermore, a coagulant is added to the second stirring tank 502 for further coagulation and polymerization, which facilitates adsorption during the subsequent sedimentation process, thereby accelerating the sedimentation efficiency.

[0076] The second motor 401 drives the square rod 503 to rotate, and through the configuration of the square rod 503 and the first stirring shaft 504, it drives the first stirring shaft 504 to rotate synchronously. During the rotation of the first stirring shaft 504, through the overlapping relationship between the second pin 506 and the protrusion 507, the first stirring shaft 504 rotates while moving up and down along the square rod 503. This combined motion ensures that the magnetic powder, mine water and coagulant in the first mixing tank 501 are fully mixed and stirred, which helps to form a coagulant. In addition, through the belt drive connection of the third pulley 509, the second transmission belt 510 and the fourth pulley 511, the second stirring shaft 512 drives the liquid in the second mixing tank 502 to further stir, so that the liquid in the second mixing tank 502 further condenses under the action of the coagulant and enters the sedimentation tank 101 through the third channel 514 to complete the sedimentation.

[0077] In this invention, the second spring 508 is always in a compressed state, ensuring that the second pin 506 is always in contact with the upper end face of the protrusion 507 under the elastic force of the second spring 508.

[0078] The upper surface of the protrusion 507 has a wavy shape. This invention ensures that during the rotation of the second pin 506, the first stirring shaft 504 is driven to move up and down by overlapping with the upper surface of the protrusion 507.

[0079] The square rod 503 has a square cross-sectional shape, and the inner surface of the first stirring shaft 504 has a square cross-sectional shape that matches the cross-sectional shape of the square rod 503. This invention enables the square rod 503 and the first stirring shaft 504 to rotate synchronously, and the first stirring shaft 504 to move up and down along the axial direction of the square rod 503.

[0080] The magnetic powder added to the first mixing tank 501 has a concentration of 2-10 mg / L, and coagulant PAC is added to the first mixing tank 501 at the same time, while coagulant PAM is added to the second mixing tank 502.

[0081] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
