[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] The precipitation system according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1-4 As shown, the sedimentation system 100 according to an embodiment of the present invention includes a tank body 1, a water distribution assembly 2, a mud-water separation assembly 3 and a vibration assembly 6.

[0034] The tank body 1 has a chamber, a water outlet and a mud outlet, both of which are connected to the chamber, the water outlet is arranged at the upper end of the tank body, and the mud outlet is arranged at the lower end of the tank body. Figure 1-2 As shown, the pool body 1 can be generally cylindrical and extends in the up-down direction, the water outlet is arranged at the upper end of the pool body, and the mud discharge port is arranged at the lower end of the pool body.

[0035] The water distribution component 2 is arranged in the chamber and is suitable for passing sewage into the chamber. The water distribution component 2 is used to evenly distribute the sewage in the chamber. Specifically, Figure 1-2As shown, the water distribution assembly 2 can be fixed to the inner circumferential surface of the tank body 1 by fasteners (such as screws or bolts), and the water distribution assembly 2 can evenly discharge sewage into the chamber.

[0036] The mud-water separation assembly 3 is arranged in the chamber and above the water distribution assembly 2. The mud-water separation assembly 3 includes a central tube 31 and a plurality of separation plates 32. The central tube 31 is arranged in the tank body 1. The inner circumference of the central tube 31 defines a separation cavity. The central tube 31 is provided with a plurality of through holes (not shown in the figure) penetrating the central tube 31 in the inner and outer directions. Specifically, Figure 1-2 As shown, the mud-water separation component 3 is arranged in the tank body 1 and is spaced apart from the water distribution component 2 in the up-down direction. The central tube 31 is a cylinder extending in the up-down direction. The central tube 31 can be fixed in the tank body 1 by a connecting rod. The upper end of the central tube 31 defines a water outlet connected to the separation chamber, and the lower end of the central tube 31 defines a slag discharge port connected to the separation chamber. A plurality of through holes define a plurality of rows in the up-down direction, and each row includes a plurality of through holes extending along the circumference of the central tube 31.

[0037] A plurality of separation plates 32 are arranged on the central tube 31 at intervals in the vertical direction, and the outer circumference of each separation plate 32 and the inner circumference of the tank body 1 are arranged at intervals in the inner and outer directions to form a water inlet cavity, so that the sewage flowing out of the water distribution component 2 flows into the mud-water separation component 3 through the water inlet cavity. The separation plates 32 extend from the inside to the outside and are inclined upward. The separation plates 32 are used to separate the mud residue in the sewage so that the sewage is separated into clean water and mud residue. At least one through hole is located between two adjacent separation plates 32, so that the separated mud residue and clean water flow into the central tube 31 through the through hole. Specifically, as Figure 1-2 As shown, the separation plate 32 is a trumpet-shaped circular plate with an opening facing upward, and a plurality of separation plates 32 are fixed on the central tube 31 at equal intervals in the vertical direction. A circle of through holes is provided between two adjacent separation plates 32, and the through holes are provided adjacent to the lower separation plate 32. The sewage flows upward through the water distribution component 2, so that the sewage flows into the space between the two adjacent separation plates 32 through the water distribution component 2. The sewage is separated into muddy water between the two adjacent separation plates 32, and the mud residue falls on the separation plate 32 under the action of gravity. The separation plate 32 separates the muddy water to separate the sewage into clean water and mud residue, and the mud residue flows into the dividing chamber through the through holes with the water flow to reduce dust. The mud residue is discharged from the mud-water separation component 3 from the slag discharge port under the action of gravity and falls into the bottom of the tank body 1. The clean water continues to flow upward through the water outlet under the action of the water flow. Thus, the mud residue in the muddy water is removed by the mud-water separation component 3.

