Description

Technical Field

[0001] This utility model relates to the technical field of impurity adsorption devices, and more specifically, to an adsorption device for metal impurities in an oil system. Background Technology

[0002] In the field of thermal power plant production, the operation of the steam turbine directly affects the overall plant efficiency. During steam turbine operation, the safe and reliable operation of the oil system is crucial. Its main functions include:

[0003] 1. Lubrication: Forms an oil film between high-speed rotating components such as bearings, gearboxes, and couplings in the steam turbine to prevent direct metal-to-metal contact, reduce wear, and extend the service life of bearings and transmission components.

[0004] 2. Cooling: When the steam turbine is running, the bearings and gears will generate high temperatures due to friction. The oil system carries away the heat through circulating oil, keeping the equipment within a safe temperature range.

[0005] 3. Speed ​​regulation and control: The load and speed are adjusted by pulling the regulating valve through the hydraulic motor, and the emergency shutdown system relies on hydraulic pressure to trigger the shutdown protection, etc.

[0006] 4. Cleaning and corrosion prevention: The oil filter removes impurities from the oil system and removes water from the oil. The oil contains antioxidants that protect the inner walls of pipes and equipment.

[0007] However, although most power plants currently use technologically mature steam turbine units, metallic impurities still exist in the oil system:

[0008] First, the long-term operation of steam turbines causes wear on the bearings. Since the bearings are made of iron, some of the iron filings and impurities generated by the wear enter the oil system.

[0009] Secondly, vacuum oil filters have poor filtration efficiency and cannot effectively filter out all metal impurities.

[0010] Third, oil oxidation or the presence of metallic impurities in the oil itself can reduce the effectiveness of the lubricating oil. If the amount of metallic impurities increases, it may lead to unit shutdown or equipment damage.

[0011] To ensure the normal operation of steam turbine units, current technologies mostly rely on oil replacement to remove metallic impurities from the oil system and require replacing the filter elements of dual-cylinder oil filters to improve filtration efficiency. This leads to the waste of qualified oil and incurs additional expenses for environmental treatment. Therefore, finding a way to remove metallic impurities from the oil system without replacement has become a problem to be solved. Utility Model Content

[0012] The purpose of this invention is to provide an oil system metal impurity adsorption device that can adsorb metal impurities in oil without replacing the oil, thereby reducing the concentration of metal impurities in the oil system, extending the service life of the equipment, promoting the safe operation of the unit, and reducing the replacement cost of the oil system and the frequency of replacement of the dual-cylinder oil filter element.

[0015] The clamping component is fixed to the bottom plate of the inner wall of the oil tank, and the magnetic component is clamped to the clamping component so that the magnetic component and the clamping component form a detachable connection.

[0016] The extraction mechanism has a connecting part for extending into the oil tank from the operating port and connecting with the magnetic component. The extraction mechanism is used to separate the magnetic component from the clamping component under the action of external force.

[0017] Furthermore, in some embodiments of this utility model, the extraction mechanism includes an extraction pull rod, with a connecting part located at the bottom of the extraction pull rod and being an arc shape with the opening facing upward; one end of the connecting part is connected to the extraction pull rod, and the other end of the connecting part is a free end;

[0018] The magnetic component has a pull ring that mates with the connecting part.

[0019] Furthermore, in some embodiments of this utility model, the removal mechanism also includes a handle, which is located at the top of the removal lever.

[0024] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0025] During oil system operation, metallic impurities in the oil settle to the bottom of the oil tank under their own gravity. Simultaneously, magnetic components attract these impurities, preventing them from flowing with the oil. This reduces the concentration of metal filings in the flowing lubricating oil, extending equipment lifespan and promoting safe unit operation. After a period of use, the magnetic components can be removed using a removal mechanism to clean the adsorbed metallic impurities. Therefore, metallic impurities in the oil can be adsorbed without replacing the oil, reducing the concentration of metallic impurities in the oil system, extending equipment lifespan, and promoting safe unit operation. This also reduces the frequency of lubricating oil replacement and dual-cylinder oil filter element replacement, saving production costs. Attached Figure Description

[0038] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0039] Example

[0040] Please refer to Figures 1-3 This embodiment provides an oil system metal impurity adsorption device, including an oil tank 10 and a magnetic component 20. The top of the oil tank 10 has an operation port 11, and the magnetic component 20 is located inside the oil tank 10. In this embodiment, the magnetic component 20 is a cylindrical magnetic rod, which is placed horizontally during installation. It also includes a clamping component 30 and a removal mechanism 40. The clamping component 30 is fixed to the bottom plate of the inner wall of the oil tank 10, and the magnetic component 20 is clamped to the clamping component 30 so that the magnetic component 20 and the clamping component 30 form a detachable connection. The removal mechanism 40 has a connecting part 41, which is used to extend into the oil tank 10 from the operation port 11 and connect with the magnetic component 20. The removal mechanism 40 is used to separate the magnetic component 20 from the clamping component 30 under the action of external force. The extraction mechanism 40 includes an extraction lever 42, a connecting part 41 located at the bottom of the extraction lever 42 and being an arc shape with the opening facing upward; one end of the connecting part 41 is connected to the extraction lever 42, and the other end of the connecting part 41 is a free end; the magnetic component 20 has a pull ring 21 that cooperates with the connecting part 41.

