The specific embodiment
Below in conjunction with accompanying drawing, further describe the specific embodiment of this patent.
As shown in Figures 1 to 3, circulation drum-type rapeseed dryer in a kind of material, comprise the cylinder 1 be arranged on frame 9, hot air apparatus and whirligig, described cylinder 1 is provided with air inlet 2, air outlet 14 and feed inlet and outlet 13, described feed inlet and outlet 13 is provided with the cover plate 15 of the described feed inlet and outlet of sealing, the air outlet of described hot air apparatus is connected with the air inlet of described cylinder, described cylinder 1 drives and rotates along axis by described whirligig, described feed inlet and outlet 13 is arranged on described air outlet 14 1 sides, direction from described air inlet 1 to air outlet 14 on the inwall of described cylinder 1 is provided with many lifting blades 17, described lifting blade 17 is provided with an angle with the axis of described cylinder 1, described angle makes material in described cylinder 1 14 move from air inlet 1 to air outlet along with described drum rotating, be fixed with feed back pipe 16 on described lifting blade 17, described feed back pipe 16 in the shape of a spiral and import be arranged on the air opening end of described cylinder 1 and be close to described cylinder 1 inwall, the outlet of described feed back pipe 16 is arranged on the air inlet end of described cylinder 1, the direction of rotation of described feed back pipe 16 enters into feed back pipe material while making described cylinder 1 rotation moves to the port of export from entrance point.
Described hot air apparatus comprises electric heater 3, warm-air pipe 4 and blower fan 6, and an end of described warm-air pipe 4 is connected with the air inlet 2 of described cylinder 1, and the other end is connected with described blower fan 6 air outlets, is enclosed with described electric heater 3 on described warm-air pipe 4.
Described whirligig comprises roller 7, roller shaft 8, motor 10, decelerator 11 and roller groove 18, the outer wall of described cylinder 1 is provided with a plurality of described roller groove 18 around described cylinder axis one circle, motor 10, decelerator 11 and roller shaft 8 are installed on described frame 9, on described roller shaft 8, roller 7 is installed, described motor 10 is connected with described roller shaft 8 by decelerator 11 and drives 8 rotations of described roller shaft, described roller shaft 8 is arranged on described cylinder 1 downside, described roller 7 is arranged in described roller groove 18, and described roller 7 drives described cylinder 1 rotation.
Described frame 9 is provided with blowpit 12, and described blowpit 12 is arranged on the below of described feed inlet and outlet 13.Also be provided with on described frame and control electric box 5, described control electric box 5 is controlled the keying of blower fan 6, motor 10, electric heater 3.
During work: during charging, swing roller 1, to feed inlet and outlet 13 position upward, is opened feed inlet and outlet cover plate 15, from feed inlet and outlet 13, pours rapeseed bonnet upper cover plate 15 to be dried into.While drying operation, motor 10 rotations, reduce driving rolls axle 8 by decelerator 11 by rotating speed, the rotating speed rotation by roller 7 head rolls 1 with 8 rev/mins.Lifting blade 17 with certain angle of inclination is installed on cylinder 1 inwall, and along with the rotation of cylinder 1, material is brought to top by lifting blade 17 and throws the lower loose effect of material throwing that forms.Because lifting blade 17 has certain angle of inclination, along with the rotation of cylinder 1, the logistics meeting is (air outlet 14 directions) motion along inclined direction simultaneously.Spiral feed back pipeline 16 also is housed in cylinder 1, and its hand of spiral is contrary with the incline direction of lifting blade 17, and therefore under identical drum rotating direction, both have contrary mass transport direction.Along with the rotation of cylinder 1, the logistics that feed back pipeline 16 will be deposited in air outlet 14 ends is transported to air inlet 2 ends, thereby forms Matter Transfer.While drying operation, blower fan 6 rotations produce malleation, wind is installed in electric heater 3 heating on airduct 4 during by airduct 4, and hot blast is entered after cylinder 1 after carrying out exchange heat and take away moisture by the material of shedding and discharged by air outlet 14 by air inlet 2, realizes drying materials.On air inlet 2 and air outlet 14, bearing is housed, can, not with cylinder 1 rotation, leaks for preventing logistics with screen pack is housed on air inlet 2 and air outlet 14.Open feed inlet and outlet cover plate 15 during discharging, keep cylinder 1 rotation.Along with the rotation of cylinder 1, logistics is intermittently flowed out by feed inlet and outlet 13, by packing after blowpit 12 water conservancy diversion.Because air outlet 14 ends have lost the logistics sedimentation, logistics no longer enters feed back pipeline 16, and only along with the effect of lifting blade 17 is constantly moved and finally discharged to air outlet 14 ends.Blowpit 12 both sides have been designed obliquely upward to the side plate washer extended, for reclaiming the material thrown away from feed inlet and outlet 13 with cylinder 1 rotation.