[0038] The vibration component 6 is arranged on the outer peripheral side of the pool body 1 and connected to the mud-water separation component 3. The vibration component 6 is used to drive the mud-water separation component 3 to vibrate to clean the mud residue on the mud-water separation component 3. Specifically, Figure 2As shown, since the SS in the sewage-water mixture is relatively high, after the sedimentation system 100 has been in operation for a period of time, the separation plate 32 and the mud settling plate 4 are prone to adhere to the sedimentation sludge, thereby affecting the sedimentation effect of the sedimentation system 100. Therefore, the vibration component 6 is connected to the central tube 31. When there is too much sediment in the mud-water separation component 3, the vibration component 6 can be turned on to drive the mud-water separation component 3 to vibrate to remove the sediment in the mud-water separation component 3, thereby ensuring the sedimentation efficiency and sedimentation effect of the mud-water separation component 3.

[0039] The sedimentation system 100 of the embodiment of the present invention is provided with a water distribution component 2 and a mud-water separation component 3. The water distribution component 2 allows the sewage to be evenly distributed through the water distribution component 2. The mud-water separation component 3 is provided so that the sludge can be settled between the two separation plates 32. Compared with the vertical flow type and radial flow type in the related art, the sedimentation system 100 of the embodiment of the present invention greatly reduces the footprint of the unit, improves the mud-water separation effect of the sedimentation system 100, and provides a vibration component 6 to clean the mud-water separation component 3, thereby ensuring the separation efficiency of the mud-water separation component 3.

[0040] In some embodiments, the chamber includes a first chamber 11, a second chamber 12 and a third chamber 13 which are sequentially connected in the up-down direction, and the mud-water separation assembly 3 is disposed in the second chamber 12. Specifically, Figure 2 As shown, the first chamber 11 is arranged above the second chamber 12 and is connected to the second chamber 12, the second chamber 12 is arranged above the third chamber 13 and is connected to the third chamber 13, the first chamber 11 is a clarified water production area, the clean water separated from the sludge is located in the first chamber 11, the second chamber 12 is a mud-water separation area, the mud-water separation component 3 is arranged in the second chamber 12 to separate mud and water, and the third chamber 13 is a sludge discharge area.

[0041] In some embodiments, the third chamber 13 includes a first portion 131, a second portion 132, and a third portion 133 that are sequentially connected in the up-down direction. The upper and lower ends of the second portion 132 are connected to the first portion 131 and the third portion 133 respectively. The cross-sectional area of ​​the inner circumference of the second portion 132 gradually decreases from top to bottom. The cross-sectional areas of the inner circumferences of the first portion 131 and the third portion 133 are constant in the up-down direction. The water distribution assembly 2 is arranged in the first portion 131, and the third portion 133 and the lower end of the center tube 31 are arranged relative to each other in the up-down direction. In the projection plane orthogonal to the up-down direction, the third portion 133 is located in the second portion 132, and the second portion 132 is located in the first portion 131. Specifically, as Figure 2As shown, the first part 131 is arranged at the upper end of the second part 132 and the first part 131 is connected to the second part 132, the third part 133 is arranged at the lower end of the second part 132 and is connected to the second part 132, the first part 131 is a cyclone water distribution area and the water distribution component 2 is arranged in the first part 131, the second part 132 and the third part 133 are sludge discharge areas, which can make the sludge separated by the mud-water separation component 3 fall into the sludge discharge area, the first part 131 and the third part 133 are both cylindrical, the second part 132 is a truncated cone with a cross-sectional area gradually decreasing from top to bottom, and the cross-sectional area of ​​the first part 131 is equal to the cross-sectional area of ​​the upper end surface of the truncated cone, and the cross-sectional area of ​​the third part 133 is equal to the cross-sectional area of ​​the lower end surface of the truncated cone, thereby, the sludge can be collected into the third part 133 through the second part 132, so that the setting of the third chamber 13 is more reasonable.

