Description

Technical Field

[0001] This invention relates to the field of water tank sludge discharge technology, and in particular to a water tank sludge discharge device for mining operations. Background Technology

[0002] During underground mining, groundwater can seep into the mine shafts, creating stagnant water. Underground water tanks collect and drain this water, preventing flooding and ensuring normal mine operations and personnel safety. Due to the unique underground environment, the groundwater collected in these tanks often contains a large amount of silt, necessitating sludge removal to prevent disruption to their operation. Currently, silt removal from underground water tanks typically involves pumps and sludge removal pipes. However, this process requires first draining the surface water from the tanks, making it cumbersome.

[0003] To address this, we propose a sludge removal device for mining water storage that can filter and separate silt mixed in with water for direct pumping. Summary of the Invention

[0004] In order to overcome the shortcomings of existing sludge discharge structures that require the surface water in the water tank to be discharged before sludge can be pumped out, this invention provides a sludge discharge device for mining water tanks that can filter and separate sludge mixed in with water for direct pumping.

[0005] A sludge removal device for mining water tanks includes a water tank, an inlet pipe connected to the top of the water tank, a sand-draining pipe connected to the water tank, a suction pump fixedly connected to the side of the top of the water tank away from the inlet pipe, the suction pump being connected to the sand-draining pipe, an extraction frame connected to the bottom of the sand-draining pipe, and an electric push rod fixedly connected to the water tank. The telescopic end of the electric push rod passes through the water tank and connects to the extraction frame. A conveying group is rotatably connected inside the water tank. The conveying group is fixedly connected to equidistantly distributed mesh frames. The mesh frames are slidably connected to symmetrically arranged sliding rods. Mesh plates are connected between the symmetrically arranged sliding rods. A first spring is connected between the sliding rods and the adjacent mesh frames.

[0006] In one embodiment, a water control mechanism for squeezing water out of the mesh frame is also included. The water control mechanism is disposed in the water tank and includes symmetrically arranged contact plates fixedly connected to the water tank. The mesh frame is fixedly connected to symmetrically arranged fixing rods. The fixing rods are slidably connected to extrusion blocks. The extrusion blocks are in pressure engagement with the contact plates. A second spring is connected between the extrusion blocks and adjacent fixing rods. The mesh frame is fixedly connected to symmetrically arranged limiting plates. The limiting plates contact adjacent extrusion blocks and limit the extrusion blocks.

[0007] In one embodiment, a locking mechanism for maintaining the squeezing state is also included. The locking mechanism is disposed in the extraction frame and includes symmetrically arranged pressing blocks. The symmetrically arranged pressing blocks are fixedly connected to the extraction frame. A locking block is slidably connected to the side of the limiting plate away from the squeezing block. A contact block is fixedly connected to the locking block. The contact block is pressed and engaged with the adjacent pressing block. A third spring is connected between the locking block and the adjacent limiting plate.

[0008] In one embodiment, the side of the card block away from the frame is inclined, and the card block is pressed and engaged with the adjacent extrusion block.

[0009] In one embodiment, a striking mechanism for striking the mesh plate is also included. The striking mechanism is disposed in the water tank and includes equidistantly distributed extrusion plates. The equidistantly distributed extrusion plates are fixedly connected to the water tank. The mesh plate is rotatably connected to a rotating rod. The rotating rod is fixedly connected to equidistantly distributed striking blocks. A first gear is fixedly connected to the side of the rotating rod near the extrusion plate. A torsion spring is connected between the first gear and the adjacent mesh plate. A guide block is fixedly connected to the side of the mesh plate near the first gear. A first rack is slidably connected to the guide block. The first rack meshes with the adjacent first gear. A contact rod is fixedly connected to the first rack.

[0010] In one embodiment, the striking block is a telescopic structure.

[0011] In one embodiment, the contact rod is L-shaped and the extrusion plate is triangular, with the contact rod and the extrusion plate forming a pressing fit.

