Abstract
The utility model provides a conduction oil of taking rotary seal scalds roller, include outer roll body and establish at the internal inner bag of outer roller, outer roll body both ends are equipped with the roll body spindle nose, the inner bag both ends are equipped with the inner bag spindle nose, be equipped with oil channel in the inner bag spindle nose, roll body spindle nose suit is in the outside of inner bag spindle nose, be equipped with the floating bearing between roll body spindle nose and the inner bag spindle nose, be equipped with quiet sealing mechanism in proper order and move sealing mechanism between the inboard roll body spindle nose of floating bearing and inner bag spindle nose, quiet sealing mechanism is the sealing washer, it includes a seal cover to move sealing mechanism, the seal cover outer wall closely cooperates with the roll body spindle nose, seal cover inner wall and the cooperation of inner bag spindle nose interval, be equipped with when rotatory helicla flute with fluid push back to the internal chamber of outer roller of revealing at the seal cover inner wall. The utility model discloses a rely on the sealing washer to seal when out of work, the rotation that work relied on the seal cover realizes that the motion is sealed, the protection sealing washer with the internal chamber of fluid push back to outer roller of revealing.
Description
Technical field
The utility model relates to a kind of heat transfer oil hot roller, particularly a kind of heat transfer oil hot roller with rotatory sealing.
Background technology
The thermal source of heat transfer oil hot roller is from the conduction oil flowing through cylindrical shell, conduction oil rotates along with outer roll body, the other end is flowed to from one end, continuous circulation, compensate outer roll body dispersed heat, conduction oil enters outer roll body inwall from inner bag spindle nose endoporus, and because outer roll body rotates, inner bag is motionless, conduction oil can flow out from inner bag spindle nose cylindrical and outer roll body spindle nose endoporus junction, needs sealing to work.
General Purpose Rubber sealing ring is mainly due to boiling hot roller rotating speed high (800r/min), conduction oil temperature high (260 DEG C), conduction oil cleannes are very poor, in oil, dust is many, causes ring wear, and structure upper inner-liner spindle nose cylindrical and boiling hot roller shaft head bore concentricity have deviation, also ring wear can be caused, therefore, scalding sealing ring on roller at oil will soon lose efficacy, and caused sealing unsuccessfully.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, the heat transfer oil hot roller of band rotatory sealing.
Technical problem to be solved in the utility model is realized by following technical scheme, the utility model is a kind of heat transfer oil hot roller with rotatory sealing, comprise outer roll body and be located at the inner bag in outer roll body, outer roll body two ends are provided with roll body spindle nose, inner bag two ends are provided with inner bag spindle nose, oil transportation channel is provided with in inner bag spindle nose, roll body spindle nose is sleeved on the outside of inner bag spindle nose, floating bearing is provided with between roll body spindle nose and inner bag spindle nose, be characterized in, roll body spindle nose inside floating bearing and be provided with static seal mechanism and movable sealing mechanism successively between inner bag spindle nose, static seal mechanism is sealing ring, movable sealing mechanism comprises a sealing shroud, sealing shroud outer wall and roll body spindle nose closely cooperate, sealing shroud inwall and inner bag spindle nose interval coordinate, when sealing shroud inwall is provided with rotation, the fluid of leakage is pushed back to the helicla flute of outer roller intracoelomic cavity.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, and the helicla flute of described sealing shroud inwall is provided with 12 roads.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, and described floating bearing is made up of the two dribbling bearings be arranged side by side.
Compared with prior art, the utility model is not when working, rely on sealing ring to seal, during work, rely on the rotation of sealing shroud that the fluid of leakage is pushed back to outer roller intracoelomic cavity, realize motion seal, make high-temperature oil liquid can not flow to sealing ring place, affect the sealing property of sealing ring, extend the service life of sealing ring, structure is simple, provides sealing effectiveness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation of Tu2Shi movable sealing mechanism.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
See figures.1.and.2, a kind of heat transfer oil hot roller with rotatory sealing, comprise outer roll body and be located at the inner bag in outer roll body, outer roll body two ends are provided with roll body spindle nose 3, inner bag two ends are provided with inner bag spindle nose 1, oil transportation channel 2 is provided with in inner bag spindle nose 1, roll body spindle nose 3 is sleeved on the outside of inner bag spindle nose 1, floating bearing 4 is provided with between roll body spindle nose 3 and inner bag spindle nose 1, roll body spindle nose 3 inside floating bearing 4 and be provided with static seal mechanism and movable sealing mechanism successively between inner bag spindle nose 1, static seal mechanism is sealing ring 5, movable sealing mechanism comprises a sealing shroud 6, sealing shroud 6 outer wall and roll body spindle nose 3 closely cooperate, sealing shroud 6 inwall and inner bag spindle nose 1 interval coordinate, when sealing shroud 6 inwall is provided with rotation, the fluid of leakage is pushed back to the helicla flute 7 of outer roller intracoelomic cavity.
The helicla flute 7 of described sealing shroud 6 inwall is provided with 12 roads.
Described floating bearing 4 is made up of the two dribbling bearings be arranged side by side.
Conduction oil enters outer roller intracoelomic cavity from the oil transportation channel 2 in inner bag spindle nose 1, and because outer roll body rotates, inner bag is motionless, and conduction oil can flow out from the junction of inner bag spindle nose 1 with roll body spindle nose 3, needs sealing to work.Under duty, outer roll body rotates, utilize the pressure that outer roll body rotary motion produces, offset the stress that conduction oil leaks, simultaneously, the fluid leaked is pushed by inclined-plane under the effect of helicla flute 7, be back to the inner chamber of outer roll body, carry out motion seal, alleviate the pressure of sealing ring 5, reach the effect of sealing, and sealing shroud 6 adopts polytetrafluoroethylene (PTFE), high temperature resistant, sealing shroud 6 outer wall and roll body spindle nose 3 closely cooperate, sealing shroud 6 inwall and inner bag spindle nose 1 matched in clearance, reduce the concentricity requirement of inner bag spindle nose 1 cylindrical and roll body spindle nose 3 endoporus, polytetrafluoroethylene (PTFE) linear expansion coefficient is high, can Reliable guarantee inner bag spindle nose 1 cylindrical and roll body spindle nose 3 endoporus tight fit.
