Description

Technical Field

[0001] This utility model relates to the field of defoaming device technology, and in particular to an oil monitoring and defoaming device. Background Technology

[0002] In industrial production, oil serves as a crucial lubricating and transmission medium for various mechanical equipment, and its condition directly impacts the equipment's operational stability and lifespan. The presence of air bubbles in the oil can lead to accelerated equipment wear and reduced transmission efficiency. Therefore, monitoring the oil and promptly identifying impurities such as air bubbles is essential, making oil monitoring and defoaming devices a key component in ensuring the normal operation of equipment.

[0003] Currently, there are devices on the market that integrate oil monitoring and defoaming in the same chamber. Typically, the oil in the chamber is first stirred and defoamed using a stirring component, and then the monitoring component is used to directly monitor the defoamed oil.

[0004] However, existing oil monitoring and defoaming devices have shortcomings in defoaming. Defoaming and monitoring are in the same chamber, and the disturbance caused by stirring can easily cause the oil that has just been defoamed to mix with air bubbles again, affecting the accuracy of monitoring. The stirred oil will flow in the oil tank, and the speed of air bubble removal is slow in this process. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an oil monitoring defoaming device, which aims to improve the problems of slow defoaming speed and the impact of stirring defoaming on monitoring results in traditional oil monitoring defoaming devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oil monitoring and defoaming device, comprising an oil tank, a monitoring tank fixedly connected to the lower surface of the oil tank, an oil tank lid attached to the upper surface of the oil tank, a fixed box fixedly connected to the upper surface of the oil tank lid, and a rotating component disposed inside the fixed box;

[0007] The rotating assembly includes a motor, the outer wall of which is fixedly connected to the inner wall of the fixed box. A rotating shaft is fixedly connected to the output end of the motor. A stirring paddle is fixedly connected to one end of the rotating shaft. The stirring paddle is rotatably connected to the inside of the oil tank. A guide plate is attached to the inner wall of the oil tank. An intercepting net is attached to the outer wall of the guide plate. A partition is attached to the lower surface of the intercepting net. The outer wall of the partition is fixedly connected to the inner wall of the monitoring tank. A laser emitter is fixedly connected to the inner wall of the monitoring tank. A temperature sensor is fixedly connected to the inner wall of the monitoring tank. The laser emitter and the temperature sensor are symmetrical.

[0008] Furthermore, an L-shaped groove is formed on the inner wall of the oil tank, and a slider is slidably connected to the inner wall of the L-shaped groove. A limit wire is threadedly connected inside the slider, and the outer wall of the limit wire is threadedly connected to a circular groove inside the oil tank.

[0009] Furthermore, the lower surface of the slider is fixedly connected to the outer wall of the interception net, and the outer wall of the interception net is slidably connected to the inner wall of the oil tank.

[0010] Furthermore, the upper surface of the guide plate is positioned below the exhaust port.

[0011] Furthermore, a photoelectric receiver is fixedly connected to the inner wall of the monitoring barrel, and an oil outlet pipe is fixedly connected to the outer wall of the monitoring barrel.

[0012] Furthermore, the oil tank is provided with an exhaust port inside.

[0013] Furthermore, the guide plate is internally threaded with a nut, and the outer wall of the nut is threadedly connected to the inner wall of the oil tank.

[0014] Furthermore, an oil inlet pipe is fixedly connected to the upper surface of the oil drum cover.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the oil is stirred by a driving motor and the oil is guided by a guide plate to accelerate the defoaming speed. The stirred bubbles are discharged from the vent hole, which increases the efficiency. The oil tank and the monitoring tank are separated by a partition. The treated oil enters the monitoring area for monitoring through the filter holes of the partition. The partition separates the oil defoaming and oil monitoring work areas to prevent the oil from flowing around during stirring and affecting the monitoring results.

[0017] 2. In this utility model, by adding an intercepting mesh to the inner wall of the oil tank, it is prevented that air bubbles that have not completely overflowed after stirring will enter the monitoring tank, thus ensuring the accuracy of the monitoring results. During stirring, the air bubbles on the surface of the intercepting mesh will float upward along the mesh surface to the top of the upper cavity and re-enter the exhaust process. By adding L-shaped grooves on both sides of the inner wall of the oil tank, the slider drives the intercepting mesh to slide in the L-shaped groove, making it easy to remove the intercepting mesh for cleaning. The intercepting mesh is fixed by the limiting screw inside the slider, locking the intercepting mesh in the circular groove of the inner wall of the oil tank to avoid blockage after long-term use and ensure smooth oil flow.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 An embodiment of this utility model is provided: an oil monitoring and defoaming device, including an oil tank 1 for containing oil, a defoaming device for defoaming the oil, a monitoring tank 15 fixedly connected to the lower surface of the oil tank 1 for optical monitoring of the defoamed oil, an oil tank lid 2 attached to the upper surface of the oil tank 1 to prevent the oil from splashing out during stirring and causing waste, and to prevent impurities from entering the oil tank 1 and contaminating the oil quality, and a fixed box 4 fixedly connected to the upper surface of the oil tank lid 2 to provide installation space for the motor 10, and a rotating component is provided inside the fixed box 4;

