Description

Technical Field

[0001] The present invention relates to the field of sewage detection, and more specifically, to a sewage detector. Background Art

[0002] At present, sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. Before sewage treatment, it is necessary to detect the components of various substances in the sewage. In order to ensure the progress of sewage treatment, it is usually necessary to detect the sewage in the ditch to determine whether its various indicators meet the requirements. Since there are many detection indicators, people need to take samples of the sewage for testing to ensure that the right medicine is applied.

[0003] When the sewage detector in the prior art takes sewage samples, generally, a water pipe is driven to move downward in the sewage by a lifting device. When the water pipe descends to a certain position, water is taken by opening a valve, thus completing the sewage sampling. However, this kind of sewage detector is not convenient for stratified sampling of sewage at different depths during sampling, and it is easy for the samples to interfere with each other and affect the detection accuracy.

[0004] Chinese Patent with Application No. CN202311729745.7 discloses a sewage detection device, including: a sampling pipe, the upper and lower ends of the sampling pipe are both closed structures, and a plurality of sampling chambers are arranged inside the sampling pipe along its height direction. Adjacent sampling chambers are isolated by a sealing plate, and each sampling chamber is provided with a water inlet; a valve plate that can move up and down is connected to the water inlet. Among them, there is no valve plate at the water inlet of the first layer. The valve plate is used to close the water inlet, and a lifting seat that can be lifted and lowered is connected inside the sampling chamber. The lifting seat is sealed with the inner wall of the sampling pipe, and the lifting seat is arranged below the water inlet; a connecting rod is fixedly connected to the lower surface of the lifting seat, the connecting rod extends into the adjacent lower sampling chamber, and the lower end of the connecting rod is connected to the valve plate in the adjacent lower sampling chamber; this invention achieves the purpose of stratified sampling by arranging multiple layers of sampling chambers in the sampling pipe to take water from sewage at different depths in sequence. However, this invention still has problems such as being prone to incorporating impurities during sewage detection sampling and interference between samples during multiple samplings.

[0033] Embodiment 1

[0034] During the actual production process, due to the need for multiple samplings during detection, the residual samples in the sampling chamber will interfere with each other, easily causing a large detection error and reducing the detection accuracy. To solve the above problems, this embodiment is specifically invented.

[0035] Please refer to Figure 1 and Figure 2 As shown, a sewage detector according to an embodiment of the present invention includes a support frame 1.

A sewage discharge hole 631 is provided in the inner cavity of the sewage discharge cavity 63. A second water outlet 64 is provided at the lower part of the sewage discharge cavity 63. A second motor 46 is fixedly connected to the bottom of the sewage discharge cavity 63. The output end of the second motor 46 is fixedly connected to a second gear 45. The second gear 45 meshes with a third gear 44. The third gear 44 is fixedly connected to the top of the sample retention mechanism 4.

[0039] Please refer to Figure 1 and Figure 2 As shown in the figure, the support frame 1 includes a fixed plate 12. A third motor 13 is fixedly installed at the upper end of the fixed plate 12. The output end of the third motor 13 is fixedly connected to a coupling 14. Two first lead screws 15 are rotatably connected inside the fixed plate 12. Both of the two first lead screws 15 are in transmission connection with the coupling 14 through a transmission mechanism. One end of the first lead screw 15 away from the fixed plate 12 is threadedly connected to a lifting plate 11. Four guide rails 16 are evenly and fixedly connected to the fixed plate 12. One end of each guide rail 16 away from the fixed plate 12 is slidably connected to the lifting plate 11.

[0040] Please refer to Figure 2 and Figure 7 As shown in the figure, a filter chamber 2 is fixedly connected to the lower part of the sample retention chamber 41. A filter port 21 is provided on the outer wall of the filter chamber 2. A first motor 22 is fixedly connected to the outer wall of the filter port 21. The output end of the first motor 22 is fixedly connected to a driving wheel 23. A transmission member 24 is engaged with the outer surface of the driving wheel 23. A plurality of filter plates 26 are rotatably connected to the inner wall of the filter port 21. One end of each filter plate 26 is fixedly connected to a driven wheel 25. Each driven wheel 25 and the driving wheel 23 are in transmission connection through the transmission member 24. A filter screen 27 is fixedly connected to the inner cavity of the filter port 21.

[0041] Please refer to Figure 2 As shown in the figure, a fourth motor 111 is fixedly connected to the lifting plate 11. The output end of the fourth motor 111 is fixedly connected to a second lead screw 112. One end of the second lead screw 112 away from the lifting plate 11 is rotatably connected to the bottom surface of the filter chamber 2. The inner wall of the sampling chamber 3 is rotatably connected to the second lead screw 112. The outer wall of the sampling chamber 3 is slidably connected to the filter chamber 2, the sample retention mechanism 4 and the cleaning chamber 6.

[0042] During use, first start the third motor 13 to reverse the third motor 13. The third motor 13 drives the first lead screw 15 to rotate through the coupling 14, thereby causing the lifting plate 11 to descend. The coupling 14 is an existing technology and will not be elaborated here.

