Abstract
The utility model discloses a bleaching device for the white cement clinker aggregate, which can solve the problem that the white cement clinker aggregate has no dedicated and effective bleaching devices presently. The bleaching device for the white cement clinker aggregate can improve the whiteness of the white cement. Compared with the pure watery blanching method, the whiteness can be improved by about 40% and the blanching time is shortened. Refractory bricks are arranged in a short and thick-shaped rotating cylinder body which is aslant arranged; both ends of the rotating cylinder body is fixed with end covers; a front end cover and a back end cover are respectively provided with an oil nozzle and an atomizing nozzle for the mixing water, etc., in this way, the bleaching device for the white cement clinker aggregate is formed.
Description
The utility model belongs to a kind of white cement clinker bleaching system.
It is mainly used in cement industry.
The key issue that general white cement is produced is the whiteness that how to improve white cement.The method of now continuing to use is trickle on white cement clinker.But bleaching effect is bad.Because this method mainly is to utilize trickle on the high temperature white cement clinker, vaporization decomposites a certain amount of active hydrogen atom, with the dark ferric iron atomic reaction that influences whiteness in the white cement clinker, thereby it is reduced into the ferrous iron atom of light color.In this reaction environment, the oxygen composition is heavier, and the active hydrogen atom of generation is less, and grog is nature and stacks, so the method bleaching effect of this simple trickle is a heterodyne.
The purpose of this utility model is to provide a kind of bleaching system of white cement clinker efficiently.The problem that it has overcome existing white cement factory white cement clinker bleaching effect difference has improved the white cement whiteness greatly.
Accompanying drawing is a white cement clinker bleaching system synoptic diagram.1 is the white cement clinker feed-pipe among the figure, 2 rotary barrels for the installation of tilting, and 3 is cylindrical shell support roller band, and 4 is the cylindrical shell gear band, and 5 is alkylate mixing water atomizing nozzle, and 6 is diesel oil or kerosene nozzle, and 7 is front end end cover, and 8 is rear end cap, and 9 is discharge nozzle.
Main points of the present utility model are, this device is a short and thick rotary barrel that tilts to install, the fixedly end cap that does not rotate with cylindrical shell is housed at the cylindrical shell two ends, this two end cap mainly seals, a gear band is arranged on the cylindrical shell, rotate by pinion(gear) and motor drives cylindrical shell, also have two support roller bands that play the role of positioning on the cylindrical shell, be lined with refractory materials in the cylindrical shell, the white cement feed-pipe is made with steel, and lining refractories, and diesel oil or kerosene nozzle are arranged in the feed-pipe lower end, in the cylinder back-end side of covering a mixing water atomizing nozzle that contains alkylate is arranged, also be connected to discharge nozzle on the rear end cap.
Just the white cement clinker of kiln discharge is entered in the rotary barrel by feed-pipe, and under the drive of the cylindrical shell rotation of tilting to install, white cement clinker constantly rolls and advances.At this moment, diesel oil or kerosene and the atomizing mixing water that is mixed with micro-alkylate by nozzle sprays under basic sealing and hot environment, produce dense reducing atmosphere in the bleaching system, and with the white cement clinker that constantly stirs in the ferric iron atomic reaction, generate the ferrous iron atom of light color:
Fe
2O
3＋（H
2＋2CO）＋O
2＝2FeO＋H
2O＋2CO
2
Thereby white cement clinker is bleached rapidly.
The utility model is used for existing white cement factory, can improve the white cement whiteness significantly, improves whiteness about 40% than the method for general simple trickle bleaching, and has shortened the bleaching time of white cement, faster production cycle.
Among the embodiment of the present utility model, the cylindrical shell specification of short-thick type is φ 1300 * 1400mm, and feed-pipe is φ 300mm, and discharge nozzle is φ 250mm, and inner lining refractory block is installed between cement kiln end and the clinker warehouse.Generally after this poaching engine bleaching, whiteness can be brought up to 85～90 degree.
Claims (3)
1, a kind of white cement clinker bleaching system is characterized in that two ends are equipped with the short and thick rotary barrel of end cap and are furnished with a plurality of nozzles.
2, device according to claim 1 is characterized in that tilting being lined with refractory materials in the rotary barrel of installation.
3,, it is characterized in that the rear and front end covers the mixing water atomizing nozzle that diesel oil or kerosene nozzle is housed respectively and contains alkylate according to claim 1,2 described devices.
