Description
Technical field
The utility model relates to a kind of sealing devices, more particularly to a kind of reaction kettle sealing device.
Background technique
In the production process of modernization, reaction kettle is widely used in petroleum, chemical industry, rubber, pesticide, dyestuff, medicine, food
Product, for completing the technical process such as vulcanization, nitrification, hydrogenation, hydrocarbonylation, polymerization, condensation, the once generation leakage of reaction kettle will shadow
Product quality is rung, pollutes environment, or even personal injury is generated to operator, therefore the sealing performance of reaction kettle is entirely to react
The technical guarantee that kettle works normally.
Currently, generalling use the sealing means of packing seal and mechanical seal in reaction kettle, both sealing means are universal
The problems such as in the presence of poor sealing effect in a high voltage state, easy leakage, service life is short, and replacement cost is high, influences reaction efficiency.
Summary of the invention
The utility model is directed to the generally existing poor sealing effect in a high voltage state of sealing means of existing reaction kettle, is easy
The technical issues of leakage, service life is short, and replacement cost is high, influences reaction efficiency, provide it is a kind of high pressure resistant, in a high voltage state
Sealing effect is good, is not easy to leak, and long service life, replacement cost is low, improves the reaction kettle sealing device of reaction efficiency.
For this purpose, the technical solution of the utility model is, a kind of reaction kettle sealing device, including reaction kettle barrel and stirring
Axis, reaction kettle barrel are equipped with sealing gland, and sealing gland is equipped with sealing axle sleeve, is located on agitating shaft on sealing axle sleeve, close
Sealed cover is equipped with axial seal grooves, and reaction kettle barrel is equipped with radial seal groove, and sealing gland is threadedly coupled with sealing axle sleeve,
It is equipped with primary seal pad between sealing axle sleeve upper surface and sealing gland, it is close that second level is equipped between sealing gland and reaction kettle barrel
Packing.
Preferably, sealing axle sleeve inner hole excessively cooperates with agitating shaft outer circle, and sealing axle sleeve upper end screws flat in parallel equipped with two
Face, sealing axle sleeve material are red copper.
Preferably, sealing gland is bolted with reaction kettle barrel, and clamp screw is equipped between sealing gland and sealing axle sleeve
Nail, holding screw are with brill.
The utility model beneficial effect is that, due to being equipped with reaction kettle barrel and agitating shaft, reaction kettle barrel is equipped with sealing
Gland, sealing gland are equipped with sealing axle sleeve, are located on agitating shaft on sealing axle sleeve, and sealing gland is equipped with axial seal grooves,
Reaction kettle barrel is equipped with radial seal groove, and sealing gland is threadedly coupled with sealing axle sleeve, and sealing axle sleeve upper surface and sealing are pressed
Between lid be equipped with primary seal pad, between sealing gland and reaction kettle barrel be equipped with secondary seal pad, when in reaction kettle medium into
When row reaction, pressure becomes larger in kettle, generates very high pressure to sealing axle sleeve, due to depositing for axial seal grooves and radial seal groove
, and sealing axle sleeve material is red copper, causes sealing axle sleeve to generate deformation along the direction of seal groove, and closer with agitating shaft
Cooperation, play the role of sealing, improve sealing effect, be not easy to leak, extend service life, reduce and be replaced with
This, improves reaction efficiency.

Specific embodiment
The utility model is described further below with reference to embodiment.
A kind of reaction kettle sealing device, including reaction kettle barrel 1 and agitating shaft 4, reaction kettle barrel 1 are equipped with sealing pressure
Lid 2, sealing gland 2 are equipped with sealing axle sleeve 3, are located on agitating shaft 4 on sealing axle sleeve 3, and sealing gland 2 is equipped with axial seal
Slot 9, reaction kettle barrel 1 are equipped with radial seal groove 8, and sealing gland 2 is threadedly coupled with sealing axle sleeve 3,3 upper surface of sealing axle sleeve
It is equipped with primary seal pad 10 between sealing gland 2, secondary seal pad 7 is equipped between sealing gland 2 and reaction kettle barrel 1, it is close
Envelope 3 inner hole of axle sleeve excessively cooperates with 4 outer circle of agitating shaft, is easily installed, and 3 upper end of sealing axle sleeve is equipped with two and screws plane 301 in parallel,
3 material of sealing axle sleeve is red copper, and sealing gland 2 is connect with reaction kettle barrel 1 using bolt 6, sealing gland 2 and sealing axle sleeve 3
Between be equipped with holding screw 5, holding screw 5 be with brill.
When medium is reacted in reaction kettle, as pressure becomes larger in kettle, higher and higher pressure is generated to sealing axle sleeve 3
Power, due to the presence of axial seal grooves 9 and radial seal groove 8, and 3 material of sealing axle sleeve is red copper, cause sealing axle sleeve 3 along
The direction generation deformation of seal groove, expansion makes it full of seal groove outward, and inwardly extruding and the closer cooperation of agitating shaft 4, rise
The effect for having arrived sealing, improves sealing effect, is not easy to leak, extends service life, reduce replacement cost, improves anti-
Answer efficiency.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the utility model patent protection scope,
It should still belong to the scope that the utility model claims book is covered.
