This mine wastewater treatment device effectively filters large particulate impurities after precipitation through the filter mesh plate arranged at the position corresponding to the filtering device, and effectively improves the reaction rate between uranium-containing wastewater and chemical reagents through the supporting rotating member arranged on the mounting plate. At the same time, it prevents some large particulate impurities from floating on the surface of the wastewater and affecting the flocculation effect of the wastewater. And when the storage barrel discharges the sediment, the supporting rotating member can play a role in dredging the discharge of the sediment and prevent the sediment from blocking at the discharge pipe.

[0004] The treatment pool in this patent is not provided with a dosing device. When adding medicine for treatment, the medicine can only be poured into the storage barrel, so there will be a situation where the wastewater and the medicine are not evenly mixed. Content of the Utility Model

The first motor drives the traveling wheels to rotate to realize the horizontal movement of the frame; through the rotation of the stirring rod, the wastewater is stirred.

[0032] The following is a further description of the present utility model in conjunction with the attached Figures 1 - 10 drawings.

[0033] Embodiment 1

[0034] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: A mine wastewater treatment device includes a treatment tank 1. A frame 4 is arranged inside the treatment tank 1. First motors 5 are fixedly connected to both ends of the frame 4. The output ends of the first motors 5 are fixedly connected with traveling wheels 6. Guide rails 2 are fixedly connected to both sides outside the treatment tank 1. The traveling wheels 6 are located in the guide rails 2. The first motors 5 drive the traveling wheels 6 to rotate, so as to realize the linear movement of the frame 4.

[0035] In a further design, a second motor 7 is fixedly connected to the top of the frame 4. The output end of the second motor 7 is fixedly connected to a stirring rod 8. The second motor 7 drives the stirring rod 8 to rotate to stir the wastewater. An installation ring 37 is fixedly connected to the top of the frame 4. A rotating plate 9 is rotatably connected to the outside of the installation ring 37. A storage cylinder 14 is fixedly connected to the rotating plate 9. The storage cylinder 14 stores treatment chemicals. A discharge pipe 32 is fixedly connected to the bottom of the storage cylinder 14. A valve plate 35 is slidably connected through the discharge pipe 32. A reciprocating feeding assembly for driving the rotating plate 9 to reciprocate is provided on the frame 4.

[0036] Wherein, piston boxes 30 are fixedly connected to both ends of the discharge pipe 32. A piston block 33 is slidably connected in the piston box 30. A pull rod 34 is fixedly connected between the piston block 33 and the valve plate 35. The pull rod 34 is used to pull the valve plate 35 to slide.

[0037] In a further design, a fixing plate 24 is fixedly connected to the outside of the frame 4. A guide rod 25 is slidably connected through the fixing plate 24. The top of the guide rod 25 is fixedly connected to a lifting plate 26. A piston cylinder 28 is fixedly connected to the piston box 30. A piston column 36 is slidably connected in the piston cylinder 28. The top of the piston column 36 is fixedly connected to a piston rod 29. One end of the piston rod 29 is fixedly connected to the lifting plate 26.

[0038] Wherein, a third electromagnet 27 is fixedly connected to the lifting plate 26. Two arc-shaped frames 16 are fixedly connected to the frame 4. A first electromagnet 17 is fixedly connected to the arc-shaped frame 16. The first electromagnet 17 and the third electromagnet 27 are arranged with opposite poles attracting each other.

[0039] In addition, two vertical frames 18 are fixedly connected to the frame 4. A second electromagnet 19 is fixedly connected to the vertical frame 18. The second electromagnet 19 and the third electromagnet 27 are arranged with the same poles repelling each other. The second electromagnet 19 is used to repel the third electromagnet 27 with the same poles to make the lifting plate 26 move downward to reset.

[0040] In a further design, in this embodiment, the provided reciprocating feeding assembly includes a gear ring 10 fixedly connected to the outside of the rotating plate 9, a fixing frame 13 fixedly connected to the outside of the frame 4, a gear 11 rotatably connected to the fixing frame 13, and a cylinder 12 fixedly connected to the outside of the fixing frame 13. The piston rod 29 of the cylinder 12 is fixedly connected to a rack 15. The cylinder 12 drives the rack 15 to perform a reciprocating motion, which will drive the rack 15 to perform a reciprocating movement. The rack 15 drives the gear 11 to rotate reciprocally. The gear 11 drives the gear ring 10 to rotate reciprocally. The gear ring 10 drives the rotating plate 9 to rotate reciprocally. The rotating plate 9 drives the storage cylinder 14 to perform a reciprocating left and right rotation.

