The specific embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments.

As shown in Figure 1 and Figure 2, in the present embodiment, described high performance dehydrating drier comprises: frame 1, frame 1 is provided with by upper and lower two semicircle

cylindrical shells

31 and 32 synthetic cylindrical shells, upper and lower semicircle cylindrical shell 31 and a side of 32 are hinged by hinge 312, drive oil cylinder 311 and be fixedly mounted on the frame 1, the piston rod 313 that drives oil cylinder 311 flexibly connects with the actuating arm 314 that is fixed on the semicircle cylindrical shell 31, drives oil cylinder 311 by control and can open or close up semicircle cylindrical shell 31; Housing bottom is provided with delivery port 33, main shaft 4 is arranged in the housing by pair of bearings 5, one end of main shaft 4 is provided with follower 71 after stretching out housing, frame 1 is provided with motor 70, the output shaft of motor 70 is provided with driving wheel 73, is provided with driving-belt 72 between driving wheel 73 and the follower 71; In semicircle cylindrical shell 31 both upper ends thereof, be respectively arranged with charging aperture 34 and discharging opening 35 along columnar tangential direction, referring to Fig. 3, Fig. 4, shown in Figure 5, also being set with cross section in housing is octagonal filter screen---in the present embodiment, filter screen is synthesized by upper and lower two

parts filter screen

61 and 62, and last half filter screen 61 and following half filter screen 62 are bolted to connection; Referring to Fig. 1, Fig. 6, Fig. 8, shown in Figure 9, being set with some blade seats 22 on the main shaft 4---the quantity of blade seat 22 can be determined according to the length and the real work needs of main shaft 4 during in actual fabrication, along the circumferential direction evenly be provided with three blades 21 on each blade seat 22, blade on adjacent two blade seats---interlaced and along the circumferential direction evenly arrange as 211 and 212: i.e. blade---is as 211 and 212, or 212 and 213 60 degree that along the circumferential direction stagger mutually, and the blade on the odd bits blade seat is arranged to about 0.5 degree of the inclined to one side successively mistake of same direction, blade on the even bit blade seat is also arranged to about 0.5 degree of the inclined to one side successively mistake of same direction, as: the

blade

211 and 213 that is in odd bits, about 0.5 degree of inclined to one side successively mistake between 213 and 215, be in the

blade

212 and 214 of even bit, about 0.5 degree of inclined to one side successively mistake between 214 and 216, like this, referring to shown in Figure 7, be in the blade of first odd bits and be between the blade of terminal odd bits just angle C of the inclined to one side mistake of accumulative total, also add up angle of inclined to one side mistake between the blade that is in first even bit and the blade that is in terminal even bit---if identical then this angle with even bit of odd bits also is C, that is to say, just constitute a helix to the blade of terminal odd bits successively from the blade of first odd bits, equally, also constitute a helix to the blade of terminal even bit successively from the blade of first even bit.In the present embodiment, the end face of each blade and the included angle B between the main-shaft axis are approximately 8 degree---referring to shown in Figure 9, and when each blade during in the extreme higher position its lateral surface with pass through included angle A between the vertical plane of this lateral surface upper sideline and also be approximately 8 and spend---referring to shown in Figure 8.

The operation principle of the high performance dehydrating drier of said structure is: pending material is sent into from charging aperture 34, starter motor 1 makes main shaft 4 rotation at a high speed, main shaft 4 drives all blade 21 rotations at a high speed, under the interaction of blade that rotates at a high speed and octagonal filter screen, material carries out random encounters in filter screen, provide thermal source by friction generates heat simultaneously; The blade of high speed rotation also carries out moment compression release heat energy to the gas in the housing material is assisted heating, in housing, form simultaneously by charging aperture 34 to discharging opening 35 airflow flowing, and utilize the gas of the compression air-flow that produces that expands that material is sent from discharging opening 35.As seen, the drying machine of said structure can carry out online wink-dry, reproduce the above-mentioned drying machine of use in the production line in the whole piece plastics recovery, can make production line compact conformation, craft science, energy consumption is low, output is big, noise is low, the time that dehydrates is short, effective, material dewatering rate after dehydrating processing can be directly used in the processing of next procedure up to more than 95%.
