[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution: a mine sewage treatment and impurity removal device, including a first treatment tank 1, a water inlet pipe 21 is connected to the upper side of the first treatment tank 1, a first filter screen 22 and a second filter screen 23 are connected to the inner side of the first treatment tank 1, the second filter screen 23 is arranged below the first filter screen 22, a discharge port 25 is opened on one side of the first treatment tank 1, a collection tank 24 is connected to one side of the first treatment tank 1, and the collection tank 24 is arranged below the first filter screen 22. A first connecting pipe 26 is connected to the inner side of the first treatment tank 1, a first water pump 27 is arranged on the outer side of the first connecting pipe 26, a treatment mechanism 3 is arranged on one side of the first treatment tank 1, and the treatment mechanism 3 is used to treat sewage. The first treatment tank 1 can play a role in installing and connecting the water inlet pipe 21, and the water inlet pipe 21 can facilitate the staff to add sewage into the first treatment tank 1. The first filter screen 22 can filter larger sundries such as stones, and the filter holes of the second filter screen 23 are smaller than those of the first filter screen 22, which enables the first filter screen 22 to filter finer objects. At the same time, the first filter screen 22 is inclined, so that the stones and other objects filtered on the first filter screen 22 can smoothly slide through the discharge port 25 into the collection tank 24, thereby realizing the collection of sundries and facilitating the subsequent unified treatment of sundries by the staff. The treatment mechanism 3 can re-treat the sewage filtered by the second filter screen 23, so that the sewage can be cleaner after being treated.

[0025] Please refer to Figures 1-5 : The processing mechanism 3 includes a second processing box 31 disposed on one side of the first processing box 1. One end of the first connecting pipe 26 away from the first processing box 1 is connected to the second processing box 31. Inside the second processing box 31, a storage box 32 and a heating plate 33 are connected. The heating plate 33 is disposed below the storage box 32. On one side of the second processing box 31, a third processing box 34 is provided. A fixed pipe 36 is connected between the second processing box 31 and the third processing box 34, and both ends of the fixed pipe 36 are respectively communicated with the second processing box 31 and the third processing box 34. Above the third processing box 34, a water tank 351 is connected. Inside the water tank 351, a circulation pipe 352 is connected, and one end of the circulation pipe 352 penetrates through the third processing box 34. Outside the circulation pipe 352, a first copper plate 353 and a second water pump 354 are connected. The first copper plate 353 is disposed inside the third processing box 34, and the second water pump 354 is disposed above the third processing box 34. Above the water tank 351, a second copper plate 355 is connected;

[0026] In addition, above the second copper plate 355, a fan 356 is connected. The first water pump 27 can, through its own operation, extract the sewage inside the first processing box 1 through the first connecting pipe 26 into the inside of the second processing box 31, so that the sewage that needs to be processed again can smoothly flow into the inside of the storage box 32. The heating plate 33 below the storage box 32 can, through its own operation, heat the sewage inside the storage box 32, and the heated water vapor can smoothly flow into the inside of the third processing box 34 through the fixed pipe 36. While the third processing box 34 plays a role in installing and fixing the fixed pipe 36, it can also connect the circulation pipe 352 and the water tank 351. The inside of the water tank 351 can be used to store the water source needed for cooling, and the second water pump 354 can, through its own operation, make the water source inside the water tank 351 circulate inside the circulation pipe 352. When the water source inside the circulation pipe 352 flows, it can smoothly cool down the water vapor flowing into the inside of the third processing box 34, so that the water vapor can condense into water droplets and be stored inside the third processing box 34;

[0027] In addition, the first copper plate 353 can increase the contact range between the circulation pipe 352 and the water vapor, thereby improving the condensation efficiency. At the same time, the second copper plate 355 can adsorb a certain amount of heat from the water source inside the water tank 351, and through the operation of the fan 356, the temperature of the water source inside the water tank 351 can be reduced. As a result, the temperature of the water source used for cooling inside the water tank 351 is not likely to be too high. The water source stored inside the third treatment tank 34 is formed by condensation, so the water source inside the third treatment tank 34 is relatively clean. The staff can directly use the water source inside the third treatment tank 34, while impurities and fine particles will be retained inside the storage tank 32. Subsequently, the staff only needs to clean the inside of the storage tank 32 to complete the treatment of the sewage.

