DETAILED DESCRIPTION

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figure 1-5As shown, the sewage treatment device used in the open-pit coal mine of the embodiment of the present invention includes a first sewage tank 1, a second sewage tank 2, a first drive assembly 3 and a second drive assembly 4. The upper end of the side wall of the first sewage tank 1 has a first connecting hole 11, and the first connecting hole 11 is connected to the inner cavity of the first sewage tank 1. The upper end of the side wall of the second sewage tank 2 has a second connecting hole 21, and the second connecting hole 21 is connected to the inner cavity of the second sewage tank 2. The first connecting hole 11 and the second connecting hole 21 are connected so that the inner cavity of the first sewage tank 1 is connected to the inner cavity of the second sewage tank 2. A first bottom plate 12 is movably provided in the first sewage tank 1, and the outer peripheral contour of the first bottom plate 12 is adapted to the inner peripheral contour of the first sewage tank 1. A second bottom plate 22 is movably provided in the second sewage tank 2, and the outer peripheral contour of the second bottom plate 22 is adapted to the inner peripheral contour of the second sewage tank 2.

[0033] The first driving assembly 3 is disposed on the first sewage pool 1 and connected to the first bottom plate 12, and is used to drive the first bottom plate 12 to move in the first sewage pool 1 in the up-down direction, so that the sewage in the first sewage pool 1 can flow into the second sewage pool 2 through the first connecting hole 11. The second driving assembly 4 is disposed on the second sewage pool 2 and connected to the second bottom plate 22, and is used to drive the second bottom plate 22 to move in the second sewage pool 2 in the up-down direction, so that the sewage in the second sewage pool 2 can flow into the first sewage pool 1 through the second connecting hole 21.

[0034] Specifically, the sewage is preliminarily precipitated in the first sewage tank 1, and the sewage in the first sewage tank 1 is introduced into the second sewage tank 2 for further precipitation, so that finer impurities in the sewage continue to be precipitated in the second sewage tank 2, so that the first sewage tank 1 and the second sewage tank 2 can carry out different treatment processes at the same time, thereby improving the working efficiency of the sewage treatment device.

[0035] Seals (not shown) are provided between the first bottom plate 12 and the first sewage pool 1 and between the second bottom plate 22 and the second sewage pool 2 to prevent sewage from leaking out of the gaps between the bottom plates and the sewage pools.

[0036] In the sewage treatment device used in the open-pit coal mine of the embodiment of the present invention, the first driving component 3 moves the first bottom plate 12 to slowly raise the sewage in the first sewage pool 1 to the top, so as to enter the second sewage pool 2 through the first connecting hole 11 and the second connecting hole 21. Moreover, during the movement of the first bottom plate 12, the coal ash on the inner wall surface of the first sewage pool 1 can also be scraped off to clean the inner wall surface of the first sewage pool 1. The rising of the first bottom plate 12 facilitates the operator to clean the sediment on the first bottom plate 12. Compared with the prior art, the operator needs to enter the sewage pool to clean the sediment, which effectively saves manpower and material resources. At the same time, the sewage entering the second sewage pool 2 can continue to precipitate in the second sewage pool 2, ensuring the normal operation of the sewage treatment device and ensuring the operation efficiency. Similarly, the second driving component 4 can also move the second bottom plate 22 to slowly raise the sewage in the second sewage pool 2 to the top, so as to enter the first sewage pool 1 through the second connecting hole 21 and the first connecting hole 11.

[0044] Specifically, the first connecting member 31 is installed on the side wall of the first sewage tank 1 through the card slot 314, and the installation method is simple. The motor 321 drives the gear 323 to rotate through the rotating rod 322, and the gear 323 engages with the tooth groove 3131 on the first sliding plate 313, so that the first sliding plate 313 moves in the up and down direction under the action of the gear 323, and the first sliding plate 313 drives the first transition plate 312 and the first connecting plate 311 to move in the up and down direction, and then drives the first bottom plate 12 to move in the up and down direction. The moving method of the first connecting member 31 is simple and easy to operate. Similarly, the second connecting member 41 has the same structure as the first connecting member 31 and the same working principle.

[0045] In some embodiments, the first driving assembly 3 further includes a first fixed shell 33, which is disposed on the outer side of the first sewage pool 1. The first fixed shell 33 has a first installation cavity 331, a first channel 332 and a first movable cavity 333.

The motor 321 is disposed in the first installation cavity 331, the rotating rod 322 is disposed in the first channel 332, and the gear 323 is disposed in the first movable cavity 333. By providing the first fixed shell 33, the first connecting member 31 is waterproofed, the first connecting member 31 is protected from damage by external forces, and the service life of the first connecting member 31 is extended.

[0046] The outer side surface of the first sewage tank 1 has a first slide groove 13 , which extends in the up-down direction. The first movable cavity 333 is connected to the first slide groove 13 , and the first sliding plate 313 is slidably installed in the first slide groove 13 .

