Description

Technical Field

[0001] The utility model belongs to the technical field of blade polishing, in particular to a compressor stator blade polishing device. Background Art

[0002] The stationary blades, also called stator blades for short, are stationary blades fixed on the partition or guide vane holding ring. They can guide the steam flow in the compressor. The existing stationary blades need to be polished during the production process to make their surface smooth and flat in order to ensure the later use effect.

[0003] Publication No.: CN219255117U, discloses: a compressor stator blade polishing device. When in use, when dust accumulates on the upper surface of the base plate, pull the handle to drive the scraper to move out of the protection box. At this time, the scraper will drive the brush installed on its bottom surface to move with it. The brush contacts the upper surface of the base plate to scrape the dust on the surface of the base plate, and clean the dust into the collection tank for collection. When the scraper is moved out of the protection box, the elastic member is stretched so that the elastic member generates a pulling force on the scraper. After releasing the handle, the elastic member will pull the scraper to perform a reset operation.

[0004] The above solution has the following deficiencies in actual use:

[0005] The dust accumulated on the bottom plate can only be cleaned after polishing is completed. When cleaning the dust, the staff needs to manually pull the handle to drive the scraper and the brush to move, and scrape the dust accumulated on the bottom plate to the collection tank, which increases the workload of the staff. In the cleaning process, dust is easily raised and inhaled by the human body, which seriously endangers human health and makes the dust cleaning effect generated by polishing poor.

[0006] In view of the above problems, we propose a compressor stator blade polishing device. Utility Model Content
