Abstract
The utility model relates to an external heating rotary kiln, which comprises a rotary cylinder which is driven by an electromotor and a speed reducer. The utility model is characterized in that the speed reducer can drive both ends of the rotary cylinder simultaneously through a transmission member; both ends of the kiln are sealed by friction rings; pressure between a movable and a still sealing rings is supplied by a hydraulic cylinder; water cooling devices are installed on the positions of the hydraulic cylinder and a piston. Both ends of the body of the rotary cylinder are driven simultaneously, so that the body of the rotary cylinder is under a uniform torque force, and the service life of the rotary cylinder can be prolonged. Both ends of the body of the rotary cylinder are sealed by the sealing rings which are driven by the hydraulic cylinder, so that pressing force is stable and has elasticity, and the pressing force on sealed positions can not change so as to ensure the sealing performance of equipment.
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 furnace burning carbon acid salt ore, when obtaining soild oxide, can reclaim pure carbon dioxide, patent documentation ZL97232399 is disclosed to be exactly a kind of outer heating rotary furnace of burning carbon acid salt ore, there is following shortcoming in this rotary furnace: 1, the kind of drive of rotary kiln adopts the gear-driven version of an end, adopt this kind of drive, suffered torsion when cylindrical shell rotates, end at the gear place is maximum, reduce gradually to the other end along cylindrical shell, because of the cylindrical shell middle part is in stove, be subjected to the heating of 1100-1200 ℃ of high temperature, the ability of opposing stress reduces greatly, therefore the gear-driven mode of an end, make the most weak middle part of cylindrical shell opposing stress suffer torsion over half, make cylindrical shell under the state of hot operation, be easy to be damaged and reduce service life.2, the asbestos packing box structure is adopted in the movable sealing at cylindrical shell two ends, though installed bellows and roller additional at relevant position, scraping group and blocking group when partly eliminating cylindrical shell off-centre, but in order to prevent the increase of rotary resistance under the high temperature, asbestos in the packing case can not be adorned too tightly, when this just makes the cylindrical shell running eccentric, the asbestos of one side are pressed very tightly, and the asbestos of opposite side are very loose, the slit occurs between asbestos packing and the rotating cylinder, cause and leak out, dust in the cylindrical shell releases with air-flow, causes air pollution, and part drops in the slit, increase the cylindrical shell running resistance, influence the operate as normal of equipment.
The purpose of this utility model provides a kind of novel outer heating rotary furnace, and it can overcome existing shortcoming in the prior art, improves the service life of cylindrical shell, improves the sealing property at cylindrical shell two ends.
The purpose of this utility model is achieved in that it comprises the revolving drum that is driven by motor, decelerator, it is characterized in that decelerator drives the revolving drum two ends simultaneously by drive disk assembly, the drag ring sealing is all adopted at the two ends of kiln, and the pressure between the dynamic and static sealing ring provides by hydraulic cylinder, and is provided with water cooling plant at hydraulic cylinder and piston place.
Advantage of the present utility model is owing to drive the cylindrical shell two ends simultaneously, so the suffered torsion in cylindrical shell two ends equates half of suffered acrotorque when being an end transmission, and two ends are big, middle little, the service life that can improve revolving drum greatly.Because the sealing ring type sealing is adopted at the cylindrical shell two ends, between sealing device and cylindrical shell, can leave bigger gap, so can not produce the phenomenon of scraping group and card group, the thrust that is provided by hydraulic cylinder is stable simultaneously, and retractility is arranged, so the thrust of sealing place is changed, levied the sealing of discharge end and the normal operation of equipment thereby protect.
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 vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Fig. 4 is the structure cutaway view of discharge end.
Fig. 5 is the structure cutaway view of feed end.
With reference to Fig. 1, the 1st, revolving drum, the outside of revolving drum is furnace wall 2, it between them heater, the 3rd, the feed end rolling ring, it with the flange 16 of revolving drum between be connected with screw, the other end of rolling ring is connected with screw with the inner ring of gear wheel 5, the 4th, the discharge end rolling ring, fix with screw with the flange 15 of revolving drum, its other end is screwed with the inner ring of another gear wheel 5 and links to each other, as shown in Figures 2 and 3, two transition gears 6 are meshed with the gear wheel 5 at revolving drum two ends respectively, and transition gear is pinion mate 8 simultaneously, and transition gear and pinion are respectively by bearing block 7 and 9 supportings, two pinion shafts link by the output shaft of shaft coupling 10 and connecting axle 11 and decelerator 12, motor 13 passes through connecting axle after decelerator slows down like this, pinion, transition gear and gear wheel drive the two ends of revolving drum simultaneously, drive revolving drum and rotate.
The ring packing structure of present embodiment discharge end as seen from Figure 4, on revolving drum, have flange 46, dynamic friction ring 33 is screwed with this flange and is connected, going out to have flange 36 on the feed bin 35, the hydraulic cylinder 20 of annular is screwed on flange 36, annular piston 23 is housed in cylinder body, end at the annular piston bar is fixed with static friction ring 31 surely with spiral shell, between dynamic friction ring and static friction ring, graphite annulus 32 is housed, 21 and 22 is sealing rings of annular hydraulic cylinder among the figure, and overheated in order to prevent hydraulic cylinder, annular hydraulic cylinder and annular piston all are provided with waterway, figure number is respectively 38 and 39,24 is water inlets among the figure, the 25th, and delivery port, the inner chamber of annular hydraulic cylinder is connected with accumulator 27 by tube connector 26, hydraulic oil is housed in the accumulator, and be provided with Pressure gauge 28, advance, gate valve 29 is equipped with in the gas outlet, and accumulator is provided with oil filler 30,18 is hydraulic cylinder bearings among the figure, the 37th, and the carbon dioxide suction pipe.
Fig. 5 is the ring packing schematic diagram of feed end, its structure is identical substantially with the structure of discharge end, its difference is that its dynamic friction ring 33 is screwed on the flange 47 of revolving drum end, and the outer flange 42 of the feed pipe of annular hydraulic cylinder 20 usefulness screws and batcher 41 is fixedly linked, the support plate 43 usefulness spiral shell Dingan County that are welded on the hydraulic cylinder are contained on the bearing 44, and screw feeder pipe 45 passes annular hydraulic cylinder and annular piston inserts in the rotating cylinder.
In order to prevent that static friction ring and annular piston servo-actuated drag ring from together rotating, be provided with pull bar 40 in the present embodiment, pull bar penetrates in the hole by 20 4 jiaos of annular hydraulic cylinders, fixes with the end of screw and annular piston 23.
The operation principle of annular hydraulic cylinder and drag ring sealing is as follows: at first open oil filler 30, hydraulic oil is added in the accumulator 27, hydraulic oil enters annular hydraulic cylinder inner chamber 34 by tube connector 26, in liquid level reaches accumulator during about 1/5th positions, the sealing oil filler, inlet, outlet links to each other with air pump, open gate valve 29, in accumulator, inflate, when reaching certain pressure in the accumulator, hydraulic oil promptly forces annular piston to stretch out cylinder body, makes the static friction ring compress the dynamic friction ring, realizes the purpose of sealing.
14 is riding wheel apparatus among the figure.
