The utility model solves the sealing structure that revolving furnace fume hood is used for used by its technical problem, including columnar work
The underface of fixed petticoat pipe body, and activity is arranged in dynamic petticoat pipe body, columnar fixed petticoat pipe body, the movable gas hood body matching
Petticoat pipe body can move up and down, and further include columnar seal closure, and the seal closure is fabricated from a flexible material, the upper end of seal closure
Match with the lower end of fixed petticoat pipe body and connect, the lower end of seal closure matches with the upper end of movable gas hood body to be connect.
Further, the seal closure is made of high-temperature-resistant flexible material.
Further, the height of the seal closure is more than or equal to the stroke that movable gas hood body moves up and down.
Further, further including more clothes-hooks, clothes-hook, movable gas hood body are provided in the circumferential direction of fixed cigarette cover body lower end
Clothes-hook is provided in the circumferential direction of upper end, the top and bottom of seal closure are provided with multiple hanging holes, and a hanging hole matching hangs over one
On clothes-hook.
Further, further include columnar first reinforcing sealing ring, columnar second reinforcing sealing ring, described the
The outside of the upper end of seal closure is arranged in one reinforcing sealing ring matching, and described second, which reinforces sealing ring matching, is arranged in seal closure
Lower end outside.
The beneficial effects of the utility model are: by the way that seal closure is arranged between movable gas hood body, fixed petticoat pipe body, and should
The material of seal closure is fabricated from a flexible material, and seal closure prevents flue gas spilling and air to enter, and has good sealing effect,
When movable gas hood body moves up and down, seal closure has extensibility, will not pull movable gas hood body, fixed petticoat pipe body, make
It is long with the service life, it is easy to use, it is easy to maintain, it is conducive to promote.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Components, position and number in figure: movable gas hood body 1, fixed petticoat pipe body 2, seal closure 3, first reinforce sealing ring
4, second sealing ring 5, clothes-hook 6 are reinforced.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model is used for the sealing structure of revolving furnace fume hood, including columnar movable gas hood body 1, circle
The central axis of the fixation petticoat pipe body 2 of tubular, movable gas hood body 1 and fixed petticoat pipe body 2 is in same vertical straight line, the activity
Petticoat pipe body 1 matches the underface that fixed petticoat pipe body 2 is arranged in, and movable gas hood body 1 can be along wherein under the action of power mechanism
Mandrel line moves up and down, and further includes columnar seal closure 3, and the seal closure 3 is fabricated from a flexible material, and seal closure 3 is to fold
Type structure, the upper end of seal closure 3 matches with the lower end of fixed petticoat pipe body 2 to be connect, the lower end of seal closure 3 and movable gas hood body 1
Upper end match connection.Seal closure 3 prevents flue gas spilling and air to enter, and has good sealing effect, movable gas hood
When body 1 moves up and down, seal closure 3 has extensibility, will not pull movable gas hood body 1, fixed petticoat pipe body 2, use the longevity
Life length, is easy to use, easy to maintain, is conducive to promote.
Specifically, the temperature due to flue gas is higher, the seal closure 3 is preferably made of high-temperature-resistant flexible material.In order to
It avoids movable gas hood body 1 when moving up and down, sealing is covered with and pulls damage, influence its service life, so by seal closure 3
Height is set greater than or equal to the stroke that movable gas hood body 1 moves up and down, meanwhile, for the ease of using and installing, sealing
Cover 3 is folding structure.Seal closure 3 and movable gas hood body 1, fixed petticoat pipe body 2 connection type there are many, for the ease of installation
