Description

Technical Field

[0001] This invention belongs to the technical field of oil measuring devices, and more specifically, relates to an infrared spectrophotometric oil measuring device for oil mist detection. Background Technology

[0002] In the field of oil mist detection, traditional oil mist testing devices have a series of problems that seriously affect detection capabilities, ease of equipment maintenance, and the comprehensiveness and accuracy of measurements.

[0003] Heat dissipation and detection efficiency issues

[0004] Heat dissipation difficulties: Traditional oil testing devices, especially those using infrared spectrophotometers, generate a significant amount of heat during operation. However, traditional devices often lack effective heat dissipation measures, leading to excessively high internal temperatures. This affects the performance stability of the infrared spectrophotometers, thereby reducing detection accuracy and reliability. High temperatures can also shorten the lifespan of the components and increase equipment maintenance costs.

[0005] Low detection efficiency: Traditional oil mist detection devices rely on a passive approach to absorption and detection, failing to actively increase the contact area and duration between the infrared spectrophotometer and the oil mist. This results in a slow detection process, making it difficult to quickly and accurately detect parameters such as oil mist concentration. Consequently, they cannot meet the demands of scenarios requiring high detection efficiency, such as real-time monitoring in industrial production sites.

[0006] Equipment maintenance issues

[0007] The traditional oil testing device has an unreasonable structural design, resulting in significant maintenance difficulties. For example, repairing vulnerable components such as the internal fan assembly often requires disassembling numerous other parts, making the process cumbersome and time-consuming. This not only increases equipment downtime and affects production efficiency but also raises maintenance costs and reduces the maintainability and usability of the equipment.

[0008] Measurement range and accuracy issues

[0009] Fixed installation limitations: Traditional oil mist testing devices are typically fixed in a specific location, with no flexibility in adjusting height and angle. However, in real-world applications, oil mist distribution may be uneven, and the concentration and characteristics of oil mist may differ at different locations. Fixed-installation oil mist testing devices cannot comprehensively cover various oil mist distribution conditions, resulting in a limited measurement range and difficulty in obtaining accurate oil mist information.

[0010] Poor adaptability: Because the measurement position and angle cannot be adjusted according to actual conditions, traditional oil mist measuring devices are poorly adaptable to complex environments and diverse oil mist distributions. When faced with oil mist of different shapes and sizes, as well as different flow states, it is difficult to guarantee the accuracy and comprehensiveness of the measurement, and it cannot meet the high-precision and comprehensive requirements of modern industry for oil mist detection. Summary of the Invention

[0011] To address the aforementioned technical problems, this invention provides an infrared spectrophotometer for oil mist detection, which solves the significant shortcomings of existing oil mist detection technologies in terms of heat dissipation and detection efficiency, equipment maintenance, and measurement range and accuracy, thus failing to meet the needs of modern industrial production, environmental protection, and other fields for efficient, accurate, and comprehensive oil mist detection.

[0012] An infrared spectrophotometer for oil mist detection includes an oil measuring device body, a lateral air inlet on the side wall of the oil measuring device body, a drive fan blade assembly inside the oil measuring device body, four sets of fan assemblies on the rear side wall of the drive fan blade assembly, an upper exhaust port on the top of the oil measuring device body, a support base below the oil measuring device body, a retractable upper drive rod inside the support base, a support disc on the top of the upper drive rod, a cross-shaped fixing bracket above the support disc, and the cross-shaped fixing bracket connected to the bottom of the oil measuring device body.

[0013] Preferably, the side air inlet is located in the lower half of the oil testing device body, and the drive fan blade assembly inside the oil testing device body is located in front of the side air inlet. A temperature sensor is fixedly installed at the front end of the drive fan blade assembly, and four rear drive rods are fixedly installed at the rear end of the drive fan blade assembly. Each fan assembly is connected to a rear drive rod, and a motor for driving the fan assembly is provided at the end of each rear drive rod. All four ends of the drive fan blade assembly are movably engaged with ring-shaped clips. The side air inlet on the side of the oil testing device body and the top exhaust port are combined to form an L-shaped air duct. Multiple infrared spectrophotometers are installed inside the oil testing device body, and each assembly is located above the drive fan blade assembly.

