Detailed Description

Examples

The ash removal device for the burner of the sleeve kiln of the embodiment, as shown in fig. 1, comprises: the ash removing box 1, the ash settling bucket 2 and the ash raking rod 9. One end of the ash removing box 1 is provided with an ash removing opening; a furnace door 12 of the sleeve kiln extends into the ash removal box 1 from an ash removal opening, and the furnace door 12 and the ash removal opening are sealed; one end of the ash scraping rod 9 is positioned in the ash removing box 1, and the ash scraping plate 7 is arranged at the end; the ash scraping plate 7 is hinged at one end of the ash scraping rod 9; the ash scraping plate 7 can swing towards the ash scraping rod 9; the hinged shaft of the ash scraping plate 7 and the ash scraping rod 9 is provided with a limit position for limiting the swing limit position of the ash scraping plate 7; the swing limit position of the ash removing plate 7 is a position where the included angle between the ash removing plate 7 and the ash removing rod 9 is less than or equal to 90 degrees.

The other end of the ash raking rod 9 is connected with a cylinder 5; the cylinder 5 can drive the ash scraping rod 9 to move back and forth so as to drive the ash scraping plate 7 to enter and exit the ash box 1 from the ash cleaning port. The cylinder 5 is arranged on the lower combustion chamber platform 13 through a mounting frame 14, a cylinder base 6 is further arranged on the mounting frame 14, and the cylinder 5 is fixed on the cylinder base. The piston rod of the air cylinder 5 is connected with the ash raking rod 9, the roller 8 is further arranged on the mounting frame 14 to support the ash raking rod 9, the stability of the ash raking rod 9 is improved, meanwhile, the moving track of the ash raking rod 9 can be limited, and the joint of the ash raking rod 9 and the ash cleaning box 1 is sealed, so that hot air circulation is avoided.
