Description

Technical Field

Background Technology

[0002] Controlling the sludge settling ratio in the clarification zone of a high-density sedimentation tank is crucial for its stable and efficient operation, which is also a core component for wastewater reuse. The sludge discharge time, discharge volume, and sludge return flow of the high-density sedimentation tank are all controlled by adjusting the sludge settling ratio in the clarification tank. However, in actual operation, due to varying operating conditions such as changes in influent water quality and chemical dosage, the treatment effect can be affected, leading to substandard effluent quality. Therefore, continuous and accurate measurement of SV30 is essential to improve effluent quality and conserve chemical dosage.

[0003] The core objective of the SV30 online monitoring device for high-density sedimentation tanks is to acquire sludge settling performance data in real time and accurately. However, in actual operation, the influent to the sedimentation tank often contains suspended debris such as aquatic plants, fibers, and plastics. If these debris directly enters the monitoring device, it may clog the sampling pipes, interfere with settling observations, and in severe cases, damage critical components such as the sampling pump and sensors.

[0004] Therefore, there is an urgent need to improve an online monitoring device for high-density sedimentation tanks (SV30) to solve the aforementioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown in the figure, this embodiment provides an example of an online monitoring device for SV30 in a high-density sedimentation tank.

[0026] A high-density sedimentation tank online monitoring SV30 device includes a measuring cylinder 1 and a sampling pump 2. Multiple sedimentation plates 3 are fixedly mounted on the sampling pump 2. The sampling pump 2 is connected to the measuring cylinder 1 via a delivery pipe 4. A winding structure 5 is provided on the sampling pump 2. The winding structure 5 includes a drive motor 6 fixedly mounted on the top of the sampling pump 2, a first gear 7 fixedly mounted on the output end of the drive motor 6, a rotating rod 8 movably mounted inside the sampling pump 2, multiple winding rods 9 fixedly mounted on the rotating rod 8, and a second gear 10 meshing with the first gear 7 fixedly mounted at one end of the rotating rod 8. A first water pump 11 connected to the sampling pump 2 is installed at one end of the delivery pipe 4. A discharge port 12 is provided below the measuring cylinder 1. The winding structure 5 changes the traditional method of obtaining sludge for high-density sedimentation tank online monitoring SV30, allowing suspended solids such as aquatic plants, fibers, and plastics mixed in the sedimentation tank to be separated after entering the sampling pump 2. First, multiple sedimentation trays 3 are used to collect the sludge. Then, the collected sludge enters the sampling pump 2. The drive motor 6 is then started, which drives the first gear 7 to rotate. Due to the connection between the first gear 7 and the second gear 10, the second gear 10 drives the rotating rod 8 to rotate when the first gear 7 rotates. The multiple winding rods 9 on the rotating rod 8 can wrap and collect suspended matter such as aquatic plants, fibers, and plastics, thereby separating them from the sludge. Then, the first water pump 11 is started to transport the treated sludge through the conveying pipe 4 to the measuring cylinder 1 for monitoring. After the online monitoring of the sludge SV30 is completed, the sludge is finally discharged through the drain port 12. The advantage of this structure is that it can prevent debris from entering the monitoring device and clogging the sampling pipe, and it can also prevent debris from interfering with sedimentation observation. It can also reduce the probability of damage to key components such as the sampling pump 2 and the sensor.

[0027] like Figure 3As shown, a protective housing 13 connected to the sampling pump 2 is fixedly installed on the outside of the drive motor 6. The protective housing 13 has multiple heat dissipation holes 14, and a maintenance cover 15 is provided at one end of the protective housing 13. The protective housing 13, the heat dissipation holes 14, and the maintenance cover 15 can protect the drive motor 6 and prevent it from being damaged by collision. At the same time, the multiple heat dissipation holes 14 on the protective housing 13 can dissipate the heat generated by the drive motor 6 during operation, preventing the internal temperature of the protective housing 13 from becoming too high and causing the drive motor 6 to malfunction. The maintenance cover 15 allows personnel to inspect the drive motor 6 without disassembling the protective housing 13, thereby saving personnel time in inspecting the drive motor 6.

[0028] like Figure 3 As shown, a first magnetic ring 16 is fixedly installed on the inner side of the inspection cover 15, and a second magnetic ring 17 is fixedly installed on the protective shell 13 and magnetically connected to the first magnetic ring 16. Through the arrangement of the first magnetic ring 16 and the second magnetic ring 17, the two attract each other and can fix the inspection cover 15 on the protective shell 13 to prevent it from falling off. Due to the characteristics of the first magnetic ring 16 and the second magnetic ring 17, the inspection cover 15 can be opened without tools, thereby saving personnel time in opening the inspection cover 15.