[0043] When the lifting plate 11 descends to the specified water area, start the fourth motor 111, reverse the fourth motor 111 to drive the second lead screw 112 to rotate. While the second lead screw 112 rotates, lower the sampling chamber 3 into the filtration chamber 2. When the sampling port 31 at the lower end of the sampling chamber 3 coincides with the filtration port 21 on the outer wall of the filtration chamber 2, the first elastic member 34 expands and pushes the rack 33 to slide inside the sampling port 31. At the same time, the sleeve 32 slides on the outer wall of the sampling port 31, driving the sealing plate 35 to rotate, and the sampling port 31 is opened.

[0044] When the sampling chamber 3 descends to the specified position, start the first motor 22. The first motor 22 rotates reciprocally. The first motor 22 drives the driven wheel 25 to rotate reciprocally through the transmission member 24. The driven wheel 25 drives the filter plate 26 to rotate reciprocally, pushing aside larger impurities in the sewage to prevent the filtration port 21 from being blocked. The sewage passes through the filter plate 26 and is filtered by the filter net 27 to remove other impurities in the sewage, and enters the sampling port 31 through the filtration port 21 and then flows into the sampling chamber 3.

[0045] After sampling is completed, turn off the first motor 22, the filter plate 26 closes, and the sewage no longer enters the filtration port 21. At the same time, reverse the fourth motor 111 to raise the sampling chamber 3. When the sampling chamber 3 rises, the sleeve 32 is squeezed, pushing the rack 33 to slide inside the sampling port 31. Through the sliding of the rack 33, the sealing plate 35 is driven to rotate. At the same time, the first elastic member 34 is compressed, and the sampling port 31 is closed to prevent the sample from flowing out to the inner wall of the instrument during the rising process, resulting in interference between samples during multiple samplings.

[0046] When the sampling chamber 3 rises until the sampling port 31 coincides with the first water inlet 42 of the sample storage chamber 41, the first elastic member 34 expands again, the sleeve 32 meshes with the first water inlet 42, and the sampling port 31 is opened again. The sample flows into the sample storage chamber 41 through the sampling port 31 and the first water inlet 42. When enough samples flow into the sample storage chamber 41, the sampling chamber 3 continues to rise. When the sampling port 31 coincides with the sewage discharge hole 631, at this time, the valve plate 621 is pressed by the bottom of the sampling chamber 3, and the washing water inside the washing chamber 61 sprays out from the nozzle 62. At the same time, the sewage for cleaning the sampling chamber 3 enters the sewage discharge chamber 63 through the sewage discharge hole 631.

[0047] After the cleaning is completed, the position of the lifting plate 11 is adjusted by the forward rotation of the third motor 13, so as to adjust the sampling water area. When the designated water area is reached, the fourth motor 111 is reversed, and at the same time, the second motor 46 is started. The second motor 46 drives the second gear 45 to rotate, drives the third gear 44 to rotate through the second gear 45, and the third gear 44 drives the sample storage chamber 41 to rotate, so that the first water inlet 42 in the unused sample storage chamber 41 rotates to a position perpendicular to the sampling port 31, so as to perform re-sampling, so as to prevent sample interference caused by sample residue inside the sampling chamber 3 when sampling multiple times at different depths and different water areas. After all sampling is completed, the first water outlet 43 is opened to take out the sample in the sample storage chamber 41, and the second water outlet hole is opened to drain the sewage in the sewage discharge chamber 63.

[0048] Embodiment 2

[0049] It is found in actual use that samples usually need to be detected separately for water body and suspended matter during detection. Since the efficiency of separating suspended matter after taking out the water body sample first is relatively low, further improvements are made on the basis of the above embodiments.

[0050] Please refer to Figure 2 and Figure 5 As shown, a separation chamber 5 is fixedly connected to the lower end of each sample storage chamber 41. A baffle 51 is slidably connected to the inner top surface of each separation chamber 5. One end of each baffle 51 is rotatably connected to a connecting rod 52. The end of each connecting rod 52 far from the baffle 51 is rotatably connected to a base 53. A connecting column 56 is fixedly connected to the inner bottom surface of each separation chamber 5. A second elastic member 54 is sleeved on the outer wall of each connecting column 56. The two ends of each second elastic member 54 are respectively connected to the bottom of the base 53 and the inner bottom surface of the separation chamber 5. Each connecting column 56 is slidably connected to the bottom of the base 53. A separation bottle 511 is arranged on each base 53. Each separation bottle 511 is embedded in the inner bottom of the corresponding base 53. A filter membrane 512 is arranged at the mouth of each separation bottle 511. A funnel 513 is arranged above each filter membrane 512. Each funnel 513 is embedded at the mouth of the corresponding separation bottle 511.

[0051] On the basis of the above embodiments, during use, when the sample enters the sample storage chamber 41, part of the sample flows into the funnel 513 inside the separation chamber 5 through the second water inlet 514. After the suspended matter is separated by the filter membrane 512, at this time, the suspended matter in the sample remains on the filter membrane 512, and the water body sample flows into the separation bottle 511. As the sample flows into the funnel 513 and the separation bottle 511, under the action of gravity, the base 53 slides on the outer wall of the connecting column 56, and the second elastic member 54 is compressed. At the same time, the connecting rod 52 rotates, driving the baffle 51 to slide inside the separation chamber 5. When there is enough sample, the second water inlet 514 is blocked by the baffle 51, and the sample no longer flows into the separation chamber 5.

[0052] After all the sampling is completed, rotate the partition plate 55, take out the separation bottle 511, the funnel 513 and the filter membrane 512, so that the staff can separate and sample the water body and the suspended matter while sampling, improving the work efficiency.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
