Description
Technical field
The utility model is related to banbury technical field, specially a kind of closed-smelting machine rotor shaft sealing device.
Background technology
Banbury is widely used a kind of mixing facilities of high-intensity clearance in rubber industry, be mainly used in rubber or
The mixing of plastics and compounding ingredient, it can also be used to which rubber or plastics are plasticated.It is main by banburying chamber, rotor, rotor seals plus
Expect that the part such as material pressing device, device for discharging, transmission device and support is constituted.When banbury works, two rotors are relative to turn round, extruding
With material of the shearing from charging material pressing device（Graininess）, the temperature of material is increased, viscosity reduction, add material with
The wettability on mixture surface, makes material fully be contacted with compounding ingredient surface.Meanwhile, the fin on rotor makes axle of the material along rotor
To motion, stirring immixture is played, compounding ingredient is well mixed in material.Banbury carry out milling work when, due to
Banbury is closed, therefore its loss of material, than mill much less, the pollution to environment is also considerably reduced.However, due to close
The mill course of work is in high pressure conditions, and rotor and rotating shaft are kept in motion, and material still can be from stationary seal ring and rotor
Gap leakage between gap between gap, rotating shaft and moving sealing ring and moving sealing ring and stationary seal ring between end face
Outside to banbury.In this way, not only causing wastage of material, machine pressure release is also further resulted in, so as to reduce processing efficiency.
Utility model content
The purpose of this utility model is to provide a kind of good sealing effect, prevents that the closed-smelting machine rotor rotating shaft of material from leakage is close
Seal apparatus, sealing effectiveness and service life are improved to reduce sealing wear.
To achieve the above object, the utility model provides following technical scheme：Closed-smelting machine rotor shaft sealing device, including
Axle bed with through hole, the rotor being arranged in through hole and the rotating shaft being connected with one end face of rotor, in addition to from left to right according to
Secondary phase ground connection is located at rotary packing ring, stationary seal ring and gland between through hole and rotating shaft, the end face that the rotor is connected with rotating shaft
Provided with one week groove, the rotary packing ring part was embedded in the groove, and the stationary seal ring is threadedly connected to through-hole wall,
The gland is secured by bolts on axle bed, and the stationary seal ring runs through with the oil duct that is connected, oil duct is additionally provided with gland
Stationary seal ring.
Further, the end that the stationary seal ring connects with gland is provided with sealing ring.
Further, the profit oilhole being connected with oil duct is additionally provided with the internal chamber wall of the stationary seal ring.
Compared with prior art, the beneficial effects of the utility model are：Closed-smelting machine rotor shaft sealing device is installed on
When being worked on banbury, rotary packing ring and stationary seal ring formation end face seal, when rotating shaft is operated, rotary packing ring turns with rotating shaft
It is dynamic, stationary seal ring remains stationary and it is glanded and presses to rotary packing ring, forms the dynamic sealing of end face laminating, rotary packing ring, which is placed in, to be turned
The material particles for being directly entered gap can be substantially reduced in the groove of son, abrasion is reduced, and hydraulic oil, high pressure are injected by oil duct
Oil can form paste shape body with mixing peptization thing, and can play prevents powder leakage effects, and stationary seal ring and rotary packing ring it
Between, can also form oil film between stationary seal ring and rotating shaft and be lubricated, can prevent abrasion can also prevent leakage, so as to improve close
Sealing property improves device service life.