[0042] In some embodiments, the scraper assembly 5 is disposed in the first cavity 11 and located at the top of the pool body 1. The scraper assembly 5 can rotate in the up and down directions relative to the pool body 1 so that the scraper assembly 5 can scrape away floating objects in the clean water. Figure 1-3 As shown, the scraper assembly 5 includes a scraper 51 and a motor 51. The scraper 51 is a horizontal plate extending inward and outward directions. The motor 51 is fixed above the pool body 1 and connected to the scraper 51. The lower half of the scraper 51 is located in the clean water at the upper end of the pool body 1, and the upper half of the scraper 51 is located above the clean water of the pool body 1. The scraper 51 is driven to rotate by the motor 51, so that the scraper 51 scrapes off floating objects or oil stains above the clean water.

[0043] In some embodiments, the water distribution assembly 2 has a plurality of water distribution ports (not shown in the figure) with openings facing upward, and the plurality of water distribution ports are arranged in a plurality of circles along the inner and outer directions, and each circle includes a plurality of water distribution ports arranged at intervals along the circumference of the tank body 1, so that sewage flows into the tank body 1 through the water distribution ports, and the height of the plurality of water distribution ports gradually increases from the inside to the outside. Specifically, Figure 1-2 As shown, the water distribution component 2 can be fixed on the inner circumference of the pool body 1 by fasteners (for example, screws or bolts), and the upper end surface of the water distribution component 2 is provided with a plurality of water distribution ports that penetrate the upper end surface of the water distribution component 2. The plurality of water distribution ports are arranged in multiple circles at equal intervals along the inner and outer directions, and each circle includes a plurality of water distribution ports arranged at equal intervals along the circumference of the pool body 1, and the water distribution ports of the outer circle are higher than the water distribution ports of the inner circle. The water distribution ports can be circular ports, and the aperture of the water distribution ports is preferably 2.5cm-3.5cm. The spacing between two adjacent water distribution ports in each circle of water distribution ports is 30cm-80cm, and the height of the water distribution component 2 in the vertical direction is 1.0m-2.5. As a result, the sewage is swirl-distributed from low to high through the plurality of water distribution ports, and the water is distributed at multiple points through the water distribution ports, which reduces the interference with the mud-water separation and sedimentation of the system, and the multi-point water distribution reasonably distributes the head loss and improves the ability of uniform water distribution.

[0044] In some embodiments, the water distribution assembly 2 includes a water distribution pipe, which is disposed in the third chamber 13 and spirally extends upward from the inside to the outside, and a plurality of water distribution ports are arranged at intervals along the extension direction of the water distribution pipe. Thus, the sewage is swirl-distributed from low to high through the water distribution pipe, making the arrangement of the water distribution assembly 2 more reasonable.

[0045] In some embodiments, the separation plate 32 is a bucket-type structure and the interlayer spacing between two adjacent separation plates 32 is 200cm-500cm, the center diameter of the bucket part of the separation plate 32 is 200cm-500cm, and the diameter area of ​​the separation plate 32 should be smaller than the area of ​​the outermost water distribution pipe in the cyclone water distribution area, and should be 0.4-0.7 times the diameter of the outermost water distribution pipe. In this way, the influence of the water distribution flow on the sedimentation process of the sediment in the central tube 31 can be effectively reduced.

[0046] In some embodiments, the central tube 31 includes a first tube 311 and a second tube 312 connected in sequence along the up-down direction, a plurality of separation plates 32 are provided on the first tube 311 and a plurality of through holes are formed on the first tube 311, the cross-sectional area of ​​the inner circumference of the first tube 311 is constant from top to bottom, and the cross-sectional area of ​​the inner circumference of the second tube 312 gradually increases from top to bottom. Specifically, as Figure 1-2 As shown, the first cylinder 311 is arranged on the second cylinder 312, and the first cylinder 311 is a vertical cylinder extending in the up-down direction, and the second cylinder 312 is a trumpet-shaped whose inner circumferential cross-sectional area gradually decreases from top to bottom. The separation plate 32 and the through hole are both formed on the first cylinder 311, and the slag discharge port is formed at the lower end of the second cylinder 312, thereby allowing the mud residue in the center cylinder 31 to be smoothly discharged from the second cylinder 312 to prevent the mud residue from being blocked in the second cylinder 312.

