Pressure relief is provided by a one-way pressure relief valve 8. The pressure relief pipeline 9 is used to divert the flow to avoid excessive flow, which could cause the filter components to burst. This avoids personal injury caused by media splashing, ensures the normal operation of the optical lens polishing liquid circulation filter, improves the safety of equipment use, and avoids pump and valve fatigue failure caused by frequent overpressure impacts, reduces equipment corrosion rate, and extends the service life of the polishing liquid circulation filter.

[0020] Please see Figures 1-3 In this embodiment, the filter module 4 and the storage tank 3 are connected to each other through the connecting pipe 15. The lower end of the self-priming pump 6 is fixedly connected to the mounting base 1. The one-way pressure relief valve 8 is electrically connected to the hydraulic sensor 7. The end of the pressure relief pipe 9 away from the one-way pressure relief valve 8 is fixedly connected to the collection tank 2. The upper end of the collection tank 2 is fixedly installed with the liquid inlet 16. The upper side of the storage tank 3 is fixedly installed with the external conduit 17. The device is equipped with a device terminal, which can receive and process the detection data transmitted by the sensor and control the operation of each drive structure according to the set program. The collection tank 2 can collect the polishing liquid used in the process (it can be connected to the optical lens polishing equipment). The self-priming pump 6 can drive the polishing liquid to circulate (the self-priming pump 6 can be set as a drive component with similar functions). The filter module 4 can filter the polishing liquid used in the process. The storage tank 3 can store the filtered polishing liquid. The hydraulic sensor 7 can monitor the hydraulic pressure inside the filter structure pipe in real time. The one-way pressure relief valve 8 can perform pressure relief protection and cooperate with the pressure relief pipe 9 to complete the diversion and discharge it back into the collection tank 2.

[0021] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, a temperature sensor 18 is fixedly installed at the front end of the temperature control heating module 10, and a detection rod 19 is fixedly installed at the left end of the temperature sensor 18. A detection head 20 is fixedly installed at the left end of the detection rod 19, extending into the interior of the storage tank 3. The temperature control heating module 10 is electrically connected to the temperature sensor 18. The output end of the drive motor 12 is rotatably connected to the storage tank 3. The drive motor 12 drives the transmission shaft 13 to rotate. The stirring rods 14 are evenly spaced, and anti-sedimentation blades 22 are fixedly installed at the lower end of the transmission shaft 13. A transparent liquid level observation plate 21 is fixedly installed at the front end of the storage tank 3. The temperature control heating module 10 can control... Heating rod 11 heats the polishing liquid at a constant temperature (heating rod 11 has a heating wire inside), temperature sensor 18 can detect the liquid temperature to ensure that the polishing liquid is controlled within a suitable temperature range, drive motor 12 can drive transmission shaft 13 to rotate (drive motor 12 can be set as a drive component with similar function), stirring rod 14 and anti-settling blade 22 can evenly stir the polishing liquid (drive motor 12 can control the rotation direction of anti-settling blade 22 to ensure the formation of an upward liquid flow), better maintain the constant temperature of the polishing liquid and prevent the polishing liquid from settling and stratifying, and transparent liquid level observation plate 21 is used to observe the internal state of the liquid storage tank 3.

[0022] During operation, the polishing liquid used in the process is collected by the collection tank 2 and circulated by the self-priming pump 6, which then filters it through the filter module 4 and sends it to the storage tank 3 for storage. During this process, the hydraulic sensor 7 monitors the hydraulic pressure inside the filter structure pipe in real time, and when the detected set value is reached, the one-way pressure relief valve 8 provides pressure relief protection. The pressure relief pipe 9 completes the diversion and discharges the liquid back into the collection tank 2. The temperature control heating module 10 controls the heating rod 11 to heat the polishing liquid at a constant temperature. The temperature sensor 18 detects the liquid temperature to ensure that the polishing liquid is controlled within a suitable temperature range. The drive motor 12 drives the transmission shaft 13 to rotate, which makes the stirring rod 14 and the anti-settling blades 22 stir the polishing liquid evenly, better maintain the constant temperature of the polishing liquid, and prevent the polishing liquid from settling and separating.

[0023] Through the above steps, the hydraulic sensor 7 monitors the hydraulic pressure inside the filter structure pipeline in real time, and the one-way pressure relief valve 8 provides pressure relief protection. This, combined with the pressure relief pipeline 9, diverts the flow, preventing excessive flow that could cause the filter components to burst. This also avoids personal injury caused by media splashing, ensuring the normal operation of the optical lens polishing fluid circulation filter and improving equipment safety. Simultaneously, it avoids fatigue failure of the pump body and valves caused by frequent overpressure impacts, reduces equipment corrosion, and extends the service life of the polishing fluid circulation filter. This addresses the problem that excessive flow during operation of the optical lens polishing fluid circulation filter could lead to filter component bursting and affect the normal operation of the device.
