Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and more specifically, to a cleaning device for turbine blades. Background Art

[0002] Turbine blades are an important component of the turbine section of a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure airflow into the burner to maintain the operation of the engine. In order to ensure stable and long-term operation under extreme conditions of high temperature and high pressure, turbine blades are often forged from high-temperature alloys and cooled in different ways, such as internal airflow cooling, boundary layer cooling, or thermal barrier coatings to protect the blades, to ensure reliability during operation.

[0003] When cleaning turbine blades, a cleaning device is often used. Although the existing cleaning device can achieve basic cleaning functions during actual use, a filter screen is generally installed inside the existing cleaning device to filter the sewage after cleaning. The filter screen will absorb a large amount of impurities when working for a long time, which reduces the efficiency of sewage filtration and increases the cleaning time of the turbine blades. Therefore, it needs to be improved. Utility Model Content

[0036] Such a design makes it easy for an operator to open the cover plate 12 by pulling the second handle 13 .

[0037] The right side of the sewage tank 1 is fixedly connected with a liquid collecting box 14 , and the top of the liquid collecting box 14 is fixedly connected with a liquid guiding pipe 15 .

When the latch 9 moves to the top of the filter screen plate 3, the fixing effect of the filter screen plate 3 will be released. At this time, pulling the first handle 4 can achieve the purpose of quickly disassembling and replacing the filter screen plate 3.
