DETAILED DESCRIPTION

[0032] Example 1: Figure 1-Figure 2 As shown, a black and odorous water treatment device includes an inner filter cartridge 2, the upper end surface of the inner filter cartridge 2 is provided with a liquid inlet 1, the outer end surface of the inner filter cartridge 2 is sleeved with an outer filter cartridge 3, the lower end surface of the inner filter cartridge 2 is rotatably connected to a rotating cylinder 16, the interior of the rotating cylinder 16 is provided with a filter chamber 8, the filter chamber 8 is movably connected to a movable filter plate 9, a fine filter screen 11 is embedded in the middle of the inner wall of the rotating cylinder 16, a spoiler 17 is fixedly connected to the inner wall of the rotating cylinder 16, and a rotating aeration device 13 is fixedly connected to the lower end surface of the rotating cylinder 16. The rotating aeration device 13 A rotating dial plate 15 is fixedly connected to the side end face, a spiral feed pipe 5 is fixedly installed on the lower end face of the rotating aeration device 13, a collecting bin 10 and an aeration bin 18 are provided inside the outer filter cartridge 3, the collecting bin 10 is communicated with the filter cavity 8, the aeration bin 18 is fitted with the fine filter screen 11, a cleaning device 12 for cleaning the fine filter screen 11 is rotatably connected to the inside of the aeration bin 18, the outer end face of the aeration bin 18 is connected to the liquid outlet 7, and the outer end face of the outer filter cartridge 3 is provided with a driving mechanism 6 for driving the rotating dial plate 15 to rotate.

[0033] During use, sewage is put into the interior of the inner filter cartridge 2 through the liquid inlet 1, and is coarsely filtered when passing through the filter cavity 8. Some macromolecular impurities are filtered through the movable filter plate 9. After coarse filtration, the sewage flows into the interior of the rotating cylinder 16 through the movable filter plate 9. Since the rotating cylinder 16 is fixedly connected to the rotating aeration device 13, the rotating cylinder 16 can be driven to rotate by the rotating aeration device 13 by rotating the rotating dial 15, and the rotating dial 15 is connected to a driving mechanism 6 for driving its rotation. When the rotating cylinder 16 rotates, the spoiler 17 is driven to rotate, so that the liquid in the rotating cylinder 16 rotates. During the rotation, the liquid generates centrifugal motion for centrifugal filtration, and the sewage is centrifuged. A vortex is generated, and then the sewage flows into the aeration bin 18 through the filtration of the fine filter 11, and the sewage is finely filtered. The bottom of the aeration bin 18 carries biologically activated sludge. After fine filtration, the sewage is treated aerobically, anaerobicly, etc. in the aeration bin 18. The treated liquid flows out through the liquid outlet 7 for collection. In order to avoid clogging of the fine filter 11, a cleaning device 12 is rotatably connected to the inside of the aeration bin 18. The device has a compact structure, high processing capacity, and is easy to install and carry. At the same time, a spiral feed pipe 5 is installed on the lower end face of the rotating aeration device 13. The spiral feed pipe 5 is used to send out the sludge generated by centrifugal filtration in the rotating drum 16 to avoid accumulation inside the rotating drum 16 affecting the filtration effect.

[0034] Example 2: Figure 1-Figure 3 As shown, on the basis of Example 1, the movable filter plate 9 includes a counterweight device 19, a connecting rod 20, a rotating shaft 21, a central filter plate 22 and a flexible filter screen 26. The central filter plate 22 is located in the middle of the filter chamber 8, and the connecting rod 20 is rotatably connected to the side end surface of the central filter plate 22 through the rotating shaft 21. The counterweight device 19 is movably connected to the end of the connecting rod 20 away from the rotating shaft 21, and the flexible filter screen 26 fills the gap between the connecting rod 20 and the inner wall of the rotating cylinder 16.

[0035] like Figure 1-Figure 4 As shown, a rotating groove 23 is opened on the inner wall of the rotating cylinder 16 , the collecting bin 10 is connected with the filter chamber 8 through the rotating groove 23 , and the connecting rod 20 rotates through the rotating shaft 21 and is connected to the inside of the rotating groove 23 .

