Description

Technical Field

[0001] The invention relates to the technical field of underground sedimentation and filtration of mine water, and in particular to a mine water sedimentation and filtration system. Background Art

[0002] A large amount of mine water is produced during the coal mining process, and the mine water contains coal, rock, gravel and other debris.

[0003] During the coal mining process, different tunnels will be dug to provide passages for ventilation, transportation, pedestrians, etc. After the mining is completed, the tunnels will be idle and no longer used.

[0004] In the prior art, in order to improve the utilization rate of the tunnel, a reservoir or underground water reservoir is set in the tunnel to store mine water.

[0005] If the mine water is not filtered through sedimentation to remove coal, rock and gravel, more and more coal, rock and gravel and other debris will accumulate in the reservoir or underground reservoir, affecting the water capacity of the reservoir or underground reservoir.

[0006] Therefore, sedimentation tanks are usually arranged on waterways to settle debris such as coal, rock and gravel, or semi-high retaining walls are set up to block debris such as coal, rock and gravel.

[0007] However, when a certain amount of coal, rock, gravel and other debris accumulates in the sedimentation tank, or a certain amount of coal, rock, gravel and other debris is blocked by the retaining wall, dredging is required in a timely manner. In order to reduce the difficulty of dredging and ensure the safety of dredging operations, it is necessary to stop the operation of mine water-related equipment and interrupt the transportation of mine water during dredging. After dredging is completed, the mine water-related equipment will be turned on and the mine water will be transported again.

[0008] The defects of the existing technology are: sedimentation tanks, retaining walls, etc. need to be set up on the waterway of mine water, and dredging is required regularly. The dredging is difficult and time-consuming. The mine water transportation needs to be disconnected during dredging, which affects the sedimentation and purification efficiency of the mine water. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a mine water sedimentation and filtration system. A sedimentation and filtration device is arranged on the waterway of the tunnel, which can sediment impurities such as coal, rock and gravel in the water and can automatically throw the sediment into the tunnel, thereby eliminating the need to dredge the waterway. The entire process of sedimentation and throwing sediment will not disconnect the mine water transportation waterway, thereby greatly improving the sedimentation and purification efficiency of the mine water.

[0010] The technical solution of the present invention provides a mine water sedimentation and filtration system, comprising a water reservoir arranged in a tunnel, a water channel installed on a side of the tunnel, and a sedimentation and filtration device connected to the water channel and capable of automatically throwing sediments;

[0011] The sedimentation and filtration device comprises a mounting seat having a buffer water tank and a mounting groove, and a rotating body having two sedimentation tanks and two water storage chambers evenly distributed along the circumferential direction;

[0012] The mounting seat is connected between two adjacent sections of the water channel, the buffer water tank is located above the mounting tank, and a communication port is provided between the bottom of the buffer water tank and the top of the mounting tank;

[0013] The rotating body is pivotally mounted in the mounting groove, and the circumferential surface of the rotating body can block the communication port; along the rotation direction of the rotating body, a communication waterway is respectively provided between each of the sedimentation tanks and the downstream water storage chamber, and each of the water storage chambers is provided with a water outlet;

[0014] When one of the sedimentation tanks is docked with the connecting port to receive sediment, water will enter the water storage chamber on the downstream side of the sedimentation tank and can drive the rotating body to rotate through the eccentric weight. The water storage chamber containing water and the sedimentation tank containing sediment will rotate downward in sequence with the rotating body, and the water will be discharged and the sediment will be thrown down at the same time. The other sedimentation tank will rotate with the rotating body to a docking state with the connecting port.

[0015] In one of the optional technical solutions, a plurality of sets of the sedimentation and filtration devices are arranged at intervals on the waterway.

[0016] In one of the optional technical solutions, along the rotation direction of the rotating body, the edge of the communication port is divided into an upstream side edge and a downstream side edge;

[0017] The upstream side edge is provided with a downwardly bent elastic claw for inserting into the sedimentation tank docking with the communication port to temporarily limit the rotating body.

