Abstract
The utility model discloses a xanthating machine shaft seal device, including main shaft and sealing device, sealing device's structure is, sealing device comprises sealing drum, filler and extruded article, and the left end of sealing drum is equipped with the external screw thread that matches with the screw hole of yellow box right -hand member, and the left end of the barrel of sealing drum and right -hand member are equipped with the backup pad respectively, and the left support plate of sealing drum sinistron, right -hand member and right branch fagging are two and be symmetry setting, wherein are equipped with the screw hole on the left support plate, through the fix with screw on the xanthating machine box, the extruded article be its hole of cylindric and the main shaft matches, its outer peripheral face with sealed cylinder hole matches, and this extruded article right -hand member is equipped with the backup pad of two symmetric distributions, this backup pad be equipped with the screw hole that matches with the bolt with screw hole in the backup pad of sealing drum right -hand member is the same and relative, and the butter packing is filled the sealing drum with in the cavity between the main shaft. The utility model has the advantages of sealed reliable and long service life.
Description
Technical field:
The utility model relates to a kind of sealing technique, particularly a kind of xanthating machine main shaft sealing device.
Background technique:
Existing xanthating machine main shaft sealing construction is O type sealing configuration, and this O RunddichtringO structure is easy to wear, and life-span short-range missile causes carbon sulfide seepage, and yellow workshop harmful gas concentration exceeds standard, and the replacement o seal ring viscose glue that need stop production is scrapped.
Summary of the invention:
The utility model object is to provide and a kind ofly seals advantage that is reliable, long service life.
The technical solution of the utility model is, a kind of xanthating machine main shaft sealing device, comprise main shaft and seal arrangement, it is characterized in that: the structure of described seal arrangement is, described seal arrangement is by sealing drum, filler and extrusion composition, the left end of described sealing drum is provided with the outside thread with the corresponding threaded holes of yellow casing right-hand member, left end and the right-hand member of the cylindrical shell of described sealing drum are respectively equipped with dunnage, described sealed cylinder is left, left support plate and the right support plate of right-hand member are two and are symmetrical set, wherein left support plate is provided with tapped hole, be fixed by screws on xanthating machine casing, described extrusion is that its endoporus of tubular and described main shaft match, its outer circumferential face and described sealing bore match, this extrusion right-hand member is provided with two symmetrical dunnages, the tapped hole that this dunnage is provided with in the dunnage of tapped hole and the described sealing drum right-hand member matched with bolt is identical and relative, butter packing is filled in the cavity between described sealing drum and described main shaft.
The utility model has the advantage sealing reliable and long service life compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, the utility model has following technical proposals to be, a seal arrangement is provided with between main shaft 6 and casing, described seal arrangement is by sealing drum 1, filler 5 and extrusion 2 form, the left end of described sealing drum is provided with the outside thread with the corresponding threaded holes of headstock right-hand member, left end and the right-hand member of the cylindrical shell of described sealing drum are respectively equipped with dunnage, described sealed cylinder is left, left support plate and the right support plate of right-hand member are symmetrically arranged dunnage, wherein left support plate is provided with tapped hole, be fixed on xanthating machine casing by screw 3, described extrusion is tubular, its endoporus and described main shaft match, its outer circumferential face and described sealing bore match, this extrusion right-hand member is provided with two symmetrical dunnages, this dunnage is provided with identical with the tapped hole in the dunnage of the tapped hole that bolt 4 matches and described sealing drum right-hand member and relatively, butter packing 5 is filled in the cavity between described sealing drum and described main shaft.
Sealing principle of the present utility model, makes extrusion be moved to the left by swivel bolt, makes butter packing produce distortion, form sealing, after equipment operation certain hour, after the wearing and tearing of butter packing, sealing effect declines, should immediately butter packing be made to produce distortion further by bolt, because the volume of packing is comparatively large, thus service time is very long, and changing butter packing can be undertaken by when coming overhaul of the equipments, thus, can not occur because seal failure causes stopping production.
