Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a gas turbine air intake mechanism. Background Technology

[0002] The air intake system regulates the airflow and pressure entering the gas turbine through a series of pipes and valves to meet the turbine's needs under different operating conditions. The gas turbine air intake system must ensure a stable air supply to the gas turbine under various environmental conditions, while also filtering out dust, particles, and other impurities from the air to ensure clean air entering the turbine.

[0003] The gas turbine inlet filter chamber disclosed in the existing patent publication number CN207195038U includes a wind cap and a lint-proof frame. After the gas turbine has been running for a long time, the screen holes will be clogged with a lot of willow catkins and other impurities, which is not conducive to the gas turbine's air intake. Therefore, the screen needs to be cleaned regularly. Preferably, the gas turbine inlet filter chamber includes a back-blowing flushing device for blowing and washing the screen inside the lint-proof device.

[0004] When the above-mentioned device is in operation, willow catkins and impurities will clog the screen, reducing the working efficiency of the gas turbine. When cleaning willow catkins and impurities, some willow catkins will still stick to the screen when using reverse flushing, resulting in poor cleaning effect. In order to address the above problems, a gas turbine air intake mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a gas turbine intake mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gas turbine intake mechanism includes a filter chamber and a gas turbine itself. A filter cartridge is fixedly connected inside the filter chamber. At least three sets of filter screens are provided inside the filter cartridge. A rotating rod is rotatably connected to the three sets of filter screens. At least three sets of scrapers are fixedly connected to the rotating rod. One side of the scraper is slidably engaged with one side of the filter screen. The scraper is slidably engaged with the inner wall of the filter cartridge. A drive assembly for driving the rotating rod to rotate and slide on the filter screen is provided inside the filter chamber.

[0008] The filter chamber is rotatably connected to a fixing ring on the surface of the end near the gas turbine. Two sets of sliders are fixedly connected to the fixing ring.

A fixed frame is fixedly connected to the inner wall of the filter chamber near the air inlet, and an electro-hydraulic rod is installed on the fixed frame. The power transmission piston rod of the electro-hydraulic rod is connected to the end of the fixed rod away from the rotating rod.

[0010] In one alternative embodiment: the fixing component includes a mounting groove and a mounting block. The mounting groove is formed at the bottom of a set of sliding groove inner walls. The mounting block is snapped into the mounting groove. The bottom of the slider has a moving groove for sliding with the mounting block. A moving rod is fixedly connected to one side of the mounting block. A spring is sleeved on the moving rod. One end of the spring is connected to the mounting block, and the end of the spring away from the mounting block is connected to one side of the inner wall of the moving groove.

[0014] In one alternative: a rotating ring is mounted on the surface of the fixed ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention incorporates a drive assembly, a rotating rod, a scraper, a filter screen, and a filter cartridge. The drive assembly drives the rotating rod to rotate, which in turn rotates the scraper to clean the willow catkins and impurities clogging the filter screen. Simultaneously, the drive assembly drives the rotating rod to slide on the filter screen, causing the scraper to rotate and move, thus cleaning the willow catkins and impurities on the inner wall of the filter cartridge. This reduces filter screen clogging, lowers the operating efficiency of the gas turbine, and improves cleaning efficiency.

A set of rotating rods 13 are rotatably connected to the three sets of filter screens 15. At least three sets of scrapers 14 are fixedly connected to the rotating rods 13. One side of the scraper 14 is slidably engaged with one side of the filter screen 15. The scraper 14 is slidably engaged with the inner wall of the filter cartridge 12. A drive assembly for driving the rotating rods 13 to rotate and slide on the filter screens 15 is provided inside the filter chamber 11.

[0026] The filter chamber 11 is rotatably connected to a fixing ring 26 on the surface of the end near the gas turbine 24. Two sets of sliders 27 are fixedly connected to the fixing ring 26. A groove 23 is provided on one side of the gas turbine 24 for the sliders 27 to be engaged and rotated. A fixing component for fixing the sliders 27 is provided in the groove 23.

[0027] The drive assembly includes a fixed rod 18 and a telescopic rod. The fixed rod 18 is rotatably connected to one end of the rotating rod 13, and the telescopic rod is fixedly connected to the end of the rotating rod 13 away from the fixed rod 18. A motor for driving the telescopic rod to rotate is installed on the support frame on the inner wall of the filter chamber 11. A fixed frame 16 is fixedly connected to the inner wall of the filter chamber 11 near the air inlet. An electro-hydraulic rod 21 is installed on the fixed frame 16. The power transmission piston rod of the electro-hydraulic rod 21 is connected to the end of the fixed rod 18 away from the rotating rod 13. When the motor starts working, it drives the telescopic rod to rotate. The telescopic rod drives the rotating rod 13 to rotate. The electro-hydraulic rod 21 starts working, driving the fixed rod 18 to extend. The fixed rod 18 drives the positioning block 17 to move in the positioning groove 19, pushing the rotating rod 13 to move. The rotating rod 13 drives the scraper 14 to rotate, cleaning the inner wall of the filter cylinder 12. This can clean willow catkins and impurities, reduce clogging of the filter screen 15, reduce the working efficiency of the gas turbine 24, and improve cleaning efficiency.