[0036] like Figure 1-Figure 4 As shown, the counterweight device 19 is fixedly connected to a movable rod 25 , a movable slot 24 is defined inside the connecting rod 20 , and one end of the movable rod 25 facing away from the counterweight device 19 is elastically connected to the inside of the movable slot 24 .

[0037] During use, the interior of the filter chamber 8 filters the sewage through the central filter plate 22 and the flexible filter screen 26, and the filtered impurities accumulate inside the flexible filter screen 26. When the movable filter plate 9 rotates with the rotating cylinder 16, the counterweight device 19 inside the connecting rod 20 causes the movable rod 25 to move away from the movable groove 24 under the action of centrifugal force, and the weight density of the counterweight device 19 is relatively high. A rotating shaft 21 is provided inside the rotating groove 23. When the counterweight device 19 moves in the direction away from the connecting rod 20, the lever principle can be used to drive the connecting rod 20 to rotate with the rotating shaft 21 inside the rotating groove 23 as the fulcrum, so that the central filter plate 22 forms a bulge relative to the flexible filter screen 26, so that the debris on the surface of the flexible filter screen 26 passes through the flexible filter screen 26 and slides into the interior of the collection bin 10 through the rotating groove 23 for collection.

[0038] like Figure 1-Figure 2 and Figure 5 As shown, the rotary aeration device 13 includes a funnel trough 27, a rotating aeration plate 28 and an aeration device body 30. The aeration device body 30 is rotatably connected to the upper end surface of the spiral feeding pipe 5, and the rotating aeration plate 28 is fixedly connected to the upper end surface of the aeration device body 30. The funnel trough 27 is opened through the interior of the rotating aeration plate 28 and the aeration device body 30.

[0039] like Figure 1-Figure 2 and Figure 5-Figure 7 As shown, an annular air gap 32 is provided inside the rotating aeration plate 28, the lower end face of the annular air gap 32 is connected to the annular air cavity 14, the annular air cavity 14 is connected to the air inlet pipe 4, and the upper end face of the annular air gap 32 is connected to multiple groups of air outlet pipes 31 in the tangential direction. The air outlet pipes 31 are provided inside the rotating aeration plate 28, and the air inlet pipe 4 is rotatably connected to the lower end face of the aeration device body 30, and the end of the air outlet pipe 31 facing away from the annular air gap 32 is connected to the aeration bin 18.

[0040] When in use, the aeration device body 30 and the rotating aeration plate 28 can be rotated by rotating the dial plate 15, thereby driving the liquid in the filter chamber 8 to be centrifugally filtered. Furthermore, an outlet pipe 31 is provided in the rotating aeration plate 28, and the outlet pipe 31 is connected to the annular air cavity 14 through the annular air gap 32, and the outlet pipe 31 is arranged at a tangent angle, and the gas is blown into the annular air gap 32 and the outlet pipe 31 through the inlet pipe 4, and the gas is finally discharged into the aeration bin 18 through the outlet pipe 31. When the gas is discharged through the outlet pipe 31 A rotational thrust will be formed on the rotating aeration plate 28, so that the rotating aeration device 13 can rotate autonomously under gas power without the need for long-term pushing. At the same time, the gas can adjust the oxygen content and other components as needed, so that the biological sludge and sewage in the aeration bin 18 are mixed more fully while providing air components for the aerobic reaction. Compared with traditional aeration devices, the air flow of the rotating aeration device 13 is in a rotating state during aeration, which makes the air flow more dispersed and can further promote the mixing of activated sludge and sewage, thereby improving the aeration treatment effect.

[0041] like Figure 1-Figure 2 and Figure 9 As shown, a limit block 38 is embedded at the connection between the annular air gap 32 and the air outlet pipe 31, and a one-way baffle 39 is fitted on the limit block 38. The end of the one-way baffle 39 facing away from the limit block 38 is rotatably connected to the inner wall of the annular air gap 32. A spring 37 is fixedly connected to the middle of the one-way baffle 39, and the end of the spring 37 facing away from the annular air gap 32 is elastically connected to the inner wall of the air outlet pipe 31.

