Abstract
The utility model provides a sealing device of a horizontal roll mill, comprising a bolt 1, a flange 2, a connecting ring, a baffle 2, a baffle 1, a flange 1, a bolt 2 and a taper sleeve. The flange 2, the baffle 2 and the connecting ring are welded into a whole and are connected and fixed on an end cover by the bolt 1, so as to form a gasket-type sealing element. The connecting ring is an irregular ring-shaped structure which is sealed at the upper part and ringent at the lower part. The flange 1 is welded on hemipyramid sleeves, and two hemipyramid sleeves are integrated together by the bolt 2 to form the taper sleeve which is fixed on a compression roller; the baffle 1 is welded on the taper sleeve and forms a movable sealing element together with the taper sleeve to rotate along with the compression roller. The rotary baffle 1 and the static baffle 2 form an active and static sealing structure; when the object reaches a certain height, the object can be leaked back in a main body from the lower part of the connecting ring along with the rotary compression roller, thereby effectively preventing the material from overflowing. The sealing device has simple and reliable structure, combines static and dynamic as well as achieves good sealing effect.
Description
Technical field
Novel a kind of seal arrangement, the seal arrangement between particularly a kind of roller mill pressure roller for sleeping in and the end cap of relating to of this use.
Background technique
Sealing commonly used at present is with V-type seal with elastometic washer or labyrinth seal, but because this class sealing configuration is simple, sealability is relatively poor, generally only is applicable to static sealing.In roller mill for sleeping in, end cap is passed at the pressure roller two ends, exerts pressure to material by oil hydraulic cylinder, through repeatedly pushing material is pulverized.Because there is certain clearance pressure roller and end cap contacting point, has partial material at material in by pressure roller extruding, material and material mutual extrusion process and splash away by the gap on the end cap.So adopt this simple in structure, seal arrangement that sealability is relatively poor, can not satisfy the seal request that crouches between the roller mill sound rotational structure spare far away, easily cause excessive, the outside dust invasion of materials inside, befouling environment etc.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provides a kind of seal arrangement that is used for crouching between the roller mill sound rotational structure spare, and it can not only effectively control material from leakage, guarantees sealing, and simple in structure, reliable.
The technological scheme that its technical problem that solves the utility model adopts comprises bolt one, flange two, connecting ring, baffle plate two, baffle plate one, flange one, bolt two, tapered sleeve.Flange two, baffle plate two and connecting ring are welded into an integral body, are fastened on the end cap by bolt one, form static seal.Connecting ring adopts the irregular loop configuration that goes up the sealing under shed.Flange one is welded in half cone and puts, and two half cone covers lump together the formation tapered sleeve by bolt two and are fixed on the pressure roller, and baffle plate one is welded on the tapered sleeve, forms dynamic seal with tapered sleeve, rotates with pressure roller.The baffle plate one of rotation and static baffle plate two form the static and dynamic sealing structure, after material reaches certain height, will drain back in the cylindrical shell from the connecting ring bottom along with the pressure roller of rotation, thereby effectively stop overflowing of material.
The beneficial effects of the utility model are: successfully solved problems such as excessive, the outside dust invasion of materials inside that the sealing of roller for sleeping in mill sound rotational structure spare exists, befouling environment.Be association of activity and inertia, reach good sealing effect.
Description of drawings
The utility model is described in further detail below in conjunction with Figure of description and embodiment.
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1: 1. bolt one, 2. end cap, 3. flange two, 4. connecting ring, 5. baffle plate one, 6. baffle plate two, 7. flange one, 8. bolt two, 9. tapered sleeve, 10. pressure roller.
Specific implementation method
As shown in Figure 1, flange 23, baffle plate 26 and connecting ring 4 are integrally welded, are connected on the static end cap 2 by bolt 1, form the static seal body.Flange 1 is welded in half cone and puts, and two half cone covers lump together formation tapered sleeve 9 by bolt 28 and are fixed on the pressure roller 10, and baffle plate 1 is welded on the tapered sleeve 9, forms dynamic seals with tapered sleeve 9, rotates with pressure roller 10.Crouch the roller mill when work, drive pressure roller 10 at the effect lower cylinder body of frictional force and rotate together.In the process that material is pulverized, left, at first the baffle plate in the motive sealing 26 material that part can be splashed keep off back, and next is worked as material and partly passes baffle plate 26, and when being between baffle plate 1 and the baffle plate 26, baffle plate 1 plays a role, permission solid accumulation certain height.Simultaneously connecting ring 4 adopts the irregular loop configuration that goes up the sealing under shed, and the material of accumulation spills from connecting ring 4 bottoms under the centrifugal action of dynamic seal rotation, continues to get back to the inside of cylindrical shell and pulverizes, leaves process.All the time there is the moving material curtain of one deck to form in the working procedure between baffle plate 1 and the baffle plate 2, can effectively stops outside dust invasion, keep clean environment.
Particularity when the suitable roller grinder that crouches of this kind sealing is done is association of activity and inertia, and outwards splashing of twice effective prevention material reaches good sealing effect.
Claims (2)
1. the seal arrangement that the roller that crouches grinds, comprise bolt one, flange two, connecting ring, baffle plate two, baffle plate one, flange one, bolt two, tapered sleeve, it is characterized in that: flange two, baffle plate two and connecting ring are welded into an integral body, are fastened on transfixion on the end cap by bolt one; Flange one is welded in half cone and puts, and two half cone covers lump together the formation tapered sleeve by bolt two and are fixed on the pressure roller, and baffle plate one is welded on the tapered sleeve and rotates with pressure roller.
2. according to the seal arrangement of the described roller mill for sleeping in of claim 1, it is characterized in that: described connecting ring is the irregular loop configuration that goes up the sealing under shed.
