Description

Technical Field

[0001] This disclosure relates to the field of detection probe cleaning technology, specifically to an online detection probe cleaning device. Background Technology

[0002] The detection probe, equipped with corresponding instruments, can be used to detect chemical parameters in liquids. For example, when inserted into a liquid delivery pipeline, the probe can be used to detect the pH value or oxygen content of the liquid. After a period of use, impurities from the liquid will adhere to the probe, affecting the accuracy and lifespan of the measurement. Cleaning is necessary. In related technologies, the probe needs to be disassembled, manually cleaned, and then reinserted into the liquid delivery pipeline, a rather cumbersome process. Utility Model Content

[0003] The purpose of this disclosure is to provide an online cleaning device for detection probes, which can clean the detection probes without removing them from the liquid delivery pipeline, making the cleaning process simple and convenient.

[0004] To achieve the above objectives, this disclosure provides an online cleaning device for detection probes, used for cleaning detection probes inserted into liquid delivery pipelines. The online cleaning device for detection probes includes:

[0005] Compressed air source; and

[0006] A nozzle, connected to the compressed air source, is used to be inserted into the liquid delivery pipeline and located on the opposite side of the detection probe in the extension direction of the detection probe, so as to clean the detection probe.

Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] In this disclosure, for ease of explanation, an X-direction is established for the measuring cylinder, where the X-direction is the extension direction of the detection probe. Unless otherwise stated, "inner" and "outer" refer to the inner and outer contours of the corresponding components. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another.

[0026] This disclosure provides an online cleaning device for a detection probe, such as... Figures 1 to 3 As shown, the online cleaning device for the detection probe can be used to clean the detection probe 60 that is inserted into the liquid delivery pipeline 70. The online cleaning device for the detection probe includes a compressed air source 10 and a nozzle 40. The nozzle 40 is connected to the compressed air source 10 and can supply air to the compressed air source 10. The nozzle 40 is inserted into the liquid delivery pipeline 70 and is located on the opposite side of the detection probe 60 in the extending direction of the detection probe 60, and can clean the detection probe 60.

[0027] In the above embodiment, the liquid delivery pipeline 70 contains liquid, and the detection probe 60 is inserted into the liquid delivery pipeline 70. The detection probe 60, in conjunction with corresponding instruments and equipment, can be used to detect the pH value or oxygen content of the liquid in the liquid delivery pipeline 70. The nozzle 40 is inserted into the liquid delivery pipeline 70 and is located on the opposite side of the detection probe 60 in the extending direction of the detection probe 60. Compressed gas supplied by the air source 10 to the nozzle 40 can be ejected from the nozzle 40. The high-velocity gas ejected from the nozzle 40 can drive the liquid in the liquid delivery pipeline 70 to flow towards the detection probe 60, thereby flushing away impurities adhering to the detection probe 60 and cleaning it. With this setup, the detection probe 60 can be cleaned online without being removed from the liquid delivery pipeline 70. The cleaning process is simple and convenient.

[0028] In addition, such as Figure 1 and Figure 3 As shown, the nozzle 40 is used to be inserted into the liquid delivery pipeline 70 and is located on the opposite side of the detection probe 60 in the extension direction of the detection probe 60. The gas sprayed from the nozzle 40 drives the liquid to flow, and the driven liquid can directly flush the detection probe 60, thereby reducing the obstruction of the inner wall of the pipeline and achieving a better flushing and cleaning effect on the detection probe 60.

[0029] In some embodiments, the liquid delivery pipeline 70 may include a measuring cylinder 71, which is connected to an upstream delivery pipeline 72 and a downstream delivery pipeline 73. The upstream delivery pipeline 72 may be connected to upstream equipment, and the downstream delivery pipeline 73 may be connected to downstream equipment. Depending on the application scenario, the liquid delivered in the liquid delivery pipeline 70 may vary. For example, the liquid delivery pipeline 70 may be used in a wastewater treatment system to deliver wastewater. Of course, the liquid delivered by the liquid delivery pipeline 70 is not limited to this.