[0012] In one embodiment, a sludge suction mechanism is also included for suctioning the sediment settled at the bottom of the water tank. The sludge suction mechanism is set in the mesh frame and includes symmetrically arranged spring telescopic rods. The symmetrically arranged spring telescopic rods are fixedly connected to the mesh frame. Symmetrically arranged guide rods are fixedly connected inside the water tank. A suction frame is slidably connected between the symmetrically arranged guide rods. A fourth spring is connected between the suction frame and the guide rods. Symmetrically arranged vertical rods are fixedly connected to the suction frame. The vertical rods are pressed and engaged with adjacent spring telescopic rods. A symmetrically connected pipe is connected between the suction frame and the sand suction pipe.

[0013] In one embodiment, the connecting tube is a flexible tube to allow the suction frame to move.

[0014] In one embodiment, a pushing mechanism for pushing silt to be extracted by the suction frame is also included. The pushing mechanism is disposed in the water tank and includes a second rack that is equidistantly distributed. The second rack is fixedly connected to the water tank. The suction frame is rotatably connected to a screw rod. The screw rod is threadedly connected to a push plate. The push plate is slidably connected to the suction frame. A second gear is fixedly connected to the side of the screw rod near the second rack. The second gear meshes with the second rack.

[0015] The present invention has the following advantages: 1. The water discharged downward into the water tank through the inlet pipe will flow between the mesh frame and the mesh plate. The mesh plate and the mesh frame work together to filter and separate the mud and sand in the water. The suction pump operates to draw the mud and sand upward through the sand suction pipe and the extraction frame. The rotating mesh frame and the mesh plate continuously filter and separate the mud and sand mixed in the water. Then it is transported to the bottom of the extraction frame and directly sucked out of the water tank. In this way, it is more convenient to discharge mud from the water tank without emptying the surface water.

[0016] 2. The squeezing of the extrusion block and the contact plate can cause the mesh frame and mesh plate to move closer together, thereby squeezing the mud and sand in the mesh frame to control water and reduce the water content in the mud and sand.

[0017] 3. The clamping block holds the squeezing block, keeping the mesh frame and mesh plate in a squeezed state as they move. When the mesh frame and mesh plate move to the bottom of the extraction frame, the pressing block and the contact block squeeze together, causing the clamping block to release the squeezing block. The mesh plate and mesh frame open so that the extraction frame can suck up the mud and sand. In this way, the mesh frame and mesh plate can be kept in a squeezed state as they move to the bottom of the extraction frame, preventing the mud and sand from getting wet again during the movement.

[0018] 4. The striking block continuously rotates in both directions to strike the mesh plate, causing the mesh plate to vibrate and increasing the speed at which water is released from the mud and sand.

[0019] 5. The suction frame moves intermittently left and right to suction the sediment deposited at the bottom of the water tank, reducing sediment accumulation at the bottom of the water tank and improving the sludge removal effect.

[0020] 6. The push plate slides back and forth, pushing the mud and sand at the bottom of the water tank, causing the mud and sand to surge up so that the suction frame can extract the mud and sand. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0037] Example 1: A sludge removal device for a water storage tank in mining operations, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a water tank 1, an inlet pipe 2, a sand-dredging pipe 3, a suction pump 301, an extraction frame 4, an electric push rod 41, a conveying group 5, a mesh frame 6, a sliding rod 7, a mesh plate 8, and a first spring 9. The inlet pipe 2 is connected to the upper right side of the water tank 1, and the sand-dredging pipe 3 is connected to the upper left side of the water tank 1. The suction pump 301 is fixedly connected to the upper left side of the water tank 1, and the suction pump 301 is connected to the upper end of the sand-dredging pipe 3. The extraction frame 4 is connected to the lower end of the sand-dredging pipe 3. The electric push rod 41 is fixedly connected to the upper left side of the water tank 1. The telescopic end of the electric push rod 41 passes through the water tank 1 and connects to the extraction frame 4. The conveying group 5 is rotatably connected inside the water tank 1. The mesh frames 6 are fixedly connected at equal intervals. The mesh frames 6 are slidably connected to the front and rear symmetrical sliding rods 7. The mesh plates 8 are connected between the front and rear symmetrical sliding rods 7. The first spring 9 is connected between the sliding rods 7 and the adjacent mesh frames 6.

