Technical Field

[0001] This utility model relates to the field of cutting fluid treatment technology, and in particular to a device for detecting and filtering the pH value and viscosity of cutting fluid. Background Technology

[0002] In machining processes, cutting fluids are widely used to cool and lubricate tools and workpieces to improve machining efficiency and quality. However, cutting fluids gradually deteriorate during use, with changes in their pH and viscosity affecting cutting performance and machine tool life. Furthermore, impurities and chips mixed in the cutting fluid require regular cleaning to prevent clogging and contamination. Currently, cutting fluid testing and filtration are typically performed separately, which is cumbersome and inefficient. Therefore, an integrated device capable of simultaneously testing the pH and viscosity of the cutting fluid and performing filtration is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a dual-mode detection and filtration device for cutting fluid viscosity and pH value, capable of real-time detection of the pH value and viscosity of the cutting fluid, and automatic filtration of the cutting fluid, thereby solving the problems of cumbersome operation, inability to monitor the cutting fluid status in real time, and difficulty in timely handling of abnormal cutting fluid performance in existing technologies. To achieve the above objective, this invention provides a dual-mode detection and filtration device for cutting fluid viscosity and pH value, characterized by comprising: a cutting fluid container for storing filter residue; a pH value detection module installed inside the cutting fluid container for detecting the pH value of the cutting fluid; a viscosity detection module installed inside the cutting fluid container for detecting the viscosity of the cutting fluid; a filtration module installed inside the cutting fluid container for filtering impurities in the cutting fluid; and a control unit connected to the pH value detection module, viscosity detection module, and filtration module for receiving detection data and controlling the working state of the filtration module. The cutting fluid container consists of a cap and a body, which are connected by threads. The body has an inlet near the cap and an outlet near the bottom.

[0004] The pH detection module includes a pH sensor 10 and a signal converter 3. The pH sensor 10 is immersed in the cutting fluid to detect the pH value of the cutting fluid in real time. The signal converter 3 is installed in the middle of the top outer wall of the cutting fluid container to convert the signal detected by the pH sensor 10 into a processable electrical signal.

[0005] The viscosity detection module includes a viscometer and a signal processor 2. The viscometer uses an online viscosity sensor 12 to measure the viscosity of the fluid by means of the vibration frequency of the vibrating element. The signal processor 2 is installed next to the signal converter 3 and is used to process and convert the viscosity signal detected by the viscometer.

[0006] The filtration module includes a filter screen, an oil-absorbing cotton plate 11, and a driving device. The filter screen is a stainless steel filter screen 9, installed inside the cutting fluid container and connected to the inner wall of the cylinder. It has strong corrosion resistance, is not easily corroded, and has a very stable filtration effect, effectively capturing small particles and impurities to ensure the quality of the filtered cutting fluid. The oil-absorbing cotton plate 11 is a detachable oil-absorbing cotton plate made of an oleophilic material, which is easy to replace and clean, and avoids excessive water absorption. The oil-absorbing cotton plate 11 is fixed below the stainless steel filter screen 9. The driving device is installed below the oil-absorbing cotton and connected to the filter screen and the inside of the cylinder. It is used to drive the filter screen to vibrate, preventing impurities from clogging the filter screen and improving filtration efficiency. The driving device is an electromagnetic vibrator 8. By controlling the current frequency of the electromagnetic vibrator 8, the amplitude and frequency of the filter screen vibration can be flexibly changed, thereby improving filtration efficiency.

[0007] The control unit includes a microprocessor 4 and a display screen 1. The microprocessor 4 is used to receive data transmitted by the pH detection module and the viscosity detection module, analyze and process the data, and control the working state of the drive device according to the processing results. The display screen 1 is installed on the outside of the cutting fluid container and is used to display the pH value and viscosity data of the cutting fluid in real time. Beneficial effects

[0008] This utility model's cutting fluid pH and viscosity detection and filtration device has the following advantages: it integrates pH detection, viscosity detection, and filtration functions, enabling simultaneous monitoring and processing of multiple cutting fluid parameters, thus improving work efficiency. Automated control is achieved through the control unit, making operation simple and allowing real-time monitoring of the cutting fluid's condition and timely adjustment of the filtration effect. The filtration module uses a vibrating filter screen, improving filtration efficiency, extending the cutting fluid's service life, and reducing oil pollution to the machine tool environment.

[0013] The present invention will be described in detail below with reference to specific embodiments.

[0014] In this embodiment, the cutting fluid container is a cylindrical storage tank, inside which a pH detection module and a viscosity detection module are installed. The pH sensor 10 of the pH detection module is immersed in the cutting fluid to accurately detect its pH value. The viscosity detection module uses an online viscosity sensor 12, which measures the fluid viscosity by the vibration frequency of a vibrating element. It is designed for long-term stable operation, is robust and durable, and maintains reliability even in harsh industrial environments. It has functions such as temperature compensation and pressure compensation to ensure the accuracy of the measurement results. The filter module is installed below the oil-absorbing cotton and connected to the inside of the cylinder. The filter screen is made of stainless steel and is installed inside the cutting fluid container, connected to the inner wall of the cylinder. It has strong corrosion resistance, is not easily corroded, and has a stable filtration effect, effectively capturing small particles and impurities to ensure the quality of the filtered cutting fluid. The driving device is an electromagnetic vibrator 8. By controlling the current frequency of the electromagnetic vibrator 8, the amplitude and frequency of the filter screen vibration can be flexibly controlled, thereby improving the filtration efficiency.

[0015] The control unit is installed on the outside of the fluid reservoir. The microprocessor 4 receives signals from the pH and viscosity detection modules, determines whether the cutting fluid needs to be replaced or adjusted based on preset thresholds, and controls the operation of the drive unit to optimize the filtration effect. The display screen 1 shows the cutting fluid's pH value, viscosity, and the operating status of the filtration module in real time, facilitating operator monitoring.

[0016] In practical use, the cutting fluid is poured into the storage tank, and the pH and viscosity detection modules begin to operate, monitoring the pH and viscosity of the cutting fluid in real time. The control unit determines the state of the cutting fluid based on the detection data and controls the operation of the filtration module. The filtration module filters the cutting fluid, removing oil and shavings to ensure its cleanliness. This invention's cutting fluid pH and viscosity detection and filtration device has a simple structure, is easy to operate, and effectively improves the efficiency of cutting fluid use and the maintenance effect of machine tools.
