Abstract
The utility model relates to an external heating rotary kiln which adopts a worm distributor for feeding in stead of a diagonal tube for feeding. Meanwhile, a discharging bin is installed on a corrugated tube with elasticity, wheels are arranged under a storing bin, and a pumping tube is installed at the upper part of the discharging bin. The utility model raises the fill factor of the kiln material in the kiln, and the fill factor is adjustable by adopting the structure, so the utility model can raise the production efficiency, simultaneously ensure the product quality, lower the heat consumption, eliminate the scraping and clamping for the discharging bin when a cylinder is eccentric, ensure the normal operation of the equipment and receive the carbon dioxide gas with high purity.
Description
The utility model is a kind of outer heating rotary kiln that is used for the burning carbon acid salt ore.
Adopt outer heating rotary kiln baking carbonate ore, when obtaining soild oxide, can reclaim pure carbon dioxide.Patent documentation CN10490324 is disclosed to be exactly a kind of outer heating rotary kiln of burning carbon acid salt ore.There is following shortcoming in this rotary kiln: 1, the feeding manner of rotary kiln adopts the version of " feed pipe tilts to put in the rotary kiln ".Adopt this feeding manner, if the bed of material is thicker, along with the rotation of cylindrical shell, just the material in the kiln spills from the feed end of kiln, so the bed of material in the kiln can not be thick, the volumetric efficiency of furnace charge in kiln generally is not more than 0.1.And according in the past experience, for the highest, so the mode of inclined tube charging influenced the production efficiency of stove to the volumetric efficiency of furnace charge 0.3 o'clock output.
2, revolving drum is that asbestos packing contacts sealing with the sealing that kiln hood goes out feed bin.Because revolving drum is longer, the temperature difference of cylindrical shell is bigger, so the cylindrical shell two ends easily produce off-centre, swing when cylindrical shell is rotated, cause and " scraping group " of going out feed bin or " card group " phenomenon, make the asbestos packing wearing and tearing very fast, cause gas leakage, make kiln can not keep operate as normal.3, the carbon dioxide in the kiln is to extract out from " chimney jambs ", and the reason chimney jambs has the junction, many places between the kiln tail, the air that all might bleed, the purity of reduction carbon dioxide.
The purpose of this utility model provides a kind of novel outer heating rotary kiln, it can overcome existing shortcoming in the prior art, improve the volumetric efficiency of furnace charge, improve the sealing property that between feed bin and the revolving drum, prevent the appearance of " scraping group " and " card group " phenomenon, improve the purity of carbon dioxide.
The purpose of this utility model is achieved in that it comprises a revolving drum, revolving drum is by motor, decelerator drives, the feed end that it is characterized in that revolving drum is equipped with dynamic sealing device, the moving axis of movable sealing is a hollow shaft, the feed pipe of screw(-type) feeder enters revolving drum by hollow shaft, the discharge end of revolving drum is set with out feed bin, go out the feed bin bottom discharge nozzle is arranged, discharge nozzle stretches in the storage bin, one end and the discharge nozzle outer wall of a bellows are fixedly linked, end is fixedly linked with storage bin in addition, exhaust tube stretches into revolving drum by going out feed bin, pipe is outer to be set with bellows, between bellows one end and the exhaust tube outer wall sealing ring is housed, the holding in addition and go out feed bin and link to each other with flange of bellows.
For guaranteeing the sealing property of feed end, the feed end dynamic sealing device adopts the movable sealing of spherical axle, between its motionless axle sleeve and the feed pipe bellows is housed.Can also be below storage bin the installation roller, further to reduce the harmful effect that cylindrical shell off-centre is caused.
The utility model is compared in prior art, and following advantage is arranged:
1, owing to adopted screw feeder mechanism, so the activity coefficient of furnace charge in stove is improved, and it is adjustable, so can enhance productivity, the quality of product can be guaranteed simultaneously, and can reduce hear rate, spherical axle dynamic sealing device and bellows can avoid because the leakage that cylindrical shell vibration and distortion are produced.
2, owing to have roller below the storage bin, storage bin with go out bellows is housed between the feed bin, so eliminated cylindrical shell when eccentric to go out feed bin scrape group and card is helped, guaranteed the normal operation of equipment.
3, exhaust tube inserts in the revolving drum by going out feed bin, and the carbon dioxide in the kiln is directly taken away, has reduced the chance of many leakages, so can receive highly purified carbon dioxide.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is a general illustration of the present utility model.
Fig. 2 is the structure cutaway view of feed end among Fig. 1.
Fig. 3 is the cutaway view of discharge end among Fig. 1.
Fig. 4 is the left view of Fig. 3.
As shown in the figure, the 1st, revolving drum, the revolving drum outside is furnace wall 2, heater is housed between them, and the right side among Fig. 1 is a feed end, and 8 is screw(-type) feeders among the figure, by Fig. 1 and Fig. 2 as seen, motor 5 rotates by driving revolving drum 1 after the gear reduction, and the outer ring of gear wheel 35 and rolling ring 3 is screwed and links, and links with screw with flange 15, flange 15 and revolving drum welding, the inner ring of rolling ring 3 is connected with the moving axis 14 of dynamic sealing device with screw, and moving axis 14 is a hollow shaft, and outer surface is spherical, the spherical axle sleeve that matches with it partly overlaps 11 by left half axle cover 13 and right axle and forms, between they and the spherical axle asbestos packing 12 is housed, 10 is bellowss among the figure, and two ends are welded with flange, one end flanges and right axle shaft cover link with screw, end is fixing with flange 9 in addition, and flange 9 is welded on above the feed pipe 31
By Fig. 1 and Fig. 3, Fig. 4 as seen, welding between flange 16 and the revolving drum 1, link with screw again and between the rolling ring 4 simultaneously, be set with out feed bin 21 in the end of revolving drum, the dynamic sealing device of discharge end is installed in out between feed bin 21 and the rolling ring 4, motionless cover 17 with go out feed bin and link to each other with screw, and moving cover 18 is screwed in rolling ring 4, in the moving cover asbestos packing 19 is housed, asbestos packing is equipped with gland 20 outward, gland 20 is screwed on moving cover 18, below going out feed bin, be provided with discharge nozzle 32, it extend in the storage bin 24, on discharge nozzle, be welded with a flange 22, the charging aperture of storage bin also has flange simultaneously, the flange at bellows 23 two ends promptly is installed between above-mentioned two flanges, roller 30 is housed below storage bin, the upper opening that goes out feed bin is equipped with flange 33, exhaust tube 27 stretches in the revolving drum thus, and the flange of bellows 25 1 ends and flange 33 usefulness screws fix, and the flange of end is screwed on female flange 26 in addition, asbestos packing 34 is contained in the female flange, compress with gland 28, the exhaust tube outer end is welded with flange 29, is used for linking to each other with extract system.
7 is riding wheel apparatus among the figure, by the weight of the whole rotating part of its bearing and turning kiln, because rotary kiln is tilted-putted, slided to a side by the effect of weight, so gear wheel 6 is installed, is used to prevent that cylindrical shell from gliding.