[0018] In one of the optional technical solutions, the water outlet is arranged at one end of the notch of the sedimentation tank close to the upstream side of the water storage chamber.

[0019] In one of the optional technical solutions, a water baffle is hinged in the water outlet;

[0020] In the rotation direction of the rotating body, the downstream end of the water baffle is hinged to the downstream side edge of the water outlet.

[0021] In one of the optional technical solutions, the surface of the mounting groove is an arc surface, and the curvature radius of the arc surface is greater than the curvature radius of the rotating body;

[0022] When the sedimentation tank and the communication port are in a docking state, the surface of the rotating body and the surfaces of the installation slot on both sides of the communication port are kept in contact.

[0023] In one of the optional technical solutions, a filter is provided in the connecting water channel.

[0024] In one of the optional technical solutions, a plurality of connecting waterways are provided between the sedimentation tank and the downstream water storage chamber.

[0025] In one of the optional technical solutions, a storage tank is provided in the tunnel below the sedimentation and filtering device, for storing water discharged and sediment thrown down by the sedimentation and filtering device.

[0026] In one of the optional technical solutions, a square shaft is provided at one end of the rotating body for cooperating with a tool to rotate the rotating body.

[0048] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. The same components are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0049] like Figure 1-9 , Figure 11-12 and Figure 15-18As shown, a mine water sedimentation and filtration system provided by one embodiment of the present invention includes a water reservoir 1 arranged in a tunnel 100, a water channel 2 installed on a side wall 101 of the tunnel 100, and a sedimentation and filtration device 3 connected to the water channel 2 and capable of automatically throwing down sediment 8.

[0050] The sedimentation and filtration device 3 comprises a mounting seat 31 having a buffer water tank 313 and a mounting tank 314 and a rotating body 32 having two sedimentation tanks 323 and two water storage chambers 324 evenly distributed along the circumferential direction.

[0051] The mounting seat 31 is connected between two adjacent sections of the water channel 2 . The buffer water tank 313 is located above the mounting tank 314 . A communication port 315 is provided between the bottom of the buffer water tank 313 and the top of the mounting tank 314 .

[0052] The rotating body 32 is pivotally mounted in the mounting groove 314, and the circumferential surface of the rotating body 32 can block the communication port 315. In the rotation direction of the rotating body 32, a communication waterway 325 is respectively provided between each sedimentation tank 323 and the downstream water storage chamber 324, and each water storage chamber 324 is provided with a water outlet 3241.

[0053] When one of the sedimentation troughs 323 is docked with the connecting port 315 to receive the sediment 8, water will enter the water storage chamber 324 on the downstream side of the sedimentation trough 323 and can drive the rotating body 32 to rotate through the eccentric weight. The water storage chamber 324 containing water and the sedimentation trough 323 containing the sediment 8 will rotate downward in sequence with the rotating body 32, and at the same time, the water will be discharged and the sediment 8 will be thrown down. The other sedimentation trough 323 will rotate with the rotating body 32 to a docking state with the connecting port 315.

[0054] The present invention provides a mine water sedimentation and filtration system, which is used to be arranged in the tunnel 100, to sediment and filter the mine water, and then output the sedimentation and filtered mine water, which can be used for underground production and dust removal. The mine water can also be filtered and purified to remove suspended matter, etc., and then output to the surface for use.

[0055] The mine water sedimentation and filtration system includes a water reservoir 1, a waterway 2, a sedimentation and filtration device 3, etc.

[0056] The water reservoir 1 is constructed in the lane 100 , and the lane walls 101 on both sides are used as the pool walls of the water reservoir 1 . The water reservoir 1 can be formed by selecting a suitable length to construct a retaining wall along the extension direction of the lane 100 .

[0057] The water channel 2 is arranged in the tunnel 100 and is used to transport mine water to the water reservoir 1. The water channel 2 is formed by connecting a plurality of U-shaped plates in sequence. One side of the water channel 2 is installed on a side tunnel wall 101, and the other side is supported by a bracket. The width of the water channel 2 is smaller than the width of the tunnel 100. A water supply pipe 4 is connected to the head end of the water channel 2, and the water supply pipe 4 is connected to the water supply pump at the front end to transport mine water to the water channel 2. The tail end of the water channel 2 extends into the water reservoir 1 to transport the mine water to the water reservoir 1.

