Novel filling device for filling bed charge of boiler

Abstract

The invention provides a novel filling device for filling bed charge of a boiler. The device comprises a lifter. A lifter feeding hopper is mounted at the bottom of the lifter, a middle splitting valve is mounted on the top of the lifter, a plurality of splitting pipelines are mounted below the middle splitting valve, and each splitting pipeline is connected to a conveyor belt. When the novel filling device for filling the bed charge of the boiler is used, the bed charge of a circulating fluidized bed boiler is poured into the lifter feeding hopper through first, the bed charge is lifted to aposition above a mechanical system through the lifter, the bed charge falls in front of the middle splitting valve by means of gravity, the bed charge flows to the boiler by controlling the angle of the middle splitting valve, and the material falls onto the conveyor belts heading for different boilers through the middle splitting valve, is then conveyed to a coal feeder horizontally through the conveyor belts and is then fed into hearths. The novel filling device is simple and reliable in structure, skillful in design, high in filling speed and high in work efficiency.

Description

technical field [0001] The invention relates to a bottom material filling mechanical system, in particular to a novel filling device for boiler bottom material filling. Background technique [0002] At present, most of the filling systems for circulating fluidized bed boiler bottom materials in domestic coal-fired power plants are manual, which is time-consuming and labor-intensive. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel filling device for boiler bottom material filling. [0004] A new type of filling device for boiler bottom material filling to achieve the purpose of the present invention includes a hoist, a bucket elevator feed hopper is installed at the bottom of the hoist, and an intermediate material distribution valve is installed on the top of the hoist. A plurality of material distribution pipelines are installed below the middle material distribution valve, and each material distribution pip...