[0042] During use, the one-way baffle 39 forms a one-way conduction for the air outlet pipe 31 to prevent the backflow of sewage or activated sludge inside the aeration bin 18. When air flows through the annular air gap 32, the air flow pushes the one-way baffle 39 to rotate and compresses the spring 37, so that a gap is generated between the one-way baffle 39 and the limit block 38 for air flow to pass through. Similarly, when no air flows through the annular air gap 32, the one-way baffle 39 is pressed against the limit block 38 under the action of the spring 37 to prevent the backflow of sewage or activated sludge.

[0043] like Figure 1-Figure 2 and Figure 9-10 As shown, the cleaning device 12 includes a cleaning brush 33, a rotating rod 34, a spiral blade 35 and a driving gear 36. The rotating rod 34 is rotatably connected to the inside of the aeration bin 18, the driving gear 36 is fixedly connected to the bottom of the rotating rod 34, the spiral blade 35 is fixedly connected to the side end surface of the rotating rod 34, and the cleaning brush 33 is fixedly connected to the upper side end surface of the rotating rod 34, and the cleaning brush 33 is in contact with the fine filter 11.

[0044] like Figure 1-Figure 2 、 Figure 5-Figure 7 and Figure 9-10 As shown, a tooth groove 29 is provided on the side end surface of the rotating aeration plate 28 to engage with the driving gear 36.

[0045] During use, the rotating aeration plate 28 is driven by the gas to rotate and centrifugally filter the sewage in the filter chamber 8. During the centrifugal filtration, the rotating aeration plate 28 can drive the driving gear 36 to rotate through the tooth groove 29. The driving gear 36 drives the rotating rod 34 to rotate. The rotation of the rotating rod 34 also drives the rotation of the cleaning brush 33 and the spiral blade 35. The rotation of the spiral blade 35 can make the sludge at the bottom of the aeration bin 18 float up, avoiding the accumulation of activated sludge affecting the filtration effect. At the same time, the fine filter screen 11 can also be cleaned by rotating the cleaning brush 33 to avoid clogging of the fine filter screen 11. The aeration plate 28 is driven to rotate, and the filtration effect is further improved during the aeration process.

[0046] like Figure 1-Figure 2 and Figure 11 As shown, the driving mechanism 6 includes an outer gear ring 41, a driving source 42 and a driving wheel 44. The driving source 42 drives a driving shaft 43. The driving wheel 44 is keyed to the driving shaft 43. The outer gear ring 41 is fixedly connected to the outer end surface of the rotating lever 15, and the driving wheel 44 is provided with a tooth groove that meshes with the outer gear ring 41.

[0047] Furthermore, a protective shell 40 is provided on the outer surface of the driving wheel 44 and the outer gear ring 41. The protective shell 40 is fixedly connected to the outer filter cartridge 3 to improve the safety of the device and prevent debris from falling into the gear gap and affecting the use of the device.

[0048] When in use, the driving source 42 drives the driving shaft 43 to drive the driving wheel 44 to rotate, and the driving wheel 44 engages with the outer gear ring 41 to drive the rotation of the rotating dial 15. The driving source 42 can be a rotating driving member such as a motor or an internal combustion engine as needed.