[0058] The water reservoir 1 is connected to a pumping pipe 5, which is laid on the floor of the tunnel 100 and is used to output the mine water in the water reservoir 1 to a designated place. A pumping pump can be arranged in the pumping pipe 5 or the water reservoir 1 as needed.

[0059] Preferably, in the direction from the head end to the tail end of the water channel 2, the water channel 2 gradually extends downwardly, which is beneficial to the transportation of mine water.

[0060] Preferably, the width of the water channel 2 is between 1 / 2 and 2 / 3 of the width of the lane 100. Preferably, mounting plates 21 are provided on both side walls of each section of the water channel 2 for connection with the lane wall 101 and the bracket.

[0061] The sedimentation and filtration device 3 is installed between two sections of the waterway 2. The sedimentation and filtration device 3 is arranged roughly perpendicular to the direction of the waterway 2. It is used to sediment and filter the mine water and automatically throw the settled sediment 8 into the tunnel 100, thereby saving the dredging step.

[0062] Specifically, the sedimentation filtering device 3 includes a mounting seat 31 and a rotating body 32 , and both the mounting seat 31 and the rotating body 32 are metal parts.

[0063] The mounting seat 31 includes a buffer water tank 313 at the top and a mounting groove 314 at the bottom, which are connected via a connecting port 315. The buffer water tank 313 is generally funnel-shaped, and the buffer water tank 313 gradually contracts or its width gradually narrows in the direction from top to bottom. The mounting groove 314 is expansion-shaped, and the buffer water tank 313 gradually expands or its width gradually widens in the direction from top to bottom. The width direction referred to here refers to the direction along the direction of the waterway 2.

[0064] The mounting seat 31 is connected between two sections of the water channel 2, and the mine water in the water channel 2 will enter the buffer tank 313 for buffering, thereby settling debris such as coal, rock and gravel.

[0065] The rotating body 32 is generally cylindrical, and has rotating shafts 321 at both ends thereof, so as to be assembled into the mounting holes 316 of the groove walls at both ends of the mounting groove 314. The rotating body 32 can rotate in the mounting groove 314, and the circumferential surface of the rotating body 32 can block the communication port 315 to prevent the mine water from leaking down. If necessary, a rubber sealing sheet can be provided at the edge of the communication port 315 to achieve sealing with the circumferential surface of the rotating body 32.

[0066] The rotating body 32 is provided with two sedimentation tanks 323 and two water storage chambers 324. Specifically, the two sedimentation tanks 323 are arranged symmetrically about the axis of the rotating body 32, and the two water storage chambers 324 are also arranged symmetrically about the axis of the rotating body 32. The central angle between adjacent sedimentation tanks 323 and water storage chambers 324 is approximately 90°, that is, the center line of a pair of water storage chambers 324 intersects and is perpendicular to the center line of a pair of sedimentation tanks 323.

[0067] The notch of the sedimentation trough 323 is at the edge of the rotating body 32. When one of the notches is facing upward, the other notch is facing downward. When the notch of the sedimentation trough 323 is facing upward, it can dock with the upper connecting port 315, and debris such as coal, rock, and gravel and water will enter the sedimentation trough 323 docked with the connecting port 315. After the rotating body 32 rotates a certain angle, the debris such as coal, rock, and gravel in the sedimentation trough 323 will be automatically thrown into the roadway 100. During the rotation of the rotating body 32, the surface of the rotating body 32 always keeps in contact with the bottom surface on both sides of the connecting port 315. In this process, water leakage occurs in time, and the amount of water leakage is relatively small and within the acceptable range.

[0068] The width of the notch of the sedimentation tank 323 may be smaller than the width of the communication opening 315 , or may be slightly larger than the width of the communication opening 315 .