[0047] Specifically, there are multiple first chutes 13, and the multiple first chutes 13 are evenly arranged around the circumference of the first sewage tank 1, and the multiple first chutes 13 correspond to the multiple first drive components 3 one by one. The first chutes 13 are formed by being recessed from the outer side of the first sewage tank 1 to the inner side of the first sewage tank 1, and the first sliding plate 313 is slidably installed in the first chutes 13, which can limit the first sliding plate 313, ensuring that the first sliding plate 313 can move along the extension direction of the first chutes 13, thereby ensuring the stability of the first bottom plate 12 during the movement. Similarly, the outer side of the second sewage tank 2 has a second chute 23.

[0048] In some embodiments, the sewage treatment device used in the open-pit coal mine further includes a first water inlet pipe 51, a second water inlet pipe 52, a water guide pipe 53, a first water inlet valve 54, and a second water inlet valve 55. One end of the first water inlet pipe 51 is connected to the first sewage pool 1, one end of the second water inlet pipe 52 is connected to the second sewage pool 2, the other end of the first water inlet pipe 51 is connected to the other end of the second water inlet pipe 52 and both are connected to one end of the water guide pipe 53, and water can be introduced into the water guide pipe 53 through the other end of the water guide pipe 53.

[0049] Specifically, when the operator opens the first water inlet valve 54 and closes the second water inlet valve 55, the sewage can enter the first sewage pool 1 through the water pipe 53 and the first water inlet pipe 51 and be precipitated in the first sewage pool 1. Conversely, if the operator opens the second water inlet valve 55 and closes the first water inlet valve 54, the sewage can enter the second sewage pool 2 through the water pipe 53 and the second water inlet pipe 52 and be precipitated in the second sewage pool 2. The operation process is simple and easy to control.

[0050] In some embodiments, the sewage treatment device used in the open-pit coal mine further includes a first drain pipe 61, a second drain pipe 62, a water pipe 63, a first drain valve 64, and a second drain valve 65.

The first drain valve 64 is arranged in the first drain pipe 61, and is used to control the opening and closing of the first drain pipe 61, and the second drain valve 65 is arranged in the second drain pipe 62, and is used to control the opening and closing of the second drain pipe 62.

[0051] Specifically, when the operator opens the first drain valve 64 and closes the second drain valve 65, the sewage precipitated in the first sewage pool 1 can be discharged through the first drain pipe 61 and the water pipe 63. Conversely, if the operator opens the second drain valve 65 and closes the first drain valve 64, the sewage precipitated in the second sewage pool 2 can be discharged through the second drain pipe 62 and the water pipe 63. The operation process is simple and easy to control.

[0052] In some embodiments, the sewage treatment device used in open-pit coal mine mining further includes a first filter screen 71 , and the first filter screen 71 is disposed at one end of the first drainage pipe 61 and one end of the second drainage pipe 62 .

[0053] Specifically, when the first bottom plate 12 of the first sewage pool 1 rises under the action of the first driving assembly 3, the sewage in the first sewage pool 1 can be discharged through the first drain pipe 61, and the first filter net 71 can filter the smaller fixed garbage in the first sewage pool 1 into the first sewage pool 1. The first filter net 71 is a fine-mouth filter net.

[0057] Specifically, when the first bottom plate 12 is driven to rise in the first sewage pool 1 by the first driving assembly 3 , the settled water in the first sewage pool 1 enters the second sewage pool 2 through the connecting pipe 8 .

[0058] The working principle and use process of the sewage treatment device used in open-pit coal mine mining according to the embodiment of the present invention are as follows:

[0059] When it is necessary to clean the sediment in the first sewage tank 1, first start the motor 321. The motor 321 drives the gear 323 to rotate through the rotating rod 322. The gear 323 and the tooth groove 3131 are engaged, so that the first connecting member 31 drives the first bottom plate 12 to rise, so that the sewage inside the first sewage tank 1 slowly rises to the top. The sewage in the first sewage tank 1 enters the connecting pipe 8 through the second filter screen 72 and is introduced into the second sewage tank 2 through the connecting pipe 8. During this process, the first bottom plate 12 can scrape off the coal ash on the inner wall of the first sewage tank 1, which is convenient for the operator to clean the sediment on the surface of the first bottom plate 12. The operation is simple, saving time and effort.

[0060] When the sewage needs to be continuously precipitated, the operator can open the first water inlet valve 54 and close the second water inlet valve 55. The sewage is introduced into the first sewage pool 1 through the water pipe 53 and the first water inlet pipe 51 for precipitation. After that, the operator opens the first drain valve 64 and closes the second drain valve 65, so that the precipitated sewage in the first sewage pool 1 passes through the first filter net 71 into the first drain pipe 61, and then is discharged through the water pipe 63.

[0061] Similarly, when the operator closes the first water inlet valve 54 and opens the second water inlet valve 55, the sewage can enter the second sewage pool 2 for sedimentation. When the operator closes the first drain valve 64 and opens the second drain valve 65, the sewage precipitated in the second sewage pool 2 passes through the first filter screen 71 into the second drain pipe 62, and then is discharged from the water pipe 63, so that the sewage treatment device can achieve the purpose of continuous operation.
