Abstract
The utility model relates to an oil filling sealing device for a rubber-plastic pressurizing turnover internal mixer. The sealing device comprises a fixed sealing ring, a rotary sealing ring and a sealing sleeve, wherein the rotary sealing ring is arranged at the end of a rotor shaft of a turnover feed box, the fixed sealing ring is arranged between the rotary sealing ring and the sealing sleeve, and the sealing sleeve includes an inner sealing sleeve and an outer sealing sleeve. The outer sealing sleeve is sleeved on the inner sealing sleeve and mounted on a flange base; the inner sealing sleeve is sleeved on the rotor shaft of the turnover feed box; an oil pipe is arranged in the inner sealing sleeve; and one end of the oil pipe penetrates through the inner sealing sleeve to the end face of the rotary sealing ring. Oil is supplied for the fixed sealing ring and the rotary sealing ring by the oil pipe, excessive friction between the fixed sealing ring and the rotary sealing ring is avoided, energy consumption is reduced greatly, and the service life of the sealing device is long. Simultaneously, as the oil is capable of softening rubber to form an oil film, powder leakage is stopped, and energy conservation and environmental protection are realized. Moreover, owing to stoppage of powder leakage, mixed rubber with fine quality is stable.
Description
Technical field
The utility model relates to a kind of rubber and plastic convertible masticator that pressurizes, and specifically, relates to the pressurize sealing device of convertible banbury of a kind of rubber and plastic.
Background technology
At present, rubber and plastic pressurizes both at home and abroad, and (the sealing effectiveness difference is called masticator to convertible masticator, good sealing effect is called banbury) sealing device all adopt end face contact friction formula banburying device, this device by cover in standstill seal ring, rotating ring, hermetically sealed case, the sealing, regulate screw mandrel and clearance compensating spring etc. and form.Utilize the effect of regulating screw mandrel and counterbalance spring compression stress during work, impel sealing inner sleeve press seal ring and rotor axle head rotating ring face to fit and rub, to reach sealing effectiveness.This sealing device in process of production, because of medium, viscosity difference, lubricated relatively poor, cause end-face friction overheated, also bigger because of frictional force, static and dynamic sealing circumpolar generation easy to wear space, in case produce the gap, sizing material overflows from the gap under pressure, not only cause the rubber proportion raw material to run off, cause influencing the rubber-plastics material performance after the refining, and contaminated environment, the operator brings injury to masticator.Simultaneously later reparation is increased cost and difficulty.In addition, entering the middle sizing material hardness in 3-5 hour of static and dynamic sealing ring becomes as steel plate, be difficult to make the cooperation of dynamic and static ring to return to original state, its structure is to leak glue more to immerse more, it is big more to immerse the end clearance more, and tight more spring is leaked in big more leakage more more, cause bigger wearing and tearing, reduction of service life and waste more electric energy.
The utility model content
The purpose of this utility model is at existing rubber and plastic poor, the above-mentioned deficiencies such as wearing and tearing are big, wastage of material, contaminated environment of sealing effectiveness that convertible masticator exists of pressurizeing, a kind of simple in structure, good sealing effect, energy-conserving and environment-protective be provided, do not leak powder, the sizing material that the refines stable rubber and plastic of fine quality convertible banbury oil-filling type sealing device that pressurizes.
The technical solution of the utility model is: a kind of oil filling sealing device for rubber-plastic pressurizing turnover internal mixer, the sealing device comprises stationary seal ring, rotating seal ring and sealing shroud, rotating seal ring is arranged on the axle head of upset hopper armature spindle, stationary seal ring is arranged between rotating seal ring and the sealing shroud, described sealing shroud comprises sealing inner sleeve and hermetically sealed case, hermetically sealed case is sleeved in the sealing and puts, and is installed on the flange seat, and the sealing inner sleeve is sleeved on the armature spindle of upset hopper; Be provided with oil pipe in the described sealing inner sleeve, an end of oil pipe passes the sealing inner sleeve to the end face of rotating seal ring;
Preferably, described sealing device also is provided with clearance compensating spring and regulates screw mandrel, and an end of sealing inner sleeve contacts with rotating ring by stationary seal ring, and the other end joins by clearance compensating spring and adjusting screw mandrel;
Preferably, leave the gap between the end that is connected with clearance compensating spring of described sealing inner sleeve and the hermetically sealed case;
Preferably, be provided with oil pipe in the described hermetically sealed case, an end of oil pipe passes hermetically sealed case to the end face of rotating seal ring;
Preferably, described sealing inner sleeve and hermetically sealed case are fixedly mounted on the flange seat, leave the gap between sealing inner sleeve and the sealing rotary change.
The beneficial effects of the utility model are: the utility model is simple in structure, good sealing effect, saving cost.To stationary seal ring and rotating seal ring fuel feeding, avoid the excessive friction between stationary seal ring and the rotating seal ring by oil pipe, greatly cut down the consumption of energy long service life.Simultaneously, because oil can softened rubber, make it to form oil film, stop and leak powder, energy-conserving and environment-protective, and owing to stop and leak powder, stablize so that institute's sizing material that refines is of fine quality.
