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 stirring technique field, axle supporting oil leak proof device in a kind of Magnetic drive seal pot of specifically stirred tank Magnetic drive sealing.
Background technology
Stirred tank is the visual plant of the industries such as fine chemistry industry, water treatment, food and drink, biological medicine, its technological process usually requires in still to be vacuum or to have certain pressure, Magnetic drive sealing meets this requirement, realizes while power transmission, keep completely cutting off inside and outside still.The principle of Magnetic drive sealing is that still outer shaft is connected with power source and with outer magnetic assembly, the separation sleeve that outer magnetic assembly has passed isolating seal effect contactlessly passes to interior magnetic assembly power, interior magnetic assembly drives axle in still to rotate, and in still, axle drives the shaft agitator work of bottom.Current Problems existing is that the bearing lubricant that in still, axle supports there will be leakage, the medium not high for anti-pollution restriction seals in bearing bottom oil sealing, packing seal or mechanical seal usually, then lubricant of regularly annotating supplements the lubricant starvation that may occur.Require that high occasion strictly forbids lubricant leakage for anti-pollution, this is problem to be solved in Magnetic drive application.
Summary of the invention
The object of the invention is to overcome prior art deficiency and axle supporting oil leak proof device in a kind of Magnetic drive seal pot is provided.
The present invention solves the problems of the technologies described above adopted technical scheme: invent axle supporting oil leak proof device in a kind of Magnetic drive seal pot, comprise axle in still, bearing block, upper bearing (metal), lower bearing, axle sleeve, axial location round nut etc., axle sleeve contains oil cylinder with axle sleeve, its height is higher than upper bearing (metal) height, so both ensure that lubricant there will not be leakage, in turn ensure that bearing was in good lubricating status always.With axle sleeve positioning section on axle sleeve, usual way can be adopted to be fixed on by axle sleeve in still on axle.With blocking ring under bearing block flange, the splashing that medium can be avoided to occur enters axle sleeve and contains oil cylinder.Bearing block is positioned at upper bearing (metal) upper position with through hole, can in still, during lifting pressure, keep lubricant both sides to remain identical pressure, thus the lubricant avoiding pressure differential to cause departs from normal position.On axle sleeve with axle sleeve to contain cylinder upper end outside with helicitic texture, operationally, helicitic texture with block narrow and small annulated column gap that ring formed and utilize labyrinth effect to intercept possible the containing oil cylinder to axle sleeve and scurry into of splashing medium, the air flow power that during work, screw thread is formed when rotated just in time stops medium to contain oil cylinder to axle sleeve to scurry into, more ensure that and contain the non-interference of oil cylinder and medium.
The invention has the beneficial effects as follows: to solve in Magnetic drive sealing axle in still and support Leakage, ensure that Magnetic drive be sealed in stirred tank complete hermetic while can use in the occasion that anti-pollution requirement is strict again.
Accompanying drawing explanation
Fig. 1 is axle supporting oil leak proof device schematic diagram in a kind of Magnetic drive seal pot.
Fig. 2 is that the partial enlarged drawing of Fig. 1 is to express helicitic texture and to block ring.
In figure, 1. separation sleeve, magnetic assembly 2., 3. axle in still, 4. bearing block, 5. upper bearing (metal), 6. lower bearing, 7. stirred tank, 8. axle sleeve positioning section, 9. axle sleeve, 10. oil cylinder contained by axle sleeve, 11. helicitic textures, 12. axial location round nuts, 13, block ring, 14. construction bolt holes, 15. through holes.
Detailed description of the invention
In a kind of Magnetic drive seal pot shown in figure in axle supporting oil leak proof device embodiment, together with axle sleeve 9 to be installed to bearing block 4 by upper bearing (metal) 5 and lower bearing 6 and axial location round nut 12, bearing block 4 is positioned at upper bearing (metal) 5 upper position with through hole 15, the upper end that oil cylinder 10 contained by axle sleeve is outside with helicitic texture 11, axle sleeve 9 to be fixed in still on axle 3 by axle sleeve positioning section 8, interior magnetic assembly 2 is installed to axle 3 top in still, in still, the bottom of axle 3 connects shaft agitator, block the flange bottom that ring 13 is installed to bearing block 4, separation sleeve 1 and bearing block 4 are installed on stirred tank 7 by the bolt on construction bolt hole 14, separation sleeve 1 completely cuts off inside and outside still, the outer magnetic assembly effect that interior magnetic assembly 2 seals by the Magnetic drive of separation sleeve 1 outside rotates, axle 3 in still is driven to rotate, thus the shaft agitator of bottom works in drive still.