[0069] For the convenience of description, the positions of the sedimentation tank 323, the water storage chamber 324, etc. are distinguished and defined according to the rotation direction of the rotating body 32. For example, if the direction from a sedimentation tank 323 to a water storage chamber 324 is along the rotation direction of the rotating body 32, then the water storage chamber 324 is located on the downstream side of the sedimentation tank 323. The upstream-downstream side edges and upstream-downstream ends involved below are defined and divided in a similar manner.

[0070] A connecting waterway 325 is connected between each sedimentation tank 323 and a water storage chamber 324 on the downstream side of the sedimentation tank. The connecting waterway 325 is a passage. The water entering the sedimentation tank 323 through the connecting port 315 will gradually gather into the water storage chamber 324 on the downstream side through the connecting waterway 325 to increase the weight in the water storage chamber 324 on the downstream side, thereby utilizing the eccentric gravity on the downstream side to drive the rotating body 32 to rotate automatically. The setting of the eccentric gravity can be designed in advance according to the friction between the rotating body 32 and the surface of the mounting groove 314, so as to design a water storage chamber 324 of a suitable size. A water outlet 3241 is provided at the edge of each water storage chamber 324. When the rotating body 32 rotates a certain angle, the water in the water storage chamber 324 begins to be discharged.

[0071] As soon as the rotating body 32 starts to rotate, the sedimentation tank 323 containing the sediment 8 also deflects accordingly, and the eccentric gravity of the sediment 8 will cause the rotating body 32 to rotate quickly. When the notch of the sedimentation tank 323 is tilted downward, the sediment 8 will be automatically thrown out. When the rotating body 32 rotates about 180°, the notch of the sedimentation tank 323 is vertically downward, and the sediment 8 will be completely thrown out. In this process, a large amount of water in the water storage chamber 324 will also be discharged and drained. When the rotating body 32 rotates about 180°, the rotating body 32 is basically no longer affected by the eccentric gravity in the horizontal direction, and the friction force makes the rotating body 32 stop. At this time, the notch of the other sedimentation tank 323 faces upward and docks with the connecting port 315 to receive the sediment 8, and the next cycle of receiving the sediment 8 and rotating and throwing the sediment 8 is carried out.

[0072] In the present invention, the rotation of the rotating body 32 mainly depends on the gravity of the water in a water storage chamber 324 offset on the downstream side and the gravity of the sediment 8 in the deflected sedimentation tank 323, without the need for an additional power mechanism, thus saving costs.

[0073] Figure 16-18 The process of the rotating body 32 rotating 180° is shown in the figure. The mine water flows in the waterway 2 approximately along the direction of arrow a, the water in the water storage chamber 324 is discharged approximately along the direction of arrow b, and the sediment 8 in the sedimentation tank 323 is thrown down approximately along the direction of arrow c.

[0074] The mine water sedimentation and filtration system provided by the present invention comprises a water reservoir 1, a waterway 2 and a sedimentation and filtration device 3. The waterway 2 is arranged on a side of a tunnel 101 of a tunnel 100, and the water reservoir 1 is arranged in the depth of the tunnel 100. The sedimentation and filtration device 3 is arranged on the waterway 2, and is used to sediment coal, rock, gravel and other debris (sediment 8), and can automatically throw the sediment 8 after sedimentation into the tunnel 100, without dredging the waterway 2, and the entire sedimentation and throwing sediment 8 process will not disconnect the mine water transportation waterway, which greatly improves the sedimentation and purification efficiency of the mine water.

[0075] In one embodiment, if Figure 8-9 As shown, the mounting seat 31 is generally box-shaped, and includes a base portion 311 and a cover portion 312 connected to the base portion 311, a mounting groove 314 is provided on the base portion 311, and a buffer water tank 313 is provided on the cover portion 312. Mounting holes 316 are respectively provided on two sections of the groove wall along the length direction of the mounting groove 314 for assembling the rotating shaft 321 of the rotating body 32.

