Apparatus for manufacturing coal briquette

Abstract

Provided is an apparatus for manufacturing a coal briquette comprising: a mixer for manufacturing a mixture by mixing powdered coal and a binder so as to more surely pulverize lump coals and minimize adhering coals when pulverizing the coals; a gravity feeder, connected to the lower end of the mixer, for supplying the mixture; a molder, connected to the lower end of the gravity feeder, for molding the mixture supplied from the gravity feeder; and a pulverizer, installed at the top end of the gravity feeder, for pulverizing the mixture introduced into the gravity feeder, wherein the pulverizer comprises a rotor, which is rotatably installed inside a housing and at a distance away in the axial direction from which a pulverizing plate is installed, a driving portion for rotating the rotor, and a scraper member, installed inside the housing and arranged on the front surface of the pulverizing plate, for scraping off the mixture adhered to the pulverizing plate.

Description

technical field [0001] The invention relates to a briquette manufacturing device. More specifically, the present invention relates to a briquette manufacturing device capable of minimizing coal sticking when crushing lump coal. Background technique [0002] In the smelting reduction ironmaking method, a reduction furnace for reducing iron ore and a smelting gasifier for melting the reduced iron ore are used. When iron ore is smelted in the smelting gasifier, coal briquettes are loaded into the smelting gasifier as a heat source for smelting iron ore. Reduced iron is smelted into molten iron and slag in the smelting and gasifier, and then discharged to the outside. The briquettes charged into the smelter-gasifier form a packed bed of coal. Oxygen is blown in through the tuyeres provided on the smelting and gasification furnace to burn the coal packed bed to generate combustion gas. Combustion gases rise through the coal-packed bed and are transformed into high-temperature...

AI Technical Summary

Problems solved by technology

[0005] However, in the conventional coal crushing process, coal mixed with water and viscous molasses frequently adhered to the crushing plate, etc.

Therefore, the crushing device cannot crush the lump coal smoothly, resulting in a reduction in the quality of the coal briquettes. If the adhesion of the coal material is serious, the operation needs to be suspended, thereby reducing productivity.
