Description
Technical field
The utility model relates to a kind of sealing device, particularly bottom type rotating shaft of stirrer sealing device.
Background technology
Mixer is a plant equipment the most commonly used, it is few that the bottom type mixer has a bottom deposit, mix, advantages such as power consumption is few obtain wider application, but in the fluid that stirs, not only may have solid particle, also may present stronger acidity or alkaline, the countershaft encapsulant select for use and the design of hermetically-sealed construction brings bigger problem, poor sealing performance not only can increase the maintenance cost of breakdown rate and equipment, reduce equipment life, the leakage that poor sealing performance causes also can be corroded the parts and the contaminated environment of agitator, directly influences the use of agitator.
Summary of the invention
The purpose of this utility model provides a kind of bottom type rotating shaft of stirrer sealing device, adopt mechanical seal, effect by spring force makes two sealing surfaces of rotating shaft keep in touch all the time, and do relative motion, avoid the generation of leaking, when seal face weares and teares, rotating ring together with the rotating ring sealing ring under the promotion of spring, produce minute movement vertically, play certain compensating action.Reach the reliability that improves the rotating shaft of stirrer sealing, prevent to leak the purpose that increases the service life.
The utility model realizes that by following technical scheme it comprises rotating shaft 1, end cap 2, Che Shi combination sealing 3, end cap seal circle 4, self-aligning bearing 5, bearing spider 6, spring base 7, spring 8, rotating ring 9, rotating ring sealing ring 10, stationary ring 11, stationary ring sealing ring 12, stop pin 13, deep groove ball bearing 14, bearing spider sealing ring 15, installing plate 16, agitator base plate 17.Rotating shaft 1 is supported and is fixed on the bearing spider 6 by self-aligning bearing 5 and deep groove ball bearing 14, bearing spider 6 is fixed by bolts on the installing plate 16, installing plate 16 is welded on the agitator base plate 17, end cap 2 is fixed by bolts on the bearing spider 6, spring base 7 usefulness trip bolts are fixed in the rotating shaft 1, stationary ring 11 usefulness stop pins 13 are fixed on the bearing spider 6, rotating ring 9 contacts by spring 8 supportings and with 11 of stationary rings, stop pin 13 is fixed on the static bearing spider 6, a pair of Che Shi combination sealing 3 is enclosed within respectively in the seal groove of end cap 2 and agitator base plate 17, end cap seal circle 4, rotating ring sealing ring 10, stationary ring sealing ring 12, bearing spider sealing ring 15 is enclosed within respectively in the corresponding seal groove.
When rotating shaft 1 rotation, by holding screw and 9 rotations of spring 8 driven rotary rings, stop pin 13 is fixed on the static bearing spider 6, prevent that stationary ring 11 from rotating, when seal face weares and teares, rotating ring 9 together with rotating ring sealing ring 10 under the promotion of spring 8, produce minute movement vertically, reach certain compensation ability, combination sealing 3 is acid proof Che Shi sealing, H type slip ring and an O shape rubber ring by the band oil storage tank of polytetrafluoroethylmaterial material combine, and can realize the sealing to high-speed rotating shaft, prevent to leak.
The advantage that the utility model had:
1) adopts mechanical seal, two sealing surfaces of rotating shaft are kept in touch, and do relative motion, avoid the generation of leaking;
2) when seal face weares and teares, rotating ring under the promotion of spring, produces minute movement together with the rotating ring sealing ring vertically, reaches certain compensating action;
3) adopt acid proof Che Shi combination sealing, the H type slip ring of its oil storage tank can be stored fluid and keep the lubricated of countershaft;
4) mechanical seal combines in combination sealing, improves the reliability of rotating shaft sealing, reduces and leaks, and prolongs stirrer life.
