Hot interlayer 4-2 is along the steel brush 4-1 that continuous zigzag alternately penetrates its two sides, first is that heat-resisting interlayer 4-2 and its can be improved
The tightness degree that two sides steel brush 4-1 is combined improves the integral strength of sealing element 4；It is more importantly to significantly increase heat-resisting folder
The contact area of layer 4-2 and hot wind, it is ensured that the good sealing performance of sealing element 4.
Embodiment 6
Dynamic sealing device on the inside of the cold bed pallet bottom of the present embodiment, structure is substantially the same manner as Example 5, further
: it is fixed with the inspection straight-bar 8 for extending downward into lower connecting plate upper surface on bolt 5, and examines straight-bar 8 perpendicular to stationary beam 1.
Rubber slab is generallyd use in the prior art as sealing device, but it there are problems that following being difficult to overcome, it may be assumed that rubber
Offset plate elasticity is poor, cannot bear biggish pre-pressing force during the installation process, and rubber slab holds under high temperature environment after use
Yi Yin carbonization hardens and fractures, and the inleakage between cold bed trolley and bottom stationary beam is caused to obviously increase.Meanwhile it is existing
When sealing device in technology is replaced and by experience or works as inleakage substantially using needing replacing after a certain period of time
Just discovery needs replacing when dramatically increasing, and leads to not replace sealing device in time or the replacement sealing device time is too early, cause
Inleakage obviously increases or the wasting of resources.And in the present embodiment, using the sealing element 4 of specific structure, not only increase move it is close
Effect is sealed, and can be realized the monitoring function of dynamic sealing in use process, it is ensured that cold bed pallet bottom and 1 moment of stationary beam protect
Excellent sealing state is held, concrete operations are as follows:
With reference to Fig. 2,3 and 7, the encapsulating method of dynamic sealing device on the inside of the cold bed pallet bottom of the present embodiment, including it is following
Step:
Step A, sealing element is installed: getting out dynamic sealing device on the inside of cold bed pallet bottom as claimed in claim 7, and will be close
The lower end of sealing 4 is held out against in the upper surface of lower connecting plate, so that the elastic shrinkage that the length of sealing element 4 occurs 5~10% is (specific
It is taken 5%) in the present embodiment；
Step B, sealing element: dynamic sealing device on the inside of regular visit cold bed pallet bottom is replaced, when discovery sealing element 4 and inspection
It tests the holding of straight-bar 8 and replaces sealing element 4 when being parallel to each other, and 4 lower end of sealing element after replacement is held out against to the upper table in lower connecting plate
Face, so that 5~10% elastic shrinkage (taking 5% in specific the present embodiment) occurs for the length of the sealing element 4 after replacement.
In step A, the lower end of sealing element 4 is held out against in the upper surface of lower connecting plate, and the length of sealing element 4 is occurred
5~10% elastic shrinkage, can be by the elastic deformation of sealing element 4, so that its lower end is closely after installing for sealing element 4
It is contacted with lower connecting plate upper surface and (certain pre-pressing amount is set between 4 lower end of sealing element and lower connecting plate upper surface),
Hot wind is avoided directly to leak between 4 lower end of sealing element and lower connecting plate upper surface.Meanwhile when sealing element 4 is using one section
Between after, continuous frictional of the lower end of sealing element 4 by lower connecting plate upper surface was inevitably worn, with the time
Passage, the abrasion loss of 4 lower end of sealing element is increasing, since the locational space that sealing element 4 is installed is smaller, it is difficult to by naked eyes
Intuitively observe 4 lower end of sealing element occur due to abrasion loss is larger with lower connecting plate upper surface gap so as to cause leak out it is existing
As.In order to evade the air leakage phenomena that is likely to occur due to long-time uses of sealing element 4, in the present embodiment, it is fixed on bolt 5
The inspection straight-bar 8 of lower connecting plate upper surface is extended downward into, and examines straight-bar 8 perpendicular to stationary beam 1, by examining straight-bar 8 to make
To judge scale that whether sealing element 4 needs replacing, caused by are there is gap in 4 lower end of sealing element and lower connecting plate upper surface
Air leakage phenomena visualization, significantly improves the reliability of dynamic sealing device on the inside of the cold bed pallet bottom of the present embodiment.Specific step
In rapid B, dynamic sealing device on the inside of regular visit cold bed pallet bottom, when discovery sealing element 4 is parallel to each other with the holding of straight-bar 8 is examined
When, illustrate that 4 lower end of sealing element has been worn down to the state that nature extends at this time, i.e., under the withstanding on of 4 lower end no pressure of sealing element
Connecting plate upper surface, is further continued for being easy to cause using sealing element 4 between 4 lower end of sealing element and lower connecting plate upper surface at this time and occurs
Gap and leak out, it is therefore desirable to replacement sealing element 4 at the first time and holds out against 4 lower end of sealing element after replacement in lower connecting plate
Upper surface, still make replacement after sealing element 4 length occur 5~10% elastic shrinkage, it is ensured that sealing element 4 is good
Dynamic sealing effect.
It should be noted that sealing element 4 is heat-resisting including accompanying between two layers steel brush 4-1, two layers of steel brush 4-1 in the present embodiment
Interlayer 4-2, intermediate heat-resisting interlayer 4-2 can play the role of good isolation air, and the setting of two layers of steel brush 4-1 is on the one hand
It can protect intermediate heat-resisting interlayer 4-2, isolation air, it can in time more when finding the steel brush 4-1 damage of any side
The leaking out in advance without sealing element 4 of sealing element 4 is changed, on the other hand two layers of steel brush 4-1 setting ensures that sealing element 4 has one
Fixed elasticity, to realize that the monitoring of 4 service life of sealing element provides basis.
Present embodiments provide dynamic sealing device on the inside of a kind of cold bed pallet bottom, the dynamic sealing device is using face and face
Contact sealing, preferably solves the problems, such as that the sealing effect between cold bed trolley and bottom stationary beam 1 is poor, in cold bed trolley
It is sealed between bottom and stationary beam 1 using sealing element 4, specially the sealing element 4 including steel brush 4-1 is mounted on upper connector 2
On inner sidewall, dynamic sealing is realized in the upper surface that the brush finish of the lower end steel brush 4-1 closely withstands on lower connector 3 as sliding sealing surface；
Wherein steel brush 4-1 elastic deformability is good, the relative altitude minor change between the adaptive upper connector 2 of energy and lower connector 3,
Air Leakage caused by the relative altitude minor change between upper connector 2 and lower connector 3 is avoided, makes air leak rate of air curtain from original
50% drops to 20% hereinafter, improving the hot blast temperature of waste heat boiler, and boiler generated energy improves 10% or so, returns the current period in half a year
Hereinafter, reducing the power consumption of air blower, reduce sintering machine operation and maintenance cost, has important work to iron and steel enterprise's energy-saving and emission-reduction
With；And steel brush 4-1 wear-resisting property is good, service life is longer, and structure is simple, and easy for installation and maintenance cost is low.
Dynamic sealing device on the inside of the cold bed pallet bottom of the present embodiment, is applicable not only to cold bed pallet bottom and stationary beam 1
Between dynamic sealing, apply also for the sealing cooperation between similar dynamic and static object.
