If the sewage is directly discharged without treatment, it will cause serious damage to the environment, affect the ecological balance, and even endanger human health. Therefore, the research and application of mine sewage treatment technology are particularly important. The mine sewage treatment tank as an important physical and chemical treatment facility plays a key role in the treatment of mine wastewater.

[0003] Nowadays, the design and construction of the mine sewage treatment tank are mainly based on the comprehensive use of various sewage treatment technologies such as sedimentation, oxidation-reduction, adsorption and biodegradation. The traditional sedimentation tank increases the sewage residence time to promote the natural sedimentation of particulate matter, realizes solid-liquid separation, and the improved coagulation sedimentation tank accelerates the sedimentation process by adding flocculants to improve the treatment efficiency. However, no matter which type of sedimentation tank is used, a large amount of sludge is usually deposited at the inner bottom of the sedimentation tank when treating sewage, and if the sludge is not treated in time when it accumulates at the bottom of the sedimentation tank, it will affect the sedimentation of the sedimentation tank.

[0033] Referring to Figure 6 and Figure 7 As shown, the squeezing mechanism comprises an electric push rod 20 and a pressing plate 21; the twelve electric push rods 20 are symmetrically connected to the front and rear sides of the rotating block 6; the pressing plate 21 is connected to the telescopic rod of the electric push rod 20, so that the electric push rod 20 can drive the pressing plate 21 to move and squeeze the cloth bag 8.

[0034] When in use, sewage is continuously discharged into the sedimentation tank 2 through the water inlet pipe 3, and a certain amount of flocculating agent is regularly added into the sedimentation tank 2 to make the sewage flocculate and precipitate in the sedimentation tank 2, and the sludge in the sewage is deposited on the inner bottom of the sedimentation tank 2 through sedimentation, and the clear water discharged through sedimentation of the sewage gradually overflows upwards into the overflow frame and is discharged through the drain pipe, and then the mud scraping plate 11 is slowly rotated by the servo motor 10 to drive the mud scraping plate 11 to scrape the sludge deposited on the inner bottom of the sedimentation tank 2 towards the mud outlet 4 to discharge the sludge from the mud outlet 4, and then the rotating block 6 is rotated clockwise by the driving element 7 to drive, and when the mud outlet 4 is aligned with the through slot 61 on the rotating block 6, the rotating block 6 does not block the bottom end of the mud outlet 4 at this time, and the sludge can be discharged from the mud outlet 4 and pass through the through slot 61 on the rotating block 6 to be loaded into the cloth bag 8, and when the mud outlet 4 is no longer aligned with the through slot 61 on the rotating block 6, the rotating block 6 will block the bottom end of the mud outlet 4 again, and when the cloth bag 8 in the through slot 61 completes the bagging of the sludge, the two-way screw rod 16 is rotated by the speed reducer motor I 17 to drive, thereby driving the two moving plates 18 on the two-way screw rod 16 to move towards each other, and the two moving plates 18 will squeeze the two folding plates 19 on them to fold, so that the moving plates 18 and the folding plates 19 begin to drive the cloth bag 8 on them to seal, and after the sealed cloth bag 8 completes the bagging, the pressure plate 21 is moved towards each other by the electric push rod 20 to drive, so that the pressure plate 21 contacts and squeezes the cloth bag 8 to be bagged, thereby squeezing the sludge in the cloth bag 8, and then the sewage in the sludge is squeezed out, and the squeezed-out sewage flows out from the through slot 61 to the water collecting frame 12 to be collected, and then the sewage collected in the water collecting frame 12 is pumped into the backflow pipe 14 by the water pump 13 to make the sewage backflow to the water inlet pipe 3 to be re-precipitated, and after the sludge in the cloth bag 8 completes the squeezing and dewatering, when the cloth bag 8 is rotated with the rotating block 6 to align the orientation of the cloth bag 8 opening with the mud plate 9, the two-way screw rod 16 is reversed by the speed reducer motor I 17 to drive to reset, thereby driving the two moving plates 18 on the two-way screw rod 16 to move away from each other to reset, and the two moving plates 18 will pull the two folding plates 19 on them to unfold, so that the moving plates 18 and the folding plates 19 begin to drive the cloth bag 8 on them to open, thereby making the dewatered sludge in the cloth bag 8 fall downwards onto the mud plate 9 and be discharged, and thus the sludge on the inner bottom of the sedimentation tank 2 is completed once dewatered and discharged, and then the rotating block 6 is continuously rotated by the driving element 7 to drive, so that the six cloth bags 8 on the rotating block 6 can in turn repeatedly dewater and discharge the sludge on the inner bottom of the sedimentation tank 2, and thus the sludge on the inner bottom of the sedimentation tank 2 can be automatically dewatered and discharged, which not only saves time and effort, but also has high efficiency.