[0041] For those skilled in the art to fully understand the technical solution, the following explanations are made in this embodiment:

[0042] The wastewater is conveyed into treatment tank 1, and the first motor 5 and the second motor 7 are started to work. The first motor 5 drives the traveling wheels 6 to rotate, so as to realize the movement of the frame 4 on the treatment tank 1. The second motor 7 drives the stirring rod 8 to rotate to stir the wastewater. In addition, a large amount of wastewater treatment agents are stored in the storage cylinder 14.

[0043] During the linear movement of the frame 4, the air cylinder 12 is started to drive the rack 15 to move reciprocally. The rack 15 drives the gear 11 to rotate reciprocally. The gear 11 drives the toothed ring 10 to rotate reciprocally. The toothed ring 10 drives the rotating plate 9 to rotate reciprocally. The rotating plate 9 drives the storage cylinder 14 to rotate reciprocally left and right.

[0044] The further explanations are as follows:

[0045] For example, when the rotating plate 9 rotates leftward by a certain angle, the first electromagnet 17 corresponds to the third electromagnet 27. The first electromagnet 17 and the second electromagnet 19 attract each other with opposite polarities, thus driving the left lifting plate 26 to move upward. After the left lifting plate 26 moves upward, it will pull the piston rod 29 to drive the piston column 36 to move upward (left side). After the piston column 36 moves upward, it will suck air, thus driving the piston block 33 to slide outward. The piston block 33 pulls the valve plate 35 to slide into the piston chamber 30 through the pull rod 34, thus opening the discharge pipe 32 for discharging materials (at this time, the piston column 36 on the right side will move downward, and the piston block 33 on the right side will slide leftward under the pull, realizing staggered operation);

[0046] When the rotating plate 9 rotates rightward by a certain angle, vice versa according to the above principle, the right lifting plate 26 will move upward, and the left lifting plate 26 will move downward (it will move downward under negative pressure attraction);

[0047] Referring to the above principle, the valve plate 35 opens reciprocally, and the treatment agents in the storage cylinder 14 will be discharged, realizing reciprocating discharging. During the discharging process, the frame 4 is always moving, and the stirring rod 8 is also continuously stirring, so as to realize continuous stirring and mixing while also realizing intermittent discharging;

[0048] In addition, it should be noted that when the rotating plate 9 rotates to the central area, the second electromagnet 19 corresponds to the third electromagnet 27. The second electromagnet 19 and the third electromagnet 27 repel each other with the same polarities, thus causing the two lifting plates 26 to move downward to reset to the initial state, and the valve plate 35 closes the material discharging pipe.

[0049] Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 is that in this embodiment, laser distance sensors 38 are fixedly connected to both ends of the treatment tank 1. The laser distance sensors 38 and the first motor 5 are both electrically coupled to the control module 3. The control module 3 is fixedly connected to the outside of the treatment tank 1.

[0051] The above technical solution is explained as follows: when the rack 4 is moving, the moving distance of the rack 4 is detected by the laser ranging sensor 38. When the rack 4 approaches the edge of the treatment pool 1 or the distance reaches the set value, the control module 3 turns off the first motor 5 or controls the first motor 5 to reverse. The control module 3 can be an MCU controller or other types of controllers.

[0052] Embodiment 3

[0053] The present embodiment is different from the first embodiment in that, in the present embodiment, a resistance plate 31 is fixedly connected to the top of the lifting plate 26, a rotating rod 20 is rotatably connected to the outside of the storage tube 14, a torsion spring 22 is sleeved on the outside of the rotating rod 20, and both ends of the torsion spring 22 are respectively clamped with the buffer plate 21 and the outer wall of the storage tube 14, one end of the rotating rod 20 is fixedly connected to the buffer plate 21, and a limiting rod 23 is fixedly connected to the outside of the storage tube 14, the limiting rod 23 is used to block the buffer plate 21, and under the torsion force of the torsion spring 22, the buffer plate 21 will block the blocking rod, so arranged, when the lifting plate 26 moves upward under the cooperation of the first electromagnet 17 and the third electromagnet 27, it will resist the rotating plate 9 through the resistance plate 31, and the rotating plate 9 will rotate and squeeze the torsion spring 22 through the rotating rod 20, thereby playing a buffering role for the lifting plate 26.

[0054] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
