Description

Technical Field

[0001] This utility model relates to a sewage sample supply device and belongs to the field of sewage treatment sampling technology. Background Technology

[0002] As environmental protection departments impose increasingly stringent requirements on water quality indicators for urban wastewater treatment plants, these plants are now equipped with online wastewater monitoring systems. These systems collect wastewater data using samplers, ensuring real-time monitoring of the plant's water quality while simultaneously uploading the data to national and provincial environmental protection platforms. The sampling phase is crucial for ensuring the proper functioning of these online monitoring systems.

[0003] Because the influent water quality of the sewage treatment plant is poor, the sewage contains a large amount of sludge, hair and oily impurities, which can cause blockage of the sampling system. The sampler cannot obtain a water sample, and the online monitoring equipment has no water sample to measure, resulting in constant or abnormal measurement values. Utility Model Content

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the specific embodiments will be clearly and completely described below in conjunction with the accompanying drawings.

[0014] The wastewater sample supply device includes a sample supply tank 30 located at the front end of a first water pipe 21. The sample supply tank 30 has an inlet end 28 and an outlet end 27. The tank contains a wastewater sample 31 to be tested. A sampler 1 is connected to the sample supply tank 30 via the first water pipe 21 connected to the outlet end 27 of the sample supply tank 30. During operation, the sampler 1 can extract the wastewater sample 31 to be tested from the sample supply tank 30 for testing.

[0015] The inlet 28 of the water sample supply tank 30 is connected to the sampling pump 40 through the second water pipe 22. During operation, the sampling pump 40 draws sewage and sends it into the water sample supply tank 30 through the second water pipe 22.

[0016] The sampling pump 40 is a high-power submersible pump with a reamer impeller. A removable third external filter screen is installed at the sampling pump outlet 41. If the sampling volume decreases during operation, the removable filter screen can be removed, cleaned, and then reinstalled for continued use.

[0017] The water sample supply tank 30 is equipped with a level gauge 34 and a stirrer 35. The level gauge 34 is fixedly connected to the inner wall of the water sample supply tank 30. The stirrer 35 is controlled by the main control box 38 and is fixed at a position slightly above the bottom of the water sample supply tank 30, but below the effective liquid level. During operation, the stirrer 35 is activated as needed. For example, if the water sample to be tested in the water sample supply tank 30 is left to stand for a long time, causing the water sample to separate into layers, the concentration of the collected mixed sample may be insufficient, affecting the actual measurement results.

[0018] The water sample supply tank 30 is equipped with a main control box 38, a linkage level gauge 34, and a sampling pump 40. During operation, the main control box 38, through linkage, enables the sampling pump 40 to start water intake or open the drain outlet to drain water according to the liquid level in the water sample supply tank 30.

[0019] The main control box 38 controls the pumping frequency and time by controlling the timer 43, which is electrically connected to the sampling pump 40, to achieve timed operation of the sampling pump 40. The pumping time period of the sampling pump 40 can be set arbitrarily.

[0020] Preferably, the water sample supply tank is made of stainless steel, forming a stainless steel main body. This method is cost-effective, easy to manufacture, easy to clean, and durable in actual production and use.

[0021] The water sample supply tank 30 is equipped with a drain outlet 36 and an overflow outlet 37. The drain outlet 36 is located at the bottom of the water sample supply tank 30, and the overflow outlet 37 is located on the upper part of the side wall of the water sample supply tank 30. During operation, the wastewater 31 to be tested after sampling is discharged through the drain outlet. If the water sample tank is too full, it can be discharged through the overflow outlet 37.

[0022] A second temperature sensor 24 and a second heating device 26 are installed on the second water pipe 22 connecting the sampling pump 40 and the water sample supply tank 30; a first temperature sensor 23 and a first heating device 25 are installed on the first water pipe 21 connecting the water sample supply tank 30 and the sampler 1; if the water pipe is exposed to low temperatures that cause it to freeze, the temperature sensor will alarm and the heating device will work in conjunction to ensure that the water sample flows smoothly through the water pipe in the low temperature environment, so that the water sample can pass through the water pipe smoothly and finally be delivered to the sampler 1 for sampling.

[0023] The water sample supply tank 30 is equipped with a replaceable first external filter 32 and a second external filter 33 at its inlet 28 and outlet 27, respectively. If the filter becomes clogged during operation, the external filter can be removed for cleaning and then reinstalled for continued use.

[0024] When the system is working as a whole, the sewage sample flows through the following sequence: sampling pump 40 - second water line pipeline 22 - inlet 28 - water sample supply tank 30 - outlet 33 - first water line pipeline 21 - sampler 1.

[0025] When the wastewater sampling system is working, the sampling pump 40 is controlled by the timer 43 in the main control box 38 to pump water and take samples at regular intervals. After the sampling pump 40 works continuously for five minutes, the water level in the water sample supply tank 30 reaches the required amount for sampling. The stirrer 35 in the water sample supply tank 30 continues to work. Even if the sampling pump 40 fails and the sampling interval is long, or the wastewater 31 to be tested is left to stand for too long, the water sample can still be mixed evenly, ensuring the quality of the sample in the water sample supply tank 30.

[0026] When the liquid level is too high, the level gauge 34 alarms, the sampling pump 40 stops working, and the wastewater sample 31 to be tested, which is above the overflow port 37, is discharged from the overflow port 10 at the top of the supply tank 30; when the liquid level is too low, the sampling pump 40 starts to pump water to prevent the sampler 1 from having abnormal online data due to insufficient water supply.

[0027] When the wastewater sampling system is in operation, it works in tandem with multiple points, starting from sampling pump 40 and continuing until sampling is complete, achieving continuous 24-hour sampling. The system accurately determines the operating status of each controller based on sensor signals, enabling timely detection and troubleshooting of equipment anomalies. The sampling stages are clearly defined, the system is easy to assemble and install, can be adjusted according to site conditions, and is simple to maintain.

[0028] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
