Description

Technical Field

[0001] This invention relates to the field of tailings wastewater treatment technology, specifically a multi-stage tailings wastewater treatment system. Background Technology

[0002] Tailings wastewater is industrial wastewater generated during mineral resource development, primarily originating from ore crushing, grinding, and beneficiation processes, as well as overflow from tailings ponds and rainfall runoff. It is characterized by large volume, high suspended solids content, complex composition, and large pH fluctuations. Direct discharge without effective treatment will cause serious pollution to the surrounding water environment, soil, and ecosystem. Therefore, tailings wastewater treatment is a crucial link in the sustainable development of the mining industry and a significant challenge for water resource protection and recycling.

[0003] In the multi-stage treatment of tailings wastewater, a crucial step is removing larger floating objects and soil impurities. This is achieved by adding an appropriate amount of flocculant to the sedimentation tank through a dedicated feed pipe. This flocculant possesses special chemical properties that promote the binding of floating objects and soil impurities in the wastewater, causing them to settle quickly. The treated wastewater is then discharged from the overflow outlet to the next stage of treatment. However, because the flocculant is added vertically to the sedimentation tank directly through the feed pipe, the contact area between the flocculant and the wastewater is relatively small. This reduces the efficiency of the flocculant binding with the floating objects and soil impurities, thus affecting the overall treatment efficiency. Summary of the Invention

The two ends of the elastic elements are fixedly connected to the side of the movable frame and the inner wall of one side of the groove.

[0009] Preferably, a connecting shaft is fixedly installed on the outer wall of the dosing tube, and one end of the connecting shaft is rotatably connected to the inner wall of the movable frame through a bearing.

[0010] Preferably, an adjusting rod is fixedly installed at one end of the connecting frame, and two protrusions are fixedly installed on the inner wall of the fixed housing. The outer wall of the adjusting rod is slidably connected to the inner wall of the fixed housing and the outer wall of the protrusions.

[0011] Preferably, a T-shaped groove is provided on the side of the connecting frame, a T-shaped block is slidably installed on the inner wall of the T-shaped groove, the side of the T-shaped block is fixedly connected to the side of the moving block, an adjustment groove is provided on the side of the moving block, an arc groove is provided on the side of the connecting frame, and the outer wall of the adjustment shaft is slidably connected to the inner wall of the arc groove and the inner wall of the adjustment groove.

[0012] Preferably, a T-shaped groove is provided on the side of the connecting frame, a T-shaped block is slidably installed on the inner wall of the T-shaped groove, the side of the T-shaped block is fixedly connected to the side of the moving plate, an inclined groove is provided through the side of the moving plate, an adjusting column is fixedly installed on the side of the moving block, and the outer wall of the adjusting column is slidably connected to the inner wall of the inclined groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention involves adding flocculant through a dosing pipe while simultaneously activating a motor to rotate a shaft, a fixed housing, and a protrusion. The rotating protrusion contacts an adjusting rod, which moves under the support of the protrusion. This movement of the adjusting rod drives the connecting frame and a moving frame, which in turn presses against an elastic element and moves the dosing pipe. When the protrusion moves away from the adjusting rod, the elastic force of the elastic element pushes the moving frame and dosing pipe back to their initial positions. As the fixed housing and protrusion continue to rotate, the dosing pipe reciprocates, causing the flocculant in the dosing pipe to reciprocate and be added to the wastewater in the sedimentation tank. This increases the contact area between the flocculant and the wastewater, allowing the flocculant to quickly combine with and settle floating matter and soil impurities in the wastewater, thereby improving the treatment efficiency of floating matter and soil in the wastewater. When the connecting frame and dosing pipe reciprocate, they drive the connecting columns on both sides to reciprocate in the corrugated groove, and drive the connecting strip, fixed column and moving plate to reciprocate up and down. The inclined groove on the moving plate drives the adjusting column and moving block to reciprocate horizontally. The adjusting groove on the moving block drives the adjusting shaft to reciprocate in an arc. The adjusting shaft drives the dosing pipe to reciprocate in an arc, increasing the contact area between the flocculant discharged from the dosing pipe and the wastewater. The flocculant can combine and precipitate with floating matter and soil impurities in the wastewater more quickly, further improving the treatment efficiency of floating matter and soil in the wastewater.

