Abstract
The utility model relates to an unloading device for mechanical vertical kilns. The utility model is characterized in that the vertical pressure distribution on the surface of an unloading grate is changed, the technical measures of high position ventilation and atomizing cool are adopted, so, the quality of cement grog is improved.
Description
The utility model is a kind of machine shaft kiln that is used for manufacture of cement, and it relates to tower machine shaft kiln, coils improvement and raising on tower machine shaft kiln discharging bamboo comb structural design and the performance, belongs to the cement machinery field.
At present, the machine shaft kiln has obtained using widely with its distinctive advantage in China's cement industry, and considerable status is arranged.Mechanical shaft kiln burning is because due to the heat exchange pattern, cause central ventilation poor, fire in a stove before fuel is added injustice, the degree of calcination of grog that makes machine shaft kiln centre wants not enough compared with limit portion, there are differences qualitatively, particularly the control of the content of free calcium oxide is unstable, and because discharging bamboo comb pressure at right angle centre, surface and limit portion gap are little, this has just influenced the quality of grog behind the kiln discharge.In addition, because the machine shaft kiln generally adopts discharging bamboo comb leg space ventilation, this has just caused flowing resistance big, makes in the grog cooling after calcine on discharging bamboo comb top to be affected, and can not stop β-C fully effectively
2S is converted into r-C
2S has also directly had influence on the quality of clinker.
The purpose of this utility model is to design at the structural deficiency of the said equipment provides a kind of novel shaft kiln discharging device, by structural improvement makes the quality of kiln discharge grog obtain improving significantly to the discharging bamboo comb.
The purpose of this utility model reaches by following measure, discharging bamboo comb after the improvement comprises ventilation duct, water pipe and water ring, it is characterized in that, discharging bamboo comb top to the height distance a of bottom be the 1000-2000mm ventilation duct from the discharging bamboo comb one through to its tip position, position height is that a perforate is arranged on 700-1700mm and the top, is set with water pipe in the ventilation duct, and the water pipe top is stretched out on the top of ventilation duct and its and adorned a water ring and connect one with ventilation duct.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of the utility model device
Fig. 2 is the schematic diagram of water ring in the utility model device.
Wherein Fig. 2 a is an annular, and Fig. 2 b is taper, and Fig. 2 c is a T shape, and Fig. 2 d is a clavate.
Below with reference to drawings and Examples the utility model is further described.
Referring to shown in Figure 1, shaft kiln (6) is tower or coils tower shaft kiln that directly through being 1700-3200mm, charging aperture (7) is about 8000-12000mm to the height distance of discharging bamboo comb (3) for it.Discharging bamboo comb (3) after the improvement comprises ventilation duct (2), water pipe (4) and water ring (1), and discharging bamboo comb (3) top is 1000-2000mm to the height distance (a) of bottom.Adopting this structural design is to distribute for the surperficial pressure at right angle that changes discharging bamboo comb (3), make the edge bigger than the pressure in centre, like this, the amount of edge discharging is just many, the distribution of the trend of discharging is more reasonable again after making clinker burning more complete, because the edge is more abundant than the centre calcining.In addition, make ventilation duct (2) from discharging bamboo comb (3) one through to its apical position, position height is 700-1700mm, one perforate (5) is arranged on the top of discharging bamboo comb (3), be set with water pipe (4) in the ventilation duct (2), water pipe (4) top is stretched out on the top of ventilation duct (2) and its and is adorned a taper water ring (1) and connect one with ventilation duct (2).Owing to adopted high-order direct air blast to reduce resistance, improved the shortcoming of central ventilation difference greatly, the fire in a stove before fuel is added is even, and clinker burning is complete.In addition, make discharging bamboo comb (3) top in air blast, spray atomized water steam owing to loaded onto water pipe (4) and water ring (1) by water ring (1), so just greatly improve the cooling velocity of discharging bamboo comb (3) top grog, stoped β-C effectively
2S is converted into r-C
2S, the while has also removed in the grog effectively and has contained hazardous substance-free calcium oxide (fcao), and cement stability is improved greatly.In a word, by having improved the structure of discharging bamboo comb (3), and adopted the design of high-order ventilation atomizing cooling, improved the quality of clinker greatly, guarantee is provided for the various parameters of cement are up to standard from several respects.
In addition, shown in accompanying drawing 2, water ring (1) be shaped as a kind of in annular, taper, T shape and the straight clavate.
The utility model compared with prior art has lot of advantages, has changed discharging bamboo comb Surface Vertical pressure distribution, makes the edge bigger than the pressure in centre, grog is calcined fully after again the trend of discharging distribute more reasonable; The high-order ventilation also makes clinker burning more complete, and the atomizing cooling has not only guaranteed clinker quality but also controlled the content of free calcium oxide (Fcao), and product quality is guaranteed all sidedly.
Claims (2)
1, a kind of machine shaft kiln discharging device that is used for, it comprises discharging bamboo comb, ventilation duct, water pipe and water ring, it is characterized in that:
Discharging bamboo comb top is 1000-2000mm to the height distance a of bottom;
One through to its tip position, position height is that a perforate is arranged on 700-1700mm and the top to ventilation duct, is set with water pipe in the ventilation duct from the discharging bamboo comb, and the water pipe top is stretched out on the top of ventilation duct and its and adorned a water ring and connect one with ventilation duct.
2, device for discharging according to claim 1 is characterized in that: water ring be shaped as a kind of in annular, taper, T shape and the straight clavate.
