Abstract
The utility model discloses a kind of kiln tail sealing device for cement rotary kiln, comprise smoke-box and kiln body, also comprise seal, described smoke-box tail end is welded with sealing ring, described kiln body is provided with dead turn, described seal comprises the large footpath section, the taper changeover portion that are coated at sealing ring and is coated at the path section of dead turn, and described large footpath section is threaded with sealing ring, and described path section and dead turn are slidably connected.This kiln tail sealing device for cement rotary kiln, realizes sealing by the slip of path section and dead turn, makes the ventilative reduction of kiln tail, ensure that sealing effectiveness, improve the service life of sealing device.
Description
Technical field
The utility model relates to a kind of kiln tail sealing device for cement rotary kiln.
Background technology
Cement rotary kiln is the capital equipment of clinker dry method and wet production line.Rotary kiln is widely used in the industry such as metallurgy, chemical industry, building refractory material, environmental protection.Inevitably there is gap at the kiln tail of cement rotary kiln, to be inhaled in kiln to stop extraneous air or in kiln, gas carries material and leaks, the kiln tail of cement rotary kiln must arrange sealing device.
Existing sealing device sealing effectiveness is poor, leaks out large.
Utility model content
In view of this, the purpose of this utility model is to provide that a kind of good seal performance, result of use are good, the kiln tail sealing device for cement rotary kiln of long service life.
The utility model is solved the problem by following technological means: a kind of kiln tail sealing device for cement rotary kiln, comprise smoke-box and kiln body, also comprise seal, described smoke-box tail end is welded with sealing ring, described kiln body is provided with dead turn, described seal comprises the large footpath section, the taper changeover portion that are coated at sealing ring and is coated at the path section of dead turn, and described large footpath section is threaded with sealing ring, and described path section and dead turn are slidably connected.
Further, described seal ecto-entad comprises pressing plate layer, intermediate layer and frictional layer successively.
Further, described frictional layer is made up of 60Si2Mn.
The beneficial effects of the utility model: kiln tail sealing device for cement rotary kiln of the present utility model, comprise smoke-box and kiln body, also comprise seal, described smoke-box tail end is welded with sealing ring, described kiln body is provided with dead turn, described seal comprises the large footpath section, the taper changeover portion that are coated at sealing ring and is coated at the path section of dead turn, and described large footpath section is threaded with sealing ring, and described path section and dead turn are slidably connected.This kiln tail sealing device for cement rotary kiln, realizes sealing by the slip of path section and dead turn, makes the ventilative reduction of kiln tail, ensure that sealing effectiveness, improve the service life of sealing device.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of seal.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in Figure 1-2: a kind of kiln tail sealing device for cement rotary kiln, comprise smoke-box 1 and kiln body 2, also comprise seal, described smoke-box tail end is welded with sealing ring 4, and described kiln body is provided with dead turn 5, and described seal comprises the large footpath section 31, the taper changeover portion 32 that are coated at sealing ring and is coated at the path section 33 of dead turn, described large footpath section is threaded with sealing ring, and described path section and dead turn are slidably connected.This kiln tail sealing device for cement rotary kiln, be no matter kiln body towards near the direction of smoke-box or the direction play away from smoke-box, all realize sealing by the slip of path section and dead turn, make the ventilative reduction of kiln tail, ensure that sealing effectiveness, improve the service life of sealing device.
As the further improvement of technique scheme, described seal ecto-entad comprises pressing plate layer 34, intermediate layer 35 and frictional layer 36 successively, and described frictional layer is made up of 60Si2Mn.Wherein intermediate layer is made up of high temperature resistant and composite that is good seal performance, pressing plate layer and frictional layer all through quenching heat treatment, thus have good elasticity and intensity, and frictional layer is made up of 60Si2Mn, anti-wear performance is good, further increases the service life of sealing device.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
