Description

Technical Field

[0001] This utility model relates to an anti-bubble device for an online oil monitoring tank, used to eliminate bubbles generated inside the oil tank, thereby eliminating the impact of bubbles on detection accuracy. Background Technology

[0002] Stainless steel mills require oil quality testing during operation, with real-time online monitoring of key indicators such as moisture content, water activity, viscosity, temperature, and particle size. Existing online oil contamination detection technology uses the optical obscuration method to measure contaminant particles in the oil. This method accurately and quickly detects the quantity and size distribution of contaminant particles, outputting the contamination level according to relevant standards. The primary monitoring focus is on the equipment's return oil path. However, equipment operation and pressure changes generate numerous air bubbles in the oil, affecting the accuracy of the detection. Therefore, timely removal of these air bubbles during contamination detection is crucial.

[0003] An investigation revealed that the existing Chinese patent CN201420750459.9, entitled "A Device for Monitoring and Eliminating Air Bubbles in Oil Contamination Detection," includes an oil pipe made of transparent material, several magnifying glasses with varying magnifications attached to the outer surface of the oil pipe, and a pressure monitoring device installed inside the oil pipe, wherein the pressure monitoring device is a pressure sensor; a flow control valve is connected in parallel with the pressure sensor and the contamination sensor, respectively, and the pressure sensor and the contamination sensor are connected in series. This device can observe the presence of air bubbles in the oil through the air bubble monitoring device, and when air bubbles are present, it reduces the pump flow rate to avoid air bubble generation. However, this device can only reduce air bubble generation and cannot completely eliminate air bubbles, therefore its effectiveness is not ideal. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an air-bubble elimination device for an online oil monitoring box with a reasonable structural design and good performance, in view of the above-mentioned technical status.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an anti-bubble device for an online oil monitoring box, characterized in that: it includes a box body, an oil inlet and an oil outlet are provided on the box body, an anti-bubble seat is provided inside the box body, an anti-bubble chamber is provided inside the anti-bubble seat, the anti-bubble chamber is connected to the oil inlet and the oil outlet through an oil inlet pipe and an oil outlet pipe respectively, an oil inlet pump is installed on the oil inlet pipe, and the oil outlet pipe is divided into two paths, wherein the first path discharges air bubbles and the second path discharges oil, and a one-way valve and a flow regulating valve are installed on both the first path and the second path.

[0006] As an improvement, the upper end of the de-bubbling chamber is conical, and a vertical partition wall is provided in the middle of the de-bubbling chamber to divide the de-bubbling chamber into two chambers, left and right. There is a certain gap between the upper end of the partition wall and the conical top of the de-bubbling chamber. The oil inlet is located on the left side of the de-bubbling chamber, and the oil port is located on the left side of the housing.

[0007] Furthermore, the first pipeline is installed at the upper middle position of the de-bubbling seat. An exhaust port oil pipe is opened on the de-bubbling seat and above the top of the isolation wall and connected to the first pipeline. The second pipeline is installed on the upper right side of the de-bubbling seat. The lower end of the second pipeline extends to the bottom of the right cavity of the de-bubbling chamber. The bubbles separated by the oil in the de-bubbling chamber under pressure gather at the top of the de-bubbling chamber and are discharged through the first pipeline. The oil without bubbles in the de-bubbling chamber is discharged through the second pipeline.

[0008] Furthermore, the oil inlet is connected to the oil intake interface of the oil circuit under test, and the oil outlet is connected to the oil return interface of the oil circuit under test.

[0009] Finally, a contamination sensor is installed in the second pipeline between the check valve and the flow regulating valve.

[0010] Compared with existing technologies, the advantages of this invention are as follows: An oil inlet pump and a de-bubbling seat are installed inside the housing. The top of the de-bubbling chamber within the de-bubbling seat is designed in a conical shape, and an isolation wall is installed inside the de-bubbling chamber. This allows the bubbles separated by the oil entering the de-bubbling chamber to accumulate at the top of the chamber under pressure and be discharged through the first pipeline. Oil without bubbles in the de-bubbling chamber is discharged through the second pipeline. Two oil outlet pipelines are designed, each equipped with a flow regulating valve and a check valve, allowing for flow rate adjustment as needed. The first pipeline only discharges bubbles, while the second pipeline discharges oil. The check valve prevents backflow and cross-contamination of oil between the two pipelines due to pressure differences or flow rate variations. This invention has a simple and reasonable structure and ingenious design. It can pressure-eliminate and separate tiny bubbles generated during oil flow during equipment operation. After bubble elimination, the oil enters and exits the contamination sensor's detection oil circuit, ensuring that the oil detection by the contamination sensor is not affected by bubbles, thus ensuring the accuracy and stability of the detection equipment.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] Example 1