[0047] In some embodiments, the sedimentation system 100 further includes a plurality of sedimentation plates 4, which are arranged in the third chamber 13 along the up-down direction and are located below the second tube 312. The sedimentation plates 4 are provided with sedimentation ports 41 that penetrate the sedimentation plates 4 along the up-down direction. Two adjacent sedimentation ports 41 are arranged opposite to each other along the up-down direction and are located above the first chamber 11. The sedimentation plates 4 extend in the inside-out direction and are inclined upward, so that the sludge falls into the first chamber 11 through the plurality of sedimentation plates 4. In the projection plane orthogonal to the up-down direction, the sedimentation ports 41 are located in the second tube 312, and the center tube 31 is located in the sedimentation plates 4. Specifically, as Figure 1-2As shown, the silt plate 4 can be fixedly connected to the center tube 31 by fasteners or connecting rods, and the silt plate 4 is located in the first part 131 and the second part 132, and a plurality of silt plates 4 are relatively arranged below the center tube 31 at equal intervals in the up and down directions, and the silt plate 4 is funnel-shaped with an inner circumference gradually decreasing from top to bottom, and a silt port 41 is formed at the lower end of the silt plate 4, thereby allowing the sludge to further settle on the silt plate 4, and the angle between the extension direction of the silt plate 4 and the horizontal distance is preferably 55°-35°. Compared with the traditional sludge hopper, the burial depth of the sludge area is reduced, saving construction costs.

[0048] In some embodiments, the vibration assembly 6 includes a vibration controller 61 and an ultrasonic sensor (not shown in the figure), both of which are arranged on the outer periphery of the tank body 1, and the vibration controller 61 is connected to the central tube 31 and the ultrasonic sensor respectively, and the ultrasonic sensor is used to detect the thickness of the sediment on the surface of the separation plate 32, so that when the ultrasonic sensor detects that the thickness of the sediment on the surface of the separation plate 31 is higher than a preset value, the vibration controller 61 is turned on to clean the mud residue on the separation plate. Specifically, Figure 2 As shown, the vibration assembly 6 includes a vibration controller 61, a transmission shaft and an ultrasonic sensor. The vibration controller 61 and the ultrasonic sensor are both fixedly mounted on the outer peripheral side of the pool body 1. The vibration controller 61 is connected to the mud-water separation assembly 3 through the transmission shaft, so that the vibration controller 61 drives the mud-water separation assembly 3 and the multiple mud plates 4 to vibrate to remove the sludge on the mud-water separation assembly 3 and the multiple mud plates 4. The ultrasonic sensor is arranged on the outer peripheral side of the pool body. Thus, the ultrasonic sensor is used to detect the thickness of the sediment on the plate surface in real time. According to the data transmitted by the ultrasonic sensor, the vibration controller 61 can be automatically started or shut down for mud removal, which effectively solves the problem of sediment accumulation on the separation plate 32 and the mud plate 4. Compared with the inclined plate (tube) structure in the related technology, there is no need for regular replacement and backwashing, which extends the service life and maintenance cost of the sedimentation system 100.

[0049] In some embodiments, the sedimentation system 100 further includes an overflow weir 7, which is disposed in the cylinder 1 and located at the upper end of the cylinder 1. The overflow weir 7 extends along the inner circumference of the tank body 1, and the outer circumference of the overflow weir 7 and the inner circumference of the tank body 1 are spaced apart in the inner and outer directions to form a water collection tank. The clean water in the tank body 1 overflows into the water collection tank through the overflow weir 7. The scraper assembly 5 is located in the overflow weir 7 and can rotate relative to the overflow weir 7 in the up and down directions. Specifically, as Figure 1-3As shown, the overflow weir 7 is generally annular, and the overflow weir 7 is fixedly mounted on the upper end of the first cavity 11, and the outer circumferential surface of the overflow weir 7 and the inner circumferential surface of the tank body 1 are spaced apart in the inner and outer directions to form a water collecting tank. The overflow weir 7 is arranged above the first cavity 11, thereby allowing the clean water in the first cavity 11 to flow into the overflow weir 7 and evenly overflow and flow into the water collecting tank, thereby further removing impurities in the clean water. The scraper assembly 5 is arranged in the overflow weir 7 and can rotate in the overflow weir 7, thereby collecting floating objects in the overflow weir 7 through the scraper assembly 5.

