Description
The invention belongs to the technical field of metallurgy industry sintering machine water-tight equipment, particularly a kind of universal rotation profiling formula head-tail sealing device of sintering machine.
Technical background
Existing sintering machine head-tail sealing device is divided into two kinds of spring and rotation counter weight types basically, wherein the spring sealing be divided into again that pure spring, snap magnet are compound, rubber combined three types of spring.Rotation counter weight type sealing is divided into two types of four connecting rods and simple levers again.Because sintering machine afterbody sintering is finished substantially, sintering combustion layer temperature above the pallet grate bar is up to 1350-1600 ℃, this moment, the tail seal cover board had only 450mm apart from the high temperature place, the temperature at cover plate place also will reach about 700 ℃, the temperature of spring is 360 ℃, rubber the highest heat-resisting be 350 ℃, magnet will be by thorough demagnetization in the time of 760 ℃, the temperature of sintering machine afterbody seal cover board has surpassed the temperature that these materials can bear, and makes the very fast inefficacy of these materials.The slit of spring-like seal cover board and chassis bottom surface is very big, and it is very serious to leak out.Four bars rotation counter weight type seal request higher processing precision and installation accuracy, otherwise be easy to cause interference, this seal flexibility is relatively poor, must set pull bar at seal cover board, adjusting lower link during installation makes cover plate and chassis bottom surface keep the gap of 3-5mm, cause bigger leaking out, just become immobile sealing after the installation.
The middle part supporting type head-tail sealing device of patent 201010128424.8 sintering machines, it is the sealing of a typical simple lever rotation counter weight type, this sealing utilizes the balance principle to have higher flexibility, can vertically moving up and down and reciprocally swinging in horizontal plane of its seal cover board, because the deformation form after the chassis bottom girder is heated is unpredictable, so above-mentioned seal cover board with 2 frees degree can not satisfy the needs of chassis bottom girder distortion, the high temperature lower flexure strain that more can't adapt to chassis has usually formed the bigger trigonum of leaking out between chassis and seal cover board.
Realize that seal cover board fits tightly the chassis bottom girder of distortion, this just requires seal cover board that 3 frees degree must be arranged, namely the forms of motion of seal cover board should be able to satisfy along Z axle (axis vertical with horizontal plane) move up and down and in horizontal plane X, Y-axis rotate (orthogonal two axis in the same horizontal plane) function.
Prior art adopts spring, rubber as elastic component in order to reach above-mentioned requirements mostly, and this class elastic component high temperature failure can not reach satisfied effect.Also there is the lever of employing to add the form of rotating counterweight, wish to rely on seal cover board itself to be out of shape the chassis bottom surface of fitting, all seal cover boards all will be by the top liner plate in fact, the whole plate of middle elasticity, three layers of composition of bottom sealing plate, because the seal cover board antitypy ability after this combination is stronger, can't reach flexibly and be out of shape changing form with the chassis bottom girder at all.Therefore the head and the tail place of the present most of sintering machine problem of leaking out does not still thoroughly solve.
Summary of the invention
The object of the present invention is to provide a kind of universal rotation profiling formula head-tail sealing device of sintering machine, overcome the shortcoming and defect of prior art, make sealing device do forming movement along with chassis bottom girder difformity, significantly reduce the area that leaks out, and keep the seal cover board long-term motion flexibly and wear and tear lessly, effectively prolong service life of chassis and seal cover board.
