Abstract
The utility model overcomes it is not enough that prior art exists, provides a bell -type furnace sand seal structure that is used for continuous high temperature annealing of tunnel type orientation silicon steel, atmosphere gas is hard to to seal up when having solved continuous annealing problem, in order to solve the technical problem, the utility model discloses a technical scheme do: a bell -type furnace sand seal structure that is used for continuous high temperature annealing of tunnel type orientation silicon steel, includes platform truck, inner cover and quartz sand, the inner cover sets up the upper end at the platform truck, the up end of platform truck is provided with an annular recess, the quartz sand is filled in the recess, the inner cover corresponds to be detained in the recess, inner cover, quartz sand and recess cooperation form the hermetic cavity body, the utility model discloses but wide application in oriented silicon steel continuous annealing furnace field.
Description
Technical field
A kind of bell furnace sand seal structure for the annealing of tunnel type orientation silicon steel continuous high temperature of this utility model, belongs to orientation
Silicon steel continuous annealing furnace technical field.
Background technology
It is more difficult that the closed chamber that existing annealing furnace inner cover and chassis are formed seals, and it is more complicated to make sealing, is adding simultaneously
During heat, expanded by heating also can cause the problems such as seal wear.
Utility model content
This utility model overcomes the deficiency that prior art exists, it is provided that a kind of the highest for tunnel type orientation silicon steel
The bell furnace sand seal structure of temperature annealing, the problem that when solving continuous annealing, atmosphere gas is difficult to seal.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of for tunnel type oriented silicon
The bell furnace sand seal structure of steel continuous high temperature annealing, including chassis, inner cover and quartz sand, described inner cover is arranged on the upper of chassis
End, the upper surface of described chassis is provided with an annular groove, and described quartz sand is filled in groove, described inner cover correspondence button
In groove, described inner cover, quartz sand and groove fit form the cavity sealed.
Preferably, the bottom of described groove is provided with the projection of annular straight up, and the bottom outside of described inner cover is arranged
Having the annular U-type groove that Open Side Down, described U-type groove is buckled in projection, forms sand seal structure with male cooperation.
This utility model compared with prior art has the beneficial effect that this utility model fills at filling place at chassis
After material, directly inner cover is placed on sand launder, in utilizing deadweight press-in sand launder, then continues to add quartz sand on top, completely by sand
Sealing groove fills up, and utilizes quartz sand to have mobility in sand sealing groove, though dolly expanded by heating or by cold events, all without shape
Becoming crackle, sand can be always maintained at the rustless steel sand launder with stove car and inner cover contacts, and remains the state of sealing, it is ensured that continuously
The sealing property of atmosphere gas during annealing.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of a-quadrant in Fig. 1.
Fig. 3 is axonometric chart of the present utility model.
In figure: 1 be chassis, 2 be inner cover, 3 be quartz sand, 4 be groove, 5 for protruding, 6 be U-type groove.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of bell-type for the annealing of tunnel type orientation silicon steel continuous high temperature of this utility model
Stove sand seal structure, including chassis 1, inner cover 2 and quartz sand 3, described inner cover 2 is arranged on the upper end of chassis 1, described chassis 1 upper
End face is provided with an annular groove 4, and described quartz sand 3 is filled in groove 4, and described inner cover 2 correspondence is buckled in groove 4,
Described inner cover 2, quartz sand 3 and groove 4 cooperatively form the cavity of sealing.
The bottom of described groove 4 is provided with the projection 5 of annular straight up, and the bottom outside of described inner cover 2 is provided with out
The annular U-type groove 6 that mouth is downward, described U-type groove 6 is buckled on protruding 5, cooperatively forms sand seal structure with protruding 5.
Operation principle of the present utility model: utilize quartz sand to have mobility in sand sealing groove, no matter dolly expanded by heating
Or by cold events, all without forming crackle, sand can be always maintained at the rustless steel sand launder with stove car and inner cover contacts, and protects all the time
Hold the state of sealing.
Work process of the present utility model: inner cover, after filling place feeds, is directly placed on sand launder by chassis, utilizes
In deadweight press-in sand launder, then continue to add quartz sand on top, completely sand sealing groove is filled up.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but on this utility model is not limited to
State embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible to without departing from this utility model objective
On the premise of various changes can be made.
