Abstract
The utility model discloses a mechanical sealing device for a slurry reaction kettle agitator. The mechanical sealing device comprises a rotating ring component, a stationary ring component, a buffering and compensating mechanism, and an auxiliary sealing and transmission mechanism, and is characterized in that O-shaped rings and supporting rings are arranged between lower rotating ring seats and lower rotating rings, and contact end faces between the lower rotating ring seats and the O-shaped rings are horizontal end faces. The mechanical sealing device for the slurry reaction kettle agitator can adapt to the rapid change of differential pressure of a reactor and sealing liquid, so that excellent sealing performance is ensured under the conditions of high temperature and high pressure and pressure oscillation of public utilities, and a phenomenon that the sealing liquid leaks is avoided; and moreover, the product quality is improved, the security risk is reduced, and the life cycle of the device is prolonged.
Description
Technical field
The utility model relates to a kind of mechanical seal device, relates in particular to a kind of slurry reaction still stirrer and uses mechanical seal device.
Background technique
In fields such as petrochemical industry, rubber, papermaking, pharmacy, the reaction mass in the reaction kettle fully stirs through stirrer under specific temperature, pressure, catalytic condition, reaches the product yield of setting.But because material has high temperature, high pressure, inflammable, explosive, easy characteristic of leaking in the petroleum chemical industry,, guarantee production safety, must between reactor and stirring shaft, mechanical seal device be installed for preventing material from leakage.As shown in Figure 1, existing slurry reaction still stirrer comprises moving ring assembly, static components, buffering compensation mechanism, auxiliary seal and driving mechanism with mechanical seal device.Moving ring assembly comprises rotating ring, following rotating ring 13; Static components comprises stationary ring, following stationary ring 9, following stationary ring ABAP Adapter 12 and lower flange 10; Compensation damping mechanism assembly comprises rotating seat and following rotating seat 16, spring seat 2, spring 3, driving pin; The auxiliary seal assembly comprises serial auxiliary seal ring; Geartrain systems comprises axle sleeve, drive pin, positioning ring 1, key etc.Existing slurry reaction still stirrer is provided with three road V-arrangement ptfe rings 4 and a support ring 5 with in the mechanical seal device between following rotating seat 16 and the following rotating ring 13, and descends rotating seat 16 to contact end face with V-arrangement ptfe ring 4 and be arranged to the V-type end face; Be provided with three road V-arrangement ptfe rings 6 and a support ring 7 between following stationary ring ABAP Adapter 12 and the lower flange 10, and descend stationary ring ABAP Adapter 12 to contact end face and be arranged to the V-type end face with V-arrangement ptfe ring 6.Because the elasticity of V-arrangement ptfe ring is bad, tracing ability is poor, and compensation ability is low; So at HTHP, when fluctuation appears in Utilities pressure, can't guarantee sealability, leakage phenomenon occur through regular meeting; Not only influence the quality of product of enterprise; Caused economic loss to enterprise, and produced huge potential safety hazard, safety and production in serious threat.
The model utility content
The purpose of the utility model provides a kind of slurry reaction still stirrer and uses mechanical seal device, can improve sealability, avoids product under HTHP, Utilities pressure surge situation, leakage phenomenon to take place.
The utility model adopts following technical proposals:
A kind of slurry reaction still stirrer is used mechanical seal device; Comprise moving ring assembly, static components, buffering compensation mechanism, auxiliary seal and driving mechanism; Wherein moving ring assembly comprises rotating ring, following rotating ring, and static components comprises stationary ring, following stationary ring, following stationary ring ABAP Adapter and lower flange, and compensation damping mechanism assembly comprises rotating seat and following rotating seat; Be provided with O shape ring and support ring between said rotating seat down and the following rotating ring, following rotating seat and O shape loop contacts end face are set to horizontal end face.
Be provided with O shape ring and support ring between described stationary ring ABAP Adapter down and the lower flange, following stationary ring ABAP Adapter and O shape loop contacts end face are horizontal end face.
The utility model replaces with O shape ring through having slurry reaction still stirrer now with three road V-arrangement ptfe rings in the mechanical seal device; End face with O shape loop contacts is set to flat end face simultaneously, according to reactor internal pressure, sealed fluid pressure, sealing surface material, end face diameter and fluid viscosity, calculates seal face load factor K value and spring force value; Through setting the elastic force value of suitable spring members; Make the rapid change of further adaptive response device of the utility model and sealed hydraulic difference, make product under HTHP, Utilities pressure surge situation, guarantee excellent sealing performance, can adapt to 90 ~ 350 ℃, the sealed environment of 2 ~ 30MPa pressure; Avoid taking place leakage phenomenon; Improve the quality of products, reduce potential safety hazard, prolong the equipment life cycle.