[0029] like Figure 4 As shown, a first water inlet pipe 18 is fixedly installed on the top of the measuring cylinder 1. One end of the first water inlet pipe 18 is connected to a second water inlet pipe 19. A second water pump 20 is installed on the second water inlet pipe 19. Through the arrangement of the first water inlet pipe 18, the second water inlet pipe 19 and the second water pump 20, after the sludge inside the measuring cylinder 1 has been discharged, the second water inlet pipe 19 is connected to the first water inlet pipe 18, and the second water pump 20 is started to transport water through the second water inlet pipe 19 and the first water inlet pipe 18 to the inside of the measuring cylinder 1, so as to wash the sludge remaining inside the measuring cylinder 1. The wastewater after washing can flow out again through the drain outlet 12.

[0030] like Figure 4 As shown, a first retaining plate 21 and a second retaining plate 22 are fitted at the connection between the second water inlet pipe 19 and the first water inlet pipe 18. A plurality of limiting rods 23 are fixedly installed on one side of the first retaining plate 21. A plurality of limiting holes 24 adapted to the limiting rods 23 are opened on the second retaining plate 22. After the second water inlet pipe 19 and the first water inlet pipe 18 are connected together by the first retaining plate 21, the second retaining plate 22, the limiting rods 23 and the limiting holes 24, the first retaining plate 21 and the second retaining plate 22 are fitted at the connection between the two. When the first retaining plate 21 and the second retaining plate 22 are in contact, the limiting rods 23 can be inserted into the interior of the limiting holes 24, thereby fixing the first retaining plate 21 and the second retaining plate 22 together and preventing the first retaining plate 21 and the second retaining plate 22 from falling off the first water inlet pipe 18 and the second water inlet pipe 19.

[0031] like Figure 5 and Figure 6 As shown, a fixing plate 25 is fixedly installed on one side of the measuring cylinder 1, and an electric telescopic rod 26 is fixedly installed at the bottom of the fixing plate 25. A fixing block 27 is fixedly installed at the output end of the electric telescopic rod 26, and a fixing ring 28 is fitted on the fixing block 27. A stop block 29 is fixedly installed at the bottom of the fixing ring 28. A slot 30 adapted to the stop block 29 is opened on the drain port 12. With the arrangement of the fixing plate 25, electric telescopic rod 26, fixing block 27, fixing ring 28, stop block 29 and slot 30, starting the electric telescopic rod 26 can drive the stop block 29 to move up and down. When the stop block 29 is inserted from the slot 30 into the drain port 12, it can seal the drain port 12, thereby preventing the sludge inside the measuring cylinder 1 from flowing out of the drain port 12 during monitoring. When the electric telescopic rod 26 retracts and the stop block 29 is disengaged from the drain port 12, the sludge can be discharged from the measuring cylinder 1. This structure eliminates the need for manual operation of the drain port 12, thus saving labor.

[0032] like Figure 6 As shown, both the fixing block 27 and the fixing ring 28 have connecting holes 31. A rod 32 is movably installed inside the connecting hole 31. A latch 33 is fixedly installed at one end of the rod 32. By setting up the connecting hole 31, the rod 32, and the latch 33, the rod 32 is inserted into the connecting hole 31. After rotating the rod 32 to adjust the angle of the latch 33 to be perpendicular to the angle of the connecting hole 31, the fixing block 27 can be fixed inside the fixing ring 28 to prevent it from falling off. When the rod 32 is rotated in the opposite direction to adjust the angle of the latch 33 to be consistent with the angle of the connecting hole 31, the rod 32 can be pulled out from the connecting hole 31, which makes it convenient for personnel to disassemble and replace the stop 29 when it is damaged.

[0033] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the online monitoring device for SV30 in a high-density sedimentation tank provided in this embodiment is as follows:

[0034] First, multiple sedimentation trays 3 are used to collect the sludge. Then, the collected sludge enters the sampling pump 2. The drive motor 6 is then started to drive the first gear 7 to rotate. Due to the connection between the first gear 7 and the second gear 10, the second gear 10 drives the rotating rod 8 to rotate when the first gear 7 rotates. The multiple winding rods 9 on the rotating rod 8 can wrap and collect suspended matter such as aquatic plants, fibers, and plastics, thereby separating them from the sludge. Then, the first water pump 11 is started to transport the treated sludge through the conveying pipe 4 to the measuring cylinder 1 for monitoring. After the online monitoring of the sludge SV30 is completed, the sludge is finally discharged through the drain port 12.
