2. simple for structure, easy for operation, long service life;

3. make, maintenance cost is cheap, be convenient to promote the use of.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of an embodiment of the utility model;

Fig. 3 is the enlarged diagram of A portion structure among Fig. 1.

1 is rigid tray among the figure, 2 is flexible exotic material layer, 3 is rigidity four connecting rod expansion brackets, 4 is leading screw, and 5 is device of rotation driving, and 6 is kiln chassis or ground, 71 and 72 for being arranged on the nut member on the screw mandrel, 8 is the kiln side wall, and 9 is the sealing between kiln side wall and the packaged type kiln car, and 10 is the packaged type kiln car.

The specific embodiment

Among Fig. 1, the utility model constitutes movable sealing device by flexible exotic material layer 2, rigid tray 1 and at least one group of machinery four connecting rod elevating mechanisms, wherein, flexible exotic material layer 2 is arranged on the rigid tray 1, and mechanical four connecting rod elevating mechanisms are positioned between rigid tray and kiln chassis (or ground) 6.

Its described mechanical four connecting rod elevating mechanisms are made of one group of rigidity, four connecting rod expansion brackets 3 and a rhizoid thick stick 4, an end points 31 of rigidity four connecting rod expansion brackets connects with rigid tray, another end points 32 of its correspondence connects with kiln chassis (or ground), all the other two

end points

33 and 34 respectively be arranged on screw mandrel on

nut member

71 and 72 corresponding connections, an end of screw mandrel is provided with device of rotation driving 5.

Above-mentioned flexible exotic material layer and rigid tray and body of heater length are isometric, and the quantity of mechanical four connecting rod elevating mechanisms can be provided with one group or array as required.

Above-mentioned device of rotation driving generally can adopt handwheel or handle form, drives with manpower; If the client needs, also can adopt other forms of device of rotation driving (as motor etc.) to drive.

Above-mentioned rigidity four connecting rod expansion brackets and rigid tray, kiln chassis or ground and to be arranged on connecting between the nut member on the screw mandrel be that pivot pin connects.

In actual manufacture process, mechanical four connecting rod elevating mechanisms are processing and fabricating specially, also can adopt existing product with same structure or function (as automobile with the hand-rail type jack etc.) to substitute, to reduce the workload of cost of manufacture and member processing.

Among Fig. 2, side under the sealing 9 between kiln side wall 8 and the packaged type kiln car 10 is provided with by flexible exotic material layer 2, rigid tray 1 and at least one group of Liftable type movable sealing device that machinery four connecting rod elevating mechanisms constitute.

When the elevating mechanism rising puts in place, end in contact under the sealing between flexible exotic material layer and kiln side wall and the packaged type kiln car is carried out forced seal to it, prevents high-temperature gas in the kiln " following scurrying ", damage kiln car and ground-engaging element thereof, can reduce scattering and disappearing of the interior heat of kiln simultaneously.

When elevating mechanism decline puts in place, to hold under the sealing between flexible exotic material layer and kiln side wall and the packaged type kiln car to disengage, kiln car can move freely and walks.

Among Fig. 3, the rib-loop direction that screw mandrel 4 and two end points nut members 71 of rigidity four connecting rod expansion brackets and 72 connect parts is opposite, like this, when screw mandrel when a direction is rotated,

nut member

71 and 72 moves in opposite directions, causes rigid tray to rise; When screw mandrel when another direction is rotated,

nut member

71 and 72 oppositely moves, rigid tray then descends.

Because the utility model adopted Liftable type forced seal structure, good sealing effect can prevent effectively that high-temperature gas in the kiln from " scurrying down ", damages kiln car and ground-engaging element thereof, also can reduce scattering and disappearing of heat in the kiln simultaneously.

The utility model can be widely used in the kiln car field of sealing technology of various periodic kilns the kiln (as shuttle kiln or platform car kiln).
