Description
Technical field
The present invention relates to mixing plant technical field, more particularly to a kind of gland seal device of Horizontal stirring equipment.
Background technology
Horizontal stirring equipment is generally used for mixing the materials such as high viscosity, high solids content, slurry, dough, wet-milling, and had sets
Standby interior medium is poisonous, inflammable and explosive, contains solid particle, and some process conditions have high temperature, high pressure, high-viscosity feature.Sleeping
Formula mixing plant typically by cylinder, 07 plate of end cap of cylinder both sides, through 07 plate of whole cylinder and both sides end cap shaft,
Gland seal device on 07 plate of end cap, the agitator on shaft, motor, gear-box and other adnexaes composition.
As large-scale Horizontal stirring equipment is general all long, cylinder is divided into multistage, after processing and alignment error accumulation, positioned at cylinder
The often decentraction and two sealing surfaces are not parallel of the position of gland seal device installed by 07 plate of end cap of both sides, and shaft is due to itself
The reason for weight, exacerbate the eccentric degree of shaft and gland seal device.
The gland seal device of Horizontal stirring device configuration is generally conventional packing seal or mechanical seal on the market.Refer to
Fig. 1 and Fig. 2, Fig. 1 are a kind of conventional packing seal structure schematic diagram in prior art；Fig. 2 is a kind of band ripple in prior art
The packing seal structure schematic diagram of stricture of vagina tubular type.And traditional gland seal device either packing seal or mechanical seal to install
Precision has a high requirement of comparison, the effect and life-span of the bias of cylinder two ends sealing surface and the sealing of out of plumb degree direct influence,
It is easily caused and is sealed in short period internal leakage and damage, not only has a strong impact on product quality, and pollute environment, infringement operation
Personnel's is healthy；Also, all it is conventional production, common packing seal or mechanical seal mostly, it is impossible to meet complicated work
The demand of the large-size horizontal equipment under condition, as conventional packing seal or mechanical seal can not meet some of complex operating mode
Under large-size horizontal equipment occasion application, limit its range of application.
Conventional packing seal structure handling ease, cheap, simple to operate.But the bias due to shaft, filler
Circumferential weld between case 01 and axle is uneven, and filler 04 just uniformly cannot be compressed, and leaves seam between the filler 04 and axle sleeve 06 of side
Gap, medium bring hidden trouble easily by this slot leakage to production safety.Specifically, whole packing seal is to rely on
The seam of 01 bottom of stuffing box is engaged to position with the seam on horizontal equipment end cap 07.Base ring 00, oil ring 02 and gland 05
Due to being metal material, in order to not collide with the axle sleeve 06 of rotation, the monolateral gap of 06 external diameter of span axle sleeve in which is typically designed
For 1～2mm, if the seam concentricity on horizontal equipment two ends end cap 07 is as processing and alignment error cumulative departure are more than 1
～2mm, base ring 00, oil ring 02 and gland 05 directly can be collided with axle sleeve 06, cause shaft rotate.If horizontal equipment
When seam Concentricity tolerance on two ends end cap 07 is not less than 1～2mm, only a small amount of bias, although filler 04 has floating elastic,
But the bias due to shaft, the circumferential weld between stuffing box 01 and axle are uneven, filler 04 just uniformly cannot be compressed, and side is filled out
Leave gap between material 04 and axle sleeve 06, medium easily by this slot leakage, filler 04 and axle sleeve 06 this between friction pair
Gap be produce leakage main path.The common erection sequence of horizontal equipment is that shaft passes through the axle on two ends end cap 07
Hold to position, the position finally according to axle is installing packing seal.If two end cap 07 is led due to processing and alignment error accumulation
Two end cap 07 and axial line out of plumb is caused, it is to incline that can cause whole axle, and packing seal is pacified according to the position of axle
Dress, erecting bed often occurs the feelings that the seam of stuffing box 01 can not coordinate and can not install Shang Qu with the seam of end cap 07
Condition.In order to avoid dry friction, extend gland sealed working life, the built-in oil ring 02 of conventional packing seal, by oils and fatss
Entrance 03 is toward injection oils and fatss or lubricating fluid in oil ring 02, it is ensured that filler 04 has enough lubrications with 06 surface of axle sleeve.This structure
The working condition of filler 04 is simply improved, when the situation of pressure is had in kettle, can only be by constantly tightening filler pressure
Bolt on lid 05 reaches the purpose of sealing to compress filler 04.But filler 04 is tighter, seal pressure is bigger, filler 04 can be made fast
Speed abrasion even can also produce the phenomenon for seizing excessively heated axle, so as to cause production accident.When the situation for occurring high temperature in kettle, temperature
Filler 04 can be passed to by axle, accelerate the aging of filler 04 and failure.Conventional packing seal does not compensate radial compaction automatically
Filler device, needs often to be adjusted the compression degree of filler 04, makes the lubricant in filler 04 in operation a period of time
After loss, then some lubricants are extruded, while the thrust that compensation filler 04 is caused because of change in volume relaxes.So operate not
Only bother, the size of most importantly uncontrollable thrust, press get Tai Song not have the effect of sealing, press too tight, can make
Interrupt into filler oil film and accelerate a series of consequences such as filler, the abrasion of axle sleeve 06.
Common single mechanical end face seal stationary ring is fixed on 07 plate of end cap of equipment, and rotating ring is fixed on axle, due to dynamic
The bias of 0.5mm is typically allowed between stationary ring, so countershaft bias has certain compensation dosage, but due to medium in equipment
Contain solid, or high viscous material, easily solidify after cooling or precipitation, the rubbing surface between dynamic and static ring in the presence of solid particle at once
Failure.Further, since material and the spring location contacts in stationary ring, seal after solidification and lose because losing the compensation ability of spring
Effect.Common double-face mechanical sealing structure principle does not have the difference of essence with single mechanical end face seal, can not be in this occasion
Lower use.
Traditional packing seal is improved, traditional being rigidly connected is changed to corrugated tube 08 and is connected, corrugated tube 08
It is installed on filler seat 09.The no matter axial direction or radial direction has certain compensation dosage of corrugated tube 08, not only can make up sleeping
Decentraction or off plumb defect at the sealing that formula equipment is caused due to processing and alignment error accumulation, it is also possible to resist horizontal
Agitator is in whipping process due to shaft run-out that agitator self gravitation and material cause to the impact of agitator.
But the drawbacks of this structure also has certain, a kind of situation for occurring often is：The weld of corrugated tube 08 is often torn.
This be due to frequently stretching, bending can cause the fatigue stress of corrugated tube 08, and most weak where the portion namely welded
Position is often destroyed at first.Also a kind of situation can also run into：Height in horizontal equipment glues the inner side that material enters corrugated tube 08,
It is set in after cooling or precipitation in corrugated tube 08, causes corrugated tube 08 to fail.
In sum, how the requirement for having comparison high to installation accuracy, the bias of cylinder two ends sealing surface are efficiently solved
The problems such as effect sealed with out of plumb degree direct influence and life-span, be that current those skilled in the art are badly in need of asking for solution
Topic.
