Foot is that sealing performance is slightly worse, and axis is not allow for biggish circular runout, and power consumption is big, wears axis, and service life is short.
Mechanical seal refer to by least a pair of end face perpendicular to rotation axis Fluid pressure and compensation mechanism elastic force (or
Magnetic force) under the action of and the cooperation of auxiliary seal under keep be bonded and constituted with respect to sliding prevent fluid leak dress
It sets, is a kind of gland seal device of rotating machinery, its advantage is that good airproof performance, performance is stablized, and leakage rate is few, and friction power loss is low, makes
It is long with the period, very little is worn to axis, is able to satisfy various working requirement.Its deficiency be mechanism is complicated, the accuracy of manufacture is high, price compared with
Expensive, maintenance inconvenience.
Utility model content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, propose a kind of sealing dress of reaction kettle rabbling mechanism
It sets, solves in the prior art that there are leakproofness is insufficient, the service life is short using packing seal merely, and use mechanical seal cost merely
The technical issues of height, inconvenient maintenance.
To reach above-mentioned technical purpose, the technical solution of the utility model provides a kind of sealing of reaction kettle rabbling mechanism
Device, comprising:
Collet is abutted with reaction kettle；
Packing seal component, is sheathed on agitating shaft, and is set on the reaction kettle end face abutted with the collet；
And
Mechanical sealing assembly is sheathed on agitating shaft, and is disposed far from the collet end face of the reaction kettle.
Compared with prior art, the beneficial effects of the utility model include: to combine packing seal and mechanical seal, both
It is easy to replace the part of abrasion, and has good sealing effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of packing seal assembly embodiment 1；
Fig. 3 is the structural schematic diagram of packing seal assembly embodiment 2.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model provides a kind of shaft sealer of reaction kettle rabbling mechanism, as shown in Figure 1, comprising: collet 1,
Packing seal component 2 and mechanical sealing assembly 3.
Collet 1 is abutted with reaction kettle 4.
Packing seal component 2 is sheathed on agitating shaft 41, and is set to 4 end face of the reaction kettle abutted with the collet 1
On.
Mechanical sealing assembly 3 is sheathed on agitating shaft 41, and is disposed far from 1 end face of the collet of the reaction kettle 4.
When work, packing seal component 2 prevents seam of the reactant between reaction kettle 1 and agitating shaft 41 in reaction kettle 1
It escapes in gap, realizes first order sealing.If a small number of reactants occur successfully to escape, the reactant escaped can only fall into collet 1
In, and prevented in collet 1 by the more powerful mechanical sealing assembly 3 of leakproofness, i.e., mechanical sealing assembly 3 realizes that the second level is close
Envelope.The above two-stage sealing perfection avoids the escape of reactant in reaction kettle 4, and wherein packing seal undertakes main sealing duty
Appoint, structure is simple, replacement is convenient, low-cost characteristic keeps entire shaft sealer use cost low.
Preferably, as shown in Figures 2 and 3, the packing seal component 2 includes seal receptacle 21, sealing cover 22, adjusts
Tongue 23 and elastic filler 24, the seal receptacle 21 have packing cavity open at one end, and the elastic filler 24 is placed in the packing cavity
Interior, the adjusting tongue 23 protrudes into packing cavity by the opening of the packing cavity and abuts the elastic filler 24, the sealing cover 22
It abuts the adjusting tongue 23 and is connect by adjusting bolt 25 with the seal receptacle 21.Using the knot of aforementioned filler seal assembly 2
Structure, it can be achieved that leakproofness it is adjustable.Specifically, being adjusted according to required seal request by screwing or unscrewing adjusting bolt 25
Sealing cover 22 is saved at a distance from seal receptacle 21, to control to adjust the axial direction with agitating shaft 41 that tongue 23 applies elastic filler 24
Parallel extruding force, and then elastic filler 24 therefore extruding force and the deformation radial parallel with agitating shaft 41 that occurs are adjusted, from
And the leakproofness needed for adjusting.
Preferably, the elastic filler 24 includes that tile shape sealing ring 24a and Packing seat 24b, the tile shape are close
The section of seal 24a is tile shape, and inner ring surface abuts agitating shaft 41, and outer ring surface abuts the packing cavity chamber of the seal receptacle 21
Wall；The Packing seat 24b at least there are two, be located at the both ends of the tile shape sealing ring 24a.The sealing ring of tile shape can
Meet by deformation needed for being generated when adjusting the extruding of tongue 23, and restorable self- recoverage energy can be generated when extruding force reduces
Power is very suitable to the demand of this programme.
Preferably, as shown in Fig. 2, the tile shape sealing ring 24a has multiple, adjacent two tiles shape sealing ring 24a
It is oppositely arranged.Oppositely arranged advantage is sensitive to extruding force, and required deformation can occur without too high extruding force, seals
Property adjust it is more labor-saving.
Preferably, as shown in figure 3, the tile shape sealing ring 24a has multiple, adjacent two tiles shape sealing ring 24a
Setting in the same direction.It has the advantage that in the same direction, under the premise of installation space is certain, mountable more sealing rings, leakproofness
It can be improved, meanwhile, the deformation needed for needing bigger extruding force to realize, leakproofness adjusts relatively laborious.
Preferably, the collet 1 includes collet ontology 11 and nozzle 12, the collet ontology 11 is hollow structure,
The nozzle 12 is connect with the collet ontology 11, for the inner cavity of the collet ontology 11 to be in communication with the outside.When filler is close
When the reactant escaped at envelope can be ignored, the nozzle 12 can be used for connecting the cooling devices such as blower, be that this axis is close
Seal apparatus cooling, guarantees its optimum Working；It, can when the reactant escaped at packing seal is more or has accumulated more
To export reactant by the nozzle 12, guarantee the normal operating conditions of this shaft sealer.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model.
Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical
In novel scope of protection of the claims.
