Background technology
Rotary kiln refers to rotary calcining kiln.Cement kiln, chemical metallurgy kiln and limekiln can be divided into according to processing material difference,
Rotary drying kiln etc..Material carries out high-temperature calcination in kiln body, and typical temperature is between 600-1200 DEG C.Sealing device is revolution
The critical component of kiln, between rotating cylinder and actionless cover body, effect is environment in kiln is isolated from the outside for it,
It is main to prevent from leaking out outside kiln with powder in kiln in cold air suction kiln.Because there is revolution, deflection, axial etc. again in kiln head and tail end
Miscellaneous movement, sealing need axial direction, the radial clearance for overcoming rotary kiln to be produced in operating.If insulation is bad to reduce Secondary Air
Temperature, causes thermal loss；If leaked out, not only fuel cannot fully burn, but also can influence kiln ventilation, increase heat consumption, shadow
Ring yield.So the quality of seal of rotary kiln effect directly affects yield, heat consumption, power consumption, pollution and technique etc..
It is more using sealing lamellar seal both at home and abroad at present.Rotary kiln is normally pressurized operation, but discharge end often goes out in kiln
Now instantaneous high positive pressure, diaphragm seal is started by positive pressure impact in traditional structure at this time, is followed the string in the course of time, material leakage of leaking out is tight
Weight, while partial material enters annular seal space, aggravates sealing pad wear, service life is reduced.Therefore how sealing effect is improved,
A great problem in rotary kiln design.
The content of the invention
The utility model provides a kind of rotary kiln biserial graphite block sealing device, the biserial graphite block sealing device by
Biserial graphite block sealing device is set between the cylinder and seal closure of rotary kiln, which adapts to rotary kiln operating and go out often
Existing bounce, positive pressure, the special operation condition not waited coaxially, improves sealing effect, improves the rotary kiln thermal efficiency and yield rate.
The purpose of this utility model is achieved through the following technical solutions：
A kind of rotary kiln biserial graphite block sealing device, the sealing device include tension device, sealed support, interior gear
Plate, graphite block, outer baffle, bolt adjust clamp device, jackscrew group, wedge block, and the graphite block is square, and the wedge block is
Trapezoidal, graphite block and wedge block cross arrangement in same circumferential plane, front and rear two rows altogether, form biserial graphite block group, biserial
The both sides of graphite block group are clamped with Internal baffle and outer baffle are front and rear respectively, and the front and rear sides of Internal baffle 3 and outer baffle 5 pass through bolt
Adjusting clamp device, jackscrew group are fixedly clamped, and jackscrew group is arranged on bolt and adjusts clamp device top；There are bolt in all mechanisms
It is fixed；Tension device is equipped with outside the graphite block makes graphite block be close to barrel.
A kind of rotary kiln biserial graphite block sealing device, the graphite block biserial intersects dislocation arrangement, described
Sealed support is segmented, can be divided into 4-8 sections, sealed support sectional Assembling.
The advantages of the utility model is with effect：
1st, its simple in structure, sealing effect height of the biserial graphite block sealing device of the utility model, convenient to install and maintain, stone
Ink stick heat resistant and wear resistant is strong, easily replaces.
2nd, the sealing device of the utility model adapts to the bounce that rotary kiln operating occurs often, can adapt to rotary kiln and turns
Move, axial float, circular runout, any operating mode in the scene such as high-temperature instantaneous positive pressure, improves sealing effect, improve the rotary kiln thermal efficiency
And yield rate.
3rd, the biserial graphite block sealing device structure of the utility model is stablized, and installation is simple, reliable, and theory is not leaked
Wind, non-material leakage, adapt to any operating mode.Service life is grown, and high temperature positive is without influence, and consumptive material graphite block is replaced simply, nearly specification
The graphite block of specification of the same race can be used by returning brickkiln, can be mass making.

Embodiment
The utility model is described in detail with reference to embodiment.
The utility model provides a kind of rotary kiln biserial graphite block sealing device, which includes tension device 1, close
Seal stent 2, Internal baffle 3, graphite block 4, outer baffle 5, bolt adjust clamp device 6, jackscrew group 7, wedge block 8,.The sealing branch
Frame 2 is segmented, can be divided into 4-8 sections, Assembling, the graphite block 4 is square, and the wedge block 8 is trapezoidal, graphite block 4
With the cross arrangement in same circumferential plane of wedge block 8, biserial graphite block group is formed, the both sides of biserial graphite block group are respectively with interior
The front and rear sides of baffle 3 and the front and rear clamping of outer baffle 5, Internal baffle 3 and outer baffle 5 pass through bolt and adjust clamp device 6, jackscrew group
7 are fixedly clamped, and jackscrew group 7 is arranged on bolt and adjusts clamp device top；All mechanisms have bolt to fix；The graphite block 4
Outside is equipped with tension device 1, allows graphite block to be close to barrel.
Barrel 9 is rotating mechanism when rotary kiln runs well, and biserial graphite block sealing device is static mechanism, graphite block
4 is staggered for biserial, and sealing function is played with 9 relative motion of barrel.Tension device 1 winds tension outside graphite block 4,
Make the axis produced the problems such as being attached in barrel 9, prevent inadequate cylinder bounce and circularity, installation decentraction of graphite block 4 tightly
The material leakage of leaking out produced to circular runout.4 biserial of graphite block is arranged, such as Fig. 3, and centre is by 4 staggered row of wedge block 8 and graphite block
Row.Graphite block 4 is square, and wedge block 8 is trapezoidal, has so not only solved the problems, such as graphite block abrasion downslide but also solved radially to leak out
Problem, while the big low-angle of wedge block 8, close 4 graphite block of specification rotary kiln can be changed according to the rotary kiln of different size
It is generally applicable to accomplish that consumptive material batch production makes saving processing cost.
9 the inside temperature of barrel is usually 800-1200 DEG C when rotary kiln operates, and can produce positive pressure effect, with interior during installation
Baffle 3 and outer baffle 5 are installed on graphite block 4 on sealed support 2, keep radially vertical with barrel 9.
Consider field working conditions and machining accuracy problem, the utility model sets a lever principle, is adjusted and fastened by bolt
Device 6 is used as fulcrum, is suitably adjusted with jackscrew group and clamps graphite block 4, and in addition sealed support 2 can divide 4-8 sections for segmented, scene
Assembling, reduces difficulty of processing, saves shipment and delivery cost.
