Abstract
The utility model discloses a kind of scraper type centrifuge with sealing device, including main shaft, rotary drum, pedestal, the first sealing ring and the second sealing ring, main shaft drives drum rotating, rotary drum cover pedestal, have gap between rotary drum and pedestal；First sealing snare is on main shaft, and for the first sealing ring between pedestal and rotary drum, main shaft is in one section of covering exposed between pedestal and rotary drum by the first sealing ring；For second sealing snare on main shaft, the second sealing ring establishes dynamic sealing between main shaft and pedestal；The first sealing ring is arranged in the naked section of main shaft in the centrifuge of the utility model; so that main shaft surface and external environment are completely isolated; avoid main shaft surface by material and corroded by liquid; equipment inner components are effectively protected; the maintenance cycle and service life for extending equipment, reduce equipment operating cost.
Description
Technical field
The utility model relates to machinery equipment field more particularly to a kind of scraper type centrifuges with sealing device.
Background technique
In the prior art, when the main shaft drives drum rotating of 3-foot scraper type centrifuge, due to material and its steaming
The exposed part of the corroded by liquid main shaft of hair, it is easy to cause main shaft surface by Eroded, seal fails, liquid infiltration
Damage the parts such as bearing.The prior art, which generallys use the structure types such as labyrinth seal or turning circle sealing, prevents corroded by liquid master
Axis, but these technical effects are bad, it is naked when main shaft the reason is that the outerface of spindle cannot be completely isolated in above sealing mechanism
After dew part is etched, the sealing effect of all kinds of sealing rings is with a sharp decline.
Utility model content
It is same using sealing device the technical problem to be solved by the present invention is to provide a kind of novel scraper type centrifuge
The exposed part of step covering main shaft avoids causing seal failure because main shaft corrodes.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of scraper with sealing device
Formula centrifuge, including main shaft, rotary drum, pedestal, the first sealing ring and the second sealing ring, main shaft drives drum rotating, rotary drum cover
Pedestal has gap between rotary drum and pedestal；
First sealing snare is on main shaft, and for the first sealing ring between pedestal and rotary drum, the first sealing ring will be at main shaft
The exposed one section covering between pedestal and rotary drum；First sealing ring can use water-sealing sealing ring, and quantity is generally multiple, tool
Body quantity determines that the first sealing ring needs to be completely covered main shaft naked section according to the length of main shaft naked section；
For second sealing snare on main shaft, the second sealing ring establishes dynamic sealing between main shaft and pedestal.
First sealing ring avoids the exposed part of the corroded by liquid main shaft of material and its evaporation, guarantees the service life of main shaft
And the sealing effect between main shaft and the first sealing ring and the second sealing ring；Second sealing ring is for stopping on a small quantity through first
The liquid of sealing ring, prevents liquid entry into inside equipment.
Further, centrifuge further includes gland, and gland covers on main shaft and covers the second sealing ring.
Further, the gland is provided with the by-pass prot along gland radial direction, is existed by the liquid that the second sealing ring stops
Second sealing ring top accumulates and as main shaft rotates, and is discharged under the influence of centrifugal force by the by-pass prot of gland side.
The utility model has the advantages that the first sealing ring is arranged in the naked section of main shaft in the centrifuge of the utility model, so that main shaft surface
It is completely isolated with external environment, it avoids main shaft surface by material and corroded by liquid, equipment inner components is effectively protected, extend
The maintenance cycle and service life of equipment, reduces equipment operating cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of 1 centrifuge of embodiment.
Fig. 2 is the A enlarged drawing of Fig. 1.
Wherein: 1, main shaft；2, rotary drum；3, pedestal；4, the first sealing ring；5, the second sealing ring；6, gland；601, it bypasses
Hole.
Specific embodiment
The utility model is described in further detail With reference to embodiment.
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment be one have sealing device scraper type centrifuge, including main shaft 1, turn
Drum 2, pedestal 3, the first sealing ring 4, the second sealing ring 5 and gland 6；For the ease of observation, Fig. 1 of the present embodiment be illustrate only
The part directly related with sealing device, unshowned power part, transmission parts, scraper component etc. and in the prior art three
Sufficient formula scraper type centrifuge is consistent；
Main shaft 1 drives rotary drum 2 to rotate, and rotary drum 2 covers pedestal 3, has gap between rotary drum 2 and pedestal 3；
As shown in Fig. 2, 4 sets of the first sealing ring, on main shaft 1, the first sealing ring 4 is between pedestal 3 and rotary drum 2, first
Main shaft 1 is in one section of covering exposed between pedestal 3 and rotary drum 2 by sealing ring 4；First sealing ring 4 uses water-sealing sealing ring, number
Amount is generally multiple, and particular number determines (the present embodiment uses three water-sealing sealing rings) according to the length of 1 naked section of main shaft, the
One sealing ring 4 needs to be completely covered 1 naked section of main shaft；
For second 5 sets of sealing ring on main shaft 1, the second sealing ring 5 establishes dynamic sealing, gland 6 between main shaft 1 and pedestal 3
The second sealing ring 5 is covered on main shaft 1 and covers, gland 6 is provided with the by-pass prot 601 radial along gland 6.
At work, main shaft 1 drives rotary drum 2 to rotate to the centrifuge of the present embodiment, covers the first sealing ring 4 on main shaft 1
With 1 synchronous rotary of main shaft, static seal is kept between the first sealing ring 4 and rotary drum 2, is kept between the first sealing ring 4 and gland 6
Dynamic sealing keeps dynamic sealing between the second sealing ring 5 and main shaft 1.
1 naked section of main shaft is completely covered in first sealing ring 4, avoids the exposed of the corroded by liquid main shaft 1 of material and its evaporation
Part guarantees the sealing effect between the service life and main shaft 1 and the first sealing ring 4 and the second sealing ring 5 of main shaft 1；The
Two sealing rings 5 are used to stop to penetrate the liquid of the first sealing ring 4 on a small quantity, prevent liquid entry into inside equipment；By the second sealing ring 5
The liquid of blocking is accumulated above the second sealing ring 5 and as main shaft 1 rotates, under the influence of centrifugal force by 6 side of gland
By-pass prot 601 is discharged.
Although the embodiments of the present invention is illustrated in specification, these embodiments are intended only as mentioning
Show, should not limit the protection scope of the utility model.Various omissions are carried out in the range of not departing from the utility model aims, are set
It changes and change should be included in the protection scope of the utility model.
