[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1 and Figure 2 As shown, the utility model comprises a containing box 3 mounted on a support rod 5, and the containing box 3 is fixed on a base 6 through the support rod 5. A cover plate 2 is provided on the top of the containing box 3, and a guide pipe 1 is connected to the top of the containing box 3, and the guide pipe 1 is connected to the top of the cover plate 2.

[0029] The side wall of the accommodating box 3 is provided with two upper and lower drainage holes 17, the upper drainage hole 17 is connected to the first drainage pipe 8, and the lower drainage hole 17 is connected to the second drainage pipe 9. The base 6 is also provided with a fixing frame 7 for fixing the first drainage pipe 8 and the second drainage pipe 9. The utility model provides two drainage pipes, thereby sharing the pressure of the water flow when a single drainage pipe is used, improving the water flow bearing capacity of the drainage system, effectively preventing the drainage pipe from rupturing due to excessive pressure, reducing the failure of the drainage system, and reducing the safety hazards of mine production.

[0030] The receiving box 3 is also provided with a filter screen 10 between the guide pipe 1 and the upper drainage hole 17. By providing the filter screen 10, not only can the water discharged to the receiving box 3 be filtered, but also the debris in the water of the receiving box 3 can be prevented from accumulating on the filter screen 10 and causing blockage, which can effectively ensure the working efficiency of the drainage system; and the filter screen 10 is easy to remove and clean, and convenient for maintenance.

[0031] The accommodating box 3 is also provided with a piston-type sealing plate 11 which can move up and down, and the piston-type sealing plate 11 is located between the upper and lower drainage holes 17. The bottom of the piston-type sealing plate 11 is connected with two guide rods 13.

[0032] The utility model also includes a limiting mechanism for limiting the up and down movement stroke of the piston type sealing plate 11.

[0033] Combination Figure 3 and Figure 4 As shown, the guide rod 13 passes through the guide hole 14 on the bottom plate of the accommodating box 3.

[0034] The bottom of the housing box 3 is also provided with an elastic reset mechanism for supporting the piston-type sealing plate 11, and the elastic reset mechanism is specifically a spring 18. The spring 18 is sleeved on the guide rod 13, and the upper end is in contact with the piston-type sealing plate 11 and the lower end is in contact with the bottom plate of the housing box 3. By providing the elastic reset mechanism, the height of the sealing plate 11 can be adjusted according to the size of the water flow, thereby adjusting the drainage volume in each drainage pipe, and the second drainage pipe 9 is not used too much, thereby reducing the number of inspections of the second drainage pipe 9 and reducing the maintenance cost of the second drainage pipe 9; and the device has good adaptability and can ensure the normal operation of the drainage system.

[0035] The limiting mechanism includes a limiting plate 4 fixed on the support rod 5, and also includes an adjusting rod 12 whose upper end is fixedly connected to the piston-type sealing plate 11, and the lower end of the adjusting rod 12 sequentially passes through a first through hole 15 on the bottom plate of the containing box 3 and a second through hole 16 on the limiting plate 4. The adjusting rod 12 is provided with an external thread, and a first nut 19 and a second nut 20 respectively located on the upper and lower sides of the limiting plate 4 are installed on the external thread.

[0036] like Figure 5 As shown, the filter screen 10 is fixed in the accommodating box 3 via a connecting frame 21 .

[0037] The utility model discloses a mining sewage treatment equipment which is convenient for graded drainage, and its use method is as follows:

[0038] When there is no water flow, the spring 18 is not compressed, the adjusting rod 12 is stationary, the first nut 19 is away from the limiting plate 4, the second nut 20 is in close contact with the limiting plate 4, the sealing plate 11 is stationary, and the sealing plate 11 is located on the upper side of the drainage hole 17 below.

[0039] When water flows from the flow guide pipe 1 into the containing box 3 , it is first filtered by the filter screen 10 and then falls onto the sealing plate 11 .

[0040] When the water flow is small, the water pressure slightly compresses the spring 18 to a certain extent, causing the adjusting rod 12 to move slightly downward, the first nut 19 to not contact the limit plate 4, and the second nut 20 to be slightly away from the limit plate 4. At the same time, the sealing plate 11 moves slightly downward, and the displacement of the sealing plate 11 does not reach the point where the drainage hole 17 below is completely exposed. At this time, the water flow is mainly discharged through the first drain pipe 8, and a small amount will be discharged from the second drain pipe 9 with a slight increase.

[0041] When the water flow rate increases sharply, the water pressure compresses the spring 18 suddenly to the maximum limit, causing the adjusting rod 12 to move downward rapidly, the first nut 19 to be tightly attached to the limit plate 4, and the second nut 20 to be away from the limit plate 4. At the same time, the sealing plate 11 moves downward rapidly to the maximum limit, and the sealing plate 11 is located on the lower side of the lower drainage hole 17. At this time, water flows out from the first drain pipe 8 and the second drain pipe 9 at the same time.

[0042] In addition, the displacement range of the sealing plate 11 can be controlled by adjusting the positions of the first nut 19 and the second nut 20 on the adjusting rod 12 .
