Abstract
The utility model discloses a sanitary bottom bearing for stirring fluid, which comprises a stirring shaft, wherein a permanent magnetic type internal magnetic steel assembly and a permanent magnetic type external magnetic steel assembly are concentrically arranged at the outside of the bottom part of the stirring shaft in sequence, the permanent magnetic type internal magnetic steel assembly and the permanent magnetic type external magnetic steel assembly have the same polarity and are arranged in a clearance manner, the permanent magnetic type external magnetic steel assembly is fixed on a tank body through a supporting leg, and the permanent magnetic type internal magnetic steel assembly is in friction transmission with the stirring shaft through a taper sleeve. The sanitary bottom bearing disclosed by the utility model is simple in structure, convenient to install and low in manufacturing cost, non-contact centering is realized by means of the principle of homopolar repulsion of magnetic steel to avoid materials in a kettle from being polluted due to contact movable friction, so that the sanitary bottom bearing can be used under sanitary working conditions, and meanwhile, the design of the structure can ensure all positions of the equipment to be cleaned without accumulating liquid at all, no cleaning dead angle is left, and no attrition exists, so that the sanitary bottom bearing can be used for long time.
Description
Technical field
The utility model relates to shaft base bearing in a kind of stirred tank, is specifically related to a kind of long service life, and can antipollution fluid agitation sanitation-grade base bearing.
Background technology
At present, the bottom bearing that fluid agitation equipment is used adopts the contact bearing mostly, this point mode, inevitable owing to existing fretting corrosion to pollute the result of material in still, and the bearing of phase mutual friction or stirring frequent replacing due to abrasion, so can not use bottom bearing in the operating mode of sanitation-grade, this has just increased the design difficulty that stirs.If speed of agitator is not high, only have by increasing the shaft diameter to be designed to stiff cantilevers axle system, so not only can increase the cost of shaft but also can increase the cost that seals on axle; If speed of agitator is very high, only be designed to can not dry run the flexible cantilever shafting structure, flexible shaft system tends to because operational issue causes scrapping of whole mixing plant and may be unworkable due to the free fortune of operation operating mode.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, long service life is provided, and the fluid agitation sanitation-grade base bearing that can use in the sanitation-grade operating mode.
A kind of fluid agitation sanitation-grade base bearing comprises shaft; The outer interior magnet steel sub-assembly of permanent magnetism, the permanent magnetism outer steel sub-assembly of being provided with one heart successively in described shaft bottom, in described permanent magnetism, the magnet steel sub-assembly is identical with the polarity of permanent magnetism outer steel sub-assembly, and be the gap and arrange, described permanent magnetism outer steel sub-assembly is fixed on tank body by supporting leg, and the magnet steel sub-assembly is realized by coning sleeve and the frictional drive of shaft in described permanent magnetism.
In described permanent magnetism, magnet steel sub-assembly and permanent magnetism outer steel sub-assembly are wrapped with the stainless steel jacket.
The utility model is simple in structure, easy for installation, low cost of manufacture is utilized the principle of magnet steel homopolar-repulsion, realize non-contact type centering, the situation of avoiding polluting material in still due to the moving fretting corrosion of contact occurs, and can use in the operating mode of sanitation-grade, and the design of this structure simultaneously can guarantee that the equipment all sites can clean, hydrops not fully, do not stay the corner or spot as yet untouched by a clean-up campaign, without wearing and tearing, can use for a long time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for explanation the utility model but not for limiting scope of the present utility model.
Embodiment 1
Referring to Fig. 1, a kind of fluid agitation sanitation-grade base bearing that the utility model provides, comprise shaft 1, be provided with one heart successively magnet steel sub-assembly 2, permanent magnetism outer steel sub-assembly 3 in permanent magnetism outside described shaft 1 bottom, in described permanent magnetism, magnet steel sub-assembly 2 is identical with the polarity of permanent magnetism outer steel sub-assembly 3, and be the gap and arrange, described permanent magnetism outer steel sub-assembly 3 is fixed on tank body 5 by supporting leg 4, and in described permanent magnetism, magnet steel sub-assembly 2 is by the frictional drive of coning sleeve 6 realizations with shaft 1.
Due to the magnetic force that is subject to the circumference uniform distribution homopolar-repulsion, as long as radially wobble power when the repulsion between the internal-external magnetic steel sub-assembly turns round greater than shaft, shaft will be limited in center, the gap running of internal-external magnetic steel sub-assembly, and internal-external magnetic steel disengages friction fully.
Magnet steel sub-assembly 2 and permanent magnetism outer steel sub-assembly 3 are wrapped with stainless steel jacket 7 in described permanent magnetism, and stainless steel jacket 7 seals interior magnet steel and outer steel sub-assembly fully, and all sites can clean, and hydrops not, do not stay the corner or spot as yet untouched by a clean-up campaign fully.
Claims (2)
1. fluid agitation sanitation-grade base bearing, comprise shaft, it is characterized in that: the outer interior magnet steel sub-assembly of permanent magnetism, the permanent magnetism outer steel sub-assembly of being provided with one heart successively in described shaft bottom, in described permanent magnetism, the magnet steel sub-assembly is identical with the polarity of permanent magnetism outer steel sub-assembly, and be the gap and arrange, described permanent magnetism outer steel sub-assembly is fixed on tank body by supporting leg, and the magnet steel sub-assembly is realized by coning sleeve and the frictional drive of shaft in described permanent magnetism.
2. fluid agitation according to claim 1 sanitation-grade base bearing is characterized in that: in described permanent magnetism, magnet steel sub-assembly and permanent magnetism outer steel sub-assembly are wrapped with the stainless steel jacket.
