Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a cleaning device suitable for a sedimentation tank in sewage treatment. Background Art

[0002] In the sewage treatment process, sedimentation tanks play a vital role. They can settle the solid particles in the sewage, thereby separating the water from the solid matter. Over time, a large amount of sediment will accumulate at the bottom of the sedimentation tank, and a cleaning device is needed to clean the sludge at the bottom of the sedimentation tank.

[0003] After scraping the sludge, the traditional sedimentation tank cleaning device needs to store the sludge on the sludge platform and then clean it manually, which increases the manpower and time cost. On the other hand, most of the existing scraping mechanisms can only scrape the sludge in one direction. After completing one scraping, a reset operation is required before the next scraping can be performed. This process is not only time-consuming, but also reduces the cleaning efficiency.

[0004] Technical issues solved

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a cleaning device suitable for a sedimentation tank in sewage treatment.

[0008] As mentioned above, a motor cavity is opened inside the driving bin, a transport motor is fixedly connected inside the motor cavity, a closed cavity is opened on the driving bin, a pulley one is fixedly connected to the output end of the transport motor, the pulley one is located inside the closed cavity, a pulley two is rotatably connected inside the closed cavity, a belt is connected for transmission between the pulley one and the pulley two, and a transport roller is fixedly connected to the pulley two.

[0009] As described above, a transport groove is formed between the first scraping plate and the second scraping plate. The transport roller is arranged inside the transport groove, and a spiral disk is fixedly connected to the surface of the transport roller.

[0010] As described above, an extraction cavity is formed inside the extraction bin. A suction pipe is arranged inside one side of the displacement frame close to the extraction bin, and the bottom of the suction pipe is located inside the extraction cavity.

[0011] As described above, a displacement threaded rod is threadedly connected to the top of the displacement frame. A guiding hole is formed in the displacement frame, and a guiding rod is slidably connected to the inner surface of the guiding hole. Mounting frames are fixedly connected to both sides of the guiding rod.

[0012] As described above, a displacement motor is fixedly connected to one of the mounting frames, and the displacement threaded rod is installed at the output end of the displacement motor.

[0013] As described above, a guide groove frame is fixedly connected to the mounting frame. A diversion groove is fixedly connected to the top of the guide groove frame, and long and short diversion baffles are fixedly connected to the top of the diversion groove.

[0014] The technical solution provided by the present utility model has the following beneficial effects compared with the prior art:

[0015] First, through the spiral disk provided in the present utility model, the conveying motor drives the first pulley to rotate, drives the second pulley to rotate through the belt, and the conveying roller rotates to drive the spiral disk to work, transporting the silt scraped by the two scraping plates to the extraction cavity through the rotation of the spiral disk, and then the silt in the extraction cavity is extracted by the extraction pump to the suction pipe and discharged through the discharge port, so that the silt can be directly transported outside the sedimentation tank without the need for intermediate storage on the silt platform, greatly saving the subsequent manual cleaning time.

[0016] Second, through the first scraping plate and the second scraping plate provided in the present utility model, when the displacement motor drives the displacement frame to move to the right, the first scraping plate starts to scrape the silt. At this time, the rotating plate on one side of the first scraping plate rotates into the transport groove, and the rotating plate on one side of the second scraping plate does not rotate due to the limiting plate, ensuring that when the first scraping plate works, the silt will not flow to the side of the second scraping plate due to excessive silt.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-4As shown in the figure, the utility model provides a technical solution: a cleaning device applicable to sedimentation tanks in sewage treatment includes a displacement frame 1. A scraping mechanism 2 is arranged at the bottom of the displacement frame 1. One side of the scraping mechanism 2 is fixedly connected with a driving chamber 3, and the other side of the scraping mechanism 2 is fixedly connected with a pumping chamber 4. A baffle 14 is fixedly connected between the driving chamber 3 and the pumping chamber 4. A first scraping plate 15 is fixedly connected between the driving chamber 3 and the pumping chamber 4. A second scraping plate 16 is fixedly connected between the driving chamber 3 and the pumping chamber 4. The first scraping plate 15 and the second scraping plate 16 are oppositely arranged on the left and right sides of the baffle 14. Rotating plates 21 are hinged on both the left and right sides of the baffle 14. A limiting plate 22 is fixedly connected to the bottom of the rotating plate 21. A pumping pump 19 is fixedly connected to the top of the displacement frame 1. A discharge port 20 is provided on the pumping pump 19.

