The advantage: be equipped with flexible sealing spare, solved the dust problem of leaking that rotation axis off -centre leads to packing and extrudees wearing and tearing and arouse, be equipped with the rigidity skeleton inside flexible sealing spare, improved seal assembly's sealed effect and life, inside packing of recess on the axle sleeve inner wall has lubricating grease, both can play lubrication action, can block again that the dust extrudees along the axial outward.
Description
Technical field:
The utility model relates to a kind of seal arrangement, relates in particular to a kind of fine material mixer sealing device for rotary shaft.
Background technique
Fine material mixer generally comprises casing, driven unit, stirring shaft, black box etc., running shaft and casing binding site are provided with stuffing box, packing is loaded in stuffing box, outside gland is by filler press seal, during owing to stirring the vibration of axle and circular runout larger, the gap of filler and axle is circumferentially in crescent shape, and interstitial site changes in periodic with the rotation of axle, and the tight power of packing and axle is uneven at circumferencial direction; Along with the prolongation of mixing time, packing is stressed, wearing and tearing nonuniformity increases gradually, and in casing, thin ash scurries into bearing along the clearance leakage between running shaft and packing, easily causes bearing lubrication to damage, and also pollutes production environment simultaneously.
Model utility content:
The purpose of this utility model is to provide that a kind of structure is simple, the fine material mixer sealing device for rotary shaft of good airproof performance.
The utility model is implemented by following technological scheme: a kind of fine material mixer sealing device for rotary shaft, it comprises stuffing box, flexible seals and annular gland, axis hole is provided with in the middle part of at the bottom of described stuffing box box, be filled with stuffing box packing in described stuffing box inside, described stuffing box box top extends radially outward and is provided with card edge; Described flexible seals is provided with along outside split at described card; Described flexible seals is made up of seal ring and axle sleeve, and described seal ring and described axle sleeve are formed in one structure, are provided with the steel frame identical with described flexible seals global shape in described flexible seals; Described seal ring one end and described card, along movable contact, are fixed with described axle sleeve at the described seal ring the other end; The axis of described seal ring and described axle sleeve all with the axis of described axis hole point-blank; The internal diameter of described seal ring is identical with the internal diameter of described axle sleeve, and is less than the diameter of described axis hole; Described sleeve lining is evenly provided with the groove of maze type, in described groove, is filled with lubricating grease; Annular gland is provided with, described annular gland and described seal ring movable contact in described axle sleeve outer cover; The external diameter of described seal ring is less than the external diameter on described annular gland and described card edge, the described annular gland of described seal ring periphery and described card are provided with at least three attachment holes along upper correspondence respectively, and described annular gland and described card edge are by being connected through the bolt of the described attachment hole of correspondence.
Two clamp rings are at least arranged with in described axle sleeve outside.
Advantage of the present utility model: be provided with flexible seals, solves rotating shaft eccentric and causes filler extrusion abrasion and the dust leakage problem caused; Be provided with rigid backbone in flexible seals inside, improve sealing effect and the working life of black box; Inside grooves on sleeve lining is filled with lubricating grease, both can play lubrication, can stop again dust outer extruding vertically.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present utility model.
Stuffing box 1, flexible seals 2, annular gland 3, axis hole 4, block along 5, seal ring 6, axle sleeve 7, groove 8, lubricating grease 9, bolt 10, stuffing box packing 11, rigid backbone 12, clamp ring 13, attachment hole 14, running shaft 15, stirrer housing 16.
Embodiment:
As shown in Figure 1, a kind of fine material mixer sealing device for rotary shaft, it comprises stuffing box 1, flexible seals 2 and annular gland 3, is provided with axis hole 4 in the middle part of at the bottom of stuffing box 1 box, and stuffing box 1 is set on running shaft 15 by axis hole 4; Be filled with stuffing box packing 11 in stuffing box 1 inside, stuffing box packing 11 can stop the dust that major part outwards extrudes along running shaft 15; Stuffing box 1 box top extends radially outward and is provided with card along 5; Card along 5 outside split be provided with flexible seals 2; Flexible seals 2 is made up of seal ring 6 and axle sleeve 7, seal ring 6 and axle sleeve 7 are formed in one structure, in flexible seals 2, be provided with the rigid backbone 12 identical with flexible seals 2 global shape, rigid backbone 12 can improve the rigidity of flexible seals 2, reduces distortion; Stuffing box packing 11, along 5 movable contacts, is sealed in stuffing box 1 inner by seal ring 6 one end and card; Axle sleeve 7 is fixed with at seal ring 6 the other end; The axis of seal ring 6 and axle sleeve 7 and the axis of axis hole 4 are point-blank; The internal diameter of seal ring 6 is identical with the internal diameter of axle sleeve 7, and is less than the diameter of axis hole 4; Axle sleeve 7 inwall is evenly provided with the groove 8 of maze type, is filled with lubricating grease 9 in groove 8, lubricating grease 9 both can play lubricating and wear-resisting effect, can stop again string ash further; Annular gland 3 is provided with, annular gland 3 and seal ring 6 movable contact in axle sleeve 7 outer cover; The external diameter of seal ring 6 is less than annular gland 3 and the card external diameter along 5, the annular gland 3 of seal ring 6 periphery and card along on 5 respectively correspondence be provided with four attachment holes 14, annular gland 3 and card are connected along 5 bolts 10 passed through through corresponding attachment hole 14; Be provided with two clamp rings 13 in axle sleeve 7 outer cover, by regulating clamp ring 13 to be locked by flexible seals 2, flexible seals 2 and running shaft 15 fitted tightly, strengthens sealing.
