Description

Technical Field

[0001] This utility model relates to the field of water quality testing, and in particular to a multi-parameter flow path system for automatic quality control. Background Technology

[0002] In water quality monitoring of natural water bodies such as rivers, lakes, and oceans, multi-parameter equipment can monitor water temperature, pH, dissolved oxygen, conductivity, and turbidity parameters in real time and accurately, providing crucial data support for assessing water quality, ecological health, and pollution levels. However, in practical applications, traditional multi-parameter equipment faces numerous challenges. For example, the equipment is susceptible to interference from environmental factors such as temperature fluctuations and electromagnetic radiation, which can lead to measurement deviations. Over long-term operation, sensor performance gradually degrades, reducing measurement accuracy. Furthermore, manual quality control is labor-intensive, time-consuming, and difficult to ensure accuracy and consistency. These issues significantly limit the reliability and effectiveness of traditional multi-parameter equipment. Utility Model Content

[0003] The purpose of this invention is to provide an automatic quality control multi-parameter flow path system to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0005] An automatic quality control multi-parameter flow path system includes a drain valve with a controllable valve port. The drain valve has a wastewater port, a waste liquid port, a raw water port, a cleaning port, and multiple standard sample ports. Each standard sample port is connected to a standard sample containing a standard liquid. The system also includes a peristaltic pump connected to the drain valve and multiple electrode sensors connected to the peristaltic pump.

[0006] Each electrode sensor detects different water quality parameters. The peristaltic pump pumps raw water to each electrode sensor to detect water quality parameters. The peristaltic pump can also pump standard solution to the corresponding electrode sensor to calibrate the electrode sensor.

[0007] Preferably, each electrode sensor has a through valve that is opened and closed in a controlled manner.

[0008] Preferably, the peristaltic pump can pump liquid into the electrode sensor, or it can pump the liquid in the electrode sensor in reverse to the drain valve and discharge it through the corresponding valve port.

[0009] Preferably, the electrode sensor is equipped with a liquid level detection structure. After the standard solution enters the corresponding electrode sensor, the liquid level detection mechanism measures the liquid level height of the standard solution in the electrode sensor, and stops the peristaltic pump from pumping the standard solution after the calibration height is reached.

[0010] Preferably, the electrode sensor also has an overflow structure, which discharges excess raw water to the outside after the raw water enters the electrode sensor.

[0011] Preferably, the liquid level detection structure does not detect the raw water after it enters the electrode sensor.

[0012] Preferably, after calibrating the electrode sensor, the standard solution is backflowed into the drain valve and discharged through the waste liquid outlet.

[0013] The beneficial effects of this utility model are:

[0014] The multi-parameter flow path system proposed in this invention is equipped with a peristaltic pump to provide power to multiple flow sections, and a drain valve to switch valve ports. Thus, combined with program control, the multi-parameter flow path system can not only measure water quality, but also perform self-calibration. Attached Figure Description

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] Example 1

[0024] This embodiment proposes an automated quality control multi-parameter flow path system. Please refer to [link / reference]. Figures 1-4 The multi-parameter flow path system includes a drain valve 1 with controllable opening and closing of its ports. The drain valve 1 has wastewater inlet, waste liquid inlet, raw water inlet, cleaning inlet, and six standard sample inlets. Each standard sample inlet is connected to a... Figure 2 As shown in the standard sample 4, the drain valve 1 is also connected to a peristaltic pump 5, which in turn is connected to four electrode sensors 6. It should be noted that each electrode sensor 6 has a through valve 7, which is controlled to open and close. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 The electrode sensor 6 includes a flow section 61 with an internal accommodating chamber. At the bottom of the flow section 61 is a liquid inlet 64 communicating with the chamber. The liquid inlet 64 is connected to the aforementioned straight-through valve 7 via a pipe. There is also an overflow port 66 communicating with the chamber on the side of the flow section 61. Below the overflow port 66 is a liquid level sensor 65 for detecting the liquid level in the accommodating chamber. The electrode sensor 6 also includes a sensor 62 for detecting water quality parameters. The sensor 62 is fixed in the flow section 61 by a nut 63 at the bottom. It should be noted that in this embodiment, there are four electrode sensors 6. The sensor 62 in each electrode sensor 6 detects different items. Specifically, one sensor 62 detects pH, and the other three sensors 62 detect turbidity, dissolved oxygen, and conductivity, respectively.

[0025] The multi-parameter flow path system proposed in this embodiment can detect water quality parameters. Please refer to [link / reference]. Figure 2 The raw water inlet in drain valve 1 is connected to raw water tank 2 via a pipe. After connection, peristaltic pump 5 pumps raw water from raw water tank 2 into all flow sections 61. Subsequently, the raw water is detected by sensors 62 in each flow section 61. During detection, the raw water can be discharged outward through overflow port 66, or the peristaltic pump 5 can be reversed to allow the raw water to enter drain valve 1 and be discharged outward through wastewater port. The multi-parameter flow path system proposed in this embodiment is self-calibrating. Please refer to [link / reference]. Figure 2The drain valve 1 is connected to six standard samples 4. During calibration, when any sensor 62 needs to be calibrated, the standard solution in the corresponding standard sample 4 can be pumped into the corresponding flow section 61 via the peristaltic pump 5, thereby performing numerical calibration on the sensor 62 corresponding to that flow section 61. It should be noted that when any sensor 62 is being tested, the straight-through valves 7 corresponding to other sensors 62 are in a closed state. Thus, the corresponding standard sample 4 can only enter the corresponding flow section 61. During calibration, the peristaltic pump 5 is controlled by the liquid level sensor 65. Specifically, when the standard solution enters the accommodating chamber and reaches the liquid level required for calibration, the liquid level sensor 65 gives a signal to stop the peristaltic pump 5, thereby preventing the standard solution from overflowing from the overflow port 66 (to prevent the standard solution from polluting the environment after flowing out of the overflow port 66). After the calibration of the sensor 62 is completed, the peristaltic pump 5 reverses its rotation, allowing the standard solution in the flow section 61 to enter the drain valve 1 and be discharged through the waste liquid port, and then centrally treated in a dedicated waste liquid tank 3. The multi-parameter flow path system proposed in this embodiment can clean the pipeline during self-calibration to prevent interference from residual standard solution in the pipeline or device. Please refer to [link to relevant documentation]. Figure 2 The drain valve 1 has a cleaning port, which is connected to clean water. To further explain, after the calibration of sensor 62 is completed, clean water can be injected into the flow section 61 via peristaltic pump 5. Then, the clean water in the flow section 61 is pumped in reverse to drain valve 1 and discharged through the waste liquid port. Repeating this process cleans the entire system's piping and components, preventing residual standard solution from causing detection or calibration errors.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
