Abstract
The utility model discloses a kind of axle sealing structure of machine mixing device, comprise and to be arranged on mixing plant for end cap, the sealed case be arranged on this end cap, the stirring shaft be arranged in sealing case of fixing described shaft sealer, to be arranged on the filler between described sealed case and this stirring shaft and to be arranged on described sealed case upper end for compressing the gland of described filler, it is characterized in that: on described sealed case, be provided with lubricating cup, oil ring is provided with in described sealed case, described filler arranges the two ends of this oil ring, and described oil ring communicates with described lubricating cup.Oiling agent in operation process in filler constantly consumes, and be arranged on the middle oil ring of filler to automatic oiling in filler, in lubricating cup, oil also can refuel from trend oil ring simultaneously, keeps lubrication.
Description
Technical field
The utility model relates to a kind of axle sealing structure, particularly a kind of axle sealing structure being applicable to machine mixing device.
Background technique
The shaft seal of mechanically stirred reactor seals mainly packing seal and mechanical seal, and the effect of shaft sealing avoids medium to be infiltrated in stirred vessel from stirred vessel internal leakage or foreign matter by rotating shaft.Wherein, packing seal structure is simple, easy to manufacture, is not applicable to non-aggressive and weak erosive medium, seal request high and allow the mixing plant of periodic maintenance.Containing oiling agent in filler, while radial compacting force is produced to stirring shaft, form the liquid film that one deck is very thin, on the one hand stirring shaft is lubricated, stop the effusion of equipment inner fluid or the infiltration of external fluid on the other hand, reach the object of sealing.But the oiling agent in filler can on-stream continuous consumption, when oiling agent consumes, then can accelerate the wearing and tearing between axle and filler, make seal failure.
Model utility content
The technical problems to be solved in the utility model is the present situation for prior art, provides the axle sealing structure that a kind of good sealing effect, structure are simple, automatically can increase the machine mixing device of lubricant oil for the filler in shaft sealing.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of axle sealing structure of machine mixing device, comprise the end cap be arranged on for fixing described shaft sealer on mixing plant, be arranged on the sealed case on this end cap, be arranged on the stirring shaft in sealing case, be arranged on the filler between described sealed case and this stirring shaft and be arranged on described sealed case upper end for compressing the gland of described filler, it is characterized in that: on described sealed case, be provided with lubricating cup, oil ring is provided with in described sealed case, described filler arranges the two ends of this oil ring, and described oil ring communicates with described lubricating cup.
As improvement, the outer circumferential face of described sealed case is provided with lower protruding edge, the outer circumferential face of described gland is provided with upper flange, this upper flange and this lower protruding edge have tapped hole, described sealed case is connected by stud bolt with described gland, be convenient to the impacting force adjusting gland in operation, be convenient to regularly replace filler.
Improve again, described end cap has groove, sealing gasket is provided with in this groove, described sealed case is pressed on described sealing gasket, in described sealed case, be also provided with the base ring for compressing described filler, described base ring, described sealed case, described sealing gasket and described end cap form a seal space, and sealing space defines the second defence line of sealing, even if when the seal failure in sealed case, sealing oil is also not easily thrown out of.
Compared with prior art, owing to the utility model has the advantage of: owing to containing oiling agent in filler, while radial compacting force is produced to stirring shaft, form the liquid film that one deck is very thin, on the one hand stirring shaft is lubricated, stop the effusion of equipment inner fluid or the infiltration of external fluid on the other hand, reach the object of sealing, oiling agent in operation process in filler constantly consumes, be arranged on the middle oil ring of filler to automatic oiling in filler, in lubricating cup, oil also can refuel from trend oil ring simultaneously, keep lubrication, prevent oiling agent in filler after loss, accelerate the wearing and tearing between axle and filler, make seal failure, it also avoid the troublesome operation that manual teardown shaft sealer refuels to filler simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the axle sealing structure of machine mixing device in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the axle sealing structure of the machine mixing device in this enforcement, comprises end cap 8, sealed case 4, stirring shaft 3, filler 5, gland 2, lubricating cup 10, oil ring 9, stud bolt 1, sealing gasket 7 and base ring 6 etc.
Wherein, end cap 8 is arranged on mixing plant for stationary axle seal arrangement, sealed case 4 is arranged on this end cap 8, stirring shaft 3 is arranged in sealing case 4, gland 2 is arranged on sealed case 4 upper end for compressing described filler 5, sealed case 4 is provided with lubricating cup 10, is provided with oil ring 9 in sealed case 4, the two ends being positioned at oil ring 9 between sealed case 4 and this stirring shaft 3 are provided with filler 5, and oil ring 9 communicates with lubricating cup 10.
In addition, lower protruding edge 41 is provided with at the outer circumferential face of sealed case 4, the outer circumferential face of gland 2 is provided with upper flange 21, this upper flange 21 and this lower protruding edge 41 have tapped hole, sealed case 4 is connected by stud bolt 1 with gland 2, be convenient to the impacting force adjusting gland 2 in operation, be convenient to regularly replace filler 5.
In addition, end cap 8 has groove 81, sealing gasket 7 is provided with in this groove 81, sealed case 4 is pressed on sealing gasket 7, is also provided with the base ring 6 for compressing filler 5, wherein in sealed case 4, base ring 6, sealed case 4, sealing gasket 7 and end cap 8 form a seal space, sealing space defines the second defence line of sealing, even if when the seal failure in sealed case 4, sealing oil is also not easily thrown out of.
