Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to an automatic sewage detection device and system. Background Art

[0002] Currently, in sewage treatment, in order to avoid water resource pollution, it is necessary to treat sewage. At the same time, after treatment, it is necessary to detect the treated sewage to judge the sewage treatment effect. The traditional detection method is to manually go to the sewage pool to take samples and then put them into the sewage detection device for water quality detection. However, the method of manually collecting samples has low efficiency.

[0003] In the prior art, a water pump is used to pump out the water in the sewage pool for sampling and then perform liquid level detection, replacing manual operation and greatly improving the sampling efficiency.

[0004] However, in the aforementioned prior art, in order to ensure the accuracy of the results, it is necessary to take samples from multiple areas or multiple depths of the sewage pool. At the same time, after the water in the sewage pool is replaced, the water quality will also change. Therefore, it is usually necessary to take samples repeatedly. When pumping water, usually only one water pipe is used, and the water pipe is not easy to disassemble and clean, resulting in the residue of the previous sewage, ultimately affecting the sampling accuracy.

[0025] Among them, the box body 1 has a first storage body 6 and a second storage body 7. The first water pump 2 is arranged inside the first storage body 6. The water suction pipe 3 and the drain pipe 4 are both connected to the first water pump 2. The first cylinder 5 is arranged outside the box body 1, and the output end of the first cylinder 5 is arranged on the water suction pipe 3. The detection unit is arranged on the drain pipe 4. The negative pressure pump 8 is arranged inside the box body 1. The cleaning spray head 9 is arranged below the water suction pipe 3. The water suction pipe 3 is a telescopic hose. When the first cylinder 5 is started, it drives the water suction pipe 3 to move down into the sewage pool. Then the first water pump 2 is started, and sewage is pumped into the drain pipe 4 through the water suction pipe 3. At this time, the detection unit is started to detect the sewage in the drain pipe 4. After the detection is completed, the sewage is discharged. Then the cleaning spray head 9 is started to spray the cleaning agent and clean water into the drain pipe 4 from the water suction pipe 3 and spray out from the drain pipe 4 for cleaning. Then the negative pressure pump 8 is docked with the drain pipe 4, and the residual water inside the pipe is sucked away by negative pressure, further ensuring the accuracy of subsequent sewage detection. Therefore, there is no need to disassemble and replace the water suction pipe 3. Just spray the cleaning agent and clean water for cleaning and suck away the residual water after cleaning, so as to achieve the purpose of cleaning the water suction pipe 3 and the drain pipe 4, avoid the mutual influence of residual sewage, and improve the accuracy of sewage detection and sampling.

[0026] Secondly, the cleaning box body 10 and the collection box body 12 are sequentially arranged inside the second storage body 7. Both of the two water adding pipes 11 are communicated with the cleaning box body 10. The sewage discharge pipe 13 is communicated with the collection box body 12. The maintenance door panel 14 is rotatably connected to the box body 1. The water storage unit is arranged on the cleaning box body 10. The cleaning box body 10 can be used to store the cleaning agent and clean water. The maintenance door panel 14 is convenient for opening the box body 1, and then the cleaning agent and clean water can be added respectively through the water adding pipes 11. The collection box body 12 is used to collect the waste liquid generated by cleaning and the sewage after detection. The sewage discharge pipe 13 is used to discharge the liquid inside the collection box body 12. The water outlet unit is used to pump out the cleaning agent and clean water inside the cleaning box body 10 and spray them into the water suction pipe 3.

[0027] Meanwhile, the partition plate 15 is arranged inside the cleaning box body 10. One ends of the two water outlet pipes 16 are both communicated with the cleaning box body 10 and symmetrically distributed on both sides of the partition plate 15. The other ends of the two water outlet pipes 16 are both communicated with the second water pump 18. The two first valves 17 are respectively arranged on the corresponding water outlet pipes 16. The water outlet end of the second water pump 18 is communicated with the water outlet groove 19. The second air cylinder 20 is arranged on one side of the cleaning box body 10. The output end of the second air cylinder 20 is fixedly connected with the connecting plate 21. The connecting plate 21 is arranged on the water outlet groove 19. The partition plate 15 divides the cleaning box body 10 into two storage areas, which are respectively used for storing cleaning agents and clean water. When water outlet cleaning is required, the second air cylinder 20 is started to drive the connecting plate 21 to move, driving the water outlet groove 19 to move out of the second bin body 7. At this time, the first air cylinder 5 is started to drive the water inlet groove 27 to move down for docking. The second water pump 18 is started, and at the same time, the first valve body on the water outlet pipe 16 is opened. First, the cleaning agent is pumped out for pipeline cleaning, and then the other water outlet pipe 16 is opened to flush with clean water to clean the residual cleaning agent.

