Description

Technical Field

[0001] This application relates to the technical field of sludge settling ratio detection equipment, and in particular to an automatic sampling and monitoring device for sludge settling ratio. Background Technology

[0002] Currently, in wastewater commissioning and operation, the sludge settling ratio (SV) reflects the quality of sludge settling performance. By observing the sludge settling ratio, including sludge settling rate, sludge color, and clarity of the supernatant, it can be determined whether the sludge is in an abnormal condition and what kind of abnormality it is. For example, if the sludge settling ratio is high, the sludge-water interface is clear, and the supernatant is clear, this situation is generally due to poor sludge settling performance, but with good activity, usually caused by an excessive number of filamentous bacteria. In this case, it may be sludge bulking.

[0003] The sludge settling ratio (SV) observation, including sludge settling rate, sludge color, and clarity of supernatant, can be fully recorded using a high-definition camera. Furthermore, a neural network algorithm is used to perform deep learning on the observed sludge anomalies under various conditions (sludge settling rate, sludge color, and clarity of supernatant) so that the software can ultimately determine whether each incoming sample of activated sludge is abnormal.

[0004] In related technologies, the sludge settling ratio (SV) test involves manually taking a sludge mixture and letting it settle in a 1000ml graduated cylinder. The sludge settling rate, sludge color, and clarity of the supernatant are then manually observed after a certain period of time. This process is repetitive and tedious, and the judgment of abnormal sludge conditions varies to some extent from person to person. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0020] This application discloses an automatic sampling and monitoring device for sludge settling ratio, referring to... Figure 1 In this embodiment, the automatic sludge settling ratio sampling and monitoring device includes a monitoring box 1, a transparent negative pressure storage cylinder 2, a transparent measuring cylinder 3, a first extraction mechanism, a second extraction mechanism, and a network camera 5. The transparent negative pressure storage cylinder 2 is installed inside the monitoring box 1; the transparent measuring cylinder 3 is also installed inside the monitoring box 1, located to the left of the transparent negative pressure storage cylinder 2, and both the transparent measuring cylinder 3 and the transparent negative pressure storage cylinder 2 are placed vertically.

[0021] Preferably, a liquid level controller 31 is also installed on the top side of the transparent measuring cylinder 3; the liquid level controller 31 ensures that the liquid level in the transparent measuring cylinder 3 will not overflow and is controlled at the required height.

[0022] Meanwhile, the first extraction mechanism is located on one side of the monitoring box 1, and the output end of the first extraction mechanism is connected to the inlet end on the top side of the transparent negative pressure storage tank 2. The input end of the first extraction mechanism is connected to the external sludge tank 4, so as to extract the sludge mixture in the sludge tank 4 into the transparent negative pressure storage tank 2, thereby storing the sludge mixture inside the transparent negative pressure storage tank 2 for subsequent extraction and monitoring.

[0023] Specifically, refer to Figure 1In this embodiment, the first extraction mechanism includes a first extraction component 6, a first suction pipe 61, and a first delivery pipe 62. The first extraction component 6 is installed between the sludge tank 4 and the monitoring box 1. One end of the first suction pipe 61 is connected to the input end of the first extraction component 6, and the end of the first suction pipe 61 away from the first extraction component 6 extends into the interior of the sludge tank 4. One end of the first delivery pipe 62 is connected to the output end of the first extraction component 6, and the end of the first delivery pipe 62 away from the first extraction component 6 is connected to the input end on one side of the top of the transparent negative pressure storage cylinder 2.

[0024] More specifically, the first extraction component 6 is an extraction device combining a water pump and a motor; both the first suction pipe 61 and the first delivery pipe 62 use DN20 pipes.

[0025] When the water pump and motor are started, the first suction pipe 61 draws out the sludge mixture in the sludge tank 4, and then draws it out through the first water delivery pipe 62 to the inside of the transparent negative pressure storage tank 2, so as to facilitate the storage of the sludge mixture in the sludge tank 4 in the transparent negative pressure storage tank 2.