[0041] In the specific implementation process, the magnetic component 20 is installed on the clamping component 30 inside the oil tank 10. The magnetic component 20 is clamped and fixed by the clamping component 30. During the use of the oil system, the metal impurities in the oil settle to the bottom of the oil tank 10 under their own gravity. At the same time, the metal impurities can be adsorbed onto the surface of the magnetic component 20 through adsorption. This can prevent the metal impurities from flowing with the oil, thereby reducing the concentration of metal filings in the flowing lubricating oil, improving the service life of the equipment, and promoting the safe operation of the unit.

[0042] After a period of use, the oil in the oil tank 10 can be extracted, and the magnetic component 20 can be removed using the extraction mechanism 40 to clean the metal impurities adsorbed on the surface of the magnetic component 20. In specific operation, the user holds the extraction mechanism 40 so that the connecting part 41 extends into the oil tank 10 from the operation port 11, hooks the pull ring 21 of the magnetic component 20 through the connecting part 41, and then pulls the extraction mechanism 40 upwards. The magnetic component 20 is pulled out from the clamping part 30 through the connecting part 41, so that the magnetic component 20 can be separated from the clamping part 30. The magnetic component 20 can then be pulled out from the operation port 11 for cleaning. After cleaning, the magnetic component 20 and the oil can be reinstalled.

[0043] Therefore, the oil system metal impurity adsorption device provided in this application can adsorb metal impurities in oil without replacing the oil, reducing the concentration of metal impurities in the oil system. This prevents excessive metal impurities in the oil system from causing unit shutdowns, equipment damage, etc., extending equipment lifespan, and promoting safe unit operation. It can reduce the frequency of lubricating oil replacement and the frequency of dual-cylinder oil filter element replacement, saving production costs. Currently, lubricating oil is replaced irregularly based on quality inspection results, and the dual-cylinder oil filter element is replaced approximately once a year. With the implementation of this patent, it is expected that the filter element can be replaced for 2-3 years, extending its service life. Turbine oil pressure fluctuations can affect equipment safety, such as bearing overheating, which can easily lead to equipment failure and shutdown. This application can avoid lubricating oil pressure fluctuations during lubricating oil replacement.

[0044] like Figure 1 and Figure 3 As shown, in some embodiments, the removal mechanism 40 further includes a handle 43, which is located at the top of the removal lever 42. By providing the handle 43, this invention facilitates operation of the removal mechanism 40 by the user holding the handle 43 when removing the magnetic component 20, making it more convenient to use.

[0045] like Figures 1-2 As shown, in some embodiments, the clamping member 30 has an upward-facing clamping groove 31, which is C-shaped, into which the magnetic member 20 is embedded. This facilitates the insertion and clamping of the magnetic member 20 into the clamping groove 31, and also makes it easy to pull the magnetic member 20 out of the clamping member 30, thus simplifying the operation. In this embodiment, the clamping member 30 can be made of metal, which, after forming the clamping groove 31, is elastic, facilitating the installation and removal of the magnetic member 20.

[0046] like Figures 4-5 As shown, in some embodiments, the adsorption device further includes a mounting mechanism 50, which includes a mounting rod 51 and a clamping seat 52 disposed at the bottom of the mounting rod 51. The magnetic element 20 is detachably connected to the clamping seat 52. The clamping seat 52 has a downward-facing clamping cavity 521, which is C-shaped, and the magnetic element 20 can be embedded in the clamping cavity 521.

[0047] This utility model, by setting up an installation mechanism 50, allows the magnetic component 20 to be reinstalled into the clamping component 30 after cleaning. Specifically, the cleaned magnetic component 20 is inserted into the clamping cavity 521 so that it is clamped onto the clamping seat 52. The user holds the installation rod 51 and moves the clamping seat 52 into the oil tank 10. The magnetic component 20 is aligned with the clamping groove 31 of the clamping component 30. Then, the installation mechanism 50 is moved downwards so that the magnetic component 20 is inserted into the clamping groove 31 for clamping and fixing. At this point, the installation mechanism 50 is pulled out to complete the reinstallation of the magnetic component 20. The operation is convenient.

[0048] The clamping base 52 in this embodiment can be made of metal. After forming the clamping cavity 521, it is elastic, which facilitates the installation and removal of the magnetic component 20. It should be noted that the clamping force of the clamping base 52 on the magnetic component 20 in this embodiment is less than the clamping force of the clamping member 30 on the magnetic component 20. In this way, when the magnetic component 20 is installed and the installation mechanism 50 is pulled upward, the magnetic component 20 can be prevented from being pulled out of the clamping member 30.

[0049] like Figures 1-2 As shown, in some embodiments, multiple sets of clamping members 30 are spaced apart inside the oil tank 10, each set including two clamping members 30 spaced apart. By providing multiple sets of clamping members 30, each set of clamping members 30 can clamp one magnetic member 20, thereby improving the adsorption effect on metal impurities.

[0050] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application. The terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance; "multiple" refers to at least two. In this application embodiment, the limitations on relative positional relationships such as parallel, perpendicular, and aligned are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallel, perpendicular, and aligned are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees.

In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Any combination of features in different embodiments is also within the protection scope of this application.
