The utility model is described in further details combined with specific embodiments below:
The utility model discloses a kind of rotary kiln end sealing devices, and the kiln hood position of the rotary kiln of production cement is arranged in
It sets, sealing effect is good, can reduce burnup, while kiln cylinder body can be effectively protected, and structure is simple, and here is specifically to implement
Example:
A kind of rotary kiln end sealing device, including cold wind shroud 2 and setting are deposited between 2 outside of cold wind shroud and cold wind shroud 2
Cylindric seal closure 3 in gap, it is specific as shown in Figure 1.
The cold wind shroud 2 and kilneye cap iron 10 of the utility model constitute the toroidal cavity for surrounding kiln hood, and cold wind shroud 2 includes one
Molding body section 2-1 and wind inlet section 2-2, wherein the diameter of wind inlet section 2-2 is greater than the diameter of body section 2-1, keeps cold wind shroud 2 last
It holds the area of air inlet to expand, facilitates being blown into for cold wind.The outside of body section 2-1 and wind inlet section the 2-2 intersection of cold wind shroud 2 is solid
Second sealing plate 5 is set surely, and there are gaps between the edge and seal closure 3 of the second sealing plate 5.Cold wind shroud 2 is solid by connection frame
Be scheduled on the kiln cylinder body 1 on the outside of kiln hood, connection frame can use adjustable in length bolt, guarantee cold wind shroud 2 to kiln cylinder body 1 it
Between distance be consistent, hair dryer is arranged in the end air inlet of cold wind shroud 2.The blowing mouth of hair dryer is tilted towards kiln cylinder body
Setting, enables cold wind to blow to the lateral wall of kiln cylinder body 1 and move along the lateral wall of kiln cylinder body 1.Indicated by arrow in Fig. 1
It is exactly the direction of motion of cold wind.
The seal closure 3 of the utility model is arranged outside cold wind shroud 2, and the lower end of seal closure 3 is fixed by the bracket in rotary kiln
On the platform of supported underneath rotary kiln.It is close that the first sealing plate 4, third sealing plate 6 and the 4th is successively fixedly installed in 3 inside of seal closure
Sealing plate 7, the first sealing plate 4 are located at the outside of 2 body section 2-1 of cold wind shroud, and third sealing plate 6 is located at the outside of wind inlet section 2-2, the
Four sealing plates 7 are located at the end of seal closure 3；The first sealing plate 4, the second sealing plate 5, the third sealing plate the 6, the 4th set gradually
Sealing plate 7 forms labyrinth structure, and there are gaps between the first sealing plate 4 and third sealing plate 6 and cold wind shroud 2.4th sealing plate 7
For graphite block, the end of the 4th sealing plate 7 and 2 terminal outboard surface gluing, sealing of cold wind shroud, the cold wind whole for blowing out hair dryer
Into in cold wind shroud 2, avoids small part cold wind and enter the efficiency of combustion in seal closure 3 and influencing kiln hood, effectively improve clinker
Quality and yield, while avoiding 3 end of seal closure and directly being contacted with kiln cylinder body 1, prevent rotary kiln continuous during rotation
It rubbing with 3 end of seal closure and disconnected kiln accident occurs, the 4th sealing plate 7 is graphite block, in rotary kiln operation process, cold wind shroud
2 are bonded friction with graphite block, can increase the lubricity of rubbing surface, avoid the damage to rub to cold wind shroud 2.First sealing plate 4
Gap between cold wind shroud 2 is 5~10mm, and the gap between the second sealing plate 5 and seal closure 3 is 8~15mm, third sealing
Gap between plate 6 and cold wind shroud 2 is 12~18mm.Four sealing plates form mazy sealed passage in seal closure 3, drop
The kinetic energy of the low sandstone leaked avoids outlet particles effect environmental sanitation once in a while, sandstone is finally made to drop to seal closure 3
Bottom, into back hopper.
3 lower end of seal closure of first sealing plate, the 4 kilneye side of the utility model is connected to the first back hopper 8, the first sealing
3 lower end of seal closure between plate 4 and the second sealing plate 5 is connected to the second back hopper 9.First back hopper 8 and the second back hopper 9
For ladder hierarchical structure, mountable double plate weighted valves lock wind blanking among the first back hopper 8 and the second back hopper 9, convenient

The working principle of the utility model are as follows: when thering is sandstone to leak in the gap of kilneye, the sandstone that leaks
Into in the labyrinth passage between seal closure 3 and cold wind shroud 2, the sandstone kinetic energy leaked is very high, when by the first sealing
After the blocking of plate 4, most of sandstone falls on the bottom of seal closure 3 and enters in the first back hopper 8, and small part sandstone is close from first
Pass through in gap between sealing plate 4 and cold wind shroud 2, after the blocking by the second sealing plate 5, fall on 3 bottom of seal closure, into
Two back hoppers 9, finally only few sandstone can be by the gap between the second sealing and seal closure 3, even if passing through, by the
The blocking of three sealing plates 6, also falls into the bottom of seal closure 3, therefore, can reach the 4th sealing plate 7 almost without sandstone, reach
Good sealing effect.The structure of cold wind shroud 2, the cold wind for being blown into hair dryer fully enter in cold wind shroud 2, avoid part
Cold wind enters in seal closure 3, has an impact to the sealing effect of seal closure 3, while cold wind being avoided to influence the burning of kilneye, reduces
Coal consumption improves the quality of clinker.Seal closure 3 avoids the 4th sealing plate 7 directly by graphite block and 2 gluing, sealing of cold wind shroud
Contact friction with kiln cylinder body 1, effective protection kiln cylinder body 1 prevents disconnected kiln accident.
The good seal performance of the rotary kiln end sealing device of the utility model avoids part sandstone because in sealing device
Air pressure is high and the case where the polluting environment that leak outside, while avoid makes kiln cylinder body exist because sealing device directly contacts kiln cylinder body
Disconnected kiln accident occurs in the case where long-term friction, effectively protects kiln cylinder body, security performance improves, and on the other hand also drops significantly
Low energy consumption, improves the service performance of rotary kiln, economizes on resources, reduces production cost, the rotary kiln end sealing device, structure
Simply, it easily improves.