[0038] When using this device, the water in the well is introduced into the water tank 1 through the inlet pipe 2. The downward-flowing water flows between the mesh frame 6 and the mesh plate 8. At this time, the mesh plate 8 and the mesh frame 6 work together to filter and separate the mud and sand in the water. The conveying group 5 can drive the mesh frame 6 and the mesh plate 8 containing the mud and sand to move to the left. The mesh frame 6 and the mesh plate 8 behind then filter the water that is subsequently discharged. When the mesh frame 6 and the mesh plate 8 containing the mud and sand move to below the extraction frame 4, the electric push rod 4... The extension of the extraction frame 4 causes it to connect downwards to the mesh frame 6 and the mesh plate 8. The operation of the suction pump 301 allows the mud and sand to be drawn upwards through the sand suction pipe 3 and the extraction frame 4. After the suction is completed, the electric push rod 41 shortens, causing the extraction frame 4 to move upwards and reset. The rotating mesh frame 6 and mesh plate 8 continuously filter and separate the mud and sand mixed in the water, and then transport it to the bottom of the extraction frame 4 for direct suction and discharge outside the water tank 1. In this way, it is more convenient to discharge mud from the water tank 1 without emptying the surface water.

[0039] Example 2: Based on Example 1, such as Figure 5 and Figure 6 As shown, it also includes a water control mechanism, which can squeeze out the water in the mesh frame 6. The water control mechanism includes a contact plate 10, a fixed rod 11, a squeezing block 12, a second spring 13, and a limiting plate 14. The contact plate 10 is fixedly connected to both the front and rear sides of the upper right position in the water tank 1. The fixed rod 11 is fixedly connected to both the front and rear sides of the mesh plate 8. The squeezing block 12 is slidably connected to the fixed rod 11. The squeezing block 12 is squeezed and engaged with the contact plate 10. The second spring 13 is connected between the squeezing block 12 and the adjacent fixed rod 11. The limiting plate 14 is fixedly connected to both the front and rear sides of the mesh frame 6. The limiting plate 14 contacts the adjacent squeezing block 12 and limits the squeezing block 12.

[0040] Water may remain in the silt filtered and separated within the mesh frame 6 and mesh plate 8. A water control mechanism can be used to compress the silt and reduce its water content. The specific operation is as follows: When the mesh plate 8 and mesh frame 6 move to the left, it also drives the fixing rod 11 and the pressing block 12 to move to the left. When the pressing block 12 moves to the left and contacts the contact plate 10, the limiting plate 14 limits the pressing block 12, preventing the symmetrically positioned pressing blocks 12 from sliding inwards. At this point, the contact plate 10 blocks the pressing block 12, thereby fixing the position of the mesh plate 8 via the fixing rod 11. As the conveying group 5 continues to move the mesh frame 6 to the left, the mesh frame 6 slides on the sliding rod 7, causing the first spring 9 to deform. The mesh frame 6 then slides towards the sliding rod 7. The mesh plate 8 works in conjunction with the squeezing of mud and sand to control water. As the mesh frame 6 continues to move to the left, it also drives the limiting plate 14 to move to the left. When the limiting plate 14 moves to the left and is misaligned with the squeezing block 12, the limiting plate 14 no longer limits the squeezing block 12. At this time, the squeezing block 12 can be squeezed inward by the contact plate 10. The second spring 13 deforms, and after the squeezing block 12 slides inward, it disengages from the contact plate 10. Then, under the reset action of the second spring 13, the squeezing block 12 slides outward to reset. Under the reset action of the first spring 9, the slide rod 7 drives the mesh plate 8 to move to the left to reset. In this way, the mud and sand in the mesh frame 6 can be squeezed to control water and reduce the water content in the mud and sand.