[0014] Preferably, a cross base is fixedly installed at the bottom of the support base, a drive assembly is fixedly installed at the bottom inside the support base, an upper drive rod is threaded onto the drive assembly, a steering assembly is installed between the top of the upper drive rod and the support disc, and side fixing wings are fixedly installed at both ends of the cross fixing frame, and the two side fixing wings are used to improve the support force on the body of the oil measuring device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, multiple drive fan blade assemblies are fixed on the same horizontal fixing rod, and the horizontal fixing rod is fixedly connected to the inner wall of the oil testing device body. After the multiple drive fan blade assemblies are started, they quickly draw air from outside the oil testing device body. The air enters through the side air inlet, and the side air inlet and the upper air outlet form an L-shaped cavity inside the oil testing device body. Therefore, the air drawn in by the drive fan blade assemblies will flow upward along the oil testing device body. The air rapidly cools down the multiple infrared spectrophotometric oil testing assemblies. At the same time, the start of the drive fan blade assemblies can absorb external oil mist into the oil testing device body, increasing the contact area and duration between the infrared spectrophotometric oil testing assemblies and the oil mist, thereby further improving the ability to detect oil mist.

[0017] In this invention, the user can remove the ring-shaped clip and then repair the fan assembly, thereby improving the convenience of maintenance. At the same time, at least two hollow holes are opened through the surface of the drive fan blade assembly. Multiple hollow holes can reduce the overall weight of the drive fan blade assembly and increase the range of air circulation. The temperature sensor at the front end of the drive fan blade assembly has a temperature measurement function and can adjust the speed of multiple fan assemblies according to the real-time temperature, thereby keeping the oil measuring device body in the optimal state.

[0018] In this invention, the user can activate the drive assembly inside the support base. The threaded rod at the end of the drive assembly rotates inside the upper drive rod, simultaneously driving the upper drive rod to move up or down. The movement of the upper drive rod drives the oil measuring device body to rise and fall via the support disc. After the oil measuring device body rises and falls, the angle can be adjusted as needed. The oil measuring device body and the upper drive rod are adjusted via a steering assembly. The side fixing wings on both sides of the cross-shaped fixing frame provide additional support for the oil measuring device body. By setting the oil measuring device body to be adjustable in height and angle, more comprehensive oil mist measurement can be achieved, improving the measurement range and accuracy.

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0027] Please see Figures 1-6 This invention provides an infrared spectrophotometer for oil mist detection, comprising an oil mist detection device body 1, a lateral air inlet 14 on the side wall of the oil mist detection device body 1, a drive fan blade assembly 3 inside the oil mist detection device body 1, and four sets of fan assemblies 17 on the rear side wall of the drive fan blade assembly 3, an upper exhaust vent 11 on the top of the oil mist detection device body 1, and a support base 21 below the oil mist detection device body 1. A retractable upper drive rod 23 is installed inside the support base 21, and a support disc 24 is installed on the top of the upper drive rod 23 to quickly dissipate air from the outside of the oil mist detection device body 1. Air is drawn in through the side air inlet 14. The side air inlet 14 and the upper exhaust vent 11 form an L-shaped cavity inside the oil measuring device body 1. Therefore, the air drawn in by the drive fan blade assembly 3 will flow upward along the oil measuring device body 1. The air rapidly cools down the multiple infrared spectrophotometric oil measuring components. At the same time, the start of the drive fan blade assembly 3 can absorb external oil mist into the oil measuring device body 1, increasing the contact area and duration between the infrared spectrophotometric oil measuring components and the oil mist. A cross-shaped fixing bracket 27 is provided above the support disc 24. The cross-shaped fixing bracket 27 is connected to the bottom of the oil measuring device body 1.

