[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the features and performances of an integrated mine water purification device in the present invention are further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment 1

[0028] Please see attached Figure 1 and 2 , an integrated mine water purification device, including a coagulation tank 1 for fully mixing mine water with flocculants, a separation sedimentation tank 2 for separating larger sediment particles in water, and a high-efficiency sedimentation tank 3 for separating smaller sediment particles in water.

[0029] The coagulation tank 1 is provided with a baffle plate 11 capable of blocking water flow, which is used to impact and collide with the water flow in the coagulation tank 1 to achieve rapid and full mixing of mine water and flocculant. The coagulation tank 1 is also provided with a flocculant filling device 12, and the outlet of the flocculant filling device 12 is adjacent to the water inlet of the coagulation tank 1.

[0030] In the specific setting, multiple baffles 11 can be set according to the actual size of the coagulation tank 1 to improve the mixing effect. Preferably, in this embodiment, three baffles 11 are set in parallel, and the three baffles 11 are staggered so that the water flow advances along an S-shaped path in the coagulation tank 1 to accelerate the mixing of mine water and flocculant.

[0031] The separation sedimentation tank 2 is in the shape of a funnel with a gradually narrowing bottom. The separation sedimentation tank 2 is provided with a lifting pump 21 for extracting mine water mixed with flocculants from the coagulation tank 1. The outlet of the lifting pump 21 is horizontally arranged at the upper part of the separation sedimentation tank 2 and tangent to the inner wall of the separation sedimentation tank 2, so as to make the water flow spiral down along the funnel-shaped structure under the action of gravity. The separation sedimentation tank 2 is provided with a first mud outlet at the bottom of the funnel shape.

[0032] An overflow cylinder 23 is also provided in the separation sedimentation tank 2. The overflow cylinder 23 is cylindrical. The overflow cylinder 23 is vertically arranged in the separation sedimentation tank 2 and the axis coincides with the axis of the separation sedimentation tank 2. The upper end of the overflow cylinder 23 is above the water surface, and the lower end of the overflow cylinder 23 is lower than the outlet of the lifting pump 21. It is used to separate the mine water that has been preliminarily purified in the central part of the separation sedimentation tank 2.

[0033] During the specific setting, a tangential conduit 22 is provided at the water outlet of the lifting pump 21. The tangential conduit 22 is horizontally arranged on the upper part of the separation sedimentation tank 2 and tangential to the inner wall of the separation sedimentation tank 2. The water discharged from the lifting pump 21 is guided by the tangential conduit 22 and injected into the separation sedimentation tank 2 along the horizontal tangent of the inner wall of the separation sedimentation tank 2.

[0034] The high-efficiency sedimentation tank 3 is provided with a water inlet channel 31, an inclined tube sedimentator 32 and an overflow enclosure 33. The water inlet channel 31 is used to introduce the preliminarily purified water from the separation sedimentation tank 2 into the bottom of the high-efficiency sedimentation tank 3. The inclined tube sedimentator 32 is arranged in the middle of the high-efficiency sedimentation tank 3 to accelerate the descent of fine sediment particles in the water. The overflow enclosure 33 is arranged at the top of the overflow enclosure 33 to discharge the purified clean water at the top of the high-efficiency sedimentation tank 3. The high-efficiency sedimentation tank 3 is provided with a second mud outlet at the bottom.

[0035] In the specific setting, a conveying device 34 is provided between the separation sedimentation tank 2 and the high-efficiency sedimentation tank 3 for conveying the mine water that has been preliminarily purified in the separation sedimentation tank 2 to the high-efficiency sedimentation tank 3. The water inlet end of the conveying device 34 is arranged in the overflow cylinder 23, and the water outlet end of the conveying device 34 is arranged in the water inlet channel 31.

[0036] Preferably, in this embodiment, the conveying device 34 uses a U-shaped pipe with its opening facing downward, the water inlet end of the conveying device 34 is inserted below the water surface in the overflow cylinder 23, the outlet of the conveying device 34 is inserted into the water inlet channel 31, and the horizontal height of the water outlet of the conveying device 34 is lower than the horizontal height of the water inlet, and the water is transferred into the high-efficiency sedimentation tank 3 by using the siphon phenomenon.

[0037] In the specific implementation, untreated mine water is injected into the coagulation tank 1 from the coagulation tank water inlet 13, and the flocculant adding device 12 adds flocculant to the mine water. Due to the presence of the baffle plate 11 in the coagulation tank 1, the mine water added to the coagulation tank 1 flows along the S-shaped waterway under the pumping of the lifting pump 21, accelerating the mixing of the mine water and the flocculant.

[0038] The mine water mixed with flocculant pumped by the lifting pump 21 is injected into the separation sedimentation tank 2 through the tangential conduit 22. Under the guidance of the tangential conduit 22, the mine water enters the separation sedimentation tank 2 along the horizontal tangent of the separation sedimentation tank 2. Under the action of the tank wall, the water flow changes from linear motion to circular motion. Most of the rotating water flow moves downward in a spiral along the tank wall toward the small end of the funnel shape under the action of gravity.

[0039] The sediment particles formed by the flocculant in the mine water are thrown toward the pool wall under the action of centrifugal force. Once the sediment particles come into contact with the pool wall, they lose their inertia and fall along the wall to the bottom. They can be removed regularly through the first mud outlet. The rotating descending clean water part continuously flows into the central part of the separation sedimentation tank 2 during the descent process, forming a centripetal radial water flow and converging in the central part of the separation sedimentation tank 2.

[0040] The conveying device 34 conveys the preliminarily purified mine water collected in the overflow tube 23 to the water inlet channel 31 and enters the bottom of the high-efficiency sedimentation tank 3. The water flows upward from the bottom of the high-efficiency sedimentation tank 3, and the fine sediment remaining in the water falls down to the bottom of the tank after passing through the inclined tube sedimentator 32, and can be removed regularly through the second mud outlet. After the clean water purified by the tube sedimentator 32 overflows through the overflow enclosure 33, it is discharged from the high-efficiency sedimentation tank outlet 35, and the purification process is completed.

[0041] Embodiment 2

[0042] Different from the first embodiment, in the second embodiment, the conveying device 34 adopts a water pump, so as to adapt to the overall purification speed of the water purification device to a greater extent.

[0043] It should be noted that the parts not described in detail in this scheme are all prior art, and the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model fall within the protection scope of the present utility model.
