Abstract
The utility model discloses a kiln head sealing structure for a rotary kiln, which adopts a mode of radial contact-type seal formed by tightly compressing an elastic sheet by a steel wire rope. The kiln head sealing structure mainly comprises kiln opening back iron on a kiln body, a kiln head cover, a sealing sheet seat, a sealing sheet and a spring, wherein an annular groove used for installing a cold air sleeve is formed in the kiln opening back iron, and a shifting block mechanism is arranged on the cold air sleeve; the cold air sleeve is a component with a thickened periphery, an annular groove is formed in the periphery of the cold air sleeve, and the annular groove is inlaid with the annular groove of the kiln opening back iron, so that double seal is formed at the contacted part between the kiln opening back iron and the cold air sleeve. Because the double seal is adopted between the cold air sleeve and the kiln opening back iron, the sealing effect of a kiln head is enhanced; a phenomenon of ash jet is avoided even if a gap is too large, and due to the large gap, installation construction and maintenance can be contributed.
Description
Technical field
The utility model relates to the rotary kiln of cement production enterprise.
Background technology
At present, the rotary kiln end hermetically-sealed construction of cement production enterprise has many forms, and the technology relevant with this Shen is that steel wire rope compresses flexure strip radial contact, as shown in Figure 1.Its structure is mainly on kiln body 6, to be bolted a circle kilneye cap iron 7 and kiln head cover 1, sealing bar 2, diaphragm seal 3 and spring 4 are installed, and kilneye cap iron 7 is provided with cold wind shroud 8, and cold wind shroud 8 is provided with shifting block mechanism 5.In rotary kiln when running, drives cold wind shroud to rotate by shifting block machine structure, relative static between cold wind shroud 8 and kilneye cap iron 7.Wherein, kilneye cap iron is provided with annular groove, and cold wind shroud periphery is embedded in annular groove, forms and is similar to mazy seal form.The deficiency of this seal form is, inconvenience while installing when gap is too small between cold wind shroud and kilneye cap iron, and when excessive, sealing effectiveness is bad, and during operation often there is emitting grey phenomenon in kiln hood.So must improve rotary kiln end hermetically-sealed construction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and rotary kiln end hermetically-sealed construction is improved, and designs a kind of novel rotary kiln end hermetically-sealed construction.
A rotary kiln end hermetically-sealed construction, it adopts steel wire rope to compress flexure strip radial contact seal form; Mainly comprise kilneye cap iron, kiln head cover, sealing bar, diaphragm seal and spring on kiln body, kilneye cap iron is provided with for the annular groove of cold wind shroud is installed, and cold wind shroud is provided with shifting block mechanism; It is characterized in that, described cold wind shroud is the parts of a periphery thickening, and periphery is provided with annular groove, together with this annular groove is embedded in the annular groove of kilneye cap iron, makes kilneye cap iron and cold wind shroud contact position form two seals.
The utility model has the advantages that: owing to adopting two seals between cold wind shroud and kilneye cap iron, strengthened kiln hood sealing effectiveness, even if excesssive gap also there will not be the grey phenomenon of spray, gap is large can be conducive to installation and maintenance.
Accompanying drawing explanation
Fig. 1 is the sealed structure chart of existing rotary kiln end;
Fig. 2 is sealed structure chart of the present utility model.
Marginal data, 1-kiln head cover; 2-seals bar; 3-diaphragm seal; 4-spring; 5-shifting block mechanism; 6-kiln body; 7-kilneye cap iron; 8-cold wind shroud.
The specific embodiment
Fig. 1 is the sealed structure chart of existing rotary kiln end, and its structure is on the books in background technology, is not described in detail in this.
Fig. 2 is sealed structure chart of the present utility model, as can be seen from the figure: its structure is to adopt steel wire rope to compress flexure strip radial contact seal form; Mainly comprise kilneye cap iron 7, kiln head cover 1, sealing bar 2, diaphragm seal 3 and spring 4 on kiln body 6, kilneye cap iron 7 is provided with for the annular groove of cold wind shroud 8 is installed, and cold wind shroud 8 is provided with shifting block mechanism 5; Wherein, cold wind shroud 8 is parts of a periphery thickening, and periphery is provided with annular groove, together with this annular groove is embedded in the annular groove of kilneye cap iron 7, makes kilneye cap iron 7 and cold wind shroud 8 contact positions form two seals.
