[0031] Reference below Figures 1 to 4 The invention describes a mining wastewater sedimentation tank according to an embodiment of the utility model.

[0032] refer to Figures 1 to 4 As shown, the mining wastewater sedimentation tank according to an embodiment of the utility model includes a tank body 100 and a cleaning assembly 200.

[0033] The tank body 100 may be roughly cylindrical, and a water outlet weir 101 may be provided at the top of the tank body 100. The water outlet weir 101 may be annular, and the water outlet weir 101 extends along the circumference of the tank body 100. The water outlet weir 101 is a trough structure that opens upward, and a side of the water outlet weir 101 away from the center line of the tank body 100 may be provided with a plurality of water outlet grooves 104 or water outlet holes arranged along the circumference to achieve uniform drainage. The water outlet weir 101 is a common component of a sedimentation tank, and its structure and working principle are not described in detail here.

[0034] The cleaning assembly 200 includes a mounting frame 201, a cleaning mechanism 202 and two baffles 203. The mounting frame 201 is arranged on the pool body 100 and can be moved and adjusted along the circumference of the water outlet weir 101, and can be moved to different positions on the circumference of the water outlet weir 101. The cleaning mechanism 202 is arranged on the mounting frame 201 to clean the inside of the water outlet weir 101. The two baffles 203 are arranged on the mounting frame 201 and are respectively located on both sides of the cleaning mechanism 202 along the circumference of the water outlet weir 101, that is, the two baffles 203 are arranged along the water outlet weir 101. 01 is arranged circumferentially, and the cleaning mechanism 202 is located between two partitions 203. The plate surface of the partition 203 can be vertically arranged, and the plate surface of the partition 203 can be perpendicular to the circumferential direction of the water outlet weir 101. When the partition 203 is inserted into the water outlet weir 101, the two sides of the partition 203 can be attached to the two inner side walls of the water outlet weir 101 or very close to the two inner side walls of the water outlet weir 101, and the bottom end of the partition 203 can be attached to the bottom surface of the inside of the water outlet weir 101, thereby dividing the inside of the water outlet weir 101 in the circumferential direction.

[0035] In this embodiment, when the water outlet weir 101 needs to be cleaned, the mounting frame 201 is moved along the circumference of the water outlet weir 101 to the area of ​​the water outlet weir 101 that needs to be cleaned, and then two partitions 203 are inserted into the water outlet weir 101. The partitions 203 can separate the water outlet weir 101 in the circumferential direction, so that the area of ​​the water outlet weir 101 that needs to be cleaned is separated from other areas. Then, the cleaning mechanism 202 between the two partitions 203 can clean the area of ​​the water outlet weir 101 that needs to be cleaned. Due to the presence of the partitions 203, the cleaned materials will not flow to the rest of the water outlet weir 101, and will not be discharged to the outside of the sedimentation tank with the water to affect the water quality.

[0036] It should be noted that since the mounting frame 201 can be moved and adjusted along the circumference of the water outlet weir 101, various positions on the circumference of the water outlet weir 101 can be cleaned. Moreover, after cleaning one area, the mounting frame 201 can be moved to clean other areas, which makes the operation more convenient and the cleaning effect better.

[0037] In some embodiments of the present invention, Figure 2As shown, the cleaning component 200 also includes a lifting frame 204, which can be lifted and lowered on the mounting frame 201, and the cleaning mechanism 202 and the partition 203 are both arranged on the lifting frame 204. The lifting frame 204 can be lifted and lowered to a first position and a second position. When the lifting frame 204 is in the first position, the cleaning mechanism 202 and the partition 203 extend into the water outlet weir 101. When the lifting frame 204 is in the second position, the cleaning mechanism 202 and the partition 203 are located above the water outlet weir 101.

[0038] For example, the lifting frame 204 can be slidably installed on the mounting frame 201 vertically, and a lifting cylinder 216 can be vertically provided between the mounting frame 201 and the lifting frame 204. The lifting and lowering of the lifting frame 204 can be controlled by the extension and retraction of the lifting cylinder 216. In addition, a winch can also be set on the mounting frame 201. The winch is provided with a traction rope, and the traction rope is connected to the lifting frame 204. The winch controls the winding and unfolding of the traction rope to drive the lifting frame 204 to rise and fall. When the lifting frame 204 is in the first position, the cleaning mechanism 202 and the partition 203 extend into the water outlet weir 101. Either part of the cleaning mechanism 202 and part of the partition 203 extend into the water outlet weir 101, or all of the cleaning mechanism 202 and all of the partition 203 extend into the water outlet weir 101. In this state, the water outlet weir 101 can be cleaned. After the cleaning is completed, the lifting frame 204 can be raised to the second position. When the lifting frame 204 is in the second position, the cleaning mechanism 202 and the partition 203 are located above the water outlet weir 101, thereby preventing the cleaning mechanism 202 and the partition 203 from being damaged by being immersed in water for a long time. In addition, it is also more convenient for the mounting frame 201 to move and adjust, thereby preventing the cleaning mechanism 202 and the partition 203 from interfering with the movement of the mounting frame 201.