[0050] In some embodiments, the sedimentation system 100 further includes a first sewage pipe 8 and a second sewage pipe 9 .

[0051] One end of the drain pipe is located below the scraper assembly 5, and the other end of the first drain pipe 8 passes through the tank body 1, so that the floating objects in the first cavity 11 are discharged out of the first cavity 11 through the first drain pipe 8. Figure 1-3 As shown, the inlet of the sewage pipe is located below the scraper assembly 5 and is arranged adjacent to the inner circumference of the overflow weir 7, and the outlet of the sewage pipe is located outside the tank body 1 and is connected to the sewage pump, thereby floating objects in the overflow weir 7 are discharged outside the tank body 1 through the sewage pipe and the sewage pump.

[0052] One end of the second sewage pipe 9 is connected to the bottom of the third chamber 13, and the other end of the second sewage pipe 9 extends out of the tank body 1, so that the mud in the third chamber 13 can be discharged through the second sewage pipe 9. Figure 1-3 As shown, the inlet of the second sewage pipe 9 is connected to the third part 133 of the third chamber 13, and the outlet of the second sewage pipe 9 extends out of the tank body 1. The sludge in the third chamber 13 can be discharged out of the third chamber 13 through the second sewage pipe 9 by static pressure sludge discharge. In order to ensure the stability of the sludge discharge system, a sludge discharge pump can be installed at the end of the second sewage pipe 9 to assist in sludge discharge or emptying the tank body 1.

[0053] It is worth noting that a control valve and a sampling tube can be set on the second sewage pipe 9. According to the sludge properties observed by the sampling tube, the sludge discharge process is opened and closed by the valve. The sampling tube can also serve as a flushing tube to regularly clean the second sewage pipe 9 to reduce sludge accumulation in the second sewage pipe 9.

[0054] In some embodiments, the precipitation system 100 further includes a first tube 10 and a second tube 101 .

[0055] The first pipe 10 is located outside the tank body 1 and is connected to the second sewage pipe 9 and the first pipe 10 is connected adjacent to the outlet of the second sewage pipe 9. Figure 1 As shown, the first tube 10 can be used as a sampling tube to sample the mud and dirt in the second sewage pipe 9, and the first tube 10 can also be used as a flushing tube to flush the second sewage pipe 9 to prevent the second sewage pipe 9 from being blocked.

[0056] The second pipe 101 is located outside the tank body 1 and is connected to the second sewage pipe 9. The second pipe 101 is located between the first pipe 10 and the inlet of the second sewage pipe 9. Figure 1 and Figure 4 As shown, the inlet of the second pipe 101 is connected to the second sewage pipe 9, and the second pipe 101 can be a static pressure mud discharge air guide pipe or a flushing pipe to ensure that the static pressure mud discharge is stable.

[0057] In some embodiments, the sedimentation system 100 also includes an underwater camera, which is arranged in the chamber and opposite to the mud-water separation component 3, so that the user can more intuitively form an image of the sedimentation process in the vibration controller through the underwater camera, thereby improving the system's self-control and operation and maintenance capabilities.

