Description

Technical Field

[0001] The utility model relates to the field of oil-gas separation, and in particular to an oil-gas separation structure of a scroll compressor. Background Art

[0002] Scroll compressors are usually used to compress gas to a higher pressure level. In order to ensure the efficient operation of the compressor and reduce the impact on downstream equipment, an effective oil-gas separation structure is required to prevent the oil-gas mixture from entering the exhaust end of the compressor. The scroll compressor oil-gas separation structure can effectively separate gas and liquid and prevent oil from entering the exhaust end of the compressor, thereby improving the performance and reliability of the compressor.

[0003] However, most of the current scroll compressor oil-gas separation structures have the following problems:

[0004] 1. The existing scroll compressor oil-gas separation structure, when performing separation, mostly filters the residual oil in the gas through a filter screen, etc., but after a long period of filtration, the oil filtered on the filter screen condenses and falls, and some oil is likely to remain on the filter screen. If the oil stays on the filter screen for a long time, it is easy to cause the oil on the filter screen to solidify. The solidified oil blocks the filter screen and easily affects the filtration efficiency, making it inconvenient to easily handle the filter screen.

[0005] 2. The existing scroll compressor oil-gas separation structure uses an oil-gas separation tube for processing. Most of the oil-gas separation tubes are bolted or welded. After long-term use, oil is likely to remain on the surface and inner wall of the oil-gas separation tube. If it is not disassembled and cleaned in time, it is easy to affect the stability of the oil-gas separation tube, and it is inconvenient to disassemble and install the oil-gas separation tube conveniently.

[0006] Therefore, we made improvements to this and proposed an oil-gas separation structure for a scroll compressor. Utility Model Content

[0034] like Figure 1-7As shown, the present embodiment proposes an oil-gas separation structure of a scroll compressor, comprising a housing 1, a bearing 2 is installed in the housing 1, a support plate 3 is installed in the housing 1, a moving plate 4 is installed on the support plate 3, a static plate 5 is installed in the housing 1, a first exhaust port 6 is opened on the static plate 5, a first oil return port 7 is opened on the static plate 5, a top cover 8 is installed on the housing 1, a second exhaust port 9 is opened on the top cover 8, a second oil return port 10 is opened on the top cover 8, an oil-gas separation pipe 11 is installed in the housing 1, and an oil-gas separation pipe 12 is installed in the housing 1. A filter screen 12 is fixedly connected inside the separation tube 11, a connecting shaft 13 is fixedly connected to the filter screen 12, a fan blade 14 is fixedly connected to the connecting shaft 13, a scraper 15 is fixedly connected to the connecting shaft 13, a bump 16 is fixedly connected to the oil-gas separation tube 11, a slide groove 17 is provided on the top cover 8, a slider 18 is limitedly slidably connected inside the slide groove 17, the slider 18 is fixedly connected to the oil-gas separation tube 11, a spring 19 is fixedly connected inside the slider 18, and a connecting plate 20 is fixedly connected to the spring 19.

[0035] Embodiment 2:

[0036] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0037] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, the connecting shaft 13 is fixedly connected to the center of the filter 12, and the fan blades 14 are distributed at equal angles on the connecting shaft 13, which can ensure that the fan blades 14 distributed at equal angles can be driven by the wind to rotate the connecting shaft 13.

[0038] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the scraper 15 is fitted with the side end face of the filter screen 12, and the protrusions 16 are distributed at equal angles on the oil-gas separation tube 11, which can ensure that the scraper 15 can scrape the filter surface of the filter screen 12 when rotating.

[0039] like Figure 7 As shown, as a preferred embodiment, based on the above method, further, the cross-section of the slider 18 is "T"-shaped, and the side end face of the connecting plate 20 is in contact with the inner side face of the slider 18, which can ensure that the "T"-shaped slider 18 can slide in the slide groove 17.

[0040] like Figure 7 As shown, as a preferred embodiment, on the basis of the above method, further, a pull rod 21 is fixedly connected to the connecting plate 20, and a clamping block 22 is fixedly connected to the pull rod 21. The pull rod 21 is fixedly connected to the central part of one side of the connecting plate 20, and the clamping blocks 22 are symmetrically distributed on the pull rod 21, which can ensure that the clamping of the clamping blocks 22 on both sides can limit the pull rod 21.

[0041] Specifically, when the scroll compressor oil-gas separation structure is used: Figure 1-7 The crankshaft is fixed on the bearing 2 of the support plate 3 in the housing 1. The rotation of the crankshaft drives the plane movement of the moving scroll. A high-temperature and high-pressure gaseous refrigerant is formed on the back of the stator plate 5. The gas can be discharged into the top cover 8 through the first exhaust port 6 opened on the stator plate 5 and the second exhaust port 9 on the top cover 8. When the discharged gas with oil passes through the oil-gas separation pipe 11, the protrusion 16 on the oil-gas separation pipe 11 can absorb some oil. When the gas is discharged through the oil-gas separation pipe 11, the oil can be filtered and separated by the filter screen 12 on the oil-gas separation pipe 11. At the same time, the gas can pass through the fan The blades 14 drive the connecting shaft 13 to rotate, and the connecting shaft 13 can drive the scraper 15 to rotate at the same time when rotating. The scraper 15 is attached to the filter screen 12. When rotating, the scraper 15 can scrape and collect the oil filtered on the filter screen 12 to avoid oil residue clogging the filter screen 12, thereby improving the filtering efficiency. The separated oil can flow back through the first oil return port 7 on the static plate 5, and the filtered oil can flow back through the second oil return port 10 on the top cover 8 and the first oil return port 7 on the static plate 5, so as to lubricate the bearing 2 and reduce the friction of the moving plate 4.

[0042] When the oil-gas separation tube 11 needs to be disassembled, the pull rod 21 can be pulled to drive the connecting plate 20 to move, and the connecting plate 20 can squeeze the spring 19. At the same time, the pull rod 21 can drive the block 22 to disengage from the top cover 8 when moving. After disengagement, the slider 18 is not hindered and the slider 18 can be pushed to disengage from the slide groove 17. The slider 18 can take the oil-gas separation tube 11 out of the equipment for cleaning and maintenance. When the oil-gas separation tube 11 needs to be installed, the oil-gas separation tube 11 is inserted into the equipment, and the pull rod 21 is released. The connecting plate 20 is driven to reset under the push of the spring 19. When the connecting plate 20 drives the pull rod 21 to reset, the block 22 can be engaged in the top cover 8 to install and fix the equipment to avoid falling off and improve maintenance stability.

[0043] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods.
