Abstract
A rotary kiln for calcining, oxidizing or reducing bulk or slurry materials features that its sealing unit is composed of axial and radial sealing units, and a sliding mechanism with rolling friction as its sliding surface is designed for reducing friction resistance. The kiln body conductive ring mechanism adopts a sliding guide rail and a guide wheel which can move back and forth, when the rotary kiln works, a carbon brush arranged on the sliding guide rail can be always kept on the same central line with the conductive ring on the kiln body, so that the carbon brush can be kept in good contact with the conductive ring, the temperature of each working section of the kiln body can be accurately reflected, and the kiln body conductive ring mechanism is widely applied to industrial departments of metallurgy, chemical industry, building materials, refractory materials, paper making and the like.
Description
The utility model belongs to a kind of and bulk material or pasty material is carried out roasting, the new-type rotary kiln of oxidation or reduction.Be widely used in industrial departments such as metallurgy, chemical industry, building materials, refractory material, papermaking.
During rotary kiln work, its cylindrical shell rotates around central axis, and kiln hood, kiln boot then remain static.Between the cylindrical shell of motion and static kiln hood, kiln boot, exist a dynamic seal (packing) problem.Rotary kiln is full of high-temperature gas in working order the time in the kiln, and gas leaks from this dynamic seal (packing) easily, causes environmental pollution and energy consumption to raise.When rotary kiln was in the negative pressure duty, ambient atmos was then scurried in the kiln from this dynamic seal (packing) easily, destroyed the perfect condition of technology, caused energy consumption to raise and technic index decline.The hermetically-sealed construction that present traditional rotary kiln adopted roughly is divided into labyrinth type, axially contact, contact etc. radially, has different problems separately.Big as seal clearance, frictional resistance is big, and complex structure is installed difficulty, and manufacturing cost is high.Compare strict process for seal request, the hermetically-sealed construction that traditional rotary kiln adopted can't satisfy the requirement of technology.In addition, for accurately operating rotary kiln, obtain the ideal technology index, at each work section of kiln body temperature thermocouple and kiln body blower fan are installed respectively, temperature measurement signal and power supply are to transmit by being installed in kiln conducting ring mechanism on one's body.In rotary kiln when work,, because the cylindrical shell thermal expansion, it is improper that the support roller group is adjusted, and the variation of coefficient of friction between rolling ring and the support roller, causes the reciprocal play of cylindrical shell.Present traditional conducting ring mechanism that rotary kiln adopted, the support body that carbon brush all will be installed is fixed on the basis, because the reciprocal play of cylindrical shell causes conducting ring and carbon brush loose contact, makes temperature measurement signal react inaccuracy, so that can not reflect the working of a furnace in the rotary kiln exactly, influence technic index.Therefore, the sealing device between cylinder of rotary kiln and kiln hood, the kiln boot, and be installed on conducting ring mechanism on the cylindrical shell, and then be the key of rotary kiln, whether its structure is reasonable, will directly influence the technological operation and the technic index of rotary kiln.
The operation principle of rotary kiln is: the cylindrical shell that kiln lining is housed is by transmission device, and rolling ring drives does the low speed revolution, and the support roller group then is used for supporting cylinder.Because cylindrical shell tilts to install, band gear wheel support roller group not only play supporting role to cylindrical shell, also can carry out spacing to the reciprocal play of cylindrical shell.Burner is installed in the kiln head box end, material is heated to temperature required by Fire Radiation.Material joins in the cylindrical shell from the tremie pipe of kiln boot, and during the cylindrical shell revolution, material is moving when circumferentially rolling vertically in the kiln, and material obtains heating in moving process, through physics and chemical change, become qualified products and discharge from the kiln head box end.Conducting ring mechanism then is used for transmitting temperature measurement signal and power supply.For preventing in the kiln that gas leaks, between rotating cylinder and static kiln head box, kiln boot, sealing device is housed.
The purpose of this utility model provides a kind of new-type rotary kiln with novel sealing device and kiln body conducting ring mechanism.
For achieving the above object, its technical scheme mainly comprises following two large divisions:
One. sealing device is by holddown spring 12, axial sealing ring 13, trajectory slide block 14, radial direction seal ring 15 critical pieces are formed, its special character is: adopted axially the mode that combines with contact seal radially, and the slide mechanism that to have designed a kind of its sliding surface dexterously be rolling friction, reduced frictional resistance.
The operation principle of this device is: when cylindrical shell 3 work, produce reciprocal play, make radial direction seal ring 15 on the trajectory slide block, also move back and forth, for its radial direction seal ring 15 end faces are fitted tightly, uniform a plurality of holddown springs 12 on kiln head box 2 circumference, its number is decided according to barrel dliameter size, is welded in the trajectory slide block 14 on the kiln head box 2, makes the slip that radial direction seal ring 15 can be nimbly and freely.For radial direction seal ring 15 can be moved back and forth, between kiln head box 2 and radial direction seal ring 15, produced seal clearance.Therefore this device has designed axial sealing ring 13, to guarantee the tightness of sealing.
Two. kiln body conducting ring mechanism is by frame 16, rail plate 17, carbon brush 18, conducting ring 19, directive wheel 20 critical pieces are formed, and its special character is: adopted the rail plate 17 and directive wheel 20 that can move back and forth.
The operation principle of this mechanism is: frame 16 usefulness foundation bolts are fixed on the basis, a plurality of carbon brush 18 are housed, and rail plate 17 bases of directive wheel 20 are fixed on the frame 16, and the carbon brush number is decided by arts demand, conducting ring 19 is installed on the cylindrical shell 3, and the conducting ring number is corresponding with the carbon brush number.When cylindrical shell 3 work, produce reciprocal play, the directive wheel 20 that nestles up conducting ring 19 sides drives rail plate 17 and moves back and forth with conducting ring 19 along with cylindrical shell 3 reciprocal plaies.Make carbon brush 18 remain on the same center line with conducting ring 19 all the time like this, and carbon brush 18 is fitted tightly all the time with conducting ring 19, make it to keep excellent contact by the holddown spring on the carbon brush 18.