The upper end of the rotating shaft 106 rotates through the fixed frame 104 via a bearing and is fixedly connected to the output end of the motor 105. A stirring frame 107 is fixedly installed on the outer wall of the rotating shaft 106, and multiple scrapers 108 are fixedly installed on the lower outer wall of the stirring frame 107. The sides of the scrapers 108 are slidably connected to the lower inner wall of the sedimentation tank 1.

[0021] In this embodiment: the motor 105 drives the rotating shaft 106 and the stirring frame 107 to rotate. The stirring frame 107 slowly stirs the wastewater inside the sedimentation tank 1. The scraper 108 on the stirring frame 107 scrapes the sediment inside the sedimentation tank 1, causing the sediment to slide to the bottom of the sedimentation tank 1.

[0022] Specifically, such as Figures 1-8 As shown, a fixing plate 112 is fixedly installed on the outer wall of the sedimentation tank 1, and a pressure tank 114 is fixedly installed on the top surface of the fixing plate 112. One end of the pressure tank 114 is connected to the fixing sleeve 111 through a connecting pipe 113.

[0023] In this embodiment: one end of the pressurized tank 114 is connected to the sewage pipe, and sewage is added to the sedimentation tank 1 from the fixed sleeve 111 through the pressurized tank 114 and the connecting pipe 113.

[0024] The moving mechanism 2 is located above the sedimentation tank 1. The moving mechanism 2 includes a fixed shell 208 fixedly installed on the outer wall of the rotating shaft 106, a groove 201 through which the fixing strip 110 passes, a moving frame 203 slidably installed on the inner wall of the groove 201, and a connecting frame 206 fixedly installed on the top surface of the moving frame 203. Specifically, such as Figures 1-8 As shown, four limiting rods 202 are slidably installed through the side of the movable frame 203. The two ends of the limiting rods 202 are fixedly connected to the inner walls of the two ends of the groove 201. Elastic elements 205 are slidably installed on the outer wall of the limiting rods 202. The two ends of the elastic elements 205 are fixedly connected to the side of the movable frame 203 and the inner wall of one side of the groove 201.

[0025] In this embodiment: the limiting rod 202 is used to limit the movement of the moving frame 203, so that the movement of the moving frame 203 is more stable and less prone to deviation. The elastic element 205 applies elastic force to the moving frame 203.

[0026] Specifically, such as Figures 1-8 As shown, a connecting shaft 204 is fixedly installed on the outer wall of the dosing tube 109, and one end of the connecting shaft 204 is rotatably connected to the inner wall of the movable frame 203 through a bearing.

[0027] In this embodiment: flocculant is added to the sedimentation tank 1 through the dosing pipe 109. One end of the connecting shaft 204 is rotatably connected to the inner wall of the moving frame 203 through a bearing, so that the dosing pipe 109 can rotate.

[0028] Specifically, such as Figures 1-8 As shown, an adjusting rod 207 is fixedly installed at one end of the connecting frame 206, and two protrusions 209 are fixedly installed on the inner wall of the fixed shell 208. The outer wall of the adjusting rod 207 is slidably connected to the inner wall of the fixed shell 208 and the outer wall of the protrusions 209.

[0029] In this embodiment: With the fixed shell 208 and the protrusion 209 provided, when the rotating shaft 106 drives the fixed shell 208 and the protrusion 209 to rotate, the adjusting rod 207, the connecting frame 206, the moving frame 203 and the dosing tube 109 reciprocate under the joint action of the protrusion 209 and the elastic element 205.

[0030] The swing mechanism 3 is located above the sedimentation tank 1. The swing mechanism 3 includes an adjusting shaft 301 fixedly installed on the outer wall of the dosing pipe 109, and a moving block 305 and a moving plate 310 are provided on both sides of the connecting frame 206.

[0031] Specifically, such as Figures 1-8 As shown, a T-shaped groove 303 is provided on the side of the connecting frame 206, and a T-shaped block 304 is slidably installed on the inner wall of the T-shaped groove 303. The side of the T-shaped block 304 is fixedly connected to the side of the moving block 305. An adjustment groove 306 is provided on the side of the moving block 305, and an arc groove 302 is provided on the side of the connecting frame 206. The outer wall of the adjusting shaft 301 is slidably connected to the inner wall of the arc groove 302 and the inner wall of the adjustment groove 306.

