Description
Technical field
The present invention relates to mechanical seal fields, and in particular to a kind of Large Underwater pelleter cutter shaft mechanical seal.
Background technique
Large Underwater pelleter is the core equipment of entire large-scale pugging extruder group, previous domestic underwater pelletizer
Volume range is no longer satisfied 300,000 tons/year of yield or more of large-scale mixing extrusion pelleting machine set demand, thus develop with
The matched Large Underwater pelleter of its volume range, while needing to develop a kind of matching cutter mechanical seal for axle,
And improve, upgrade on the basis of previous mechanical seal structure, use experience, as shown in Fig. 2, the inner hole of existing machinery sealing
It is excessive with the gap of cutter shaft, it causes material clast to be deposited in gap, gathers and will cause mechanical seal failure, water chamber for a period of time
Interior water leakage.
Summary of the invention
Problem that the purpose of the present invention is to overcome the above shortcomings provides a kind of structure innovation, convenient for disassembly and assembly, service life
Large Underwater pelleter cutter shaft mechanical seal long, sealing effect is good.
Present invention technical solution used for the above purpose is: Large Underwater pelleter cutter shaft mechanical seal, packet
Stationary ring, rotating ring, movable sleeving, fixing sleeve are included, the stationary ring, moving ring sleeve are formed close on slitter shaft between the stationary ring, rotating ring
Cover, the movable sleeving are sleeved on stationary ring, rotating ring, on slitter shaft, and the fixing sleeve is sleeved on movable sleeving, on the movable sleeving
It is cased with water chamber, the stationary ring is connect with fixing sleeve, the rotating ring and cutter axis connection, by the between the rotating ring and slitter shaft
The sealing of four O-ring seals, is sealed between the movable sleeving and fixing sleeve by the first O-ring seal and third O-ring seal, institute
Fixing sleeve and water chamber is stated to seal by the second O-ring seal.
The stationary ring is connected by screw to fixing sleeve.
The rotating ring is connected by key with slitter shaft.
The invention has the characteristics that avoiding material talus accumulation using outer flushing mechanism, the leakproofness of mechanical seal ensure that
Can, while sealing surface can be cooled down, the temperature of mechanical seal rubbing surface is reduced, making for mechanical seal is significantly increased
With the service life, and it is convenient for disassembly and assembly, greatly reduce the labor intensity of replacement, checking maintenance.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present invention, constitutes a part of the invention, this hair
Bright illustrative embodiments and their description are used to explain the present invention, and are not constituted improper limitations of the present invention.
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is existing machinery sealed structural schematic diagram.
Wherein: 1, screw 2, the first O-ring seal 3, the second O-ring seal 4, stationary ring 5, rotating ring 6, third
O-ring seal 7, movable sleeving 8, key 9, slitter shaft 10, fixing sleeve 11, water chamber 12, the 4th O-ring seal.
Specific embodiment
If used some vocabulary in the specification and claims to censure specific components, those skilled in the art are answered
It is understood that hardware manufacturer may call the same component with different nouns, this specification and claims are not with name
The difference of title is such as being led to as the mode for distinguishing component, but with the difference of component functionally as the criterion of differentiation
The "comprising" of piece specification and claim mentioned in is an open language, therefore should be construed to " include but do not limit
In ", " substantially " refers within the acceptable error range, those skilled in the art can within a certain error range solve described in
Technical problem basically reaches the technical effect, and specification subsequent descriptions are to implement better embodiment of the invention, so described
Description is the range being not intended to limit the invention for the purpose of illustrating rule of the invention, protection scope of the present invention
As defined by the appended claims.
Below in conjunction with invention is further described in detail shown in attached drawing 1, but it is not as a limitation of the invention.
The present invention is a kind of Large Underwater pelleter cutter shaft mechanical seal, including stationary ring 4, rotating ring 5, movable sleeving 7, fixing sleeve
10, the stationary ring 4, rotating ring 5 are sleeved on slitter shaft 9, form sealing surface between the stationary ring 4, rotating ring 5, and pass through bellows
It compresses, sealed friction surface material uses graphite alloy, and the movable sleeving 7 is sleeved on stationary ring 4, rotating ring 5, on slitter shaft 9, described solid
Surely set 10 is sleeved on movable sleeving 7, and water chamber 11 is cased on the movable sleeving 7, and the stationary ring 4 is connected with fixing sleeve 10 by screw 1
It connects, the rotating ring 5 is connect with slitter shaft 9 by key 8, close by the 4th O-ring seal 12 between the rotating ring 5 and slitter shaft 9
Envelope is sealed between the movable sleeving 7 and fixing sleeve 10 by the first O-ring seal 2 and third O-ring seal 6, the fixing sleeve
10 and water chamber 11 pass through the second O-ring seal 3 seal.
Present invention decreases the gap of the inner hole of mechanical seal and slitter shaft 9, tiny material accumulation is prevented, and is rinsed outside
Water enters outside stationary ring, from water chamber 11 is flowed between the inner hole and slitter shaft 9 of mechanical seal, can effectively prevent fines
The accumulation of material ensure that the sealing performance of mechanical seal, reduces the temperature of mechanical seal rubbing surface, significantly increases machinery
The service life of sealing, it is convenient for disassembly and assembly, greatly reduce the labor intensity of replacement, checking maintenance.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
