Description
Technical field:
The utility model relates to Novel kiln head sealing device, belongs to seal of rotary kiln technical field.
Background technology:
Rotary kiln is in running, under flap is sealed in the Action of Gravity Field of dust accumulation, gap is formed between bottom and cold wind shroud, a large amount of dusts is had to overflow, top is due to the effect of lineoutofservice signal pull, flap quick abrasion and losing efficacy, flap and cold wind shroud can not well be fitted, and cause kiln hood dust and sand large.Under hot operation state, cold wind shroud is easily out of shape.Because cold wind shroud slide plate snaps, is out of shape when flap is sealed in friction, and with irregular Abnormal Sound, component wear is serious.Steel wire rope is often deviate from from clip, due to high-temperature operation, brings very large difficulty to maintenance recovery.Cooling blower outlet is arranged in cold wind shroud bottom, cools kilneye cylindrical shell.Owing to being the outlet of one, single air channel, can only be confined to Local cooling, its cooling effectiveness is very poor.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide Novel kiln head sealing device.
The utility model kiln end sealing device, it is characterized in that it comprises seal closure, packaged air conditioner, labyrinth seal plate, cold wind shroud, air channel, air outlet, support, fixing seal plate and centrum flange and heat resisting steel flap, the outside of rotary kiln is provided with packaged air conditioner by seal closure, cold wind shroud is provided with between seal closure and packaged air conditioner, seal closure is rack-mount, packaged air conditioner is furnished with air outlet, one end of air outlet is communicated with air channel, the other end of air outlet is towards the horn mouth of cold wind shroud, the horn mouth outer setting of cold wind shroud has fixing seal plate, the inside of packaged air conditioner is provided with twice labyrinth seal plate, the outside in air channel is fixed with heat resisting steel flap by centrum flange.
As preferably, described twice labyrinth seal plate can adjusting play, and the gap between labyrinth seal plate and cold wind shroud is 20-50mm.
As preferably, described labyrinth seal plate and fixing seal plate form convection type labyrinth seal.
The beneficial effects of the utility model: it can overcome the drawback of prior art, scientific and reasonable for structure.Installation, mismachining tolerance affect little, do not have wearing terrain, good sealing effect, kilneye cylindrical shell good cooling results, extends the service life of cold wind shroud, and maintenance workload and accessory consumption decline to a great extent, effectively decrease and facing of rotary kiln main process equipment stop number of times, achieve certain economic benefit.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is plan structure schematic diagram of the present utility model.
1-seal closure; 2-packaged air conditioner; 3-labyrinth seal plate; 4-cold wind shroud; 5-air channel; 6-air outlet; 7-support; 8-fixing seal plate; 9-centrum flange; 10-heat resisting steel flap.
Detailed description of the invention:
As shown in Figure 1, this detailed description of the invention is by the following technical solutions: it comprises seal closure 1, packaged air conditioner 2, labyrinth seal plate 3, cold wind shroud 4, air channel 5, air outlet 6, support 7, fixing seal plate 8 and centrum flange 9 and heat resisting steel flap 10, the outside of rotary kiln a is provided with packaged air conditioner 2 by seal closure 1, cold wind shroud 4 is provided with between seal closure 1 and packaged air conditioner 2, seal closure 1 is arranged on support 7, packaged air conditioner 2 is furnished with air outlet 6, one end of air outlet 6 is communicated with air channel 5, the other end of air outlet 6 is towards the horn mouth of cold wind shroud 4, the horn mouth outer setting of cold wind shroud 4 has fixing seal plate 8, the inside of packaged air conditioner 2 is provided with twice labyrinth seal plate 3, the outside in air channel 5 is fixed with heat resisting steel flap 10 by centrum flange 9.
As preferably, described twice labyrinth seal plate 3 can adjusting play, and the gap between labyrinth seal plate 3 and cold wind shroud 4 is 20-50mm.
As preferably, described labyrinth seal plate 3 forms convection type labyrinth seal with fixing seal plate 8.
The operation principle of this detailed description of the invention is: cold wind blows into air channel 5 by blower fan and blowed to by blowing mouth in cold wind shroud 4 and prevents cylindrical shell temperature distortion from preventing the flue gas of kiln hood seal point and material to overflow due to the pressure of air to kiln hood cylindrical shell cooling (herein nearly 400 DEG C of temperature), air takes away hot-air at device Inner eycle laggard inlet/outlet pipeline to grate-cooler, kiln temperature is declined, circulation like this not only to kiln hood cooling but also prevent the flue gas of seal point and material excessive, thus reach one and perfectly seal cooling-down effect.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