[0028] Please refer to Figures 1-5 : A heat dissipation plate 41 is connected to the inner side of the water tank 351, and a plurality of heat dissipation plates 41 are provided. A honeycomb groove 42 is opened on one side of the heat dissipation plate 41, and a plurality of honeycomb grooves 42 are opened. The heat dissipation plate 41 can adsorb the temperature of the water source inside the water tank 351, thereby playing a role in cooling the water source inside the water tank 351. The honeycomb groove 42 opened on one side of the heat dissipation plate 41 not only enables the water source inside the water tank 351 to flow smoothly and is not easily blocked by the heat dissipation plate 41, but also can increase the contact area between the water source and the heat dissipation plate 41, thereby improving the heat absorption and cooling effect of the heat dissipation plate 41.

[0029] Please refer to Figures 1-5 : A one-way valve 5 is connected to one side of the second treatment tank 31. The one-way valve 5 is connected to the outside of the fixed pipe 36. The setting of the one-way valve 5 makes the water vapor flowing into the third treatment tank 34 through the fixed pipe 36 not easily flow back into the second treatment tank 31, thereby making the flow of the water vapor more stable and smooth.

[0030] It should be noted that: The outer side of the first filter screen 22 is slidably inserted into the first treatment box 1, the lower side of the water inlet pipe 21 is screwed to the first treatment box 1, one side of the collection box 24 is screwed to the first treatment box 1, the outer sides of the first communication pipes 26 are screwed to the first treatment box 1 and the second treatment box 31 respectively, the inner side of the first water pump 27 is screwed to the first communication pipe 26, the lower side of the storage box 32 is slidably inserted into the second treatment box 31, the outer side of the heating plate 33 is screwed to the second treatment box 31, the outer sides of the fixed pipes 36 are screwed to the second treatment box 31 and the third treatment box 34 respectively, the inner side of the one-way valve 5 is screwed to the fixed pipe 36, the lower side of the water tank 351 is screwed to the third treatment box 34, the outer sides of the flow pipes 352 are screwed to the third treatment box 34 and the water tank 351 respectively, the inner side of the first copper plate 353 is screwed to the flow pipe 352, the lower side of the second water pump 354 is screwed to the third treatment box 34, the inner side of the second water pump 354 is screwed to the third treatment box 34, the lower side of the second copper plate 355 is screwed to the water tank 351, the lower side of the fan 356 is screwed to the second copper plate 355, and the lower side of the heat dissipation plate 41 is screwed to the water tank 351.

[0031] Please refer to Figures 1-5 : A servo motor 61 is connected to one side of the first treatment box 1. The output shaft of the servo motor 61 penetrates the first treatment box 1. The output shaft of the servo motor 61 is connected to a cam 62 through a coupling. The cam 62 is arranged below the first filter screen 22. An installation groove 63 is formed inside the first treatment box 1. A spring 65 is connected inside the first treatment box 1 at the position of the installation groove 63. The lower end of the spring 65 is connected to a fixed block 64. One side of the fixed block 64 is connected to the first filter screen 22. The first treatment box 1 can install and connect the cam 62 through the servo motor 61. When the servo motor 61 operates, it can drive the cam 62 to rotate. When the cam 62 rotates, it can push the first filter screen 22. The first treatment box 1 can connect the spring 65 through the installation groove 63. Since the upper side of the fixed block 64 is connected to the spring 65 and one side of the fixed block 64 is connected to the first filter screen 22, when the first filter screen 22 moves up and down due to pushing, the first filter screen 22 can push the spring 65 through the fixed block 64. When the cam 62 does not push the first filter screen 22, the first filter screen 22 can be reset by its own weight and the pushing of the spring 65. This enables the first filter screen 22 to vibrate the objects and sundries filtered on its upper side through its own up and down movement, so that the sundries and objects can smoothly fall into the collection box 24 and be collected by the collection box 24.

