[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] according to Figure 1 、 2 As shown in Figures 3 and 4, a drainage dredging device for a coal mine is proposed in this embodiment, comprising a water trough 1, in which a flow pool 2 and a cleaning pool 3 are provided. The flow pool 2 and the cleaning pool 3 are separated by a baffle 4, which is fixedly connected to the inner side of the water trough 1;

[0024] A second filter plate 8 is provided in the overflow pool 2. The second filter plate 8 is hinged to the upper end of the baffle 4 on one side thereof close to the baffle 4. The lower end surface of the other side of the second filter plate 8 is engaged with a locking member provided on the inner side of the water tank 1. The upper end surface of the other side of the second filter plate 8 is fixedly connected to the first filter plate 7. The first filter plate 7 is provided at an oblique angle.

[0025] The accumulated water flowing into the water tank 1 will first pass through the first filter plate 7, which will block the large pieces of water in the accumulated water. When the accumulated water containing gravel passes through the second filter plate 8, the second filter plate 8 will filter out the gravel in the accumulated water. By setting the dual filtration mode, it is ensured that the accumulated water will not block the drain pipe 5 when it is discharged, thereby ensuring the normal operation of the drainage system.

[0026] A turnover mechanism for rotating the second filter plate 8 is provided on the outside of the water tank 1 , and a positioning member for limiting the rotation of the second filter plate 8 is provided on the turnover mechanism.

[0027] The second filter plate 8 is mounted on the water inlet of the flow tank 2 in a snap-fit ​​manner. The second filter plate 8 is driven to rotate by the flipping mechanism, and the second filter plate 8 is flipped into the cleaning tank 3. The attachments on the inner sides of the first filter plate 7 and the second filter plate 8 will fall into the cleaning tank 3 by themselves. The first filter plate 7 and the second filter plate 8 can be backflushed with a water pipe, which makes it easy to dredge and clean the first filter plate 7 and the second filter plate 8.

[0028] About the flip mechanism:

[0029] The flipping mechanism includes a rotating shaft 13, which is rotatably connected to the outside of the water tank 1. The end of the rotating shaft 13 close to the water tank 1 penetrates into the water tank 1 and is fixedly connected to the second filter plate 8. The other end of the rotating shaft 13 is fixedly connected to a rocker 14, and the end of the rocker 14 away from the rotating shaft 13 is rotatably connected to a rubber handle.

[0030] The rotating shaft 13 is fixedly connected to the end of the second filter plate 8 near the baffle 4, that is, the hinge between the second filter plate 8 and the baffle 4. When the rocker 14 is turned from the outside of the water tank 1, the rocker 14 will rotate the second filter plate 8 through the rotating shaft 13. The rubber handle makes it easier to hold the rocker 14.

[0031] To prevent the second filter plate 8 from shaking during flushing, when the second filter plate 8 is stuck in the overflow tank 2 or transferred to the cleaning tank 3, the positioning member will restrict the rotation of the second filter plate 8 from the outside of the water tank 1, thereby improving the flushing stability of the second filter plate 8. Specifically, the positioning member includes a positioning ring 15, which is sleeved on the outside of the rotating shaft 13. The positioning ring 15 is fixedly connected to the rotating shaft 13. A threaded seat 18 is provided in the circumferential direction of the axis of the positioning ring 15. The threaded seat 18 is fixedly connected to the outside of the water tank 1. An adjusting bolt 17 is threadedly connected to the threaded seat 18. The adjusting bolt 17 passes through the threaded seat 18 and is threadedly connected to a threaded hole 16 provided on the outside of the positioning ring 15.

[0032] By rotating the rotating shaft 13, the second filter plate 8 will rotate accordingly. When the second filter plate 8 is closed in the overflow tank 2 or completely turned over into the cleaning tank 3, the axis of the threaded hole 16 on the outer side of the positioning ring 15 will be in a coincident state with the axis of the adjusting bolt 17. By rotating the adjusting bolt 17 and screwing it into the threaded hole 16, the rotation of the positioning ring 15 can be restricted. Since the rotation of the positioning ring 15 is restricted, the rotation of the rotating shaft 13 and the second filter plate 8 will also be restricted.

[0033] Furthermore, a plurality of threaded holes 16 are formed on the outside of the positioning ring 15, and the threaded holes 16 are evenly arranged in the circumferential direction of the axis of the positioning ring 15. By rotating the adjustment bolts 17 and screwing the adjustment bolts 17 into the corresponding threaded holes 16, the second filter plate 8 can be suspended to any angle, and the second filter plate 8 can be positioned flexibly.

[0034] About the snap-on parts:

[0035] The engaging member includes a stopper 6 disposed inside the overflow tank 2. The stopper 6 is fixedly connected to the overflow tank 2. A slot 11 is defined at the top of the stopper 6. The slot 11 engages with a spherical snap 10 disposed on the lower end surface of the second filter plate 8. The spherical snap 10 is fixedly connected to the side of the second filter plate 8 away from the baffle 4. When the second filter plate 8 falls into the overflow tank 2, the side of the second filter plate 8 away from the baffle 4 contacts the stopper 6. The stopper 6 supports the second filter plate 8 from its bottom. At this point, the spherical snap 10 on the second filter plate 8 also engages with the slot 11, limiting the position of the second filter plate 8 without affecting its opening.

[0036] To facilitate the drainage of accumulated water, a drain pipe 5 and two mud pipes 9 are installed at the bottom of the water tank 1. The drain pipe 5 is connected to the overflow tank 2, and the two mud pipes 9 are connected to the overflow tank 2 and the cleaning tank 3 respectively. The drain pipe 5 is placed above the mud pipes 9. The mud pipes 9 are installed at the bottom of the overflow tank 2 and the cleaning tank 3. The sludge in the accumulated water will settle at the bottom of the overflow tank 2 and the cleaning tank 3 and will not be discharged with the opening of the drain pipe 5. A mud pump is connected to the mud pipe 9 to clean the sludge at the bottom of the overflow tank 2 and the cleaning tank 3. The valve between the mud pipe 9 and the water tank 1 can be opened.

[0037] To reduce the structural strength of the first filter plate 7, in a preferred embodiment, a diagonal brace 12 is provided between the first filter plate 7 and the second filter plate 8, with both ends of the diagonal brace 12 fixedly connected to the first filter plate 7 and the second filter plate 8. The diagonal brace 12 is provided between the first filter plate 7 and the second filter plate 8 to support the first filter plate 7, thereby improving the impact resistance of the first filter plate 7 and preventing the connection between the first filter plate 7 and the second filter plate 8 from breaking.

[0038] Working principle:

[0039] The accumulated water flowing into the water tank 1 will first pass through the first filter plate 7, which will block the large blocks in the accumulated water. When the accumulated water containing sand and gravel passes through the second filter plate 8, the second filter plate 8 will filter out the sand and gravel in the accumulated water. The second filter plate 8 is arranged at the water inlet of the flow pool 2 in a snap-fit ​​manner, and the second filter plate 8 is driven to rotate by the flipping mechanism. The second filter plate 8 and the second filter plate 8 will flip into the cleaning pool 3. The attachments on the inner sides of the first filter plate 7 and the second filter plate 8 will fall into the cleaning pool 3 by themselves. The first filter plate 7 and the second filter plate 8 can be backflushed with a water pipe, and the first filter plate 7 and the second filter plate 8 are easy to dredge and clean.
