Abstract
The present invention provides a kind of electric pushrod sealing structure of heating furnace, including furnace body and fire door, fire door is mounted on the entrance being arranged on furnace body, there are gaps between fire door and furnace body, bar shaped seesaw is equipped in the side edge of fire door, bar shaped seesaw is arranged along gap, it is hinged on fire door in the middle part of bar shaped seesaw, the position that gap is corresponded at the one side edge of bar shaped seesaw is fixed with bar shaped strip of paper used for sealing, bar shaped strip of paper used for sealing blocks on gap, several electric pushrods are evenly distributed in another side edge of bar shaped seesaw, the telescopic rod of electric pushrod setting is hinged on bar shaped seesaw, electric pushrod is hinged on fire door.The bar shaped seesaw of setting is blocked bar shaped strip of paper used for sealing on gap using lever principle, and movement response is fast, and small driving force is but able to achieve larger closure power, so that sealing effect is more preferable；The electric pushrod of setting under the driving of electric energy, keep strokes by reaction, avoids the tightness in strip of paper used for sealing damage and gap identical.
Description
Technical field
The present invention relates to box-type heating furnace technical fields, and in particular to a kind of electric pushrod sealing structure of heating furnace.
Background technique
Box-type heating furnace, which is equipped with chamber door, can generally generate gap after chamber door is closed between chamber door and furnace body, need to be to the seam
Gap is sealed.Currently, generally pushing high temperature resistant strip of paper used for sealing to get lodged on gap along gap using hydraulic and air pressure in industry；But in reality
In the application of border, discovery is often pure at gap to block not tight situation due to air pressure and hydraulic unstability；In addition, due to
Thrust mechanism need to be set in many places of strip of paper used for sealing, easily cause the effect of the hydraulically extensible cylinder or air pressure telescoping cylinder close to principal pressure pipe
Power is big, far from pressure pipe hydraulically extensible cylinder or air pressure telescoping cylinder active force it is small, thus cause it is poorly sealed, in addition or because anti-
It should act inconsistent to damage strip of paper used for sealing.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of electric pushrod sealing structure of heating furnace.
A kind of electric pushrod sealing structure of heating furnace, including furnace body and fire door, the fire door are mounted on the furnace body
The entrance of setting, there are gaps between the fire door and furnace body, it is characterised in that: is equipped with item in the side edge of the fire door
Shape seesaw, the bar shaped seesaw are arranged along the gap, are hinged on the fire door in the middle part of the bar shaped seesaw, in the item
The position that the gap is corresponded at the one side edge of shape seesaw is fixed with bar shaped strip of paper used for sealing, and the bar shaped strip of paper used for sealing blocks in the gap
On, several electric pushrods are evenly distributed in another side edge of the bar shaped seesaw, the electric pushrod setting is stretched
Contracting bar is hinged on the bar shaped seesaw, and the electric pushrod is hinged on the fire door.
Further are as follows: the position that the bar shaped strip of paper used for sealing is corresponded on the bar shaped seesaw is installed with accommodation groove, the bar shaped
Strip of paper used for sealing is installed in the accommodation groove.
Further are as follows: the telescopic rod is hinged by hinge assembly and the bar shaped seesaw, and the hinge assembly includes solid
Dead axle and axle sleeve, the axle sleeve are rotatably installed in the fixing axle, and the fixing axle is fixed on the bar shaped seesaw, described
Telescopic rod is fixed on the middle part of the axle sleeve.
Beneficial effects of the present invention: the bar shaped seesaw of setting is blocked bar shaped strip of paper used for sealing on gap using lever principle, is moved
It is fast to make reaction, small driving force is but able to achieve larger closure power, so that sealing effect is more preferable；Drive of the electric pushrod of setting in electric energy
Under dynamic, reaction is kept strokes, and avoids the tightness in strip of paper used for sealing damage and gap identical.
