Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is the shaft sealer stirring mortar equipment (as mortar mixer) diameter of axle place leakage proof.
As shown in Figure 1, the utility model comprises O type circle 1, interior bag skeleton lip oil sealing 2, lip sealed cover 3, packing gland 4, packing housing screw 5, oil immersion cotton packing 6, sealing rubber pad 9, packing cover 10 and gets rid of mud plate 11, the frame 18 of stirring mortar equipment is rotatably connected to stirring shaft 7, this stirring shaft 7 is connected with bearing 13, and bearing 13 is contained in bearing support 14.Stirring shaft 7 is arranged with packing cover 10, this packing cover 10 in the middle of has through hole, outer surface vertically journey is stepped, and extends radially outward at outer surface, extension part by screw and frame 18 affixed.Sealing rubber pad 9 is provided with between the extension part of packing cover 10 and frame 18, under screw effect, fit tightly between extension part on packing cover 10, sealing rubber pad 9, frame 18, the gap (i.e. breakthrough B17) overlapped frame 18 and packing between the extension part on 10 seals.
Packing cover 10 is provided with axle sleeve 8 along one end of stirring shaft 7 axis, and this axle sleeve 8 is fixed on stirring shaft 7, rotates with stirring shaft 7, and overlaps one end Spielpassung of 10 with packing, and to ensure when stirring shaft 7 rotates, axle sleeve 8 and packing overlap 10 does not have scratching phenomenon to occur; Packing cover 10 is connected with packing gland 4 along the other end of stirring shaft 7 axis by packing housing screw 5, this packing gland 4 is set on stirring shaft 7, centre has intermediate hole, axial cross section is "T"-shaped, "T"-shaped horizontal edge is perpendicular to the longitudinal center line of stirring shaft 7, and be threaded by the other end that packing housing screw 5 and packing overlap 10, packing gland 4 and packing are Spielpassung between overlapping 10.Oil immersion cotton packing 6 is filled with in the space formed between packing cover 10 and stirring shaft 7, packing gland 4 produces mobile by the pretightening force effect of packing housing screw 5, oil immersion cotton packing 6 is made to produce compression, oil immersion cotton packing 6 after compression is pressed on the end face of axle sleeve 8 towards the front of axle sleeve 8 side, the through-hole wall face close contact of 10 is then overlapped in the side of oil immersion cotton packing 6 with packing, geo-stationary, form static seal, thus the gap (i.e. breakthrough A16) that axle sleeve 8 and packing are overlapped between 10 is plugged, and then reach the object of sealing.
The part of stirring shaft 7 between packing gland 4 and bearing 13 circumferentially has groove, is fixed with and gets rid of mud plate 11 in groove.Getting rid of mud plate 11 is two semicircular plates, and the surface, the same side (the present embodiment is at the side surface towards packing gland 4) at each semicircular plate two ends is equipped with joint 19, and two semicircular plates are connected by two bolts at this joint 19 place.Two semicircular gets rid of in groove that mud plate 11 is fixed on stirring shaft 7, rotates with stirring shaft 7.When the diameter of axle having liquid slurry along stirring shaft 7 is leaked out by oil immersion cotton packing 6, under the influence of centrifugal force, throw away along the edge getting rid of mud plate 11, avoid it to flow in bearing support 14 along the diameter of axle, damage bearing 13.
Be provided with the bearing gland 12 be enclosed within stirring shaft 7 towards the side of getting rid of mud plate 11 at bearing 13, bearing gland 12 and stirring shaft 7 are Spielpassung; Bearing gland 12 and get rid of the lip sealed cover 3 being provided with between mud plate 11 and being set on stirring shaft 7, this lip sealed cover 3 and stirring shaft 7 Spielpassung, and be fixed on bearing gland 12 by bolt.Interior bag skeleton lip oil sealing 2 is provided with between lip sealed cover 3 and stirring shaft 7, this interior bag skeleton lip oil sealing 2 is pressed on stirring shaft 7 by lip sealed cover 3, the liquid slurry along stirring shaft 7 seepage can be prevented, sealing is formed to bearing 13, play again and stop that extraneous dust enters into the effect in bearing support 14, avoid bearing 13 to lose efficacy.
Bearing gland 12 inwall has groove, and O type circle 1 is rotated in the groove of bearing gland 12 inwall, with stirring shaft 7 interference fit, forms sealing to bearing 13.
Working principle of the present utility model is:
When stirring shaft 7 rotates at work, liquid slurry determined by the character of self, will be full of all gaps, and such as axle sleeve 8 and packing overlap breakthrough A16 between 10, packing overlaps breakthrough B17 between 10 and frame 18; If do not controlled, then will produce waste to raw material, to environment, damage be caused to bearing 13.
For breakthrough B17, owing to there is no relative movement between each part, under the effect of screw pretightening force, utilize the resiliently deformable of sealing rubber pad 9, make no longer to produce even small gap between frame 18 and packing cover 10, and then the static seal realized liquid slurry, block liquid slurry seepage outwardly.
For breakthrough A16, owing to having relative movement between each part, so higher to the requirement of sealing.The utility model is to initial part gap place (breakthrough A16), utilize the pretightening force effect of packing housing screw 5, oil immersion cotton packing 6 is compressed by packing gland 4, oil immersion cotton packing 6 is made to be close on the transverse section of axle sleeve 8, the side of oil immersion cotton packing 6 is close to packing and overlaps on the internal face of 10 through holes, and block the gap at breakthrough A16 place, avoid liquid slurry along the diameter of axle seepage of stirring shaft 7.This is first seal arrangement, is also the topmost seal arrangement of the utility model.
If oil immersion cotton packing 6 was lost efficacy, then liquid slurry outwards will overflow along stirring shaft 7.In trickling to when getting rid of mud plate 11 place, be together rotate with stirring shaft 7 owing to getting rid of mud plate 11, liquid slurry will under the influence of centrifugal force, fly off at a tangent along getting rid of the outer of mud plate 11, away from bearing 13, and then reaches the object of protection bearing 13.This is second seal arrangement.
If also have raffinate to continue outside seepage by the groove joint of getting rid of mud plate 11 and stirring shaft 7, then by follow-up sealing configuration, namely, bag skeleton lip oil sealing 2 and O type circle 1 carry out shutoff.This two seals is not rotated with stirring shaft 7, and they are only the outsides relying on deformation elastic force during assembling to be wrapped in stirring shaft 7, plays preventing again extraneous foreign matter from entering into bearing support 14 while liquid slurry plugging action inner, damage bearing 13.This is the third and fourth road sealing device.
By this sealer with assembled of the utility model, liquid slurry effectively can be avoided to flow out along the gap between the diameter of axle and Sealing of stirring shaft 7, thus reach saving material, reduce costs, protection of the environment, the object boosted productivity.
