Description
Technical field
It the utility model is related to rotor shaft end seal, and in particular to a kind of ring hammer crusher rotor sealing structure of shaft end.
Background technology
Ring hammer crusher is one of capital equipment in thermal power plant coal handling system.When ring hammer crusher works,
Internal dust by rotor rotate caused by blast impact, device external is leaked to by the gap between housing side wall and axle,
Site environment is caused to pollute, infringement operator's health.The shaft end seal of existing ring hammer crusher is used in housing side wall and axle
Between gap filling asbestos packing, such a sealing means are because packing and axle mating surface are influenceed seriously by dust, working environment
Badly, easily wear, working life is short, and sealing effectiveness is poor.
The content of the invention
The purpose of this utility model be in view of the above-mentioned problems, provide it is a kind of can effectively improve its sealing reliability and
The ring hammer crusher rotor sealing structure of shaft end of working life.
Realizing the technical scheme of above-mentioned purpose is：A kind of ring hammer crusher rotor sealing structure of shaft end, including ring hammer type
Crusher shell side plate, armature spindle and the rotor discs being assemblied on the armature spindle, welded in the outboard end of the rotor discs
One and the concentric air baffle ring of the rotor discs are met, being connected by screw one center of installation in the lateral surface of the housing side plate sets
Round-meshed fixed plate, sealing shroud is provided with the center hole of the fixed plate, and the outside of the sealing shroud is provided with adpting flange and led to
Cross the flange to be fixedly connected on the lateral surface of the fixed plate, the center circle that the inside portion of the sealing shroud passes through the fixed plate
Hole and its medial extremity are extend into described air baffle ring, and disk is provided with the packing cavity formed between sealing shroud and armature spindle axial plane
Root, the outside of the packing are provided with packing gland, and the flange that the packing gland is set by its outside is fixed with described sealing shroud
Connection.
Above-mentioned ring hammer crusher rotor sealing structure of shaft end, described fixed plate, sealing shroud, packing gland are two halves
Body combining structure.
The utility model can effectively reduce dust to packing using air baffle ring and packing_seal combining structure, its air baffle ring
The influence of sealing, it is short to greatly improve functional reliability and the working life of packing_seal, makes the shaft end seal of ring hammer crusher
Performance greatly improves.
The utility model is simple in construction, and installation is changed simple and convenient.
Brief description of the drawings
Fig. 1 is this ring hammer crusher rotor shaft end sealed structural representation.
Fig. 2 is Fig. 1 A direction views.
In figure：1st, housing side plate；2nd, armature spindle；3rd, rotor discs；4th, air baffle ring；5th, fixed plate；6th, sealing shroud；7th, disk
Root；8th, packing gland.
Embodiment
Specific embodiment of the present utility model is illustrated with reference to accompanying drawing.
Such as Fig. 1, this ring hammer crusher rotor sealing structure of shaft end, including ring hammer crusher housing side plate 1, armature spindle
2 and it is connected through a screw thread the rotor discs 3 being assemblied on armature spindle 2.Outboard end welding one and this turn in the rotor discs 3
The concentric air baffle ring 4 of sub- disk 3, the air baffle ring 4 rotate with rotor.Connected in the lateral surface of the housing side plate 1 by screw
Connect one center of installation and set round-meshed fixed plate 5, be provided with sealing shroud 6 at the center hole of the fixed plate 5, the sealing shroud 6 outside
Side is provided with adpting flange and is fixedly connected on by the flange on the lateral surface of fixed plate 5, and the inside portion of the sealing shroud 6 passes through institute
State the center hole of fixed plate 5 and its medial extremity is extend into described air baffle ring 4, and form the aperture surface of air baffle ring 4 and sealing
Cover the gap fit structure of 6 outer diameter faces.The aperture surface of sealing shroud 6 is provided with packing annular groove, in the packing annular groove and the axial plane of armature spindle 2
Between be provided with packing 7 in the packing cavity that is formed, packing 7 can use the water base aramid fiber packing of height.The outside of packing 7 is provided with packing gland 8,
The flange that the packing gland 8 is set by its outside is fixedly connected with described sealing shroud 6.
Such as Fig. 2, the fixed plate 5 of this ring hammer crusher rotor sealing structure of shaft end, sealing shroud 6, packing gland 8 are adapted to set
Halved body combining structure is set to, is easily installed replacing.As accompanying drawing embodiment, fixed plate 5 are close using overlap joint halved body combining structure
Big envelope 6, packing gland 8 are using docking halved body combining structure.
This ring hammer crusher rotor sealing structure of shaft end is used in ring hammer crusher, when rotor rotation, in ring hammer type
Dust caused by inside disintegrating machine is first subjected to first of stop of air baffle ring, then is hindered by high water base aramid fiber packing second
Gear, realizes effective sealing of rotor shaft end, and reaches the purpose for effectively preventing dust from revealing.The presence of air baffle ring is effectively dropped simultaneously
Low harmful effect of the dust to packing_seal, substantially increase the working life and reliability of packing_seal.
