Abstract

The invention discloses a secondary coal feeding device suitable for a narrow space, and relates to the technical field of coal feeding devices. The coal feeder comprises a controller, a first coal feeder body, a frame body and a second coal feeder body arranged on the frame body, the second coal feeder body is located above the first coal feeder body, a discharging port of the second coal feeder body is connected and communicated with a discharging port of the first coal feeder body, the controller is electrically connected and communicated with the first coal feeder body, and the controller is electrically connected and communicated with the second coal feeder body; by means of the controller, the first coal feeder, the second coal feeder and the like, the coal feeding distance of the coal feeders is prolonged under the influence of obstacles.

Description

technical field [0001] The invention relates to the technical field of coal feeding devices, in particular to a secondary coal feeding device suitable for narrow spaces. Background technique [0002] In recent years, with the poor coal quality and the increasing demand for deep peak shaving of units, the hazards of coal bunkers and broken coal are becoming more and more serious. The load is blocked, which seriously affects the economy of the unit and the flexibility of deep peak regulation. It is imperative to transform coal bunkers into small sub-storages. During the renovation process, due to changes in the inclination angle of the coal bunker, the center of the coal feeder's coal drop port has shifted, and the center distance of the coal feeder needs to be extended. However, due to the limitations of the installed equipment on site, the coal feeder cannot be extended arbitrarily. That is to say, the installed equipment is objectively formed as an obstacle, and the tech...
