Description

Technical Field

[0001] This utility model belongs to the field of industrial liquid technology, specifically relating to a defoaming detection device for rust-preventive cutting fluid. Background Technology

[0002] Cutting fluid is used for cooling, lubrication and rust prevention in machining, but it is prone to foaming during stirring or spraying, which leads to reduced cooling effect, increased equipment corrosion and reduced machining accuracy.

[0003] Rust-preventive cutting fluids need to undergo defoaming treatment after production, followed by sampling and testing. However, the existing testing procedures are complex and require the use of multiple independent instruments (such as vacuum pumps, pressure gauges, and thermometers). This process is cumbersome and inefficient, and defoaming performance can only be assessed visually or through simple timing. There is a lack of simultaneous monitoring of parameters such as temperature and pressure. Utility Model Content

[0004] The purpose of this invention is to provide a rust-preventive cutting fluid defoaming detection device, comprising: The box is hollow inside and has four casters installed at the bottom; The vacuum pump is fixedly installed inside the housing, and the suction port is connected to a vacuum tube. The vacuum chamber is fixed to the upper surface of the box, and a manual valve is installed on the side wall. The manual valve is connected to the vacuum tube through a quick-release flange clamp.

[0005] Preferably, a sealed top cover is installed on the top of the vacuum chamber via a chamber cover hinge, a chamber hinge, and a hinge shaft, and an observation window is embedded in the center of the sealed top cover.

[0006] Preferably, the side wall of the vacuum chamber also includes electrodes, needle valves, and temperature sensors, and the electrodes, needle valves, and temperature sensors are all connected to the vacuum chamber via flanges.

[0007] Preferably, it also includes a vacuum gauge and a negative pressure valve, both of which are fixed to the joint extending from the side wall of the vacuum chamber by the quick-release flange clamp.

[0008] Preferably, the surface of the housing is provided with a display screen, a detection button, and a vacuum pump button.

[0009] The beneficial effects of this utility model are: Through integrated design, the vacuum level, temperature and conductivity data of the rust-preventive cutting fluid can be collected simultaneously during the vacuuming process, and the foam status can be monitored in real time to ensure the accuracy of the test results.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figures 1 to 3 As shown, this embodiment provides a rust-preventive cutting fluid defoaming detection device, including: The housing 1 is hollow inside and has four casters 2 installed at the bottom for support and movement; the vacuum pump 3 is fixedly installed inside the housing 1 and the suction port is connected to the vacuum tube 4; the vacuum chamber 5 is fixed to the upper surface of the housing 1 and has a manual valve 6 installed on the side wall. The manual valve 6 is connected to the vacuum tube 4 through a quick-release flange clamp 7 to achieve a sealed fixation.

[0017] The vacuum chamber 5 is topped with a sealed top cover 8 via a chamber cover hinge, a chamber hinge, and a hinge shaft. The hinge is fastened to the chamber with bolts. An observation window 9 is embedded in the center of the sealed top cover 8 to visually observe the defoaming of the rust-preventive cutting fluid. When the top cover is closed, a silicone pressure-sealing strip on the inner side of the sealed top cover 8 adheres to the edge of the chamber, ensuring the vacuum chamber remains airtight under vacuum pressure.

[0018] The side wall of the vacuum chamber 5 also includes an electrode 10, a needle valve 11, and a temperature sensor 12. The electrode 10, needle valve 11, and temperature sensor 12 are all connected to the vacuum chamber 5 via flanges 13. The electrode 10 is connected to the side wall of the vacuum chamber via a 304 stainless steel flange 13, with a PTFE gasket between the flange 13 and the chamber to prevent electrochemical corrosion. The end of the electrode 10 extends into the liquid inside the chamber to detect the conductivity of the cutting fluid. The needle valve 11 is connected to the side wall of the chamber via an NPT threaded connector and the 304 stainless steel flange 13. The outlet end of the needle valve 11 is connected to a silicone hose to control the injection of liquid or the release of gas from the chamber. The temperature sensor is a PT100 platinum resistance sensor, which passes through a threaded sealing connector through a blind plate on the surface of the flange 13, allowing the sensor probe to extend into the chamber to monitor the liquid temperature in real time. The electrode 10, needle valve 11, and temperature sensor 12 are all connected to the chamber via independent channels, ensuring independent data acquisition without interference.

[0019] It also includes a vacuum gauge 14 and a negative pressure valve 15. The vacuum gauge 14 is fixed to the KF vacuum connector extending from the side wall of the vacuum chamber 5 via a quick-release flange clamp 7. A metal bellows is installed between the vacuum gauge 14 and the connector to absorb vibration. The negative pressure valve 15 is connected to the side wall of the chamber via a compression fitting. The outlet end of the negative pressure valve 15 is connected to a stainless steel exhaust pipe for adjusting the vacuum level inside the chamber. The vacuum gauge 14 monitors the pressure inside the chamber in real time and adjusts the vacuum level by opening and closing the negative pressure valve 15 to ensure that the pressure remains stable at the set value during the testing process. The surface of the housing 1 is equipped with a display screen 16, a detection button, and a vacuum pump button. The display screen 16 is connected to the data acquisition module of the vacuum gauge 14, temperature sensor 12, and electrode 10 via an RS485 interface, displaying the vacuum level, temperature, conductivity, and detection time in real time. Pressing the detection button triggers the PLC controller to start the detection process, including data recording and result analysis, and adjusts it according to a preset range. The vacuum pump button is used to independently control the start and stop of the vacuum pump. Combined with the observation window 9 for visual inspection of defoaming and the real-time data on the display screen 16, it allows for more accurate judgment of the subtle defoaming state of the rust-preventive cutting fluid.

[0020] During operation, it is important to note that the vacuum chamber 5 has a liquid level line. This line must be lower than the connection point between the manual valve 6 and the vacuum chamber 5. The portion of the needle valve 11 extending into the vacuum chamber 5 must have a hose that contacts the bottom of the chamber to ensure complete liquid injection and extraction. Before testing, inject rust-preventive cutting fluid into the chamber through the needle valve 11 up to the liquid level mark. After closing the needle valve 11, start the vacuum pump 3 to prevent liquid from flowing back through the needle valve 11 or being extracted by the vacuum pump 3. After testing, slowly drain the liquid through the needle valve 11 to prevent sudden pressure changes inside the chamber from causing liquid splashing.
