Description
Technical field
It the utility model is related to internal rubber mixer technical field, more particularly to a kind of mixer sealing structure of shaft end.
Background technology
Existing mixer shaft end seal generally mainly holds surface seal structure level with both hands using bakelite sealing ring and armature spindle,
This structure is fairly simple, but sealing reliability is poor, and powder easily enters seal interface, especially in seal wears or close
When seal ring is equipped with gap with rotor axial end, powder will be leaked and all the more seriously can leak the standard that powder not only have impact on sizing compound formula
True property, and since dust from flying environmental pollution is larger, simultaneously because the unlubricated medium of sealing surface, sealing ring are easy to wear.
Utility model content
The purpose of this utility model is to provide a kind of mixer sealing structure of shaft end, and solving sealing of the prior art can
Poor by property, leakage powder is serious, the short-life technical problem of sealing ring.
A kind of outer wall of mixer sealing structure of shaft end, including rotor and banburying chamber, the rotor shaft end and banburying chamber it
Between be disposed with metal pressure ring and sealing ring, the sealing ring outer edge surface opposite with metal pressure ring is the conical surface.
Based on the above technical solutions, the utility model can also do following improvement：
Further, the sealing ring is metallic packing ring, and is additionally provided with gold between the sealing ring and rotor shaft end
Belong to insert, the beneficial effect using this step is to improve wearability by metal insert, is prolonged the service life.
Further, the metal insert side offers cone tank, the conical surface of the sealing ring and the cone of metal insert
Shape groove is corresponding, and the beneficial effect using this step is cooperated using cone tank and the conical surface, changes plane of the prior art
Assembling form, can reduce powder leakage.
Further, the angle of the cone tank is 60-150 °.
Further, the conical surface end of the sealing ring is plane or arc surface, and the conical surface end of sealing ring and institute
Cavity is formed on the bottom for stating cone tank, and the beneficial effect using this step is to form sealing and oil leab using cavity, is risen at the same time
To sealing and the effect of lubrication.
Further, the first oil filler point is offered inside the first half of the sealing ring, is opened up inside the metal pressure ring
There is the second oil filler point, described first oil filler point one end is connected with second oil filler point, and the other end is connected with the cavity,
Beneficial effect using this step is can be flowed into by drip pump toward oiling inside the second oil filler point, oil by the first oil filler point
Cavity, forms sealing oil duct.
The beneficial effects of the utility model：
The utility model is a kind of mixer sealing structure of shaft end, and original plane sealing structure is changed to conical surface seal knot
Structure, so can effectively prevent the powder in banburying chamber from entering sealing surface, and matching requirements are low；The utility model is in sealing ring
On offer the first oil filler point, utilize and the assembling of metal insert after the oil duct that builds of cavity that is formed at cone angle, Neng Goubao
Card contact surface has lubrication, and friction is small, low in energy consumption, service life length, and plays the role of oil seal, even if using for a long time,
Seal wears, sealing surface gap become larger, and a small amount of powder into gap can only also be flowed out with lubricating oil in slurry, will not
There is dust from flying, sealed reliable, the utility model sealing reliability is high, can effectively extend sealing ring service life, and assemble
It is it is required that low.