[0041] like Figure 7 and Figure 8 As shown, it also includes a locking mechanism that can maintain the water-squeezing state. The locking mechanism includes a pressing block 15, a locking block 16, a contact block 161, and a third spring 17. The pressing blocks 15 are fixedly connected to both the front and rear sides of the extraction frame 4. The locking block 16 is slidably connected to the side of the limiting plate 14 away from the squeezing block 12. The side of the locking block 16 away from the mesh frame 6 is inclined. The locking block 16 is squeezed and engaged with the adjacent squeezing block 12. The contact block 161 is fixedly connected to the locking block 16. The contact block 161 is squeezed and engaged with the adjacent pressing block 15. The third spring 17 is connected between the locking block 16 and the adjacent limiting plate 14.

[0042] By setting a locking mechanism, the mesh frame 6 and mesh plate 8 can be kept in a compressed state as they move below the extraction frame 4, preventing the discharged water from splashing back into the mud and sand after squeezing. The specific operation is as follows: When the limiting plate 14 moves to the left with the mesh frame 6, the locking block 16 also moves to the left. When the limiting plate 14 moves to the left and is misaligned with the squeezing block 12, the squeezing block 12 slides inward, squeezing the locking block 16 to slide to the left and retract into the limiting plate 14. The third spring 17 deforms. When the squeezing block 12 slides inward and disengages from the locking block 16, under the action of the third spring 17 resetting, the locking block 16 slides to the right and extends to lock the squeezing block 12, thereby fixing the squeezing block 12. The position keeps the mesh frame 6 and mesh plate 8 in a compressed state. When the mesh frame 6 and mesh plate 8 move to below the extraction frame 4, the extraction frame 4 moves downward, causing the pressing block 15 to move downward. When the pressing block 15 moves downward and contacts the contact block 161, the pressing block 15 continues to move downward, which will press the contact block 161 to move to the left. The contact block 161 moves to the left, causing the sliding block 16 to retract into the limiting plate 14, thereby releasing the pressing block 12. At this time, the mesh plate 8 and mesh frame 6 open and reset, so that the extraction frame 4 can suck up the mud and sand. In this way, the mesh frame 6 and mesh plate 8 can be kept in a compressed state when moving to below the extraction frame 4, avoiding the mud and sand from soaking in water again during the movement.

[0043] like Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown, it also includes a striking mechanism that can strike the mesh plate 8. The striking mechanism includes a pressing plate 18, a rotating rod 19, striking blocks 20, a first gear 21, a torsion spring 211, a guide block 22, a first rack 23, and a contact rod 24. The pressing plate 18 is fixedly connected to the middle of the front side of the water tank 1 at equal intervals. The rotating rod 19 is rotatably connected to the mesh plate 8. Three striking blocks 20 are fixedly connected to the rotating rod 19 at equal intervals. The striking blocks 20 are extendable. The structure is compressed. A first gear 21 is fixedly connected to the front of the rotating rod 19. A torsion spring 211 is connected between the first gear 21 and the adjacent mesh plate 8. A guide block 22 is fixedly connected to the front of the mesh plate 8. A first rack 23 is slidably connected inside the guide block 22. The first rack 23 meshes with the adjacent first gear 21. A contact rod 24 is fixedly connected to the first rack 23. The contact rod 24 is L-shaped. The extrusion plate 18 is triangular. The contact rod 24 and the extrusion plate 18 are in a pressing fit.

[0044] By setting up a striking mechanism, the mesh plate 8 can be struck to further drain the water in the mud and sand. The specific operation is as follows: The mesh plate 8 moves to the left, causing the rotating rod 19, striking block 20, first gear 21, guide block 22, first rack 23, and contact rod 24 to move to the left. When the contact rod 24 moves to the left and contacts the extrusion plate 18, the contact rod 24 continues to move to the left and is squeezed upward by the extrusion plate 18. The upward movement of the contact rod 24 causes the first rack 23 to slide upward. The upward sliding of the first rack 23 causes the first gear 21 to rotate, and the torsion spring 211 deforms. The rotation of 21 drives the rotating rod 19 to rotate, which in turn drives the striking block 20 to rotate. The striking block 20 strikes the mesh plate 8. When the contact rod 24 moves to the left and disengages from the extrusion plate 18, the first gear 21 drives the rotating rod 19 to reverse and reset under the action of the torsion spring 211. At the same time, it drives the first rack 23 and the contact rod 24 to move downward and reset. When the contact rod 24 moves to the left and contacts the next extrusion plate 18, the above actions are repeated so that the striking block 20 can continuously rotate in both directions to strike the mesh plate 8, thereby increasing the speed of water separation from the mud and sand.

