Abstract
The utility model provides a sliding base bearing device of a stirring apparatus with long service life, which is characterized in that the bottom flange of a reactor is provided with a mandrel, the upper end of the mandrel is provided with a mandrel bushing, and the outer wall of the mandrel bushing is provided with a spiral groove matching with the rotating direction of a stirring shaft downwards. A moving shaft is fixedly sheathed with the lower end of the stirring shaft, and a moving shaft sleeve contains the mandrel bushing and the mandrel and rotates relative to the mandrel to form a sliding fit. The sliding base bearing device of a stirring apparatus with long service life has the advantages that the granular materials in medium can be effectively prevented from entering a fit clearance, abrasion between fit surfaces is reduced, service life is prolonged, maintenance is convenient, and cost is saved.
Description
Technical field: the utility model relates to a kind of stirrer slip base bearing, the stirrer slip base bearing device that particularly a kind of life-span is long.
Background technique: as shown in Figure 1, the basal sliding bearing that is used for fixing stirring shaft in the existing reactor, its form is, be provided with a bearing 4 ' in reactor 10 ' bottom, fix a tubular external axle sleeve 2 ' on bearing 4 ', the axle journal of stirring shaft 1 ' underpart 5 ' inserts in the axle sleeve 2 ' and constitutes the slip base bearing.The deficiency that this slip base bearing in use exists is, shot-like particle in the reactor 10 ' in the medium very easily enters the slide relative rubbing surface of axle journal 5 ' and axle sleeve 2 ' work, because this sliding friction surface is up open-ended, shot-like particle just very easily enters under the effect of gravity, thereby make the friction that generation is bigger between axle journal 5 ' and the axle sleeve 2 ' and then make its wearing and tearing and extremely inefficacy, just easier wearing and tearing when especially more the or hardness of contained shot-like particle is big in medium, obviously this is extremely unfavorable to the base bearing life-span.
Summary of the invention: the purpose of this utility model is at deficiency of the prior art, and proposes a kind of greatly reduce wear, and is durable in use, the slip base bearing device of the stirrer that the life-span is long.
Can realize the purpose of this utility model by following technical proposals, the stirrer slip base bearing device that a kind of life-span is long, it comprises the flange that is located at exterior edge face, reactor bottom, it is characterized in that, one axle is fixed on the flange by the hole of reactor bottom, one section fixed cover in the moving axis cover is in the lower end of stirring shaft, and another section becomes to be slidingly matched between them with the axle cover within it.
Its upper end portion of axle is with the axle lining, is processed to form on the axle lining outer wall with stirring shaft and turns to into the helix groove that downward guiding cooperates.
For preventing the blocked up matching gap of blocking base bearing of shot-like particle deposition in the medium of reactor bottom, put at moving axis and be provided with the cleaning blade.
The cross-section of helix groove can be circular arc, triangle, geometrical shape such as square.
The hardness and the abrasion resistance of axle lining material are lower than the moving axis cover.
Effect of the present utility model is that it can prevent effectively that the shot-like particle in the medium from entering in the matching gap of moving axis cover and axle lining, and it mainly achieves the goal by following three kinds of technological means; One, be the moving axis cover to be fixed on the stirring shaft lower ends downward axle and axle lining are inserted in it form movingly, the opening of its matching gap down, this shot-like particle phenomenon that original dependence gravity just can be entered in the matching gap no longer takes place, and has only the molecule that floats in the liquid can invade the gap; Its two, the hardness and the abrasion resistance of axle lining material are lower than the moving axis cover, make the axle lining in the wearing and tearing earlier of relative moving axis cover of when work, can reach to prolong the moving axis cover purpose in working life.Its three, axle sleeve outer surface design has helix groove, when stirring shaft rotated, its to the release of lower edge helix groove, entered molecule of sedimentation in matching gap in the medium; The cleaning blade that the while moving axis puts rotates thereupon, improves the turbulent velocity of reactor bottom medium, drives and arrange the fallout in the bottom, reduces near the granule density of the medium of base bearing, further reduces particulate matter and spreads in the bearing play.These three technological means can guarantee preferably that shot-like particle is not easy to be detained in matching gap, so just greatly lowered the abrasion between axle lining and the moving axis cover, make its energy durable in use, and reach reduction equipment user cost, improve the purpose of safe life.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing 1 is the prior art structural representation;
Accompanying drawing 2 is the utility model structural representation;
Embodiment: referring to accompanying drawing 2, the lower end of stirring shaft 1 is with moving axis cover 2, and it is fixing by bolt 3, and the bottom outer wall of reactor 10 is provided with the hole of a flange 4, one axles 5 by reactor 10 bottoms and is fixed on the flange 4.Axle 5 upper end portions are with wholeheartedly muff 6, and it is fixed on the axle 5 by bolt 7.Axle 5 is inserted in moving axis from lower to upper with axle lining 6 and overlaps in 2 hypomeres.Axle 5 also can be an integral body with axle lining 6.Axle 5 also can directly be inserted in moving axis and overlap in 2 hypomeres, but such effect is relatively poor.Outer wall at axle lining 6 is provided with the helix groove 8 that turns to into downward guiding cooperation with stirring shaft 1, its start-stop two-port lays respectively at the upper end portion and the underpart of axle lining 6 outer walls, its cross-section can be circular arc, triangle, geometrical shape such as square, when not establishing axle lining 6, helix groove 8 is directly processed on axle 5, plays effects equivalent.For making it, the shot-like particle overheap that does not make reactor 10 bottoms blocks the matching gap of base bearing, outer wall at moving axis cover 2 is fixed with cleaning blade 9, it can stir the medium of reactor bottom, gets up and reduce suspended particulate to enter matching gap thereby shot-like particle can not be piled up.The material hardness of axle lining 6 and abrasion resistance are overlapped 2 low than moving axis, this helps protecting moving axis cover 2, because the 6 more convenient replacings of axle lining, axle lining 6 materials can be selected according to the situation of medium.