[0039] In some embodiments of the present invention, Figures 2 to 4 As shown, the cleaning assembly 200 also includes two sealing plates 205, which are disposed on the lifting frame 204 and arranged radially along the water outlet weir 101. When the lifting frame 204 is in the first position, the bottom ends of the two sealing plates 205 are located outside the two sides of the water outlet weir 101 in the radial direction. When the lifting frame 204 is in the second position, the two sealing plates 205 are located above the water outlet weir 101. When the water outlet weir 101 needs to be cleaned, the lifting frame 204 is lowered to the first position so that the bottom ends of the two sealing plates 205 are located on both sides of the water outlet weir 101 in the radial direction. In this way, during the cleaning process of the cleaning mechanism 202, the water in the pool body 100 can be reduced from entering the water outlet weir 101 between the two partitions 203, thereby making the cleaning of the cleaning mechanism 202 more convenient, and preventing the water mixed with cleaning materials in the water outlet weir 101 between the two partitions 203 from being directly discharged from the water outlet trough 104 or the water outlet hole on the side of the water outlet weir 101 away from the center line of the pool body 100, thereby further avoiding affecting the water quality.

[0040] In some embodiments of the present invention, Figures 2 to 4 As shown, the cleaning assembly 200 further includes an adjustment mechanism 206, which is arranged on the lifting frame 204 and connected to the two sealing plates 205 to control the radial movement of the two sealing plates 205 along the outlet weir 101. When the lifting frame 204 is in the first position, the sealing plates 205 can move to fit the outer wall of the outlet weir 101 or separate from the outer wall of the outlet weir 101. When the outlet weir 101 needs to be cleaned, the lifting frame 204 is lowered to the first position, and then the two sealing plates 205 are controlled by the adjustment mechanism 206 to move in a direction close to each other to fit the outer wall of the outlet weir 101, so that the water in the pool body 100 can be further prevented from entering the outlet weir 101 between the two partitions 203, and the water mixed with cleaning materials in the outlet weir 101 between the two partitions 203 can be further prevented from being directly discharged from the outlet trough 104 or the outlet hole on the side of the outlet weir 101 away from the center line of the pool body 100, which is more practical. After cleaning is completed, the two sealing plates 205 are controlled by the adjustment mechanism 206 to move away from each other until they are separated from the outer wall of the water outlet weir 101 . Then, the lifting frame 204 is raised to conveniently drive the two sealing plates 205 to rise above the water outlet weir 101 .

[0041] In some embodiments of the present invention, Figures 2 to 4 As shown, the sealing plate 205 is slidably mounted on the lifting frame 204 along the radial direction of the water outlet weir 101, and the adjusting mechanism 206 includes a screw rod 207 and a motor 209. The screw rod 207 is rotatably mounted on the lifting frame 204 and extends along the radial direction of the water outlet weir 101. The screw rod 207 has two sections of external threads 208 with opposite rotation directions, and is respectively threadedly connected with the two sealing plates 205 through the two sections of external threads 208. The motor 209 is arranged on the lifting frame 204 and connected to the screw rod 207 to control the rotation of the screw rod 207. When the motor 209 is started, the motor 209 can drive the screw rod 207 to rotate. Since the two sections of external threads 208 of the screw rod 207 rotate in opposite directions, the two sealing plates 205 can be driven to move synchronously in the direction of approaching or moving away from each other, and the structure is simpler and the operation is more convenient.

[0042] It should be noted that the adjustment mechanism 206 may also be other structures, for example, it may be two driving cylinders, which are respectively connected to the two sealing plates 205 and control the radial movement and adjustment of the two sealing plates 205 along the outlet weir 101.

[0043] In some embodiments of the present invention, Figure 2As shown, a drainage groove 102 is formed between the side wall of the pool body 100 and the water outlet weir 101, and the drainage groove 102 extends along the circumference of the pool body 100. The water outlet weir 101 is used to drain water into the drainage groove 102. The side wall of the pool body 100 is provided with a drainage hole 103 connected to the drainage groove 102. The water at the top of the pool body 100 first enters the water outlet weir 101, then enters the drainage groove 102 through the water outlet grooves 104 or water outlet holes at multiple positions on the circumference of the water outlet weir 101, and finally is discharged from the drainage holes 103 of the drainage groove 102, so that the drainage is more centralized and convenient.

