Paddle-dryer is that one kind sets stirring slurry in device interior, makes wet stock under the agitation of blade, is carried with heat
Body and hot surface fully contact, and so as to reach the stirring at low speed drier of drying purpose, structure type is generally horizontal, twin shaft
Or four axle.The charge door of drying machine is quantitatively continuously introduced into by feed screw by dry material, material enters device behind, leads to
Crossing the rotation of blade makes material upset, stirring, constantly updates heating interface, contacts, be sufficiently heated with device body and blade, make thing
The contained surface moisture evaporation of material.Meanwhile material conveys with the helical trajectory that is rotated into of paddle shaft to discharging opening direction, is conveying
In continue to stir, the moisture for making to ooze out in sludge continues to evaporate.Finally, the qualified products of uniform drying are discharged by discharging opening.
In the paddle-dryer of routine, by bearing in bearing housing, bearing housing is fixedly arranged at the both ends of paddle shaft
On body.As shown in figure 1, the shaft shoulder of paddle shaft is bonded with the inner side of bearing inner race, and position of the bearing outer ring in bearing housing
Fixed, the bearing at paddle shaft both ends is so to be fixedly mounted.By long-term experiment, it is found by the applicant that this fixed form is held
Easily go wrong, due to effect of expanding with heat and contract with cold, when paddle shaft, which is heated, to be expanded to both ends, the shaft shoulder of paddle shaft can be with dynamic bearing
Circle moves laterally, and when the displacement of bearing inner race exceeds the adjustable extent of bearing, bearing will damage.Also, due to
For paddle-dryer in working condition and during off working state, the temperature difference of paddle shaft is very big, i.e., paddle shaft at work,
It can occur largely to expand, in addition the changing factor of weather temperature so that cause bearing because paddle shaft expands with heat and contract with cold
The possibility of damage greatly increases.
Further, since larger distance between blade tip and body inwall be present, as shown in figure 3, then organism bottom accumulates
The material stayed then can not effectively be stirred and dried.
