Efficient and energy-saving coal gangue brick firing system

Abstract

The invention discloses an efficient and energy-saving coal gangue brick firing system. The efficient and energy-saving coal gangue brick firing system comprises a heating furnace, a firing furnace, aslag discharging pipe, a through pipe and a chimney, wherein the firing furnace is arranged on the surface of the top of the heating furnace; the bottom of an inner cavity of the firing furnace is communicated and connected with the top of the inner cavity of the heating furnace through the through pipe; the slag discharging pipe is mounted at the bottom of the firing furnace; the chimney is inserted into the surface of the top of the firing furnace; a first fixed plate is mounted on the surface of one side wall of the heating furnace; a driving mechanism is mounted on the surface of the first fixed plate; a rotary shaft is mounted in the inner cavity of the firing furnace; a second bearing is mounted at one end of the rotary shaft; and the bottom of the second bearing is connected with the firing furnace through a stand column. According to the efficient and energy-saving coal gangue brick firing system disclosed by the invention, the driving mechanism can be used for driving a rotary mechanism to rotate through the rotary shaft, so that coal gangue bricks on a bearing mechanism can be uniformly fired; a draught fan and a spraying nozzle are mutually matched so that the firing speed of the coal gangue bricks can also be improved; meanwhile, a temperature sensor and a touch all-in-one machine can also be used for monitoring the temperature in the firing furnace.

Description

technical field [0001] The invention relates to the technical field of coal gangue brick production equipment, in particular to a high-efficiency and energy-saving coal gangue brick firing system. Background technique [0002] The main component of coal gangue bricks is coal gangue. Coal gangue is solid waste discharged during the coal mining process and coal washing process. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium, cobalt). [0003] The production cost of coal gangue bricks is lower than that of ordinary clay bricks. Using coal gangue to make bricks not only saves land, but also consumes mine waste. It is a low-carbon building material that is conducive to environmental protection. . [0004] But, there is following shortcoming in existing coal gangue brick firing system: [0005] 1. Most of the existing coal gangue brick firing systems use ...
