[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 4 As shown, a dust removal and ash conveying device for a thermal power plant includes multiple ash conveying pipes 1, which are used to transport dust from the dust removal equipment in the thermal power plant to a preset location. It should be noted that the multiple ash conveying pipes 1 can be connected to one or more thermal power plant dust removal devices as needed, and there are no restrictions on this. Specifically, the ash conveying pipe 1 is a hollow cylindrical body with openings at both ends. An ash inlet 11 is provided on one side of the ash conveying pipe 1 for connection to the thermal power plant dust removal equipment.

[0023] Each ash conveying pipe 1 is rotatably connected to a dust removal component for cleaning dust adhering to and accumulating on the inner wall of the ash conveying pipe 1. In this embodiment, the dust removal component includes a stirring assembly 2, a power unit 4, a threaded rod 3, and a scraper assembly 5. The stirring assembly 2 is rotatably disposed at one end of the ash conveying pipe 1, and the threaded rod 3 is coaxially disposed inside the ash conveying pipe 1. One end of the threaded rod 3 is fixedly connected to the stirring assembly 2, and the other end of the threaded rod 3 extends away from the stirring assembly 2. The power unit 4 drives the threaded rod 3 to rotate, thereby driving the stirring assembly 2 to rotate. The scraper assembly 5 is screwed onto the threaded rod 3. A sliding groove 12 is formed on the inner wall of the ash conveying pipe 1 along the axial direction of the ash conveying pipe 1, and the scraper assembly 5 is slidably connected to the sliding groove 12.

[0024] During implementation, the power unit 4 drives the threaded rod 3 and the stirring assembly 2 fixedly connected to the threaded rod 3 to rotate. At this time, the forward or reverse rotation of the threaded rod 3 drives the scraper assembly 5, which is screwed to the threaded rod 3 and simultaneously slidably connected to the ash conveying pipe 1, to move along the axial direction of the threaded rod 3. In this way, the scraper assembly 5 cleans the inner wall of the ash conveying pipe 1, and the clumps of dust that are cleaned can be broken up by the stirring assembly 2, so that the ash conveying pipe 1 can quickly discharge the dust by the externally supplied compressed air, thus avoiding the clumps of dust from clogging the ash conveying pipe 1.

[0025] Specifically, the mixing assembly 2 includes a rotating ring 21 and multiple mixing rods 22. The rotating ring 21 is a hollow circular ring that is rotatably connected to the inner wall of the ash conveying pipe 1. The rotating ring 21 is fixedly connected to the threaded rod 3 through multiple mixing rods 22. That is, multiple mixing rods 22 are arranged between the rotating ring 21 and the threaded rod 3, and the multiple mixing rods 22 are evenly arranged along the circumference of the threaded rod 3. The two ends of the multiple mixing rods 22 are fixedly connected to the threaded rod 3 and the rotating ring 21, respectively.

[0026] Please see Figure 3 As shown, in this embodiment, a first retaining ring 13 protrudes from the inside of the ash conveying pipe 1, and a second retaining ring 6 is detachably connected to one end of the ash conveying pipe 1. The stirring assembly 2 is housed between the first retaining ring 13 and the second retaining ring 6 and is rotatably connected to the inner wall of the ash conveying pipe 1. Specifically, the second retaining ring 6 includes a ring body 61 and a plurality of fixing blocks 62 evenly distributed on the outer circumferential surface of the ring body 61. Flanges 7 for connecting to other pipes are fixed at both ends of the ash conveying pipe 1, and a plurality of relief grooves 71 are recessed on the flanges 7 near the first retaining ring 13. The plurality of fixing blocks 62 correspond one-to-one with the plurality of relief grooves 71 and are fixed in the plurality of relief grooves 71 by a plurality of connecting parts 8. Preferably, the connecting parts 8 are screws or bolts.

[0027] During implementation, the staff first places the mixing component 2 inside the ash conveying pipe 1, so that one end of the mixing component 2 abuts against the first retaining ring 13. Then, the multiple fixing blocks 62 of the second retaining ring 6 are inserted into the multiple relief grooves 71. Next, the second retaining ring 6 is fixedly connected to the flange 7 through the connector 8. At this time, the mixing component 2 is accommodated between the first retaining ring 13 and the second retaining ring 6 and is rotatably connected to the inner wall of the ash conveying pipe 1.

[0028] Please see Figure 2As shown, in this embodiment, the power unit 4 includes a first helical gear 41 fixedly sleeved on one end of the threaded rod 3 near the stirring assembly 2. A shaft 42 for connecting to an external motor (not shown) passes through one side of the ash conveying pipe 1. A second helical gear 43, meshing with the first helical gear 41, is fixedly sleeved on one end of the shaft 42 inside the ash conveying pipe 1. In implementation, when the external motor is started, it drives the shaft 42 to rotate. This causes the second gear fixedly sleeved on the shaft 42 to drive the first gear fixedly sleeved on the outside of the threaded rod 3 to rotate synchronously, thereby causing the threaded rod 3 to rotate synchronously.

[0029] Please see Figure 4 Simultaneously combined Figure 2 As shown, in this embodiment, the scraper assembly 5 includes a sleeve 51, a movable ring 52, multiple connecting rods 53, and a slider 54. The sleeve 51 is screwed to the outside of the threaded rod 3. The outer wall of the movable ring 52 abuts against the inner wall of the ash conveying pipe 1 and is used to scrape off the clumps of dust adhering to the inner wall of the ash conveying pipe 1. Multiple connecting rods 53 are arranged between the sleeve 51 and the movable ring 52 and are evenly distributed along the circumference of the sleeve 51. The two ends of the multiple connecting rods 53 are fixedly connected to the sleeve 51 and the movable ring 52, respectively. That is, the sleeve 51 and the movable ring 52 are fixedly connected by multiple connecting rods 53. The slider 54 is fixed on one side of the movable ring 52 and is slidably connected to the slide groove 12. By setting the slider 54 and the slide groove 12, the scraper assembly 5 is prevented from rotating synchronously during the rotation of the threaded rod 3, which would prevent the scraper assembly 5 from moving axially along the threaded rod 3.

[0030] In a specific implementation of this utility model, the worker places the dust removal component inside the ash conveying pipe 1 and abuts one end of the stirring assembly 2 against the first retaining ring 13. Then, the second retaining ring 6 is fixedly connected to the flange 7. At this time, the stirring assembly 2 is housed between the first retaining ring 13 and the second retaining ring 6 and is rotatably connected to the inner wall of the ash conveying pipe 1. When it is necessary to clean the dust that has accumulated in the ash conveying pipe 1, the external device (motor) is connected to the shaft 42 of the power unit 4. The power unit 4 then drives the threaded rod 3 and the stirring assembly 2 fixedly connected to the threaded rod 3 to rotate, while simultaneously driving the scraper assembly 5 to move along the axial direction of the threaded rod 3 to clean the inner wall of the ash conveying pipe 1. The dust that has been cleaned can be broken up by the stirring assembly 2, which facilitates the rapid discharge of dust from the ash conveying pipe 1 by compressed air supplied from the outside, thus preventing the dust from clogging the ash conveying pipe 1.

[0031] The above description is only a preferred embodiment of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
