Description

Technical Field

[0001] The utility model relates to the field of gas filtering equipment, in particular to a gas filtering device for a gas bearing of a fan. Background Art

[0002] Gas bearings use gas as a medium to lubricate bearings, forming an air film between the shaft and the bearing to avoid direct contact between the moving shaft surface and the stationary bearing surface, reducing friction between the two, and increasing the service life of the bearing. Therefore, the purity of the gas in a high-speed fan is crucial to extending the service life of the bearing. After searching the application number CN201821406569.8, a gas filtration device for a fan gas bearing was disclosed, which records that it includes a housing, a coarse filter component and a fine filter component. An air inlet is formed on one side of the housing, and an air outlet is opened on the other side of the housing. The coarse filter component covers the air inlet, and the fine filter component is arranged inside the housing and divides the interior of the housing into two cavities. The air inlet and the air outlet are respectively located on both sides of the fine filter component; the fine filter component protrudes in the direction away from the coarse filter component. The utility model can realize two-stage filtration of gas. The fine impurity dust in the gas that cannot be filtered by the coarse filter component can be filtered through the fine filter component, thereby effectively improving the filtering effect. By setting the fine filter component to protrude in the direction away from the coarse filter component, the filtering area of ​​the fine filter component can be effectively increased to ensure its filtering efficiency, thereby achieving the effect of improving the filtering effect and reducing the fine impurity dust in the air through multi-stage filtration while ensuring the inlet flow of the fan. However, the device still has the following defects in actual use: the device is not convenient for installing and replacing the filtering structure when in use, and some parts can be recycled during the filtering process. Therefore, it is necessary to design a gas filtering device with strong practicality for the gas bearing of the fan. Utility Model Content
