Description

Kettle side entering type mechanical seal
Technical field
The utility model is related to kettle side entering type mechanical seal, on the kettle wall of stirred tank side-lower, for preventing Stirred tank internal flow is along the axial rotary kettle external leakage through stirred tank, and it belongs to Double End integrated mechanical sealing.
Background technology
Mechanical seal is also known as end face seal, and existing more than 100 years usage history, is rotary shaft dynamic sealing, conventional bag Include single mechanical end face seal and double mechanical seal.Most agitating shafts head into kettle from kettle, so inputting type vesselseals It is more common.But some large-scale stirred tanks need side stir machine, kettle side entering type mechanical seal is at this moment needed.Kettle is entered with side Formula mechanical seal has kettle wall vibrations when working fluid directly touches machinery containing solid particle in force unbalance and kettle in addition The problem of sealing friction pair, therefore it is easier the influence life-span that wrecks.Inventor once invented the " single end face with elastic sealing ring Mechanical seal and double mechanical seal ZL201410079791.1 ", the beneficial effect of the invention are the floatings of floating drag ring Effect is good, and excellent sealing, and parts manufacture difficulty can also be kept in the case where the bounce or swing of rotary shaft are larger Small cost reduction, while reducing mechanical seal to facilitate design and installation also to save material.If the improvement of the invention Technology is applied to kettle side entering type mechanical seal, in addition it is also necessary to do a little improvement, such as kettle is included with side entering type mechanical seal contact kettle Improvement, Yi Jixiang in terms of improvement, the bounce of control agitating shaft or the swing of the structure design at solid particle fluid media (medium) position The correspondence adjustment of structure is closed, so as to improve the service life of kettle side entering type mechanical seal.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of kettle side entering type mechanical seal, and its kettle interior side contacts contains The position of solid particle fluid media (medium) is to be straight without depression smooth surface, and no alluvial is blocked, and agitating shaft vibration deformation is small, rotating ring and stationary ring Stress equalization, so as to improve service life.
In order to solve the above technical problems, a kind of kettle side entering type mechanical seal is invented, including for being sealingly mounted to kettle side Mounting flange, drive rotary part on wall rotate and sealed the axle sleeve being fixed on agitating shaft with agitating shaft and form double Two pairs of friction pairs being made up of rotating ring and stationary ring of end surface mechanical sealing, two pairs of friction pairs and axle sleeve, two rotating seats, Method for Installation Blue and cylinder surrounds hydraulic cavities, and spring keeps abrasive end face sealing to the stationary ring pressure of floating drag ring, and other of hydraulic cavities are close By elastic sealing ring pressure bearing and seal at envelope, elastic sealing ring and rotating seat gluing, sealing rotating ring inner cylinder face, sealing ring and cylinder Seal filler ring or flange seal filler ring gluing, sealing stationary ring external cylindrical surface.Hydraulic circulation fluid apertures is designed with cylinder to import Hydraulic pressure cavity fluid pressure is all the time slightly larger than pressure in kettle so that elastic sealing ring is in export circulation fluid guarantee work Effective sealing state, while to rotating ring and stationary ring abrasive end face cooling and lubricating.Design the friction that rotating ring constitutes friction pair with stationary ring End face internal diameter and outside dimension is equal and external diameter is not less than rotating seat external diameter, adds there is no traditional rotating seat to the parcel of rotating ring It is strong and be used as the cylindrical ledge structure of the stationary ring of floating drag ring, the friction of such kettle interior side contacts fluid media (medium) containing solid particle End face area for it is straight without depression smooth surface, can avoid fluid media (medium) containing solid particle deposit be blocked near abrasive end face cause it is close Envelope failure.In order that rotating ring and stationary ring stress equalization, elastic sealing ring is axially disposed within close to abrasive end face along rotating ring during design Position, elastic sealing ring is axially also disposed at the position close to abrasive end face along stationary ring.In order to reduce agitating shaft vibration deformation Destruction to mechanical seal, kettle be also configured with side entering type mechanical seal agitating shaft spring bearing by bearing block and The cylinder and mounting flange for being secured to connection are positioned on the wall of stirred tank side.It is preferred that rotating ring uses same hard friction with stationary ring Ring material and external diameter are equal to rotating seat external diameter, so manufacture and design simple and keep friction pair abrasion to coordinate consistent.
The beneficial effects of the utility model are that the position of kettle interior side contacts fluid media (medium) containing solid particle is straight without depression Smooth surface, no alluvial is blocked, and agitating shaft vibration deformation is small, rotating ring and stationary ring stress equalization, so as to improve service life.

Embodiment
The side entering type mechanical seal of kettle shown in Fig. 1, is sealingly mounted on the wall of kettle side by mounting flange 11, adjustment positioning After good, axle sleeve 5 is fixed on agitating shaft using axle sleeve fixing device 1, then releasing packaging fastener 2 makes kettle side entering type machinery Sealing is in stand-by state.Axle sleeve 5 is that sealing is fixed on agitating shaft.Two pairs of friction pairs being made up of rotating ring 8 and stationary ring 9 with Axle sleeve 5, two rotating seats 7, mounting flange 11 and cylinder 10 surround hydraulic cavities 12, and the stationary ring 9 of 13 pairs of floating drag rings of spring is applied Pressure keeps abrasive end face sealing, elastic sealing ring 14 and the inner cylinder face of 7 gluing, sealing rotating ring of rotating seat 8, sealing ring 14 and cylinder Seal filler ring 102 or the external cylindrical surface of 111 gluing, sealing stationary ring of flange seal filler ring 9.Hydraulic circulation fluid apertures is designed with cylinder 10 101 to import and export in circulation fluid guarantee work the fluid pressure of hydraulic cavities 12 all the time slightly larger than pressure in kettle so that bullet Property sealing ring 14 be in effective sealing state.Rotating ring 8 and stationary ring 9 are carborundum hard drag ring material, abrasive end face internal diameter It is equal with outside dimension and equal to the external diameter of rotating seat 7.Elastic sealing ring 14 is axially disposed within the position close to abrasive end face along rotating ring 8 Put, elastic sealing ring 14 is axially also disposed at the position close to abrasive end face along stationary ring 9.In kettle with side entering type mechanical seal It is configured with agitating shaft spring bearing 3 and stirred tank is positioned at by bearing block and the cylinder 10 and mounting flange 11 that are secured to connect On the wall of side, the inner side of bearing block diagram to the right is used to exclude the circulation fluid that mechanical seal is leaked out, bearing block provided with leakage chamber 6 It is provided with bearing oil filler point 4.