[0030] In some implementations, such as Figure 1 and Figure 3 As shown, the detection probe 60 can be inserted into the measuring cylinder 71 and can be used to detect the liquid in the measuring cylinder 71 (e.g., detect the pH value or oxygen content of the liquid). The nozzle 40 can be inserted into the measuring cylinder 71 and can be located on the opposite side of the extension direction of the detection probe 60. The gas sprayed from the nozzle 40 drives the liquid to flow, and the liquid driven by the gas can directly wash the detection electrode part of the detection probe 60 for direct rinsing of the detection electrode part of the detection probe 60. Of course, the liquid driven by the gas sprayed from the nozzle 40 can also wash other parts of the detection probe 60 for cleaning, which will not be described in detail here.

[0031] In some embodiments, the online probe cleaning device further includes a filter pressure reducer 30. The compressed air source 10 is connected to the nozzle 40 through the filter pressure reducer 30. On the one hand, the filter pressure reducer 30 can filter the gas from the compressed air source 10 to the nozzle 40, making the gas from the compressed air source 10 to the nozzle 40 cleaner and preventing impurities from being introduced into the liquid delivery pipeline 70. On the other hand, the filter pressure reducer 30 can regulate the pressure of the gas from the compressed air source 10 to the nozzle 40, so that the pressure of the gas to the nozzle 40 reaches a preset pressure value, thereby ensuring the cleaning effect of the online probe cleaning device on the probe 60.

[0032] In the above embodiments, the compressed air source 10 and the filter pressure reducer 30 can be connected by a pipeline, and the filter pressure reducer 30 and the detection probe 60 can be connected by a pipeline, which will not be described in detail here.

[0033] In some implementations, the filter pressure reducer 30 may be positioned at a higher vertical height than the measuring cylinder 71 to prevent liquid in the measuring cylinder 71 from flowing back into the filter pressure reducer 30 through the nozzle 40.

[0034] Furthermore, in embodiments not shown, a check valve may be provided between the filter pressure regulator 30 and the nozzle 40 to prevent liquid in the liquid delivery line 70 from flowing back into the filter pressure regulator 30.

[0035] In some other embodiments not shown, the online cleaning device for the detection probe includes a gas filter, through which the compressed air source 10 is connected to the nozzle 40. The gas filter can filter the gas from the compressed air source 10 to the nozzle 40, making the gas from the compressed air source 10 to the nozzle 40 cleaner.

[0036] In the above embodiments, the online cleaning device for the detection probe also includes a pressure reducing valve. A pressure reducing valve is provided on the pipeline connecting the gas filter to the nozzle 40. The pressure reducing valve can adjust the pressure of the gas supplied to the nozzle 40 to a preset pressure to ensure the cleaning effect of the online cleaning device for the detection probe 60.

[0037] As mentioned above, the online cleaning device for the detection probe also includes a filter regulator 30, and the compressed air source 10 is connected to the nozzle 40 through the filter regulator 30.

[0038] In some implementations, such as Figure 1 and Figure 2 As shown, a control valve 20 is installed on the pipeline connecting the compressed air source 10 and the filter pressure reducer 30. The control valve 20 is used to control the opening and closing of the pipeline connecting the compressed air source 10 and the filter.

[0039] In the above embodiment, the compressed air source 10 and the filter regulator 30 are connected by a pipeline. A control valve 20 is installed on the pipeline connecting the compressed air source 10 and the filter regulator 30. The control valve 20 can be used to control the opening and closing of the connection between the compressed air source 10 and the filter. In addition, the control valve 20 can also regulate the flow rate of the gas from the compressed air source 10 to the filter regulator 30.

[0040] In some embodiments, the control valve 20 may be configured in any suitable form; for example, the control valve 20 may be configured as an electromagnetic flow control valve 200.

[0041] In some other possible implementations, the control valve 20 may also be configured as a solenoid ball valve, which is not limited here.

[0042] In some implementations, such as Figure 1 and Figure 2 As shown, the online cleaning device for the detection probe also includes a control device 50, which is communicatively connected to the electromagnetic flow regulating valve 200. The control device 50 is configured to cyclically control the opening and closing of the electromagnetic flow valve according to a preset opening time period, so that the online cleaning device for the detection probe 60 can clean the detection probe 60 at regular intervals.

