Description
Technical field
The present invention relates to a kind of wheeled flexible seal device, be arranged on the two ends of the first tail of sintering machine one, belong to metallurgy sintered apparatus field.
Background technology
The seal device of sintering machine of prior art, is arranged on the two ends of the first tail of sintering machine one, and head installs one group, and afterbody installs one group or two groups,
Each group of rigid seal buttress divides 3～5 pieces according to chassis width.Its Main Function has 2 points, and one is to seal with the pallet in movement, and two is with quiet
The most motionless bellows seal, and are all movable sealing at two.Their working condition very severe, high temperature, negative pressure, many dirt, chassis sideslip, chassis are combed
Material leakage between son, chassis collapse waist (referring to that chassis sealing surface is heated the most convex deformation, is become arcwall face from plane) etc..Sealing device kind is more substantially
Dividing three major types, a class is spring seal unit；Two classes are connecting rod weight sealing devices；Three classes are other, such as magnetic sealing device etc..
Spring seal unit: mainly use spiral compression spring, vertically arranged spiral compression spring is in 90 ° with chassis traffic direction, works as chassis
When operation contacts with sealing device, produce radial thrust to spring, chassis collapses that waist, sideslip produce in addition radial thrust deviation longitudinal center,
Spring cisco unity malfunction, the gap that the sealing plate of point polylith is reserved, extruding is dead each other.Also have due to high temperature, negative pressure, material leakage etc., make spring
Lost efficacy.The most old-fashioned body structure spring sealed, casing is fixed with bellows, sealing plate under the action of the spring, while sealing with chassis with
Box sealing, the wretched insufficiency that it exists is, spiral compression spring lost efficacy, and seal clearance is very big, leaks out very serious, and is easy to by dust stratification
Blocking is dead, is the most substantially eliminated.
Connecting rod Weight type sealing device: for overcoming the scarce filling of spring seal unit, uses connecting rod Weight type, can indulge along sintering machine under the effect of weight
To movement, overcome the radial thrust to sealing device, make sealing plate up and down to realize in moving simultaneously and chassis seals, at present by most of factory of China
Family uses.
More typically, the four link type of Introduced from Japan technology adds metallic flex asbestos board weight sealing device to First Phase of Baosteel Project ratio, seals with chassis and bellows
The technology of synchronous sealed at two.Quadric chain, under the effect of weight, makes sealing plate seal with chassis.Sealing plate one install metallic flex stone
Cotton plate is also connected with bellows, and the mountain flesh plate action the most therewith when sealing plate action relies on flexible deformation and realizes the synchronous sealed with bellows.But by
In chassis material leakage produce grit, high temperature, negative pressure effect under, grit, to fierce the washing away of metallic flex asbestos board, makes mountain flesh plate electrode easy
Breakage, short-lived, cause serious leaking out.
In order to solve this problem, Baosteel two, three phase Introduced from Japan technology, cancel mountain flesh plate, the double lever type weight using synchronous sealed is close
Seal apparatus, is characterized in: double lever operation principle is identical with double leval jib, except for the difference that utilizes lever activity to hand over fulcrum to make movable support plate of handing over, movable
Handing over support plate is the friendship fulcrum of lever action, is again to be connected the sealing plate of yarn with bellows, and under the effect of weight, double lever achieves in movement up and down
Lifting, can remain and seal with chassis, also achieve synchronous sealed at chassis and bellows two simultaneously.
The Japanese double leval jib of above-mentioned introduction, double lever Weight type Sealing Technology, typically divide 3～5 pieces to be one group according to chassis width sealing plate, block and block
The free gap stayed, total backlash amount is big, and piecemeal is many, and the linkage friendship of setting is the most, and mechanism is complicated, and poor rigidity, intensity is low.Typically in peace
Dress starting stage, be active in one's movements relatively good use, but use less than 1 year linkage and just do not move, and loses the effect of sealing, this be due to
The being stained with property grit that technique produces, under the effect of negative pressure, by the friendship support plate blocking handing over fulcrum, double lever of double leval jib, particularly hands over support plate contact surface
Big reason is easier to block, and also has due to the impact of the factors such as chassis manufacture deviation, sintering machine alignment error, and chassis self is by cold and hot in addition
Alternation affects generation and collapses waist, causes chassis deviation longitudinal center more or less to run, and the deviation longitudinal center thrust of generation acts on sealing plate,
This thrust or left or right, cause polylith sealing plate to be mutually squeezed, and connecting rod is handed over to prop up and deformed by torsion, and particularly the friendship support plate of double lever is by torsion more
Greatly, the passage asked at any time, gradually blocking increases the weight of, deforms and increase the weight of, and loses the effect of sealing completely.
The deficiency existed for connecting rod Weight type sealing device, at present, the spring sealed mode of relogging, also has a variety of mode again.As: wherein
A kind of modified model spring seal unit is to the effect that: using spiral compression spring to add temperature resistant rubber hose, one is that spring is arranged vertically, and spring is vertical
Compression and extension make sealing plate seal with chassis.Two is that temperature resistant rubber hose is arranged between sealing plate and bellows, when spring-compressed and extension band movable sealing
When plate is upper and lower, temperature resistant rubber hose is also simultaneously by compression and extension, it is achieved that and the sealing between bellows.Its advantage is, does not has old-fashioned casing to tie
Structure, spring is not easy to be blocked by grit.Chassis and bellows synchronous sealed, the temperature resistant rubber hose simple in construction of employing.But can not avoid above-mentioned,
In bad working environments condition, the vertical spiral compression spring thrust that produces deviation longitudinal center in 90 ° with chassis traffic direction, make spring by torsion very
Greatly, the sealing plate extrusion of piecemeal, sealing effectiveness is undesirable.
