Abstract
The utility model discloses a sintering machine head and tail sealing device, which mainly solves the defects that an existing sintering machine head and tail sealing device is overlarege in air leakage rate, short in service life, frequent in sintering machine maintenance and large in labor strength and the like. The sintering machine head and tail sealing device comprises a vertical sealing plate which is arranged on a head portion of a sintering machine or below a tail trolley bottom beam, wherein one end of the vertical sealing plate is arranged above a discharge funnel, the other end of the vertical sealing plate is arranged above an air box, a heave hammer connecting rod mechanism which enables the vertical sealing plate to be lifted and contact with the trolley bottom beam in sealing is arranged below the vertical sealing plate, one end of the vertical sealing plate, which is arranged above the air box is articulated with a transverse sealing plate corresponding to the side wall of the air box, and a sealing brush is arranged between the transverse sealing plate and the side wall of the air box. The sintering machine head and tail sealing device is simple in structure, excellent in sealing effect, and long in service life.
Description
Technical field
The utility model relates to the sintering machine of smelting iron and steel technical field, refers to a kind of device for frame head and tail of sintering sealing device particularly.
Background technology
The early stage sintering machine of building, the frame head and tail sealing metal spring sealing plates that adopt more, the metal spring sealing plate closely contacts with the chassis bottom girder, reaches the purpose of sealing.Owing to have the metal rigidity friction between metal spring sealing plate and the chassis bottom girder, easily cause the contact-making surface injustice, and as time passes, the slit on the contact-making surface is increasing, causes sealing effectiveness very poor, air leak rate of air curtain is mostly more than 40%.
Weight arm formula sealing device is adopted in existing device for frame head and tail of sintering sealing mostly, its structure generally comprises the sealing plate that is arranged on sintering machine head or afterbody chassis bottom girder below, the sealing plate bottom is provided with the weight linkage, and sealing plate upwards lifts under the effect of weight linkage with the sintering pallet bottom girder and contacts and seal.Usually generally leave the gap of 1～3mm between sealing plate and the chassis bottom girder, and be filled with the mountain flesh plate between sealing plate end and the bellows, be used for enhanced leaktightness.The more early stage metal spring sealing plate of the sealing effectiveness of this structure makes moderate progress, its air leak rate of air curtain can be reduced to about 25%, but the mountain flesh plate temperature height, wind speed greatly, for a long time repeatedly under the factor affecting such as bending, use a period of time promptly phenomenons such as breach, fracture can take place, still can not fundamentally solve the problem of leaking out.
Summary of the invention
The purpose of this utility model is exactly the device for frame head and tail of sintering sealing device that a kind of simple in structure, good sealing effect, long service life will be provided.
For achieving the above object, the device for frame head and tail of sintering sealing device that the utility model is designed, comprise the longitudinal sealing plate that is arranged on sintering machine head or afterbody chassis bottom girder below, one end of described longitudinal sealing plate is positioned at the top of hopper, the other end of described longitudinal sealing plate is positioned at the top of bellows, the below of described longitudinal sealing plate is provided with and can makes it upwards lift the weight linkage that contacts with the sealing of chassis bottom girder, the end that described longitudinal sealing plate is positioned at bellows tops is hinged with the transverse sealing plate corresponding to the side-walls of bellows, is provided with sealing between the sidewall of described transverse sealing plate and bellows and brushes.
Further, described transverse sealing plate adopts the eccentric structure of center of gravity to the skew of sealing brush, reliably contacts with the sealing brush to guarantee it.
Further, described sealing brushing tool has the base on the sidewall upper crossbeam that is fixed on bellows, and described base is provided with the rectangle cell body of notch facing to the transverse sealing plate, is filled with the heatproof flexible material in the described rectangle cell body, so that its sealing effectiveness is good.
The utility model has overcome defectives such as existing device for frame head and tail of sintering sealing device air leak rate of air curtain is excessive, service life short, the sintering machine maintenance is frequent, labour intensity is big, its advantage is mainly reflected in following several respects: one, between the sidewall of longitudinal sealing plate and bellows, increase transverse sealing plate and sealing brush, can effectively improve the sealing effectiveness of device for frame head and tail of sintering; They are two years old, both closely paste transverse sealing plate and sealing brush and frictional force is little mutually, the phenomenon of having avoided adopting the mountain flesh plate between existing sealing plate and the bellows and under high temperature and frequent bending situation, having occurred breach, fracture etc. easily, significantly improve the reliability of sealing device, prolonged the life-span that sealing device uses.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Device for frame head and tail of sintering sealing device shown in the figure, comprise the longitudinal sealing plate 6 that is arranged on sintering machine head or afterbody chassis bottom girder below, one end of longitudinal sealing plate 6 is positioned at the top of hopper 7, the other end of longitudinal sealing plate 6 is positioned at the top of bellows 1, the below of longitudinal sealing plate 6 is provided with and can makes it upwards lift the weight linkage 5 that contacts with the sealing of chassis bottom girder, the end that longitudinal sealing plate 6 is positioned at bellows 1 top is hinged with transverse sealing plate 4 corresponding to the side-walls of bellows 1 by hinged-support 3, is provided with sealing brush 2 between the sidewall of transverse sealing plate 4 and bellows 1.Transverse sealing plate 4 can freely swing front and back, thereby strengthens it and seal contacting of brush 2, reaches good sealing effectiveness.
The sealing brush 2 base 2a that have on the sidewall upper crossbeam that is fixed on bellows 1, base 2a is provided with the rectangle cell body 2b of notch facing to transverse sealing plate 4, rectangle cell body 2b links to each other with base 2a by bolt, be filled with heatproof flexible material 2c in the rectangle cell body 2b, this heatproof flexible material 2c can be asbestos material or rubber material.Heatproof flexible material 2c among the rectangle cell body 2b fills smooth, utilizes the bellows suction function that sealing brush 2 is close to transverse sealing plate 4, can strengthen the sealing effectiveness of sealing brush 2.Transverse sealing plate 4 closely pastes mutually with sealing brush 2 and frictional force is little, it is small to wear and tear, even it is slightly lossy, both closely paste all the time mutually under suction function, mountain flesh plate Yin Gaowen and the frequent bending having avoided adopting between present sealing plate and the bellows cause taking place easily phenomenons such as breach, fracture, long service life.