[0026] In addition, the second extraction mechanism is located inside the monitoring box 1, and the output end of the second extraction mechanism is connected to the liquid inlet at the top of the transparent measuring cylinder 3, and the input end of the second extraction mechanism is connected to the liquid outlet at the bottom of the transparent negative pressure storage cylinder 2, so as to extract the sludge mixture stored in the transparent negative pressure storage cylinder 2 into the transparent measuring cylinder 3, thereby allowing the sludge mixture to remain stationary in the transparent measuring cylinder 3 for subsequent monitoring and processing.

[0027] Specifically, refer to Figure 1 In this embodiment, the second extraction mechanism includes a second extraction component 7, a second suction pipe 71, and a second delivery pipe 72. The second extraction component 7 is installed inside the monitoring housing 1 and is located on the right side of the transparent negative pressure storage cylinder 2. One end of the second suction pipe 71 is connected to the input end of the second extraction component 7, and the end of the second suction pipe 71 away from the second extraction component 7 is connected to the outlet end at the bottom of the transparent negative pressure storage cylinder 2. One end of the second delivery pipe 72 is connected to the output end of the second extraction component 7, and the end of the second delivery pipe 72 away from the second extraction component 7 is connected to the input end at the top of the transparent measuring cylinder 3.

[0028] More specifically, the second extraction component 7 is also an extraction device combining a water pump and a motor; the second suction pipe 71 and the second delivery pipe 72 both use DN20 pipes. Preferably, in this embodiment, the transparent negative pressure storage cylinder 2 can also act as a buffer between the transparent measuring cylinder 3 and the sludge tank 4.

[0029] When the water pump and motor are started, the second suction pipe 71 draws out the sludge mixture stored in the transparent negative pressure storage cylinder 2, and then draws it out through the second water delivery pipe 72 to the inside of the transparent measuring cylinder 3, so that the sludge mixture can be stored in the transparent measuring cylinder 3 for subsequent monitoring after settling.

[0030] In addition, refer to Figure 1 In this embodiment, the network camera 5 is installed inside the monitoring housing 1, located to the left of the transparent measuring cylinder 3, and the network camera 5 cooperates with the transparent measuring cylinder 3, with the lens of the network camera 5 facing the transparent measuring cylinder 3. Meanwhile, a PLC control system 11 is also installed on the top of the monitoring housing 1, which is electrically connected to the network camera 5 to control the network camera 5.

[0031] By setting up a structure in which the network camera 5 and the PLC control system 11 work together, the network camera 5 first takes pictures of the transparent measuring cylinder 3 and the sludge mixture inside the transparent measuring cylinder 3. Then, the pictures are fed back to the PLC control system 11. The software algorithm in the PLC control system 11 then automatically determines whether the sludge is abnormal based on the pictures. If an abnormality is found, it can also determine what kind of abnormality it is. This can replace manual sludge mixture sampling and sludge settling ratio detection, thereby achieving the effect of automatic sampling.

[0032] Preferably, in this embodiment, a drain pipe 32 is also installed at the liquid outlet end of the bottom of the transparent graduated cylinder 3. The end of the drain pipe 32 away from the transparent graduated cylinder 3 extends outside the monitoring box 1 and is connected to an external collection tank. The drain pipe 32 also uses a DN20 pipe. By setting up the drain pipe 32, the sludge mixture in the transparent graduated cylinder 3 can be discharged into the collection tank along the drain pipe 32 after the sludge monitoring is completed, thereby collecting and storing the sludge mixture in the collection tank for subsequent unified processing, which facilitates the monitoring of the sludge mixture in the next time.

[0033] In this embodiment, a touchscreen 12 electrically connected to the PLC control system 11 is also installed on the top of the monitoring housing 1. This touchscreen 12 allows monitoring personnel to control the entire automatic sampling and monitoring device via its operation. Furthermore, in this embodiment, the PLC control system 11 is also electrically connected to the level controller 31, the first extraction component 6, and the second extraction component 7, respectively. This allows for unified control of the level controller 31, the first extraction component 6, and the second extraction component 7 through the PLC control system 11, thereby achieving intelligent monitoring.

