Abstract
The invention provides an adjustable coal feeder connecting device of a circulating fluidized bed boiler coal feeding system, which comprises a coal drop pipe, a first connecting pipe, a second connecting pipe, an insertion hole, a fixed cover and a rotatably connected conveying pipe Structure, pluggable sliding speed control plate structure, observable cleaning tube structure, pushable isolation plate structure, inclined T-shaped cover, U-shaped bracket, jacking bolt, support tube, support rod, first lock nut, support seat and the ventilation pipe, the lower end of the first connecting pipe is bolted to the middle position of the upper end of the coal falling pipe. The present invention is arranged to push the isolation plate, the push pipe, the extension rod, the coal falling pipe and the first connecting pipe, which is beneficial to move the push isolation plate to the right side of the lower end of the first connecting pipe during the use process, preventing the use of In the middle, the first connecting pipe is isolated from the burning coal in the equipment by pushing the isolation plate, so as to prevent the burning of the coal in the first connecting pipe from affecting the work during use.
Description
technical field [0001] The invention belongs to the technical field of a coal feeder takeover device, and in particular relates to an adjustable coal feeder takeover device of a coal feeding system of a circulating fluidized bed boiler. Background technique [0002] The structure of the coal drop pipe device of the existing circulating fluidized bed boiler coal feeding system is specifically arranged to ensure that the coal can smoothly enter the furnace and reduce the resistance, and the coal drop tube forms an included angle of 55° with the horizontal direction. [0003] However, in the existing coal feeder takeover device, it is inconvenient to adjust the angle of the feeding equipment in the process of use, it is inconvenient to adjust the feeding speed, and it is easy to cause coal combustion in the pipeline and inconvenience during the coal feeding process. Issues with pipe cleaning. [0004] Therefore, it is very necessary to invent an adjustable coal feeder takeover...