[0049] Working principle: sewage is put into the interior of the inner filter cartridge 2 through the liquid inlet 1, and is coarsely filtered when passing through the filter chamber 8. Some large molecular impurities are filtered through the movable filter plate 9. After coarse filtration, the sewage flows into the interior of the rotating cylinder 16 through the movable filter plate 9. Since the rotating cylinder 16 is fixedly connected to the rotating aeration device 13, the aeration device 13 can be rotated by rotating the rotating dial 15 to drive the rotating cylinder 16 to rotate, and the rotating dial 15 is connected to the driving mechanism 6. The driving shaft 43 is driven by the driving source 42 to drive the driving wheel 44 to rotate, and the driving wheel 44 is engaged with the outer gear ring 41 to drive the rotation of the rotating dial 15. The driving source 42 can select a rotating driving member such as a motor or an internal combustion engine as needed. The rotating cylinder 16 rotates and drives the spoiler 17 at the same time. The rotation causes the liquid in the rotating drum 16 to rotate. During the rotation, the liquid generates centrifugal motion for centrifugal filtration. The sewage generates a vortex with the centrifugal motion, and then flows into the aeration bin 18 through the filtration of the fine filter 11 to finely filter the sewage. The bottom of the aeration bin 18 carries biologically activated sludge. After fine filtration, the sewage is treated aerobically and anaerobically in the aeration bin 18. The treated liquid flows out through the liquid outlet 7 for collection. In order to avoid clogging of the fine filter 11, a cleaning device 12 is rotatably connected to the inside of the aeration bin 18. The device has a compact structure, high processing capacity, and is easy to install and carry. At the same time, a spiral feed pipe 5 is installed on the lower end face of the rotating aeration device 13. The spiral feed pipe 5 is used to transfer the sewage generated by centrifugal filtration in the rotating drum 16 The mud is sent out to avoid accumulation inside the rotating cylinder 16 and affecting the filtering effect. Further, the interior of the filter chamber 8 filters the sewage through the central filter plate 22 and the flexible filter screen 26, and the filtered impurities accumulate inside the flexible filter screen 26. When the movable filter plate 9 rotates with the rotating cylinder 16, the counterweight device 19 inside the connecting rod 20 causes the movable rod 25 to move away from the movable groove 24 under the action of centrifugal force, and the weight density of the counterweight device 19 is relatively high. The specific counterweight device 19 can be selected from a high-density solid casting such as metal copper. A rotating shaft 21 is provided inside the rotating groove 23. When the counterweight device 19 moves in the direction away from the connecting rod 20, the connecting rod 20 can be driven to rotate with the rotating shaft 21 inside the rotating groove 23 as the fulcrum through the lever principle. The central filter plate 22 is raised relative to the flexible filter screen 26, so that the debris on the surface of the flexible filter screen 26 passes through the flexible filter screen 26 and slides into the interior of the collection bin 10 through the rotating groove 23 for collection. At the same time, the rotating dial plate 15 rotates to drive the aeration device body 30 and the rotating aeration plate 28 to rotate, thereby driving the liquid in the filter chamber 8 to be centrifugally filtered. Furthermore, an outlet pipe 31 is provided in the rotating aeration plate 28. The outlet pipe 31 is connected to the annular air cavity 14 through an annular air gap 32, and the outlet pipe 31 is arranged at a tangent angle. The gas is blown into the interior of the annular air gap 32 and the outlet pipe 31 through the inlet pipe 4, and the gas is finally discharged into the interior of the aeration bin 18 through the outlet pipe 31. When the gas is discharged through the outlet pipe 31, it will form a rotational thrust on the rotating aeration plate 28.Thus, the rotating aeration device 13 can rotate autonomously under the power of gas without the need for long-term pushing. At the same time, the gas can adjust the oxygen content and other components as needed, so that the biological sludge and sewage in the aeration bin 18 are mixed more fully while providing air components for the aerobic reaction. Compared with the traditional aeration device, the air flow of the rotating aeration device 13 is in a rotating state during aeration, which makes the air flow more dispersed and can further promote the mixing of the activated sludge and sewage, thereby improving the aeration treatment effect. Furthermore, a one-way conduction is formed on the outlet pipe 31 through the one-way baffle 39 to avoid the backflow of sewage or activated sludge inside the aeration bin 18. When air flows through the annular air gap 32, the air flow pushes the one-way baffle 39 to rotate and compresses the spring 37, so that a gap is generated between the one-way baffle 39 and the limit block 38 for air flow to pass through. Similarly, when the annular When no air flows through the air gap 32, the one-way baffle 39 is pressed against the limit block 38 by the action of the spring 37 to prevent the sewage or activated sludge from flowing back. The rotating aeration plate 28 is driven by the gas to rotate and centrifugally filter the sewage in the filter chamber 8. During the centrifugal filtration, the rotating aeration plate 28 can drive the driving gear 36 to rotate through the tooth groove 29. The driving gear 36 drives the rotating rod 34 to rotate. The rotation of the rotating rod 34 also drives the rotation of the cleaning brush 33 and the spiral blade 35. The rotation of the spiral blade 35 can make the sludge at the bottom of the aeration bin 18 float up, preventing the accumulation of activated sludge and affecting the filtration effect. At the same time, the fine filter 11 can be cleaned by the rotation of the cleaning brush 33 to prevent the fine filter 11 from being blocked. The aeration plate 28 is driven to rotate, and the filtration effect is further improved during the aeration process.
