Description

Technical Field

[0002] A gas turbine is a power machine that uses the combustion of fuel and air to generate high-temperature, high-pressure gas that drives a turbine to rotate. Its working principle is to generate power through the compression, combustion, and expansion of air. It is widely used in aero engines, power plants, and ships. Gas turbines have advantages such as high efficiency, fast response, and adjustable output power. Compared with traditional steam turbines, gas turbines start faster, are smaller, and have higher fuel efficiency, making them an important part of the modern energy industry.

[0003] An air filtration device is a device that removes impurities, pollutants, and harmful substances from the air using physical or chemical methods. Common filter materials include filter screens, activated carbon, and HEPA filter media, which can effectively filter dust, bacteria, viruses, gaseous pollutants, etc. Air filtration devices are widely used in household air conditioners, industrial ventilation systems, medical equipment, automobiles, and other fields to improve air quality and protect human health. Based on different filtration effects, air filtration devices can be divided into three levels: coarse, medium, and high efficiency.

[0004] Gas turbines must be used in conjunction with air filtration devices to filter the air entering the turbine, intercepting impurities and dust to prevent damage. To ensure that the efficiency of the gas turbine is not affected, the filter element in the air filtration device needs to be replaced regularly. However, in traditional air filtration devices, the filter element is fixed with bolts and nuts, and auxiliary tools are required for disassembly and replacement, which is time-consuming, labor-intensive, and inefficient. Therefore, an air filtration device for gas turbines is proposed to solve the above problems. Utility Model Content

The ropes 8 are used to pull the slide plate 10 to move. The spring 9 is used to make the slide plate 10 automatically return to its original position. The insert rod 11 can only move in a specified direction under the limitation of the fixing ring 6 and will not move or wobble. The slide plate 10 is fixed to its outside to prevent the insert rod 11 from exceeding its limits. The movement range causes detachment. The insertion rod 11 is used to fix the filter element 5 to the fixing rod 12, realizing quick assembly and disassembly. The fixing rod 12 is used to connect the filter element 5. The insertion hole 13 is used to cooperate with the insertion rod 11 to fix the filter element 5. The rope 8 is externally slidably connected to the inside of the fixing ring 6. The inside of the rope 8 is fixedly connected to the outside of the slide plate 10, so that when the rope 8 moves, it can pull the slide plate 10 to move.

The outside of the slide plate 10 is slidably connected to the inner wall of the fixing ring 6. The outside of the insertion rod 11 is slidably connected to the inside of the fixing ring 6. The fixing ring 6 simultaneously restricts the movement direction of the slide plate 10 and the insertion rod 11. The outside of the insertion rod 11 is inserted into the inside of the insertion hole 13 to keep the filter element 5 stable. The inside of the filter element 5 is slidably connected to the outside of the fixing rod 12 to restrict the movement direction of the filter element 5.

[0036] Reference Figure 2 , Figure 5 , Figure 6The sealing assembly includes a baffle 14, the upper side of which is fixedly connected to the bottom end of the fixing rod 12.

The second spring 15 is used to push the baffle 14 to reset. The fixing block 17 is used to support the sealing assembly. The housing 16 is used to connect and protect the internal parts. The fixing block 17 is externally fixedly connected to the inside of the fixing housing 2 to keep the fixing block 17 stable. The baffle 14 is externally slidably connected to the inner wall of the housing 16 to limit the movement direction of the baffle 14. The fixing rod 12 is externally slidably connected to the inside of the fixing block 17 to limit the movement direction of the fixing rod 12.

[0037] Working principle: When the gas turbine body 1 is working, it draws in air from the top and compresses it into the combustion chamber. Simultaneously, the air is filtered by the filter element 5, trapping impurities and dust to prevent damage to the gas turbine body 1. After a period of use, the filter element 5 needs to be replaced. By rotating the rotating ring 7, the rope 8 pulls the sliding plate 10, compressing the spring 9, causing the insertion rod 11 to retract into the fixing ring 6 and disengage from the fixing rod 12. At this point, the filter element 5 is unlocked. The filter element 5 can then be removed from the fixing rod 12. Next, the rotating ring 7 on the new filter element 5 is rotated, and the filter element... 5. Slide the filter element into the fixing rod 12, then pull the fixing rod 12 to compress the baffle 14 and spring 15. Then, under the limit of the fixing ring 6, spring 9 will immediately push the slide plate 10 to push out the insertion rod 11 and insert it into the insertion hole 13, fixing the filter element 5 on the fixing rod 12. Then, align the sealing ring 4 with the groove on the fixing shell 2 and insert it. At this time, under the support of the fixing block 17, spring 15 will push the baffle 14 to pull the fixing assembly, pressing the filter element 5 onto the fixing shell 2 and cooperating with the sealing ring 4, thus achieving quick replacement sealing, saving time and effort, and making operation convenient.
