[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] like Figures 1-2 As shown: A wind turbine bearing grease cleaning device, comprising:
[0036] The housing 1 is provided with multiple partitions 108, which divide the housing 1 into multiple working areas, and two adjacent working areas are interconnected; wherein, the multiple working areas are, in order, a cleaning area, a filtering area, and a storage area.
[0037] Spray gun 2, the inlet end of which is connected to the storage area via a hose, and the outlet end of the spray gun 2 which introduces the cleaning fluid from the storage area into the cleaning area.
[0038] When cleaning the lubricating grease from the wind turbine bearing, place the bearing above the cleaning area and use spray gun 2 to clean the bearing. The cleaning fluid flows along the inside of the housing 1. Figure 2 The flow is in the direction of the dashed line shown.
[0039] Two baffles 101 are fixedly installed in the cleaning zone, which divide the cleaning zone into a fluctuating part and a stable part. A Z-shaped channel connecting the fluctuating part and the stable part is formed between the two baffles 101.
[0040] During the cleaning process, the cleaning fluid first falls into the undulating section. Under the influence of the spray gun 2, the cleaning fluid in the undulating section is in a undulating state. When the cleaning fluid flows into the stable section through the buffer of the Z-shaped channel, the flow direction is stable and the flow rate is low. At this time, the liquid flow is relatively stable, and the undissolved large particles of lubricating grease in the cleaning fluid are deposited at the bottom of the cleaning zone.
[0041] Both the bottom surfaces of the cleaning zone and the filtration zone are provided with drain outlets 102, and the side walls of the cleaning zone and the filtration zone near the bottom surface are provided with cleaning outlets 103.
[0042] The grease deposited at the bottom of the cleaning zone and the filtration zone can flow out through the drain port 102, and the bottom of the cleaning zone and the filtration zone can be flushed through the cleaning port 103.
[0043] A first through hole is provided on the partition 108 between the cleaning zone and the filtration zone. The first through hole is located near the bottom surface of the housing 1 on the partition 108. The stabilized cleaning solution flows into the filtration zone through the first through hole.
[0044] An annular plate 104 is fixedly installed in the filtration zone, and the outer side wall of the annular plate 104 is fixedly connected to and fits against the inner side wall of the filtration zone.
[0045] A filter element 105 is placed on top of the annular plate 104, and the horizontal projection of the filter element 105 completely covers the horizontal projection of the inner sidewall of the annular plate 104. The cleaning fluid flows from bottom to top through the filter element 105, and the undissolved small particles of lubricating grease in the cleaning fluid are also filtered out under the action of the filter element 105. At this time, the particles in the cleaning fluid above the filter element 105 are filtered clean and will not affect the operation of the spray gun 2, so it can be reused.
[0046] The filter element 105 includes:
[0047] Filter cage 10501, wherein the filter cage 10501 is a rectangular cage made of metal;
[0048] Filter sheet 10502, wherein multiple filter sheets 10502 are provided and multiple filter sheets 10502 are stacked in filter cage 10501;
[0049] When the filtration effect decreases, after removing the filter cage 10501, you can replace some of the filter plates 10502, or you can replace the entire filter cage.
[0050] A second through hole is provided on the partition 108 between the filtration zone and the storage zone. The second through hole is located on the partition 108 away from the bottom surface of the housing 1. The cleaning fluid flows into the storage zone through the second through hole.
[0051] A guide plate 106 is fixed on the end face of the partition 108 in the storage area. A guide channel is formed between the guide plate 106 and the partition 108. The guide channel is connected to the second through hole, which is located inside the guide channel. Under the action of the guide plate, the cleaning fluid flows steadily through the guide channel into the storage area, preventing air bubbles in the cleaning fluid from affecting the use of the spray gun 2 due to the presence of air inside.
[0052] The storage area is connected to a fluid exchange pipe 107 for replacing the cleaning fluid. When the cleaning fluid still cannot meet the cleaning requirements after filtration, the old cleaning fluid is extracted through the fluid exchange pipe 107 and new cleaning fluid is injected through the fluid exchange pipe 107.
[0053] The inlet end of the spray gun 2 is connected to one end of the outlet pipe 201 via a hose, and the other end of the outlet pipe 201 passes through the box 1 and is inserted into the storage area.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
