Further, the sealed rotary device is contacts frictional sealing device, in the afterbody and ball milling section of drying section Head sets dead turn respectively, and two dead turns contact with each other and fill lubricant.
Further, the transmission device of the drying section is constant speed transmission device, including ring is fixed on outside drying section cylinder The first gear in portion, the first travelling gear, reductor and the motor engaged with first gear, the motor pass through reductor The first travelling gear is driven, first gear is driven drying section rotation.
Further, the transmission device of the ball milling section is speed-regulating actuator, including ring is fixed on outside ball milling section cylinder The second gear in portion, the second travelling gear, reductor and the motor engaged with second gear, the motor pass through reductor The second travelling gear is driven, second gear is driven the rotation of ball milling section.
Further, the ball milling intersegmental part is equipped with steel ball, and ball milling segment trailer is blocked provided with the hollow out only passed through for siccative Sieve plate.
Further, the sieve plate of blocking is the steel plate with parallel crack, and the side of the steel plate is provided with reinforcement.
Further, the sieve plate of blocking is detachably arranged on ball milling intersegmental part support by bolt.
Further, the discharging section is provided with the flue of smoke evacuation.
Beneficial effect:Wet feed enters rotary drum dryer, drying section rotation from feed zone, and hot blast section is sent into hot blast, and wet feed exists Moved in rotary course to ball milling section, drying is completed in moving process;Then siccative enters ball milling section, complete in the presence of steel ball Into ball milling, the fines for meeting granularity requirements enters discharging section by sieve plate of blocking, and not meeting the material of granularity requirements can not pass through Baffle plate, continue ball milling;Fines is discharged from the discharging opening of discharging section, into next process.Flue dust, can after rough dusting Cleaner is discharged into from the flue of discharging section.
The utility model directly carries out ball milling after wet feed drying, can not only continue to dry in mechanical milling process, increases Drying machine drying ability, and later stage ball milling, screening, dedusting, the investment of transport can be reduced.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation Example.
Embodiment:A kind of rotary drum dryer with ball milling function, as shown in figure 1, the hot blast section being connected including axial order 1st, feed zone 2, drying section 3, ball milling section 4 and discharging section 5.The stem of feed zone 2 is provided with charging aperture 6, and the afterbody of discharging section 5 is set There is discharging opening 15.
The junction of drying section 3 and ball milling section 4 sets sealed rotary device 9, specifically, in the afterbody and ball of drying section 3 The head of mill section 4 sets dead turn respectively, and two dead turns contact with each other and fill lubricant, it is ensured that drying section 3 and ball milling The rotation of section 4 is independent of each other, and flue dust is not leaked in sealing.
The middle part of the cylinder of drying section 3 is provided with constant speed transmission device 17, is included in the first gear that ring is fixed outside cylinder 8th, the first travelling gear, reductor and the motor engaged with first gear 8, motor drive the first driving cog by reductor Wheel, first gear 8 is set to drive the cylinder of drying section 3 to be rotated with fixed speed.The both ends of drying section 3 are all installed by the rolling ring around cylinder 7, rolling ring 7 is carried on tug device 16, for supporting the rotation of whole drying section 3.
