Abstract
The utility model patent proposes a kind of mechanical sealing device, it mainly by：Sealed rubber (1) 1, metal sealing block (2) 1, sealed rubber (3) 2, mechanical seal shell (4), sealed rubber (6) 3, metal sealing block (7) 2, sealed rubber (8) 4, India rubber set (9), spring (10), screw (11), " O " type elastic tape (12) etc. form.Two pairs of metal sealing blocks (2) 1 and metal sealing block (7) 2, sealed rubber (1) 1, sealed rubber (3) 2, sealed rubber (6) 3, sealed rubber (8) 4 are respectively provided with its outer surface.The India rubber set (9) that an outside is cased with a spring (10) is assembled between, one mechanical seal shell (4) is fixed to be used, and has 8 screw holes and the groove of assembling " O " type elastic tape (12) on its base.This patent beneficial effect is compact-sized, easy for installation, good sealing effect.
Description
Technical field
The utility model patent is related to a kind of mechanical sealing device, and it is to be directly installed on outside reactor to turn
On axle, to playing buffer action inside and outside reactor, no matter it is vacuum state in reactor or has pressure state to use, it
Feature is to use two mechanical seals, it is ensured that the not outside spill and leakage of container inner medium, ensures qualified product.
Background technology
Reactor is commonly used in chemical industry production, and several media can be heated and be stirred simultaneously by it, be heated
It is stirred process and usually has gas generation, in order to not allow caused toxic and harmful gas outwards to overflow, pollutes environment and wound
Evil body, so General reactions kettle is equipped with mechanically-sealing apparatus in rotating shaft.Currently used mechanical seal is main in structure
The bounce of spring is relied on to allow two pieces of metal bumps face contact seals together, when pressure medium is more than bullet in reactor
During the elastic force of spring, mechanical seal is just opened by top, and sealing just fails.
The content of the invention
This patent proposes a kind of mechanical sealing device, it mainly by：Sealed rubber (1) 1, metal sealing block (2) 1,
Sealed rubber (3) 2, mechanical seal shell (4), sealed rubber (6) 3, metal sealing block (7) 2, sealed rubber (8) 4, elastic rubber
Leather sheath (9), spring (10), screw (11), " O " type elastic tape (12) etc. form.Two pairs of metal sealing blocks (2) 1 and metal sealing
Block (7) 2, sealed rubber (1) 1, sealed rubber (3) 2, sealed rubber (6) 3, sealed rubber (8) are respectively provided with its outer surface
4.The India rubber set (9) that an outside is cased with a spring (10), a machinery are assembled between this two pairs of metal sealing blocks
Sealing shell (4) is used to fix whole mechanically-sealing apparatus, there is 8 screw holes and assembling " O " type rubber on its base
Enclose the groove of (12).
The method of assembling：First by outside (2) 1 sets of a pair of metal sealing blocks with rubber (1) 1, sealed rubber (3) 2
In the rotating shaft (5) of reactor, be loaded on the India rubber set (9) that outside is cased with a spring (10), then it top it is same
Sample is loaded onto outside another pair with sealed rubber (6) 3, the metal sealing block (2) 1 of sealed rubber (8) 4, is finally loaded on machinery
Sealing shell (4), built-in " O " type elastic tape 12 of groove by its base screw hole, is fixed on instead with 8 screws (10)
Answer on kettle body.
Mainly by that root spring (10) of centre, being compacted the bounce of rear spring makes two pairs of collisions exist for whole mechanical seal
Metal sealing block face together contacts to seal.When reacting kettle inner pressure exceeds the thrust of spring, just start first
Mechanical seal is failed, and the gas of overflow is entered in shell (4), and second mechanical seal is back pressure type, more, the effect of leakage
It is also bigger in the thrust on metallic sealing section, so second mechanical seal can effectively prevent to react leaking for gas reactor.
This patent beneficial effect is compact-sized, easy for installation, good sealing effect.
Brief description of the drawings
This patent is described further with reference to the accompanying drawings and examples.
Fig. 1 is a kind of mechanical sealing device mounting structure schematic diagram.
(1), sealed rubber 1 in figure, (2), metal sealing block 1, (3), sealed rubber 2, (4), mechanical seal shell,
(5), rotating shaft, (6), sealed rubber 3, (7), metal sealing block 2, (8), sealed rubber 4, (9), India rubber set, (10), bullet
Spring, (11), screw, (12), rubber "O"-ring.
Embodiment
The utility model patent proposes a kind of mechanical sealing device, it mainly by：Sealed rubber (1) 1, metal sealing
Block (2) 1, sealed rubber (3) 2, mechanical seal shell (4), sealed rubber (6) 3, metal sealing block (7) 2, sealed rubber (8) 4,
India rubber set (9), spring (10), screw (11), " O " type elastic tape (12) etc. form.Two pairs of metal sealing blocks (2) 1 and gold
Belong to sealing block (7) 2, sealed rubber (1) 1, sealed rubber (3) 2, sealed rubber (6) 3, sealing are respectively provided with its outer surface
Rubber (8) 4.An outside is assembled between this two pairs of metal sealing blocks and is cased with the India rubber set (9) of a spring (10), one
Mechanical seal shell (4) is to fix whole mechanically-sealing apparatus when being assembled in reactor rotating shaft (5) to use, on its base
There are 8 screw holes and the groove of assembling " O " type elastic tape (12).
The method of make-up machinery sealing device：First by outside a pair of metals with rubber (1) 1, sealed rubber (3) 2
Sealing block (2) 1 is enclosed in the rotating shaft (5) of reactor, is loaded on the India rubber set (9) that outside is cased with a spring (10), then
Equally loaded onto in its top and sealed rubber (6) 3, the metal sealing block (2) 1 of sealed rubber (8) 4 are carried outside another pair, most
After be loaded on mechanical seal shell (4), built-in " O " type elastic tape (12) of groove by its base screw hole, with 8 spiral shells
Silk (10) is fixed on reactor body.
