[0001] The utility model relates to the technical field of sewage treatment in coal mines, in particular to a device for separating and discharging gushing water, cleaning and sewage from underground mines. Background Art

[0002] At present, when coal mines are operating underground, all the gushing water, including the clear water from the old pond in the goaf area of ​​the coal mine and the construction sewage from the mining face, will be gathered into the same main water tank underground and then discharged to the ground. In the process of mine water flowing into the water tank, it will carry a large amount of coal powder, coal blocks and other impurities and settle at the bottom of the water tank, forming silted coal slime. The silted coal slime is a high-viscosity, paste-like solid-liquid two-phase flow.

[0003] The utility model with the announcement number CN220081502U proposes a coal mine underground water gushing, cleaning and sewage separation and discharge system, which relates to the technical field of coal mine underground sewage treatment. The discharge system includes a sewage generating end of the coal mining and excavation working face, a clean water generating end of the goaf area, a central No. 1 water storage tank, a central No. 2 water storage tank, a ground sewage treatment station workshop and a ground clean water station opening workshop. The sewage generating end of the coal mining and excavation working face, the central No. 1 water storage tank and the ground sewage treatment station workshop are set as one discharge passage, and the clean water generating end of the goaf area, the central No. 2 water storage tank and the ground clean water station opening workshop are set as another discharge passage, which can realize the division of the two sets of underground main drainage systems, separate all the underground sewage and clean water through pipelines, and finally discharge them into the central No. 1 water storage tank and the central No. 2 water storage tank respectively. In the later maintenance, it is only necessary to arrange the cleaning construction in the central No. 1 water storage tank, and the water in the central No. 2 water storage tank can be directly discharged to the ground for secondary utilization.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. Sediment is easily formed in the central No. 2 water storage tank used for circulating sewage. When the sediment is formed, the upper layer of the sediment is clean water. During drainage, this part of the clean water is transferred by the water pump to the ground sewage treatment station workshop for treating sewage, thereby increasing the ineffective workload of the ground sewage treatment station workshop; 2. Sediment is easily formed in the central No. 2 water storage tank used for circulating sewage. This part of the sediment is difficult to discharge, and is usually discharged by manual excavation. Some are discharged by sludge pumps, but the sludge pump is easily damaged due to the large flow resistance of the sediment.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3The utility model provides a technical solution: a device for separating and discharging underground water and sewage from a mine, comprising an underground clean water tank 1 and an underground sewage tank 2. The underground clean water tank 1 is used to collect clean water formed at the clean water generating end of the goaf, and the underground sewage tank 2 is used to collect sewage formed at the sewage generating end of the coal mining and excavation working face. The underground clean water tank 1 and the underground sewage tank 2 start the function of a turnover tank. The bottoms of the underground clean water tank 1 and the underground sewage tank 2 are both provided with a pumping pipe 101, and a pumping pump 9 is connected in series to the pumping pipe 101. The clean water in the underground clean water tank 1 is transmitted to the workshop of the ground clean water treatment station through the corresponding pumping pump 9, and the clean water in the underground sewage tank 2 is transmitted to the workshop of the ground sewage treatment station through the corresponding pumping pump 9, so as to realize clean and sewage separation and discharge.

[0023] In the present technical solution, a transmission pipe 3 near the mouth of the underground clean water tank 1 and the underground sewage tank 2 is connected in series, the mouth here is the top, and the bottom of the transmission pipe 3 is fixedly connected with a clean water down pipe 31 located in the underground clean water tank 1 and a clean water up pipe 32 located in the underground sewage tank 2, and the height of the lower end of the clean water up pipe 32 is higher than the height of the lower end of the clean water down pipe 31. Preferably, the inner diameter of the clean water down pipe 31 is larger than the inner diameter of the clean water up pipe 32. The clean water up pipe 32 introduces the clean water on the upper layer of the sediment in the underground sewage tank 2 into the underground clean water tank 1 through the transmission pipe 3, so as to prevent the clean water and sediment in the underground sewage tank 2 from participating in the sewage treatment.

