An integrated coal feeder for pulverized coal grinding and drying

Abstract

The invention discloses a pulverized coal grinding and drying integrated coal feeder, which comprises a coal grinding machine body, and a coal grinding device is arranged in the coal grinding machine body, and the coal grinding device includes upper and lower end faces respectively arranged on the coal grinding machine body The upper coal grinding cavity and the lower coal grinding cavity in the upper coal grinding cavity are provided with a through cavity that penetrates the upper coal grinding cavity and the lower coal grinding cavity to penetrate it up and down, and the left and right of the upper coal grinding cavity correspond to There is a crushing wheel that can crush large coal lumps, and the left and right sides of the lower coal grinding chamber are correspondingly equipped with grinding wheels that can grind small coal lumps. The present invention crushes coal lumps into coal powder by setting it in the coal grinding device. The drying device can dry coal powder, which is conducive to the full combustion of coal, saving resources and reducing carbon dioxide emissions.

Description

technical field [0001] The invention relates to the technical field of fuel supply devices for combustion equipment, in particular to a coal feeder integrated with pulverized coal grinding and drying. Background technique [0002] With the rapid development of economy and technology, people pay more and more attention to the problem of resource utilization and the health of front-line workers. After coal is burned quickly, too much unburned slag will be produced, which will cause environmental pollution and waste of resources. , Insufficiently burned coal will also increase carbon dioxide emissions. The existing coal delivery device cannot integrate coal pulverization and drying well, and the existing coal delivery device requires too much manual labor to participate in the operation. Not only is it inconvenient to operate, but the work efficiency is low, and the coal dust produced by the work will also have a serious impact on people's health. Contents of the invention ...