[0028] The rotating assembly includes a motor 10, which provides rotational power for stirring and defoaming. The outer wall of the motor 10 is fixedly connected to the inner wall of the fixed box 4. A rotating shaft 11 is fixedly connected to the output end of the motor 10. A stirring paddle 12 is fixedly connected to one end of the rotating shaft 11. The rotating shaft 11 is used to transmit power from the motor 10 and drive the stirring paddle 12 to rotate. The stirring paddle 12 stirs the oil in the oil tank 1 to achieve defoaming by rotating. The stirring paddle 12 is rotatably connected inside the oil tank 1. A guide plate 7 is attached to the inner wall of the oil tank 1. The guide plate 7 guides the oil to flow upward to promote the rise of bubbles. An intercepting net 13 is attached to the outer wall of the guide plate 7. To prevent tiny air bubbles that have not overflowed from entering the monitoring tank 15 and affecting the monitoring results, a partition 14 is attached to the lower surface of the interception net 13. The partition 14 separates the oil tank 1 from the monitoring tank 15, allowing the treated oil to flow into the monitoring tank 15. The outer wall of the partition 14 is fixedly connected to the inner wall of the monitoring tank 15. A laser emitter 16 is fixedly connected to the inner wall of the monitoring tank 15. The laser emitter 16 emits laser light for optical monitoring of the oil. A photoelectric receiver 18 is fixedly connected to the inner wall of the monitoring tank 15 to receive the laser signal to complete the optical monitoring of the oil. The laser emitter 16 and the photoelectric receiver 18 are symmetrical.

[0029] Specifically, the motor 10 first drives the rotating shaft 11 to rotate, which in turn drives the stirring paddle 12 to rotate, stirring and defoaming the oil in the oil tank 1. Then, the oil flows upward along the guide plate 7, and the bubbles rise with it and are discharged through the vent 5. The tiny bubbles that do not escape are blocked by the interception net 13. After that, the treated oil flows into the monitoring tank 15 through the partition 14. The laser emitter 16 emits a laser, and the photoelectric receiver 18 receives the laser signal, thereby completing the optical monitoring of the oil. At the same time, the temperature sensor 17 is used to correct the monitoring error and ensure the accuracy of the monitoring.

[0030] Reference Figures 4-6An L-shaped groove 9 is formed on the inner wall of the oil tank 1. A slider 19 is slidably connected to the inner wall of the L-shaped groove 9. The L-shaped groove 9 provides a sliding track and positioning space for the slider 19. A limit screw 20 is threaded inside the slider 19 to lock the position of the slider 19 and fix the intercepting net 13. The outer wall of the limit screw 20 is threaded into a circular groove inside the oil tank 1. The lower surface of the slider 19 is fixedly connected to the outer wall of the intercepting net 13. The outer wall of the intercepting net 13 is slidably connected to the inner wall of the oil tank 1. The output end of the motor 10 is rotatably connected to the inner wall of the oil tank cover 2. The upper surface of the guide plate 7 is set at the outlet. Below the vent 5, a temperature sensor 17 is fixedly connected to the inner wall of the monitoring tank 15 to collect oil temperature data to correct optical monitoring errors. An oil outlet pipe 6 is fixedly connected to the outer wall of the monitoring tank 15 to discharge the monitored oil. An vent 5 is opened inside the oil tank 1 to discharge the air bubbles floating in the oil. A nut 8 is threaded inside the guide plate 7 to fix the guide plate 7 to the inner wall of the oil tank 1. The outer wall of the nut 8 is threaded to the inner wall of the oil tank 1. An oil inlet pipe 3 is fixedly connected to the upper surface of the oil tank cover 2 to inject the oil to be treated into the oil tank 1.

[0031] Specifically, by sliding the slider 19, it moves along the L-shaped groove 9, causing the interceptor net 13 to adjust its position. When the slider 19 moves to the appropriate position, the limit screw 20 is turned to lock the slider 19, thereby fixing the interceptor net 13 and preventing incomplete overflow of air bubbles after stirring from entering the monitoring tank 15, thus ensuring the accuracy of the monitoring results.

[0032] Working principle: When the oil monitoring and defoaming device is needed, the drive motor 10 can drive the rotating shaft 11 and the stirring paddle 12 to rotate, stirring the oil in the oil tank 1 to achieve the defoaming effect. The guide plate 7 is fixed inside the oil tank 1 by the nut 8. The lower end of the guide plate 7 is attached to the upper surface of the interception net 13, and the upper end of the guide plate 7 is below the exhaust hole 5. The stirred oil flows upward along the guide plate 7, and the bubbles in it float up and are discharged through the exhaust hole 5. A diaphragm is installed in the exhaust hole 5 to prevent oil leakage. The oil tank 1 and the monitoring tank 15 are fixed by the partition 14. The treated oil flows down through the filter hole of the partition 14 and enters the monitoring tank 15 for monitoring. The laser emitter 16 and the photoelectric receiver 18 are symmetrically installed on both sides of the cavity. The temperature sensor 17 is used to collect the oil temperature data to correct the optical monitoring error.

[0033] In addition, L-shaped grooves 9 are added to both sides of the inner wall of the oil tank 1. The intercepting net 13 is fixed by the slider 19 and the intercepting net 13 is moved to slide on the inner wall of the L-shaped groove 9, so that the intercepting net 13 can be easily removed for cleaning. The slider 19 is internally threaded with a limit screw 20. When the slider 19 moves the intercepting net 13 to the round groove at one end of the L-shaped groove 9, the limit screw 20 is manually turned to limit and lock the intercepting net 13.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
