Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
The present invention is the sealing of antiseep at stirring mortar equipment (such as the mortar mixer) diameter of axle
Device.
As it is shown in figure 1, the present invention includes that O 1, interior bag skeleton lip oil sealing 2, lip seal
Gland 3, packing gland 4, packing housing screw 5, oil immersion cotton packing 6, sealing rubber pad 9,
Packing overlaps 10 and gets rid of mud plate 11, and the frame 18 of stirring mortar equipment is rotatably connected to stirring
Axle 7, this shaft 7 connects and has bearing 13, bearing 13 to be contained in bearing block 14.Stir
Mixing and be arranged with packing set 10 on axle 7, have through hole in the middle of this packing set 10, outer surface is along axle
Stepped to journey, and extend radially outward at outer surface, extension passes through screw and frame
18 is affixed.It is provided with sealing rubber pad 9, at spiral shell between extension and the frame 18 of packing set 10
Under nail effect, packing overlaps between the extension on 10, sealing rubber pad 9, frame 18 tight
Laminating, overlaps the gap (i.e. breakthrough B17) between the extension on 10 to frame 18 and packing
Seal.
Packing set 10 is provided with axle sleeve 8 along one end that shaft 7 is axial, and this axle sleeve 8 is fixed in
On shaft 7, rotate with shaft 7, and overlap one end matched in clearance of 10 with packing, with
Ensureing when shaft 7 rotates, axle sleeve 8 does not has scratching phenomenon to occur with packing set 10；Dish
Root set 10 has packing pressure along the other end that shaft 7 is axial by packing housing screw 5 connection
Lid 4, this packing gland 4 is set on shaft 7, and centre has interstitial hole, axial cross section
For "T"-shaped, "T"-shaped horizontal edge is perpendicular to the longitudinal center line of shaft 7, and passes through dish
Root housing screw 5 is threadeded with the other end of packing set 10, packing gland 4 and packing set
It it is matched in clearance between 10.Fill in the space formed between packing set 10 and shaft 7
Oil immersion cotton packing 6, packing gland 4 is had to be produced by the pretightning force effect of packing housing screw 5
Mobile, make oil immersion cotton packing 6 produce compression, the oil immersion cotton packing 6 after compression is towards axle sleeve 8
The front of side is pressed on the end face of axle sleeve 8, the side of oil immersion cotton packing 6 then with packing set
The through-hole wall face of 10 is in close contact, geo-stationary, forms static seal, so that axle sleeve 8
And the gap (i.e. breakthrough A16) between packing set 10 is plugged, and then reaches sealing
Purpose.
The shaft 7 part between packing gland 4 and bearing 13 circumferentially has groove,
It is fixed with in groove and gets rid of mud plate 11.Getting rid of mud plate 11 is two semicircular plates, each semicircular plate
The surface, the same side (the present embodiment is at the side surface towards packing gland 4) at two ends is upper all
Being provided with connecting portion 19, two semicircular plates are connected by two bolts at this connecting portion 19.
Two semicircular mud plates 11 that get rid of are fixed in the groove on shaft 7, revolve with shaft 7
Turn.When there being the liquid slurry diameter of axle along shaft 7 to be leaked out by oil immersion cotton packing 6,
Under the effect of centrifugal force, throw away along the edge getting rid of mud plate 11, it is to avoid it is flowed into axle along the diameter of axle
In bearing 14, damage bearing 13.
It is provided with the bearing gland being enclosed within shaft 7 towards the side getting rid of mud plate 11 at bearing 13
12, bearing gland 12 and shaft 7 are matched in clearance；Bearing gland 12 with get rid of mud plate 11
Between be provided with the lip sealed cover 3 being set on shaft 7, this lip sealed cover 3 and shaft 7
Matched in clearance, and be fixed on bearing gland 12 by bolt.Lip sealed cover 3 and shaft
Being provided with interior bag skeleton lip oil sealing 2 between 7, this interior bag skeleton lip oil sealing 2 is by lip envelope pressure
Lid 3 is pressed on shaft 7, can prevent the liquid slurry along shaft 7 seepage, countershaft
Hold 13 formation to seal, play again and stop that extraneous dust enters into the effect in bearing block 14,
Bearing 13 is avoided to lose efficacy.
Bearing gland 12 inwall has groove, and O 1 is rotated in bearing gland 12 inwall
In groove, with shaft 7 interference fit, bearing 13 is formed and seals.
The operation principle of the present invention is:
When shaft 7 rotates at work, liquid slurry is determined by the character of self, must
Will be filled with the breakthrough A16 between all of gap, such as axle sleeve 8 and packing set 10, dish
Breakthrough B17 between root set 10 and frame 18；If be not controlled by, then will be to raw material
Produce waste, to environment, bearing 13 is caused damage.
For breakthrough B17, owing to there is no relative motion between each part, in screw pretightning force
Effect under, utilize the elastic deformation of sealing rubber pad 9, make frame 18 and packing set 10 it
Between no longer produce even small gap, and then realize the static seal to liquid slurry, block
Liquid slurry seepage outwardly.
For breakthrough A16, owing to having relative motion between each part, so to sealing
Require higher.The present invention, to (breakthrough A16) at initial part gap, utilizes packing
The pretightning force effect of housing screw 5, compresses oil immersion cotton packing 6 by packing gland 4, makes oil
Leaching cotton packing 6 is close on the transverse section of axle sleeve 8, and the side of oil immersion cotton packing 6 is close to dish
Root overlaps on the internal face of 10 through holes, and blocks the gap at breakthrough A16, it is to avoid slush pulp
Expect the diameter of axle seepage along shaft 7.This is first sealing device, is also that the present invention is main
Sealing device.
If oil immersion cotton packing 6 was lost efficacy, then liquid slurry outwards will overflow along shaft 7.?
Trickling, to when getting rid of at mud plate 11, is to rotate together with shaft 7 owing to getting rid of mud plate 11, liquid
Slurry will fly off at a tangent, far along getting rid of the outer of mud plate 11 under the influence of centrifugal force
Hold 13 off axis, and then reach to protect the purpose of bearing 13.This is second sealing device.
If also residual liquid outwards continues by getting rid of the groove junction of mud plate 11 and shaft 7
Seepage, then by follow-up sealing structure, i.e. interior bag skeleton lip oil sealing 2 and O 1 enter
Row closure.This two seals does not rotates with shaft 7, shape when they are only to rely on assembling
Become elastic force and be wrapped in the outside of shaft 7, play and again can to while liquid slurry plugging action
Prevent extraneous foreign body from entering into bearing block 14 internal, damage bearing 13.This is third and fourth
Road sealing device.
By this sealer with assembled of the present invention, it is possible to be effectively prevented from liquid slurry along stirring
Mix the gap between the diameter of axle and the sealing member of axle 7 to flow out, thus reach to save material, reduce into
This, protect environment, put forward large-duty purpose.
