[0033] See also Figure 1 The embodiment of the present utility model provides a leakage collection and alarm device for a dosing pump 20, comprising:

[0034] The collecting tray 10 is arranged below the dosing pump 20 and is used to collect leaked liquid to ensure that the leaked liquid does not flow directly to the ground or other equipment, thereby ensuring the cleanliness and safety of the production environment. The feed end of the dosing pump 20 is equipped with a feed pipeline 21, which is used to provide stable dosing liquid to ensure the continuity of the production process. The discharge end of the dosing pump 20 is equipped with a delivery pipeline 22 for transporting the raw materials pumped out by the dosing pump 20 to the next process.

[0035] The calibration column 30 is installed in parallel on the material delivery pipeline 22 and is used to monitor the liquid flow and pressure in the material delivery pipeline 22 to ensure the normal operation of the material delivery pipeline 22. The reading of the calibration column 30 can be used to determine whether there is any abnormality in the material delivery pipeline 22, providing a basis for subsequent leakage judgment.

[0036] The leakage liquid collection box 40 is used to collect the leaked liquid flowing out of the collection tray 10. The liquid inlet of the leakage liquid collection box 40 is connected to the collection tray 10 through the collection pipe 41, and the liquid outlet end of the leakage liquid collection box 40 is connected to the dosing pump 20 through the infusion pipe 42 to form a circulation loop to avoid waste of added liquid. A first control valve 43 is installed on the infusion pipe 42 to control the backflow of the leaked liquid. The leakage liquid collection box 40 is provided with a breathing pipe 44, one end of the breathing pipe 44 is connected to the inside of the leakage liquid collection box 40, and the other end is connected to the downstream end of the calibration column 30 to ensure the pressure balance in the leakage liquid collection box 40.

[0037] The liquid level measuring component 50 is installed on the leakage liquid collection box 40 and is used to monitor the liquid level changes in the leakage liquid collection box 40 in real time. A liquid level alarm module is provided in the liquid level measuring component 50. The liquid level measuring component 50 is also provided with an upper liquid point 51 and a lower liquid point 52 for determining the upper and lower limits of the alarm. The upper liquid point 51 and the lower liquid point 52 are both connected to the liquid level alarm module sensor. When the liquid level exceeds the preset upper and lower limits, the liquid level alarm module will send an alarm signal.

[0038] The control component is the core control part of the entire leakage collection and alarm device. It is electrically connected to the first control valve 43, the calibration column 30, the dosing pump 20 and the liquid level alarm module. The control component can automatically control the switch of the first control valve 43 and the start and stop of the dosing pump 20 according to the signal of the liquid level measuring component 50. At the same time, the control component can also receive the signal from the calibration column 30 to monitor and judge the operating status of the feed pipeline 22. Once a leak occurs, the control component will immediately start the alarm program, sound an alarm through the liquid level alarm module, and use the dosing pump 20 to pump back the leaked liquid in the leakage liquid collection box 40, ensuring production safety while avoiding waste of dosing liquid.

[0039] In this embodiment, the upstream end and the downstream end of the calibration column 30 are connected to the material delivery pipeline 22 through the first branch pipe 31 and the second branch pipe 32 respectively. This design allows the calibration column 30 to be flexibly connected to the material delivery pipeline 22, which is convenient for installation, maintenance and replacement of the calibration column 30 without affecting the normal operation of the material delivery pipeline 22. The first branch pipe 31 and the second branch pipe 32 are respectively installed with a second control valve 33 and a third control valve 34. These two control valves can control the upstream and downstream flow of the calibration column 30, thereby ensuring that the calibration column 30 can accurately and stably monitor the material delivery. The flow rate and pressure of the pipeline 22, the second control valve 33 and the third control valve 34 are electrically connected to the control component, so that the control component can adjust the working state of the calibration column 30 by controlling the switch of the two control valves according to actual needs. One end of the breathing tube 44 is arranged between the downstream end of the calibration column 30 and the third control valve 34, and is connected to the second branch pipe 32. This design ensures the pressure balance between the leakage liquid collection box 40 and the calibration column 30, prevents liquid leakage or reflux problems caused by pressure differences, and thus ensures the stable operation of the entire system.

[0040] A fifth control valve 23 is installed on the feed pipeline 21, and the liquid outlet end of the infusion pipeline 42 can be connected to the feed pipeline 21 through the fifth control valve 23. The fifth control valve 23 is electrically connected to the control component. The introduction of the fifth control valve 23 enables the liquid outlet end of the infusion pipeline 42 to be flexibly connected to the feed pipeline 21 through the fifth control valve 23, thereby constructing a recovery and reuse path for the leaked liquid.

