Abstract

The utility model discloses a rotary sealing mechanism for a kiln hood and a kiln body on coal decomposition equipment. The rotary sealing mechanism comprises a sealing ring area and a fixed projection which are integrated with the kiln hood. The sealing ring area is internally provided with a graphite packing. A high-temperature sealing problem can be better settled. The outer circumference of the kiln body is provided with a pressing plate which is movably connected with the graphite packing. The pressing plate is movably connected with the fixed projection through a bolt. The bolt connection mode facilitates mounting, maintenance and detachment. The bolt for connecting the pressing plate and the fixed projection is provided with an elastic gasket. The compression degree of sealing can be furthermore improved. A clearance exists between the pressing plate and the fixed projection after compression. A problem of inferior sealing effect caused by abrasion in the using process of packing can be settled through adjusting the bolt, thereby obtaining high convenient and high effectiveness.

Description

The rotatory sealing mechanism of kiln hood and kiln body on the coal resolving device
Technical field
The utility model belongs in the large-scale heating kiln body auxiliary equipment technical field that adds, and is specifically related to the rotatory sealing mechanism of kiln hood and kiln body on a kind of coal resolving device.
Background technology
Current, rotary kiln device still is a kind of main equipment that must rely in the industrial production, in many production industries such as building materials, metallurgy, chemical industry, environmental protection, uses apparatus for rotating that solid material is carried out machinery, physical or chemical treatment widely.The application of rotary kiln originates from manufacture of cement, and it is put into production, very fast acquisition considerable economic.The invention of rotary kiln makes cement industry develop rapidly, has also promoted the research that people use rotary kiln simultaneously, and very fast rotary kiln is widely applied to many industrial circles, and more and more important in these are produced, and becomes the nucleus equipment that corresponding enterprise produces.Its technical performance and working order are determining quality, output and the cost of enterprise product to a great extent.In recent years, high temperature resistant, the corrosion resistant encapsulant of many kinds appears again in the elevated-temperature seal industry, such as the graphite packing, but because huge rotate relative of kiln hood with the kiln body, the encapsulant of utilization is in both rotatory sealings, the mode that a lot of different sealings are arranged, but all there is such-and-such problem inevitably.
The utility model content
The utility model provides a kind of can use well that sealing material, sealing effectiveness are splendid, the rotatory sealing mechanism of kiln hood and kiln body on the coal resolving device of long service life.
The rotatory sealing mechanism of kiln hood and kiln body on a kind of coal resolving device, be arranged on the contact site of kiln hood and kiln body, it comprises sealing ring district and fixed lobe with the kiln hood one, described sealing ring is provided with seal member in the district, the pressing plate that flexibly connects with described seal member is set on the excircle of described kiln body, and described pressing plate and described fixed lobe flexibly connect by bolt.
The dust seal circle is set between described seal member and the kiln hood.
Described seal member is the graphite packing.
On the bolt of described connection pressing plate and fixed lobe elastomeric pad is set.
After compressing, described connection pressing plate and fixed lobe have the gap between the two.
Because the rotatory sealing mechanism of kiln hood and kiln body on the utility model coal resolving device, it comprises sealing ring district and fixed lobe with the kiln hood one, described sealing ring is provided with the graphite packing in the district, can solve the elevated-temperature seal problem well, the pressing plate that flexibly connects with described graphite packing is set on the excircle of described kiln body, described pressing plate and described fixed lobe flexibly connect by bolt, bolted mode is convenient to install, maintenance and dismounting, on described connection pressing plate and the fixed lobe bolt elastomeric pad is set, can further improve the degree that compresses of sealing, after compressing, described connection pressing plate and fixed lobe have the gap between the two, can make the not good problem of sealing effectiveness that packing in use causes because of wearing and tearing by adjusting bolt, easily and effectively.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at rotatory sealing position in the utility model.
The specific embodiment:
As shown in Figure 1 and Figure 2: the rotatory sealing mechanism 3 of kiln hood and kiln body on a kind of coal resolving device, be arranged on the contact site of kiln hood 2 and kiln body 1, it comprises sealing ring district and fixed lobe 9 with kiln hood 2 one, described sealing ring is provided with seal member 6 in the district, the pressing plate 4 that flexibly connects with described seal member 6 is set on the excircle of described kiln body 1, described pressing plate 4 flexibly connects by bolt 5 with described fixed lobe 9, and bolted mode is convenient to install, is overhauled and dismounting.
Between described seal member 6 and the kiln hood 1 dust seal circle 7 is set, can solves the problem that a large amount of dusts that produce in the kiln body influence the primary seal effect.
Described seal member 6 is graphite packings, can solve the elevated-temperature seal problem well.
On the bolt of described connection pressing plate 4 and fixed lobe 9 elastomeric pad is set, can further improves the degree that compresses of sealing.
There is gap 8 between the two in described connection pressing plate 4 after compressing with fixed lobe 9, can solve the not good problem of sealing effectiveness that packing in use causes because of wearing and tearing by adjusting bolt, easily and effectively.
