Description

Technical Field

[0001] This utility model relates to the field of online cleaning technology for turbidity meters, and in particular to an online cleaning device for a high-density sedimentation tank turbidity meter. Background Technology

[0002] High-density sedimentation tanks are an advanced water treatment technology. They offer unparalleled advantages in the greywater reuse industry and play a crucial role in the zero-discharge field of coal chemical wastewater treatment. This technology can simultaneously remove hardness, suspended solids, colloids, and total phosphorus from water, ensuring comprehensive water purification. For these reasons, high-density sedimentation tanks have been widely and extensively applied in municipal and industrial wastewater treatment in my country, making significant contributions to water resource recycling and environmental protection.

[0003] In water quality monitoring within high-density sedimentation tanks, turbidity meters are crucial measuring instruments. However, due to the complex water quality in sedimentation tanks, turbidity meter probes are prone to contamination, affecting measurement accuracy and stability. Traditional cleaning methods typically require periodic manual disassembly and cleaning, which is cumbersome and inefficient, failing to meet the demands of continuous online monitoring. Therefore, we propose an online cleaning device for turbidity meters in high-density sedimentation tanks. Utility Model Content

[0033] Working principle:

[0034] In the first implementation case, during normal operation and measurement, that is, under the normal state of torsion spring 35, sealing plate 31 is away from through hole 5, making through hole 5 in a conductive state. Then, under the control of PLC, the electric telescopic rod 2 is started to drive turbidity meter 3 to fall into the sedimentation tank to measure the turbidity of the water sample in the sedimentation tank.

[0035] Implementation Case 2: Alkaline Cleaning. After a certain cycle of operation in Implementation Case 1, the turbidity meter 3 undergoes a cleaning procedure. Under the control of the PLC, the electric telescopic rod 2 retracts, moving the turbidity meter 3 into the cleaning tank 4. At this time, the alkaline control outlet solenoid valve 22 opens and the alkaline cleaning pump 21 starts. The clean water rinsing pump 17 and the acidic cleaning pump 19 do not start, and the clean water rinsing outlet solenoid valve 18 and the acidic control outlet solenoid valve 20 are closed. During this process, the alkaline cleaning pump 21 cleans the turbidity meter 3. The alkaline cleaning agent inside the washing tank 9 is transported to the cleaning tank 4 through the third delivery pipe 16 to rinse the turbidity meter 3. Furthermore, by controlling the rotation of the motor 27, the drive shaft 28 rotates, which in turn drives the first spur gear 29, which in turn drives the gear ring 30, which in turn drives the sleeve 24. This causes the brush 25 to clean the turbidity meter 3. During the rotation of the drive shaft 28, the second spur gear 38 rotates, driving the incomplete gear 39 to rotate, which in turn causes the rotating shaft 33 to rotate. The rotating shaft 33 drives the connecting block 32 and the sealing plate 31 to rotate, so that the sealing plate 31 rotates to correspond with the through hole 5 (during this process, the torsion spring 35 will be in a tightened state), so that the through hole 5 is closed, and the cleaning tank 4 is filled with alkaline drugs to clean the turbidity meter 3. During this process, the overflow solenoid valve 43 is opened. When the cleaning tank 4 is full of drugs, the drugs can be discharged through the overflow pipe 42. After this process lasts for 5 minutes, the alkaline cleaning pump 21 and the alkaline control outlet solenoid valve 22 are closed. Then, the clean water rinsing cleaning pump 17 and the clean water rinsing outlet solenoid valve 18 are opened. The clean water rinsing cleaning pump 17 transports the water in the clean water tank 40 to the cleaning tank 4 through the first delivery pipe 14. The turbidity meter 3 is cleaned by the action of the clean water. As shown above, the clean water rinsing process lasts for 5 minutes. After the alkaline rinsing is completed, the sealing plate 31 is reset by the action of the torsion spring 35. Then, the turbidity meter 3 measures the turbidity of the water sample in the sedimentation tank according to the operation of implementation case 1.

[0036] Implementation Case 3: Acid Cleaning. After a certain cycle of operation in Implementation Case 1, the turbidity meter 3 undergoes a cleaning procedure. Under the control of the PLC, the electric telescopic rod 2 retracts, moving the turbidity meter 3 into the cleaning tank 4. At this time, the acid control outlet solenoid valve 20 opens and the acid cleaning pump 19 starts, while the clean water rinsing pump 17 and the alkaline cleaning pump do not start. The clean water rinsing outlet solenoid valve 18 and the alkaline control outlet solenoid valve 22 are closed. During this process, the acid cleaning pump 19 pumps the acid cleaning solution from the cleaning tank... The pickling agent inside the 8 is delivered to the cleaning tank 4 through the second delivery pipe 15 to rinse the turbidimeter 3. Furthermore, by controlling the rotation of the motor 27, the drive shaft 28 rotates, which in turn drives the first spur gear 29, which in turn drives the gear ring 30, which in turn drives the sleeve 24. This causes the brush 25 to clean the turbidimeter 3. During the rotation of the drive shaft 28, the second spur gear 38 rotates, driving the incomplete gear 39, which in turn causes the rotating shaft 33 to rotate. Therefore, the rotating shaft 33 drives the connecting block 32 and the sealing plate 31 to rotate, so that the sealing plate 31 rotates to correspond with the through hole 5 (during this process, the torsion spring 35 will be in a tightened state), so that the through hole 5 is closed, and then the cleaning tank 4 is filled with alkaline drugs to clean the turbidity meter 3. During this process, the overflow solenoid valve 43 is opened. When the cleaning tank 4 is full of drugs, the drugs can be discharged through the overflow pipe 42. After this process lasts for 5 minutes, the acid cleaning pump 19 and the acid control outlet solenoid valve 20 are closed. Then, the clean water rinsing pump 17 and the clean water rinsing outlet solenoid valve 18 are opened. The clean water rinsing pump 17 transports the water in the clean water tank 40 to the cleaning tank 4 through the first delivery pipe 14. The turbidity meter 3 is cleaned once by the action of the clean water. As shown above, the clean water rinsing process lasts for 5 minutes. After the alkaline washing is completed, the sealing plate 31 is reset by the action of the torsion spring 35. Then, the turbidity meter 3 measures the turbidity of the water sample in the sedimentation tank according to the operation of implementation case one.

[0037] Implementation Case 4 involves acid-base mixed cleaning, which is carried out in sequence with Implementation Case 2 and Implementation Case 3. It is worth noting that during the mixed cleaning, after the acid washing, alkaline washing and rinsing with clean water are completed, the turbidity meter is once again inserted into the sedimentation tank to measure the turbidity of the water sample.

[0038] It should be noted that: Under normal conditions, the sealing plate 31 will move away from the through hole 5, thus opening the through hole 5. When sealing the through hole 5, i.e. during the cleaning process of the turbidity meter 3, the rotation of the second spur gear 38 will drive the rotation of the incomplete gear 39. After the sealing plate 31 seals the through hole 5, the second spur gear 38 will be in a state of dynamic equilibrium with the incomplete gear 39. That is, through the action of the torsion spring 35, the second spur gear 38 is just engaged with the last tooth of the incomplete gear 39. Therefore, the continuous rotation of the drive shaft 28 will not affect the position of the sealing plate 31. Thus, the through hole 5 is sealed during the cleaning process. After the cleaning is completed, the reset of the torsion spring 35 will cause the rotating shaft 33 to drive the connecting block 32 and the sealing plate 31 to reset away from the through hole 5, i.e., restore the normal state of the torsion spring 35, which will then facilitate the free extension and retraction of the turbidity meter 3.
