Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow channel technology, and in particular to ultrasonic cleaning flow channel. Background Technology
[0002] In the field of modern environmental monitoring and water quality analysis, the flow channel, as a key component of online water quality monitoring systems, directly affects the accuracy and reliability of the test results. Existing online water quality monitoring flow channels suffer from several problems in practical applications: Firstly, after prolonged use, impurities, microorganisms, scale, and other contaminants easily adhere to the surface of the measuring electrodes. These contaminants interfere with the electrodes' detection of water quality parameters, leading to deviations or even distortions in the test data, severely impacting the accuracy and validity of the results and failing to meet the demands for high-precision, real-time monitoring. Secondly, existing flow channels lack efficient and convenient cleaning methods. When the measuring electrodes or the inside of the flow channel become contaminated, manual disassembly and cleaning are usually required. This is not only cumbersome and time-consuming but also prone to damaging the measuring electrodes and flow channel components, reducing the equipment's lifespan and the continuity of monitoring operations. Therefore, there is an urgent need to design a new type of flow channel that can effectively clean the measuring electrodes and maintain a stable flow rate to ensure the accuracy and efficiency of online water quality monitoring. Utility Model Content
[0003] The purpose of this invention is to provide an ultrasonic cleaning flow tank to solve the problems of easy electrode contamination, unstable flow rate, and inconvenient cleaning in existing online water quality detection flow tanks, thereby ensuring the accuracy and efficiency of online water quality detection.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaning flow tank, comprising:
[0005] The main body of the flow channel is used to install measuring electrodes during online water quality detection, and the main body of the flow channel is provided with a flow guiding structure to maintain a stable flow rate.
[0006] An ultrasonic transducer is fixedly installed on the back of the flow channel body, and the ultrasonic transducer is in close contact with the back of the flow channel body for ultrasonic cleaning of the interior of the flow channel body.
[0007] A drive control module is disposed outside the main body of the flow channel. The drive control module is used to provide power to the ultrasonic transducer and realize control.
[0008] As a further improvement to the technical solution of this utility model, at least one measuring electrode is installed in the main body of the flow channel. The measuring electrode is used to detect water quality. At least one measuring cavity is opened inside the main body of the flow channel, and the measuring electrode is installed in the measuring cavity to complete the detection of the water sample being tested.
[0009] As a further improvement to the technical solution of this utility model, a measuring electrode mounting hole is provided on the top of the main body of the flow channel, and the number of the measuring electrode mounting holes is at least one, corresponding to the number of measuring cavities; the measuring electrode mounting hole is connected to the measuring cavity, and the measuring electrode enters the measuring cavity through the measuring electrode mounting hole.
[0010] As a further improvement to the technical solution of this utility model, a water inlet connector is fixedly installed at the bottom of the main body of the flow channel, and the water inlet connector is connected to the measuring cavity through a pipe.
[0011] As a further improvement to the technical solution of this utility model, an inlet regulating valve is provided between the water inlet connector and the measuring cavity.
[0012] As a further improvement to the technical solution of this utility model, a guide pipe is fixedly connected to one end of the measuring cavity, and a drain pipe is connected to the other end of the guide pipe. One end of the drain pipe penetrates the bottom of the main body of the flow channel.
[0013] As a further improvement to the technical solution of this utility model, the drive control module is provided with an ultrasonic transducer power output terminal and a control module power input terminal on one side. An ultrasonic transducer power cable is fixedly connected to one side of the ultrasonic transducer. One end of the ultrasonic transducer power cable is electrically connected to the ultrasonic transducer power output terminal. The control module power input terminal is electrically connected to an external power source to provide working power to the drive control module.
[0014] As a further improvement to the technical solution of this utility model, the measuring cavity is a cylindrical cavity structure with a diameter of 18-19mm and a depth of 100-150mm.
[0015] As a further improvement to the technical solution of this utility model, the vertical distance between the ultrasonic transducer and the rear wall of the measuring cavity is 3-7mm.
[0016] As a further improvement to the technical solution of this utility model, the axis of the measuring electrode mounting hole intersects perpendicularly with the central axis of the measuring cavity.