[0058] In some embodiments, Figure 5 As shown, the separation plate 32 has a plurality of annular plates 321 and a plurality of annular grooves 322 along the inner and outer directions, and the plurality of annular plates 321 and the plurality of annular grooves 322 are arranged alternately in sequence along the inner and outer directions, and the annular grooves 322 extend along the circumference of the central tube 31 and are concave downward, and the annular plates 321 extend from the outside to the inside and are inclined from the top to the bottom, and an annular plate 321 is connected to both the inner and outer sides of each annular groove 322. Thus, the sludge can slide into the annular groove 322 through the annular plates 321, reducing the probability of the sludge being suspended again, reducing the probability of the sludge flowing into the central tube 31, and improving the sedimentation efficiency of the sedimentation system 100.

[0059] In some embodiments, Figure 5 As shown, the sedimentation system 100 also includes a mounting tube 33, a plurality of first dust suppression plates 34 and a plurality of second dust suppression plates 35. The mounting tube 33 is arranged above the central tube 31. The mounting tube 33 is trumpet-shaped, and the lower end of the mounting tube 33 is connected to the outer circumference of the upper end of the dust suppression plate, and the upper end of the mounting tube 33 is connected to the inner circumference of the pool body. The plurality of first dust suppression plates 34 and the plurality of second dust suppression plates 35 are all arranged in the mounting tube 33 and located above the central tube 31. The plurality of first dust suppression plates 34 and the plurality of second dust suppression plates 35 are alternately arranged in the mounting tube 33 at intervals, and the first dust suppression plate 34 is arranged on one side of the mounting tube 33 and is spaced from the other side of the mounting tube 33, and the first dust suppression plate 34 is arranged on the other side of the mounting tube 33 and is spaced from one side of the mounting tube 33, and in the projection plane orthogonal to the up and down directions, the free end of the first dust suppression plate 34 and the free end of the second dust suppression plate 35 overlap. Therefore, the first dust suppression plate 34 and the second dust suppression plate 35 can further reduce dust in the water flowing out of the installation tube 33, thereby improving the sedimentation efficiency of the sedimentation system 100.

[0060] The following is based on the attached Figure 1-4As shown, the sedimentation system 100 of an embodiment of the present invention is specifically described. The tank body 1 can be divided into the following five areas according to the water flow direction: a cyclone water distribution area (the first part 131), a mud-water separation area (the second chamber 12), a clarified water production area (the first chamber 11), a sludge discharge area (the second part 132 and the third part 133), and a vibration mud removal area.

[0061] (1) Swirling water distribution area.

[0062] The water distribution component 2 is arranged in the cyclone water distribution area, and the sewage enters the perforated water distribution pipe for water distribution through the water inlet pipe 21. The perforated pipe is a spiral ascending structure, and cyclone water distribution is carried out from low to high. Water distribution is carried out at multiple points through openings, which reduces the interference with the separation and sedimentation of mud and water in the system. Multi-point water distribution reasonably distributes the head loss and improves the ability of uniform water distribution.

[0063] (2) Mud-water separation area.

[0064] A plurality of separation plates 32, a plurality of mud settling plates 4, and a central tube 31 are all arranged in the mud-water separation area.

[0065] Multiple layers of separation plates 32 are arranged in parallel downward along the inner periphery of the tank body 1. The separation plates 32 are of bucket-type structure. The distance between the separation plates 32 and the tank wall is 500-1000 cm, and the spacing between each layer of separation plates 32 is 400-800 cm. The center of the separation plate 32 bucket-type structure is a central trumpet structure, and the diameter of the central tube 31 is 500-1200 cm. The muddy and water mixed liquid is separated between the separation plates 32, and the clear water rises along the water flow direction and enters the clarified water production area of ​​the tank body. The water flow rising path is shown in the attached figure. Figure 1 As shown in the cross-sectional view. The separated sediment (e.g., sludge) will enter the center tube 31 along the bottom of the separation plate 32 and settle. Entering the bucket-type sedimentation plate 4 below the center of the structure, the sediment continues to settle along the designed path of the sedimentation plate 4 to the sludge discharge area. The interlayer spacing of the sedimentation plate 4 should be 200-500cm, the center diameter of the bucket of the sedimentation plate 4 should be 200-500cm, and the diameter area of ​​the sedimentation plate 4 should be smaller than the area of ​​the first layer of water distribution pipes in the cyclone water distribution area, and should be 0.4-0.7 times the diameter of the first layer of water distribution pipes. This can effectively reduce the impact of the water distribution flow on the sedimentation process of the sediment in the center tube 31.