[0076] In one embodiment, if Figure 2-3 , Figure 4-9 and Fig.15 As shown, the cover part 312 is connected to the water channel 2 through the rubber sealing block 7. The front and rear of the cover part 312 are respectively provided with docking grooves 317, and the front and rear ends of the side wall and the bottom plate of the water channel 2 are respectively provided with embedded grooves 22. One end of the rubber sealing block 7 is embedded in the embedded groove 22, and the other end thereof is embedded in the docking groove 317, so that the mounting seat 31 and the water channel 2 are flexibly connected and can be sealed.

[0077] In one embodiment, if Figure 2 and Figure 4 As shown, the top surface of the mounting seat 31 is an inclined surface, and its inclination is roughly consistent with the inclination of the bottom plate of the waterway 2, which is conducive to the flow of water.

[0078] In one embodiment, if Figure 7 and Fig. 9 As shown, the upstream side slope 313a and the downstream side slope 313b of the buffer water tank 313 are both arc-shaped surfaces, wherein the curvature radius of the upstream side slope 313a is greater than the curvature radius of the downstream side slope 313b. In other words, the downstream side slope 313b is steeper than the upstream side slope 313a, which increases the difficulty for debris such as coal, rock and gravel to leave the buffer water tank 313 through the downstream side slope 313b. After the mine water containing debris such as coal, rock and gravel is guided into the buffer water tank 313 through the upstream side slope 313a, most of it will remain in the buffer water tank 313, and then fall through the connecting port 315.

[0079] In one embodiment, if Figure 5-6 and Fig.11 As shown, the rotating body 32 includes a relatively thick main body 320, and the buffer water tank 313 and the mounting groove 314 are arranged on the main body 320. The retaining rings 322 are arranged at both ends of the main body 320, and the rotating shaft 321 is connected to the outer side of the retaining ring 322. During assembly, the retaining ring 322 contacts the wall surface of the mounting groove 314, which can avoid abrasion of the main body 320.

[0080] In one embodiment, if Figure 1-2 As shown, a plurality of sedimentation and filtration devices 3 are arranged at intervals on the waterway 2 to improve the sedimentation and filtration effect.

[0081] In one embodiment, if Figure 7 and Figure 9-10 As shown, along the rotation direction of the rotating body 32, the edge of the communication port 315 is divided into an upstream side edge 315a and a downstream side edge 315b.

[0082] The upstream side edge 315 a is provided with a downwardly bent elastic claw 315 c for being inserted into a sedimentation tank 323 connected to the communication port 315 to temporarily limit the rotating body 32 .

[0083] The elastic claw 315c is a metal spring sheet, which is slightly tilted and bent downward. Whenever the notch of a sedimentation tank 323 rotates upward and docks with the connecting port 315, the elastic claw 315c is inserted into the sedimentation tank 323 to fit tightly against the top of the upstream wall of the sedimentation tank 323, thereby preventing the rotating body 32 from continuing to rotate. When the gravity of the water in the water storage chamber 324 on the downstream side is sufficient to overcome the sum of the friction between the rotating body 32 and the wall of the installation groove 314 and the friction between the elastic claw 315c and the wall of the sedimentation tank 323, the rotating body 32 starts to rotate.

[0084] In one embodiment, if Figure 1-2 As shown, Fig.12 As shown, the water outlet 3241 is disposed at one end of the notch of the water storage chamber 324 near the upstream side of the settling tank 323. At the beginning of the rotation of the rotating body 32, the water outlet 3241 of the downstream side of the water storage chamber 324 is generally upward, and water does not flow out, and the eccentric gravity is maintained on the rotating body 32.

[0085] In one embodiment, if Figure 13-14 As shown, a water baffle plate 327 is hinged in the water outlet 3241. In the rotation direction of the rotating body 32, the downstream end 327b of the water baffle plate 327 is hinged to the downstream side edge 3241b of the water outlet 3241.

[0086] If water is poured into the water storage chamber 324 through the water outlet 3241, the water storage chamber 324 will be quickly filled with water, shortening the residence time of the rotating body 32, thereby reducing the time for the receiving sedimentation tank 323 to receive the sediment 8, and reducing the amount of sediment 8 received by the sedimentation tank 323 each time.

