Description
Technical field
The utility model belongs to plant equipment manufacturing technology field, is specifically related to a kind of modification device of the hot-air heating type for the coal dust modification.
Background technology
At present, for the mill coal modification and prepare modified coal coking, not only need coal dust is mixed, and need to heat coal dust, in uniform temperature, carry out after the match effective modification, the modification temperature peak demand reaches 450 ℃.Current most mixing equipment does not possess heating function, only a few heating mixing equipment, a kind of Double cone spray dosing drying blendor as disclosed as Chinese patent literature CN2562150Y, comprise tank body, frame, the tank skin of described tank body is provided with for the chuck by heat medium, by after chuck, can carry out heat drying when heat medium to the material in tank.This utility model has heating function, but heating-up temperature is low, can not meet the temperature requirement that the coal dust modification need to reach.And the drying blendor of Chinese patent literature CN2542431Y bulletin, mode of heating is heated by importing hot blast, and heating-up temperature is far below 450 ℃, and is only applicable to the material that granularity is larger, the coal dust that is less than 3mm for granularity easily blows out with hot blast, aggravating working environment.
Therefore, need a kind of modification device that is applicable to the coal dust modification of invention badly, to meet variation, high-temperature, multi-functional mixed and modified requirement.
The utility model content
For making up the deficiency of existing equipment, the utility model provides a kind of air-heating type coal dust modification device, and it can fully mix coal dust modifier with the mill coal powder, can provide again the modification of mill coal powder required uniform temperature field.
The purpose of this utility model is achieved by the following technical solution: a kind of air-heating type coal dust modification device, comprise motor, cylindrical shell and system control device, described motor is arranged on the cylindrical shell top, described cylindrical shell is cylindrical, the cylindrical shell top is provided with blast pipe and charge door, and inside is provided with shaft, and outer wall is provided with for passing into the warm-air pipe of hot blast, bottom is conical design and is provided with discharging opening, and described system control device is controlled motor speed, hot blast temperature, modification time.
Further, the position that is connected with shaft with bottom, described cylindrical shell top disposes water-cooling bearing block, shaft excess Temperature while preventing from heating and damage motor and bearing.
Further, described blast pipe is for steam and decomposition gas in expelling tube.
Further, be provided with spirality stirrer paddle and soaking scraper plate on described shaft; Described soaking scraper plate is pressed close to the cylinder inboard wall setting; The blade rotated during stirring rises coal powder spiral, and then forms the circular flow mutually mixed from bottom to top in cylinder; The soaking scraper plate rotates with shaft in addition, has increased relative motion and the blending of coal dust, and in time near hot coal powder cylinder inboard wall is upgraded, thereby can rapid mixing, heating and modification coal dust.
Further, described warm-air pipe is semicircle ring-type structure, is looped around around cylinder body outer wall, and described warm-air pipe periphery arranges the one layer of heat preservation layer; Hot blast imports from warm-air pipe air inlet one side, and around deriving from air outlet after barrel, hot blast transfers heat to barrel, and then, by the heating of the coal dust in cylinder, has avoided hot blast directly to pass in cylinder coal dust is blown out; Described hot blast can derive from the burning gases of steel and iron industry high temperature hot waste gas or coke-stove gas or blast furnace gas or coal gas of converter, hot blast temperature is high and supply is stable, control cold/hot blast ratio by system control device, can meet the modification requirement of coal dust in 25～450 ℃ of scopes.
Further, three thermocouples that are mutually 120 ° of horizontal sextant angles are installed on described cylinder body bottom inwall, temperature detection accurately, reliably; Described cylinder body bottom is designed to taper shape, is beneficial to go out fast the clean coal powder.
Than existing equipment, the utility model is simple in structure, mixing efficiency is high, Hybrid Heating is even, applicability to the particulate coal dust is good, not only can mix for the normal temperature of coal dust, can also be for the coal dust different temperatures heat modification after the match, evenly, fully, modification temperature reaches as high as 450 ℃ in modification.In addition, the utility model is used industrial hot waste gas heating, and energy effective recycling hot waste gas heat energy, save the energy and resource.