[0066] (3) Clarify the water production area.

[0067] The scraper assembly 5, the slag hopper, the water collecting trough, the guide plate and the overflow weir 7 are all arranged in the clarified water production area.

[0068] After passing through the mud-water separation area, the water flow continues to rise and enters the clarified water production area of ​​the system, and then enters the water collection tank along the direction of the guide plate to discharge water. The scum particles with lower density in the water float to the water surface, and the drive motor 51 drives the scraper 51 to rotate, thereby collecting the scum. The concentrated scum is pushed into the slag discharge bucket and removed through the slag discharge pipe, which can effectively reduce the concentration of suspended matter in the produced water and improve the effect of mud-water separation.

[0069] (4) Sludge discharge area.

[0070] The sediment produced by the mud-water separation reaction of the system sinks into the mud hopper at the bottom of the tank body 1. After the system mixed sewage is effectively separated in the mud-water separation area, the sediment can be efficiently settled along the central tube 31 and the mud settling plate 4 and enter the sludge discharge area. The angle between the bottom of the sludge hopper and the horizontal distance is preferably 55-35°. Compared with the traditional sludge hopper, the burial depth of the sludge area is reduced, and the construction cost is saved. The bottom of the sludge discharge area is partially set as a mud discharge trough, so that the system is more efficient whether it uses static pressure mud discharge or pipeline pressure mud discharge.

[0071] The sludge is discharged by static pressure, which saves energy and reduces consumption. Control valves and sampling tubes are set on the sludge discharge pipe and static pressure sludge discharge air pipe. The sludge discharge process is opened and closed by the valve according to the sludge properties observed by the sampling tube. The air pipe and sampling tube can also be used as flushing pipes to regularly clean the sludge discharge pipe to reduce the sludge accumulation in the pipeline. In order to ensure the stability of the sludge discharge system, a sludge discharge pump is installed at the end of the sludge discharge pipe to assist in sludge discharge or emptying the tank body 1.

[0072] (5) Vibration mud removal area: It is mainly composed of a vibration controller 61, a transmission shaft and an ultrasonic sensor.

[0073] Since the SS in the sewage-water mixture is relatively high, after the system has been in operation for a period of time, the mud-water separation plate 32 and the mud settling plate 4 are prone to adhere to the sedimentation sludge, thereby affecting the sedimentation effect of the system. Conventional traditional practices use high-pressure ventilation or high-pressure water to backwash the plates to wash away the sludge on the surface of the plates to reduce the sedimentation adhering to the system.

[0074] This patent adopts high-frequency and low-intensity vibration to remove sediment on the plate layer, and the vibration frequency is preferably 30,000-50,000 times / minute. The vibration controller 61 is located outside the system and is connected to the mud-water separation area through a transmission shaft. In addition, an ultrasonic sensor is installed in the mud-water separation area to detect the thickness of the sediment on the plate surface in real time. According to the data transmitted by the sensor, the vibration mud removal can be automatically started or shut down. In this way, the problem of sediment accumulation on the mud-water separation plate 32 and the mud settling plate 4 can be solved, and a separate backwashing design is not required, which reduces the energy consumption of the system and does not affect the normal operation of the system.

[0075] According to the investment, an underwater camera can be appropriately added to form a more intuitive image of the sedimentation process in the vibration controller 61, thereby improving the self-control and maintenance capabilities of the system.

[0076] In summary, the precipitation system 100 according to the embodiment of the present invention has the following advantages:

[0077] 1.

No separate backwashing design is required, which reduces system energy consumption and does not affect the normal operation of the system.

[0081] 5.