[0028] The side air inlet 14 is located in the lower half of the oil testing device body 1, and the drive fan blade assembly 3 inside the oil testing device body 1 is located in front of the side air inlet 14. A temperature sensor 15 is fixedly installed at the front end of the drive fan blade assembly 3, and four rear drive rods 16 are fixedly installed at the rear end of the drive fan blade assembly 3. Each fan assembly 17 is connected to a rear drive rod 16, and a motor for driving the fan assembly 17 is provided at the end of each rear drive rod 16. Ring clips 19 are movably engaged at the four ends of the drive fan blade assembly 3. The user can pull out the ring clips 19 and then adjust the fan assembly 17. 7. Maintenance can be carried out to improve the convenience of maintenance. At the same time, at least two hollow holes 18 are opened through the surface of the drive fan blade assembly 3. Multiple hollow holes 18 can reduce the overall weight of the drive fan blade assembly 3 and improve the air circulation range. The temperature sensor 15 at the front end of the drive fan blade assembly 3 has a temperature measurement function. According to the real-time temperature, the side air inlet 14 on the side of the oil measuring device body 1 and the top air outlet 11 are combined to form an L-shaped air duct. Multiple infrared spectrophotometers are installed inside the oil measuring device body 1, and each component is located above the drive fan blade assembly 3.

[0029] A cross base 2 is fixedly installed at the bottom of the support base 21. A drive assembly 22 is fixedly installed inside the bottom of the support base 21. The user can start the drive assembly 22 inside the support base 21. The threaded rod at the end of the drive assembly 22 rotates inside the upper drive rod 23, which drives the upper drive rod 23 to move up or down. The movement of the upper drive rod 23 drives the oil measuring device body 1 to rise and fall through the support disc 24. After the oil measuring device body 1 rises and falls, the angle can be adjusted as needed. The oil measuring device body 1 and the upper drive rod 23 are adjusted through the steering assembly 25. The side fixing wings 28 on both sides of the cross fixing frame 27 provide additional support for the oil measuring device body 1. The upper drive rod 23 is threaded onto the drive assembly 22. The steering assembly 25 is installed between the top of the upper drive rod 23 and the support disc 24. The two ends of the cross fixing frame 27 are fixedly installed with side fixing wings 28, and the two side fixing wings 28 are used to increase the support force on the oil measuring device body 1.

[0030] Working principle:

[0031] The first step involves activating multiple infrared spectrophotometric oil detection components inside the oil detection device body 1 during oil mist detection. Subsequently, multiple drive fan blade assemblies 3 inside the oil detection device body 1 are activated. These drive fan blade assemblies 3 are fixed to the same horizontal fixing rod 13, which is fixedly connected to the inner wall of the oil detection device body 1. After activation, the drive fan blade assemblies 3 rapidly draw in air from outside the oil detection device body 1. The air enters through the side air inlet 14, which, along with the upper exhaust outlet 11, forms an L-shaped cavity within the oil detection device body 1. Therefore, the air drawn in by the drive fan blade assemblies 3 flows upwards along the oil detection device body 1, rapidly cooling the multiple infrared spectrophotometric oil detection components. Simultaneously, the activation of the drive fan blade assemblies 3 absorbs external oil mist into the oil detection device body 1, increasing the contact area and duration between the infrared spectrophotometric oil detection components and the oil mist, thereby further enhancing the oil mist detection capability.

[0032] When the multiple fan assemblies 17 on the back of the drive fan blade assembly 3 are damaged, the user can pull out the ring clip 19 and then repair the fan assembly 17, thereby improving the convenience of maintenance. At the same time, at least two hollow holes 18 are opened through the surface of the drive fan blade assembly 3. Multiple hollow holes 18 can reduce the overall weight of the drive fan blade assembly 3 and improve the air circulation range. The temperature sensor 15 at the front end of the drive fan blade assembly 3 has a temperature measurement function and can adjust the speed of the multiple fan assemblies 17 according to the real-time temperature, thereby keeping the oil measuring device body 1 in the optimal state.

[0033] In the second step, when the oil mist is detected by the oil measuring device body 1, the user can activate the drive component 22 inside the support base 21. The threaded rod at the end of the drive component 22 rotates inside the upper drive rod 23, which in turn moves the upper drive rod 23 up or down. The movement of the upper drive rod 23 drives the oil measuring device body 1 to rise and fall through the support disc 24. After the oil measuring device body 1 rises and falls, the angle can be adjusted as needed. The oil measuring device body 1 and the upper drive rod 23 are adjusted through the steering component 25. The side fixing wings 28 on both sides of the cross fixing frame 27 provide additional support for the oil measuring device body 1. By setting the oil measuring device body 1 to be adjustable in height and angle, the oil mist measurement can be more comprehensively realized, improving the measurement range and accuracy.
