Description

Technical Field

[0001] This utility model relates to the field of turbine oil filtration technology, specifically a device for improving the demulsification of turbine oil. Background Technology

[0002] Turbine oil, also known as turbine lubricant, is mainly used in the lubrication of steam turbines in power plants, hydroelectric generators in hydropower stations, and other applications requiring highly refined lubricating oil. Its primary functions are lubrication, heat dissipation, cooling, and speed regulation. Demulsibility is an important performance indicator of turbine oil, representing its ability to separate oil and water. If the water content in the turbine oil reaches saturation, the presence of surface-active substances that can cause emulsification, along with the agitation generated during system circulation, will lead to emulsification. This not only damages the oil's film-forming and extreme pressure characteristics, severely affecting its lubrication performance and endangering the safe operation of the turbine, but also accelerates oil deterioration and causes corrosion on metal surfaces. To improve the demulsibility of turbine oil, appropriate filtration devices are needed to effectively remove particulate matter and active substances.

[0003] According to a search, Chinese patent document CN221155604U discloses an online device for improving the demulsification of turbine oil. This device uses a rack fixedly mounted on the piston rod of a hydraulic cylinder to drive a driven gear, which in turn drives a rotating shaft. This, in turn, rotates an upper and lower annular frame fixed on the shaft, moving the coarse and fine screen plates adjacent to the filter box into the filter box. This allows for reliable filtration of particulate matter and active substances that affect demulsification, maintaining good filtration and effectively improving the demulsification of the turbine oil. Furthermore, the device continuously filters the turbine oil containing impurities during the adjustment of the positions of the dirty coarse and fine screen plates, without interrupting the filtration process due to the coarse and fine screen plates, thus effectively improving filtration efficiency. The dirty screen plates can be quickly removed from the outer cylinder for cleaning and maintenance via slots on each screen plate, insert rods that can be inserted into the slots, screen plate mounting ports on the annular frame, and screen plate removal ports on the outer cylinder. After maintenance, the screen plates can be returned to their original positions through the corresponding removal ports, greatly extending the service life of the device and preventing interruption of oil filtration due to screen plate cleaning. However, during use, although dirty screen plates can be quickly removed from the outer cylinder for cleaning and maintenance through the removal ports, dirt residue remains on the fixed and through holes of the screen plates during filtration, which can easily lead to reduced filtration efficiency, clogging, or decreased filtration volume. Moreover, cleaning requires removing the dirty screen plates from the outer cylinder, making disassembly and assembly cumbersome and time-consuming, which can easily affect the continuity and efficiency of filtration, resulting in poor ease of use.

[0031] Specifically, four annularly spaced diversion holes are provided on the bottom side of the inner side of the diversion chamber 2, and two sealing doors 11 are provided in total, which are respectively set on the front side of the filter cartridge 1 by hinges. An oil storage chamber is provided at the lower end of the inner side of the filter cartridge 1. The advantages are that the four diversion holes provided on the inner side of the diversion chamber 2 facilitate the diversion of engine oil, thereby improving the filtration effect. Moreover, the sealing doors 11 facilitate the sealing of the filter cartridge 1 and make it convenient to remove the storage cylinder 7 for cleaning later.

[0032] Specifically, the cleaning frame 4 includes an inner sleeve 401, an outer sleeve 402, a connecting plate 403, and a brush plate 404. The inner sleeve 401 is movably installed on the outer side of the middle of the base plate 5, and the outer sleeve 402 is fixedly installed on the inner side of the filter cartridge 1. The connecting plate 403 is fixedly installed between the inner sleeve 401 and the outer sleeve 402, and the brush plate 404 is provided on the bottom side of the connecting plate 403. The advantage is that by starting the motor 8, the two sets of base plates 5 and the screen plate 6 are driven to rotate, which facilitates the cleaning of the screen plate 6 by the brush plate 404 on the bottom side of the cleaning frame 4, avoiding the reduction of oil filtration caused by clogging of the holes.

[0033] Specifically, the top side of the substrate 5 is provided with an inclined groove 501 and a mounting groove 502. Several through holes are provided inside the mounting groove 502. A fixing seat 503 is fixedly mounted on the top side of the substrate 5. An inner sleeve 401 is movably mounted on the outer side of the fixing seat 503 via a bearing. There are two substrates 5 in total, and a connecting frame 504 is fixedly mounted between them. The advantages are that the mounting groove 502 facilitates the installation of the screen plate 6, and the inclined groove 501 helps to discharge clean dirt into the storage cylinder 7, thereby achieving the function of cleaning the screen plate 6. Furthermore, the connecting frame 504 facilitates the synchronous rotation of the two sets of substrates 5.

[0034] Example 2:

[0035] like Figure 1-6 As shown, this is an improvement on the previous embodiment. Specifically, a limiting cylinder 505 is fixedly installed on the bottom side of the substrate 5, and the lower end of the inner side of the limiting cylinder 505 is provided with an internal thread. A storage cylinder 7 is threadedly connected to the inner side of the limiting cylinder 505. The screen plates 6 are bolted to the inner side of the mounting groove 502, and four screen plates 6 are arranged in a group, for a total of two groups.

Moreover, with the action of the through groove 701 and the screen 702, it is conducive to filtering the engine oil and the stored dirt, thereby avoiding the waste of engine oil resources.

[0037] During use, engine oil is delivered to the inside of the distribution chamber 2 through the oil inlet pipe 9. The oil then flows through four distribution holes to the inside of the filter chamber 3 and is filtered by four sets of sieve plates 6, which improves filtration efficiency. Furthermore, even if engine oil enters the inside of the storage cylinder 7 through the inclined groove 501 during filtration, it can still be filtered by the screen 702, preventing leakage. After being filtered by two sets of base plates 5 and sieve plates 6, the oil is discharged through the oil outlet pipe 10, further improving filtration quality. During the filtration process, the motor 8 drives the two sets of substrates 5 and screen plates 6 to rotate, which facilitates the cleaning of screen plates 6 by the brush plate 404 on the bottom side of the cleaning frame 4, avoiding clogging of the holes and reducing the amount of oil filtered. The dirt cleaned is then discharged into the inclined channel 501 by the brush plate 404 and flows into the storage cylinder 7 for collection and filtration. This makes it convenient to remove and clean the storage cylinder 7 later by opening the sealing door 11 and rotating it. The cleaning is convenient and quick, which improves the ease of use and avoids the reduction of oil filtration rate due to filtration interruption.