[0017] Furthermore, in use, an ultrasonic transducer is installed at a fixed position on the back of the main body of the flow channel. The ultrasonic transducer is powered and controlled by the drive control module through the power output terminal of the ultrasonic transducer. Then, the water sample to be tested can be introduced into the main body of the flow channel through the water inlet connector, and the water sample flow rate is controlled by the water inlet regulating valve. The water sample to be tested flows into the measuring cavity through the inside of the flow channel for measurement by the measuring electrode. The measuring electrode is inserted into the measuring cavity through the measuring electrode mounting hole. The water sample to be tested is discharged from the main body of the flow channel through the guide pipe and then through the drain pipe. When the drive control module (model HWUC-02) triggers the ultrasonic transducer to start, dirt that falls off the surface of the object flows through the guide pipe and then through the drain pipe to be discharged from the measuring flow channel, thus completing the cleaning of the inside of the main body of the flow channel.
[0018] In this invention, the ultrasonic self-cleaning measuring flow tank is equipped with a dedicated ultrasonic transducer and a dedicated drive control module on the back of the measuring flow tank. It uses the principle of high-frequency ultrasonic vibration to clean the inside of the measuring tank and the measuring electrodes in the mounting holes at regular intervals, thereby maintaining the cleanliness function and reducing manual maintenance costs.
[0019] In this invention, the ultrasonic self-cleaning measuring flow channel uses ultrasonic vibration technology. High-frequency vibration causes tiny bubbles in the liquid inside the measuring chamber to impact the surface of the dirt, causing the dirt inside the measuring chamber and the dirt on the surface of the measuring electrodes to fall off. The ultrasonic transducer on the back of the flow channel body is installed at a certain distance from the measuring chamber, ensuring that the cleaning function is efficient and stable.
[0020] Compared with the prior art, the ultrasonic cleaning flow tank of the present invention has the following advantages:
[0021] High-efficiency cleaning function: By installing an ultrasonic transducer on the back of the flow channel body, the cavitation effect of ultrasonic waves can effectively remove contaminants from the surface of the measuring electrode and the inside of the flow channel. No manual disassembly and cleaning is required, which greatly improves cleaning efficiency and ensures the accuracy of test data.
[0022] Stable flow rate control: The flow guiding structure inside the main body of the flow channel can optimize the water flow distribution, maintain a stable flow rate, and ensure that the water sample flows stably in the flow channel, thereby improving the detection effect of the measuring electrode on water quality.
[0023] The structural design is reasonable: the dimensions of the measuring chamber and the positional relationship between the measuring electrode mounting holes and the measuring chamber facilitate the installation of the measuring electrodes and the testing of water samples. The appropriate distance between the ultrasonic transducer and the measuring chamber ensures the cleaning effect of the ultrasonic waves.
[0024] Easy to operate: The drive control module makes the power supply and control of the ultrasonic transducer more convenient, and the working parameters of the ultrasonic transducer can be flexibly adjusted according to actual needs. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1
[0038] Reference Figure 1-6 An ultrasonic cleaning flow tank includes: a flow tank body 100, an ultrasonic transducer 1, and a drive control module;
[0039] The main body 100 of the flow channel is used to install measuring electrodes 200 and provide a stable flow rate when the water quality is detected online. The main body 100 of the flow channel can install at least one measuring electrode 200, which is used to detect the water quality. Different models of flow channels can install different numbers of measuring electrodes 200, with a maximum of three measuring electrodes 200.
[0040] The main body 100 of the flow channel also includes a measuring cavity 6 opened inside it. The measuring cavity 6 cooperates with the measuring electrode 200 to complete the detection of the water sample to be tested.
[0041] The main body 100 of the flow channel also includes a measuring electrode mounting hole 5 opened on its top. The number of measuring electrode mounting holes 5 corresponds to the measuring cavity. The measuring electrode mounting holes 5 are connected to the measuring cavity 6 and are used for mounting the measuring electrode 200.
[0042] The ultrasonic transducer 1 is fixedly installed on the back of the flow channel body 100. The ultrasonic transducer 1 is used to perform ultrasonic cleaning on the inside of the flow channel body 100. A circular groove 101 for installing the ultrasonic transducer 1 is opened on the back of the flow channel body 100.
