Summary of the invention
In view of the situation of above-mentioned technology, the utility model provides a kind of improved self-adjustable sintering machine head end tail sealing device, and it has dodges and reset function flexibly the purpose that reaches sealing and prolong seal life automatically.
For achieving the above object, the utility model provides a kind of self-adjustable sintering machine head end tail sealing device, comprises movable table top, is connected on the shell bottom plate by pull bar that is provided with and the spring that is installed on it, and wherein said pull bar and movable table top are for being hinged; Be provided with the arc-shaped guide plate of preventing jam with the abutting end of movable table top and shell; On described movable table top inner face, be evenly equipped with the big rectangle cooling water pipe of contact area.Thereby when big foreign matter (as pallet grate bar) appears in arbitrary position between sealing device upper table surface and the chassis lower frame, when this activity table top can be dodged automatically, can realize contacting preferably sealing with chassis again, and by hinge point reset flexibly and by good fit arc-shaped guide plate, promptly play sealing function, eliminated the problem of jam again; In addition, improved rectangle cooling water pipe because of having increased film-cooled heat, has improved the service life of sealing device.
In this is novel,, on the pull bar between described movable table top and the housing base plate, spring, the dustproof metal bellows is set according to the requirement of site of deployment.Its effect is to avoid the dust of working site to enter, and reduces the course of work of cleaning dust.
In this was novel, the abutting end between described movable table top and shell was provided with the ripple compensation plate.In order to prevent that dust from entering arc-shaped guide plate and playing sealing function.
The good effect of the self-adjustable sintering machine head end tail sealing device that this is novel is: the pull bar of installing on movable table top is for being hinged, so when the front end of big foreign matter (pallet grate bar) crush seal device, chassis gravity reaches hinged place and spring by foreign matter, movable table top, spring compression and movable table top compression zone position are descended simultaneously, and the position of lifting of this activity table top contacts sealing with chassis; Simultaneously,, adopted the arc-shaped guide plate cooperation, promptly realized sealing, can prevent the jam phenomenon again for realizing dodging function preferably, and the film-cooled heat by increase activity table top, reduced the camber of spring inefficacy, improved the service life of sealing device.
Description of drawings
Fig. 1 is this novel topology view.
The specific embodiment
Beneficial effect below in conjunction with accompanying drawing embodiment describes the utility model in detail and has is intended to help the reader to understand essence of the present utility model better, but can not constitutes any qualification to enforcement of the present utility model and protection domain.
By shown in Figure 1, this self-adjustable sintering machine head end tail sealing device comprises a movable table top 5, and its inner face is hinged by articulated manner and the pull bar 1 that is installed on the housing base plate 9; Pull bar 1 between this activity table top 5 and the housing base plate 9 and hinge point are installed metal bellows 6, avoid entering of dust and influence the stroke of spring with this.Consider that simultaneously movable table top 5 can automatically reset after being subjected to as pallet grate bar extruding decline, and the abutting end between movable table top 5 and housing 7 is provided with arc-shaped guide plate 2 under the effect of spring 8.When so no matter movable arbitrary position pressurized of table top 5 tilt, can not produce and interfere the jam phenomenon, realize dodging automatically the better sealing effectiveness of maintenance that resets.In actual applications, for reducing the heating temperature of movable table top 5, and on the inner face of movable table top 5, be evenly equipped with rectangle cooling water pipe 4, utilize the contact area of rectangle cooling water pipe 4 to increase cooling effect, the table top that takes in sail 5 reaches because of heating temperature is too high to spring 8 and produces the possibility of spring failure, and influences sealing effectiveness.Movable table top 5 in above-mentioned is choristas with housing 7, has the slit between its two body, easily enters dust, for this reason, can play a dustproof and sealing function preferably by a ripple compensation plate 3 is installed between its two body.
Dodging automatically of this self-adjustable sintering machine head end tail sealing device: when big foreign matter (pallet grate bar) squeezes arbitrary end at movable table top 5, because of the gravity of chassis is to reach pull bar 1, hinged place and compression spring 8 by foreign matter, movable table top 5, movable table top 5 pressurized positions are descended.Because of slotted hole (not marking among the figure) is arranged on the hinged place, so pull bar 1 does not have interference with movable table top 5 liftings; If when foreign matter was displaced downwardly to the middle part in the drive of chassis (being to mark among the figure), the spring 8 at each position all was compressed, movable table top 5 vertical lifts remain contact condition.
The utility model can be according to the present situation of this operation, when burn-off phenomenon occurring as the chassis bottom girder, cause the chassis bottom girder to cross easily and crumple, promptly become the chassis bottom girder of a downward convex surface, for the movable table top of parallel end faces, can't guarantee and its sealing in this case.But the cost of chassis is very high, can not change chassis.For addressing this problem, the chassis that its bottom girder is out of shape can continue to use, and reduces production costs.At this moment, the movable table top 5 in the sealing device of said structure can be made specially the identical concave curved surface of bottom girder curve of convex surface under an energy and the chassis, the concave and convex surface of such two bodies matches, and has realized sealing.
