For achieving the above object, technical solution adopted in the utility model is:
This installs overall sealing thinking: adopt " liquid lock " principle, utilize pressure a little more than the distilled water of pressure medium as sealing fluid, ensure that processing medium realizes " zero leakage ".
This device comprises axle sleeve, and axle sleeve is socketed in rotating shaft; Axle sleeve socket side medium mechanical seal pair, flange, side medium spring seat, cavity, end cap, atmospheric side mechanical seal pair, driving ring; Described side medium mechanical seal pair comprises side medium rotating ring and side medium stationary ring, side medium moving ring sleeve is connected in axle sleeve, side medium stationary ring overcoat acting flange, flange connecting media side spring seat, installs side medium Compress Spring in side medium spring seat, cavity is connected with side medium spring seat, side medium spring seat arranges sealingfluid inlet, seal fluid outlet is set on cavity, and end cap is connected with cavity, and end cap connects positioning block; Atmospheric side mechanical seal secondary case is connected in cavity, and atmospheric side mechanical seal pair comprises atmospheric side stationary ring and atmospheric side rotating ring, and atmospheric side rotating ring connects end cap, and atmospheric side Compress Spring is installed in cavity, and driving ring is fixedly connected with axle sleeve with rotating shaft.
Preferably, between described rotating shaft and axle sleeve, between side medium rotating ring and axle sleeve, between side medium stationary ring and flange, between flange and side medium spring seat, between side medium spring seat and cavity, between cavity and end cap, between atmospheric side rotating ring and axle sleeve, be equipped with seal arrangement between atmospheric side stationary ring and end cap, on the attachment face of flange, be also provided with seal arrangement.
Preferably, described driving ring is fixed on rotating shaft and axle sleeve by Cock screw.
Preferably, described axle sleeve, flange all do chamfering or fillet processing.
The beneficial effect that this rake type dryer mechanical seal device produces is: this device adopts " liquid lock " principle, utilize pressure a little more than the distilled water of pressure medium as sealing fluid, ensure processing medium realization " zero leakage ", effectively realize the sealing to rake type dryer, greatly reduce the contaminated possibility of material, reduced the loss therefore producing; In device, there is a turning point with the structural member of medium contact is all, be all designed with suitable rounding or chamfering, can effectively avoid the dead angle of sterilizing; This device is realized production domesticization, cheap, efficiently solves Sealing import and has the problems such as price is high, the delivery cycle is long, once sealing is broken down, can replace rapidly, and the long-time problem stopping production can not occur.
