Description
Technical field
This utility model relates to rotary kiln device, particularly to a kind of seal of rotary kiln structure.
Background technology
Rotary kiln, also known as rotary calcining kiln, can be divided into cement kiln, chemical metallurgy kiln and limekiln by processing material difference.Water
Stall is mainly used in calcination of cement clinker, point dry production cement kiln and the big class of wet production cement kiln two.Chemical metallurgy kiln is then
It is mainly used in the lean iron ore magnetic roasting of metallurgy industry steel plant；Chromium, josephinite oxidizing roasting；Refractory factory roasting high-aluminium vanadine
Ore deposit roasting grog, aluminium hydroxide；The class mineral such as chemical plant roasting chrome ore and chromite ore fine.Limekiln is used for roasting steel plant, ferrum
The active lime of Alloy Plant and light dolomite.Therefore rotary kiln is at many production industries such as building materials, metallurgy, chemical industry, environmental protection
In be widely used.
When rotary kiln uses in each big field at present, how to ensure that material does not leak when passing in and out hopper and have become as revolution
A subject matter in kiln use.Boiler tube in rotary kiln is to rotate, and hopper is static, it is therefore desirable to use dynamic close
Envelope.For this kind of movable sealing, traditional sealing means mainly has labyrinth seal, end face of flange to seal, fish scale lamination seals, filler
Seal.But, there is the shortcoming that sealing effectiveness is poor, device complicated or service life is short in traditional sealing means.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, good sealing effect, service life length seal of rotary kiln
Structure.
The technical scheme realizing this utility model purpose is: this utility model has boiler tube and hopper；Set on described boiler tube
There is sealing device；Described sealing device includes ring support and annular polyfluoroprene plate；Described ring support is fixedly installed on hopper；
Described annular polyfluoroprene plate is fixedly installed on a toroidal support, and annular polyfluoroprene plate is wrapped in the outer surface of boiler tube and forms sealing.
Above-mentioned sealing device includes two symmetrically arranged annular polyfluoroprene plates；Described annular polyfluoroprene plate is wrapped in the one of boiler tube
Hold the bending that deforms；Described ring support is provided with aerating oil filler；Described aerating oil filler is positioned at two annular polyfluoroprene plates
Between.
Above-mentioned hopper is provided with the bleeding point being connected with retracting device.
The outside of above-mentioned boiler tube is provided with thermal insulation layer；The outer surface that described annular polyfluoroprene plate is wrapped in thermal insulation layer is formed and seals.
This utility model has a positive effect: (1) this utility model simple in construction, easy for installation, and has very well
Sealing effectiveness；
(2) this utility model utilizes polyfluoroprene plate to seal, owing to polyfluoroprene plate has ozone ageing-resistant, high temperature resistant, resistance to, resistance to
The multifrequency natures such as fine vacuum oily, resistance to, acid and alkali-resistance, therefore substantially increase the service life of sealing device；
(3) Hmp grease or logical is injected in this utility model utilizes aerating oil filler cavity between two polyfluoroprene plates
Enter gas, the life-span of polyfluoroprene plate can be extended or increase sealing effectiveness；
(4) this utility model utilizes bleeding point can improve the sealing of hopper further.
Accompanying drawing explanation
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail this utility model, wherein

Seal apparatus 3 includes ring support 31, and ring support 31 is arranged with two annular polyfluoroprene plates 32；Described ring support 31 is fixed
It is arranged on hopper 2；Described annular polyfluoroprene plate 32 is fixedly installed on ring support 31；The outside of described boiler tube 1 is provided with heat insulation
Layer 11；The outer surface that described annular polyfluoroprene plate 32 is wrapped in stove thermal insulation layer 11 is formed and seals；Described annular polyfluoroprene plate 32 is wrapped in
One end of thermal insulation layer 11 deforms bending；Described ring support 31 is provided with aerating oil filler 33；Described aerating oil filler 33
Between two annular polyfluoroprene plates 32.
Described hopper 2 is provided with the bleeding point 21 being connected with retracting device.
Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect
Step describes in detail, be it should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, all should wrap
Within being contained in protection domain of the present utility model.
