Description

Technical Field

[0001] This utility model relates to exhaust pipe structure technology, specifically to an exhaust pipe for a novel turbine main unit. Background Technology

[0002] Turbine exhaust pipes are used to discharge high-temperature exhaust gases after power generation. They are generally made of high-temperature and corrosion-resistant materials and have good heat insulation and strength. With the development of society, there are more and more types of turbine exhaust pipes.

[0003] When filtering the exhaust gas discharged from the turbine main unit's exhaust pipe, the filtered debris is easily blocked inside the pipe by the filter screen. Due to the small size of the pipe, it is not easy for workers to clean the debris filtered inside the pipe. Therefore, there is an urgent need for a new type of turbine main unit exhaust pipe to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel exhaust pipe for a turbine main unit to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel exhaust pipe for a turbine main unit includes an exhaust pipe body. A fixing ring is slidably connected to the inner wall of the exhaust pipe body. A first filter screen is fixedly installed on the inner wall of the fixing ring. An auxiliary plate is fixedly installed on the surface of the first filter screen. A second filter screen is fixedly installed on the surface of the fixing ring. A collection cylinder is fixedly installed on the surface of the fixing ring. A fixing plate is fixedly installed on the surface of the auxiliary plate. Two push rods are slidably inserted inside the fixing plate. A retaining plate is fixedly installed at the ends of the two push rods that are far apart from each other. Two retaining grooves are formed on the surface of the exhaust pipe body. The inner walls of the retaining grooves are slidably connected to the retaining plates. Springs are fitted onto the arc surfaces of the push rods. The two ends of the springs are fixedly connected to a pull bracket and a retaining plate, respectively. The effect achieved by the above components is that the filtered dust can be collected when using the exhaust pipe of the turbine main unit, enabling convenient dust cleaning and achieving efficient dust treatment.

[0007] Preferably, the surface of the storage tube is provided with a storage groove, and the effect achieved by the above-mentioned components is that the storage groove can help the storage tube to collect dust.

[0008] Preferably, a sticker holder is fixedly installed at the end of the storage tube away from the fixing ring. The effect achieved by the above components is that dust can move along the sticker holder to the storage tube.

[0009] Preferably, a sealing sleeve is fixedly installed on the outer arc of the storage tube. The sealing sleeve is a rubber sleeve. The effect achieved by the above components is that the sealing sleeve can reduce the gap between the exhaust pipe and the storage tube.

[0010] Preferably, two support frames are fixedly installed on the surfaces of both card plates. Two rectangular grooves are formed on the surface of the fixed plate. The inner walls of the rectangular grooves are slidably connected to the support frames. The four support frames are arranged in pairs. Pull brackets are fixedly installed on the surfaces of the two sets of support frames. The effect achieved by the above components is that the sliding pull bracket drives the support frame to slide while the pull bracket slides, and the sliding support frame drives the card plate to slide while the card plate slides, thus achieving the effect of driving the card plate to slide.

[0011] Preferably, the fixing plate is internally threaded with a bolt, and the surface of the bolt is slidably fitted with a mounting plate. The surface of the mounting plate abuts against the tie rod. The effect achieved by the above components is as follows: when the bolt is rotated, the bolt moves towards the fixing plate by means of the thread. When the bolt moves, it drives the mounting plate to move. After the mounting plate moves a certain distance, the surface of the mounting plate presses against the two tie rods. At this time, the two tie rods are fixed together, and the clamping plate is also fixed, thus achieving the effect of restricting the sliding of the clamping plate.

[0012] Preferably, both of the two tie rods have balance grooves on their surfaces, and balance plates are slidably connected to the inner walls of the two balance grooves. The surfaces of the balance plates are fixedly connected to the mounting plate. The effect achieved by the above components is that the balance plates and balance grooves can prevent the balance plates from rotating when the bolts are rotated.

[0013] In the above technical solution, this utility model provides a novel exhaust pipe for a turbine main unit.

[0014] (1) By setting up components such as the first filter, the second filter and the collection tube, the filtered dust can be collected when using the exhaust pipe of the turbine host, which can conveniently clean the dust and achieve efficient dust treatment.

