Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cyclone separators for ash circulation, and specifically relates to an ash circulation system. Background Art
[0002] In the boiler processing and production of materials, an ash circulation system is generally adopted. The ash circulation can be divided into two forms: internal circulation and external circulation. The external circulation mainly consists of components such as cyclone separators, return valves, external beds, and return pipes. Two cyclone separators are arranged on the left and right side walls of the upper part of the furnace chamber respectively, so that the incoming flue gas is centrifugally separated, and most of the solid particles in the gas-solid two-phase flow are separated.
[0003] In the existing cyclone separator, there are internal rotation and external rotation in a spiral shape. The internal rotation makes the gas move upward, and the external rotation makes the solid particles move downward. After long-term operation, solid particles and other impurities adhere to the inner wall of the cyclone separator, affecting the separation effect. Therefore, we propose an ash circulation system. Summary of the Invention

Detailed implementation manners
[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention. Embodiment
[0027] Please refer to Figures 1 - 4, A gray circulation system in the figure includes a body 1. Inside the body 1, there is an inner rotation part 2 and an outer rotation part 3. An air inlet 4 is provided on the side of the body 1, and a gas-phase air outlet 5 and a solid-phase air outlet 6 are respectively provided at the upper and lower ends of the body 1. It also includes a cleaning component 7 for cleaning the inner wall of the body 1, and the cleaning component 7 is arranged inside the body 1. A regulating component 20 for cooperating with the cleaning component 7 to contract and not clean when moving upward and extend to clean when moving downward is arranged on the cleaning component 7.
[0028] In this embodiment, the mixture enters the body 1 through the air inlet 4. Under the action of the outer rotation part 3, the solid particles in the mixture make the solid particles rotate downward along the inner wall of the body 1 and flow out through the solid-phase air outlet 6. And the gas in the mixture, under the action of the inner rotation part 2, rotates upward along the central axis position of the body 1 and flows out through the gas-phase air outlet 5. When impurities adhere to the inner wall of the body 1, control the cleaning component 7 to rotate and scrape the impurities on the inner wall of the body 1. And through the action of the regulating component 20, when the cleaning component 7 moves upward, it does not act on the inner wall of the body 1, and when the cleaning component 7 moves downward, it acts on the inner wall of the body 1. Embodiment
[0029] Please refer to Figures 1 - 4 , A gray circulation system in the figure includes a body 1. Inside the body 1, there is an inner rotation part 2 and an outer rotation part 3. An air inlet 4 is provided on the side of the body 1, and a gas-phase air outlet 5 and a solid-phase air outlet 6 are respectively provided at the upper and lower ends of the body 1. It also includes a cleaning component 7 for cleaning the inner wall of the body 1, and the cleaning component 7 is arranged inside the body 1. A regulating component 20 for cooperating with the cleaning component 7 to contract and not clean when moving upward and extend to clean when moving downward is arranged on the cleaning component 7.
[0030] Please refer to Figures 2 - 4 , In the figure, the cleaning component 7 includes a motor 8 fixedly connected to the body 1. The output shaft of the motor 8 is fixedly connected with a rotating rod 9 that penetrates into the gas-phase air outlet 5. A telescopic component 10 is slidably fitted on the outer surface of the rotating rod 9. The other end of the telescopic component 10 is rotatably connected with a scraping plate 11 that fits against the inner wall of the body 1. The rotating rod 9 is located at the central axis position of the inner rotation part 2 and the outer rotation part 3.
[0031] Please refer to Figures 4 - 5 and Figure 8, the telescopic component 10 in the figure includes two limit plates 13 fixedly connected to the rotating rod 9. A sliding rod 14 is slidably fitted between the two limit plates 13. One end of the sliding rod 14 is fixedly connected to a first limit ring 15 sleeved and fitted with the inner rotation 2. A second limit ring 16 is sleeved on the outer surface of the outer rotation 3. The outer surface of the first limit ring 15 is fixedly connected to a first telescopic rod 17. The other end of the first telescopic rod 17 is slidably connected to the second limit ring 16. A sleeve rod 18 is fixedly connected to the part of the second limit ring 16 close to the inner wall of the machine body 1. A sleeve 19 rotatably connected to the scraping plate 11 is sleeved on the outer surface of the sleeve rod 18. The sleeve 19 and the sleeve rod 18 are connected by a spring.
[0032] Please refer to Figure 4 and Figures 9 - 10 , the adjustment component 20 in the figure includes a second telescopic rod 21 fixedly connected to the sleeve 19. A third telescopic rod 22 is fixedly connected to the second limit ring 16. A fourth telescopic rod 23 is fixedly connected to the first limit ring 15. A first rack 24 is fixedly connected to the outer surface of the fourth telescopic rod 23. A fixing plate 25 is fixedly connected to the outer surface of the third telescopic rod 22. The first rack 24 meshes with a first gear 26 rotatably connected to the fixing plate 25. The first gear 26 meshes with a second gear 27 rotatably connected to the fixing plate 25. The second gear 27 meshes with a second rack 28 fixedly connected to the second telescopic rod 21.
[0033] Among them, a plurality of rollers are embedded on the side of the scraping plate 11.
[0034] In this embodiment, when the motor 8 is started, the rotating rod 9 is driven to rotate. Under the action of the limit plates 13, the sliding rod 14 is driven to rotate. The sliding rod 14 drives the first limit ring 15 to rotate along the inner rotation 2 (the diameter of the inner rotation 2 remains unchanged), and through the telescopic rod, the second limit ring 16 is driven to rotate along the outer rotation 3. Since the diameter of the outer rotation 3 changes, the telescopic rod movably connected to the second limit ring 16 makes an adaptive adjustment. The second limit ring 16 drives the sleeve rod 18, the spring and the sleeve 19 to rotate, so that the scraping plate 11 closely adheres to the inner wall of the machine body 1 for scraping movement. When the scraping plate 11 moves upward, the distance between the first limit ring 15 and the second limit ring 16 increases, and the first rack 24 and the first gear 26 make relative movement. The first gear 26 rotates counterclockwise, driving the second gear 27 to rotate clockwise. The second gear 27 drives the second rack 28 to move away from the inner wall of the machine body 1, thereby driving the sleeve 19 and the scraping plate 11 away from the inner wall of the machine body 1, avoiding the scraping plate 11 from being separated from the inner wall when the scraping plate 11 moves upward, and preventing solid particles from entering the gas phase air outlet 5. Among them, the scraping plate 11 and the sleeve 19 maintain an angle (not shown in the figure) consistent with the inclination angle of the bottom of the machine body 1 through a torsion spring. On the contrary, when the scraping plate 11 moves upward, the scraping plate 11 and the sleeve 19 move toward the inner wall of the machine body 1, so that the scraping plate 11 closely adheres to the inner wall of the machine body 1 to complete the cleaning work.