[0043] The drive control module is used in conjunction with the main body 100 of the flow channel. One side of the drive control module has an ultrasonic transducer power output terminal 9 and a control module power input terminal 10. An ultrasonic transducer power cable 2 is fixedly connected to one side of the ultrasonic transducer 1. The other end of the ultrasonic transducer power cable 2 is connected to the ultrasonic transducer power output terminal 9 to supply power to the ultrasonic transducer 1. The control module power input terminal 10 is connected to an external power source to provide operating power to the drive control module. The drive control module uses a 220V AC power supply and is used to provide power to the ultrasonic transducer 1 and achieve control. It should be noted that the specific circuit structure of the drive control module includes an AC-DC conversion module (input 220V AC, output 24V DC), a PWM control chip (model STM32F103), and a power amplifier circuit. The ultrasonic transducer drive frequency range is 20-40kHz, and the cleaning cycle (adjustable from 1-24 hours) can be set via the control panel.
[0044] This application can be used in the field of flow channel technology, or in other fields applicable to this application. Example 2
[0045] refer to Figure 1 , 3 -6. Improvement based on Example 1: Ultrasonic self-cleaning function measurement flow channel, which is applied to the field of flow channel technology;
[0046] In this embodiment, a water inlet connector 8 is fixedly installed at the bottom of the flow channel body 100. The water inlet connector 8 is connected to the measuring chamber 6 through a pipe and is used to input the water sample to be measured.
[0047] In this embodiment, an inlet regulating valve 7 is provided between the water inlet connector 8 and the measuring chamber 6. The inlet regulating valve 7 is used to regulate the flow rate of the input water sample.
[0048] In this embodiment, a guide pipe 3 is fixedly connected to one end of the measuring cavity 6, and a drain pipe 4 is connected to the other end of the guide pipe 3. One end of the drain pipe 4 penetrates the bottom of the flow tank body 100, and the drain pipe 4 is used to discharge the water sample after testing.
[0049] In this embodiment, the measuring cavity 6 is a cylindrical cavity structure with a diameter of 18-19 mm and a depth of 100-150 mm. After multiple experimental verifications, the measuring cavity 6 within this size range can well meet the installation requirements of the measuring electrode 200 and the water sample detection requirements, while also facilitating effective cleaning of the interior of the measuring cavity 6 by the ultrasonic transducer 1. It should be noted that the inner wall of the measuring cavity 6 is mirror-polished (roughness Ra≤0.8μm) and made of 316L stainless steel or polytetrafluoroethylene (PTFE) to prevent water sample corrosion and dirt adhesion.
[0050] Specifically, the vertical distance between the ultrasonic transducer 1 and the rear wall of the measuring cavity 6 is 3-7 mm. This distance ensures that the ultrasonic energy generated by the ultrasonic transducer 1 is effectively transmitted into the measuring cavity 6, achieving a good cleaning effect. It should be noted that the specific model of the ultrasonic transducer 1 is ZTA-200, with dimensions of 50mm × 50mm × 5mm.
[0051] Furthermore, the axis of the measuring electrode mounting hole 5 intersects perpendicularly with the central axis of the measuring cavity 6. This structural design allows the measuring electrode 200 to be inserted vertically into the measuring cavity 6, facilitating full contact between the measuring electrode 200 and the water sample and improving the accuracy of the detection.
[0052] The working principle and usage process of this technical solution are as follows:
[0053] In use, an ultrasonic transducer 1 is fixedly installed on the back of the main body 100 of the flow channel. The ultrasonic transducer 1 is powered and controlled by the drive control module through the power output terminal 9 of the ultrasonic transducer 1. Then, the water sample to be tested can be introduced into the main body 100 of the flow channel through the water inlet connector 8. At the same time, the water sample flow rate is controlled by the water inlet regulating valve 7. The water sample to be tested flows into the measuring chamber 6 through the inside of the flow channel for the measuring electrode 200 to measure. The measuring electrode 200 is inserted into the measuring chamber 6 through the measuring electrode mounting hole 5. The water sample to be tested is discharged from the main body 100 of the flow channel through the guide pipe 3 and then through the drain pipe 4. When the drive control module triggers the ultrasonic transducer 1 to start, dirt that falls off the surface of the object flows through the guide pipe 3 and then through the drain pipe 4 to be discharged from the measuring flow channel, thus completing the cleaning of the inside of the main body 100 of the flow channel.

Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model.