[0087] In this embodiment, by disposing a water baffle 327 at the water outlet 3241 , it is possible to prevent water from flowing into the water storage chamber 324 through the water outlet 3241 when the water outlet 3241 passes through the connecting port 315 .

[0088] Specifically, the two ends of the water baffle 327 are divided into an upstream end 327a and a downstream end 327b, and the edge of the water outlet 3241 is divided into an upstream side edge 3241a and a downstream side edge 3241b. The downstream end 327b of the water baffle 327 is hinged to the downstream side edge 3241b of the water outlet 3241 through a pivot shaft. The upstream end 327a of the water baffle 327 can cover the upstream side edge 3241a of the water outlet 3241.

[0089] When the water baffle plate 327 is above the horizontal center line of the rotating body 32 , the water baffle plate 327 is in an inclined state, and under the action of gravity, the water baffle plate 327 automatically covers the water outlet 3241 .

[0090] When the water baffle plate 327 is below the horizontal center line of the rotating body 32 , the water baffle plate 327 automatically opens the water outlet 3241 under the action of gravity.

[0091] like Fig.13 As shown, assuming that the rotating body 32 rotates clockwise, Fig.13 When the water baffle 327 on the right side roughly passes the horizontal center line of the rotating body 32, it will automatically open and the water storage chamber 324 will start to drain. The rotating body 32 continues to rotate, and when the pivot axis of the water baffle 327 on the right side passes the vertical center line of the rotating body 32, it opens to the maximum angle. Afterwards, as the rotating body 32 rotates, the water baffle 327 gradually closes and is also closed by the wall of the installation groove 314.

[0092] As needed, a configuration may be provided at the upstream end 327a of the water baffle 327 to increase weight, or the center of gravity of the water baffle 327 may be set close to the upstream end 327a, which is conducive to automatically opening and closing the water baffle 327 by gravity.

[0093] In one embodiment, if Figure 7 and Fig. 9 As shown, the surface of the mounting groove 314 is an arc surface, and the curvature radius of the arc surface is greater than the curvature radius of the rotating body 32 .

[0094] When the sedimentation tank 323 and the communication port 315 are in a docking state, the surface of the rotating body 32 and the surfaces of the installation groove 314 on both sides of the communication port 315 are kept in contact with each other.

[0095] In this embodiment, the cross-section of the mounting groove 314 along the width direction is arc-shaped, and its curvature radius is greater than the curvature radius of the rotating body 32, so that the top surface of the rotating body 32 can fit with the top surface of the mounting groove 314 to achieve sealing and water blocking, while leaving rotation space for the rotating body 32 in the lower half.

[0096] In one embodiment, if Figure 7 and Fig.12As shown, a filter screen 326 is provided in the communicating waterway 325 to prevent stones and the like from entering the water storage chamber 324. The filter screen 326 is preferably provided at the water inlet of the communicating waterway 325, that is, on the wall surface on the downstream side of the sedimentation tank 323, and the blocked stones and the like directly fall into the sedimentation tank 323 and will be thrown down with the rest of the sediment.

[0097] In one embodiment, if Figure 6 and Fig.11 As shown, a plurality of communicating waterways 325 are provided between the sedimentation tank 323 and the downstream water storage chamber 324. When one or several communicating waterways 325 are blocked, the remaining communicating waterways 325 continue to function.

[0098] In one embodiment, if Figure 2 and Figure 15-18 As shown, a storage tank 103 is provided below the corresponding sedimentation filtering device 3 in the lane 100, which is used to store the water discharged by the sedimentation filtering device 3 and the discarded sediment 8, so as to prevent the discarded sediment and the drained water from being randomly stacked and flowing in the lane 100, thereby keeping the working environment in the lane 100 undisturbed.

[0099] In one embodiment, if Figure 5-6 and Fig.11 As shown, a square shaft 3211 is provided at one end of the rotating body 32 for cooperating with a tool to rotate the rotating body 32.