[0032] Please refer to Figures 1-5: A limiting rod 7 is connected inside the mounting groove 63 of the first processing box 1. The limiting rod 7 is connected inside the fixed block 64 and the spring 65. The first processing box 1 can play a role in installing and fixing the limiting rod 7 through the mounting groove 63, while the limiting rod 7 can play a limiting role in the spring 65 and the fixed block 64, making the fixed block 64 move up and down and the spring 65 expand and contract more stably. The fixed block 64 is not prone to deviation, and the spring 65 is also not prone to deformation.

[0033] Please refer to Figures 1-5 : A connecting rod 102 is connected to the lower side of the storage box 32. A connecting groove 101 is provided inside the second processing box 31. The connecting rod 102 is arranged inside the connecting groove 101. The storage box 32 can play a role in installing and fixing the connecting rod 102, while the second processing box 31 can play a limiting role in the connecting rod 102 and the storage box 32 through the connecting groove 101, so that the storage box 32 can be installed or removed stably and conveniently.

[0034] Please refer to Figures 1-5 : A sliding groove 82 is provided inside the first processing box 1. A sliding rod 81 is connected to one side of the second filter screen 23. The sliding rod 81 is arranged inside the sliding groove 82. The second filter screen 23 can install and connect the sliding rod 81. The connection between the sliding rod 81 and the sliding groove 82 makes it convenient for the staff to replace, disassemble and clean the second filter screen 23.

[0035] It should be noted that: One side of the servo motor 61 is screwed to the first processing box 1. One side of the cam 62 is key-connected to the output shaft of the servo motor 61 through a coupling. The upper end of the spring 65 is welded to the first processing box 1 through the mounting groove 63. The lower end of the spring 65 is welded to the fixed block 64. One side of the fixed block 64 is screwed to the first filter screen 22. The outer side of the fixed block 64 is slidably inserted into the first processing box 1 through the mounting groove 63. Both the upper and lower ends of the limiting rod 7 are screwed to the first processing box 1 through the mounting groove 63. The inner side of the fixed block 64 is slidably inserted into the limiting rod 7. The upper side of the connecting rod 102 is screwed to the storage box 32. The outer side of the connecting rod 102 is slidably inserted into the second processing box 31 through the connecting groove 101. One side of the sliding rod 81 is screwed to the second filter screen 23. The outer side of the sliding rod 81 is slidably inserted into the first processing box 1 through the sliding groove 82.

[0036] Working principle: When the utility model is in use, the staff can add sewage into the interior of the first treatment tank 1 through the water inlet pipe 21. Larger objects and sundries in the sewage added into the interior of the first treatment tank 1 will be filtered by the first filter screen 22 and the second filter screen 23 in sequence. Then the staff can start the first water pump 27, and the first water pump 27 can extract the sewage in the interior of the first treatment tank 1, so that the sewage can smoothly flow into the interior of the storage tank 32 through the first connecting pipe 26. At this time, the heating plate 33 can heat the sewage in the interior of the storage tank 32 through its own operation. When the sewage is heated to a certain level, it will turn into water vapor and flow into the interior of the third treatment tank 34 through the fixed pipe 36. At this time, because there is a water source for cooling flowing in the interior of the flow pipe 352, when the water vapor contacts the first copper plate 353 and the flow pipe 352, its temperature will be reduced. After the temperature is reduced, it can condense into water droplets and be stored in the interior of the third treatment tank 34. The impurities and fine particles originally contained in the sewage will remain in the interior of the storage tank 32, and the staff only needs to clean the interior of the storage tank 32 subsequently.

[0037] At the same time, the staff can start the servo motor 61. When the servo motor 61 operates, it will drive the cam 62 to rotate. When the cam 62 rotates, it will push the first filter screen 22. After being pushed, the first filter screen 22 will move upward. After moving, the first filter screen 22 can be reset by its own weight and the elasticity of the spring 65, so as to realize the vibration of the materials on the upper side of the first filter screen 22, so that the materials can smoothly fall into the interior of the collection box 24, which is convenient for collection and subsequent unified treatment.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device.