[0015] (2) By setting up components such as a support frame, a pull frame and a mounting plate, the card plate can be limited, making it difficult for the card plate to slide and making it convenient for workers to use the card plate to install and remove the fixing ring in the exhaust pipe.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-6As shown in the figure, the exhaust pipe of a novel turbine host provided by this utility model embodiment includes an exhaust pipe body 1. A fixing ring 2 is slidably connected to the inner wall of the exhaust pipe body 1. A first filter screen 3 is fixedly installed on the inner wall of the fixing ring 2. An auxiliary plate 4 is fixedly installed on the surface of the first filter screen 3. A second filter screen 18 is fixedly installed on the surface of the fixing ring 2. A storage cylinder 16 is fixedly installed on the surface of the fixing ring 2. A fixing plate 7 is fixedly installed on the surface of the auxiliary plate 4. Two push rods 14 are slidably inserted inside the fixing plate 7. A retaining plate 6 is fixedly installed at the ends of the two push rods 14 that are far apart from each other. Two slots 5 are opened on the surface of the exhaust pipe body 1. The inner wall of the slots 5 is slidably connected to the retaining plate 6. A spring 13 is sleeved on the arc surface of the push rod 14. The two ends of the spring 13 are fixedly connected to the pull frame 12 and the retaining plate 6, respectively. The effect achieved by the above components is that when using the exhaust pipe of the turbine host, the filtered dust can be collected, the dust can be easily cleaned, and the dust can be efficiently treated.

[0027] In this specific embodiment, the surface of the storage tube 16 is provided with a storage groove 21, which can help the storage tube 16 to collect dust.

[0028] In this specific embodiment, a mounting bracket 17 is fixedly installed at the end of the storage tube 16 away from the fixing ring 2, and dust can move to the storage tube 16 along the mounting bracket 17.

[0029] In this specific embodiment, a sealing sleeve 15 is fixedly installed on the outer arc of the storage tube 16. The sealing sleeve 15 is a rubber sleeve, which can reduce the gap between the exhaust pipe and the storage tube 16.

[0030] In this specific embodiment, two support frames 11 are fixedly installed on the surfaces of the two card plates 6. Two rectangular grooves 8 are opened on the surface of the fixed plate 7. The inner wall of the rectangular grooves 8 is slidably connected to the support frames 11. The four support frames 11 are arranged in pairs. Pull frames 12 are fixedly installed on the surfaces of the two sets of support frames 11. The pull frames 12 slide, and the support frames 11 slide at the same time as the pull frames 12 slide. The card plates 6 slide at the same time as the support frames 11 slide, thus achieving the effect of driving the card plates 6 to slide.

[0031] In this specific embodiment, the internal thread of the fixing plate 7 is connected to a bolt 10, and the surface of the bolt 10 is slidably fitted with a mounting plate 9. The surface of the mounting plate 9 abuts against the tie rod 12. When the bolt 10 is rotated, the bolt 10 moves towards the fixing plate 7 by means of the thread. While the bolt 10 moves, it drives the mounting plate 9 to move. After the mounting plate 9 moves a certain distance, the surface of the mounting plate 9 presses against the two tie rods 12. At this time, the two tie rods 12 are fixed together, and the clamping plate 6 is also fixed, thus achieving the effect of restricting the sliding of the clamping plate 6.

[0032] In this specific embodiment, the surfaces of the two tie rods 12 are provided with balance grooves 19, and the inner walls of the two balance grooves 19 are slidably connected with balance plates 20. The surface of the balance plates 20 is fixedly connected to the mounting plate 9. The balance plates 20 and the balance grooves 19 can prevent the balance plates 20 from rotating when the bolts 10 rotate.

[0033] Working principle: When using the exhaust pipe, debris is filtered by the first filter screen 3 and the second filter screen 18, and the filtered debris is collected in the collection groove 21 of the collection cylinder 16. When it is necessary to clean these debris, slide the two pull brackets 12. The two pull brackets 12 slide towards each other. While the pull brackets 12 are sliding, they also drive the clamping plate 6 to slide. After the clamping plate 6 has slid a certain distance, it slides out of the inner wall of the clamping groove 5 on the exhaust pipe. Then, rotate the bolt 10. The bolt 10 moves towards the fixing plate 7 with the help of the thread. While the bolt 10 is moving, it also drives the mounting plate 9 to move. After the mounting plate 9 has moved a certain distance, the surface of the mounting plate 9 presses against the two pull brackets 12. At this time, the two pull brackets 12 are fixed together, and the clamping plate 6 is also fixed. At this time, the fixing ring 2 can be removed, and the collection cylinder 16 can also be removed. Then, the debris filtered by the filter screen can be processed.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
