Abstract
The utility model discloses the high temperature powder mechanical seals that a kind of resistance to pitch of Anti-powder-leakage is adhered agglomeration, including covering the axle sleeve on main shaft, packing seal, three-clove style labyrinth seal and mechanical seal are set gradually on axle sleeve from nearly autoclave body side, the three-clove style labyrinth seal withstands fixation using throw-out collar and spring, and the mechanical seal is configured with graphite pads；Shell is equipped on the outside of the packing seal, three-clove style labyrinth seal and mechanical seal it is fixed.The utility model can be resistant to 650 DEG C of temperature, and high temperature powder in container is completely cut off completely and prevents the stability remained operational inside powder invasion mechanical seal in the case where asphalt volatile constituents are adhered and even agglomerate.Meanwhile with tradition machinery sealing compared with, the service life of the utility model extends 3 times or more, reduces the repair time, improves production efficiency, save trouble saving of labor and prevented powder race leakage, clean manufacturing, Environmental Safety significant effect.
Description
Technical field
The utility model relates to the high temperature powder mechanical seals that a kind of resistance to pitch of Anti-powder-leakage is adhered agglomeration.
Background technique
Mechanical seal is a kind of gland seal device of rotating machinery.For example centrifugal pump, centrifuge, reaction kettle and compressor etc. are set
It is standby, since transmission shaft is applied in inside and outside equipment, there are a circumferential clearance between axis and equipment, medium in equipment by should between
Gap leaks out, if pressure is subatmospheric in equipment, air is to equipment internal leakage, it is therefore necessary to have a prevention leakage
Gland seal device.There are many type of axle envelope, since mechanical seal has many advantages, such as that leakage rate is few and the service life is long, so mechanical seal
It is most important sealing mode.Mechanical seal is called end face seal, is defined such that in relative national standards " by extremely
Few a pair of effect and auxiliary seal perpendicular to the end face of rotation axis in Fluid pressure and compensation mechanism elastic force (or magnetic force)
Cooperation under keep be bonded and constituted with respect to sliding prevent fluid leak device."
For the mechanical seal that powder industry (lithium electro-graphitic negative electrode material) is selected, using temperature no more than 550 DEG C, by
In temperature in the kettle height, machine envelope with material directly contact and have pitch volatilization can be adhered even agglomerate, generally be easy leakage, use the longevity
Life is not grown, and is begun within general three months or so powder leakage, and can not repair, is needed thoroughly to replace.
Utility model content
The case where the purpose of this utility model is emphatically for powder leakage, by changing the structure of tradition machinery sealing, provides
The resistance to pitch of Anti-powder-leakage is adhered the high temperature powder mechanical seal of agglomeration, prevents stiffening device using multiple tracks, prevents powder leakage, greatly
Extend the service life of this structure machine envelope.
The purpose of this utility model is achieved through the following technical solutions:
A kind of resistance to pitch of Anti-powder-leakage is adhered the high temperature powder mechanical seal of agglomeration, including covering the axle sleeve on main shaft,
Packing seal, three-clove style labyrinth seal and mechanical seal, the three-clove style fan are set gradually on axle sleeve from nearly autoclave body side
Palace sealing withstands fixation using throw-out collar and spring, and the mechanical seal is configured with graphite pads；In the packing seal, three valves
Shell is equipped on the outside of formula labyrinth seal and mechanical seal it is fixed.
The utility model has the beneficial effects that
The utility model is selecting packing seal to obstruct leaking for material close to autoclave body close to autoclave body side first, the
Two select three-clove style labyrinth seal, and sealed medium generates throttle effect when through the gap in tortuous labyrinth and reaches Drain Resistance
Purpose, third road choosing be water-cooled refractory machinery seals, be equipped with high-temperature flexible graphite pads.Entire mechanical seal can be resistant to
High temperature powder in container is completely cut off completely and is prevented inside powder invasion mechanical seal by 650 DEG C of temperature, glutinous in asphalt volatile constituents
The stability remained operational in the case where even even agglomerating.Meanwhile compared with tradition machinery sealing, the utility model uses the longevity
Life extend 3 times or more, reduce the repair time, improve production efficiency, save trouble saving of labor and prevented powder race leakage, cleaning
Production, Environmental Safety significant effect.
Detailed description of the invention
Fig. 1 is the structural representation for the high temperature powder mechanical seal that the resistance to pitch of the utility model Anti-powder-leakage is adhered agglomeration
Figure.
Specific embodiment
The technical solution of the utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, a kind of resistance to pitch of Anti-powder-leakage is adhered the high temperature powder mechanical seal of agglomeration, including cover in main shaft
Axle sleeve 2 on 1 sets gradually packing seal 3, three-clove style labyrinth seal 4 and mechanical seal 5 from nearly autoclave body side on axle sleeve,
The three-clove style labyrinth seal 4 withstands fixation using throw-out collar 6 and spring 7, and the mechanical seal 5 is configured with graphite pads；?
Shell 8 is equipped on the outside of packing seal 3, three-clove style labyrinth seal 4 and the mechanical seal 5 it is fixed.
The present embodiment is selecting packing seal to come close to autoclave body close to autoclave body side first, obstructs leaking for material, and second
Three-clove style labyrinth seal is selected in road, and sealed medium generates throttle effect when through the gap in tortuous labyrinth and reaches Drain Resistance
Purpose, the choosing of third road are water-cooled refractory machinery seals, are equipped with high-temperature flexible graphite pads.Entire mechanical seal can be resistant to
High temperature powder in container is completely cut off completely and is prevented inside powder invasion mechanical seal by 650 DEG C of temperature, glutinous in asphalt volatile constituents
The stability remained operational in the case where even even agglomerating.Meanwhile compared with tradition machinery sealing, the service life of the present embodiment
Extend 3 times or more, reduce the repair time, improve production efficiency, save trouble saving of labor and prevented powder race leakage, cleaning life
It produces, Environmental Safety significant effect.
