Abstract
The utility model relates to the technical field of sealing of rotary kilns, and particularly discloses a novel sealing device for a rotary kiln. According to the sealing device of the rotary kiln, the inner wall of an end portion, where a kiln head or a kiln tail cover and a rotary kiln barrel body are fastened, of the kiln head or the kiln tail cover are fixedly provided with a steel plate C and a steel plate A in sequence, felted wool A and felted wool B are respectively fixed at two sides of the steel plate A arranged on the inner side of the kiln head or the kiln tail cover, and rubber and felted wool E are respectively fixed at the left side and the right side of the steel plate C. A steel plate B is fixedly arranged on the rotary kiln barrel body and positioned between the steel plate C and the steel plate A, and two sides of the steel plate B are fixedly provided with felted wool C and felted wool D. A labyrinth structure is formed by the steel plates arranged in the sealing device of the rotary kiln, felted wool adopting a soft structure is fixed on the steel plates so as to fix the kiln head or the kiln tail cover to be closely contacted with the sealing device, so that gaps caused by deformation of a kiln body is effectively avoided; meanwhile, price of felted wool is cheap, disassembly and assembly are convenient, overhauling is convenient, and economy is good.
Description
Technical field
The utility model belongs to the seal of rotary kiln technical field, is specifically related to a kind of novel rotary kiln sealing device.
Background technology
Rotary kiln is required capital equipment in the metallurgy industries such as chemical industry, cement and aluminium oxide, generally works under negative pressure.Between the shell portion of rotary kiln and fixing jockey, between kiln head cover, kiln hood, there is inevitably the slit, leaks from kiln head cover, kiln hood in order to stop in the extraneous air intake kiln and to prevent that gas carries material in the kiln, on the rotary kiln sealing device must be set.
The seal of rotary kiln device is the fixing kiln head cover in cylindrical shell and the two ends of rotary kiln, the device that the kiln hood is connected, makes joint gap under the positive and negative pressure operation, does not leak out in the kiln, does not attack in retaliation, to the basic demand of seal of rotary kiln device is: good seal performance, reliably.But sealing device commonly used all can not guarantee sealing at present.Radial seal, if adopt cast iron materials to make friction sealed plate, such sealing plate and cylindrical shell friction are large, sealing plate is changed too frequent; If adopt graphite or carbon materials to make friction plate, though increase service life, cost is higher; The axial contact sealing, loose collar is pressed on the retainer ring by spring, and is that pine is enclosed within on the kiln body, so that the kiln body moves freely and swings.Because the result of pine cover has produced the place of leaking out.The fish scale lamellar seal: sealing effectiveness is not good, and service life is short, leaks out easily in the kiln operating process, increases power consumption.
Summary of the invention
The purpose of this utility model is to provide a kind of novel rotary kiln sealing device, can solve the problem that rotary kiln leaks out, attacks in retaliation.
The technical solution of the utility model is as follows: a kind of novel rotary kiln sealing device, on kiln hood that kiln hood/kiln hood and cylinder of rotary kiln are interlocked/kiln hood inner wall of end, be installed with successively respectively steel plate C and steel plate A, wool felt A and wool felt B are separately fixed at the both sides of the inboard steel plate A of kiln hood/kiln hood, and rubber and wool felt E are separately fixed at the left and right sides of steel plate C; Be installed with steel plate B at cylinder of rotary kiln, be located between steel plate C and the steel plate A, and be installed with wool felt C and wool felt D in steel plate B both sides.
Described steel plate C and steel plate A guarantee in operation process that apart from the cylinder of rotary kiln certain distance steel plate C and steel plate A and cylinder of rotary kiln do not rub.
Described steel plate B guarantees in operation process that apart from kiln hood/kiln hood certain distance steel plate B and kiln hood/kiln hood does not rub.
Described wool felt A, wool felt B, wool felt E and rubber and cylinder of rotary kiln close contact; Described wool felt D and wool felt C and kiln hood/kiln hood close contact.
Described wool felt D is when initial cold conditions is installed and wool felt E close contact; Make progress when the being rotary kiln running summation of vibration and expansion of the distance of described wool felt C and wool felt B.
Remarkable result of the present utility model is: the steel plate that a kind of novel rotary kiln sealing device described in the utility model is installed forms labyrinth structure, adopt the wool felt of flexible structure to be fixed on the steel plate, it is tightr that kiln hood/kiln hood is contacted with the sealing device, can effectively overcome the slit that the kiln body deformability produces; Simultaneously, wool felt low price, easy accessibility, easy access, and good economy performance.