[0044] In some embodiments of the present invention, Figure 2 As shown, the cleaning mechanism 202 includes a spray pipe 210, a water inlet pipe 212 and a first pump 213. The spray pipe 210 can extend into the water outlet weir 101. The spray pipe 210 is provided with a plurality of nozzles 211, and sprays water into the water outlet weir 101 through the nozzles 211. One end of the water inlet pipe 212 is connected to the spray pipe 210, and the other end can extend into the drain trough 102. The first pump 213 is connected to the water inlet pipe 212, so as to pump the water in the drain trough 102 into the spray pipe 210 through the water inlet pipe 212. For example, the spray pipe 210 may include two vertical spray pipes and one horizontal spray pipe, the two vertical spray pipes are arranged along the radial direction of the water outlet weir 101, and the two ends of the horizontal spray pipe are respectively connected to the bottom ends of the two vertical spray pipes.

[0045] When the water outlet weir 101 needs to be cleaned, the lifting frame 204 is lowered to the first position, the vertical spray pipe and the horizontal spray pipe are both located in the water outlet weir 101, the nozzle 211 of the vertical spray pipe faces the two inner walls of the water outlet weir 101, and the nozzle 211 of the horizontal spray pipe faces the bottom surface inside the water outlet weir 101, and the end of the water inlet pipe 212 away from the spray pipe 210 is extended into the drainage trough 102, and then the first pump 213 is started. The first pump 213 pumps part of the water in the drainage trough 102 into the vertical spray pipe and the horizontal spray pipe through the water inlet pipe 212, and finally sprays it out through the nozzle 211. The high-pressure water flow formed by the spraying can clean the water outlet weir 101. The structure is simple, the operation is convenient, the cleaning effect is good, and the water used is the relatively clean water in the drainage trough 102, so the cleaning effect is better.

[0046] It should be noted that the cleaning mechanism 202 may also be other structures, such as a brush or a roller brush.

[0047] In some embodiments of the present invention, Figure 2As shown, the cleaning mechanism 202 also includes a pumping pipe 214 and a second pump 215. One end of the pumping pipe 214 can extend into the outlet weir 101, and the other end can extend into the pool body 100. The second pump 215 is connected to the pumping pipe 214 to pump the water mixed with cleaning materials in the outlet weir 101 into the pool body 100 through the pumping pipe 214. Specifically, the suction pipe 214 and the second pump 215 can be arranged on the lifting frame 204, and one end of the suction pipe 214 can be provided with a trumpet-shaped suction hopper 217. When the lifting frame 204 descends to the first position, the end of the suction pipe 214 close to the suction hopper 217 can be close to the bottom surface inside the outlet weir 101, and the other end of the suction pipe 214 can extend into the pool body 100. Start the second pump 215, and the second pump 215 can pump the water mixed with cleaning materials between the two partitions 203 of the outlet weir 101 into the pool body 100, thereby completing the cleaning of the outlet weir 101. After the cleaning is completed, the lifting frame 204 can be raised to the second position, so that the two ends of the suction pipe 214 are respectively located above the outlet weir 101 and above the pool body 100.

[0048] In this embodiment, the cleaned material is directly pumped into the tank body 100 through the second pump 215, thereby further preventing the cleaned material from flowing to the rest of the water outlet weir 101 and affecting the water quality. In addition, after the water mixed with the cleaned material enters the tank body 100, part of it can be precipitated with the sludge, and part of it can float on the top surface of the tank body 100 and be processed by the scum processing mechanism, without having to be discharged to the outside for processing, which is more convenient and has a better processing effect.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the mining wastewater sedimentation tank also includes a scraper assembly 300, which includes a column 301, a scraper bridge 302 and a scraper plate 303. The column 301 is arranged at the middle of the bottom end of the tank body 100, the scraper bridge 302 is arranged at the top of the column 301 and can rotate around the axis of the column 301, and the scraper plate 303 is connected to the scraper bridge 302 and adheres to the inner surface of the tank body 100.

[0050] For example, the axis line of the column 301 can coincide with or nearly coincide with the center line of the pool body 100, and a mounting shaft can be vertically provided on the column 301, and the scraper bridge 302 is rotatably installed on the mounting shaft. The column 301 is also provided with a driving mechanism, and the driving mechanism controls the rotation of the scraper bridge 302. The scraper bridge 302 can be provided with a plurality of connecting rods 304 extending to the bottom end of the pool body 100, and the scraper plates 303 can be connected to the connecting rods 304, and the scraper plates 303 can be attached to the bottom surface of the pool body 100.

[0051] By starting the driving mechanism, the scraper bridge 302 can be driven to rotate, thereby driving the scraper plate 303 to rotate around the axis of the column 301. The scraper plate 303 can scrape off the sludge at the bottom of the pool body 100 and discharge it from the sludge discharge hole, thereby preventing the sludge from accumulating in the pool body 100.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the mounting frame 201 is connected to the scraper bridge 302. In this embodiment, the mounting frame 201 is arranged on the scraper bridge 302, so that the scraper bridge 302 can not only drive the scraper plate 303 to scrape the inner surface of the sedimentation tank, but also drive the mounting frame 201 to move along the circumferential direction of the outlet weir 101, without the need to set other structures for driving the mounting frame 201 to move, and the mounting frame 201 has dual functions in one body, a simpler structure, and more convenient operation.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