[0028] The fixing assembly includes a mounting groove 25 and a mounting block 29. The mounting groove 25 is formed at the bottom of the inner wall of a set of sliding grooves 23. The mounting block 29 is engaged in the mounting groove 25. The bottom of the slider 27 is provided with a moving groove 28 for sliding with the mounting block 29. A moving rod 30 is fixedly connected to one side of the mounting block 29. A spring 31 is sleeved on the moving rod 30. One end of the spring 31 is connected to the mounting block 29, and the end of the spring 31 away from the mounting block 29 is connected to one side of the inner wall of the moving groove 28. The slider 27 is engaged in the sliding groove 23. Rotating the rotating ring 22 drives the fixing ring 26 to rotate. The fixing ring 26 drives the two sets of sliders 27 to slide in the sliding groove 23, so that one set of mounting blocks 29 is squeezed by one side of the inner wall of the mounting groove 25. The spring 31 is squeezed in the moving groove 28, which drives the moving rod 30 to move. Using the elastic force of the spring 31, the mounting block 29 is engaged in the mounting groove 25, which can install the filter chamber 11 and facilitate the removal and maintenance of the filter chamber 11.

[0029] The fixing rod 18 is slidably connected inside the limiting cylinder 20. The limiting cylinder 20 is fixedly connected to one side of the fixing frame 16. Two sets of positioning blocks 17 are fixedly connected to the surface of the fixing rod 18. The limiting cylinder 20 is provided with a positioning groove 19 for sliding with the positioning blocks 17. The fixing rod 18 drives the positioning blocks 17 to move within the positioning groove 19, which can limit the movement of the fixing rod 18.

[0030] Both the filter chamber 11 and the gas turbine 24 are equipped with support columns at their bottoms. The bottom of the support column at the bottom of the filter chamber 11 is fixedly connected with casters. By setting the casters, it is convenient for staff to move the filter chamber 11.

[0031] The bottom of the filter chamber 11 is hinged to a base plate, and a cover plate is provided on the top of the base plate. The cover plate is installed at the bottom of the filter cylinder 12. By setting the base plate and the cover plate, the willow catkins and impurities in the filter cylinder 12 can be cleaned out, reducing the phenomenon of accumulation in the filter cylinder 12.

[0032] A rotating ring 22 is installed on the surface of the fixed ring 26. By setting the rotating ring 22, it is convenient for the staff to rotate the fixed ring 26.

[0033] The working principle of this utility model is as follows: When installing the filter chamber 11, the filter chamber 11 is pushed to move so that the air outlet of the filter chamber 11 is aligned with the air inlet of the gas turbine 24, so that the slider 27 is inserted into the slide groove 23. The rotating ring 22 is rotated to drive the fixed ring 26 to rotate. The fixed ring 26 drives the two sets of sliders 27 to slide in the slide groove 23, so that a set of mounting blocks 29 are squeezed by the inner wall of the mounting groove 25. The spring 31 is squeezed in the moving groove 28 to drive the moving rod 30 to move. The elastic force of the spring 31 is used to insert the mounting block 29 into the mounting groove 25. Air enters the gas turbine 24 through the air inlet of the filter chamber 11. The gas turbine 24 compresses the air, and the willow catkins and impurities in the air are blocked and filtered by the filter screen 15.

[0034] When cleaning is required, the motor starts working, driving the telescopic rod to rotate. The telescopic rod drives the rotating rod 13 to rotate, which in turn drives the scraper 14 to rotate, scraping away the willow catkins and impurities on the filter screen 15. The electric hydraulic rod 21 starts working, driving the fixed rod 18 to extend. The fixed rod 18 drives the positioning block 17 to move within the positioning groove 19, pushing the rotating rod 13 to move. The rotating rod 13 drives the scraper 14 to rotate, cleaning the inner wall of the filter cylinder 12. The cleaned impurities fall to the bottom of the inner wall of the filter cylinder 12. The staff can then open the bottom plate of the filter chamber 11 and use external tools to open the bottom cover of the filter cylinder 12 to clean the impurities. This process can remove willow catkins and impurities, reduce clogging of the filter screen 15, reduce the working efficiency of the gas turbine 24, and improve cleaning efficiency.
