Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a water sample collection and testing device. Background Technology

[0002] With the development of my country's economy, wastewater treatment has received increasing attention. Wastewater requires multiple treatment processes to meet discharge requirements. To ensure that discharged water samples meet standards, factories test the treated wastewater after each treatment step. Currently, this is done manually at different process points, with samples then sent to a laboratory for testing. However, the different process points are far apart, and each trip back and forth consumes a significant amount of time for testing personnel, increasing their workload. Furthermore, when collecting water samples, testing personnel can only take samples from the surface layer of the wastewater in the treatment tank. Surface wastewater contains more scum and impurities, and the measured values ​​from this layer cannot fully represent the treatment status of the wastewater in the tank. Therefore, manual sampling is not only time-consuming but also yields inaccurate results.

[0003] Therefore, there is an urgent need for a water sample collection and testing device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a water sample collection and testing device that can solve the problems that manual water sample collection is not only time-consuming, but also results in low accuracy.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A water sample collection and testing device, comprising:

[0007] The pipeline assembly includes a main pipeline and multiple branch pipelines. Each branch pipeline has an inlet and an outlet. The outlets of the multiple branch pipelines are connected to the main pipeline. The inlets of the multiple branch pipelines are connected to wastewater treatment tanks for different treatment processes. Each branch pipeline is equipped with a solenoid valve. One end of the main pipeline is closed. The suction device includes an inlet and an outlet. The other end of the main pipeline is connected to the inlet.

[0008] A water sample tank, which is connected to the outlet of the suction device, is configured to store water samples;

[0009] The testing device is configured to test the water sample in the water sample tank.

[0010] As a preferred technical solution for the water sample collection and testing device, the inlet end of the branch pipeline is placed at the middle liquid level of the sewage in the sewage treatment tank.

[0011] As a preferred technical solution for the water sample collection and testing device, the water sample collection and testing device further includes a control component, which includes a control panel and a button component. The control panel is electrically connected to the plurality of solenoid valves and the suction component, and the button component is electrically connected to the control panel.

[0012] As a preferred technical solution for the water sample collection and testing device, the suction component and the water sample tank are connected by a connecting pipe. The connecting pipe is also equipped with a check valve. When the water sample tank is filled with the water sample, the check valve is normally closed.

[0013] As a preferred technical solution for water sample collection and testing devices, a pressure gauge is provided on the connecting pipe.

[0014] As a preferred technical solution for the water sample collection and testing device, the connecting pipe is also equipped with a pressure relief valve, which is used to adjust the pressure value inside the connecting pipe.

[0015] As a preferred technical solution for the water sample collection and testing device, the water sample collection and testing device further includes a water return component, which is connected to the water sample tank and can selectively discharge the water sample in the water sample tank.

[0016] As a preferred technical solution for the water sample collection and testing device, the water return component includes a water return pipe and a control valve. The control valve is installed on the water return pipe. One end of the water return pipe is connected to the water sample tank, and the other end is connected to the sewage treatment tank.

[0017] As a preferred technical solution for water sample collection and testing devices, the testing component is a COD detector.

[0018] As a preferred technical solution for water sample collection and testing devices, each of the branch pipelines is equipped with a filter.

[0019] The beneficial effects of this utility model are as follows:

