Technical Field

[0001] This invention relates to the field of heat recovery technology, specifically to a gas heat recovery turbine device. Background Technology

[0002] With increasing emphasis on energy conservation and emission reduction, the technology of generating electricity using waste heat and pressure from gas has become an inevitable development trend.

[0003] In the prior art, patent CN220791314U discloses a centripetal turbine adjustable guide vane for waste heat and pressure energy recovery, including a hub, a casing at the outer edge of the hub, and multiple guide vanes arranged in a circumferential pattern between the hub and the casing. Each guide vane includes four parts: a leading edge, a suction surface, a pressure surface, and a trailing edge. The leading edge of each guide vane is arc-shaped and has a large streamline curvature radius, while the trailing edge has a small radius. Each guide vane is inverted teardrop shape, and a constricted gas flow channel is formed between the suction surface of each guide vane and its adjacent pressure surface.

[0004] However, during the operation of existing gas heat recovery turbine devices, a large amount of dust accumulates on the surface of the turbine blades. This dust affects the rotation of the turbine blades, resulting in low recovery efficiency. Summary of the Invention

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

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas heat recovery turbine device, comprising: The outer casing has an air vent at one end and a generator at the other end. Inside the casing is a cleaning plate with a cleaning brush on its surface and a ring fixed thereon. Inside the casing is a limit rod connected to the ring and a connecting rope. Inside the casing is a rotating shaft with a cylinder inside it. At the end of the cylinder is a piston rod connected to the connecting rope.

[0007] Preferably, a vertical plate is fixed inside the outer casing, and a rotating shaft is provided inside the outer casing. One end of the rotating shaft is inserted into the inside of the vertical plate, and the end of the rotating shaft can rotate inside the vertical plate. The other end of the rotating shaft is connected to the rotor inside the generator.

[0008] Preferably, the surface of the rotating shaft is fixed with fan blades, and multiple sets of fan blades are provided. The fan blades rotate with the rotating shaft. The surface of the fan blades is fixed with fins, and multiple sets of fins are provided. The multiple sets of fins are evenly distributed on the surface of the fan blades, and the fins rotate with the fan blades.

[0009] Preferably, a first rotating ring is inserted inside the outer shell, and the first rotating ring can rotate on the inner wall surface of the outer shell. A second rotating ring is inserted into the outer shell, and the second rotating ring can rotate on the inner wall surface of the outer shell. A through groove is opened inside the second rotating ring, and a connecting rope is inserted into the through groove, and the connecting rope can move in the through groove.

[0010] Preferably, the inner wall of the outer shell is fixed with a limiting rod, and multiple sets of limiting rods are provided. One end of the limiting rod is connected to the surface of the first rotating ring, and the other end is connected to the surface of the second rotating ring. The limiting rod rotates with the first rotating ring and the second rotating ring. A ring is fixed on the surface of the cleaning plate and is sleeved on the surface of the limiting rod. The ring can move on the surface of the limiting rod, and the cleaning plate moves with the ring.

[0011] Preferably, a telescopic rod is inserted into the surface of the cleaning plate, with both ends of the telescopic rod inserted into the interior of two sets of cleaning plates respectively. A spring is installed inside the cleaning plate, and the spring is connected to the end of the telescopic rod. The spring inside the cleaning plate exerts a pulling force on the telescopic rod, so that the telescopic rod is located inside the cleaning plate. A cleaning brush is installed on the surface of the cleaning plate, and the cleaning brush moves with the cleaning plate.

[0012] Preferably, a connecting rope is connected to the surface of the ring, and the connecting rope drives the ring to move.

[0014] Preferably, the end of the outer casing is connected to a gas discharge device, allowing gas to enter the interior of the outer casing. The gas drives the fan blades and fins to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the rotor inside the generator to rotate, allowing the gas inside the outer casing to be discharged through the vent.

[0015] Preferably, as the cleaning plate moves along the limiting rod, the cleaning brush on the surface of the cleaning plate can contact the fins on the surface of the fan blade, and the cleaning brush cleans the dust on the surface of the piston rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The gas introduced in this invention enters the interior of the casing, causing the fins and blades to rotate. The blades and fins drive the rotating shaft to rotate, which in turn drives the rotor inside the generator to rotate, thus generating electricity. When a large amount of dust remains on the surface of the fins, a piston rod is driven by a cylinder to move laterally. The piston rod moves inside the rotating shaft, pulling the connecting rope. This tension causes the connecting rope to pull the ring to move, which in turn moves the cleaning plate. The cleaning plate is equipped with cleaning brushes on its surface. The cleaning plate moves along the limit rod, and the cleaning brushes clean the fins. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 6 The present invention provides a technical solution: Example 1: A gas heat recovery turbine device includes: a housing 1, with an outlet 2 at one end of the housing 1, a generator 3 at one end of the housing 1, a cleaning plate 15 inside the housing 1, a cleaning brush 16 on the surface of the cleaning plate 15, a ring 13 fixed to the surface of the cleaning plate 15, a limit rod 12 inside the housing 1, a connecting rope 11 connected to the ring 13, a rotating shaft 6 inside the housing 1, a cylinder 17 inside the rotating shaft 6, a piston rod 18 at the end of the cylinder 17, the piston rod 18 connected to the connecting rope 11, and a connecting rod 12 fixed to the surface of the ring 13. The connecting rope 11 drives the ring 13 to move. A cylinder 17 is installed inside the rotating shaft 6 and is fixed inside the rotating shaft 6. A piston rod 18 is installed at the end of the cylinder 17. The cylinder 17 drives the piston rod 18 to move laterally. The piston rod 18 can move laterally inside the rotating shaft 6. The piston rod 18 pulls the connecting rope 11, so that the connecting rope 11 is pulled. The connecting rope 11 pulls the ring 13 to move. The ring 13 drives the cleaning plate 15 to move.