[0024] Furthermore, the mouths of the clean water upper pipe 32 and the clean water lower pipe 31 are both provided with gates 4, and the function of the gates 4 is to enable the transmission pipe 3, the clean water upper pipe 32 and the clean water lower pipe 31 to form a siphon effect to transmit clean water. Among them, the transmission pipe 3 is provided with a control mechanism 5 for synchronously opening and closing the gates 4 at the bottom of the clean water upper pipe 32 and the clean water lower pipe 31.

[0025] Specifically, the control mechanism 5 includes a cylinder 51 and a gantry frame 52. The two vertical rods 521 on the gantry frame 52 are respectively slidably matched with the outer side walls of the clean water upper pipe 32 and the clean water lower pipe 31. One side of the two vertical rods 521 is fixedly connected to the outer peripheral wall of the connecting rod and the gate plate 4 respectively. The cylinder 51 is fixedly arranged on the top of the transmission pipe 3 and its actuating end is fixedly connected to the crossbeam 522 on the gantry frame 52. The cylinder 51 provides driving force for the lifting and lowering of the gantry frame 52. When the bottom of the clean water upper pipe 32 and the clean water lower pipe 31 are blocked by the gate plate 4, a certain amount of water is stored at both ends of the clean water lower pipe 31. Then, when the gate plate 4 is controlled to be opened, the clean water in the clean water lower pipe 31 drops to form a siphon.

[0026] In this embodiment, the top of the gate 4 is fixedly connected to a transmission shaft 41, and the top of the transmission shaft 41 adjacent to the clean water upper water pipe 32 is fixedly connected to a water supply piston disc 6, and the water supply piston disc 6 is sealed with the inner circumferential wall of the clean water upper water pipe 32, and the top of the transmission shaft 41 adjacent to the clean water lower water pipe 31 is fixedly connected to a water discharge piston disc 7, and the water discharge piston disc 7 is sealed with the inner circumferential wall of the clean water lower water pipe 31, wherein the arrangement of the water supply piston disc 6 and the water discharge piston disc 7 can ensure the sealing effect of the clean water upper water pipe 32 and the clean water lower water pipe 31, making the siphon more reliable.

[0027] Furthermore, a water window 321 close to the bottom is provided on the outer wall of the clean water supply pipe 32, and a filter net 8 is arranged in the water supply window 321. The function of the filter net 8 is to prevent the sediment in the underground sewage tank 2 from entering the clean water supply pipe 32, thereby filtering the sewage and ensuring that the water entering the transmission pipe 3 is clean water.

[0028] In this embodiment, the control mechanism 5 also includes a stirring shaft 53 and a control motor 54. The stirring shaft 53 is rotatably connected to the cross beam 522 and its bottom is fixedly connected to a stirring blade 531 located in the underground sewage tank 2. The control motor 54 is fixedly arranged on the top of the cross beam 522 and its output shaft is fixedly connected to the top of the stirring shaft 53. When the stirring shaft 53 rotates, the stirring blade 531 stirs the sediment and part of the clean water on the upper layer of the sediment, so that the sediment is diluted faster, which facilitates the discharge of the water pump 9 and reduces the load of the water pump 9.

[0029] Working principle: When in use, when the amount of clean water and sewage in the underground clean water tank 1 and the underground sewage tank 2 reaches a certain water level, the gate 4 is controlled to open, so that a certain amount of water enters the clean water down pipe 31 and the clean water up pipe 32, and then the gate 4 is closed, and the pump 9 connected to the underground clean water tank 1 is started, and the clean water is uploaded to the workshop of the ground clean water treatment station, and then further purified. After the clean water in the underground clean water tank 1 is discharged, the control cylinder 51 is driven to drive the door frame 52 to descend, the two gates 4 are lowered, and the water up piston disc 6 and the water down piston disc 7 leave the clean water up pipe 32 and the clean water down pipe 31 at the same time. At this time, the water volume in the clean water down pipe 31 is large to form a siphon, and most of the clean water on the upper layer of the sediment in the underground sewage tank 2 is transferred to the underground clean water tank 1, reducing the content of clean water in the underground sewage tank 2. Then the control motor 54 is started, the stirring shaft 53 drives the stirring blade 531 to stir the sediment, accelerate the dilution of the sediment, and then the pump 9 connected to the underground sewage tank 2 is started to transfer the diluted sediment to the workshop of the ground sewage treatment station, thereby achieving the separation and discharge of sewage.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