[0041] When the dosing pump 20 leaks, the leaked liquid is first collected by the collection tray 10 and then flows into the leakage liquid collection box 40. At this time, the control component will receive a signal from the liquid level measuring component 50 and, based on the preset logic, determine whether it is necessary to start the recycling and reuse process. If the judgment result is that recycling and reuse are required, the control component will immediately send an instruction to the fifth control valve 23 to open it. In this way, the leaked liquid in the infusion pipeline 42 can flow into the feed pipeline 21 through the fifth control valve 23 and eventually enter the dosing pump 20 again, completing the recycling and reuse cycle. This design not only reduces the waste of raw materials and reduces production costs, but also improves the environmental friendliness of the entire production process. At the same time, the electrical connection between the fifth control valve 23 and the control component ensures the high degree of automation and intelligence of the entire recycling and reuse process, thereby improving production efficiency and safety.

[0042] Furthermore, there are multiple dosing pumps 20, that is, the leakage collection alarm device of the dosing pump 20 can support the simultaneous operation of multiple dosing pumps 20, and the feed ends of the multiple dosing pumps 20 are installed in parallel on the feed pipeline 21. This design ensures that each dosing pump 20 can obtain raw materials from the feed pipeline 21 simultaneously and independently without interfering with each other, thereby improving the flexibility and production efficiency of the entire system. The discharge ends of the multiple dosing pumps 20 are all installed with the feed pipeline 22, and the multiple feed pipelines 22 The calibration columns 30 are installed in parallel on the above to monitor the operating status of each feed pipeline 22. Once an abnormality occurs in a feed pipeline 22, such as leakage, the calibration column 30 will immediately send an abnormal signal to the control component, and the control component will respond quickly and start the corresponding alarm and processing procedures. One end of the breathing tube 44 is connected to the downstream end of any one of the calibration columns 30, ensuring the pressure balance in the leakage liquid collection box 40 and preventing liquid leakage or backflow problems caused by pressure differences.

[0043] In order to further improve the flexibility and control accuracy of the system, the feed ends of the multiple dosing pumps 20 are provided with a fifth control valve 23, and the fifth control valve 23 is installed on the feed pipeline 21, so that the feed of each dosing pump 20 can be independently controlled, and the liquid outlet end of the infusion pipeline 42 can be connected to the feed pipeline 21 through any one of the fifth control valves 23. The fifth control valve 23 is electrically connected to the control component. Once the system detects a leak, the control component will quickly analyze the leakage and control the fifth control valve 23 connected to the liquid outlet end of the infusion pipeline 42 to open, so as to realize the rapid recovery of the leaked liquid. This automated control method greatly improves the response speed and processing efficiency of the system.

[0044] Furthermore, the fifth control valve 23 connected to the infusion pipeline 42 is a pneumatic three-way ball valve. Through the electrical connection with the control component, the pneumatic three-way ball valve can accurately execute the instructions of the control component, realize the rapid recovery and reuse of the leaked liquid, and improve the safety and environmental protection of the entire system.

[0045] A fourth control valve 221 is installed on the material delivery pipeline 22. The fourth control valve 221 is arranged at the discharge end of the material delivery pipeline 22. The fourth control valve 221 is electrically connected to the control component. The introduction of the fourth control valve 221 enables the control component to directly control the on-off of the material delivery pipeline 22, that is, when the control component receives an abnormal signal, it will quickly determine whether it is necessary to close the material delivery pipeline 22 to prevent further spread of the leaked liquid. At this time, the control component will send an instruction to the fourth control valve 221 to achieve emergency closure and cut off the circulation of the material delivery pipeline 22. This design greatly improves the safety and reliability of the leakage collection and alarm device of the entire dosing pump 20.

[0046] The collecting tray 10 is provided with a leakage liquid collecting hole 11 , which is in communication with the collecting pipe 41 , so that the leaked liquid can quickly flow into the collecting pipe 41 through the collecting hole.

[0047] The liquid level measuring element 50 is a magnetic flap level gauge, which uses the principle of magnetic float to indicate the height of the liquid level by flipping the magnetic flap. It not only has clear readings but also has high reliability and stability.

[0048] The magnetic flap level gauge can be used to understand the liquid level in the leakage liquid collection box 40 in real time. Once the liquid level exceeds the preset safety range, the liquid level alarm module will immediately send out an alarm signal to ensure that the leakage problem can be discovered and handled in time.

[0049] This design not only improves production safety, but also reduces maintenance costs.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
