At least two spaced supporting wheel systems in front and back are housed on described rotary kiln bearing, each supporting wheel systems comprises two support wheels that are oppositely arranged, cylinder of rotary kiln is positioned at the middle upper part of two support wheels, rotary kiln power set comprise rotary kiln drive motors, on the power output shaft of rotary kiln drive motors, driving gear is housed, the driven gear ring with driving gear engagement is housed on cylinder of rotary kiln.
Each material turning cylinder is axially spliced along cylinder of rotary kiln by the cylinder of multistage closed at both ends, and a plurality of thermocouples in the cylinder that stretches into respectively each section of material turning cylinder are housed on cylinder of rotary kiln.
The cross section semicircular in shape of described material turning cylinder and the outer wall surface of expression in cylinder of rotary kiln are circular-arc.
Adopt after said structure, haydite after moulding enters in cylinder of rotary kiln through rotary kiln feed pipe, rotary kiln power set drive cylinder of rotary kiln to rotate, flame projector is to flame in cylinder of rotary kiln, under the air inducing effect of exhaust blower, heat flows forward from cylinder of rotary kiln rear end, and the haydite of while drying forming, haydite is under the driving of the cylinder of rotary kiln rotating drives, and when rotating with cylinder of rotary kiln, material turning cylinder the haydite that is positioned at cylinder of rotary kiln intracavity bottom can be stirred to device, stir the round and smooth rolling of haydite meeting in process, thereby effectively avoid the fracture phenomena occurring because of rigid stirring, the haydite having stirred forms waterfall shape and falls under the effect of kicking up of material turning cylinder, it is omnibearing cooling to haydite when hot blast flows.
In sum, the utility model has changed the pattern that rigidity is stirred haydite, adopts the material turning cylinder of rounding off to stir haydite, has advantages of that haydite is heated evenly and effectively avoids haydite breakage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the structural representation of a kind of most preferred embodiment of the utility model;
Fig. 2 is the cutaway view along B-B line in Fig. 1.
The specific embodiment
The formula rotary kiln that falls of waterfall as shown in Figure 1, the described waterfall formula rotary kiln 7 that falls comprises rotary kiln bearing 71 and is rotatably connected on the cylinder of rotary kiln 72 on rotary kiln bearing 71, the rotary kiln power set that drive cylinder of rotary kiln 72 to rotate are also housed on rotary kiln bearing 71, at least two spaced supporting wheel systems in front and back are housed on rotary kiln bearing 71, each supporting wheel systems comprises two support wheels that are oppositely arranged, cylinder of rotary kiln 72 is positioned at the middle upper part of two support wheels, cylinder of rotary kiln 72 is slightly tilted to lower setting after going to, be that the rear end height of revolving sleeve cylindrical shell 72 is a little less than its front end height, being convenient to haydite rearward moves, rotary kiln power set comprise rotary kiln drive motors 711, on the power output shaft of rotary kiln drive motors 711, driving gear is housed, driven gear ring with driving gear engagement is housed on cylinder of rotary kiln 72, when rotary kiln drive motors 711 drives driving gear to rotate, cylinder of rotary kiln 72 rotates, at least three material turning cylinders 79 that extend axially and be periphery along its cross section along cylinder of rotary kiln 72 are housed on the inwall of cylinder of rotary kiln 72, it is semicircle as shown in Figure 2 that the cross section of material turning cylinder 79 is, and its outer wall surface is circular-arc, above-mentioned outer wall refers to and is arranged in cylinder of rotary kiln 72 to the outer wall of portion's section of its inner chamber extension, thereby be conducive to haydite round and smooth rolling in the process of drying, prevent the haydite disrepair phenomenon that collides with and occur because of rigid, and the setting of material turning cylinder 79 flows down the waterfall shape that is that the haydite after moulding can be round and smooth in stirring process, thereby haydite is carried out to omnibearing stereo oven dry.
