Description
Technical field
The utility model belongs to slurries pumping equipment technical field, is specifically related to the high viscosity slurry gear pump mechanical seal device of cigarette with diacetate fiber slurry preparation operation.
Background technique
Cigarette is external the imported technology with the diacetate fiber production technology, master operation is the circulating filtration and the conveying of diacetate fiber slurries, because the diacetate fiber slurries have viscosity big, contain inflammable and explosive acetone solvent in the slurries, slurries are carried and are adopted the high-pressure delivery mode in the prior art, mainly realize by gear pump.Gear pump can produce impulse oscillation when operation, its mechanical seal is prone to leakage under high pressure and vibration environment, and the acetone volatilization can appear in the slurries of leakage, not only has certain potential safety hazard, and has caused the waste of raw materials; Both pollute environment, increased personnel labor and workload again.For this reason, the design people has developed a kind of suitable high viscosity slurry gear pump mechanical seal device at the deficiencies in the prior art, has solved the problem that the sealing of prior art gear pump is easily revealed well, evidence, and effect is good.
The model utility content
The purpose of this utility model is to provide a kind of working stability reliable, can prevent effectively that slurries from leaking, and to ensureing production safety, avoids wastage of material, keeps clean environment, significantly reduces the mechanical seal device of the high viscosity slurry gear pump of staff labor intensity.
The purpose of this utility model is achieved in that and comprises stationary ring, rotating ring, retaining ring, stationary ring and stationary seat transition fit, and prevent that by stop pin stationary ring from rotating, and has bosh on the stationary seat; The fastening rotating ring of moving ring sleeve front end, bellows two ends constitute moving ring assembly with moving ring sleeve, rotating ring guide sleeve Joint respectively, and moving ring assembly is fixed on the rotatingshaft by retaining ring.
The utility model adopts the rotating ring mechanical sealing technology, makes the break-in face of rotating ring and stationary ring can keep automatically fitting mutually closely all the time, realizes the dynamic compensation sealing.It is inner and be frozen into lump to adopt the flexible graphite packing ring to make slurries can not enter moving ring assembly in the seal groove of guide sleeve, guarantees that bellows is capable of expansion and contraction.The utility model has overcome the influence that gear pump easily produces impulse oscillation, solve the leakage of slurries gear pump under high pressure and vibration preferably, avoided the waste of raw materials, ensured production safety, reduce personnel labor, kept clean environment that positive effect is arranged.The rotating ring of dipping polyflon material and stationary ring can high temperature not occur because of excessively rubbing, and have explosion prevention function, have improved the safety in operation of gear pump in pumping diacetate fiber slurries process.