[0043] In the above embodiments, the communication connection between the electromagnetic flow regulating valve 200 and the control device 50 can be an electrical connection via a wire, and there is no limitation here.

[0044] Furthermore, the control device 50 can be configured in any suitable form. For example, the control device 50 can be configured as a PLC controller, with the solenoid valve communicating with the PLC controller, which can control the opening and closing of the solenoid flow valve. It should be understood that the solenoid flow valve can be opened periodically by the PLC controller. After the solenoid flow valve has been opened for a preset cleaning time period, the PLC controller will then control the solenoid flow valve to close. After another preset opening time period, the PLC controller will then open the solenoid flow regulating valve 200, and after another preset cleaning time period, the PLC controller will then control the solenoid flow regulating valve 200 to close, continuously cycling through the above process.

[0045] In other embodiments, the control device 50 may include an electrical control box, and the electromagnetic flow regulating valve 200 may be connected to the electrical control box. The opening and closing of the electromagnetic flow regulating valve 200 can be controlled by the electrical control box. The electrical control box can control the opening of the electromagnetic flow regulating valve 200 after each preset opening time period and control the closing of the electromagnetic flow regulating valve 200 after the preset cleaning time period, so that the online cleaning device for the detection probe can complete the cleaning of the electromagnetic flow regulating valve 200.

[0046] In some implementations, the electrical control box may include components such as protective switches, timers, and relays. The connection relationships of these components and their connection relationships with the electromagnetic flow regulating valve 200 are common practices in related technologies and will not be elaborated here.

[0047] It should be noted that the electrical control box mentioned above can be a conventional electrical control box, as long as it can achieve the above functions; there are no restrictions here.

[0048] In some embodiments, the compressed air source 10 can be configured in any suitable form. For example, the compressed air source 10 can be configured as a compressed air tank 100, through which air is supplied to the nozzle 40.

[0049] In addition, the compressed air source 10 can also be constructed in other forms. For example, the compressed air source 10 can also be constructed as a compressed air delivery pipeline in a factory. The compressed air delivery pipeline is connected in sequence to the electromagnetic flow regulating valve 200, the filter pressure reducer 30 and the nozzle 40, for delivering compressed gas to the nozzle 40, and then for cleaning the detection probe 60.

[0050] In some embodiments, the nozzle 40 may be constructed in any suitable form. For example, the nozzle 40 may be constructed as a stainless steel nozzle 400, or as a polyvinyl chloride (PVC) pipe, without limitation.

[0051] The following is in conjunction with the appendix Figures 1 to 3 The working process of the online cleaning device for the detection probe is briefly described. For example, Figure 1 and Figure 2 As shown, the online cleaning device for the detection probe includes a compressed air tank 100, an electromagnetic flow regulating valve 200, a control device 50, a filter pressure regulator 30, and a nozzle 40. The nozzle 40 is inserted into the measuring cylinder 71 and located on the opposite side of the extension direction of the detection probe 60. The compressed air tank 100 is connected to the air inlet of the electromagnetic flow regulating valve through a pipeline. The air outlet of the electromagnetic flow regulating valve is connected to the air inlet of the filter pressure regulator 30 through a pipeline. The air outlet of the filter pressure regulator 30 is connected to the nozzle 40 through a pipeline.

[0052] First, the control device 50 (e.g., a PLC controller or electrical control box) sets a preset start time period and a preset cleaning time period. After the preset start time period, the control device 50 controls the electromagnetic flow valve to open. Gas in the compressed gas tank 100 passes through the electromagnetic flow regulating valve 200 and then into the filter pressure regulator 30. The filter pressure regulator 30 filters and regulates the pressure of the incoming compressed gas before it is introduced into the nozzle 40. The compressed gas is sprayed out through the nozzle 40, and the compressed gas drives the liquid in the measuring cylinder 71 to flush the detection probe 60, cleaning the impurities attached to the detection probe 60. After the preset cleaning time period, the control device 50 controls the electromagnetic flow regulating valve 200 to close. After the preset start time period, the control device 50 controls the electromagnetic flow regulating valve 200 to open, continuously cycling to periodically clean the detection probe 60.