[0020] The water sample collection and testing device provided by this utility model consists of a main pipeline and multiple branch pipelines connecting the outlet end to the main pipeline. The inlet ends of the multiple branch pipelines are connected to sewage treatment tanks of different treatment processes. Each branch pipeline is equipped with a solenoid valve. When collecting a target water sample, it is only necessary to control the state of the solenoid valves on the multiple branch pipelines. The solenoid valve on the branch pipeline containing the target water sample is set to the open state, while the solenoid valves on other branch pipelines are set to the closed state. This allows the target water sample to be drawn into the water sample tank for testing. In this way, the testing personnel do not need to go to the corresponding process point to collect samples, avoiding the time wasted on each return trip. This reduces the workload of the testing personnel while completing the water sample testing. At the same time, the branch pipelines can be placed below the surface of the sewage in the sewage treatment tank, which can prevent the target water sample drawn into the water sample tank from containing scum and impurities, thereby improving the accuracy of the water sample testing results.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0028] like Figure 1 As shown, this embodiment provides a water sample collection and testing device, which includes a pipeline assembly 1, a suction component 2, a water sample tank 3, and a testing component 4. The pipeline assembly 1 includes a main pipeline 11 and multiple branch pipelines 12. Each branch pipeline 12 includes an inlet end and an outlet end. The outlet ends of the multiple branch pipelines 12 are all connected to the main pipeline 11, and the inlet ends of the multiple branch pipelines 12 are respectively connected to wastewater treatment tanks of different treatment processes. Each branch pipeline 12 is equipped with a solenoid valve 121, which is used to control the opening and closing of the branch pipeline 12. One end of the main pipeline 11 is closed. The suction component 2 includes an inlet and an outlet. The other end of the main pipeline 11 is connected to the inlet. The water sample tank 3 is connected to the inlet of the suction component 2 and is configured to store water samples. By operating the suction unit 2 and simultaneously controlling the on / off states of the solenoid valves 121 in multiple branch pipes 12, water samples from the target treatment process can be drawn into the water sample tank 3. The water sample in the water sample tank 3 is then tested using the detection unit 4. The water sample to be tested is called the target water sample. When drawing the target water sample, the solenoid valve 121 on the branch pipe 12 containing the target water sample can be set to the open state, while the solenoid valves 121 on other branch pipes 12 can be set to the closed state. This allows the target water sample to be drawn into the water sample tank 3, and the detection unit 4 can then test it. Furthermore, when placing the inlet ends of multiple branch pipes 12 in wastewater treatment tanks for different processes, the branch pipes 12 can be placed below the surface of the wastewater in the wastewater treatment tank to avoid the target water sample containing scum and impurities, thus improving the accuracy of the test results.

[0029] The water sample collection and testing device provided in this embodiment consists of a main pipeline 11 and multiple branch pipelines 12, each with its outlet connected to the main pipeline 11. The inlet ends of the branch pipelines 12 are connected to wastewater treatment tanks at different treatment stages. Each branch pipeline 12 is equipped with a solenoid valve 121. When collecting a target water sample, the solenoid valves 121 on the branch pipelines 12 are controlled. The solenoid valve 121 on the branch pipeline containing the target water sample is set to the open state, while the solenoid valves 121 on the other branch pipelines are set to the closed state. This allows the target water sample to be drawn into the water sample tank 3 for testing. This eliminates the need for testing personnel to collect samples at the corresponding process points, avoiding the significant time wasted on each return trip and reducing the workload of testing personnel while completing the water sample testing. Furthermore, the branch pipelines 12 can be placed below the surface of the wastewater in the wastewater treatment tank, thus preventing the target water sample drawn into the water sample tank 3 from containing scum and impurities, improving the accuracy of the water sample testing results.

[0030] In this embodiment, the suction component 2 can be a water pump.

[0031] In this embodiment, the inlet end of branch pipe 12 is positioned at the middle liquid level of the sewage in the sewage treatment tank. Because a large amount of scum and impurities float on the surface of the sewage in the sewage treatment tank, and a large amount of silt accumulates at the bottom, water samples taken from the surface and bottom of the sewage in the tank cannot represent the treatment status of the sewage. Taking water samples at the middle liquid level of the sewage in the tank further ensures the accuracy of the water sample test results.

[0032] For example, depending on the different wastewater treatment processes, multiple wastewater treatment tanks are specifically divided into a collection well, a regulating tank, an IC inlet tank, an IC effluent tank, a secondary sedimentation tank, a final sedimentation tank, and a disinfection tank. Therefore, the water sample collection and detection device provided in this embodiment includes 7 branch pipes 12, each branch pipe 12 corresponding to one wastewater treatment tank.