[0035] Referring to Figure 7As shown, the vibration mechanism comprises a sliding column 22, a vibration motor 23 and a spring I 24; the sliding column 22 is slidingly connected to the middle of the rotating block 6 and connected with the cloth bag 8; the vibration motor 23 is connected to the sliding column 22 and used to drive the sliding column 22 and the cloth bag 8 to vibrate, so as to shake off the residual sludge in the cloth bag 8; and the spring I 24 is connected to the sliding column 22 and the rotating block 6 at both ends.

[0036] When the six cloth bags 8 on the rotating block 6 repeatedly dehydrate and discharge the sludge at the bottom of the sedimentation tank 2 in turn, the vibration motor 23 can be started to drive the sliding column 22 to vibrate in the rotating block 6, so that the spring I 24 is deformed and the sliding column 22 drives the cloth bag 8 to vibrate. In this way, the sludge in the cloth bag 8 which has completed dehydration can be dropped faster by the vibration of the cloth bag 8, so as to reduce the residual sludge in the cloth bag 8; finally, when the sludge in the sedimentation tank 2 has been completely dehydrated and discharged, the vibration motor 23 is turned off, so that the spring I 24 returns to its original state and drives the sliding column 22 to reset.

[0037] Referring to Figure 8 As shown, the filter plate 25 is connected to the inside lower side of the sedimentation tank 2 and used to block the sludge at the bottom of the sedimentation tank 2, while the sewage and the precipitated clean water can flow upwards through the filter plate 25, and the filter plate 25 is located above the water outlet of the water inlet pipe 3, so that the sludge in the sewage cannot be precipitated above the filter plate 25.

[0038] By arranging the filter plate 25, the filter plate 25 can block the sludge precipitated at the bottom of the sedimentation tank 2, so as to limit the sludge below the inside of the sedimentation tank 2, so that the sludge can be scraped to the sludge outlet 4 by the sludge scraping plate 11.

[0039] Referring to Figure 9 and Figure 10The buffer mechanism further includes a confluence plate 26, a support rod 27, a water blocking frame 28, a speed reducer motor II 29, a one-way screw rod 30, a movable plate 31 and a spring II 32. The confluence plate 26 is connected to the water inlet pipe 3 and is used to gather the sewage in the water inlet pipe 3. The support rod 27 is connected to the inside of the water inlet pipe 3. The water blocking frame 28 is rotatably connected to the support rod 27. When the sewage in the water inlet pipe 3 flows to the water blocking frame 28, the water blocking frame 28 can block the sewage in the water inlet pipe 3 and rotate, thereby increasing the resistance of the sewage in the water inlet pipe 3. The speed reducer motor II 29 is connected to the water inlet pipe 3. The one-way screw rod 30 is connected to the output shaft of the speed reducer motor II 29, so that the speed reducer motor II 29 can drive the one-way screw rod 30 to rotate. The movable plate 31 is slidably connected to the water inlet pipe 3 and is threadedly connected to the one-way screw rod 30, so that the one-way screw rod 30 can drive the movable plate 31 to move when the one-way screw rod 30 rotates. The spring II 32 has two ends respectively connected to the bottom end of the movable plate 31 and the top end of the support rod 27, so that the spring II 32 can be pressed down to contact the water blocking frame 28 when the movable plate 31 is pressed down, thereby increasing the resistance of the rotating water blocking frame 28 by the spring II 32, and further improving the buffering strength of the water blocking frame 28 to the sewage.

[0040] The confluence plate 26 can gather the sewage in the water inlet pipe 3 and make the gathered sewage impact the water blocking frame 28, thereby driving the water blocking frame 28 to rotate and blocking the gathered sewage, so as to increase the resistance of the sewage in the water inlet pipe 3, thereby slowing down the flow rate of the sewage in the water inlet pipe 3 and preventing the sewage from impacting the sludge accumulated in the sedimentation tank 2 when being discharged. The speed reducer motor II 29 drives the one-way screw rod 30 to rotate, so that the movable plate 31 moves downward to compress the spring II 32 and press the spring II 32 down to contact the water blocking frame 28, thereby increasing the resistance of the rotating water blocking frame 28 by the spring II 32 and further improving the buffering strength of the water blocking frame 28 to the sewage. When it is necessary to reduce the buffering strength of the water blocking frame 28 to the sewage, the speed reducer motor II 29 can drive the one-way screw rod 30 to reverse, so that the movable plate 31 moves upward to stretch the spring II 32 and gradually separate the spring II 32 from the water blocking frame 28, thereby reducing the resistance of the rotating water blocking frame 28 by the spring II 32 and further reducing the buffering strength of the water blocking frame 28 to the sewage.
