Detailed Implementation
[0024] Municipal wastewater treatment sampling devices are used to collect wastewater samples periodically or continuously for monitoring and analysis of the wastewater treatment process. By testing the samples, the effectiveness of wastewater treatment can be evaluated to ensure compliance with discharge standards. Generally, sampling devices are mainly used to test water quality parameters such as pH value, chemical oxygen demand (COD), biochemical oxygen demand (BOD), suspended solids (SS), nitrogen, and phosphorus.
[0025] Municipal wastewater treatment sampling devices typically come in the following types:
[0026] 1. Automatic sampler
[0027] Automatic samplers can automatically extract samples from pipes or sewage tanks at specified time intervals. Depending on the set time or flow rate, they can periodically collect sewage samples at different times or flow rates, making them suitable for scenarios requiring continuous monitoring. Time-based automatic samplers automatically sample at predetermined time intervals (e.g., every hour or every day).
[0028] Flow-type automatic sampler: Automatically samples wastewater based on changes in flow rate. For example, the sampling frequency is increased when the flow rate is high.
[0029] 2. Manual sampling device
[0030] Manual sampling devices are typically operated by personnel on-site to collect samples directly from sewage tanks, pipes, or other discharge points. While this method is suitable for small-scale monitoring, it is highly susceptible to human factors due to the need for manual operation and is therefore only suitable for scenarios where sampling frequency requirements are not high.
[0031] 3. Multi-point sampling device
[0032] In municipal wastewater treatment plants, wastewater flows through multiple process sections or different locations, which may require sampling at multiple points. Multi-point sampling devices typically include multiple sampling points and can collect samples at different locations simultaneously. This method is suitable for situations where multiple stages or multiple pipelines need to be monitored during the treatment process.
[0033] 4. Flow weighted sampling device
[0034] This device takes into account the wastewater flow rate during sampling and ensures the representativeness of the samples through weighting. For example, when the flow rate is high, the device may collect more water samples to reflect the relationship between wastewater flow rate and water quality.
[0035] Key technical requirements for sampling devices:
[0036] Accuracy and stability: The sampling device needs to ensure that the collected samples can accurately reflect the water quality of the wastewater. Corrosion resistance: Since wastewater may contain corrosive substances, the sampling device needs to have strong corrosion resistance. Common materials include stainless steel, plastic, and glass. Ease of cleaning: In order to avoid cross-contamination of samples and equipment failure, the sampling device needs to be reasonably designed and easy to clean. Automation and data transmission functions: Modern automatic sampling devices are usually equipped with data recording and transmission systems, which can upload sampling data to the monitoring system in real time or periodically, facilitating remote monitoring and management.
[0037] Sampling devices in municipal wastewater treatment not only help understand changes in wastewater quality but also provide a basis for further water treatment optimization. At the same time, these devices play a crucial role in environmental monitoring and wastewater discharge compliance checks.
[0038] Please see Figures 1-7This utility model provides an embodiment of a municipal sewage treatment sampling device, including a first frame 1, a second frame 3, a third frame 6, a pulley 5, a wire rope 4, and a sampling bottle 8. It also includes a threaded bolt 2, an upper clamping block 15, a sliding cylinder 19, and a bearing 21. The first frame 1 has threaded grooves 9 extending through its upper and lower ends, with a threaded bolt 2 installed in each groove. An annular block 18 is fixedly connected to the lower end of the threaded bolt 2. An annular sleeve 16 is provided at the upper end of the upper clamping block 15, and the annular block 18 is installed within the annular sleeve 16. A limit frame 17 is fixedly connected to the rear end of the upper clamping block 15. First grooves are extending through the left and right edges of the first frame 1. 11. A second groove 12 is provided through the inner wall of the front end of the first groove 11. The outer wall of the limiting frame 17 is adapted to the inner wall of the second groove 12. The first groove 11 is adapted to the limiting frame 17. A second frame 3 is fixedly connected to the lower end of the first frame 1. A lower clamping block 10 is fixedly connected to the upper end of the second frame 3. A third frame 6 is fixedly connected to the lower edge of the second frame 3. A third groove 13 is provided through the upper and lower ends of the third frame 6. A bearing 21 is installed in the third groove 13. A support frame 20 is fixedly connected to the lower edge of the third frame 6. A sliding cylinder 19 is installed on the support frame 20. A steel wire rope 4 passes through the bearing 21 and the sliding cylinder 19.