[0033] In this embodiment, the water sample collection and testing device also includes a control component, which comprises a control panel and a button assembly. The control panel is electrically connected to multiple solenoid valves 121 and the suction component 2, and the button assembly is electrically connected to the control panel. Thus, the testing personnel can draw the target water sample into the water sample tank 3 simply by operating the button assembly, without needing to manually control the opening and closing of the solenoid valves 121 at each branch pipe 12. This control component makes the water sample collection and testing work more convenient for the testing personnel.

[0034] Preferably, a programming module can be set up in the control panel, and a control program can be input into the programming module to automatically control the state of the suction component 2 and multiple solenoid valves 121 according to the detection requirements. This enables automated suction of water samples from multiple sewage treatment tanks, reducing manual intervention and improving the automation level of the water sample collection and detection device. Furthermore, a display screen can be provided on the control panel. The detection probe of the detection component 4 is placed inside the water sample tank 3. The detection component 4 can communicate with the control panel, and the display screen shows the detection data of the water sample sucked into the water sample tank 3 in real time, making it easier for testing personnel to understand the water sample detection results in real time. It is worth noting that the programming module and control program are conventional technical means in the field of electrical engineering and are not the focus of protection of this utility model.

[0035] In this embodiment, the suction device 2 and the water sample tank 3 are connected by a connecting pipe 20. A check valve 201 is provided on the connecting pipe 20. When the water sample tank 3 is filled with water sample, the check valve 201 is normally closed. The check valve 201 can prevent backflow of water sample in the water sample tank 3, and avoid the sludge deposited at the bottom of the sewage treatment tank being impacted by the backflow of water, which would make the sewage in the sewage treatment tank that has completed the treatment process turbid.

[0036] Furthermore, a pressure gauge 202 is installed on the connecting pipe 20. The pressure gauge 202 can monitor the pressure value of the connecting pipe 20 in real time. Based on the monitored pressure value, the suction force of the suction component 2 can be adjusted accordingly, so that the water sample can be drawn into the water sample tank 3 at a uniform and appropriate flow rate. This avoids the situation where the connection point between the main pipe 11, the branch pipe 12, the suction component 2 and the connecting pipe 20 becomes detached due to excessive suction force of the suction component 2, thereby improving the stability of the water sample collection and detection device.

[0037] Furthermore, a pressure relief valve 203 is also provided on the connecting pipe 20, which is used to regulate the pressure value inside the connecting pipe 20. Before pumping the target water sample, the testing personnel can first judge the state of the connecting pipe 20 based on the pressure value monitored by the pressure gauge 202. If the pressure value of the connecting pipe 20 is too high, the pressure relief valve 203 can be opened to regulate the pressure value inside the connecting pipe 20, so as to avoid the problem of the connection point between the main pipeline 11, the branch pipeline 12, the suction device 2 and the connecting pipe 20 becoming detached during the water sample pumping process.

[0038] In this embodiment, the water sample collection and testing device further includes a water return component 5, which is connected to the water sample tank 3 and can selectively discharge the water sample inside the water sample tank 3. Specifically, the water return component 5 is connected to a collection well, which is the sewage treatment tank corresponding to the initial step in the sewage treatment process. Therefore, returning the tested water sample from the water sample tank 3 to the collection well will not affect the sewage treatment results.

[0039] For example, the water return assembly 5 includes a water return pipe 51 and a control valve 52. The control valve 52 is installed on the water return pipe 51, and one end of the water return pipe 51 is connected to the water sample tank 3, while the other end is connected to the sewage treatment tank, i.e., the water return pipe 51 is connected to the collection well. By adjusting the closing of the control valve 52, the water sample in the water sample tank 3 can be selectively discharged to the collection well.

[0040] In this embodiment, the detection component 4 is a COD detector. A COD detector is a water quality monitoring instrument that can monitor the content of organic matter in water, thereby determining the water quality. COD detectors are commonly used instruments for water quality monitoring and will not be described in detail here.

[0041] Preferably, each branch pipe 12 is equipped with a filter. The filter can filter impurities in the target water sample drawn into the water sample tank 3, thereby further improving the accuracy of the target water sample test results and the accuracy of the wastewater treatment result test data. The structure and working principle of the filter can be referred to in the prior art, and will not be described in detail here.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
