Description
Technical field
The utility model belongs to plant equipment manufacturing technology field, is specifically related to a kind of electrothermal coal dust modification device.
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 500 ℃.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.Although this utility model has heating function, heating-up temperature is low.And the drying blendor of Chinese patent literature CN2542431Y bulletin, mode of heating is heated by importing hot blast, its main purpose is dried material in batch mixing, the temperature range of general dried material is at 85 ℃-180 ℃, well below 500 ℃ of the desired temperature of coal dust modification, and be only applicable to the material that granularity is larger, for granularity, at the coal dust of 0.5-3mm, not only easily stop up shaft, and easily with hot blast, blow out aggravating working environment.
Therefore, needing invention badly a kind ofly can meet various grade coal dusts, possess the coal dust modification device that temperature is high, material reaction is abundant, modified effect is good.
The utility model content
For making up the deficiency of existing equipment, the utility model provides a kind of electrothermal 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 temperature field.
The purpose of this utility model is achieved by the following technical solution: a kind of electrothermal coal dust modification device, comprise motor, system control device and cylindrical shell, described motor is arranged on the top of cylindrical shell, described cylindrical shell is cylindrical, the cylindrical shell top is provided with blast pipe and charge door, inside is provided with shaft, and outer wall is around the heating wire that heating use is arranged, and bottom is conical design and is provided with discharging opening.Described system control device is controlled startup and the termination of motor speed, heating-up temperature, reaction time, system.
Further, the position that is connected with shaft with bottom, described cylindrical shell top disposes water-cooling bearing block, shaft axle 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 propeller blade 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 heating wire is embedded in the cylinder body outer wall interlayer, and the skin of heating wire arranges heat-insulation layer, prevents heat radiation.The heating wire heating power, can meet the modification requirement of coal dust in 25～500 ℃ of scopes.
Further, described cylinder inboard wall upper, middle and lower segment position is equipped with thermocouple; 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, and mixing efficiency is high, and has heating function, and temperature can reach 500 ℃.
