Abstract
The invention discloses a sealing device of a reaction kettle. The sealing device comprises a stationary ring, a stationary ring holder for fixedly mounting the stationary ring on a reaction kettle cover, a movable ring which sleeves a stirring shaft and moves along with the stirring shaft, a movable ring holder fixedly mounted on the movable ring, and a spring arranged between the movable ring and the movable ring holder; the lower end face of the movable ring is propped against the upper end face of the stationary ring; a cone is integrally formed on the movable ring; a taper hole matched with the cone is formed in the movable ring holder; a vertical groove is formed in the movable ring. Due to the matching of the cone and the taper hole in use, a movable sealing ring is clamped between the movable ring and the stirring shaft, and therefore, leakage is avoided and the sealing effect is improved.

The technical problem to be solved in the present invention is to provide a kind of good sealing effect, is difficult for the seal arrangement of the reactor of generation leakage.
(2) technological scheme
For solving the problems of the technologies described above, the invention provides a kind of seal arrangement of reactor, it comprises stationary ring, stationary ring is fixedly mounted on to the stationary ring fixed base on reactor kettle cover, be sleeved on stirring shaft rotating ring outer and that move with stirring shaft, be fixedly mounted on the rotating ring fixed base on rotating ring, and be arranged on the spring between rotating ring and rotating ring fixed base; The lower end surface of rotating ring is resisted against the upper-end surface of stationary ring, and one-body molded on rotating ring have a centrum, offers the taper hole coordinating with centrum on rotating ring fixed base, is provided with vertical slot on rotating ring.
Wherein, between rotating ring and stirring shaft, be provided with dynamic seal ring.
Wherein, on kettle cover, be provided with for locating the positioning boss of stationary ring.
Wherein, between stationary ring fixed base and kettle cover, be provided with sealing gasket.
Wherein, between stationary ring and stationary ring fixed base, be provided with static sealing ring.
Wherein, on rotating ring, be provided with the first locating column for retaining spring.
Wherein, on rotating ring fixed base, be provided with the second locating column for retaining spring.
(3) beneficial effect
Compared with prior art, being used in conjunction with of centrum of the present invention and taper hole, is clamped between rotating ring and stirring shaft dynamic seal ring, avoids leaking, and has improved sealing effect.
