Abstract
A kind of rotary kiln sealing structure with compound seal piece, to be solved the problem of roasting diaphragm seal of the material with corrosive gas corrodes；The technical solution of the utility model is that the end of rotating cylinder is inserted in air-cooled set, is provided with seal closure on air-cooled set outer wall, the position that right angle is projected as between seal closure and air-cooled set is provided with diaphragm seal；The diaphragm seal uniformly overlay it is air-cooled put, in fish scale-shaped around it is air-cooled set stack one week；The diaphragm seal is layer structure, and its side is stainless steel plate, and opposite side is the heat resistant rubber composite construction alternate with heat-and corrosion-resistant potsherd.It is notable as wear-and corrosion-resistant effect using ceramic material；Ceramics and stainless steel are vulcanized firm using heat resistant rubber, the rigidity of ceramics has not only been utilized but also has utilized the flexibility of stainless steel substrates and rubber, so that diaphragm seal has float flexible.Solve the sealing problem that kiln is calcined corrosive materials.The features such as the utility model also has simple in construction, simple installation, strong adaptability.
Description
Technical field
The utility model belongs to seal of rotary kiln technical field, and more particularly to a kind of rotary kiln with compound seal piece is used
Sealing structure.
Background technology
The sealing of swinging cylinder class is always that kiln class design process wants what emphasis considered, and in operation process, cylinder is back
What transhipment was moved, and the cover body that feeds and discharge is stationary parts, the problem of both junctions are carried out being sealed to must take into consideration.
Due in manufacturing process, cylinder rolls the error that always there is radial direction, according to millesimal standard error
Difference, it has been very big circular runout to be reflected in drum surface.And cover body etc. belongs to rigid member, so flexible sealing must be used
Part, which partially radially beats this, to be dissolved；In cylinder turning course, diaphragm seal is close to cold wind shroud surface, with drum surface
Radial floating, so as to realize the safe operation of equipment.
It can be calcined containing corrosive material because rotary kiln belongs to Thermal Equipment, inside it, and the flue gas meeting after being calcined
Overflowed with air-flow along diaphragm seal, general flexible sealing is fish scale lamellar seal, and seal steel plate is directly fitted with cylinder, corrodes gas
Body directly contacts seal steel plate after overflowing, so as to cause the burn into of diaphragm seal to fail.
Based on above reason, it is necessary to design a kind of kiln wear resistant corrosion resistant novel seal, it is corrosive so as to solve band
The problem of material roasting diaphragm seal of gas corrodes.
The content of the invention
The purpose of this utility model is to provide a kind of rotary kiln sealing structure with compound seal piece.
The purpose of this utility model is achieved in that the end of rotating cylinder is inserted in air-cooled set, on air-cooled set outer wall
Seal closure is provided with, the position that right angle is projected as between seal closure and air-cooled set is provided with diaphragm seal；The diaphragm seal is uniformly folded
Be placed on it is air-cooled put, in fish scale-shaped around it is air-cooled set stack one week；The diaphragm seal is layer structure, and its side is stainless steel
Plate, opposite side is the heat resistant rubber composite construction alternate with heat-and corrosion-resistant potsherd.
The utility model has the advantages that：It is notable as wear-and corrosion-resistant effect using ceramic material；It will be made pottery using heat resistant rubber
Porcelain and stainless steel vulcanization are firm, not only using the flexibility that is rigid but also utilizing stainless steel substrates and rubber of ceramics, so that diaphragm seal
With float flexible.Solve the sealing problem that kiln is calcined corrosive materials.The utility model also has simple in construction, installation letter
Just, the features such as strong adaptability.
Brief description of the drawings
Fig. 1 is general structure simplified schematic diagram of the present utility model；
Fig. 2 is Fig. 1 section structure schematic diagram；
Fig. 3 is the section structure schematic diagram of diaphragm seal；
Fig. 4 is Fig. 3 top view；
Fig. 5 is diaphragm seal mounting structure schematic diagram.
The utility model is described in further detail by example below in conjunction with accompanying drawing, but following examples is only
The utility model example therein, does not represent the rights protection scope that the utility model is limited, of the present utility model
Rights protection scope is defined by claims.
Embodiment
Example 1
Referring to Fig. 1 ~ 5, the end insertion of rotating cylinder 1 is air-cooled to be covered in 2, is provided with seal closure 4 on air-cooled set outer wall, is sealed
The position that right angle is projected as between cover and air-cooled set is provided with diaphragm seal 3；The diaphragm seal uniformly overlay it is air-cooled put, in fish
Squamous is stacked one week around air-cooled set；The diaphragm seal is layer structure, and its side is stainless steel plate 4, and opposite side is heat-resisting rubber
The composite construction alternate with heat-and corrosion-resistant potsherd 6 of glue 5.
Diaphragm seal is vulcanized onto stainless steel substrates using potsherd and heat resistant rubber, using potsherd is wear-resisting, high temperature resistant, anti-corruption
Corrosion energy, in combination with the flexibility of rubber and thin stainless steel substrates, realizes contact seal.Top is fixed with fastening bolt, middle part
And bottom is tied tight with steel wire rope, so as to reduce radially wobbling for kiln cylinder body using the flexibility of compound seal piece, compound seal is utilized
Erosion of the Wear-resistant corrosion-resistant resistance kiln internal corrosion flue gas of piece to diaphragm seal.So as to ensure that the sealing effectiveness of kiln and use
Life-span.