[0045] like Figure 1 , Figure 2 and Figure 12 As shown, it also includes a sludge suction mechanism, which can suction the sediment settled at the bottom of the water tank 1. The sludge suction mechanism includes a spring telescopic rod 25, a guide rod 26, a suction frame 27, a fourth spring 271, a vertical rod 28, and a connecting pipe 29. The leftmost and rightmost mesh frames 6 are each fixedly connected with symmetrical spring telescopic rods 25. The lower part of the water tank 1 is fixedly connected with symmetrical guide rods 26. The suction frame 27 is slidably connected between the symmetrical guide rods 26. The fourth spring 271 is connected between the suction frame 27 and the guide rods 26. The front and rear parts of the suction frame 27 are fixedly connected with vertical rods 28. The vertical rods 28 are pressed and engaged with the adjacent spring telescopic rods 25. The suction frame 27 and the sand suction pipe 3 are connected by symmetrical connecting pipes 29. The connecting pipes 29 are flexible hoses to allow the suction frame 27 to move left and right.

[0046] When the accumulated water is discharged into the water tank 1, some of the water will be discharged directly downwards as the mesh frame 6 and mesh plate 8 move to the left. A sludge suction mechanism can be installed to suction the sludge deposited at the bottom of the water tank 1. The specific operation is as follows: When the conveying group 5 drives the mesh frame 6 to rotate, the spring telescopic rod 25 will also rotate. When the spring telescopic rod 25 rotates to contact the vertical rod 28, its continued rotation will push the vertical rod 28 to the right. The rightward movement of the vertical rod 28 will cause the suction frame 27 to slide to the right. The fourth spring 271 will deform, and the suction frame 27 will slide to the right... The sediment deposited at the bottom of water tank 1 is extracted and transported to the sand extraction pipe 3 through the connecting pipe 29. When the suction frame 27 slides to the right to its limit distance, the spring telescopic rod 25 continues to rotate and is squeezed and shortened by the vertical rod 28, thus disengaging from the vertical rod 28. At this time, under the action of the fourth spring 271 resetting, the suction frame 27 slides to the left to reset. When the next set of spring telescopic rods 25 rotates to contact the vertical rod 28, the above action is repeated so that the suction frame 27 can move intermittently left and right to extract the sediment deposited at the bottom of water tank 1, reducing the accumulation of sediment at the bottom of water tank 1.

[0047] like Figure 2 , Figure 13 and Figure 14 As shown, it also includes a pushing mechanism, which can push the mud and sand so that the suction frame 27 can extract it. The pushing mechanism includes a second rack 30, a spiral rod 31, a push plate 32 and a second gear 33. The lower front part of the water tank 1 is fixedly connected with the second rack 30 distributed at equal intervals. The spiral rod 31 is rotatably connected inside the suction frame 27. The push plate 32 is threadedly connected to the spiral rod 31. The push plate 32 is slidably connected to the suction frame 27. The front part of the spiral rod 31 is fixedly connected with the second gear 33, which meshes with the second rack 30.

[0048] By setting up a pushing mechanism, the mud and sand at the bottom of the water tank 1 can be pushed so that the suction frame 27 can extract it. The specific operation is as follows: When the suction frame 27 moves left and right, it will also drive the screw rod 31, the push plate 32 and the second gear 33 to move left or right. Through the movement of the second gear 33 and its meshing with the second rack 30, the screw rod 31 can rotate in both directions when it moves left and right, thereby driving the push plate 32 to slide back and forth and push the mud and sand at the bottom of the water tank 1, causing the mud and sand to surge up so that the suction frame 27 can extract it.
