Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to an online sewage sampling device for influent water. Background Technique

[0002] The process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. It has also increasingly entered the daily lives of ordinary people. To ensure the sewage treatment effect, before the sewage enters the sewage treatment plant, it is necessary to detect the sewage to ensure that the sewage meets the standards for entering the sewage treatment plant for treatment, and to promptly block some sewage containing special components or not meeting the requirements for entering the sewage treatment plant.

[0003] Since the demand for sewage volume in sewage sampling and detection is small, the inner diameter of the sampling pipe is selected to be small, and the influent sewage has not been filtered. There are a large amount of sediment and debris in the sewage, which not only easily causes blockage of the sampling device and requires frequent replacement or dredging of the sampling bottle, but also the debris in the sampled sewage will affect the smooth progress of the detection task. Content of the Utility Model

[0024] An in-line sewage sampling device for water inlet, as Figures 1-4As shown in the figure, it includes a support frame 2 and a sampling bottle 4. One end inside the sampling bottle 4 is movably installed with a presser 13, and guide grooves 12 matching the presser 13 are provided at both ends of the sampling bottle 4. One end of the presser 13 is movably installed with a sampling inner liner 21, and a first spring 18 is installed between the presser 13 and the sampling inner liner 21. One end of the sampling inner liner 21 is fixedly installed with a filter plate 16, and one end of the sampling inner liner 21 is fixedly installed with a second limit plug 22. One end of the sampling bottle 4 is fixedly installed with a threaded rod 15, and a scraping plate 17 is movably installed at one end of the threaded rod 15. A second spring 19 is sleeved on one end of the threaded rod 15. Under the action of the first spring 18 and the second spring 19, the sampling inner liner 21 and the presser 13 start to reset. The first limit plug 8 releases the limit on the connecting pipe 3 while the second limit plug 22 starts to limit the sampling inner liner 21. Under the action of the external atmospheric pressure on the sampling bottle 4, the water sample is sucked into the sampling bottle 4 through the connecting pipe 3. At the same time, during the reset process of the sampling inner liner 21, the filter plate 16 starts to filter the sand and dust impurities in the water sample, and the scraping plate 17 rotates under the action of the threaded rod 15. The presser 13 starts to release the limit on the dust removal groove 20, so that the impurities and sediment attached to the surface of the filter plate 16 are scraped off by the scraping plate 17 and thrown into the dust collection box 9 through the dust removal groove 20 under the centrifugal action for unified collection.

[0025] Please refer to the figure. One end of the sampling bottle 4 is fixedly installed with a dust collection box 9, and the other end of the dust collection box 9 is fixedly installed with a discharge port 10. One end of the discharge port 10 is movably installed with an on-off valve 11. The first spring 18 and the second spring 19 are in a compressed state. By installing the first spring 18 and the second spring 19, the impact and vibration of the internal components of the device can be effectively absorbed and reduced, the components connected thereto can be protected, and the noise and wear can be reduced. At the same time, when a certain elastic restoring force is required for the presser 13 and the sampling inner liner 21, the normal operation and stability of the components can be ensured.

[0026] Please refer to Figure 3 , a dust removal groove 20 is provided on one side of the sampling inner liner 21, and a through hole 14 matching the discharge port 10 is provided at one end of the sampling inner liner 21. By providing the dust removal groove 20, when the scraping plate 17 rotates under the action of the threaded rod 15 and the presser 13 releases the limit on the dust removal groove 20, the impurities and sediment attached to the surface of the filter plate 16 are scraped off by the scraping plate 17 and thrown into the dust collection box 9 through the dust removal groove 20 under the centrifugal action to complete the collection operation of the impurities and sediment, thus avoiding a large amount of sediment impurities from accumulating in the sampling bottle 4 and facilitating the staff to clean the device.

[0027] Please refer to Figure 1 , one end of the support frame 2 is movably installed with a pipe placing disc 1, and a drawing port 6 is provided at one end of the pipe placing disc 1. A rotating handle 5 is fixedly installed at one end of the pipe placing disc 1. One end of the support frame 2 is fixedly installed with a clamp 7. By installing the support frame 2, the device can obtain better support force and is more stable during the operation and use of the device.

[0028] Please refer to Figure 2 , a connecting pipe 3 is connected between the pipe laying tray 1 and the sampling bottle 4, and a first limit plug 8 is fixedly installed at one end of the connecting pipe 3. By installing the first limit plug 8 and through the limiting effect of the first limit plug 8 on the connecting pipe 3, the water intake amount of the sampling bottle 4 each time the presser 13 is pressed can be restricted, meeting different sampling requirements.

[0029] The working principle of the present utility model is as follows: When in use, first, the extraction port 6 is released to the required sampling area by rotating the handle 5. Then, the presser 13 is pressed by the palm, causing the presser 13 to move vertically downward along the guiding groove 12 and compress the first spring 18. When the first spring 18 is compressed to a certain extent, it starts to press the sampling inner bladder 21 to move vertically downward along the threaded rod 15, compressing the second spring 19. At the same time, the presser 13 limits the dust removal groove 20 opened on the sampling inner bladder 21, and the first limit plug 8 starts to limit the connecting pipe 3 while the second limit plug 22 releases the limit on the sampling inner bladder 21, enabling the water sample in the sampling bottle 4 to enter the sampling inner bladder 21. Meanwhile, the space of the sampling bottle 4 shrinks. After stopping pressing the presser 13, under the action of the first spring 18 and the second spring 19, the sampling inner bladder 21 and the presser 13 start to reset. The first limit plug 8 releases the limit on the connecting pipe 3 while the second limit plug 22 starts to limit the sampling inner bladder 21, causing the water sample to be sucked into the sampling bottle 4 under the action of the external atmospheric pressure through the connecting pipe 3. Meanwhile, during the reset process of the sampling inner bladder 21, the filter plate 16 starts to filter the dust and impurities in the water sample, and the scraper 17 rotates under the action of the threaded rod 15. The presser 13 starts to release the limit on the dust removal groove 20, causing the impurities and sediment attached to the surface of the filter plate 16 to be scraped off by the scraper 17 and thrown into the dust collection box 9 through the dust removal groove 20 under the centrifugal action for unified collection. Finally, by rotating and opening the on-off valve 11, the water sample filtered by the sampling inner bladder 21 to remove impurities and sediment is discharged from the discharge port 10 through the through hole 14, and that's it.