[0034] Secondly, refer to Figure 1In this embodiment, a water replenishment tank 8 is also installed on the left side of the monitoring box 1. The water replenishment tank 8 stores tap water, and a third extraction component 81 is installed on one side of the water replenishment tank 8. The input end of the third extraction component 81 is connected to the water outlet end of the water replenishment tank 8 through the water inlet pipe 82, and the output end of the third extraction component 81 is connected to the water inlet end of the top of the transparent negative pressure liquid storage cylinder 2 through the water replenishment pipe 83.

[0035] Specifically, the third extraction component 81 is also an extraction device combining a water pump and a motor; the inlet pipe 82 and the water supply pipe 83 both use DN20 pipes. At the same time, the third extraction component 81 is also electrically connected to the PLC control system 11 to facilitate the control of the third extraction component 81.

[0036] After sludge monitoring is completed, the water pump and motor are started, causing the inlet pipe 82 to draw tap water from the water supply tank 8. The tap water is then drawn into the transparent negative pressure storage cylinder 2 through the water supply pipe 83. Next, the second extraction component 7 is activated to draw the tap water from the transparent negative pressure storage cylinder 2 into the transparent measuring cylinder 3, thus completing the rinsing process of the transparent negative pressure storage cylinder 2 and the transparent measuring cylinder 3. After rinsing, the water is discharged into an external collection tank through the drain pipe 32, completing the rinsing process.

[0037] This structure, through the cooperation of the water replenishment tank 8, the third extraction component 81, the water inlet pipe 82, and the water replenishment pipe 83, can effectively rinse the transparent negative pressure liquid storage cylinder 2 and the transparent measuring cylinder 3, thereby maintaining the cleanliness of the transparent negative pressure liquid storage cylinder 2 and the transparent measuring cylinder 3, and ensuring that the accuracy of the next sampling observation is not affected by the previous sampling.

[0038] Preferably, in this embodiment, solenoid valves 9 and valves 10 are installed on the first suction pipe 61, the first delivery pipe 62, the second suction pipe 71, the second delivery pipe 72, the inlet pipe 82, the replenishment pipe 83, and the drain pipe 32. Through the coordinated arrangement of solenoid valves 9 and valves 10, not only can the opening and closing of the liquid in these pipes be controlled, but the flow rate of the liquid in these pipes can also be adjusted to meet the flow requirements under different working conditions. At the same time, the flow direction of the liquid can be changed as needed to achieve directional control of the liquid, thereby improving monitoring efficiency and safety.

[0039] The implementation principle of the sludge settling ratio automatic sampling and monitoring device in this application embodiment is as follows: When it is necessary to sample and observe the sludge mixture, the first extraction component 6 is activated first, and the sludge mixture in the sludge tank 4 is extracted and transported to the inside of the transparent negative pressure storage cylinder 2 through the first suction pipe 61 and the first water delivery pipe 62, so as to store the sludge mixture in the transparent negative pressure storage cylinder 2; then the second extraction component 7 is activated, and the sludge mixture stored in the transparent negative pressure storage cylinder 2 is extracted and transported to the inside of the transparent measuring cylinder 3 through the second suction pipe 71 and the second water delivery pipe 72.

[0040] Then, the liquid level controller 31 ensures that the liquid level in the transparent measuring cylinder 3 does not overflow and is controlled at the required height. The timer is set automatically for 30 minutes. After that, the network camera 5 takes pictures of the transparent measuring cylinder 3 and the sludge mixture inside the transparent measuring cylinder 3. The pictures are then fed back to the PLC control system 11. The software algorithm in the PLC control system 11 automatically determines whether the sludge is abnormal based on the pictures. If an abnormality is found, it can also determine what kind of abnormality it is. After the sampling and observation are completed, the water in the transparent measuring cylinder 3 is drained through the drain pipe 32, thus completing the sampling and observation process of the sludge mixture.