[0016] like Figure 1 As shown, an anti-bubble device for an online oil monitoring box includes a box body 1, with an oil inlet 11 and an oil outlet 12. An anti-bubble seat 2 and an oil pump 3 are provided inside the box body 1. An anti-bubble chamber 20 is provided inside the anti-bubble seat 2. The anti-bubble chamber 20 is connected to the oil inlet 11 and the oil outlet 12 through an oil inlet pipe 10 and an oil outlet pipe, respectively. The oil pump 3 is installed on the oil inlet pipe 10. The oil outlet pipe is divided into two paths, namely a first pipe 40 and a second pipe 30. The first pipe 40 discharges air bubbles, and the second pipe 30 discharges oil. One-way valves 4 and 6 and flow regulating valves 5 and 7 are installed on both the first pipe 40 and the second pipe 30.

[0017] The specific structure is as follows: the upper end of the de-bubbling chamber 20 is designed in a conical shape. A vertical partition wall 21 is installed in the middle of the de-bubbling chamber 20, dividing the de-bubbling chamber 20 into two chambers, left and right. There is a certain gap between the upper end of the partition wall 21 and the conical top of the de-bubbling chamber 20. The oil inlet is located on the left side of the de-bubbling chamber 20, and the oil inlet 11 is located on the left side of the housing 1. The oil inlet 11 is connected to the oil sampling interface of the oil circuit under test, and the oil outlet 12 is connected to the oil return interface of the oil circuit under test.

[0018] The first pipe 40 is installed at the middle of the upper end of the de-bubbling seat 2. An exhaust pipe 22 is provided on the de-bubbling seat 2 above the top of the isolation wall 21 and is connected to the first pipe 40. The second pipe 30 is installed on the upper right side of the de-bubbling seat 2 and the lower end of the second pipe 30 extends to the bottom of the right cavity of the de-bubbling chamber 20.

[0019] In this way, the bubbles separated from the oil in the de-bubbling chamber 20 under pressure gather at the top of the de-bubbling chamber 20 and are discharged through the first pipe 40, while the oil without bubbles in the de-bubbling chamber 20 is discharged through the second pipe 30.

[0020] The working principle is as follows:

[0021] The oil inlet 11 is connected to the oil outlet of the oil being tested. The oil first enters the oil inlet of the de-bubbling chamber 20 through the oil inlet pipe 10. When the oil pump 3 pumps the oil into the de-bubbling seat 2, it creates pressure in the chamber. When the oil enters the left chamber of the de-bubbling chamber 20, the pressure causes the air bubbles in the oil to flow upwards. Therefore, the oil in the chamber will separate the air bubbles under the pressure. The air bubbles in the oil flow upwards and gather in the cone-shaped part of the chamber. The oil without air bubbles accumulates in the right chamber. Then, there is a partition wall 21 between the two chambers. The top of the partition wall 21 has an exhaust hole. The oil pipe 22 is connected to the first pipeline 40. Therefore, the oil with air bubbles flowing above the cone part of the chamber enters the first pipeline 40 under the pressure and flows out of the chamber into the oil outlet 12. As air bubbles are expelled from the first pipe 40, the oil at the bottom of the right chamber of the de-bubbling chamber 20 is separated and becomes oil-free. At this time, a second pipe 30 extends to the bottom of the right chamber and connects, causing the oil to flow out under pressure. This separates the oil with and without air bubbles through different pipes. Both the first pipe 40 and the second pipe 30 are equipped with flow regulating valves 5 and 7 and check valves 4 and 6. The flow rates of the two pipes 40 are adjusted according to different needs. Since the first pipe 40 only functions to expel air bubbles, its flow rate is set to be relatively high. The oil flow rate of the second pipe 30 is adjusted according to usage requirements. Check valves 4 and 6 prevent backflow and cross-contamination of oil between the two pipes 40 and 30 due to pressure differences or flow rate variations. Finally, the flow rates from the two pipes 40 and 30 converge at the oil outlet 12 and flow into the return oil port.

[0022] Example 2

[0023] like Figures 2-3 As shown, based on Example 1, the first pipeline 40 removes air bubbles. The one-way valve prevents backflow of oil containing air bubbles, ensuring accurate detection. A contamination sensor 8 is installed in the second pipeline between the one-way valve and the flow regulating valve. The oil with air bubbles removed by the second pipeline 30 is then passed through the contamination sensor 8 to detect the cleanliness of the oil. Direct air bubbles in the oil flow affect the use of the detection equipment. This de-bubbling device ensures the oil is bubble-free, guaranteeing the stability of the detection equipment and preventing inaccurate data due to excessive air bubbles.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