[0028] In addition, the two second valve bodies are sequentially arranged on the drain pipe 4. The pH sensor 23, the ammonia nitrogen sensor 24, the dissolved oxygen sensor 25 and the residual chlorine sensor 26 are sequentially arranged on the drain pipe 4. When extracting a sewage sample, first close the second valve body far away from the first water pump 2. After the sewage enters the drain pipe 4, then close the other second valve body, thereby restricting the sewage sample between the two second valve bodies. At this time, start the pH sensor 23, the ammonia nitrogen sensor 24, the dissolved oxygen sensor 25 and the residual chlorine sensor 26 to detect the sewage and judge whether the sewage treatment is qualified. After the detection is completed, open the two second valve bodies, and the sewage flows into the collection box body 12.

[0029] Then, the docking unit includes a water inlet groove 27 and a water inlet sealing ring 28. The water inlet groove 27 is communicated with one end of the water extraction pipe 3. The water inlet sealing ring 28 is arranged on the water inlet groove 27. The cleaning spray head 9 is arranged on the water outlet groove 19. The water inlet sealing ring 28 and the cleaning spray head 9 are mutually adapted. When performing water outlet cleaning, the cleaning agent or clean water can reach the water extraction pipe 3 through the water inlet groove 27. When the water inlet groove 27 and the water outlet groove 19 are docked, the water inlet sealing ring 28 and the cleaning spray head 9 can be sealed to avoid water seepage and leakage.

[0030] Finally, the adjusting unit is arranged inside the box body 1; the third cylinder 30 is arranged on the electric slide rail 29, the output end of the third cylinder 30 is fixedly connected to the negative pressure pump 8, the air inlet end of the negative pressure pump 8 is provided with the sealing ring body 31, the air outlet end of the negative pressure pump 8 is adapted to the slot 32, and the sealing ring body 31 is adapted to one end of the drain pipe 4. When the third cylinder 30 is started, the height of the negative pressure pump 8 is adjusted, then the electric slide rail 29 is started to drive the third cylinder 30 to approach the drain pipe 4, and it is docked through the sealing ring body 31 to avoid water seepage and leakage. At this time, when the negative pressure pump 8 is started, the residual water in the pipeline can be sucked away, further improving the detection accuracy.

[0031] When using the automatic sewage detection device of this embodiment, the first cylinder 5 is started to drive the water extraction pipe 3 to move down into the sewage tank. The first water pump 2 is started, and sewage is pumped into the drain pipe 4 through the water extraction pipe 3. At this time, the PH sensor 23, the ammonia nitrogen sensor 24, the dissolved oxygen sensor 25 and the residual chlorine sensor 26 are started to detect the sewage to judge whether the sewage treatment is qualified. After the detection is completed, two second valve bodies are opened, and the sewage flows into the collection box body 12. At this time, the second cylinder 20 is started to drive the connecting plate 21 to move, driving the water outlet groove 19 out of the second chamber 7. At this time, the first cylinder 5 is started to drive the water inlet groove 27 to move down, so that the water inlet sealing ring 28 is docked with the cleaning spray head 9. The second water pump 18 is started, and at the same time, the first valve body on the water outlet pipe 16 is opened. First, the cleaning agent is pumped out for pipeline cleaning, and then another water outlet pipe 16 is opened to flush with clean water to wash away the residual cleaning agent; the third cylinder 30 is started to adjust the height of the negative pressure pump 8, then the electric slide rail 29 is started to drive the third cylinder 30 to approach the drain pipe 4, and it is docked through the sealing ring body 31 to avoid water seepage and leakage. At this time, when the negative pressure pump 8 is started, the residual water in the pipeline can be sucked away, further improving the detection accuracy. Through the above structural settings, there is no need to disassemble and replace the water extraction pipe 3. Only the cleaning agent and clean water need to be sprayed for cleaning, and the residual water after cleaning is sucked away, so as to achieve the purpose of cleaning the water extraction pipe 3 and the drain pipe 4, avoiding the mutual influence of residual sewage, and improving the accuracy of sewage detection and sampling.

[0033] Among them, the sewage tank water level control device 33 first controls the water level in the sewage tank, so that the downwardly moving water inlet tank 27 can contact the sewage. At the same time, after the detection is qualified, the water in the sewage tank is discharged, and a new round of sewage to be detected is put in. After the detection is completed, the sewage detection and reflux device 34 collects and treats the sewage generated by cleaning and the sampled sewage, and then returns it to the sewage tank. When the sewage anomaly alarm device 35 detects unqualified sewage, it issues an alarm to remind the staff.
