Description
Technical field
The utility model relates to a kind of rotary kiln tail sealing device, the sealing device with good seal performance that specifically a kind of many structures are formed.
Background technology
At present, rotary kiln is one of equipment comparatively main in cement plant, alumina producer and other metallurgical industry.Most dangerous waste incinerations is handled and is also adopted rotary kiln incineration.Rotary kiln divides several parts such as kiln hood, body, kiln tail, transmission mechanism.Wherein body is rotated motion, and kiln hood and kiln tail are fixed position, and the kiln tail is fixed in the dual firing chamber.Because rotary kiln is kept in motion, inside is again hot environment, and general temperature can reach 1100 ℃.Therefore, the sealing of rotary kiln has very important significance for the normal operation and the efficiency operation of entire equipment.The sealing device of rotary kiln needs well good sealing effectiveness, and the appearance of anti-leak-stopping material situation reduces the inleakage of junction simultaneously again as far as possible.
Therefore just have high requirements on rotary kiln body and the type of attachment that is fixed on the kiln tail that dual firing chamber is connected.The prior art major part is to use graphite grazing separately, though guaranteed the tightness of sealing, can't overcome for the high temperature of kiln tail metal shell, therefore can only be controlled ignition temperature, can not realize 1100 high temperature incinerations of spending in the rotary kiln.Have influence on the output and the quality of rotary kiln.
Also have the part sealing to adopt soft conjunctive tissue sealing, but soft tissue and the direct sealing of kiln tail are called a new problem again, and soft conjunctive tissue often can't be born the high temperature of rotary kiln.
To sum up, be badly in need of at present a kind of can be under hot environment, play between rotary kiln body and the dual firing chamber the effectively sealing device of sealing of kiln afterbody.
The utility model content
In order to improve and remedy the defective of prior art, the purpose of this utility model is to provide a kind of can play the sealing device that the kiln afterbody effectively seals between rotary kiln body and the dual firing chamber under hot environment.
In order to realize the purpose of this utility model, the utility model adopts following technical scheme:
A kind of rotary kiln tail sealing device, the sealing device comprises that fixed cover is located at the arc graphite grazing piece sealing on the kiln tail, the circular sealing block that the circular arc sealing block overlap joint that described arc graphite grazing piece is a plurality of 20 five equilibriums forms, arc graphite grazing piece is provided with groove, steel wire rope is pressed in the groove of graphite grazing piece, and, guarantee constant contact pressure by the weight haulage cable.
Above-mentioned a kind of rotary kiln tail sealing device, wherein, the lap joint of described circular arc sealing block is " Z " type joint.
Above-mentioned a kind of rotary kiln tail sealing device, wherein, described weight haulage gear quantity is one or two.
Above-mentioned a kind of rotary kiln tail sealing device, wherein, described sealing device also comprises a labyrinth type air intake hermetically-sealed construction, and this labyrinth type air intake hermetically-sealed construction is arranged at the kiln tail end, this labyrinth type air intake structure is formed by polylith sealing protection plate overlap joint, between each sealing protection plate the fixed interval (FI) is arranged.
Above-mentioned a kind of rotary kiln tail sealing device, wherein, described sealing protection plate is a nichrome steel sheet material matter.
Above-mentioned a kind of rotary kiln tail sealing device wherein, also comprises an air cooling equipment, and this air cooling equipment is located on the kiln tail, and this air cooling equipment is provided with air blast and a plurality of ventilation duct, the corresponding setting with labyrinth seal structure of described ventilation duct.
Advantage of the present utility model and benefit:
The utility model sealing device is in the key position that connects between rotary kiln and the dual firing chamber, promptly dynamic and static binding site.Contact sealing in order to guarantee that the rotary kiln surface of revolution and dual firing chamber equipment connecting portion remain, prevent that cold wind from entering.Adopt steel wire rope and weight to compress the combining form of graphite grazing piece, guarantee that constant contact pressure further plays the effect of good fit sealing.The graphite grazing piece is formed by the circular arc sealing block overlap joint of a plurality of 20 five equilibriums, and this kind design has effectively prevented graphite grazing piece cracked situation in kiln body motion process.Because the existing high-temperature flue gas corrosion of rotary kiln working environment has slag erosion again, therefore requires sealing protection sheet material matter high temperature resistant, corrosion-resistant, wear-resistant, so select high nickel chromium triangle heat resisting cast steel for use.Be protection kiln body steel plate; the utility model has increased kiln tail air cooling equipment, and therefore further cooling will guarantee to feed a certain amount of cooling air cooling on structural design; therefore adopt bonding relation between the sealing protection plate, the joint form between its each plate forms mazy hermetically-sealed construction.
Above the utility model content part has been done sufficient explanation to the utility model, below in conjunction with the drawings and specific embodiments the utility model is described in further details, present embodiment only is the utility model preferred forms, is not to qualification of the present utility model.