[0025] As Figures 1-4 shown, a motor chamber 5 is provided inside the driving chamber 3. A conveying motor 6 is fixedly connected inside the motor chamber 5. A sealed chamber 7 is provided on the driving chamber 3. The output end of the conveying motor 6 is fixedly connected with a first pulley 8. The first pulley 8 is located inside the sealed chamber 7. A second pulley 9 is rotatably connected inside the sealed chamber 7. A belt 10 is drivingly connected between the first pulley 8 and the second pulley 9. A conveying roller 11 is fixedly connected to the second pulley 9. A conveying groove 12 is provided between the first scraping plate 15 and the second scraping plate 16. The conveying roller 11 is arranged inside the conveying groove 12. A spiral plate 13 is fixedly connected to the surface of the conveying roller 11. A pumping chamber 17 is provided inside the pumping chamber 4. A suction pipe 18 is arranged inside one side of the displacement frame 1 close to the pumping chamber 4. The bottom of the suction pipe 18 is located inside the pumping chamber 17. The conveying motor 6 drives the first pulley 8 to rotate, drives the second pulley 9 to rotate through the belt 10, and the conveying roller 11 rotates to drive the spiral plate 13 to work, transporting the sludge scraped by the two scraping plates to the pumping chamber 17 through the rotation of the spiral plate 13, and then pumping the sludge in the pumping chamber 17 to the suction pipe 18 through the pumping pump 19 and discharging it through the discharge port 20. Thus, the sludge can be directly transported outside the sedimentation tank without the need for intermediate storage on the sludge platform, greatly saving the subsequent manual cleaning time.

[0026] As Figure 1 、 Figure 4As shown in the figure, a displacement screw rod 23 is threadedly connected to the top of the displacement frame 1. A guiding hole 29 is formed in the displacement frame 1. A guiding rod 30 is slidably connected to the inner surface of the guiding hole 29. Mounting frames 25 are fixedly connected to both sides of the guiding rod 30. A displacement motor 24 is fixedly connected to one of the mounting frames 25. The displacement screw rod 23 is installed at the output end of the displacement motor 24. A guiding groove frame 26 is fixedly connected to the mounting frame 25. A guiding groove 27 is fixedly connected to the top of the guiding groove frame 26. Long and short guiding baffles 28 are fixedly connected to the top of the guiding groove 27. The cleaning device is installed on the top of the sedimentation tank through the mounting frame 25. After the displacement motor 24 is started, driven by the guiding of the displacement screw rod 23 and the guiding rod 30, the displacement frame 1 moves inside the sedimentation tank. When the displacement motor 24 drives the displacement frame 1 to move to the right, the first scraping plate 15 starts to scrape the sludge. At this time, the rotating plate 21 on one side of the first scraping plate 15 rotates into the conveying tank 12. The rotating plate 21 on one side of the second scraping plate 16 does not rotate due to the limiting plate 22, ensuring that when the first scraping plate 15 is working, the sludge will not flow to the side of the second scraping plate 16 due to excessive sludge. When cleaning the sedimentation tank, it is usually necessary to scrape the sludge at the bottom of the sedimentation tank multiple times. When the first scraping plate 15 resets, the second scraping plate 16 starts to work. After the sludge is extracted, the sludge is discharged into the guiding groove 27 through the discharge port 20. The short guiding baffle 28 is close to the discharge port 20, and the long guiding baffle 28 can block the sludge with too fast discharge speed from the discharge port 20.

[0027] Working principle: The conveying motor 6 drives the first pulley 8 to rotate, drives the second pulley 9 to rotate through the belt 10, and the conveying roller 11 rotates to drive the spiral disk 13 to work, transporting the sludge scraped by the two scraping plates to the extraction chamber 17 through the rotation of the spiral disk 13, and then extracting the sludge in the extraction chamber 17 to the suction pipe 18 through the extraction pump 19 and discharging it through the discharge port 20. When the displacement motor 24 drives the displacement frame 1 to move to the right, the first scraping plate 15 starts to scrape the sludge. At this time, the rotating plate 21 on one side of the first scraping plate 15 rotates into the conveying tank 12. The rotating plate 21 on one side of the second scraping plate 16 does not rotate due to the limiting plate 22, ensuring that when the first scraping plate 15 is working, the sludge will not flow to the side of the second scraping plate 16 due to excessive sludge. When cleaning the sedimentation tank, it is usually necessary to scrape the sludge at the bottom of the sedimentation tank multiple times. When the first scraping plate 15 resets, the second scraping plate 16 starts to work.
