Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
Reactor sealing device as shown in Figure 1, including kettle 2, agitating shaft 1, housing 3, the first stationary ring 4, the first rotating ring
5th, the second stationary ring 6, the second rotating ring 7 and connection ring 8, agitating shaft 1 stretch into the inside of kettle 2 and are articulated in kettle 2, and housing 3 is fixed in
Kettle 2, agitating shaft 1 runs through housing 3, and the first stationary ring 4, the second stationary ring 6 are fixed in the inside of housing 3 and rotatably covered
Loaded on agitating shaft 1；First rotating ring 5, the second rotating ring 7 and connection ring 8 are fixed in agitating shaft 1 and quiet positioned at the first stationary ring 4, second
Between ring 6；The surface of first stationary ring 4 is contacted with the surface of the first rotating ring 5, and the first rotating ring 5 rotates relative to the first stationary ring 4；Second
The surface of stationary ring 6 is contacted with the surface of the second rotating ring 7, and the second rotating ring 7 rotates relative to the second stationary ring 6；The inside of housing 3 has chamber
Cooling medium is filled with body, cavity.
Reactor is applied to the production of the product such as fine chemistry industry, cosmetics, pharmaceutical industry, and the present embodiment is to produce cosmetics
Material exemplified by illustrate.Agitating shaft 1 rotates at a high speed in a kettle., carries out the stirring of raw material, what agitating shaft 1 rotated at a high speed
During inevitably the raw material that is rolled up in the kettle that reacts spilt along the space between agitating shaft 1 and kettle 2.In order to prevent
Raw material is spilt, and is entered also for impurity particles such as the dusts prevented in outside air in reactor, in kettle 2 and the knot of agitating shaft 1
Sealing device is set at conjunction.
Housing 3 is fixed on kettle 2 in bolted mode, and agitating shaft 1 rotates at a high speed, thus drive the first rotating ring 5,
Second rotating ring 7 and connection ring 8 are rotated at a high speed, and the surface of the first stationary ring 4 is contacted with the surface of the first rotating ring 5, when the first rotating ring 5 relative to
, can be by the seam between the surface of the first rotating ring 5 and the surface of the first stationary ring 4 by the friction on two surfaces when first stationary ring 4 rotates at a high speed
Gap is closed, in this way, just being closed extraneous with isolation inside reactor, prevents introduced contaminants between agitating shaft 1 and kettle 2
Space enters in reactor；
The surface of second stationary ring 6 is contacted with the surface of the second rotating ring 7, when the second rotating ring 7 rotates at a high speed relative to the second stationary ring 6
When, can be by the gap closing between the surface of the second rotating ring 7 and the surface of the second stationary ring 6, in this way, just will be anti-by the friction on two surfaces
The closing that is hedged off from the outer world inside kettle is answered, prevents space of the raw material liq in reactor between agitating shaft 1 and kettle 2 from splashing
Go out；
Because the surface of the first rotating ring 5 rotates relative to the surface of the first stationary ring 4, the surface of the second rotating ring 7 is relative to second
The surface of stationary ring 6 rotates, then two surfaces of the friction that contacts with each other inherently discharge amount of heat, if not to the first rotating ring
5th, if the first stationary ring 4 and the second rotating ring 7, the second stationary ring 6 are cooled, seal failure will necessarily be caused, the present apparatus passes through
Cavity is set inside housing 3, and fills cooling medium, cooling medium by absorbing amount of heat, can to the first stationary ring 4,

Further, the cooling liquid inlet 31 connected in the cavity, opposite side is provided with the cooling with being connected in the cavity
Liquid outlet 32.In this way, the cooling medium in cavity just can be changed at any time, it is cold in cavity when the reactor working time is longer
But the temperature of medium can gradually rise, can be and warm by the relatively low cooling medium of temperature from cooling liquid inlet 31 inputs cavity
The higher cooling medium of degree then flows out from cooling liquid outlet 32, carries out cooling processing, just can so realize following for cooling medium
Ring, can make the cooling medium in cavity be in low-temperature condition all the time, to the good cooling effect of sealing device.
Further, the cooling medium is water, and the specific heat capacity of water is larger, and heat absorption capacity is strong, and cost is low in addition.
Further, the reactor sealing device also includes positioning bearing 9, and the outer ring of positioning bearing 9 is fixed in housing 3, stirred
Mix the inner ring that axle 1 is fixed on positioning bearing 9.Agitating shaft 1 is fixed on housing 3 by positioning bearing 9, is easy to the installation of agitating shaft 1,
The swing for being also prevented from agitating shaft 1 simultaneously damages sealing device.
Further, the first stationary ring 4, the material of the second stationary ring 6 are graphite, and graphite material is wear-resisting, and the first stationary ring 4, second is quiet
Ring 6 is manufactured using graphite, and its abrasive resistance is strong, can increase the service life, and reduces use cost.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
