Abstract
The invention relates to a shaft supporting oil leak proof device in a magnetic driving sealed pot, which is applied to the stirring technical field, and solves the problem of oil leak of shaft supporting in the magnetic driving sealed pot. The invention is characterized in that a bearing arranged between a shaft and a bearing base is modified to a bearing arranged between a spindle sleeve and the bearing base, a oil holder is provided with a shaft sleeve, so that oil-proof state and bearing always in a good lubrication state can be realized, and the shaft supporting oil leak proof device provided in the invention is substituted of the previous sealing modes of oil sealing, filling material sealing and mechanical sealing. By cooperating with a through-hole on the bearing base as well as labyrinth effect between a screw structure on the shaft sleeve oil holder and a shield ring, the magnetic driving sealing is capable of ensuring a completely sealing to the stirred pot and using in the occasions required strict anti-pollution performance.
Description
Technical field
The invention belongs to the stirring technique field, specifically axle supports anti-oil leakage device in a kind of magnetic transmission seal still of stirred tank magnetic transmission seal.
Background technology
Stirred tank is the visual plant of industries such as fine chemistry industry, water treatment, food and drink, biological medicine, its technological process usually requires in the still to be vacuum or to have certain pressure, the magnetic transmission seal has satisfied this requirement, keeps inside and outside the completely cutting off of still when being implemented in the power transmission.The principle of magnetic transmission seal is that the still outer shaft is connected and has outer magnetic assembly with power source, the separation sleeve that outer magnetic assembly has passed the isolating seal effect contactlessly passes to interior magnetic assembly to power, interior magnetic assembly drives axle rotation in the still, and axle drives the shaft agitator work of bottom in the still.The problem that exists is that leaking can appear in the bearing lubricant that axle supports in the still at present, the medium not high for anti-pollution restriction seals with oil sealing, packing seal or mechanical seal in the bearing bottom usually, and the lubricant of regularly annotating again replenishes the lubricant starvation that may occur.Forbid that for anti-pollution demanding occasion strictness lubricant leaks, this is a problem to be solved in the magnetic transmission application.
Summary of the invention
The objective of the invention is to overcome the prior art deficiency and axle support anti-oil leakage device in a kind of magnetic transmission seal still is provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: invent axle support anti-oil leakage device in a kind of magnetic transmission seal still, comprise axle, bearing block, upper bearing (metal), lower bearing, axle sleeve, axial location round nut etc. in the still, have axle sleeve on the axle sleeve and contain oil cylinder, it highly is higher than the upper bearing (metal) height, so both guaranteed that leaking can not appear in lubricant, guaranteed again that bearing was in good lubricating status always.Have the axle sleeve positioning section on the axle sleeve, can adopt usual way that axle sleeve is fixed in the still on the axle.Have under the bearing block flange and block ring, splashing of can avoiding that medium may occur enters axle sleeve and contains oil cylinder.Be positioned at the upper bearing (metal) upper position on the bearing block and have through hole, can be in still keep the lubricant both sides to remain identical pressure during lifting pressure, thereby the lubricant of avoiding pressure differential to cause breaks away from normal position.The axle sleeve that has on the axle sleeve is contained outside, oil cylinder upper end and is had helicitic texture, when work, helicitic texture utilizes the labyrinth effect to intercept possible the scurrying into to axle sleeve Sheng oil cylinder of the medium that splashes with the narrow and small annulated column slit of blocking ring formation, the air-flow power that screw thread forms when rotated during work just in time stops medium to be scurried into to axle sleeve Sheng oil cylinder, has more guaranteed to contain the mutually noninterfere of oil cylinder and medium.
The invention has the beneficial effects as follows: solved the interior axle support of still leakage of oil problem in the magnetic transmission seal, guaranteed that the magnetic transmission seal can use in anti-pollution strict occasion again when stirred tank is sealed fully.
Description of drawings
Fig. 1 is that axle supports the anti-oil leakage device schematic diagram in a kind of magnetic transmission seal still.
Fig. 2 is that the partial enlarged drawing of Fig. 1 is to express helicitic texture and to block ring.
Among the figure, 1. separation sleeve, 2. in magnetic assembly, 3. axle, 4. bearing block, 5. upper bearing (metal) in the still, 6. lower bearing, 7. stirred tank, 8. axle sleeve positioning section, 9. axle sleeve, 10. axle sleeve is contained oil cylinder, 11. helicitic textures, 12. the axial location round nut, 13, block ring, 14. construction bolt holes, 15. through holes.
The specific embodiment
Axle supports among the anti-oil leakage device embodiment in a kind of magnetic transmission seal still shown in the figure, axle sleeve 9 is installed to bearing block 4 by upper bearing (metal) 5 and lower bearing 6 and axial location round nut 12, be positioned at upper bearing (metal) 5 upper positions on the bearing block 4 and have through hole 15, the outside, upper end that axle sleeve is contained oil cylinder 10 has helicitic texture 11, by axle sleeve positioning section 8 axle sleeve 9 is fixed in the still on the axle 3, interior magnetic assembly 2 is installed to axle 3 tops in the still, the bottom of axle 3 connects the shaft agitator in the still, block the flange bottom that ring 13 is installed to bearing block 4, separation sleeve 1 and bearing block 4 are installed on the stirred tank 7 by the bolt on the construction bolt hole 14, inside and outside the separation sleeve 1 isolated still, interior magnetic assembly 2 is rotated by the outer magnetic assembly effect of the magnetic transmission seal of separation sleeve 1 outside, drive axle 3 rotations in the still, thereby drive the shaft agitator work of bottom in the still.
