The controller can be a PLC controller, and the host computer can be a computer or a control device with a touch screen function. The diaphragm pump 1, the centrifugal sieve filter 2, the liquid concentration meter 3 and the circulation detection tank 4 are connected in sequence by pipelines. The diaphragm pump 1 is provided with a raw liquid inlet pipe 12, and the circulation detection tank 4 is provided with a filtered liquid outlet pipe 11 connected to the inside thereof. At least a pH meter 5, a dissolved oxygen meter 6 and a conductivity meter 7 electrically connected to the controller are provided in the circulation detection tank 4, and other detectors can be provided according to usage requirements.

[0018] When the above-mentioned detection device is in use, the original liquid inlet pipe 12 is connected to the cutting fluid supply tank, and the filtered liquid outlet pipe 11 is connected to the machine tool liquid supply system. During operation, the diaphragm pump 1 automatically extracts the cutting fluid original liquid from the cutting fluid supply tank, and after mixing and filtering through the centrifugal rotary screen filter 2, it flows along the pipeline through the liquid concentration meter 3 for concentration detection, and then enters the circulation detection pool 4 for pH value, oxygen content, and conductivity detection, and then flows into the machine tool liquid supply system along the filtered liquid outlet pipe 11. Among them, the operation of the diaphragm pump 1 and the centrifugal rotary screen filter 2 is controlled by the controller, and each detection parameter is displayed in real time by the host computer.

[0019] The above method realizes the automatic detection of cutting fluid quality, reduces the input of manual labor, and effectively improves work efficiency. Through the setting of liquid concentration meter 3, pH meter 5, dissolved oxygen meter 6 and conductivity meter 7, the detection of various parameters of cutting fluid can be realized, which is conducive to accurately controlling the quality of cutting fluid.

[0020] In this embodiment, the circulation detection pool 4 includes a pool body which is hollow inside and has an opening on the top, and a cover plate for covering the opening of the pool body. The filtered liquid outlet pipe 11 is connected to the bottom side of the pool body, and the bottom of the pool body is inclined at a downward angle of 5°-8° toward the filtered liquid outlet pipe 11. Through this arrangement, the cutting fluid is not prone to deposition.

[0021] In this embodiment, a temperature sensor 8 is further provided in the detection pool. The temperature sensor 8 is electrically connected to the controller and is used to detect the temperature of the cutting fluid.

[0024] Specifically, the connecting pipe 15 at least partially extends into the circulation detection pool 4, and the cleaning assembly also includes extension pipes 10 of the same number as the cleaning nozzles 9. The cleaning nozzles 9 are connected to the extension pipes 10, and the extension pipes 10 are threadedly connected to each other. After the threaded connection, one end of each extension pipe 10 is threadedly connected to the connecting pipe 15, and the other end is threadedly connected to a plug 16.

[0025] When the above-mentioned cleaning component is working, the filtrate outlet pipe 11 is reconnected to the sewage tank, and the cleaning pump 13 pressurizes the tap water and delivers it to each cleaning nozzle 9. Each cleaning nozzle 9 is respectively cleaned and flushed with the pH meter 5, temperature sensor 8, dissolved oxygen meter 6 and conductivity meter 7, and the sewage after flushing flows into the sewage tank.

[0026] In the above method, one end of each extension tube 10 is provided with an internal connecting thread and the other end is provided with an external connecting thread. The internal connecting thread and the external connecting thread of two adjacent extension tubes 10 are connected. Through this arrangement, the subsequent addition and removal of the cleaning nozzle 9 is more convenient and quick.

[0027] In this embodiment, the cover plate is respectively provided with slots for the pH meter 5, the temperature sensor 8, the dissolved oxygen meter 6 and the conductivity meter 7 to be inserted into the circulation detection tank 4. Through the setting of the slots, the pH meter 5, the temperature sensor 8, the dissolved oxygen meter 6 and the conductivity meter 7 are detachably connected to the cover plate.