[0039] The sliding cylinder 19 with internal ball bearings and bearing 21 can assist the wire rope 4 in multiple limit adjustments during rotation and winding to prevent it from tangling or knotting during use, thus affecting its normal use. By rotating the threaded bolt 2, the upper clamping block 15 can be pushed closer to the lower clamping block 10 to clamp and fix the first frame 1 to the inner wall of the municipal sewage well. The limiting frame 17 can help the upper clamping block 15 maintain good stability during displacement adjustment, thereby improving the stability of the upper clamping block 15 and the lower clamping block 10 clamping and fixing to the inner wall of the municipal sewage well. The annular sleeve 16 can maintain the connection between the threaded bolt 2 and the upper clamping block 15 while also allowing the threaded bolt 2 to rotate and push the upper clamping block 15.
[0040] Please see Figures 3-5In this embodiment, a pulley 5 is rotatably installed inside the first frame 1, and a steel wire rope 4 is wound around the pulley 5. In use, the pulley 5 can drive the steel wire rope 4 to drive the sampling bottle 8 to flexibly adjust its height, so that the user can adjust the sampling bottle 8 in the sewage well. A drive motor 7 is installed at the right end of the first frame 1. The output end of the drive motor 7 passes through the rear end of the first frame 1 and is connected to the pulley 5. In use, the drive motor 7 can lower the sampling bottle 8 when needed and let it enter the sewage for sampling. Anti-slip textures are provided on the upper clamping block 15 and the lower clamping block 10. A storage battery is installed inside the third frame 6. In use, the anti-slip textures on the upper clamping block 15 and the lower clamping block 10 can greatly improve the stability and firmness of the upper clamping block 15 and the lower clamping block 10 clamping and fixing to the inner wall of the sewage well.
[0041] Please see Figures 3-7 In this embodiment, a triangular knot 14 is installed at the lower end of the wire rope 4, and a sampling bottle 8 is hung at the lower end of the triangular knot 14. During use, the triangular knot 14 can maintain the stability of the sampling bottle 8 to a certain extent. The centers of the sliding cylinder 19 and the bearing 21 are on the same vertical horizontal line. The upper clamping block 15 and the lower clamping block 10 correspond one-to-one. During use, the sliding cylinder 19 and the bearing 21, whose centers are on the same vertical horizontal line, can keep the wire rope 4 in a vertical state for lifting and lowering adjustment. The sliding cylinder 19 is provided with movable balls. The upper outer wall of the threaded bolt 2 is provided with a rotating handle that is equidistantly distributed around the threaded bolt 2. During use, the rotating handle can help the user to turn the threaded bolt 2 to bring the upper clamping block 15 and the lower clamping block 10 closer to each other.
[0042] In use, the first frame 1 is placed on the frame on the inner wall of the municipal sewage well, and the lower clamping block 10 is made to fit against the lower end of the frame inside the sewage well. Then, the threaded bolt 2 is turned so that the threaded bolt 2 rotates downward along the inner wall of the threaded groove 9 to push the upper clamping block 15 closer to the lower clamping block 10 and clamp and fix the frame inside the sewage well, so as to install the first frame 1, the second frame 3 and the third frame 6 in the sewage well.
[0043] Next, the battery inside the third frame 6 can provide power to the drive motor 7, and then the drive motor 7 is started. The drive motor 7 drives the pulley 5 to rotate, so as to release the wire rope 4, and then the sampling bottle 8 is submerged in the sewage to sample the sewage.
[0044] Then, start the drive motor 7, which drives the wire rope 4 to wind up the sampling bottle 8 to the lower end of the pulley 5. After sampling, the sampling bottle 8 is removed from the triangular knot 14 and stored.
[0045] Through the above steps, the sliding cylinder 19 with ball bearings and bearing 21 can assist the wire rope 4 in multiple limit adjustments during rotation and winding to prevent it from tangling or knotting during use, thus affecting its normal use. By rotating the threaded bolt 2, the upper clamping block 15 can be pushed closer to the lower clamping block 10 to clamp and fix the first frame 1 to the inner wall of the municipal sewage well. The limiting frame 17 can help the upper clamping block 15 maintain good stability during displacement adjustment, thereby improving the stability of the upper clamping block 15 and the lower clamping block 10 clamping and fixing to the inner wall of the municipal sewage well. The annular sleeve 16 can maintain the connection between the threaded bolt 2 and the upper clamping block 15 while allowing the threaded bolt 2 to rotate and push the upper clamping block 15. This solves the problems of existing municipal sewage treatment sampling devices being inconvenient to carry and install, and the ropes being easy to tangle or knot.
