Abstract

The invention provides an adjustable coal feeder pipe connecting device of a circulating fluidized bed boiler coal feeding system. The adjustable coal feeder pipe connecting device comprises a coal falling pipe, a first connecting pipe, a second connecting pipe, an inserting hole, a fixing cover, a rotatable connecting conveying pipe structure, an inserting sliding speed adjusting plate structure,an observable cleaning pipe structure, a pushable isolation plate structure, an inclined T-shaped cover, a U-shaped support, a puller bolt, a supporting pipe, a supporting rod, a first locking nut, asupporting base and a ventilation pipe, wherein the lower end of the first connecting pipe is in bolt connection to the middle position of the upper end of the coal falling pipe. Through the arrangement of a pushable isolation plate, a pushing pipe, an extending rod, the coal falling pipe and the first connecting pipe, the pushable isolation plate can be better moved to the right side of the lower end of the first connecting pipe in the using process, the situation that in the using process, the first connecting pipe and burning coal briquettes in equipment are isolated through the pushable isolation plate is prevented, and the situation that in the using process, the coal briquettes in the first connecting pipe burn, and work is affected is prevented.

Description

technical field [0001] The invention belongs to the technical field of coal feeder connection devices, and in particular relates to an adjustable coal feeder connection device of a circulating fluidized bed boiler coal feeding system. Background technique [0002] The structure of the coal drop pipe device of the existing circulating fluidized bed boiler coal feeding system is specifically designed to ensure that the coal can enter the furnace smoothly and reduce resistance. The coal drop pipe has an angle of 55° with the horizontal direction. [0003] However, the existing coal feeder connection device still has the disadvantages of inconvenient adjustment of the angle of the feeding equipment during use, inconvenient adjustment of the speed of feeding, and the coal burning in the pipeline is easy to cause and inconvenient during the coal feeding process. Problems with pipe cleaning. [0004] Therefore, it is very necessary to invent a coal feeder connecting device of an a...