[0026] Example 2: Based on Example 1, a vertical plate 4 is fixed inside the outer casing 1, and a rotating shaft 6 is installed inside the outer casing 1. One end of the rotating shaft 6 is inserted into the interior of the vertical plate 4, and the end of the rotating shaft 6 can rotate inside the vertical plate 4. The other end of the rotating shaft 6 is connected to the rotor inside the generator 3. A slot 19 is opened on the surface of the rotating shaft 6, and multiple sets of slots 19 are provided. A connecting rope 11 is inserted into the slot 19, and the end of the connecting rope 11 is connected to the end of the piston rod 18. The connecting rope 11 moves with the piston rod 18. The end is connected to a gas discharge device, allowing gas to enter the interior of the outer casing 1. The gas drives the fan blades 7 and fins 8 to rotate, which in turn drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the rotor inside the generator 3 to rotate, and the gas inside the outer casing 1 can be discharged from the air outlet 2. During the rotation of the rotating shaft 6, since the second rotating ring 10 is connected to the rotating shaft 6 through a connecting rod, the second rotating ring 10 rotates with the rotating shaft 6 in the through groove 9, while the first rotating ring 5 rotates inside the outer casing 1, without obstructing the rotation of the fan blades 7 and fins 8.

[0027] Fan blades 7 are fixed on the surface of the rotating shaft 6. There are multiple sets of fan blades 7. The fan blades 7 rotate with the rotating shaft 6. Fins 8 are fixed on the surface of the fan blades 7. There are multiple sets of fins 8. The multiple sets of fins 8 are evenly distributed on the surface of the fan blades 7, and the fins 8 rotate with the fan blades 7.

[0028] A first rotating ring 5 is inserted inside the outer casing 1, and the first rotating ring 5 can rotate on the inner wall surface of the outer casing 1. A second rotating ring 10 is inserted into the outer casing 1, and the second rotating ring 10 can rotate on the inner wall surface of the outer casing 1. A through groove 9 is opened inside the second rotating ring 10, and a connecting rope 11 is inserted into the through groove 9, and the connecting rope 11 can move in the through groove 9. A limit rod 12 is fixed to the inner wall of the outer casing 1. Multiple limit rods 12 are provided. One end of the limit rod 12 is connected to the surface of the first rotating ring 5, and the other end is connected to the surface of the second rotating ring 10. The limit rod 12 rotates with the first rotating ring 5 and the second rotating ring 10. A ring 13 is fixed to the surface of the cleaning plate 15. The ring 13 is sleeved on the surface of the limit rod 12 and can move on the surface of the limit rod 12. The cleaning plate 15 moves with the ring 13. A telescopic rod 14 is inserted into the surface of the cleaning plate 15, and both ends of the telescopic rod 14 are respectively inserted into Inside the two sets of cleaning plates 15, springs are installed inside the cleaning plates 15. The springs are connected to the ends of the telescopic rods 14. The springs inside the cleaning plates 15 exert tension on the telescopic rods 14, so that the telescopic rods 14 are located inside the cleaning plates 15. Cleaning brushes 16 are provided on the surface of the cleaning plates 15. The cleaning brushes 16 move with the cleaning plates 15. As the cleaning plates 15 move along the limiting rods 12, the cleaning brushes 16 on the surface of the cleaning plates 15 can contact the fins 8 on the surface of the fan blades 7. The cleaning brushes 16 clean the dust on the surface of the piston rods 18. The cleaning plates 15 are provided with cleaning brushes 16. The cleaning plates 15 move along the limiting rods 12. The cleaning brushes 16 clean the fins 8. As the cleaning plates 15 move, the limiting rods 12 are tilted. The telescopic rods 14 extend out from inside the cleaning plates 15, which increases the diameter of the circle formed by the multiple sets of cleaning plates 15, making it easier to clean the surface of the next set of fins 8.

[0029] Gas enters the interior of the outer casing 1, causing the fins 8 and fan blades 7 to rotate. The fan blades 7 and fins 8 drive the rotating shaft 6 to rotate, which in turn drives the rotor inside the generator 3 to rotate, generating electricity. When a large amount of dust remains on the surface of the fins 8, the piston rod 18 is driven by the cylinder 17 to move laterally. The piston rod 18 moves inside the rotating shaft 6, pulling the connecting rope 11. This tension causes the connecting rope 11 to pull the ring 13 to move, which in turn moves the cleaning plate 15. The surface of the cleaning plate 15 is equipped with cleaning brushes 1. 6. The cleaning plate 15 moves along the limiting rod 12, and the cleaning brush 16 cleans the fins 8. As the cleaning plate 15 moves, the limiting rod 12 is tilted, and the telescopic rod 14 extends from the inside of the cleaning plate 15, which increases the diameter of the circle formed by the multiple sets of cleaning plates 15, making it easier to clean the surface of the next set of fins 8. During the rotation of the rotating shaft 6, since the second rotating ring 10 is connected to the rotating shaft 6 through the connecting rod, the second rotating ring 10 rotates with the rotating shaft 6 in the through groove 9, and the first rotating ring 5 rotates inside the outer shell 1, which will not obstruct the rotation of the fan blades 7 and the fins 8.
