Description
Technical field:
The utility model belongs to rubber equipment technical field of sealing technology, relates to a kind of novel closed-smelting machine rotor seal arrangement, magnetic medium sealing technique is applied in closed-smelting machine rotor sealing, effectively improves sealing effect.
Background technique:
Now, the production of elastomeric compound mainly adopts banbury to carry out, in banbury by matrix glue and compounding ingredient and particulate additives is dispersed and mixing, it is a kind of compounding process efficiently, and the gap of banbury operationally between the rotor diameter of axle and banburying chamber's sidewall easily makes above-mentioned compounding ingredient reveal, to such an extent as to affect the mixed effect of matrix glue and compounding ingredient; In order to stop the generation of leaking material phenomenon, originally the composition of trickle easy distribution is adhered to by oil film and processes by people, but because banburying chamber's internal pressure is higher, the paste that bonding is formed slowly can be extruded along rotor shaft, so people add seal ring at the two ends of rotor shaft again, be gradually improved again afterwards.At present, on rubber internal mixer, the main seal arrangement adopted has following four kinds: end face seal, labyrinth seal, left-hand thread sealing and packing seal, but all there is more shortcoming in these four kinds of sealing means: wherein the most frequently used face seals there will be sealing effect decline phenomenon after banbury runs a period of time, this is because banbury operationally hold-down ring cannot immediately following the play of swivel becket on rotor, thus produce gap and fine material inserted cause end face seal not tight; In use for some time, in concavo-convex ring, powder compounding ingredient can cumulatively finally cause leaking in labyrinth seal; Although compounding ingredient top can be got back in banburying chamber by left-hand thread sealing under the effect of axial force, after long-time use, left-hand thread there will be wearing and tearing, still cannot realize permanent sealing; Although stuffing seal structure is simple, easy to use, take gland filler-changeable apart, filler wearing and tearing are severe, the life-span is not long, need often change, and only have the effect when material is subject to middle pressure just better.
Such as there is a kind of closed-smelting machine rotor shaft sealer disclosed in Chinese patent 201220389263.2, it tightens to be sticked at closed-smelting machine rotor axle and is equipped with the elastic resin seal ring that end face is respectively concave surface and convex surface, by the special splayed shape structure that elastic resin seal ring is formed, the elastic resin seal ring when rotor shaft rotates still is close on rotor shaft outer surface to increase sealing area; Chinese patent 201210487263.0 is separately had to disclose a kind of device for sealing rotor shaft of mixing roll, it establishes seal ring, sealing inner sleeve and hermetically sealed case in the outer ring of rotor, single unit system adopts bronze skeleton, filled polytetrafluoroethylene in seal ring, and is provided with the selflubricating of adjustable spring pressurization section; Separately there is Chinese patent 200920294709.1 to disclose and be a kind ofly arranged on the device for sealing rotor shaft of mixing roll that rotor shaft exposes the axle journal cylindrical of the mixing groove of Mixing roll, axle sleeve is fixed on the mixing groove of Mixing roll, end face sealing ring and gland are actively installed between inner hole of shaft sleeve and axle journal cylindrical, end face sealing ring is adjacent to all the time on the rotor shaft raised head face at axle journal place under the effect of top pressure spring, axle journal cylindrical be provided with rotatably be connected by the radial seal ring of polytetrafluoroethylmaterial material matter; Although above-mentioned seal arrangement can achieve good sealing effect to a certain extent, but easily there is plastic deformation and cause compounding ingredient to leak, admittedly cannot permanently effectively prevent powder in rotor shaft working procedure from leaking outside in material therefor teflon under continuous load effect.
Summary of the invention:
The purpose of this utility model is the shortcoming overcoming prior art existence, seeks design and provides a kind of novel closed-smelting machine rotor seal arrangement, better can improve the banburying effect of banbury, ensures that material proportion is consistent.
To achieve these goals, what the closed-smelting machine rotor seal arrangement that the utility model relates to was integrally provided in banburying chamber exposes on rotor shaft, its agent structure comprises threaded sleeve, No. I pole shoe, permanent magnet, shell, No. II pole shoe, end cap, No. I sealed cover, No. I O RunddichtringO, cooling duct, No. II O RunddichtringO, No. II sealed cover, end flanges, fastening flange, magnetic medium, liquid entering hole and liquid outlet, wherein No. I pole shoe, No. II pole shoe and shell are symmetrical split type structure, threaded sleeve is socketed on rotor shaft by screw fixing compact, the one end being wrapped in the shell on threaded sleeve is fixedly connected on the outer wall of banburying chamber by screw, the other end of shell is fixing to being connected to end cap by screw, the internal chamber wall of shell is bolted No. I pole shoe and No. II pole shoe, the fixedly embedded formula in interval between No. I pole shoe and No. II pole shoe lays permanent magnet, shell inner cavity wall and No. I pole shoe adjoiner are fixedly installed No. II O RunddichtringO, shell inner cavity wall and No. II pole shoe adjoiner are fixedly installed No. I O RunddichtringO, are fixedly filled with magnetic medium in No. I pole shoe and the gap between No. II pole shoe and threaded sleeve outer wall, in the inner chamber of shell, surrounding type is provided with the cooling duct of U-shaped structure, liquid entering hole and liquid outlet is offered respectively at the two ends of cooling duct, on the cooling duct of shell and banburying chamber's outer wall connecting end, seal weld is connected to No. II sealed cover to prevent cooling liquid seepage, on the cooling duct of shell and end cap butt end, seal weld is connected to No. I sealed cover to prevent cooling liquid seepage, and the periphery of shell is fixedly welded with end flanges and fastening flange.
The utility model compared with prior art, solve the permanent problem using rear wearing and tearing leakage material in conventional seals mode, magnetic medium sealing is fused in banbury sealing, permanent magnet poles and pole shoe is utilized to coordinate to form magnetic force, and labyrinth sealing is dissolved in magnetic medium sealing, axle sleeve is arranged to helical screw thread axle sleeve to form back pressure when rotating, the compounding ingredient major part making to leak out from gap is sent back in banburying chamber under the double action of magnetic force and back pressure, residual fraction merges in magnetic medium, and can by realizing the real-time adjustment of sealing load to the adjustment of rotor speed, indirectly make compounding ingredient more fully mix with matrix glue, ensure that the consumption of compounding ingredient in producing or testing, improve the quality of glue product, in maintenance, magnetic medium sealing is less than the maintenance of contact seal such as mechanical seal, packing seal, oil sealing etc., and can not cause any wear-out failure to rotor shaft, this apparatus structure is simple, scientific in principle, novel in design, workable, good sealing effect, long service life, and maintenance cost is low, and working environment is friendly.
