DETAILED DESCRIPTION
[0014] The utility model will be further explained in connection with the drawings and examples, but it is not as the basis for limiting the utility model.
[0015] Example. A kind of boiler combustion system real-time ash removal device, constitutes as shown in Figs. 1-3 The first driving mechanism 1 is connected to the bracket 2 on one side, and the bracket 2 is arranged on the inside of the air preheater box body and can move along the length direction of the air preheater, the bracket 2 is provided with the guide rail 6 on one side, and the guide rail 6 is fixedly arranged in the air preheater box body and is arranged along the length direction of the air preheater, the second driving mechanism 3 is arranged on the bracket 2, the moving rod 4 is arranged on one side of the second driving mechanism 3 and can move along the width direction of the air preheater, and the moving rod 4 is provided with a plurality of racks 5 perpendicular to the air preheater pipeline.
[0016] The bracket 2 includes two groups of supporting beams 7 arranged along the length direction of the air preheater, and the supporting beams 7 are provided with two groups of mounting beam groups corresponding to the moving rod 4, the mounting beam group includes two parallel mounting beams 8, the mounting beams 8 of the mounting beam group are provided with gaps that can pass through the rack 5 and guide the rack 5, the end of the mounting beam 8 is provided with the connecting block 9 connecting the two mounting beams 8, the upper end of the connecting block 9 is provided with the vertically arranged guide groove 10, and the supporting beam 7 and the mounting beam 8 are provided with the inclined support 11.
[0017] The moving rod 4 is provided with a plurality of mounting blocks 13 for mounting the rack, and the end of the moving rod 4 is arranged in the guide groove 10.
[0018] The second driving mechanism 3 comprises a plurality of mounting racks 12 arranged on the upper side of the mounting beam group, and a cylinder 14 is arranged at the upper end of the mounting rack 12 to drive the movement of the moving rod 4.
[0019] The working principle of the present application is that the bracket 2 is driven by the first driving mechanism 1 to move along the guide rail 6 arranged in the air preheater box, so that the bracket 2 can move along the length direction of the air preheater. The second driving mechanism 3 is arranged on the bracket 2, which can drive the movement of the moving rod 4 and the rack 5 on the moving rod 4 along the width direction of the air preheater, so as to better clean the impurities on the surface of the air preheater pipeline. The present application uses a rack to scrape off the impurities on the surface of the air preheater pipeline. Compared with the commonly used scraper, when the rack is used to clean the surface of the air preheater pipeline, the dust and impurities can quickly fall through the gap between the teeth, and the cleaning effect is good. Moreover, part of the dust and impurities will have certain viscosity and easily adhere to the surface of the air preheater pipeline. When the rack is used to clean the surface of the air preheater pipeline, the amount of impurities adhered to the contact surface between the rack and the air preheater pipeline is small, while the commonly used scraper is easy to adhere to the impurities on the contact surface between the scraper and the air preheater pipeline, and the cleaning effect is poor. The gap between the two mounting beams 8 of the bracket mounting beam group of the present application can limit the movement of the rack 5, the guide groove 10 in the connecting block 9 can further guide and limit the movement of the rack and the moving rod 4, and prevent the rack from swinging during movement, so that the reliability is good. During the movement of the rack, an accelerated vortex can also be formed to drive the ash accumulated on the pipe wall to fall off, so that the pipe wall of the air preheater can maintain a certain degree of cleanliness, and the ash will not be blocked between the pipes.
