Description
Technical field:
The utility model relates to the Sealing Technology of rubber and plastic banbury, specifically a kind of banbury bearing block face seals, and it can effectively prolong the working life of rotor bearing and then improve the reliable operation performance of banbury.
Background technology:
We know; So-called banbury be in the banburying chamber of sealing by rotor to sizing material plasticate, the special-purpose rubber preparing device of kneading processing such as mixing and heat refining; It is compared with mill, has the production efficiency height, refining colloid amount is good, dust pollution is less and can obviously improve working environment, alleviate the outstanding advantage of labor strength.Therefore, it has become rubber industry and after eliminating the mill that falls behind gradually, has optimized first-selected a kind of main rubber preparing device.But; Need not to dare not or would not speak up; Just refine particular job environment of glue manufacturing enterprise; Even adopting advanced banbury equipment to refine in the production environment of glue operation, also still have the phenomenon that some sizing material particle dusts pollute inevitably, these sizing material particle dusts also can constitute the working life of polluting and then influencing bearing to bearing block.Particularly in refining glue operation process; Some hot gluse sizes in the banburying chamber slowly flow out from the end face seal of rotor journal easily constantly; Though hot gluse size negligible amounts along the rotor journal outflow; But direct inner side end and the continuation of polluting bearing block of these hot gluse sizes meetings pollutes damage along axle journal intrusion bearing block inside to the rotor bearing that props up bearing load, will cause bearing sharply to wear and tear when serious and the acceleration inefficacy.This is because due to the structural defect that the bearing block of banbury exists in the end face seal design.According to investigation: the bearing block of existing banbury mostly is the conventional seals structure that adopts equipped rubber oil sea and felt sealing ring in the seal cover; In fact; The seal of this routine only has the effect that prevents that lubricating oil from leaking outside and stoping the slight dust of general environment to be invaded; And in the production environment of the refining glue enterprise of heavy contamination, it just can't stop that sizing material dust particle foreign material get into bearing block inside bearing is formed direct abrasive action, and this will shorten the service life of bearing greatly.And the vitals of bearing to be a bearing load rotor carry out in banbury kneading operations since the life-span of bearing because of micelle directly wearing and tearing shortens with regard to the bearing that changes the outfit of shutdown maintenance continually, this will have a strong impact on the continuation of production operation.This is the main cause that existing banbury production efficiency is lower, the operating maintenance cost is higher, is that banbury needs further to improve and perfect places, this also just the utility model want the problem that solves.
The utility model content:
The purpose of the utility model is intended to overcome the weak point that the bearing block of existing banbury exists on hermetically-sealed construction; A kind of banbury bearing block face seals with high sealing property is proposed; It can stop fully that sizing material dust particle foreign material intrusion bearing block is inner and safeguard the good working environment that cleans of bearing, can prolong the service life of bearing effectively.
The banbury bearing block face seals that the utility model proposes is realized through following technical scheme: it comprises sealing shroud, sealing ring and is fitted to seal cover, the rubber oil sea in the bearing block; It is characterized in that: said sealing shroud is installed on the closed-smelting machine rotor axle; The sliding supporting sealing shroud that is loaded on of seal cover; The rubber oil sea and the sealing shroud outer round surface that are fitted in the seal cover constitute hermetically-sealed construction; Sealing shroud is provided with the spill annular groove; Said sealing ring is flush-mounted in the spill annular groove of sealing shroud, and the bearing pin cunning that is installed on diapire in the spill annular groove is assigned in the pin-and-hole of sealing ring, and the one group of spring-loaded sealing ring that is fitted in the spill annular groove is close to seal cover side formation end face seal structure.It is performed such equipped use: it is in bearing block, to keep on the basis that is equipped with rubber oil sea and felt sealing ring in original seal cover; On the closed-smelting machine rotor axle of bearing block inboard, fixedly mount sealing shroud again and make sealing shroud along with armature spindle together rotates; Sealing shroud can stop the hot gluse size that flows out along axle journal to get in the bearing block effectively; Be fitted to seal cover in the bearing block and be and slidingly supportingly be loaded on the sealing shroud and form movable sealing structure by the sealing shroud of felt sealing ring, rubber oil sea and rotation; Being flush-mounted in sealing ring in the spill annular groove will be driven together by bearing pin and rotate with sealing shroud; Simultaneously; One group of spring-loaded sealing ring and the outer face that makes sealing ring tightly pressing form dynamic end face seal structure in the side of seal cover, even occur under the situation of wearing and tearing at sealing ring, have high sealing property because the automatic compensating action of one group of spring also can be kept end face seal structure.Make it can stop that fully the sizing material particle dust intrusion bearing block that fills the air in refining glue operating environment is inner; Can prevent effectively that bearing from polluting; Safeguard the working environment of the good cleaning of bearing, can greatly prolong the operate as normal life-span of bearing and then guarantee the duration performance of banbury production operation.
The utility model also has following technical characterictic:
Be uniformly distributed with at the inner face of sealing ring and be provided with eight; Or ten location hole of the spring be symmetrical set two pin-and-holes; The supporting leading portion of one group of spring places in the location hole of the spring of sealing ring; Pressing is in the side of seal cover more reposefully in the outer face that this structural design can make sealing ring, and this has positive effect to automatic compensating action that improves sealing ring and the tightness that strengthens end face seal structure.
Said bearing pin is to adopt interference to be tightly fixed to be installed on the interior diapire of spill annular groove, and this simple and direct structural design is convenient to the equipped operation of bearing pin and can drives sealing ring easily together rotate with sealing shroud especially.
Said sealing shroud is to be fixedly installed on the closed-smelting machine rotor shaft neck by screw, makes sealing
The assembly operation of cover is very convenient and have a good fixed performance.
Form static seal structure at equipped O RunddichtringO of the spill annular groove inwall of sealing shroud and sealing ring outer round surface, this structural design can prevent can further improve sealing property in the spill annular groove of dust intrusion sealing shroud effectively.
Form movable sealing structure at equipped felt sealing ring of seal cover inwall and sealing shroud outer round surface, can prevent the interior lubricating oil of the bearing block absorption dust that leaks outside effectively, this also has certain effect to further raising sealing property.
The utility model is compared with the Sealing Technology of existing banbury and is had following outstanding advantage and progress:
The utility model has been initiated " being flush-mounted in the end face seal structure that sealing ring and seal cover side in the sealing shroud spill annular groove constitute bearing block by one group of spring-loaded "; It utilizes the automatic compensating action of spring can keep end face seal structure long-term effectively to have high sealing property; Can thoroughly stop the sizing material particle dust intrusion bearing block internal contamination bearing in the production of refining glue; Can safeguard the working environment of bearing cleaning effectively, this is to prolonging the bearing working life-span and then guaranteeing that the continuation of banbury production operation all has positive effect.
