Problems solved by technology

[0002] Mechanical seals are widely used in mechanical stirring sealing devices, but the grinding pair must be lubricated with sealing fluid. For some working conditions, when the sealing medium is not allowed to enter the reactor, the wet mechanical seal has limitations; in addition, due to the swing of the stirring shaft , the radial seal is prone to leakage

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 Shown: a stirred dry mechanical seal device for a kettle, including a bottom flange 1, a moving ring sleeve 2, a shaft sleeve 3, a seal seat body 4 and an upper static ring seat 5, a bottom flange 1, a moving ring sleeve 2 and The shaft sleeve 3 is arranged from bottom to top and the inner walls of the three are set close to the stirring shaft. The main body of the seal seat 4 and the upper static ring seat 5 are located above the bottom flange 1 and outside the moving ring sleeve 2 and the shaft sleeve 3. The shaft The top of the sleeve 3 is provided with a locking mechanism 32, and the locking mechanism 32 is fixed on the top of the shaft sleeve 3 by bolts and washers. A bearing seat 6 is provided above the upper static ring seat 5, and a first O-shaped rubber sealing ring 11 is provided at the contact surface position between...

Abstract

The invention discloses a stirring dry-type mechanical sealing device for a kettle. The stirring dry-type mechanical sealing device comprises a bottom flange (1), a moving ring sleeve (2), a shaft sleeve (3), a sealing base main body (4) and an upper static ring base (5), wherein a bearing pedestal (6) is arranged above the upper static ring base (5); deep groove ball bearings (7) for positioning are arranged between the bearing pedestal (6) and the shaft sleeve (3); an upper lip-type sealing ring (8) is arranged above the deep groove ball bearings (7); a lower lip-type sealing ring (9) is arranged below the deep groove ball bearings (7); the upper lip-type sealing ring (8) is embedded between the bearing pedestal (6) and the shaft sleeve (3); and the lower lip-type sealing ring (9) is embedded between the upper static ring base (5) and the shaft sleeve (3). The stirring dry-type mechanical sealing device has the beneficial effects that the relative displacement between the lip-type sealing rings and the shaft sleeve is avoided through the radial sealing of the lip-type sealing rings and the positioning effect of the double deep groove ball bearings, and a sealing effect is achieved; and the arrangement of a compensation O-shaped rubber sealing ring ensures that the swinging of a stirring shaft does not affect the positional relationship between the lip-type sealing rings and the shaft sleeve.

Description

technical field [0001] The invention relates to the technical field of stirring equipment, in particular to a stirring dry mechanical seal device for kettles which adopts a double-lip radial seal and can compensate for the deflection of the stirring shaft. Background technique [0002] Mechanical seals are widely used in mechanical stirring sealing devices, but the grinding pair must be lubricated with sealing fluid. For some working conditions, when the sealing medium is not allowed to enter the reactor, the wet mechanical seal has limitations; in addition, due to the swing of the stirring shaft , The radial seal is prone to leakage. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior art, and provide a stirring dry mechanical seal device for kettles which adopts a double-lip radial seal and can compensate for the deflection of the stirring shaft. [0004] The purpose of the present invention is solved by ...