[0032] In this embodiment: the T-shaped groove 303 is used to limit the T-shaped block 304, so that the T-shaped block 304 and the moving block 305 move more stably. When the moving block 305 moves back and forth, the adjustment groove 306 on the moving block 305 drives the adjustment shaft 301 to rotate in an arc.

[0033] Specifically, such as Figures 1-8 As shown, a T-shaped groove 308 is provided on the side of the connecting frame 206, and a T-shaped block 309 is slidably installed on the inner wall of the T-shaped groove 308. The side of the T-shaped block 309 is fixedly connected to the side of the moving plate 310. A sloping groove 311 is provided through the side of the moving plate 310. An adjusting column 307 is fixedly installed on the side of the moving block 305, and the outer wall of the adjusting column 307 is slidably connected to the inner wall of the sloping groove 311.

[0034] In this embodiment: the T-shaped groove 308 is used to limit the T-shaped block 309, so that the T-shaped block 309 and the moving plate 310 move more stably. When the moving plate 310 moves, the inclined groove 311 on the moving plate 310 drives the adjusting column 307 to move.

[0035] Specifically, such as Figures 1-8 As shown, a fixed post 312 is fixedly installed on the bottom surface of the movable plate 310, a connecting strip 313 is fixedly installed on the outer wall of the fixed post 312, and a connecting post 314 is fixedly installed on the side of the connecting strip 313.

[0036] In this embodiment: the connecting column 314 can drive the connecting strip 313 and the fixed column 312 to move, and the fixed column 312 drives the moving plate 310 to move.

[0037] Specifically, such as Figures 1-8 As shown, a corrugated groove 315 is provided on the side of the fixing strip 110, and the inner wall of the corrugated groove 315 is slidably connected to the outer wall of the connecting column 314.

[0038] In this embodiment: when the connecting post 314 moves in the corrugated groove 315, the connecting post 314 drives the connecting strip 313 to move up and down reciprocally.

[0039] The specific solution is as follows: One end of the pressure tank 114 is connected to the sewage pipe. Sewage is added to the sedimentation tank 1 through the pressure tank 114 and connecting pipe 113 from the fixed sleeve 111. The pipe is connected to the dosing pipe 109, and flocculant is added from the pipe. The flocculant is added to the sedimentation tank 1 through the dosing pipe 109. The motor 105 is turned on, causing the rotating shaft 106, the fixed shell 208, and the protrusion 209 to rotate. The protrusion 209 rotates and contacts the adjusting rod 207. The adjusting rod 207 moves under the support of the protrusion 209. 207 drives the connecting frame 206 and the moving frame 203 to move. The moving frame 203 presses against the elastic element 205 and drives the dosing pipe 109 to move. When the protrusion 209 moves away from the adjusting rod 207, the elastic force of the elastic element 205 pushes the moving frame 203 and the dosing pipe 109 back to their initial positions. As the fixed shell 208 and the protrusion 209 continue to rotate, the dosing pipe 109 reciprocates, and the flocculant in the dosing pipe 109 reciprocates and is added to the wastewater in the sedimentation tank 1. In the process of reciprocating movement of the connecting frame 206 and the dosing pipe 109, the connecting columns 314 on both sides reciprocate in the corrugated groove 315, which in turn drives the connecting strip 313, the fixed column 312, and the moving plate 310 to move up and down. The inclined groove 311 on the moving plate 310 drives the adjusting column 307 and the moving block 305 to move horizontally. The adjusting groove 306 on the moving block 305 drives the adjusting shaft 301 to rotate in an arc. The adjusting shaft 301 drives the dosing pipe 109 to rotate in an arc, increasing the amount of chemicals discharged from the dosing pipe 109. The contact area between the flocculant and the wastewater is increased. The rotating shaft 106 drives the stirring frame 107 to rotate. The stirring frame 107 slowly stirs the wastewater and flocculant inside the sedimentation tank 1. The flocculant can combine with the floating matter and mud impurities in the wastewater more quickly and settle. The scraper 108 on the stirring frame 107 scrapes the sediment inside the sedimentation tank 1, causing the sediment to slide to the bottom of the sedimentation tank 1. The treated wastewater flows from the overflow tank 102 and the overflow port 103 to the next stage for neutralization, adjustment, disinfection and discharge or reuse.
